On March 18th, the Third Yangtze River Bridge in Wuhu staged a scientific and technological wonder: 200 Chery cars with intelligent driving crossed the bridge at a uniform speed of 40km/h, and the intelligent driving feat of zero human intervention in the whole process opened the prelude to the intelligent strategy conference of "oil, electricity and intelligence in the world". Known by the industry as the "Smart Night", this grand event not only launched the 500/700/900 smart driving, but also crushed the technical strength of the industry with the iterative speed of the algorithm, announcing that Chery officially became the first echelon of smart driving in the world.

[Intergenerational Revolution of Algorithms]

Chery’s intelligent layout presents a clear step-by-step evolution: the end-to-end large model (E2E) mass-produced in 2025 took the lead in breaking the shackles of traditional modularity, and through the direct optimization of perception-decision, the efficiency of the Falcon 500/700 series in anthropomorphic decision-making was significantly improved. What is more worth looking forward to is that Eagle 900 deeply integrates VLA (Visual Action Language Model) with WM, and has dual capabilities of "scene generation+strategy deduction", which can predict complex traffic situations in advance.

"Practice of technical equality"

When the industry focused on the electrified track, Chery opened up a new battlefield with the wisdom of oil and electricity. Falcon Intelligent Driving System innovatively develops a digital twin platform, which overcomes the problem of response delay of traditional fuel vehicle drive-by-wire actuators and shortens the adaptation period of intelligent driving system. This makes such fuel vehicles also have high-speed NOA capability, realizing real technical equality. In the field of Off-Road intelligence, Falcon Intelligent Driving Off-road, the world’s first off-road intelligent driving technology, broke through the perception bottleneck of unpaved roads, and integrated satellite remote sensing data through Xinghai big data platform, which significantly improved the pass rate compared with the traditional off-road auxiliary system.

[Global data closed loop]

Supporting the technological transition is the global data engine built by Chery. The model learning mileage of 20 million kilometers per day forms a complete closed loop of "global acquisition-cloud training-scene simulation". Especially in overseas markets, 4.5 billion kilometers of real intelligent driving data feedback algorithm optimization has successfully solved regional problems such as the passing rate of complex roundabout in Europe and the perceived stability of dusty weather in the Middle East. Relying on China’s first EU dual certification qualification, Chery plans to land in Europe with Falcon 700 in 2026, and knock on the door of the high-end intelligent driving market with the verification data of 1 billion kilometers in the "digital parallel universe".

[Ecological competition pattern]

Facing the high-precision map dependence of NCA of Huawei ADS 2.0 and XNGP of Tucki, Chery chose to make a differentiated breakthrough: the update frequency of weekly algorithm iteration is four times faster than the industry average; Full-power type adaptability, covering the pain points of traditional car enterprise transformation; Breakthrough of off-road scenes, filling the blank market of intelligent driving. This technical layout has been verified on ET in Xingyue-a heterogeneous redundant system with 30 sensors, and the decision-making is highly anthropomorphic in the unprotected left turn scene.

From the intelligent driving along the Yangtze River to the verification of 1 billion kilometers in the digital universe, Chery is reshaping the industrial structure with intergenerational innovation of algorithms. When Falcon 900′ s VLA+WM architecture realizes L3-level automatic driving, this technological leap from end to end will lead China’s intelligent driving to a new era dominated by "world model".

Recently, two successful hedging cases of geological disasters in Ganzhou and Pingxiang, Jiangxi Province in early March were affirmed and praised as typical cases by the Risk Monitoring and Comprehensive Fire Prevention Department of the Emergency Management Department.

The circular pointed out that these are two typical successful hedging cases of village-level initiative, decisive disposal in counties and townships, municipal early warning and forecasting, and provincial forward-looking planning.

Ganxian District, Ganzhou City: 32 people evacuated overnight.

Since March 2, there have been strong lightning and short-term heavy precipitation in Ganxian District of Ganzhou City for several days. At 9: 30 on March 4, Zeng Junbin, the information reporter of disaster risks and hidden dangers in Luotian Village, Shadi Town, found a mountain crack in front of a house where villagers lived in concentration, so he immediately reported it.

"On March 3, there will be the first strong convective weather in our district this year, and all towns and relevant departments should take precautions in advance." Previously, on February 28th, Ganxian Meteorological Bureau produced and sent meteorological information materials to the district party committee, district government and relevant departments. From 12: 00 on March 3, Ganxian Meteorological Bureau issued warning signals of yellow thunder, blue gale and orange hail, which quickly reached more than 6,000 emergency responders and grassroots information workers in the whole region through SMS, WeChat and other channels.

"After receiving the meteorological warning information, we immediately organized village cadres and information reporters to conduct a comprehensive investigation of the risk points of hidden dangers of geological disasters." Ceng Wei Lin, secretary of the Party branch of Luotian Village, said.

At the same time, the Ganxian District Emergency Management Bureau, together with natural resources, meteorology and other departments and the government of Shadi Town, quickly organized experts to rush to the site for investigation, and confirmed that there were cracks more than 50 meters long in the mountain, and there were signs of new cracking and sinking, and landslides might occur at any time, threatening the safety of residents and high-voltage transmission lines under the mountain. The village committee transferred 32 people from 6 households involved in the risk overnight, and set up physical isolation facilities and warning signs in dangerous areas.

"Meteorological early warning information provides an important decision-making basis for us to carry out defense and emergency rescue work in time." Liu Huajun, director of the Flood Control Office of Ganxian District Emergency Management Bureau, said.

Shangli County, Pingxiang City: 17 people successfully avoided danger.

At 12: 35 on March 4, Li Hua, the information reporter of disaster risks and hidden dangers in Fengqiao Village, Chishan Town, Shangli County, Pingxiang City, immediately rushed to 22 groups of geological disasters in Fengqiao Village for inspection after receiving the warning information of strong convective weather.

Li Hua immediately reported the findings in time when he found that the wall of Hu Qingjie’s farmhouse was cracked, the road in front of the house collapsed and the ground showed signs of settlement. "There is a risk of house collapse, which directly threatens the safety of 6 households and 17 people."

