Objective to investigate the situation of occupational health of nurses,so as to provide a reference for protecting the health of nurses. Methods Cluster sampling method was employed in this study. totally 1 204 nurses of two three-level general hospital and a cancer hospital in Bei-jing were randomly surveyed with homemade health of nurses′cross-sectional questionnaire,and a nurse medical examination report was access at the same time. Results there was statistically significant difference in the incidence of nurses work pressure and work fatigue in different hospitals and different departments(P < 0.05). 95.18% of the nurses undergo regular medical examinations,of which 56.97% were found abnormal. the dif-ferences in the incidence rate of abnormal medical examination results in nurses were statistically significant among different hospital and different de-partments(P < 0.05). Conclusion Great job stress and work fatigue are observed in nurses,and they have health problems. It is necessary for the hospital to take appropriate interventions to improve physical and mental health nurses.

Durg-eluting stent has been regarded as the milestone in the history of PCI for their efficiency in the prevention of coronary arterial restenosis after percutaneous coronary intervention. But unfortunately intra-stent thrombosis continues to be a serious complication of contemporary DES use. The incidence of drug-eluting stents thrombosis is at least not lower than that of bare metal stents at present. The clinical consequences of stent thrombosis are frequently catastrophic, including death in 40% to 50% of the cases or major myocardial infarction in 60% to 70%. Premature discontinuation of standard antiplatelet therapy is by far the most important predictor of stent thrombosis with DES and other predictors included renal failure, diabetes, bifurcation lesions, multiple lesions or multivessel disease, long stents, female, advanced age, stent underexpansion and residual stenosis etc. The delayed endothelialization may be the underling mechanism of DES thrombosis.

Objective To detect the mutant prevention concentration (MPC) of macrolide resistant Streptococcus pneumoniae, to amplify the resistance gene of Streptococcus pneumoniae mutants selected in the mutant selection window (MSW), and to investigate the mechanism in the resistance of Streptococcus pneumoniae to macrolides. Methods The Streptococcus pneumoniae strain ATCC49619 was enriched in broth, and the bacterial concentrations were adjusted to 1010 colony forming units per milliliter. The minimal inhibitory concentration (MIC), MIC for 99 % of input cells (MIC99), provisional MPC (MPCpr), and MPC of roxithromycin and azithromycin for Streptococcus pneumoniae were determined by agar plate dilution method. The ermB and mefA of Streptococcus pneumoniae mutants selected in the MSW were obtained by PCR method and sequencing. Results The MPCs of roxithromycin and azithromycin for ATCC49619 were 0.80 ?g/ml and 0.51 ?g/ml, and the MPC/MIC99 were 5.0 and 3.9. The ermB gene was detected in Streptococcus pneumoniae mutants selected in the MSW. Conclusion Adjustment of the drug dose may limit the enrichment of macrolide-resistant Streptococcus pneumoniae mutant. The mechanism in the resistance of Streptococcus pneumonia to macrolides may be associated with ermB genes carried.

Objective: To observe the therapeutic effect of intravenous thrombolysis of recombinant streptokinase (r SK) on acute myocardial infarction (AMI) and its safety. Methods: Twenty patients with AMI received r SK for thrombolysis.The reopening rate of infarct related artery,side effect and the fatality rate in hospital were observed. Results: The reopening rate of infarct related artery was 75%. The incidence of slight hemorrhage, fever, low blood pressure,which could be corrected in short time, was 5%, 15%, 15%, respectively. The fatality rate 5 weeks after AMI was 10%. Conclusion: The therapeutic effect of r SK in the thrombolytic therapy of AMI is definite and the safety is fine.
