CNKI中儿童过敏性紫癜高被引文献的计量分析
A Quantitative Analysis of Cited Literature with High Frequency of Children’s Allergic Purpura in CNKI

目的：对国内过敏性紫癜患儿高被引用文章进行统计学处理。方法：以中国医学期刊全文数据库(CNKI)为例，以普赖斯法则为基础，采用Excel 2010对被引、年份、期刊、作者、单位、关键词、基金等进行分析。结果：共检索到194份高被引论文，其中14~326条，累积1053条，10567条；从2001年起，论文数量逐渐增加，到2017年达到21个高峰，随后急剧减少；其中，《临床儿科杂志》《中国实用儿科杂志》《中国当代儿科杂志》均保持着较高的引用频率和被引频率的排名；论文作者606篇，题名1705篇，合著者总数占35.54%，其中以鹿玲为第一，吴小川为第二，张琴为第三；136家科研院所，包括：68.2%的医院，安徽医科大学3所，郑州大学3所，深圳市儿童医院3所；关键词：8,351,006次，出现频率最高的5个关键词为“皮肤紫癜”，“过敏性紫癜”，“临床疗效”，“Schonlein”，“复发率”；研究项目52个，共资助52个项目，包括部、市级及以下项目的资金投入比例为70.27%。结论：《临床儿科杂志》《中国实用儿科杂志》《中国当代儿科杂志》三家权威期刊，医院作为核心期刊，以儿童过敏性紫癜的诊治为主要研究对象，省级及以上课题为主要资助对象，以鹿玲，吴小川，张琴为核心研究小组，存在着关键字运用不规范，资助经费不足等问题。
Objective: To analyze the bibliometric analysis of high citation literature in children with purpura. Methods: Literature on children’s allergic purpura from June 30, 1981 to November 27, 2022 was retrieved from China Academic Journal Full-text Database (CNKI). References with high citation rate were determined according to Price’s law. Citation, year, journal, author, unit, keyword and fund were analyzed statistically by Excel 2010. Results: 194 highly cited literatures were detected, which were cited 14~326 times respectively, with a total of 10053 citations and an average of 5.67 citations. The number of literatures increased from 2001 to the peak of 21 in 2017, and then decreased rapidly. The literature was distributed in 132 journals, of which Journal of Clinical Pediatrics, Chinese Journal of Practical Pediatrics and Chinese Journal of Contemporary Pediatrics ranked the first 3 in terms of number of literatures, total citation frequency and average citation frequency. There were 606 authors with 1705 signatures, with a total cooperation rate of 35.54%. The number of signatures of Lu Ling, Wu Xiaochuan and Zhang Qin ranked the top 3. There were 136 author institutions, of which 68.52% were hospitals and 49.07% were colleges and universities. Anhui Medical University, Zhengzhou University and Shenzhen Children’s Hospital ranked the top 3 in terms of signed literatures and converted literatures. Involving 835 keywords, 1006 times, “skin purpura”, “allergic purpura”, “clinical effect”, “Schonlein”, “recurrence rate” in the top 5
