OBJECTIVE:To systematically analyze the efficacy and safety of benazepril vs. captopril in the treatment of prima-ry hypertension and provide evidence-based reference for the clinical treatment. METHODS:Cochrane Library,PubMed,EM-Base,CJFD,VIP database and Wanfang database were retrieved to collect the randomized controlled trials (RCT) of benazepril (experiment group)vs. captopril(control group)in the treatment of primary hypertension. After information collection and quality evaluation,Meta-analysis was conducted by using Rev Man 5.0 software. RESULTS:Totally 7 RCTs involving 405 patients were in-cluded. The results of Meta-analysis showed that the level of systolic blood pressure(SBP)[MD=-2.06,95%CI(-3.75,-0.38), P=0.02] and diastolic blood pressure(DBP)[MD=-3.10,95%CI(-5.19,-1.01),P=0.004] in experiment group was sig-nificantly lower than control group;however,there were no significant differences between the efficacy rate of antihypertension [OR=1.63,95%CI(0.69,3.83),P=0.26] and incidence of adverse drug reactions(ADR)[OR=0.81,95%CI(0.46,1.41),P=0.45] in 2 groups. CONCLUSIONS:Benazepril can more effectively lower the blood pressure of patients with primary hypertension than captopril. Due to the limitation of methodology quality,it remains to be further verified by high-quality and large-sample RCT.

Objective To explore the relationship between social support and professional identification among nursing students,and to examine the mediating role of resilience.Methods A total of 650 nursing students were evaluated with Social Support Rating Scale,Professional Identity Questionnaires for Nursing Students and Chinese revision of Connor-Davidson Resilience Scale.Results The scores of nursing students' social support,resilience and professional identification were (38.93±5.30),(66.79±11.93),(57.45±9.95).Professional identification could positively influence their professional identification(r=0.233-0.422,P＜0.01).Resilience mediated the relationship between social support and professional identification,the effect sizes were 52.27％.Conclusions Resilience plays a mediating role between social support and professional identity.It is important to pay attention to social support and resilience and take proper interventions to promote nursing students professional identification.
