    目的:探讨irisin对多囊卵巢综合征(PCOS)患者卵巢胰岛素抵抗(IR)的影响及其可能的作用途径。
    方法:我们使用PoretskyL\'s方法建立了PCOS模型,然后将PCOS大鼠随机分为模型组(M)和艾瑞辛组(I),正常大鼠(N)作为对照。然后对I组大鼠注射重组irisin。然后循环空腹血糖(FBG)的水平,空腹胰岛素(FINS),观察各组IR(HOMA-IR)、PI3K/AKT和MAPK/ERK通路的稳态模型评估,以及irisin对PCOS大鼠卵巢循环HOMA-IR和PI3K/AKT和MAPK/ERK通路的影响。
    结果:与正常组相比,FBG的水平,FINS,模型组HOMA-IR明显升高(p<0.001,p<0.001,p<0.001),p-PI3K的IHC平均光密度水平,PI3K,p-AKT,和AKT(分别为p=0.015,p=0.010,p=0.005和p=0.009)以及PI3K和AKT的mRNA浓度(分别为p=0.001和p=0.005)降低,而p-ERK的平均光密度水平,ERK(分别为p=0.011和p=0.013)和ERK的mRNA浓度(p<0.001)在卵巢中增加。在艾瑞辛干预之后,与模型组相比,FBG的水平,FINS,irisin组大鼠HOMA-IR显著降低(p=0.001,p<0.001,p<0.001),p-PI3K的IHC平均光密度水平,PI3K,p-AKT,和AKT(分别为p=0.030,p=0.024,p=0.012和p=0.025)以及PI3K和AKT的mRNA浓度(分别为p=0.002和p=0.003)显着增加,而p-ERK的平均光密度水平,ERK(分别为p=0.004和p=0.026)和ERK的mRNA浓度(p=0.001)显着降低。
    结论:我们的研究表明,irisin不仅可以改善循环胰岛素抵抗,但也可能通过增加PI3K/AKT信号的活性和减少MAPK/ERK信号的活性来改善卵巢IR。
    OBJECTIVE: To investigate the independent effects of irisin on insulin resistance (IR) in ovary of polycystic ovary syndrome (PCOS) and explore possible pathways.
    METHODS: We established PCOS medel using Poretsky L\'s method, then PCOS rats were randomly divided into model group (M) and irisin group (I), and normal rats (N) were used as the control. Then rats in the group I were injected with recombinant irisin. Then the levels of circulating fasting blood glucose (FBG), fasting insulin (FINS), homeostasis model assessment of IR (HOMA-IR) and PI3K/AKT and MAPK/ERK pathways in each group were observed, as well as the effects of irisin on the levels of circulating HOMA-IR and PI3K/AKT and MAPK/ERK pathways in ovary of PCOS rats were evaluated.
    RESULTS: Compared with normal group, levels of FBG, FINS, and HOMA-IR of model group were significantly increased (p < 0.001, p < 0.001, and p < 0.001, respectively), levels of average optical density by IHC of p-PI3K, PI3K, p-AKT, and AKT (p = 0.015, p = 0.010, p = 0.005, and p = 0.009, respectively) and levels of mRNA concentration of PI3K and AKT (p = 0.001, and p = 0.005, respectively) were decreased, while the levels of average optical density of p-ERK, ERK (p = 0.011, and p = 0.013, respectively) and level of mRNA concentration of ERK (p < 0.001) were increased in ovary. After irisin intervention, compared with model group, levels of FBG, FINS, and HOMA-IR of rats in irisin group were significantly decreased (p = 0.001, p < 0.001, and p < 0.001, respectively), levels of average optical density by IHC of p-PI3K, PI3K, p-AKT, and AKT (p = 0.030, p = 0.024, p = 0.012, and p = 0.025, respectively) and levels of mRNA concentration of PI3K and AKT (p = 0.002, and p = 0.003, respectively) were significantly increased, while the levels of average optical density of p-ERK, ERK (p = 0.004, and p = 0.026, respectively) and level of mRNA concentration of ERK (p = 0.001) were significantly decreased.
    CONCLUSIONS: Our study demonstrated that irisin could not only improve circulating insulin resistance, but may also improve ovarian IR through an increase in the activity of PI3K/AKT signaling and a decrease of MAPK/ERK signaling.

