　　How much does the kidney work every day?

　　Chen Min, chief physician of Department of Nephrology, Peking University First Hospital, and deputy director of Peking University Institute of Nephrology: The human body has two kidneys, which are located on both sides of the spine and are about the size of a fist. The "blood filtration project" needs 1.7 million to 2.4 million nephrons. Nephron consists of renal corpuscle and renal tubule, and renal corpuscle includes glomerulus and renal capsule. During the day and night, human blood has to be sieved by the kidney for 40~50 times to ensure that the waste produced by metabolism is excreted in time, and the workload is very heavy.

　　The kidney filters about 1.2 liters of blood per minute, accounting for about 24% of the cardiac output. When the blood enters the kidney, the glomerulus filters out substances such as water in the plasma; The filtered substances enter the renal capsule to form protourine, but useful components such as protein, amino acids and sugar remain. After the renal tubule "receives" the original urine, it reabsorbs the useful components, and at the same time discharges the hydrogen ions and ammonia ions that are not needed by the human body to form urine. In this process, nephron maintains the balance of water and electrolyte.

　　In addition to these, the kidney also participates in endocrine regulation, which can release a variety of hormones, such as renin, prostaglandin and erythropoietin, which can help regulate blood pressure, promote the metabolism of active vitamin D, maintain normal bone metabolism and regulate the production of red blood cells.

　　Do four things well to prevent renal failure

　　Chen Min, chief physician of Department of Nephrology, Peking University First Hospital, and deputy director of Peking University Institute of Nephrology: The onset of renal diseases is hidden and difficult to detect. If early detection and early intervention can significantly reduce the complications of patients and significantly improve the survival rate. Patients with diabetes and hypertension are the most high-risk groups of renal diseases. In addition to actively controlling blood sugar and blood pressure, such people need to pay attention to renal function regularly and regularly detect urinary protein levels and serum creatinine levels. Even healthy people should do the following to care for delicate kidneys.

　　Don’t overeat. Eating too much food at one time will not only increase the burden on the digestive system in a short time, but also produce too much metabolic waste and increase the burden on the kidneys. Long-term overeating can also induce hypertension, diabetes, etc., which will lead to secondary nephropathy. It is suggested to eat some fresh fruits and vegetables such as apples properly, which is beneficial to kidney health.

　　Avoid repeated dehydration. Repeated dehydration caused by high temperature environment is related to the increased risk of chronic renal damage. During dehydration, the secretion of angiotensin and antidiuretic hormone increases, renal blood vessels contract and urine is concentrated. If you don’t replenish water in time, dehydration will be serious and blood volume will be insufficient, which will lead to kidney hypoxia and blood flow reduction, and eventually lead to kidney damage.

　　Pay attention to the urine situation. The most intuitive manifestation of kidney problems is urine changes, such as obvious deepening of color, obvious foam and sudden increase of nocturia. In these cases, you should seek medical attention in time, especially those who are accompanied by obvious weight gain and edema, and are likely to have kidney disease.

　　Pay attention to regular physical examination. People aged 45 and above have to undergo physical examination every year. Those who have a family history of kidney disease, or have a history of diabetes, hypertension, proteinuria and gout, and often take antibiotics and nephrotoxic Chinese medicines, it is best to check once every six months to be alert to renal failure.

　　Soaking feet at nine o’clock in the evening is the best way to protect the kidney.

　　Jiang Haitao, Deputy Chief Physician, Department of Cardiology, Second Affiliated Hospital of Tianjin University of Traditional Chinese Medicine: It is most appropriate to soak your feet in warm water from 9: 00 pm to 11: 00 pm, which can attract our spirit to the lower limbs. Spirit plays a leading role in qi and blood, and qi and blood will descend if you concentrate on it. For some mental workers, it is very useful for the spirit of qi and blood to descend, because after thinking about the problem for a day, the spirit is concentrated on it, and the brain is more excited, so it is more difficult to fall asleep at night. After soaking feet in warm water, the spirit and qi and blood are easier to return, that is, to return to their base camp, and the kidney dominates the storage of essence, so it is the kidney that is replenished after collection.

　　The kidney meridian of human body starts from the first step. After soaking feet in warm water, it plays a warming role and is a benign stimulus to the kidney meridian, which will naturally play a good role in the kidney. Therefore, although no measures have been taken for the kidney, the meridian can also play a role in tonifying the kidney.

　　It should be noted that the water temperature of soaking feet must be moderate, not too hot or too cold. If the water temperature is too hot, it will not help the kidney to collect, but will make people more excited, thus increasing the consumption of kidney essence; If the water is too cold and cold, the meridians will be blocked, and the cold will enter the abdomen along the meridians, and its harm is self-evident.

　　These two conditions can cause acute renal failure.

　　1. excessive exercise. Men Wenjin, Deputy Chief Physician, Department of Nephrology, beijing jishuitan hospital: Excessive exercise may lead to acute renal failure. This is because sudden strenuous exercise is likely to cause muscle injury, which will lead to rhabdomyolysis, and then lead to the increase of myoglobin. Myosin itself will also be decomposed into nephrotoxic components in the body, which will cause further damage to renal tubules and lead to acute renal failure.

　　The common causes of soy sauce color are rhabdomyolysis and urinary system infection. It is normal to cause muscle damage during exercise, but excessive exercise causes rhabdomyolysis, myoglobin in cells enters the blood, and urine will show an abnormal dark brown color. Myoglobin is dissolved too much, which can not be discharged quickly, causing blockage in the kidney, which will lead to acute renal failure.

