Conclusion:Medical staff blood-borne occupational exposure risk is high , the hospital infection control personnel must pay attention to occupational exposure of the whole education , strengthen the administration of the occupation-al exposure of ethics , reduce the risk of occupational exposure and injury .

Objective To examine the effect of labouring in water on analgesia of vaginal delivery.Methods From June 2009 to February 2011,38 women who had volunteered to deliver in water in the obstetrical department were set as the observation group,another 70 women who chose vaginal delivery were named as the control group in the corresponding period.The items of labor pain,satisfaction with the birth experience,length of labor and neonatal outcomes were compared.Results The pain level of the observation group after labouring in water decreased compared with that before immersion in water.The delivery course was not influenced with a high rate of vaginal delivery.Conclusions Labouring in water can alleviate delivery pain,increase rate of vaginal delivery with no influence on delivery course and outcome of mothers and infants.It is a safe and effective analgesia method which should be widely applied.

Objective To observe the efficacy of naloxone combined with Buyanghuanwu decoction on cong -nitive function of multi -infarct dementia(MID) patients.Methods 46 patients with MID were treated with Nalox-one Hydrochloride and Buyanghuanwu decoction .Mini -mental state examination ( MMSE ) , activity of daily living ( ADL) scale and hachinski ischemic scale score ( HIS) were used to estimate the therapeutic effect after the treatment for 30 days.Results Compared to 30 days before,the MMSE score and ADL score improved after the treatment (t=3.247,3.469,all P<0.05),and the score of HIS declined (t=3.384,P<0.05).Conclusion Application of nal-oxone combined with Buyanghuanwu decoction can significantly improve congnitive level and ADL function in multi -infarct dementia patients .

OBJECTIVETo investigate the effect of IL-12 on IFN-gamma and IL-10 production of peripheral blood mononuclear cells (PBMC) in chronic hepatitis B virus infection patients during IFN-alpha treatment.

METHODSBefore and after IFN-alpha treatment of 3 months and 6 months, PBMC of 20 patients with chronic hepatitis B virus infection were collected and cultured in vitro in the culture fluid containing PHA (100 microg/ml), HBcAg (1 microg/ml), or HBeAg (1 microg/ml) for 48 h under the condition of the presence or absence of IL-12 (10 ng/ml). Then the levels of IFN-gamma and IL-10 were determined by ELISA.

RESULTSThere were 12 responders and 8 nonresponders to IFN-alpha treatment. In the responders, the enhancing effect of IL-12 on IFN-gamma production was significantly greater after IFN-alpha treatment than before the treatment. The production of IL-10 was suppressed in the presence of IL-12 after 3 months and 6 months of IFN-alpha treatment. In the same treatment time, the level of IFN-gamma in the presence of IL-12 was significantly higher than that in the absence of IL-12. To the nonresponders, the enhancing effect of IL-12 on IFN-gamma production was also significantly increased after IFN-alpha treatment. Moreover, in the same treatment time, the level of IFN-gamma in the presence of IL-12 was significantly higher than that in the absence of IL-12.

CONCLUSIONSThe enhancing effect of IL-12 on IFN-gamma production of PBMC in patients with chronic hepatitis B virus infection is increased during IFN-alpha treatment. IFN-alpha and IL-12 may enhance the efficacy for the treatment of chronic hepatitis B virus infection.

Objective To investigate the clinical value of the simple clinical score (SCS) in Emergency Department.Methods A total of 655 patients with critically illness admitted from July 1,2011through August 31,2011 were enrolled to evaluate the clinical application of SCS in emergency rescue room by analysis of the relationship between SCS and outcome of patients,and the correlation between each factor of SCS and the risk of death. Results The higher SCS,the higher hazard ratio for death.Differences in the hazard ratio for death among groups with different scores of SCS were statistical significance ( P ＜ 0.01 ).According to Chi-square test,there were significant differences in each factor ( except body temperature &unable standing or need Home Health Aide) among the groups of SCS ( P ＜ 0.05 ). Binary logistic regression analysis of each factor showed that age,diabetes,coma,pulse,systolic pressure and respiratory rate had significant correlation with patient mortality. After logistic regression analysis,age,diabetes,coma,pulse,systolic pressure and respiratory rate are significantly related to the mortality of patients.Conclusions The SCS scoring system is useful to make a precise evaluation of critically ill patients in the emergency department.When emergency rescue is carried out,particular stress should be focused on age,diabetes,coma,pulse,systolic pressure and respiratory rate.
