中文摘要: 中医临床辨证选药须遵循疗寒以热药、疗热以寒药的原则,但是目前中药成分研究西药化现象严重,药性理论的临床指导作用弱化。如何客观准确评价中药成分的药性,对于开发符合中医临床特点的中药创新药物具有重要意义。 课题组在前期973计划项目中药药性理论相关基础问题研究中,发现中药寒热药性与中药成分分子结构相关,提出中药性-构关系研究构想,拟从化学信息和生物效应两方面探索构建中药成分寒热药性综合评价体系,为客观、准确评价中药成分药物的寒热药性提供科学依据:(1)以中药及其成分的化学信息为研究对象,通过关联规则挖掘、结构相似性计算和药效团模型构建等方法,建立中药成分药性识别模型;(2)以药性相关的生物信息为研究对象,通过研究中药药性-靶点-信号通路之间的关联关系,构建寒热药性生物评价网络模块;并设计斑马鱼温敏行为轨迹监测仪和细胞受体配体结合实验,建立中药微量成分寒热药性效应评价体系。

英文摘要: The herbal choice on TCM clinic must follow the principle of use herbal with hot nature to treat cold syndrome and use herbal with cold nature to treat hot syndromes. But Chinese herbal medicinal ingredients were used on clinic according to pharmacodynamics, and avoiding the guiding function of the natural theory of TCM. The cold and hot nature precisely evaluation of ingredients from Chinese medicine is important for the development of original new drug under guide of the theory of TCM. We found the cold and hot nature of herbals related to the structure of its ingredients in the earlier research on natural basic theory of traditional Chinese drug supported by 973 program and proposed the theory of the Relationship between Nature and Structure. This project is to establish a comprehensive evaluation system of cold and hot natural of ingredients from chemoinformation and biology effects: (1) Use association rules mining methods, chemical similarity calculation and Pharmacophore model construction method to analyze chemoinformation of Chinese medicine and it's gradients to build natural assess model; (2) Study the association of nature-targets-signal path to build the biological evaluation network module of cold and hot nature; Designed zebrafish temperature sensitive track monitor cell receptor ligand binding assay to build a system asses the cold and hot effect of microconstituents from Chinese medicine.
