In chapter four, molecular imprinting polymers against amino acid derivatives utilizing 2-VP+AM as combined functional monomer and trimethylolpropane trimethacrylate as tribasic cross-linker were prepared and result was compared with those with the same amino acid derivative as the imprinted molecules utilizing ethyleneglycol dimethacrylate as dibasic cross-linker. It was found that cross-link intensity of the molecular imprinting polymer is higher when TRIM was utilized and baseline separation for the imprinted molecule could be achieved. When TRIM was utilized as cross-linker more molecule is imprinted during the polymerization.

第四章采用2-乙烯基吡啶+丙烯酰胺复合功能单体，考察了三元交联剂三甲氧基丙烷三甲基丙烯酸酯烙印氨基酸衍生物的情况，并与二元交联剂乙二醇二甲基丙烯酸酯烙印相同氨基酸衍生物的情况进行了对比，发现三甲氧基丙烷三甲基丙烯酸酯交联剂在较小的用量下就可使分子烙印聚合物达到足够的交联度，实现烙印分子的基线分离。

Methods 42 cases of intractable heart failure were dividedinto 3 groups, and received intravenous infusion of nesiritide (12 cases), glycerol trinitrate (15 cases), and dobutamine (15 cases) respectively. Plasma rennin activity, aldosterone and angiotensin II were measured before and after infusion in 24h and 48h.

Research result indicated that the cooperative effect between swell and precursor is main factor for the nanoparticle loaded in Nafion, and moreover, polarity of solvent and water content in Nafion also affects the load largely. To improve away the surface concentration of CdS nanocrystal on two side of membrane for general preparation, thioacetamide was first used as a precursor instead of inorganic sulfur source(H2S and Na2S) in synthesis of CdS nanocrystal. The assembly mechanism for several sulfur source had been studied, and CdS/Nafion with the character of homogeneous disperse had been prepared, which is fit for mass transmission in photocatalitic reaction. Following the investigation of several crystallizing way, simple and reliable hydrothermal-crystallizing was found. According to this way, maximal TiO2 load in Nafion achieved 43%. Activity of TiO2/Nafion or CdS/Nafion as a photocatalyst was explored initially for disintegrating liquid contamination. Maximal decompose rate achieved 86% under condition of this research.
