Liver failure is a common severe liver disease syndrome in clinical practice and is one of the critical medical conditions in internal medicine. Massive hepatocyte death is the main pathological feature of liver failure, and its core mechanisms include endotoxin, immune response, and inflammatory cascade reaction. Effective regeneration of hepatocytes to compensate liver function is the physiological basis for promoting the good prognosis of liver failure, which directly affects the prognosis and quality of life of patients with liver failure. It has been found in clinical practice that liver failure patients with a low serum level of cholesterol tend to have an extremely high mortality rate, but as an index of hepatocyte anabolism, the association between cholesterol and hepatocyte regeneration has not been taken seriously. Based on the association between cholesterol and liver regeneration, this article reviews its significance and potential value in the clinical treatment of liver failure, in order to understand the pathogenesis of liver failure from another perspective and provide new ideas for the diagnosis and treatment of liver failure and the development of drugs.

Acute liver failure is a serious and complex liver disease with a high short-term mortality rate. Its pathogenesis remains unknown and there is still a lack of effective drugs. Animal models play an important role in further revealing the pathogenesis of acute liver failure and the therapeutic mechanism of drugs, and the selection of experimental animals and preparation methods is the key to the effective implementation of research. This article summarizes the commonly used and new animal models of acute liver failure in recent years and the corresponding preparation methods and divides the animal models of acute liver failure into following four categories: chemical drug model, surgical model, infection model, and other models. Meanwhile, the above models are evaluated based on Terblanche and Hickman evaluation criteria for liver failure models, hoping to provide a reference for model selection and evaluation in basic research on this disease.
