FAW Toyota has sold 139,800 sharp-release twin engines, with ultra-low fuel consumption and higher practicability.

Since the beginning of this year, Toyota’s products have been updated to the fifth-generation intelligent electric hybrid dual-engine system in order to better cope with the mixed market of involution. At the same time, the new cars launched this year have also been upgraded for intelligent driving, intelligent interconnection and intelligent cockpit.

On August 6th, FAW-Toyota Corolla sharp-release intelligent electric hybrid twin engine also strengthened its strength in these aspects, and its official guide price was 139,800-184,800 yuan. This is the first time that Corolla Ruifang has launched a hybrid version, which will be more competitive than joint venture rivals such as exploring songs and hackers.

The strength of sharp-release dual-engine products has been comprehensively improved.

Corolla sharp-release twin-engine is equipped with the fifth generation intelligent electric hybrid twin-engine system, which consists of a 2.0L naturally aspirated engine, an electric motor and an E-CVT continuously variable gearbox. In the first half of this year, this system has been applied to various models of Toyota. It has been fully optimized in terms of motor, battery and electronic control, and has strengthened its electric drive. It has been completely optimized in terms of acceleration performance, ride comfort and fuel economy.

For example, the fuel consumption per 100 kilometers of Ruifang intelligent electric hybrid twin engine is 4.56L, which is greatly improved compared with the fuel version, and this has become its biggest highlight. This data is competitive with joint ventures or independent products of the same level. From the earlier test drive experience of the vehicle equipped with Toyota’s fifth-generation intelligent electric hybrid dual-engine system, it can be clearly felt that the vehicle’s ride comfort is better and the power output is stronger under the conditions of reducing the weight and volume of the battery and increasing the output power of the high-speed motor. This is because there are more opportunities for the motor to intervene in the high-speed environment, which is also the key reason for improving the fuel economy of the vehicle.

In addition, the sharp-release intelligent electric hybrid dual-engine comes standard with T-Pilot intelligent driving assistance system, Toyota Connect intelligent interconnection and Toyota Space intelligent cockpit, which optimizes some original functions and adds more functions, and comes standard with the whole system, realizing intelligent equal rights and comprehensively improving intelligent strength. For example, in terms of active safety function, the sharp-release intelligent electric hybrid dual-engine can identify vehicles and pedestrians in the visual blind area in advance, and can also assist in braking or even avoid when a collision accident is about to occur.

Ruifang, which was born in the name of Corolla, has the characteristics of comfort, practicality, safety and high quality. In the entry-level joint venture compact SUV market, it is a powerful player, and it is common for the monthly sales to break through 10,000. After the dual-engine model is added, the audience of Sharp will be wider, thus further promoting sales. The SUV with the positioning and price close to that of Sharp Power Smart Electric Hybrid Twin Engine, as well as BYD Song PLUS DM-i and Geely Yinhe L7 in independent brands, the latter are all hot spots in the market, and the voice of independent hybrid is very high at present, so the challenges that Sharp Power Smart Electric Hybrid Twin Engine will face are not small.

All star models challenge five major projects

In this listing conference, FAW Toyota also brought test drive experience activities for its various models. The 2023 Asian Dragon, New Corolla, New RAV4 Rongfang, Smart Electric Hybrid Twin-Engine Crown Lu Fang and Sharp Electric Hybrid Twin-Engine have passed the five challenges, namely, Rapids, Voices of the Future, Braves, Roller Coasters and Space Exploration.

Among them, the 2023 Asian Dragon carried out the challenge of "Rapids", and put a water cup on the roof. Under the linear acceleration, only a few water in the water cup overflowed, and the acceleration stability and body support were sufficient, which was due to its low center of gravity and other characteristics.

The new Corolla, the new RAV4 Rongfang and the sharp-release intelligent electric hybrid twin engines participated in the "Voice of the Future" challenge. After waking up the car system once, they can say all the instructions for controlling air conditioning, windows, music, navigation, etc. in one breath, because these models all support the function of 30-second continuous voice dialogue.

In addition, the new Corolla also participated in the "Brave" challenge project, which responded quickly when identifying obstacles and dummies on the road, and was able to assist users in braking and avoid collision accidents to the greatest extent.

It is worth mentioning that the intelligent hybrid electric twin-engine version of Crown Lu Fang, in the "roller coaster" challenge project simulating cross-country cross-axis sections, has shown excellent driving and control strength under the configuration of E-Four electronic four-wheel drive system and TRAIL one-button escape mode.

