目的探讨无精症患者的遗传因素与性激素水平的关系。方法选取本院2015年7月至2019年9月被确诊为无精症的113例患者作为试验组,30例精子数量正常人作为对照组,分别进行外周血染色体核型、Y染色体AZF微缺失以及性激素检测。结果在113例无精症患者中检出染色体异常核型36例(31.9%),异常核型具体如下:47,XXY共21例(58.3%)、性反转共6例(16.7%)、易位共1例(2.8%)、倒位共2例(5.6%)、Y缺失共1例(2.8%)、性染色体嵌合共1例(2.8%)、染色体多态共4例(11.1%),对照组未检出异常,试验组患者的染色体核型异常率明显高于对照组,差异有统计学意义(P<0.05)。试验组Y染色体AZF微缺失16例(14.2%),其中AZFa缺失1例(6.3%),AZFb缺失2例(12.5%),AZFc缺失6例(37.5%),AZFb+AZFc缺失4例(25.0%),AZFa+AZFb+AZFc缺失3例(18.8%),对照组未见异常。试验组患者的AZF微缺失异常率明显高于对照组,差异有统计学意义(P<0.05)。试验组的促卵泡生成素(FSH)、促黄体生成素(LH)与催乳素(PRL)水平均显著高于对照组,试验组患者的睾酮(T)水平显著低于对照组,差异有统计学意义(P<0.05)。异常染色体核型患者中47,XXY(Klinefelter综合征)发生率最高。异常核型患者中46,XX(性反转)的发生率仅次于47,XXY。6例性反转患者染色体核型均为女性核型(46,XX),其LH、FSH、PRL水平明显高于对照组,差异有统计学意义(P<0.05);试验组中其他染色体异常核型患者的LH、FSH、PRL、T水平与对照组比较,差异无统计学意义(P>0.05)。结论染色体核型异常、Y染色体AZF微缺失、性激素水平异常与无精症密切相关。因此对无精患者进行染色体核型、Y染色体AZF微缺失以及性激素联合检测,能更加科学、有效地了解患者病情,有助于为后续的生殖治疗提供合理的临床方案。  相似文献

BackgroundThe use of repetitive transcranial magnetic stimulation (rTMS) as both therapeutic and experimental tools has grown enormously over the past decade. However, variability in response to rTMS is one challenge that remains to be solved. Estrogen can impact neural plasticity and may also affect plastic changes following rTMS. The present study investigated whether estrogen levels influence the neurophysiological effects of high-frequency (HF) rTMS in the left dorsolateral prefrontal cortex (DLPFC).HypothesisIt was hypothesised that individuals with higher endogenous estrogen would demonstrate greater rTMS-induced changes in cortical reactivity.Methods29 healthy adults (15M/14F) received HF-rTMS over left DLPFC. Females attended two sessions, one during a high-estrogen (HE) phase of the menstrual cycle, another during a low-estrogen (LE) phase. Males attended one session. Estrogen level was verified via blood assay. TMS-EEG was used to probe changes in cortical plasticity and comparisons were made using cluster-based permutation statistics and Bayesian analysis.ResultsIn females, a significant increase in TMS-evoked P60 amplitude, and decrease in N45, N100 and P180 amplitudes was observed during HE. A less pervasive pattern of change was observed during LE. No significant changes in TEPs were seen in males. Between-condition comparisons revealed higher likelihood of the change in N100 and/or P180 being larger in females during HE compared to both females during LE and males.ConclusionsThese preliminary findings indicate that a greater neuroplastic response to prefrontal HF-rTMS is seen in women when estrogen is at its highest compared to men, suggesting that endogenous estrogen levels contribute to variability in response to HF-rTMS.  相似文献

【目的】探讨促性腺激素释放激动剂(GnRH-α)联合宫内放置左炔诺孕酮宫内缓释系统(LNG-IUS)对子宫内膜异位症(EMT)患者术后复发、痛经程度及性激素、糖抗原125(CA125)水平的影响。【方法】选取在陕西省宝鸡市眉县人民医院拟行腹腔镜手术的EMT患者107例,按照随机数表法分为观察组(n=54)和对照组(n=53)。观察组术后给予GnRH-a治疗3个周期,并宫内放置LNG-IUS,对照组术后仅给予GnRH-α治疗3个周期。比较两组患者术前、术后不同时间的痛经程度(VAS评分)、血清CA125、雌二醇(E2)、卵泡刺激素(FSH)、促黄体生成素(LH),随访24个月,统计患者的复发情况。【结果】术后3个月、12个月及24个月,观察组患者的VAS评分均显著低于对照组(P<0.05);两组患者手术前后E2、FSH、LH水平比较差异均无统计学意义(P>0.05);两组患者术前血清CA125水平比较差异无统计学意义(P>0.05);术后12个月,观察组患者的血清CA125水平显著低于对照组(P<0.05)。术后随访24个月,观察组患者复发率为1.87%(1/53),显著低于对照组的12.96%(7/54)(P<0.05),其差异有统计学意义(χ2=4.744,P=0.029)。【结论】EMT患者术后宫内放置LNOIUS,可减少复发,降低血清CA125水平,缓解痛经,值得临床推广应用。  相似文献

