2. Sexual knowledge and common sense
Good sexual morality is the fundamental guarantee of sexual health, and achieving sexual health is inseparable from good and noble sexual morality. Therefore, promoting sex education has become the primary task. Lenin said that human life includes three parts: material life, spiritual life and sexual life. Therefore, sexual civilization, like material civilization and spiritual civilization, is also one of the symbols of the whole socialist civilization. Grasping the construction of sexual civilization is not only an urgent and important task facing the whole society at present, but also an urgent need of the broad masses of the people. At present, there are some decadent and backward phenomena in society, such as: whoring and prostitution are hard to stop; Sexually transmitted diseases have reappeared, growing at an alarming rate and spreading all over the country. In some places, the incidence of sexually transmitted diseases has reached 10‰ of the local population. It is estimated that there are 5000- 1 10,000 people infected with HIV in China alone. The number of induced abortions is as high as100000 every year, which reflects the obvious lack of sexual and reproductive health education. The number of patients with sexual dysfunction is estimated to be as high as 80 million to 65.438+0 billion; There are more people with disharmony in sexual life, which has become one of the important reasons why the divorce rate has doubled in recent years; With the rapid increase of premarital and extramarital sex, many teenagers feel anxious because of their psychological and physical development, which seriously affects their healthy growth and development. Therefore, it is urgent to popularize correct sex education.
At present, feudal consciousness, decadent capitalist lifestyle and low cultural quality are still serious habitual forces. On the one hand, they resist the spread of sexual scientific knowledge, on the other hand, they condone the proliferation of obscenity and pornography. For sex culture, people can neither completely suppress it nor let it grow like weeds at will. Therefore, it is necessary to provide people with accurate, scientific and practical sexual information and sexual health care services, which complement each other.
3. Health and hygiene knowledge
Beginning of autumn is coming. Let's introduce some knowledge! 1, autumn radish is better than medicine nowadays, it is the season when radish is on the market, and it is loved by people as an ordinary vegetable.

2. What should I do if my throat gets angry and my lips get dry in autumn? How to attack the "dry" enemy? In the hot summer, the summer heat emptied our body fluids, and the autumn dryness further attacked us. Friends who are busy with their careers and making money all day, the most important thing to do now is to replenish body fluids, one is to replenish, and the other is to prevent loss.
Another is to eat less greasy, too sweet, too spicy and too salty things in autumn; Diet is mainly light; Drink less sweet drinks. B, eat more coarse grains and things rich in cellulose and minerals to promote defecation.
Why is defecation related to fluid replacement? Because of long-term constipation, "fire" can't be sent out, and body fluid burns naturally. C, exercise more, exercise promotes blood circulation, and body fluids naturally overflow.
D, diet should be cold, and mutton, dog meat, shrimp, leek isothermal food should be eaten less. There are many cold foods: tofu, black beans, pears, tremella, sesame, lily, lotus root, sea cucumber, honey, eggs, bitter gourd and so on.

Comply with the growth of yang, so that lung qi can be relaxed; It is not advisable to sleep with the door closed all day or with your head covered at night, and develop the habit of living with the window open and sleeping in the open; Often open the window to ventilate, so that the indoor air circulates, which helps to reduce respiratory tract infection, dizziness, fatigue and so on.
In addition, we should keep enough sleep and consciously cope with convergence. 4. Pay attention to lunch break in early autumn. Just after beginning of autumn, the "Autumn Tiger" came.
In recent days, the sultry weather has upset people and made it difficult to sleep at night. Experts remind the public to pay attention to prevent all kinds of sleep disorders, turn on the air conditioner before going to bed, so that the bedroom can reach the temperature that is easy to fall asleep, but in order to prevent colds, it should generally not be lower than 26 C.
Pay attention to lunch break. Experts have found that an hour's nap in the afternoon can achieve the effect of sleeping for several hours at night, which is conducive to improving work efficiency in the afternoon.
In addition, proper exercise is conducive to improving the quality of sleep. 5, autumn health care needs to prevent "thief wind" Autumn is a transitional period of winter and summer monsoon activities, the climate is changeable, the temperature difference between morning and evening is large, and the heat and cold are abnormal, which often makes people unprepared, and foreign evils take advantage of it and people are prone to get sick.