MPV Gravia has also ushered in its "space exploration" challenge. For such a big car, parking is a big problem, but fortunately, Gravia is equipped with PVM panoramic monitoring system, PKSB parking auxiliary braking system and other configurations, which can be easily put into storage.

Driven by these models with outstanding product strength, FAW Toyota sold 373,195 vehicles in the first half of this year, up 6% year-on-year. Among them, the cumulative sales volume of Ruifang was 54,039 vehicles, a year-on-year increase of 140%.

Write it at the end

In the first half of the year, FAW Toyota sold 99,895 smart electric hybrid twin-engine vehicles, up 6.3% year-on-year, accounting for 26.8%. At the same time, the proportion of mid-to-high-class vehicles under TNGA-K platform, represented by Asian Dragon, Graveyard and Crown Lu Fang, increased to 46%. These two sets of data show that FAW Toyota is accelerating electrification, embracing new changes, and steadily promoting high-quality development. The launch of sharp-release twin engines is also an important embodiment of FAW Toyota’s new and upward development. (Text | |DAN)

Do not blindly follow the trend! Growth factors can only be injected externally or cause disfigurement.

  At present, the growth factor for external use is safe and effective, and can promote wound healing. However, it should be emphasized that growth factors can only be used for external use, and it is illegal to inject or take orally, which is prohibited by the state.

  Li Gang, Chief Physician, Department of Plastic Surgery and Medical Beauty, Second Hospital of Tianjin Medical University

  Nowadays, on some social media, many bloggers in online celebrity will recommend a filling injection material called "growth factor", saying that as long as it is injected into the depressed part of the face, it can promote the growth of cells in this part, make it become "self-filler" and make the original "collapsed" part full.

  In this regard, Li Gang, chief physician of the Department of Plastic Surgery and Medical Beauty of the Second Hospital of Tianjin Medical University, said that the growth factor for external use is safe and effective at present, which can promote wound healing.

  "However, it needs to be emphasized that growth factors can only be used externally, and it is illegal to inject or take orally, which is prohibited by the state." Li Gang said.

  The use method is limited to external use.

  Earlier, there were many reports that some beauty lovers were injected with growth factors, which caused their chins to grow crazy and their foreheads to bulge, which made people once talk about the discoloration of growth factors.

  "Growth factor is a kind of cytokine, which is a kind of polypeptide substance that regulates cell growth by combining with specific and high affinity cell membrane receptors." Li Gang explained that growth factors will transmit signals to cells through specific receptors on the plasma membrane and act on genes related to cell proliferation, thus affecting cell growth or differentiation. In short, growth factors are substances that can promote cell growth and proliferation.

  The human body secretes a variety of growth factors, which regulate and control the growth, development, metabolism, aging and other life activities of body cells.

  "From a physiological point of view, there are three kinds of growth factors, of which two have cosmetic effects." Li Gang introduced that the first one is epidermal growth factor, which can promote the growth of epidermis and stimulate the division of basal cells, thus repairing damaged epidermis; The second is fibroblast growth factor, which can promote the growth of collagen and help the recovery of dermis. These two kinds have cosmetic effects. The third is vascular endothelial growth factor, which can promote the growth of blood vessels and lymphatic vessels.

  Clinically, growth factor is a regular external drug. After skin injury, whether acute or chronic, it can accelerate the healing of skin wounds after being coated with growth factor. "Skin aging is actually a chronic injury to the skin, which is also the principle that growth factors can be used for beauty. At present, epidermal growth factor and fibroblast growth factor are also widely used in medical skin care. " Li Gang said that growth factors can repair damaged skin (corneal and epidermal damage) and skin after laser surgery. It can regenerate epidermis and help skin form a healthy barrier. This barrier is very powerful, which can improve the skin’s heat preservation, anti-allergic and anti-radiation abilities.

  However, Li Gang emphasized that whether as a medicine or a beauty product, the use of growth factors is limited to external use, and the general use method is daubing or spraying.

  Cells may grow out of order after injection.

  "The growth factor for external use is safe and effective and can be used as a therapeutic drug, but the state has only approved its use as an external drug. If it is illegal to inject or take orally, it is impossible for growth factor injections to appear in regular hospitals." Li Gang said.

  Data show that many patients with disfigurement caused by the use of growth factors are injected with growth factors or drugs containing growth factors. Some people cause abnormal facial growth after injection of growth factors, such as irregular bulges on the skin.