This prospective study aimed to compare and evaluate changes in hormones of the thyroid axis affected by tracheostomy due to surgical treatment in patients with oral cancer.The patients were evaluated with regard to serum levels of the thyroid axis — free T3/triiodothyronine (fT3) and free T4/thyroxine (fT4), as well as thyroid-stimulating hormone (TSH) — at fixed perioperative time points: during the tumor staging about 1 week before operation, immediately before and within 6 h after operation, 2 days after operation, and about 10 days after operation. Additionally, data on the patients’ characteristics (age, gender), relevant secondary diagnoses, duration of ventilation in the intensive care unit, and perioperative complications were obtained and analyzed.In total, 51 patients with an average age of 68.29 years (±11.82) were included. Analyses of thyroid hormones directly before and after tracheostomy showed a significant postoperative decrease in circulating TSH (p = 0.005) and fT3 (p < 0.001), whilst a significant increase in fT4 values (p < 0.001) was found. Nine patients showed perioperative complications, such as infection, emphysema, or requiring a revision operation. Eleven patients were diagnosed with a cardiac problem or suffered from agitation after operation.Within the limitations of the study it seems that hormonal changes following tracheostomy in critically ill patients should be monitored and thyroid hormone adjustment should be taken into account because the latter might lead to lower mortality and morbidity during hospitalization in these patients.Clinical trial registration numberDRKS00023942.  相似文献

Di(2-ethylhexyl) phthalate (DEHP) is a known endocrine disruptor and diisononyl phthalate (DiNP) is a common DEHP replacement chemical. However, little is known about late-life consequences due to DEHP or DiNP exposure during adulthood. Thus, this study tested the hypothesis that adult exposure to DEHP or DiNP affects female reproductive parameters during late-life in female mice. Female CD-1 mice (age 39–40 days) were dosed with either vehicle control, DEHP (20 μg/kg/day–200 mg/kg/day), or DiNP (20 μg/kg/day–200 mg/kg/day) for 10 days and breeding trials were conducted at 12 and 15 months post-dosing. Further, ovaries and sera were collected at 12, 15, and 18 months post-dosing. DEHP and DiNP disrupted estrous cyclicity, increased pregnancy loss, decreased fertility, altered the sex ratio of pups, altered ovarian follicle populations, and disrupted hormone levels. Collectively, these data show that short-term exposure to DEHP or DiNP during adulthood has long-term consequences in late-life.  相似文献

目的 探讨小剂量甲状腺素补充治疗对慢性肾脏疾病患者的甲状腺激素水平、营养不良及左心功能的影响.方法 湖南省人民医院2013年2月至2015年2月间收治的慢性肾脏疾病患者210例,A组为eGFR< 15mL ·(min·1.73m2)-1的患者(n=70),B组为15< eGFR<30mL·(min·1.73m2)-1的患者(n=70),C组为30 <eGFR <60mL·(min·1.73m2)-1的未透析患者(n=70).选择同期本院体检的正常人群为正常对照组(D组,n =70).收集4组患者血液、生化临床资料,检测游离三碘甲状腺原氨酸(free triiodothyronine,FT3)、游离甲状腺素(freethyroxine,FT4)、促甲状腺激素(thyroid stimulating hormone,TSH)、C反应蛋白(C reactive protein,CRP)、左心室射血分数(left ventricular ejection fraction,LVEF)及左心室质量指数(Left ventricular mass index,LVMI),并计算主观综合性营养评估法(subjective global assessment of nutritional act,SGA)等指标.每组根据甲状腺激素水平分为正常组Ⅰ、异常组Ⅱ,观察各组间各指标差异,再给予异常组小剂量甲状腺激素干预后观察各项指标改变.结果 A、B、C组FT3均显著低于D组(P<0.05),低T3综合征的发生率随eGFR下降而升高;正常组Ⅰ与异常组Ⅱ相比,ALB、CRP、SGA、LVEF、LVMI比较有显著差异(P<0.05);异常组的FT3与eGFR、SGA、ALB、LVEF呈显著正相关(r=0.912,P<0.001;r =0.721,P<0.001;r =0.810,P<0.001;r=0.903,P<0.001);FT3与CRP、LVMI呈负相关(r=-0.981,P<0.001;r=-0.442,P<0.001);异常亚组给予小剂量甲状腺素治疗后FT3及LVEF较治疗前明显改善(P<0.05),治疗后eGFR水平只有C2组患者有提高(P<0.05).结论 甲状腺素水平下降与肾功能严重程度相关,以血清FT3水平降低为主;低水平FT3与营养、左心功能有显著相关性;予以小剂量的甲状腺激素治疗后的低T3及亚临床甲减者的左心收缩功能有提高,中度肾功能损伤的患者eGFR有提高.  相似文献
