目的回溯并勾勒2010年-2020年全球脑卒中领域研究的主题演化历程与时空分布规律。方法从PubMed数据库中获取2010年-2020年脑卒中相关文献，利用R 4.1.2的pubmedR软件包批量抓取文献基本信息，通过quanteda软件包构建语料库，使用结构主体模型进行分析，并运用ggplot2软件包进行国家或地区合作网络分析。结果全球脑卒中研究2010年-2013年为快速增长期，增长率为11.94%～17.60%；2014年-2018年为增长平缓期，增长率为3%～4%左右；2019年-2020年再次快速增长，增长率为12.81%、17.96%。中国大陆地区在2012年、2020年增长率分别为102.99%、43.85%，在全球两个阶段的高速增长期中均做出了较大贡献。基于文献摘要文本，共归纳出11个主题类别，其中“临床研究”与“卒中康复”占较大比重，合计热度值为46.66%。我国近年研究热点主要集中在“分子遗传病学”与“动物实验”。结论全球脑卒中研究热度持续增长，主题类别逐渐丰富。我国需进一步加强脑卒中前端预防和后端康复研究，优化防治策略。

ObjectiveTo retrospectively outline the evolution and spatial-temporal distribution of the theme of global stroke research from 2010 to 2020.MethodsLiterature related to stroke from 2010 to 2020 was obtained from PubMed database, basic information of literature was captured in batches by pubmedR package (R 4.1.2), corpus was constructed by quanteda package, and structural subject model was used for analysis. The ggplot2 package was used to analyze national or regional cooperation networks.ResultsGlobal stroke research showed a rapid growth period from 2010 to 2013, with a growth rate of 11.94% to 17.60%. The growth period from 2014 to 2018 was flat, with a growth rate of about 3%~4%. From 2019 to 2020, it grew rapidly again, with growth rates of 12.81% and 17.96%. With a growth rate of 102.99 percent in 2012 and 43.85 percent in 2020,the mainland area in China has contributed significantly to the two periods of rapid global growth. Based on the abstract text of literature, a total of 11 subject categories were summarized, among which "clinical research" and "stroke rehabilitation" accounted for a large proportion, with a total heat value of 46.66%.In the recent years, the focus of research in China has been on "molecular epidemiology" and "animal experiments".Conclusion The global research on stroke continues to increase in popularity, and the subject categories are gradually enriched. We need to further strengthen the research on front-end prevention and back-end rehabilitation of stroke and optimize prevention and treatment strategies.
