2015—2019年中国学者发表结核病科技论文情况分析

目的 分析2015—2019年间中国学者发表的结核病科技论文概况。方法 在中国生物医学文献服务系统(SinoMed)中检索结核病相关中文文献,共检索到29223篇,再通过中国知网引文数据库(CNKI)查询发表论文的被引情况;在PubMed分面检索与聚类分析系统(PubMedPlus)中检索结核病相关英文文献,共检索到3963篇,再通过济南泉方本地PubMed检索系统查询发表论文的被引情况;文献检索时限均为2015—2019年。对检索到的文章数量、发表期刊分布、第一作者所在机构及机构所在地区、被引频次等进行统计分析。结果 2015—2019年,中国学者在中文期刊上发表的结核病相关论文数量共计为29223篇,各年度分别为7155篇(24.48%)、6318篇(21.62%)、5499篇(18.82%)、5176篇(17.71%)、5075篇(17.37%),呈逐年下降趋势,年均下降率为8.23%;在英文期刊上发表的论文数量共计为3963篇,各年度分别为710篇(17.92%)、697篇(17.59%)、775篇(19.56%)、810篇(20.44%)、971篇(24.50%),呈逐年上升趋势,年均增长率为8.14%,且在全球结核病相关论文中的占比[各年度分别为10.02%(710/7083)、9.62%(697/7243)、10.80%(775/7173)、11.39%(810/7112)、12.73%(971/7628)]也呈逐年上升趋势。在论文发表数量前10位的中英文期刊中,仅2种中文期刊属于科技核心期刊,其中《中国防痨杂志》发表的文章数量最多(1260篇),占全部中文期刊发表论文的4.31% (1260/29223);而英文期刊全部属于《科学引文索引》(SCI)收录期刊。中文期刊刊文第一作者所在机构发表篇数较多的主要为结核病专科医院,排名前10位占比8/10,以广东、北京和江苏地区作者发表论文篇数较多(22.23%,6495/29223);而英文期刊发表论文篇数较多的机构则多为综合性医院和研究机构,排名前10位占比8/10,以北京、上海和广东发表论文篇数较多(60.64%,2403/3963),较中文期刊发表论文地区不均衡性分布更加明显(χ²=2621.70,P<0.01),其中,首都医科大学附属北京胸科医院发表的文章篇数在中英文期刊中均居榜首(分别为801篇和203篇)。发表于中文期刊的论文被引率为68.11%(19903/29223),总被引频次为78179,但被引超过30次的论文仅11篇,而英文期刊中有179篇。结论 2015—2019年,中国学者在结核病领域内发表的结核病科技论文数量较多,但中文论文数量呈逐年下降趋势;同时,存在不同地区、机构间的科研产出分布明显不均衡的问题,且中文期刊的论文被引频次较低。

The analysis of papers on tuberculosis published by Chinese scholars from 2015 to 2019

Objective To analyze the situation of scientific and technological papers in the field of tuberculosis published by Chinese scholars from 2015 to 2019.Methods All of 29223 Chinese papers related to tuberculosis were retrieved using SinoMed and the citation related information of published papers was searched using CNKI;3963 English papers related to tuberculosis were retrieved using PubMedPlus and the citation related information of published papers was searched using Jinan Quanfang Local PubMed retrieval system;retrieval time was from 2015 to 2019.The number of retrieved papers,the distribution of published journals,the organizations and regions of the first author,and the citation frequency were statistically analyzed.Results From 2015 to 2019,the total number of papers related to tuberculosis published by Chinese scholars in Chinese journals were 29223,which were 7155(24.48%)in 2015,6318(21.62%)in 2016,5499(18.82%)in 2017,5176(17.71%)in 2018,and 5075(17.37%)in 2019 respectively,showing a downward trend by year,with an average annual decline rate of8.23%.The total number of papers published in English journals were 3963,with 710(17.92%),697(17.59%),775(19.56%),810(20.44%),and 971(24.50%)in each year,showing an increasing trend with an average annual growth rate of 8.14%.The proportion of papers published by Chinese authors in English journals(10.02%(710/7083),9.62%(697/7243),10.80%(775/7173),11.39%(810/7112),12.73%(971/7628))also showed an increasing trend year by year;only 2 of the top 10 Chinese journals were sci-tech core journals,and among them,Chinese Journal of Antituberculosis published the largest number of papers(1260),accounting for 4.31%(1260/29223)of all papers published in Chinese journals.All the top 10 English journals were SCI journals.More first authors in Chinese journal were from tuberculosis specialized hospitals(top 10:8/10),and the institutions were located in Guangdong,Beijing,and Jiangsu(22.23%,6495/29223).However,those with more articles published in English journals were general hospitals and research institutions(top10:8/10),while the institutions were located in Beijing,Shanghai and Guangdong(60.64%,2403/3936),and the imbalance of regional distribution was more obvious compared with the papers published in Chinese journals(χ²=2621.70,P<0.01).The number of papers published by Beijing Chest hospital,Capital Medical University ranked first in both Chinese and English journals(801 and 203,respectively).The citation rate of papers published in Chinese journals was 68.11%(19903/29223),and total citation frequency was 78179.However,only 11 papers were cited more than 30 times,compared with 179 papers in English journals.Conclusion From 2015 to 2019,a large number of papers had been published in the field of tuberculosis by Chinese scholars,but the number of papers published in Chinese journals showed a downward trend year by year;at the same time,the distribution of scientific research output in different regions and institutions was obviously unbalanced,and the citation frequency of papers in Chinese journals was low.
