新生儿黄疸研究现状的共词分析

A co-word analysis of current research on neonatal jaundice

目的将共词分析引入新生儿黄疸的现状研究,通过对近年来该领域研究现状进行统计分析,总结目前国内在该领域的研究重点和趋势。方法在中国知网以"新生儿""黄疸"为自由词,限定期刊年限为2009年1月至2013年7月,通过严格的纳入和排除标准,收录符合研究标准的文献,利用Excel 2013进行关键词统计及分析,通过Ucinet 6.0及Netdraw描绘共现分析图,展示高频关键词之间的共篇关系。结果最终纳入文献2 054篇,提取高频关键词44个,成功展示国内目前新生儿黄疸的研究热点,通过共现分析图的呈现,描绘了不同高频关键词的内在联系。结论国内新生儿黄疸的临床表现及诊断的研究已比较深入,但病因机制和治疗措施有待进一步研究。

Objective To investigate the research on neonatal jaundice in recent years by co-word analysis and to summarize the hot spots and trend of research in this field in China. Methods The CNKI was searched with “neonate” and “jaundice” as the key words to identify the papers published from January 2009 to July 2013 that were in accordance with strict inclusion and exclusion criteria. To reveal the relationship between different high-frequency key words, Microsoft Office Excel 2013 was used for statistical analysis of key words, and Ucinet 6.0 and Netdraw were used for co- occurrence analysis. Results A total of 2 054 papers were included, and 44 high-frequency key words were extracted. The current hotspots of research on neonatal jaundice in China were displayed, and the relationship between different high-frequency key words was presented. Conclusions There has been in-depth research on clinical manifestations and diagnosis of neonatal jaundice in China, but further research is needed to investigate the etiology, mechanism, andtreatment of neonatal jaundice.
