Objective To assess the diagnostic value of ChromID for Clostridium Clostridium infection (CDI) on the premise of large sample size,with Meta-analysis.Methods The literature inclusion and exclusion standards were made,and the databases were searched,including PubMed,Cochrane Library,China Biology Medicine disc (CBM),China National Knowledge Infrastructure (CNKI) and so on,using the keywords (ChromID,Clostridium difficile,and chromomgenic agar) along with each of the following words (detection,diagnosis,and infection).Quality assessment of diagnostic accuracy studies (QUADAS) was used to evaluate the quality of the literature.The Meta-disc 1.4 software was used to analyze the data.Results Five studies on 1 851 patients were included in this meta-analysis.The pooled sensitivity was 0.793 (95 ％ CI:0.750 ～ 0.832) for the diagnosis of CDI on 48 h,the pooled specificity was 0.942 (95 ％ CI:0.972 ～0.955),the pooled positive likelihood ratio was 16.817 (95％ CI:7.042 ～ 40.157),with negative hkelihood ratio was 0.124 (95％ CI:0.040 ～0.386) and diagnostic odds ratio for 244.64 (95％ CI:17.711 ～3 379.3).The area under the working curve (AUCSROC) of the subjects was 0.981 4 and the Q* index was 0.939 9.Conclusions Meta-analysis on ChromID for diagnosis of clostridium difficile infection revealedChromID had higher sensitivity,specificity,positive likelihood ratio,and negative likelihood ratio,which can be recommended for clinical use.

Objective To study some risk factors of acquired nosocomial pneumonia in tumor case nosocomial infection.Methods 77 tumor case with nosocomial infection were chosen as cases from the patients in hospital for 1:1 case control study.Results It was found that the fatality rate of acquired NP in tumor pattens was 14 3%.Some risk factors of acquired nosocomial infection in tumor case remained significant through logistic regression analysis showed,such as state of an immunosuppression therapy; operation,hospitalization duration,antibiotics application time and mechanical ventilation.Conclusions It was suggested that the iatrogenic pneumonia is comes from multiple risk factors and it should be paid attention. This is the most important step to control nosocomial infection of tumor case in the hospital happen.

Objective To observe the neuroprotection of Baicalin on brain damage following experimental intracerebral hemorrhage in rats.Methods Rat model of intracerebral hemorrhage was induced by collagenase method.The rats were randomly divided into sham operation control group,model group,high-,middle-and low-dose drug group,treated with different dose of Baicalin.The brain water content and the level of SOD,MDA,NO and NOS were measured at the third and seventh day after modeling repectively.Results Compared with the sham operation control group,the brain water content and the level of MDA,NO and NOS were significantly higher,and the level of SOD was significantly lower in model group.The brain water content and the level of MDA,NO and NOS were significantly lower,and the level of SOD was obviously higher in high-,middle-and low-dose Baicalin group than that in model group.Conclusion Baicalin has evident protective effect on brain damage after experimental intracerebral hemorrhage in rats,which maybe related to the increase of SOD and decrease of MDA,NO and NOS.

OBJECTIVE:To prepare borneol-puerarin liposomes,and to investigate its brain-targeting. METHODS:Film dis-persion ultrasonic method was used to prepare borneol-puerarin liposomes. The morphology of liposomes was observed by TEM;the particle size and Zeta potential were measured by laser particle size analyzer;the entrapment efficiency were measured by sepha-dex gel filtration method. Compared with Puerarin injection,brain-targeting of borneol-puerarin liposomes and puerarin liposomes via intravenous injection of mice tail was studied with relative intake rate and peak concentration ratio. RESULTS:Borneol-puerarin liposomes were spherical or quasi-circular;its mean particle size,polydispersity index and Zeta potential were 226 nm,0.263 and-21.3 mV respectively. The entrapment efficiency were(65.32±2.13)%. Compared with Puerarin injection,relative intake rate of puerarin liposome and borneol-puerarin liposome were 1.68 and 2.58,and peak concentration ratio were 1.15 and 1.42. CONCLU-SIONS:Brain-targeted borneol-puerarin liposomes are prepared successfully.
