子宫内膜功能亢进性疾病的“异病同治”诊治研究思路＊

笔者根据现代临床子宫内膜的病理演变过程结合中医“异病同治”理念，提出“子宫内膜功能亢进性疾病”概念，涵盖5种常见的子宫内膜疾病：无排卵性异常子宫出血（Abnormal Uterine Bleeding Ovulatory dysfunction，AUB-O），子宫内膜息肉（Endometrial Polyp，EP），子宫内膜异位症（Endometriosis，EMs），子宫腺肌病（Adenomyosis，AM），子宫内膜癌（Endometrial Carcinoma，EC）。基于文献的汇总，分析得到此类疾病的子宫内膜病理演变与中医病因病机的关联性，为寻找关键通路、创新性治疗此类疾病提供了重要的参考方向，对深化中医妇科学常见疾病的共性病因病机提供了理论依据和探索思路。     

二补助育汤对胚胎着床障碍小鼠子宫血管生成相关因子表达的影响

目的：探讨二补助育汤对胚胎着床障碍模型小鼠子宫内膜形态及血管生成素-1（Ang-1）mRNA、血管内皮生长因子（VEGF）mRNA的表达和定位的影响。方法：24只ICR雌性小鼠随机分为空白组、模型组、戊酸雌二醇组、二补助育汤组，每组6只，用米非司酮建立胚胎着床障碍动物模型，各组给予相应药物灌胃，妊娠第5天处死小鼠后，检测各组妊娠率、平均着床位点数、子宫内膜Ang-1和VEGF mRNA表达量及其蛋白定位。结果：模型组小鼠平均胚胎着床位点数、Ang-1 mRNA、VEGF mRNA表达量明显低于空白组（均P<0.05）；与模型组比较，二补助育汤组平均胚胎着床位点数、Ang-1 mRNA、VEGF mRNA表达量显著提高（均P<0.05）。结论：二补助育汤可提高子宫内膜Ang-1和VEGF蛋白表达量，促进子宫内膜血管生成，从而提高子宫内膜容受性。     

甲状腺功能减退与子宫内膜癌的相关性分析

 目的 探讨甲状腺功能减退与子宫内膜癌（EC）的关系及EC患者癌组织分化程度和雌激素受体（ER）、孕激素受体（PR）的表达与甲状腺功能之间的关系。方法 选取2015年1月—2018年7月我院收治的EC患者113例，同时随机选取年龄与EC组相匹配的此段时间内我院健康体检的妇女156例作为对照组，检测血清促甲状腺激素（TSH）、甲状腺激素（FT4）。比较两组间甲状腺功能减退的患病率，并利用免疫组织化学法测定EC患者手术切除标本的癌组织中ER、PR的表达，分析EC患者癌组织分化程度及癌组织中ER、PR的表达与甲状腺功能之间的相关性。结果 EC组甲状腺功能减退的患病率较对照组高（P<0.000）。低分化EC患者的TSH高于中分化EC患者（P=0.025）。EC手术切除标本的癌组织中ER、PR阳性与阴性患者的TSH、FT4差异无统计学意义（P>0.05）。结论 甲状腺功能减退与EC具有相关性。     

Suppression of PRDX4 inhibits cell proliferation and invasion of ectopic endometrial stromal cells in endometriosis

Abstract

Oxidative stress (OS) has been proposed to play a role in the development of EMs. Peroxiredoxins are a family of antioxidant proteins that exhibit peroxidase activity in a thioredoxin-dependent manner, protecting cells against OS. The Western blotting results showed that the relative expression of PRDX4 was significantly increased in ectopic endometria compared with the normal endometria of EMs-free (p?<?.05). The H₂O₂ concentration was also significantly higher in the ectopic endometrium. PRDX4 siRNA was transfected into primary ectopic endometrial stromal cells (EESCs). The viability of the transfected EESCs was measured by CCK-8 assay, and the results showed significantly decreased cell viability. Furthermore, the apoptosis rate and ROS generation in flow cytometry assays were significantly increased after the knockdown of PRDX4 expression (p?<?.05). Scratch assays and transwell assays revealed that decreased expression of PRDX4 mediated by siRNA inhibited EESC migration and invasion. In conclusion, these findings indicate the potential role of PRDX4 in the development of EMs and PRDX4 as a possible therapeutic target for EMs treatment.     

Long-term results in the treatment of menorrhagia and hypermenorrhea with a thermal balloon endometrial ablation technique.

BACKGROUND AND OBJECTIVES: Evaluation of long-term results using a thermal balloon endometrial ablation technique to treat menorrhagia and hypermenorrhea, considered dysfunctional uterine bleedings. METHODS: A single-arm, prospective study with long-term follow-up of 48 months at the department of obstetrics and gynecology, University of Kiel, Germany. Following hysteroscopic evaluation of the uterine cavity and fractionated curettage, the Cavaterm endometrial thermal ablation technique was performed on 70 patients over the age of 40 with menorrhagia and hypermenorrhea in whom medical treatment had previously failed. The study included a group of 10 patients with adenomyosis and uterine fibroids. RESULTS: In 65 patients, a complete 48-month follow-up evaluation was possible: 58% of patients reported amenorrhea and 33% hypomenorrhea. Nine percent of patients remained eumenorrheic. Fifty percent of the small group with failed indications for the procedure had to undergo a hysterectomy. CONCLUSIONS: The Cavaterm thermal coagulation system in the earlier mode of application (15 minutes at a temperature of 70 degrees C and a pressure of 200 mm Hg) is a safe and highly effective method of endometrial ablation resulting in a minimal amount of posttreatment menstrual bleeding.     

