CNKI中新生儿缺氧缺血性脑病高被引文献的计量分析

Bibliometric Analysis of Highly Cited Literature on Neonatal Hypoxic-Ischemic Encephalopathy in CNKI

摘要: 目的：分析我国新生儿缺氧缺血性脑病高被引文献的计量特征。方法：检索中国学术期刊全文数据库(CNKI) 1979~2025年发表的新生儿缺血缺氧性脑病的文献，参照普赖斯定律确定高被引文献，用Excel 2016统计分析被引频次、年份、期刊、作者、单位、关键词、基金。结果：检出高被引文献108篇，分别被引37~2322次，累计被引10,764次，篇均被引99.67次。时间分布上，高被引文献最早见于1991年，2000年达峰值12篇，1994~1999年呈上升趋势，2000年后波动下降；载文期刊共44种，《中国实用儿科杂志》《中华儿科杂志》等6种核心期刊载文占比60.19%，其中《中华儿科杂志》篇均被引最高，为386.67次；文献作者共189人，署名263次，总合作率61.11%。韩玉昆、邵肖梅、虞人杰的署名数依次居前3位；作者机构48个，其中医院占比68.20%，16个核心发文机构中院校占比81.25%，中国医科大学、复旦大学、浙江大学3个单位依次居署名文献数、折合文献数前3位；涉及关键词76个、363次，“缺氧缺血性脑病”、“新生儿”、“新生”、“脑缺血”、“脑缺氧”的使用频次居前5位；20篇文献获基金22项次，其中部省级以上基金占比90.90%。结论：新生儿缺氧缺血性脑病高被引文献集中于1994~2000年，核心期刊、院校附属医院及核心作者的研究视角聚焦于疾病诊断、亚低温治疗及预后，形成了以韩玉昆、邵肖梅、虞人杰等为代表的核心团队，但关键词使用不够规范，基金支持较少。

Abstract: Objective: To analyze the bibliometric characteristics of highly cited literature on neonatal hypoxic-ischemic encephalopathy in China. Methods: Literature on neonatal hypoxic-ischemic encephalopathy published from 1979 to 2025 was retrieved from the China National Knowledge Infrastructure (CNKI) database. Highly cited literature was identified in accordance with Price’s Law. Microsoft Excel 2016 was used to conduct statistical analysis on the following dimensions: citation frequency, publication year, publishing journals, authors, affiliated institutions, keywords, and funding support. Results: A total of 108 highly cited literature was identified, with citation frequencies ranging from 37 to 2322. The total number of citations reached 10,764, with an average of 99.67 citations per literature. In terms of temporal distribution, the earliest highly cited literature was published in 1991; the number of highly cited literature showed an upward trend from 1994 to 1999, peaked at 12 in 2000, and then fluctuated downward after 2000. The literature was published in 44 journals, among which 6 core journals (including Chinese Journal of Practical Pediatrics and Chinese Journal of Pediatrics) accounted for 60.19% of the total. Chinese Journal of Pediatrics had the highest average number of citations per literature, reaching 386.67. A total of 189 authors were involved, with 263 author signatures, and the overall collaboration rate was 61.11%. Yukun Han, Xiaomei Shao, and Renjie Yu ranked the top three in terms of the number of signatures. There were 48 affiliated institutions, among which hospitals accounted for 68.20%. Among the 16 core institutions (with high literature output), colleges and universities accounted for 81.25%. China Medical University, Fudan University, and Zhejiang University ranked the top three in both the number of signed literature and the converted number of literature. A total of 76 keywords were involved, with 363 occurrences; the top 5 keywords by frequency were “hypoxic-ischemic encephalopathy”, “neonate”, “newborn”, “cerebral ischemia”, and “cerebral hypoxia”. Twenty literature received support from 22 fund projects, among which ministerial and provincial-level funds accounted for 90.90%. Conclusion: Highly cited literature on neonatal hypoxic-ischemic encephalopathy is concentrated in the period from 1994 to 2000. Core journals, affiliated hospitals of colleges and universities, and core authors focus their research on disease diagnosis, hypothermia therapy, and prognosis, forming core research teams represented by Yukun Han, Xiaomei Shao, Renjie Yu, et al. However, the use of keywords is not standardized enough, and funding support for relevant research is relatively insufficient.
