BACKGROUND: Bronchopulmonary dysplasia (BPD) is a severe chronic lung disease primarily affecting premature infants, often resulting from prolonged mechanical ventilation and oxygen therapy. Oxidative stress plays a critical role in the pathogenesis of BPD, contributing to lung injury, inflammation, and impaired lung development. Despite extensive research, there is a need to systematically map out the research trends and hotspots in this field to inform future studies and therapeutic strategies. METHODS: This study utilized bibliometric and visualized analysis to explore global research trends and hotspots on oxidative stress and BPD from 2004 to 2024. A comprehensive literature search was conducted in the Web of Science Core Collection, focusing on publications related to oxidative stress and BPD. Tools such as VOSviewer, Citespace, and the R package Bibliometrix were employed to analyze Coauthorship, co-citation, and keyword co-occurrence networks, as well as to identify emerging research fronts and influential studies. RESULTS: The analysis identified 597 relevant publications, showing a steady increase in research output over the 20-year period, with a significant surge in the last decade. The United States led in research contributions, followed by China and Germany, with notable collaborations among these countries. Coauthorship analysis highlighted key research institutions, such as Harvard University and the University of California, as central nodes in the research network. Thematic clustering revealed five major research areas: antioxidant mechanisms, inflammation, molecular pathways, lung development, and therapeutic interventions. The keyword co-occurrence analysis showed a shift in research focus over time. Early studies concentrated on basic pathophysiological mechanisms, while recent research has increasingly focused on advanced molecular techniques, such as gene expression and targeted therapies. Notably, the study identified emerging research hotspots, including the role of extracellular vesicles and cellular senescence in BPD, as well as the potential therapeutic applications of antioxidants like superoxide dismutase mimetics. CONCLUSION: This bibliometric study provides a comprehensive overview of the research landscape on oxidative stress and BPD, identifying key trends, influential authors, and emerging research topics. The findings underscore the importance of continued research in this field, particularly in translating basic scientific insights into clinical applications to improve outcomes for infants affected by BPD. The study also highlights potential areas for future investigation, including the development of novel therapeutic strategies targeting oxidative stress in BPD.
背景:支气管肺发育不良(BPD)是一种严重的慢性肺部疾病,主要影响早产儿,通常由长时间机械通气和氧疗引起。氧化应激在 BPD 的发病机制中起着关键作用,导致肺部损伤、炎症和肺发育受损。尽管进行了广泛的研究,但仍需要系统地描绘出该领域的研究趋势和热点,为未来的研究和治疗策略提供信息。
方法:本研究利用文献计量学和可视化分析,探讨了 2004 年至 2024 年氧化应激与 BPD 的全球研究趋势和热点。在 Web of Science 核心合集数据库中进行了全面的文献检索,重点关注与氧化应激和 BPD 相关的出版物。使用 VOSviewer、Citespace 和 R 包 Bibliometrix 等工具分析了合著关系、共引和关键词共现网络,以识别新兴的研究前沿和有影响力的研究。
结果:分析共确定了 597 篇相关文献,研究成果在 20 年期间呈稳步增长趋势,在过去十年中出现显著增长。美国在研究贡献方面处于领先地位,其次是中国和德国,这些国家之间有显著的合作。合著关系分析突出了关键的研究机构,如哈佛大学和加利福尼亚大学,它们是研究网络的中心节点。主题聚类揭示了五个主要的研究领域:抗氧化机制、炎症、分子途径、肺发育和治疗干预。关键词共现分析显示,随着时间的推移,研究重点发生了转移。早期研究集中于基本的病理生理机制,而最近的研究越来越关注先进的分子技术,如基因表达和靶向治疗。值得注意的是,该研究确定了一些新兴的研究热点,包括细胞外囊泡和细胞衰老在 BPD 中的作用,以及超氧化物歧化酶模拟物等抗氧化剂的潜在治疗应用。
结论:本文献计量学研究全面概述了氧化应激与 BPD 的研究现状,确定了关键趋势、有影响力的作者和新兴的研究主题。研究结果强调了在该领域继续开展研究的重要性,特别是将基础科学见解转化为临床应用,以改善 BPD 患儿的预后。该研究还突出了未来研究的潜在领域,包括针对 BPD 中氧化应激的新型治疗策略的开发。
