Is cholic acid responsible for embryo-toxicity of the post-receptive uterine environment?

HPLC analysis of the embryo-toxic fraction of human uterinefluid, collected between the 22nd and 25th days of the menstrualcycle, revealed the presence of cholic acid at high concentrations.It is suggested that cholic acid could be responsible for theembryo-toxicity of the uterine environment, which follows thereceptive period for implantation.     

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。     

Insulin-like growth factor I promotes leiomyoma cell growth in vitro

Objective: Our purpose was to determine whether insulin-like growth factors I and II preferentially stimulate uterine leiomyoma cells versus myometrial cells in monolayer culture.Study design: Leiomyomas and normal myometrium were obtained at hysterectomy from five premenopausal women. Specimens were enzymatically digested for use in primary monolayer cell cultures. By use of serum-free media, insulin-like growth factor I or II was added in 1, 10, and 100 ng/ml concentrations to both cell types with the patient serving as her own control. Cell number, prolactin production, and proliferative index values were measured on day 15 of cell culture.Results: Significant increases in cell number were found in the leiomyoma cultures (p < 0.05) treated with 10 and 100 ng/ml insulin-like growth factors I but not with insulin-like growth factos II. Neither factor exerted a stimulatory effect on myometrial cells.Conclusion: Insulin-like growth factor sI preferentially stimulates leiomyoma cells in monolayer culture. These results suggest an autocrine-paracine role in vivo for this factor in conjuction with gonadal steroids in promoting leiomyoma growth.     

子宫颈癌手术前放疗28例临床分析

我院１９８９年至１９９４年共行子宫颈癌广泛切除术和盆腔淋巴结清扫术３９例，其中２８例行术前放射治疗，１９例临床诊断为Ⅱｂ，随着手术技术的提高和术前放射治疗的配合，子宫颈癌的手术适应症的选择，可以扩大至Ⅱｂ，不增加手术的并发症，并具有一定的优点。     

An analysis of fluid loss during transcervical resection of submucous myomas

Objective: To determine the contribution of several variables to fluid loss during transcervical resection of submucous myomas.Design: An observational study using multiple linear regression analyses.Setting: A university-affiliated training hospital and a university department of clinical epidemiology and biostatistics.Patient(s): Patients with submucous myomas.Intervention(s): Transcervical resection of submucous myomas and monitoring of fluid loss.Main Outcome Measure(s): Patient age, uterine enlargement, treatment with GnRH analogues or 8-ornithine-vasopressin, type of anesthesia, number of myomas, intramural extension of the myoma (type of myoma), and operating time were tested as variables.Result(s): Only intramural extension of the myoma and operating time were obviously related to fluid loss. For the other variables, such a relation was weak at best. The relation between fluid loss and operating time was not modified by any of the other variables.Conclusion(s): Because fluid loss is an important limiting factor in the transcervical resection of submucous myomas, special attention should be paid to reduction of the operating time and preoperative assessment of the intramural extension of the myoma to guide appropriate patient selection.     

分娩时子宫下段MMP-9及其组织抑制剂TIMP-1的变化

目的:探讨基质金属蛋白酶(MMP)及其组织抑制剂(TIMP)在分娩发动、宫颈成熟和扩张中的作用和机制.方法:采用ELISA方法测定子宫下段组织中MMP-9和TIMP-1的浓度.有宫缩剖宫产组56例,其中第一产程组44例,第二产程组12例.以无宫缩剖宫产组16例为对照组.结果:有宫缩剖宫产组子宫下段组织中MMP-9和TIMP-1的浓度分别明显高于无宫缩剖宫产组(P<0.05,P<0.05).第一产程组中随宫口开大,MMP-9和TIMP-1的浓度各组间无显著性差异.第二产程组MMP-9和TIMP-1的浓度分别明显高于第一产程组(P<0.01,P<0.05).结论:MMPs和TIMPs的动态变化是分娩发动、宫颈成熟和扩张过程中的重要中间环节.