Previously, on February 28th, Shangli County Meteorological Bureau predicted through the analysis of meteorological data that the precipitation process was obviously convective from the evening of March 2nd to the 5th, and some towns and villages might experience short-term heavy precipitation, and made meteorological information materials to be submitted to the county party committee, county government, county flood control departments and relevant towns and villages, prompting them to prepare for defense.

"After seeing the meteorological warning information released by the meteorological department in the township work group, I will conduct inspections in the village at the first time." Li Hua said.

After receiving the reported information, the county emergency management bureau and Chishan town government immediately organized cadres to rush to the scene simultaneously and take emergency measures to timely transfer 17 people from 6 households threatened by hedging and properly resettle them.

As of March 5, before the arrival of precipitation, all scheduled transfer personnel were evacuated safely.

"Rapidly increasing traffic" and "getting more money every day" are all gimmicks to reveal the "short video window with goods" scam.

Nowadays, short-sighted band goods are very popular, and many people also have the idea of live broadcast with goods. Some criminal gangs use short video accounts to operate teaching packages, and cutting a video can quickly increase traffic and make more money, laying a scam.

Fictitious traffic success stories trick users into buying high-priced packages.

Xiao Gan of Shenzhen, Guangdong Province fell into the trap. Xiao Gan bought a set meal from a so-called short-sighted band cargo team and successfully opened a window and set up a small shop online. So, can he get the benefits he expects?

Victim Xiao Gan: After buying it back, I found it very difficult to study the course. As long as I bought their more advanced package, I didn’t need to operate it. Someone would help me to run this account, send videos and run my window. I thought at that time that I had paid more than 2,000 yuan, and if I could really reach that income, I could. Then I bought an upgrade package, totaling more than 9000.

However, this so-called short-sighted band cargo team’s promise to Xiao Gan is in great contrast with reality.

Victim Xiao Gan: At the beginning, the account did have a little profit, but not much. Then I asked him, and they gave me a lot of reasons to say that the market was not good.

Xiao Gan, who realized that something was wrong, began to contact the other party to refund the money. However, I didn’t expect the other party to change his previous enthusiasm and refused Xiao Gan’s request very strongly.

Victim Xiao Gan: They said that we signed the contract. If we signed the contract, I was helping you run it, but the effect could not be fully predicted. I thought I should have been cheated, so I called the police for help.

Xu Maofu, a policeman of the Criminal Police Brigade of shenzhen public Longhua Branch: These effects promised by them in the contract have not been realized at all so far, and the marketing means are in line with the situation of fraud.

The investigation shows that this group has great suspicion of fraud, and the main criminal of the gang is Zhong. So what is the actual operation of this gang? After investigation by the police, they found that the company was located in an office building in Longhua District, Shenzhen, and the division of labor among gang members was very clear.

Xu Maofu, a policeman of the Criminal Police Brigade of shenzhen public Longhua Branch: One is the sales department, the other is the operation department, the other is the after-sales department, and the last is the teaching department, which is composed of these four departments. Sales is responsible for attracting customers, and the operation is to help these victims run his online shop, but in fact they don’t know how to operate, so the company doesn’t need many people in this area, mainly in the sales department. Their employees go to work like normal employees. You can’t tell from the appearance that this is a fraud company.

After grasping the conclusive evidence, the police handling the case decided to arrest the criminal gang.

Xu Maofu, a policeman of the Criminal Police Brigade of Longhua Branch of shenzhen public: On July 20th, a net-closing operation was launched, and 45 people were arrested in total. At present, the funds involved in the case have been frozen to more than 3 million yuan.

After the suspect arrived, the police decided that this was a new type of fraud case. However, the criminal suspect’s fraud method is very similar to the online shop fraud that occurred frequently many years ago, and it is a brand-new deformation of online shop fraud.

Chen Zhuowei, a policeman of the Criminal Police Brigade of shenzhen public Longhua Branch: In the drainage stage, they will promote their company on some short video platforms, so that some people can watch these short videos and think that this company is very powerful.

After the victims pay the first sum of money, the suspects will induce these victims to continue to invest.

Xu Maofu, a policeman of the Criminal Police Brigade of Longhua Branch of shenzhen public: The initial amount is more than 2,000, and it can be upgraded to 9,800 later, and the highest one can be upgraded to the flagship version of 26,800 yuan. They will say that you have invested more than 2,000 yuan at present, and how many fans you have, and then a video broadcast may also exceed 10,000. He said that only when you invest more money can you achieve better operational results. Some victims often hold on to it. Since they have invested some money and hope to make greater profits, they think it is better to gamble again.

However, no matter how invested, the goods in the victim’s short video window can never reach the sales volume advocated by the criminal suspect.

Xu Maofu, a policeman of the Criminal Police Brigade of Longhua Branch of shenzhen public: When the victim felt cheated, he expressed strong dissatisfaction, and even when he wanted to call the police to defend his rights, they were forced to find their own employees to buy his products for the corresponding victims and make some sales, and then asked the company to make some fake fans and make some broadcasts to stabilize the victim.

At present, the suspect involved in the case has been criminally detained by the public security organs according to law, and the case is under further investigation. The police reminded that we must be vigilant about online projects that promise high returns and get rich quickly.

Autumn is a season of moderate temperature and abundant food in a year.

There is a folk saying that snake meat in autumn is more tender and helps to enhance physical strength and immunity. howeverGuangzhou Forestry and Landscape Bureau recently published "It is a rumor that snakes can be eaten! ",responded that:

Recently,There is a rumor from the media that "you can eat snakes from March 1 ST" There are also a number of self-media promotion, processing and sales of dishes with snakes as ingredients, which have attracted the attention of some catering enterprises and citizens, and they have called the wildlife protection department to ask: Can snakes be eaten?

Guangzhou Forestry and Landscape Bureau reminded that,Snakes are not edible!

Whether it’s wild snakes or farmed snakes, They have not been listed in the National Catalogue of Genetic Resources of Livestock and Poultry (2021 Edition) (referred to as the Catalogue), so all business units are not allowed to use snakes as ingredients to process meals.

However, the reporter found that,

People still spread on social platforms.

The message "You can eat snakes this autumn".

So what is the situation in Guangzhou?

Are there any restaurants that still serve snake meat and game?

