RESUMEN
BACKGROUND: The effect of ovarian hyperstimulation syndrome (OHSS) on pregnancy outcomes of in vitro fertilization (IVF) patients is still ambiguous. This study aimed to analyze pregnancy outcomes of IVF with or without OHSS in Chinese patients. METHODS: A retrospective cohort study was undertaken to compare pregnancy outcomes between 190 women with OHSS and 197 women without OHSS. We examined the rates of clinical pregnancy, multiple pregnancies, miscarriage, live birth, preterm delivery, preterm birth before 34 weeks' gestation, cesarean delivery, low birth weight (LBW), and small-for-gestational age (SGA) between the two groups. Odds ratios (OR s) and 95% confidence intervals (CI s) of measure of clinical pregnancy were also analyzed. RESULTS: The clinical pregnancy rate of OHSS patients was significantly higher than that of non-OHSS patients (91.8% vs. 43.5%, P < 0.001). After controlling for drug protocol and causes of infertility, the adjusted OR s of moderate OHSS and severe/critical OHSS for clinical pregnancy were 4.65 (95% CI, 1.86-11.61) and 5.83 (95% CI, 3.45-9.86), respectively. There were no significant differences in rates of multiple pregnancy (4.0% vs. 3.7%) and miscarriage (16.1% vs. 17.5%) between the two groups. With regard to ongoing clinical pregnancy, we also found no significant differences in the rates of live birth (82.1% vs. 78.8%), preterm delivery (20.9% vs. 17.5%), preterm birth before 34 weeks' gestation (8.6% vs. 7.9%), cesarean delivery (84.9% vs. 66.3%), LBW (30.2% vs. 23.5%), and SGA (21.9% vs. 17.6%) between the two groups. CONCLUSION: OHSS, which occurs in the luteal phase or early pregnancy in IVF patients and represents abnormal transient hemodynamics, does not exert any obviously adverse effect on the subsequent pregnancy.

BACKGROUND: Thin endometrium is associated with poor reproductive outcomes; estrogen treatment can increase endometrial thickness (EMT). The aim of this retrospective cohort study was to investigate the factors influencing the effectiveness of estrogen treatment and reproductive outcomes after the treatment in patients with thin endometrium. METHODS: Relevant clinical data of 101 patients with thin endometrium who had undergone estrogen treatment were collected. Possible factors influencing the effectiveness of treatment were analyzed retrospectively by logistic regression analysis. Eighty-seven infertile women without thin endometrium who had undergone assisted reproduction served as controls. The cases and controls were matched for age, assisted reproduction method, and number of embryos transferred. Reproductive outcomes of study and control groups were compared using Student's t-test and the Chi-square test. RESULTS: At the end of estrogen treatment, EMT was ≥8 mm in 93/101 patients (92.1%). Effectiveness of treatment was significantly associated with maximal pretreatment EMT (P = 0.017) and treatment duration (P = 0.004). The outcomes of assisted reproduction were similar in patients whose treatment was successful in increasing EMT to ≥8 mm and the control group. The rate of clinical pregnancy in patients was associated with the number of good-quality embryos transferred in both fresh (P = 0.005) and frozen-thawed (P = 0.000) embryo transfer cycles. CONCLUSIONS: Thinner EMT before estrogen treatment requires longer treatment duration and predicts poorer treatment outcomes. The effectiveness of treatment depends on the duration of estrogen administration. Assisted reproductive outcomes of patients whose treatment is successful (i.e., achieves an EMT ≥8 mm) are similar to those of controls. The quality of embryos transferred is an important predictor of assisted reproductive outcomes in patients treated successfully with exogenous estrogen.

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 into estradiol and drospirenone (observation group, n = 183) or placebo group (n = 61) by the ratio of 3:1 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 postmenopausal Chinese healthy women is a novel hormone replacement therapy regimen with high safety and efficacy.

