| 4 | It is safe to use transdermal glyceryl trinitrate to lower blood pressure in patients with acute ischaemic stroke with carotid stenosis显示文摘Background There is concern that blood pressure(BP)lowering in acute stroke may compromise cerebral perfusion and worsen outcome in the presence of carotid stenosis.We assessed the effect of glyceryl trinitrate(GTN)in patients with carotid stenosis using data from the Efficacy of Nitric Oxide in Stroke(ENOS)Trial.Methods ENOS randomised 4011 patients with acute stroke and raised systolic BP(140-220 mm Hg)to transdermal GTN or no GTN within 48 hours of onset.Those on prestroke antihypertensives were also randomised to stop or continue their medication for 7 days.The primary outcome was the modified Rankin Scale(mRS)at day 90.Ipsilateral carotid stenosis was split:<30%;30-<50%;50-<70%;≥70%.Data are ORs with 95%CIs adjusted for baseline prognostic factors.results 2023(60.5%)ischaemic stroke participants had carotid imaging.As compared with<30%,≥70%ipsilateral stenosis was associated with an unfavourable shift in mRS(worse outcome)at 90 days(OR 1.88,95%CI 1.44 to 2.44,p<0.001).Those with≥70%stenosis who received GTN versus no GTN had a favourable shift in mRS(OR 0.56,95%CI 0.34 to 0.93,p=0.024).In those with 50-<70%stenosis,continuing versus stopping prestroke antihypertensives was associated with worse disability,mood,quality of life and cognition at 90 days.Clinical outcomes did not differ across bilateral stenosis groups.Conclusions Following ischaemic stroke,severe ipsilateral carotid stenosis is associated with worse functional outcome at 90 days.GTN appears safe in ipsilateral or bilateral carotid stenosis,and might improve outcome in severe ipsilateral carotid stenosis. | Jason P Appleton Lisa J Woodhouse Andrew Belcher Daniel Bereczki Eivind Berge Valeria Caso Hui Meng Chang Hanne K Christensen Ronan Collins John Gommans Ann C Laska George Ntaios Serefnur Ozturk Gillian M Sare Szabolcs Szatmari Yongjun Wang Joanna M Wardlaw Nikola Sprigg Philip M Bath for the ENOS investigators | 2019 | Stroke & Vascular Neurology2019，4，1： | 6 |
| 5 | Overall optimization of Rankine cycle system for waste heat recovery of heavy-duty vehicle diesel engines considering the cooling power consumption显示文摘The Rankine cycle system for waste heat recovery of heavy-duty vehicle diesel engines has been regarded as a promising technique to reduce fuel consumption. Its heat dissipation in the condensation process, however, should be taken away in time, which is an energy-consuming process. A fan-assisted auxiliary water-cooling system is employed in this paper. Results at 1300 r/min and 50% load indicate that the cooling pump and cooling fan together consume 7.66% of the recovered power. What's worse for the heavy load, cooling accessories may deplete of all the recovered power of the Rankine cycle system. Afterwards, effects of the condensing pressure and water feeding temperature are investigated, based on which a cooling power consumption model is established. Finally, an overall efficiency optimization is conducted to balance the electric power generation and cooling power consumption, taking condensing pressure, pressure ratio and exhaust bypass valve as major variables. The research suggests that the priority is to increase condensing pressure and open exhaust bypass valve appropriately at high speed and heavy load to reduce the cooling power consumption, while at low speed and light load, a lower condensing pressure is favored and the exhaust bypass valve should be closed making the waste heat recovered as much as possible. Within the sub-critical region, a larger pressure ratio yields higher overall efficiency improvement at medium-low speed and load. But the effects taper off at high speed and heavy load. For a given vehicular heavy-duty diesel engine, the overall efficiency can be improved by 3.37% at 1300 r/min and 25% load using a Rankine cycle system to recover exhaust energy. The improvement becomes smaller as engine speed and load become higher. | YANG Can XIE Hui ZHOU Sheng K | 2016 | Science China(Technological Sciences)2016，59，2： | 4 |
| 6 | Microstructure evolution and deformation mechanism of amorphous/crystalline high-entropy-alloy composites显示文摘High-entropy amorphous alloys present high hardness,but low tensile ductility.Here,deformation behavior of the amorphous/crystalline Fe Co Cr Ni high-entropy alloy(HEA)composite prepared by the previous experiment is investigated using atomic simulations.The result shows the partial dislocations in the crystal HEA layer,and the formation of shear bands in the amorphous HEA layer occurs after yielding.The strength of the amorphous/crystalline HEA composite reduces with increasing the thickness of the amorphous layer,agreeing with the previous experiments.The coupled interaction between the crystal plasticity and amorphous plasticity in amorphous/crystalline HEA composites results in a more homogeneous redistribution of plastic deformation to cause interface hardening,due to the complex stress field in the amorphous layer.The current findings provide the insight into the deformation behavior of the amorphous/crystalline HEA composite at the nanoscale,which are useful for optimizing the structure of the HEA composite with high strength and good plasticity. | Jia Li Haotian Chen Hui Feng Qihong Fang Yong Liu Feng Liu Hong Wu Peter K Liaw | 2020 | Journal of Materials Science & Technology2020，54，19： | 2 |