    双酚A(BPA)是一种广泛使用的化学物质,可以危害人体,包括生殖系统。由于每天通过食物接触,双酚A在体内积累,在95%的人中发现,水,和皮肤吸收。BPA可以通过干扰卵巢卵泡生成来损害女性生育能力,抑制卵泡生长,诱发闭锁,导致多囊卵巢综合征(PCOS)。PCOS是一种常见的内分泌疾病,影响许多育龄妇女。虽然目前的治疗方法可以帮助控制症状,它们不能完全预防并发症。木犀草素,一种具有药用特性的天然类黄酮,通常用于治疗代谢和炎症性疾病。因此,我们在网络药理学和分子对接研究中评估了木犀草素对PCOS的特性;保护中国仓鼠卵巢(CHO)细胞免受活性氧的抗氧化和抗炎特性,细胞损伤,和负线粒体膜电位进行评估。此外,使用斑马鱼开发了体内PCOS样模型,并使用异硫氰酸荧光素(FITC)鉴定木犀草素的定位。木犀草素保护CHO细胞免受细胞损伤,ROS,线粒体膜电位为负.木犀草素减轻了斑马鱼卵巢中的总SOD水平,诱导卵泡成熟,并改变了卵巢增殖和促炎细胞因子TNF-α和IL-1β表达的关键基因。天然植物氧化剂如木犀草素可以保护成年斑马鱼的卵泡发育和早期PCOS,以防止氧化应激和炎症。这项研究表明使用木犀草素作为植物药来缓解卵巢功能下降。
    Bisphenol-A (BPA) is a widely used chemical that can harm the human body, including the reproductive system. BPA accumulates in the body and is found in 95 % of individuals due to everyday exposure through food, water, and skin absorption. BPA can impair female fertility by interfering with ovarian folliculogenesis, inhibiting follicular growth, and inducing atresia, leading to polycystic ovary syndrome (PCOS). PCOS is a prevalent endocrine disorder that affects many reproductive-aged women. While current treatments can help manage symptoms, they do not entirely prevent complications. Luteolin, a natural flavonoid with medicinal properties, is commonly used to treat metabolic and inflammatory disorders. Therefore, we evaluated Luteolin\'s properties against PCOS in Network pharmacology and molecular docking studies; further, the antioxidant and anti-inflammatory properties in protecting the Chinese Hamster ovarian (CHO) cells from Reactive Oxygen Species, cellular damage, and negative mitochondrial membrane potential were evaluated. Additionally, an in-vivo PCOS-like model was developed using zebrafish, and the localization of Luteolin was identified using fluorescein isothiocyanate (FITC). Luteolin protected the CHO cells from cellular damage, ROS, and negative mitochondrial membrane potential. Luteolin alleviated the total SOD levels in the Zebrafish ovary, induced follicular maturation, and altered the key genes in ovarian proliferation and pro-inflammatory cytokines TNF-α and IL-1β expression. Natural Phyto-oxidants such as Luteolin may protect follicular development and early PCOS in adult zebrafish to prevent oxidative stress and inflammation. This study suggests using Luteolin as a phytomedicine to alleviate ovarian function decline.

