婴儿川崎病伴阿司匹林过敏一例并文献复习

川崎病(KD)为小于5岁以下小儿好发的全身系统性血管炎,最严重的并发症是冠状动脉瘤。静脉注射免疫球蛋白(2g/Kg)+大剂量阿司匹林(乙酰水杨酸)是标准KD治疗方案,低剂量阿司匹林(3~5mg/kg/d)发挥抗血小板效应。阿司匹林是KD治疗的一线用药,小于12岁以下患儿过敏几率26.5%。报告一例KD婴儿在阿司匹林治疗中出现过敏反应并复习文献。     

Perturbation to Mei symmetry and Mei adiabatic invariants for mechanical systems in phase space

For a perturbed mechanical system in phase space, considering d/dt in the structure equation and process of proof including infinitesimal parameter ε obviously, this paper studies the perturbation to Mei symmetry and adiabatic invariants. Firstly, the exact invariant induced directly from the Mei symmetry of the system without perturbation is given. Secondly, based on the concept of high-order adiabatic invariant, the determining equations of the perturbation to Mei symmetry are established, the condition of existence of the Mei adiabatic invariant led by the perturbation to Mei symmetry is obtained, and its form is presented. Lastly, an example is given to illustrate the application of the results.     

浅析1929年非洲殖民地发展法案

20世纪初,有"殖民帝国主义"之称的英国,其经济在世界上"一枝独秀"局面的结束、国际局势的变化特别是其他国家对其殖民地的觊觎,促使其调整帝国殖民地统治政策,1929年7月出台的非洲殖民地发展法案即是其结果,企图通过发展非洲殖民地来治愈经济萧条,达到英国经济利益和非洲殖民地社会发展"双赢"的目的。然而,该法案未能扭转英国经济的不利局面;并且使殖民地社会经济恶化,引起当地民众的反抗。     

New conserved quantities of Noether--Mei symmetry of mechanical system in phase space

This paper studies two new types of conserved quantities deduced by Noether Mei symmetry of mechanical system in phase space. The definition and criterion of Noether Mei symmetry for the system are given. A coordination function is introduced, and the conditions under which the Noether- Mei symmetry leads to the two types of conserved quantities and the forms of the two types of conserved quantities are obtained. An illustrative example is given. The coordination function can be selected according to the demand for finding the gauge function, and the choice of the coordination function has multiformity, so more conserved quantities deduced from Noether Mei symmetry of mechanical system can be obtained.     

A new type of conserved quantity of Mei symmetry for relativistic nonholonomic mechanical system in phase space

In this paper, a new type of conserved quantity induced directly from the Mei symmetry for a relativistic nonholonomic mechanical system in phase space is studied. The definition and the criterion of the Mei symmetry for the system are given. The conditions for the existence and form of the new conserved quantity are obtained. Finally, an example is given to illustrate the application of the result.
