子宫复旧不全是产褥期常见的疾病，可导致近期并发症和远期并发症，严重影响妇女健康。随着国内外学者对其研究的不断深入，发现甾体激素及其受体、细胞凋亡、血管活性因子等诸多因素共同调控产后子宫复旧过程。子宫收缩、胶原降解、细胞凋亡、子宫内膜修复是子宫复旧过程中的重要步骤，是影响子宫复旧的重要因素。子宫内膜干细胞具有高度增殖、自我更新和分化潜能，可能会成为今后研究的热点。“,”Incomplete puerperal involution of uterus is a common disease,which can lead to short-term complications and long-term complications.Incomplete puerperal involution of uterus has been estimated to affect mothers.During recent years many experts have been doing a lot of basic and clinical researches,and found that endometriosis is closely related to steroid hormone and its receptor,various vasoactive substances, angiogenesis factor,stem cells,and regulation and control of the process of collagen degradation,endometrial repair.The uterine contraction,collagen degradation, apoptosis and endometrial repair are an important step in uterine involution,which are important influence factors of involution of uterus.Endometrial stem cells have high proliferation, self-renewal anddifferentiation potential, which may become a research focus.