    背景和目的:多囊卵巢综合征(PCOS)是一种广泛的内分泌疾病,影响5-18%的育龄女性。这项研究的目的是评估将低剂量的人绒毛膜促性腺激素(HCG)与柠檬酸克罗米芬(CC)结合使用以刺激诊断为CC抗性PCOS的不育女性排卵的功效。材料与方法:对300例PCOS患者进行了一项随机对照试验。将所有参与者分为两组:CC-HCG组和CC-安慰剂组。CC-HCG组的受试者给予CC(从周期的第2天开始,150mg/天,持续5天)和HCG(从周期的第7天开始,SC为200IU/天)。CC-安慰剂组的受试者给予CC和安慰剂。卵泡数>18毫米,周期取消率,子宫内膜厚度,排卵率,临床妊娠率,早期卵巢过度刺激综合征的发生都是主要研究的结果变量。结果:对来自CC-HCG组的138名个体和CC-安慰剂组的131名参与者的数据进行最终分析。与CC-安慰剂组相比,CC-HCG组的周期取消率明显较低.CC-HCG组表现出显著增加的卵泡达到>18mm,子宫内膜厚度,和排卵率。CC-HCG组的临床妊娠率较高(7.2%vs.2.3%;CC-HCG与CC-安慰剂)。调整BMI和年龄后,我们的研究结果表明,CC-HCG组中血清催乳素水平低于20(ng/mL)的个体,继发性不孕,不孕持续时间少于4年,基线LH/FSH比值低于1.5,且血清AMH水平超过4(ng/mL)的患者实现妊娠的可能性较高.在CC-安慰剂组中,对于血清AMH(<4)的患者,临床妊娠的预测更高,原发性不孕症,血清催乳素≤20(ng/mL),基线LH/FSH<1.5,不孕持续时间<4年。结论:与CC一起使用小剂量的HCG似乎是减少周期取消的有效治疗方法,提高CC耐药PCOS患者的临床妊娠率和排卵率。该试验已在ClinicalTrials.gov注册,标识符NCT02436226。
    Background and Objectives: Polycystic ovarian syndrome (PCOS) is a widespread endocrine disorder affecting 5-18% of females in their childbearing age. The aim of this study is to assess the efficacy of combining a low dosage of human chorionic gonadotropin (HCG) along with clomiphene citrate (CC) for stimulating ovulation in infertile women diagnosed with CC-resistant PCOS. Materials and Methods: A randomized controlled trial was carried out on 300 infertile CC-resistant PCOS women. All participants were assigned to two groups: the CC-HCG group and the CC-Placebo group. Subjects in the CC-HCG group were given CC (150 mg/day for 5 days starting on the 2nd day of the cycle) and HCG (200 IU/day SC starting on the 7th day of the cycle). Subjects in the CC-Placebo group were given CC and a placebo. The number of ovarian follicles > 18 mm, cycle cancellation rate, endometrial thickness, ovulation rate, clinical pregnancy rate, and occurrence of early ovarian hyper-stimulation syndrome were all outcome variables in the primary research. Results: Data from 138 individuals in the CC-HCG group and 131 participants in the CC-Placebo group were subjected to final analysis. In comparison to the CC-Placebo group, the cycle cancellation rate in the CC-HCG group was considerably lower. The CC-HCG group exhibited a substantial increase in ovarian follicles reaching > 18 mm, endometrial thickness, and ovulation rate. The clinical pregnancy rate was higher in the CC-HCG group (7.2% vs. 2.3%; CC-HCG vs. CC-Placebo). Upon adjusting for BMI and age, the findings of our study revealed that individuals in the CC-HCG group who had serum prolactin levels below 20 (ng/mL), secondary infertility, infertility duration less than 4 years, baseline LH/FSH ratios below 1.5, and serum AMH levels more than 4 (ng/mL) had a higher likelihood of achieving pregnancy. In the CC-Placebo group, there was a greater prediction of clinical pregnancy for those with serum AMH (<4), primary infertility, serum prolactin ≤ 20 (ng/mL), baseline LH/FSH < 1.5, and infertility duration < 4 years. Conclusions: The use of a small dose of HCG along with CC appeared to be an effective treatment in reducing cycle cancelation, improving the clinical pregnancy rate and ovulation rate in CC-resistant PCOS patients. The trial was registered with Clinical Trials.gov, identifier NCT02436226.

    多囊卵巢综合征(PCOS)是一种常见的内分泌疾病,会破坏生殖功能和激素平衡。它主要影响育龄妇女,并导致身体,新陈代谢,和影响生活质量的情绪挑战。在这项研究中,我们开发了一种基于机器学习的模型,用于从正常盆腔超声图像中准确识别PCOS盆腔超声图像.通过利用来自Kaggle在线平台的1,932张骨盆超声图像(GoogleLLC,山景,CA),我们能够创建一个模型,该模型能够从正常盆腔超声图像中准确检测卵巢中的多个小卵泡和PCOS盆腔超声图像的卵巢体积增加.我们开发的模型表现出了有希望的性能,实现82.6%的精度值和100%的召回值,包括100%的灵敏度和特异性。总准确度的值被证明是100%,并且F1得分被计算为0.905。从我们的研究中获得的结果是有希望的,需要进一步的验证研究来推广模型的功能,并纳入PCOS的其他诊断因素,如体格检查和实验室值.
