[Jingjin and weiqi].

This is to investigate the relationship between jingjin (the meridian of muscle region) and weiqi (the defensive qi) by referring to relevant studies. Jingjin is inherent in weiqi and originated from the meridian of foot-taiyang. It receives weiqi from the extremities and expands to several meridians of muscle regions. Jingjin is where weiqi travels and distributes. When weiqi combines with exogenous pathogens, this leads to Bi syndrome of meridian muscle regions. The analysis results in that the twelve kinds of Bi syndrome of meridian muscle regions belong to the category of Bi syndrome, which is caused by the invasion of pathogenic wind-cold-dampness into the muscle. The pathogenesis is related to the disorder of weiqi circulation. It is summarized that jingjin is closely related to weiqi and reflected in physiology and pathology, etc. The study guides to the diagnosis and treatment of jingjin diseases.
