重离子研究现状分析

Analysis on Research Status of Heavy ion

目的采用社会网络分析方法和文献计量学的分析方法对重离子的研究现状进行全面分析。方法通过检索Pub Med获得重离子研究,采用挖掘软件对作者、国家、发表年代、主题词和期刊名称进行抽取和整理。采用SPSS17.0进行数据分析,作者、国家、发表年代和期刊名称均采用频数和率进行描述性分析。采用Net Draw软件呈现作者和主题词之间的关系,并绘社会网络图。结果共获取907篇相关重离子研究,重离子研究发表的数量逐年上升,作者的国家主要集中在日本、德国和中国,碳离子的研究较多,而氖离子和氦离子的研究相对较少;在研究内容方面,除了重离子治疗肿瘤的临床研究外,既有重离子在动物和肿瘤细胞方面的基础研究,还有重离子设备的设计等方面的研究,涉及的肿瘤类型多达30余种。结论重离子研究的数量不断增加,但存在地区发展不平衡,研究主题不但涉及重离子的临床研究和基础研究,也涉及重离子设备与设计。

Objective To analyze the status of research on heavy ion using the social network analysis methods and ana- lytical methods bibliometric methods. Methods PubMed was searched to include all relevant research on heavy ion. The related software was used to extract the information of author, country, year of publication, publication year, MeSH terms and journal name. SPSS17.0 was used to analyze the frequency and percentage. NetDraw software was used to draw the social network plot. Results 907 studies were retrieved, The number of studies on heavy ion were increased from 1975 to 2014, the author mainly came from Japan, Germany and China, the number of research on carbon ions were more than the number of research on neon ion and helium ion ; the published paper focused on the clinical research on the effectiveness of heavy ion for cancer, at the same time, heavy ions of animal, tumor ceils and equipment design were also concered,30 kinds of tumor were researched. Conclusion The number of research on heavy ion are increased, but there is an imbalance in regional development, the research topic focused on the clinical research and basic research topics, at the same time, the equipment and design of heavy ion are concered.
