利用RNA干扰的方法抑制人外周血单个核细胞(PBMC)中Itk基因的表达,探讨其抑制Itk后对人PBMC增殖和炎症性相关细胞因子产生的影响。设计针对Itk基因的siRNA序列,与外源表达Itk的pEGFP-C1-hItk质粒共转染至HeLa细胞,筛选出有效的干扰序列;利用电转染的方法将有抑制Itk作用的siRNA转染至人PBMC,检测Itk抑制状态,同时观察细胞增殖率及炎症性细胞因子产生水平的变化。实验表明,Itk-siRNA有效地抑制了Itk蛋白的表达;Itk受到抑制后细胞增殖率明显低于对照组(P<0.05);几种重要炎性细胞因子IL-2、IFN-γ、IL-5、IL-10和IL-4产生水平下降。实验验证了Itk蛋白在人PBMC增殖和炎性细胞因子产生方面的重要作用。

The hydroxylation reaction mechanism of nitrosodimethylamine（NDMA） by oxygen atom was theoretically investigated at the B3LYP/6-31G＊＊ level. It has been found that the path of the oxydation of the C―H bond is easier than the path involving a Singlet/Triplet crossing. The study of the potential surface shows that both solvent effect at B3LYP/6-31G＊＊ level and different method at more credible MP2/6-311G＊＊ level in the gas phase have no effect on the hydroxylation reaction mechanism. The oxidation hydroxylation process of NDMA by O is exothermic reaction and easy to occur.

地球内部广泛存在着差应力,这些外在因素的存在影响着矿物的性质,而矿物的电学性质与结构相变息息相关.为了更加了解地球内部结构与动力学过程,采用第一性原理方法,在等效平衡压0~10 GPa范围内计算地球内部浅层矿物石膏在静水压和非静水压条件下的电学性质.计算结果表明:静水压和非静水压条件下无水石膏的密度和带隙变化基本一致,但二水石膏的密度和带隙在非静水压为6 GPa附近发生突变,这可能是由于非静水压环境使晶体结构更容易发生畸变,更有利于水分子氢键网络的重新排列和CaSO_(4)层间结构的塌缩,因此非静水压下可能更加有利于二水石膏在高温高压下的脱水反应.这对理解地幔中矿物的脱水和储水产生重大的影响,为理解地幔中矿物的脱氢和储水提供理论依据.
