Objective To investigate the occupational hazards of nurses in the supply room,to determine what kind of occupational hazards is most dangerous,and accordingly put forward some suggestions of protective measures.Methods Totally 208 nurses from supply rooms of 4 general hospitals were surveyed with questionnaires.The data of occupational hazards were analyzed.Results Various kinds of occupational hazards happened among nurses in the supply room,and among all occupational hazards,physical damage was the most frequently happened.Conclusions The occupational protection awareness of nurses is relatively weak.They can not properly handle damages caused by occupational hazards,so sufficient attention should be given to it.

The Haemophilus influenzae (Hi) is a common opportunistic pathogen from human respiratory tract. The lower immunity can cause the disease. After the biofilm (BF) is formatted by Hi at the site of infection, the antibiotic sensitivity is declined, which often causes the chronic disease, inducing the difficulty in clinical treatment. In recent years, the pathogenic?ity of Hi BF and BF form related factors have gradually become the focus of clinical and basic research. This paper reviewed recent studies as following.

Objective Carbon/carbon ( C/C) composites are a potential material for bone repair .To improve the hydrophilicity and biological activity of C/C composites , polydopamine coating was prepared on the surface of C /C composites.Methods By changing the coating time and coating environment ( oxygen or air atmosphere ), a series of polydopamine coating samples were prepared . The water contact angle test , scanning electron microscope , energy dispersive spectrometer , atomic force microscope and protein adsorption test were used to characterize the properties of different samples.Then, the data were analyzed to optimize preparation conditions .Results When the concentration of dopamine was 2.0 g/L,and the coating time was 30 min (oxygen atmosphere) +11.5 h (air atmosphere), the water contact angle was decreased from 64.0°(blank sample) to 25.9°, suggesting that the hydrophilicity was improved greatly . The results of the scanning electron microscope , energy dispersive spectrometer and atomic force microscope showed that the coating was uniform and dense .The amount of protein adsorption per sample was 0.2817 mg.Conclusion The polydopamine coating on the C/C composites improves its hydrophilicity and biological activity , which indicates that the polydopamine coated C/C composites will be a new potential material for bone tissue repair .

Objective To investigate the clinical features and prognosis of acute ischemic stroke patients with different infarction patterns.Methods87 patients who underwent diffusion weighted imaging (DWI) within 6 h after symptom onset and visualized acute cerebral infarcts within the middle cerebral artery territory were prospectively studied.According to DWI lesion patterns,the patients were divided into 6 groups.Before MR was performed and 24 h after onset,scores of National Institutes of Health Stroke Scale (NIHSS) were recorded.3 months after onset,scores of modified Ranking scale(mRS) were obtained.ResultsThe baseline NIHSS,infarction volume,occlusion of relevant internal carotid artery or middle cerebral artery and clinical outcome were significantly different among 6 groups(P<0.05).ConclusionDifferent infarction patterns of acute ischemic stroke were associated with clinical symptoms,vascular status,and clinical outcome,that may help to guide treatment and judge prognosis.

Objective To investigate prognosis of acute ischemic patients with internal carotid artery or middle cerebral artery occlusion and define predictors of clinical outcome.MethodsThe clinical and radiological data of 48 stroke patients who underwent magnetic resonance angiography (MRA) within 6 hours of symptom onset and visualized internal carotid artery or middle cerebral artery occlusion on early MRA were analyzed. 90 days after onset, modified Ranking Scale (mRS) scores were obtained and factors related with prognosis were defined by logistic regression analysis.ResultsOf 48 patients, 17 cases (35.4%) got good clinical outcome (mRS 0～2), 31 cases (64.6%) got poor clinical outcome (mRS 3～6) with 7 cases (14.6%) died. In multivariate logistic regression analysis, only large infarction ( OR=21.1, 95%CI 1.4～314.2, P=0.027) and hyperglycaemia ( OR=5.1, 95%CI 1.3～19.8, P=0.019) were independent predictors of poor outcome.ConclusionClinical outcomes of most acute stroke patients with internal carotid artery or middle cerebral artery occlusion are poor. Large infarction and hyperglycaemia are independent predictors of clinical outcome.

Objective To investigate the level and influencing factors of self-efficacy among nurses with needlestick injuries and explore effective strategies to improve self-efficacy.Methods 713 clinical nurses with needlestick injuries had been enrolled by convenience and stratified sampling method to comphte the investigation using the self-designed demographic questionnaire and General Self-Efficacy Scale.Results The average score of the self-efficacy was (2.70 ±0.52) points.69.1％ of the needlestick injury nurses had the sclf-efficacy score at the middle level; only 19.1％ of them had a higher level score on self-efficacy.Gender,title,section,initiative report,work environment,and occupational safety training were identified as the influencing factors of the self-efficiency.Conclusions Even though more than half of the nurses with needlestick injuries had a middle level self-efficacy,they need further improvement.Other influencing factors should be explored in future in order to develop the corresponding management intervention which can strengthen the self-efficacy of nurses with needlestick injuries.

Objective To understand the status quo of knowledge,attitude and practice of clinical nurses’ needlesrick injury (NSI) prevention and its influencing factors.Methods In our cross-sectional study,1020 clinical nurses in different levels of hospitals in Suzhou were recruited to participate the questionnaire survey by stratified cluster sampling.Results The average scores of knowledge,attitude,and practice about NSI prevention were (78.60+15.30),(78.88+8.31) and (70.60+13.86),individually.There was significant correlation among knowledge,attitude and practice.Stepwise regression analysis indicated that knowledge,occupational safety training,section,attitude,rifle,work environment and the level of hospital were the main influencing factors of NSI prevention practice.Condusions NSI prevention knowledge,attitude and practice among clinical nurses are unsatisfactory.Nursing administrators should pay close attention to the nursing staffs’ need of NSI prevention knowledge and provide targeted education to promote the formation of positive attitude,correct bad behaviors and promote healthy behaviors of NSI prevention.

Enterovirus type 71(EV71) causes severe hand-foot-and-mouth disease(HFMD) resulting in hundreds of deaths of children every year; However,currently,there is no effective treatment for EV71.In this study,the EV71 poly-protein(EV71-P1 protein) gene was processed and cloned into the eukaryotic expression vector pPIC9k and then expressed in Pichia pastoris strain GS115.The EV71 P1 pretein with a molecular weight of 100 kD was produced and secreted into the medium.The soluble EV71 P1 protein was purified by column chromatography with a recovery efficiency of 70％.The result of the immunological analysis showed that the EV71 P1 protein had excellent immunogenicity and could stimulate the production of EV71-VP1 IgG antibody in injected rabbits.We suggest that EV71-P1 protein is an ideal candidate for an EV71 vaccine to prevent EV71 infection.
