To compare the effectiveness and safety of spinal versus general anesthesia for arthroplasty with respect to deep vein thrombosis(DVT),pulmonary embolism (PE) and epidural hematoma.Randomized controlled trials involving spinal and general anesthesia for arthroplasty were searched.Quality assessment were analyzed according to the Cochrane Collaboration's rule.A total of 12 trials involving 1023 participants met the inclusion criteria,Meta-analyses showed that spinal anesthesia may reduce the incidence of DVT or PE after arthroplagty without anticoagulant.There is no difference in the incidence of DVT and PE when anticoagulant is used.Whether anticoagulant was used or not,no epidural hematoma was observed after using the two anesthesia methods.

Objective To study the therapeutic effect of Danshen injection combined with conventional therapy on children with recurrent asthmatic bronchitis. Methods A prospective study was conducted. Fifty-five children with asthmatic bronchitis admitted in People's Hospital of Henan Province from January 2012 to July 2014 were enrolled and randomly divided into a integrative Chinese and western medicine group(30 cases)and a conventional therapy group(25 cases);in the same period,18 healthy children having passed physical examinations were chosen as the healthy control group. In the conventional therapy group,rest,oxygen inspiration,anti-infection, fluid supplement and aerosol inhalation,etc. were given,while in the integrative Chinese and western medicine group,based on the similar conventional therapies,additionally Danshen injection 0.4 mL · kg-1 · d-1 was given,once per day for a total of 14 days. The wheezing remission time and the pulmonary rale extinction time were observed in the two patient groups,and the fractional exhaled nitric oxide(FeNO)content was investigated in the three groups. Results The wheezing remission time and the pulmonary rale extinction time of the integrative Chinese and western medicine group were obviously shortened compared with those in the conventional therapy group〔the wheezing remission time(days):2.3±0.8 vs. 5.2±1.1,the pulmonary rale extinction time(days):6.8±1.5 vs. 8.4±1.1,both P<0.01〕. The contents of FeNO in the integrative Chinese and western medicine group and the conventional therapy group before treatment were significantly higher than those in the healthy control group(×10-9:30.3±9.5,30.4±8.2 vs. 13.6±3.4,both P<0.01),but after treatment the FeNO levels of both patient groups were markedly lowered,and the degree of change in integrative Chinese and western medicine group was more significant(×10-9:18.6±4.7 vs. 24.0±6.8,P<0.01). Conclusion Danshen injection combined with conventional therapy can obviously down-regulate the FeNO content,alleviate the airway inflammation,effectively relieve the children recurrence of asthmatic bronchitis.

OBJECTIVE To probe how to avoid the complication after intravenous infusion for the elders. METHODS The cause of the complication in infusion therapy for the elders with a total of 80 cases in the past three years was analyzed retrospectively. RESULTS Among the complications after intravenous infusion for 80 elders,leakage injury accounted for 47 cases(58.5%), and phlebitis accounted for 21 cases(26.8%),respectively. CONCLUSIONS As the elders′ blood vessel wall is very thin,the intravenous infusion often causes injury,the nurses should pay more attention to operating of intravenous infusion for the elders,observing regularly,and prolonging the time for pressing the pinprick after pulling out the dropper,in order to reduce the coming of injury.

OBJECTIVE To evaluate the methods of improving the air quality in the outpatient departmant area.METHODS The amount of outpatients in different time periods in the morning were calculated in the specialist consulting area;the bacteria in the air collected from the clinic room were collected and cultured in general nutrition agar medium and compared the efficacy for the improvement of air quality between the new and the old methods.RESULTS The air quality of the specialist consulting area was improved significantly through the ventilation and cleaning-floors depending on the amount of outpatients(P

OBJECTIVE To verify the effect of batch monitoring system insteod of the indicator in the package.METHODS From Apr 17,2007 to Jul 29,2008,the batch monitoring system was used to monitor the sterilization effect of each batch,at the same time,inside each package we placed the indicator as control.RESULTS A total of 7057 batches were monitored,in which 7051 were eligible,and among 166870 packages in all,the indicators were all eligible,which included 56600 dressing packages and 110270 instrument packages.There was no difference between batch monitoring system and indicators.CONCLUSIONS The effect of batch monitoring system is credible,and the indicator inside package can be replaced.

Objective To compare the abnormal influence of Ureaplasma urealyticum(UU) and human papillomavirus(HPV) infection on early pregnant women,and to investigate the correlation between reproductive tract infection with spontaneous abortion in early pregnant women.Methods A total of 460 pregnant women were included in the observation subjects,including 230 cases of spontaneous abortion (observation group) and other 230 normal pregnant women of delivery as the control group.The cervical swab samples were collected from the research subjects of the two groups and performed the UU and different types of HPV detections by using corresponding PCR reaction reagents.Results The UU total infection rate among 460 pregnant women was 17.83%(82/460),which of the observation group was 24.8%(57/230) and which the control group was only 10.9%(25/230),the difference between the two groups was statistically significant(P<0.01).The HPV total infection rate was 20.2%(93/460),which of the observation group was 29.1%(67/230) and which of the control group was only 11.3%(26/230),the difference was statistically significant.Among them,the single subtype HPV infection proportion was 14.1%(65/460),the multiple subtype HPV mixed infection proportion was 6.1%(28/460),while the high risk type HPV infection rate was 18.3%(84/460) and the low risk type HPV infection rate was 8.91%(41/460).The infection rate of UU combined HPV was 2.6%(12/460),in which the observation had 11 case and control group had 1 case,the difference was statistically significant (P<0.01).Conclusion Infection of UU and HPV in early pregnant women may lead to spontaneous abortion.But its concrete mechanism and the role of different types of HPV need to be further studied.
