Abstract

Abstract:

ACKGROUND: Perthes disease has been widely concerned since it was discovered. Research and exploration of the disease are also deepening.

OBJECTIVE: To explore the current research and development trend of Perthes disease in the worldwide.

METHODS: The scientific citation index of Wed of Science core collection was used to retrieve literature on Perthes disease from 1994 to 30 July, 2018, and to use the bibliometric method to conduct data statistics and analysis. Using Vos viewer software was used to carry out visual transformations such as document coupling analysis and co-occurrence analysis, and the research status and development trend of Perthes disease in the worldwide was analyzed.

RESULTS AND CONCLUSION: (1) Totally 1 106 researches were included. The global research direction and research publications are increasing yearly. Among them, the United States remains a leader in this field of research, whose number of citations and H index are the highest, far exceeding the second country. (2) The publications of "JOURNAL OF PEDIATRIC ORTHOPAEDICS" magazines ranked the top, to 125 publications. (3) “TEXAS SCOTTISH RITE HOSP CHILDREN” is the organization that contributed the most in the literature. (4) The current research direction can be divided into five categories: disease assessment, disease characteristics, disease diagnosis, pathogenesis and necrosis", of which “inflammation” and “ischemic osteonecrosis” research is a new point of concern in recent years. (5) The prediction from the current global trends indicates that we have many directions to explore this disease, and the number of corresponding literature publications will continue to increase. Among them, the United States maintains a clear leading position in this field. The current research focuses on “disease characteristics” in Perthes disease, and "score" are recently new concerns in this field.