　　2. High voltage electric shock. Dr. Wang Bo, Emergency Department of Changping District Hospital, Beijing: High-voltage electric injuries often burn large areas of muscles, even involving bones, with large fluid loss, which is more prone to shock than general thermal burns. In addition, a large amount of hemoglobin and myoglobin are released, resulting in severe hemoglobinuria and myoglobinuria, which will lead to acute renal failure. Severe acute renal failure often requires hemodialysis according to the condition.

　　Eight signals indicate that the kidney is ill.

　　Lun Lide, Director of Nephrology Department of Air Force General Hospital: 1. Eyelid or lower limb edema: The kidney will lead to the impairment of water and electrolyte regulation function, causing the increase of water and sodium in the body, and water often accumulates in the loosest tissue or the lowest part of the body, such as eyelids or lower limbs.

　　2. Headache, fatigue, memory loss, poor sleep: Nephropathy is characterized by headache, fatigue, memory loss, poor sleep, etc., mostly caused by hypertension, especially young people who have unexplained blood pressure rise should be alert to kidney diseases.

　　3. Foamed urine: When the protein and urine sugar in urine increase, foamed urine can appear, and there is a fine foam floating on the surface of urine, which is not easy to disappear. You should be alert to proteinuria; If the bubble is large and disappears very quickly, we should be alert to whether the urine sugar rises.

　　4. Changes in urine volume: Normal people’s metabolism is slow after falling asleep, and nocturia is significantly less than that during the day. They should not urinate at night or only pass once, and the nocturia is about 1/4 ~ 1/3 of the total amount in 24 hours. If it is often more than 2 times, nocturia is more than that during the day, which may indicate renal insufficiency.

　　5. Abnormal urine test: If protein or occult blood is positive in routine urine test, it may be asymptomatic proteinuria or asymptomatic hematuria, and urine protein quantification or urine phase microscopy should be done in time.

　　6. Complications with other diseases: Many diseases are prone to kidney damage, such as hypertension, diabetes, gout and polycystic kidney disease. Patients with these diseases should have regular urine tests.

　　7. Anemia: Patients with chronic renal insufficiency above moderate degree often have anemia, fatigue, dizziness, pallor and other symptoms, which is often caused by renal insufficiency leading to decreased secretion of erythropoietin by the kidney. Therefore, in the case of unexplained anemia, besides considering blood system diseases, we should check whether there is kidney disease.

　　8. Loss of appetite: Patients with early uremia often have symptoms such as loss of appetite, nausea and itchy skin. Therefore, patients with these symptoms, especially those with hypertension and anemia, must check their renal function.

　　What needs to be emphasized here is that low back pain is not necessarily kidney disease. Low back pain, which people often say, refers to the pain of the whole back and even the lumbosacral part. There is no sensory nerve distribution in the renal parenchyma, so it is painless, and the pain in the renal area that patients feel is mostly caused by the involvement of renal capsule, ureter and renal pelvis. Some patients with nephritis and nephrotic syndrome only have slight discomfort in the waist and feel sore, and rarely have obvious low back pain.

　　Original title: Why are there many industrial and commercial halls in Chongwai area?

　　The traffic location is convenient for businessmen.

　　According to the Records of Place Names in Chongwen District, there are 154 halls in Old Chongwen District. Although some of them are called fellow country halls, they are actually industry or industrial and commercial halls. There are not many halls that really serve the literati who came to Beijing to take the exam. There are only two halls, Jizhou Trial Hall and Zunhua Trial Hall, which are called trial halls, which are different from other halls.

Linfen Guild Hall, located in Ximaochang Street, is more than 400 years old, and was jointly built by five elements merchants in Linfen, Shanxi.

　　Historically, Shanxi businessmen and Shandong businessmen once dominated Beijing’s economy. Lu ‘an Guild Hall, which was once located in the south of Guangqumen Inner Street Road (now around Anhua Building), was built by Shanxi merchants who engaged in copper, iron, tin and carbon. In the old days, the hardware industry regarded the old gentleman in Taishang as the industry god, so there was an old gentleman hall dedicated to the old gentleman in Taishang in the guild hall. According to historical data, Lu ‘an Guild Hall appeared in the Ming Dynasty, and it grew from small to large, becoming one of the great guilds in Beijing. The "Monument" in the hall in 1920 said: "There was a Shenlu Temple in the old Lu County Hall, and the room outside the courtyard was the tomb of Lu people. For example, offering sacrifices to the meeting, raising the life and stopping the coffin, to the managers of the three gangs of copper, iron and tobacco bags for the county people. " Lu ‘an Guild Hall has the Laojun Temple and the altar for offering sacrifices to the furnace god, because the hardware industry can’t do without smelting furnace, so it is natural to offer sacrifices to the furnace god in the Guild Hall, and the old place name of the Guild Hall was called the furnace holy temple.

　　Shanxi Linfen Guild Hall was established by Shanxi merchants, and Shanxi pigment merchants also built another pigment guild hall in Qingyun Hutong. Pigment is not a concept in the old days, it includes many building materials and daily necessities, and it is a big industry. According to the data of Beijing’s economic history, "the cover of the paint shop is a flower stick, which is more than a foot long. Generally, it is painted in five colors: red, yellow, black, green and blue, decorated with golden flowers and painted with golden paths". This kind of flower stick, also known as the Five Flower Stick, is said to be specially designed to beat the emperor who fainted, and Emperor Yangdi was killed by the Five Flower Stick. Later, the five-flower stick became the symbol of the paint shop. "This kind of cover is always hung, not if other shops hang it early and later, it is intended to be the monarch of Yongzhen."

