Objective To explore the characteristics and data collection sources of featured literature databases in universities/colleges in Yunnan in order to provide evidence for building featured literature databases. Methods Key information about three types of featured literature databases was retrieved online, which included those being constructed jointly by some universities or colleges in Yunnan, owned by universities or colleges in Yunnan, and already in use in China Academic Library and Information System ( CALIS) , respectively. Comparison was performed among these featured literature databases in regard to data characteristics and collection sources. Results Among all the featured databases being constructed, 58.8% were based on literature on local resources, 17.6% on disciplines and specialties, and 11.8% on library literature. In-use featured databases in Yunnan were mainly based on local resources and disciplines, and the data were collected within their own organizations or through multi-sources. The featured databases in CALIS were of local resources, disciplines, and people, while their data were collected mainly within their own organizations, through other organizations and multi-sources. Conclusion Yunnan featured databases are of unique characteristics, but more should be done to define Yunnan style data, while it is necessary to collect data from a wider range of sources.

【Objective】 To investigate the hepatitis E virus(HEV) infection among voluntary blood donors in Liuzhou, Guangxi. 【Methods】 Qualified blood donations in Liuzhou from October to November 2019 were tested for anti-HEV IgG and IgM and.HEV antigen. HEV RNA test was performed on samples positive for HEV antigen and/or anti-HEV IgM. and the test results were analyzed statistically. 【Results】 The seroprevalence rates of HEV antigen and anti-HEV IgG and IgM among 5 751 qualified donations were 0, 26.03% (1497/5 751), and 1.67% (96/5 751), respectively.None of the 91 anti-HEV IgM positive samples was positive for HEV RNA, whereas 60.41% of anti-HEV IgM positive samples were anti-HEV IgG positive. The HEV antibody prevalence varied significantly by gender, age, and nationality (P<0.05). 【Conclusion】 The prevalence of anti-HEV IgG / IgM among blood donors in Liuzhou was higher than that in other domestic regions. Significant increase in HEV antibody prevalence was observed among ethnic minorities, such as Miao and Dong, and age group of more than 45 years.Follow-up studies with larger sample size could be conducted to estimate potential risks of HEV transmission by blood transfusion, which may provide references for selective screening of HEV infection marker among high-endemic population.
