摘要
目的观察伴微量白蛋白尿(MA)空腹血糖受损(IFG)个体血管内皮细胞功能变化,探讨其大血管病变危险性增加的相关危险因素。方法选择IFG伴MA(IFG-MA)患者16例,IFG伴尿白蛋白正常(IFG-NA)患者16例,正常对照(NC)者18例。采用彩色多普勒超声显像技术测定3组内皮细胞依赖性血管舒张功能(EDV)以及非内皮细胞依赖性血管舒张功能(EIV),全自动生化分析仪测定血生化。结果IFG-MA组EDV((7.8±3.0)%)和IFG-NA组EDV((9.2±3.7)%)均较正常对照组((13.6±4.2)%)降低(P均<0.05),且IFG-MA组EDV受损程度重于IFG-NA组(P<0.05);3组间EIV差异无统计学意义(P>0.05)。IFG-NA组和IFG-MA组血甘油三酯(TG)分别为(1.6±1.2)mmol/L、(1.8±1.1)mmol/L,血游离脂肪酸(FFA)分别为(654±198)μmol/L、(988±209)μmol/L,均高于正常对照组((1.5±0.6)mmol/L、(352±159)μmol/L)(P<0.05或0.01)。结论伴MA的IFG个体血TG、血FFA水平升高及伴随的血管内皮细胞功能受损可能是大血管病变危险性增加的相关因素。
Aim : To observe changes of endothelial function in subjects of impaired fasting glycaemia (IFG) with microalbuminuria (MA) and to explore its related factors of increasing macrovasular risk. Methods: A total of 16 cases of impaired fasting glycaemia with microalbuminuria(IFG-MA) and 16 cases of IFG without MA (IFC-NA) and 18 cases of healthy volunteers (NC) were enrolled. High-resolution uhrasonography was applied to measure the vasodilation in brachial artery diameter for endothelium-dependent vasodilation(EDV) and endothelium-independent vasodilation(EIV). Results: EDV was impaired in IFG-MA group (7.8 ± 3.0) % and IFG-NA group (9.2 ± 3.7) % compared with NC group ( 13.6 ± 4.2)% (P 〈0.05). EDV in IFG-MA group was lower than that in IFG-NA group(P 〈0.05). There was no significant difference in EIV among three groups ( P 〉 0.05 ). Compared with serum triglyceceride (TG) ( ( 1.5 ± 0.6) mmoL/L) and plasma free fatty acid (FFA) ( (352 ± 159) umol/L) in NC group TG in IFG-NA group and IFG-MA group ( ( 1.6 ± 1.2) mmoL/L, ( 1.8 ± 1.1 ) mmoL/L) and FFA in IFC-NA group IFC-MA group (654 ± 198 ) μmoL/L, (988 ± 209 ) μmoL/L) were higher (P 〈0.05 or0.01 ). Conclusion: IFG-MA subjects show higher TG and FFA level and the endothelial dysfunction may be related factors that increase cardiovascular risk in the subjects.
