文题释义:

薄型子宫:是指子宫内膜厚度低于能够获得妊娠的阈厚度,即小于7 mm,可严重影响子宫的容受性。
子宫内膜:是指构成哺乳类子宫内壁的一层,分为致密层、海绵层和基底层3层。内膜表面2/3为致密层和海绵层统称功能层,受卵巢性激素影响发生周期变化而脱落。基底层为靠近子宫肌层的1/3内膜,不受卵巢性激素影响,不发生周期性的变化。子宫内膜对动情素和孕激素都起反应,因此可随着性周期(发情周期、月经周期)发生显著的变化。动情素可引起子宫肥大,孕激素可促使子宫内膜发生特殊的妊娠初期变化,或改变子宫内膜的性质,使之具有产生蜕膜的能力。子宫内膜覆盖着黏膜,由黏膜上皮与其下方的固有层所组成。黏膜上皮为柱状上皮、立方上皮或复层柱状上皮,动情素分泌时,各上皮细胞将长大、分裂使数目增多。固有层中黏膜上皮下方的部分称为机能层,上皮细胞进入其中形成子宫腺,并对动情素起反应。机能层的下层称为基底层,富有血管。

 

背景:乙醇化学损伤法能够有效对大鼠子宫进行薄型子宫内膜建模,薄型子宫内膜增殖相关蛋白表达减少,有助于研究薄型子宫内膜相关发生机制,为临床治疗提供指导。
目的:探索高浓度乙醇致薄型子宫后子宫内膜中波蛋白和血管内皮生长因子的表达变化。
方法:SD雌鼠右侧子宫缓慢注入0.3 mL体积分数95%乙醇建立薄型子宫模型,左侧子宫注入等量生理盐水作为对照侧。

结果与结论:与对照侧相比,大鼠损伤侧子宫内膜明显变薄,腺体数量减少,结构紊乱,波蛋白和血管内皮生长因子表达明显降低。说明体积分数95%乙醇损伤可有效建立大鼠薄型子宫内膜动物模型,且与增殖相关的蛋白在薄型子宫内膜中表达出现变化。

Abstract:

BACKGROUND: Ethanol chemical damage method can be used to establish thin endometrium rat model. Expression of proliferation-related proteins is decreased in thin endometrium animal model, which contributes to the study of thin endometrium-related mechanism and provides guidance for clinical treatment.
OBJECTIVE: To explore the changes in vimentin and vascular endothelial growth factor expression in rat models of high concentrations of ethanol-induced thin endometrium. 
METHODS: 0.3 mL 95% ethanol was slowly injected in the right uterus of female Sprague-Dawley rats to establish rat models of thin endometrium. An equal volume of physiological saline was injected into the left uterus as control sides.  RESULTS AND CONCLUSION: The thickness of endometrium in the injured uterus was significantly thinner than the control ones. Number of glands reduced, structure became disorder, and vimentin and vascular endothelial growth factor expression markedly diminished. These results suggest that 95% ethanol injury can effectively establish rat models of thin endometrium. Proliferation-related protein expression altered in the thin endometrium.