    Polycystic ovary syndrome (PCOS) is a common endocrine disorder that disrupts reproductive function and hormonal balance. It primarily affects reproductive-aged women and leads to physical, metabolic, and emotional challenges affecting the quality of life. In this study, we develop a machine learning-based model to accurately identify PCOS pelvic ultrasound images from normal pelvic ultrasound images. By leveraging 1,932 pelvic ultrasound images from the Kaggle online platform (Google LLC, Mountain View, CA), we were able to create a model that accurately detected multiple small follicles in the ovaries and an increase in ovarian volume for PCOS pelvic ultrasound images from normal pelvic ultrasound images. Our developed model demonstrated a promising performance, achieving a precision value of 82.6% and a recall value of 100%, including a sensitivity and specificity of 100% each. The value of the overall accuracy proved to be 100% and the F1 score was calculated to be 0.905. As the results garnered from our study are promising, further validation studies are necessary to generalize the model\'s capabilities and incorporate other diagnostic factors of PCOS such as physical exams and lab values.

    这项对随机对照试验(RCTs)的系统评价和荟萃分析旨在检验我们的假设,即凉茶可以改善人体测量参数。代谢因素,多囊卵巢综合征(PCOS)女性的激素水平。在信息科学研究所进行了文献检索,Medline(PubMed),Scopus,Embase,和谷歌学者,直到2023年3月,没有语言或日期限制。分配凉茶的RCT与安慰剂治疗PCOS女性,并评估人体测量的变化,代谢指数,或激素配置文件被包括在内。纳入了6个RCT,其中235名PCOS女性(干预组119名,对照组116名)。荟萃分析表明,食用凉茶导致体重显着下降(加权平均差[WMD],-2.02千克;95%置信区间[CI],-3.25,-0.80),身体质量指数(BMI)(WMD,-0.88kg/m2;95%CI,-1.47,-0.28)和空腹血糖(FBG)(WMD,-6.47mg/dL;95%CI,-8.49,-4.45),与对照组相比。草药茶的补充也显着增加了促卵泡激素(FSH)浓度(WMD,0.56IU/L;95%CI,0.17,0.95)。同时,凉茶对腰/臀比的影响,臀围,腰围,身体脂肪,空腹胰岛素,FBG/胰岛素比值,黄体生成素,总睾酮,硫酸脱氢表雄酮不显著。草药茶可能是控制体重的潜在补充疗法,BMI,FBG,PCOS女性的FSH。建议进一步的大型随机临床试验来确认这些发现。
    This systematic review and meta-analysis of randomized controlled trials (RCTs) aimed to test our hypothesis that herbal tea may improve anthropometric parameters, metabolic factors, and hormone levels in women with polycystic ovarian syndrome (PCOS). A literature search was conducted on Information Sciences Institute, Medline (PubMed), Scopus, Embase, and Google Scholar, up to March 2023 without applying language or date restrictions. RCTs that assigned herbal tea vs. placebo on PCOS women and evaluated changes in anthropometric measurements, metabolic indices, or hormonal profiles were included. Six RCTs with 235 PCOS women (119 in the intervention and 116 in the control group) were included. Meta-analysis showed that herbal tea consumption led to significant decreases in weight (weighted mean difference [WMD], -2.02 kg; 95% confidence interval [CI], -3.25, -0.80), body mass index (BMI) (WMD, -0.88 kg/m2; 95% CI, -1.47, -0.28) and fasting blood glucose (FBG) (WMD, -6.47 mg/dL; 95% CI, -8.49, -4.45), compared to the control group. Herbal tea supplementation has also significantly increased follicle-stimulating hormone (FSH) concentration (WMD, 0.56 IU/L; 95% CI, 0.17, 0.95). Meanwhile, the effect of herbal tea on the waist/hip ratio, hip circumference, waist circumference, body fat, fasting insulin, FBG/insulin ratio, luteinizing hormone, total testosterone, and dehydroepiandrosterone sulfate was not significant. Herbal tea might be a potential supplemental therapy to manage weight, BMI, FBG, and FSH in PCOS women. Further large randomized clinical trials are recommended to affirm these findings.