The "external evil" here is what people call "thief wind". It is still very hot during the day in autumn, but at night, a cool breeze blows gently.
Some people like to sleep with the window open, so they are vulnerable to the "thief wind". This is because the activities of various organs of the human body are weakened and the immune function is reduced during sleep. Ground dust and bacteria and viruses blown by cool breeze can cause pharyngitis, tracheitis and other symptoms. The "thief wind" blows on the head and face of the sleeping person, and it is easy to cause migraine the next morning, and even the mouth is crooked and drooling. This is mainly because the virus invades the human body and causes facial paralysis; "Thief wind" blowing in the abdomen without quilt can also cause diarrhea; "Thief wind" often attracts mosquitoes to suck blood. At the same time, it spreads malaria, filariasis and Japanese encephalitis to the bitten. The "thief wind" at night also makes the muscles in a state of nervous contraction, unable to fully relax and rest, so that the muscles metabolize acidic substances and accumulate, leading to aches all over the body and fatigue the next day.
People often use "eventful autumn" to describe the changeable weather in autumn, which is probably the crime of "thief wind" To prevent the invasion of "thief wind", on the one hand, we should pay attention to dressing and covering, and don't reduce clothes because of the heat during the day; On the other hand, don't put on cotton-padded clothes too early, and it will freeze, that is, "autumn freezing", which will also increase the resistance to autumn "thief wind".
6. Eat more autumn fruits and get sick. Autumn is the season of fruit harvest, but the more fruits you eat, the better. When eating, it should be enough. Eating too much will also affect your health. For example, the following seven common autumn fruits should be eaten slowly.
Such as: apples, pears, persimmons, jujubes, oranges, grapes and pomegranates. 7. Pay attention to prevent seasonal diseases in autumn. After beginning of autumn, the autumn wind and autumn rain gradually increased, and the weather turned from hot to cold.
Because the temperature difference between day and night increases, it is also a season when people get sick more. Common bronchitis, asthma recurrence, increased gastrointestinal diseases, "cold" and so on.
Therefore, people must pay attention to health care in autumn to prevent problems before they happen. 8, abnormal cough in autumn The autumn climate is dry, and people with good health will also have itchy throat and cough, and dry cough is innocent.
Autumn wind bursts, autumn is crisp, so we should add clothes in time to prevent colds. Autumn pears are on the market, and eating 1-2 pears a day can moisten the lungs, moisten the intestines, relieve constipation and prevent cough.
In addition, kumquat has a good antitussive effect. Take 5-6 capsules three times a day, and it also has medicinal effects. 9. Anti-allergic skin in autumn Every time there is climate change, large temperature difference or warm and humid season, many women often have skin allergies.
Due to various environmental factors, allergens such as bacterial spores and pollen scattered in the air will release a large number of compounds-histamine, which are distributed in almost all tissues of the human body, causing symptoms such as stuffy nose, sneezing, runny nose, itchy throat and swollen eyelids. Therefore, some women may have itchy skin, rash and scales, peeling, different red and white faces, multi-color harmony and other allergic symptoms.
For skin allergy, antihistamines are often used in clinic. Although it can inhibit the release of histamine, it has limited effect, has no effect on many allergic symptoms, and has side effects.
Some antihistamines can make people sleepy and listless. Allergy research experts believe that the most effective measure is to find out allergens and avoid contact with this substance again.
However, it is not easy to accurately find the pathogenic factors among 20,000 different inducing factors. In order to detect the allergic reaction of a substance, doctors need to do various skin tests, which is time-consuming and laborious.
But also because many allergic substances cannot be completely avoided.
4. Campus safety, health and hygiene knowledge,
Common sense of school campus safety
1. Pay attention to safety when playing after school.
Spare time is mainly to have a good rest and prepare lessons. After class is over, don't push and shove in the walk, and don't chase and fight in the campus. So as not to collide with each other and cause injury. For example, Li, a third-grade student in a primary school in Jinhua City, Zhejiang Province, rushed out of the classroom after the bell rang one day and collided head-on with Zhang. As a result, one fell in the corner and the other fell on the steps. The two were taken to the hospital for emergency treatment. Li had seven stitches on his head, a cut on his eyebrow, and five or six stitches. She almost hurt her eyes. It can be seen that it is very important to pay attention to safety after class.
