基于文献计量学的中国甲状腺外科热点分析

A bibliometric analysis of hotspots in thyroid surgery in China

目的分析1989-2018年我国甲状腺外科研究的热点和相关方向,以及探索不同区域研究热点差异性。方法以中国生物医学文献数据库(sinomed数据库)为目标数据源,用主题词的检索方式,检索时间定位于1989年1月至2018年12月。采用聚类分析方法,用书目共现分析系统获得相关数据资料的统计值;采用文献计量学方法,用布拉德福定律的应用公式可求得核心区期刊文献数量P=2Ln(e^E×Y),便可近似的分析出1989年到2018年中国专业学术期刊发表的有关甲状腺外科文献的主题词相关热点研究、核心期刊分布与文献量、地区文献研究差异,并获得甲状腺外科的近三十年总体的发展趋势。结果发文量和核心期刊分布特点:最终获得相关文献总量共7686篇。主题词分布特点:“手术后并发症”“喉返神经”“出血”在1989-1998年、1999-2008年、2009-2018年3个时段中出现频次均最高。地区文献的研究特点:分布在32个省(市)和地区。其中以广东省发文量最多,达到951篇,约占文献总量的13%。同时发现热门主题词在东中西三部的差异不具有统计学差异。结论我国甲状腺外科文献数量近三十年总体呈明显增长趋势;“手术后并发症”“甲状腺癌”“喉返神经”“甲状旁腺”和“出血”等主题词一直是甲状腺外科研究热点;不同地域间的甲状腺外科的研究方向不具有差异性,以广东、浙江为主的东南部省份发文量较多。

Objective To analyze the hotspots and related directions of thyroid surgery research in China from 1989 to 2018, and to explore the regional differences of research hotspots. Methods The Chinese Biomedical Literature Database (Sinomed) was used as the target data source, and the retrieval time was from January 1989 to December 2018. Cluster analysis method and bibliographic co-occurrence analysis system were used to obtain the statistical value of relevant data;the bibliometric method and the formula of Brad. ford's law were used to identified the number of journals in the core area, P =2Ln(e^E×Y). And the relevant hot research topics of thyroid surgery literature published in Chinese professional academic journals from 1989 to 2018 were approximately analyzed. The distribution of core journals is different from literature quantity and regional literature research, and the general development trend of thyroid surgery in recent 30 years is obtained. Results Total number and journal distribution features: 7 686 articles were retrieved. Distribution of the key words frequency like:"postoperative complication","recurrent laryngeal nerve"," haemorrhage" in 1989-1998, 1999-2008 and 2009-2018, was the highest. The research characteristics of regional literature were distributed in 32 provinces, cities and regions. Among them, Guangdong Province has the largest number of published papers, reaching 951, accounting for about 13% of the total litera. ture. At the same time, it was found that there was no statistical difference between the three regions of East, West and Central China. Conclusion In recent 30 years, the number of literature on thyroid surgery in China has been increasing markedly;the themes of "postoperative complications","thyroid cancer","recurrent laryngeal nerve","parathyroid gland" and "hemorrhage" have always been the hotspots of thyroid surgery research;the research directions of thyroid surgery among regions are not different, and there are more papers published in southeastern provinces, mainly in Guangdong and Zhejiang Province.