　　The pigment shop also sells all kinds of waxes, such as Jingyang Yellow Wax and Sichuan White Wax. In the years when there was no electric light, wax was mostly used for urban residents’ lighting, and wax was still a sacrificial object. When they got married, they were called "wedding night", and some scholars "read by candlelight at night", and candles were wax.

　　Linxiang Guild Hall, located in the eastern city of Chongwai, is also related to Shanxi merchants. It was established by Xiangling merchants in Linfen.

　　Cixi Guild Hall was established by a clothing merchant in Cixi, Zhejiang. Garment shops are shops that process, customize and sell garments. In 1923, there were 84 garment shops in Beijing. Shanxi cloth merchants built Jinyi Guild Hall in Xiaojiang Hutong, which was also called "Cloth Guild Hall" because it was built by cloth merchants among Shanxi merchants. According to "Atlas of China Cultural Relics", by the time of the Republic of China, Jinyi Guild Hall was no longer used as a cloth business meeting, but as a place for people from Yicheng, Shanxi Province to reunite in Beijing, and also provided free living services for people who went to Beijing temporarily. In 2011, Jinyi Hall became a part of Liu Laogen Hall.

　　In addition, Fujian paper merchants built Yanshao Guild Hall in Chongwai, while Yuanning Guild Hall was funded by Jiangsu silk merchants.

　　There are many historical reasons for "worshipping foreign countries" industries and industrial and commercial halls. Since the Ming Dynasty, the Grand Canal was cut in two due to the construction of the outer city. "The soil is getting higher and higher, and the boat can’t reach it." The pier of Jishuitan can’t be used anymore, and the terminal pier of the Grand Canal was changed under the Datong Bridge in Dongbianmen, not far from Chongwenmen. In addition to water transport vessels, there are many merchant ships at Datong Bridge Wharf. Merchants often unload ships here. Besides building warehouses and warehouses in Chongwai, they also build industrial and commercial halls. They live in the halls to facilitate business.

　　Since the Ming Dynasty, Chongwenmen has been a very important tax gate. At the end of Qing Dynasty, Prince Su once supervised Chongwenmen’s tax gate. He honored the collected taxes to "Lafayette" and became Cixi’s "rouge money" for her to squander at will. It is said that many of Beijing’s "official residences" were built by her with uncountable rouge money, and she profited a lot from them, which shows that the amount of tariffs and taxes in Chongwenmen is large. After paying taxes, most businessmen live in Chongwai area nearby. They don’t live in chicken feather shops, but prefer private residences. Of course, the most convenient place is the clubhouse built by peers. As a result, it is normal that there are many industrial and commercial and trade halls in Chongwai area.

　　In addition, Chongwai area is the hometown of handicraft industry in history, and all kinds of products have become the source of goods for merchants from all walks of life. Vendors from all over the world bargain and discuss business here. Merchants will build some halls in Chongwai nearby. Although some halls are nominally literati test halls, the imperial examination is held once every three years, and people in the industrial and commercial circles mainly live in them on weekdays. It is natural that there are many industrial and commercial halls in Chongwai Hall.

　　Handicraft developed and business prospered.

　　There are many industrial and commercial halls in Chongwai area, which has a lot to do with the development of handicrafts here. Since the Ming and Qing Dynasties, in addition to many small weaving factories, hosiery factories, hemp rope factories and towel factories, handicrafts such as paper, silk, paper and flower, filigree inlay, cloisonne, ivory carving and feeder have been worshiped abroad, especially around Huashi Street, where they have grown and developed, leaving an unforgettable page.

　　In the 1920s, Beijing Practical Guide made statistics on handicraft workshops and shops in Chongwai area. For example, there are 9 Cui Hua Bureau (making glass jadeite); There are 18 paper flower shops, most of which are in the flower market. There are 13 hemp rope shops, 14 hemp shops and 4 official hemp shops. Chongwenmen was the gate of liquor import and export in history. There was a great demand for wine baskets in that year, and there were as many as 13 shops buying and selling wine baskets in Chongwai area. Interestingly, the shops that buy and sell shoulder poles are also concentrated in the flower market area, with 8 shops. There are 6 feeder shops, and all the mirrors in Beijing are laid in four flower markets, totaling 11.

　　In 2008, Donghuashi Street also made statistics on the shops and workshops in Donghuashi Street in the 1940s, and made the brand "Flower Market Store Directory". There are more than 300 shops recorded in the store directory, mainly Donghuashi Street, excluding Xihuashi Street and the surrounding hutongs, among which there are four paper flower velvet flower shops, and the velvet silk flower Trade Association is also in this street, with one feeder, one silk cutter, one inlay and one enamel shop (workshop) each.

　　The flower market is famous for its flowers, but the flowers here are not flowers, but velvet flowers, silk flower flowers and paper flowers, which are called "Beijing flowers". "Jinghua" was once an indispensable ornament for Beijingers, especially decades ago, middle-aged and elderly women wore bright red velvet flowers on their heads during the Chinese New Year holiday, which was very festive from a distance. Flowers bloom for a short time in the north, and there are seasonal restrictions. People who love beauty decorate the environment with silk flower and put silk flower in a vase to make the room full of spring scenery. As for paper flowers, wreaths are mainly made, and all kinds of flowers have their own uses. The "Jinghua" industry was once very prosperous. According to the "Overview of Industry and Commerce in Beiping", in old Beijing, "there are more than 1,000 flower growers in various markets and homes."

