基于PubMed慢性肾脏病患者运动研究共词热点聚类分析

目的 了解慢性肾脏病患者运动领域研究现状和热点,为研究人员进行该领域的研究提供参考。方法 检索PubMed数据库中2009—2018年发表的慢性肾脏病运动的文献,运用书目共现分析软件（Bicomb 2.0）统计主题词词频,用SPSS 20.0对高频主题词进行共词聚类分析。结果 共检索到1 779篇文献。获得高频主题词33个,占总频次的30.1%。共词聚类分析总结出近10年慢性肾脏病患者运动研究的5个热点,分别为：运动对慢性肾脏病患者在心血管功能、肾功能、生活质量3个方面影响的研究,以及运动方案、运动相关生理学和病理生理学机制2个方面的研究。结论 慢性肾脏病患者运动相关的研究日趋受到国内外学者的重视,研究重点集中于探讨慢性肾脏病患者在心血管功能,肾功能和生活质量改善方面的运动获益,慢性肾脏病患者运动方案的设计以及相关机制探讨,但目前缺乏大样本、多中心干预性临床研究,在护理领域该方面的研究较少。

Cluster Analysis of Literatures Hotspots on Exercise of Patients with Chronic Kidney Disease in PubMed

Objective To identify the research status and hotspots of exercise in patients with chronic kidney disease (CKD) in PubMed, and to provide reference for researchers in this field. Methods The literatures on exercises of CKD patients in PubMed from 2009 to 2018 were searched. The word frequency of the subject words was counted using Bicomb2.0 software, and the co-word clustering analysis of the high-frequency subject words was conducted with SPSS 20.0. Results A total of 1,779 articles were retrieved. Thirty-three high-frequency subject words were extracted, accounted for 30.1% of the total frequency cumulatively. Five hot research areas were identified including the effect of exercise on cardiovascular function, renal function and quality of life of CKD patients, exercise program, and studies on exercise physiology and pathophysiological mechanisms in CKD patients. Conclusion The research on exercises of CKD patients receives increasing attention from domestic and foreign scholars. The research focuses on the benefits of exercises for CKD patients in improving cardiovascular function, renal function, and quality of life, the design of exercise programs and its related mechanisms, but lacks large sample, multicenter intervention clinical study, and there are fewer related studies in the field of nursing.
