大肠癌与溃疡性结肠炎患者血清微量元素测定

用ＩＣＰ－ＡＥＳ方法，对３０例大肠癌，２６例溃疡性结肠炎进行血清钼，锌，铬铁，铜，锰，铅，铝，硒，铋，钡，钛，钴，钒等微量元素测定，并与２０例健康者对照。结果显示大肠癌组血清钼，锌，铬，低于对照组钼，锌，铬，Ｐ分别〈０．０１，〈０．０５，〈０．０５；溃疡性结肠炎组钼低于对照组，Ｐ〈０．０５。提示微量元素代谢异常可能直接影响酶系统，使自由基失控，体内促氧化和抗氧化平衡失调，促使肿瘤的发生。

Preparation and adsorption properties of PAA-grafted cellulose adsorbent for low-density lipoprotein from human plasma

A new low-density lipoprotein (LDL) adsorbent with good adsorption performance has been obtained by use of a simple preparation procedure. Graft copolymerization of acrylic acid (AA) on to macroporous cellulose beads was performed with cerium ammonium nitrate (CAN) as a redox initiator. The effects of initiator concentration, monomer concentration, and reaction time on grafting were examined. In adsorption tests, several factors affecting adsorption of lipoproteins were investigated in detail. In-vitro study showed that this adsorbent could remove total cholesterol (TC), low-density lipoprotein-cholesterol (LDL-C), and triglyceride (TG) at levels of 5.55, 4.46, and 2.48 mg g⁻¹, respectively, from human plasma without substantially affecting high-density lipoprotein-cholesterol (HDL-C) and total proteins (TP). The adsorbent prepared in this work might be further studied for potential clinical application.     

A Modified Chitosan Adsorbent for Selective Removal of Low Density Lipoprotein

A modified chitosan adsorbent was synthesized through a simple preparation procedure,and it demonstrated good adsorption performance for selective removal of low density lipoprotein in human plasma. Phase inversion technique was employed to form chitosan beads, to which epoxy groups were then introduced by reacting with ethyleneglycol diglycidylether, and tryptophan was subsequently coupled to the epoxy-activated beads.

含牛磺酸交联聚乙烯醇的合成及其对甘油三脂吸附性能*

以牛磺酸修饰交联聚乙烯醇凝胶合成了吸附剂。吸附实验结果表明：该类吸附剂对血清中甘油三脂具有良好的吸附效果,而对血清中总蛋白的吸附性能相对较弱。它们对甘油三脂的吸附性能着吸附剂上功能基含量的增加而加强,但随着载体的交联度的提高而降低。血清中致病因子的浓度影响吸附性能。

一种新型低密度脂蛋白吸附剂的制备

研究表明,人体血浆中低密度脂蛋白(LDL)的含量过高会引起动脉硬化,进而诱发各种心脑血管疾病^[1].近年来,采用血液净化吸附剂去除LDL受到了广泛的关注^[2～10].目前临床上使用的吸附剂主要有固载LDL抗体的琼脂糖吸附剂及固载肝素或磺化葡聚糖的纤维素吸附剂,它们虽有较好的吸附效果,但由于存在配基昂贵、吸附剂成本高及机械强度差等问题,这些吸附剂的应用受到了很大的限制.本文以具有良好机械强度和血液相容性的聚乙烯醇(PVA)大孔珠状树脂为载体,以廉价易得的吲哚-3-乙酸(IAA)为配基,分别以不同长度的多胺为悬臂,制备了一种新型LDL吸附剂,并初步考察了其对LDL的吸附性能.     

Purification of transferrin by magnetic immunoaffinity beads

Immunoaffinity adsorbent for transferrin (Tf) purification was prepared by immobilizing anti‐transferrin (Anti‐Tf) antibody on magnetic monosizepoly(glycidyl methacrylate) beads, which were synthesized by dispersion polymerization technique in the presence of Fe₃O₄nanopowder and obtained with an average size of 2.0 μm. The magnetic poly(glycidyl methacrylate) (mPGMA) beads were characterized by Fourier transform infrared spectroscopy, swelling tests, scanning electron microscopy, electron spin resonance spectroscopy, thermogravimetric analysis and zeta sizing analysis. The density and swelling ratio of the beads were 1.08 g/cm³ and 52%, respectively. Anti‐Tf molecules were covalently coupled through epoxy groups of mPGMA. Optimum binding of anti‐Tf was 2.0 mg/g. Optimum Tf binding from aqueous Tf solutions was determined as 1.65 mg/g at pH 6.0 and initial Tf concentration of 1.0 mg/mL. There was no remarkable loss in the Tf adsorption capacity of immunoaffinity beads after five adsorption–desorption cycles. Tf adsorption from artificial plasma was also investigated and the purity of the Tf molecules was shown with gel electrophoresis studies.
