1、中文摘要目的研究多囊卵巢综合征(PCOS)不孕患者血清白血病抑制因子(LIF)水平及卵巢组织中LIF和其受体(LIFR、gpl30)表达是否异常,从整体及细胞水平探讨卵巢局部调节因子LIF及其受体在PCOS排卵障碍中的作用。方法应用化学发光法及ELISA法测定22ffIIPCOS患者和20例输卵管性不孕患者血清性激素及血清LIF水平;应用免疫组织化学方法检测以上患者卵巢组织LIF及其受体的蛋白表达。结果1、PCOS组廊清中LIF的水平明显低于对照组(尸2、LIF在PCOS组颗粒绣脆中星弱黼性表达,鞠显院对照缝嚣(PO.05)。3、LIFR在PCOS组颗粒细胞中呈阳性或强阳性表达,与对照组比较蠢漫著差吴(P>O。05);闻覆细胞均璺弱阳性表达,比对照缝弱(P<0.05);在卵泡膜细胞的表达两组无龆著差异(P>O.05)。4、gpl30禚两组颗粒细胞中的表达均弱,无盟著差异(P>0.05),在卵泡膜及间矮细胞无表达。5、在两篷均可发现,LIF在颗粒纲腌中酶表达均是隧郭漉愈大纛愈强。LIFR在PCOS组颗粒细胞的表达3、无论卵泡大小均表现较强染色,未发现其染色随卵泡愈大简愈强的趋势;在对照组中,LIFR在颗粒细您的表达圈LIF类麓,照郛泡增大染惫增强。结论PCOS患者血清LIF水平的异常及LIF与其受体的调节失常可能是导致PCOS排卵障碍的一个黧要因素。关键词多囊卵巢综合征,岛盘病{;}每铡霭子,岛4、薤病静裁霞子受体(LIFR),gpl30ABSTRACTobjeetiveTodeterminewhethertheinfertilepatientswithpolycysticovariansyndromearerelatedtodyre5、gulationofthelevelsofserumleukaemiainhibitoryfactor(LIF)andexpressionofLIFanditsreceptorsinovaries,andtocomparegeneralandlocalactionandtoexplainfurtherthefailureoffolliculardevelopmentregulatedbyovarianlocalfactors,suchasLIFanditsreceptorsinpolycysticovariansyndr6、ome.Methods22infertilitypatientswithpolycysticovariansyndromeand20controlpatientswereincorporatedintothestudy.ThelevelsofserumLIFandgonadalhormonesweredetectedbyELISAandChemiluminescencerespectively.Expressionofleukaemiainhibitoryfactoranditsreceptorsweremeasured7、byimmunohistochemistry.Result1.Them.eanlevelofserumLIFofthestudygroupwasobviouslylowerthanthatofthecontrolgroup,P<0.05.andnegativelycorrelatedwit量lE2andL}薹,FSHratio.butcorrelatedwithoutPandT.2.StainingforLIFingranulosacellsofpolycysficovarieswassignificantlyweake8、rthanthatinthenormalovaries(P《O.001).whereassimilarinthecaandintersititialcells(j》O.05).3.StainingforLIFRininterstitialcellswassignificantlyweakerinpolycysticovariesthanthatinthenormalovaries(P0.05).Granulosacellsha9、dveryintensestainingforLIFR,butstainingforLIFRinthecacellswereveryweekinpolycysticovaries.霹.Intwogroups,thegranulosacellshadweakstainingforgpl30(P>O.05),andint
