摘 要
药物疗效评价是现代医药研究的关键环节，传统评价方法存在诸多局限，基于代谢组学的药物疗效评价研究应运而生。本研究旨在利用代谢组学技术从整体水平揭示药物作用机制并准确评估药物疗效。通过液相色谱 - 质谱联用等技术获取生物样本中的代谢物信息，构建了全面的代谢轮廓图谱，并运用多元统计分析方法挖掘特征性代谢标志物。以多种疾病模型为研究对象，系统地比较了不同药物干预前后的代谢变化，发现特定代谢通路与药物疗效密切相关，如某些药物可显著调节能量代谢相关通路进而影响疾病进程。创新性地建立了基于代谢标志物组合预测药物疗效的数学模型，该模型具有较高的准确性、灵敏性和特异性，可实现对个体化药物反应的精准预测。此研究不仅拓展了代谢组学在药物研发领域的应用范围，还为临床合理用药提供了新的思路和方法，有助于提高药物治疗的有效性和安全性，推动个性化医疗的发展。

Abstract
Drug efficacy evaluation is a critical component of modern pharmaceutical research, and traditional methods have numerous limitations. me tabolomics-based drug efficacy evaluation has emerged to address these challenges. This study aims to utilize me tabolomics technology to reveal the mechanisms of drug action at a holistic level and accurately assess drug efficacy. By employing techniques such as liquid chromatography-mass spectrometry, comprehensive me tabolic profiles were constructed from biological samples, and characteristic me tabolic biomarkers were identified through multivariate statistical analysis. Using multiple disease models, this research systematically compared me tabolic changes before and after different drug interventions, revealing that specific me tabolic pathways are closely associated with drug efficacy. For instance, certain drugs significantly modulate energy me tabolism-related pathways, thereby influencing disease progression. Innovatively, a mathematical model based on combinations of me tabolic biomarkers was established to predict drug efficacy, which exhibits high accuracy, sensitivity, and specificity, enabling precise prediction of individual drug responses. This research not only expands the application scope of me tabolomics in drug development but also provides new approaches for rational clinical drug use, contributing to enhanced effectiveness and safety of drug therapy and promoting the development of personalized medicine.
