In Leaves of grass, he eulogized ＂self＇ with great enthusiasm and expressed the idea that self was eternal and imperishable, just like the cycle of the nature. The concept of the ＂self＇ embodied in Whitman＇s Leaves of grass possessed double structure： body and soul; microcosmic and macroscopic. Whitman＇s recognition to ＂self＇ was the continuation of Emerson＇s thought, but he also had his own breakthrough. He explored the connotation of ＂self＇ from the relation self with mankind, time, nature and God. Self was always undying not only in body but also in soul. The relations among people were the foundation of self, which possessed boundless time and measureless space and which could come true through rotation of nature in perpetuity and be flow of empathy in perpetuity.展开更多

However, through an exploration of his early articles and poems, it could be found that both his political philosophy and cultural ideas were in accordance with the white identity of Americans, giving priority to the interests of white people rather than every single American resident. In this sense, it seems appropriate to consider Whitman as the spokesman for American whites.展开更多

目的:利用分子模拟技术筛选以凝血因子Ⅺa(FⅪa)为靶点的宽体金线蛭抗凝多肽,并通过实验验证其抗凝活性。方法:采用“模拟+实验”的活性肽筛选策略,以FⅪa为抗凝活性靶点,首先采用HPEPDOCK和Discovery Studio ZDOCK 2种分子对接技术进...目的:利用分子模拟技术筛选以凝血因子Ⅺa(FⅪa)为靶点的宽体金线蛭抗凝多肽,并通过实验验证其抗凝活性。方法:采用“模拟+实验”的活性肽筛选策略,以FⅪa为抗凝活性靶点,首先采用HPEPDOCK和Discovery Studio ZDOCK 2种分子对接技术进行初步筛选,随后运用分子动力学模拟方法对结合能较高的FⅪa-多肽复合物进行动力学模拟复筛。通过MM/PBSA模块计算复合物的结合自由能,筛选出稳定结合的宽体金线蛭多肽。最后,采用固相合成法化学合成目标多肽,并进行体外抗凝活性测定以验证其生物活性。结果:筛选出1条与FⅪa结合效果最佳的抗凝肽,其氨基酸序列为VILTNPSGTLTEAIVK。体外活性实验结果表明,该宽体金线蛭来源的抗凝肽能够显著延长凝血时间。通过发色底物法进一步验证,证实该多肽能够与FⅪa结合并显著抑制其对发色底物s-2366的酶切活性。结论:筛选出1条以FⅪa为靶点的宽体金线蛭抗凝多肽,其能够通过特异性酶切FⅪa显著延长凝血时间,展现出良好的抗凝活性。该研究验证了“模拟+实验”筛选策略的有效性,为开发新型抗凝药物提供了潜在的候选多肽。展开更多

The celebration of life and for centuries, they all take life and death seriously, but they also have different views towards death and life. This article will center on major American poets such as Henry Wadsworth Longfellow Emily Dickinson, Robert Frost, Walt Whitman and so on. This article will try to have a discussion on the basis of ethical review and interpretation about the view of life and death, to reveal the similarities and differences about the view of life and death in different poets’ poems, to find a method for us to learn about how to adapt to the modern civilization on the basis of ethical review and interpretation, how to understand human life and death how to face life and death, how to survive beyond life and death how to live a wonderful life through understanding human life and death in a proper way.展开更多
