Global research status of gastroenterology and hepatology: A bibliometrics study

Background:There are no reports on global research status of gastroenterology and hepatology (GI). This study was conducted to reveal the current global research status and trends in GI.Methods:Articles published during 2009 to 2018 in international GI journals were retrieved from the PubMed database. The top 20 countries by output were determined. The gross domestic product (GDP) of each country was also retrieved to figure out the correlation between outputs in GI and economy. The 5 highest-ranking countries were compared in the number of total articles, articles per capita, articles published in top journals, the accumulated impact factor (IF), and average IF. Total articles and articles per capita of the 5 countries were conducted time-trend analysis. The frequently-used terms in titles and abstracts of articles published in 2009 and 2018 were retrieved to conduct co-occurrence analysis to figure out the change of research highlights in GI.Results:A total of 120,267 articles were included, of which 116,485 articles were from 20 highest-output countries. There was a positive correlation between output and GDP (r = 0.921, P < .001). The USA, Japan, China, Italy, and the UK were the 5 highest-ranking countries. The USA was the largest contributor with 26,215 articles, accounting for 17.4% of the total, but with no significant increasing trend (P = .122). Other 4 countries all showed increasing trends (all P < .001). For articles per capita, Italy ranked 1st among the 5 countries with 1591.0 articles per 10 million. The USA showed a decreasing trend (P = .026), other 4 countries all showed increasing trends (all P < .001). The UK had the highest average IF (6.685). For change of research highlights, it is more inclined to research of endoscopy, inflammatory bowel diseases, and nonalcoholic fatty liver disease.Conclusion:It is delightful that the global research output in GI field would be continuingly increased as the major highest-output countries showed increasing trends. However, the developing countries fell behind both in quantity and quality when compared with developed countries.

What does SCI mean to a doctor in China？

In China, to be an excellent doctor means to publish Science Citation Index （SCI） paper as much as possible. The scientific evaluation system based on the number of SCI publications becomes the only criteria for ranking position of Chinese doctors. Who can save them from the slavery of SCI？

生物医学学术论文投稿要素

科学论文的功能是把新的研究方法、新的研究成果或新的研究理论介绍给读者。具有广泛读者的尤其属于《科学引文索引》(Science Citation Index:SCI)类专业杂志是研究工作者所争取的发表场所。除研究内容创新和具有应用价值外,扎实的写作基础和科学语言(如英文)的表达是取得成功发表的关键。本文介绍怎样准备科学论文的书写和投稿要素,希望有助于提高论文的书写质量,从而提高国际专业杂志接收刊登的收稿率。     

Impact factors: Use and abuse in biomedical research

Impact factors are increasingly being used as measures in the process of academic evaluation; however, the pitfalls associated with such use of impact factors are not always appreciated. Impact factors have limited use as criteria in determining the quality of scientific research. Classical anatomists may be actively discriminated against if journal impact factors are used as measures of scientific merit in comparison with colleagues in more popular or faster‐moving disciplines such as molecular biology. Research evaluation based on citation rates and journal impact factors is inappropriate, unfair, and an increasing source of frustration. Anat. Rec.
