In the future, the allocation of large-scale medical equipment in the management category will be approved by the Ministry of Health, and the centralized procurement will be organized by the Ministry of Health; there will be fewer medical institutions for the clinical application of high-value medical consumables such as cardiac pacemakers and cardiac interventions. The price difference is large, and the problem of high price is more prominent. The Ministry of Health is responsible for organizing.
At present, the Ministry of Health has officially entrusted the International Exchange and Cooperation Center of the Ministry of Health to undertake the centralized procurement of high-value medical consumables such as Class A large-scale medical equipment, cardiac pacemakers, and cardiac interventions under the Ministry of Health. At the same time, large-scale medical equipment of Class B, as well as high-value medical consumables other than cardiac pacemakers and cardiac interventions, should be included in the provincial centralized procurement scope, and the provincial level is responsible for organizing centralized procurement.

The Ministry of Health requires the implementation of the evaluation and evaluation system for evaluation experts. ——Shanghai Medical Device Industry Association
Vitamins are a class of organic compounds necessary to maintain good health. This kind of substance is neither a raw material for body tissue nor a source of energy in the body, but a kind of regulating substance, which plays an important role in material metabolism. These substances are often supplied from food because they are not synthesized or are insufficiently synthesized in the body, although they are rarely needed.
Vitamins, also known as vitamins, are, in popular terms, substances that sustain life, are a class of organic substances necessary to maintain human life, and are also important active substances for maintaining human health. Vitamins are low in the body, but they are indispensable. Although the chemical structures and properties of various vitamins are different, they have the following in common:
1 vitamins are present in food in the form of provitamins;
2 vitamins do not constitute a component of body tissues and cells, it does not produce energy, its role is mainly involved in the regulation of the body's metabolism;
3 Most of the vitamins, the body can not be synthesized or the amount of synthesis is insufficient, can not meet the needs of the body, must be obtained through food;
4 The human body needs a small amount of vitamins. The daily dose is usually calculated in milligrams or micrograms, but once it is lacking, it will cause the corresponding Vitamin deficiency, which will cause damage to human health;
Vitamins are different from carbohydrates, fats and proteins. They are only a small percentage of natural foods, but they are necessary for the human body. Some vitamins such as B6.K can be synthesized by bacteria in the intestines of animals, and the amount of synthesis can meet the needs of animals. Animal cells can convert tryptophan into niacin (a type B vitamin), but the amount of production is not enough; vitamin C can be synthesized by other animals except primates and guinea pigs. Plants and most microorganisms can synthesize vitamins themselves, without having to be supplied from outside the body. Many vitamins are part of a prosthetic or coenzyme.
Vitamins are some small amounts of organic compounds necessary for human and animal nutrition and growth. They are extremely important for the metabolism, growth, development and health of the body. If you lack a certain vitamin for a long time, it will cause physiological dysfunction and cause certain diseases. Generally obtained from food. There are dozens of kinds found at this stage, such as vitamin A, vitamin B, vitamin C and so on.
Vitamins are essential organic compounds in the metabolism of the human body. The human body is like an extremely complex chemical plant, constantly carrying out various biochemical reactions. The reaction is closely related to the catalytic action of the enzyme. Enzymes must be enzymatically active in order to produce activity. Many vitamins are known to be coenzymes of enzymes or constituent molecules of coenzymes. Therefore, vitamins are important substances for maintaining and regulating the normal metabolism of the body. It can be considered that the best vitamins are in the form of "biologically active substances" and are present in human tissues.
