A波在2型糖尿病周围神经病变诊断中的应用价值

目的：探讨A波在2型糖尿病周围神经病变诊断中的应用价值。方法：83例2型糖尿病（DM）患者进行正中神经和胫神经F波检测,观察A波出现情况。结果：83例DM患者中共有53例检出周围神经损害,占63.86%;F波合计异常52例,占62.67%,明显高于对照组（P〈0.05）;DM组A波检出率明显高于对照组（P〈0.05）;F波异常的DM组和对照组A波检出率比较,差异无统计学意义（P〉0.05）;胫神经A波检出率明显高于正中神经（P〈0.05）。结论：临床上当患者出现A波时,提示患者可能存在脱髓鞘性神经病变,A波对诊断早期糖尿病周围神经病变可能具有重要参考价值。

APPLICATION VALUE OF A WAVE IN DIAGNOSIS OF TYPE 2 DIABETIC PERIPHERAL NEUROPATHY

Objective：To investigate the application value of A wave in diagnosis of type 2 diabetic peripheral neuropathy.Methods：F wave was detected at median nerve and tibial nerve of 83 patients with type 2 diabetes mellitus（DM）,and the appearance of A wave was observed.Results：Among 83 patients,the peripheral nerve injury accounted for 63.86%（53/83）;the total abnormal F wave accounted for 62.67%（52/83）,which was obviously higher than that of control group（P 0.05）.In DM group,the frequency of A wave was obviously higher than control group（P 0.05）;but there had no statistical difference about frequency of A wave between DM group and control group that F wave was abnormal（P 0.05）.The frequency of A wave at tibial nerve was obviously higher than median nerve（P 0.05）.Conclusions：Appearance of A wave suggests demyelinating neuropathy,and A wave may has important reference value for diagnosising diabetic peripheral neuropathy early.
