<b>Comparing the Metabolomic Landscape of Polycystic Ovary Syndrome within Urban and Rural Environments</b>

<b>Background</b>Polycystic Ovary Syndrome (PCOS) affects up to 10% of women of reproductive age, characterized by hormonal imbalances and metabolic complications. Environmental factors potentially influence the biochemical expression of this condition. This study aims to examine the impact of urban versus rural environments on metabolite profiles in women with PCOS.<b>Methods</b>Thirty women aged between 18 and 40, diagnosed with PCOS according to the Rotterdam 2003 criteria, were recruited, with 16 from urban settings and 14 from rural settings. Serum samples were analyzed using liquid chromatography-tandem mass spectrometry. Principal component analysis and orthogonal partial least squares discriminant analysis were performed to identify metabolic patterns and differences between the two groups.<b>Results</b>This study reveals significant differences in metabolite profiles between women with PCOS from various environmental backgrounds. Rural participants exhibit higher levels of lipid-related metabolites, especially Palmitone, indicating specific dietary influences. Urban participants show distinct changes in carbohydrate and nucleotide metabolism pathways, likely due to processed food consumption. Multivariate analyses demonstrate a clear separation between the groups, emphasizing the environmental impact on PCOS expression.<b>Conclusions</b>This research highlights potential environment-related biomarkers for PCOS, emphasizing the importance of developing tailored treatment strategies considering environmental factors. The distinct metabolic profiles observed between urban and rural women provide new insights into the syndrome's complex mechanisms, indicating that environmental influences play a critical role in its biochemical expression and may affect its clinical manifestations.

【背景】多囊卵巢综合征（Polycystic Ovary Syndrome, PCOS）在育龄女性中的患病率可达10%，以激素失衡与代谢并发症为主要特征。环境因素或可影响该疾病的生化表型。本研究旨在探究城乡环境差异对多囊卵巢综合征女性代谢谱的影响。【方法】本研究招募了30名年龄在18至40岁之间、符合2003年鹿特丹诊断标准的多囊卵巢综合征患者，其中城市环境组16人，农村环境组14人。采用液相色谱-串联质谱法对血清样本进行检测分析。通过主成分分析与正交偏最小二乘判别分析，识别两组受试者的代谢模式与组间差异。【结果】本研究发现，不同环境背景下的多囊卵巢综合征女性其代谢谱存在显著差异。农村组受试者的脂质相关代谢物水平更高，尤其是棕榈酮（Palmitone），提示其饮食结构存在特异性影响。城市组受试者则表现出碳水化合物与核苷酸代谢通路的显著改变，这可能与加工食品的摄入有关。多变量分析显示两组样本呈现明显的聚类分离，进一步证实了环境因素对多囊卵巢综合征表型的影响。【结论】本研究揭示了潜在的多囊卵巢综合征环境相关生物标志物，强调了在制定个体化治疗策略时需纳入环境因素考量的重要性。城乡女性间观察到的差异化代谢谱，为解析该综合征的复杂发病机制提供了新视角，提示环境因素在其生化表型表达中发挥关键作用，并可能影响其临床表型。

背景概述

该数据集聚焦于多囊卵巢综合征（PCOS）在城市和农村环境中的代谢组学比较研究，通过分析30名PCOS患者的血清样本，揭示了两组在代谢物谱上的显著差异：农村参与者表现出更高的脂质相关代谢物水平，而城市参与者则显示出碳水化合物和核苷酸代谢通路的独特变化。研究结果强调了环境因素对PCOS生化表达的关键影响，为开发基于环境的个性化治疗策略提供了新见解。
