基于科学知识图谱的证候演变规律研究可视化分析

Visual Analysis of Syndrome Evolution Based on Mapping Knowledge Domains

目的:利用可视化工具CiteSpace和VOSviewer分析证候演变规律研究的现状、未来发展趋势及存在问题,为后续研究提供可行性建议。方法:检索中国知网(CNKI)、万方数据库(WanFang Data)、维普(VIP)自建库至2022年3月关于证候演变规律的相关文献,应用VOSviewer 1.6.17和CiteSpace 5.3.R4软件绘制科学知识图谱,对发文年代、作者、机构以及关键词进行可视化分析。结果:共纳入817篇文献,该领域自1980年起步并逐步得到重视,形成以王颖辉、傅强、黄燕、孙喜灵为代表的4个作者集群,作者间的合作较为紧密。主要研究机构以北京中医药大学为首,区域间的合作紧密,但缺乏跨地区合作。关键词聚类分析共形成9个具有代表性的聚类标签,高频关键词有证候要素、冠心病、围手术期、2型糖尿病、聚类分析等,突现词以“证候要素”最为显著。结论:通过可视化技术直观分析证候演变规律领域的研究概况,揭示了高质量临床研究、理论探索、动物实验及生物标志物研究是未来研究方向。

Objective:Visual tools CiteSpace and VOSviewer were used to analyze the present status,future development trend,and existing problems of the research on evolution of TCM syndromes,and to provide feasible suggestions for subsequent research.Methods:Literatures of TCM syndrome evolution were retrieved from CNKI,WanFang Data,and VIP self-built databases up to March 2022,and scientific knowledge maps were mapped by VOSviewer 1.6.17 and CiteSpace 5.3.R4.for Visual analysis of the publication year,author,organization,and keywords.Results:A total of 817 articles were included in the study.This field was gradually gained attention from 1980,there were four author clusters represented by Wang Yinghui,Fu Qiang,Huang Yan,and Sun Xiling,and the cooperation between the authors was relatively close.The main research institutions were led by Beijing University of Traditional Chinese Medicine,with close inter-regional cooperation,with a little of cross-regional cooperation.A total of 9 representative cluster labels were formed by keyword cluster analysis.The high-frequency Keywords included syndrome factors,coronary heart disease,perioperative period,type 2 diabetes mellitus,cluster analysis,etc.The emergent word was "syndrome factors".Conclusion:The research situation in the field of syndrome evolution was analyzed intuitively by visualization technology,which revealed that high-quality clinical research,theoretical exploration,animal experiments and biomarker research are the future research directions.