  "After the growth factor is injected into the human body, its role in promoting growth is uncontrollable, which will lead to a disorderly and disorderly growth, which may have a series of adverse effects." Li Gang said.

  First of all, after the growth factor is injected into the human body, it will stimulate the skin cells around the injection site to multiply rapidly, leading to unlimited or abnormal growth of tissues, and the skin will have symptoms such as redness and hardness. The newly grown tissues often exceed the expected size, and may even lead to disfigurement.

  Secondly, once there is a problem, it is very difficult to take out the growth factor. Even if the doctor takes it out, it is difficult to ensure that there is absolutely no residue. "Even if only a little growth factor remains in a certain part, the part can grow wildly." Li Gang said.

  In addition, the injected person may be disfigured by human factors. For example, due to improper injection techniques or operations, growth factors are injected into large blood vessels, causing vascular embolism; Pinhole infection causes skin to fester, forming scars and even keloids.

  "In short, at present, China has not approved any growth factor filling drugs, and drugs containing growth factors are prohibited from being used for tissue filling." Li Gang stressed.

  Growth factors often appear in "vest"

  Although the state explicitly prohibits it, accidents of disfigurement caused by injection of growth factors still often appear in the news.

  "Every once in a while, a so-called ‘ High-tech products ’ These new products are probably just illegal injection fillers ‘ Vest ’ That’s all. ‘ Freeze-dried powder ’ ‘ Growth peptide ’ ‘ Stem cells ’ ‘ Youth element ’ … … These sound ‘ Gaodashang ’ Our products are actually growth factors. " Li Gang reminded that many beauty seekers were injected with these growth factors in "new clothes" without knowing it. Once the injection area was found to be abnormally raised and continued to grow, it is recommended to go to a regular hospital for examination as soon as possible.

  Then, if there is a filling demand, which products can the majority of beauty lovers choose?

  "The most commonly used injection filling is hyaluronic acid (hyaluronic acid). Human skin itself contains a lot of hyaluronic acid, which is a moisturizing factor of the skin. After being injected into the human body, it can expand to 500 to 1000 times. In addition to the characteristics of moisturizing and volume expansion, it also has biological stability, is not easy to transfer and is water-insoluble, which also makes hyaluronic acid a very good tissue filler with high filling efficiency and safety. " Li Gang pointed out that, for example, water needles also contain hyaluronic acid.

  Because injection beauty belongs to micro-plastic surgery, many beauty lovers feel that it has little side effects and quick recovery, so this kind of project is highly sought after. In this regard, Li Gang reminded that even micro-plastic surgery does not mean "no risk, micro-risk". "Micro-plastic ‘ Micro ’ It does mean minor damage, but it doesn’t mean simplicity, but it means subtlety and subtlety of technology. When carrying out these medical beauty projects, beauty lovers need to polish their eyes and find regular medical institutions and qualified professional doctors for micro-plastic surgery, instead of making micro-plastic surgery ‘ Critical plastic surgery ’ 。” He said.

  Relevant experts said that when injecting hyaluronic acid, it is not uncommon for patients to have vascular embolism and nerve injury, and even lead to skin necrosis, even blindness, hemiplegia and death, due to the lack of professional and formal medical education and ignorance of facial anatomy.

  "In recent years, ‘ Yan value economy ’ And ‘ Pleasant consumption ’ With vigorous growth, the medical and beauty industry has mushroomed. Strong demand not only promoted the development of the market, but also gave birth to many industry chaos. In order to avoid ‘ Tread on the pit ’ , the majority of beauty lovers should not blindly follow the trend, and do not want any product ‘ Fire ’ Just try it easily. It is necessary to learn more about medical beauty knowledge and choose a regular hospital or beauty institution for medical beauty operation. " Li Gang stressed again.

Cell Stem Cell: dopaminergic progenitor cells derived from human embryonic stem cells in the treatment of Parkinson’s disease

Original biological world

Typesetting and writing in water

Cell therapy is considered to be very suitable for treating Parkinson’s disease (PD) because its pathogenesis is relatively simple and characterized by localized degeneration of dopaminergic neurons in the substantia nigra compacta of the midbrain. In animal experiments and human experiments, transplanting human fetal ventral midbrain tissue or cells has been proved to help restore motor function.

However, these results are often inconsistent, which highlights the need for improved cell therapy programs to ensure that a sufficient number of well-defined midbrain dopaminergic (mDA) neurons are produced and standardized cell preparation and transplantation procedures are adopted.

