AIM: To investigate the effects of four different ingredients of zedoary (Curcuma aromatica oil, Curcumol,β-elemence, and Curcumin) on the gene expressions of hepatic stellate cells (HSCs), and to explore the molecular mechanism of zedoary against hepatic fibrosis at gene network ***: We detected the mRNA sequences of 50 liver fibrosis-related genes in GenBank and designed oligonucleotide probes. We synthesized oligonucleotides with PE8909 DNA synthesizing instrument, and carried out oligonucleotide microarray with OGR-04 dropping instrument and aldehyded glass chip. Cultured HSC-T6cells were treated with different concentrations of Colchicine,Curcuma aromatica oil, Curcumol, β-elemence, and Curcumin. According to the experiment of cell toxicity,we took the appropriate concentrations of medicines that resulted in over 50% of cell survival as experiment concentrations. We collected the cells at 1, 6, 12, and 24 h, and extracted total RNA with TRIzol reagent, then labeled cDNAs with Cy3-dUTP and Cy5-dUTP. These labeled cDNAs were hybridized to an oligonucleotide microarray which was washed several times and scanned by scanner GenePix 4000B. Different gene expressions of HSC-T6 cells were analyzed by ImaGene 4.2 ***: After HSC-T6 cells were cultured in a medium containing 6.25 μg/mL Colchicine for 12 h, expression of TIMP-1 decreased 2.2-folds. After HSC-T6 cells were cultured in a medium containing 78.125 μg/mL of Curcuma aromatica oil for 24 h, the expression of TIMP-2and IL-6 decreased 2.3- and 2.2-folds, ***, after HSC-T6 cells were cultured in a medium containing 1.5625 μg/mL of Curcumol for 12 h, the expression of TGFβ1 and P450a decreased 2.3- and 2.1-folds, ***: Our results may show the possible molecular mechanism of Curcuma aromatica oil and Curcumol against hepatic fibrosis.

使用Bundy和Dunn发展起来的带有烧结金刚石砧的Drickamer型高压装置,用固定点测压法标定实验压力,在室温及0～43GPa的压力范围内测量了稀土金属中Pr、Nd、Sm,Gd、Tb、Dy、Ho、Tm、Lu和Yb的电阻随压力的变化。在各稀土元素的电阻随压力变化的曲线上,观测到了若干“凸起”和斜率突变点,根据Jayaraman提出的三价稀土在压力作用下的相变顺序,得到了这些突(凸)变点分别对应着hcp→Sm-type→dhcp→fcc相变顺序中的某一类型的相变压力。此外还观测到了Pr、Gd、Tb的fcc相随着压力再增高而发生的相变,根据已报导的关于Pr的工作,推测Gd和Tb的这一相变应为fcc→dfcc相变,它们分别发生在22.0和24.5Gpa。在本工作所得结果基础上对Johansson的三阶稀土总相图进行了修正

地震勘探工作中地震采集系统的设计是最为重要的环节,影响到后期资料处理的质量,本文在分析观测系统采集质量与各个参数设置的关系的基础上,提出了基于观测系统综合质量因子评价方法,即接收道数、炮线距、接收线距和接收线数等四个采集参数,给出了观测系统采集质量随四参数变化的关系式。我们根据实际的野外资料利用观测系统综合质量因子评价方法,分析了观测系统质量与四参数的变化关系,结果显示炮线距对观测系统质量影响最大,而接收线距的增大可以适当的提高观测系统质量,接收道数增加可以提高观测系统质量。并利用正演和偏移方法生成不同采集参数的叠前偏移剖面,对比结果表明用本文方法分析结果和偏移剖面结果是一致的,不同的采集参数对浅层和深层同相轴质量有不同的影响,因此生产中我们应根据目的层深度选择合理的采集参数,可结合质量因子评价方法分析优选采集参数。

As revealed from recent drilling and organic geochemical testing and research, a series of lacustrine high-grade hydrocarbon source rocks was discovered in the upper section of the Chang 9 oil reservoir member of upper Triassic in Ordos Basin. The hydrocarbon source rocks show average TOC content as high as 5.03%, average bitumen "A" content as high as 0.8603%, and good quality organic precursors, which are of the sapropelic type mainly derived from lower aquatic plants and have reached the thermal evolution stage featured by oil-producing climax. Generally the lacustrine high-grade hydrocarbon source rocks were developed in local depressions of a lake basin, and the Chang 91 member was particularly formed in a depositional environment characterized by fresh water to weakly saline water, weakly oxidizing to weakly reducing setting and semi-deep lake facies, as was demonstrated by a variety of organic to inorganic geochemical parameters. As a result, high productivity constitutes the principal controlling force for generation of this series of high-grade hydrocarbon source rocks. Deposition of thinly-bedded and laminated tuffs as well as positive Eu anomaly corroborate the possible occurrence of anoxic geological event closely related to contemporaneous volcanic eruption, which would play a key part in development of the Chang 91 member of high-grade hydrocarbon source rocks.
