Objective: To observe the effects of salvia miltiorrhizae compound (SMC) on serum endothelin (ET), TXB_2 and PGI_2 levels in patients undergoing CPB. Method: Twenty patients with congenital heart disease were randomly divided into control group (group Ⅰ) and treated group (group Ⅱ). SMC (200mg/kg) were given intravenously in group Ⅱ before operation and during rewarming, in group Ⅰ eqivalent volumes of normal saline were administered at the same time point. The serum ET,TXB_2 and PGI_2 levels were measured at preoperation (T_0) 5min (T_1), and 30min (T_2) following CPB, 10min (T_3), 30min (T_4) and 60min (T_5) following reperfusion, 24h (T_6) after operation. Result: In both groups,the serum ET level were increased significantly during reperfusion, but much less in group Ⅱ than that in group Ⅰ at T_4, T_5 and T_6(P

Objective To explore the reasons of biliary restenosis after interventional treatment for malignant obstructive jaundice caused by hepatic hilar cholangiocarcinoma and to discuss its management. Methods During the period from June 2010 to Sep. 2013 at authors’ hospital, a total of 36 patients with high biliary obstruction caused by Bismuth Ⅱ - Ⅳ type of hepatic hilar cholangiocarcinoma received percutaneous transhepatic cholangial stenting (PTCS), and as the patients developed biliary restenosis after PTCS percutaneous transhepatic cholangial drainage (PTCD) had to be carried out. All the patients had complete data. Serum total bilirubin, direct bilirubin, glutamyltranspetidase and alkaline phosphatase levels were determined on the operation day and at five days after PTCS and PTCD. The short - term remission of malignant obstructive jaundice produced by PTCS and PTCD were assessed. The causes of biliary restenosis were analyzed by comparing the CT and/or MRI images as well as the cholangiography and drainage test results which were performed at the first and second admission to hospital. Results The interval time from operation to restenosis was 31 - 468 days, with an average of 132.8 days. The effective rates of PTCS and PTCD for relieving jaundice were 77.8% and 75.0% respectively. The main causes of restenosis included the formation of biliary sludge, acute cholangitis and tumor growth. Conclusion PTCS is an effective means to relieve the malignant obstructive jaundice caused by hepatic hilar cholangiocarcinoma, however, the incidence of biliary restenosis after PTCS is higher, which may be mainly due to the tumor growth. Nevertheless, subsequent PTCD can effectively improve the liver function, control biliary infection, remit biliary obstruction and relieve the clinical symptoms.
