ObjectiveTo explore the current status and tendency of the application of CT or MRI in the pancreatic pseudocyst using bibiometric analysis for relative documents, and provide reference information for the future research of radiology. MethodsBibliographies from research literatures of CT or MRI application in the pancreatic pseudocyst from January 1, 2003 to September 20, 2014 in PubMed database were downloaded.The publication years, journals, the first authors, and the frequency of subject headings and subheadings were extracted from them by Bicomb 2.0 software.The subject headings and subheadings appeared more than five times were intercepted as high frequency ones, then created the high frequency subject headings and subheadings co-occurrence matrix.SPSS 22.0 statistical software was applied for clustering analysis with this matrix, then got the major hotspots. ResultsA total of 342 literatures were screened out.The research of CT or MRI application in the pancreatic pseudocyst increased slowly year by year in recent 10 years, then slowly decreased after 2008 year.The related literatures were published in the 164 journals, in which 16 journals (115 literatures were published) were core area distribution according to the Bradford law.There were 10 authors at least 2 published literatures, in who Bhasin DK in USA published 7 literatures, was the most active researcher in this field.The number of high frequency subject headings and subheadings was 33 and among which 5 research hotspots were clustered. ConclusionResearch hotspots about CT or MRI application in pancreatic pseudocyst mainly focuses on five aspects below:pathology, diagnosis, therapy, complications, and etiology.
ObjectiveTo investigate researches on pancreatic neoplasms and molecular imaging in recent five years and provide reference information for the majority of professionals in deep research. MethodsBibliographies 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 co-occurrence matrix were formed. SPSS 22.0 statistical software were applied for clustering analysis with matrix, then to get the topic hotspots. ResultsA 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. ConclusionsResearches on pancreatic neoplasms and molecular imaging are mainly in terms of therapy and genetics, diagnosis and metabolism, radionuclide imaging, pharmacology and pathology.
ObjectiveTo investigate the hotspots from researches on imaging of pancreatic neuroendocrine tumor in recent five years. MethodsThe bibliographies from research literatures on imaging of pancreatic neuroendocrine tumor from 2010 to 2015 in PubMed database were downloaded. The Bicomb 2.0 bibliographies analysis software was used to count high-frequency of Mesh major topics (MJMEs). SPSS 22.0 statistical software was applied for clustering analysis with MJMEs, then to get the topic hotspots. ResultsA total of 357 literatures were screened out during the years of 2010-2015. The MJMEs which frequency > 13 were 28. Taken the 28 MJMEs into clustering analysis, then three research hotspots were clustered. ConclusionResearches on imaging of the pancreatic neuroendocrine tumor in recent five years are mainly in terms of imaging techniques, a comparative study of pathology and endoscopic ultrasonography-fine needle aspiration, imaging and disease treatment.
ObjectiveTo investigate researches on inflammatory pulmonary pseudotumor between 2010 and 2014 year and to provide reference information for the majority of professionals in deep research. MethodsBibliographies from research literature of inflammatory pulmonary pseudotumor between 2010 and 2014 year in PubMed database were downloaded, the publication year, journals, countries of publication, the first authors and the frequency of major topic headings were counted by Bicomb 2.0 software. The affiliations were analyzed artificially. Major topic headings appeared no less than three times were intercepted as high frequency terms and high frequency. Major topic headings co-occurrence matrix were formed. SPSS 22.0 statistical software was applied for clustering analysis with matrix, then to get the topic hotspots. ResultsA total of 62 literatures were screened out. The data of research trend, journals, research degree of different countries were acquired. The number of high frequency major topic headings was 12 and among which 4 research hotspots were clustered. ConclusionResearches on inflammatory pulmonary pseudotumor are mainly in terms of pathology, diagnosis and treatment, etiology, and immunoassay.
ObjectiveTo analyze the global status, hotspots, and trends in atrial fibrillation anticoagulation research.MethodsWe searched Web of Science Core Collection to collect relevant literature on atrial fibrillation anticoagulation from 2006 to 2020. The visualization software CiteSpace and VOSviewer were used to analyze co-citation, co-occurrence, and emergence analysis on publishing organizations, journals, and keywords and to explore the research hotspots and frontiers.ResultsA total of 11764 related studies were retrieved. In recent years, research on anticoagulation of atrial fibrillation has become increasingly popular. Most of the published researches were from North America, and the primary institution was the University of Birmingham. Research hotspots mainly focused on warfarin, stroke prevention, new oral anticoagulants, antithrombotic and anticoagulants, and complicating diseases. The research frontiers were the new oral anticoagulants, and the antithrombotic management of atrial fibrillation with coronary heart disease.ConclusionsThe global hotspot in atrial fibrillation anticoagulant research is warfarin, stroke prevention, new oral anticoagulants, antithrombotic and antiplatelet therapy, and complicated diseases. The research focuses on the study of novel oral anticoagulants and the antithrombotic management of atrial fibrillation complicated with coronary heart disease.
