    脂肪组织(AT),主要由脂肪细胞组成,在血脂控制中起着至关重要的作用,新陈代谢,和能量储存。一旦被认为是代谢惰性的,AT现在被认为是调节食物摄入的动态内分泌器官,能量稳态,胰岛素敏感性,体温调节,和免疫反应。这篇综述探讨了脂联素的多方面作用,AT释放的主要脂肪因子,在葡萄糖和脂肪酸代谢中。我们探索脂联素的调节机制,其生理效应及其作为2型糖尿病等代谢性疾病治疗靶点的潜力,心血管疾病和脂肪肝疾病。此外,我们分析了各种膳食模式的影响,特定的营养素,和身体活动对脂联素水平的影响,强调改善代谢健康的策略。我们的全面综述提供了有关脂联素的关键功能及其在维持全身代谢稳态中的重要性的见解。
    Adipose tissue (AT), composed mainly of adipocytes, plays a critical role in lipid control, metabolism, and energy storage. Once considered metabolically inert, AT is now recognized as a dynamic endocrine organ that regulates food intake, energy homeostasis, insulin sensitivity, thermoregulation, and immune responses. This review examines the multifaceted role of adiponectin, a predominant adipokine released by AT, in glucose and fatty acid metabolism. We explore the regulatory mechanisms of adiponectin, its physiological effects and its potential as a therapeutic target for metabolic diseases such as type 2 diabetes, cardiovascular disease and fatty liver disease. Furthermore, we analyze the impact of various dietary patterns, specific nutrients, and physical activities on adiponectin levels, highlighting strategies to improve metabolic health. Our comprehensive review provides insights into the critical functions of adiponectin and its importance in maintaining systemic metabolic homeostasis.

    目的:只有少数病例报道描述了异位卵巢组织移植(OTT),其唯一目的是恢复卵巢功能。
    方法:病例报告和文献复习报道异位OTT病例,目的仅是恢复卵巢内分泌功能。在有子宫切除术和双侧卵巢切除术的宫颈癌病史的癌症幸存者中,由于她对激素替代疗法(HRT)的耐受性较差,我们进行了异位OTT在骨盆皮下\"口袋\"在OT冷冻储存17年后。
    结果:在OTT后3个月开始出现周期性卵巢内分泌功能,患者自我描述的生活质量立即得到改善。在19个月后进行了第二次OTT,由于潮热复发和FSH增加。尽管有周期性的内分泌功能,孕酮水平一直很低,导致相对的高雌激素状态。
    结论:在未来,异位OTT的适应症可以替代HRT传播。然而,我们的数据表明,异位移植环境对黄体发育不太有利,需要进一步的研究来分析异位移植物的最佳位置,卵巢皮质碎片移植的最佳数量,以及恶性残留病复发的潜在风险。
    OBJECTIVE: Only a few case reports have described heterotopic ovarian tissue transplantation (OTT) with the only objective of restoring ovarian function.
    METHODS: Case report and review of the literature for reporting cases of heterotopic OTT with the only aim of restoring ovarian endocrine function. In a cancer survivor woman with a history of hysterectomy and bilateral oophorectomy for cervical cancer and because she poorly tolerated hormone replacement therapy (HRT), we performed a heterotopic OTT in a pelvic subcutaneous \"pocket\" after an OT cryostorage of 17 years.
    RESULTS: A cyclic ovarian endocrine function started 3 months after OTT with an immediate patient self-described improvement of her quality of life. A second OTT was performed 19 months after, due to hot flushes recurrence and FSH increase. Despite a cyclic endocrine function, progesterone levels have always been low, resulting in a relative hyperoestrogenism state.
    CONCLUSIONS: In the future, the indications of heterotopic OTT could be spread in alternative to HRT. However, our data suggest that the heterotopic graft environment is less favorable to corpus luteum development, and further studies are needed to assay the best site of heterotopic graft, the optimal number of ovarian cortex fragments to graft, and the potential risk of relapse in case of malignant residual disease.

