Objective To investigate the gene-expression profile in kidney of rats during late sepsis (24hours) by using microarray technology in order to offer some clue to revealing the pathogenetic mechanism of sepsis at gene level. Method A total of 30 Wistar rats were selected and divided into model group and control group randomly(random number). The rats of control group were sham operated and the rats of model group received cecal ligature and puncture (CLP) operation. The biomarkers of renal function were assayed and the histopathological changes of kidney in rats were observed under transmission electron microscope 24 hours after operation. Gene chips containing 22 107 rat-genes cDNA were used to exmine gene-expression in kidney of septic rats to sieve the genes with different expressions with software. Data were analyzed by using SPSS version 11.0 software package.Statistical analyses of two independent samples carried out by using t -test. Results Compared with the control group, the levels of blood urea nitrogen (BUN) and creatinine (Cr) of sepsis group were higher (P ＜ 0.01 ). The histopathological changes in kidney of rats demonstrated the establishment of sepsis model successful 24 hours later.Compared with the control group, there were 325 genes with differential expression in model group. Among the known-functional genes, there were 100 up-regulated and 64 down-regulated. Sorted by biological function, the genes were mainly related to metabolism, immunoresponse, cellular signal transduction, apoptosis, ion channel,growth factor and so on. Conclusions A sequence of genes expressed differentially in kidney of rats with late sepsis. Microarray technology played an important role in the research into sepsis mechanisms.

Objective To discuss the distributions and drug resistance of gram-positive cocci and provide scientific basis for reasonable use of antimicrobial drugs.Methods One hundred and twenty-five strains were isolated and cultured in our department from January 2009 to December 2011.The drug susceptibility was tested by K-B method and the results were judged by the criteria guideline of CLSI 2009.Results The main strains of separated cocci were Staphylococcus aureus (68,54.4％),Enterococcus faecium (22,17.6％),coagulase-negative staphylococcus (CNS) (20,16.0％),Enterococcus faecalis (6,4.8％),Staphylococcus haemolyticus(7,5.6％)and other gram-positive cocci (2,1.6％).Methicillin-resistant S.aureus (MRSA) and Methicillin-susceptible S.aureus (MSSA) detected were 40 and 28 strains(accounted for 58.8％ and 41.1％ of S.aureaus).The results of drug susceptibility tests showed that the drug resistant rate of MRSA to Gentamicin,Clidamycin,Erythromycin and Ciprofloxacin was up to 87.5％-95.0％,and the drug resistant rate of coagulasenegative staphylococcus to Penicillin,Erythromycin,Clidamycin and Gentamicin was up to 65.0％-95.0％,besides,the drug resistant rate of E.faecalis and E.faecium to Erythromycin,high level Gentamicin and Ciprofloxacin were 86.4％-100％ and 50.0％-66.7％,respectively.No strains with drug resistant to Vancomycin,Teicoplanin and Linezolid were detected.Conclusion S.aureus was the main strains of nosocomial infection of gram cocci.The resistance of gram-positive cocci is severe,so clinicians should attaches great importance to high drug resistance of gram-positive cocci.

Objective To investigate the efficacy of scalp acupuncture plus moxibustion in treating post-stroke should hand syndrome. Method Seventy-three patients were divided into two groups. the treatment group of 42 patients received scalp acupuncture plus moxibustion and the control group, conventional acupuncture.
