Xiaoling is treated in the hospital (video screenshot)

　　On the 24th, the topic #15-year-old girl lost only 24.8kg and died # made netizens cry. Xiaoling (pseudonym), a girl, developed from dieting to losing weight into anorexia nervosa, and eventually lost her life because of severe malnutrition, respiratory failure and deep coma.

　　Experts pointed out that anorexia patients often have mental disorders in the front and abnormal behaviors in the back, while anorexia can lead to systemic problems, and solving emotional diseases is the key. Yangzi Evening News/Zi Niu News reporter Xu Qianqian Lu Yanlin

　　The sadness behind the first hot search … …

　　The doctor was shocked when he took the CT scan: it was as light as lifting a quilt.

　　One afternoon in March, the transfer center of Shenzhen Children’s Hospital received help from a hospital in Dongguan. Xiaoling (pseudonym), a 15-year-old girl, was severely malnourished and had respiratory failure, and she had lost consciousness.

　　Xiaoling’s father, who was transferred to the hospital with the car, told the doctor that Xiaoling had not eaten anything for nearly 50 days since the third day of the new year, only drinking water. I was delirious at home last week and was rushed to hospital.

　　Xiaoling is 165 cm tall and weighs only 24.8 kg. This weight is not even as good as that of some junior children.

　　The doctor looked at Xiaoling carefully, but she didn’t breathe spontaneously at all, and her mouth was bleeding all the time. The biggest problem is that Xiaoling’s pupils are unequal and her reflection on light disappears. "This is a very bad signal", the pupil is controlled by the brain stem, and the pupil is unresponsive, which means that the brain stem has been damaged and may not wake up.

　　After Xiaoling was transferred to Shenzhen Children’s Hospital, she was immediately pushed to take a CT scan of her brain. As soon as the doctor passed, she was shocked: It’s so light, it feels like lifting a quilt.

　　So thin, it’s really skin and bones. So that when I went to bed, the doctor repeatedly told me to be careful, slow down, and especially be careful of fractures.

　　Girls lose weight for love at first.

　　Mom recalled that Xiaoling was the fattest when she was in the sixth grade, about 104 kg. When she entered junior high school, her family found that she was "conscious of losing weight". "She told us that she didn’t eat with oil, not at all."

　　Mom said that according to classmates, Xiaoling has a crush on a boy, but that boy likes a girl thinner than her.

　　Later, there was another "pusher" on the road to losing weight: the psychology of comparison. Once, Xiaoling saw another girl in the class eating only vegetables and decided that she was losing weight. Xiaoling can’t accept the fact that I am more beautiful than that classmate and have better grades than her, but she is thinner than me!

　　Slowly, Xiaoling didn’t eat rice and staple food, and finally she didn’t eat at all but drank water. Dieting turned into a hunger strike.

　　In the next year and a half, Xiaoling repeatedly fasted until she fell into a coma and her life was dying. When she was transferred to a hospital in Dongguan, her grandmother, who had brought her up in one hand, cried her heart out and refused to let her granddaughter get on the ambulance: "Don’t send her away, don’t let her die outside." This situation has made many people cry.

　　Why did parents not intervene in advance?

　　In fact, Xiaoling’s parents forced her to go to the hospital many times, but the first time she went to Xiaoling, she tried to jump out of the car and opened the door four or five times. When she arrived at the hospital, Xiaoling was forcibly dragged into the ward, so she hit her head with a shower and tried to jump out of the window … …

　　There is another reason why parents are helpless. Xiaoling has anorexia nervosa, which is what we often hear. This disease is one of the mental diseases with the highest mortality rate, and even psychiatrists have to smell it.

　　At first, Xiaoling’s father found many pictures of anorexia on the Internet to show her. "If you go on like this, you will get anorexia." But Xiaoling vowed: "Dad, don’t worry, I won’t get anorexia."

　　After losing weight for one year and three months, Xiaoling found that she didn’t have her period and was taken to Shenzhen Children’s Hospital for examination by her parents. She was diagnosed as anorexia nervosa.

　　Xiaoling’s mother said: "At first, she wanted to reduce her weight to more than 50 kilograms, but when she reached her fifties and sixties, she had no bottom line and only became thinner and thinner."

　　Before being sent to hospital, he had suffered from 14 diseases.

　　Before Xiaoling was transferred to Shenzhen Children’s Hospital, there were 14 kinds of diseases in her body, all organs in her body were damaged or even failed, and her brain might never wake up.

　　Xiaoling didn’t wake up at last. When the doctor told the parents "I tried my best to make a choice", my father choked: "I can’t bear to give up."

　　After much consideration, my parents decided to let go, and finally my mother accompanied Xiaoling through the last journey … …

　　After Xiaoling’s story boarded the hot search, it triggered a discussion among netizens.

　　Some netizens said that health is the most important thing; More netizens feel that society should advocate healthy aesthetics.

　　Connection expert

　　Dieting to lose weight is difficult for many people to stick to for a long time, but once they get past that point, dieting becomes a hunger strike, and some symptoms of anorexia nervosa gradually appear, which is enough to make people turn pale. So how can we avoid anorexia caused by excessive weight loss?

　　Yangzi Evening News/Zi Niu News reporter connected relevant experts — —

　　Anorexia patients often have mental disorders in the front and abnormal behaviors in the back.

　　Wang Ting, director of the Department of Psychiatry, Nanjing Hospital of Traditional Chinese Medicine, said in an interview that such diseases belong to mental and psychological diseases with eating disorders as the main factor. Patients have unusual ideas and "cruel and excessive" behaviors about their own weight and body shape. For teenagers, they usually appear at the same time with depression and bipolar disorder. "They are not satisfied with their weight, figure or appearance, and will do whatever it takes to try to prove themselves, and feel that they are doing it themselves. Therefore, there will be situations in which Xiaoling is unwilling to go to the hospital for treatment, resistance and self-harm. Modern research has suggested that changes in social culture, including aesthetics, peer induction and demonstration, and patients’ brain structure and function may be induced.