　　The "Jinghua" workshop in the flower market generally does not do all the work, but has a clear division of labor. Some specialize in flowers, some in pistils, some in leaves, and some people or workshops assemble them into finished flowers. "Every morning, thousands of people gather in the flower market to display their products in the market". In addition to retail, larger stalls and "Flower Village" run wholesale and sell "Jinghua" to all parts of the country. In the development of "Jinghua", large-scale merchants, such as flower shops and flower villages, appeared to specialize in the sale of "Jinghua".

　　The technical content of making "Jinghua" is not high. Assembling flowers, stamens and branches is called "saving live". Adults and children can do it, which has solved many people’s employment. In addition to being used as headgear and decorating life, "Jinghua" merchants also provide services for opera artists and act as "outfits". Famous artists such as "Hua Er Liu", "Hua Er Gong" and "Hua Er Jin" have emerged in Beijing Flower Industry. Hemp rope is an indispensable material for Beijing gardeners, so there are many hemp shops in Donghua Market alone. Later, plastic flowers appeared on the stage, and velvet flowers and silk flower plummeted. Coupled with changes in folk customs, not many people wore velvet flowers. "Jinghua" basically doesn’t exist, except for those who make wreaths, and even "Jingyi silk flower Sales Department" has disappeared.

　　In addition to the flower industry, there are many handicrafts in Chongwai that are unique in Beijing, such as filigree mosaic, which is very famous. Filament inlay is a traditional handicraft in China. It processes gold and silver into filaments, shapes them by pushing, pinching and weaving, and engraves patterns on the gold and silver filaments, and then inlays them with beautiful pearls, jade and precious stones. The products inlaid with filigree can be roughly divided into three categories, one is jewelry, the other is display and decoration, and the other is to decorate filigree with some daily necessities. Nowadays, filigree mosaic has become a national intangible cultural heritage.

　　The feeder is also an ancient industry. The grape feeder made in the famous "Grape Factory" is as shiny and shiny as a real grape. The grape feeder is inherited by the "Chang sisters" who originally lived in the flower market. They are Mongolians. In order to keep this craft secret, the Chang sisters never marry. Their deeds are often seen in newspapers. Scholar Deng Tuo once wrote: "The two generations of the Chang family kept the cold, and a hundred years passed down. The purple color of the grapes damages the beauty, and the old dreams are like smoke! "

　　There are many kinds of feeders in old Beijing, except grapes, peaches, fruits, pears, flowers, animals and people can be confused. The feeder takes glass as the main material, and the handicrafts made are colorful, ingenious, lifelike, exquisite, crystal clear and lovely, and are loved by people. In 1964, the feeder company built a building near Longtan Lake, and more than 800 people were engaged in feeder production. Prior to this, feeder artists were all based on families or workshops, distributed in Huashi Street and surrounding alleys, which should be the birthplace of old Beijing feeders in Huashi area.

　　Cloisonne, also known as inlaid enamel, is a kind of ware made of fine copper wire woven into various patterns on a copper tire, and then the enamel glaze is mainly blue and filled in the patterns. Cloisonne craft has a history of 600-700 years in China, and it is called "Cloisonne" because of its high development, exquisite technology and various varieties during the Jingtai period in the Ming Dynasty. Before the Japanese invaders invaded China, cloisonne products in Beijing sold very well, and most of them were exported to Europe, America and Japan, and the Japanese secretly copied them. At the time of its prosperity, there were nearly 100 cloisonne workshops with more than 2,700 employees. Dexingcheng, the second lane in Chongwai, and Da Rui Hall in Tea Hutong are among them. In 1923, there were 15 "Jingtai enamel shops" in Beijing, specializing in cloisonne products. In 1950, Beijing Enamel Factory was built in the south of the Temple of Heaven, and the road next to the factory was named Jingtai Road.

　　Chongwai is known as the hometown of handicrafts and the birthplace of many handicrafts in Beijing. The "Hundred Workshops" established a few years ago confirmed the prosperity of Chongwai handicrafts. Before 1990, there were glassware factories, feeder products factories, art red light factories, craft woodcarving factories, jade factories, theatrical outfitting factories, etc. Many handicraft factories gathered in the same area, which explained the origin of industrial and commercial halls in Chongwai area from the side.

Changjiang Daily Media February 1 (Reporter Wu Ye correspondent Ma Yaoyao) As the Spring Festival approaches, many citizens are busy buying new year’s goods. The doctor reminded that people must pay attention to avoiding the "pit" of allergies when they choose to buy new year’s goods with great joy. The Changjiang Daily reporter learned that the dermatology and ophthalmology clinics in Houhu Campus of central hospital of wuhan recently received many patients with related diseases caused by allergies when buying new year’s goods.

Men itch all over after visiting flower shops.

Mr. Liu, 43, lives in Houhu. On the afternoon of January 31, he and his wife went to the flower and bird market to buy some flowers and green plants to decorate the room and increase the atmosphere of the Spring Festival. After coming to the flower and bird market, Mr. Liu didn’t expect that there were not only many kinds of flowers and plants in the Spring Festival atmosphere, but also various meanings. Every time he went to a flower shop, he had to watch them carefully, listen carefully to the boss’s explanation of breeding methods, and sometimes touch the leaves with his hands and put his nose together to smell the flowers.

Not long after returning home, Mr. Liu suddenly felt itchy. After undressing, he was shocked. He found many erythema and wheal on his back, arms and abdomen. Thinking that it was getting late, he didn’t go to the hospital immediately. He endured until the next day and found that his body was more itchy, many skin were scratched, and diarrhea symptoms appeared. The dermatologist in Houhu District of central hospital of wuhan diagnosed that Mr. Liu had urticaria, and further examination revealed that he was allergic. At present, after drug treatment, Mr. Liu’s symptoms have been significantly improved.

