基于WOS的纳秒脉冲技术治疗肿瘤的基础研究态势分析

Analysis of Research Status of Nanosecond Pulse for Tumor Treatment Based on WOS

目的了解纳秒脉冲技术在肿瘤治疗领域的研究现状以及分析各国研究的发展趋势。方法在Web of Science中检索纳秒脉冲治疗肿瘤相关的科技文献,利用文献计量学方法,从论文数量、关键词聚类、发文国家和机构以及论文的国际间合作等角度,对纳秒脉冲技术治疗肿瘤领域的研究态势进行分析。结果全球纳秒脉冲技术治疗肿瘤领域的文章共有530篇,2004—2022年发文量的年复合增长率为7.2%。美国的发文量(229篇)、总被引频次(9280次)和篇均被引频次(40.52次/篇)均位于世界首位,中国的发文量(112篇)和总被引频次(1151次)虽仅次于美国,但篇均被引频次(13.39次/篇)排名第7。发文量累积超过20篇的机构共有21家,其中美国和中国分别有9家和4家。结论全球纳秒脉冲技术治疗肿瘤领域在近20年有较大幅度增长。美国在该领域的研究规模最大且实力最强,我国在该领域的影响力仍需提高,应进一步提升研究质量,增加国际合作,同时加强临床实践研究。

Objective To understand the research status of nanosecond pulse technology for tumor treatment and analyze the research trend in different countries.Methods Scientific papers regarding nanosecond pulse technology for tumor treatment were searched in Web of Science.Bibliometric analysis was conducted to analyze the research status in this field from the perspective of the number of papers,keyword co-occurrence,published countries and institutions,and international cooperation of papers.Results A total of 530 articles were published in the field of nanosecond pulse technology for tumor treatment with an annual compound growth rate of 7.2%from 2004 to 2022.The United States ranked first in the world in the number of articles published(229 papers),total citations(9280 times)and average citations per paper(40.52 time/paper).Although China ranked second on the number of articles(112 paper)and total citations(1151 times),the average citations per paper(13.39 time/paper)ranked 7th globally.A total of 21 institutions published more than 20 articles,including 9 in the United States and 4 in China.Conclusion The field of nanosecond pulse for tumor treatment has increased significantly in the past 20 years.Many studies have been conducted on the mechanism of this technique to tumor cells.The United States has the largest and strongest research scale in this field,while China has relatively less influence in this field.Therefore,China should further improve the quality of published articles,increase international cooperation and strengthen study of clinical practices.
