1、徐州医学院硕士学位论文的表达情况。结果(1)机械痛行为学:胫骨骨髓腔内注射癌细胞后大鼠MWT逐渐降低,至造模后7d时较术前明显减低(p=O.05),同时自由行走痛评分逐渐增加,造模后7d时较术前明显增加(P2、犯缺损。(3)胫骨组织学:组织学检测发现所有的模型组大鼠胫骨髓腔内充满了肿瘤细胞,骨结构改变明显,而N组、SN组、SN200组未见骨结构改变。(4)免疫荧光染色:SN卟SG。组中DHSC和DRG内未见明显CCL2表达,BNⅡ组中DHSC和DRG内趋化因子CCL2大量表达,应用加巴喷丁后BGⅡ组DHSC和DRG内CCL2的表达量较BNⅡ组减少(P.<0.05),但是不能完全抑制。结论加巴喷丁可以减轻胫骨癌痛大鼠的机械痛敏,其脊髓机制可能与抑制DHSC和DR(3中趋化因子CCL2的分泌有关。关键词骨癌痛;加巴喷丁;背根神经节;脊髓背角;趋化因子CCL2徐州医学3、院硕士学位论文EffectofgabapentinonmechanicalaHodyniaandthespinalmechanisminaratmodeloftibialbonecancerpainAbstractobjecfiveToobservetheeffectofgabapentinonmechanicalallodyniainaratmodeloftibialbonecancerpain,andinvestigateifgabap删nCaninhibitthesecretionofchemokineCCL2inDHSCandDRGMethodsP4、artITotalof42femaleSprague—Dawleyratswererandomlydividedinto7groups(n=6each):naivegroup(groupN),shamoperation+NS(groupSN),shamoperation+GBP200mg/kg(groupSG200),BCP+NS(groupBN),BCP+GBP50mg/kg(groupBG50),BCP+GBP100mg/kg(groupBGl00),andBCP+GBP200mg/kg(groupBG200).TheratsingroupN,SNan5、dBNreceived5mlnormalsalineandtheratsingroupSG200,BG50,BGl00andBG200received200,50,100and200mg/kgdoseofGBPviafeedingfromday7to13afteroperationperday,respectively.Mechanicalwithdrawalthreshold(MWT)oftherightpawandbehavioralassaysforambulatorypainweremeasul'cdjustbeforeoperationandon6、days1,3,5,7,8,10,12and14afteroperation.Atlastthetibiawasstainedwithhematoxylinandeosin(HE)toverifycancercellinfiltrationandbonedestruction.Part1ITotalof32femaleSprague-Dawleyratswererandomlydividedinto4groups(n=8each):shamoperation+NS(groupSNII),shamoperation+GBP(groupSG)O,BCP+NS(7、groupBNn),BCP+GBP(groupBGⅡ).Themechanicalwithdrawlthreshold(MWT)WaSmeasuredbeforeoperationand1,3,5,7daysafteroperation.Eachgroupaccepteddifferentdrugtherapiesafterlhon7dayswhentheN【WTwasmeasured.GroupSNIIandBNnweregavagedwith4ml/kgNS,andGroupSGnandBG]1weregavagedwith200mg/kgGBPdis8、solvedin4ml/kgNS.MWTWastestedon2,
