Objective To compare the efficacy of empagliflozin and DDP4 inhibitors in the treatment of type 2 diabetes mellitus.Methods With Computer,we retrieval PubMed,Cochrane Library,EMbase,CNKI,CBM and Wanfang database to find all of the randomized controlled trials about the effectiveness and safety of empagliflozin and DDP4 inhibitors in the treatment of type 2 diabetes mellitus.The retrieval time was from the establishment of database to March,2016.References screen were performed manually.Meta-analysis was carried out using RevMan 5.2 software.Results A total of five studies included 1935 cases.The Meta analysis results showed that:HbA1c level (MD =-0.07,95％ CI:-0.13--0.01,P ＜0.05),fasting blood glucose (MD =-16.73,95％ CI:-21.02--12.43,P ＜ 0.01),weight loss level (MD =-2.43 95％ CI:-2.68--2.19,P ＜ 0.01) in the two groups showed statistically significant differences.Empagliflozin group was better than DDP4 inhibitors group in reducing HbA1c level,fasting blood glucose,weight loss level.Safety:hypoglycemia between the two groups were similar (OR =0.86,95％ CI:0.46-1.6,P ＞ 0.05).Empagliflozin group's genital tract infection rate was statistically significant higher than that of DDP4 inhibitors.(OR =2.85,95％ CI:1.71-4.76,P ＜ 0.01).Conclusion Empagliflozin can effectively reduce the fasting blood glucose,HbAIc,and body weight,but increase the incidence of genital infection compare with DDP4 inhibitors.

Objective To study the effect of different types of dyslipidemia on heart rate variability in patients with type 2 diabetes.Methods Cohort study was carried out at Renmin Hospital of Wuhan University during January 2014 to May 2016.Total 725 patients with type 2 diabetes were recruited,including 231 patients without dyslipidemia and 494 patients with dyslipidemia.Clinical parameters were collected from electronic medical records system.Using variance analysis,chi square test,Pearson correlation analysis and partial correlation analysis,we explored an association of different types of dyslipidemia and heart rate variability in patients with type 2 diabetes.Results TG,LDL-C,HDL-C,TG + HDL-C group significantly decreased heart rate variability compared group without dyslipidemia (P ＜ 0.05).But the partial correlation analysis showed that only atherogenic index of plasma and Triglyceride (TG) were negatively correlated with heart rate variability,HDL cholesterol was positively correlated with heart rate variability,and the difference was statistically significant (P ＜ 0.05).Conclusion Triglyceride (TG),atherogenic index of plasma(AIP),HDL cholesterol were related to the reduction heart rate variability in patents with type 2 diabetes.
