基础雄激素及卵泡液雄激素水平与卵巢反应性及妊娠结局关系的探讨

目的:探讨基础雄激素及卵泡液雄激素水平与卵巢反应性及妊娠结局的关系。方法:选取行IVF/ICSI助孕治疗的130例不孕症女性,将研究对象分为卵巢储备功能低下组、卵巢储备功能正常组。ELISA法检测基础雄激素及卵泡液中睾酮浓度。结果:卵巢储备功能低下组中,卵巢低反应组与正常反应组的基础雄激素水平比较,差异有统计学意义(P=0.037);两组卵泡液中雄激素水平比较,差异无统计学意义(P=0.475)。卵巢储备功能正常组中,卵巢低反应组与正常反应组的基础雄激素水平及卵泡液雄激素水平比较,差异均无统计学意义(P=0.426,P=0.594)。20例进行新鲜周期移植的卵巢储备功能低下患者中,未妊娠组与妊娠组基础雄激素水平及卵泡液中雄激素水平比较,差异均无统计学意义(P=0.400,P=0.656)。89例进行新鲜周期移植的卵巢储备功能正常患者中,未妊娠组与妊娠组的基础雄激素水平及卵泡液中雄激素水平比较,差异均无统计学意义(P=0.380,P=0.930)。结论:卵巢储备功能低下患者,基础雄激素水平与卵巢反应性相关,而与妊娠结局无关;卵泡液中雄激素水平与卵巢反应性和妊娠结局无关。卵巢储备功能正常患者,基础雄激素和卵泡液中雄激素均与卵巢反应性及妊娠结局无关。     

PCOS患者AMH水平与肥胖、睾酮水平、胰岛素抵抗的相关性分析

目的比较BMI正常与否多囊卵巢综合征（PCOS）患者抗苗勒管激素（AMH）水平差异,分析AMH水平与患者内分泌及代谢指标的相关性。方法209例PCOS患者按BMI正常与否分为肥胖组（BMI≥25,77例）和正常体重组（BMI＜25,132例）。测定患者血清AMH、卵泡刺激素（FSH）、黄体生成素（LH）、睾酮、空腹血糖和空腹胰岛素、TC、TG和LDL-C水平,计算稳态模型胰岛素抵抗指数（HOMA-IR）,比较两组患者AMH水平差异,并分析AMH水平与各临床指标的相关性。结果肥胖组患者AMH水平低于正常体重组[（8.92±4.70）ng/mlvs（10.99±5.40）ng/ml,P＜0.05],空腹血糖、空腹胰岛素、HORM-IR、TG、LDL-C水平均高于正常体重组（均P＜0.05）,LH、LH/FSH均低于正常体重组（均P＜0.05）。总PCOS组患者AMH水平与患者BMI、空腹胰岛素水平、HOMA-IR呈负相关,与LH、LH/FSH呈正相关,与睾酮不相关。肥胖组患者AMH水平与各临床指标均不相关,正常体重组患者AMH水平与LH/FSH、睾酮水平呈正相关。当控制BMI因素后,总PCOS组患者AMH水平与LH/FSH及睾酮水平呈正相关,与空腹胰岛素水平、HORM-IR不相关。结论肥胖和胰岛素抵抗可能使PCOS患者AMH水平降低;当控制BMI因素后,PCOS患者AMH水平与睾酮水平呈正相关,与胰岛素及HOMA-IR不相关。     

Lower serum DHEAS levels are associated with a higher degree of physical disability and depressive symptoms in middle-aged to older African American women

BACKGROUND: Changes in androgen levels and associations with chronic disease, physical and neuropsychological function and disability in women over the middle to later years of life are not well understood and have not been extensively studied in African American women. AIMS: The present cross-sectional analysis reports such levels and associations in community dwelling, African American women aged 49-65 years from St. Louis, Missouri. METHODS: A home-based physical examination and a health status questionnaire were administered to randomly sampled women. Body composition (DEXA), lower limb and hand-grip muscle strength, physical and neuropsychological function and disability levels were assessed. Blood was drawn and assayed for total testosterone (T), sex hormone-binding globulin (SHBG), dehydroepiandrosterone-sulfate (DHEAS), oestradiol (E2), adiponectin, leptin, triglycerides, glucose, C-reactive protein (CRP) and cytokine receptors (sIL2r, sIL6r, sTNFr1 and sTNFr2). Multiple linear regression modelling was used to identify the best predictors of testosterone, DHEAS and free androgen index (T/SHBG). RESULTS: Seventy-four percent of women were menopausal and a quarter of these were taking oestrogen therapy. DHEAS and E2 declined between the ages of 49 and 65 years, whereas total T, SHBG and FAI remained stable. Total T and DHEAS levels were strongly correlated. In this population sample there were no independent associations of either total T or FAI with indicators of functional limitations, disability or clinically relevant depressive symptoms. Unlike total T and FAI, lower DHEAS levels were independently associated with both higher IADL scores (indicating a higher degree of physical disability) and higher CESD scores (indicating a higher degree of clinically relevant depressive symptoms). CONCLUSION: There is an age-related decline in serum DHEAS in African American women. Lower DHEAS levels appear to be associated with a higher degree of physical disability and depressive symptoms in this population.     

龙牡壮骨颗粒对小鼠性激素水平的影响

摘 要 目的:探讨龙牡壮骨颗粒对性激素水平的影响。方法: 昆明小鼠雌雄各30只,以该制剂溶于水制成溶液剂为供试药,以双蒸水为空白对照。受试小鼠按性别随机分为龙牡壮骨颗粒雌性高、等效剂量组和龙牡壮骨颗粒雄性高、等效剂量组,给药14 d,观察对血清睾酮、雌二醇含量和骨指标的影响。结果:龙牡壮骨颗粒能显著提高小鼠骨干重、骨密度、骨量,等效剂量龙牡壮骨颗粒组还能明显提高雄性小鼠骨湿重（P=0.022）,等效剂量龙牡壮骨颗粒对小鼠性激素水平无影响（P=0.855）。高剂量龙牡壮骨颗粒显著降低雄性小鼠雌二醇水平（P=0.048）。结论: 与临床剂量等效的龙牡壮骨颗粒对小鼠骨质有增强作用,同时对小鼠性激素水平无影响。

Carbamazepine-exposure during gestation and lactation affects pubertal onset and spermatic parameters in male pubertal offspring

Carbamazepine (CBZ) is an anti-epileptic drug that acts on Leydig cells, affecting steroidogenesis and causes fetal malformation. The aim of this study was to investigate the effects of CBZ on male sexual maturation and other male parameters. Rat dams were treated with CBZ during pregnancy and breastfeeding. The anogenital distance (AGD) and the anogenital index (AGI) were obtained. Testicular descent and preputial separation were also evaluated. The offspring was euthanized at PND 41 and 63. The accessory glands were weighed and the testes were collected for histopathological, morphometric and sterological analyses. The numerical density of Leydig cells and hormone dosage were obtained. CBZ caused an increase of AGI and a delay of testicular descent and of preputial separation. CBZ also caused a decrease of testosterone level and of sperm count and an increase of abnormal sperm. These results indicate that CBZ delays puberty onset and affects steroidogenesis and sperm quality.
