多囊卵巢综合征与相关基因多态性的研究进展 总被引:1,自引:1,他引:0
多囊卵巢综合征(polycystic ovary syndrome,PCOS)是一种常见的异质性内分泌疾病,是导致女性不孕的常见因素。该病的病因仍不明了,遗传因素在其发病中起一定作用。分子遗传学研究表明,PCOS发生机制与影响甾体激素、促性腺激素、性腺激素和胰岛素的合成和代谢以及物质能量调节的基因密切相关,其中一些关键基因,如胆固醇侧链裂解(CYP11A)基因、芳香化酶(CYP19)基因、17β-类固醇脱氢酶(17β-HSD)基因、促卵泡素基因受体(FSHR)基因、雄激素受体(AR)基因、雌激素受体(ER)基因、性激素结合球蛋白(SHBG)基因、过氧化物体增殖激活受体(PPARγ)基因、脂联素(adiponectin)基因、胰岛素基因的微卫星(INS VNTR)、胰岛素受体(INSR)基因、胰岛素受体底物蛋白(IRS)基因等的多态性尤其是单核苷酸多态性可能起重要的作用。 相似文献

多囊卵巢综合征促排卵方案的现状 总被引:6,自引:0,他引:6
多囊卵巢综合征(PCOS)患者最常表现闭经或月经稀发,无排卵和不孕。生育年龄有生育要求的治疗以促排卵、调节代谢为主。PCOS促排卵的结局易造成多卵泡发育,卵巢过度刺激综合征(OHSS)、多胎妊娠的发生率较高,或者对促排卵药物不反应或卵泡期过长,提早黄素化等。目前应用于临床的促排卵药物及促排卵方案较多。本文将针对目前PCOS的促排方案加以综述和比较。 相似文献

The study aimed to investigate insulin resistance (IR) status in polycystic ovary syndrome (PCOS) women with normal glucose tolerance (NGT), and further to evaluate feasible diagnostic method for those patients. Three hundred and twenty-five PCOS women with NGT and ninety-five healthy age-matched controls were recruited with Rotterdam criterion and 75 g oral glucose tolerance test (OGTT). IR status was estimated following a glycemic and insulinemic OGTT (0, 30, 60, 120, and 180 min). A modified HOMA-IR formula was applied to each time-course value of glycemia and insulinemia. The predictive performance of each IR index was analyzed with the use of ROC curves. Compared with healthy controls, both non-obese and obese PCOS patients with NGT had a higher BMI, serum glucose, insulin value (p?.05). The best predictive index of IR in non-obese PCOS-NGT was a HOMA-M30 value of 20.36 or more (AUC: 0.753). In obese PCOS-NGT population, the best predictive performance was obtained by a HOMA-M60 value of 32.17 or more (AUC: 0.868). IR was common in Chinese PCOS women with NGT, and the early assessment of IR should be heeded. We recommended HOMA-M30 (Cutoff: 20.36) and HOMA-M60 (Cutoff: 32.17) as the best predictive parameters for non-obese and obese PCOS-NGT patients, respectively. 相似文献

Objective
Comparing oxytocin level and some other parameters between infertile women with or without polycystic Ovary Syndrome (PCOS), to evaluate the correlation between oxytocin with anti-mullerian hormone (AMH), Body Mass Index (BMI) and insulin resistance (IR).Materials and methods
This cross–sectional study was performed on 80 PCOS and 81 non-PCOS women as the control group. Oxytocin, various hormones, Oral glucose tolerance test (OGTT) and Homeostatic model assessment of insulin resistance (HOMA-IR) were compared between two groups. Correlations between parameters were assessed by the spearman's rank correlation coefficient. Cutoff values for oxytocin and AMH in PCOS were calculated by the ROC-Curve and DeLong method.Results
The mean oxytocin level was statistically lower in the case group (p ≤ 0.001). The mean BMI, AMH, HOMA-IR, fasting insulin and insulin 2-h after 75-g glucose were significantly higher in the PCOS group. Oxytocin was negatively correlated to AMH when evaluated for all participants or only among controls. Moreover oxytocin was negatively correlated to HOMA-IR among all participants. However the relationship between oxytocin and BMI was not statistically significant. The calculated cutoff value for oxytocin was 125 ng/L and for AMH was 3.6 ng/mL in the PCOS group.Conclusion
The mean oxytocin level in the PCOS infertile women was lower than non-PCOS women. Oxytocin showed a significant reverse correlation with AMH and HOMA-IR. 相似文献13.

