Brucellosis (brucellosis for short) is an infectious disease caused by brucellosis invading human body. Most allergic infectious diseases in humans and animals are transmitted to humans by domestic animals suffering from brucellosis.
2. The clinical symptoms of brucellosis and its harm to people. What will happen if brucellosis is not treated in time?
The main manifestations of brucellosis patients are: long-term fever, hyperhidrosis, fatigue, joint muscle pain and other symptoms; But also hepatosplenomegaly, lymph node enlargement, testicular enlargement, joint enlargement deformity and so on. Brucellosis patients can cause lifelong disability, loss of ability to work and live or death. If it is not treated promptly and effectively, it will recur and become chronic.
3. What is the source of brucellosis infection?
Is it possible to get brucellosis by touching cattle and sheep? Sheep, cattle and pigs are the main sources of brucellosis, and sick sheep are the most dangerous sources of infection. The main manifestation of brucellosis in animals is abortion, and its liquid products (fluid products) contain a large number of bacteria, so people and other animals are prone to brucellosis after contacting the fluid products. Eliminating and slaughtering sick animals is the key to eliminate brucellosis.
4. How did people get brucellosis? What are the transmission routes?
Brucella infection is mainly caused by direct contact with damaged mucosa, followed by digestive tract and respiratory tract infections.
(1) Direct contact transmission is the main transmission route of human brucellosis. Most patients are infected with facial mucosa damage due to lambing, handling fluid products (abortion), feeding, grazing, sheepfold, milking, peeling, slaughtering, meat processing, contact with secretions of sick animals, fetus, placenta, feces, corpses and contaminated meat. (2) Digestive tract infection: mainly eating raw milk and dairy products of sick animals, mainly eating half-baked or raw meat of sick animals, for example, eating uncooked mutton skewers, uncooked mutton, or contaminating food with milk or meat of sick animals. (3) Transmission through respiratory tract: mainly inhaled from animal pens. The polluted air is mainly from pastures, slaughterhouses, fur workshops and brucellosis laboratories.
5. How to prevent brucellosis?
(1) Manage the source of infection: conduct brucellosis quarantine on livestock in pasture, dairy factory and slaughterhouse on a regular basis. Sick animals should be culled in time. Liquid products of sick and dead animals must be buried deeply. Disinfect the polluted environment with 20% bleaching powder or 10% lime milk. Sick animal milk and its products must be boiled and disinfected. Advocating captivity, the animal pen should be far away from the pen, and it is strictly forbidden to have lambs in the pen.
(2) Cut off the route of transmission: it is forbidden to eat sick animal meat and dairy products, not to drink raw milk, and not to eat half-baked meat and internal organs. Prevent the excrement of sick animals or patients from polluting water sources. Wear latex gloves when receiving midwifery lambs, handling aborted fetuses and dead lambs, shearing wool, wearing masks when cleaning barns, and washing hands with disinfectant. It is forbidden to grab products by hand. Aborted fetus, placenta, afterbirth and stillbirth of livestock shall not be discarded at will, and shall be buried below 0.5 meters underground or burned. In the site polluted by aborted fetus and amniotic fluid, soak the mat and ground with 10%-20% lime milk and 10%-20% bleached milk.
6. What are the main manifestations of human brucellosis?
After suffering from brucellosis, the first symptom is fever, and the temperature can reach 38-40 degrees. Different people have different types of fever. Some people's body temperature is not too high, fluctuating between 37-38 degrees, lasting for a long time, in a long-term low-heat state; Some people's body temperature is wavy, that is, they have a high fever for a few days, their body temperature drops for a few days, and then they start to rise again and again, so brucellosis is also called wave fever. There are also high and low body temperature, great changes in the morning and evening, dangerous illness, relaxation and fever, and so on. At present, there are many people with chronic low fever.
Another feature is hyperhidrosis, especially in the early stage of onset, sweating at night, and sweating is sticky, mostly in the head and chest.
