①关于药物引起的卵巢抑制:1篇系统评价发现,使用卵巢抑制药治疗子宫内膜异位症与安慰剂或达那唑相比,妊娠率无明显差异.该评价还发现,卵巢抑制药引起的不良反应包括体重增加、潮热和骨质疏松症,达那唑可能引起剂量相关的体重增加和雄激素样作用. ②宫腔内人工授精+促性腺激素:1个RCT发现,宫腔内人工授精+促性腺激素治疗与不治疗相比,可明显提高活产率.第2个RCT发现,期待疗法与宫腔内人工授精+垂体降调节+促性腺激素治疗后的分娩率无明显差异.第3个RCT发现,宫腔内人工授精+促性腺激素治疗与单用宫腔内人工授精相比,仅明显提高妊娠率. ③体外受精:我们没有找到关于子宫内膜异位症引起不孕妇女接受受精体外治疗的RCT. ④手术治疗:两个比较腹腔镜手术与诊断性腹腔镜的RCT发现,在妊娠率和活产率方面结论不一.
ObjectiveTo systematically review the effectiveness and safety of laparoscopy with postoperative gonadotropin releasing hormone agonist (GnRH-a) versus laparoscopy alone for endometriosis. MethodsRandomized controlled trials (RCTs) on laparoscopy with postopertative GnRH-a versus laparoscopy alone in treatment of endometriosis were retrieved in the following databases:the Cochrane Library (Issue 3, 2013), PubMed, EMbase, WanFang Data, CNKI, and CBM from inception to February, 2013. According to the inclusion and exclusion criteria, the literature were screened, the data was extracted and the methodological quality of the included studies was also assessed by two reviewers independently. Then, meta-analysis was performed using RevMan 5.1.7 software. ResultsA total of 15 RCTs involving 1 761 patients were included. There were statistically significant differences between the laparoscopy with postoperative GnRH-a group and the laparoscopy alone group in the following 4 aspects:the symptom relief rate (RR=1.24, 95%CI 1.16 to 1.33, P < 0.000 01), the recurrence of lesion (RR=0.35, 95%CI 0.24 to 0.51, P < 0.000 01), the recurrence of pain (RR=0.70, 95%CI 0.53 to 0.92, P=0.01), and the pregnancy rate (RR=1.43, 95%CI 1.25 to 1.65, P < 0.000 01). ConclusionLaparoscopy postoperative GnRH-a for endometriosis can enhance the symptom relief rate, reduce the recurrence of lesion and the recurrence of pain, and increase the pregnancy rate. But because of the limitation of the quality of the included studies and publication bias, the above conclusion should be verified by conducting more high quality RCTs.
目的 探讨不同剂量和不同疗程米非司酮对大鼠子宫异位内膜基质金属蛋白酶-9（MMP-9）及其组织特异性抑制物-1（TIMP-1）表达的影响。 方法 65只子宫内膜异位症大鼠随机分为低剂量组、高剂量组、对照组。各个剂量组分别灌胃20、30、40 d后取异位子宫内膜组织用免疫组织化学法检测MMP-9及TIMP-1的表达，并计算MMP-9/TIMP-1比值。 结果 低剂量组和高剂量组均能使异位内膜MMP-9表达下降（P＜0.05）,TIMP-1表达升高（P＜0.05）,高剂量组的作用更加明显，与低剂量组差异有统计学意义（P＜0.05）；用药30 d低剂量组TIMP-1表达最高，与用药20 d和40 d相比差异有统计学意义（P＜0.05）,同样高剂量组用药30d TIMP-1的表达也最高，与用药20 d和用药40 d比较差异有统计学意义（P＜0.05）。与用药20、40 d比较差异有统计学意义（P＜0.05）。 结论 米非司酮能够降低大鼠异位子宫内膜的侵袭能力，高剂量米非司酮抑制效果更明显；用药30 d米非司酮对大鼠异位内膜的侵袭能力抑制最强，延长用药时间不能使异位内膜侵袭能力继续下降。

Endometriosis (EM) is a common benign gynecological disease with complex pathogenesis and lack of unified understanding. In recent years, the theory of stem/progenitor cells has gradually been recognized by scholars. The presence of stem/progenitor cells in the endometrium and researchers’ understanding of stem/progenitor cell specific markers has been further developed, which is of great significance for sorting stem/progenitor cells and further elucidating their roles in the pathogenesis of EM. At present, more endometrial stem cell signaling pathways have been studied including Wnt, Hedgehog, Notch, phosphatidylinositol-3-kinase/protein kinase B, Smad/connective tissue growth factor, CXCL12/CXCR4, etc. These signaling pathways can regulate stem cell involvement in the pathogenesis of EM. Exploring how signaling pathways to regulate stem cell involvement in the pathogenesis of EM can help elucidate the specific pathogenesis of EM and provide new directions for its treatment. This paper will summarize them.
