基于文献计量学的最近5年胰腺肿瘤分子影像学研究热点分析

Bibliometric and Research Hotspots Analysis of Pancreatic Neoplasms and Molecular Imaging in Recent Five Years

目的了解最近5年来胰腺肿瘤分子影像学领域的研究状况,为广大专业研究人员提供参考信息。方法下载PubMed数据库中最近5年发表的胰腺肿瘤分子影像学研究文献题录,使用Bicomb 2.0软件统计分析文献的发表年代、来源期刊及期刊所属国家、第一作者以及高频主要主题词分布情况,对文献第一作者所属研究机构进行人工逐条统计分析。将出现频次不小于2次的主要主题词作为高频主要主题词,建立词篇矩阵,使用SPSS22.0软件进行聚类分析,得到该领域的研究热点。结果筛选出相关文献28篇,获得该领域研究热度趋势、来源期刊分布、各国研究热度等数据资料。高频主要主题词共计20个,通过对高频主要主题词进行聚类分析,得到5个主要研究热点方向。结论最近5年来胰腺肿瘤分子影像学研究热点主要集中在治疗与基因、诊断与代谢、核医学成像、药理学及病理学5个方向。

Objective To investigate researches on pancreatic neoplasms and molecular imaging in recent five years and provide reference information for the majority of professionals in deep research. Methods Bibliographies from research literature of pancreatic neoplasms and molecular imaging in recent five years in PubMed database were downloaded. The publication years, journals, countries of publication, the first authors and the frequency of MJMEs were counted by Bicomb 2.0 software. The affiliations were analyzed artificially. MJMEs appeared no less than two times were intercepted as high frequency ones and the high frequency MJMEs matrix were formed. SPSS 22.0 statistical software were applied for clustering analysis with matrix, then to get the topic hotspots. Results A total of 28 literatures were screened out. The data of research trend, journals, research degree of countries were acquired. The number of high frequency MJMEs were 20 and among which 5 research hotspots were clustered. Conclusions Researches on pancreatic neoplasms and molecular imaging are mainly in terms of therapy and genetics, diagnosis and metabolism, radionuclide imaging, pharmacology and pathology.
