Recently, there has been a growing evidence of its potential benefits in the treatment of various diseases. The CT has been constantly developing with the emergence of various modern and improved cupping devices. It is now evident that cupping could adjust the Qi, blood, Yin and Yang, dredge the meridian, as well as relieve the effect of illness, achieve fitness and relative equilibrium of Yin-Yang. It exerts its effects through the negative pressure suction via the mechanical and thermal stimulations, and the negative pressure effects induced by cupping. This article gives an overview of CT practice, its historical development, as well as its therapeutic effects and mechanism. Furthermore, a new and updated classification of CT was briefly introduced.展开更多

The results showed that (1) The present therapy is effective for enuresis with cure rate of 66.18% and total effective rate of 92. 65 %; (2) The curative effects was related with the syndrome differentiation (P <0. 01), e. g. it is effective for deficiency of kidney-Yang and deficiency of Qi in lung and spleen types, but ineffective for the type of downward flow of damp-heat; (3) The therapeutic effect was also closely related with the course of disease. The shorter the course of illness lasted, the more effective the therapy was, indicating that such patients should be treated in the early stage. This method is not only comparable to other conventional acupuncture methods in respects of the cure rate and total effective rate, but is also simple to apply, safe to use, easy to be accepted by children and adverse-effect free. It is deserved to be popularized as a effective therapy for enuresis in children patients.展开更多

For these purpose, we have calculated the various nuclear densities, the corresponding root mean square radii and nuclear binding energies. The density dependent initial neutron and proton exciton numbers have been also calculated which give the ability to investigate the neutron and proton induced reaction cross-sections for these target nuclei using hybrid model for pre-equilibrium nuclear reactions. The calculated results are compared with available experimental data.展开更多

Existing approaches rely on two forms of symbolic-expression representation: expanded sum-of-product form and arbitrarily nested form. Expanded form suffers the problem that the number of product terms grows exponentially with the size of a circuit. Nested form is neither canonical nor amenable to symbolic manipulation. In this paper, we present a new approach to exact and canonical symbolic analysis by exploiting the sparsity and sharing of product terms. This algorithm, called totally coded method (TCM), consists of representing the symbolic determinant of a circuit matrix by code series and performing symbolic analysis by code manipulation. We describe an efficient code-ordering heuristic and prove that it is optimum for ladder-structured circuits. For practical analog circuits, TCM not only covers all advantages of the algorithm via determinant decision diagrams (DDD) but is more simple and efficient than DDD method.展开更多

Magnetic particles (Fe3O4) were deposited on the SiO2 surface by varying the molar ratio of [Fe2+]/[Fe3+] and the molar concentration of iron salts. The obtained magnetic hollow silica spheres exhibited a super-paramagnetic behavior at room temperature. Scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray powder scattering (XRD) were applied to characterize the MHSS. Besides, their unit cell parameters are calculated according to results indexing to XRD, the MHSS sample prepared at 0.10 M iron salts and 2:1 molar ratio of [Fe2+]/[Fe3+] has a largest cell angle (β) of unit cell. Due to large hollow cavity space and super-paramagnetic characteristics, the inner amino-functionalized MHSS could be labeled with radioisotope 99Tcm to study the MHSS’s magnetic targeting distribution in vivo. These results indicate that the MHSS has potential in the magnetic targeted drug delivery system which reduces the damage to normal cells and improves the therapeutic effect of cancer.展开更多