When the reporter made an unannounced visit ↓

The network still spreads snake-eating information

Some well-known restaurants have recently heard of "closing their hands"

The reporter noticed that since the beginning of this year, some self-media bloggers have recommended restaurants in Guangzhou and surrounding Shunde from time to time on the short video platform to attract diners to taste snake dishes. When autumn comes, some videos are accompanied by slogans such as "autumn wind is the best time to eat game" and "cooking snake family".

Recommend the copywriting of snake meat restaurant on the Internet.

At the same time, the reporter found that there are many restaurants serving snake products in Guangzhou, and these restaurants have a certain popularity among local diners. Among them, there are many recommended copybooks related to a restaurant located in Machang Road, Tianhe. The reporter found that,Although some of the manuscripts were referred to by names such as "big eel", "rongeel" and "water eel", on October 16th, some people still shared their experience in eating snake food.

In addition, the store also launched the package group purchase links of "Classic Dragon and Phoenix Turtle Pot" and "Big Monopterus albus Sanpinhuang". As of October 20th, the above two packages can still be purchased. However, when the reporter called the restaurant to ask if the set meal was sold normally,The staff of the restaurant said that there were no snakes to make in recent days, and they could directly apply for a refund if they bought a set meal.

The reporter’s investigation found that some restaurants have sold snake meat in the past, and there are still relevant dishes and comments in the menu column on the platform. However, when the reporter called for consultation, the other party said: "It is not clear whether the policy allows eating snake meat, so we will not provide it first."

Behind refusing game

Snakes can still be eaten in restaurants.

Then, in the case that many restaurants selling snake meat have "closed their hands", are there any restaurants still selling snake food?

The reporter contacted a restaurant named "Eternal Jibei Water Snake Porridge" near Longmei Paifang in Panyu District through the ordering platform. The waiter of the restaurant said on the phone that he could serve all kinds of snake food, including all kinds of "game". In the restaurant’s recommendation menu,There are many ways to choose from just "snake food", such as ginger oil, salt and pepper, delicious food and spicy food.

In order to understand the situation in depth, the reporter came to the store for an unannounced visit on October 19. When approaching the store, the reporter found that the signboard at the door of the store was suspected of removing sensitive words such as "snake". Not only that, there is a poster on the glass on the left side of the store.It reads the slogan "Protect wild animals and refuse game", and the menu is clearly marked "No taking pictures".

It is suspected that some words have been removed from the signboard of the restaurant.

When further questioning the clerk, the reporter got a clear answer.Snakes can still be eaten in the store. "Yes, for example, in the case of’ Water Law’, if you don’t invoice 190 yuan per catty, it will cost you 10 yuan per catty." The reporter learned that,"Water law" usually refers to the squirrel snake, which is one of the "three protected animals" in China. In addition, the waiter also said that there are many other snakes in the store.Including "poisonous snakes", but did not disclose the specific source channels of snakes.

Expert: Snakes of unknown origin are at risk of spreading diseases.

There are food safety hazards.

Why are there still restaurants that can get ingredients and sell them when snakes are banned? In this regard, Hu Huijian, a researcher and doctoral supervisor at the Institute of Zoology, Guangdong Academy of Sciences, gave an answer in an interview.

According to Hu Huijian, as early as 2020, some southern provinces, including Guangdong, had successfully cultivated a variety of snakes, such as the squirrel snake, the Zhoushan cobra, and the silver ring snake, with relatively high output. At that time, most of the snakes sold in the market were artificially cultivated individuals. "Everyone is eating snakes, and the capture of individuals in the wild is relatively less, which is also a protection for wild snake resources." Hu Huijian said.

"From a legal point of view,It is illegal to process and sell snakes as food. However, snake farming for medicinal and leather materials has not been banned. Hu Huijian said,At present, the source of snake ingredients in some restaurants may come from snake farms used for medicine and leather goods. At the same time, due to the maturity of breeding technology, some farmers may raise snakes privately without filing and registration. He also pointed out that due to the reduction of breeding scale, snakes circulating in the market may also be wild individuals who are illegally hunted.

Hu Huijian told reporters that the source of snakes sold in restaurants is unknown at present, and from the perspective of food safety, it is also highly recommended for the public to eat. "Because of the lack of official supervision, inspection and quarantine,After eating, there is a high risk of infection with diseases and parasites. At this stage, not eating snakes of unknown origin is also responsible for your health. "

Influenza diagnosis and treatment plan

(2018 revision)

Influenza (hereinafter referred to as influenza) is an acute respiratory infectious disease caused by influenza virus, which breaks out and spreads all over the world.

The onset of influenza is acute, although most of them are self-limited, but some of them can develop into severe influenza due to complications such as pneumonia, and a few severe cases progress rapidly and may die due to acute respiratory distress syndrome (ARDS) and/or multiple organ failure. Severe influenza mainly occurs in high-risk groups such as the elderly, young children, pregnant women or those with chronic basic diseases, and can also occur in the general population.

The results of previous influenza surveillance in China show that China is about to enter the influenza epidemic season. In order to further standardize and strengthen the clinical management of influenza, reduce the occurrence of severe influenza and reduce the mortality rate, this diagnosis and treatment plan is formulated on the basis of the Influenza Diagnosis and Treatment Plan (2018 Edition), combined with recent research results at home and abroad and previous experience in influenza diagnosis and treatment in China.

I. Etiology

Influenza virus belongs to orthomyxoviridae and belongs to RNA virus. According to nuclear protein and matrix protein, it can be divided into four types: A, B, C and D.

At present, people are mainly infected with H1N1 and H3N2 subtypes of influenza A virus and Victoria and Yamagata strains of influenza B virus.

Influenza virus is sensitive to common disinfectants such as ethanol, iodophor and tincture of iodine. Sensitive to ultraviolet rays and heat, it can be inactivated at 56℃ for 30 minutes.

Second, epidemiology

(1) the source of infection. Influenza patients and recessive infected people are the main sources of influenza infection. It is contagious from the end of latent period to the acute period. Viruses generally detoxify in human respiratory secretions for 3-6 days, and children and patients with impaired immune function can detoxify for more than 1 week.