2.2 Perthes病在不同领域的出版物分析 2.2.1 各期刊杂志发表量分析图2A为该领域文献发表量在全球范围内排行前20的期刊杂志分布情况。根据此次研究所统计的数据显示，在Perthes病领域，《JOURNAL OF PEDIATRIC ORTHOPAEDICS》杂志发表文献最多，共125篇，其次是《JOURNAL OF PEDIATRIC ORTHOPAEDICS PART B》杂志共发表100篇，《CLINICAL ORTHOPAEDICS AND RELATED RESEARCH》杂志共发表72篇，《JOURNAL OF BONE AND JOINT SURGERY AMERICAN VOLUME》杂志共发表47篇，《JOURNAL OF BONE AND JOINT SURGERY BRITISH VOLUME》杂志共发表44篇。 2.2.2 研究方向分析随着Perthes病的发现与发展，人们对其病因、发病机制、诊治的研究也不断深入。图2B显示了当前Perthes病的研究方向，其中最主要的几个研究领域包括整形手术、儿科学、外科手术、影像学、运动科学。 2.2.3 研究机构文献发表数量分析图2C为全球对Perthes病进行研究的机构所贡献的文献数量排行前20的机构名称分布。其中“Children Hospital”与“Texas Scottish Rite Hospital For Children”共列第1位，发表文献最多(40篇)，“Harvard Univ”排名其次(32篇)，“Shriners Hospital for Children”排名第3位(25篇)。 2.2.4 作者文献发表数量分析图2D显示了全球范围内在该领域文献发表量排行前20的作者排名，其中发表量最多的前3位作者是“KIM HKW”(40篇)、“JOSEPH B”和“KRAUSPE R”(18篇)。 2.2.5 基金支持研究科学研究离不开研究基金的大力支持，图2E列出了全球范围内提供基金支持产出文献发表量排行前20的基金项目，其中基金项目“Texas Scottish Rite Hospital For Children”(德克萨斯苏格兰礼仪儿童医院)排名第一，共支持发表12篇文献研究。基金项目“NIAMS NIH HHS”(美国国立关节肌肉骨骼及皮肤病研究所)排名第二，共支持发表7篇文献研究。“National Institute For Health Research”(英国国家健康科学研究所)排名第三，共支持发表6篇文献研究。“National Natural Science Foundation Of China”(中国国家自然基金)排名第四，共支持发表 5篇文献研究。“NIH”(美国国立卫生研究院)排名第五，共支持发表5篇文献研究。 2.3 全球研究的可视化分析 2.3.1 文献耦合分析文献耦合分析图见图3，文献耦合是指文献之间通过参考文献进行的耦合，可分为论文耦合、学科耦合、著者耦合以及期刊耦合等类型。此外，还有文献所属国别耦合、文献语种耦合等。而耦合的强度取决于共同参考文献(被引文献)的数量。该种类型的分析被广泛应用于情报科学、文献计量学、科学学、未来学等领域当中。 (1)著者耦合分析：纳入的全部引文资料共包括3 496 位著者，通过定义每位作者至少有3篇文献相关联，共纳入 296位著者，见图3A，其中在该领域中发表文献的耦合强度排行前五的著者为：Kim HKW(总联系强度为45 097)；Josper B(总联系强度为24 116)；Wiig O(总联系强度为 22 665)；Krauspe R(强度联系次数为21 854)；Kim H(总联系强度为19 346)。 (2)机构耦合分析：纳入的全部引文资料共包括1 208个机构，通过定义至少存在3个组织机构的研究文献，纳入163个机构，见图3B，其中该领域发表文献的耦合强度排行前五的机构为：“TEXAS SCOTTISH RITE HOSP CHILDREN”(强度联系次数为25 926)，“CHILDRENS HOSP”(强度联系次数为21 214)，“HARVARD UNIV”(强度联系次数为15 591)，“SHRINERS HOSP CHILDREN” (强度联系次数为13 368)，“UNIV BERN”(强度联系次数为13 243)。 (3)国别耦合分析：纳入的全部引文资料共包括57个国家，通过定义至少存在3个国家的研究文献，纳入40个国家，见图3C，其中在该领域中发表文献的耦合强度排行前五的国家为：美国(强度联系次数为117 675)、英国(强度联系次数为42 101)、德国(强度联系次数为40 366)、韩国(强度联系次数为35 611)、日本(强度联系次数为31 669)。 2.3.2 共现分析 “共现分析”是对共现现象的定量研究，以揭示信息的内容关联和特征项所隐含的知识。而对关键词的共现分析是通过研究大量文档中的共现关系，分析共现关键词之间的链接强度，其目的是描述某一学科领域的内部构成关系和结构，揭示该学科的研究前沿[15]。 (1)研究方向分析：通过定义纳入关键词在出版物中使用超过5次的文献，并使用Vos viewer软件进行分析。软件识别出关键词共3 093个，符合条件纳入分析324个，见图4A，根据关键词可把目前全球的研究方向分为5个集群，大致为：疾病评估、疾病特征、疾病诊断、发病机制和坏死情况。在“治疗方法”研究中，常用的关键词有“手术治疗、保守治疗、控制治疗、骨盆截骨术、内翻截骨术、股骨头截骨术”。在“疾病特征”研究中，常用的关键词有“股骨头骨骺、髋部发育不良、撞击征、盂唇撕裂、骨折、变形”。在“临床诊断”研究中，常用的关键词有“一过性滑膜炎、化脓性关节炎、刺激性髋关节、放射摄影技术、超声检查、MRI”。在“发病机制”研究中，常用的关键词有“血栓形成、被动吸烟、C-反应蛋白、低纤溶的、血管畸形”。在“骨代谢疾病”研究中，常用的关键词有“骨质疏松、特发性关节炎、缺血性坏死、股骨头坏死、塌陷”。 (2)研究发展趋势分析：Vos viewer软件可以通过“Overlay Visualization”(叠加功能)对不同关键词在其对应的文献中所出现的平均时间进行颜色归类，使不同时间内的研究热点一目了然，见图4B。如图中的标尺所示，颜色越深表示关键字出现较早，属于既往的研究热点，随着时间的推移，图中颜色出现黑-灰-白的变化，越靠近白色部分表示近期的研究重点，且连接点的面积越大，表明其相关性越强。由图4可以分析得出，在2012年之前大多数研究集中在“治疗方法”、“临床诊断”、“发病机制”和“骨代谢疾病”的研究上。2012年之后研究重点集中于“疾病特征”，其中“评分”是该板块近年来提出的研究点。 "
