摘要
针对传统方剂配伍规律分析方法的不足,提出一种面向复杂网络的新型中药(traditional Chinese medicine,TCM)方剂配伍规律挖掘算法。根据中药方剂特性并结合点式互信息构建TCM网络模型,结合TCM网络的小世界特性提出TCM网络的局部适应度模型,分析TCM网络的特性并挖掘TCM网络中配伍关系紧密、相似度较大的药物群。以4 000余首经典方剂作为实验对象,验证了所提方法具有较好的有效性,与经典LFM(local fitness measure)算法对比,平均模块度值提高了0.05,为中药方剂的配伍规律进行探索及新药研发提供了新思路。
Aiming to overcome the drawbacks of traditional Chinese medicine(TCM)prescription analysis,this paper proposes a new complex networks-based TCM prescription mining algorithm,which creates the TCM networks by combining the characteristics of prescriptions and point mutual information.This paper also proposes a new local fitness model of TCM networks by integrating the feature of small world,which can analyze the characteristics of TCM networks and discover the closely linked and similar herb groups.Extensive experiments are conducted on more than4000prescriptions to evaluate the effectiveness of the proposed algorithm.Compared with the LFM(local fitness measure)algorithm,the results show that the average modularity can be improved by0.05.The proposed algorithm can be applied to explore the compatibility of prescriptions and provide new ideas for the research and development of new medicines.
