Nowadays, modern information technology is rapidly developing; traditional novelty assessment service could not satisfy users' demands. The paper introduces an online application and management information system for medical research novelty assessment innovated of Zhuhai Health Information Center, including its background of exploration, system functions and application effects. Using this system to provide service for users could not only promote the efficiency and convenience but also provide new space of development for novelty assessment work.

Aim To investigate the effect of probucol on reverse cholesterol transport from macrophage to feces in vivo,serum lipid profiles of mice were tested before and after probucol administration for 4 weeks,and the 3H-contents in serum,liver and feces in mice were quantitated after 24 hours intraperitoneally injected macrophages which were labeled with 3H cholesterol.Methods 32 C57BL/6 mice were treated with different probucol(0,0.1%,0.5%,1% W/W)in chow diet for 4 weeks,then these mice were injected intraperitoneally with RAW264.7 macrophages(0.5 ml?mice,cells 5.0?106 with 6.2?106 cpm)which were loaded with cholesterol by incubation with acetylated LDL,labeled with 3H-cholesterol.Serum profiles were quantitated by enzymatic method;serum and liver tissues were harvested at 24th hour,feces were collected(0~24 hs),and all were analyzed for tracer counts(all were expressed as the percentage of the total injected counts per minute).Results After 4 weeks 0.1% probucol administration,the levels of total cholesterol(TC),high-density lipoprotein cholesterol(HDL-C)decreased markedly by 34.3%,52.8%,(P