Purpose
To describe the long noncoding RNA (lncRNA) profiles in cumulus cells isolated from polycystic ovary syndrome (PCOS) patients by employing a microarray and in-depth bioinformatics analysis. This information will help us understand the occurrence and development of PCOS.Methods
In this study, we used a microarray to describe lncRNA profiles in cumulus cells isolated from ten patients (five PCOS and five normal women). Several differentially expressed lncRNAs were chosen to validate the microarray results by quantitative RT-PCR (qRT-PCR). Then, the differentially expressed lncRNAs were classified into three subgroups (HOX loci lncRNA, enhancer-like lncRNA, and lincRNA) to deduce their potential features. Furthermore, a lncRNA/mRNA co-expression network was constructed by using the Cytoscape software (V2.8.3, http://www.cytoscape.org/).Results
We observed that 623 lncRNAs and 260 messenger RNAs (mRNAs) were significantly up- or down-regulated (≥2-fold change), and these differences could be used to discriminate cumulus cells of PCOS from those of normal patients. Five differentially expressed lncRNAs (XLOC_011402, ENST00000454271, ENST00000433673, ENST00000450294, and ENST00000432431) were selected to validate the microarray results using quantitative RT-PCR (qRT-PCR). The qRT-PCR results were consistent with the microarray data. Further analysis indicated that many differentially expressed lncRNAs were transcribed from chromosome 2 and may act as enhancers to regulate their neighboring protein-coding genes. Forty-three lncRNAs and 29 mRNAs were used to construct the coding-non-coding gene co-expression network. Most pairs positively correlated, and one mRNA correlated with one or more lncRNAs.Conclusions
Our study is the first to determine genome-wide lncRNA expression patterns in cumulus cells isolated from PCOS patients by microarray. The results show that clusters of lncRNAs were aberrantly expressed in cumulus cells of PCOS patients compared with those of normal women, which revealed that lncRNAs differentially expressed in PCOS and normal women may contribute to the occurrence of PCOS and affect oocyte development.15.

Objective To investigate the efficacy of a combined oral contraceptive containing 30 µg ethinyloestradiol and 3 mg drospirenone in the treatment of hyperandrogenism affecting women with the polycystic ovary syndrome (PCOS).Methods Prospective open study of 20 women for six cycles. At the beginning and at the end of the study the following values were determined: the Ferriman–Gallwey (F–G) score, body mass index, waist/hip ratio, serum levels of testosterone, SHBG, immune reactive insulin (IRI), glucose, the free androgenic index, and insulin resistance (HOMA-IR).Results All 20 women completed six cycles of therapy. The medication was well tolerated. At the end of the study there was a significant improvement of hirsutism, expressed in the decrease of the F–G score, accompanied by a decrease of testosterone and an increase of SHBG values. The carbohydrate metabolism was not affected significantly.Conclusion The combined oral contraceptive containing 30 µg ethinyloestradiol and 3 mg drospirenone is an effective drug in the treatment of hyperandrogenism in women with PCOS; it elicits few side effects and does not significantly influence insulin resistance. 相似文献

We report a young woman of normal body weight who was diagnosed with polycystic ovary syndrome (PCOS) and had an odd variation
of 75 g oral glucose tolerance test (OGTT). This woman underwent the 75 g OGTT to evaluate the association between PCOS and
insulin secretion capacity. Although the blood sugar levels were within normal range before the OGTT load test, we noted an
odd variation of insulin response in which a condition of hyperinsulinemia after the load test was followed suddenly by hypoglycemia.
Hyperandrogenism in the PCOS patient and insulin resistance indicated by 75 g OGTT suggest that insulin may influence the
ovary and that there could be an association between this disease and insulin resistance. The insulinogenic index in this
case showed higher than normal values, demonstrating that there was a positive correlation between hyperinsulinemia and insulin
resistance. This patient experienced ovulation followed by pregnancy after treatment with an herbal medicine called Shakuyaku–Kanzo–To.
We believed that identifying the subset of PCOS woman who is insulin resistant may be useful, as this resistance could be
import in terms of follow-up and future exploration. 相似文献
