ABSTRACT
Hepatic ascites is one of the common and difficult complications in the decompensated stage of liver cirrhosis， and its incidence is increasing. In clinical practice， the prognosis of patients with hepatic ascites after surgery is worse， and the disease is recurrent. Traditional Chinese medicine （TCM） has certain advantages in treating hepatic ascites. However， there is no uniform standard for the preparation of animal models of hepatic ascites in accordance with TCM evidence. Therefore， this paper summarized the literature on animal models of hepatic ascites and analyzed the existing animal models of hepatic ascites based on the clinical diagnostic criteria of hepatic ascites in TCM and western medicine. The results show that the commonly used modeling methods for hepatic ascites mainly include the single-factor method， composite factor induction method， surgical method， and immunization method. Most of them are guided by western medicine theories， and their pathogenic mechanisms are mostly consistent with those of western medicine and are different from TCM evidence. Therefore， it is suggested that TCM intervening factors should be imposed in the process of model preparation， so as to prepare an animal model of hepatic ascites that meets the clinical evidence characteristics of TCM and western medicine.
ABSTRACT
Objective To investigate the modeling elements of various types of animal models for acute liver injury,and to provide references and suggestions to establish and evaluate animal models of acute liver injury(ALI).Methods The animal experimental literature of ALI from 2002 to 2022 was searched in the databases of the China Knowledge Network,WanFang,Chongqing Vip(VIP),Chinese Medical Journal Full Text Data(Yiigle),and PubMed.The animal species,positive control drugs,modeling method,modeling drugs,and drug administration of the animal models of ALI in the literature were summarized.The result were analyzed using Excel,SPSS Modeler 18.0,and Cytoscape 3.8.2.Results A total of 896 articles were included in the databases.The most used animal models for ALI were male KM mice.The modeling method were mainly chemical liver injury,alcoholic liver injury,drug-related liver injury,and immune liver injury.①The corresponding main modeling method were intraperitoneal injection of 10 mL/kg of 0.1％CC14 in vegetable oil at 24 h before experiments,②gavage of 12.0 mL/kg of 50.0％～56.0％ethanol at 16 h before experiments,③intraperitoneal injection of 300 mg/kg APAP at 24 h before experiments,④tail vein injection of 20 mg/kg Con A at 8 h before experiments.Evaluation of the models was based on liver pathological indexes as the gold standard combined with biochemical indexes of serum ALT,AST,and SOD and MDA contents and activities in liver tissue homogenate as direct indicators.Conclusions Because the causes of ALI vary in clinical practice,the preparation of animal models of ALI should be based on the specific study content and characteristics,and the corresponding modeling method should be selected.
