实验性脾虚证大鼠血清中微量元素含量的研究

用破气苦降药加饮食失节法复制了大鼠脾虚证模型。采用原子吸收光谱法检测了血清发Ｚｎ、Ｃｕ和Ｆｅ的含量。本研究证明，脾虚证大鼠血清Ｚｎ值明显降低（Ｐ＜０．００１）；Ｃｕ值、Ｆｅ值无明显差异（Ｐ＞００５）；Ｃｕ／Ｚｎ比值上升。用中药加味四君子汤治疗后，血清Ｚｎ值明显回升并高于正常水平（Ｐ＜００５），Ｃｕ值回升（Ｐ＜０．０５），但Ｆｅ值和Ｃｕ／Ｚｎ比值与自然恢复及对照组比较无显著性差异。这说明：１．脾虚组Ｚｎ的降低可能与消化吸收障碍有关；２．加味四君子汤对脾虚证时血清Ｚｎ及Ｃｕ／Ｚｎ比值的变化有明显的调整和恢复作用．

On the Foundations of Constructive Mathematics – Especially in Relation to the Theory of Continuous Functions

We discuss the foundations of constructive mathematics, including recursive mathematics and intuitionism, in relation to classical mathematics. There are connections with the foundations of physics, due to the way in which the different branches of mathematics reflect reality. Many different axioms and their interrelationship are discussed. We show that there is a fundamental problem in BISH (Bishop’s school of constructive mathematics) with regard to its current definition of ‘continuous function’. This problem is closely related to the definition in BISH of ‘locally compact’. Possible approaches to this problem are discussed. Topology seems to be a key to understanding many issues. We offer several new simplifying axioms, which can form bridges between the various branches of constructive mathematics and classical mathematics (‘reuniting the antipodes’). We give a simplification of basic intuitionistic theory, especially with regard to so-called ‘bar induction’. We then plead for a limited number of axiomatic systems, which differentiate between the various branches of mathematics. Finally, in the appendix we offer BISH an elegant topological definition of ‘locally compact’, which unlike the current definition is equivalent to the usual classical and/or intuitionistic definition in classical and intuitionistic mathematics, respectively.

Structure of the human CLC-7/Ostm1 complex reveals a novel state

CLC-7 functions as a Cl?/H+ exchanger in lysosomes. Defects in CLC-7 and its β-subunit, Ostm1, result in osteopetrosis and neurodegeneration. Here, we present the cryogenic electron microscopy (cryo-EM) structure of the human CLC-7/Ostm1 complex (HsCLC-7/Ostm1) at a resolution of 3.6 ?. Our structure reveals a new state of the CLC-7/Ostm1 heterotetramer, in which the cytoplasmic domain of CLC-7 is absent, likely due to high flexibility. The disordered cytoplasmic domain is probably not able to restrain CLC-7 subunits and thus allow their relative movements. The movements result in an approximately half smaller interface between the CLC-7 transmembrane domains than that in a previously reported CLC-7/Ostm1 structure with a well-folded cytoplasmic domain. Key interactions involving multiple osteopetrosis-related residues are affected by the interface change.
