摘  要:目的探讨定量温度觉阈值检查(QTT)在糖尿病周围神经病诊断中的应用价值。方法选取有神经系统症状的169例糖尿病患者[根据病程分为≤5年(69例)和〉5年(100例)2个亚组;根据神经传导检测(NCS)是否存在异常分为正常组(45例)和异常组(124例)],并选取年龄匹配的53名健康对照,进行手及足背的冷感觉阈值(CT)、热感觉阈值(WT)、冷痛觉阈值(CPT)、热痛觉阈值(WPT)测定。结果病程≤5年糖尿病组的手及足背CT[分别为(29.6±1.4)、(26.5±4.3)℃]、WT[(35.9±3.0)、(41.3±4.0)℃]高于健康对照组[手背CT(30.2±1.2)℃,足背CT(29.1±1.5)℃;手背WT(35.0±1.9)℃,足背WT(36.5±1.5)℃;t=3.27、6.63、2.80、8.61,均P〈0.05],病程〉5年糖尿病组[手背CT(28.2±4.0)℃,足背CT(23.1±7.9)℃;手背WT(37.0±4.7)℃,足背WT(42.6±4.2)℃]高于病程≤5年糖尿病组(t=4.09、4.63、2.55、2.68,均P〈0.05),NCS正常的糖尿病组[手背cT(29.5±1.8)℃,足背CT(27.0±4.6)℃;手背WT(35.0±1.9)℃,足背WT(40.9±3.8)℃]高于健康对照组(t=3.22、4.17、3.51、9.95,均P〈0.01),差异具有统计学意义。糖尿病组QTT的异常率比NCS的异常率更高,病程〉5年糖尿病组NCS、QTF的异常率较病程≤5年糖尿病组高;糖尿病组WT异常率(86.4%,146/169)高于CT异常率(68.1%,115/169Χ^2=15.49,P〈0.01),足背刺激QTT的异常率高于手背刺激QTT的异常率。与健康对照组相比,糖尿病患者的痛觉阈值较高。结论QTT较常规NCS在糖尿病周围神经病诊断中具有更高的灵敏度,可作为常规NCS的必要补充。下肢热感觉阈值检查是诊断糖尿病周围神经病的敏感指标。Objective To investigate the significance of quantitative thermal testing (QTT) in the diagnosis of diabetic peripheral neuropathy. Methods One hundred and sixty-nine diabetic patients with neurological deficit (DM group) and 53 age-matched healthy controls underwent the determination of cold threshold (CT) , warm threshold (WT) , clod pain threshold (CPT) , warm pain threshold (WPT) in both dorsum of hand and dorsum of foot. DM group were divided into subgroups with a course of disease 〉 5 years or with a course of disease ≤5 years, or divided into subgroups with normal or abnormal nerve conduction study (NCS). Results CT and WT of DM group with a course of disease ≤5 years((29.6 ± 1.4), (26. 5 ±4. 3) ℃ ; (35.9 ±3.0) , (41.3 ±4.0) ℃ ) were higher than the health controls' ( (30. 2± 1.2), (29. 1±1.5) ℃ ; (35.0 ± 1.9), (36. 5± 1.5) ℃, respectively; t =3.27, 6. 63, 2. 80, 8.61, all P 〈 0.05 ). The CT and WT of DM group with a course of disease 〉 5 years' ( (28.2±4. 0) , (23. 1 ± 7.9) ℃ ; (37.0 ± 4. 7) , (42. 6± 4. 2 )℃ , respectively) were higher than the DM group with course of disease ≤ 5 years(t=4.09, 4.63, 2.55, 2.68,all P〈0.05). CTand WTofthe normal NCS group((29.5 ±1.8), (27.0±4. 6) % ; (35.0 ± 1.9), (40. 9 ±3.8) ℃, respectively) were higher than the healthy controls' , and the difference was significant ( t = 3.22, 4. 17, 3.51, 9.95, all P 〈 0. 01 ). The frequency of abnormal QTT in DM group was higher than that of NCS in DM group. The QTT and NCS of DM group with a course of disease 〉 5 years were higher than these in DM group with a course of disease ≤5 years; the frequency of abnormal WT in DM group(86. 4% , 146/169)was higher than that of CT in DM group (68.1%, 115/169, Χ^2 = 15.49, P 〈 0. 01 ), the frequency of abnormal QTT in the dorsum of foot in DM group was higher than that in the dorsum of hand in the DM group.
