Objective:To investigate the use of simple pooling and bivariate model in meta-analyses of diagnostic test accuracy (DTA) published in Chinese journals (January to November, 2014), compare the differences of results from these two models, and explore the impact of between-study variability of sensitivity and specificity on the differences. Methods:DTA meta-analyses were searched through Chi-nese Biomedical Literature Database (January to November, 2014). Details in models and data for four-fold table were extracted. Descriptive analysis was conducted to investigate the prevalence of the use of simple pooling method and bivariate model in the included literature. Data were re-analyzed with the two models respectively. Differences in the results were examined by Wilcoxon signed rank test. How the re-sults differences were affected by between-study variability of sensitivity and specificity, expressed by I2 , was explored. Results:The 55 systematic reviews, containing 58 DTA meta-analyses, were included and 25 DTA meta-analyses were eligible for re-analysis. Simple pooling was used in 50 (90. 9%) systematic reviews and bivariate model in 1 (1. 8%). The remaining 4 (7. 3%) articles used other models pooling sensitivity and specificity or pooled neither of them. Of the reviews simply pooling sensitivity and specificity, 41(82. 0%) were at the risk of wrongly using Meta-disc software. The differences in medians of sensitivity and specificity between two models were both 0. 011( P<0. 001, P=0. 031 respectively). Greater differences could be found as I2 of sensitivity or specificity became larger, especially when I2 >75%. Conclusion:Most DTA meta-analyses published in Chinese journals(January to November, 2014) combine the sensitivity and specificity by simple pooling. Meta-disc software can pool the sensitivity and specificity only through fixed-effect model, but a high proportion of authors think it can implement random-effect model. Simple pooling tends to underestimate the results compared with bivariate model. The greater the between-study variance is, the more likely the simple pooling has larger deviation. It is necessary to increase the knowledge level of statistical methods and software for meta-analyses of DTA data.

Objective To evaluate the role of Restriction fragment length polymorphism (RFLP) analysis in detection of the fragment of GEF1α/a gene which are both located at ct and a mating type loci in identification of species, varieties, genotypes and mating types of Cryptococcus neoformans species complex(Cryptococcus neoformans and Cryptococcus gattii). Methods The GEF1α/a gene was selected from 20 genes which both located at α and a mating type loci for RFLP analysis, according to the requirements of sequence similarities and primer design in PCR-RFLP analysis. Primer pair was designed from the conserved regions of GEF1α/a genes of distinct genotypes and mating types of reference strains to amplify a fragment of GEF1α/a gene from Cryptococcus neoformans and Cryptococcns gattii strains tested. Sequence alignment,restriction maps analysis, endonucleases selection and electrophoresis stimulation were conducted by using DNAMAN and Vector NTI software. EeoT14 Ⅰ and Hap Ⅱ endonucleases were selected for RFLP analysis of the GEF1α/a fragments amplified from 125 isolates of Cryptococcns neoformans and Cryptococcus gattii. Results An approximate 1 300 bp fragment was amplified from total 82 Cryptococcus neoformans and 43 Cryptoceccus gattii isolates. However, negative PCR results were found in the reference strains of Cryptococcus laurentii, Candida albicans, Candida tropicalis, Candida parapsilosis, Candida krnsei,Candida glabrata, Trichosporon asahii, Aspergillus fumigatns and Aspergillus flavus. RFLP analysis successfully identified the species, varieties, genotypes and mating types of total 125 isolates of Cryptococcus neoformans and Cryptococcns gattii tested in this study. Condusion PCR-RFLP analysis of the GEF1α/a fragment has the potential value in identification of species, varieties, genotypes and mating types of Cryptococeus neoformans species complex simultaneously and rapidly, and may be a useful tool in molecular epidemiological analysis.

Objective:To systematically review the effects of glucagon-like peptide-1 receptor agonists (GLP-1 RAs)on two common respiratory system adverse events (RSAE:nasopharyngitis and upper re-spiratory tract infection)among type 2 diabetes (T2DM).Methods:Medline,Embase,Clinical trials and Cochrane library were searched from inception through May 201 5 to identify randomized clinical trials (RCTs)assessed safety of GLP-1 RAs versus placebo or other anti-diabetic drugs in T2DM.Network meta-analysis within a Bayesian framework was performed to calculate odds ratios for the incidence of RSAE.Results:In the study,50 RCTs were included,including 1 3 treatments:7 GLP-1 RAs (exenati-de,exenatide-long-release-agent,liraglutide,lixisenatide,taspoglutide,albiglutide and dulaglutide), placebo and 5 traditional anti-diabetic drugs(insulin,metformin,sulfonylureas,sitagliptin and thiazo-lidinediones ketones).Compared with insulin,taspoglutide significantly decreased the incidence of naso-pharyngitis (OR =0.67,95%CI:0.46 -0.96).Significant lowering effects on upper respiratory tract infection were found when taspoglutide versus placebo (OR =0.57,95%CI:0.34 -0.99)and insulin (OR =0.39,95%CI:0.23 -0.73).The result from the network meta-analysis based on Bayesian theo-ry could be used to rank all the treatments included,which showed that taspoglutide ranked last with mi-nimum risk on nasopharyngitis and upper respiratory tract infection.Conclusion:Taspoglutide was associ-ated with significantly lowering effect on RSAE.