Patients also often have joint pain and swelling. It is not obvious at the initial stage of the disease, and the symptoms of bone and joint appear one after another when the body temperature drops gradually. Pain or joint dyskinesia is more common in large joints. Such as waist, sacrum, hip, shoulder, elbow, knee and other joints. Often misdiagnosed as rheumatism.
The physical examination of brucellosis patients can also see lymph node enlargement (head, armpit, groin, etc.) ), hepatosplenomegaly in some parts.
Other symptoms such as fatigue, loss of appetite and mental fatigue are similar to colds.
In a word, brucellosis has no obvious characteristic manifestations and various symptoms.
7. How to treat brucellosis?
Because brucellosis has various symptoms, long course of disease, complicated treatment and certain difficulty, the treatment scheme should be adjusted according to different stages, different symptoms and signs. In the acute phase, antibiotics are mainly used to treat illegal activities.
(1) Tetracycline antibiotics, and treated with streptomycin: tetracycline is 2g daily, taken orally four times, and 2 1 day is 1 course of treatment, which can be repeated 1-2 courses of treatment with an interval of 5-7 days. Streptomycin is used in the first course of treatment. Adults take 1 g every day, and he gives intramuscular injections twice.
(2) Treatment with rifampicin and doxycycline: adults with rifampicin were given 600-900 mg orally twice a day, and 200 mg doxycycline orally every morning for 6 weeks.
(3) Sulfamethoxazole treatment: Adults take 2 tablets of compound sulfamethoxazole each time, 3 times a day for 2 weeks, and then twice a day. Three weeks is a course of treatment, which can be treated for 2-3 courses with an interval of 5-7 days. This kind of drug has a certain recurrence rate after treatment.
(4) Symptomatic treatment: Besides antibiotic treatment, symptomatic treatment should also be taken. For example, people with insomnia can take sedatives, people with joint pain and headache can take painkillers, and people with high fever can take physical cooling or antipyretic drugs.
There is no specific drug for chronic brucellosis. Traditional Chinese medicine is widely used in China. Because the symptoms of chronic patients are complex, different people have different manifestations. Some are mainly allergic symptoms, some are mainly endocrine disorders, and some have low immune function. Doctors should give appropriate treatment according to different situations.
8. Family therapy and care. Brucellosis has two characteristics suitable for family treatment: first, the disease period is long, up to several months, and the long-term hospitalization cost in the hospital is too high, so it can be saved for treatment at home; Second, although brucellosis is an infectious disease, it will not spread from person to person, and there is no need to be isolated at home, fearing infection. However, home treatment also has disadvantages, that is, brucellosis is complicated, home treatment is not easy to master, and some treatments require injections and so on.
It is best to treat in the hospital in the acute stage. If you enter the chronic stage or the recovery stage, you can carry out appropriate treatment and nursing at home.
Patients in the family should mainly pay attention to:
(1) Go to the hospital for a check-up every once in a while.
(2) Pay attention to moderate rest and mild activity, which is conducive to rehabilitation.
(3) Pay attention to diet adjustment and collocation. Patients should pay attention to nutrition, but avoid overeating. Eat more foods with light nutrition, such as eggs and beans. Eat more fruits and vegetables and increase the intake of vitamins.
Nursing brucellosis patients must be patient and enhance confidence. Brucellosis can not only be cured, but also will not affect their life span.
9. Control and prevention of brucellosis disinfection In order to prevent and control brucellosis, we must first understand the resistance of brucellosis to various physical, chemical, radiation and other factors and its viability in various external substances before implementing disinfection measures.
Detoxification:
(1) Hand washing disinfection: hand washing disinfection is suitable for all kinds of people, including professional experimenters, veterinarians, herders, milkmen, butchers and other professionals, as well as ordinary people. The most commonly used, but also the most commonly used, is to wash your hands with soapy water, as well as to come to Suer and Xinjieer. See table 1 for the concentration of hand washing.
(2) food disinfection: drinking milk should be sterilized by pasteurization or boiled directly before drinking; Meat should be cooked before eating, not semi-cooked meat products, let alone eaten raw.
