Objective To explore the effect of different concentrations of hypertonic saline for cerebral ede -ma on blood biochemical and osmotic pressure .Methods 60 cases were randomly divided into the 3% HS group, 7.5%HS group and the mannitol group .The patients were randomly assigned to infusion of 3% HS, 7.5% HS or 20%mannitol (all 2 mL/kg).Blood biochemical and osmotic pressure on patients were measured before and after the treatment among groups .Results Serum Na +, Cl -and osmotic pressure were significantly higher at 2 hours and 22 hours of reperfusion than at baseline (p<0.05) in the 7.5% HS group and the mannitol group .The difference were significant on serum Na +, Cl-and osmotic pressure at 2 hours and 22 hours of reperfusion in the 7.5% HS group and the mannitol group than in the 3% HS group(p<0.05).Conclusion 3% hypertonic saline had less effects on blood biochemical and osmotic pressure than other groups for patients of cerebral edema .It is worthy of popularization and application .

Mesenchymal stem cells (MSCs) play a neuroproteetive effect via a variety of mechanisms.They provide a new idea for the treatment of cerebral ischemia.However,the inadequate sources have significantly limited the possible clinical applications.Carbon nanotubes (CNTs),a new nanomaterials,can not only promote the adhesion,proliferation and differentiation of MSCs in vitro,but also as the cell carriers they can provide good microenvironmental guarantee for the survival of MSCs through the regulation of secretion of cytokines and neurotrophic factors,as well as regulation of biological characteristics of neurons,glial cells,and macrophages after their cell transplantation,provide a good microenvironment guarantee for the survival of MSCs,and promote the effect of MSCs on the therapeutic effect of cerebral ischemia.

Objective To study the serum procalcitonin (PCT)in patients with sepsis clinical application value,for the hospi-tal,infection control,to provide a scientific basis for reasonable Shaanxi General of antibiotics.Methods Retrospective anal-ysis of Shaanxi General hospital of CARF in 2011 May~2013 May 201 cases of patients with ICU,According to the severi-ty of infection were divided into 4 groups(SIRS)63 cases,(Sepsis)40 cases,(Severe sepsis)70 cases,(Septic shock)19 ca-ses,Dynamic analysis of ICU monitoring in 1,3,5,7,10,14,17 days each in the blood in patients with PCT,hs-CRP and WBC levels and blood culture,and PCT on the sensitivity,sepsis diagnostic specificity,positive predictive value,and negative predictive value,diagnostic accordance rate.Results PCT levels of SIRS and Sepsis (1.92 ng/ml)(10.8 ng/ml)group,the Severe Sepsis (24.0 ng/ml),and Septic shock compared (34.0 ng/ml)group,the difference was statistically significant (q1=13.8,q2=15.6,q3=17.9,P<0.05).Four groups of hs-CRP and WBC count,and there was no statistically significant difference (F=5.10,P>0.05),PCT levels and the severity of sepsis in positive correlation (r=0.781).The positive rate of blood culture in 26.6%,and PCT the on diagnosis of sepsis sensitivity,specificity,positive predictive value (PP),negative predictive value (NPV)were 87.2%,85.4%,78.9% and 89.3%,respectively,for sepsis diagnosis coincidence rate 85%, the increase of PCT level(≥ 1 ng/ml)was anindependent index 28 natural deposit rate.Conclusion Compared with PCT hs-CRP and WBC could better evaluate the severity of sepsis,and dynamic j udgment of sepsis disease prognosis was more sensitive.Joint detection with blood culture could improve the of accuracy differential diagnosis of sepsis,and to guide clinical rational application of antibiotics.The change of concentration of PCT daily can help predict mortality risk in patients with sepsis in ICU of the hospital,reduce complications and reduce mortality.

Objective To analyze the β-lactamases-producing Escherichia coli which were isolated from hospital specimens from Jun 2012 to Dec 2014,and provide a more accurate evidence to guide drug-selecting for antibacterial use.Methods An-alyzed 1 587 E.coli from patient sample selected between Jun 2012~Dec 2014 using the microbial analysis system manufac-tured by ZHUHAI DL BIOTECH CO.LTD,A phenotypic test was also conducted to test ESBLs.Results 1 587 stains of E-.coli were isolated,which counted for 23.9% of the specimens;901 stains (56.8%)out of total 1 587 stains appeared to be ESBLs-producing E.coli,and others were non-ESBLs-producing E.coli.The 1 587 Escherichia coli mainly came from De-partment of Urology (408,weight 25.7%),Department of Endocrinology (271,weight 17.1%),Department of Respiration (249,weight 15.7%).Rine specimen contributed 609 stains (47.3%),411 E.coli stains (31.9%)were discovered in spu-tum samples,and 83 stains (6.5%)showed in blood samples.The resistance to imipenem were discovered in the analysis. The rates of resistance to penicillins,cephalosporins were over 90.0%,the rates of resistance to Levofloxacin,ciprofloxacin were above 70.0%,and resistance rates to amoxicillin-clavulanic acid,Ticarcillin-clavulanic acid,piperacillin/tazobactam, amikacin were lower than 7.7%.Conclusion The drug-resistance of the E.coli were increasing over the past three years. There was a significant portion of MDR and PDR present in the trend.Thus,the reinforcement of the drug-resistance survey and testing have a far-reaching meaning to promote rational drug selecting.

Objective To investigate the changes of drug resistance related genes and drug resistance of Acinetobacter Bau-mannii in hospital,and provide evidence for rational use of antibiotics in clinic.Methods A retrospective analysis of Shaanxi Corps Hospital of Chinese Peoples’s Armed Police Forces from 2011 to 2015 from clinical samples of 11 521 specimens were isolated and cultured 1 861 strains of Acinetobacter Baumannii,drug susceptibility test by K-B method.The antimicrobial minimum inhibitory concentration (MIC)according to the 2014 edition of the CLSI judgment criteria of judgment.Results 1 861 strains of Acinetobacter Baumannii were detected drug resistance genes gyrA,parC,OXA-51,OXA-23,int on the 1,I TEM,AAC (6’)-1,AAC (3’)-1,ant (3)-1,ant (2)-1 and Caro gene detection rates were 50.4%,72.1%,70.9%,55.7%, 56.2%,65.6%,12.9% and 89.9% respectively,and SHV,IMP and VIM genes were not detected.The sequencing results showed that gyrA and parC gene mutation was the main cause of quinolone resistance.The antibiotic resistance of Acineto-bacterBaumannii was an increasing trend year by year,and 1 861 strains has 1 419 strains showed multiple drug resistance, all strains were sensitive to polymyxin.In 2015,quinolones aminoglycosides resistance rate was more than 65%.To imipen-em,meropenem and Cefoperazone/sulbactam were 35.17%,36.01% and 42.40%.Conclusion The detection rate of Acine-tobacter Baumannii is increasing year by year,and the drug resistance and multi drug resistance is increasing year by year.It is necessary to strengthen the clinical rational drug use andcontrol the hospital infection.

OBJECTIVE: To analyze the prevalence of bacterial infection and drug sensitivity after liver transplantation so as to provide reference to effective clinical therapy. METHODS: A retrospective survey of 113 patients who underwent orthotopic liver transplantation was carried out. RESULTS: The reported total incidence of bacterial infection after liver transplantation was 45.1%, while the verified incidence was 28.3%. The major bacterials were Klebsiella pneumoniae and Enterococcus faecom. Multidrug-resistant was observed. CONCLUSION: It is very important to prevent bacterial infection and use antibiotic rationaly. Selection of effective antibiotics according to etiologic data and resistance of bacterial can help prevent the occurance of drug resistant strains.
