Objective To study the changes of six sex hormones corresponding to the follicle growth during the normal menstrual cycle of Chinese women.Methods Thirty Chinese women with regular menstrual period and average age of (28.8±3.2) years were selected for the study by Peking Union Medical College Hospital in September,2010.Growth of follicles was monitored by using transvaginal sonography.Six sex hormones,including follicle-stimulating hormone (FSH),luteinizing hormone (LH),estradiol (E2),progesterone (P),testosterone (T),and prolactin (PRL) were measured by chemoluminescence immunoassay every day during a menstrual cycle.Nonparametric statistical analysis was used.ResultsMenstrual cycle of all the patients was in the range of 25 to 39 d,with mean of (29.5 ± 3.1) d.Length of follicular phase and luteal phase was 15.3 and 14.4 d,respectively.Number of days from antral follicle to emergence of dominant follicle,and from the latter to ovulation,was 6.2 and 8.9 d,respectively.Average diameter of preovulatory follicle was 19.33 mm.Both FSH and LH reached peak on the day before ovulation.P started to increase before ovulation and remained at a high plateau from 6th to 9th day after ovulation.Both PRL and T reached peak after ovulation,near the end of a menstrual cycle.Conclusions A small rise of LH and P emerges just 1 to 2 d before ovulation,indicating the maturing of follicle.PRL and T shows cyclic changes as follicle grows.Therefore,PRL and T levels should be measured in the early follicle phases in the clinical practice so that leading the impact of menstrual cycle minimal.

Objective To evaluate the efficacy and safety of domestic human recombinant FSH (rhFSH) in women with anovulation of WHO groupⅡ. Methods A randomized, blind, parallel-controlled, non-inferiority and multicenter study was performed. A total of 534 admitted to 13 hospitals from May 2008 to August 2009. There were 531 women with ovulatory disorder was included in the statistical analysis, were randomly divided into test group (domestic rhFSH, n=352) and control group (imported rhFSH, n=179). Percentage of cycle with mature follicle, ovulation rate, clinical pregnancy rate, multiple pregnancy rate, ovarian hyperstimulation syndrome (OHSS) and adverse events were observed. Results No statistical significant differences (P>0.05) were observed between the two groups in terms of the efficiency on mature follicle [91.8%(323/352) versus 88.8%(159/179)], ovulation rate [91.3%(295/323) verus 90.6%(144/159)], clinical pregnancy rate [19.2%(62/323) verus 18.2%(29/159)], the number of the follicles0.05), and no other adverse events were observed in test group during treatment. Conclusion Ovarian stimulation with domestic rhFSH is effective, safe and economical in women with anovulation of WHO groupⅡ.

Objective To study the relationship between breast symptom, characteristic of ultrasound image and sex hormone level in women with different menstruation status.Methods 50 women with normal men-strual cycle, 129 women in menopause transition and 318 menopausal women were recruited.Breast ultrasound were performed.Breast section thickness, ductal width, breast structure and blood flow were measured.Serum estradiol( E2 ) and progesterone( P) level were measured by enzyme immunoassay on the day when ultrasound was performed.Onset and persistent days of breast pain were recorded.Results ①32(60.4%)women with normal menstrual cycle and 74(57.4%)women in menopause transition women experienced cyclic mastalgia.The aver-age serum E2 level and serum progesterone level were higher in women with cyclic breast pain than in women with-out breast pain.12.5%of menopausal women had breast pain.There was no significant difference of average ser-um E2 level between women with cyclic breast pain and women without breast pain②Breast section thickness was (14.4 ±4.3)mm,(13.0 ±3.7)mm and(10.6 ±3.2)mm, and ductal width was(0.62 ±0.18)mm,(0.88 ± 0.39)mm and(0.90 ±0.47)mm in normal menstrual group, menopause transition group and menopausal group, respectively.The difference had statistical significance.③26 women ( 49.1%) in normal menstrual group had breast structure changes, while 42 cases ( 32.6%) and 60 cases ( 18.9%) in menopause transition group and menopausal group had breast structure changes.Conclusions Most women in normal menstruation and meno-pause transition group experience mastalgia.About 1/3 breast structure change in women of normal menstruation are inversible.About 1/2 breast structure change in menopause transition and menopausal group are similar to those with normal menstruation.

