Due to begin to present differentiation,IEC-6 cells grew slowly.2.This study design and compose three pairs siRNAs to RPS20 of rats,and they interference the expression of RPS20 on the aspect of mRNA and protein successfully,and prove their validity.3.After interference,IEC-6 cells cytoplasm present vacuolization,and its migration,and proliferation were suppressed,but there was no apoptosis to happen.

本课题设计并合成了3对针对大鼠RPS20的siRNAs，而且都能够有效地抑制IEC-6细胞RPS20mRNA与蛋白的表达，表明了序列的有效性；3 IEC-6细胞胞浆空泡化，并且迁移、增殖能力受到抑制，但并没有导致细胞早期凋亡的发生，该结果提示干扰RPS20可能影响IEC-6细胞的消化吸收功能和胃肠粘膜损伤修复功能，与前期收集的脾气虚证患者消化吸收功能下降、黏膜损伤修复能力下降等表现相符合。

Diltiazem is an important coronary vasodilating drug and contains two chiral centers while only the (2S, 3S)-isomer has the desired activity.

地尔硫卓是重要的心血管药物，在其分子结构中含有2个手性中心，可产生4个立体异构体，其中只有(2S， 3S)－异构体具有药理活性，因此其立体选择性合成具有很大的挑战性。

n thes paper, the oligomers with different molecular weight of monohydroxylpolyethersulfones were synthesized in solution and the optimum condition ofpolymerization was obtained; With phase transfer catalyst method,the oligomerswas obtained and transformed to monovinylpolyethersulfones macromer. Its structure was characterized with IR and 1H-NMR.

本文采用溶液法以单酚（4－氯－4'－羟基二苯砜）为原料合成了不同聚合度的单酚低聚体，得到了控制聚合度的最佳聚合条件；用相转移催化剂法成功地将单酚转化为单烯大分子单体，并用IR、1H—NMR对其结构进行了表征；测定了双键官能度均在1.90以上。

Allow the communion, as in a state of synthesis and balance, one sits in peace, and in a state of peace, earth and nature along with soul can more readily merge with one's biological consciousness.

容许通讯，因为在合成和平衡的状态中，你坐在和平里，而在和平里，地球、自然界和灵魂能更容易地与你的生物体意识融合。

We set up the angular momentum conservation model of wind accretion of Ba stars, and then derive the change equations of the orbital elements. Finally, combining the heavy element nucleosynthesis of AGB stars, we creatively calculate the heavy-element overabundances of barium stars in a self-consistent manner adopting accreting and mixing on successive occasions.

我们建立了Ba星形成的星风吸积的角动量守恒模型，推导出其轨道根数的变化方程，并结合AGB星的重元素核合成，通过逐次脉冲吸积与混合，自洽地计算出Ba星的重元素超丰。

Oil and polyol firstly hydrolyze, and then react with maleic anhydride to give semi ester, the residual maleic anhydride hydrolyzing to give maleic acid, finally are adducted with DCPD. The result of experiment shows that the synthesized resin is of perfect air drying performance and improved flexibility and anti-greening because of the use of oil, meetin...

试验结果表明，油与多元醇在210～220℃下先醇解，然后与顺酐反应形成半酯，剩余顺酐水解成顺丁烯二酸，然后与DCPD加成，合成的树脂具有优良的空干性；同时油的使用极大地提高了涂膜的柔韧性和抗绿化性，得到的树脂性能上可满足涂料用不饱和聚酯树脂的要求。

The results indicated it was very effective to increase the content of SiC whisker by ammoniating silicasol to decrease the particle size of raw powder and increase the space for SiC whisker growth, and by controlling the reaction temperature to mate the formation of SiC be compatible with the growth of SiC whisker.

工作中系统地研究了反应物料和合成工艺对SiC晶须产率和微观形貌的影响，发现氨解能促进硅溶胶的凝胶化，并细化反应物料，因而有利于SiC晶须的生成；升温速度的控制可使SiC的生成速率与SiC晶须的生长速率得到很好的适应，此为提高SiC晶须产率的有效途径。

Chlorine atoms were selectively introduced into the chlorin ring based on different reactivity between vinyl group at 3-position and 20-meso position by electrophilic addition and electrophilic substitution using hydrogen peroxide/hydrochloric acid, N-chlorosuccinimide, hydrogen chloride (or concentrated hydrochloric acid) as chlorinating reagent.