　　Although the loss of life due to weight loss is a real case, there are not a few people who have "appearance anxiety" nowadays, and patients who have health problems after extreme weight loss are not uncommon. Miao Weifeng, chief physician of the Department of Spleen and Stomach Diseases of Nanjing Hospital of Traditional Chinese Medicine, has received several patients with anorexia nervosa, which is regrettable. "In fact, many patients are already very thin. There is a 19-year-old girl, who is about 70 pounds tall and 6 meters tall, but she still has the idea of losing weight." Miao Weifeng recalled that there was another female patient who was going to be 60 years old. Because of anorexia, it was almost 10 years before and after seeing a doctor, and she was already in a state of severe malnutrition when she saw a doctor. "We later found that we gave her nutritional support during the treatment, but in order not to make herself fat, she even secretly dumped the nutrient solution we hung for her from the infusion pimp."

　　At present, the etiology of anorexia nervosa has no clear mechanism, which is generally related to personality and environmental factors, and the genetic factors are not clear. Shen Diwen, deputy director of the Department of Medical Psychology, Nanjing Gulou Hospital, also said: "Patients with anorexia nervosa tend to pursue perfection, especially for their body shape and appearance. In addition to dieting, they may spit out what they have eaten by withholding and other methods. But in fact, when these behavioral abnormalities are found, it is often necessary to take compulsory measures to intervene and stop, and seek professional treatment from doctors. "

　　Anorexia can lead to systemic problems, and solving emotional diseases is the key.

　　Nutrition is not enough if you don’t eat, and emaciation is the most common manifestation. However, at this time, "emaciation" may not be regarded as beauty, but a pathological symptom. "There is a problem with emotions, which will have an impact on whether it can be digested or absorbed." Miao Weifeng told reporters that from the perspective of Chinese medicine theory, although the related symptoms of anorexia nervosa are mainly located in the spleen and stomach, it is actually closely related to the liver, heart and kidney, and it is a systemic disease.

　　Miao Weifeng further explained that serious weight loss may cause many problems to the body, leading to abnormal hormone levels including sex hormones in the body. "Women are most likely to have menstrual disorders and even amenorrhea, which may affect fertility after a long time. For men, long-term malnutrition and nutritional disorders will also lead to systemic weakness. "

　　At the same time, experts pointed out that there will be a lack of certain elements in severely malnourished people, which will also lead to other secondary diseases. "For example, vitamin B deficiency, aphtha and peripheral nerve inflammation may occur." Shen Diwen introduced that at present, the main treatment for anorexia nervosa is psychotherapy combined with antidepressant treatment. Psychotherapy refers to changing cognition to promote better positive behavior, while the latter mainly improves appetite demand by adjusting emotions and compulsion. In addition, nutritional therapy should be added when necessary to prevent malnutrition.

　　Deformed "thinness is beauty" is not desirable. Losing weight by "fasting" without science will slowly devour you who are addicted.

　　I hope Xiaoling’s tragedy will be seen by all those who want to lose weight. Don’t repeat the same mistakes and don’t make family and friends sad.

　　The 20th press conference on epidemic prevention and control in COVID-19 was held.　

　　The start of school continues to be postponed.　

　　When does school start? Determine after the epidemic situation is effectively controlled.

　　On February 29th, the Information Office of the provincial government held the 20th press conference on the prevention and control of COVID-19 epidemic in our province. Spokesmen of the Provincial Health and Health Commission, the Provincial Department of Education and other units reported on the progress of epidemic prevention and control and medical treatment in our province, and responded to social hot issues such as students’ return to school and employment.

　　Among the cured cases, the participation rate of traditional Chinese medicine was 99.31%.

　　Zhang Ruoshi, deputy head of the comprehensive group of the Office of the Provincial Epidemic Prevention and Control Headquarters and deputy director of the Provincial Health and Wellness Committee, informed that as of 24: 00 on February 28th, the province had reported a total of 1,272 confirmed cases in COVID-19, and 1,161 cases were discharged, with a cure rate of 91.27%. In medical treatment, our province implements a dual-tube bed of Chinese and western medicine, and the severe rate of Chinese medicine diagnosis and treatment guidance is 100%. Among the confirmed cases, the participation rate of Chinese medicine is 98.74%, and among the cured and discharged cases, the participation rate of Chinese medicine is 99.31%.

　　Li Suyun, deputy head of the medical treatment expert group of Henan Province in COVID-19 and vice president of the First Affiliated Hospital of Henan University of Traditional Chinese Medicine, said that for mild and ordinary patients, early intervention of traditional Chinese medicine can effectively prevent the disease from transforming into severe and critical diseases; In the treatment of severe and critical diseases, it will win time for the rescue and improve the success rate of treatment; In the rehabilitation period, it is conducive to the rapid recovery of patients.

　　Children’s illness affects people’s hearts. Jin Zhipeng, director of the Department of Internal Medicine of Henan Children’s Hospital and director of the Children’s Intensive Care Unit, said that the hospital uses integrated traditional Chinese and western medicine to implement precise treatment and individualized care. As of 24: 00 on February 28th, 5 children with COVID-19 were admitted to the isolation ward of our hospital, 3 of them have recovered and discharged, and 2 are still under treatment, all of which have improved obviously.

　　The starting time will be determined after the epidemic situation is effectively controlled.

　　When to start school is a common concern of teachers, students and parents. Diao Yuhua, deputy director of the Provincial Department of Education, said at the press conference that the start time of schools of all levels and types in our province will continue to be postponed. After the epidemic situation in our province is effectively controlled, the specific start time will be unified and announced to the public one week in advance.

　　Combined with the reality of our province, the Provincial Department of Education has formulated a basic plan for returning to school in an orderly manner when the conditions for starting school are met: primary and secondary schools, kindergartens and secondary vocational schools adhere to the principle of "one place, one policy", and start school by stages and in batches in different regions. In principle, the third grade of ordinary high school is unified in the province; In the third grade of junior high school, except Zhengzhou, Nanyang and Xinyang, the opening time of other provinces and municipalities is unified; Colleges and universities adhere to the principle of "one school, one policy" and territoriality, and comprehensively consider many factors such as "first in the province, then outside the province" and "first in the local area" to accurately formulate the plan for returning students to school; Secondary vocational schools with foreign students (including other provinces) can refer to the start time of colleges and universities. At present, all local schools should accurately grasp the health status and whereabouts of teachers and students, accurately formulate the work plan for students to return to school, and do their best to prepare for the start of school.

　　Job fairs are "moved" from offline to online.

　　At present, it is the key node for college graduates to find jobs. This year, the number of college graduates in our province is expected to reach 660,000. In order to minimize the impact of the epidemic on employment, our province has "moved" the job fair from offline to online, launched the "Spring Online Recruitment Month for College Graduates in 2020", and pushed recruitment information through the website of the Provincial Department of Education and other channels, which has provided more than 50,000 jobs; In March, the province’s education system will also launch 220 large-scale campus network double-election activities.

