Part Two: The effect of fruit extract on CRL-2606 production of PGE2 Effect of anthocyanin rich fruit extracts on endothelial cells'PGE2 production Epidemical experiment shows that phenolics in fruits and vegetables may prevent the occurrence of chronicle cardiovascular heart disease. To investigate the activity of fruit extracts on artery blood vessel cells, we chose CRL-2606 cell line, a normal iliac artery endothelia cells. Using indomethacin as control, we investigate the effect of blueberry extracts, blackcurrant extracts, chokeberry extracts, cyanidin3-glucoside, and malvidin3-glucoside on the PGE2 production of CRL-2606 cells.

第二部分水果提取物对人体细胞系CRL-2606产生PGE2的影响水果提取物对血管内皮细胞释放PGE2的影响流行病学调查表明，蔬菜水果中的多酚类物质具有预防慢性心血管疾病的作用，为研究水果提取物对血管细胞的作用，我们选择回肠动脉内皮细胞CRL-2606细胞系作为研究对象，以indomethacin为对照，研究了blueberry，blackcurrant，chokeberry提取物及cyanidin3-glucoside，和malvidin3-glucoside对血管内皮细胞释放PGE2的影响。

Firstly, we consider SIQR epidemical models with continuous and pulse vaccinations; the reproduction numbers have been obtained for those models; by using Dulac function, we prove the global stabilities of equilibrium of SIQR model with continuous vaccination. In the SIQR epidemical models with pulse vaccinations, we have also discussed the existence of the infection-free periodic solution, the global stabilities of the infection-free periodic solutions, and the effectiveness of pulse vaccination and continuous vaccination policies has been compared for the two models.