    背景:多囊卵巢综合征(PCOS)是影响育龄女性的最常见的内分泌疾病。许多生物标志物可能有助于评估和管理,然而,关于它们在临床实践中的效用的证据有限。我们进行了系统评价,以确定PCOS临床管理中最有用的生物标志物。
    方法:我们搜索了MEDLINE,EMBASE,CENTRAL和HTA直到2023年8月,用于评估PCOS女性与健康对照相比的生物标志物。使用AMSTAR2工具评估方法学质量。我们报告了每种生物标志物的汇总证据,最近的置信区间为95%,最新的,和最好的质量审查。
    结果:来自3360次引用,我们纳入了75篇系统综述(88项生物标志物,191,792名妇女)。大多数评论(50/75,67%)质量中等,但报告高度异质性(66/75,88%)。我们在PCOS女性与健康对照组中发现了63种异常生物标志物。其中,22个核心生物标志物可以帮助评估PCOS的多系统影响,并告知患者管理和监测:脱氢表雄酮,催乳素,性激素结合球蛋白,总和游离的睾丸激素,抗苗勒管激素,收缩压和舒张压,c反应蛋白,纤维蛋白原,口服葡萄糖耐量试验,稳态模型评估-胰岛素抵抗指数,空腹胰岛素,总胆固醇,甘油三酯,脂蛋白(a),HDL,LDL,非HDL-胆固醇,铁蛋白,铁,
    结论:我们确定了22种评估PCOS多系统影响的核心生物标志物,并为其临床管理提供了依据。未来的研究需要建立有效的医疗保健途径。
    BACKGROUND: Polycystic ovarian syndrome (PCOS) is the commonest endocrine condition affecting reproductive age women. Many biomarkers may aid assessment and management, however evidence is limited on their utility in clinical practice. We conducted a review of systematic reviews to identify the most useful biomarkers in the clinical management of PCOS.
    METHODS: We searched MEDLINE, EMBASE, CENTRAL and HTA until August 2023 for reviews evaluating biomarkers in PCOS women compared to healthy controls. Methodological quality was assessed using the AMSTAR2 tool. We reported pooled evidence for each biomarker with 95% confidence intervals from the most recent, up-to-date, and best quality review.
    RESULTS: From 3360 citations, we included 75 systematic reviews (88 biomarkers, 191,792 women). Most reviews (50/75, 67%) were moderate quality, but reported high heterogeneity (66/75, 88%). We identified 63 abnormal biomarkers in women with PCOS versus healthy controls. Of these, 22 core biomarkers could help evaluate the multisystemic impact of PCOS and inform patient management and surveillance: dehydroepiandrosterone, prolactin, sex hormone-binding globulin, total and free testosterone, anti-Mullerian hormone, systolic and diastolic blood pressure, c-reactive protein, fibrinogen, oral glucose tolerance test, homoeostatic model assessment-insulin resistance index, fasting insulin, total cholesterol, triglycerides, lipoprotein(a), HDL, LDL, non-HDL-cholesterol, ferritin, iron, and 25-hydroxy-vitamin D.
    CONCLUSIONS: We identified 22 core biomarkers assessing the multisystemic impact of PCOS and inform its clinical management. Future research is required to establish validated healthcare pathways.

    背景:氧化应激和脂质代谢(OSLM)途径的变化在多囊卵巢综合征(PCOS)的发病和发展中起重要作用。因此,我们对OSLM相关基因进行了系统分析,以鉴定分子簇并探索有助于PCOS诊断的新生物标志物.