Gao Ying, director of dermatology department, said that before the Spring Festival every year, many patients who were exposed to allergens during the purchase of new year’s goods would be admitted to the clinic, causing acute urticaria. Plants themselves are an important class of allergens. The roots, stems, leaves, flowers and fruits of plants can produce allergens. When they enter the human body through ingestion, inhalation or contact, they will induce allergic diseases under certain conditions.

Director Gao reminded that in winter and spring, we should try our best to avoid going to places where there are many flowers, plants and dust mites. Once citizens find that they have symptoms of urticaria, they should go to regular hospitals for examination in time. acute urticaria patients can be cured by taking drugs regularly for one week. However, chronic urticaria can be formed if it is not treated in time or exposed to allergens continuously. Chronic urticaria is difficult to cure, and symptoms can only be controlled through long-term medication.

The eyes of female white-collar workers are itchy after makeup.

Lily, a 25-year-old female white-collar worker, went to many shopping malls to try on cosmetics in order to wear a heavy makeup at the company’s annual meeting, and also bought some good cosmetics for herself for the New Year. Unexpectedly, the next day, her eyes showed symptoms of tears, photophobia and strange itching, and she was diagnosed with allergic conjunctivitis by eye examination in central hospital of wuhan. By further inquiring about her illness, the doctor who attended the clinic learned that Lily usually loves dressing up and never goes out without makeup. Eyeliner, mascara and Cosmetic Contact Lenses are all essential steps. The doctor judged that she tried a variety of cosmetics at the weekend, so that the use of cosmetics around her eyes led to allergic conjunctivitis.

Xiang Yi, director of ophthalmology, said that allergic conjunctivitis is now caused by improper use of cosmetics, wearing contact lenses and pollen, and its incidence is gradually increasing. The main symptoms of allergic conjunctivitis are tears, photophobia and even itching.

Director Xiang reminded that in recent years, cosmetics have also become the new year’s goods selected by young women who like fashion during the Chinese New Year. Cosmetics themselves contain many chemical synthetic substances, which constantly stimulate the tissues around the eyes, which may cause conjunctival allergy and allergic conjunctivitis. Citizens should stay away from inferior cosmetics. People with allergies should stop immediately after using cosmetics and go to the hospital in time.

　　In order to ensure that critically ill patients can receive timely priority treatment, the reporter learned from the Beijing Municipal Hospital Administration that from May 1, 2019, 20 Beijing-owned hospitals providing emergency services will uniformly implement emergency pre-examination and triage ("emergency classification").

　　According to the former Ministry of Health’s Guide to the Construction and Management of Emergency Department (Trial) (Wei Yi Zheng Fa [2009] No.50) and the national health industry standard "Standardized Process of Hospital Emergency Department" (WS/T390-2012), it is clearly put forward that "emergency departments should formulate and strictly implement triage procedures and triage principles": patients should be divided into "endangered, critical, emergency and non-emergency" 1.

　　Level 1 patients are in critical condition and may be life-threatening at any time, and immediately enter the resuscitation room or rescue room for rescue. Such as cardiac arrest, shock, definite myocardial infarction, status epilepticus, body temperature > 41℃, systolic blood pressure < 70mmHg, blood sugar < 3.33mmol/L, etc.

　　Grade 2 patients are critically ill or rapidly deteriorating and life-threatening, and enter the rescue room for treatment within 10 minutes. Such as severe dyspnea, lethargy, acute stroke, ECG suggesting acute myocardial infarction, active or severe blood loss, etc.

　　Grade 3 patients are in an urgent condition and have potential life threats, and priority is given to diagnosis and treatment before grade 4 non-emergency patients. Such as acute asthma, foreign body inhalation, dysphagia, persistent vomiting, chest and abdominal pain, mild and moderate trauma, mild and moderate bleeding, etc.

　　Grade 4 patients are non-emergency, and the degree of illness is average. According to the guidelines, the waiting time is longer. Such as mild pain without dangerous features, minor abrasions without suture, follow-up visit of patients in stable recovery period, and only issuing medical certificates.

　　How to achieve scientific classification and give consideration to fairness and safety? According to reports, first of all, the emergency departments of all hospitals have arranged experienced personnel to engage in emergency pre-examination and triage, and organized all medical staff related to emergency to conduct special training for all staff; Secondly, the most important basis for grading is the collection of patients’ vital signs by professional instruments, including heart rate, blood pressure, blood oxygen saturation, etc., and the medical staff will combine the patient’s medical history, symptoms and signs to make the final scientific grading and subordinate to the specialty; Third, professionals monitor the condition of patients in the waiting area. For Grade 3 and Grade 4 patients, when waiting in the waiting area, there will be specialized medical personnel to patrol regularly to dynamically evaluate the condition and potential risks of the patients waiting for treatment, and they can be graded again according to the latest evaluation to ensure the safety of patients. If the patient has sudden discomfort, please inform the medical staff in time so as to take corresponding medical care measures in time.

Short video news is changing people’s habit of watching TV news for a long time. The All Media School had previously paid attention to the trend of Washington post’s short video strategy. Today, it once again focuses on methodology. How short video is the most popular?

The Journalist’s Resource website synthesizes many reports and sorts out the essential tips of video editing. To get the best "input-output ratio" of news video production, we need to figure out how long it is most appropriate!

In 2014, a report from the Pew Research Center showed that in the United States, more than 6 out of 10 adults had the habit of watching online videos, and 36% of them chose to watch news videos.

YouTube has more than 1 billion registered users, and the massive user viewing data can most intuitively reflect how long videos are the most popular.

