| 1 | PIV measurements of turbulent jets issuing from triangular and circular orifice plates显示文摘The present study experimentally investigated the near-field flow mixing characteristics of two turbulent jets issuing from equilateral triangular and circular orifice plates into effectively unbounded surroundings,respectively.Planar particle image velocimetry(PIV) was applied to measure the velocity field at the same Reynolds number of Re=50,000,where Re = UeDe /with Ue being the exit bulk velocity and the kinematic viscosity of fluid,D e the equivalent diameters.The instantaneous velocity,mean velocity,Reynolds stresses were obtained.From the mean velocity field,the centreline velocity decay rate and half-velocity width were derived.Comparing the mixing characteristics of the two jets,it is found that the triangular jet has a faster mixing rate than the circular counterpart.The triangular jet entrainments with the ambient fluid at a higher rate in the near field.This is evidenced by a shorter unmixed core,faster Reynolds stress and centreline turbulence intensity growth.The primary coherent structures in the near field are found to break down more rapidly in the triangular jet as compared to the circular jet.Over the entire measurement region,the triangular jet maintained a higher rate of decay and spread.Moreover,all components of Reynolds stress of the triangular jet appear to reach their peaks earlier,and then decay more rapidly than those of the circular jet.In addition,the axis-switching phenomenon is observed in the triangular jet. | XU MinYi ZHANG JianPeng MI JianChun NATHAN G J KALT P A M | 2013 | Science China(Physics,Mechanics & Astronomy)2013，56，6： | 7 |
| 2 | Differences in atheroma between Caucasian and Asian subjects with anterior stroke:A vessel wall MRI study显示文摘Background and purpose While extracranial carotid artery stenosis is more common among Caucasians and intracranial artery stenosis is more common among Asians,the differences in atherosclerotic plaque characteristics have not yet been extensively examined.We sought to investigate plaque location and characteristics within extracranial carotid and intracranial arteries in symptomatic Caucasians and Chinese using vessel wall MRI.Methods Subjects with recent anterior circulation ischaemic stroke were recruited and imaged at two sites in the USA and China using similar protocols.Both extracranial carotid and intracranial arteries were reviewed to determine plaque location and characteristics.Results The prevalence of extracranial carotid plaque in Caucasians and Chinese was 73.1%and 49.1%,respectively(p=0.055).Prevalence of intracranial plaque was 38.5%and 69.1%in Caucasians and Chinese,respectively(p=0.02).Furthermore,42% of Caucasians and 16%of Chinese had high-risk plaque(HRP)features(intraplaque haemorrhage,luminal surface disruption)in the extracranial carotid artery(p=0.03).The prevalence of HRP features in intracranial arteries was not significantly different between the two cohorts(4%vs 11%;p=0.42).Conclusions Differences in the location and characteristics of cerebrovascular atherosclerosis were identified by vessel wall MRI in US Caucasian and Chinese subjects with recent anterior circulation ischaemic stroke.Extracranial carotid plaques with HRP features were more common in Caucasians.Intracranial plaques were more common in Chinese subjects,but no significant difference between the two cohorts in intracranial HRP prevalence was found.Larger studies using vessel wall imaging to investigate racial differences in cerebrovascular disease may inform underlying mechanisms of HRP development and may ultimately help guide appropriate therapy. | Hiroko Watase Mi Shen Binbin Sui Peiyi Gao Dong Zhang Jie Sun Niranjan Balu Daniel S Hippe Gail P Jarvik Xihai Zhao Rui Li Shuo Chen Chun Yuan Thomas S Hatsukami | 2021 | Stroke & Vascular Neurology2021，6，1： | 4 |

| 4 | Frequency and prognostic role of mucosal healing in patients with Crohn's disease and ulcerative colitis after one-year of biological therapy显示文摘AIM:To assess the endoscopic activity before and after a one-year period of biological therapy and to evaluate the frequency of relapses and need for retreatment after stopping the biologicals in patients with Crohn’s disease(CD)and ulcerative colitis(UC).METHODS:The data from 41 patients with CD and 22 patients with UC were assessed.Twenty-four CD patients received infliximab,and 17 received adalimumab.The endoscopic severity of CD was quantified with the simplified endoscopic activity score for Crohn’s disease in CD and with the Mayo endoscopic subscore in UC.RESULTS:Mucosal healing was achieved in 23 CD and7 UC patients.Biological therapy had to be restarted in78%of patients achieving complete mucosal healing with CD and in 100%of patients with UC.Neither clinical remission nor mucosal healing was associated with the time to restarting the biological therapy in either CD or UC.CONCLUSION:Mucosal healing did not predict sustained clinical remission in patients in whom the biological therapies had been stopped. | Klaudia Farkas Péter László Lakatos Mónika Szcs va Pallagi-Kunstár Anita Bálint Ferenc Nagy Zoltán Szepes Noémi Vass Lajos S Kiss Tibor Wittmann Tamás Molnár | 2014 | World Journal of Gastroenterology2014，20，11： | 2 |
