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 analyze the changing rules of schistosomiasis endemic situation before and after reaching the crite-ria of schistosomiasis transmission controlled or transmission interrupted in Zhejiang Province,so as to provide scientific evi-dence for schistosomiasis contro1. Methods Xiuzhou District and Zhuji City were selected and investigated retrospectively to collect schistosomiasis epidemiological information 10 years before they reached the criteria of transmission controlled and the subsequent years until 2008. The database of retrospective investigation was established for analyzing the trends and rules of changes of Oncomelania hupensis snail status and schistosome infection status of cattle and human. Results The snail status and schistosome infection kept a steady declining before reaching the criteria of transmission controlled ,and there were positive correlations between the area of living snails and the infection rates of human and animal in two places(rhuman=0.764,P<0.01, rcatl e=0.709,P<0.01;rhuma=0.775,P<0.01,rcatl e=0.676,P<0.01);No local infection person and animal except residual snails, and found 7 cases of imported infection source were found after reaching the transmission interruption. Conclusion The epi-demic status of schistosomiasis in zhejiang is stable after reaching the criteria of transmission interruption ,and residual snail are easy to re-found and spread under some certain conditions,and some imported cases were found sometimes,which may in-crease the risks for re - emergence of schistosomiasis. The integrated solidification strategy with emphasis on control of residu-al snails and imported cases should be taken in the areas of transmission interruption in the future.