　　Broaden employment channels. Organize colleges and universities to guide employers to tap their own potential by sending letters to employers, provide more jobs for graduates, strive to undertake more national enrollment expansion tasks, and focus on expanding the enrollment of disciplines and majors that are urgently needed for economic and social development and have high employment quality in our province.

　　Optimize employment services. Simplify procedures, implement online employment procedures and academic qualifications certification, and keep accounts and files in school for two years for college graduates who have not implemented their work units when they leave school; Open the "micro-guidance" function on the employment and entrepreneurship service cloud platform, and share more than 300 high-quality employment and entrepreneurship guidance courses for free.

　　In the next step, the Provincial Department of Education will cooperate with 12 departments including the Provincial Development and Reform Commission to carry out the "New Era and New Dream" public welfare assistance action for employment and entrepreneurship. Facing the national strategy and key areas, we will expand jobs, implement the special post plan for rural teachers, implement grassroots employment projects such as Selected Graduates and "three supports and one support", and do a good job in college students’ joining the army.

In order to do a good job in the vaccination work in Covid-19 of the whole army, further popularize the vaccination knowledge, and ensure that the vaccination work of the whole army is scientific, rigorous, safe and standardized, and vigorously and orderly and effectively promoted, recently, the reporter interviewed experts related to the joint prevention and control mechanism of the army in response to public health emergencies.

Reporter: What is Covid-19 vaccine and what kinds are there at present?

Expert: Covid-19 vaccine, called novel coronavirus preventive vaccine, is an innovative vaccine to prevent and control diseases caused by Covid-19 infection. Domestic Covid-19 vaccine research and development technologies are mainly divided into five types, namely: inactivated vaccine, adenovirus vector vaccine, attenuated influenza virus vector vaccine, recombinant protein vaccine and nucleic acid vaccine. Up to now, there are four kinds of vaccines in China, such as inactivated vaccines from Sinopharm Group Co., Ltd. "Zhongsheng Wuhan" and "Zhongsheng Beijing", inactivated vaccines from Beijing Kexing Zhongwei Biotechnology Co., Ltd. and adenovirus vector vaccine developed by Academy of Military Sciences and Kangxinuo Company, which have been approved for conditional listing. The recombinant protein vaccine jointly developed by Institute of Microbiology of China Academy of Sciences and Anhui Zhifeilong Kema Company agreed to be used urgently after evaluation and demonstration.

Reporter: Is it necessary for the general population to get novel coronavirus vaccine?

Expert: novel coronavirus is a new virus, and almost everyone is susceptible to novel coronavirus, so it is very necessary to get vaccinated. As a group that needs to perform all kinds of tasks at any time, military personnel should be vaccinated except for contraindications.

Reporter: What are the main features of recombinant novel coronavirus vaccine (adenovirus vector) compared with other COVID-19 vaccines approved by China?

Expert: At present, COVID-19 inactivated vaccine needs to be vaccinated twice in the whole process, and it is recommended that the interval between two doses should not be less than 28 days. Those who need to complete the whole process of COVID-19 inactivated vaccine as soon as possible because of going abroad or working in high-risk areas can be vaccinated twice with COVID-19 inactivated vaccine at the shortest interval specified in the vaccine instructions; The recombinant protein vaccine jointly developed by Institute of Microbiology, China Academy of Sciences and Anhui Zhifeilong Kema Company needs to be inoculated three times. Inoculation is to make the antibody reach a certain level to resist the disease. Generally speaking, inactivated vaccines need to be vaccinated many times, and the immunity should be strengthened regularly to achieve sufficient antibody titer in the body. The first vaccination usually does not provide protection, and the protective immune response usually occurs after the second dose of vaccination.

Recombinant novel coronavirus vaccine (adenovirus vector) only needs to be inoculated with one dose, which can produce cellular immunity and humoral immunity after 14 days of inoculation, providing double protection for human body. It is the only single-dose COVID-19 vaccine approved for use in China.

Reporter: What is the principle of adenovirus vector technology?

Expert: human adenovirus type 5 (Ad5) is a common respiratory virus. After being modified, Ad5 will not replicate in human body. Insert the gene encoding Covid-19 spike protein (S protein) into Ad5 vector, which is equivalent to rocket and S protein gene is equivalent to satellite. The vector carries the S protein gene into human cells to synthesize Covid-19 S protein, and S protein is used as antigen to stimulate the immune response of the body. Only Covid-19’s S protein enters the human body, and there are no other Covid-19 components.

Reporter: What is the protective effect of recombinant novel coronavirus vaccine (adenovirus vector) and its protective effect on Covid-19 mutant?

Expert: At present, the data of global phase III clinical trials show that after 14 days of single injection of recombinant novel coronavirus vaccine (adenovirus vector), the protective effect on severe COVID-19 is 95.5%, and the overall protective effect on all symptoms of COVID-19 is 68.8%. The results of neutralizing antibody cross experiment showed that the vaccine had protective effect on Covid-19 mutant.

Reporter: How safe is the vaccine in Covid-19?

Expert: Covid-19 vaccines, like other vaccines, have a series of safeguards for quality and safety management, and there are clear requirements in the process of vaccine research and development and production. Vaccines must undergo strict animal experiments and clinical research before they are registered, and a strict batch issuance system should be implemented before they are used. Therefore, the vaccines approved by the state for marketing are all safe and effective to meet the qualified standards.

The recombinant novel coronavirus vaccine (adenovirus vector) was approved for conditional marketing in National Medical Products Administration based on the results of Phase III clinical trials conducted by more than 40,000 people in five foreign countries, and the vaccine was safe. Up to now, hundreds of thousands of people have been vaccinated, and no serious adverse reactions related to vaccination have been found.

Reporter: What are the main adverse reactions that may occur after the recombinant novel coronavirus vaccine (adenovirus vector) is inoculated?

Expert: Like any other vaccine, there may be some common adverse reactions after inoculation with recombinant novel coronavirus vaccine (adenovirus vector). After summarizing all the adverse reactions collected in the clinical trials of phase I, II and III vaccines and in emergency use, the common adverse reactions at the inoculation site are pain, swelling, itching, erythema and induration. Common systemic adverse reactions include fever, headache, fatigue, myalgia, lethargy, nausea and diarrhea. The severity of adverse reactions observed in this series of clinical trials is mainly Grade 1 (mild), and the incidence of adverse reactions of Grade 3 and above is 7.40%. For those with fever, antipyretic drugs can be taken, and other common adverse reactions generally do not need special treatment, and usually can be relieved within 48 hours. If the symptoms are serious or you can’t judge the severity by yourself, you should seek medical advice in time.

