粒细胞集落刺激因子对子宫内膜作用的研究

子宫内膜容受性(ER)是胚胎着床的重要因素,薄型子宫内膜(thin endometrium)是导致ER差的原因之一。薄型子宫内膜的发病机制、内膜厚度及血流灌注都与其胚胎移植的成功率息息相关,因此薄型子宫内膜的治疗显得尤为重要。近年来的一些研究证实了粒细胞集落刺激因子(G-CSF)在子宫内膜修复方面起到了积极的促进作用,探讨总结粒细胞集落刺激因子对子宫内膜的修复机制对胚胎移植适应症及临床应用具有重要意义。     

Pregnancy outcome following frozen embryo transfer after artificial cycle or treatment by clomiphene citrate

The optimal method to prepare endometrium before frozen embryo transfer (FET) is not yet established. We retrospectively studied 4496 FET and detailed pregnancy and miscarriage rates in three groups of patients according to the endometrium preparation they have followed before their successive FET: clomifene citrate (CC, group 1), artificial cycle (AC, group 2) or switch between CC and AC (group 3). The overall pregnancy rates per transfer were 24.3, 20.8 and 17.3% while the miscarriage rates reached 23.2, 29.8 and 42.5%, respectively. Group 1 experienced the highest ongoing pregnancy rate (18.6%), the lowest being observed in group 3 (10.0%, p?相似文献   

Thin endometrium after radiation therapy as an unresolved treatment challenge: a case report

Receptive endometrium is essential for successful implantation and ongoing pregnancy. Significant health issues and associated therapies, especially oncologic therapies, have potential to negatively impact future fertility in young women. Irradiation and chemotherapeutic alkylating agents are known to cause ovarian failure in most females; however, less well is characterized the impact of irradiation on uterine development and integrity. With an increasing number of cancer survivors, women are seeking infertility treatment after such therapies. Here, we present a young woman who developed ovarian failure after the treatment of acute myeloid leukemia with bone marrow transplant and preceding irradiation and chemotherapy and who was diagnosed with thin endometrial lining while seeking infertility therapy.     

Localization and variable expression of G alpha(i2) in human endometrium and Fallopian tubes

BACKGROUND: Heterotrimeric G proteins take part in membrane-mediated cell signalling and have a role in hormonal regulation. This study clarifies the expression and localization of the G protein subunit G alpha(i2) in the human endometrium and Fallopian tube and changes in G alpha(i2) expression in human endometrium during the menstrual cycle. METHODS: The expression of G alpha(i2) was identified by Polymerase chain reaction (PCR), and localization confirmed by immunostaining. Cyclic changes in G alpha(i2) expression during the menstrual cycle were evaluated by quantitative real-time PCR. RESULTS: We found G alpha(i2) to be expressed in human endometrium, Fallopian tube tissue and in primary cultures of Fallopian tube epithelial cells. Our studies revealed enriched localization of G alpha(i2) in Fallopian tube cilia and in endometrial glands. We showed that G alpha(i2) expression in human endometrium changes significantly during the menstrual cycle, with a higher level in the secretory versus proliferative and menstrual phases (P < 0.05). CONCLUSIONS: G alpha(i2) is specifically localized in human Fallopian tube epithelial cells, particularly in the cilia, and is likely to have a cilia-specific role in reproduction. Significantly variable expression of G alpha(i2) during the menstrual cycle suggests G alpha(i2) might be under hormonal regulation in the female reproductive tract in vivo.     

定坤丹治疗子宫内膜薄型不孕的临床效果

目的 观察定坤丹治疗子宫内膜薄型不孕的临床效果,为优化子宫内膜薄型不孕的治疗方案提供参考。方法 选取187例子宫内膜薄型不孕患者,在保证组间基本特征匹配原则上,利用计算机软件产生的随机数,按照1∶1的比例分为对照组(93例)和观察组(94例)。对照组给予雌二醇+地屈孕酮干预,观察组在对照组的基础上加用定坤丹。比较治疗3个周期后两组患者的子宫内膜厚度、孕激素浓度及临床妊娠率。结果 观察组患者排卵期平均子宫内膜厚度显著高于对照组(P<0.01),黄体期孕激素浓度显著高于对照组(P<0.01),累计临床妊娠率显著高于对照组(P<0.05)。结论 定坤丹可以明显改善子宫内膜薄型不孕患者排卵期子宫内膜厚度,提高黄体功能,改善妊娠结局。     

诺舒子宫内膜去除术治疗子宫腺肌病致月经过多的临床研究

目的探讨针对子宫腺肌病致月经过多患者采用诺舒(NovaSure)子宫内膜去除术治疗的临床意义。方法选取2012年3月至2013年6月因子宫腺肌病在番禺中心医院行NovaSure子宫内膜去除术的患者29例为研究组,行宫腔镜下子宫内膜电切术的患者27例为对照组,所有患者术后门诊定期随访,根据月经失血评估图(pictorial blood loss assessment chart,PBAC)评分判定术前出血情况、手术时间、术中出血量、术后闭经率、月经减少率和月经改善率。结果研究组手术时间、术中出血量少于对照组(P0.05);两组术后并发症率、治疗有效率比较差异无统计学意义(P0.05)。结论 NovaSure子宫内膜去除术是治疗子宫腺肌病致月经过多的有效方法。
