利用GoPubMed对骨质疏松研究的文献计量学分析

摘要

Objective To analyze the present situation and development trend of osteoporosis, in order to provide information for further research. Methods Using ‘osteoporosis ’ as the key word to search literatures in GoPubMed ( 1946 - 2014 ) , the distribution of literatures by year, area, publication journals, and main authors was analyzed. Results The total number of articles published globally about osteoporosis was 53838. The literature number increased year by year from 1984 to 2014, reaching 3120 in 2014. The leading country in osteoporosis research was the United States (12,057, 22�39%), followed by Japan (3,292, 6�11%), and China ranked the sixth (2,005, 3�72%). The density of literature publication was high in Eastern United States, European countries, and Japan. Of the 20 top literatures output cities, six of them were in the United States, and three of them were in China, including Beijing (307 papers), Shanghai (274 papers), and Hong Kong (265 papers). The publication in these 3 cities accounted for 42�19% of the total publication in China. Most of the 20 top journals about osteoporosis research were from the United States and European countries. There were only two from Japan in Asia. Of the 20 top authors of osteoporosis research literatures output, there was no Chinese author. Conclusion GoPubMed is a valid tool to analyze the current situation and development trend of osteoporosis research. The literature number has been increasing year by year progressively, indicating that the research about osteoporosis is still a hotspot. However, most of the research is concentrated in the United States, European countries, and Japan. The research from China and other developing countries is weak.%目的：探究骨质疏松的研究现状及未来发展趋势，从而为进一步研究提供参考依据。方法利用GoPubMed检索工具，以“骨质疏松”为主题词检索PubMed数据库中骨质疏松相关的研究文献（1946－2014），并对文献发表的时间分布、地域分布、期刊分布及高产作者等项目进行统计分析。结果骨质疏松研究的文献共检出53838篇，发表量自1984年至今呈逐年上升趋势，2014年达3120篇。文献发表量最大的国家是美国（12057篇，22�39％），其次是日本（3292篇，6�11％），中国第六位（2005篇，3�72％）。美国东部、欧洲及日本发表文献的密度相对较高。发文量前20的城市中美国所占城市最多（6个），其次是中国，有北京、上海、香港3个城市，且其发文量分别为307篇、274篇、265篇，占中国总发文量的42�19％，其他地区相对较少。文献发表排名前20的主要期刊大都分布在欧美国家，亚洲只有日本有两种期刊，中国目前没有。发文量排名前20的核心研究者中目前没有中国作者。结论利用GoPubMed能较好地反映骨质疏松研究的现状与发展趋势。近年来骨质疏松症领域研究文献呈逐年上升趋势，是医学界研究的热点之一。但从文献发表的地域分布、期刊分布及高产作者分布可以看出，骨质疏松研究目前主要集中在欧美及日本等发达地区，中国及发展中国家相对较为薄弱。
