Objective To retrospectively review the clinical characteristics and antimicrobial resistance profile of nosocomial bloodstream infections caused by Klebsiella pneumoniae in surgical patients for better use of antimicrobial agents.Methods The clinical data of the surgical patients who were diagnosed with K.pneumoniae-associated bloodstream infections in Tung Wah Hospital from January 2013 to June 2015 were reviewed and analyzed retrospectively.The diagnosis of bloodstream infections was based on national diagnostic criteria.The pathogens were routinely isolated and identified.Antimicrobial susceptibility testing was carried out by using Kirby-Bauer method.The data were analyzed by WHONET 5.6 software.Results A total of 78 surgical patients were identified with nosocomial bloodstream infections due to K.pneumoniae during this period,including primary bloodstream infections (12.8%,10/78) and secondary bloodstream infections (87.2%,68/78).These infections were mainly associated with surgical and invasive procedures.Nearly 40% of the K.pneumoniae isolates were resistant to ceftriaxone,cefuroxime and piperacillin.ESBLs were produced in 43.6% (34/78) of the K.pneumoniae isolates.The ESBLs-producing strains showed significantly higher resistance rates to various antibiotics than non-ESBLs-producing strains.Piperacillin-tazobactam,amikacin,imipenem,and meropenem still have good antibacterial activity against these K.pneumoniae isolates.However,imipenem-resistant strains are emerging.Conclusions Most of the bloodstream infections caused by K.pneumoniae were secondary to infections in other body sites in surgical patients.Hospital infection control measures should be strengthened.Meanwhile,the clinicians should take full advantages of microbiological laboratory to profile the pathogens and their susceptibility patterns,which is crucial for rational use of antibiotics.

In order to study the association of each item of a health examination and lifestyles with health-related quality of life (HRQoL), a cross-sectional survey by a self-administered questionnaire using the 12-Item Short Form Health Survey (SF-12, version 1) was conducted on 145 government managers that took health examinations in Tongji Hospital, Wuhan, China during 2005. The results showed that the determinations of organic functions including BMI, hemoglobin, blood platelet count, urine protein, urine WBC and lipid metabolism (LDL) were associated with HRQoL. The lifestyle items including age, sex, life satisfaction drinking alcohol and kind of alcohol drunk, drinking tea, sleep quality and adhering to bedtime, working overtime, work stress were associated with HRQoL in the multiple regression models. Sex, age and life satisfaction were the lifestyle items most closely associated with HRQoL, while LDL, hemoglobin and urine protein were the health examination items most closely associated HRQoL. This study revealed that both lifestyle and health examination items were associated with HRQoL.

Objective To investigate the protection effects and possible mechanism of apoptotic effect of compound Xiancao granules on renal ischemia reperfusion injury ( IRI ) in rats. Methods Renal IRI rat model was established by clipping bilateral renal artery.The rats were divided into model control group (n=10), compound Xiancao granules group (n=10) and sham operation group (n=10).All Serum creatinine (Cr) and blood urea nitrogen (BUN) were determined to evaluate kidney function after IRI.Superoxide dismutase (SOD), glutathione peroxidase (GSH-PX) and malondialdehyde (MDA) activity in kidney were measured by colorimetric method. Expression of apoptotic regulatory genes Bcl-2 and Bax in renal tissue were detected by Western blotting.Renal tissue sections were stained by hematoxylin and eosin (HE) and examined under a light microscope. Results SOD and GSH-PX levels of the compound Xiancao granules group (278.1±16.2),(155.96±20.58) U?mg-1 were significantly higher than those of the model control group (196.3±12.1),(109.34±17.81) U?mg-1 (P<0.05). MDA, BUN and Cr (12.49±1.07) nmol?mL-1,(8.9±2.7) mmol?L-1,(149.7±8.5) μmol?L-1 were significantly reduced in the compound Xiancao granules group as compared with those of the model control group (17.32±1.26) nmol?mL-1,(14.6± 3.3) mmol?L-1,(206.1±11.2) μmol?L-1(P<0.05).Bax and Bcl-2 mRNA expression levels of sham operation group were significantly lower, and the Bax and Bcl-2 mRNA expression levels of model control group were significantly enhanced ( Bcl-2:P<0. 05, Bax: P<0. 01 ) . Bax mRNA expression level of compound Xiancao granules group was significantly decreased as compared with that of model control group ( P<0.05) , but Bcl-2 mRNA expression level of compound Xiancao granules group was significantly enhanced as compared with that of model control group (P<0.01). Conclusion These results suggested that compound Xiancao granules has protection effect on renal IRI in rats. The mechanisms may be related to its antioxidant activity and expression of the apoptotic genes such as Bcl-2 and Bax.