Recent technological progress has enabled human pluripotent stem cells (hPSC), such as embryonic stem cells (ESC) and induced pluripotent stem cells (iPSC), to efficiently generate mDA neurons, paving the way for establishing transplantation therapy for Parkinson’s disease based on hPSC. Many studies have shown that when transplanted into animal models of Parkinson’s disease, mDA progenitor cells derived from hPSC are well integrated into the host brain and mature into functional mDA neurons, which significantly improves motor function.

Recently, researchers from Yonsei University School of Medicine published a research paper entitled: preclinical and dose-ranging assessment of HESC-derived dopaminergic prognosticators for a clinical trial on Parkinson’s disease [1].

In this study, high-purity midbrain dopaminergic (mDA) progenitor cells were produced on a large scale from clinical human embryonic stem cells (hESC), and the safety and effectiveness of mDA progenitor cells were verified in vitro and in vivo. MDA progenitor cells improved the disease-related behavior of Parkinson’s disease rat model in a dose-dependent manner. Based on these preclinical research results, the research team obtained the approval of the Korean Ministry of Food and Drug Safety for the phase 1/2a clinical trial of cell therapy for Parkinson’s disease, and started the treatment of 12 patients with Parkinson’s disease.

In May, 2020, researchers at Massachusetts General Hospital reported a groundbreaking study in the New England Journal of Medicine (NEJM) [2]. A Parkinson’s patient who received autologous transplantation of mDA progenitor cells from hiPSC showed stable or improved clinical symptoms 24 months after implantation. Now, this method has been further developed, and the mDA progenitor cells derived from hiPSC and hESC began to enter the early clinical trial stage.

The first step in the clinical application of cell transplantation for Parkinson’s disease is to define the characteristics of cell products comprehensively. It is very important to determine whether cells are produced with clinical grade materials under GMP conditions and whether they meet the expected clinical use standards. Subsequently, preclinical research should produce convincing evidence of curative effect through large-scale animal experiments, and systematically examine long-term safety-related issues, such as toxicity, biological distribution and tumorigenicity. In addition, preclinical research needs to determine the optimal cell dose range for transplantation as a reference for human trials. Most importantly, the whole research design must be meticulous and the results must be evaluated in a fair way. This usually requires cooperation with CRO and extensive discussions with regulators.

This paper describes the process and results of a preclinical study aimed at using midbrain dopaminergic (mDA) neurons derived from human embryonic stem cells (hESC) in human clinical trials to treat Parkinson’s disease.

The cell differentiation method used in this study has been optimized for clinical application to ensure that it meets GMP standards. This optimization method can produce mDA progenitor cells with high purity and low temperature preservation on a large scale, while maintaining strict quality control. A year-long large-scale transplantation study by an independent CRO company using immunocompromised rats showed that the transplanted mDA neurons did not cause tumorigenicity, significant toxicity or ectopic integration outside the injection site. In addition, clinical mDA precursor cells showed therapeutic potential and dosage range, and produced therapeutic effects in toxin-induced semi-Parkinson’s rats. These findings provide the necessary information about the appropriate cell dose for human trials.

Specifically, this paper introduces the method of large-scale extraction of high-purity mDA progenitor cells from clinical grade hESC under strict GMP conditions, and also evaluates the toxicity, biological distribution and tumorigenicity of these cells in immunocompromised rats in facilities conforming to good laboratory practices (GLP). Different doses of mDA progenitor cells were transplanted into the semi-Parkinson’s rat model, and it was observed that there was a significant dose-dependent behavior improvement when the minimum effective dose ranged from 5000 to 10000 mDA progenitor cells. These results provide insights for determining the low cell dose (3.15 million cells) in human clinical trials.

Based on these experimental results, the research team obtained the phase 1/2a clinical trial of cell therapy for Parkinson’s disease approved by the Korean Ministry of Food and Drug Safety, and started the clinical trial of treating patients with Parkinson’s disease.

At 10 o’clock on July 28, the Central Meteorological Observatory continued to issue a typhoon red warning.

  CCTV News:The Central Meteorological Observatory continued to issue a typhoon red warning at 10: 00 on July 28.

