CNKI脑梗死后出血性转化高被引文献的计量分析

Quantitative Analysis of Highly Cited Literature on Hemorrhagic Transformation after CNKI Cerebral Infarction

摘要: 目的：用文献计量学的方法分析我国脑梗死后出血性转化的高被引文献。方法：在中国学术期刊全文数据库(CNKI)中检索1979~2021年的脑梗死后出血性转化文献，参照普赖斯定律确定高被引文献，用Excel软件统计分析被引频次、发表年份、期刊、作者姓名、作者单位、关键词、基金。结果：使用高级检索，高被引文献共有176篇，被引频次分别为7~89次，共被引2555次，平均每篇被引14.52次；文献数自2003年开始增长到2017年达到峰值26篇，近几年有所下降；文献分布在96种期刊，文献数、总被引频次、篇均被引频次均占第1位的杂志是《脑与神经疾病杂志》；文献作者共555人、署名608次，总合作率88.06%；作者机构158个，医院占63.29%，核心发文机构88.89%为院校，署名文献数前3位分别是河北医科大学、首都医科大学、中南大学；涉及关键词254个、共使用756次，“出血性转化”、“脑梗死”、“危险因素”、“急性脑梗死”、“静脉溶栓”的使用频次位于前5位；46篇文献获基金59项次，其中省级基金占77.97%。结论：CNKI数据库脑梗死后出血性转化高被引文献呈现了权威期刊是《脑与神经疾病杂志》、核心发文机构是院校、脑梗死后出血性转化危险因素是主要研究对象、主要资助基金是省部级以上项目，研究人员及机构广泛，需要规范使用关键词、该研究资助基金偏少。

Abstract: Objective: To analyze the quantitative analysis of highly cited literatures on hemorrhagic transfor-mation after cerebral infarction in China. Methods: The Chinese Academic Journals Full-text Data-base (CNKI) was searched from 1979 to 2021 for hemorrhagic transformation literature after cere-bral infarction, and the Price’s Law is used to determine the highly cited literature. Using Excel 2021, we analyzed the frequency and years of being cited, the cited journals, authors and institu-tions, keywords, and grants. Results: 176 highly cited papers were retrieved, with 7 to 89 citations respectively, a total of 2555 citations, and an average of 14.52 citations; the number of papers in-creased from 2003 to a peak of 26 in 2017, and in recent years the number of documents are de-creased; Literature is distributed in 96 journals, in these journals, Journal of Brain and Neurological Diseases remained the top number, the total frequency, and the mean frequency of being cited; there are 555 authors, 608 signatures. The rate is 88.06%; 158 author institutions are involved, 63.29% of which are hospitals, 88.89% of the core issuing institutions are colleges, and 3 units in-cluding Hebei Medical University, Capital Medical University, and Central South University are in the top 3 in the number of signed documents; 254 keywords are involved, used 756 times, with “hemorrhagic transformation”, “cerebral infarction”, “risk factors”, “acute cerebral infarction” and “intravenous thrombolysis” as the first 5 in the frequency of use. 46 papers have been funded 59 times, of which provincial funds account for 77.97%. Conclusion: The highly cited literatures of hemorrhagic transformation after cerebral infarction in CNKI database are presented with “Journal of Brain and Neurological Diseases” as the authoritative journal, with universities as the core pub-lishing institutions, the main research object is the risk factors of hemorrhagic transformation after cerebral infarction, the main funding funds are the provincial and ministerial level; with a wide range of researchers and institutions, but the keywords need to standardize and the funding funds are relatively small.
