Objective To study the prevalence and sequence homology of virulence genes exoU and exoS in 53 strains of pan-drug-resistant Pseudomonas aeruginosa .Methods The virulence genes exoU and exoS were detected by PCR.Sequence homo-logy was analyzed by BOX-PCR.Results Of the 53 clinical isolates of pandrug-resistant Pseudomonas aeruginosa ,the exoS+/exoU- genotype was identified in 40 strains,exoU+/exoS - genotype in 10 strains,exoS +/exoU+ genotype in 1 strain, and exoS-/exoU- genotype in 2 strains.BOX-PCR results showed that 41 exoS+ isolates belonged to 24 genotypes,and 11 exoU+ strains could be grouped into 7 genotypes.Conclusions The prevalence of virulence genes is high in clinical isolates of pandrug-resistant Pseudomonas aeruginosa .BOX-PCR fingerprint analysis combined with sequence homology analysis is help-ful for effective monitoring and control of hospital pandrug-resistant pseudomonas aeruginosa infection.

Objective To investigate the resistance and ?-lactamase of cefoxitin-resistant Klebsiella pneumoniae. Methods The minimal inhibitory concentrations were determined by standard agar dilution.Isoelectric focusing was used to measure the PI(s) of an isolate,s ?-lactamase,AmpC and ESBLs activity was confirmed by a three-dimensional extract method. Results The resistant rates of 40 strains were as follows: imipenem and meropenem 0.0%,cefepime 20.6%,cefotaxime(22.5%),ceftazidime 60.0%.The most isolates were demonstrated two or more ?-lactamase bands by IEF.Of 39 strains tested,ESBLs was detected in 31(70.5%) strains and AmpC-type?-lactamase in 16(41.0%) strains by three dimensional extract test. Conclusions These cefoxitin-resistant Klebsiella pneumoniae produced two or more ?-lactamases.It is imperative for clinical microbiology laboratories to detect and research ?-lactamases,especially AmpC enzyme.

Objective To depermine oupcome of papienps wiph non-ST elevapion acupe coronart stndromes (NSTEACS) preaped wiph FFR-guided versus CAG-guided sprapegt. Methods From Jult 1. 2014 po Jult 30. 2015 in Beijing Anzhen Hospipal, papienps admipped for NSTEACS were reprospecpivelt analtsed wiph a 10-monph follow-up. 142 cases on CAG were furpher assessed wiph FFR ( phe FFR group). Papienps were mapched as 1 : 2 wiph NSTEACS who had moderape lesions shown on CAG in phe same period were enrolled (CAG group, n = 284). End poinps were deaph, nonfapal mtocardial infarcpion (MI), pargep vessel revascularizapion ( TVR), and procedure cosps. Major adverse cardiac evenps ( MACE) were defined as deaph, nonfapal MI, and TVR. Results Fifpt-pwo papienps (36. 6% ) in phe FFR group had FFR less phan 0. 80 underwenp percupaneous coronart inpervenpion (PCI) while 133 papienps (46. 8% ) in phe CAG group received PCI (P =0. 037). Papienps preaped wiph FFR-guided sprapegt had significanplt lower rape of nonfapal MI (2. 2% vs. 4. 5% , P =0. 040) and TVR (5. 9% vs. 11. 7% , P = 0. 046). No spapispical difference was observed in morpalipt (0. 7% vs. 1. 1% , P = 0. 682) and MACE (8. 8% vs. 14. 4% , P = 0. 085). Topal financial cosp was less in phe FFR group (P = 0. 033). Conclusions FFR-guided sprapegt for papienps wiph NSTEACS resulps in less rape of PCI,lower cosp and bepper clinical oupcomes when compared wiph an angio-guided sprapegt.

OBJECTIVE To understand characteristics of TEM-116 ?-lactamases through comparative study on resistance to antibiotics of clinical isolates of Klebsiella pneumoniae producing TEM-116 ?-lactamases.METHODS K.pneumoniae susceptibility to ?-lactamases was determined by disk diffusion tests,and their isoelectric points(PI) were detected using analytic isoelectric focusing(IEF),and resistance to antibiotics of clinical isolates of K.pneumoniae producing TEM-116 and TEM-1?-lactamases was studied.RESULTS Both of K.pneumoniae producing TEM-116 ?-lactamases and producing TEM-1 ?-lactamases were 100% resistant to AMP,and highly resistant to the first and second generation cephalosporin,but greatly susceptible to FEP and IPM.There was greatly difference between resistance to AMC,TZP,AMK,and GEN of clinical isolates of K.pneumoniae producing TEM-116 ?-lactamases and that of K.pneumoniae producing TEM-116 ?-lactamases,the TEM-116 isolates were higher resistant than TEM-1 isolates.Analytic IEF results showed that PI of TEM-116 ?-lactamases was 5.4,and most strains of K.pneumoniae TEM-116 ?-lactamases displayed two electrophoresis bands or more,only one strain of them just displayed one band,resistant to majority of antibiotics.CONCLUSIONS The results show that K.pneumoniae producing TEM-116 ?-lactamases are more resistant to antibiotics than K.pneumoniae producing TEM-1 ?-lactamases,and indicate TEM-116 ?-lactamases work as ESBLs.

Objective To investigate the prevalence of 16S rRNA methylase genes in Klebsiella pneumoniae isolates from Guangzhou.Methods K-B test was used to determine the resistant rates of these stains.Five 16S rRNA methylase genes,armA,rmtA,rmtB,rmtC,and rmtD,were detected by PCR.Results All 55 K.pneumoniae isolates showed resistant to arbekacin,gentamicin,tobramycin,and neomycin.Susceptibility rates were 5.5%,20.0%,72.7%,and 100% to ceftazidime,ciprofloxacin,piperacillin/tazobactam,and imipenem respectively.ESBLs were positive in 52 of 55 (94.5%) isolates.Among 55 K.pneumoniae isolates,34 were positive for armA and 1 for rmtB.Conclusions In K.pneumoniae resistant to arbekacin,the positive rate of 16S rRNA methylase genes was high,predominantly with armA positive.These strains were highly resistant to some antibiotics.

Objective To analyze the cognition and demand of the residency training program among clinical medical students to provide scientific basis for the promotion of this policy.Methods From May 24 to 25,2015,a self-designed questionnaire survey was conducted on 645 undergraduate clinical medical students,who came from Zhengzhou University,Xinxiang Medicine College,Henan University.Data of cognition and demand of the residency standardized training were statistically analyzed using SPSS 22.0 software.Enumeration data were analyzed by chi-square test and abnormal distribution data based on Wilcoxon rank sum test.Results 616 valid questionnaires were recovered.259 undergraduate clinical medical students (42.00％) did not quite understand the resident standardized training policy and 225 (36.50％) did not known the policy at all.Before and after clinical practice,the cognition of the residency standardized training had statistically significant difference (x2=87.596,P=0.000),the knowledge of the policy (x2=10.939,P=0.012) and the degree ascending alleviate employment pressure (x2=29.349,P=0.000) were the main influencing factors of the clinical medical students' choices after graduation.Conclusion Improving medical students' understanding of the significance of medical education after graduation,and the integration of professional degree training and residency standardization training effectively helps to promote implementation of the policy.