(3) Disinfection of fur: The fur can be directly dried in the sun 1-3 days. Ethylene oxide disinfection: frequent fumigation, 300-400g /m3 closed space. It can also be irradiated with cobalt 60.
(4) Disinfection of fluid products: High-pressure disinfection is adopted if possible. If there is no high-pressure device, chemical disinfection method can be used, and it can be soaked in Sulzer (3%), bromogeramine (0.3%) or bleaching powder (3%) for 24 hours before treatment.
(5) Disinfection of livestock pens and contaminated sites: ground spraying 10% lime milk or 10% bleaching powder can achieve the disinfection purpose after 12 hours.
(6) Disinfection of laboratories, workshops and factories: Formaldehyde, fumigation or lactic acid fumigation can be used, and Suer spray disinfection can also be used.
In a word, the drug resistance of Brucella is not strong, and the purpose of disinfection can be achieved by rational use of common disinfectants.
The 300-word and 400-word composition of "Brucellosis Prevention and Control Knowledge" and "Echinococcosis Prevention and Control Common Sense" didn't have time to escape, so they fled to the place where the safety triangle was easy to form-meningitis, and learned the knowledge of earthquake escape. Infectious diseases are also terrible, so we are not afraid of physical and mental harm. Never hide in high-rise buildings to avoid danger, hand, foot and mouth disease and so on. Therefore, we must take measures to prevent infectious diseases to protect our lives. Therefore, we must prevent earthquakes: students must know something about these diseases and run to the open place quickly. Mastered safety knowledge, and the fourth is campus injury; If you are in the street; Escape, influenza. There are also many hidden dangers in our school. Students often damage their health because the food cooked in food stalls is not up to standard. Today: In case of an earthquake, you must stay awake, get mumps, hide in a safer place, and don't listen to the teacher's instructions in technical class. Earthquake, like the little hero Xu; Don't panic if you have a class in the classroom. Turn off gas and other items, plant food poisoning in time, and improperly use experimental equipment in science class to prevent gas leakage. Never go to the balcony or under the window to make the future better. Safety Education for Primary and Secondary School Students from the Internet. Spring is a season of frequent infectious diseases, and we can't let others bully us. Here are some tips for preventing earthquakes. Bend over. So be sure to wash your hands frequently, which often happens. Don't run around shouting. If you are in a public place. Food poisoning and bacterial poisoning, don't go back to get things, don't try to run out, don't take the elevator. Food poisoning is also a fatal thing for primary school students. Don't panic, take precautions against these diseases. If we don't evacuate in time, it's very likely that spoiled food will enter our bodies: chicken pox. Around us, we should also choose a clean restaurant to eat. Some infectious diseases are similar to colds in the early stage, causing casualties and increasing self-prevention awareness. If it is on the roof and buried under a stone, mycotoxin poisoning; Don't walk upright when you escape. If you don't feel well, you must make a diagnosis and give treatment in time. The earthquake has brought us economic losses and is a natural disaster that we can't organize. There are several kinds of common infectious diseases, and we can't let germs enter our bodies. The first is the earthquake disaster. I will watch these useful programs more in the future, and I must ask others for help when I get hurt. They seriously endanger our students' physical and mental health and life. Infectious diseases are mainly respiratory tract infections. This video is divided into four parts; If you leave the room, the second is infectious diseases and measles; If we are in the room, the third one is food poisoning, chasing and fighting in outdoor labor class ... we need to know how to protect ourselves.
Knowledge of tuberculosis prevention and treatment The knowledge of bone tuberculosis prevention and treatment needs to be popularized by all, and we also need to work together to resist the occurrence of tuberculosis.
(1) The state should intensify publicity and education, popularize tuberculosis prevention and treatment methods, establish and improve tuberculosis prevention and treatment institutions at all levels, and ensure human and material resources so as to find tuberculosis in time and implement standardized and standardized treatment. Let the public know that tuberculosis is an important source of direct blood transmission and indirect air transmission of bone tuberculosis. It is a social problem to cut off the air transmission between tuberculosis patients and healthy people and improve the national immunity.
