Objective To investigate gut barrier dysfunction and bacterial translocation (BT) from gastrointestinal tract in postoperative patients using polymerase chain reaction (PCR) and plasma D-lactate measurement, and to study the relationship between BT and infections complications. Methods 34 patients undergoing selective gastrointestinal operations were observed. Blood samples were collected prior to and 2, 24, 48 h after surgery for bacterial culture, plasma D-lactate, and LPS measurement. PCR was used to detect microbial DNA. PCR was performed after DNA extraction, with target ?-lactosidase gene of E. coli and 16S rRNA gene of most pathogenic bacteria. All the patients were observed for 30 days for monitoring infectious complications. Results No bacterial DNA was detected before surgery, but it was positive in 7 patients (20.6%) after operation. Bacterial DNA was discovered in 38.9% (7/18) of SIRS (systemic inflammatory response syndrome) patients, no bacterial DNA was detected in the 16 non-SIRS patients (P

Objective To express Schistosoma japonicum Mago nashi(SjMago)gene,and prepare its specific polyclonal antibody.Methods SjMago gene was amplified by PCR from Schistosomulum cDNA library and subcloned into pET28a(+)vector,its recombinant proteins were expressed with IPTG.Rabbits were immunized with the polyacrylamide gel particles containing the recombinant proteins for polyclonal antibody preparation,the sera were detected for antibody specificity by Western blot and titer by ELISA assay.Results SjMago prokaryotic expression plasmid was successfully recombined and the target proteins was induced by IPTG in a molecular weight of 17 X 103,the high titer(1∶40 960)polyclonal antibody was isolated from the immunized rabbit,specific rotein band was detected by Western blot.Conclusion SjMago protein has been successfully expressed and its specific polyantibody is prepared,which lays the foundation for further study.

Objective To study the epidemiological characteristics of diabetes mellitus and to provide effective prevention and intervention methods in rural area in Kunming.Methods A cross-sectional study was conducted among 3 440 permanent residents aged 20~74 years in kunming rural districts.Results The general prevalence rate of diabetes was 4.01% and the standardized rate was 2.90%.The standardized prevalent rate for male(3.55%) was higher than that for female(2.61%),and the prevalence rates varied among different groups of rural inhabitants.Conclusion It is necessary to take effective methods to prevent and control diabetes in rural area.

In Alzheimer's disease there is obvious evidence of insulin resistance in the brain. Thiazolidinediones,a kind of insulin sensitizer,not only improves insulin sensitivity,but also decreases inflammation,promotes release and clearance of?-amyloid protein,all are beneficial to the improvement of memory.

Objective To analyze the distribution and drug resistance characteristics of pathogenic bacteria isolated from blood cultures in the infected patients in our hospital during 2009-2013 to provide the newest evidence for the clinical anti-infection ther-apy.Methods The bacterial identification and drug susceptibility test were performed by applying the VITEK-32 System.The dis-tribution situation and the drug susceptibility test results of pathogens isolated from blood culture specimens in our hospital during this period were analyzed.Results 2 301 strains of positive bacteria were isolated from 14 006 cases of blood culture during these five consecutive years.The positive rate was 16.4%.Among them,1 303 strains were Gram positive bacteria(56.6%),954 strains of Gram negative bacilli(41.5%)and 44 strains of fungi(1.9%).Gram-positive bacteria were mainly Staphylococcus aureus,coagu-lase negative staphylococci(CNS),etc.Gram-negative bacteria were mainly E.coli,Klebsiella pneumoniae,etc.E.coli and Klebsiella pneumoniae were highly sensitive to carbapenem,amikacin,cefoxitin and antibacterial drugs containing enzyme inhibitor.The detec-tion rates of extended-spectrumβ-lactamase(ESBL)-producing Escherichia coli and Klebsiella pneumoniae were 55.8% and 18.4%respectively.Acinetobacter baumannii in blood culture had serious resistance to most of antibacterial drugs.Conclusion The kinds of pathogens isolated from blood culture are complex with different sensitivity to antibacterial drugs.Timely understanding the re-sults of blood culture has the important significance to adjust the treatment scheme in clinic and timely discover drug-resistant strains for serve clinic better.
