Chinese Journal of Primary Medicine and Pharmacy 2014;21(8):1123-1126
Objective To understand the hospital intensive care unit(ICU) pathogenic bacteria distribution and drug resistance for providing the basis for rational drug use and hospital infection control and prevention.Methods The drug resistance of 749 strains of pathogenic bacteria the separated from ICU was analyzed from January 2009 to December 2012.VITEK 2 Compact automatic bacteria identification instrument was used to detect bacteria identification and drug sensitive test using.Results There were Acinetobacter baumannii(208 strains,27.8%),Pseudomonas aeruginosa(108 strains,14.4%),E.coli (96 strains,12.8 %),Staphylococcus aureus (76 strains,10.1%),Klebsiella pneumoniae(62 strains,8.3%) mainly accupied in 749 strains of pathogenic bacteria.The species was mainly from sputum specimens sources (503 strains,67.2%) ; the separation rate of Methicillin-resistant staphylococcus aureus (MRSA) was 82.9% (63/76) ; the separation rate of Imine resistance from South pseudomonas aeruginosa(IRPA) was 22.2% (24/108) ; the separation rate of resistance to carbon penicillium alkene antimicrobial acinetobacter baumannii (CR-AB) was 88.0% (183/208).The resistant rate of Acinetobacter baumannii to amikacin was from 28.6% to 31.5%,the other 20 kinds of antimicrobial drug resistant rate was as high as 81.6%-100.0% ; Pseudomonas aeruginosa to ciprofloxacin,ofloxacin,aztreonam and piperacillin/tazobactam resistant rate of 11.6%-25.0%.Conclusion Detection of pathogens in ICU,multi-drug resistance is serious,the hospital should strengthen the bacterial drug resistance monitoring,rational use of antimicrobial drugs,reduce the nosocomial infection.

Clinical Medicine of China 2014;30(5):472-474
Objective To investigate the distribution of the Bauman acinetobacter baumannii (IRAB) resisted to imipenem and character of drug resistance.Methods Retrospective analyzed 517 strains of IRAB and 319 strains of imipenem drug resistance of acinetobacter baumannii from South Africa (not IRAB) by VITEK 2 compact automatic bacterial culture identification.Results IRAB positive rate was 61.8% (517/836).The main source of IRAB was from sputum(85.5% (442/517)).The constitute ratio of main areas in IRAB was ICU ward (55.9%) and only 7.8% in non-IRAB.The resistant rate of IRAB to amikacin was 27.2%.The resistant rate of non-IRAB to Amikacin and piperacillin/tazobactam were 8.0% (21/262),8.2% (26/317),suggesting the good antibacterial activity.In terms of rate of resistance drug,apart from Cefazolin,Cefotetan,Cotrimoxazole,Nitrofurantoin,the sort of antibacterial drugs against IRAB was obviously higher than that of non-IRAB,and difference was statistically significant (P < 0.05).Conclusion Drug resistance surveillance should be strengthened because of high detection rate and drug resistance in ICU in terms of IRAB.Combination therapy and related intervention measures might effective control of infection and IRAB.

9.Diagnosis of vascular cognitive impairment
International Journal of Cerebrovascular Diseases 2009;17(2):124-127
Vascular eognitive impairment (VCI) is a large class of syndromes from mild cognitive impairment to dementia, which are caused by the cerebrovascular risk factors (eg, hypertension, diabetes and hyperlipemia), obvious (eg, cerebral infarction and intracerebral hemorrhage) or unobvious cerebrovascular diseases (leukoaraiosis and chronic cerebral ischemia). Accurate early diagnosis provides the best treatment opportunity and slows down the progress of the disease. In recent years, the research on VCI has made a great progress. This article reviews VCI from the aspects of the etiology, clinical manifestation, neuropsychology, imaging, neuroelectrophysiology, biomarkers, and diagnostic criteria.
