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.

Objectives To investigate the methods of protecting external branch of the superior laryngeal nerve (EBSLN)in carotid endarterectomy and to observe the effect of using these methods in clinical surgery. Methods EBSLN (20 sides)of 10 heads of corpse were studied by using microanatomy from January 2013 to December 2013. The occurrence probability of EBSLN on the lower edge of posterior belly of digastric muscle,medial edge of external carotid artery and upper edge of superior thyroid artery in anatomy triangle was analyzed. The distances from the midpoint of the EBSLN to carotid bifurcation, mandibular angle and mastoid tip were measured. Sixty-five patients with carotid endarterectomy in Tianjin Huanhu Hospital from December 2013 to November 2014 were treated with the protective methods of the relevant EBSLN by using anatomy triangle as a mark. Whether the patients had injury symptoms of EBSLN were followed up after procedure. Results (1)The occurrence probability of 20-side EBSLN in anatomy triangle was 95%(19 sides). The midpoint of EBSLN in the anatomy triangle at the posterior mandibular angle was median 0. 34 (-1. 62 to 2. 43)cm,at the inferior mandibular angle was 1. 28 (-1. 33 to 3. 42) cm,at anterior mastoid tip was 2. 84 (0. 51 to 5. 14)cm,at inferior was 4. 51 (2. 82 to 6. 39)cm,and at anterior superior of the carotid bifurcation was 1. 64 (0. 57 to 3. 78)cm. (2)65 patients who underwent carotid endarterectomy used the protective methods of intraoperative EBSLN. There was no manifestation of EBSLN injury at 3 weeks to 9 months after procedure. Conclusion In carotid endarterectomy,taking an anatomic triangle as a symbol,it is no more than 2 cm of the anterior superior of carotid bifurcation during the separation process. As for the patients with higher or lower position of carotid bifurcation,in the range of crossing rear mandibular angle 0. 50 cm or below the mastoid tip 4. 50 cm for arterial separation should be avoided,and this can effectively protect EBSLN.

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 investigate the galectin-3 expression in squamous carcinioma of esophagus and analyze its relationship with clinicopathological characteristics.Methods S-P immunohistochemistry was used to detect the expression of galectin-3 in 80 paraffin-embedded specimens of esophageal carcinoma and 22 specimens of normal tissues adjacent to the benigh lesions of esophagus.RT-PCR was performed to detect galectin-3 mRNA expression in 36 pairs of fresh squamous carcinoma tissues and corresponding adjacent normal mucosa.Results Out of 80 specimens of squamous carcinoma of esophagus,62 specimens had positive expression of galectin-3,with the positive rate of 77.5%(62/80)that was significantly higher than 27.27% in normal esophageal tissues(6/22,P

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.
