Objective To improve the diagnosis and treatment of hepatolithiasis associated with cholangio-caminoma.Methods Data of 28 cases of hepatolithiasis associated with intrahepatic cholangiocarcinoma from 2005 to 2008 in Li Huili Hospital of Ningbo University Medical School were collected and analysed.Results The diagnosis was established preoperatively in 8(28.6%)cases.Twenty-one(75.0%)patients were radically resected,5(17.9%)patients received palliative operation,and other 2(7.1%)patients received exploratory surgery.In the 24 patients followed-up closely,the median survival time was 30 months in radical surgery group,8 months in palliative operation group,whereas 2 exploratory surgery cases only survived 2 months and 4 months respectively.Conclusions Cholangiocarcinoma may be related to hepatolithiasis.Early diagnosis rate is low and prognosis is poor in the cholangiocarcinoma associated with hepatolithiasis.Early radical therapy for hepatolithiasis plays an important role in preventing cholangiocarcinoma occurrence.Palliative operation for cholangiocarcinoma may improve quality of live.

Objective To establish a HPLC method for the content determination of syringin in Huoxue Tongluo Pill. Methods Chromatographic assay was performed on Kromasil C18 column (250 mm?4.6 mm,5 ?m) at room temperature,and the mixture solution of acetonitrile-1% aqueous acetic acid (10∶90,v/v) was used as mobile phase. The flow rate was 1.0 mL/min. The detection wavelength was at 270 nm. The sample size was 20 ?L. Results Good linear relationship was achieved when the concentration of syringin was in the range of 5.3～53 ?g/mL. The average recovery was 98.29% with RSD=1.71%. Conclusion The method is simple,accurate and the results are stable with good reproducibility. This method can be used for the content determination of syringin in Huoxue Tongluo Pill.

Objective To study the anti-tumor effect and liver toxicity of Oxaliplatin (L-OHP)from different outflow tracts, we implemented isolated perfusion on rabbit VX2 tumor model with L-OHP.Methods In this study, 60 rabbits in which VX2 liver cancer were established were randomly divided into three groups ( A = B = C = 20). Group A and B were taken isolated hepatic perfusion with 5 mg/kg L-OHP,while group C was normal control, which was taken isolated hepatic perfusion without L-OHP. Perfusion fluid flowed through the hepatic veins in group A, while in group B and C perfusion fluid flowed through the portal vein. Blood biochemistry、liver histopathology 、vascular endothelial growth factor (VEGF) expression and hepatocyte apoptosis index (AI) in the postoperative 6th and 12th hour were examined. L-OHP concentration was measured during the perfusion with RP-HPLC in group A and B. Results Serum ALT、AST rose significantly in all three groups in the 6th and 12th hour postoperatively, and that in group A was higher than either group B or C. Differences in serum ALT、AST level between group A and B, B and C, A and C were all statistically significant (tALT = 2. 328、tALT =7. 116、tALT =3. 124,P ＜ 0.05;tAST =2.547、tAST =4. 710、tAST = 2. 238, P ＜ 0. 05 ). The differences of L-OHP concentration in the liver and systemic circulation between group A and B was statistically significant(t =3.091, P ＜0. 05;t =2. 778,P ＜0. 05),however the difference between group A and B of L-OHP concentration in the tumor tissue and outflow tract was not statistically significant( t = 1. 461, P ＞ 0. 05; t = 0. 223, P ＞ 0. 05 ). Hepatic pathology in group A was more serious than that in group B in the 12th hour postoperatively. The levels of VEGF expression in liver tumor tissue in postoperative 12th hour, in group A and B were significantly lower comparing with group C (tAC =2.728, P ＜ 0.05;tBC =3.397,P ＜0.01). Between group A and B, the difference was not statistically significant ( t = 0. 591, P ＞ 0. 05 ). Differences in hepatocyte apoptosis index ( AI ) in the postoperative 12th hour between group A and C, A and B, B and C were all statistically significant( tAB=3. 689, P ＜ 0. 01 ;tAC = 5. 067, P ＜ 0. 01 ;tBC = 2. 607, P ＜ 0. 05 ), and with that in group A being higher than either in group B or C. Conclusions L-OHP had a significant anti-tumor effect in isolated hepatic perfusion; Chemotherapy infusion fluid flowing through the portal vein retrogradely was a more complete and safer way of regional chemotherapy than antegrade flowing through the hepatic vein.