    根据国家健康和营养检查调查(NHANES)数据库的数据,评估生命必需8(LE8)及其分量表与男性生化雄激素缺乏症(MBAD)和总睾酮的关联。
    提取了2013-2016年NHANES中20岁或以上男性的数据。LE8评分根据美国心脏协会的定义计算。使用精确的同位素稀释液色谱法在NHANES中测量总睾酮(TT)值。MBAD定义为血清TT<300ng/dL。进行了单变量和多变量分析。增加倾向评分匹配(PSM)和匹配后的加权回归作为敏感性分析。广义加法模型,平滑曲线拟合,并使用递归算法确定潜在的拐点。采用对数似然比检验的分段回归模型对非线性效应进行量化。
    总共包括3094名男性和20岁或以上的参与者。在他们当中,805名男性被诊断为MBAD。在调整了多变量模型中的混杂因素后,LE8与MBAD(OR0.96,P<0.001)和TT(β2.7,P<0.001)独立相关。即使在PSM之后,该关联仍保持稳健。揭示LE8行为评分与MBAD和TT的非线性关系。
    LE8是MBAD的独立保护因子,是促进男性内分泌性功能的可行途径。
    UNASSIGNED: To evaluate the association of Life\'s Essential 8 (LE8) and its subscales with male biochemical androgen deficiency (MBAD) and total testosterone based on the data from the national health and nutrition examination survey (NHANES) database.
    UNASSIGNED: Data of males aged 20 years or older from NHANES of 2013-2016 were extracted. LE8 score was calculated based on American Heart Association definitions. Total testosterone (TT) values were measured in NHANES using precise isotope dilution liquid chromatography. MBAD was defined as serum TT of <300 ng/dL. Univariate and multivariable analyses were conducted. Propensity score matching (PSM) and weighted regression after matching were added as sensitivity analyses. The generalized additive model, smooth curve fitting, and the recursive algorithm were used to determine the potential inflection points. Piecewise regression models with log-likelihood ratio test were used to quantify nonlinear effects.
    UNASSIGNED: A total of 3094 participants who were males and aged 20 years or above were included. Out of them, 805 males were diagnosed with MBAD. After adjusting the confounders in the multivariable model, LE8 was independently associated with MBAD (OR 0.96, P < 0.001) and TT (β 2.7, P < 0.001). The association remained robust even after PSM. The non-linear relationship of LE8 behaviors score with MBAD and TT was revealed.
    UNASSIGNED: LE8 was an independent protective factor of MBAD and a feasible approach to promote male endocrine sexual function.

    目标:尽管在2014年引入了运动中相对能量不足(RED-s),但有证据表明,男性耐力运动员仍然存在低能量可用性(LEA)的高患病率。先前的研究结果表明,能量可用性(EA)状态与内分泌功能受损密切相关,例如瘦素减少,三碘甲状腺原氨酸(T3),和胰岛素,和骨质流失增加。本研究旨在报告当前的EA状态,训练有素的爱尔兰男性耐力运动员的内分泌功能和骨骼健康。
    方法:在这项横断面研究中,参与者(n=3名铁人三项运动员;n=10名跑步者)在比赛季节使用基于实验室的措施完成了为期7天的测试期,为了确定EA状态,激素水平和骨代谢率。获得血清血样以评估激素水平和骨代谢标志物。
    结果:76.9%的运动员平均EA为<30kcal/kg瘦体重(LBM)/天。LEA和低碳水化合物摄入量之间有很强的关联,较低的LBM。平均胰岛素水平,IGF-1和瘦素显著低于其参考范围。β-CTX的平均浓度升高和P1NP:β-CTX的平均比率<100表明骨吸收状态。
    结论:EA级别,碳水化合物的摄入量,训练有素的男性耐力运动员的激素状态和骨代谢状况令人担忧。根据这项研究的结果,建议对整个赛季的EA进行更频繁的评估,以监测男性耐力运动员的状况,结合特定于EA的营养教育和相关风险。
    OBJECTIVE: Despite the introduction of Relative Energy Deficiency in Sport (RED-s) in 2014, there is evidence to suggest that male endurance athletes still present with a high prevalence of low energy availability (LEA). Previous findings suggest that energy availability (EA) status is strongly correlated with impairments in endocrine function such as reduced leptin, triiodothyronine (T3), and insulin, and elevated bone loss. This study aimed to report the current EA status, endocrine function and bone health of highly trained Irish male endurance athletes.
    METHODS: In this cross-sectional study, participants (n = 3 triathletes; n = 10 runners) completed a 7-day testing period during the competition season using lab-based measures, to ascertain EA status, hormone level and rates of bone metabolism. Serum blood samples were obtained to assess hormone levels and markers of bone metabolism.
    RESULTS: Mean EA was < 30 kcal/kg lean body mass (LBM)/day in 76.9% of athletes. There was a strong association between LEA and low carbohydrate intake, and lower LBM. Mean levels of insulin, IGF-1 and leptin were significantly lower than their reference ranges. Elevated mean concentrations of β-CTX and a mean P1NP: β-CTX ratio < 100, indicated a state of bone resorption.
    CONCLUSIONS: The EA level, carbohydrate intake, hormone status and bone metabolism status of highly trained male endurance athletes are a concern. Based on the findings of this study, more frequent assessment of EA across a season is recommended to monitor the status of male endurance athletes, in conjunction with nutritional education specific to EA and the associated risks.

