Objective To explore time difference attack therapy in Acinetobacter bauamnnii infection. Methods 67 patients with Acinetobacter bauamnnii were divided into two groups. The experimental group were first given Fosfomycin 4 g 5% GS 100 ml iv girt to finish within 60 min and then given Cefperazone/Sulbactam 4 g 0.9% NS 250 ml iv gitt immediately bid. The control group were given: Ampicillin/Sulbactam 3 g 0.9% NS 250 ml iv gitt (tid) + Ciprofloxacin 0.2 g iv girt (bid). The treatment course all was 11 days. Results The overall effective rate of experimental group methods was superior to that of control group(X2 =9.56 ,P =0. 023). Conclusion The Fos-fomycin Cefperazone/Sulbactam time difference attack therapy for the treatment of Acinetobacter the bauamnnii in-fection is a new way.

Objective To evaluate the usefulness of DiversiLab system for genotyping of Acinetobacter baumannii.Methods Fifty-eight non-duplicated clinical Acinetobacter baumannii isolated from 15 cities in China in 2005 were typed by rep-PCR-based DiversiLab system.The results were compared with those of PFGE and multilocus sequence typing. Simpson's index of diversity was used to compare the discriminatory power among DiversiLab system, PFGE and MLST.Results Fifty-eight Acinetobacter baumannii isolates were differentiated into 5 clusters and 25 unique types by DiversiLab system. MLST identified 35 distinct sequence types, which fell into one clone complex of CC22 and 35 singletons, while PFGE resolved 5 pulsotypes and 34 unique types.Simpson's diversity indices for DiversiLab system, MLST and PFGE were O.876, O.944 and 0.961, respectively.Conclusions The discriminatory power of DiversiLab system is lower than that of PFGE and MLST.But as a simple, fast and reproducible typing method, it could be used as a first-line typing tool for the analysis of a large number of isolates.

Objective To explore quality of life and coping style of autistic children' s parents, and correlation between them. Methods 68 parents of children with autism and 64 healthy children' s parents were tested with comprehensive assessment questionnaire of the quality of life and coping style questionnaire. Data were analyzed by t -test and multivariate regression analysis. Results The scores of material life and mental health dimensions in study group(48.18 ± 12.80,60.63 ± 10.18 ) were lower than that in control group(52.71±9.84,65.79±8.64) and the difference was significant( t= -2.04, P＜0.05; t= -3.09, P＜0.01 ). The scores of "problem solving" coping style in study group were slower than in control group; the scores of fantasy and wincing coping style in study group were higher than that in control group. By multivariate regression analysis showed that the scores of "problem solving" coping style were positively correlated with total score of life quality,physical health,mental health and social function dimensions; the scores of "fantasy" coping style had negative correlation with the total score of life quality; the scores of "wincing" coping style had negative correlation with mental health dimension. Conclusion Parents of autistic children were more susceptible to problems of physical life and mental health. Compared to parents of normal children they are more in "fantasy and wineing style and less in" problem solving style to cope with stress, so it would affect the quality of life and mental health badly and need early intervention.

Objective To investigate the molecular epidemiology of carbapenem resistant Acinetobacter baumannii from Zhejiang Province using multilocus sequence typing.Methods Three hundred and two imipenem or meropenem resistant A.baumannii isolates were collected from eleven tertiary hospitals of eleven different regions of Zhejiang Province in 2009 and 2010.Multilocus sequence typing was used for molecular typing.eBURST was used to analyze the results of multilocus sequence typing.PCR was used to detect the OXA-type carbapenemase genes.Results Seventeen sequence types (STs) were identified from three hundred and two A.baumannii isolates.eBURST analysis revealed eleven STs belonged to clonal complex 92 (CC92) and corresponded to European clone Ⅱ lineage.CC92 was the predominant carbapenem resistant A.baumannii clone of Zhejiang Province,which accounted for 94.4％ (285/302) of all isolates and distributed in all 11 hospitals.blaOXA-23 gene was identified in 97.4％ (294/302) of all isolates.Conclusions Carbapenem resistant A.baumannii CC92 were clonal disseminated among multiple hospitals of Zhejiang Province.blaOXA-23 was the most popular carbapenemase gene in carbapenem resistant A.baumannii.(Chin J Lab Med,2013,36:303-307)

OBJECTIVETo observe the effects of electroacupuncture (EA) at different acupoints on apoptosis-related serum and expression of microRNA (miRNA) in rats with myocardial ischemia, so as to explore its mechanism of action.

METHODSA total of 48 male Wistar rats were randomly divided into a normal group, a model group, a Neiguan group and a acupoint compatibility group, 12 rats in each group. Isoprenaline hydrochloride (ISO) with a daily dose of 2 mg/kg was subcutaneously injected for 14 days to establish the myocardial ischemia model in the model group, Neiguan group and acupoint compatibility group. Rats in the normal group were subcutaneously injected with an equal volume of normal saline. After modeling, rats in the Neiguan group were treated with EA at "Neiguan" (PC 6), while rats in the acupoint compatibility group were treated with EA at "Guanyuan" (CV 4), "Zusanli" (ST 36) and "Neiguan" (PC 6). Rats in the normal group and model group were treated with immobilization, once day for 21 days. The contents of creatine kinase-MB (CK-MB), vascular cell adhesion molecule-1 (VCAM-1) and endothelin-1 (ET-1) in serum were detected by enzyme-linked immunosorbent assay (ELISA); apoptosis index (AI) of myocardial cells was detected by TUNEL method; the expressions of miRNA-1, miRNA-133, miRNA-208 and miRNA-499 were detected by real-time PCR method.

RESULTSCompared with the normal group, the serum CK-MB, VCAM-1 and ET-1 were significantly increased in the model group, Neiguan group and acupoint compatibility group (all P < 0.01), and the apoptosis index was significantly increased (all P < 0.01). The CK-MB, VCAM-1 and ET-1 in the Neiguan group and acupoint compatibility group were significantly lower than those in the model group (all P < 0.01); the AI was reduced, which was more significant in the acupoint compatibility group (P < 0.05). Compared with the normal group, the expression of miRNA-133 was reduced (P < 0.01) and those of miRNA-208, miRNA-1 and miRNA-499 were significantly increased in the model group (all P < 0.01). Compared with the model group, the expression of miRNA-133 was increased (both P < 0.01) and that of miRNA-208, miRNA-1 and miRNA-499 were significantly reduced (all P < 0.01) in the Neiguan group and acupoint compatibility group. Compared with the Neiguan group, the expression of miRNA-133 was increased (P < 0.01) and those of miRNA-208, miRNA-1 and miRNA-499 were significantly reduced in the acupoint compatibility group (P < 0.01, P < 0.05).

CONCLUSIONEA at acupoints, especially acupoint compatibility group, could effectively prevent and treat myocardial ischemia, and the protective effect is possibly correlated to the double regulation on increasing the expression of miRNA-133 and inhibiting the expression of miRNA-1, miRNA-208, miRNA-499.