ObjectiveTo evaluate the association between tumor necrosis factor alpha (TNF-α) gene -308G/A polymorphism and the risk of endometriosis (EM). MethodsDatabases including PubMed, EMbase, CBM, CNKI, VIP, and WanFang Data were searched to collect case-control studies about the association between TNF-α gene -308G/A polymorphism and the risk of EM from inception to October 2014. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. Then Meta-analysis was performed by using Stata 12.0 software. ResultsA total of seven case-control studies were included, which involved 687 patients and 877 controls. The results of meta-analysis showed that, AA genotype carriers presented 2.06-fold (OR=2.06, 95%CI 1.10 to 3.83, P=0.02) and 1.94-fold (OR=1.94, 95%CI 1.18 to 3.18, P<0.01) higher risk of EM than GG genotype carriers and AG+GG genotype carriers, respectively; but sensitivity analysis showed that the robustness of these results was unstable. No statistical significance was found in the allele model, co-dominant model, and dominant model (A vs. G: OR=1.37, 95%CI 0.87 to 2.17, P=0.18; AG vs. GG: OR=1.09, 95%CI 0.77 to 1.53, P=0.63; AA+AG vs. GG: OR=1.29, 95%CI 0.95 to 1.77, P=0.11). While excluding studies that controls were not in HWE, no significant association was observed in these five genetic models; and no significant association was found in the results of subgroup analysis by ethnicity. ConclusionThe AA genotype of TNF-α gene -308G/A polymorphism might contribute to the risk of EM, but the association between other genotypes and EM susceptibility is unclear. In addition, due to the limited quantity and quality of included studies, more high quality studies are needed to verify the above conclusion.
Objective To systematically evaluate the correlation between endometriosis (EM) in Chinese women and Xba I polymorphism in intron-1 of estrogen receptor α (ER-α) gene. Methods Such databases as PubMed, MEDLINE, The Cochrane Library (Issue 3, 2012), VIP, CBM, WanFang Data and CNKI were searched to collect case-control studies about the correlation between EM and Xba I polymorphism in intron-1 of ER-α gene. The retrieval time was from 1980 to 2012. Two reviewers independently screened the literature according to the inclusion and exclusion criteria, extracted the data and assessed the quality, and then the meta-analysis was conducted by using RevMan 5.0 and Stata 12.0 software. Results A total of 7 studies involving 676 EM patients and 688 healthy volunteers were included. The results of meta-analyses showed that Chinese women with X/X genotype had similar risk of EM compared to those with x/x genotype (OR=0.95, 95%CI 0.58 to 1.54, P=0.82) or X/x genotype (OR=0.73, 95%CI 0.44 to 1.20, P=0.22). The allele X also showed similar risk of EM compared to the allele x (OR=1.11, 95%CI 0.93 to 1.33, P=0.25). Conclusion At present, it has not yet been found that the incidence of EM in Chinese women is related to the Xba I polymorphism in intron-1 of ER-α gene as well as the allele X. For the quantity and quality limitation of the included studies, this conclusion has to be proved by more studies.
Pulmonary endometriosis (PEM) is a rare disease with diverse clinical manifestations, most commonly presenting as hemoptysis, while patients presenting solely with pulmonary nodules are less common. Here, we report three female patients (aged 32, 19, and 46 years, respectively). One patient sought medical attention due to hemoptysis during menstruation, while the other two had no obvious symptoms and were found to have pulmonary nodules during routine physical examinations. Two patients had a history of cesarean section, and one had a history of miscarriage. Pathologically, one patient of PEM showed extensive hemorrhage in the alveolar spaces, with fragmented endometrial glandular epithelium observed within the hemorrhagic foci. The other two patients exhibited proliferative endometrial glands and stroma, surrounded by old hemorrhage. Immunohistochemistry revealed that the endometrial glands and stroma in all three patients were positive for estrogen receptor, progesterone receptor, and vimentin, with CD10 positivity in the endometrial stroma. All three patients were definitively diagnosed as PEM by pathology and underwent thoracoscopic pulmonary wedge resection. Follow-up periods were 18, 31, and 49 months, respectively, with no recurrence observed in any of the patients.
【摘要】 目的 观察腹腔镜手术联合孕三烯酮治疗子宫内膜异位症合并不孕的疗效及不同评分系统对妊娠结局的预测价值。 方法 回顾性分析2004年1月-2006年12月收治的97例子宫内膜异位症合并不孕患者的临床病理资料，统计其术后妊娠率及活产率。 结果 术后1年内与1~2年的妊娠率与活产率比较，差异均无统计学意义（Pgt;0.05）。根据美国生育协会1985年修订的子宫内膜异位症分期标准（r-AFS）进行分期，各期患者术后妊娠率差异无统计学意义（Pgt;0.05）；但随着分期升高，活产率逐渐下降（Plt;0.05）。子宫内膜异位症生育指数（EFI）评分越高，其妊娠率和活产率也越高（Plt;0.05）。 结论 子宫内膜异位症患者腹腔镜手术后联用孕三烯酮可能会提高远期妊娠率。r-AFS分期对妊娠结局的预测有一定局限性，而EFI具有较好的预测性。【Abstract】 Objective To evaluate the therapeutic effectiveness of laparoscopic surgery combined with gestrinone treatment in the infertile women with endometriosis (EM), and the value of different score systems to predict gestational outcome. Methods We retrospectively analyzed the clinical data of 97 infertile women with EM who were treated in our hospital from January 2004 to December 2006, and collected their pregnancy rate (PR) and live birth rate (LBR) after operation. Results There was no significant difference of PR and LBR within the 1st year and between the 1st and the 2nd year (Pgt;0.05). There was no significant difference of PR among women of various stages of EM based on the 1985 edition of risk stratification for patients with EM put forward by American Fertility Society (r-AFS) (Pgt;0.05), but the LBR decreased with the raising of the stages (Plt;0.05). The endometriosis fertility index (EFI) was positively correlated with PR and LBR (Plt;0.05). Conclusion Laparoscopic surgery combined with gestrinone may increase the long-term pregnancy rate of women with EM. R-AFS classification is limited in predicting the gestational outcome of women with EM, while EFI achieves a better result.