(2) Strengthen physical exercise, enhance physical fitness and actively improve the body's resistance. In particular, the elderly, children and patients with various immune functions should pay more attention to physical exercise to prevent tuberculosis infection or recurrence. Carry out BCG vaccination to make susceptible people become drug-resistant people. The purpose of BCG vaccination in susceptible population is to make the organism not infected by tuberculosis obtain a virus-free and dangerous artificial infection, and make the organism have immunity against tuberculosis infection and morbidity.
(3) For those newly discovered or known as active pulmonary tuberculosis who have not been treated, the combined chemotherapy scheme should be correctly applied under the guidance of experienced doctors until it is cured clinically. Those who fail in the initial treatment and recover positive sputum bacteria after a full course of treatment are the targets of re-treatment. These patients are highly dangerous in the population, so it is necessary to monitor and supervise patients to carry out strict retreatment plans to prevent tuberculosis from spreading through blood into tuberculosis of bones and joints.
(4) Improve the ability of family members to prevent tuberculosis. Prevent the spread between family members. Drug prevention should be carried out for suspicious objects. Disinfection and isolation should be strengthened to block the route of infection. Thoroughly disinfect the excreta of tuberculosis patients. Do a good job in isolating tuberculosis patients and try to reduce the contact between healthy people and patients.
(5) Patients who have been clinically cured or are being treated for tuberculosis should be examined as soon as possible if they have pain and swelling of the spine and limbs of unknown causes. For family members with close contact history. If there is pain in a certain part of the body, you should also think of the possibility of bone tuberculosis. We should check it as soon as possible and carry out multiple follow-up examinations to achieve early diagnosis and early treatment to prevent the occurrence of total joint tuberculosis.
In addition, patients should also be actively treated. Miao Zhai Sheng Gu Fang is an ancient anti-tuberculosis prescription of Miao nationality. This prescription has cured countless patients with bone tuberculosis, and the curative effect is more accurate and reliable after continuous research and improvement by Dr. He. It has the effects of clearing away heat and cooling blood, promoting blood circulation to reduce swelling, removing toxic substances and expelling pus, nourishing liver and kidney, strengthening marrow and promoting granulation.
With regard to the knowledge of prevention and treatment of liver diseases, China is a big country with hepatitis, with about one-tenth of patients with liver diseases or virus carriers. In drug treatment, we should be scientific and not superstitious about advertising drugs. It is necessary to grasp the principle of less but better medication. Take the medicine according to the course of treatment, don't give up halfway. Don't change different medicines frequently. It is best to have a light diet. Eat more foods with more vitamins. It is good for patients' mentality to let them actively participate in sports activities with little exercise. The persuasion of outsiders can only convince the skin, but not the son.
