2、r,BDNF)表达的影响。方法将绿色荧光蛋白转基因小鼠在T9、T1。间行SCT,随机分为电针(EA)组、对照组,每组9只小鼠。EA组于术后第1d开始电针刺激至第13d结束,对照组仅做SCT。术后28d时,取小鼠大脑皮质运动区脑组织,用免疫组化、原位杂交、逆转录一聚合酶链式反应、酶联免疫吸附试验检测皮质运动区BDNF的表达变化。结果BDNF蛋白和mRNA阳性产物主要表达于皮质运动区神经元。EA组、对照组皮质运动区BDNF蛋白表达分别为(1973.41±194.71)pg/mg、(1615.22±137.21)pg/mg,差异有统计学意义(P3、计学意义(P>O.05)。结论脊髓损伤后督脉电针刺激能够有效增加小鼠大脑皮质运动区BDNF蛋白表达,这有助于揭示电针刺激促进脊髓损伤修复的机制。【关键词】脊髓全横断电针刺激脑源性神经营养因子小鼠EffectsofElectrOacupunctureof“GovernorVessel”AcupointsonChangesofBDNFintheCorticalMotorAreaofMicewithSpinalCordTransectionZHANGXiang一,ZOUYu,ZHAOYa,WANGTing—h“dw,ZHANGWe~△.1.DepartmentofHistologyandEm4、bryology,WestChinaSchoolofPreclinicalandForsc,S““University,Chengdu610041,China;2.InstituteofNeuroscience,KunmingMedicalCollege,Kunming650031,China;3.TranslationalNeuroscienceCenter,WestChinaHospital,SichuanUniversity,Chengdu610041。China△Correspondingauthor,E-mail:zhangwi25091@gmail.corn[Abstrac5、t]ObjectiveToinvestigateeffectsofelectroacupunctureof“GovernorVessel”acupoints0nchangesofbrainerivedneurotrophicfacotr(BDNF)inthecortexareaofmicewithspinalcordtransection(SCT).MethodsGFPmicesweremadespinalcordtransectionbetweenT9andT1o,andthendividedintoe1ectroacuDuncturegroup(EAgroup)andcontrol6、group;mieesofEAgrouphadbegivenEAfrom1daypostoperationto14daypostoperation,however,mieesofcontrolgrouphadonlySCT.Immunohistochemistry,insituhybridization,RT—PCRandELISAwereperformedtoobservechangesofBDNFinthecorticalmotorareaofEAandcontrolgroup.ResultsAt28dpostoperationtheproteinexpressionofBDNFi7、nthecortexareaofEAgroupandcontrolgroupwas(1973.41±194.71)pg/kgand(1615.22±137.21)pg/kgrespectively,andtherewasstatisticaldifferencebetweenthem(P
