To explore the animal species，modeling methods，positive control drugs，and evaluation indicators used in animal models of non-alcoholic steatohepatitis(NASH)，with the aim of providing a reference for basic research on NASH.Methods:A literature search was conducted using the keywords “non-alcoholic steatohepatitis”，“animal model”，“NASH”，“Nonalcoholic Steatohepatitis”，and “Animal Model” in the China National Knowledge Infrastructure(CNKI)，Chinese Sci-tech Journal Database(CCD)，China Academic Journal Database(CSPD)，and PubMed databases.The types of experimental animals，sex，age，modeling methods，positive control drugs，and evaluation indicators were summarized and analyzed.Results:A total of 423 articles were included.The most commonly used animals in NASH models were male C57BL/6 mice and Sprague-Dawley(SD) rats.The most common modeling methods were high-fat diets and methionine-choline-deficient(MCD) diets.The modeling period was typically 56 or 84 days.The most frequently measured indicators were histopathological and serum biochemical markers，with hematoxylin-eosin(HE) staining being the most commonly used histological technique.Phosphatidylcholine was the most frequently used positive intervention drug.Conclusion:Although there are multiple methods for creating NASH animal models，limitations still exist.Therefore，data mining on NASH animal models can provide valuable insights and references for model selection and improvement.
