卵巢储备(OR)和生育力在女性医疗保健中至关重要。编码OR和生育力的临床方法依赖于组合测试,这不能作为一个多功能平台,从特定的生物液中获得有限的信息。在这里,使用粒子辅助激光解吸/电离质谱仪(Paldi-MS)对卵泡中的卵泡液(MFFF)进行代谢指纹分析,以编码OR和生育力。PALDI-MS可以实现高效的MFFF,表现出快速(≈30 S)、高灵敏度(≈60fmol)和理想的重复性(变异系数<15%)。进一步,机器学习被应用于诊断减少的OR(曲线下面积为0.929),并通过一次Paldi-MS测试识别高质量的卵/胚胎(p&lt;0.05)。同时,来自MFFF的代谢生物标志物也被确定,这些生物标志物也决定了抽样卵泡的卵母细胞/胚胎质量(p&lt;0.05),用于临床生育预测。这一方法在女性医疗保健领域提供了一个强大的平台,不仅限于OR和生育。本工作利用粒子辅助激光解吸电离质谱仪(PALDI-MS),通过对卵泡液代谢指纹图谱(MFFF)的机器学习,开发了一个编码卵巢储备(OR)和生育力的平台。这样的MFFF可能有助于通过一次Paldi-MS测试来诊断OR减少和识别高质量的卵母细胞/胚胎(p&lt;0.05)。这项工作将对妇科疾病的代谢分析起到推动作用。
Ovarian reserve (OR) and fertility are critical in women's healthcare. Clinical methods for encoding OR and fertility rely on the combination of tests, which cannot serve as a multi‐functional platform with limited information from specific biofluids. Herein, metabolic fingerprinting of follicular fluid (MFFF) from follicles is performed, using particle‐assisted laser desorption/ionization mass spectrometry (PALDI‐MS) to encode OR and fertility. PALDI‐MS allows efficient MFFF, showing fast speed (≈30 s), high sensitivity (≈60 fmol), and desirable reproducibility (coefficients of variation <15%). Further, machine learning of MFFF is applied to diagnose diminished OR (area under the curve of 0.929) and identify high‐quality oocytes/embryos (p < 0.05) by a single PALDI‐MS test. Meanwhile, metabolic biomarkers from MFFF are identified, which also determine oocyte/embryo quality (p < 0.05) from the sampling follicles toward fertility prediction in clinics. This approach offers a powerful platform in women's healthcare, not limited to OR and fertility. This work develops a platform to encode ovarian reserve (OR) and fertility through machine learning of metabolic fingerprinting of follicular fluid (MFFF), using particle‐assisted laser desorption/ionization mass spectrometry (PALDI‐MS). Such MFFF may help to diagnose diminished OR and identify high‐quality oocytes/embryos (p < 0.05) by a single PALDI‐MS test. This work would advance the metabolic analysis of gynecological diseases.
