    [摘要] 目的 探讨2型糖尿病坐骨神经病变的超声显像特征。 方法 选取2017年2月～2018年2月在四川省内江市第一人民医院治疗的糖尿病伴坐骨神经病变患者70例(A组)，糖尿病无坐骨神经病变患者70例(B组)，同时选取健康者70名作为对照(C组)。采用高频超声观察各组坐骨神经的特征。 结果 A组神经被膜增厚粗糙比例明显高于B组和C组(P 0.05)；A组坐骨神经前后径(D1)、横径(D2)和横切面积(CSA)明显高于B组和C组(P 0.05)；A组男性患者D1、D2和CSA明显高于女性患者(P < 0.05)。 结论 高频超声可清晰显示坐骨神经参数，可为2型糖尿病坐骨神经病变诊断及治疗提供客观依据。

    [Abstract] Objective To investigate ultrasonography characteristics of type 2 diabetes mellitus with sciatic neuropathy. Methods From February 2017 to February 2018， in the First People's Hospital of Neijiang City， 70 cases of diabetic patients with sciatic neuropathy (group A)， 70 cases of diabetic patients without sciatic neuropathy (group B) were selected， and 70 healthy persons were selected as control (group C) at the same time. The characteristics of sciatic nerve in each group were observed by high frequency ultrasound. Results The proportion of nerve capsule thickening and rough in group A was significantly higher than those in group B and group C (P < 0.05)； the proportion of thickening and rough of the perineal membrane ......
