| 1 | Numerical Analyses of Idealized Total Cavopulmonary Connection Physiologies with Single and Bilateral Superior Vena Cava Assisted by an Axial Blood Pump显示文摘Our study evaluated the hemodynamic performance of an axial flow blood pump surgically implanted in idealized total cavopulmonary connection(TCPC)models.This blood pump was designed to augment pressure from the inferior vena cava(IVC)to the pulmonary circulation.Two Fontan procedures with single and bilateral superior vena cava(SVC)were compared to fit the mechanical supported TCPC physiologies.Computational fluid dynamics(CFD)analyses of two Pump-TCPC models were performed in the analyses.Pressure-flow characteristics,energy efficiency,fluid streamlines,hemolysis and thrombosis analyses were implemented.Numerical simulations indicate that the pump produces pressure generations of 1 mm to 24 mm Hg for rotational speeds ranging from 2000 RPM to 5000 RPM and flow rates of 2 LPM to 4 LPM.Two surgical models incorporated with the pump were found to be insignificant in pressure augmentation and energy boost.The risk assessment of blood trauma and thrombosis generation was evaluated representatively through blood damage index(BDI),particle resident time(PRT)and relative resistant time(RRT).The hemolysis and thrombosis analyses declare the advantage of the pump supported bilateral SVC surgical scheme in balancing flow distribution and reducing the risk of endothelial cell destruction and trauma generation. | Xudong Liu Yunhan Cai Bing Jia Shengzhang Wang Guanghong Ding | 2018 | Computer Modeling in Engineering & Sciences2018，，8： | 1 |
| 2 | Studies on plasma-activated perilla seed oil:Diagnosis,optimisation,and validation of reactive species显示文摘Recently,the applications of cold atmospheric plasma(CAP)in liquid treatment have attracted increasing attention owing to its excellent medical efficacy.It has been proved that CAP can effectively enhance the biological activity of vegetable oils due to the generation of reactive species.Optimising the reactor parameter is an important approach to regulate reactive species in plasma-activated oil to obtain better biological effects.In this study,a self-made jet array driven by a pulsed power supply was used to generate large-area plasma to irradiate perilla seed oil(PSO),with the formation of plasmaactivated perilla seed oil(PAPSO).By means of laser-induced fluorescence and chemical titration,the relative density of hydroxyl radical radical in plasma jet,as well as the activity of PAPSO were measured under different discharge parameters,and realised the control of the activity of PAPSO.In vitro experiments showed that PAPSO significantly enhanced its ability to inhibit cancer cells proliferation and induce apoptosis after plasma treatment,which provides a reference for cancer treatment.This study is helpful to further understand the influence of plasma dose effect on the activity of media and provide guidance for related plasma medical applications. | Xiaolong Wang Jun Liu Quanxin Li Lian Li Shanrui Li Yunhan Ding Tong Zhao Ying Sun Yuantao Zhang | 2023 | High Voltage2023，8，4： | 0 |
