Abstract:
Objective To study the effect of acarbose on vascular endothelial function in patients with impaired glucose tolerance (IGT).Methods Fifty-six cases with IGT were chosen by OGTT,and they were divided into control group(27 cases) and therapy group(29 cases) by systematic sampling.The patients in control group were received placebo,the patients in therapy group were given acarbose 25-50 rug,3 times daily for 12 weeks.The body mass index (BMI),blood fat,fasting blood glucose (FPG),fasting insulin (FINS),glycosylated hemoglobin (HbA1c),high sensitivity C-reactive protein (hs-CRP),von Willebrand factor (vWF),2 h post-meal glucose (2hPG),2 h post-meal insulin (2hINS) and brachial artery endothelium-dependent dilation (EDD) was detected before and after treatment in two groups.Results Compared with that before treatment,BMI,2hPG,2hINS,HbA1c,hs-CRP and vWF were decreased and brachial artery EDD was improved after treatment in therapy group[ (24.69 ± 2.62) kg/m2 vs.(22.02 ± 2.59)kg/m2,(9.26 ± 1.02) mmol/L vs.(7.43 ± 0.95) mmol/L,(42.17 ± 9.98) U/L vs.(34.76 ± 9.86) U/L,(6.03 ±0.67)％ vs.(5.37 ±0.56)％,(5.45 ± 1.93) mg/L vs.(4.52 ± 1.55) mg/L,(187.22 ±26.57)％ vs.(165.13 ± 23.86)％,(6.08 ± 1.22)％ vs.(7.94 ± 1.25)％ ] (P ＜ 0.05 or ＜ 0.01).There was no significant difference before and after treatment in control group (P ＞ 0.05).Conclusion Acarbose can improve brachial artery EDD in patients with IGT by increasing insulin sensitivity and decreasing postprandial hyperglycemia and inflammatory factor,which delays the progression of diabetic mellitus and atherosclerosis.