OBJECTIVE: To identify the potential neoplastic risk in gonadal development abnormality with Y chromosome. METHODS: Inquiries about the illness history were made. Lymphocyte chromosomal 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. Gonadal excision was performed by laparotomy or laparoscopy. Pathological examinations were done on all of the specimens. RESULTS: Among 41 cases of androgen insensitive syndrome, spermatogenic cell neoplasm occurred in 1 patient, sertoli cell tumor in 2, and interstitial cell hyperplasia in 5. Among 14 cases of 17 alpha-hydroxylase deficiency (XY) syndrome, one was sertoli cell tumor, and one was sertoli cell hyperplasia. In 4 cases of XY pure gonadal dysgenesis, one was gonadoblastoma with dysgerminoma. One of 16 cases of XO/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.

OBJECTIVE: To investigate the effects of long-term hormone replacement therapy (HRT) on the breasts of postmenopausal women using mammary ultrasonography. METHODS: An open randomized clinical study was designed. The percutaneous estradiol gel was used in a cyclic regimen combined with micronized progesterone (MP) or medroxyprogesterone acetate (MPA). Sixty healthy women (natural menopause for 1 to 5 years) were recruited and divided into four groups according to the dosage of estrogen and two kinds of progestin. All were given for 25 days per month. Mammary ultrasonography was used to observe breast glandular section thickness, breast duct width, the morphology of lobular unit and the blood flow of color Doppler imaging at baseline and every year from the second to seventh year of HRT. The serum estradiol was also measured from the 15th to 25th day of the cycle. Breast pain was recorded by the subjects. RESULTS: (1) The breast glandular section thickness after HRT was larger than that of before HRT. The breast glandular section thickness became larger gradually over time while the breast duct width became smaller over time. The breast duct width of the fifth year of HRT was significantly different from that of the sixth year (P < 0.05). (2) Twenty-two persons had new breast structure changes after HRT, and the accumulated incidence was 41.5%. New solid lesions formation occurred in five subjects (8.3%) and new cyst formation occurred in one subject (1.7%). After the second year of HRT, the serum estradiol level of the subjects with breast structure changes was higher than that of without breast structure changes and in the sixth year of HRT, and the difference was significant (P < 0.05). After the second year of HRT, the breast glandular section thickness of the subjects with breast structure changes was larger than that of without breast structure changes and in the fifth and sixth year of HRT, the difference was significant (P < 0.05). (3) After HRT, the serum estradiol level of subjects with mastalgia was higher than that of without mastalgia and in the second and sixth follow-up year, the difference was significant (P < 0.05). CONCLUSIONS: There is an increasing trend of the percentage of glandular tissues of the breast after HRT. There is an increasing trend of the serum estradiol level and the breast glandular section thickness among the subjects with the breast structure changes; there is an increasing trend of the serum estradiol level among the subjects with mastalgia. Mammary ultrasonography can be used to monitor breast structure changes and breast lesions during HRT.

OBJECTIVE: To detect BRCA1 and BRCA2 gene germline mutation in the Chinese breast cancer families. METHODS: Samples of peripheral blood were collected to prepare genomic DNA by conventional techniques from 15 inherited breast cancer patients from 14 breast cancer families, 76 sporadic breast cancer patients, and 100 healthy controls based on informed consent. Exons 4, 8, 11 and 18 - 20 of BRCA1, and exons 1 - 14, 17 - 24 and 27 of BRCA2, were analyzed using DNA direct sequencing. RESULTS: Six single nucleotide polymorphisms (SNPs) were found on the exon 11 of BRCA1, 2 being silent changes without change of amino acid coding, and 4 with change of amino acid coding among which 2 were polymorphic amino acid alterations and 2 were pathogenic SNPs, i.e. mutational sites. One novel BRCA1 mutation, C1196T (Pro 359 Leu), was identified in a family breast cancer patients, who was diagnosed at the age of 37. Another BRCA1 mutation, Trp 372 stop was found in a breast cancer patient who was diagnosed at the age 29. Eight SNPs were found on the exon3, 10 and 11 of BRCA2, among which 5 were silent changes and 3 were polymorphic amino acid alterations. A1093C (Asn289His) in exon 10 and A 3199G (Asn991Asp) in exon 11 being found simultaneously in the patients of 2 families but not appearing in pool DNA sample, and Asn 371 His appearing as A/C heterozygote in pool DNA sample. CONCLUSION: Two pathogenic SNPs have been found in BRCA1 and may be related to early-onset breast cancer. One of them may be a novel mutation characterized of familial breast cancer in China.
