  • Study on Protective Effects of IL-13 Gene-Modified Rattus Hepatic Stem Cells on Cold Ischemia Transplant Liver

    Objective Biliary epithelial cell (BEC) proliferated actively induced by ischemia-type biliary lesion (ITBL), which played an important role in the development of biliary complication after orthortopic liver transplantation (OLT). The aims of this study is to provide novel method to protect the liver endured cold preservation and reperfusion injury (CPRI) and reduce posttransplant biliary complication, and explore its possible mechanism.Methods Based on constructed OLT models for studying ITBL, the hepatic oval cell (HOC) or the IL-13 genemodified HOC to the portal vein of the recipient 〔OLT+HOC group and OLT+IL-13· HOC group〕 were-transfused, then the pathology change, the liver function and the expressions of the α-smooth muscle actin (αSMA) and Heme oxygenase-1 (HO-1) mRNA of the transplanted liver of CPRI were observed, the proliferation of BEC and survival rate of the recipients were also observed. Results The BEC injury was showed in grafts with prolonged ischemia time, characterized by induction of BEC proliferation, liver function injury and cholestasis sign reflecting the increase of serum ALT, AST and TBIL. The OLT+IL-13·HOC group had better results than OLT and OLT+HOC group, which indicated the OLT+IL-13·HOC group had low level of expression α-SMA (after operation 7 d, Plt;0.05) and proliferation of BEC (after operation 3 d, Plt;0.05). The expressions of HO-1 mRNA were higher in OLT+IL-13·HOC group than in other groups. The survival rate of OLT group was lower than that of the OLT+IL-13·HOC group and sham operation group (Plt;0.05).Conclusion High expression level of IL-13 in recipient rats could promote the expression of HO-1 mRNA in transplant liver, and profit to protection donor liver, and recover of the liver function after liver transplantation. It perhaps is the mechanism of protective effect of IL-13 on graft that stimulate the expression of HO-1 mRNA significantly.

  • Prophylactic Measures for Non Traumatic Complications of Laparoscopic Cholecystectomy

    【Abstract】Objective To investigate prophylactic measures for nontraumatic complications of laparoscopic cholecystectomy (LC).Methods The data of 13 000 patients who underwent LC in Kunming general hospital of PLA over 13 years(1991-2004) were retrospectively reviewed. Results Nine malignant tumors and 47 common bile duct stones were missed at LC. The 9 malignant tumors included hepatic cancer (n=1), gastric cancer (n=1), gallbladder cancer (n=2), pancreatic cancer (n=2) and right colon cancer (n=3). Of all the carcinomas, 3 patients with right colon cancer underwent colectomy, the other 6 patients couldn’t be cured radically. All the 47 patients with choledocholithiasis were cured successfully, among them 31 patients were performed with ERCP and 16 were reoperated on with cholangiotomy. Conclusion This study emphasizes the necessity to analyze carefully patients’ symptoms before operation and pay attention to pathological changes of gallbladder and intraabdominal situation intraoperatively. If necessary, laparoscopic ultrosonography can be used to avoid missing malignant tumors and biliary stones.
