Effect of peritoneal fluid from patients with mild and severe endometriosis on endometrial stromal cell proliferation

The aim of this study was to evaluate and compare the mitogenic effect of peritoneal fluid (PF) from women with mild and severe endometriosis on the endometrial stromal cell proliferation. Increasing concentrations of PF from women with and without mild or severe endometriosis were added to primary endometrial stromal cell cultures and³H-thymidine incorporation was used to assess DNA synthesis in these cultures. PF from women with mild endometriosis induced a statistically significant dose-dependent increase in stromal cell thymidine uptake ranged from 5.8 to 14.5 fold, whereas PF from women with severe endometriosis produced an average 51% inhibition of stromal cell proliferation of compared with cells exposed to non-endometriosis PF or exposed to nutrient medium supplemented with 2.5% calf serum alone. PF samples from patients with stage I endometriosis induced a statistically dose-dependent increase in stromal cell proliferation, whereas PF from patients with stage IV endometriosis caused a significant inhibition.     

182例子宫内膜癌的疗效分析

目的：探讨子宫内膜癌的疗效从其预后因素。方法;收集1979年4月至1991年4月随访资料完整的182例子宫内膜癌。全组病人均经手术及术前放疗，部分病人术后放疗。经统计学X2检验分析预后。结果：总5年生存率80.2％，Ⅰ期91.9％，Ⅱ期81％，Ⅲ期56％，Ⅳ期0，临床分期、病理类型、组织学分级、宫体肌层浸润盆腔淋巴结转移是影响预后的重要因素、结论;术前分段诊刮至关重要、放宽1期病例下术指征是提高Ⅰ期盆腔淋巴结转移病例存活率的关键，术前术后放疗是防止复发提高存活率的有效措施。     

认知行为干预对子宫内膜癌手术患者术后病耻感及自我效能的影响

目的 探讨认知行为干预对子宫内膜癌手术患者术后病耻感及自我效能的影响.方法 选取2017年1月—2019年12月医院收治的子宫内膜癌手术患者80例为研究对象,按照组间基本特征具有可比性的原则分为对照组和观察组,各40例.对照组予以常规护理干预,观察组在对照组基础上给予认知行为干预,比较两组患者干预8周后病耻感及自我效能...     

单纯腹腔细胞学阳性子宫内膜癌Ⅲ a期患者的预后

目的　研究不同子宫内膜癌Ⅲa期患者的预后 ,为临床治疗提供依据。方法　对 1988～ 2 0 0 1年在我院收治的子宫内膜癌Ⅰ期、Ⅲ期患者共 191例进行回顾性分析。患者共分为四组 :第一组为Ⅰ期患者 ,共134例 ;第二组为单纯腹腔细胞学阳性的子宫内膜癌Ⅲa期患者 ,共 2 3例 ;第三组为伴有浆膜浸润或附件转移的子宫内膜癌Ⅲa期患者 ,共 16例 ;第四组为子宫内膜癌Ⅲb期 Ⅲc期患者 ,共 18例。采用Kaplan -Meier法对四组的平均生存时间进行计算 ,并进行比较。结果　①第一组与第二组的平均生存时间差异无显著性 ,P >0 0 5 ;②第二组与第三组的平均生存时间差异有明显统计学意义 ,P <0 0 1;③第三组与第四组的平均生存时间差异无显著性 ,P >0 0 5。结论　尽管腹腔细胞学阳性、浆膜浸润及附件转移均被定为子宫内膜癌Ⅲa期 ,但单纯腹腔细胞学阳性的患者其预后明显好于伴有浆膜层浸润或附件转移者。对她们应采取不同的后续治疗     

子宫内膜癌PTEN蛋白表达及其临床意义

目的 :探讨抑癌基因第 10染色体同源丢失性磷酸酶 -张力蛋白基因 (PTEN)蛋白表达与子宫内膜癌的发生、发展及复发的关系。方法 :采用免疫组织化学S P法检测PTEN蛋白在 5 0例子宫内膜癌、12例不典型增生子宫内膜及 10例正常子宫内膜组织的表达。结果 :5 0例子宫内膜癌中PTEN蛋白表达率为 5 6 0 0 % ,明显低于正常子宫内膜以及不典型增生子宫内膜中的表达 (10 0 0 0 %、91 0 0 % ) (P <0 0 5 )。PTEN蛋白在无肌层浸润或肌层浸润≤ 1/ 2的子宫内膜癌中阳性表达率为 76 0 0 % ,肌层浸润 >1/ 2或有淋巴结转移者为 36 0 0 % ,与肌层浸润程度显著相关 (P <0 0 5 ) ,且Ia Ib期与Ic期相比也有统计学差异 ;但与子宫内膜癌的组织学分级、有无复发无关 (P >0 0 5 )。结论 :抑癌基因PTEN蛋白表达缺失在子宫内膜癌的发生、发展、浸润及复发过程中有一定作用。     

CA125与子宫内膜抗体测定用于诊断子宫内膜异位症

测定了４２例妇女血清和腹腔液ＣＡ＿（１２５）及子宫内膜抗体（ＥＭＡｂ）水平，其中经腹腔镜诊断为子宫内膜异位症者２８例（观察组），无子宫内膜异位症者１４例（对照组）。结果表明：观察组血清ＥＭＡｂ的吸光度为０．４４±０．１３，明显高于对照组的０．３４±０．０７，但两组间血清ＣＡ＿（１２５）差异无显著性；两含用于诊断的敏感性分别为７１．４３％和８２．１４％，特异性为５７．２１％和５７．１４％。两组腹腔液中ＥＭＡｂ差异无显著性；两组腹腔液ＣＡ＿（１２５）和ＥＭＡｂ水平均明显高于血清。     

Heparanase expression increases throughout the endometrial hyperplasia-cancer sequence.

OBJECTIVE: To assess the expression of heparanase in the different stages leading to endometrial cancer. METHODS: The 38 examined specimens included adenocarcinoma, hyperplasia, and normal endometrium specimens. Heparanase, estrogen, and progesterone receptor expressions were analyzed immunohistochemically and the intensity was scored. RESULTS: Secretory normal endometrium and simple hyperplasia specimens expressed the lowest mean values of expression (1.00 and 0.63, respectively); the complex hyperplasia specimens and G2 endometrioid adenocarcinoma showed the highest values of expression (2.33 and 2.71, respectively). A linear trend (P=0.005) of heparanase expression was observed when comparing the normal endometrium and simple hyperplasia group with the complex hyperplasia+G1 carcinoma group and the G2+G3 carcinoma group. Evaluation of atrophic and inactive endometrium compared with papillary serous carcinomas yielded no significant differences. We found no significant correlation between heparanase expression and estrogen receptor or progesterone receptor expression. CONCLUSION: Heparanase expression was tightly regulated in endometrial tumorigenesis.
