  • The establishment of an animal model of liver regeneration in a state of neuro-endocrine-immune network dysfunction is an urgent need to promote the research on the regulatory mechanism of liver regeneration. The monosodium glutamate( MSG)-rat-liver regeneration model is a composite model of liver regeneration which combines the MSG-rat model with the model of partial hepatectomy( PHx) or hepatotoxicity( for example,CCl4),and it is mainly used to investigate liver regeneration and its regulatory mechanism in the state of neuro-endocrine-immune network dysfunction,mechanisms and drug screening of liver-brain syndrome,and mechanisms of disease-syndrome combination and drug efficacy. Dysregulated liver regeneration process is observed in the MSG-rat-liver regeneration model established by the MSG-rat model and PHx,which is significantly different from the liver regeneration process in normal rats after major hepatectomy. The MSG-rat-liver regeneration model established by the MSG-rat model and hepatotoxicity has a significantly higher degree of liver fibrosis than normal rats with CCl4-induced liver fibrosis. The hypothalamic-pituitary-hepatic axis is an important mechanism of the influence of the external environment on liver regeneration,and the imbalance of epithelial-mesenchymal transition/mesenchymal-epithelial transition is an important mechanism of the influence of intrahepatic microenvironment on abnormal liver regeneration( liver fibrosis).The research on MSG-rat-liver regeneration model preliminarily reveals the efficacy and mechanism of traditional Chinese medicine in the prevention and treatment of liver and related diseases( including liver-brain syndrome) by influencing the neuro-endocrine-immune-liver regeneration regulatory network and promotes the research on the combination of diseases and syndromes. The establishment and application of the MSG-rat-liver regeneration model has important scientific significance and application value in further exploration of the complex mechanism of liver regeneration and the mechanism of traditional Chinese medicine in regulating liver regeneration.
