Objective To evaluate the role of diagnostic and therapeutic endoscopic retrograde cholangiopancreatography(ERCP)in bile duct injury. Methods Thirty-one patients with bile duct injury from March 1999 to March 2004 were managed by ERCP. Patients with indications of endoscopic therapy were treated by endoscopic sphincterectomy(EST)and plastic stent drainage. Results Twenty-two of 31 patients with bile duct injury received endoscopic therapy . The patients included 3 cases of common bile duct transection or ligation, 13 cases of bile duct stricture, and 15 cases of bile leakage. Seven of 13 patiens with bile duct stricture received plastic stent therapy, followed for 8-20 months, 4 cases with satisfaction and 3 cases with poor outcome. Fifteen cases of bile leakage accepted EST and endoscopic nasalbiliary drainage(ENBD) , in the first time,13 cases resulted in healing of the leakage,2 cases were of no effect. Seven cases of bile duct stricture were treated with plastic stent, maintaining for 4-12 months. No procedure related complications. Conclclusions ERCP is helpful not only for diagnosing and localizing localizing bile duct injury, but also for treating it in most of patients with relatively good and safe results.

Objective To investigate the radiosensitizing effect of tetrandrine in human esophageal carcinoma cells (TE1) in vitro and its related mechanisms. Methods The cell proliferation was assessed by MTT assay. Colony formation was used to analyze radiosensitivity enhancement by tetrandrine in TE1cells. Western blotting was preformed to measure the cyclin B1 protein levels. Results Tetrandrine inhibited cell growth in a concentration and time depedant manner. The inhibition of proliferation was observed when cells were treated by 1.0, 5.0 and 10. 0 μg/ml tetrandrine for 24 h after irradiation ( P ＜0. 05;F= 3.09, 10.43 and 24. 00, respectively). The inhibition was more significant when cell were treated by 0. 1, 1.0, 5.0 and 10. 0 μg/ml tetrandrine for 48 h than 24 hours after irradiation (F =4. 12,12. 77, 44. 28, and 48.53 respectively ,all P ＜ 0. 01 ). The D0, Dq and SF2 decreased with the increase of the tetrandrine concentration. The maximal sensitizing enhancement ratio was 1.60 with 0. 5 μg/ml tetrandrine. Tetrandrine upregulated the expression of cyclin B1 and removed G2 / M arrest . Conclusions Tetrandrine can enhance radiosensitivity of TE1 cells. This effect may be associated with the increase of cyclin B1 expression to remove G2/M arrest.
