基于Citespace的国内外隐匿性高血压相关研究可视化分析

A Citespace-based visualization analysis on studies related to masked hypertension(MH)at home and abroad

目的分析国内外有关隐蔽性高血压研究领域的发展状况与关注焦点,了解该领域的研究基础和前沿,为广大学者全面和深层次探究该领域提供参考。方法以中国知网(CNKI)与Web of Science(WOS)核心合集数据库作为文献来源,采用“隐匿性高血压”作为研究主题,检索截止2020年8月11日CNKI和WOS上已发表的所有相关文献,筛选后按发表年度、作者、机构、期刊、关键词等进行整理,通过Citespace软件分别进行合作网络分析、共现分析和共被引分析。结果最终纳入中文文献191篇,英文文献815篇。国内外发文量总体趋势均呈波动上升趋势,但发展步伐不一。美国、日本、意大利是该领域高产出和领头国家。作者以Jan A.Staessen产出最多,专注于不同人群的MH发病和决定因素以及MH合并症、进展与预后;贡献较大的作者及团队还有以Takayoshi Ohkubo、Kazuomi Kario所在的日本东北大学与Giuseppe Mancia所在的意大利比克卡大学。国内主要研究人物和团队代表是王继光教授所在的上海交通大学附属瑞金医院,但国内MH研究机构较为零散,缺乏内部合作。被引频次最高的期刊、作者、文献分别是J HYPERTENS、Obrien E、Obrien E(2013)。国内外热点关键词早期均主要集中在隐匿性高血压、动态血压、白大衣性高血压、靶器官损害,之后中文文献关键词移向家庭血压监测、夜间血压、正常高值血压、左室肥厚和降压治疗,形成3大聚类;而英文文献则转向年龄、儿童、男性、睡眠呼吸暂停综合征、糖尿病、慢性肾病、血管僵硬、子痫、并发症、生存率、预后价值、预防、血压变异性、隐匿未控制高血压、夜间血压、亚型等上,形成9大聚类。总体国外较国内研究更为全面、系统,值得国内借鉴和学习。结论通过对国内外隐匿性高血压相关研究进行分析,直观地展现了其整体概况和发展趋势,初步揭示了重要作者、国家和研究机构并挖掘剖析了当前该领域内研究热点和前沿,以便后期学习和深入。

Objective To analyze the development status and research focus of masked hypertension(MH)at home and abroad,understand both the research foundation and frontier in this field,and provide reference for scholars in this area.Methods Taken CNKI and Web of Science(WOS)databases as literature resources and MH as research topic,all relative literature published on CNKI and WOS were retrieved before Aug.11,2020.The literature were sorted according to their published years,authors,institutions,journals and keywords after screening.The cooperation network analysis,co-occurrence analysis and co-citation analysis were conducted by using Citespace software.Results A total of 191 Chinese documents and 815 English documents were included.The overall trend of publication volume showed fluctuated increase at home and abroad.The United States,Japan and Italy were leading countries with more production in this field.Jan A.Staessen had the most production,mainly concentrating on incidence and determining factors of MH,and MH complications,progress and prognosis.Other important authors and teams that also contributed a lot in this field were Takayoshi Ohkubo and Kazuomi Kario from Tohoku University in Japan,and Giuseppe Mancia from University of Milano Bicocca in Italy.The main domestic team representative for MH was Ruijin Hospital affiliated to Shanghai Jiaotong University where Professor Wang Jiguang was located,but domestic MH research institutions were scattered and lacked internal cooperation.The most frequently cited journals,authors,and articles were J Hypertens,Obrien E,Obrien(2013)respectively.The popular keywords in the early stage at home and abroad were mainly concentrated on MH,ambulatory blood pressure,white coat hypertension(WCH)and target organ damage,and later the keywords in Chinese literature moved to family blood pressure monitoring,night blood pressure,high-normal blood pressure,left ventricle hypertrophy and anti-hypertensive treatment,which formed 3 clusters.And the English literature turned to focus on age,children,male,sleep apnea syndrome,diabetes,chronic kidney disease,vascular stiffness,eclampsia,complications,survival rate,prognostic value,prevention,blood pressure variability,uncontrolled MH,nighttime blood pressure and subtypes,which formed 9 clusters.In general,researches in this field abroad were more comprehensive and systematic than domestic researches,which offered some reference and enlightenments to domestic researchers.Conclusion By analyzing both domestic and foreign studies on MH,the overall situation and development trend as well as important authors,countries and research institutions were intuitively presented and preliminarily revealed.Moreover,current hotspots and frontiers in this field are found to facilitate further integral and in-depth study regarding MH.
