2. Cancer: It affects all walks of life and threatens the whole world. Its incidence rate is on the rise, younger, and its morbidity and mortality rate are very high, which has caused great losses to society, families and individuals. It belongs to the second killer.
3. Diabetes: The syndrome of glucose, protein and fat metabolism disorder caused by stress, fatigue, mental stimulation, viral infection, obesity, trauma, surgery, childbirth, other major diseases and drugs that raise blood sugar, which leads to insulin deficiency or increase of insulin antagonist hormones, or insulin can not play its normal physiological role in target cells. Its main manifestation is the typical "three more and one less" symptom.
In the 1970s, the prevalence rate was less than 1%,165438+3.2% in 1996, and now it has reached 40 million, with an annual increase of 1.2 million and an increase of 3,000 people every day. According to wHO's prediction, by 20 10, the number of diabetic patients in China will reach10.2 billion. The incidence rate is younger: grandparents are 60-70 years old, parents are 40-50 years old and children are 20-30 years old. Therefore, the prevention and treatment of diabetes is imminent.
4. Infectious diseases:
(1) atypical pneumonia: SARS for short, respiratory infectious disease, caused by a kind of novel coronavirus. It has been found and reported in 17 countries and regions all over the world, which has attracted great attention from the country and WHO.
Clinical symptoms: history of contact, acute onset, with fever as the first symptom (some cases have no fever at the initial stage, mostly above 38℃), chills, headache, general aches, fatigue, cough, less sputum, occasional bloodshot, and even respiratory distress syndrome in severe cases.
The examination showed that the lung signs were not obvious, some of them had dry and wet rales, or lung consolidation signs: the white blood cells were not high or decreased in laboratory examination, and there were flaky, patchy infiltration shadows or reticular changes in lung X-ray or CT examination, and a few people could see large shadows; Shadow absorption and dissipation are slow. Antibiotic treatment has no obvious effect on this disease.
Prevention and treatment: prevention-oriented, enhancing immunity, injecting preventive vaccine, and most of the treatments are symptomatic treatment and antiviral treatment.
② Viral hepatitis: Classification: A, B, C, D, Shu, etc.
There are 690 million people suffering from hepatitis in the world;
Hepatitis B; The average incidence was10%;
Of the 300,000 people who die of liver cancer every year in China, 6.5438+0.5 million are caused by hepatitis;
Hepatitis has been listed as a sexually transmitted disease abroad, and blood and contact are the main transmission routes;
Treatment: antivirus, liver protection and immunity enhancement;
③ AIDS: In 2000, there were 40 million person-times in the world, with Asia accounting for 25 million. Blood transmission, sexual transmission and mother-to-child transmission are the main transmission routes of AIDS.
Modern medical research proves that:
Hyperlipidemia, high blood viscosity and hyperglycemia are the bane of coronary heart disease, cerebral thrombosis and diabetes.
Due to the increase of blood lipid and blood viscosity, it is easy to form atherosclerotic plaques, blood vessels are seriously aging, and blood supply is insufficient, which leads to the threat of life-sustaining heart and brain (cardiovascular and cerebrovascular diseases).
At present, the average life expectancy in China is only 7 1 year, and the healthy average life expectancy is only over 30 years old. Who took nearly half of our lives and shortened our life span by 50 years? It is the four killers that endanger human health: hypertension, coronary heart disease, tumor and diabetes.
In China, the problem of cardiovascular and cerebrovascular diseases is more prominent, and the incidence and mortality rate are among the highest in the world, with an average of 300 deaths per hour, which seriously endangers people's health.
The characteristics of cardiovascular and cerebrovascular diseases: large concealment, long incubation period, easy to be ignored and miss the best diagnosis and treatment period, asymptomatic when blood vessels are blocked for 25%, and stroke will occur only when the blockage exceeds 90%.
Cardiovascular and cerebrovascular diseases have become the first cause of death among Chinese residents, accounting for 35% and 32% of the total deaths respectively. According to the data collected by the Ministry of Health in 2000, the per capita expenditure of patients with acute myocardial infarction and cerebral thrombosis was 10489 yuan/year and 6566 yuan/year respectively.
