Objective To systematically review the effect of cluster-based nursing for prevention of deep venous catheter-related bloodstream infection.Methods We searched the domestic literature,using RevMan5.2 software for statistical processing.Results A total of 13 qualified literature was included.Its combined OR=0.33,95％CI=(0.26,0.43),indicating that the cluster-based nursing could significantly reduce deep venous catheter-related bloodstream infection rate.Conclusions Cluster-based nursing is a practical nursing intervention,which should be promoted in clinical practice.

Objective To evaluate the effect of Angio-Seal vascular closure device by the femoral artery hemostasis.Methods Relative literature was searched by computer,according to the inclusion and the exclusion criteria,which were analyzed by RevMan5.2 software.Results A total of four studies of randomized controlled trial were brought into this research,the total sample size was involved in 3 191 cases,the sample size of the intervention group and the control group respectively was 1 583 and 1 608.The analysis results showed,Angio-seal vascular closure device can significantly shorten the time of hemostasis after femoral artery interventional therapy in patients and the limb braking time.The sensitive analysis results showed that the results stability were high and the conclusions were reliable.Conclusions Application of Angio-seal vascular closure device can significantly shorten the interventional therapy in patients with bleeding time and braking time.

Objective To assess systematically the effect of (cognitive behavior therapy,CBT) on PANSS of schizophrenia.Methods Relative literature was searched by computer at home according to the inclusion and the exclusion criteria,which were analyzed by RevMan5.2 software,and literature selection and repetition were used according to the Note Express software.Results A total of 11 studies were brought into the study.According to the different time of intervention,the results showed that,the cognitive behavior therapy intervention continued for 2 months,I2 was 80％,the statistical result of random effects model analysis was [SMD=-0.64,95％CI (-1.14～-1.13),P＜0.05]; the cognitive behavior therapy intervention continued for 6 months,I2 was 64％,the statistical result of random effects model analysis was [SMD=-0.40,95％CI (-0.71,-0.08),P＜0.05]; the cognitive behavior therapy intervention continued for 12 months,the statistical result of fixed effects model analysis was[MD=-5.65,95％CI(-6.20,-5.09),P＜0.01].The replacement of statistical models for the sensitive analysis showed that the result was stabile and reliable.Conclusions The cognitive behavior therapy may reduce PANSS of patients with schizophrenia,But because the influence of some factors,the time of intervention is limited,so the result of this research is that the best intervention time for clinical symptoms improvement is from 6 months to 1 year.

Objective We aimed to assess systematically the effect of pressure treatment instrument on pre-venting deep venous thrombosis of lower extremity for hospitalized patients.Methods Relative literature was searched by computer at home according to the inclusion and the exclusion criteria,which were ana-lyzed by RevMan5.2 software and literature selection and repetition were used according to the Note Ex-press software.Results A total of 13 studies of randomized controlled or not randomized controlled trials were brought into the study by fixed effects model.A total of 1 194 were included into the study,599 in the experimental group and 595 in the control group.Literature analysis showed that pressure treatment in-strument can decrease the incidence rate of deep venous thrombosis of lower extremity (OR=0.24,OR95％ CI:0.15～0.37,P＜0.01) and increase venous blood flow velocity (OR=0.52,OR95％CI:0.25～0.80,P＜0.01).By replacing the statistical effect model,the sensitivity analysis showed a stable and reliable result conclusion.Conclusions Pressure treatment device can reduce the incidence rate of lower extremity deep venous thrombosis in hospitalized patients,prolong the survival time and improve the quality of life,and can also reduce the complications caused by anti-thromboembolic drugs.It is favored by clinical workers more and more,and it is worthy of further promotion and application.
