摘要
目的分析中国在体外肺膜氧合(Extracorporeal Membrane Oxygenation,ECMO)领域的基础研究实力。方法在Web of Science数据库中检索ECMO相关的科技论文,基于论文数量、被引频次、高被引论文数量以及高频词聚类,分析中国在该领域的研究规模、影响力及研究热点。结果 1970年至今,全球ECMO相关科技论文共计8822篇,近十年复合增长率达11.4%。美国的论文数量和影响力均居全球绝对领先地位,中国论文数量(592篇vs.3975篇)仅为美国的七分之一,总被引频次(7360次vs.95021次)和高被引论文数量(3篇vs.42篇)均不足美国的十分之一,篇均被引频次(12.4次/篇vs.23.9次/篇)仅为美国的一半,单看中国大陆地区(论文数量277篇,总被引频次2133次,篇均被引频次7.7次/篇)则与美国差距更为明显。中国仅台湾大学一家机构的论文数量进入全球前20位,中国前10位机构的平均总被引频次(658次)、篇均被引频次(11.8次/篇)和高被引论文数量(0.3篇)均远低于全球前20位机构的均值(分别为7476次、34.2次/篇、6.8篇)。中国仅有的少量研究主要集中在"体外心肺复苏"和"急性呼吸窘迫综合征的机械通气治疗"两个方向。结论我国在ECMO领域基础研究规模小,学术影响力弱,研究实力与美国相比差距明显,目前仅有的少量研究主要集中在应急救治方面,很少涉及先天缺陷和心肺移植手术的支持治疗。
Objective To analyze the basic research competitiveness of China in the field of extracorporeal membrane oxygenation(ECMO).Methods Scientific papers on ECMO were retrieved from the Web of Science database,based on which bibliometric analysis was conducted.The scale and impact of research were analyzed based on the number of papers,citations and highly cited papers,and hotspots were displayed by clustering analysis of high-frequency words.Results From 1970 to the present,8822 scientific papers on ECMO had been published,with a compound annual growth rate of 11.4%in recent 10 years.The scale and impact of research in the United States were in absolute global leadership.The number of papers published by China was only oneseventh of that by United States(592 vs.3975).For China,the total number of citations(7360 vs.95021)and the number of highly cited papers(3 papers vs.42 papers)were less than one-tenth of that for the United States,and the average citations per paper(12.4 vs.23.9)was only half of that for the United States.Looking at China's Mainland alone(277 papers,2133 citations in total,7.7 citations per paper),the gap with the United States was even more obvious.Among the institutions in China,only Taiwan University ranked top 20 in the number of papers.The means for the total citations(658),average citations per paper(11.8)and the number of highly cited papers(0.3)for the top 10 Chinese institutions were far lower than those for the top 20 institutions in the world(7476,34.2,and 6.8).The studies of China mainly focus on“cardiopulmonary resuscitation”and“mechanical ventilation therapy for acute respiratory distress syndrome”.Conclusion In the field of ECMO,China has conducted a small scale of basic research and produced relatively weak academic impact,with a significant gap compared with the United States;the researches by Chinese scholars mainly focus on emergency treatment,with few involve the supportive treatment of congenital defects and heart/lung transplantation.