As early as 2012, Pew Research Center began to study the video viewing data on YouTube, and concluded:The most popular video is about 2.1 minutes long.. This video is slightly longer than the local TV news, but shorter than the online evening news collection.

Research institute ComScore found in a report in 2014 that,The average duration of online video (excluding online video advertisements) is about 4.4 minutes.

The Tow Center Digital Journalism Research Center of Columbia University also published a multimedia research report in 2014, compiling the challenges faced by newsrooms, such as how media organizations try to use video as a profitable editing tool.

Although many organizations have published research reports, there is no "absolute standard" for the duration of news videos. This is because, to a great extent, readers’ tastes and standards are constantly changing.Therefore, in the discussion about the length of moving vertical video, there have been various opinions.

However, the latest research from the University of Texas at Austin provides some new perspectives.

The research team published their research results in the professional journal News Research this year, focusing on the quality and length of news videos, trying to find out the characteristics of news videos that attract readers and estimate people’s viewing preferences.

Peter S. Chen, the first author from the University of Texas, published a paper with two co-authors from the University of Southern Mississippi. The core findings are as follows:

1. High-definition image quality and information determine the "first impression"

Although previous studies have proved that if video content can arouse the audience’s interest, they can also tolerate low-quality video images.

But,Readers won’t tolerate pictures that are not informative, poor in texture and have no sense of pleasure.I will not recommend this to others.

2. Don’t ask the source of the video, talk about the hero by length.

It is found that it is most appropriate to keep the video content of a short video at 2.08 minutes. A slightly shorter video is most suitable in 24 seconds.

3. When both image quality and duration are taken into account, image quality takes precedence.

When both quality and length are considered, compared with other videos,People will prefer long and high-definition videos or short and high-definition videos.

4. Quality is paramount, and video editing also needs professional training.

The quality of a news video can affect the audience’s cognition of news organizations, and the longer the video, the deeper the cognitive impression.

In recent years, many editors are required to be able to produce and edit news videos, but they have not received professional training.

"This enables employees who lack professional visual training to post videos online, especially those short videos."And such reckless practices will leave a "bad impression" on readers.

"Just like the paper media dealing with the content crisis, publishing news videos online can only solve the problem of how to attract audiences by overcoming quality problems."The researchers stressed that other components of video still need more research. For example, audio quality and its composition, which is also an important factor for the audience to decide to start or stop watching.

In 2011, a paper in the journal News Research proposed that "the more relaxed the content, the more clicks it can get" by studying YouTube videos. Of course, this is not to deny that traditional news videos can’t gather popularity.

　　Can be called "the first sport in the world", and the culture of football is profound.

　　According to Ge Weikun, a professor in Tsinghua University, this is exactly what China football lacks most.

　　At a speech meeting a few days ago, the old professor who studied physics unexpectedly talked about football and listed a lot of physical knowledge in football, which attracted the attention of many fans for a while.

　　As for China football, he once organized football matches for Chinese and foreign students overseas and led the team to win the championship. He put forward his own suggestions, "What we lack is football culture. Sending dozens of people out like the Jianlibao team can’t solve the problem. "

　　Physics professor studies football? You really have a doorway

　　As a senior physics professor in Tsinghua University, another identity of Ge Weikun is a fan.

　　It seems that the two fields have no intersection, but in fact they are inextricably linked.

　　As early as 2014, together with professors from other schools, he produced an open online video course called "Football and Science", and many people signed up for classes every year.

　　"Up to now, there are about 30,000 people who have participated." He told the The Paper reporter. At present, he is still working on compiling this video course into a book.

　　What made Professor Ge popular on the Internet was his knowledge of physics in football mentioned in a speech a few days ago, which was quite refreshing for fans who were used to tactical analysis.

　　And this knowledge comes from the courses he made before.

　　For example, why can Beckham’s banana ball "turn" the goal in a strange arc? In fact, it is because the rotating sphere is deflected by Magnus’ law in flight.

　　If you want to kick the "elevator ball" that suddenly falls, according to the parabola obtained by physical calculation, you need to make the ball have a high initial speed without rotating.

　　According to Ge Weikun, overseas, scholars have studied the science of football as early as ten years ago.

　　The relationship between the speed and angle of the interceptors in the middle of the interception, the average contact time of each person in a football match, the distance from the penalty to the goal and the goal rate &hellip; &hellip; All kinds of seemingly "unremarkable" data have actually been carefully studied.

　　Theory guides practice, and players can’t be "unlearned"

　　Perhaps in the eyes of fans, these academic football physics studies are not far from the actual playing &mdash; &mdash; After all, no one will measure the angle of the defender when passing the ball and then decide the passing strength.

　　But for players, these studies still have positive significance.

　　"In fact, the main purpose of (these studies) is to give a physical explanation of some phenomena in football, so as to give the technical essentials. When we understand the principle, we can know how to kick. " Ge Weikun said in an interview with The Paper.

　　"For example &lsquo; Elevator ball &rsquo; , it is necessary to (let the ball) not turn, to have a high initial velocity, you need a strong calf strength. Kick &lsquo; Banana ball &rsquo; , it is necessary to touch the ball on the inside of the foot to increase the friction time of the ball. Players are not required to know physics, but this is a scientific method. If the coach saw it, it should be helpful. "

　　In fact, for football, Professor Ge is really not "an armchair strategist".

　　Previously, he studied and taught overseas and lived for more than 20 years. In Britain, he played futsal with the local people, and in the United States and China, he organized a student football team to coach himself.

　　When he was in the United States, he participated in the organization of the first invitational tournament for Chinese and American student teams, and as a result, his team defeated Yale University 1-0 and won the championship.

