| 1 | Aerodynamic simulation of evacuated tube maglev trains with different streamlined designs显示文摘Based on the Navier-Stokes (N-S) equations of incompressible viscous fluids and the standard k-ε turbulence model with assumptions of steady state and two dimensional conditions, a simulation of the aerodynamic drag on a maglev train in an evacuated tube was made with ANSYS/FLOTRAN software under different vacuum pressures, blockage ratios, and shapes of train head and tail. The pressure flow fields of the evacuated tube maglev train under different vacuum pressures were analyzed, and then compared under the same blockage ratio condition. The results show that the environmental pressure of 1 000 Pa in the tube is the best to achieve the effect of aerodynamic drag reduction, and there are no obvious differences in the aerodynamic drag reduction among different streamline head shapes. Overall, the bluntshape tail and the blockage ratio of 0.25 are more efficient for drag reduction of the train at the tube pressure of 1 000 Pa. | Xuyong CHEN Lifeng ZHAO Jiaqing MA Yuansen LIU | 2012 | Journal of Modern Transportation2012，20，2： | 11 |
| 2 | 3D bioprinting of integral ADSCs-NO hydrogel scaffolds to promote severe burn wound healing显示文摘Severe burns are challenging to heal and result in significant death throughout the world.Adiposederived mesenchymal stem cells(ADSCs)have emerged as a promising treatment for fullthickness burn healing but are impeded by their low viability and efficiency after grafting in vivo.Nitric oxide(NO)is beneficial in promoting stem cell bioactivity,but whether it can function effectively in vivo is still largely unknown.In this study,we bioprinted an efficient biological scaffold loaded with ADSCs and NO(3D-ADSCs/NO)to evaluate its biological efficacy in promoting severe burn wound healing.The integral 3D-ADSCs/NO hydrogel scaffolds were constructed via 3D bioprinting.Our results shown that 3D-ADSCs/NO can enhance the migration and angiogenesis of Human Umbilical Vein Endothelial Cells(HUVECs).Burn wound healing experiments in mice revealed that 3D-ADSCs/NO accelerated the wound healing by promoting faster epithelialization and collagen deposition.Notably,immunohistochemistry of CD31 suggested an increase in neovascularization,supported by the upregulation of vascular endothelial growth factor(VEGF)mRNA in ADSCs in the 3D biosystem.These findings indicated that 3D-ADSC/NO hydrogel scaffold can promote severe burn wound healing through increased neovascularization via the VEGF signalling pathway.This scaffold may be considered a promising strategy for healing severe burns. | Yu Wu Tangzhao Liang Ying Hu Shihai Jiang Yuansen Luo Chang Liu Guo Wang Jing Zhang Tao Xu Lei Zhu | 2021 | Regenerative Biomaterials2021，8，3： | 2 |
