摘　　要： 目的探讨解偶联蛋白2(UCP2)在子宫内膜表达规律、围着床期变化及其与不孕的关系。方法分别应用原位杂交和Westernblot检测21例正常子宫内膜,22例不同原因不孕患者分泌期子宫内膜以及7例早孕蜕膜和绒毛UCP2mRNA和蛋白表达。结果子宫内膜组织内存在UCP2蛋白的表达,分泌期子宫内膜UCP2的表达高于增殖期子宫内膜,蜕膜组织UCP2的表达增加明显。在早孕绒毛滋养细胞层也存在UCP2的表达。与其他不孕妇女相比,输卵管积水者分泌期子宫内膜UCP2表达明显增加。结论UCP2可能参与子宫内膜蜕膜化过程,并可能参与胚胎着床调节,UCP2表达显著增加可能是子宫内膜拮抗活性氧族水平过度增高的代偿反应,反映了子宫内膜可能的氧化应激,后者可能是输卵管积水不孕的重要原因之一。 Objective To study the expression of uncoupling protein 2 (UCP2) mRNA and protein in the endometrium and its changes during periimplantation period in relation to infertility. Methods In situ hybridation and Western blotting were used to detect 21 endometrium specimens from normal cycling women during different menstrual phases, 22 secretory endometrium specimens from infertile women and 7 decidual and chorionic villus specimens. Result UCP2 mRNA and protein were detected in the endometrium and decidua besides, the trophoblast, and UCP2 level in the endometrium increased during pregnancy. Compared with normal women, women with hydrosalpinges had significantly stronger endometrial UCP2 expression in the mid-luteal stage. Conclusions UCP2 down-regulates reactive oxygen species and plays a role in the regulation of inflammatory events to prepare for embryo implantation. Strong endometrial UCP2 expression might be an important reason that hydrosalpinges affect embryo implantation.
