2、/c小鼠随机分为正常组、假手术组及卵巢切除组,各1O只。ELISA法检测血清雌二醇(E2)水平,双能X线骨密度仪检测股骨骨密度(BMD),流式细胞仪胞内外双染色法检测脾脏单个核细胞Thl/Th2/Thl7/Treg亚群比例。结果:与正常小鼠及假手术小鼠比较,卵巢切除小鼠E2、BMD显著降低(P<0.05),T}l1、Thl7亚群比例明显升高(P3、关(P<0.05)。结论:T细胞亚群偏移参与了雌激素缺乏导致的骨丢失,逆转T细胞亚群失衡可能成为防治雌激素缺乏骨丢失的有效靶点与途径。[关键词]雌激素缺乏;T细胞亚群;骨代谢;骨丢失;相关性ExperimentalstudyofcorrelationbetweenT-cellparadigmandbonelossinducedbyestrogendeficiencyGAOXiu—Lian,XINGMei—Yun,WANGLi,GUOYu-Qi,ZHOUXian-Bin,ZHANGQiao—Feng,ZHANGHong—Hai,YAOCheng—Fang,JIANGGuo-4、Sheng,LIXia.KeyLaboratoryforTumorImmunityandTraditionalChineseDrugImmunity,InstituteofBasicMedicine,ShandongAcademyofMedicalScience,Jinan250062,China[Abstract]0bjective:TodemonstratetherelationshipbetweentheThl/Th2/Th17/Tregparadigmandthebonelossinducedbyestrogendeficiencyandlookingforpot5、entialtargetforclinicaltreatment.Methods:30BALB/cmiceweredividedrandomlyintothenormalcontrolgroup,theshamoperationgroup,andtheovariectomygroup.Theserumestradiol(E2)wasassessedbyELISA.Bonemineraldensity(BMD)ofthighbonewasmeasuredwithdualenergyXrayabsorptiometry.Meanwhile,theT—cellsubsets(T6、hl:CD4TNFc~,Th2:CD4IL_4,Thl7:CD4IL一17A,Treg:CD4CD25Foxp3)inspleenlymphocyteswereanalyzedbyflowcytometry.Results:Comparedwiththenormalgroupandtheshamoperationgroup,bothE2andBMDintheovariectomygroupdecreasedsignificantly(P<0.05).ThepercentageofThlandThl7subsetincreasedwhilethepercentageofTh7、2andTregdecreasedsignificantlyinovariectomymicecomparedwithshamoperationmice.CorrelationanalysisshowedthatBMDwaspositivelyrelatedtoE2levelandthepercentageofTh2andTregsubset;however.BMDwasnegativelyrelatedtothepercentageofThlandThl7subset(P<0.05).Conclusion:Conclusio