Reporter: Who are the people who are not allowed to vaccinate in Covid-19?

Expert: Vaccination contraindications for vaccines in Covid-19 must be strictly observed in Covid-19’s vaccine instructions. Usually, people who are seriously allergic to vaccines or any ingredients in vaccines are contraindicated. For patients with fever, acute diseases and acute authors of chronic diseases, they generally belong to the object of suspension of vaccination.

Reporter: Can people in allergic period be vaccinated with recombinant novel coronavirus vaccine (adenovirus vector)?

Expert: Allergy is an important factor for doctors to consider when vaccinating. People who are allergic to vaccines or vaccine ingredients and have had allergic reactions to vaccination in the past are not suitable for vaccination; People with other serious allergic history (such as asthma, severe eczema, etc.) are not recommended to be vaccinated; For allergic people with pollen allergy, nasal congestion, runny nose or slight rash, it is recommended to stagger the allergic period, and the mild symptoms can be vaccinated according to the doctor’s advice.

Reporter: Can cancer patients and people with chronic diseases be vaccinated with recombinant novel coronavirus vaccine (adenovirus vector)?

Expert: People with nervous system diseases and immune system diseases are not suitable for vaccination. Basic patients such as diabetes and hypertension that can be controlled by drugs can be vaccinated during the stable period. For cancer patients, it is necessary to consult oncologists and determine whether they can be vaccinated according to the drug use.

Reporter: What are the precautions before and after Covid-19 vaccination?

Expert: Before vaccination, the vaccination doctor will ask about the health status, please tell the relevant information truthfully; After the inoculation is completed, it is necessary to keep on-site observation for 30 minutes, keep the injection site dry on the day of inoculation, pay attention to personal hygiene and arrange rest properly; Avoid contact with previously known allergens and common allergens within one week after inoculation, and try not to drink alcohol, eat spicy food or seafood. It is recommended to have a light diet and drink plenty of water.

Reporter: If there are serious adverse reactions after vaccination with Covid-19 vaccine, how should I report and handle them?

Expert: According to past experience, acute adverse reactions after vaccination usually appear within 30 minutes after vaccination. Please keep under observation as required and inform the doctor at the vaccination site in time. If there are serious adverse reactions after leaving the inoculation site, you should seek medical treatment in time and report to the doctor at the inoculation site.

Reporter: How long is the immune persistence of Covid-19 vaccine? Is it necessary to strengthen immunization?

Expert: At present, the immunization program of recombinant novel coronavirus vaccine (adenovirus vector) is one dose, and the observation of immune persistence after single dose vaccination is still in progress. The current data prove that it is effective within at least 6 months. Previously, the vaccine research and development team observed the immune persistence of Ebola vaccine using the same adenovirus vector technology and found that it still had a high antibody level after two years of inoculation.

Reporter: Can recombinant novel coronavirus vaccine (adenovirus vector) and inactivated COVID-19 vaccine be used together?

Expert: At present, there is no relevant information about alternative vaccination and combined application. Please refer to the national policy guidance and COVID-19 vaccine instructions.

Reporter: Will nasopharyngeal swab test positive for nucleic acid after inoculation with recombinant novel coronavirus vaccine (adenovirus vector)?

Expert: No. The nucleic acid test is Covid-19 gene, and the current vaccine will not cause COVID-19, nor will it make Covid-19 nucleic acid test positive because of vaccination.

Reporter: Can Covid-19 vaccine be inoculated with other vaccines such as HPV vaccine, influenza vaccine and rabies vaccine?

Expert: It is not recommended to vaccinate with other vaccines at the same time. It is recommended to vaccinate with other vaccines at least 2 weeks apart to minimize unexpected interaction, and at the same time, it is necessary to closely observe the reaction after vaccination.

Reporter: Is it necessary to vaccinate people who have had COVID-19 or who have no symptoms?

Expert: The existing research data show that it is rare to get reinfected in Covid-19 within 6 months after infection. Previous COVID-19 virus-infected people (patients or asymptomatic infected people) can receive one dose after 6 months on the basis of full notification.

Reporter: Do I still need to wear a mask after Covid-19 vaccination?

Expert: Before the population immune barrier is established, even if some people are vaccinated, everyone’s awareness of prevention and control and prevention measures cannot be relaxed. On the one hand, the success rate of vaccine immunization is not 100%, and a small number of vaccinated people may get sick during the epidemic period, which is related to the characteristics of the vaccine itself and the personal physique of the recipients; On the other hand, in the absence of an immune barrier, Covid-19 is still easy to spread.

Reporter: Do you need to check the antibody production? How to check the antibody? If it is negative, do you need to replant?

Expert: It is not recommended to check antibodies. The production of specific antibodies in human body is generally obtained by natural infection or vaccination. It is suggested that anyone who meets the vaccination conditions should be vaccinated as long as they are not clearly infected with Covid-19 or have suffered from COVID-19, and there is no need to test antibodies before and after vaccination.

Reporter: Do you still need to do nucleic acid testing after Covid-19 vaccination?

Expert: Vaccination can reduce the risk of infection to a certain extent, but the protective effect of any vaccine can not reach 100%. If necessary, we should still cooperate with relevant departments to carry out nucleic acid testing.

In order to further improve residents’ health literacy and promote the healthy development of the whole society, yesterday morning, the Municipal Aiwei Office held a special publicity campaign for the 36th Patriotic Health Month.

At the event site, the Social Affairs Bureau of Yuntai Mountain Scenic Area organized medical staff in the jurisdiction to conduct on-site free clinics and distributed more than 1,000 health guidance manuals.

I hope that through rich activities, the general public and friends will actively participate in the patriotic health month, starting from me, starting from now, and starting from the small things around us to jointly create a healthy, beautiful and livable urban environment.

CCTV News:The State Council Press Office held a regular briefing on the State Council policy at 3 pm on July 17th. Wang Jiang, Vice Minister of Industry and Information Technology, and the relevant person in charge of the Ministry of Justice introduced the Regulations on the Protection of Payment for Small and Medium-sized Enterprises and answered questions from reporters.