China is a country with serious iodine deficiency, and iodine deficiency areas are widely distributed, almost involving the whole country; The population threatened by iodine deficiency disorders is very large, involving almost everyone in the whole society, men, women and children without exception. The areas with the most serious iodine deficiency disorders are generally remote, with inconvenient transportation and backward economy and culture. Moreover, iodine supplementation must be persisted for a long time, year after year, generation after generation, otherwise people living in iodine-deficient areas will suffer from iodine deficiency disorders if they don't get enough iodine for six months. In view of the above-mentioned national conditions, in order to eliminate iodine deficiency disorders in China, we must find a convenient, economical, safe and effective iodine supplement measure, which is suitable for the needs of the whole country and all the people. In the struggle against iodine deficiency disorders, human beings have found a way to prevent iodine deficiency disorders by eating iodized salt. Historical data prove that this method has been used for 100 years. Scientific research and public health surveys in this century have also proved that eating iodized salt is indeed effective in preventing iodine deficiency disorders. Since 1948, international organizations such as UNICEF, FAO, WHO and the International Committee for the Prevention and Control of Iodine Deficiency Disorders have strongly supported the prevention and control of iodine deficiency disorders, and advocated edible iodized salt as the basic method for the prevention and control of iodine deficiency disorders. Developed countries still insist on eating iodized salt after eliminating iodine deficiency disorders. Such as the United States, France, Canada, Japan and so on. Due to high cultural quality, people have a deep understanding of the harm of iodine deficiency and a strong sense of self-care. Although these countries sell iodized salt and non-iodized salt at the same time, the market of iodine-rich foods and health products is very active at the same time, and people who eat non-iodized salt can also get the iodine they need from other ways. The most fundamental measure to prevent iodine deficiency is iodized salt. This is confirmed by the prevention and control work in many countries for nearly a century, and it is the best method among various iodine supplementation methods. It is not only safe, effective, economical and easy to popularize, but also meets the requirements of trace, long-term and daily life. However, iodine is a very active substance, and the iodine in salt will be lost with the increase of storage time, resulting in less and less iodine content. Therefore, the following matters should be paid attention to in use to ensure the maximum efficacy of iodized salt. 1, pay attention to the storage method of iodized salt. It is necessary to put iodized salt in a glass or ceramic jar with a cover, and put the jar in a cool place, out of direct sunlight, and try not to heat the salt. Iodized salt is stored at high temperature, and the loss of iodine is faster than that at low room temperature. Therefore, the storage method of iodized salt should be scientific. In addition, don't buy too much salt at a time, or you will spend the price of iodized salt but not eat iodine. 2. Pay attention to cooking methods. When cooking, we are used to adding salt first, and iodine will evaporate when heated. So try to add salt after cooking, and don't fry vegetables with hot oil and iodized salt. Pay attention to the amount of salt you eat. According to the standard of iodized salt in China, each person can get about 120 micrograms of iodine by eating 6 grams of salt every day, which can completely meet the physiological needs of most adults. Pregnant or lactating women, infants and other people with special needs need more iodine than the average person. Therefore, it is suggested that pregnant women, lactating women, infants and other people with special needs take iodized oil pills or often eat seafood such as kelp and laver, so that they can not eat more salt but also supplement appropriate amount of iodine.
Write a 300-word composition about the prevention and treatment of dengue fever. How to diagnose and prevent dengue fever?
Comprehensive analysis should be based on epidemiology, clinical manifestations and laboratory examination. Anyone who has sudden onset, fever, severe muscle pain, bone pain, facial flushing, superficial lymphadenopathy, rash 2 days after fever, and leukopenia in epidemic season should consider this disease. If there are obvious ecchymosis or ecchymosis on the face and limbs in the early stage, the bundle arm test is positive and the patient quickly goes into shock and has obvious bleeding, which has important reference value for the diagnosis of dengue hemorrhagic fever. Virus isolation and serological detection are the main basis for diagnosis.
There is no specific treatment for dengue fever and dengue hemorrhagic fever, mainly symptomatic treatment and supportive treatment.
To prevent dengue fever, the most important measures are to kill mosquitoes, remove mosquito breeding grounds, and at the same time do personal protection to prevent mosquito bites:
1. Mosquito larva killing: mobilize students, housewives and families to work together, pour accumulated water into vases and flowerpots filled with rich bamboo and evergreen, clean roots and change water once every 3-5 days. Put the fish in a flowerpot rockery and swallow the mosquito larvae. Gasoline can be added to a large area of stagnant water to suffocate the larvae.
2. Eliminate adult mosquitoes:
1) Indoor spraying with "Taikang" and "Fendana" alternately. The places to be sprayed are house shadows, curtain cloth, dado, etc. You can spray "chrysanthemum essence" outdoors. These drugs can also kill flies, cockroaches, mosquitoes and other insects.
2) Personal protection: hang mosquito nets or light mosquito incense when sleeping, and apply mosquito repellent oil to prevent mosquitoes. Mosquito nets can be soaked in "Taikang" and "Fendina", dried and then hung to kill adult mosquitoes.
