调经孕育方药对排卵障碍性不孕者子宫内膜感受态的影响

目的研究调经孕育方药对排卵障碍性不孕者子宫内膜感受态早孕相关因子方面表现的影响.方法采用服用方药前后自身对照的方法,27例受试者分别于LH-2、LH 7、LH 10进行子宫内膜活检取材,进行免疫组织化学的分析.结果服用方药后,19种早孕相关因子中的18种其表达强度均有不同程度的增强,表明子宫内膜感受态明显改善,促进内膜中活性物质活跃和活性显著增加,认为内膜感受态的协调改善是实现助孕作用的重要基础.结论中药对子宫内膜感受态的影响体现了方药所具有的肾气样作用,是中医肾"精、气、血"的综合体现.     

MMP-26在子宫内膜瘤和子宫内膜癌中的表达的研究

基质金属蛋白酶家族在肿瘤细胞的浸润、发生和生长过程中起着非常重要的作用。本研究通过用免疫组化的方法对MMP-26在子宫内膜癌和子宫内膜肿瘤的整个月经周期中的分布与定位以及对MMP-26与子宫内膜瘤各亚型、分期和级别之间的关系进行了研究。研究发现，MMP-26在子宫内膜癌和子宫内膜瘤月经周期的不同阶段均有表达。而且，在绝经后，MMP-26在子宫内膜癌中的表达强于子宫内膜瘤中的表达，而不是在月经周期的分泌期。MMP一26在子宫内膜上皮细胞中的表达最强，其次是血管上皮细胞，子宫肌层的平滑肌细胞和子宫内膜基质细胞。并且随着肿瘤的浸润深度和根据FIGO划分的肿瘤级别的升高MMP-26的表达增强。所以，MMP-26在子宫内膜和子宫内膜癌中的分布与表达说明MMP-26在子宫内膜肿瘤的发生上起着非常重要的作用。     

Role of 3D sonohysterography in the investigation of uterine synechiae/asherman's syndrome: Pictorial assay

Several imaging methods have been applied for evaluation of suspected uterine synechiae; however, sonohysterography is yet recognised as a valid and accurate modality. Performing three‐dimensional (3D) imaging along with sonohysterography enables evaluation of the uterus in the coronal plane to detect and grade the adhesions that characterise this condition. Thus, 3D sonohysterography is a minimally invasive and cost‐effective tool for investigating suspected synechiae and is particularly useful when the transvaginal sonography findings are normal.     

Epithelial–mesenchymal transition in carcinomas of the female genital tract

Invasion is a defining feature of malignancy, but the mechanisms of invasion in many common cancers, including gynaecological malignancies, remain unclear. However, it has been proposed that malignant cells may usurp a normal embryological process, epithelial–mesenchymal transition (EMT), as a means of acquiring migratory capacity. The synergistic role of the tumour microenvironment in EMT induction has also been explored and helps to explain the spatially restricted distribution of EMT at the deep tumour margin (invasive front). Furthermore, tumour cells undergoing EMT may acquire cancer stem cell characteristics, and this may be relevant to the entire metastatic process and to tumour recurrence and treatment failure. Nevertheless, doubts persist regarding the role of EMT in malignant progression in vivo, partly because few studies have correlated molecular and histological alterations in clinical pathology specimens. In the current review we summarize the evidence for EMT in the common gynaecological epithelial malignancies, and discuss the morphological and immunohistochemical changes occurring at the invasive tumour front that may represent EMT‐like processes. The possibility that carcinosarcomas represent a variant type of EMT with ‘fixed’ mesenchymal differentiation is also considered. Diagnostic histopathologists are ideally placed to critically evaluate the role of EMT in gynaecological and other types of malignancy.     

育胞养膜颗粒联合芬吗通对肾阳虚薄型子宫内膜的影响

目的观察育胞养膜颗粒联合芬吗通对肾阳虚薄型子宫内膜的影响。方法选取2015年6月～2017年6月在我院中医科就诊的肾阳虚薄型子宫内膜不孕患者62例,随机分为研究组与对照组,各31例,研究组芬吗通阴道上药同时口服育胞养膜颗粒,对照组芬吗通阴道上药同时口服阿司匹林。治疗3个月,比较两组子宫内膜厚度、卵泡发育情况、妊娠率和不良反应发生率。结果与各自治疗前比较,治疗后两组子宫内膜厚度均增加,差异有统计学意义(P0.05),两组成熟卵泡平均直径均增加,研究组治疗前后差异显著(P0.05),对照组治疗前后无显著差异(P0.05);治疗后组间比较,研究组子宫内膜厚度、成熟卵泡平均直径均大于对照组(P0.05),研究组宫内妊娠率高于对照组(P0.05)。两组均未发生明显不良反应。结论育胞养膜颗粒联合芬吗通可有效改善子宫内膜厚度和卵泡发育情况,提高妊娠率,疗效优于芬吗通联合阿司匹林。     

Granulocyte colony stimulating factor treatment of resistant thin endometrium in women with frozen-thawed blastocyst transfer

The aim of the study was to assess the granulocyte-colony stimulating factor (G-CSF) effect on unresponsive thin (<7 mm) endometrium in women undergoing frozen-thawed embryo transfer at the blastocyst stage. A total of 62 women with thin unresponsive endometrium were included in the study, of which, 29 received a G-CSF infusion and 33 who opted out of the study served as controls. Patients in both groups had similar endometrial thickness at the time of the initial evaluation: 6.50 mm (5.50-6.80) in the G-CSF and 6.40 mm (5.50-7.0) in the control group. However, after the infusion endometrial thickness increased significantly in the G-CSF group in comparison with the controls (p=0.01), (Δ) 0.5 (0.02-1.2) (p=0.005). In the G-CSF group endometrium expanded to 7.90 mm (6.58-8.70) while in the control group to 6.90 mm (6.0-7.75). Five women in each group conceived. The clinical pregnancy rate was 5/29 (17.24%) in the G-CSF treated group and 5/33 (15.15%) in the control group (p>0.05). The live birth rate was 2/29 (6.89%) in the G-CSF group and 2/33 (6.06%) in the control group (p>0.05). We concluded that G-CSF infusion leads to an improvement in endometrium thickness but not to any improvement in the clinical pregnancy and live birth rates. Until more data is available G-CSF treatment should be considered to be of limited value in increasing pregnancy rate.