Wang Jiangping introduced that small and medium-sized enterprises are the most dynamic enterprise groups, an important support for expanding employment and improving people’s livelihood, and an important foundation for building a modern economic system and achieving high-quality economic development. In recent years, influenced by the complicated and changeable economic situation at home and abroad and the downward pressure on the economy, the payback period of enterprise accounts has been extended, and some organs, institutions and large enterprises have the problem of owing money to small and medium-sized enterprises to varying degrees, which has seriously infringed on the legitimate rights and interests of small and medium-sized enterprises, aggravated their financial difficulties and even endangered their survival. Small and medium-sized enterprises have strongly reflected this and attracted wide attention from all sectors of society.

Special feature of 1905 film network　The 2024 National Film Work Conference was held in Beijing from April 18th to 19th. Guided by Socialism with Chinese characteristics Thought of the Supreme Leader in the New Era, the conference thoroughly studied and implemented the cultural thought of the Supreme Leader and implemented the spirit of the important instructions of the General Secretary of the Supreme Leader on film work.

Hu Heping, Vice Minister in charge of daily work of Publicity Department of the Communist Party of China, attended the meeting and delivered a speech. Responsible comrades in charge of film work in the Propaganda Department of the Party committees of all provinces, autonomous regions and municipalities, responsible comrades in the film department, and representatives of state-owned and private film units and film professional colleges attended the meeting.

Management departments at all levels, front-line experts and scholars in the industry, industry associations and enterprises have jointly studied the latest ideas of the supreme leader’s cultural thoughts and industry management, and exchanged and shared the film work experience in 2024. In this programme, Professor Zhifina from China Academy of Art is invited to focus on the 2024 National Film Work Conference with us.

As a participant, Zhifina came to ""as soon as after the meeting and conveyed the spirit of the meeting to everyone. "This is not only a learning exchange meeting, but also a deployment summary meeting. Participants share their feelings about the development of the industry with rich emotions and express their opinions on promoting the development of the industry." Zhifina said.

The meeting pointed out that although China’s films have made good recovery achievements, there is still a certain gap with the development of high standards. Film workers should fully respect artists, doers, consumers and reformers, respect the laws of industry, market, management and communication, respect the reality of industry development, social development and international environment, be innovative in content and inclusive in extension, carry forward the main theme and spread positive energy with an open attitude.

The meeting focused on three key words: reform, consumption and creation, summed up the reasons and achievements of the film industry’s recovery since the 20th National Congress of the Communist Party of China, and made clear and comprehensive arrangements for the future film work.

Reform is the first priority.

The current policy framework of the film industry was formulated in the era of lack of domestic film development. According to the data, in 2003, there were 1800 screens and 1024 cinemas in China, with a box office of 990 million. By the end of 2023, the number of cinemas in China will reach 14,000, with 86,310 screens and a box office of 54.915 billion yuan. In the past 20 years, the number of cinemas has increased by 14 times, the number of screens has increased by 47 times, the film output has increased by 10 times, and the number of people watching movies has increased by 37 times. Obviously, the policy aimed at the era of scarcity is no longer applicable to guide the current situation of excessive hardware development in the industry, and the policy reform of the film industry is imminent.

On how to reform the film market, Zhifina put forward the "three respects" principle of respecting the laws of art, market and management.

Respect the law of art

First of all, respect the laws of art. Film workers should re-understand the open connotation of the main theme and respect artists and creators.

Respect for industrial laws

Second, respect the laws of industry. In-depth reform of marketization and industrialization of the film industry. At the distribution level, more film resources can reach the audience by means of sub-line distribution, sub-regional distribution, focus distribution, classified distribution and sub-fare distribution. In terms of publicity, traditional film companies should learn to make use of the communication advantages of the Internet, so that publicity can be effectively converted into movie attendance and more audiences can enter the cinema.

Respect the management law

Third, respect management rules. The management department should change the thinking of political achievements, actively accumulate experience, speed up the administrative examination and approval, take the survey data of movie audiences as a guide, put the focus of the reform on promoting audience consumption, and avoid using the "three axes" policy of making movies, building bases and holding festivals.

It is urgent to promote consumption and expand domestic demand.

Another key point in the meeting is to increase the audience under 25. The data of three surveys of movie audiences in 2011, 2015 and 2021 show that the average age of movie audiences has increased significantly. Zhifina explained: "I participated in the three surveys of movie audiences and found that the movie audience did not flow on a large scale. From 2011 to 2021, it was still a group of audiences, so how to attract new young audiences into the cinema is an important issue."

In order to promote the consumption of the film and television industry and expand the internal demand of the film industry, we must first ensure the content quality, formulate a reasonable price strategy, let the audience buy cheaper movie tickets, attract new audiences to enter the market, and reduce the average age of the audience. Secondly, we should improve the publicity and marketing mechanism of the film industry, so that the audience can truly understand and fall in love with the film.

Creation is the foundation of film.

Film creation that responds to the needs of the audience is the foundation of filmmakers. At this stage, the movie audience’s demand for watching movies has expanded to absorb emotional value and emotional resonance. Zhifina thinks: "Movies should provide more power to warm people’s hearts. A good movie can affect people’s life." The current film creation should fully respond to the needs of the audience and strengthen the emotional connection with the audience.

Only by adhering to the development principle of "keeping integrity, innovating and accelerating reform", embracing new technologies, opening up new markets and enhancing the sense of responsibility and mission can China’s film market flourish and remain invincible in the long-term competition.

　　At present, mycoplasma pneumoniae, influenza, streptococcus pneumoniae and other respiratory pathogens are in the epidemic stage, many people are recruited, and some people have mixed infections with multiple pathogens. What is mixed infection? Who is prone to mixed infection? How to prevent it? Look at the authoritative answer.

　　What are the more popular pathogens at present?

　　Autumn and winter are the seasons with high incidence of respiratory infectious diseases in children. In addition to mycoplasma pneumoniae infection, influenza virus, adenovirus, respiratory syncytial virus and so on have appeared one after another. This is in line with the previous fashion trend.

　　At present, the most popular pathogens are mycoplasma pneumoniae, influenza virus, respiratory syncytial virus and streptococcus pneumoniae. These respiratory tract infections usually have symptoms such as cough, expectoration, runny nose, fever and general fatigue.

　　Mixed infection means that more than two pathogens are infected at the same time. Most clinical "mixed infections" are mainly the combination of viruses, bacteria and mycoplasma.

