Objective To research the association between the prognosis of Acinetobacter baumannii infection and drug resistance among patients in the intensive care unit( ICU). Methods Eighty-four patients with Acine tobacter baumannii infection from February 2003 to April 2009 in Peking University Shenzhen Hospital ICU were retrospectively analyzed and divided into alive group(59 patients) and dead group(25 patients) by using 30-day mortality. The impact of drug resistant Acinetobacter baumannii on mortality was assessed by binary logistic regression. Results The mortality of patients with Acinetobacter baumannii infection was related to age, haematological malignancy, the Chanson Comorbidity Index, APACHEII score, multidrug-resistant Acinetobacter baumannii ( MDRAB) , carbapenem-resistant Acinetobacter baumannii (CRAB ) , septic shock and antimicrobial inappropriate therapy by univariate analysis( P < 0.05). Binary logistic regression revealed that CRAB( OR = 3. 360,95%CI: 1. 563 ～7.223,P< 0.05)and the Charison Comorbidity Index( OR = 1. 633,95% CI: 1. 201 ～2. 221 ,P <0.05) were independent risk factors. Conclusions The prognosis of Acinetobacter baumannii infection was closely correlated with drug resistance. The patients with CRAB infection had a higher mortality.

Objective To assess antibiotic prescription habits,cost pattern and the prospective intervention in Intensive Care Unit was analyzed.Methods Data on antibiotic utilization and antibiotics susceptibility were col-lected prospectively from individual electronic charts from July 2014 to September 2014.Results 225 of 246 patients surveyed used antimicrobial during the ICU stay,and antibacterial drug utilization rate was 91.46%.Cefperazone-sulbactam and piperacillin-tazobactam were the most prescribed medications.Total defined daily dose ( DDDs) was 1121.1 DDDs.Bacteria culture was 98 positive in 677 cases and 101 pathogenic bacteria were isolated.Conclusion Interventional programs should focus on promoting infectious control with rational antibiotic prescription aimed at mini-mizing the future emergence of bacterial resistance and futile.

Objective To explore the role of PI3K/AKT signaling pathway in total hepatic ischemia-reperfusion(I/R)-induced lung injury in rats.Methods This study was divided into 2 sub-projects.(1)36 rats were killed respectively at preischemia and after reperfusion,the lung tissue was then sampled.(2)12 rats were randomly divided into Wortmannin group and model control group. AKT,p-AKT protein expression,apoptotic cells and PCNA protein expression were tested respectively by Western blot,TUNEL and immunohistochemistry analysis.Results(1)Compared with that in preiscemia group,after I/R the apoptotic index (AI)was increased,the p-AKT/AKT ratio and PCNA-positive index showed bidirectional changes,and the histological changes were well identified.(2)p-AKT/AKT ratio showed a positive correlation with PCNA-positive index and a negative correlation with AI.(3)Compared with control group,the p-AKT/AKT ratio and PCNA-positive index were lower,histological changes was more significant and AI was higher in Wortmannin group. Conclusion PI3K/AKT signaling pathway had protective effect on lung injury induced by hepatic I/R,which was potentially mediated by anti-apoptosis and promoting proliferation.

Objective To evaluate the influence of glutamine(Gln)-enriched total parenteral nutrition on nutritional status,suppression of excessive systematic inflammatory responses and immunological competence on critical patients in ICU.Methods Sixty critical patients were included in a randomized controlled clinical trial and divided into Gln group and control group,with 30 case for each group.Both groups received isocaloric and isonitrogenous nutritional formulas on everyday.In addition,Gln was added to Gln group from day 1 to day 8.On day 1 and 8 after treatment,serum albumin,proalbumin,transferin,IgA,IgG and IgM were determined respectively.The plasma level of CPR,IL-6,TNF-?,blood suger,liver function were also monitored.Results (1)The level of serum albumin,proalbumin,transferin,IgA,IgG,and IgM decreased in all patients.Albumin,proalbumin,transferin,IgA,IgG,and IgM were significantly improved in Gln group on day 8 compared with control group and before treatment(P

Objective To establish a simple,rapid,accurate and practical method for determination of chloride in drinking water by chloride ion-selective electrode.Methods The chlorine ion-selective electrode was used as indicator electrode and type217saturated calomel electrode of the double salt bridge(the lower salt bridge was filled with a solution of0.1mol/L potassium nitrate)was used as reference electrode.The contents of chloride in water were calculated using the calibration curve method in the electrolyte containing0.1mol/L potassium nitrate.Results The linear range of the method was10 -5 -10 0 mol/L and the best lin ear range was10 -4 -10 -1 mol/L with r=0.9999and the slope=53.5?0.667.The detection limit,recovery rate and coefficient of variation(CV)were0.3545mg /L,94.2%-102.2%(mean98.1%)and2.8%respectively.The suitable pH for the determination of the method was2-10.In the solution containing3.545mg/L chloride,50times more BrO -3 ,NO -2 ,CH 3 COO - ,SO 42- ,F - ,CrO 42- and10times more CO 32- could not interfere with the detection,but Br - and I - were interfering factors.The re-sults obtained by the chlorine ion-selective electrode method and the national standard determination method showed no statistic differences.Conclusion The method was easy to operate,rapid,accurate and suitable for determination of chloride in water.

The action of BTHP on a-adrenoceptor was studied in anococcy-geus muscles, vas deferens and cell membrane of cerebral cortex of rats and aortic strips, saphenous vein of rabbit. BTHP produced parallel shifts to the right of dose-response curves for phenylephrine in rat anococcygeus muscle and rabbit aortic strips without change in the maximal responses. Their pA2 values were 5.8 and 5.86 respectively. BTHP was also a competitive antagonist for presynaptic and postsynaptic ?2-adrenoceptors on prostatic portion of rat vas deferens( pA2 against clonidine=5.2 ) and on rabbit saphenous vein ( pA2 against B-HT920=5.3 ) . BTHP decreased in dose-dependent manner 〔8H〕 prazosin and 〔3H〕 clonidine specific binding to ?1- and ?2- adrenoceptors on cell membrane of cerebral cortex in rats with IC50 of4 and 9.5 ?mol/L and with Ki ( apparent dissociation constant ) of 3.5 and 8.1?mol/L respectively, suggeating that BTHP has affinity for both ?1 and ?2- adrenoceptors of rat cerebrance.

Myocardial protection has been the subject of intensive investigation. Several studies have suggested that Ginsenosides may protect against ischemia/reperfusion injury. The isolated, working rat heart model was used in this study to evaluate the effects of St. Thomas' Hospital Cardioplegic Solution containing various concentrations of Ginsenosides on the enhancement of myocardial protection following hypothermic ischemic arrest (20 ℃, 120 min). The added concentration of Ginsenosides in cardioplegic solution was 0(control), 50, 100 150?g/ml, respectively. Recoveries of aortic flow, cardiac output, and minute work were markedly improved by adding Ginsenosides to cardioplegia. Dose-response study indicated that 100?g/ml in cardioplegia had the best protective effects, in which group the generation of thiobarbituric acid reactive materials (MDA) was markedly reduced. Our results indicated that Ginsenosides provides additional myocardial protection in St. Thomas' Hospital Cardioplegia. Addition of Ginsenosides to cardioplegia may protect the ischsmic myocardium from free-radical injury also.
