目的利用文献计量学方法分析内科学各主要分支学科的研究前沿.方法根据期刊引证报告(JCR)中10个内科学分支学科(内分泌与代谢病学、心血管病学、血液病学、传染病学、肾脏病学、胃肠病学与肝病学、呼吸病学、风湿病学、重症医学、神经与精神病学)期刊的数目及各刊的影响因子,并咨询相应学科临床专家,选定50种期刊作为分析样本.从Web of Science下载2011年度上述期刊发表的论文及其引文,分别统计各学科引文频次并抽取其中的高被引论文,根据这些论文同时被引用的次数对高被引论文进行聚类分析,浏览各类别中高被引论文的标题和摘要,确定各类别的主要内容,以高被引论文聚类结果作为该学科的知识基础,分析引用这些高被引论文的当前(2011年)论文获得各分支学科的研究前沿.结果从10个内科学专业分支学科中挑选了最具权威性的50种临床期刊；各学科总计挖掘出202条的高被引文献,38个高被引论文聚类(知识基础),与各知识基础对应的2011年发表的152篇代表性论文,以及对这些代表性论文内容分析归纳的结果.结论本研究确认并展示了10个内科分支学科的前沿进展,勾勒出当前各分支学科发展科研活动的静态结构.

Objective To outline the research fronts of ten major sub-specialties in internal medicine.Methods Based on their impact factor scores and the proportion of the journals of 10 subspecialties (endocrinology & metabolism,cardiac & cardiovascular systems,hematology,infectious diseases,nephrology,gastroenterology & hepatology,respiratory system,rheumatology,critical care medicine,clinical neurology) in Journal Citation Report (JCR),and careful consulation of expert clinicians,we identified 50 journals.Their bibliographic records (including references) published in 2011 were downloaded,and the frequency of the references (citations) in each sub-specialty was counted and the highly cited records were extracted.We performed a clustering analysis according to the co-cited times among any pairs of the highly cited records.To tag each cluster of highly cited records,we browsed the titles and abstracts of all highly cited records in the same cluster,and concluded the main topics of each cluster.Finally,we extracted the current published papers devoted to particular cluster by some clustering analysis indicators.The clusters of highly cited records were considered as the intelligence base,and the main topics in current papers which citing these highly cited papers were considered as research fronts.Results Totally 50 journals on 10 sub-specialties in internal medicine were identified.A total of 202 highly cited papers,38 clusters (knowledge bases),and 152 corresponding current citing papers presenting the research fronts were selected.Conclusions We confirm and present research fronts in 10 major sub-specialties of internal medicine.This study provides a synchronic structure of contemporary research activities in internal medicine sub-specialties.