Don't play dangerous games between classmates.
Playing games can increase knowledge and exercise. However, some games are very dangerous, from hurting people to life-threatening games. There is no need for glass toys, violent toys (slingshots, bows and arrows, toy guns that fire bullets) and toys containing chemical properties. 3. Self-protection in sports activities
Regular participation in sports activities can enhance physical fitness and learn cultural knowledge better, but attention should be paid to safety:
First, put on rubber-soled sneakers before exercise. Sports shoes have great elasticity and friction, while shoes with plastic leather soles are hard and slippery and not suitable for sports.
Second, we should make full preparations, otherwise muscle strain, sprain and fracture may occur.
Third, before exercise, girls should take off hairpins, plastic or glass ornaments, and boys should not put sharp objects such as knives in their underwear.
Fourth, do equipment exercise under the protection of teachers or companions; For example, when doing single and double pole sports, do it strictly according to the teacher's requirements, especially when throwing javelin and shot put, you can't throw or pick it up without authorization, otherwise you may be hit, injured or even life-threatening.
Fifth, once you fall, don't get up in a hurry, and don't mess with your classmates, waiting for the school doctor or teacher to deal with it.
Sixth, don't drink cold water after exercise in summer, you can drink some light salt water to prevent heatstroke; Wipe your sweat and dress in time after exercise, and don't take a shower immediately to avoid catching a cold. Don't do strenuous exercise before and after meals and before going to bed.
4. Don't light mosquito-repellent incense and candles in the bedroom.
Dormitory is a place to rest. Some students study very hard, and often read books with flashlights for a while after lights out, and some even use candles for lighting. In fact, this is not desirable. Because it affects the rest of others, you can't guarantee that you get enough rest, and there are security risks. In addition, some students like to use mosquito-repellent incense to repel mosquitoes in summer, which will also cause fires. Because, when you are asleep, your body rotates, and sometimes the quilt or clothes will fall from the bed to the mosquito-repellent incense, causing a fire.

According to the World Health Organization, dental health means that there are no structural and functional abnormalities in teeth, periodontal tissue, oral cavity and maxillofacial region. The symptoms are: clean teeth, no dental caries, no pain, normal gum color and no bleeding.
Therefore, oral health refers to good oral hygiene, good oral function and no oral diseases. Although the etiology and prevention of dental caries are not completely clear at present, it is preliminarily determined that the occurrence of dental caries is related to the following four factors: a. The action of bacteria forms dental plaque on the surface of teeth, which decomposes sugar in food to produce acid, leading to demineralization of teeth. B. food factors food is too thin and sticky, easy to stick to the tooth surface, and the sugar in food is too high. It is easy to cause bacteria to multiply. C. Teeth with obvious anatomical defects (such as deep pits and cracks) or irregular arrangement are easy to cause food accumulation, which is conducive to bacterial reproduction and acid production. D the longer the above time factors, the higher the probability of dental caries. The prevention of dental caries is mainly based on prevention, and the key content of dental caries prevention is to maintain oral hygiene.
B. Conduct oral examination regularly to achieve early detection and early treatment. The treatment of early dental caries is simple, painless and effective. Once dental caries progress to pulp pain, the treatment procedure is complicated, which requires repeated follow-up, resulting in great treatment response and poor dental prognosis.
C. To improve the caries prevention ability of teeth, fluoride toothpaste can be used, and children can also drink fluoride water and rinse their mouths with 0.5% sodium fluoride solution. For children's newly erupted molars, pit and fissure sealing can be performed.
Who needs pit and fissure sealing? When is it suitable for pit and fissure sealing? 1. Generally speaking, deep pits and trenches, especially those that can jam the probe (including suspected caries); 2. The other teeth of the patient, especially the teeth with the same name or tendency to suffer from caries on the opposite side, should be sealed with pit and fissure; 3. It is suitable for pit and fissure sealing when children's teeth reach the occlusal plane after eruption, generally within 4 years after eruption; 4. The best sealing time is: deciduous molars are 3-4 years old, first permanent molars are 6-7 years old, second permanent molars are11-3 years old, and bicuspids are 9- 13 years old. The method of pit and fissure sealing is very simple, which can be completed by tooth washing, acid etching, tooth washing and air drying, sealing agent coating and curing.