    方法:从GEO数据库(GSE34526、GSE95728和GSE106724)获得22名PCOS女性和14名正常女性的基因表达和临床数据。一致性聚类确定了与OSLM相关的分子簇,和WGCNA揭示了共表达模式。使用CIBERSORT算法定量评估免疫微环境。随后应用多个机器学习模型和连接图分析来探索PCOS的潜在生物标志物。和列线图用于建立多囊卵巢综合征的预测多基因模型。最后,使用TUNEL初步验证了PCOS的OSLM状态和hub基因表达谱,qRT-PCR,westernblot,和PCOS小鼠模型中的IHC测定。
    结果:鉴定了19个与OSLM相关的差异表达基因(DEGs)。根据受OSLM强烈影响的19个DEG,PCOS患者分为两个不同的组,指定为群集1和群集2。正常和两个PCOS簇中免疫细胞比例存在明显差异。随机森林显示出最好的结果,具有最小的交叉熵和最大的AUC(交叉熵:0.111AUC:0.960)。在19个OSLM相关基因中,CXCR1,ACP5,CEACAM3,S1PR4和TCF7通过贝叶斯网络鉴定,并且通过列线图(AUC:0.990CI:0.968-1.000)与PCOS疾病风险良好匹配。TUNEL分析显示PCOS小鼠卵巢颗粒细胞内DNA损伤比正常小鼠更为严重(P<0.001)。5个hub基因的RNA和蛋白表达水平在PCOS小鼠中显著升高,这与生物信息学分析的结果一致。
    结论:为PCOS患者构建了一个新的预测模型,并鉴定了5个hub基因作为潜在的生物标志物,为PCOS的临床诊断策略提供了新的见解。
    BACKGROUND: Changes in the oxidative stress and lipid metabolism (OSLM) pathways play important roles in polycystic ovarian syndrome (PCOS) pathogenesis and development. Consequently, a systematic analysis of genes related to OSLM was conducted to identify molecular clusters and explore new biomarkers that are helpful for the diagnostic of PCOS.
    METHODS: Gene expression and clinical data from 22 PCOS women and 14 normal women were obtained from the GEO database (GSE34526, GSE95728, and GSE106724). Consensus clustering identified OSLM-related molecular clusters, and WGCNA revealed co-expression patterns. The immune microenvironment was quantitatively assessed utilizing the CIBERSORT algorithm. Multiple machine learning models and connectivity map analyses were subsequently applied to explore potential biomarkers for PCOS, and nomograms were employed to develop a predictive multigene model of PCOS. Finally, the OSLM status of PCOS and the hub genes expression profiles were preliminarily verified using TUNEL, qRT‒PCR, western blot, and IHC assays in a PCOS mouse model.
    RESULTS: 19 differential expression genes (DEGs) related to OSLM were identified. Based on 19 DEGs that were strongly influenced by OSLM, PCOS patients were stratified into two distinct clusters, designated Cluster 1 and Cluster 2. Distinct differences in the immune cell proportions existed in normal and two PCOS clusters. The random forest showed the best results, with the least cross-entropy and the utmost AUC (cross-entropy: 0.111 AUC: 0.960). Among the 19 OSLM-related genes, CXCR1, ACP5, CEACAM3, S1PR4, and TCF7 were identified by a Bayesian network and had a good fit with PCOS disease risk by the nomogram (AUC: 0.990 CI: 0.968-1.000). TUNEL assays revealed more severe DNA damage within the ovarian granule cells of PCOS mice than in those of normal mice (P < 0.001). The RNA and protein expression levels of the five hub genes were significantly elevated in PCOS mice, which was consistent with the results of the bioinformatics analyses.
    CONCLUSIONS: A novel predictive model was constructed for PCOS patients and five hub genes were identified as potential biomarkers to offer novel insights into clinical diagnostic strategies for PCOS.

    细胞外囊泡(EV),富含生物活性分子如蛋白质的颗粒,核酸,和脂质,是细胞间通讯的关键介质,在各种生理和病理过程中发挥关键作用。EV已被证明与卵泡功能有关,并在两种常见的妇科疾病中发生改变:多囊卵巢综合征(PCOS)和子宫内膜异位症。卵巢卵泡是复杂的微环境,其中卵泡发生与颗粒细胞之间协调良好的相互作用,卵母细胞,和它们周围的基质细胞。最近的研究揭示了电动汽车的存在,包括外泌体和微泡,在卵泡液(FFEV)中,这构成了发育中的卵母细胞微环境的一部分。在PCOS的背景下,多方面的内分泌,生殖,和代谢紊乱,研究已经探索了这些FFEV及其货物的失调。本综述包括9项PCOS研究,两项不同的研究中通常报道了两种miRNA。miR-379和miR-200都在女性生殖中起作用。研究还证明了电动汽车作为诊断工具和治疗选择的潜在用途。子宫内膜异位症,另一种常见的妇科疾病的特征是子宫内膜样组织的异位生长,也与异常的EV信号有关。子宫内膜异位症妇女的腹膜液中的EV携带调节免疫反应并促进子宫内膜异位症病变的建立和维持的分子。来自子宫内膜异位症病变的EV,在11项综述研究中,从子宫内膜异位症患者获得的血清和腹膜液没有发现常见的生物分子.重要的是,循环电动汽车已被证明是潜在的生物标志物,也反映了病理的严重程度。了解人类卵巢卵泡内EV的相互作用可能为PCOS和子宫内膜异位症的病理生理学提供有价值的见解。针对EV介导的交流可能为这些常见妇科疾病的新型诊断和治疗方法开辟道路。更多的研究对于揭示EV参与PCOS和子宫内膜异位症卵泡发生及其失调的机制至关重要。最终导致更有效和个性化的干预措施。