Objective To study the efficacy and safety of estradiol and drospirenone tablets (Angeliq)in treatment of menopausal symptoms among postmenopausal Chinese healthy women.Methods Total 244 postmenopausal Chinese healthy women who had moderate to severe hot flushes were randomly assigned for 16 weeks in this randomized multi-center double-blind placebo-controlled study.During the trial.the follow-up visits were conducted at week 4,8,12,16 of treatment and 2 weeks after treatment respectively.Height,weight,vital signs,hot flushes,other relevant menopausal symptoms and vaginal bleeding were observed in each follow-up visit,while the clinical global impression scale Was assessed at 16 weeks as well.Results It showed that hot flushes were reduced significantly more in observation group than that in placebo group ( P＜0.01 ), although both treatments were effective. The absolute values of mean severity index of total hot flushes decreased by - 0. 6± 0. 5 in observation group and - 0. 4 ± 0. 4 in placebo group from baseline respectively, which reached significant difference ( P ＜ 0. 05 ). However, the absolute values of mean severity index of moderate to severe hot flushes decreased by - 0. 6± 0. 8 in observation group and -0. 3± 0.6 in placebo group from baseline respectively, which had no significant difference (P ＞ 0. 05 ).After 16 weeks treatment, it also showed that estradiol and drospirenone had significant better efficacy than placebo on moderate to severe sweating, vaginal dryness and clinical global impression scale (P ＜0. 01 ).During the trial, blood pressure in observation group was stable. The rate of vaginal bleeding in observation group was higher than that in the placebo group, especially during the week 4 to week 8 when 48. 9% (87/178) in observation group and 10. 7% (6/56) in placebo group of patients bled. Although the cumulative amenorrhea rate of observation group was lower than that of placebo group in each cycle (28 days), it increased gradually along with duration of the treatment. The commonest adverse event in observation group was breast tenderness which accounted for 12.0% (22/183 ). The level of serum potassium was in the normal range in observation group mostly. Meanwhile, the other adverse events rate was low. Serious adverse events reported in this trial were assessed as not study drug related or as unlikely study drug related. Conclusion Estradiol and drospirenone tablets which could effectively alleviate menopausal symptoms in postmeuopausal Chinese healthy women is a novel hormone replacement therapy regimen with high safety and efficacy.
Résumé
Objective To identify the potential neoplastic risk in gonadal development abnormality with Y chromosome.Methods Inquiries about the illness history were made.Lymphocyte chromosoreal karyotype of peripheral blood Was analyzed.Sex determining region Y gene and relative steroids and enzymes were detected.Gonadal site was examined through medical imaging.Conadal excision Was performed by laparotomy or laparoscopy.Pathological examinations were done on all of the specimens.Results Among 41 cases of androgen insensitive syndrome,spermatogenie cell neoplasm occurred in 1 patient,sertoli cell tumor in 2,and interstitial cell hyperplasia in 5.Among 14 cases of 17a.hydroxylase deficiency(XY)syndrome,one was sertoli eell tumor,and one Was sertoli cell hyperplasia.In 4 cases of XY pure gonadal dysgenesis.one was gonadoblastoma with dysgerminomm One of 16 cases of X0/XY gonadal dysgenesis Was spermatogenic cell neoplasm with agenda cell tumor.Four cases of testes degeneration were all with dysgenetic testes.All of the gonadoblastoma and germ-cell tumor were located in the pelvis.Tumors occurred mostly during 15 years of age to 32 years.Conclusions The gonads of XY pure gonadal dysgenesis has high risks of gonadoblastoma and germ-cell tumor.The older the onset age after puberty. the higher the malignancy risk is.Once diagnosed,bilateral gonads should be excised as soon as possible.