Successful pregnancy after recurrent hysteroscopic polypectomy

This case demonstrates that hysteroscopic polypectomy can enhance fertility. A 35-year-old woman was being evaluated for assisted conception. She was referred from an in vitro fertilisation clinic for polypectomy, which she had undergone on two occasions. She conceived spontaneously, had an uneventful antenatal period, and delivered a healthy baby at 39 weeks' gestation.     

子宫内膜萎缩疗法治疗青春期功血362例临床研究

目的：探讨子宫内膜萎缩疗法治疗青春期功血（DUB）的止血效果。方法：将362例平均分为观察组（采用炔诺酮、戊酸雌二醇联合疗法止血）和对照组（单用炔诺酮子宫内膜萎缩疗法止血），两组各181例，比较两组的止血效果。结果：观察组和对照组止血有效率分别为96．13％（174／181）和92．27％（167／181），两组比较差异无统计学意义（踟105）；观察组和对照组控制出血时间分别为（28．69±14．87）h和（29．72±15．34）h，两组比较差异无统计学意义（踟．05）。观察组和对照组的完全止血时间分别为（32．80±19．10）h和（47．30±18．60）h，两组比较差异有统计学意义（／9〈0．05）。观察组和对照组的住院天数平均为（6．10±2．80）d和（6．9±2．60）d，观察组住院时间短于对照组（P〈0．01）。结论：炔诺酮止血疗法和炔诺酮、戊酸雌二醇联合疗法治疗青春期功血效果均较好，但炔诺酮、戊酸雌二醇联合疗法治疗效果更佳。     

Endometrial carcinoma: Does the addition of intracavitary vault caesium to external beam therapy postoperatively result in improved control or increased morbidity?

A retrospective analysis of treatment for endometrial carcinoma is reported here. From 1987 to 1989, 138 patients were referred to the oncology department following total abdominal hysterectomy and bilateral salpingo-oophorectomy for endometrial cancer. Forty-seven patients were not prescribed postoperative radiotherapy; 31 had Stage I well differentiated adenocarcinoma with minimal myometrial invasion, while the remaining 16 patients were considered unfit for postoperative radiotherapy. There were no instances of local relapse amongst the 31 patients with minimal myometrial invasion.The remaining 91 patients all received external beam irradiation to the pelvis and, according to the preference of the individual therapist, 51 were prescribed additional intracavitary vault caesium-137. Patients receiving postoperative radiotherapy were analysed according to whether or not they received additional intracavitary vault caesium. The two groups were also analysed for incidence of vaginal vault recurrence and treatment related morbidity.In the group receiving additional intracavitary treatment more patients had Stage II or III disease (P<0.05), and had greater depth of myometrial invasion (P<0.05). Vaginal vault recurrence was not observed in patients receiving intracavitary therapy in addition to external beam therapy. Four patients (10%) receiving external beam therapy alone developed vaginal vault recurrence.The incidence of Kottmeier-Perez grade 2 or 3 bowel toxicity following treatment was significantly higher in those patients receiving combined treatment (18% vs. 2.5%; P<0.03). There was also a higher incidence of vaginal stenosis in the group receiving both external beam and intracavitary therapy (21% vs. 3%; P<0.05). There was only one instance of grade 2 bladder toxicity in the external beam and intracavitary treatment group and none in the external beam therapy alone group.In conclusion, postoperative radiotherapy for Stages I-III endometrial carcinoma was carried out in a non-randomized manner by two regimens; either external beam therapy alone or external beam therapy with additional intracavitary vaginal caesium. The combined therapy gave significantly better local control but resulted in significantly more late bowel and vaginal morbidity.     

子宫内膜增生性病变与子宫内膜癌的超声诊断价值

目的:探讨子宫内膜增生性病变与子宫内膜癌的超声鉴别诊断及内膜癌肌浸程度的估价.方法:采用术前B超、术后大体标本观察测量,对123例子宫内膜病变患者的声像图资料进行分析并与手术后病理结果对照.结果:①子宫内膜病变者子宫三径之和平均值均大于正常值;②58.6%的子宫内膜增生过长病变患者内膜形态以条形、梭形和正常形态回声;35%的Ⅱ期以上子宫内膜癌患者内膜回声以积液为主兼有其它图像类型;③大于50岁患者不同病理类型病变的子宫内膜平均厚度均超过其正常内膜厚度值,但无明显的规律性.小于50岁的患者内膜增厚主要以子宫内膜增生过长病变为主占48%;④通过超声测量子宫内膜厚度判断子宫内膜癌浅肌层和深肌层浸润符合率均为71.4%.结论:超声检查对判断子宫内膜病变病理类型有一定帮助,内膜厚度、内膜形态、回声特点、及内膜与肌层间的关系等,仅提示病变存在的可能性,要鉴别病变的良恶性、肌层浸润深度,须根据上述回声特点进行综合分析.