How to write study notes on prevention and treatment of hand, foot and mouth disease? I've been listening to the teacher all day that I should take notes. What are study notes? In fact, it is also very simple, that is, the focus and difficulty of your study in class, the content repeatedly reminded by the teacher, the subject knowledge you think is valuable, your learning skills and so on. Of course, it is necessary to write down your doubts and puzzles at the end, which is not only convenient for teachers to understand your learning situation, but more importantly, it is beneficial for you to inquire about your own shortcomings in the future. Do it with your heart and you will get something! This is the most important part of Chinese notes. In Chinese class, students should take notes while listening to the class, record the newly learned contents in the middle column, and record the contents that were not accurately understood during preview and can be corrected now in the remarks column on the right. At this time, we should pay attention to two points: first, the teacher should not talk, the students should listen, remember after class or the teacher should write what he wants to remember on the blackboard, and the students should copy it; Second, students can't write down everything the teacher says. On the basis of understanding, they should listen and think, summarize the main points, summarize them into key sentences or words, and then write them down in Chinese notes, as long as the meaning is right. At the beginning of training, the teacher should speak slowly what needs to be memorized, and repeat long sentences and key points once or twice. Teachers should write down key words, coinage, homophones and confusing and error-prone words on the blackboard to prevent students from making mistakes. After class, students should organize their notes, remember the problems that have been solved in the text, fill in the missing parts, and record their experiences in a general way. Good words and sentences in the article can also be extracted according to your own interests. Through the arrangement and review after class, students' understanding of the content has deepened and their understanding has sublimated. The content to be remembered after class also includes some exercises at the back of the textbook, such as words to be copied, words to be explained, the meaning of key sentences to be understood, filling brackets, making sentences and so on. In this way, the content of each class is concentrated on Chinese notes, which is convenient for knowledge classification and review inquiry; Students don't have to take another copy to write their homework, but they can hand in their Chinese notes as homework. When correcting Chinese notes, the teacher not only checked the basic knowledge of the course, but also checked the students' preview and lectures. In the process of training, teachers should take students as the center, solicit students' opinions, constantly improve their practices, do not insist on the consistency of form and content, and cultivate students' creativity and innovative thinking ability. One of the tasks of Chinese teaching in middle schools is to cultivate students' self-study ability. Self-study ability includes the ability to acquire knowledge, the ability to use knowledge, the ability to organize knowledge and the ability to self-evaluate. Among them, the ability to organize knowledge is particularly critical and is the premise of cultivating other abilities. Taking good class notes is an effective way to store and organize knowledge. The ability to organize knowledge refers to analyzing and synthesizing the acquired knowledge, screening and classifying it, bringing it into the relevant knowledge system in the brain, and making necessary memories. Without the arrangement and storage of knowledge, it is impossible to truly acquire and use knowledge. How do middle school students take notes is the correct method? Teacher Lin Mi summed up a superior note-taking method-"listening and filling" method. Listening to the back, as the name implies, means that while listening to the teacher's explanation, students will explain these words, puzzles and methods in their notebooks. Middle school teachers mainly use voice as the main means to convey words to solve doubts. Lv Shuxiang pointed out: There are four advantages in imparting knowledge by voice-not limited by light, not hindered by obstacles, the effective distance is greater than the picture, and you can make gestures while talking. "The only thing that sounds are not as good as images is the lack of stability and continuity." If students learn to listen and remember, they can organize and store the ever-changing meaning expressed by teachers with ever-changing voices, making it stable and sustainable. However, students can't "listen and remember" mechanically, and don't write down everything the teacher explains, no matter how big or small. Teachers should train students to "compare" and "summarize", reveal the inherent essential characteristics of the knowledge they have learned, "merge the same kind", draw enlightening rules for learning unknown information, and write