What is medical theory?

Medicine in a narrow sense is only the treatment of diseases, but there are also sayings that preventive medicine is the first medicine, clinical medicine is the second medicine and rehabilitation medicine is the third medicine. The scientific aspect of medicine is the application of basic medical theories and discoveries, such as biochemistry, physiology, microbiology, anatomy, pathology, pharmacology, statistics and epidemiology, to treat diseases and promote health. However, medicine also has a humanistic and artistic side. It not only pays attention to human organs and diseases, but also pays attention to people's (physical and psychological) health and life. Physiology, psychology and social model are widely accepted theories, and the care of physiology, psychology and spiritual society, the medical care of the whole person, the whole team, the whole process and the whole family are also important theories of modern medicine. With the change of medical model, the humanity of medicine has attracted more and more attention. At present, the most widely known medical ethics is the methodology of four principles: autonomy, kindness, harmlessness and justice. Medicine can be divided into modern medicine (commonly known as western medicine) and traditional medicine (including Chinese medicine, Tibetan medicine, Mongolian medicine, etc. Different regions and nationalities have corresponding medical systems and different aims and purposes. India's traditional medical system is also considered to be very developed. The research fields generally include basic medicine, clinical medicine, laboratory medicine, preventive medicine, health care medicine, rehabilitation medicine and so on. 1 basic medicine 2 clinical medicine 3 tertiary medicine 4 laboratory medicine 5 preventive medicine 6 special medicine 7 traditional medicine (1) Chinese medicine 1 basic theory 2 classical theory (2) Tibetan medicine (3) Mongolian Medicine 8 Pharmaceutical Basic Medicine Biomedical Biomedical Biomedical Biochemistry Medical Biophysics Human Anatomy Medical Cell Biology Human Physiology Human Histology Human Embryology Medical Genetics Human Immunology Medical Parasitology Medical Pathophysiology Pharmacology Laboratory Animal Science Medical Psychology Biomedical Engineering Medical Informatics Emergency Nursing New Central Regulation Clinical Medicine Clinical Diagnosis Experimental Diagnosis Imaging Diagnosis.
