RESUMO
Objective To investigate the effect of the replication-deficient adenovirus carrying miR-138(Ad-miR138) on the pro-liferation of human gastric cancer cell line BGC-823 and the possible mechanism .Methods The human gastric cancer cell line BGC-823 was infected with Ad-miR138 .Then the expression level of miR-138 was measured by RT-PCR .The growth curve of BGC-823 was measured using CCK-8 method .The ability of cell invasion was measured using Transwell chambers .Results After infected with Ad-miR138 ,the expression of miR-138 in BGC-823 cells was up -regulated significantly (1 .07 ± 0 .07 vs .4 .89 ± 0 .45 ,P<0 .05) .Absorbance of the 6th day decreased significantly (0 .52 ± 0 .06 vs .0 .77 ± 0 .06 ,P<0 .05) ,and the invasion ability was de-creased obviously (32 .00 ± 11 .00 vs .56 .00 ± 12 .00 ,P<0 .05) .Conclusion miR-138 can effectively suppress the proliferation and invasion of human gastric cancer cell line BGC-823 in vitro .
RESUMO
ObjectiveThis study was to evaluate the changes of inflamatory mediators in patients undergoing tension free hernioplasty(LH) using expanded polytetrafluoroethylene (e PTFE) mycromesh biomaterial or conventional Bassini hernia repair(BH). MethodTwenty one patients randomized into two groups receiving LH or BH. Peripheral venous blood samples were collected 24 hours prior to surgery and then 6,24,48 and 168 hours postoperatively.ResultLH patients showed a higher increased serum level of fibringen,C reactive protein,alpha 1 antitrypsin, and interleukin 6 than BH patients. Postoperative visual analogue scales for pain reduced on mobilization for patients undergoing LH compared with BH. Neutrophils significantly increased only in LH compared with baseline. ConclusionOur data show that although LH induces less pain and rapid postoperative recovery,it is associated with an higher inflammatory response compared with BH, likely due to mycromesh biomaterial.
