Methods: Sixty patients with CSA were randomly allocated into an observation group or a control group, with 30 cases in each group. The observation group was treated with warm needling moxibustion plus Kai Qing Long Suo tuina therapy, while the control group was treated with warm needling moxibustion alone. Warm needling moxibustion was conducted once every other day and tuina was con ducted once a day, 7-day treatme nts for one course. The clin ical efficacy and vertebral artery blood flow was observed after one course of treatment. Results: After treatment, the total effective rate was 93.3% in the observation group versus 80.0% in the control group, and there was a significant differenee between the two groups (P<0.05). After treatment, the systolic blood flow velocity of vertebral artery increased in both groups, with statistical significanee compared with that before treatment (both P<0.05), and the blood flow velocity in the observation group was faster than that in the control group, with statistical significanee between the two groups (P<0.05). Conclusion: Both warm needling moxibustion plus Kai Qing Long Suo tuina therapy and warm needling moxibustion alone are both effective for CSA, can improve the systolic blood flow velocity of vertebral artery. The curative effect of warm needling moxibusiton plus Kai Qing Long Suo tuina therapy is better than that of warm needling moxibustion alone.展开更多

We used Quantum Espresso and EPW codes to evaluate the electron density of states, the electronic heat capacity coefficient, the electron-phonon coupling strength, the number of mobility electrons, and the electronic heat conductivity. The electronic properties for ThN, ThC and UN using a slightly different approach that were previously evaluated are discussed and the results are compared. We confirmed that while the electronic heat capacity coefficient is linearly dependent on the electron density of states at Fermi energy, such a simple relation could not be used to determine the difference in the electronic heat conductivity of investigated materials. The highest heat conductivity was registered in ThN. These metallic fuels also have high U/Th density, therefore are more economical since enrichment is expensive. Furthermore, it is important to examine swelling in these high-density fuels. We evaluated that UN had 42% more U atoms per unit volume than UO2 and a 55% higher volume increase when accommodating one Xe atom in one interstitial of a (2 × 2 × 2) supercell. However, for He, the volume increase was 27% lower in UN. Interestingly, even though the Th atom’s density in ThN and ThC was lower than that of U atoms in the UN compound, a similar trend of volume changes was found. We concluded, therefore, that when we consider swelling, the local structural symmetry (tetrahedral versus octahedral sites) is more important than the density of atoms. The 37 % greater of absolute value of the total energy increase due to incorporation of Xe in ThC versus ThN cannot be explained by the crystal structure since a ThC-Xe supercell has a higher lattice constant than a ThN-Xe corresponding supercell. Such results can only be explained by investigating electronic structure.展开更多
