RESUMEN
Liver is no longer the only organ in the concept of anatomy,but it is a concept that has some specific functions in the visceral manifestations of liver.Liver is wood in the five element theory.It is yang of yin.Liver qi connects to the spring qi.Therefore,the liver function is to dredge and smooth qi of the whole body,which influences the blood and body fluid operation,the operation of the spleen and stomach,emotional changes and reproductive function and many other aspects.Suwen said "liver stores blood",which means that liver has the function of storing,regulating and controlling blood."Liver corresponds to the spring",which means changes in four seasons can affect the function of organs,but also contain the disease occurrence with a seasonal concept,which is an important part of visceral manifestation of liver.Modern medical research achieved some results from the nerve-endocrine-immune network,traditional four-axis,liver-blood vessels as the starting point for the liver as the theoretical mechanism of in-depth study.It was found that depression due to liver failed in soothing was related to the central cortex,the marginal system and the hypothalamicpituitary-adrenal (HPA) axis.The study covered neuropeptide and neurotrophic factor,monoamine neurotransmitter,central amino acid level,and etc.Liver stores blood,which is related to human coagulation system,EPO pathway and hemorheology.Liver corresponds to the spring,which is related to the neuroendocrine-immune network.And the pineal gland may be the highest regulatory site.At present stage,the study was conducted on the microcosmic mechanism of liver visceral manifestations from the gene and protein level.It was used to verify the regulation of liver function abnormality caused by the regulation of liver function in order to greatly explore the biological basis of traditional Chinese medicine (TCM) theory.