(2) means of transmission. Influenza is mainly spread by droplets such as sneezing and coughing, and is directly or indirectly infected by mucous membranes such as mouth, nose and eyes. Contact with items contaminated by viruses can also be infected through the above channels.

(3) Susceptible population. People are generally susceptible. Vaccination with influenza vaccine can effectively prevent influenza virus infection of corresponding subtypes.

(4) High-risk groups of severe cases. The following people infected with influenza virus are more likely to develop into severe cases, so they should be given great attention, treated with antiviral drugs as soon as possible, and tested for influenza virus nucleic acid and other necessary examinations.

1. Children under 5 years old (children under 2 years old are more likely to have serious complications);

2. Older people over 65 years old;

3. Those who are accompanied by the following diseases or conditions: chronic respiratory diseases, cardiovascular diseases (except hypertension), nephropathy, liver diseases, hematological diseases, nervous system and neuromuscular diseases, metabolic and endocrine system diseases, and immunosuppression (including immunosuppression caused by immunosuppressants or HIV infection);

4. Obese people [body mass index (BMI) is greater than 30, BMI= weight (kg)/ height (m) 2];

5. Pregnant and perinatal women.

Third, the pathogenesis and pathology

(1) Pathogenesis. Influenza A and B viruses initiate infection by binding HA to the surface of respiratory epithelial cells containing sialic acid receptors. Influenza virus enters cells through endocytosis, and the virus genome is transcribed and replicated in the nucleus. A large number of new progeny virus particles were replicated, which spread through respiratory mucosa and infected other cells. After influenza virus infects human body, it can induce cytokine storm, lead to systemic inflammatory reaction, ARDS, shock and multiple organ failure, and children may have acute necrotizing encephalopathy.

(2) Pathological changes. Pathological changes are mainly manifested as cluster shedding of ciliated epithelial cells in respiratory tract, metaplasia of epithelial cells, congestion of mucosal cells in lamina propria, edema with monocyte infiltration and other pathological changes. Diffuse alveolar damage can occur in severe pneumonia. Diffuse congestion, edema and necrosis of brain tissue occur when encephalopathy is complicated. Acute necrotizing encephalopathy in children is characterized by symmetrical necrotizing lesions mainly in thalamus, and there is no obvious inflammatory reaction in the local area. Inflammatory reactions such as myocardial cell swelling, interstitial hemorrhage, lymphocyte infiltration and necrosis occur when heart damage is complicated.

Four, clinical manifestations and laboratory examination

The incubation period is usually 1-7 days, mostly 2-4 days.

(1) Clinical manifestations. The main symptoms are fever, headache, myalgia and general malaise. The body temperature can reach 39-40℃, and there may be chills and chills, accompanied by systemic symptoms such as sore muscles and joints, fatigue, loss of appetite, and often sore throat, dry cough, nasal congestion, runny nose and post-sternal discomfort. Facial flushing, conjunctival congestion.

Some of them are characterized by vomiting, abdominal pain and diarrhea, which are common in children infected with influenza B.

Without complications, the course of the disease is self-limited. After 3-4 days of onset, the body temperature gradually subsides and the general symptoms get better, but it usually takes 1-2 weeks for cough and physical recovery.

(2) Complications. Pneumonia is the most common complication of influenza. Other complications include nervous system damage, heart damage, myositis, rhabdomyolysis syndrome and septic shock.

1. Pneumonia

Pneumonia complicated by influenza can be divided into primary influenza virus pneumonia, secondary bacterial pneumonia or mixed pneumonia. The illness worsened 2-4 days after the onset of influenza, or worsened after the recovery of influenza, with high fever, severe cough, purulent sputum, dyspnea, moist rales in the lungs and signs of lung consolidation. The total number of white blood cells and neutrophils in peripheral blood increased significantly, mainly streptococcus pneumoniae, Staphylococcus aureus and Haemophilus influenzae.

2. Nervous system injury

Including encephalitis, meningitis, acute necrotizing encephalopathy, myelitis, Guillain-Barre syndrome, etc.

3. Heart damage

Heart injury is not common, mainly myocarditis and pericarditis. It can be seen that creatine kinase is elevated and ECG is abnormal, and heart failure may occur in severe cases. In addition, the risk of hospitalization and death related to myocardial infarction and ischemic heart disease increased significantly after being infected with influenza virus.

4. Myositis and rhabdomyolysis

The main symptoms are myalgia, myasthenia, renal failure, increased serum creatine kinase and myoglobin, and acute kidney injury.

5. Septic shock

It is characterized by high fever, shock and multiple organ dysfunction.

(3) Laboratory inspection.

1. Peripheral blood routine: the total number of white blood cells is generally not high or low, and the lymphocyte count in severe cases is obviously reduced.

2. Blood biochemistry: hypokalemia occurred in some cases, and creatine kinase, aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase and creatinine increased in a few cases.

3. Etiology related examination:

(1) Detection of virus nucleic acid: Detect influenza virus nucleic acid in respiratory tract samples (throat swab, nose swab, nasopharyngeal or tracheal extract, sputum) by RT-PCR (preferably real-time RT-PCR). The specificity and sensitivity of virus nucleic acid detection are the best, and it can distinguish virus types and subtypes.

(2) Virus antigen detection (rapid diagnostic reagent detection): colloidal gold and immunofluorescence can be used for rapid antigen detection. Because the sensitivity of rapid antigen detection is lower than that of nucleic acid detection, the interpretation of the results of rapid antigen detection should be combined with the patient’s epidemic history and clinical symptoms.

(3) Serological detection: The dynamic detection of IgG antibody level in recovery period is 4 times or more than 4 times higher than that in acute period, which has retrospective diagnostic significance.

(4) Virus isolation and culture: influenza virus was isolated from respiratory tract samples. During the influenza epidemic season, patients with negative rapid antigen diagnosis and immunofluorescence detection of influenza-like cases are advised to isolate the virus.

(4) Imaging findings. Imaging examination of patients complicated with pneumonia showed patchy, ground glass shadow and multilobal exudative lesions in the lung; Those who progress rapidly can develop into diffuse exudative lesions or consolidation in both lungs, and pleural effusion can be seen in some cases.

