ObjectiveTo verify the relation between the infection of Hp strains with cag A gene and the occurrence of gastric cancer.MethodsThis study included 36 chronic superficial gastritis samples and 30 gastric cancer samples. Diagnosis was made by the endoscopic biopsy, laparotomy, and pathology. Cag A gene was determined by PCR technique.ResultsTotal cag A gene positive rate in chronic superficial gastritis group was 33%,and 80% in gastric cancer group ( P

Inflammation response is the most crucial link in the pathogeneses of spinal cord injury (SCI),and is the basis of secondary damage. NF-κB Signalling pathway is activated excessively after SCI,so that numerous NF-κB possessing biological activities is quickly translocated into the nuclear and regulates the target genes,resulting in heightened inflammation and further tissue damage. Suppressing NF-κB signalling pathway and controlling inflammation response effectively are effective approaches to promoting SCI repair. It is found that curcumin has multiple target molecules to suppress NF-κB signalling pathway,block the excessive activation of NF-κB and reduce the expression of proinflammation cytokines,which plays an important role in SCI repair. This article discusses NF-κB signalling pathway,the contribution of NF-κB signalling pathway to SCI and the role of curcumins inhibition of NF-κB signalling pathway in SCI.

Objective To determine the length of warm ischemic (WI) tolerance in bronchial graft from non-heart-beating donors. Methods Forty-eight rats were randomly divided into 4 groups (each group having 12 rats) according to different WI durations including WI-0 min (group A), WI-30 min (group B), WI-45 min (group C) and WI-60 min (group D). In each group, the tracheae from 6 rats were respectively imbedded in greater omentum of other 6 rats, and 14 days later, the transplanted tracheae were taken from recipients to evaluate epithelial thickness and regeneration. Results Epithelial thickness and the degree of epithelial regeneration had no significant difference (P >0. 05) between the syngeneic control group and the WI-30 minutes group. All of the grafts with WI duration of 45 min were viable, but the epithelium was significantly thinner than that in the syngeneic control group (P<0. 05). However all of the grafts with WI duration of 60 min showed lower viability rate. Conclusion The time limits of tolerance to WI of tracheal grafts from NHBDs may be 45 min.

OBJECTIVETo evaluate the effect of early enteral nutrition(EEN) on immune response and clinical outcomes after esophageal cancer operation.
METHODSSixty patients with esophageal cancer undergoing radical operation between March 2010 and July 2011 were randomly divided into two groups using envelope method: EEN group(n=30, administration of water and enteral nutrition early after operation) and TPN group(n=30, administration of total parenteral nutrition). Two groups both received 7-day nutrition support. Immune indexes(CD3(+), CD4(+), CD8(+), CD4(+)/CD8(+)) and serum nutritional indexes(albumin, pre-albumin, transferrin) were measured before operation and 1-, 3-, and 7-day after operation. The time to first flatus, length of postoperative hospital stay, total hospitalization cost, and postoperative complication were recorded.
RESULTSAs compared to TPN group, the time to first flatus was significantly shorter in EEN group[(66.5±7.3) h vs. (75.1±6.8) h, P<0.01], as was hospital stay[(7.8±1.1) d vs. (9.3±1.3) d, P<0.01]. Total hospitalization cost[(36 210±3810) yuan vs. (39 731±4013) yuan, P<0.01] was lower in EEN group as compared to TPN group. There was no significant difference in postoperative complication rate between the two groups[13.3%(3/30) vs. 20.0%(6/30), P>0.05]. The levels of CD3(+), CD4(+), CD4(+)/CD8(+), albumin, prealbumin and transferrin were significantly higher in EEN group as compared to TPN group on postoperative day 3 and 7(all P<0.05), while CD8(+) was significantly lower in EEN group(P<0.05).
CONCLUSIONEEN can promote early recovery of gastrointestinal function, improve nutritional and immune function, and therefore lead to fast postoperative recovery in esophageal cancer patients.
