乙肝病毒基因上一个新的维甲素受体反应元件的发现

在对人乙肝病毒ＡＤＲ－１进行计算机序列检索时，发现在Ｂａｍ ＨＩ和ＨｉｎｃⅡ酶切位点内存在一保守的维甲素受体反应元件序列。用构建好的包含这一片段的乙肝病毒基因亚克隆ｐＢａｍＨＩ－ＨｉｎｃⅡ－ＣＡＴ２与人维甲素Ａ受体ｈＲＡＲα或人维甲素Ｘ受体ｈＲＸＲα共转染人特异性肝癌细胞ＨｅｐＧ２，通过相应配体ＡＴＲＡ或９－ｃｉｓＲＡ的刺激，使细胞内氯霉素乙酰基转移酶活力较不加配体刺激的对照细胞明显增强。为了排除     

二氮杂萘联苯型聚芳醚聚合机理的探讨

以自制的类双酚化合物与二卤单体反应，以及类双酚与对氯苯腈反应合成了３种模型化合物；通过对模型化合物的结构分析，证实了该新型类双酚单体中Ｎ－Ｈ参与亲核取代反应，形成了Ｃ－Ｎ相连而非Ｃ－Ｏ相连结构，进而提出了类双酚单体经亲核取代反应合成聚芳醚的反应机理。     

秦巴山区宁强试验点弱智儿童维生素A营养状况分析

以秦巴山区宁强试验点４９名弱智儿童为试验组，以当地７４名智力正常儿童为对照组，采用荧光分析法测定了两组儿童的血清ＶｉｔＡ水平。结果表明：弱智儿童与对照组儿童血清ＶｉｔＡ水平无显著差异（Ｐ＞０．００５），试验组儿童中严重缺乏维生素Ａ发病率低，但亚临床型维生素Ａ缺乏发病率高，分别为６３．３％和６８．９％。其中，０岁～６岁儿童发病率显著高于７岁～１４岁儿童（Ｐ＜０．００５），从而提示贫困山区弱智儿童中存在严重的亚临床型维生素Ａ缺乏。     

有机酸萃取稀土元素钕的机理研究

Modeling of Solid-state Polycondensation of Poly (ethylene terephthalate)

A mathematical model has been developed to handle the reactions in Poly(ethylene terephthalate) (PET) undergoing polycondensation reactions in the solid state. The effect of temperature on chain mobility was considered to estimate the rate constants of chemical reactions. The polymer crystalline fraction is modeled as containing only repeat units, thus concentrating end groups and conden-sates in the amorphous fraction. This model is compared with PET reaction data with good results.     

Polymerization kinetics and stabilization mechanism of the monodisperse PMMA microspheres

The effects of the concentration of monomer, crosslinking agent, initiator, stabilizer, and the polarity of medium on the polymerization kinetics were investigated. The results show that the rate of polymerization (Rp) and conversion increased with the increase of monomer concentration from 8% to 15% (total mass); the water content in dispersion medium and the initiator 2, 2′ -azobis (isobutyronitrile) (AIBN) concentration increased as well. Rp and conversion decreases with the increase of PVP when it is low, while it increases when it is high. Moreover, PVP plays an important role in microsphere stabilization. The stabilization mechanism was investigated primarily, which involves both adsorbing mechanism and graft mechanism. Within a certain range of crosslinking degree, Rp and conversion increased with the increase of the crosslinker concentration. The effect can be ignored when crosslinker concentration is above 0.3 % (total mass), and the reason was that the monomer can hardly be diffused into the microsphere phase with a certain degree of crosslinking.
