ABSTRACT
objective:To analyze the contributed papers and publications in the first half year of 2020 from Shanghai Journal of Preventive Medicine， especially the COVID-19 papers， to provide basis for the academic journals to win out during the public hot points. Methods:All the papers contributed in the first half year of 2020 from Shanghai Journal of Preventive Medicine， were collected to analyze the sources parameters， editing parameters. All published papers were collected to analyze the sources parameters， editing parameters and their usages （downloads and citations）. Results:There were 450 papers contributed in the first half year of 2020， 129 papers were accepted accounting for 28.67%. Among them， 116 papers were COVID-19 papers accounting for 25.78%， and 32 papers were accepted accounting for 24.81%. the March was the highest month of contribution， also for COVID-19 papers. Many academic domains such as infectious disease， women and children health， clinic science， chronic disease， social medicine， public hygiene and others were predominated among those papers. COVID-19 papers dominated in domains of infectious disease and social medicine. According to the non-COVID-19 papers， the COVID-19 papers had higher numbers of peer reviewers， lower days for back improvement， lower days for refusals or acceptance， also had lower copy percentages by plagiarism check （all P<0.05）. there were 106 papers published in the first half year of 2020. Published COVID-19 papers had higher number of authors， higher numbers of references in term of governments reports， foreign references and less than 5 years references （all P<0.05）. Those published COVID-19 papers had better usages than those no-COVID-19 papers， adjusted downloads were 2 077.37/year vs 111.53/year， adjusted citations were 12.99/year vs 0.49/year. It was obvious that the published COVID-19 papers had very excellent social influences and academic influences （P<0.001）.

ABSTRACT
Media convergence is the combination and convergence of every element of media in forms of breakdown of traditional classification, formats and distribution etc. It means the blending of its contents, consumers and operations in full and a new media was developed named as new media. The paper tries to explore the media convergence by starting from the paper-printed media, especially from the scientific journals. It is obvious that the basement is the electronization of media, comprehensive use of multi-technology is the fundamental tools, and it made the results of the inevitability of deep changes in term of thoughts, mindset and managerial principles as well. At the same time, the adverse effect of media convergence consequently coming from the freedom and openness of media convergence will be considered and avoided, so the surveillance of administrative functions and technicals should be adopted or developed accordingly.
ABSTRACT
[ Objective ] To explore the related factors of colorectal polyps. [ Methods ] Participants were divided into polyps group and control group according to colonoscopy.The possible risk factors were investigated by questionnaire.Logistic regression analysis was conducted in order to explore the related factors of colorectal polyps. [ Results] A total of 252 participants (154 in polyps group, 98 in control group) were enrolled in the current study.Multivariate Logistic regression analysis showed that those with higher odds ratio of colorectal polyps were among male ( OR: 2.65, 95% CI: 1.17 -6.00) and obesity(OR:4.80,95%CI:1.16 -9.94), among those with family history of colorectal polyps ( OR:10.19, 95%CI:1.19-17.26), and those with high proportion of fat intake(OR:3.24, 95%CI:1.46-7.20). [ Conclusion] Male, obesity, family history of colorectal polyps and high proportion of fat intake are the related factors of colorectal polyps. And investigation by related factors questionnaire facilitates the targeted screening of colorectal tumors.
