Objective To evaluate the accuracy of CHROMagar Candida medium in identifying common Candida species .Meth‐ods Articles were extensively collected by searching the databases of MEDLINE and EMBase ,the Chinese Biomedical Database (CBM ) ,the Chinese Scientific Journals Database (CSJD) ,the Chinese Journal Full Text Database (CJFD) and through other ways . The qualities of these articles were assessed by using the quality assessment of diagnostic accuracy studies(QUADAS) .At last , summary receiver operating characteristic (SROC) curve was performed by the Meta‐Disc software ,so as to summarize diagnostic accuracy of CHROMagar Candida medium in identifying common Candida species .Results A total of 7 articles meeting all criteria were enrolled in this study .All 7 articles reported the accuracy of CHROMagar Candida medium in identifying the Candida albi‐cans ,the pooled sensitivity and specificity was 98 .3% and 98 .8% respectively ,and area under SROC curve (AUC) was 0 .998 0 .A‐mong them ,6 articles reported the accuracy of CHROMagar Candida medium in identifying Candida tropicalis ,the pooled sensitivity and specificity was 92 .5% and 99 .8% respectively ,and the AUC was 0 .998 3 .Among them ,5 articles reported the accuracy of CHROMagar Candida medium in identifying Candida Glabrata ,the pooled sensitivity and specificity was 98 .3% and 98 .7% respec‐tively ,and the AUC was 0 .996 8 .Conclusion CHROMagar Candida medium could quickly identify clinical common Candida species and results are reliable .

Objective To investigate the drug resistance of Acinetobacter baumannii strains isolated during 2014 in a hospital of Beijing.Methods Isolated bacteria were cultured by routine method,identified and performed drug susceptibility test by bacteria a-nalysis system.Statistical analysis of Acinetobacter baumannii was conducted by Whonet5.6 software.Results A total of 226 Acin-etobacter baumannii strains were isolated from January 2014 to December 2014 in Fengtai Teaching Hospital of Capital Medical U-niversity.These strains showed the lowest resistance rates to minocycline and Cefoperazone-sulbactam(23.0% and 30.1%).The other antimicrobial resistance rates were more than 50.0%.The resistance rate of Acinetobacter baumannii varied from one depart-ment to another.Pandrug-resistant and multi-drug resistant Acinetobacter baumannii were 71.2%,1 9.0% respectively. Conclusion The resistant rates of Acinetobacter baumannii strains to a variety of antibiotics are high.It is essential to strengthen monitoring the drug resistance of Acinetobacter baumannii,as well as use antibiotics reasonable and separate patients to control Acinetobacter baumannii infection.
