摘要
目的 探讨超高频超声在2型糖尿病患者腓肠神经损伤中的应用价值.方法 选取有神经症状的糖尿病组、无神经症状糖尿病组和正常对照组的腓肠神经,分别为56条、64条和60条.应用22 MHz超高频超声测量并比较各组神经形态学指标,包括截面积（CSA）、厚/宽比（T/W ratio）以及最粗的神经束厚度（MT）等.结果 ①超声在各组中均可清晰显示腓肠神经的神经外膜、神经束膜和神经束等结构.②对照组、无症状组和症状组的T/W ratio和MT均依次增高,差异具有统计学意义（P＜0.05）,CSA在三组间差异无统计学意义（P=0.257）.结论 超高频超声可显示糖尿病患者的腓肠神经形态学特征,有望为糖尿病皮神经损伤提供一种新的形态学评价工具.
Objective To evaluate the morphological changes of sural nerve in patients with type 2 diabetes mellitus by hyperfrequency ultrasound.Methods Fifty-six sural nerves of symptomatic group,64 sural nerves of asymptomatic group,and 60 sural nerves of control group were identified by 22 MHz Ultrasound.The thickness/width （T/W） ratio,cross-sectional areas （CSA） and the maximum thickness of neuronal fascicles （MT） of the sural nerve were calculated in transverse sonograms.Results ①Ultrasound can clearly show these structures of sural nerve such as epineurium,perineurium and nerve bundles and so on.②In symptomatic group,asymptomatic group and control group,T/W ratio and MT were gradually increased,and the differences among the three groups were statistically significant （P〈0.05）.Whereas,there were no statistically significant differences in CSA among the three groups （P=0.257）.Conclusions22 MHz ultrasound may be a valuable tool in evaluating the diabetic cutaneous nerve neuropathy