    不同冬季围场管理对北海道纯种断奶和一岁育苗的影响,Japan,冬天非常冷,关于生理功能,研究了内分泌功能和生长。他们分为两组;那些在围场中保持在户外22小时(22小时组),那些在白天保持在户外7小时,并使用马步行者进行1小时的步行运动(7小时W组),以及每天旅行距离的变化,体温(BT),心率(HR),HR变异性(HRV),比较两组出生11月至1岁1月的内分泌功能和生长参数。通过使用骑马者,7hrW组的行进距离可以与22hr组的行进距离几乎相同。1月22hr组的体重增加率低于7hr+W组。此外,观察到BT和HR较低,和HRV分析显示高频功率谱密度增加,表明副交感神经活动占主导地位。而且,尽管环境寒冷,但未观察到循环皮质醇和甲状腺素的变化。另一方面,7hr+W组比22hr组有更高的催乳素和胰岛素样生长因子,皮质醇和甲状腺素也增加。本研究的生理和内分泌研究结果表明,7小时W组的管理可有效促进冬季的生长和维持新陈代谢。
    Effects of different winter paddock management of Thoroughbred weanlings and yearlings in Hokkaido, Japan, which is extremely cold in winter, on physiological function, endocrine function and growth were investigated. They were divided into two groups; those kept outdoors for 22 hr in the paddock (22hr group) and those kept outdoors for 7 hr in daytime with walking exercise for 1 hr using the horse-walker (7hr+W group), and the changes in daily distance travelled, body temperature (BT), heart rate (HR), HR variability (HRV), endocrine function and growth parameters were compared between the two groups from November at the year of birth to January at 1 year of age. The 7hr+W group could travel almost the same distance as the 22hr group by using the horse-walker. The 22hr group had a lower rate of increase in body weight than the 7hr+W group in January. In addition, lower in BT and HR were observed, and HRV analysis showed an increase in high frequency power spectral density, indicating that parasympathetic nervous activity was dominant. And also, changes in circulating cortisol and thyroxine were not observed despite cold environment. On the other hand, the 7hr+W group had higher prolactin and insulin like growth factor than the 22hr group in January, and cortisol and thyroxine were also increased. Physiological and endocrinological findings from the present study indicate that the management of the 7hr+W group is effective in promoting growth and maintaining metabolism during the winter season.

    探讨营养补充剂在改善多囊卵巢综合征(PCOS)患者糖脂代谢和内分泌功能方面的比较有效性。
    在PubMed,Embase,科克伦图书馆,和WebofScience从他们的机构到2023年3月15日。然后,文献筛选,数据提取,并进行网络荟萃分析。本研究在PROSPERO注册(注册号CRD42023441257)。
    本研究纳入了41篇涉及2,362例患者的文章。网络荟萃分析表明,肉碱,肌醇,与安慰剂相比,益生菌降低了体重和体重指数(BMI),和肉碱优于其他补充剂(SUCRAs:96.04%,97.73%,分别)。Omega-3降低空腹血糖(FBG)(SUCRAs:93.53%),和铬降低空腹胰岛素(FINS)(SUCRAs:72.90%);两者在改善胰岛素抵抗指数(HOMA-IR)方面均优于安慰剂,铬比Omega-3更有效(SUCRAs:79.99%)。硒可有效提高定量胰岛素敏感性指数(QUICKI)(SUCRAs:87.92%)。辅酶Q10在降低甘油三酯(TG)方面最有效,总胆固醇(TC),和低密度脂蛋白胆固醇(LDL-C)水平(SUCRAs:87.71%,98.78%,98.70%,分别)。铬和益生菌降低TG水平,而铬和维生素D降低TC水平。高密度脂蛋白胆固醇(HDL-C)无显著差异,总睾酮(TT),性激素结合球蛋白(SHBG),营养补充剂和安慰剂之间的C反应蛋白(CRP)。
    肉碱在减轻体重方面相对有效,而铬,Omega-3和硒有利于改善糖代谢。同时,辅酶Q10对改善脂质代谢更有效。然而,可能存在出版偏见,需要更多高质量的临床随机对照试验。
    UNASSIGNED: To explore the comparative effectiveness of nutritional supplements in improving glycolipid metabolism and endocrine function in patients with polycystic ovary syndrome (PCOS).
    UNASSIGNED: Randomized controlled clinical trials on the effects of nutritional supplements in PCOS patients were searched in PubMed, Embase, Cochrane Library, and Web of Science from their establishments to March 15, 2023. Then, literature screening, data extraction, and network meta-analysis were performed. This study was registered at PROSPERO (registration number CRD 42023441257).