In children complicated with pneumonia, the patchy shadows in the lungs appear earlier, with multiple and scattered distribution, which is easy to be inflated, and the imaging manifestations change rapidly. When the disease progresses, the lesions expand and fuse, and signs such as pneumothorax and mediastinal emphysema may appear.

V. Diagnosis

The diagnosis is mainly combined with epidemiological history, clinical manifestations and pathogenic examination.

(1) Clinically diagnosed cases. The above-mentioned clinical manifestations of influenza have epidemiological evidence or positive detection of influenza rapid antigen, and other diseases causing influenza-like symptoms are excluded.

(two) to determine the diagnosis of cases. Have the above-mentioned flu clinical manifestations, and have one or more of the following pathogen test results positive:

1. Influenza virus nucleic acid test is positive.

2. The isolation and culture of influenza virus were positive.

3. The level of influenza virus-specific IgG antibody in acute phase and recovery phase increased by 4 times or more.

Six, severe and critical cases

(a) one of the following circumstances is a severe case.

1. Persistent high fever > 3 days, accompanied by severe cough, expectoration of pus, blood sputum, or chest pain;

2. Rapid breathing, dyspnea and cyanosis of the lips;

3. Mental changes: unresponsiveness, lethargy, restlessness, convulsions, etc.

4. Severe vomiting, diarrhea and dehydration;

5. pneumonia;

6. The original underlying diseases are obviously aggravated.

(two) one of the following circumstances is a critical case.

1. Respiratory failure;

2. Acute necrotizing encephalopathy;

3. Septic shock;

4. Multiple organ dysfunction;

5. There are other serious clinical conditions that need to be monitored and treated.

Seven, differential diagnosis

(1) The common cold. The general symptoms of influenza are more serious than the common cold; Tracking the epidemiological history is helpful for identification; The influenza pathogen test of the common cold is negative, or the corresponding evidence of infection pathogen can be found.

(2) Other types of upper respiratory tract infections. Include acute pharyngitis, tonsillitis, rhinitis and sinusitis. Infection and symptoms are mainly confined to the corresponding parts. The local secretion was negative for influenza etiology.

(3) Other lower respiratory tract infections. Influenza with cough symptoms or complicated with tracheobronchitis should be differentiated from acute tracheobronchitis; Pneumonia should be differentiated from other pneumonia, including bacterial pneumonia, chlamydia pneumonia, mycoplasma pneumonia, viral pneumonia, fungal pneumonia and tuberculosis. According to the clinical features, a preliminary judgment can be made, and the diagnosis can be made by pathogenic examination.

Eight, treatment

(1) Basic principles.

1. The clinically diagnosed cases and confirmed cases should be treated in isolation as soon as possible.

2 hospitalization standards (meet one or more of the following standards):

(1) women in the middle and late pregnancy and perinatal period.

(2) The basic diseases are obviously aggravated, such as chronic obstructive pulmonary disease, diabetes, chronic cardiac insufficiency, chronic renal insufficiency and liver cirrhosis.

(3) Meet the diagnostic criteria for severe or severe influenza.

(4) accompanied by organ dysfunction.

3. Non-hospitalized patients are isolated at home and keep the room ventilated. Get enough rest, drink plenty of water, and the diet should be easy to digest and nutritious. Closely observe the changes of the disease, especially children and elderly patients.

4. High-risk groups infected with influenza virus are prone to severe influenza. Early antiviral treatment can alleviate symptoms, reduce complications, shorten the course of disease and reduce mortality.

5. Avoid blind or improper use of antibacterial drugs. Use antibacterial drugs only when there are indications of bacterial infection.

6. Children should avoid aspirin or aspirin-containing drugs and other salicylic acid preparations.

(2) symptomatic treatment. People with high fever can carry out physical cooling or apply antipyretic drugs. Patients with severe cough and expectoration are given antitussive and expectorant drugs. According to the degree of hypoxia, oxygen therapy is carried out in an appropriate way.

(3) antiviral treatment.

1. Timing of anti-influenza virus treatment

Patients with severe or high-risk factors of severe influenza should be given anti-influenza virus treatment as soon as possible, without waiting for virus test results. Antiviral treatment within 48 hours of onset can reduce complications, mortality and hospitalization time. Severe patients with onset time over 48 h can still benefit from antiviral treatment.

Patients who are not severe and have no high risk factors for severe influenza may also consider antiviral treatment within 48 hours after the onset of the disease and after evaluating the risks and benefits.

2. Anti-influenza drugs

Neuraminidase inhibitor (NAI) is effective for influenza A and B..

(1) oseltamivir (capsule/granule): The adult dose is 75mg each time, twice a day. Children aged 1 year and above should be given drugs according to their weight: those weighing less than 15Kg should be given 30mg twice a day; Those who weigh 15 ~ 23 kg are given 45mg twice a day; Those weighing 23 ~ 40kg were given 60mg twice a day; Those who weigh more than 40Kg are given 75mg twice a day. The course of treatment is 5 days, and the course of treatment for severe patients can be extended appropriately. Patients with renal insufficiency should adjust the dose according to renal function.

(2) Zanamivir: suitable for adults and adolescents over 7 years old, usage: twice a day with an interval of 12 hours; 10mg each time (inhaled twice). However, inhalants are not recommended for patients with severe illness or complications.

(3) Paramivir: the dosage for adults is 300-600 mg, 6mg/kg for newborns less than 30 days, 8mg/kg for infants 31-90 days, and 10mg/kg for children aged 91-17 years, once a day for 1-5 days, and the course of treatment for severe cases can be appropriately extended. At present, the clinical application data is limited, and the adverse reactions should be closely observed.

Ion channel M2 blockers amantadine and rimantadine are only effective for influenza A virus, but the current monitoring data show that influenza A virus is resistant to them, so it is not recommended to use them.

(4) Treatment of severe cases.

　 　 [XCAR car original]

　　　　In the last issue of "Engine Oil Lecture Hall (I)", the author explained to you what engine oil is, what is the meaning of engine oil label, and how to distinguish between true and false engine oil. Some friends may ask, saying that there are many doorways in this oil, so how should we choose? Don’t worry, we will continue to talk to you about engine oil in this issue of Engine Oil Lecture Hall (Part II).

