The causal link between NETs and sepsis progression has been extensively validated. However, few articles have utilized bibliometric methods to analyze research in this field. Therefore, this paper analyzes the research hotspots and trends in NETs and sepsis over the past two decades from a bibliometric perspective, aiming to provide new insights into the fundamentals and research in this field. Methods: We collected publications related to neutrophil extracellular traps (NETs) in the field of sepsis from 2004 to 2024 from the Web of Science Core Collection. Publications were limited to articles and reviews, and the language was restricted to English. VOSviewer and COOC software were used to conduct bibliometric and knowledge map analysis of research collaboration networks, journals, cited references, and keywords in this field. Results: From 2004 to 2024, the Web of Science Core Collection included 720 articles on NETs and sepsis research, including 452 articles and 226 reviews. Since 2022, the number of articles in this field has rapidly increased. The United States and China are the primary contributors in this field. Articles on this topic have been published in 294 academic journals. The author with the most publications is Liaw Patricia C., and Frontiers in Immunology is the most cited journal. In addition to “sepsis” and “neutrophil extracellular traps,” high-frequency terms in the keyword co-occurrence network analysis include inflammation, neutrophils, platelets, thrombosis, Covid-19, infection, innate immunity, and septic shock. An analysis of keyword trends using the burst test indicates that thrombosis and ARDS are currently at the forefront of research in this field. ARDS is currently a hot topic regarding the related roles and potential mechanisms of NETs and sepsis in this field. Conclusion: This study provides a bibliometric analysis and visualization of key research areas in sepsis and NETs over the past 20 years. The results indicate that thrombosis and ARDS are currently hot topics regarding the related roles and potential mechanisms of NETs and sepsis in this field.展开更多

文摘本文利用CiteSpace软件对我国数字经济赋能农业的研究进行了可视化分析,数据来源于CNKI中国知网数据库期刊和博硕论文,对我国2018至今数字经济赋能农业相关文献,运用CiteSpace进行格式转化并对其发文量、作者合作、关键词共现网络、关键词演进、关键词突现等进行可视化分析。结果:本研究共纳入共获取有效文献1324篇。关键词聚类分析表明,研究热点从2019年的“大数据”演变为2021年的“数字金融”,再到2024年的“数字农业”,反映了政策倾向和研究领域的实际状况。整体来看,数字技术在农业领域的应用持续受到学术界的关注,特别是在数字金融和大数据方面,显示出较强的研究活力和政策支持。In this paper, CiteSpace software is used to carry out a visual analysis of the research on digital economy empowered agriculture in China. The data comes from CNKI database journals and Bosh papers, and the relevant literature on digital economy empowered agriculture in China from 2018 to now is analyzed. CiteSpace was used for format conversion and visual analysis of the number of published documents, author cooperation, keyword co-occurrence network, keyword evolution, keyword emergence, etc. Results: A total of 1324 valid literatures were included in this study. Keyword cluster analysis shows that the research focus has evolved from “big data” in 2019 to “digital finance” in 2021 and then to “digital agriculture” in 2024, reflecting the policy orientation and the actual situation of the research field. Overall, the application of digital technology in the field of agriculture continues to receive attention from the academic community, especially in digital finance and big data, showing strong research vitality and policy support.

文摘The evaluation of social practice outcomes is a critical component of the social practice mechanisms in colleges and universities,serving as a core index to assess the effectiveness of practice activities and the quality of student training.This paper employs CiteSpace to analyze references,keyword co-occurrence maps,time zone maps,and time diagrams,identifying key research hotspots in social practice evaluation systems domestically and internationally.These hotspots include the construction of evaluation indicators,evaluation pathways,and methods.Additionally,this study compares and summarizes the evolution of social practice evaluation systems across regions.It highlights that foreign social practice evaluation systems are characterized by diverse interpretative paradigms,an emphasis on students’self-reflection during the evaluation process,and more robust theoretical foundations.These findings provide valuable insights for domestic colleges and universities seeking to build social practice evaluation systems with relevant content and effective results.
文摘基于文献可视化探析中医药近年发展,从文献中研究其现状和热点,本研究则使用CiteSpace对“中医药”和(AND)“发展”两个主题相关文章进行可视化,并使用Excel辅助制作表格,总共呈现的知识图谱有:文献年度发文趋势图、高频关键词表格、关键词共现图、机构合作网络图、关键词聚类统计表格、关键词时序演进图、关键词突现图。本研究依托于中医药近年政策发展的背景下探索中医药发展现状和热点导向,对中医药未来发展进行讨论,提出赓续中医药文化、完善中医药医疗服务体系、促进中医药与现代科学融合的未来展望,期望为中医药的赓续和发展有所助益。Based on literature visualization, this study explores the recent development of traditional Chinese medicine (TCM) by examining its current status and hotspots through relevant articles on the themes of “traditional Chinese medicine” and “development” using CiteSpace for visualization.
