2、L·kg/次治疗,在造模后第1、3.7、15、30d等时间点各处死大鼠10只,取腰段脊髓做脊髓背角NR2B受体测定,并进行分析。【结果]两组大鼠造模后第1d的PWTs明显低于造模前的PWTs值(P3、.69+0.58g,差异有统计学意义(P<0.01)。两组间比较,造模后第7、15d时,温经通痹汤组大鼠PWTs值均高于模型组大鼠的PWTs值,差异有统计学意义(P≮0.05)。与造模后1d时比较,模型大鼠脊髓背角NR2B的亚基表达在术后第3、7、15、30d差异有统计学意义(P<0.01);温经通痹汤组脊髓背角NR2B的亚基表达只有在造模后第7、15、30d有非常显著性差异(P<0.01)。两组组间比较,温经通痹汤组脊髓背角NR2B的表达在3、7、15d显著低于对照组,差异有统计学意义(P4、痹汤能有效提高坐骨神经损伤大鼠(CCI模型)的痛阈,并在一定治疗时间内存在镇痛累积效应。温经通痹汤在早期较好地抑制脊髓背角NK2B的表达,与改善痛闽的时点吻合,初步说明温经通痹汤提高痛阈与调节脊髓背角NR2B亚基的表达有关。关键词:温经通痹汤;坐骨神经损伤;痛阈;NR2B中图分类号:R331文献标识码:A文章编号:1005—5509(2014)01—00l7一o5TheValueofWenJingTongBiDecoctiononPainThresholdofSciaticaandExpressionofNR2BinSpinalCordZhaoWensheng’,ShiHui,ZhouXu5、wen.etal.7eAnnesthesiologyDepartmentoftheSecondAffiliatedHospitalofZhejiangTraditionalChineseMedicalUniversity,Hangzhou(310005),China,"2.ThePhysiotherapyDepartmentofTheSecondAffiliatedHospitalofZhed凡gUniversityCollegeofMedicineAbstract:【O~ective]TostudytheefectofWenJingTongBiDecoctiononpainthresho6、ldofsciaticaandexpressionofNR2Binspinaldorsalhom.【Methods】100Spraque—Dawleyratswererandomlydividedinto2groups:Modelgroup(n50)andWenJingTongBiDecoctiongroup(n5O).Theleftsciaticnerveofratwasisolatedandconstricted.Afteroperation,theWenJingTongBiDecoctiongroupwastreatedwith10ml’kg一twiceaday;andtheMode7、lgroupwasadministeredwiththesamedoseofsaline.Pawwithdrawalthresholds(PWTs)areusedasthepainthreshold.AlratswereobservedPWTsandexecutedatthepre—operationandthe1st,3rd,5th,7th,15th,30thdayafteroperation.Thelumbarspi
