Background

Pathology, i.e., the process and principle of development of the disease. Namely the cause of the disease, the pathogenesis and the structural, functional and metabolic changes of cells, tissues and organs and their regularity in the course of the disease. Pathology is a medical science which uses a natural science method to research the changes of the etiology, pathogenesis, morphological structure, function, metabolism and the like of diseases and reveal the occurrence and development rules of the diseases so as to clarify the essence of the diseases. Basic pathology is an important branch of basic medicine. Clinical pathology is a bridge between clinical and basic medicine. Forensic pathology is a science that studies the changes and development laws of injuries, disabilities, diseases, and deaths related to law, provides medical evidence for the reconnaissance or judgment of violent cases, and applies relevant medical expertise to resolve signs of death, causes of death, patterns of death, times of death, locations of death, personal identification, and inferences of injurious objects related to violent and non-violent deaths. The pathological section, one kind of pathological specimen, is prepared through treating the pathological tissue or organ with various chemicals and embedding method to make it fixed and hardened, cutting into thin slices in microtome, adhering to glass sheet, dyeing with various colours, and examining under microscope to observe pathological change and make pathological diagnosis.
