基于CiteSpace的中医药防治肺结节知识图谱可视化分析

Visualized analysis of knowledge map for traditional Chinese medicine prevention and treatment of pulmonary nodules based on CiteSpace

该文基于知识图谱分析中医药防治肺结节(pulmonary nodules,PN)的研究现状和发展趋势,为未来研究方向提供参考和建议。检索中国知网(CNKI)、万方(Wanfang)、维普(VIP)和中国生物医学文献服务系统(SinoMed)从建库至2021年12月31日发表的中医药防治PN的相关文献,并根据纳入和排除标准进行文献筛选。筛选完成后根据年发文量绘制折线图,分析研究热度。利用CiteSpace 5.8.R1绘制中医药防治PN的知识图谱,对研究作者、机构、内容及热点进行深入分析。最终纳入122篇文献,折线图显示年发文量从2018年开始呈上升趋势。知识图谱分析显示,张晓梅是发文量最多的作者,主要研究团队有4个;北京中医药大学及其附属医院为领头机构;疾病、病机、治疗为主要研究内容;“数据挖掘”“中医证候”为前沿热点。近年来中医药防治PN的研究热度持续上升,未来应加强各团队及机构间的跨地区交流合作,开展更多中医药防治PN的真实世界研究和基础研究,获得高级别循证证据,并明确方剂作用机制。

This study aims to analyze the current status and development trend of the prevention and treatment of pulmonary nodules(PN)with traditional Chinese medicine(TCM)based on knowledge map and to provide both references and suggestions for future research directions.CNKI,Wanfang,VIP,and SinoMed were searched for relevant papers from the inception to December 31,2021.Eligible articles were included according to the inclusion and exclusion criteria.The line chart was drawn based on the annual publication volume of articles,and the research interests of this field were learned.The knowledge maps of prevention and treatment of PN with TCM were drawn in CiteSpace 5.8.R1,and the authors,institutions,contents,and hotspots were analyzed.A total of 122 articles were included and the line chart demonstrated that the annual publication volume has been rising since 2018.According to the knowledge maps,the most prolific author was ZHANG Xiao-mei and there were four main research teams.Beijing University of Chinese Medicine and its affiliated hospitals were in a leading position in this field.The main research contents were disease,pathogenesis,and treatment,and the hotspots were data mining and TCM syndrome.The research on prevention and treatment of PN with TCM has become an increasing field of interest in recent years.In the future,the cross-regional cooperation and communication between research teams and institutions should be strengthened for more real-world studies and basic studies about the prevention and treatment of PN with TCM,so that the high-level evidence can be obtained and the underlying mechanisms of TCM formulae in the treatment of PN be clarified.
