Metabonomics 的最初定义是就生物系统对生理和病理刺激以及基因改变的代谢应答的定量测定(“the quantitative measurement of the multi-parametric metabolic response of living systems to pathophysiological stimuli or geneticmodifications”). 我们认为这个定义现在可以更广泛地表述为:代谢组学是关于定量描述生物内源性代谢物质的整体及其对内因和外因变化应答规律的科学 (“Metabonomics is the branch of s展开更多

Emerging evidence has begun to illustrate TCM as an area of important medical rediscoveries. This review article briefly introduced the concept, significance, and technology of network pharmacology based on network biology and systems biology. It focused on the theoretical system and potential prospect of TCM network applied in TCM research and development including predicting new drug targets, action mechanism, new drug discovery; evaluating pharmacodynamics, pharmacokinetics, safety, toxicology, quality control, and bioinformatics of drugs. We also discussed the opportunities and challenges in the development and application of network pharmacology in the modernization of TCM research.展开更多
