Visualization analysis of research hotspots and trends of poststroke depression in the field of traditional Chinese medicine based on CiteSpace

目的基于CiteSpace软件探讨中医药领域中风后抑郁症研究热点和趋势。方法通过中国知网数据库将2002年1月至2021年4月收录的中医药领域中风后抑郁症的有关文献作为研究对象,分别以发文趋势、作者合作情况、机构、关键词等进行分析,并绘制相应的知识图谱,最终将可视化分析结果结合人工检索进行深入讨论。结果共纳入文献1767篇,年发文量总体呈曲线上升的趋势,并通过计量分析找到了文献高产机构和代表性研究者及其团队。研究热点及趋势为中医情志护理、针灸及分子生物学等,中医药领域数据挖掘技术的应用也是目前研究的主流。结论图谱初步直观地展示了中医药领域的发展趋势,揭示了研究热点,较为直观地展示了中医对中风后抑郁症的研究概况,对研究热点及前沿形成了大致认识,为确定研究方向提供参考。

Objective To explore the hotspots and trends of poststroke depression in the field of traditional Chinese medicine(TCM)based on CiteSpace software.Methods The literatures on poststroke depression in the field of the TCM collected from January 2002 to April 2021 was selected as the research subjects by CNKI database.The trend of the published articles,the cooperation status of authors,the institutions,the key words were analyzed respectively and the corresponding knowledge maps were drawn.Finally,visualization analysis results combined with manual retrieval were discussed in depth.Results A total of 1767 articles were included,and the annual number of published articles showed an upward trend.Through quantitative analysis,high-yield literature institutions and representative researchers and their teams were found.Research hotspots and trends were TCM emotional nursing,acupuncture and molecular biology,etc.The application of data mining technology in the field of TCM was also the mainstream of current research.Conclusion The maps initially and visually show the development trend of TCM,and reveal the research hotspots.They show the research overview of TCM on poststroke depression more intuitively,and form a general understanding of research hotspots and frontiers,and provide reference for determining the research direction.
