Results:①The amount of human colon carcinoma cell line SW480 treated by quercetin decreased. The morphology of partial SW480 cells was shrunk volume, integrated cell membrane, condensed cytoplasm, pyknotic chromatin, nuclear fragmentation. Apoptotic Corpuscles were found by electron microscope.②MTT colorimetric assay showed quercetin inhibited the growth of human colon carcinoma cell line SW480 in a time- and dose-dependent manner when the concentration of quercetin was 30、60、90μmol/L.③Flow cytometry analysis showed the cell cycle of SW480 cell was restricted in G1/S. G0/G1 phase rate increased and S phase rate decreased with increasing concentration of quercetin and time lasting.④ Zymogram analysis assay showed the secretion of matrix metalloproteinases in human colon carcinoma cell line SW480 treated by quercetin decreased. With increasing concentration of quercetin, the secretion of MMP-2 and MMP-9 decreased.⑤Immunohistochemistry method demonstrated the position expression of Cathepsin-D in SW480 cell was suppressed by quercetin in a time- and dose-dependent manner.

Then the author analyzes empirically China's terms of trade from 1981,and the causes of the change in the net barter terms of trade by means of regression analysis ,which can be quantitied.we get the results that China's net barter terms of trade had a declining trend while its income terms and factorial terms of trade had been improved,and the net barter terms of trade positively correlates with actual tariff rate,exchange rate and negatively correlates with GDP,besides,the factors which can not be quantitied such as pure price fighting,inappropiate tariff sytem,foreign-invested enterprises's tranfer pricing and region trade agreement also lead to the above trend of China's net barter terms of trade,and the change in China's net barter terms of trade had a neglect impact on international trade benefit.

得出中国价格贸易条件总体上存在下降趋势，收入、要素条件呈现改善的趋势；实际关税率、汇率与价格贸易条件存在正相关关系，GDP指数与其负相关。出口企业恶性价格竞争、不合理的关税体制、外资企业的转移定价、区域贸易集团是造成中国价格贸易条件下降的非量化因素。此外，本文分析了1981-2004年价格贸易条件变动导致的中国国际贸易利益变化，发现价格贸易条件变动对中国国际贸易利益产生了一定的负面影响。最后，本文在分析中国价格贸易条件变动环境的基础上，认为中国工业化阶段不高、贸易限制性政策实施空间的减小、&合成谬误&现象及知识经济时代的到来会在一定时期内对价格贸易条件变动不利。
