基于SCI数据库的我国干细胞领域研究状况的词频计量分析

The Word Frequency Quantitative Analysis of the Research Status of Stem Cell Field in China based on SCI Database

以SCI数据库全库收录的2000-2013年间我国发表的干细胞领域文献为研究对象,基于关键词词频、共现词频、节点中心度等多个角度,通过利用信息可视化软件Cite Space III和Bibexcel工具对文献关键词进行了较为全面的分析。研究结果表明:主题词EXPRESSION (表达)、DIFFERENTIATION(分化)、STEM-CELLS(干细胞)、TRANSPLANTATION(移植)、IN-VITRO(体外)、MESENCHYMAL STEM-CELLS(间充质干细胞)、PROLIFERATION(增殖)、PROGENITOR CELLS(祖细胞)、STROMAL CELLS(基质细胞)、BONE-MARROW(骨髓)、GROWTH(生长)等始终保持在所有主题词的前列,表明我国干细胞研究领域的热点学科为生命科学类学科。

The literature on the data of stem cell has been published in China from 2000 to 2013 in SCI database.This paper makes a comprehensive analysis of the key words from the perspectives of keyword frequency,co-occurrence frequency and node centrality by using the information visualization software CiteSpace III and Bibexcel tools.The result of the study shows that the keywords include EXPRESSION,DIFFERENTIATION,STEM-CELLS,TRANSPLANTATION,IN-VITRO,MESENCHYMAL STEM-CELLS,PROLIFERATION PROGENITOR CELLS,STROMAL CELLS,BONE-MARROW,and GROWTH etc.,which have always been at the forefront of all the keywords,indicating that the hotspots in the field of stem cell research in China are life science.