    UNASSIGNED: Forty-one articles involving 2,362 patients were included in this study. The network meta-analysis showed that carnitine, inositol, and probiotics reduced body weight and body mass index (BMI) compared to placebo, and carnitine outperformed the other supplements (SUCRAs: 96.04%, 97.73%, respectively). Omega-3 lowered fasting blood glucose (FBG) (SUCRAs: 93.53%), and chromium reduced fasting insulin (FINS) (SUCRAs: 72.90%); both were superior to placebo in improving insulin resistance index (HOMA-IR), and chromium was more effective than Omega-3 (SUCRAs: 79.99%). Selenium was potent in raising the quantitative insulin sensitivity index (QUICKI) (SUCRAs: 87.92%). Coenzyme Q10 was the most effective in reducing triglycerides (TG), total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C) levels (SUCRAs: 87.71%, 98.78%, and 98.70%, respectively). Chromium and probiotics decreased TG levels, while chromium and vitamin D decreased TC levels. No significant differences were observed in high-density lipoprotein cholesterol (HDL-C), total testosterone (TT), sex-hormone binding globulin (SHBG), and C-reactive protein (CRP) between nutritional supplements and placebo.
    UNASSIGNED: Carnitine was relatively effective in reducing body mass, while chromium, Omega-3, and selenium were beneficial for improving glucose metabolism. Meanwhile, coenzyme Q10 was more efficacious for improving lipid metabolism. However, publication bias may exist, and more high-quality clinical randomized controlled trials are needed.

    双酚(BPs)由于其干扰内分泌系统的能力及其在环境中的普遍存在而成为特别感兴趣的化学基团。由于其中一些具有温和的雌激素和抗雄激素作用,它们可能与多囊卵巢综合征(PCOS)的诊断有关。作用于多个组织,BP暴露可能导致代谢综合征(MetS)特征性的代谢紊乱。因此,本研究的目的是确定PCOS女性BPA类似物暴露与MetS特征之间的潜在关系.血清BPE,BPC,BPG,BPM,BPP,BPZ,BPFL,PCOS(n=135)和对照组(n=104)之间的BPBP浓度没有显着差异。然而,血清BPM和BPP浓度最高的女性更有可能被诊断为PCOS(校正OR;[95CI]0.43;[0.20;0.89],P<0.001和0.56;[0.27;0.96],因此,P=0.049)。PCOS组血清BPs浓度与MetS诊断无关。血清BPBP浓度与血清总胆固醇呈负相关(r=-0.153;P=0.019),BPE和血清睾酮(r=-0.160;P=0.014)以及BPC和HDL-胆固醇(r=-0.138;P=0.036)。BPP浓度与血清甘油三酯呈正相关(r=0.138;P=0.036)。我们的结果指出了暴露于BPM之间的潜在关联,BPP,和PCOS的诊断,随着BPBP的影响,BPE,BPC,和BPP对MetS代谢特征的影响。
    Bisphenols (BPs) have become a chemical group of special interest due to their ability to interfere with the endocrine system and their ubiquitous presence in the environment. As some of them possess mild estrogenic and anti-androgenic effects, they might be associated with the diagnosis of polycystic ovary syndrome (PCOS). Acting on multiple tissues, BPs exposure may lead to metabolic derangements characteristic for metabolic syndrome (MetS). Therefore, the aim of this study was to determine the potential relationship between exposure to some BPA analogues and features of the MetS in women with PCOS. Serum BPE, BPC, BPG, BPM, BPP, BPZ, BPFL, and BPBP concentrations did not differ significantly between the PCOS (n = 135) and the control subjects (n = 104). However, women whose serum BPM and BPP concentrations were in the highest tertile were more likely to be diagnosed with PCOS (adjusted OR; [95%CI] 0.43; [0.20; 0.89], P < 0.001 and 0.56; [0.27; 0.96], P = 0.049, consequently). Serum concentrations of BPs were not associated with the MetS diagnosis in the PCOS group. There was a negative correlation between the concentrations of serum BPBP and total serum cholesterol (r = - 0.153; P = 0.019), BPE and serum testosterone (r = - 0.160; P = 0.014) as well as BPC and HDL-cholesterol (r = - 0.138; P = 0.036). There was a positive correlation between the concentrations of BPP and serum triglycerides (r = 0.138; P = 0.036). Our results point to the potential association between exposure to BPM, BPP, and the diagnosis of PCOS, along with the impact of BPBP, BPE, BPC, and BPP on the metabolic features of the MetS.