　　In Ge Weikun’s view, football emphasizes teamwork and is definitely a sport that needs high IQ.

　　As for the cultural training of athletes, there is still room for improvement in China football.

　　"I think we may be right &lsquo; Football should start with dolls &rsquo; This sentence is misunderstood, which does not mean that children should play football all the time. Coach Jin Zhiyang told me that 90% of the young players can’t enter the professional team, and they have no education and a bad future. In the end, parents dare not let their children play football, which leads to worse and worse football in China. "

　　"Japanese coach takeshi okada also said that China’s young players have insufficient cultural education and logical thinking ability. It’s ok to play football, but when you become a coach in the future, it will be insufficient, which will lead to worse teaching. "

　　Football in China is still "unhealthy".

　　Although he is over 70 years old, Ge Weikun is still full of interest in football. He is a professor of physics and a member of Tsinghua University Football Research Center. He can even try his hand on the football field.

　　Like all China fans, he is also looking forward to the rise of football in China, but he has no secret about the problem of football in China.

　　"Football should be a pyramid. It is not enough to look at the spire. Sending dozens of people out like the Jianlibao team can’t solve the problem. (Still depends on) the campus football that is widely carried out now. "

　　In the process of living overseas, he has seen the profundity of local football culture, and China football, as the Italian marshal Cannavaro said, lacks most not money, but football culture and tradition.

　　"For example, in Germany, football has become a part of their culture, just like their music. There are many old people singing very well near the church there. On weekends, I don’t know how many football matches there are. "

　　"In China, football clubs are the names of enterprises, while club names in Britain are place names with strong local awareness. For example, Manchester City, when they were not as powerful as they are now, still has a large number of diehard fans. (Fans) will not only look at the team’s achievements, but also support them even if they are relegated to the second, third and fourth leagues. "

　　Nowadays, many measures have been taken to popularize football culture in China, such as promoting campus football and social football, and increasing the number of stadium facilities. In Ge Weikun’s view, these are all positive signals.

　　However, at the moment, Professor Ge also said, "The commercial flavor of the Super League is too strong, and some of them are not healthy. Football should have a higher value than business. "

　　Recently, the General Secretary of the Supreme Leader attended the forum on cultural inheritance and development and delivered an important speech, stressing the need to adhere to integrity and innovation, to maintain the integrity and spirit of integrity and innovation, to continue the historical context and write contemporary Chinese chapters. China’s excellent traditional culture is the spiritual wealth that shines forever on China’s land. It has both the spiritual code of "where we came from" and the spiritual signpost of "where we are going". We should strengthen our cultural self-confidence, take on the mission and work hard in innovation, and continue to promote cultural prosperity, build a cultural power and build a modern civilization of the Chinese nation at a new historical starting point.

　　Defending is the foundation. Chinese excellent traditional culture is the spiritual lifeline of the Chinese nation and an important source of cultivating socialist core values. From the political ambition of "worrying about the world first, and enjoying the world later" to the patriotic feeling of "striving for the country’s life and death, why not avoid it because of misfortune and happiness", from the lofty righteousness of "wealth can’t be lewd, poverty can’t be moved, and power can’t be bent" to the sacrifice of life for righteousness of "who has never died since ancient times, keeping a fresh heart to shine on history", China’s excellent traditional culture has always inspired Chinese sons and daughters. The tree height thousands of feet has roots, and the water flow Wan Li is active. In today’s situation of profound economic and social development and changes, and diverse values, we should strengthen our historical consciousness, strengthen our cultural self-confidence, learn from classics and traditions, consciously use Bacon, an excellent Chinese traditional culture, to cast souls, enlighten our minds and moisten our hearts, and unite the spiritual strength of all people who work hard and move forward with one heart and one mind.

　　Innovation is the key. The value of culture lies not only in adhering to traditional excellent culture, but also in spreading with the times. Whether it is the popularity of variety shows such as China in Classics and National Treasures or the popularity of adapted dance programs such as Dancing for the Millennium and Only Green, it is the creative transformation and innovative development of Chinese excellent traditional culture, which makes the excellent traditional culture rooted in history shine new light in the new era. Today, facing the new situation at home and abroad, the new situation in the ideological field and the new trend of information technology development, it is more necessary than ever to innovate to inherit and carry forward the excellent Chinese traditional culture. We should rely on the power of the Internet and use market-oriented means to develop more carriers and scenes to spread excellent traditional culture, so that it can enter modern life and blend into the homes of ordinary people, and constantly create new glory of Chinese culture from "broken circle" to "out of circle" and from "alive" to "on fire".

　　Only by adhering to integrity can innovation have a clear position and direction; Only by constantly innovating and being upright can we get the source of vitality and the foundation of power. One of the important reasons why the Chinese nation has stood firm and courageously advanced in the torrent of history is that generations of Chinese sons and daughters have cultivated and developed a unique and profound Chinese culture in the process of integrity and innovation, which has provided a strong spiritual support for the Chinese nation to overcome difficulties and live endlessly. The wisdom and essence of Chinese excellent traditional culture have permeated all aspects of governing the country, from "people first, life first" to "Lucid waters and lush mountains are invaluable assets". Facing the future, we should organically combine upholding and developing Marxism with carrying forward China’s excellent traditional culture, unswervingly follow the road of Socialism with Chinese characteristics, and constantly push the cause of the Party and the country to a new level.

　　Cultural prosperity leads to national prosperity, while strong culture leads to strong nation. Firmly holding the "root" and "soul" of Chinese excellent traditional culture, always rooting in the fertile soil of Chinese culture and constantly absorbing the nourishment of innovative practice, we will surely gather the majestic cultural forces and strive to write a new chapter in building a socialist modern country in an all-round way.

