基于SCI数据库收录文献分析镁合金植入物在骨科的应用

The literature research analysis of magnesium alloys as metal implants in orthopedics based on Science Citation Index database

背景:镁合金作为骨科植入材料,已经引起国内外越来越多研究者的关注。目的:利用SCI数据库检索镁合金植入物在骨科应用的10年文献,进行多层次探讨分析。设计:文献计量学分析。资料提取:以"magnesiumalloy(镁合金),rod(镁合金棒),screwornail(螺钉),boneplate(接骨板)"为关键词,检索SCI数据库2002-01/2011-12的相关文献,以文字和图表的形式进行统计和计量分析,描述其分布特征。入选标准:纳入标准:检索与镁合金植入物,镁合金棒、镁合金螺钉、镁合金接骨板在骨科应用的相关文献。文献类型包括:①论著。②综述。③会议记录及摘要。④快报。⑤社论。⑥信件。排除标准:①与文章目的无关的文献。②大于10年较陈旧的文献。③未发表的文章。④需电话追踪和手工检索逐一分析的文章。主要数据判定指标:镁合金植入物在骨科应用文献的出版时间、来源期刊、文献的类型、学科类别、文献被引情况、国家地区分布、机构分布、发表文献的作者分布,基金资助情况进行相关分析。结果:SCI数据库2002/2011收录的文献中共检索到388篇镁合金植入物在骨科应用的相关文献,论著位居首位,其中6篇可以确定为经典文献。文献数量2002/2011呈总体上升趋势,MaterialsScienceForum《材料科学论坛》杂志发表文献量最多,42篇,占全部文献的10.83%。结论:对来源于SCI数据库镁合金植入物在骨科应用的文献进行文献计量学分析,可为了解该领域的概貌、现状和研究者进一步确定热点难点提供有价值的参考。

BACKGROUND： Magnesium alloys as orthopedic implant materials have given rise to more and more researchers’ attention at home and abroad. OBJECTIVE： To multivariately analyze the literature regarding magnesium alloys as metal implants in orthopedics through Science Citation Index Database （SCI）. DESIGN： Bibliometric analysis. DATA RETRIEVAL： A retrieval was performed for the literature of magnesium alloys as metal implants used in orthopedics, including magnesium alloy, rod, screw or nail, bone plate published during 2002-01 and 2011-12 in SCI. The retrieval results were analyzed, and the trends were described in words and graphics. SELECTIVE CRITERIA： Articles on magnesium alloys as metal implants in orthopedics included the following types： （1）Peer-reviewed original articles; （2）Reviews; （3）Meeting notes and abstracts; （4）Proceeding papers; （5）Editorial; （6）Letters. Exclusive criteria included （1）Articles unrelated to the study of magnesium alloys as metal implants in orthopedics. （2）Articles published before 2002. （3）Articles which were not published on journals. （4）Articles which were retrieved by phone or manually. MAIN OUTCOME MEASUREMENTS： The literatures were analyzed by publication year, journal distribution, type of document, discipline distribution, citation frequency, national distribution, institutional information, the fund and authors. RESULTS： A total of 388 articles on magnesium alloys as metal implants in orthopedics were retrieved in SCI database, in which most of papers were published as original articles. Six articles were identified as classic literature. The overall number of literature had an upward trend from 2002 to 2011. Materials Science Forum published most papers in this field （n=42, 10.83%）. CONCLUSION： This paper provides a valuable reference for researchers to understand the overview and present situation of this field in order to set further research.
