    目的 慢性肾脏病患者随着肾脏功能的逐渐减退,早期即可出现钙磷失衡、维生素D缺乏、甲状旁腺激素以及成纤维生长因子FGF23的升高,而这种矿物质代谢紊乱又可促使患者出现继发性甲状旁腺功能亢进以及加重肾脏损伤。目前CaSR激动剂作为有效抑制甲状旁腺增生的临床药物,适用于已发生SHPT的透析患者,为探究其是否也能防治继发性甲状旁腺亢进、矿物质代谢紊乱及肾脏损伤,本研究通过5/6肾大部切除术结合高磷饮食建立尿毒症大鼠模型,分别在造模成功早期预防性给予大鼠西那卡塞干预以及在大鼠慢性肾衰确立后给予盐酸西那卡塞干预,从两个时期观察分析盐酸西那卡塞是否可以缓解尿毒症大鼠继发性甲状旁腺亢进及肾脏的损伤。 方法...Backgroud With the development of chronic kidney disease (CKD), the CKD patients can show the imbalance of calcium and phosphate,deficiency of vitamin D,the rise of parsthyroid homone and fibroblst growth factor 23 in the early stage of kidney injury.

    The Creation of an Indigenous Genealogy: for the Discipline of “Political Science” in Modern China

    Get PDF
    This paper argues that the formation of political science as an academic discipline in modern China was the result of a complex process of cultural interaction. The arrival of Western political knowledge and related academic theories in late-nineteenth and early twentieth-century China led to heated debates among Chinese scholars. Did political science exist as an indigenous tradition of knowledge? Some authors asserted not only that a discipline similar to Western political science had existed in China but that it even possessed its specific conceptual framework and a unique set of classical works and authors. Among of the legacy of this reshaping of political science’s disciplinary history are courses entitled “History of Chinese Political Science” or “History of Chinese Political Thought” which are taught at Political Science Departments in many Chinese universities. The intellectuals involved in the einvention of Chinese political science had different academic backgrounds and advocated conflicting political positions. Still, they all helped to bring Chinese native knowledge into dialogue with the Western discipline of political science. Starting point of this paper is the question of the narrative requirements of the discipline since the middle of the nineteenth century. I will then analyze different attempts to reshape the Chinese tradition in view of Western concepts and the ways in which indigenous contents was analyzed by applying a Western disciplinary methodology. Finally, I will discuss the “disciplinary classics” on which such interpretations were based

Based on Wavelet Transform, instantaneous parameter extraction and higher-order cumulants are used to recognize the Underwater Sound Signal, including Single carrier(MFSK,MPSK, QAM) and multicarrier(OFDM). Simulation results show that the rate of modulation identification is able to keep 82% above in the situation of low SNR, meaning that the proposed method has a good ability of identification.国家自然科学基金(61471309,61671394); 中央高校基本科研业务费专项资金(20720170044

    The Ritual of Chou: as an EXPRESSION under the Knowledge Crisis of Later Imperial China

    Get PDF
    From the second half of 19th century China, changes in fields of knowledge had been more closely connected with the practical political transformations. During these continuous transformations, many progressives in or outside the government had disputed on how to reinterpret and make use of the traditional classics. This paper tries to investigate such disputations on a classic of the Old Text School: The Ritual of Chow. This classic had finally been transferred into a special expression of western political science under the influence of the Imperial Examination reformation from 1902-1905
