Objective The aim of this study is to evaluate clinical application of BODE (body mass index, airflow obstruction, dyspnea, and exercise capacity) index in patients with chronic obstructive pulmonary disease (COPD). Methods Forty patients with stable COPD in Xuanwu Hospital of Beijing during September 2003 to December 2007, were recruited in the study, including 25 men and 15 women, aged 38 to 85 years (with a mean of 62 ± 13 years). BODE index was measured for each patient, one year and three years after recruitment, respectively. Severity of COPD, including number and duration of episodes, length of each hospital stay and times of hospitalization due to acute exacerbation of COPD (AECOPD), were recorded. All data were statistically analyzed with SPSS 13.0 software for windows. Results ①There was a remarkable difference in COPD severity between patients with BODE score equal to or greater than five and these with less than five (P <0.01 ). ①BODE score inversely correlated with forced expired volume at the first second ( FEV1 ) in COPD patients (P < 0.01 for those with BODE score equal to or greater than five and P <0.05 for these with BODE score less than five, respectively). ③BODE score positively correlated with number and duration of acute exacerbation, length of hospital stay and times of hospitalization due to AECOPD (P <0. 01 for those with BODE score equal to or greater than five and P < 0. 05 for those with BODE score less than five, respectively). For patients with COPD, their BODE score in the first year positively correlated with that in the third year ( r = 0.834, P < 0.01 ). Conclusions BODE index is a better indicator to evaluate their condition severity in patients with COPD.

Objective To investigate the current situation on the infection of Acinetobacter baumannii in ICU and evaluate the efficiency of resistance control project which was performed in Xiaolan hospital,so as to provide scientific basis for clinical rational use of antibiotics.Methods Used VITEK-2 microbiology analysis system for the pathogen identification and drug sensitivity.Compared drug resistance of Acinetobacter baumannii isolated from the samples of ICU patients in 2012 (before the project executed)with that in 2013 (after the project executed).Results 71 strains and 57strains Acinetobacter bauman-nii were isolated from the ICU in 2012 (before the project executed)and in 2013 (after the project executed)respectively, which majorly isolated from the samples of respiratory system,and occupied 94.4% and 84.2% respectively.The infection rate of multi-resistant Acinetobacter baumannii was decreased from 77.5% to 66.7%,and the resistance rate of Acinetobact-er baumannii to cefepime,ceftazidime,cefatriaxone,tobramycin and cotrimoxazole decreased distinctly after the implementa-tion of drug resistance control management (χ2 > 3.84,P <0.05).Conclusion The drug resistance rates of Acinetobacter baumannii to 14 kinds of routine antibacterial drugs in 2013 were lower than that in 2012 in ICU.Among them,the drug re-sistance rates of Acinetobacter baumannii to 5 kinds of antibacterial drugs decreased distinctly.

Objective To investigate the relationship of sperm morphology with seminal plasma zinc and sperm acrosin activity in male infertile patients.Methods 455 patients with male infertility were divided into 5 groups and 8 groups according to age and sperm morphology respectively.The sperm morphology,seminal plasma zinc and sperm acrosin activity were detected by the Diff-Quik stain,modified 5-Br-PAPS and modified Kennedy methods respectively.Results The percentages of morphologically normal sperm and seminal plasma zinc concentration in the infertile men groups were not different in various age groups(P >0.05 ).The sperm acrosin activity in the age group of 36-50 years was remarkably decreased (P <0.05),while which in other age groups had no statistical difference(P >0.05).Seminal plasma zinc concentration in the infertile men groups were not different in the 8 groups (P >0.05 ).Sperm acrosin activity was decreased with the percentage decrease of morphologically normal sperm (r =0.93,P <0.01).Conclusion The percentage of morphologically normal sperm is not affectd by the age and the seminal plasma zinc,which is positively correlated with the sperm acrosin activity.
