GPT and Hepatic fibrosis: Hematoxylin and eosin (H&E) staining and Sirius red staining were used to observe liver tissue cell morphology and calculate the area of collagen deposition, serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) content assays were performed to assess liver function, and serum laminin (LN) and hyaluronic acid (HA) content assays were performed to evaluate liver fibrosis ECM deposition.
