In recent years,combined therapy based on radical resection has promoted the prognosis of gastric cancer,but the rate rate of post-surgery recurrence is still high,which is the main cause of death.It helps us take out better treatment for gastric cancer to analyze correlation factors of gastric cancer recurrence after radical resection.It is needed to reviewed the literatures about correlation factors analysis of gastric cancer recurrence after radical resection in recent years.

BACKGROUND:For patients with osteoporosis, bone mineral density and other factors can lower the success rate of posterior lumbar interbody fusion. But there is no comprehensive report on the effects of different bone graft materials and osteoporosis on the posterior lumbar interbody fusion.
OBJECTIVE:To explore the influence of different bone graft materials and osteoporosis on the success rate of posterior lumbar interbody fusion.
METHODS:Clinical data of 227 patients undergoing posterior lumbar interbody fusion were retrospectively analyzed, and these patients were assigned into autogenous iliac bone group (n=121), fusion cage combined with autogenous cancelous bone group (combined group,n=65) and alograft group (n=41) according to different bone graft materials. There were 20, 22, 6 patients with osteoporosis in the three groups, respectively. Al the patients were folowed up for 24 months, and postoperative bone fusion, fusion time, intervertebral height and internal fixation failure and other adverse events were recorded and compared among three groups.
RESULTS AND CONCLUSION:The failure rate of internal fixation, fusion time and loss of intervertebral height were higher, but the fusion rate was lower in the alograft group than the other two groups (P < 0.05). In addition, there was no difference between the autogenous iliac bone group and combined group. For the osteoporosis patients, the failure rate of internal fixation and fusion time were higher, while the loss of intervertebral height and fusion ratewere lower in the alograft group than the other two groups (P < 0.05); compared with the autogenous iliac bone group, the combined group had longer fusion time and higher fusion rate (P < 0.05). These findings indicate that autogenous iliac bone graft combined with or without fusion cage can achieve higher fusion rate and less internal fixation failure in the posterior lumbar interbody fusion; however, for osteoporosis patient, the autogenous iliac bone graft can obtain better fusion effects.

Objective To assess the risks of complications of loop colostomy and loop ileostomy.Methods The databases of Medline,Embase,Cochrane Library,Google Scholar and Wanfang were retrieved to identify the published studies comparing the advantages between loop colostomy and loop ileostomy.All the articles retrieved were published before April 15,2011.The incidence of complications was analyzed by Meta-analysis.The data were analyzed by the Z test and the heterogeneity of the data was analyzed by the Q test.Results Five randomized controlled trials and 8 non-randomized controlled trials with 1752 cases were included in the Meta-analysis.Compared with loop ileostomy,loop colostomy was associated with significantly increased risk of stoma prolapse ( OR =3.46,95％ CI:1.81-6.63,P ＜ 0.05 ).There were no significant differences in the incidences of stoma hemorrhage and stenosis,wound infection,stoma necrosis,parastoma dermatitis and hernia between patients who received loop ileostomy and those who received loop colostomy.Compared with loop ileostomy,loop colostomy was associated with increased risk of wound infection following stoma closure(OR =3.44,95％ CI:1.95-6.05,P ＜0.05).Compared with loop colostomy,loop ileostomy was associated with increased risk of postoperative bowel obstruction following stoma closure(OR =0.43,95 ％ CI:0.20-0.91,P ＜ 0.05 ).There was no significant difference in the risk of anastomotic leak between loop ileostomy and loop colostomy.Conclusion Compared with loop ileostomy,loop colostomy is associated with increased risk of stoma prolapse and wound infection after stoma closure,while a higher risk of bowel obstruction following stoma closure is observed after loop ileostomy.

Objective To explore the role of Bcl-2 and Caspase-3 in modulating apoptosis of ER-negative breast cancer cells induced by tamoxifen. Methods ER-negative breast cancer cell lines MDA-MB-231 were treated with 10.0?M tamoxifen for 12, 24, 36,48, 60 hours. The rate of cell apoptosis with or without caspase-3 inhibitor Ac-DEVD-CHO, and protein expression of Bcl-2,Bax were determined by flow cytometry, and the activity of Caspase-3 was examined with fluorophotometry. Results The expression of Bcl-2 was down-regulated, the activity of Caspase-3 and the rate of cell apoptosis were increased by TAM time-dependently, and the rate of apoptosis reached its peak at 48 hours. The expression of Bcl-2 was (negatively) correlated with activity of caspase-3. Tamoxifen, however, did not affect Bax protein expression. Ac-DEVD-CHO, a caspase-3 inhibitor, blocked the activation of caspase-3 and inhibited cell apoptosis (induced) by tamoxifen. Conclusions TAM could induce apoptosis in ER-negative breast cancer cells via (mitochondria) pathway by down-regulating Bcl-2 expression, and the activation of Caspase-3 might play an (important) role in the process of tamoxifen-induced apoptosis of ER-negative breast cancer cells.