　　Who is prone to mixed infection?

　　Children, the elderly and people with basic diseases are susceptible to respiratory diseases, and they are also more prone to mixed infection of multiple pathogens. Children should strengthen protection, avoid cross-infection, avoid contact with patients, and reduce the chance of being infected.

　　There is mixed infection, how to treat it?

　　After mixed infection, early differential diagnosis is very important. Now most medical institutions can detect influenza virus, Covid-19 and mycoplasma, which is helpful to implement targeted treatment as soon as possible.

　　If influenza or Covid-19 is complicated with mycoplasma infection or bacterial infection, it is usually necessary to add antibacterial drugs, and at the same time give symptomatic treatment such as fever reduction, cough relieving and phlegm elimination, but the use of antibacterial drugs needs the guidance of doctors. For most patients, after taking medicine, drinking plenty of water and taking enough rest according to the doctor’s advice, the condition can be relieved in 1 to 2 weeks.

　　If the fever lasts for more than 72 hours or the body temperature exceeds 40℃, or if you cough frequently, it will affect your normal life, or if you have symptoms such as chest pain, wheezing, hemoptysis, shortness of breath or dyspnea, poor spirit and frequent vomiting, you should go to the hospital in time.

　　How to prevent mixed infection?

　　Vaccination against influenza is a safe and effective way to prevent influenza, which can effectively reduce the risk of influenza virus infection, hospitalization and serious illness and death in autumn and winter. It is recommended that all ≥ People who are 6 months old and have no vaccination contraindications are actively vaccinated against influenza.

　　In daily life, you should wash your hands frequently, open more windows for ventilation, cover your nose and mouth as much as possible when coughing or sneezing, and wear a mask when necessary. During the epidemic period of respiratory diseases, try to reduce going to places where people gather.

　　Keep enough sleep and eat high-quality protein and foods rich in vitamin A and vitamin C in your diet. Do a good job in family hygiene. If any family member has respiratory tract infection, pay attention to isolation. People with chronic respiratory diseases or other chronic basic diseases should try their best to reduce going to places where people gather.

Blind people dare not take the blind road: I don’t know what is waiting for me ahead.

On the sidewalks of the city, there is always a strip of blind roads. For people with visual impairment, the blind road is a "static eye". They judge the direction of the road through the detection of the blind road brick by their feet and blind poles. However, in an interview recently, the reporter found that there are many obstacles on the blind road in Shijiazhuang street, which seriously affects the travel of the blind and even brings them danger.

phenomenon

The bike is parked on the blind road.

On both sides of the blind road on the street sidewalk, a row of cars stopped on one side, and a row of bicycles and electric cars stopped on the other side. The rear wheels of non-motor vehicles occupied a large part of the blind road. This is the scene that the reporter saw on a service road south of the intersection of Ping ‘an Street and Huai ‘an Road on the afternoon of July 31st.

"The blind road has become like this. We people with healthy eyesight have to be careful when passing. How can the blind get by?" A gentleman passing by here lamented.

On the streets of Shijiazhuang, such a situation is not uncommon.

The blind road in front of northland supermarket in Zhaiying South Street is occupied by a row of bicycles and electric cars. There was a special parking space for non-motor vehicles in front of the supermarket, but because the parking space was full, someone parked the car directly on the blind road for convenience.

There is also a phenomenon that the blind road is occupied by bicycles next to the entrance of Beiguo Mall Station and Northern Song Dynasty Station on Metro Line 1. Bicycles are parked in disorder, which not only occupies the blind road, but also blocks the pedestrian passage. Many pedestrians have no choice but to bypass the road.

In front of the book building, some cars parked directly on the blind road, and they stopped in a row, completely blocking the blind road.

Roadside facilities play "edge ball"

In some places, obstacles have been erected on blind roads.

On a section of service road near Jianhua Street on Donggang Road, a row of iron piles with a height of 20-30 cm were erected close to the blind road. In some places, even irons stood on the other side of the blind road, and a short section of iron piles even circled the blind road into the parking lot. The motor vehicles parked here just cover the blind road. A lady who lives nearby said worriedly, "For blind people, I’m afraid they will trip on such a blind road."

On Ping ‘an Avenue, there is a small iron house next to the blind road, which also makes people worry about the blind people passing through here, fearing that they will bump into the house when they walk.

Mahjong table on the blind road.

In addition to some vehicles or facilities occupying blind roads, some citizens also occupy blind roads when setting up stalls or having fun.

On Zhaiying South Street, several citizens put tables on the blind road and played mahjong, with some onlookers watching the battle.

The citizens who played mahjong said that they didn’t realize that they occupied the blind road. They just felt that it was cool under the tree and few people passed by, so they played mahjong here.

The reporter also saw the interruption of blind roads in many road sections. On a section of Ping ‘an Avenue, not only the blind road was interrupted, but also a manhole cover was tilted, which simply became a "trap".

affect

Blind people usually dare not go blind.

Wang Huaijie is the owner of a blind massage shop on Jianming North Road. He told reporters that he was hit by an obstacle on the blind road when he was walking. This kind of thing has happened many times. "Once in the street in front of my shop, a sorbet seller put the sorbet box on the blind road, and people were not around. I couldn’t see it, so I went straight ahead and bumped into the sorbet box. " Wang Huaijie said, fortunately, he walked slowly, and there was nothing serious, but he was shocked at that time.

"On the road in the middle of the tree, inclined cables with telephone poles pass through the blind road, high and low. Walking through there, you often stumble when you meet the low ones, and sometimes there are wires on the high ones. Once I went to my sister’s house and passed there, and I was scratched by wire. I don’t know who to look for, I can only admit that I am unlucky. " Wang Huaijie said, "Some blind roads are too close to tree pits or green areas, so we can’t see them. It’s easy to walk askew. If you accidentally step into a mud pit on rainy days, your shoes and socks are wet."

Speaking of the impact of obstacles on the blind, Wang Huaijie has a lot to say. He said that some vendors will occupy blind roads, which is not bad, and stall owners will remind themselves when they see it. The most troublesome thing is that sometimes bicycles or other sundries will appear on the blind road, and no one will remind him that he is often tripped or injured.