　　　　The first part helps everyone to better understand the engine oil through simple introduction and parameter analysis. This article will mainly combine theoretical knowledge with practice to talk about how to choose engine oil. As the so-called "suit the remedy to the case", the reason why we change the oil is the same. If we want to choose the right medicine, we must first understand what the "symptom" is. Everyone knows that engine oil is engine lubricating oil, so its function is only as simple as lubrication? Below, the author will give you a brief introduction to the role of engine oil, which is also convenient for us to "prescribe the right medicine".

1. What is the function of engine oil?

　　　　Engine oil plays an important role in the engine. As long as the engine is running, the engine oil will not stop flowing, and in this flow, it will complete its mission. So what are the main functions of engine oil?

1, lubrication, reduce wear and tear

　　　　Lubricating oil, of course, the first task is lubrication. When the engine is running, high-speed friction will occur on the surfaces of various metal parts. The function of engine oil is to form an oil film between parts through flow, reduce friction resistance and reduce wear, thus prolonging the life of the engine.

2. Cleaning function

　　　　When the engine oil circulates in the engine, it can bring out the carbon deposit, oil stain, sludge and other dirty things produced by the engine, and finally settle in the oil pan to prevent the dirty things from re-entering the engine, thus achieving the cleaning function.

3. Protective effect

　　　　In addition to lubricating the engine, engine oil can also play a protective role through its own "oiliness". For example, engine oil adheres to the surface of metal parts for a long time, so that the metal parts are isolated from the air, which can play a role in rust prevention and oxidation resistance. In addition, the oil adheres to the gap between parts, and the oil film formed can make the parts better sealed and reduce the possibility of leakage.

4. Auxiliary cooling

　　　　With the continuous circulation and flow of the engine in high-speed operation, the engine oil can take out part of the heat in the engine and play an auxiliary cooling role.

5. Buffering effect

　　　　Engine oil can bear part of the impact load transmitted by the bearing, and at the same time, it can also play a certain buffering role for the mutual impact between components.

Second, how should I choose engine oil?

　　　　The above introduces some basic knowledge about engine oil, so what should we do in the process of actually selecting and buying engine oil? The following editor will give you a few tips and introduce how to choose the right engine oil in different categories.

1. The 4S shop told me that this engine oil is special. Is it true?

　　　　First of all, engine oil only has the similar industry standards such as SAE and API mentioned above. Because engine oil manufacturers don’t develop engine oil according to a certain model, there is no such thing as "special vehicle" or "original engine oil", and those products packaged as "original engine oil" are actually produced by engine oil manufacturers, even commercial engine oil. The reason for this phenomenon is just that automobile manufacturers pursue profits. Secondly, as long as you choose the engine oil that meets the vehicle’s use environment, it is appropriate. So don’t be superstitious about those "special engine oil" statements.

2. What kind of engine oil is used in winter?

　　　　Before the cold winter comes, if you happen to need to change the oil, it is recommended that you choose a type with good low temperature fluidity. For example, if you are in the cold northern region, it is recommended that you choose the product with the label of 0W, such as Jinjixing J700U(0W-40/0W-50). If you are in the south where winter is not cold, it is enough to choose products with the label of 5W and 10W. For example, Jinjixing series J500, J600 and J700 all have products with 5W-40 and 5W-30.

3. What kind of engine oil is used in summer?

　　　　Although the temperature is high in summer, it is still a drop in the bucket compared with the high temperature of about 100℃ in the engine, so the selection of engine oil in summer is not too affected by the environment. At present, the viscosity of synthetic engine oil is less affected by temperature, and the engine produced in recent years has newer technology and more precise components, so it doesn’t need too much oil viscosity. In most parts of China, you can only choose SAE 30 products. If your engine is old or worn, it is recommended that you choose SAE 40 products.

4. My car is turbocharged. What kind of engine oil should I use?

　　　　We know that the turbocharged engine with the same displacement is more powerful than the naturally aspirated engine, and its components are more prone to wear, which is beyond doubt. So what kind of oil does a turbocharged engine need? Turbocharged engines need oil with good wear resistance, high temperature resistance, high oil film strength and so on. It is suggested to choose all synthetic engine oil or semi-synthetic engine oil, because synthetic engine oil is the best choice for turbocharged vehicles because of its small temperature change and strong high temperature resistance, which can ensure the oil film strength.

5. synthetic engine oil is so good, is it suitable for all cars?

　　　　Theoretically, all cars can be used in synthetic engine oil. Synthetic engine oil is favored by many car owners because of its good wear resistance and stable stickiness, but are all cars suitable for all synthetic engine oil? The answer is no, for most cars, all synthetic engine oil is a good choice, but its thin oil film is not suitable for old cars with serious wear and tear, or economic models with insufficient engine processing accuracy, because the gap between engine parts of these two types of cars is usually large, and the thin oil film of full synthetic oil can not play a good role in lubrication, resulting in unnecessary wear, resulting in the situation that the anti-wear effect is not as good as that of mineral oil. Therefore, although "flour and rice" is delicious, it may not fill your stomach. Not all cars in synthetic engine oil are suitable.

As early as 2019, when Laotoule had not been rectified, some manufacturers took a fancy to the blank of the electric pickup market and launched an electric pickup truck with a start of 16,800: Kaiyun electric pickup truck. This model belongs to mini electric pickup truck, which is only slightly longer than some four-door mini cars today. Because it does not meet the licensing requirements, Kaiyun electric pickup truck does not need a driver’s license and cannot be licensed.

Limited by the price of 16,800 yuan, the cost of Kaiyun electric pickup truck is very limited. The vehicle is equipped with a motor with only 4 horsepower, and the maximum speed is only 40 km/h. It uses a lead-acid battery pack of 30kWh, with a nominal battery life of 110 km.

In addition, the maximum load weight of Kaiyun electric pickup truck is only 300KG, and the length, width and height of the cargo compartment are 1620x1245x300mm respectively. Although the volume of the cargo compartment is quite large and the vehicle load has reached 300KG, considering that its motor horsepower is only 4 horses, it is estimated that it can’t hold much, and the identity of the old man Le also makes it clear that Yundian pickup truck can only drive in rural areas.

