普通外科3种生物材料国际发展态势：基于汤森路透Web of Science数据库的文献计量结果分析☆

 背景：医用生物材料是用于对生物体进行诊断、治疗、修复或替换其病损组织、器官或增进其功能的新型材料，己成为研究人工器官和医疗器械的基础学科。目的：对普通外科3大类生物材料，即腹壁修复材料、缝合材料以及止血材料进行文献计量学分析，评估该领域学术文献的总体趋势，为在该领域进行深入研究提供参考。设计：不同检索式的文献计量学分析。资料提取：以“surgery(普通外科)，patch(补片)，suture material(缝合材料)，hemostasis material OR hemostatic material OR hemostasia material(止血材料)”为关键词，检索汤森路透Web of Science数据库2006-01/2010-12的相关文献，将分析结果及资料导出，以文字和图表的形式描述。学科类别中选择普通外科，将结果导出并分析。纳入标准：纳入研究原著、综述、技术进展、会议录、编者的信和社论；排除会议摘要、书本章节、新闻、需手工检索和电话检索的文献。主要数据的判定指标：以相关文献的国家地区分布，基金资助情况，文献类型分析，高被引文章分析，发表年份分布，发文量较多的机构分析为结果分析判定指标。结果：Web of Science数据库收录的关于普通外科生物材料的文献中，以补片材料为主，文献量1 302篇。在补片材料、缝合材料和止血材料的研究中以美国的发文量最多，分别为395篇、199篇和144篇。而中国在这3个领域的研究在国际上有重要地位。结论：近几年来生物材料的研究趋于成熟，发文量稳定并且呈逐渐上升趋势，补片材料是目前生物材料领域研究的热点。

International development trends of three kinds of biological materials used in general surgery: A bibliometric analysis based on Web of Science database

BACKGROUND: Medical biomaterial is a new type of material which can be used in diagnosis, treatment, and repairing or replacing the lesion tissues or organs to improve their functions. Medical biomaterial has become a basic discipline in research of artificial organs and medical devices.   OBJECTIVE: To analyze the literatures on abdominal wall repair materials, suture materials or hemostatic materials used in general surgery and to evaluate the overall trend in this field to provide a reference for further research in the field.DESIGN: Bibliometric analysis based on different retrieval types.DATA RETRIEVAL: A search of related literatures was performed in Web of Science database from January 2006 to December 2010 using the key words of “surgery, patch, suture material, hemostasis material/hemostatic material/hemostasia material” in English. The retrieval results were analyzed, and the trends were described in words and graphics.SELECTION CRITERIA: The literatures included articles, reviews, technical studies, proceedings papers and letters. Unpublished articles, meeting abstracts, book chapters, news and those needed to be obtained by manual or phone search were excluded.MAIN OUTCOME MEASUREMENTS: The literatures were analyzed by national distribution, institutional information, foundation supporting, publish year, discipline distribution, and citation frequency. RESULTS: The number of literatures on patch was the most in Web of Science database, which was 1 302. Articles published by authors from USA were the most, including 395 papers about patch, 199 about suture material, and 144 about hemostatic material. China has occupied an important position in the international research of these materials.CONCLUSION: The research of biomaterial is becoming more mature, and the number of literatures in this field is increasing. Patch material is the research hot in recent years.
