Based on the analysis and experiment, the training group descending Enhanced Combination Algorithm (ECA) is proposed.The analysis of the generalized property and sample error shows that the ECA can heighten the study speed and reduce individual error.展开更多

Methods: A total of 118 patients with ACI who were admitted in our hospital from October 2016 to September 2017 were included in the study and randomized into the observation group and the control group, with 59 cases in each group. The patients in the control group were given blood pressure control, blood sugar control, micro-circulation improvement, anti-platelet aggregation, nerve nourishing, and lipid regulation. On the above basis, the patients in the observation group were given intravenous injection of NBP sodium chloride injection. The patients in the two groups were treated for 14 d. The morning fasting venous blood before treatment, 7 d and 14 d after treatment in the two groups was collected, and centrifuged for the serum. And IL-6, TFN-α, hs-CRP, SOD, MDA, NSE, VEGF, BDNF, and bFGF were measured. Results: 7 d and 14 d after treatment, the serum IL-6, TFN-α and hs-CRP in the observation group were significantly lower than those in the control group. Besides, 7 d and 14 d after treatment, the serum SOD in the observation group was significantly higher than that in the control group, while MDA was significantly lower than that in the control group. The serum NSE 7 d and 14 d after treatment in the observation group was significantly lower than that in the control group, while VEGF, BDNF, and bFGF were significantly higher than those in the control group. Conclusions: NBP in the treatment of ACI can down regulate the expression of inflammatory cytokines to play an anti-inflammatory effect, increase the antioxidant ability to remove OFR, improve the neurocyte metabolism, and effectively play the nerve protecting and prognosis improvement role.展开更多

Our calculation results show that NbAs and TaAs have similar phase diagrams, the same structural phase transition sequence I4_1 md→P6 m2→P2_1/c→Pm3 m, and slightly different transition pressures. The phase transition sequence of NbP and TaP differs somewhat from that of NbAs and TaAs, in which new structures emerge, such as the Cmcm structure in NbP and the Pmmn structure in TaP. Interestingly, we found that in the electronic structure of the high-pressure phase P6 m2-NbAs, there are coexistingWeyl points and triple degenerate points, similar to those found in high-pressure P6 m2-TaAs.展开更多