In the electric pickup market, besides Kaiyun electric pickup, there are several other new energy pickup trucks worth recommending. The following are the details of several new energy pickup trucks:

1. Radar RD6

Radar car is a brand of pure electric pickup truck under Geely. The first new energy pickup truck is Radar RD6, which is a medium-sized pickup truck with four doors and five seats. The body length, width and height are 5260x1900x1830mm, the cargo compartment length, width and height are 1525x1450x540mm, and the maximum load weight of the vehicle is 430KG. Compared with other new energy pickup trucks, the load capacity of Radar RD6 is basically the worst.

At present, the battery life of this model is divided into 400/410/550/632 kilometers. The whole system comes standard with fast charging and free home filling piles. It takes only half an hour to charge from 30% to 80% with fast charging, and it takes 7 hours to charge slowly.

2. Great Wall Gun EV

The Great Wall Gun EV is a new energy pickup truck based on the fuel version of the Great Wall Gun, which has a calibrated cruising range of 405 kilometers. It may be because it is equipped with a large-capacity battery pack, and the price of the gun EV is much more expensive than the fuel version of the gun of 9.78-25.98 million.

The body structure of the Great Wall Gun EV is 4 doors and 5 seats, which is divided into standard box version and long box version. The difference between them mainly lies in the length of the cargo compartment and the length of the whole vehicle. The vehicle length of TEU version is 5.3 meters, and the cargo compartment length is 1.5 meters. The vehicle length and cargo compartment length of long box version are 5.6 meters and 1.76 meters respectively, and the maximum load mass is 480KG.

3. General Fukuda EV

Fukuda General EV is also a medium-sized pickup truck based on the fuel version of General Electric, equipped with 88.55kWh lithium iron phosphate battery from Contemporary Amperex Technology Co., Limited, with a calibrated cruising range of 500/536 km. It is one of the pure electric pickup trucks with the longest cruising range on the market at present.

General Fukuda EV is divided into engineering version and ordinary version. The main difference between them is that the cargo compartment of the engineering board is closed, mainly for municipal engineering and other related departments, while the cargo compartment of the ordinary version is open like other pickup trucks.

4. SAIC Chase T90 EV

As a well-known brand of commercial vehicles, SAIC Datong launched a new energy pickup truck T90 EV as early as 2021, positioning it as a four-door and five-seat medium-sized pickup truck with a calibrated cruising range of 535 kilometers, but the maximum speed of the vehicle can only reach 105 km/h.

The cargo compartment size of this model is 1485x1510x530mm, and the maximum load mass is as high as 900KG. It is understood that SAIC Chase T90 EV is mainly oriented to overseas markets and has recently started to land in some European countries and regions.

Generally speaking, new energy pickup trucks have improved in body size, load capacity and cruising range, and are suitable for driving in urban and rural areas. If you want to buy an electric pickup truck, you can choose the model that suits you according to your own needs and budget.

Fourth, safeguard measures

(A) to strengthen organizational leadership, the establishment of collaborative promotion mechanism.

A leading group for coordinating the construction of information and communication infrastructure was established, headed by the deputy governor in charge, and composed of functional departments such as communication management, industry and informatization, development and reform, finance, housing and urban-rural construction, natural resources and ecological environment, and basic telecom operators. The office of the leading group is located in the Provincial Communications Administration, which takes the lead in promoting the project construction, implementing the decision-making matters of the leading group and coordinating the work of various departments. Each state and city shall establish an organization, leadership and coordination mechanism.

(B) increase fiscal and tax support to reduce energy costs.

Give full play to the policy-oriented role, take advantage of the opportunity of the national pilot implementation of universal telecommunications service, strive for central subsidy funds, and increase support for the construction of rural remote areas in our province. Coordinate financial funds to support the construction of 5G base stations and the integrated application of advanced network technologies such as 5G and Internet of Things in digital towns, industrial parks and key industries. Support innovative project financing mode, encourage and guide social investment, and realize investment diversification. Make full use of preferential tax policies, and eligible enterprises can enjoy preferential tax policies such as high-tech enterprises, software enterprises and the development of the western region. Power enterprises should strengthen the power supply network to ensure the stability of power supply. We will implement preferential policies for the good use of electricity, open market access for basic telecommunications enterprises, support enterprises to participate in electricity market transactions, and reduce energy costs.

(3) Simplify the approval process and strengthen resource sharing.

Relevant departments should open up a green channel, handle the examination and approval of land use and electricity use and land title certificate for information and communication infrastructure projects, simplify the examination and approval procedures, and reduce or exempt relevant fees in accordance with regulations; Government agencies, administrative institutions, state-owned enterprises, universities, residential areas, airports, stations, subways, exhibition halls, tourist attractions and other affiliated buildings, as well as street lamps, road signs and other public facilities are free to open. Promote the co-construction and sharing of urban and rural information and communication infrastructure, basic pipelines of special communication networks such as electric power, transportation, water conservancy and education, and various base stations. Promote the co-construction and sharing of power tower resources while ensuring the safe operation of the power grid. Promote the simultaneous supporting information and communication infrastructure for residential areas, subways and other construction projects, and implement the construction of communication pipelines, towers, rooms and other supporting facilities within the building red line. It is forbidden for any institution or individual to obstruct the construction of information and communication facilities without reason or charge unreasonable fees.

(4) Strengthen coordinated promotion and strengthen policy implementation.

The people’s governments of all prefectures and cities should take the construction of information and communication infrastructure as a key task, combine it with the implementation and work promotion of relevant documents such as digital Yunnan, digital countryside, industrial Internet, artificial intelligence, and 5G application, decompose the construction tasks year by year, regularly study relevant matters, and effectively help the construction unit solve the problems of difficult base station location, pipeline laying, and demolition compensation. The Provincial Communications Administration and the Provincial Department of Industry and Information Technology set the annual construction task objectives, and jointly with relevant departments, timely report the implementation of key tasks and supporting policies in the action plan.

(5) Strengthen publicity and training to create a development environment.

Provincial Communications Administration, Provincial Department of Science and Technology, Provincial Department of Ecology and Environment and other departments organized the popularization of electromagnetic radiation from base stations covering all states, cities, counties and districts in the province to eliminate people’s doubts and misunderstandings about base station radiation. Relevant departments should publicize the effectiveness of infrastructure and create a good atmosphere for the construction of information and communication infrastructure.

