我国新生儿持续肺动脉高压文献的可视化研究

Visualization Research of Literature on Persistent Pulmonary Hypertension of Newborn in China

目的:利用共词分析法对近10余年来国内关于新生儿持续肺动脉高压(PPHN)的文献进行可视化研究,总结目前国内该领域的研究热点和趋势。方法:在中国知网(CNKI)以"新生儿""持续肺动脉高压"为自由词,限定期刊年限为2000年1月至2017年11月,将符合研究标准的期刊文献,利用Bicomb 2书目共现软件、Excel进行关键词的统计及分析,再运用Ucinet 6. 0软件NETDRAW功能描绘关键词共现网络图,展示高频关键词之间的共篇关系。结果:最终纳入文献256篇,提取高频关键词30个,成功展示国内目前新生儿持续肺动脉高压的研究热点,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:国内关于PPHN的治疗是当前主要研究热点,而关于该病的诊断及发病机制尚需进一步研究。

Objective: To visualize the literature on persistent pulmonary hypertension of newborn (PPHN) with co-word analysis method over the past 10 years, and to summarize the current domestic research hot spots and tendency in this field. Methods: CNKI was retrieved with “newborn” and “persistent pulmonary hypertension” as the key words to identify the literature published from Jan. 2000 to Mar. 2017. The literature in accordance with the research criteria were statistically analyzed by using Bicomb2 bibliographic co-occurrence software and Excel. Ucinet 6.0 software NETDRAW was used to depict the co-occurrence network graph of keywords and to show the co-discourse relationship between high-frequency keywords. Results: Finally, 256 articles were included and 30 high-frequency keywords were extracted to successfully demonstrate the current research hot spots of PPHN in China. Through the demonstration of the co-occurrence analysis graph, the inner connection of different high-frequency keywords was depicted. Conclusion: The main research focus of the domestic research is on the treatment of PPHN, yet the diagnosis and pathogenesis of the disease still need to be further studied.
