In this thesis, shikonin, cryptotanshinone and 5-fluorouracil (5-FU) were selected as the objects for several aspect studies: In Chaper 2, the electrochemical behavior of shikonin was investigated by cyclic voltammetry, linear sweep voltammetry, chronocoulometry and bulk electrolysis with coulometry on a glassy carbon electrode. Triple strand DNA modified electrode was preparated and used to investigate the interaction of shikonin with DNA. It was found that it is hydroquinone of shikonin to embed in DNA and interacted with guanine and adenine of DNA.

本论文以紫草素、隐丹参酮和5-氟尿嘧啶三种抗癌药物为研究对象，做了以下几个方面的工作：在论文的第二章，我们研究了紫草素的电化学基本性质，初步探讨了三链DNA 修饰电极的制备，并利用该修饰电极研究紫草素与DNA 的相互作用，得出主要是紫草素的氢醌与DNA 的G、A 碱基间发生嵌插作用的结论。

Mechanical strains also regulated the protein and mRNA expression of several differentiation markers, as well as the activation of extracellular signal-regulated kinases, p38 MAP kinase and protein kinase B in a frequency-dependent manner. Furthermore, the inhibition of p38 pathway could block the strain-frequency induced the phenotype modulation of VSMCs, neither ERKs nor Akt. Frequency of mechanical strain, not conditioned medium, regulated the phenotype of VSMCs in a frequency-dependent manner. Rho-GDI alpha was suppressed by the mechanical strain at 1Hz.

采用免疫细胞化学法检测VSMCs形态和排列的变化；RT-PCR和Western blotting检测表型标志分子α-肌动蛋白、肌球蛋白重链(SM1/2)、肌动蛋白相关蛋白SM22α和调宁蛋白(h1-calponin)的mRNA和蛋白水平的变化；抑制剂或RNA干扰阻断可能的信号调节分子的活性或表达，包括p38、细胞外信号调节激酶1/(2extracellular signal-regulated kinases， ERK1/2)、蛋白激酶B和Rho-鸟苷酸解离抑制因子(Rho-guanine nucleotide dissociation inhibitor， Rho-GDI alpha)，研究了不同频率张应变对VSMCs表型转化的影响及其调节机制。

The repair of alkylation damage to the O6-position of guanine is performed by O6-alkylguanine-DNAalkyltransferase, whose expression is considerable variated among individuals.

MGMT 是人体内唯一能将 NNK 所致 O6-鸟嘌呤甲基加合物从 DNA 上移除，进行损伤修复的 DR 蛋白，但其表达在不同的个体中存在显著的差异。

Based on density functional theory and electronegativity equalization principle,applying an atom-bond electronegativity equalization σπ model,using a separated program,we calculated the charge distributions and dipole moments of guanine tautomers.

以密度泛函和电负性均衡原理为基础发展的原子-键电负性均衡方法的σπ模型。并结合自编程序，计算了鸟嘌呤五种异构体的电荷分布和偶极矩，计算结果表明，所计算出的电荷分布可以和从头算结果很好地关联。所计算的偶极矩与其它从头计算方法和力场方法相比总体趋势相同，进一步说明了ABEEMσπ模型的合理性

Any of various compounds consisting of a sugar, usually ribose or deoxyribose, and a purine or pyrimidine base, especially a compound obtained by hydrolysis of a nucleic acid, such as adenosine or guanine.

核苷由糖，通常是核糖或脱氧核糖和嘌呤或嘧啶基组成的化合物，尤指从核酸水解中获得的化合物，如腺嘌呤核苷或鸟嘌呤

Thus, nucleotides in DNA or RNA are typically called 'bases'; consequently they are commonly referred to simply by their purine or pyrimidine original base components adenine, cytosine, guanine, thymine.

因此，核苷酸的DNA或RNA通常是所谓的'基地'；因此，他们通常被称为只要他们嘌呤或嘧啶在原有的基础上组成部分腺嘌呤，胞嘧啶，鸟嘌呤，胸腺嘧啶。

Nucleosides are compounds composed of a purine or pyrimidine base (usually adenine, cytosine, guanine, thymine, uracil) linked to either a ribose or a deoxyribose sugar.

核苷是由嘌呤基，嘧啶基(通常是腺嘌呤，胞嘧啶，鸟嘌呤，胸腺嘧啶，尿嘧啶)与核糖或脱氧核糖相连而组成的化合物。
