基于CiteSpace及VOSviewer的脑出血手术治疗相关研究现状及趋势的可视化分析

Visualization analysis of the current status and trend of researches related to cerebral hemorrhage surgery based on CiteSpace and VOSviewer

目的通过对近10年脑出血手术治疗相关文献进行可视化分析,总结并探讨脑出血手术治疗相关领域研究现状、热点及趋势。方法检索并筛选中国知网和Web of Science数据库2014年1月1日至2024年4月1日脑出血手术治疗相关中、英文文献,采用CiteSpace、VOSviewer等软件对发表文献数量、作者、国家、机构等进行可视化分析,并结合关键词聚类网络分析图谱、关键词突现强度和关键词时间线图谱内容分析脑出血手术治疗相关领域的研究热点和趋势。结果(1)经检索与筛选,共纳入脑出血手术相关中、英文文献3456篇,其中中文文献2173篇,英文文献1283篇。2014年至2021年,脑出血手术相关中文文献年发表数量高于英文文献,但自2016年起,中文文献发表数量开始有所下降。英文文献发表数量总体呈现增长趋势。(2)英文文献共检索出6367位作者,其中以Mocco J、Hanley Daniel F、Ziai Wendy C、You Chao、Tang Zhouping等研究者为代表的合作网络最为突出;中文文献共检索出6522名作者,其中以王丽琨、蔡强、库洪彬、张山、朱遂强等作者为代表的合作网络较为突出。(3)对发表英文文献的国家进行分析,结果显示,共31个国家参与脑出血手术治疗相关研究,其中中国发表文献数量位居首位(505篇),美国与德国分别位列第2位(330篇)和第3位(106篇);中心性排名前3的国家依次为美国(0.32)、中国(0.16)和加拿大(0.11)。英文文献发表量排名前3的机构分别为约翰斯·霍普金斯大学(51篇)、俄亥俄州立大学(39篇)和哈佛大学(38篇);国内四川大学(32篇)、华中科技大学(30篇)、首都医科大学(27篇)等机构发表多篇英文文献;武汉大学人民医院(15篇)、贵州医科大学附属医院(13篇)、延安大学附属医院(13篇)等发表了多篇中文文献。英文文献研究机构间合作较为密切;中文文献研究者多以所在医疗单位建立研究团队,团队间合作相对较少。(4)脑出血手术治疗相关研究主要围绕手术方式、并发症及围手术期综合治疗展开。研究热点包括高血压脑出血、微创手术技术及围手术期的管理和治疗,其中“神经内镜”是中文文献最近一次突现的关键词,中心性较高,突现强度最大;“随机试验”是英文文献突现强度最大的关键词。人工智能与微创技术相融合、脑出血手术的治疗和管理策略优化、危险因素分析和影像学价值探讨可能是未来的研究趋势。结论近10年,脑出血手术治疗相关研究的文献发表数量处于稳定发展阶段,研究内容涉及手术技术、诊疗、评估、管理等方面。核心作者群所在的科研团队为发表文献的主力。手术技术优化、并发症管理、多中心大样本临床试验、人工智能与微创技术融合等可能是该领域研究热点和趋势。

Objective To summarize and explore the current state,hotspots,and trends in the field of surgical treatment for intracerebral hemorrhage(ICH)over the past decade through a bibliometric and visualization analysis of relevant literature.Methods Relevant Chinese and English literature on the surgical treatment of ICH,published from January 1,2014 to April 1,2024,was retrieved and screened from CNKI and Web of Science databases.Visualization analysis was conducted using CiteSpace,VOSviewer,and other software to analyze the number of published papers,authors,countries,institutions,etc.Social network analysis diagrams of authors,keyword clustering network analysis diagrams,keyword burst strength,and keyword timeline maps were also utilized.Results(1)A total of 3456 relevant papers were included,with 2173 in Chinese and 1283 in English.From 2014 to 2021,the annual number of Chinese publications on ICH surgery was higher than that of English publications,but the number of Chinese publications began to decline from 2016.The number of English publications showed an overall increasing trend.(2)A total of 6367 authors were identified from the English literature,with notable collaboration networks led by researchers such as Mocco J,Hanley DF,Ziai WC,You C,and Tang ZP.The Chinese literature included 6522 authors,with prominent collaboration networks led by Wang LK,Cai Q,Ku HB,Zhang S,and Zhu SQ.(3)Analysis of the countries involved in the English literature showed that 31 countries participated in research on ICH surgery,with China leading in the number of publications(505),followed by the United States(330)and Germany(106).The top three countries in centrality were the United States(0.32),China(0.16),and Canada(0.11).The top three institutions in English literature publications were Johns Hopkins University(51 papers),Ohio State University(39 papers),and Harvard University(38 papers).In China,Sichuan University(32 papers),Huazhong University of Science and Technology(30 papers),and Capital Medical University(27 papers)had multiple English publications;Wuhan University People′s Hospital(15 papers),Affiliated Hospital of Guizhou Medical University(13 papers),and Affiliated Hospital of Yan′an University(13 papers)had multiple Chinese publications.There was close collaboration among research institutions in the English literature,whereas Chinese researchers often established research teams within their medical units with relatively less collaboration between teams.(4)Research on ICH surgery primarily focused on surgical methods,complications,and comprehensive perioperative treatment.Research hotspots included hypertensive ICH,minimally invasive surgical techniques,and perioperative management and treatment.“neuroendoscopy”was the most recent emergent keyword in Chinese literature with high centrality and the strongest burst strength,while“randomized trial”had the highest burst strength in English literature.Research trends included the integration of artificial intelligence with minimally invasive techniques to optimize ICH surgery management and treatment strategies,analysis of risk factors,and evaluation of imaging value.Conclusions Over the past decade,the overall publication volume on the surgical treatment of ICH has been in a stable development phase,with research directions covering surgical techniques,diagnosis and treatment,evaluation,and management.Core research teams led by key authors were the main contributors to the publications.Future research hotspots and trends in ICH surgery may include the optimization of surgical techniques,complication management,large-scale multicenter clinical trials and integration of artificial intelligence with minimally invasive techniques.
