The comonomer in the copolymer by cat247 is trend to isolated. A few amount of comonomer could make the melting point remarkably decreased and maintain the crystalline at a relative high level. This catalyst can be use to produce the material with low melting point and high intensity such as packing film with low hotsealing temperature. The copolymer by cat24 is characteristic of uniform comonomer distribution and low melting temperature and crystallinity. Therefore, this catalyst could be used to produce LLDPE and POE according the comonomer content; cat246 has a strong copolymerization ability, and the resultant polymer has relatively high blockiness. If this trend is strengthened by adjustment of polymerization condition, the polymer can be used as thermal plastic elastomer with random and crystalline blocks.

由于各个催化剂所产生的聚合物各具特点，所以其潜在的工业用途不同。cat247的产物中共单体趋于孤立分布，极少的共单体即可使熔点明显降低而结晶度仍保持较高水平，有利于制备低熔点、高强度的材料（如低热封温度的包装膜等）。cat24的催化聚合产物无规程度比较高，对降低熔点和结晶度都十分有效，通过控制产物中共单体含量的多少，可以生产LLDPE和POE；cat246共聚合能力强，且产物有嵌段倾向，通过调整聚合条件强化这一倾向后，可以用来生产具有无规-结晶嵌段结构的热塑性弹性体。

A new parallel-epiphyseal cartilaginous tissue was found in the subcutaneous tissue 4 weeks after operation. The tissue was stained with HE, toluidine blue, safranine O and collagenⅡ. A large number of chondrocytes and a cartilage lacuna-like structure were observed under a microscope with no obvious inflammatory reaction around the calcium alginate and polylysine microspheres.

Thunberg Fritillary Bulb is one of the most popular Traditional Chinese herbs. Some trials in vivo and animals indicated that Peimine and Peiminine, extracted from Thunbery Fritillary Bulb, have the function of reversing MDR of two different kinds of mechanisms. They can improve the cytotoxic of ADR to cancer cells by 5～10 folds under concentration of 10% cancer cell growth inhibitory rate. Peimine and Peiminine not only feather typical character of modifier of MDR, but also differ from other moldifiers such as Calcium channel blocker, Cyclosporines in chemical structure, they belong to cevine groups alkaloid, a subgroup of C-Nor-D-homosteroid alkaloid.

浙贝母是临床常用中药，体外及动物试验证明，浙贝母中的有效活性成分贝母甲素和贝母乙素具有逆转肿瘤细胞MDR的作用，而且能逆转两种不同机制的多药耐药肿瘤细胞的耐药性，在无明显细胞毒剂量下，可使阿霉素对耐药肿瘤细胞的杀伤活性提高5-10倍，不但具备明确的多药耐药逆转剂的特征，而且在化学结构上属异甾类生物碱中的瑟文类生物碱，完全不同于钙离子拮抗剂、免疫抑制剂和其它现有的耐药逆转剂，具有作用靶点宽、化学结构独特的特点。

It was demonstrated that the actin could be polymerized into discrete filaments of tree-like branch structure, random coil filaments cluster and long filaments with different diameters in F-buffer besides random aggregates. These polymerized filaments clearly exhibited the structural polymorphism and showed obvious difference from those assembled under the regulation by actin binding proteins or phalloidin.

研究发现，actin在体外通过自装配过程除了形成无序的蛋白堆积物之外，还能够聚合形成复杂的离散结构，包括树状分支的纤维丛、无规卷曲的纤维簇以及具有不同直径的长纤维等；这些大尺度纤维复合物明显不同于在ABPs或过量F-actin稳定剂参与下形成的由单根微丝和微丝束构成的聚合结构。

The results indicated that the accumulation of Mn in the cell wall (accumulation rate as high as 36.34%) and the vacuole of the leaves (accumulation rate as high as 65.64%) might be one of the mechanisms of tolerance and hyperaccumulation of Polygonum hydropiper to Mn. Most Mn in leaves were the speciation of H2O-solubility organic salts or manganese oxalates. The content of chlorophyll a did not change under different Mn concentration treatments except that its content decreased remarkably when Mn concentration was 8000μmol/L in solutions. The membranes were not banned by Mn when its concentration was less than 5000μmol/L in solutions; Under different Mn concentrations of Mn, the content of their soluble proteins of leaves had changed at some stage. The activity of SOD and POD were gradually improved with the increasing of Mn concentration, which could eliminate activated oxygen free radical, This might be the other physiological mechanism of tolerance and hyperaccumulation of Polygonum hydropiper responding to Mn.

结果表明：锰在水蓼叶片非活性代谢部分的积累是其解毒耐锰的主要机制之一；水蓼叶片中的锰大部分以水溶性有机盐或草酸锰的形态存在；在锰浓度处理为8000μmol/L时，叶绿素a含量显著降低，而在其它处理条件下，叶绿素a无明显变化；在锰处理≤5000μmol/L时水蓼叶片的细胞膜还没有受到明显伤害；水蓼叶片的可溶性蛋白含量随锰处理浓度不同而变化，说明植物在代谢和结构上发生了调整；随锰处理浓度的增加，水蓼叶片SOD和POD活性提高，保护酶活性的提高又可清除活性氧自由基，这是水蓼耐高锰和累积锰的一种生理响应机制。
