| Purpose Based on database both at home and abroad the research papers of hypertensive heart disease as the research object,hypertensive heart disease research analysis of post trend both at home and abroad,high-yield authors,institutions,provinces and countries(regions)distribution.Besides using cooperation index and social network analysis of authors,institutions,both at home and abroad,provincial and national(regional)cooperation is analyzed,discover the Posting rules of hypertensive heart disease research and cooperation,and find out the high influence authors,institutions,provinces and countries(regions).Research Subjects This study selected 2012 world health organization issued a cause of death in the 10 th ranked hypertensive heart disease research paper record the data for the object.DataChinese data: To investigate the cooperation and development of studies in the field of hypertension heart disease in China,on the basis of all the published journal articles on CNKI and Wanfang Data Knowledge Service Platform.International data: To investigate the cooperation and development of studies in the field of hypertension heart disease in China,on the basis of all the published journal articles on Science Citation Index-expanded(SCI-E)and Social Science Citation Index(SSCI).Methods1.Literature analysis: Including books,periodicals,network information,etc.2.Scientomerics: Using the post indicators,to hypertension,heart disease research paper prolific authors,institutions,provinces and countries(regions)are analyzed.Using the index of cooperation condition of high blood pressure,heart disease research papers were analyzed.Using network analysis method to discover high blood pressure,heart disease research cooperation network of high influence authors,institutions,provinces and countries(regions)3.Social network analysis: Using social network analysis software,such as Pajek,Gephi and VOSviewer,implementation network centrality analysis and cluster analysis,and draw the network diagram Results 1.China(1)From the point of view the paper articles,the domestic study of hypertensive heart disease started earlier,document number,the number of the author,and authors passengers except for a few years have volatility is on the rise as a whole.After 1990,it is of exponential growth,the author number and people growth rate than paper.(2)From the perspective of cooperation,in 1959-2015,57.94% of hypertensive heart disease research papers in our country consists of two or more than two the author collaboration.Institutions and regional cooperation papers were 14.34% and 3.59% respectively,can be found in the low level of overall cooperation.And from the trend,the author cooperation rate and average number of authors,all showed a trend of decline,the organization cooperation rate,province cooperative rate,average number of institutions,the average number of provincial areas have been low.(3)Cooperation network analysis found that the author collaboration network cooperation frequency up to 16,and 97.05% even lines value is not greater than 2,the cooperation close degree is low.K-core analysis found that cooperation between hypertensive heart disease study author breadth level is low,86.92% under five nuclear in K – core.The author cooperation network in a large number of small scale cooperation group,the cooperation of hypertensive heart disease research papers is explained size and strength is not big.Through analyzing the author collaboration network centricity and author distribution analysis found that,Gui-qing Wang,Yi-feng Cao,Ji-ping Guo,Yong-ju Yang,Zu-lu Wang are the authors who have higher academic status and influence.For institutions were identificated and cooperation network analysis found that the General Hospital of Shenyang Military,the Chinese PLA general hospital,the First Affiliated Hospital of Suzhou University,Chinese Academy of Medical Sciences and other institutions while paper production is higher,but its in cooperation network centricity index is not top,visible,most of these institutions papers completed by the organization.For cooperation network centricity analysis found that,the Union Hospital Affiliated with Huazhong University of Science and Technology,Shanghai Institute of Cerebrovascular Disease,Fudan University,Changhai hospital affiliated to the Second Military Medical University and other institutions in our country,hypertensive heart disease research of information dissemination and resource control plays an important role.Agencies of number greater than 5 network analysis found that geographical relations are still dominate the inter-agency cooperative factors.Analysis on regional paper production distribution and cooperation at the provincial level,you can see that hypertensive heart disease in our country whether the number of output or close cooperation degree,research papers are showed obvious geographical distribution imbalance,paper production and cooperation are mainly distributed in Henan,Shandong,Jiangsu,Zhejiang,Hubei,Guangdong,Beijing,Shanghai and other minority concentrated area of medical resources,and other provincial hypertensive heart disease research strength is weak.2 The world:(1)General status of research collaboration in international hypertensive heart disease researchStudies show that international hypertensive heart disease research papers from 1990 to 2015 continues to grow.The author cooperation and agency cooperation,respectively accounted for 91.95% and 50.92% of the total number of papers,both cooperation rate for coronary heart disease research cooperation rate is higher than before[1].From the two levels of hypertensive heart disease research cooperation degree is higher,and from a multinational cooperation,cooperation degree is not high.From the point of growth,three levels of cooperation rate is increased,but the agency cooperation rate increase fastest,multinational cooperation rate,the author cooperation rate increase the slowest.To the authors,institutions,and national or regional cooperation scale analysis found that three levels of the scientific team size,are on the rise,and the increase in the number of different authors size paper trend analysis found that the author number is greater than the fastest increase in the number 7 of the paper.(2)Cooperative network analysis and the analysis of areas of cooperationFor cooperation network analysis found that 191 of the 989 team cooperative scientific research personnel.And visualization analysis found that,the author closely the author high influence authors within the network,such as Devereux,Rb,Dahlof,B,etc.However agency cooperation network analysis,Harvard University,Washington University,University of Michigan,Brigham & Women's Hospital,Mayo's a-clinic,Imperial College London and Columbia University this seven institutions without paper production,or cooperative activity are the top.Their medical research strength,in the study of global hypertensive heart disease cooperation plays a very important role.And institutional cooperation network visualization,found that agencies present obvious geographical characteristics.National or regional cooperation network analysis found that the United States,Britain,Canada,Italy,Germany,Sweden,Australia,the Netherlands and Belgium these active international cooperation of countries,and from the edge of the core,a few western developed countries in cooperation network center,and other countries or regions are on the verge of cooperation network.It indicates that economic level affects the country or region scientific research strength and scientific research cooperation.In addition from hypertensive heart disease research field analysis found that hypertensive heart disease research by more and more attention of researchers from different disciplines.Conclusions(1)The studies about hypertensive heart disease at home and abroad shows trends in different growth and cooperation(2)Production and scientific research cooperation network analysis found that the high influence authors and institutions(3)Hypertensive heart disease research production of scientific research cooperation and the paper distribution is not balanced Suggestions 1.Give full play to the leading role of the prolific institutions,to accelerate the development speed of hypertensive heart disease research.2.Strengthening the scientific research cooperation to promote coordinated development of hypertensive heart disease research.Innovation PointsInnovation point of this study is to from the perspective of scientific measurement and social network analysis of hypertensive heart disease research paper has carried on the comprehensive analysis of cooperation.the high influence authors and institutions were found.Through the database retrieval at home and abroad,found that there are no cooperation and metrology of hypertensive heart disease research paper related research.Conceptions for making further studyAlthough this study data from the database of papers at home and abroad for high blood pressure,heart disease research cooperation are analyzed,but research output also includes other aspects,such as patent,monographs,research projects,etc.To reveal the whole disease research cooperation,and other scientific research necessary to collect analysis research papers.This paper is a part and one of the research results by the national natural science foundation of " The Science and Technology Cooperation Theory Research and Empirical Characterized by Cooperation Forecast-Empirical Study of the fields of Biomedical(code: 71473154)". |
