Of the few avian influenza viruses that have crossed the species barrier to infect humans, the highly pathogenic influenza A （H5NI） strain has claimed the lives of more than half of the infected patients. With largely unknown mechanism of lung injury by H5N1 infection, acute respiratory distress syndrome （ARDS） is the major cause of death among the victims. Here we present the fact that HSN 1 caused autophagic cell death through suppression of mTOR signaling. Inhibition of autophagy, either by depletion of autophagy gene Beclinl or by autophagy inhibitor 3-methyladenine （3-MA）, significantly reduced H5N1 mediated cell death. We suggest that autophagic cell death may contribute to the development of ARDS in H5N1 influenza patients and inhibition of autophagy could therefore become a novel strategy for the treatment of H5N1 infection.

光学薄膜的光学特性与其每一膜层的厚度密切相关,为了制备出符合要求的光学薄膜产品,在制备过程中必须监控膜厚。光学薄膜实时监控精度决定了所镀制的光学薄膜的厚度精度。针对光电极值法极值点附近监控精度低、无法精确监控非规整膜系的缺陷,提出了新的光学薄膜膜厚监控算法。该算法通过数学运算,使得光学薄膜的光学厚度与透射率呈线性关系,并且有效地消除光源波动、传输噪声等共模干扰的影响,算法精度可控制在2%以内。

A method to extract crude heparin sodium from pig intestinal mucosa by dialysis and spray drying was established. The pig intestinal mucosa was treated in the following steps: enzymolysis, resin exchange adsorption-washing, elution, pressure filtration, dialysis, spray drying. Activity of the product was measured using a heparin anti-IIa factor assay kit. The yield of crude heparin obtained by this method was 2.79% higher than that of oven drying method;the production of 1 kg crude heparin sodium saved 43.4 pigs small intestine. The activity was 98.48 ± 2.49 IU/mg (n = 5), 15.18 IU/mg higher than that obtained by oven drying method. The product is pale white powder, attractive color and easy to dissolve.

脉冲电弧离子镀膜技术是近几十年来新发展的一种镀膜方法,有着广阔的应用前景.然而,在镀膜过程中,出现的拉弧和停弧现象严重影响了脉冲放电的稳定性,进而影响了膜层质量和镀膜效率.为此,采用两级电容充电的引弧方式来减拉弧现象;同时,使用双脉冲触发方法来提高放电的可靠性,减少停弧现象的产生.使用改进后的离子源实验表明,镀膜过程中拉弧和停弧现象明显减少,脉冲放电更为稳定.由此说明,对离子源放电稳定性的改造是有效的,能够很好的满足薄膜镀制的需要.
