Patients with advanced gastric cancer lose the surgical indications.Chemotherapy can improve the overall survival and quality of life,which is the main treatment option.But there is no standard chemotherapy regimen for the patients with advanced gastric cancer.Since its initial approval,S-1 is widely used in gastric cancer.Several studies were performed to explore combinations of S-1 with other cytotoxic drugs such as platinum,docetaxel,paclitaxel,and irinotecan.All these combinations were found to be promising,with response rates of around 40％-50％ and relatively favorable safety profiles.

Objective To explore the oxidative stress pathogenesis of Parkinson's disease(PD) induced by paraquat in substantia nigra of mice. Methods The model of PD was established by oral administration of paraquat to mice.The spectrophotometry was used to determine the activities of superoxide dismutase(SOD) and glutathione peroxidase(GSH-PX) and the content of malondialdehyde(MDA) in substantia nigra.At the same time,number of tyrosine hydroxylase(TH) positive neurons in substantia nigra of mice was estimated by immunohistochemistry. Results The activities of SOD and GSH-PX were significantly decreased,and the content of MDA was increased in paraquat-treated mice compared to that of mice treated by saline taken orally(P

Objective To explore the effect of meta-mood ability training for improving job satisfaction of nurses.Methods A total of 120 nurses were randomized into the observation group and the control group (60 cases in each group).The observation group received meta-mood ability training,while the control group was given routine training.The meta-mood ability and job satisfaction degree were investigated.Results After the intervention,job satisfaction degree and the meta-mood ability level of the observation group nurses were improved than that of the control group.Conclusions The meta-mood ability training is effective in improvement of job satisfaction degree of nurses,as well as increase clinical service quality of nurses.

Objective To generate the spaO-ompA fusion gene of Salmonella paratyphi A and its prokaryotic expression system,and to determine the immunoprotection of the recombinant expression product rSpaO-OmpA.Methods A flexible peptide sequence was used to link spaO and ompA genes and a prokaryotic expression system of spaO-ompA fusion gene was subsequently generated.SDS-PAGE and Bio-Rad Agarose Image Analyzer were applied to examine the expression as well as the yield of the target recombinant protein rSpaO-OmpA.The antigenicity and immunoreactivity of rSpaO-OmpA were determined using immunodiffusion test,Western Blot assay and micro-Widal's test.By a mouse infection model,the immunoprotection of rSpaO-OmpA against the lethal challenge of S.paratyphi A was determined.In the animal protective test,the recombinant expressed SpaO (rSpaO) and OmpA ( rOmpA ) were used as the controls.Results The generated spaO-ompA fusion gene had 100％ nucleotide and amino acid sequence identities compared to the single spaO or ompA gene.The constructed prokaryotic expression system IPTG E.coli BL21DE3pET42a-spaO-ompA expressed the recombinant protein rSpaO-OmpA.rSpaO-OmpA combined with the antiserum against wholecell of S.paratyphi A to present positive hybridization signal and induced specific antibody in the immunized rabbits.Immunization with 100 or 200 μg rSpaO-OmpA contributed 66.7％ (8/12) or 83.3％ (10/12) immunoprotective rates in mice when the animals were attacked with S.paratyphi A.The immunoprotective rates produced by rSpaO-OmpA were significantly higher than that of equal rSpaO or rOmpA( P＜0.05 ).The sera from rSpaO-OmpA immunized mice presented 1∶5-1∶40 agglutination titers to the H antigens of different S.paratyphi species,and 1∶1-1∶16 immunodiffusion titers to rSpaO,rOmpA and rSpaO-OmpA proteins,respectively.Conclusion The artificially fusion antigen,rSpaO-OmpA,has more powerful immunogenicity and immunoprotection that the equal rSpaO or rOmpA.
