About article:
Acute pancreatitis (AP) is the inflammatory response of the exocrine pancreas to various causes. Modafinil has significant anti-inflammation and anti-oxidation effects. No experiment has assessed the effects of modafinil on AP. Thus, the study aims to study the effects of modafinil on AP and its potential mechanism in vivo and vitro. 5% sodium taurocholate was retrograde injected into pancreatic duct to establish AP rat model. The severity of AP was detected by HE staining, serum amylase and lipase levels. The inflammation, oxidative stress and apoptosis were detected separately by ELISA, MDA and SOD kits, tunnel staining and Western blotting in rats. Besides, SNIP1 expression was analyzed by qPCR and Western blotting. In vivo, AR42J cells were stimulated by cerulein and lipopolysaccharide to establish AP cell model. Flow cytometry examined cell apoptosis. After the plasmids silencing SNIP1 were transfected into AP cells, the inhibitory effects of modafinil on inflammation, oxidative stress and apoptosis were significantly reversed. The results indicated that modafinil showed significant curative and therapeutic effects by regulating SNIP1 level.