    Extracellular vesicles (EVs), particles enriched in bioactive molecules like proteins, nucleic acids, and lipids, are crucial mediators of intercellular communication and play key roles in various physiological and pathological processes. EVs have been shown to be involved in ovarian follicular function and to be altered in two prevalent gynecological disorders; polycystic ovarian syndrome (PCOS) and endometriosis.Ovarian follicles are complex microenvironments where folliculogenesis takes place with well-orchestrated interactions between granulosa cells, oocytes, and their surrounding stromal cells. Recent research unveiled the presence of EVs, including exosomes and microvesicles, in the follicular fluid (FFEVs), which constitutes part of the developing oocyte\'s microenvironment. In the context of PCOS, a multifaceted endocrine, reproductive, and metabolic disorder, studies have explored the dysregulation of these FFEVs and their cargo. Nine PCOS studies were included in this review and two miRNAs were commonly reported in two different studies, miR-379 and miR-200, both known to play a role in female reproduction. Studies have also demonstrated the potential use of EVs as diagnostic tools and treatment options.Endometriosis, another prevalent gynecological disorder characterized by ectopic growth of endometrial-like tissue, has also been linked to aberrant EV signaling. EVs in the peritoneal fluid of women with endometriosis carry molecules that modulate the immune response and promote the establishment and maintenance of endometriosis lesions. EVs derived from endometriosis lesions, serum and peritoneal fluid obtained from patients with endometriosis showed no commonly reported biomolecules between the eleven reviewed studies. Importantly, circulating EVs have been shown to be potential biomarkers, also reflecting the severity of the pathology.Understanding the interplay of EVs within human ovarian follicles may provide valuable insights into the pathophysiology of both PCOS and endometriosis. Targeting EV-mediated communication may open avenues for novel diagnostic and therapeutic approaches for these common gynecological disorders. More research is essential to unravel the mechanisms underlying EV involvement in folliculogenesis and its dysregulation in PCOS and endometriosis, ultimately leading to more effective and personalized interventions.

    多囊卵巢综合征(PCOS)是一种影响育龄女性的妇科问题,伴随着一些代谢异常,从而导致肾功能和高尿酸血症的改变。由于PCOS中心脏代谢因素的高患病率,有必要预测这些女性中肾脏损伤的数量会增加。
    这篇综述旨在研究PCOS之间的潜在联系,肾功能受损,尿酸水平升高。通过阐明这种联系,我们希望为临床医生提供一种工具来对诊断为PCOS的女性的肾脏疾病风险进行分层,基于现成的肾功能参数。
    用于分析的建议在2020年系统审查和荟萃分析指南的首选报告项目中概述。随后,使用几个数据库(MEDLINE,ProQuest和EBSCOhost)在1996年至2022年之间,共纳入13项研究。血清尿酸,血清肌酐,以及估计的肾小球滤过率(eGFR)被评估为感兴趣的结果.队列质量评估,病例对照和横断面研究利用纽卡斯尔-渥太华量表进行,而ReviewManager5.4用于荟萃分析。
    PCOS女性的尿酸显着升高(平均差[MD]=0.70,95%置信区间[CI][0.45-0.95],P<0.00001)。同时,各组血清肌酐和eGFR在统计学上相似(MD=0.08,95%CI[-0.05-0.21],P=0.22和MD=3.54,95%CI[-4.53-11.61],分别为P=0.39)。
    这篇综述显示PCOS与尿酸升高显著相关。然而,eGFR和肌酐水平与健康对照组相比无显著差异.建议对PCOS患者进行常规尿酸评估,作为风险分层的简单工具。
    由于纳入研究的BMI报告有限,因此未进行体重指数(BMI)亚组分析。所有肾功能参数的定量分析也受到尿素和白蛋白的稀疏数据的限制。

    UNASSIGNED: Polycystic ovarian syndrome (PCOS) is a gynaecological problem affecting women within reproductive age, accompanied by several metabolic anomalies, thus leading to alteration in kidney function and hyperuricaemia. Due to the high prevalence of cardiometabolic factors in PCOS, there is a need to anticipate an increased number of kidney impairments amongst these women.
