Recent years have witnessed some controversial viewpoints in clinical and basic research, which exert a great influence on the research trend of acute pancreatitis (AP). We aimed to analyze the literature on AP by metrology, co-occurrence, co-citation, and visualization, and to explore the research status and trend in this field in the past 5 years.
The relevant literature collected in Web of Science Core Collection (WoSCC) database from 2015 to 2019 was searched using "acute pancreatitis" as the title word, and the co-occurrence analysis of authors, institutions, countries, and keywords was carried out by using CiteSpace V. On this basis, the keywords were clustered and analyzed by using VOSviewer 1.6.8 and Carrot 2 software, and a visual map was drawn.
A total of 2035 articles were included, with an average annual volume of more than 400. The high-yield authors were mainly Chinese, among which Li WQ was the most prominent. Most of these articles were from universities and institutions of high-yielding countries including China, the United States, and India. The main sources of journals were professional journals, among which Pancreas and Pancreatology have the most literature collection volume (both over 100), including clinical and basic research. Among the funds, the National Natural Science Foundation of China and NIH were the main 2 sponsors. Disciplinary attributes involved multiple subjects such as gastroenterology, internal medicine, and surgery. Keyword co-occurrence and clustering results showed that the classification, mortality, and risk factors of AP were still more concerned, and the research trend of this disease was the molecular mechanism of the severity of AP.
CiteSpace can be used to analyze the knowledge graph of AP, to show its development status initially and intuitively, and to provide a reference for topic content and its further development.
近年来临床和基础研究中出现了一些有争议的观点，对急性胰腺炎（AP）的研究趋势产生了很大影响。我们旨在通过计量学、共现分析、共被引分析和可视化分析急性胰腺炎相关文献，以探讨该领域过去5年的研究现状和趋势。
以Web of Science核心合集（WoSCC）数据库为数据源，检索2015年至2019年以“急性胰腺炎”为标题词的相关文献，运用CiteSpace V对作者、机构、国家和关键词进行共现分析。在此基础上，利用VOSviewer 1.6.8和Carrot 2软件对关键词进行聚类分析并绘制可视化图谱。
共纳入2035篇文章，年均发文量400余篇。高产作者主要来自中国，其中李WQ最为突出。这些文章大多来自包括中国、美国和印度在内的高产国家的高校和机构。期刊来源主要为专业期刊，其中《胰腺》和《胰腺病学》文献收录量最多（均超过100篇），涵盖临床和基础研究。在基金方面，中国国家自然科学基金和美国国立卫生研究院是主要的两个资助方。学科属性涉及胃肠病学、内科和外科等多个学科。关键词共现和聚类结果显示，AP的分类、死亡率和危险因素仍备受关注，该病的研究趋势是AP严重程度的分子机制。
CiteSpace可用于分析AP的知识图谱，初步直观地展示其发展现状，为主题内容及其进一步发展提供参考。
