Objective Proliferative cholangitis (PC) is responsible for stone recurrence and biliary restenosis, this study was to investigate the and-proliferative effect of CDC2 kinase shRNA on PC. Methods The common bile duct of PC rat model was given an intralumenal administration of 0. 5 ml of CDC2 kinase shRNA. Results CDC2 kinase shRNA treatment effectively inhibited the expression of CDC2 kinase,PCNA, and procollagen I , resulting in the inhibition of hyperplasia of biliary epithelium, submucosal gland, and collagen fibers. Also, the lithogenic potentiality of PC decreased due to the inhibition of endogenous β-glucuronidase secretion. Conclusion The anti-proliferative effect of CDC2 kinase shRNA on PC may prevent biliary restenosis and stone recurrence.
