基于数据挖掘的中药复方治疗中晚期非小细胞肺癌用药规律研究

Study on Medication Regularity of Compound Herbal Formulae for Treating Advanced Non-small Lung Cancer Based on Data Mining

目的探索中药复方治疗中晚期非小细胞肺癌(NSCLC)的用药规律。方法检索中国生物医学文献数据库(CBM)、中国知识资源总库(CNKI)、中国学术期刊数据库(万方数据)公开发表的文献中治疗中晚期NSCLC的中药复方,建立相应数据库,采用频数分析、聚类分析、关联规则等方法对复方进行数据挖掘,对主要药物、药对(组)规律进行分析。结果在治疗中晚期NSCLC的107首中药复方中,涉及193味药物,使用频次为1298次,其中使用频次≥9次的药物有42种;42种药物的性味、归经分析发现,四气中以寒性最多(409频次),五味中以甘味最多(627频次),归经中以肺经为最多(546频次)。作为主要药物进行聚类分析,分为补阴药、清热药、补气药、补血药、活血药、止血药、化痰药、降气药、敛肺药共9类;经关联规则分析,共得药对规则26条,药组规则18条,主要为益气药、养阴药与清热药的配伍组合。结论治疗中晚期NSCLC中药复方用药以寒、平为主,甘、苦药居多,归经以肺、脾、胃经为主,治法以益气、养阴、解毒为主。

Objective To study the medication regularity of compound herbal formulae in treating patients with advanced non-small lung cancer （NSCLC）. Methods Compound herbal formulae published on journals for the treatment of NSCLC were searched and collected from CBM, CNKI, and Wanfang Data for database establishment. Frequency analysis, cluster analysis, and association rule analysis were used for data mining, and regularity of main Chinese medicinal herbs and herbal pairs （combinations） were investigated. Results There were 107 compound herbal formulae （involving 193 Chinese medicinal herbs and 1298 frequency） for NSCLC. 42 Chinese medicinal herbs were used for more than 9 times. Cluster analysis on the tastes and properties of the 42 Chinese medicinal herbs found that, among the four qi, cold showed the highest frequency （409）;among the five tastes, sweet showed the highest frequency （627）;among the meridians, lung meridian showed the highest frequency （546）. Cluster analysis divided main Chinese medicinal herbs into 9 types, including yin-nourishing herbs, heat-clearing herbs, qi-tonifying herbs, blood-enriching herbs, blood circulation activating herbs, hemostasis herbs, phlegm-reducing herbs, qi-descending herbs, lung-astringing herbs. Associate rule analysis obtained 26 rules for Chinese medicinal herbal pairs, 18 rules for Chinese medicinal herbal combination, most of which were combinations for tonifying qi, nourishing yin, and clearing heat. Conclusion Chinese compound herbal formulae for the treatment of NSCLC mainly use Chinese medicinal herbs with properties of cold and mildness, with the tastes of sweet and bitter, with meridians of lung, spleen, and stomach, with the treatment of tonifying qi, nourishing yin, and detoxication.
