3阴茎定量感觉检测技术在神经损伤后性功能障碍评估中的应用*王飞翔**朱广友翁少峥沈彦沈寒坚司法部司法鉴定科学技术研究所,上海市法医学重点实验室(上海200063摘要目的探讨阴茎定量感觉检测技术(包括温度觉及振动觉在男性性功能障碍(包括勃起障碍及射精障碍临床检测中的应用价值。方法运用以色列产TSA-II型定量感觉分析仪,以极限法(limit法分别检测正常受试者(25例、神经损伤后勃起障碍患者(50例、神经损伤后射精困难患者(15例阴茎头部、左手示指的热觉阈值、热痛觉阈值及振动觉阈值,并同时计算阴茎头部相对感觉阈值,即阴茎头部不同感觉阈值分别与左手示指感觉阈值的相对比值。同时进行神经诱发电位检测,比较两种检测方法的检出率。应用统计学软件进行组间分析比较。结果神经损伤后勃起障碍患者组阴茎头部热觉阈值、热痛阈值及相对阈值明显高于正常对照组,两组之间比较有统计学意义(P<0.05;神经损伤后勃起障碍患者组阴茎头部振动觉阈值及相对阈值明显高于正常对照组,两组之间比较有统计学意义(P<0.05。神经损伤后射精困难患者组阴茎头部热觉阈值、热痛阈值及相对阈值明显高于正常对照组,两组之间比较有统计学意义(P<0.05;神经损伤后射精障碍患者组阴茎头部振动觉阈值及相对阈值明显高于正常对照组,两组之间比较有统计学意义(P<0.05。神经损伤后勃起障碍组与神经损伤后射精障碍组患者中阴茎定量感觉检测技术的检出率均高于神经诱发电位。结论(1阴茎定量温度觉检测技术是评价阴部神经特别是传导痛温觉的小神经(C类纤维结构和功能的有效方法。较之于传统的神经电生理检查,它能够更有效地检测出阴部小神经损伤或功能障碍,可以应用于性功能障碍的临床检测。(2阴茎定量振动觉技术是评价阴部神经特别是传导触压觉的神经(Aβ类纤维结构和功能的有效方法。较之于传统的神经电生理检查,它能够更精确地检测出阴茎局部神经损伤或功能障碍,可以应用于性功能障碍的临床检测。关键词定量感觉检测;勃起功能障碍;阴茎R698.1Penilequantitativesensorytestingtechnologyanditsapplicationinassessmentofsexualdysfunctionafternerveinjury*WangFeixiang**,ZhuGuangyou,ShenYan,ShenHanjiang,ZhouMinInstituteofForensicScience,MinistryofJustice,PRCShanghaiKeyLaboratoryofForensicScience,Shanghai200063,ChinaCorrespondenceauthor:Wangfeixiang,E-mail:wangfx@ssfjdtemperatureandvibrationinmalesexualdysfunction(includingerectiledysfunctionandejaculatorytheheatthresholds,heatpainthreshold,andvibrationthresholdoftheglanspenisandlefthandindexfingerweredetectedwithlimitmethodinnormalcontrolsubjects(25cases,erectiledysfunctionpatients(50casesafternerveinjury,anejaculationpatients(15casesafternerveinjury,andsimultaneouslycalculatetheglanspenisrelativesensorythreshold,namelytheglanspenisratiodifferentsensorythresholdrespectivelywiththelefthandindexfingersensorythreshold.atthesametimedetectthenerveevokedpotential.Analysisand*基金项目资助:科技部公益课题(编号:GY2015G-8**通讯作者,E-mail:wangfx@ssfjd·论著·4groupafternerveinjury,glanspenissensorythresholdwassignificantlyhigherthanthatinthenormalcontrolgroup,heatthreshold,heatpainthresholdandtherelativethreshold,therewassignificantdifferencebetweenthetwogroups(P<0.05;vibrationthresholdandrelativethresholdwassignificantlyhigherthanthatinthenormalcontrolgroup,therewassignificantdifferencebetweenthetwogroups(P<0.05.Inpatientswithanejaculationafternerveinjury,glanspenissensorythresholdwassignificantlyhigherthanthatinthenormalcontrolgroup,heatthreshold,heatpainthresholdandtherelativethresholdwassignificantlyhigherthanthatinthenormalcontrolgroup,therewassignificantdifferencebetweenthetwogroups(P<0.05;vibrationthresholdandrelativethresholdwassignificantlyhigherthanthatinthenormalcontrolgroup,therewassignificantdifferencebetweenth...