After curing, the material is closely attached to the ditch wall, which has certain chewing resistance and is harmless to eating. And after curing, the material is non-toxic and harmless to human body. However, it should be emphasized that pit and fissure sealing requires professional operation and necessary instruments and equipment.
The sign of successful pit and fissure sealing is that the sealing agent can exist completely, and it is suspected that it is worn but cannot fall off, so it needs to be checked regularly, and the material falls off and needs to be re-sealed. What are the possibilities of abnormal tooth color? 1. Enamel hypoplasia: It is caused by poor mineralization during enamel development.
2. Dental fluorosis: Living in areas with high fluorine content for a long time. 3. Tetracycline teeth: Take tetracycline drugs during the mineralization period of tooth development.
4. Dental pulp necrosis: dental pulp infection caused by various reasons and tooth discoloration after necrosis. 5. Tooth coloring: Smoking, drinking tea and coffee will all cause tooth coloring.
When do you need dental implants? What's the harm in not doing it? Except for a few missing teeth, most missing teeth and complete missing teeth, after proper treatment, the shape and function of teeth can be restored by repairing the dead pulp teeth and residual roots of crown caries. Therefore, the residual roots and crowns should not be pulled out hastily, and it is best to ask a restorer to see if it is valuable. In addition, dental fluorosis, tetracycline teeth and discolored teeth with dead pulp can also be fixed with porcelain to improve their appearance. Generally speaking, it takes 2-3 months to plant teeth after tooth extraction. At this time, the wound healed completely, alveolar bone absorption and reconstruction were completed, and the denture was relatively stable after dental implantation.
Long-term failure to repair missing teeth will not only affect the appearance and pronunciation, but also affect the chewing function. It will also lead to occlusal disorder, secondary temporomandibular joint disease, occlusal trauma, periodontal disease and the health of the remaining teeth. What is the difference between removable dentures and fixed dentures? Under what circumstances are removable dentures and fixed dentures implanted? Removable dentures are called removable dentures in medicine, and patients can take them off freely.
This kind of denture has the advantages of less cutting and grinding of real teeth, convenient manufacture and low cost, but it is bulky, has a foreign body sensation when worn, and some will affect pronunciation, and has poor stability and limited recovery of chewing function. Fixed denture is a fixed denture, which is stuck in the patient's mouth without taking it off. They have the advantages of small size, stability, firmness, comfort, no influence on pronunciation and effective recovery of chewing function. However, before dental implantation, more natural teeth are cut and ground, and the cost is higher than that of removable dentures.
First of all, the patient's missing teeth should be considered, and the real teeth on both sides of the missing teeth space should also be considered. Generally, when the anterior teeth are missing 1-4, when the real teeth on both sides of the missing tooth space have sufficient height, the root is stable, the tooth tissue is healthy, and the tooth position is normal without inclination and torsion, fixed dentures can be installed.
Children with tooth dysplasia, periodontal tissue atrophy, tooth loosening and oblique dislocation are best not to choose fixed denture for restoration. As for removable dentures, most patients can install them.
How old are you to do orthodontics? Can adults do it? Theoretically, wrong? There is no strict age limit for orthodontic treatment. As long as the periodontal tissue and jaw are in normal physiological anatomy, teeth can move in alveolar bone under the action of orthodontic force to correct malocclusion. . The best time for orthodontic treatment is about 12 years old. At this time, the tooth replacement has been completed, and the development of craniofacial bone has been completed by 85%-90%. Wrong? The morphology is basically stable, but the patient is still at the peak of growth and development, and the maxillofacial region still has certain growth potential. Tissue reflects good orthodontic force, good orthodontic effect and relatively short course of treatment.
But some backbone? Deformed children may need treatment at a younger age and begin treatment at the stage of changing teeth or even deciduous teeth. At this time, the purpose of treatment is to remove all kinds of interference factors that affect the development of bones, and to promote and guide the development of bones in a direction conducive to deformity correction. After tooth replacement, these patients need to receive regular orthodontic treatment and have established a normal dentition. Adults can also do it.
