ObjectiveTo investigate the effect of glucagon-like peptide-2(GLP-2) on intestinal barrier function in the bile duct ligated rats.MethodsSeventy-two SD rats were randomly divided into three groups:GLP-2 treated group(T group),obstructive jaundice control group (C group) and sham operation group (SO group).The mRNA expression of GLP-2R was measured by semi-quantified reverse transcription polymerase chain reaction (RT-PCR)and the bcl-2 expression in the intestinal mucosa was measured by immunohistochemistry staining equipped image analyzing systems (Image proplus Version 4.5).ResultsThe mRNA expression of GLP-2 in intestinal mucosa in T group was higher than that in C group (P＜0.05) but lower than that in SO group (P＞0.05).The expression of bcl-2 in the intestinal villi of rats in C group showed more significant decrease (P＜0.05) than those in the SO and T groups especially on day 3 and 7 after operation (P＜0.05).ConclusionsGLP-2 may increase the mRNA expression of GLP-2R,stimulate the growth of intestinal mucosa,diminish the number of the apoptosis cells,and protect the intestinal barrier function in obstructive jaundice rats.

Objective To analyze the clinical efficacy and toxic reaction of Tegafur,Gimeraciland Oteracil Potassium Capsule combined with Gemcitabine chemotherapy for patients with radical resection for advanced gallbladder carcinoma.Methods The clinical dataof 135 patients with advanced gallbladder cancer who were admitted to the 1 st Affiliated Hospital of Zhengzhou University and supported after the gastrectomy by the pathology from June 2007 to June 2012 were retrospectively analyzed.All patients were divided into three groups by different therapeutic regimens,operation groups (Radical resection or Extended radical resection of gallbladder carcinoma) with 47 cases,chemotherapy A group (Tegafur,Gimeracil and Oteracil Potassium Capsule combined with Gemcitabine chemotherapy after Radical resection or Extended radical resection of gallbladder carcinoma) with 52 cases,and chemotherapy B group (5-Fluorouracil combined with Oxaliplatin chemotherapy after Radical resection or Extended radical resection of gallbladder carcinoma) with 36 cases.We collected the dates of all patients with the median survival time and the 1,3 and 5-year survival rate after operation,and counted the rate of major toxic reaction after chemotherapy.Results There were no significant differences in the general date of three groups (sex,age,tumor size,CA19-9,CA125,TNM stages,with or without cholecystolithiasis,operation methods,operation complication),The chemotherapy A group and chemotherapy B group had no differenceswiththe median survival time and 1,3 and 5-year survival rate after operation.There were significant differences in the median survival time and 3,5-year survival rate after operation between the operation group and chemotherapy A group (or between the operation group and chemotherapy B group).There were significant differences in the rate of whole toxic reaction and the rate of toxic reaction beyond Ⅲ degree between chemotherapy A group and chemotherapy B group.Conclusions The treatment of Tegafur,Gimeracil and Oteracil Potassium Capsule combined with Gemcitabine chemotherapy for patients with radical resection of advanced gallbladder carcinoma has a lower rate of whole toxic reaction and rate of toxic reaction beyond Ⅲ degree than 5-Fluorouracil combined with Oxaliplatin chemotherapy,and for patients with advanced gallbladder carcinoma,the frontal treatment can obviously prolong the median survival time and effectively improve the 3 and 5-year survival rate after operation.
