Abstract
Acute pancreatitis(AP) is a common digestive tract disease, often accompanied by severe metabolic disorders, but there are no specific markers and treatment methods, and the potential metabolic pathways behind it remain to be explored. Establish mild acute pancreatitis and severe acute pancreatitis models in rats and intervene with antioxidant NAC. Analyze serum oxidative stress indicators and pathological changes in pancreatic tissue. In addition, non-targeted metabolomics analysis of serum differential metabolites between groups was conducted based on the LC/MS system. The pathological score of the model group rats increased, and the levels of oxidative stress factors ROS and MDA significantly increased, while the activity of the antioxidant enzyme SOD decreased. After NAC intervention, oxidative stress damage in rats was alleviated. Non-targeted metabolomics experiments suggest significant differences in serum metabolic profiles among different groups of rats. Metabolomics results show that the obtained differential metabolites are expected to become serum biomarkers for AP.
