采用CiteSpace可视化分析近20年功能磁共振运用于脑卒中领域的国内发文量现状

CiteSpace Visualized Analysis of Domestic Literature on Application of Functional Magnetic Resonance in Field of Stroke in Past 20 Years

目的:应用CiteSpace软件对国内近20年功能磁共振(f MRI)运用于脑卒中领域的研究现状及热点进行可视化分析。方法:以中国知网(CNKI)数据库为数据来源,利用CiteSpace软件对国内近20年脑卒中与fMRI相关的研究进行作者、研究机构及关键词分析。结果:纳入644篇文献,国内运用fMRI在脑卒中领域的研究从2002年开始兴起,呈波浪式上升,至今仍是研究热点。发文量最高的作者是孙莉敏(上海复旦大学)。研究机构以高校及其附属医院为主,范围较局限,缺乏机构、区域之间更广泛的交流合作。fMRI在卒中研究中的热点领域主要集中在针刺治疗卒中的研究、卒中后康复的研究、卒中后偏瘫、失语的治疗及作用机制的研究。fMRI数据分析方法如功能连接、功能重组、低频振幅为热门使用的方法。除去主题词外较活跃的高频被引关键词聚类为功能连接、综述、运动想象、头针、高压氧等。结论:脑卒中与fMRI相关的知识图谱研究规律发现其中涉及不同针刺方法治疗、卒中后康复、卒中后遗症治疗及作用机制、功能磁共振数据分析方法等多个方面。

Objective:CiteSpace software was used to visually analyze the research status and hotspots related to stroke and functional magnetic resonance imaging(fMRI) in the past 20 years.Methods:Using China National Knowledge Infrastructure(CNKI) database as the data source,the authors,research institutions,and keywords of studies related to stroke and fMRI in the past 20 years were analyzed by CiteSpace software.Results:A total of 644 literatures were included.Domestic studies on fMRI in the field of stroke began to appear in 2002,showing a rising wave,and is still a research hotspot today.The most published author was Sun Li-min(Fudan University of Shanghai).The research institutions were mainly universities and affiliated hospitals,which had limitations and lack broader communication and cooperation between institutions and regions.The hot areas of fMRI in stroke research mainly focused on acupuncture treatment of stroke,rehabilitation after stroke,and the treatment and mechanism of hemiplegia and aphasia after stroke.fMRI data analysis methods such as functional connection,functional reorganization,and low-frequency amplitude are frequently used.In addition to subject words,the most active clusters of frequently cited keywords are functional connection,review,motor imagery,acupuncture,and hyperbaric oxygen.Conclusion:The knowledge graph of fMRI and stroke shows that it involves different acupuncture treatment,rehabilitation after stroke,treatment and mechanism of stroke sequelae,fMRI data analysis,and multiple other aspects.
