对渤海东部DLC70-1孔157个沉积物样品进行了稀土元素（REE）测定，结合有孔虫丰度和粒度参数研究，探讨了该孔稀土元素地球化学特征与晚第四纪环境变化关系。DLC70-1孔沉积物物源分析表明，该孔沉积物物质来源比较稳定，其沉积物主要来源于黄河。渤海东部DLC70—1孔REE的分布特征与晚第四纪沉积环境变化密切相关，约100kaBP以前，研究区发育浅海环境，∑REE含量较高，且HREE相对富集。100～75kaBP期间，2REE含量受沉积物粒度的影响，明显低于前一阶段，LREE相对富集，稀土元素分布表现为河口半咸水环境特征。75～60kaBP期间，研究区发育以细颗粒沉积物为主，∑REE含量达到高值。60-35kaBP期间为晚更新世玉木冰期中间冰阶（暖期）沉积，研究区发育滨海沉积环境，其∑REE含量总体较低，并显示LREE相对富集；随着水体深度和盐度条件发生多次波动，稀土元素分布特征也表现出小幅度变化。35～30kaBP期间，研究区发育滨岸和滨海沉积环境，其∑REE含量总体较高。30～10kaBP期间，研究区表现为河流环境，受矿物组成和沉积物粒度的影响，∑REE含量总体较低，显示向上HREE相对富集。10kaBP以来为全新世海侵期，研究区持续发育滨海一浅海沉积环境，其∑REE含量总体较高，显示LREE富集。

Pd-MoO3/SiO2 catalyst has been prepared using the method of incipient wetness impregnation. The photo absorbing behaviors and chemisorbing properties of the catalyst have been characterized by UV-vis spectra and TPD-MS experiments. The results indicated that metal Pd loaded on MoOa/SiO2 has a significant effect on the photo absorbing performance of MoOa/SiO2, and an obvious blue shift of the absorption edge is produced. Under UV irradiation, the chemisorption state of CO2 undergoes decomposing process to form CO at 481 K, and a two-site adsorption state of ethane can be formed at around 496 K. Photo-oxidation of ethane using carbon dioxide can mainly produce propanal, ethanol and acetaldehyde in the temperature range of 353-423 K. The presence of metal Pd improves the catalytic activity remarkably.

目的:探讨大鼠原代肝星状细胞(HSC)体外培养过程中,不同时期外源性转化生长因子β1(TGF-β1)对其活化的影响及相关因素的变化.方法:分离大鼠原代HSC,于无包被的塑料培养板上分别培养2,3,4,5,6,7d时予TGF-β15mg/L处理24h,倒置显微镜下观察细胞的形态变化,应用Western blot法检测处理前后细胞a-肌动蛋白(a-SMA)的变化,及活化过程中TGF-β1Ⅱ型受体(TβR-Ⅱ)的表达.结果:HSC在体外培养过程中,不同培养时间对TGF-β1的刺激活化作用反应不同.TGF-β1处理后,对培养2,3,4,5dHSC的活化有促进作用,以对培养第3天的细胞作用最明显,其a-SMA表达增加78.05%,而培养6,7d的HSC的形态和a-SMA变化不明显.培养第7天的HSC比培养第3天的细胞TβR-Ⅱ表达增高(3.30±0.83 vs 1.55±0.38,P<0.05).结论:TGF-β1对处部分活化状态中某阶段细胞的活化具有促进作用.完全活化的细胞对TGF-β1的刺激活化作用不敏感,原因与TβR-Ⅱ的表达量无关.