  The center of the No.5 typhoon "DOKSURI" this year landed in the coastal area of Jinjiang City, Fujian Province around 9: 55 am today (28th). When it landed, it was weakened from super typhoon level to strong typhoon level. The maximum wind force near the center was 15 (50m/s), and the lowest pressure in the center was 945 hectopascals. At 10 o’clock, its center is located in Jinjiang, Fujian, which is 24.7 degrees north latitude and 118.6 degrees east longitude. The maximum wind force is 15 (50 m/s), and the lowest pressure in the center is 945 hectopascals.

  It is estimated that Du Surui will move to the north-west direction at a speed of about 25 kilometers per hour, and its intensity will gradually weaken.

  Gale forecast:From 14: 00 on the 28th to 14: 00 on the 29th, there will be 5-7 winds and gusts of 8-9 in bashi channel, northeastern South China Sea, east of Taiwan Province, Taiwan Province Strait, most of the East China Sea, southwestern Yellow Sea, Taiwan Province Island, eastern Guangdong, Fujian, Zhejiang, Shanghai, Jiangsu, eastern Jiangxi, eastern Anhui and southeastern Shandong, among which the winds in Taiwan Province Strait and southern Fujian can reach 8-19.

  Precipitation forecast:From 14: 00 on the 28th to 14: 00 on the 29th, there were heavy rains in parts of Fujian, eastern Jiangxi, eastern and southern Zhejiang, Shanghai, central and southern Anhui, southern Hebei, most of Shandong and central and northern Henan. Among them, there were heavy rains in parts of southern Anhui, northwestern Jiangxi, central and southern Zhejiang and most of Fujian, and local heavy rains (250-280 mm) in southeastern Fujian.

  Defense guide:

  1. The government and relevant departments shall, in accordance with their duties, do a good job in typhoon prevention and emergency rescue.

  2. Water operations and passing ships in relevant waters should return to Hong Kong to take shelter from the wind, strengthen port facilities, and prevent ships from anchoring, grounding and collision.

  3. Stop large-scale indoor and outdoor gatherings and dangerous outdoor operations such as high altitude.

  4. Reinforce or dismantle structures that are easy to be blown by the wind. Personnel should not go out at will. They should stay in windproof and safe places as far as possible, so as to ensure that the elderly and children stay in the safest place at home, and the dangerous people will be transferred in time. When the typhoon center passes by, the wind will decrease or stay still for a period of time. Remember that the strong wind will suddenly blow and you should continue to stay in a safe place to avoid the wind.

  5. Relevant areas should pay attention to prevent flash floods and geological disasters that may be caused by heavy precipitation.

Sogou browser 1.3 public beta version realizes "whole network acceleration"

  Since its launch, Sogou browser has been widely praised by users for its high-speed and stable acceleration function of education network. In the 1.3 public beta version released this time, Sogou browser has made persistent efforts while optimizing the acceleration function of education network, and realized the function of "whole network acceleration" for the first time after "education network acceleration", expanding the coverage of network acceleration function from education network to all domestic mainstream operator networks (Netcom/Telecom/Education Network).

Software name: Sogou browser Software version: 1.3 public beta version Software size: 2586k Software authorization: be free of charge Applicable platform: Win9X Win2000 WinXP Win2003 Vista Download address: Click to download sogou browser

  Because of the bandwidth bottleneck between China’s two major fixed-line operators (Netcom/Telecom), the slow exchange of visits between Netcom and Telecom has been called "an Internet problem with China characteristics" for a long time. Faced with this chronic disease, which has existed for about ten years, sogou proposed and realized the solutions of "breaking the bandwidth limit between networks" and "accelerating the whole network" with the attitude of solving practical problems for Internet users.

Start to accelerate
Figure 1 Turn on "Full Network Acceleration" 

  Users who use proxy servers to surf the Internet cannot use "whole network acceleration" for the time being.

Whole network acceleration
Fig. 2 The proxy "Full Network Acceleration" cannot be started.

  The whole network acceleration function of Sogou browser can increase the speed of China Netcom’s telecom exchange visits by 20%-50% on average, and the acceleration effect is more obvious for some websites with only one export (pure Netcom/pure telecom websites). After actual measurement in various network environments, most local and professional forums perform well in the acceleration effect measurement as a whole.

  At the same time, the acceleration function between the public network (Netcom/Telecom) and the education network is still effective, which can obviously improve the access speed by 2-5 times.

  In view of the misjudgment of acceleration caused by various network complex factors, we have realized the "self-learning" mechanism of automatic analysis of acceleration effect and self-improvement of acceleration strategy, so that the acceleration function can become more and more effective and accurate with the continuous use of users.

