摘　　要：目的探讨瞬时波强(WI)技术评估2型糖尿病(T2DM)患者胫前动脉弹性的临床意义。方法应用WI技术检测31例糖尿病患者及25例健康对照者的胫前动脉瞬时波强各相关指标,主要有负向波面积(NA)、僵硬度指数(β)、血管压力应变弹性系数(Ep)、顺应性(AC)、增大指数(AI)及脉搏波传导速度(PwVβ)等。结果糖尿病组患者胫前动脉NA、β、Ep、AI、PWVβ均高于对照组(P<0.05),AC无明显差异(P>0.05)。结论糖尿病患者胫前动脉存在动脉硬化,WI技术可以用来评估糖尿病患者肌性动脉的弹性。Objective To investigate the clinical significance of wave intensity （WI） technique in evaluating the e- lasticity of anterior tibial artery in patients with type 2 diabetes mellitus. Methods The negative area of wave intensity and arterial elasticity indexes were detected in 31 cases of type 2 diabetes mellitus and 25 healthy people. The indexes include negative area（NA）, stiffness parameter（β）, pressure strain elasticity modulus（Ep）, arterial compliance（AC）, argumentation index（AI） and one point pulse wave velocity （PWVβ）. Results Compared with control group, NA, Ep, β,PWVβ and AI levels were higher（P〈0. 05）, there was no significant difference of AC between two groups （P〉0.05）. Conclusions The abnormal elasticity of anterior tibial exists in type 2 diabetes mellitus,WI technique can be used to evaluate the elasticity of muscular arteries.
