ABSTRACT
Objective To study the protective effects of taurine on liver and kidney injury induced by intestinal ischemia-reperfusion(I/R) in rats.Methods Male Wistar rats were randomly assigned into Sham,I/R,and taurine groups.Thirty min before operation,2% taurine(200 mg/kg) was injected via dorsal vein of the rat′s penis.Intestinal ischemia-reperfusion was produced by occlusion of superior mesenteric artery for one hour later,then the blood flow was restored by removing the clamps.Blood samples were taken from rats in I/R and taurine groups at 1.5,3,6 and 12h after reperfusion,and the serum levels of ALT,AST,BUN and Cr were measured to evaluate the functions of liver and kidney.Tissues from livers and kidneys were cryostated and stained with hematoxylin and eosin to observe changes in histological pathology.TUNEL was also performed to examine apoptotic cells and the average light density levels were measured.Results The serum levels of ALT,AST,BUN and Cr in I/R group were significantly higher than those in Sham group(P
ABSTRACT
Objective To evaluate the clincal therapeutic efficacy of mesh-plug tension-free hernia repair in elder patients with inguinal hernia.Methods The clinical data of 127 elder patients with inguinal hernia treated with mesh-plug tension-free hernia repair in our hospital were analyzed retrospectively.Results All cases were treated by tension-free hernia repair with mesh-plug case-hardened products which manufactured by American Bard Company.All the patients were cured.Average operation time was 40 min,and average(hospital) stay was 4.6d.The patients were followed up for 6~24 months,only 1 case had recurrence of(hernia)(recurrence rate 0.8%).Conclusions Mesh-plug tension-free hernia repair is a perfectly sound physiologic and anatomic operation.It is a simple,minitraumatic procedure,with advantages of quick (recovery),low recurrence rate and wide indications.It is especially suitable to elder patients or patients with the type II or larger hernial.
ABSTRACT
Objective To study the apoptosis-inducing effect of recombinant adeno-associated virus serotype 8 with soluble TRAIL gene on human colon cancer cell line HCT116. Method Recombinant adeno-associated virus serotype 8 with TRAIL gene was generated by triple plasmid transfection of HEK293 cells with phosphate calcium precipitation. After infected by recombinant virus, cell growth assay was carried out by counting alive cells after trypan blue exclusion. Alternations of cell morphology was examined by microscopy. Cell apoptosis was detected by DNA laddering. The protein expressions of apoptosis-3 and apoptosis-8 were detected by Western blotting. Result The growth rate of the AAV8-sTRAIL infected HCT116 cells was significantly inhibited. Recombinant virus induced apoptosis in colon tumor cells by triggering caspase cascade, but not in normal human hepatocytes. Conclusion AAV8-sTRAIL efficiently suppresses the growth of human colon cancer cell line HCT116 by inducing apoptosis, with no evident toxicity to normal cell.
