ObjectivesTo survey the domestic research situation of evidence-based education through visual studies. To summarize the utilization of education evidence in China and promote the process of evidence-based practice concepts and methods application in social science fields, so as to facilitate the domestic evidence-based research towards more scientific and practical. Methods WanFang Data and CNKI databases were searched to collect evidence-based education literatures from inception to December, 2017. Tableau and UCINET software were used to conduct visual and co-word analysis of study types, regions, staff, time, foundation/government support and key words. The social evidence based research situation was sketched. Results A total of 54 literatures were included. Beijing and Guangdong province published the most literatures, followed by Zhejiang province and Tianjin municipality. The quantity of literatures published in 2014 reached the peak of 11 articles, followed by 2016 and 2017, and relatively few in remaining years. We found that " evidence-based pedagogy” owned the highest frequency through building core keywords matrix. Conclusions Evidence-based education in China is still at an early stage. Introduction and promotion is currently the main content. There exists problems remaining in the development of evidence-based education, for instance disjointedness of theory and practice, regional unbalance, and deficiency of original-research. It is still a long way to go.
ObjectiveThe purpose of this study is to apply the method of CO-word analysis to the evidence-based study of the diagnosis and treatment of Budd-Chiari syndrome (BCS), to understand the trend of BCS research in China and to explore the hot spots of BCS in recent years, and to provide new evidence-based data for the clinical practice and experimental research of BCS in China.MethodsIn the Wanfang database, CNKI, and VIP retrieval platform, " Budd-Chiari syndrome” was used as the key word or title. According to the publication time, it was divided into before 1998 (study group 1), 1999–2008 (study group 2), and 2009–2018 years (study group 3). The relationship matrix was established by using the Netdraw tool in Ucinet6.0, and the common words were plotted with the Netdraw tool. The word relation network was used to get the analysis chart of the relation of the word.ResultsThis study found that, Budd-Chiari syndrome, inferior vena cava, hepatic vein, inferior vena cava obstruction, and syndrome were the most frequently used keywords in the study group 1. Budd-Chiari syndrome, inferior vena cava, hepatic venous, interventional therapy, and patients were the most frequent keywords in the study group 2. In the study group 3, Budd-Chiari syndrome, interventional therapy, inferior vena cava, hepatic vein, and patient were the most frequent keywords.ConclusionsHepatic vein type and inferior vena cava type have became a research hotspot in recent years, and the thrombosis mechanism is one of the directions for domestic scholars to study the etiology of BCS. The diagnosis and classification of BCS depend on color doppler ultrasound technology. Many studies focus on the differential diagnosis of BCS and cirrhosis.