Sogou browser 1.3 beta version
Figure 3 Sogou browser 1.3 public beta interface

  Sogou browser 1.3 beta update log:

  1. New functions

  * When CNC users visit telecom sites or telecom users visit CNC sites, the access speed can be increased by 20%-50%;

  * Education network users access to the public network, and the acceleration function of public network users’ access to the education network is still effective, which can obviously improve the access speed by 2-5 times.

  2. Functional improvement

  According to the feedback from the forum users and the results of the test report, the recognition ability of the education network lines is further improved, and the acceleration effect is optimized.

  Optimize the use strategy of IE local cache, which can significantly improve the page loading speed for frequently visited websites; For forums and other types of websites, the effect is more obvious. (New in the third edition of the preview)

  Optimize the acceleration function of the whole network, increase the "self-learning" judgment mechanism, and judge whether the website needs to be accelerated more intelligently. (New in the third edition of the preview)

  3. Bug fixing (fixed some feedback concentration problems, the main problems are as follows)

  Fixed the problem that uploading large attachments may lead to disconnection after opening the acceleration function of education network.

  Fixed the problem of blank screen when extracting the "Happy Farm" game from the intranet to a separate window.

  Fixed the problem that the handle may leak after switching the whole network acceleration function for many times. (New in the third edition of the preview)

Shaoxing disease control: if a teacher is infected with the flu, he must rest in isolation at home and not attend class with illness.

CCTV News:According to the "Shaoxing CDC News" in WeChat official account, the monitoring data of Shaoxing CDC show that since November, the percentage of influenza-like cases in outpatient and emergency treatment in Shaoxing has shown an obvious upward trend, suggesting that Shaoxing has entered the influenza high season, and kindergartens, schools and other crowd gathering places are prone to outbreaks, which should be paid special attention to. It is suggested that kindergartens, schools and other collective places do the following:

1, do a good job in the morning (noon) check-up and registration of absence due to illness. Students with fever, cough and other flu-like symptoms found in kindergartens and schools should inform their parents in time to avoid going to school, and classes can only be resumed 48 hours after the students’ body temperature returns to normal and other flu-like symptoms disappear. For students who are definitely diagnosed with influenza, kindergartens and schools should do a good job in checking the certificate of resumption of classes. At the same time, the school should reasonably arrange the remedial work for students who are absent due to illness, and eliminate the concerns of students and parents.

2, do a good job of daily cleaning and disinfection. Nursery institutions and schools should use wet mops to mop the floor every day, and often carry out preventive disinfection on classroom door handles, tables and chairs, stair handrails, etc. Regularly clean the air conditioning and central air conditioning ventilation system. If there are sick students staying in the classroom, use chlorine-containing disinfectant (such as 84 disinfectant) to wipe the desks and chairs of the sick students, rinse the rag with running water, and soak it in disinfectant for 30 minutes before reuse.

3. Keep the classroom air circulating. Kindergartens and schools should open windows for ventilation at least twice a day for 10-15 minutes each time, and the ventilation time can be selected during the next class, lunch break and after school. Due to the low temperature in winter, pay attention to ventilation to avoid students catching cold.

4. If a teacher has the flu or flu-like symptoms, be sure to arrange for the teacher to rest in isolation at home and not to take classes with illness. Because of the wide range of teachers’ activities, it is easy to cause an outbreak of influenza.

5. Kindergartens and schools should provide running water, hand sanitizer and other necessary hand washing facilities, educate students to wash their hands frequently and develop good hygiene habits. When coughing or sneezing, cover your mouth and nose with paper towels and elbows, wash your hands after coughing or sneezing, and try to avoid touching your mouth, nose or eyes with your hands.

6. Vaccination against influenza is an effective measure to prevent influenza. It is recommended that school teachers and students be vaccinated against influenza every year.

7. When kindergartens and schools have a cluster epidemic of influenza-like cases, they should promptly report to the disease control institutions in their respective jurisdictions. After receiving the report, the disease control institutions should promptly assist kindergartens and schools in their respective jurisdictions to carry out on-site investigation and disposal, and take measures to suspend classes when necessary.

8, nurseries and schools in the high season of influenza epidemic, try to reduce the gathering activities.

9. During the flu season, students should try not to go to crowded public places and try to avoid contact with patients with flu-like cases. Wear a mask when you have symptoms such as fever and cough, or when you are in contact with others. In severe cases, seek medical advice in time, and do not attend class with illness.