　　CCTV News:In the past few days, many places in the country have ushered in the peak of returning home. According to the data of the smart car networking platform of the State Grid, as of February 5, the charging amount of new energy vehicles in the expressway service area on the platform has increased by more than 60% compared with the same period of last year. With more and more new energy vehicles joining the returning army, the "travel tide" has formed, and the "charging tide" of new energy vehicles has also appeared.

　　The data shows that in the 11 days from January 26th in Spring Festival travel rush to February 5th, the charging amount of new energy vehicles in the expressway service area reached 34,089,100 kWh, and the charging times reached 1,519,400, which were 67.06% and 48.42% higher than that in Spring Festival travel rush in 2023, respectively.

　　According to the platform data, during the Spring Festival travel rush in 2024, the peak period of the whole high-speed busy index reached 30%&mdash; 40%, which shows that among all the stations on the expressway, there are 30%&mdash; 40% of the stations are fully charged. At ordinary times, the charging busy degree of these stations is only about 10%, and the busy degree has doubled or tripled, showing an obvious tidal phenomenon.

　　Emergency charging compartment of mobile charging vehicle should deal with "charging tide"

　　In view of the "charging tide" brought by the "travel tide" of new energy vehicles, during the period of Spring Festival travel rush, many places in China took various measures to solve this problem.

　　It is predicted that during the Spring Festival in 2024, the average daily charging capacity of Jiangsu expressway service area will reach 600,000 kWh, a year-on-year increase of 70%, a record high. In order to alleviate the charging pressure, Taizhou power supply department has reformed 7 service areas and 14 charging stations within its jurisdiction, and equipped mobile charging vehicles. In Qinhu service area on Yanjing Expressway, a 120kW mobile charging vehicle is specially equipped, which can provide uninterrupted charging service for four electric vehicles at the same time.

　　In Pingwang Service Area, Wujiang District, Suzhou City, there are 16 charging parking spaces in the north-south direction. Since Spring Festival travel rush, affected by high-speed tidal phenomenon, eight charging parking spaces on the north side of the service area are basically full every day, but there are vacant parking spaces on the south side. Local staff guided some cars on the side with large traffic flow to the opposite idle service area for charging through the two-way culvert, which effectively improved the bearing capacity of the service area.

　　In Tianjin, in order to reduce the waiting time for new energy vehicle owners to charge on expressways, the local electric power department started the emergency charging cabin in the expressway service area on the one hand, and upgraded the charging facilities of 46 busy high-speed charging stations in advance. After the renovation, the average charging time was shortened by nearly 30%.

　　Scientific layout to ease the expressway "Charging tide"phenomenon

　　China has been speeding up the layout of charging piles, so that electric vehicles can alleviate the "energy-filling anxiety" of expressways. In the future, this phenomenon of "charging tide" is expected to be alleviated with the increasingly intelligent and efficient energy-replenishing network of expressways being gradually woven.

　　According to the data of the Ministry of Transport, at present, there are more than 20,000 charging piles in expressway service areas nationwide, covering nearly 50,000 parking spaces for minibuses. The coverage rate of charging facilities in expressway service areas in Beijing, Liaoning, Jilin, Shanghai, Zhejiang, Hunan and Xinjiang has reached 100%.

　　According to the data of China Electric Vehicle Charging Infrastructure Promotion Alliance, at present, the increment ratio of piles to vehicles is 1:2.5, and the construction of charging infrastructure can basically meet the rapid development of new energy vehicles. Experts say that highway charging piles are usually idle and not enough for holidays. To solve this "tidal" problem, we should not just consider the increment, but also improve the quality to ensure its economy.

　　In Liaoning, for new energy vehicle users, the local high-speed charging travel guide has been issued, so that drivers can check the layout of charging piles in advance, so as to better plan the charging line. At the same time, the local power department also accurately grasps the status of each charging pile, such as pile body, display and charging cable, through the digital platform, and problems can be solved in real time.

In the competition with the same class models, it is worth mentioning in terms of space performance. Let’s take you to appreciate its style.

Let’s take a look at the appearance of the plug-in hybrid of Lingrui. The overall appearance of the plug-in hybrid front of Lingrui is unique and looks more dynamic. Coupled with simple headlights, the visual effect is still good. The car is equipped with LED daytime running lights, automatic opening and closing, adaptive far and near light, delayed closing and so on. Come to the side of the car, the car body size is 4685MM*1935MM*1710MM, the car uses simple lines, and the side circumference gives people a very fashionable and dynamic feeling. With large-sized thick-walled tires, it gives people a very simple feeling. In the design of the rear end, the rear end and the front end echo each other from a distance, and the taillight style is relatively young and individual, creating a good gas field.

In the plug-in hybrid car, the plug-in hybrid interior looks very fashionable and elegant, highlighting the hierarchical effect. The car looks very good outside the steering wheel, and it is made of genuine leather, so it feels good. Take a look at the central control. The car is equipped with a touch-sensitive LCD central control screen with young personality, which makes the interior style impressive and conforms to the mainstream aesthetics. The dashboard and seats are equally eye-catching. The car is equipped with a simple dashboard, and the information is easy to read and clear. The car uses leather seats, which are wide and thick and very comfortable to ride.

The car is equipped with car networking, driving mode selection, remote control key, Bluetooth key, NFC/RFID key, rear wiper, interior atmosphere light and other configurations, which greatly improves the convenience of using the car.

To sum up: SUV has an atmospheric appearance, good spatial performance and high cost performance. I wonder if you are interested in it.
