METHODS: A case-control investigation including 212 gastric cancer patients and 377 healthy controls was conducted. The genotypes of SNPs (rs6983267, rs7008482 and rs10808555) were examined and established through polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Multivariate logistic regression models were used to evaluate the association between SNPs and gastric cancer. RESULTS: The genotype frequencies of rs6983267 in gastric cancer patients were obviously different from those in the control (P = 0.005). GT genotype of rs6983267 was associated with an increased risk of gastric cancer compared with GG genotype (adjusted odds ratio = 2.01, 95% confidence interval: 1.28-3.14). Further stratified analysis indicated that rs6983267 GT genotype facilitated the risk of gastric cancer of non-cardiac and intestinal type (OR: 2.638, 95% CI: 1.464-4.753; OR: 1.916, 95% CI: 1.166-3.150, respectively). CONCLUSION: This study demonstrates for the first time that rs6983267 is involved in susceptibility to gastric cancer, although further large-sample investigations are still needed.展开更多

Nevertheless, SMEs are facing a lot of problems in the market competition, such as technical backwardness, information lag, lack of talents, etc.. The healthy development of SMEs is very important, whereas, SMEs’ financing is a worldwide problem, and the result of financing game between banks and enterprises depends on a variety of decision-making factors. In this paper, from the point of view of bank, we analyze the diffi culties of external financing of SMEs, and establish a financing game model based on different risk categories, in order to better solve the problems that remain in the process of financing and promote the healthy and sustainable development of SMEs.展开更多

The loan failure has been an important problem that the banking must face and revolve. This paper develops a factor system to explain how the borrower's risk is affected, and then establishes a risk monitoring model with AHP to pre-warn the banks how much the risk is.展开更多

Several in vitro and in vivo studies have proved that antioxidant could act as neuroprotective agent through intervening with flee-radical mediated apoptosis in the ischemic penumbra. In particular, natural products which contain antioxidant properties have undoubtedly potential for stroke treatment. In the present study, therapeutic effects of Braintone on Wistar rats undergone middle cerebral artery occlusion (MCAO) was evaluated. Gene expression levels of pro-apoptotic genes (AT2 receptor, FAS, BAX and BCL-XS) were showed to be significantly reduced in Braintone treated groups (0.4-, 0.72-, 0.76-, 0.32-fold, P〈0.05) as compared to vehicle group. Significant reduction ofimmunoreactivity of protein production of these genes, together with least nuclear green fluorescence observed in TUNEL, Braintone as an antioxidant drug, is concluded to have promising therapeutic effect for stroke treatment.展开更多

METHODS: A cerebral ischemic stroke model in SD rats was established with the suture-occlusion method. Successful model rats were divided into placebo and herb groups at random; sham-operat- ed and control groups were set up simultaneously.Each of these groups was divided into six sub- groups at random. Expression of Nogo-A and p75TR was evaluated with immunofluorescence microsco- py at days 3, and weeks1, 2, 3, 4 and 8 after adminis- tration. RESULTS: Tonifying liver and kidney-essence herbs suppressed the expression of Nogo-A and p75T (P〈0.05 and P〈0.01, respectively). CONCLUSION: Suppressing the expression of No- go-A and p75NTR is possibly one of the mechanisms underlying the ability of tonifying liver and kid- ney-essence herbs to promote recovery of the in- jured central nervous system.展开更多
