ABSTRACT
To treat residual or recurrent stones after operation on hepatolithiasis conveniently and effectively, a subcutaneous permanent tunnel to bile duct (SPTBD) was established in 564 cases of hepatolithiasis by using an afferent jejunum or a well-functioned gallbladder in order to provide a postoperative way to remove residual or recurrent stones through cholangioscopy. We found that by cutting SPTBD open to remove residual or recurrent stones through cholangioscopy in 96 out of 238 followed-up cases, all the patients got good clinical effects without death or complications. The results suggest that it is a good method to establish a SPTBD during operation in patient with hepatolithiasis. It is a simple and effective way to cut SPTBD open to remove residual or recurrent stones after operation.
ABSTRACT
ObjectivesTo investigate the changes of hepatocellular carcinoma cell line SMMC-7721 in cell ultrastructure and skeleton during apoptosis induced by Survivin ASODN.MethodsSurvivin ASODN was transfected into SMMC-7721 cells mediated by DOTAP liposomal reagent. The changes of Survivin protein and mRNA expression after transfection were assessed by Western blot and in situ hybridization. The apoptotic rate was detected by flow cytometer. Cell ultrastructure and skeleton were observed by electron microscope and confocal microscope. Caspase-3 was assessed by kinase activity assess method. Results The expression of Survivin protein and mRNA decreased from 69.59 and 75.6 to 10.71 and 22.9 respectively. The cell ultrastructure showed apoptotic changes. Cell skeleton microfilament system changed after Survivin ASODN transfection. The average intensity of microfilament system fluorescent decreased from 190 to 64. The activity of Caspase-3 increased from 0.015 3 to 0.099 2.ConclusionsTransfection of ASODN targeted to Survivin mRNA by DOTAP liposomal transfection reagent down-regulated the expression of Survivin protein and mRNA in SMMC 7721 cell line and activate Caspase-3, which in turns induced cell apoptosis.
ABSTRACT
Purpose:To study the effects on T lymphocyte subtypes with chemical splanchic denervation for patients with pancreatic carcinoma and intractable pain.Methods:32 cases with advanced pancreatic carcinoma accepted chemical splanchic denervation-pure alcohol injection around celiac ganglion guided by B US to relieve the severe pain. The fasting peripheral blood concentration of CD + 3 ,CD + 4 ,CD + 8 and ? endorphin were determined before treatment ,3rd,7th,15th and 30th day after therapy. 38 healthy persons were taken as control group.Results:The percentage of CD + 3 ,CD + 4 ,CD 8+ cell were apparently decreased in patients with pancreatic carcinoma comparing with control group( P
