The combination of biochemistry theory and method with clinical practice has produced many medical biochemistry fields, such as pathological biochemistry, biochemical pharmacology centered on enzyme activity, hormone action and metabolic pathway, immune biochemistry related to organ transplantation and vaccine development, etc.
Studying the biochemical problems of some common diseases and diseases that seriously endanger human health is helpful to prevention, diagnosis and treatment. The deciphering of Helicobacter pylori makes people realize that it is the main pathogenic factor of chronic active gastritis, peptic ulcer and gastric cancer, and plays a great role in the diagnosis and prevention of diseases. The discovery of sulfonamides has opened up a new field of antimetabolic drugs as chemotherapy drugs. The monoclonal antibody of "biological missile" has the advantages of high hit rate and strong lethality to cancer cells. The increasingly mature "human organ reconstruction" technology brings hope to people with physical defects; The discovery of penicillin ushered in a new era of antibiotics and chemotherapy drugs. With the wide application of various vaccines, many infectious diseases that seriously endanger human health have been controlled or basically eliminated.