Mr. Geng, the owner of another massage shop, said that he also had the experience of almost tripping over wires. Sometimes the blind road disappears when walking, leaving him at a loss. "Now I don’t take the blind road, because I don’t know what’s waiting for me in front, or it’s safer to walk by the curb." Mr. Geng’s words represent the voices of many blind people. They usually prefer to walk along the road in the non-motor vehicle lane when they go out, thinking it is safer. Some blind friends simply avoid traveling alone, but they really need to go out and let their families accompany them.

It is understood that blind people need to constantly compose pictures in their minds when walking, and build a three-dimensional picture with the feeling and hearing under their feet. The blind stick in their hands is like a detector, and they can check the road conditions 1 meter away at any time. When there is an obstacle at a certain point in this picture, it is necessary to detour, and this obstacle point will stay in this three-dimensional picture for a long time, and they may not dare to pass here next time. Because of this, many blind people are afraid to take the blind road because of the obstacles on the blind road.

hotline

Which department can take care of the blind road?

The blind road is occupied. Is there any department that can manage it?

The reporter called the Shijiazhuang City Management Hotline 12319, and the staff of the urban management department said that this situation needs to be understood by relevant personnel before replying.

Then the reporter called the hotline of Shijiazhuang Mayor 12345, and the staff said that they would report it to the relevant departments and hand over the matter.

sound

Blind roads are the standard of urban civilization.

The blind road is the standard of a city civilization. For everyone who needs to use the blind road, this road is "just needed". However, due to various reasons, there are many obstacles on the blind road, which makes the blind people afraid to take the blind road, and the blind road has become a decoration.

Shi Yunfeng, vice chairman of Hebei Association for the Blind, said that the occupation of blind roads is an old topic, and the state has always attached great importance to the travel of blind people, requiring all urban public roads to have blind roads. However, in real life, many citizens simply don’t have this awareness. It is not uncommon for bicycles, cars and stalls to occupy blind roads. Although they have appealed for many years, they have not been well solved.

"Now it is not only unsafe for disabled people to walk in the blind road, but also dangerous. When they walk, the wire hanging on the blind road cuts their faces, or they rub against other people’s cars and even fall into the sewer when they walk. The blind road not only failed to guide the blind to walk, but became a’ road killer’. " Shi Yunfeng said that there are many irregularities in blind road construction. In some places, blind roads are often laid according to the direction of roads, but the practicality of blind roads is ignored. "Builders don’t use them, users don’t have the right to speak", so that there are manhole covers and stay wires in the middle of blind roads.

"There are currently 79,000 visually disabled people in Shijiazhuang, and the occupation of blind roads and the irregular construction have affected their lives; For the country, it is also a huge waste that blind roads can’t be used when they are built. " Shi Yunfeng called on the relevant departments to effectively deal with this situation, and hoped that blind friends as users could be involved in the design and laying stage of blind roads, so as to effectively make blind roads play its due role.

Trump’s "olive branch" was categorically rejected by Iran.

Just before Iran recently held a routine annual military exercise in advance in the Persian Gulf, Trump, who recently sent Iran a "capital tweet" implying the use of force, unexpectedly said that he was ready to meet with Iranian leaders at any time without preconditions: "I am willing to meet, especially when I may face problems such as war, death and famine. There is nothing wrong with meeting. " "If they (Iran) want to, I am ready to meet them at any time." "There is no precondition. If they want to meet, I will. " Trump’s bizarre "olive branch" was not only categorically rejected by Iranian conservatives and moderates, but also failed to change Iran’s Persian Gulf military exercises as scheduled, and was criticized by the media at home and abroad.

Since Trump announced his withdrawal from the Iranian nuclear deal on May 8 this year, the diplomatic game and public criticism between the United States and Iran have never stopped. At present, the international community, especially international public opinion, is doubly concerned about whether the game between the United States and Iraq is developing in the direction of opening peace talks or evolving in the direction of opening war? Opening peace talks is undoubtedly big news, and opening war is even bigger news. This is undoubtedly another unpredictable suspense that Trump has created for the world. In my opinion, in the short term, there is no possibility for the United States and Iraq to start negotiations, let alone war. The two sides are still in the stage of diplomatic game and public opinion attack and defense between pressure and anti-pressure, sanctions and anti-sanctions.

Trump’s diplomatic "soap opera" was embarrassed.

Trump’s casual attitude is not serious, and it is naturally difficult to cause serious treatment and response from Iran. Trump’s loose talk shows that the United States and Iraq can hold unconditional negotiations, which is a manifestation of his capricious and consistent style. Just a few hours before Trump’s speech, US Secretary of State Pompeo also said that the United States and Iran would never hold unconditional talks, and Pompeo was nicknamed "the mouse in the maze" by the media.

Although Trump’s diplomacy is unpredictable, it has also formed a certain "diplomatic routine" on many crisis issues: first, it issued extreme threats, then changed its position, held talks, and finally announced its victory. The most typical case is Trump’s North Korean diplomacy. However, the Iranian nuclear issue is not only fundamentally different from the DPRK nuclear issue, but also Iran’s complicated bureaucratic system, especially the dual structure of conservative and reform forces, and the constraints of religious leaders on the president are very different from North Korea’s power structure, and the geopolitical environment in which the two hot issues are located is also very different. What’s more, the US-DPRK summit was realized under the pressure and communication of Trump for eight months after he took office.

Therefore, Trump’s loose talk about holding US-Iran talks was also accused by the media as a "diplomatic soap opera", and Iran, which has been engaged in diplomacy on the Iranian nuclear issue for 15 years since 2003, naturally will not make a positive response at will. The prospect that it is difficult for the United States and Iran to hold negotiations in the short term is just as Gerald Blank, an expert at the Carnegie Endowment for International Peace in the United States, said: "Iran’s domestic political structure is much more complicated than that in the northern part of the peninsula, and it is not interested in diplomacy with the United States, especially after Trump asked the United States to withdraw from the multinational agreement known as the Joint Comprehensive Action Plan." "At present, if anyone in the Iranian government tries to contact Trump, they are severely criticized by others."

The reaction made by Iran also proves this point. Motahari, deputy speaker of the Iranian parliament, pointed out: "After Trump made an arrogant talk to Iran, negotiation is impossible. This is an insult. " Iranian Interior Minister Fazley said: "The United States cannot be trusted. How can people trust after the United States is arrogant and unilaterally withdraws from the nuclear agreement? " Arribi, director of the Iranian project of the World Crisis Group, commented that "no Iranian leader will meet with the US president who has repeatedly threatened Iran, attacked the Iranian leadership and violated the nuclear agreement at this time."

