SCIE收录的胃肠肝病学期刊发表的中国内地作者的肝脏疾病研究文献计量分析

A bibliometric analysis of liver disease research articles published by Chinese mainland authors in Gastroenterology&Hepatology journals indexed in Science Citation Index Expanded

目的检索2016年—2020年中国(不含港澳台地区)作者在SCIE(Science Citation Index Expanded)数据库收录的胃肠肝病学期刊上发表的肝脏疾病相关论文,对其题录与引文数据进行统计分析,以了解中国学者在肝脏疾病研究领域的贡献及其影响力。方法文献计量学分析数据来源于SCIE数据库与JCR(Journal Citation Report)。在SCIE数据库中检索出版年为2016年—2020年发表在JCR胃肠肝病学期刊上,题名或摘要中包含Liver、Hepatocellular、Hepatitis、Cirrhosis或Hepatic,出版物类型为Article的期刊文章,排除临床指南,并筛选通信作者单位含有中国(不含港澳台地区)机构的记录。使用R package bibliometrix计算纳入文献在2016年—2020年被中国作者和全球作者在胃肠肝病学期刊发表的肝脏疾病研究引用的频次。使用R package DescTools对构成比的变化进行Cochran-Armitage趋势检验。结果2016年—2020年Q1区胃肠肝病学期刊上,中国作者发表的肝脏疾病研究占比为9.5%。近年,中国作者在高水平胃肠肝病学期刊(Q1区)上发表的肝脏疾病研究数量不断增加,占全球研究的比例从6.0%不断上升至12.2%(P<0.001)。中国作者在Q1区胃肠肝病学期刊发表的肝脏疾病研究获国自然基金资助的比例达79.7%,5年间,各分区胃肠肝病学期刊上发表的中国作者的研究获国自然基金资助的比例均无明显变化。比较被中国与全球作者在胃肠肝病学期刊上发表的肝脏疾病研究引用频次,显示了中国作者发表的在国内和国际学界均具有较高影响的肝脏疾病研究。结论近年,中国作者在SCIE收录、高影响力的胃肠肝病学期刊发表的肝脏疾病研究数量不断增加,其中大部分研究获国自然基金资助。中国学者在胃肠肝病学期刊上发表的肝脏疾病论文被国内学界和国际学界广泛认可。

Objective To investigate the articles on liver diseases published by authors from China(excluding Hong Kong,Macao,and Taiwan regions)in Gastroenterology&Hepatology journals indexed in Science Citation Index Expanded(SCIE)in 2016-2020,to analyze the bibliographic and citation data of these articles,and to understand the contribution and impact of Chinese scholars in the field of liver disease research in recent years.Methods The data for bibliometric analysis came from the SCIE database and Journal Citation Reports(JCR).The SCIE database was searched for the journal articles published in JCR Gastroenterology&Hepatology journals in 2016-2020,with a title or abstract containing“Liver”,“Hepatocellular”,“Hepatitis”,“Cirrhosis”,or“Hepatic”and a publication type of Article.Clinical guidelines were excluded,and the records with the corresponding author’s affiliation containing institutions in China(excluding Hong Kong,Macao,and Taiwan regions)were screened out.R package bibliometrix was used to calculate the frequency of citations of included articles by liver disease studies published by Chinese and global authors in the Gastroenterology&Hepatology journals in 2016-2020,and R package DescTools was used to perform the Cochran-Armitage trend test to observe the change in composition ratio.Results In the Q1 Gastroenterology&Hepatology journals in 2016-2020,liver disease studies published by Chinese authors accounted for 9.5%.In recent years,the proportion of liver disease studies published by Chinese authors in Q1 Gastroenterology&Hepatology journals continues to increase from 6.0%to 12.2%(P<0.001).Among the liver disease studies published by Chinese authors in Q1 Gastroenterology&Hepatology journals,79.7%were funded by National Natural Science Foundation of China,and there was no significant change in the proportion of studies funded by National Natural Science Foundation of China and published by Chinese authors in each partition of Gastroenterology&Hepatology journals in 2016-2020.The frequency of citations of included articles by liver disease studies published by Chinese and global authors in the Gastroenterology&Hepatology journals showed that liver disease studies published by Chinese authors had a high impact in both domestic and international academic communities.Conclusion In recent years,there has been a constant increase in the number of liver disease studies published by Chinese authors in high-impact Gastroenterology&Hepatology journals indexed in SCIE,and most of these studies have been funded by National Natural Science Foundation of China.The liver disease studies published by Chinese authors in Gastroenterology&Hepatology journals have been widely recognized by domestic and international academic communities.
