ABSTRACT
OBJECTIVE:To evaluate the efficacy and safety of cerebrolysin in adjuvant treatmenut of acute cerebral infarction systematically,and to provide evidence-based reference in clinic.METHODS:Retrieved from SCI,Cochrane Library,EMBase,PubMed,CJFD,VIP and Wanfang Database,RCTs about cerebrolysin combined with routine plan (trial group) vs.routine plan alone or combined with placebo (control group) in adjuvant treatment of acute cerebral infarction were collected.After data extraction and quality evaluation by using Cochrane systematic review manual 5.1.0,Meta-analysis was conducted by using Rev Man 5.2 statistical software.RESULTS:A total of 20 RCTs were included,involving 3 313 patients.Meta-analysis showed that NIHSS score [MD=-1.77,95％CI(-2.33,-1.21),P＜0.001],response rate [OR=2.85,95％CI(1.75,4.63),P＜0.001] and Barthel index (BI) score [MD =7.30,95 ％ CI (3.48,11.13),P＜ 0.001] in trial group were significantly higher than control group,with statistical significance.There was no statistical significance in disability rate [OR=0.46,95％ CI(0.20,1.03),P=0.06],mortality [OR=0.79,95％ CI (0.52,1.19),P=0.25],the incidence of ADR [OR=1.04,95％ CI (0.85,1.27),P=0.72] or the incidence of severe ADR [OR=0.01,95％CI(-0.02,0.04),P=0.51] between 2 groups.CONCLUSIONS:Cerebrolysin is good for adjanctive therapy of acute cerebral infarction,can significantly improve neurologic impairment and life quality and dosen't increase the incidence of ADR.
ABSTRACT
Objective To explore the factors that affect the teaching effect of medical statistics study for clinical postgraduates and to provide a reference for further improving teaching Quality. Methods Four hundred and eighty-nine students who had attended Medical statistics in 2013 Fall semester were surveyed by the self-designed questionnaire. The Logistic regression model was used to analyze the factors affecting the learning effect. Results A total of 489 questionnaires were distributed and 488 valid questionnaires were returned (the return rate was 99.80%). 71.11% (347/488) were entirely in favor of giving medical statistics course while 23.98% were relatively supportive. Statistics recognition, learning motivation, finishing homework and the satisfaction of learning were the factors that affect the grades. The OR values are 1.547, 1.723, 1.374, 1.433 for the above four factors respectively. The difference was statistically significant (P<0.05). Conclusion In medical statistics teaching, it can improve students' performance by introducing case study, simplifying the mathematical formula, combi-ning the theory and computer statistical software practice, and improving teaching methods, which helps improve the quality of teaching.
ABSTRACT
Objective To investigate the changes of plasma adiponectin concentration in type 2 diabetic patients with macrovascular complications.Methods Forty-nine cases of type 2 diabetic patients with macrovascular complications,fifty-four cases of type 2 diabetic patients without macrovascular complications and thirty-five healthy people were investigated.Their plasma adiponectin levels was assayed.Meanwhile,the levels of blood pressure,plasma glucose,lipids and C-peptide were measured.The plasma adiponectin levels among three groups were compared,and the factors affecting the plasma adiponectin were analyzed.Results The plasma adiponectin levels in the group of type 2 diabetes without macrovascular complications were lower than in the control group and were the lowest in the group of type 2 diabetes with macrovascular complications.The plasma adiponectin levels of these three groups were (16.37?3.03)mg/L,(6.69?4.42)mg/L,(4.08?3.24)mg/L,respectively.The differences among the three groups were statistically significant (P
