Establishment of Precise Histological Evaluation Criteria for NASH Fibrosis Reversal

Establishment of Precise Histological Evaluation Criteria for Reversal of NASH Fibrosis

Collect confirmed cases of NAFLD patients and enroll them in the study. Select patients with NASH and fibrosis stage F2-4 confirmed by liver biopsy, and collect clinical and pathological data for relevant evaluation and definition. Establish a NASH "fibrosis reversal" pathological evaluation system, based on a new reversal standard, establish non-invasive alternative indicators, and observe indicators.

Confirmed NAFLD patients were enrolled, and those with NASH and fibrosis F2-4 stages confirmed by liver biopsy were selected, and clinical and pathological data were collected for relevant evaluation and definition. A NASH "fibrosis reversal" pathological evaluation system was established based on the new standard, and an alternative non-invasive indicator and observation index were established based on the reversal standard.

Inclusion Criteria:

• Aged between 18 and 70 years at the time of liver biopsy;
• Gender is not limited;
• Hepatic perforation suggested that NASH complicated with fibrosis stage F2-4;
• Signed written informed consent.

Exclusion Criteria:

• Combined HCV infection, HIV infection, alcoholic liver disease, autoimmune liver disease, genetic metabolic liver disease Disease, drug-induced liver injury and other chronic liver diseases;
• Women during pregnancy;
• There are the following conditions before liver perforation: HCC or possible HCC (imaging suggests malignant liver occupation); decompensation of cirrhosis (ascites, hepatic encephalopathy, gastrointestinal bleeding, hepatorenal syndrome, etc.); Patients with other malignant tumors; Recipients of liver transplantation;
• Patients considered by the investigator to be unsuitable for this study.