"Old hatreds and new foes" make the United States and Iraq not qualified for negotiations.

In essence, Trump’s idea that the United States and Iran can negotiate unconditionally is more of a diplomatic strategy, which not only alleviates the international community’s widespread criticism that the United States unilaterally withdrew from the Iranian nuclear deal, but also shifts the responsibility for regional tensions to Iran. At the same time, it is also a strategy to aggravate Iran’s domestic contradictions and disrupt Iran’s domestic political ecology. However, its arbitrariness and hypocrisy can be described as obvious, and Iran, which has rich diplomatic experience, will naturally not take it.

Of course, the deeper root of the difficulty in holding negotiations between the United States and Iran lies in the serious distrust accumulated by the confrontation between the United States and Iran in the past 40 years since the Islamic Revolution in Iran in 1979. The contradictions between the two sides spread throughout the social system, ideology and practical interests. From the beginning of the Islamic Revolution when the United States broke off diplomatic relations with Iran to the hostage crisis, from the 1980s when the United States supported Iraq to confront Iran in the Iran-Iraq war to the Clinton administration’s containment policy, to the Bush administration’s characterization of Iran as an "axis of evil" and its long-term sanctions against Iraq, and now the Trump administration brazenly withdrew from the hard-won the Iranian nuclear deal and exerted extreme pressure on Iran, it can be said that the old hatred between the United States and Iraq has not been solved, and new hatred has been added.

Therefore, negotiations between the United States and Iran are not realistic at all, just as Mehmetali Jaafari, commander-in-chief of the Islamic Revolutionary Guard Corps, said: "Iranians will not allow government officials to meet with the Great Satan." of course，Contact between the United States and Iran through a third party is not excluded. Some analysts pointed out that Oman’s foreign minister visited Tehran and Washington one after another last month, which is likely to play an information communication role between the United States and Iran.After Rouhani came to power in 2013, it was Oman that brokered the bridge between Iran and the United States, which finally led to the resumption of US-Iran contacts and Iranian nuclear talks. According to reports, Trump had sent the message of holding bilateral talks to Iran eight times before. However, the United States kept pressing and shouting about the talks. In addition, the Iranian nuclear deal involved China, the European Union and Russia, which made Iran not easily hold bilateral talks with the United States, and even more afraid of falling into the diplomatic trap set by Trump.

Judging from the future trend, the possibility that the United States and Iran will return to negotiations will not be ruled out even if the United States exerts certain pressure on Iran and forces Iran to compromise in some areas of the 12 conditions put forward by the United States (such as Syria and other issues), but this will not happen overnight, and it is difficult for Iran to abandon other parties in the Iranian nuclear deal and negotiate with the United States alone.

The weight of war: the United States and Iraq can’t bear it.

From the perspective of the United States, although Trump has changed the Middle East policy during the Obama era since he took office, he has continued to exert his strength on the three hot issues of Syria, Palestine and Israel, but its essence is still to maximize the benefits with the minimum investment, and its core is to consolidate the alliance with Saudi Arabia and Israel and profit from it by shaping Iran into a regional core threat. However, Trump, who gives priority to the interests of the United States, revives the domestic economy and ensures the victory of the mid-term congressional elections, has no systematic plan to go to war with Iran rashly. This may be one of the specific reasons why Trump recently said that the United States and Iran can negotiate unconditionally. Its purpose is to cool down the situation in the Gulf region, which is becoming more tense in the context of Iran’s recent military exercises.

In essence, the United States should be well aware of the disastrous consequences of going to war with Iran. If it chooses a "preemptive" war to completely overthrow the Iranian regime, it will trigger regional turmoil and even a full-scale war, and will impact the international energy market and the whole world economy. If limited military strikes involving Israeli, Saudi and other allies are chosen, the United States will not be able to change the Iranian regime in a short period of time, and Iran will definitely choose to threaten to block the US military bases in the Strait of Hormuz and intensify the conflicts in Syria, Yemen and other regions in an all-round way, and the forces fostered by Iran in the Middle East will continue to create troubles. Iranian President Rouhani warned that the war between the United States and Iran would be "the mother of all wars", and this is the profound meaning. The strategic depth of Iran and the Persian nationality’s resistance to power will also be feared by the United States, and the lessons of the United States in Iraq and Afghanistan are just around the corner. Therefore, if Trump is still rational, it is unlikely that the United States will choose to launch a war against Iran.

Iran is facing more serious challenges. The contradiction between Iran’s conservatives and reformists has intensified after the United States restarted sanctions, and the people’s livelihood crisis aggravated by a large number of foreign capital fleeing, currency depreciation and soaring prices has made Rouhani face the phenomenon of "second term curse" of the president in Iranian politics (that is, both reformist and conservative presidents will hit a wall in their second term and end up in a bleak way, and hostile factions will come to power in the next presidential election) more serious, while the United States has become Rouhani’s "second term curse". At present, coping with economic difficulties internally and alleviating the economic crisis; Saving the Iranian nuclear deal from the outside world and easing the pressure of U.S. sanctions are the top priority of the Rouhani administration, which makes it not take the initiative to choose war at all. At present, although Iran has held a very high-profile military exercise, Iran will not easily take actions such as blocking the the Strait of Hormuz to aggravate tensions without a comprehensive or limited military strike by the United States.

Based on the above factors, in a certain period of time in the future, the United States and Iran will continue to struggle mainly in the fields of diplomacy, economy and public opinion, supplemented by mutual deterrence in the military field, and even the friction between the two sides in a third-party battlefield such as Syria will not be ruled out, but it is unlikely that the two sides will engage in direct local wars and total wars.

Of course, the United States will hope that Iran’s economic collapse and even regime collapse will be caused by extreme pressure, and Iran’s political and economic difficulties will naturally continue to intensify. However, Iran’s political toughness is much higher than that of Arab countries where regime changes have taken place before. The political system of the Islamic Republic, which combines religious centralization with democratic elections, a relatively complete bureaucratic system, the mutual restriction between the two forces of reform and conservatism, the absolute loyalty of the Islamic Revolutionary Guard Corps, and the regime’s ability to resist pressure for a long time under war and sanctions, are all factors that enable the Iranian regime to maintain its resilience.

Therefore, before the end of the mid-term elections in the United States this year and the deadline set by the United States for the termination of trade relations with Iran (November 4), the relationship between the United States and Iran will remain in a stalemate, and its future development remains to be observed and evaluated.
