卵巢恶性肿瘤的雌孕激素受体研究

用葡聚糖－活性碳吸附法（ＤＣＣ法）对８７例卵巢恶性肿瘤的雌激素受体（ＥＲ）及孕激素受体（ＰＲ）进行了测定。ＥＲ、ＰＲ的阳性率分别为５０．６％和５８．６％。在不同组织类型中，宫内膜样癌的ＥＲ与ＰＲ高于其它癌。ＰＲ与临床分期呈负相关。多因素分析显示ＥＲ、ＰＲ均阳性者预后好。ＥＲ与ＰＲ的测定有助于了解病人预后，对卵巢癌的内分泌治疗有一定指导作用。     

IVF周期中性激素水平的改变与临床妊娠率的相关性

目的探讨超排卵周期中血清雌、孕激素水平的变化及其与临床妊娠率的关系。方法56例不孕患者经普通IVF-ET(包括ICSI)过程,于注射FSH或HMG(启动日)、启动后4～7天、注射HCG日测定血清雌、孕激素、FSH、LH水平,于停经后6～8周行腹部B超检查示宫腔内孕囊存在并伴HCG上升则确认为临床妊娠。将临床妊娠组(23例)及非临床妊娠组(33例)的上述3日雌、孕激素、FSH、LH水平作一回顾性的分析对比。结果雌、孕激素、FSH水平随周期天数增加而增加,LH水平随周期天数增加而减少;临床妊娠组比非临床妊娠组雌、孕激素、FSH、LH水平略低,以HCG日较为明显,但两组雌、孕激素、FSH、LH水平间没有明显差异(P>0.05)。结论在IVF周期中, 临床妊娠率可能与多种因素有关,雌,孕激素的水平对胚胎着床的影响将有待我们提高样本量进一步探讨。     

Autoimmune progesterone dermatitis: absence of contact sensitivity to glucocorticoids, oestrogen and 17-α-OH-progesterone

Autoimmune progesterone dermatitis is a rare condition, characterized by recurrent premenstrual exacerbations of a dermatosis, in which sensitivity to progesterone can be demonstrated. The sensitizing mechanism is unknown. The aim of this study was to test the hypothesis that cross-sensitivity between steroid groups could induce allergy to endogenous progesterone in these patients. 5 patients with autoimmune progesterone dermatitis and 1 with oestrogen-sensitive dermatitis have been patch tested with a corticosteroid series, conjugated oestrogen 1% in petrolatum (pet.), and 17-α-OH-progesterone 2% pet. There were no immediate or delayed reactions at 2 and 4 days to any steroid group. We have therefore been unable to demonstrate steroid cross-sensitivity, or a use for 17-α-OH-progesterone in the investigation of oestrogen - and progesterone-sensitive dermatoses.     

Prospective randomized study of D-Trp6-LHRH versus buserelin in long desensitization protocols for medically assisted conception cycles

In a prospective, controlled, randomized study where two differentagonists were used, we compared three different long desensitizationprotocols for induction of multiple follicular growth in medicallyassisted conception cycles. In protocol A, 30 patients wereinjected with buserelin twice a day for 15 days prior to ovarianstimulation until human chorionic gonadotrophin (HCG) administration.In protocol B, 30 patients were injected with a single doseof long acting Triptorelin (3.75mg) 15 days before the ovarianstimulation onset. In protocol C, 30 patients were injectedwith the long acting Triptorelin 4 weeks before ovarian stimulationfollowed by daily administration of 0.1 mg of the same agonistuntil HCG injection. There was no difference in the ovarianresponse to exogenous gonadotrophin stimulation, except forthe presence of premature luteinization in two patients in groupB. A significantly higher number of mature oocytes was collectedfrom patients with protocol A; however, the fertilization andcleavage rate demonstrated no significant difference among thethree groups of patients. The ongoing pregnancy rate and theimplanation rate per treatment cycle were very similar in thethree study groups. When the convenience, cost and side-effectsfor the patient are being considered, protocol B should be selectedas the first choice when the agonist is utilized for the purposeof inducing pituitary desensitization before and during ovarianstimulation.     

Effect of exogenous progesterone administration on the morphology of normally developing endometrium in the pre-implantation period

The effects on endometrial morphology of a single, intramuscular dose of 100 mg of progesterone administered in the early luteal phase, between days LH + 1 and LH + 6, were studied in a group (n = 8) of normal, fertile subjects by morphometric techniques and transmission electron microscopy. While the dose of progesterone administered consistently resulted in an increase of salivary progesterone concentration to above the upper limit of the reference range, no significant effect on endometrial development was observed; in particular, endometrial development was not advanced.     

Aggressive angiomyxoma of the female pelvis and perineum: a case series

Aggressive angiomyxoma (AA) was first described in 1983, and fewer than 150 cases have been reported in the world medical literature. These tumors are benign, locally infiltrative mesenchymal neoplasms with a predilection for the female pelvis and perineum and a tendency to recur. The size of AAs at presentation varies considerably; however, these tumors often achieve large dimensions before becoming clinically symptomatic. Surgical excision remains the mainstay of treatment, but whether clear, tumor-free surgical margins are necessary is controversial. We report a cohort of six patients treated surgically during the past 20 years for primary or recurrent AA. Treatment, surgical margin status, estrogen and progesterone receptor status, and outcomes are reviewed.     

孕激素联合化疗治疗卵巢上皮性癌

目的 分析孕激素联合以铂类为主的常规化疗对卵巢上皮性癌1～4期患者的临床疗效。方法 以已行瘤体减灭术的卵巢上皮性癌患者1～4期为研究对象，分为单纯化疗组、己酸孕酮组和普维拉组。随访、统计各组各期患者的生存率及复发率、血清激素水平、骨密度变化以及化疗副反应。结果 孕激素联合以铂类为主的化疗对早期卵巢上皮性癌的预后无明显影响，但对晚期(3期)卵巢上皮性癌的术后近期以及远期(2～5年)生存率及复发率均有改善趋势。单纯化疗组、己酸孕酮组、普维拉组3期患者术后3年生存率分别为34．8％、66．2％、73．9％，复发率分别为72．2％、47．3％、40．6％；单纯化疗组、己酸孕酮组术后5年生存率分别为17．4％、48．4％，复发率分别为81．5％、62．4％。孕激素的使用不影响患者血清激素水平，也不增加化疗的毒、副作用。联合孕激素治疗的患者术后骨密度下降较一般绝经后妇女慢。结论 孕激素联合以铂类为主的常规化疗可改善晚期卵巢上皮性癌的预后，并且不增加化疗的毒副作用，可改善患者的骨量丢失。     

克罗米酚对血清雌激素和孕激素水平的影响

目的探讨克罗米酚(CC)在诱发排卵过程中对雌、孕激素水平的影响。方法采用放射免疫法,测定16例不明原因不孕妇女在自然周期和用药周期的排卵前1天和排卵后10天血清雌二醇(E2)和孕酮(P)浓度。结果排卵前1天和排卵后10天,用药周期的E2、P浓度均高于自然周期(P<0.05)。结论克罗米酚在诱发排卵过程中可导致内源激素平衡紊乱。
