Objective: To analyze the characteristics and citations of articles in National Medical Journal of China (NMJC) during 2016, and to discuss the academic level and quality of the journal. Methods: All the literature published in NMJC during 2016 were retrieved through the Chinese Medical Citation index, and the citation frequency data in China's core journals of science and technology from January 2017 to December 2018 was obtained through Institute of Scientific and Technical Information of China. The citation status of articles published in NMJC was statistically analyzed by the method of literature metrology. The main indicators included the citation rate of articles published in each year, the citation frequency of all articles, the citation status of individual papers and authors, the regional and high-yield institution distribution of cited authors, and the main citation journals. Results: In 2016, a total of 962 articles were published in 22 columns of NMJC. The total number of published pages was 3 940, and the average number of articles was 4.09 pages. A total of 28 key topics have been published. The total citation was 2 077 times, with 2.16 times per paper. Among them, 322 papers were not cited, accounting for 33.47%. The maximum citation frequency of a single paper was 66 times. There were good citations in the columns of Guidelines, Epidemiology, New technology and methods, Clinical research and Editorial. Oncology, neurology/psychiatry, imaging/ultrasound/radiology, respiratory medicine and orthopedics accounted for a large part [40.43% (389 articles)]. Articles in neurosurgery, respiratory medicine, preventive medicine and gastrointestinal surgery were all cited with high frequency (all ≥2.75 times/article). A total of 483(50.21%) articles had obtained fund support, and the rate (68.12%) of them cited was slightly higher than that of articles without fund support (64.93%). A total of 23 articles were cited ≥10 times, and 16 first authors were cited ≥10 times. In addation, 26 corresponding authors were cited ≥10 times and 10 institutions were cited more than 15 times. The authors of the cited papers were distributed in 29 provinces (autonomous regions, municipalities directly under the central government), and there were more articles and higher total citation frequency in Beijing, Shanghai, Jiangsu and Tianjin. From 2017 to 2018, papers published in NMJC were cited 2 077 times by a total of 490 journals. Conclusions: The guidelines published in NMJC is highly cited. The editorial department should adjust the column setting timely, strengthen the planning of key topic selection and the solicitation and publicity of excellent papers, and further improve the influence of the magazine.
目的： 分析2016年《中华医学杂志》的载文特征和被引情况。 方法： 通过中国生物医学期刊引文数据库检索2016年发表在《中华医学杂志》的所有文献信息，通过中国科学技术信息研究所获得上述文献于2017年1月—2018年12月被中国科技核心期刊引用的相关数据。主要分析指标包括2016年载文被引率、篇均被引频次、单篇论文被引情况、高被引作者、被引作者的地区和高产机构分布等。 结果： 2016年《中华医学杂志》主要22个栏目共载文962篇（共3 940页，篇均4.09页）；共刊载28个重点号专题。总被引2 077次，篇均被引2.16次，零被引论文占比为33.47%（322篇）；单篇论文最高被引频次为66次；标准与规范、流行病学调查、新技术新方法、临床研究、述评等栏目篇均被引频次较高；肿瘤、神经内科/精神科、影像/超声/放射、呼吸内科和骨科等学科的载文量较多[40.43%（389篇）]，神经外科、呼吸内科、预防医学以及胃肠外科4个学科的文章篇均被引频次较高（均≥2.75次/篇）。共有50.21%的文章获得基金资助（483/962），有基金资助的文章的被引率（68.12%）略高于无基金资助的文章（64.93%）。共有23篇文章被引≥10次，16名第一作者被引≥10次，26名通信作者被引≥10次，所发表文章的总被引频次超过15次的有10家单位。被引论文的第一作者分布在29个省（自治区、直辖市），北京、上海、江苏、天津的发文数和总被引频次均较高。2017—2018年，中国科技核心期刊中有490种期刊引用了本刊发表的论文共计2 077次。 结论： 《中华医学杂志》指南、共识类文章被引频次较高，编辑部应适时调整栏目设置，加强重点号选题策划及优秀论文的组稿和宣传力度，进一步提高杂志的影响力。.
