基于引文空间的中医药治疗经皮冠状动脉介入术后患者的可视化分析

CiteSpace-based visualization analysis of traditional Chinese medicine treatment for patients after receiving percutaneous coronary intervention

目的应用可视化分析方法,挖掘经皮冠状动脉介入术后中医药治疗的主要研究内容、研究前沿、作者及机构合作网络,为中医药治疗经皮冠状动脉介入术后患者的诊治和研究提供参考。方法在中国知网、维普和万方数据库中检索有关经皮冠状动脉介入治疗(percutaneous coronary intervention,PCI)术后中医药治疗的文献,将其导入至NoteExpress软件中进行筛选与数据清洗,利用引文空间软件对关键词、作者、机构等进行分析。结果共获得了1708篇文献,其中2020年发文量最多,为137篇;核心作者数量占总发文人数的4.37%,暂未形成核心作者群;辽宁是发文量最多的地区,各地之间尚未形成有效的协作网络;聚类分析得到25个聚类,448个关键节点和1266条连线,主要的聚类结果为冠心病、急性冠脉综合征、急性心肌梗死、再狭窄等;突现分析得出24个突现词,包括中医辨证、参芍口服液、心脏康复等。结论中医药治疗PCI术后主要的研究内容包括中医辨证、病因病机、临床试验等,再狭窄等术后病理现象为本领域之研究难点,焦虑、双心医学、心脏康复为当前研究热点。中医药在促进PCI术后心功能的恢复、降低术后再狭窄等事件的发生率,改善焦虑和抑郁等方面具有确切疗效。

Objective By using CiteSpace-based visualization analysis to investigate the main research contents,research frontiers,author cooperation network and institutional cooperation network of traditional Chinese medicine(TCM)treatment for patients after receiving percutaneous coronary intervention(PCI)so as to provide reference for the TCM diagnosis,treatment and research of patients after receiving PCI.Methods A computerized retrieval of academic papers concerning TCM treatment of patients after receiving PCI from CNKI,VIP and Wanfang databases was conducted.The retrieved literature materials were input into NoteExpress software to make the literature screening and the data cleaning.CiteSpace software was used to analyze the keywords,authors,institutions,etc.Results A total of 1708 articles were obtained;the number of published articles in 2020 was the largest,which was up to 137 articles.The core authors accounted for 4.37%of the total number of authors who had written articles,but no core author group had been formed yet.Liaoning province of China was the region where the number of published articles was the largest,and there was no effective collaboration network between different areas.The cluster analysis yielded 25 clusters,448 key nodes and 1266 lines.The main cluster results were coronary heart disease,acute coronary syndrome,acute myocardial infarction,restenosis,etc.The analysis of emergent words(i.e.the suddenly increased frequency of a certain key word in a certain period)yielded 24 emergent words,including syndrome differentiation of TCM,ginseng peony oral liquid,cardiac rehabilitation,etc.Conclusion The main research contents of TCM treatment for patients after PCI include syndrome differentiation of TCM,etiology and pathogenesis,clinical trials,etc.Postoperative pathological phenomena such as restenosis are the research difficulties in this field,and anxiety,dual-mind TCM,and cardiac rehabilitation are the current research hotspots.TCM has definite efficacy in promoting the recovery of cardiac function after PCI,in reducing the incidence of postoperative events such as restenosis,and in improving anxiety and depression.