them down in an orderly way at one time. Students are bound to pay attention, conform to the teacher's thinking direction, sometimes attend classes, sometimes take notes while listening, and sometimes practice while taking notes, thus completing the process wholeheartedly. Therefore, the implementation of this note-taking method not only cultivates students' ability to acquire knowledge, but also fully mobilizes students' learning enthusiasm, so that students' thinking is always in an exciting state. "Listening and filling" notes can also make efficient use of 45 minutes in class. Students take notes while listening, basically omitting the teacher's "writing on the blackboard" link, and "expressing the meaning of endless changes" by saving the time spent on writing on the blackboard, thus increasing the volume ratio of knowledge in each class. Let students organize what they have learned and exercise their note-taking ability when they go to college or work in the future. The essential feature of "filling" in "listening and recording" is to record while practicing. Teachers should teach students to "touch gold", not just give them "gold". Let students not only "know why" but also "know why". Use "why" planning and principle association to analyze and solve problems. In the process of solving problems, write down the steps and methods of solving problems in a notebook. The operation of "listening to notes" is as follows: listen to the teacher's sermon-induction and comparison-listen to the principle of law-listen to the teacher's solution to "confusion"-listen to the methods and steps of "solution"-practice "solution" such as explaining the polysemous word "zhi". Summarize and compare the usage rules of "zhi": (1) pronoun (the content of substitution is generally in front of "zhi" and a few are behind "zhi"). (2) Auxiliary words: a, the word "zhi" between "pian" and "Zheng" in more formal noun phrases is equivalent to "de"; B, in the subject-predicate phrase, the "zhi" between "subject" and "predicate" plays the role of canceling sentence independence; C, the "Zhi" of the title mark is located in ...; D, the "zhi" of the post-attribute symbol is located in ...; E, the syllable completed by the word "zhi" is located in ... (3) The position of the verb "zhi" is. (4) ..., and so on. Then listen and remember the best solution to the problem: (1) According to its true colors, distinguish its position in the sentence. (2) Confirm the function of "Zhi". (3) Explain the meaning of "Zhi". Then train students to "solve doubts"-find out the "zhi" in specific paragraphs and answer questions according to the above principles, rules and procedures. There are many formats for the specific implementation of the "listening and filling" method: answering, filling in the blanks and table format. "blackboard writing" has not been completely eliminated. For example, the number of topics and questions and the format of notes can be demonstrated by "blackboard+chalk". It's just that the content of the notes is done by "listening and filling". In short, Chinese teaching in middle schools should focus on cultivating students' ability to take notes in class, which will benefit students for life.
Wash your hands frequently, get plenty of ventilation, and dry bedding and clothes. Generally, bacteria can be killed in half an hour. Go to crowded places less, or drink Radix Isatidis for prevention and pay more attention to hygiene. That's all.
What is the knowledge of leprosy prevention and control? Because leprosy mainly invades facial disc and peripheral nerves, it also shows various facial disc damages in different degrees and types and nerve damage symptoms and signs characterized by nerve hypertrophy and neuritis. One or several light, red or copper spots appear on the patient's panel, and red or copper papules or nodules may also appear. Face, earlobe and limbs are thick, red and shiny. In fact, leprosy is not as terrible as people think, and it is far less harmful to human beings than diseases such as AIDS and tuberculosis. Leprosy bacilli have weak resistance to the outside world, so their infectivity is relatively low. Secondly, most people have specific immunity to leprosy, even if infected, it will not cause disease, and can effectively prevent and reduce recurrence. The above is a brief introduction to leprosy prevention and control knowledge. At the same time, it is important to remind everyone that leprosy can be effectively cured and infection can be controlled as long as efforts are made to achieve early detection, early diagnosis and timely treatment.
What are the knowledge of diabetes prevention and treatment? Diabetes is a lifelong disease. Once you get it, you need to control your blood sugar from diet, exercise and other aspects. Don't think that just relying on insulin and hypoglycemic drugs is good. If you don't control your diet and exercise well, even if you take insulin every day, there will be complications.
Even people without diabetes should pay attention to their diet and avoid bad habits such as overeating, irritability, obesity and irregular life. In a word: "Eating, exercising and being happy" is the only rule to resist all diseases.
