Curcumin was used to interfere with acute pancreatitis model rats to explore its possible mechanism. One hundred and twenty rats were randomly divided into blank group, model group, model+curcumin group, model+mock+curcumin group, model+antagonist+curcumin group and model+curcumin+LY294002 group, with 20 rats in each group. The wet/dry weight ratio of pancreatic tissue was measured and the pathological changes of pancreas were observed by HE staining. The apoptosis was detected by TUNEL staining; the levels of serum amylase, lipase, Bcl-2 and Bax were detected by ELISA, and the levels of PI3 K, Akt and p-Akt in pancreatic tissue were measured by Western blot. HE staining showed that curcumin could improve the pathological changes of pancreas and reduce the pathological score of pancreas, while ELISA results showed that curcumin could decrease the levels of amylase, lipase and Bax in peripheral serum and increase the concentration of Bcl-2. Western blot results showed that the expression levels of PI3 K and p-Akt in pancreatic tissue of model rats were up-regulated after the intervention of curcumin, and the apoptosis rate of pancreatic cells decreased in TUNEL staining. The above effects could be weakened by miR-198 antagonist and PI3 K-Akt signal pathway inhibitor LY294002. In conclusion, curcumin has an ideal effect on acute pancreatitis, and its mechanism may be mediated by miR-198-PI3 K-Akt axis.
