This study aims to investigate the addition of Zn on the corrosion property and cytocompatibility of Mg- 2Gd-xZn (x = 0, 3, 4 and 5;wt%) alloys, which were prepared by gravity permanent mold casting and solution treatment, respectively. The results show that the intermetallic phases of these ternary alloys are mainly composed of Mg12GdZn and Mg3GdZn3. The content of secondary phases as well as the grain size is greatly dependent on the Zn addition. Compared to the binary Mg- 2Gd alloy, the corrosion resistance of the most ternary alloys is significantly improved. Furthermore, the in vitro cell culture study demonstrates the potential cytocompatibility of the developed ternary alloys. It indicates that a series of Mg-2Gd-xZn (x = 0, 3, 4 and 5;wt%) with medically acceptable corrosion rate are developed and show great potential use as a new type of biodegradable implants.

Objective To perform gene expression profiles comparison so that to identify and understand the potential differences in pathogenesis between the pandemic and seasonal A （H1N1） influenza viruses. Methods A549 cells were infected with A/California/07/09 （H1N1） and A/GuangdongBaoan/51/08 （H1N1） respectively at the same MOI of 2 and collected at 2, 4, 8, and 24 h post infection （p.i.）. Gene expression profiles of A549 cells were obtained using the 22 K Human Genome Oligo Array, and differentially expressed genes were analyzed at selected time points. Results Microarrays results indicated that both of the viruses suppressed host immune response related pathways including cytokine production while pandemic H1N1 virus displayed weaker suppression of host immune response than seasonal H1N1 virus. Observation on similar anti-apoptotic events such as activation of apoptosis inhibitor and down-regulation of key genes of apoptosis pathways in both infections showed that activities of promoting apoptosis were different in later stage of infection. Conclusion The immuno-suppression and anti-apoptosis events of pandemic H1N1 virus were similar to those seen by seasonal H1N1 virus. The pandemic H1N1 virus had an ability to inhibit biological pathways associated with cytokine responses, NK activation and macrophage recognition .

通过钻井、测井、岩芯及实验数据综合分析,对松辽盆地北部青山口组致密油特征与聚集模式进行了深入研究。结果表明,松辽盆地北部青山口组致密油分布在三角洲前缘及湖相区,储集层属于片状浊流形成的致密储层,孔隙度一般小于10%,局部可达到15%,渗透率普遍小于0.1×10^(-3)μm^2。储集空间为粒间孔、粒内溶孔、铸模孔、微裂缝等,孔隙直径分布在5~200μm,孔喉半径小于0.5μm。烃源岩是青山口组一段和二段湖相泥岩,具有广覆式分布特点,干酪根为Ⅰ型或Ⅱ1型,平均有机碳含量(TOC)为1%~3%,热成熟度(Ro)为0.9%~1.1%,属优质成熟烃源岩。聚集模式为储层平面上大面积连续分布,无明显边界,纵向上储层与源岩交互叠置形成千层饼状,具有紧密接触的源储共生型成藏组合。因此,致密油聚集宏观上受成熟烃源岩控制,其次取决于致密储层分布。致密油储层普遍超压,含油级别为油斑和油迹,不存在油浸和富含油,原油属于低黏度轻质原油,单井无自然产能,采取水平钻井并进行大规模分段体积压裂才能获得工业产能。对其沉积及聚集模式的认识为松辽盆地北部致密油勘探拓展了新的空间,具有实际指导意义。

根据现有考古证据和葡萄酒发展历史分析,认为葡萄酒的最初起源地在远东,包括中国、叙利亚、土耳其、格鲁吉亚、亚美尼亚、伊朗等国家。葡萄酒由最初的起源地远东传入欧洲,再由欧洲传入东方和世界其他地区。因此,包括中国等国家的远东地区是葡萄、葡萄酒的起源地,欧洲则是后起源中心,即栽培葡萄的后驯化与传播中心。根据这些分析结果,结合目前世界葡萄酒的格局,提出应将世界葡萄酒生产国分为古文明世界、旧世界和新世界,并认为中国是葡萄酒古文明世界的代表。
