摘要:
背景 分析我国省级疾病预防控制中心（简称疾控）的科技论文发表情况，可以了解疾控科研实力、优势学科、研究热点、人才建设等情况，有利于进一步优化疾控的科研建设。
目的 对2011—2020年我国省级疾控发表的中国科学引文数据库（CSCD）来源论文进行文献计量学分析并绘制可视化图谱，以了解该十年我国省级疾控的科研产出情况。
方法 2021年4月以中国知网为检索数据库，分别检索2011—2020年我国31个省级疾控（未纳入台湾省和香港、澳门特别行政区的疾控机构）以第一单位发表的CSCD来源论文，最终纳入CSCD论文5231篇。文献计量分析指标包括CSCD论文的发表量及基金资助率，CSCD论文占比，CSCD论文高载文期刊分布，以第一作者身份发表的文献数量；并采用Citespace 5.8.R1软件分别制作作者合作网络图谱、关键词共现图谱、关键词聚类信息表和关键词突现图谱。
结果 研究期间CSCD论文发表量整体呈平稳趋势，总基金资助率为61%，并呈逐年升高的趋势（由2011年的49.3%增加至2020年的68.7%）。江苏省、福建省、北京市疾控CSCD论文量排名前三。《中华流行病学杂志》《中国公共卫生》《中国人兽共患病学报》《中华预防医学杂志》《中华地方病学杂志》是排名前五的高载文期刊。CSCD论文发文量排名前三的作者（以合作作者身份统计）是河南省疾控的许汴利（110篇）、福建省疾控的严延生（72篇）、北京市疾控的王全意（71篇），研究的内容分别是寄生虫病和传染病流行病学、自然疫源性疾病及艾滋病等防治、传染病流行病学。关键词共现图谱显示艾滋病、人兽共患病、手足口病等（频次均≥90）是近十年省级疾控研究的重点方向，关键词聚类类别之间联系紧密，虽有差异，但主题集中于病毒和慢性病研究。关键词突现图谱提示随着时间的推移，研究前沿从肠道病毒、汉坦病毒、寨卡病毒等传染性疾病逐渐向食源性疾病和肿瘤、老年疾病等慢性非传染性疾病转变。
结论 近十年我国省级疾控的科技论文发文量呈现整体稳中有升的趋势，研究者和机构的重点关注方向为传染性疾病、寄生虫病等，而食源性疾病、老年疾病等则是热点前沿方向。
Abstract:Background By analyzing the publication of scientific and technological papers of the provincial centers for disease control and prevention (CDCs) in China, we can understand their scientific research strength, dominant disciplines, research hotspots, and talent development, which is conducive for further optimizing the scientific research construction of the disease control system.
Objective To conduct a bibliometric analysis and draw a visual map of the Chinese Science Citation Database (CSCD) sourced papers published by 31 provincial CDCs in China from 2011 to 2020, to understand the scientific research status of China's provincial CDC system in the past ten years.
Methods In April 2021, China National Knowledge Infrastructure was used to retrieve CSCD sourced papers published by 31 provincial CDCs (excluding Taiwan Province, Hong Kong and Macau Special Administrative Regions) in China as the primary unit from 2011 to 2020, and finally 5231 CSCD papers were included. Bibliometric analysis indicators include number of CSCD papers published and financial support rate, proportion of CSCD papers to total Chinese papers, distribution of CSCD papers published in high-volume journals, and number of papers for a specific CDC that their first authors affiliated with. Citespace 5.8.R1 software was used to draw author's cooperation network map, keyword co-occurrence map, keyword clustering information table, and keyword emergence map.
Results The number of CSCD papers published every year showed a stationary trend, and the total funding rate was 61%, showing an year-by-year upward trend (increased from 49.3% in 2011 to 68.7% in 2020). Jiangsu Province, Fujian Province, and Beijing CDCs ranked the top three in the total number of CSCD papers contributed by a specific CDC. The Chinese Journal of Epidemiology, Chinese Journal of Public Health, Chinese Journal of Zoonoses, Chinese Journal of Preventive Medicine, and Chinese Journal of Endemic Diseases were the top five high-volume journals. The top three authors of CSCD papers (counted as co-authors) were Xu Bianli of Henan Provincial Center for Disease Control and Prevention (110 papers), Yan Yansheng of Fujian Provincial Center for Disease Control and Prevention (72 papers), and Wang Quanyi of Beijing Center for Disease Prevention and Control (71 papers), and they studied the epidemiology of parasitic diseases and infectious diseases, the prevention and treatment of natural epidemic diseases and AIDS, and the epidemiology of infectious diseases, respectively. The keyword co-occurrence map showed that AIDS, zoonotic diseases, hand-foot-mouth disease, etc. (frequency ≥90) were the key research directions of provincial CDCs in the past ten years. The keyword clustering categories were closely related, although there were subtle differences, the topics focused on virus and chronic disease research. The keyword emergence results suggested that the frontiers of research had gradually shifted from infectious diseases such as enterovirus, hantavirus, and Zika virus to food-borne diseases and chronic non-communicable diseases such as tumors and senile diseases over time.
Conclusion The number of papers issued by the provincial CDCs in China in the past ten years has shown an overall steady and rising trend. The leading themes of researchers and institutions are infectious diseases, parasitic diseases, etc., while food-borne diseases and elderly diseases are the hot frontiers.