    UNASSIGNED: This review aims to investigate the potential link between PCOS, impaired kidney function, and elevated uric acid levels. By elucidating this association, we hope to provide clinicians with a tool to stratify the risk of kidney disease in women diagnosed with PCOS, based on readily available kidney function parameters.
    UNASSIGNED: The recommendations used for the analysis were outlined in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines. Subsequently, eligible studies were identified using several databases (MEDLINE, ProQuest and EBSCOhost) between 1996 and 2022, with a total of 13 studies included. Serum uric acid, serum creatinine, as well as estimated glomerular filtration rate (eGFR) were evaluated as the outcome of interest. Quality assessment for cohort, case-control and cross-sectional studies was conducted utilising the Newcastle-Ottawa Scale, while Review Manager 5.4 was utilised for meta-analysis.
    UNASSIGNED: Uric acid was significantly higher in women with PCOS (mean difference [MD] = 0.70, 95% confidence interval [CI] [0.45-0.95], P < 0.00001). Meanwhile, serum creatinine and eGFR were statistically similar in each group (MD = 0.08, 95% CI [-0.05-0.21], P = 0.22 and MD = 3.54, 95% CI [-4.53-11.61], P = 0.39, respectively).
    UNASSIGNED: This review showed that PCOS was significantly associated with elevated uric acid. However, no significant difference was found between eGFR and creatinine levels compared to healthy controls. Routine uric acid assessment in PCOS patients is recommended as a simple tool for risk stratification.
    UNASSIGNED: No body mass index (BMI) subgroup analysis was done due to limited BMI reporting in our included studies. Quantitative analysis of all kidney function parameters was also limited by sparse data on urea and albumin.
    UNASSIGNED: CRD42023410092 (02 April 2023).

    多囊卵巢综合征(PCOS)是一种影响育龄妇女的内分泌疾病,其特征是荷尔蒙失衡导致代谢和生殖失调。此病例报告围绕着一位30岁的丈夫和他27岁的伴侣。男性伴侣有正常精子症,女性配偶患有PCOS,根据这对夫妇的诊断评估。女性患者接受卵巢刺激专门用于辅助PCOS,然后将回收的卵母细胞在体外成熟。卵胞浆内单精子注射(ICSI)后,受精和胚胎发育成功。PCOS相关不孕症的治疗面临许多挑战,并讨论了体外成熟(IVM)及其作为有效辅助生育方法的潜力。为了优化治疗结果,结论显示了IVM和其他辅助生殖技术对不孕症的重要性.它还侧重于必要的持续研究和临床经验。通过测量血清β-人绒毛膜促性腺激素(β-hCG)水平,然后进行超声检查(USG)来确认临床妊娠,这表明胎儿的生长速度正常。
    Polycystic ovary syndrome (PCOS) is an endocrinological disorder affecting women of reproductive age, characterized by hormonal imbalance leading to metabolic and reproductive dysregulations. This case report revolves around a 30-year-old husband and his 27-year-old partner. The male partner had normozoospermia, and the female spouse had PCOS, according to the couple\'s diagnostic evaluations. The female patient received ovarian stimulation specifically to assist with PCOS, and the retrieved oocytes were then matured in vitro. After intracytoplasmic sperm injection (ICSI), fertilization and embryonic development were successful. Treatment of PCOS-related infertility presents many challenges, and in vitro maturation (IVM) and its potential as an effective assisted fertility method are discussed. To optimize treatment outcomes, the conclusion shows the importance of IVM and other assisted reproductive techniques for infertility. It also focuses on the necessary continuous research and clinical experience. Clinical pregnancy was confirmed by measuring serum beta-human chorionic gonadotropin (β-hCG) levels followed by ultrasound sonography (USG), which showed a normal growth rate of the fetus.