1905 movie network news In 2019, the most popular country man officially released the theme song "Nezha" MV, which was jointly sung by hip-hop singer GAI and Da Tiao. The theme song specially selected hip-hop style, which is in line with the high-burning Nezha spirit of "not accepting fate" in the film. Recently, in the first batch of advanced viewing activities held in Beijing, the film won the highest score of "five stars for all" and the super-high comment of "close to perfection". The film has both laughter and crying. There are more than 43 times of laughter at the scene, and the scenes related to father-son love make some viewers "cry two tissues". It can be seen that it makes sense that Ne Zha was selected as the first domestic animated film to land in IMAX cinema. The advance screening of the film was opened this weekend and officially released nationwide on July 26.

The strength gives voice to interpret "unwilling fate". So what if the new Nezha was born as a demon

The theme song "Nezha" shows the "teardrop subversion" of the new Nezha from many angles through the protagonist’s monologue: as a "rebel" deeply rooted in the hearts of the people, unlike the audience’s previous cognition, Nezha’s resistance has changed from "killing himself with tears" to "fighting with fate to the end" today, full of juvenile stubbornness. The MV revealed a high-burning bridge section, and Nezha’s head was tilted by the falling sky. Even so, it could give birth to three heads and six arms, and the audience shouted "burning"! This change in Nezha is, to some extent, a change in the beliefs of a generation.

In addition, the MV also shows the story behind Nezha’s "rebellion": Nezha, who looks fearless, tries his best to be recognized by the world. Nezha’s bitter experience captured many tears from the audience, much like every teenager who has experienced or is experiencing rebellion in reality.

At the same time, the unyielding temperament of hip-hop itself is also in line with the theme of "not accepting fate" in the film, just as the lyrics say, "Then let me put all my eggs in one basket and don’t want to spend my days in the dark." For the film itself, GAI was even more excited after watching the movie and said "I like it very much."　

Make with heart, get "full marks" from netizens, control details and create summer masterpieces.

Recently, the film held its first foreign screening in Beijing, which won the audience’s "super high score" real name Amway. One is funny. The movie Ne Zha has a lot of comedy elements, and the plot is full of jokes. According to statistics, the first batch of people laughed at the scene for about 43 times. Secondly, it’s easy to cry. In the film, some fragments about the affection between Li Jing and Nezha’s father and son made many audiences cry. Thirdly, the exquisite interpretation of the theme of "not accepting fate" made the film "ignite" the hearts of many live audiences "burning is not stupid, but cool is really cool", praising its completion, plot, picture, special effects and music, and bringing many "subversive surprises" to the audience.

The production of the film lasted more than three years, and the number of shots in the film was over 5,000. Finally, less than 2,000 shots were "selected" and presented on the big screen, with special effects shots accounting for 80%, in order to show the audience the most perfect "new" Nezha. The production of every shot in the film is excellent. For example, the two parts of Nezha’s "Fire Lotus" and Ao Bing’s "Water Column" revealed in this MV are groundbreaking in animation. It took nearly half a year only in the development stage, and in the formal production stage, the special effects artist repeatedly revised it day and night, which achieved the best effect now.

The film Ne Zha will land in the national cinema on July 26th.

CCTV News:In two months, hundreds of pet dogs died strangely, with the same symptoms and painful death methods, which aroused the vigilance of many pet dog owners in Dalian. They visited repeatedly in areas with high incidence of pet dog poisoning and finally found an important clue.

Many pet dogs have been poisoned (network map)

The key to uncover the truth is this pet dog named Dahuang. Rhubarb is a stray dog adopted by Ms. Wang. On October 24th, Rhubarb played in front of Ms. Wang’s shop as usual.

Ms. Wang, a Dalian citizen:At that time, I was working in the house, and the dog took the medicine there. At that time, the neighbor found it and said that the chicken liver was wrapped in yellow pills.

The experience of rhubarb quickly spread among pets, and everyone quickly rushed to the scene to find clues. Finally, they found a surveillance camera of a lottery station on the side of the road, and this camera just recorded the whole process.

Ms. Li, a citizen of Dalian:Now the suspect appears, with a cigarette in his left hand and something in his right hand. You see, he threw something in this position, and then he turned to see if the dog would eat it. He specially waited for the rhubarb to eat what he threw, and he stayed here for 15 seconds to wait for the rhubarb to eat it.

The owner of the lottery shop next to him found that what Rhubarb ate was very suspicious. In association with the recent pet dog poisoning incidents, the lottery shop owner took out what Rhubarb had in his mouth. Two hours later, rhubarb showed symptoms of shortness of breath. This shows that there is something wrong with the yellow tablets taken by rhubarb.

Veterinarian Zhao Yingzhi:Through these cases, our experience in treatment and some information we checked, we suspect that it is an anti-tuberculosis drug.

Reporter:Is this medicine for people or dogs?

Veterinarians:For human use, anti-tuberculosis drugs, because there is no enzyme to resist this drug in dogs, so as long as they eat a little, they will be poisoned.

Fortunately, rhubarb didn’t eat much, but it finally survived after emergency rescue. The experience of rhubarb and the surveillance video confirmed the suspicion of pet dog owners for the first time. It is true that some people deliberately poisoned and killed dogs, and the poisons were carefully selected.

Veterinarian Zhao Yingzhi:There is no specific medicine, and it is recorded in the data that vitamin B6 is injected in large quantities, but the clinical effect is not particularly obvious through us.

The reporter learned that on August 8 this year, there was an article on the Internet that introduced the use of this drug to kill cats and dogs. Although this article was later reported and deleted by animal protection groups, the methods introduced in the article still spread. What is more serious is that this medicine is not only harmful to pets, but also a threat to people, especially children.

Veterinarian Zhao Yingzhi:Adults may not have a big problem, but if they are children, they will definitely have problems. Because children are small in weight, taking one tablet of this medicine may cause problems. This medicine should be a prescription drug.

At present, the police in Dalian have accepted the reports of pet dog owners. It is understood that the police have merged several poisoning cases and the case is currently under investigation.
