On the base of Pearson correlation coefficient indicate that the connection between IBI and CQHEI is higher than IBI and ISC of Juoshuei river basin. To the section of the upper and middle reaches, we suggest choosing simple and convenient SIAM to be the standard for environment in the future. But due to the type of ecosystem has a tendency to estuary ecosystem at the lower reach of Juoshuei river basin, SIAM is more unsuitable for evaluating at the reach. The correlation between each index is not notable, so we suggest seeking other assessment method as comparative environmental standards.

由指标相关性讨论可知栖地品质与生物完整性相关性较高(r=0.649)，水质状态与生物完整性相关性则较低(r=0.267)，对於中上游河段部分，建议日后进行河川生态环境调查时可选择简便易用的SIAM模式做为标准；下游近海河段则因河川型态渐转变为河口生态系的型态，故适用於溪流生态系的SIAM在适用性上较差，各指标间相关性并不显著，建议可寻求其他评估模式做为环境品质的判断标准。

Theurinary IL-6 level positively correlated with density of glomerular matrix membrane, global sclerosis, fiber or fibrocellular crescents and interstitial fibrosis (p. 05). According to the degree of density of glomerular matrix membrane and interstitial fibrosis, urinary Col-IV level had better correlation than urinary TGF-betal and IL-6 levels.In IgAN, Col-IV showed increased expression in diseased renal tissue whereas the site of expression of TGF-betal was mainly localized within the cytoplasm of tubular epithelial cells. Interstial expressionwas also present but glomerular TGF-betal expression was found only in patients with heavy mesangial proliferation. There was a significant correlation between glomerular positivity for Col-IV and severity of histological damage. There was also a significant correlation between positivity for TGF-betal and Col-IV in the tubular epithelial and interstitial lesions. In contrast, there was no ralationship between glomerular positivity for TGF-betal and severity of histological damage.The urinary TGF-betal level paralleled tubular TGF-betal expression.

The results show that 42.86% topsoil samples are polluted by Cadmium, soil synthesis pollution index is moderate, Cadmium pollution degree of topsoil correlate with the environment of sampling sites. The results also show that exchangeable Cd, carbonate-bound Cd, organic-bound Cd and residual Cd are found in all soil samples except for Fe-Mn oxide-bound Cd. Furthermore, the concentration of exchangeable Cd and carbonate-bound Cd, both which have high biological validity, is high. Humus has a certain correlation with exchangeable Cd, organic-bound Cd and residual Cd, and has no obvious correlation with other chemical speciations. Any chemical speciation of Cd has no obvious correlation with pH and total Fe of soil samples. Cadmium in topsoil can be eluviated by acid solution, the quantity of Cadmium eluviated by redistilled water is little. With the rise of pH of eluviating solution, eluviated Cadmium quantity decrease. For the same soil sample, the lower pH value of eluviating solution is, the more fast the Cadmium is eluviated, and the more thequantity of Cadmium is eluviated.
