中医药疗效评价研究热点的双向聚类计量学分析

Bi-clustering Bibliometric Analysis on Research Hotspots of Efficacy Evaluation in Traditional Chinese Medicine

目的:通过双向聚类的文献计量学分析方法,探索近年来中医药疗效评价研究热点。方法:以中医药疗效评价为主题词,检索在中国知网数据库从建库开始至2018年12月31日期间所发表文献,利用书目信息共现挖掘系统提取的关键词,并使用gCLUTO软件进行双向聚类分析。结果:中国知网数据库共收录中医药疗效评价相关文献2513篇,最早发表于1986年。自2002年始发表文献数量呈指数级增长,近10年(2009—2018年)累计发表文献1789篇,占该领域所有文献量的71.2%。聚类分析结果显示,研究热点主要集中在中医药疗效评价方法学、评价指标选择、以及在具体疾病领域的应用,以中医药疗效评价的方法学及其评价指标选择为核心热点。结论:近年来中医药疗效评价的文献数量呈指数级增长。随着对中医药疗效评价方法学研究的深入,可最终制定出适合中医药发展的疗效评价标准体系促进中医药全面发展。

Objective:To explore research hotspots of efficacy evaluation in traditional Chinese medicine(TCM)in recent years through bi-clustering bibliometric analysis.Methods:“Efficacy evaluation”and“traditional Chinese medicine”were used as subject words to search CNKI database for literatures published from the beginning of the database to December 31st,2018.Then key words were extracted by Bibliography Item Co-occurrence Mining System.Bi-clustering analysis was carried out by gCLUTO software.Results:A total of 2513 literatures on efficacy evaluation in TCM were found in CNKI database,and the earliest one was published in 1986.Since 2002,the number of published literatures showed an exponential increase.A total of 1789 literatures were published in the past 10 years(2009—2018),accounting for 71.2%of all the literatures in this field.Results of clustering analysis showed that the research hotspots mainly focused on methodology of TCM efficacy evaluation,selection of evaluation indicators,as well as its application in specific disease fields.Among them,the methodology of TCM efficacy evaluation and the selection of evaluation indicators were the core hotspots.Conclusion:The number of literatures on evaluation of efficacy in TCM has increased exponentially in recent years.With the in-depth study on the methodology of evaluating the efficacy in TCM,efficacy evaluation standard system suitable for TCM development will be put forward to promote comprehensive development of TCM.
