Our data are showed that apoptosis parameters including DNA fragmentation, nuclear morphological change and sub-G1 fraction, appeared after 24 h by 5 μM rottlerin treatment. Furthermore, rottlerin caused a decrease in 72% of ODC protein expression and an increase in threonine, rather than serine and tyrosine dephosphorylation on ODC enzyme compared with the control after incubation for 10 h. To determine whether ODC could down-regulate rottlerin-induced apoptosis, HL60 cells were stably transfected with ODC cDNA. HL60-ODC cells exhibited a 2.5-fold increase in ODC protein compared with vector only (HL60-pcDNA3) or HL60 cells.

在我们筛选天然化合物实验中，发现rottlerin抑制鸟胺酸去羧化活性最具成效，之前的研究人员已知蛋白激Cd调节鸟胺酸去羧化的活性，因此在人类白血病HL60细胞处理rottlerin的实验中发现加入rottlerin二十四小时后，细胞进行计划性死亡，并可侦测到DNA片段、细胞核浓缩及sub-G1提增；而细胞处理药物十小时后与控制组细胞比较，观察到鸟胺酸去羧化的蛋白表现与活性下降50﹪以上；除此以外，测定鸟胺酸去羧化去磷酸化的情况，发现於酥胺酸位置有显著差异，而丝胺酸和酪胺酸位置并无差异。

In order to clear heterogeneous reservoirs waterflooding performance, and decreased interlayer and within-layer contradictions, and improved the water flooding recovery, experimental study should be conducted first, This paper based on Pucheng Sasan reservoir sandstone cores to study object. Multi-point pressure measurement of water flooding oil experimental apparatus was established. Through the three-layer water flooding experiment to study injection strategy, interlayer interference and recovery factors. True sandstone micro-model water flooding used newly developed color visual image analysis system researched water-drive types, forms of residual oil and waterflood efficiency. Percolation mathematical model was established, black oil simulation program was developed, long-core displacement experimental results were matched, pressure and saturation change were researched by the simulation matching results.

Based on the technique of PIV,We calculated the light intensity of the bubble interface and discovered that the intensities of lighr reflected or refracted twice succeedingly abide by the rules of geometric series , and the light will disappear after reflecting or refracting 4 times by the bubbles.

基于粒子成像测速的流体可视化技术，根据菲涅耳公式计算了入射到水中气泡界面的光强，得出点光源连续两次反射或折射的光强具有等比数列的规律，光线在气泡界面反射、折射4次就变成完全偏振光且光线几乎消失。

Owing to the variability of HVR1, the method to check anti-HVR1 antibodies need to cloning and expressing the gene of HVR1 of every sera and that poses some problem. For example, it needs lots of time and money, and the sample must come from viremic patients. It is urgent to acquire a broadly cross-reactivity HVR1 antigen to check the antiHVR1 Ab in the sera of HCV infected patients by ELISA.

由于HVR1的高变性，因此要想测定血清中抗HVR1水平，通常要克隆表达待测血清中的HVR1基因，但该方法时间长、费用高，并仅对HCV、RNA阳性血清适用，所以急需一种具有极高交叉反应性的HVR1抗原，才可通过ELISA对病人的HVR1抗体进行检测。
