子宫内膜异位症(EMs)是一种病因未明,严重影响妇女生活的疾病。血管内皮生长因子(VEGF)可影响子宫内膜异位症的发生、发展,而VEGF基因中至少有30个单核苷酸具有多态性,目前学者们对-460 C/T、+405 G/C(也称为-634 G/C)、+936 C/T、-1154 G/A和-2578 A/C等的研究较多,这些位点可能通过影响VEGF的表达从而影响EMs。VEGF基因调控主要在转录及转录后水平,受药物、体内环境、体外环境等诸多因素的影响,其具体调控机制目前大多尚未明了。研究VEGF基因多态性及其调控途径以及对EMs的影响,将有助于学者们对EMs的发病机制作进一步了解,为探索治疗EMs的新方法提供思路。

【Abstract】Endometriosis seriously impacts on women′s life,whose etiology is still unknown.Vascular endothelial growth factor(VEGF)may affect the occurrence and development of endometriosis.VEGF gene has at least 30 single nucleotide polymorphisms,of which-460 C/T,+405 G/C(also known as-634 G/C),+936 C/T,-1154 G/A and-2578 A/C are more studied.These sites may impact on the development of endometriosis by influencing production of VEGF.The main gene regulation level of VEGF is in transcription and post-transcription,whose specific regulatory mechanism is not clear,and it can be affected by many factors,such as drugs,in vivo environment and in vitro environment.Research on the influence of VEGF gene polymorphisms and its regulation pathways on endometriosis will help scholars understanding the pathogenesis of endometriosis more so as to provide ideas of new ways to treat endometriosis.

子宫内膜异位症(EMs)是一种多因素(环境、基因、免疫等)共同作用所致的性激素依赖的妇科疾病,表现为具有生长能力及一定功能的子宫内膜组织(腺体或间质)出现在子宫腔被覆内膜和宫体肌层以外的其他部位。EMs影响10%的育龄妇女,其主要临床表现为慢性盆腔疼痛、痛经、不孕等。这些症状给患病妇女带来了严重的生理和心理的痛苦。尽管有关EMs的研究很多,但迄今为止,其发病机制仍未明确。目前公认的机制有经血逆流学说、内膜种植学说和机体免疫应答系统异常学说。郎景和教授提出经血逆流的“3A”模式,即逆流进入腹腔的子宫内膜组织在腹腔内种植、生长和转移必须通过黏附、侵袭、血管生成才能完成。……
