OVCs were isolated by density ladder centrifugation in the 4th week, and then OVC's morphology was observed under transmission electromicroscrope and immunocytochemistry were performed to detect the expression of ICAM-1. Results Observing OVC's morphology under transmission electromicroscrope showed that OVC was infantile and undifferentiated with big nucleus, clear nucleolus, large nucleoplasm-ratio, small mitochondria, and little endoplast. In initial stage of damaged liver, OVCs and the expression of ICAM-1 mostly distributed around Hering duct, and then gradually increased and expanded toward hepatic lobule, shown by staining paraffin sections with HE, immunochemistry and transmission electromicroscrope. Immunocytochemistry indicated that ICAM-1 expression on OVCs was positive.

Nietzsche"s political philosophy is not piled up a dish of messy sand by maxim form, the writer thinks that Nietzsche"s political construction has his continuous logicality. It"s an expression of political philosophy that is constructed on the base of force will and life will, it makes life reach at a transitional bridge that can supply condition for the salvation of art. Thus, there are three understandings here. Firstly, politics is an objective expression of power will, also is an external expression of power will. The real politics depends on power will and services to their requirement and regulation; Secondly, the life faces on the double crises, on the one hand, the life falls into denial of Christian morality. Morality of Christianity presumes another world that life never touch for. This is world of soul belief and pursue, meanwhile, life is depreciated and degenerated as "evil", so the value of life suffers from misunderstanding and denial. Things of presence are subverted as things of exeunt."Uprising of slave in morality" results in the denial of ",master morality, at the same time, although modern democratic politics that based on morality of Christianity makes person return secular life and makes life identity and trite. This kind of politics creates privation of special vulture and race. On the other hand, internal requirement of power will results in the crisis of life because the characteristics of power will is continuous making and destroy.

尼采的政治哲学并非是以格言形式堆积而成的一盘散沙，笔者认为，尼采的政治建构有其一贯的逻辑性，体现为其政治哲学是建构在强力意志或生命意志基础上的并使生命达至艺术拯救提供条件的一座过度性桥梁，对此有三层理解：首先政治是权力意志的一种客观体现，是全力意志的一种外化，真正的政治必须立足于权力意志之上并服务于其要求和规定；其次，生命面临着双重危机，一方面，生命陷入基督教道德的否定之中，基督教道德设定了一个生命遥不可及的彼岸世界，这是灵魂信仰和追求的世界，同时生命被贬堕为"恶"，这样，生命的价值遭到误解和否定，在场的事物被颠覆为退场的事物，"主人道德"被否定，这是"道德上的奴隶起义"的结果，同时基于基督教道德之上的现代民主政治虽然使人回到了尘世，但是又将生命齐一化和平庸化，造成特殊文化和特殊种族的缺位，而正是这种文化和这种种族才能真正地肯定生命；另一方面，生命的危机是权力意志内在的要求所致，因为权力意志的一个特质就是连续地生成和毁灭，就生命本身就是权力意志而言，毁灭就是其必然的命运。

The degradating and redistributing of ECM were migration of VSMC and vascular remodeling through inhibiting the production of PDGF-BB and the activation of MMPs so to prevent the vascular stenosis.⑤Orthotopic hybridism in situ: The expression of MMP-3 increased after operation, the tendency and intensity were parallel to the expression of NF-κB. Tongxinluo could decrease the expression of MMP-3 and NF-κB. The study showed that the producting and activating of MMP-3 were modulated by NF-κB. The inhibition to the producting and activating of MMp-3 of Tongxinluo was mediated by inhibiting the activating of NF-κB. Conclusion ①The rabbit vascular stenosis model could be established successfully by plain balloon damage, the operation process was easy, economical and practical.
