The influence of partitioned profiling design based on a large-pitch highly loaded cascade is studied by numerical *** partitioned profile is mainly composed of a pressure-side convex structure near the leading edge and a suction-side convex structure at the midstream and downstream sides of the *** influence of the change in the vertex axial position and peak value of the B-line on the secondary flow control is *** this paper,air(ideal gas) is selected as the flow *** average static pressure at the outlet and the average total temperature at the inlet are kept *** γ-θ is used as the turbulence *** results show that the pressure-side convex structure suppresses the spanwise and pitchwise migration of the inlet flow by adjusting the static pressure distribution of the flow field,so the development of the pressure-side leg of the horseshoe vortex is effectively *** suction-side convex structure adjusts the static pressure distribution of the flow field and increases the included angle between the cross-flow and suction surface,so the accumulation of low-momentum fluid,the development of a corner vortex and the flow separation at the trailing edge of the suction-side surface are all suppressed near the endwall-suction ***,the energy loss coefficient of the large-pitch highly loaded cascade is decreased from 0.0564 to 0.0485,representing a 25% reduction in secondary flow losses.

Background The optimal endpoint for catheter ablation of persistent atrial fibrillation （AF） remains ambiguous. This study investigated the impact of AF termination as a procedural endpoint and the termination mode on long-term clinical outcome. Methods Two hundred and ninety-three patients who underwent stepwise ablation for persistent AF were categorized into the AF termination by ablation group and into the electrical cardioversion （CV） group. Subgroups were also analyzed based on different termination modes. Follow-up assessment included early recurrence and sinus rhythm （SR） maintenance. Results During initial ablation, 33 patients （11.3%） were directly converted to SR, 166 patients （56.7%） were converted to atrial tachycardia （AT） that subsequently restored SR with further ablation in 98 patients （33.4%）, and a total of 162 patients （55.3%） underwent cardioversion due to persistent atrial arrhythmias. Comparison between termination by ablation and termination by cardioversion in patients exhibiting AF or AT revealed that no significant difference was observed in early recurrence （38.2% vs. 43.8%, P=0.328） and SR maintenance （67.2% vs. 59.8%, P=0.198） during the （23±7） months follow-up. Even after repeat ablation, the SR maintenance continued to exhibit no statistical difference in above two groups （72.5% vs. 70.4%, P=0.686）. Further analysis of subgroups, however, demonstrated that patients with AF terminated directly to SR experienced better clinical outcomes than other subgroups （P 〈0.05）. Furthermore, atrial arrhythmias present during ablation have been implicated in prediction of recurrence mode： AF or AT （P 〈0.05）. Conclusions Termination as a procedural endpoint is not associated with favorable long-term SR maintenance in persistent AF. AF methods that convert arrhythmia directly to SR have, however, been linked with improved clinical outcomes, although conversions to AT may not be correlated. Atrial arrhythmias observed during the ablation may be used t

Background The optimal revascularization strategy in patients with heart failure with preserved ejection fraction （HFPEF） remains unclear. The aim of the present study was to compare the effects of percutaneous coronary intervention （PCI） and coronary artery bypass grafting （CABG） in patients with HFPEF. Methods From July 2003 through September 2005, a total of 920 patients with coronary artery disease （CAD） and HFPEF （ejection fraction 〉50%） underwent PCI （n=350） or CABG （n=570）. We compared the groups with respect to the primary outcome of mortality, and the secondary outcomes of main adverse cardiac and cerebral vascular events （MACCE）, including death, myocardial infarction, stroke and repeat revascularization, at a median follow-up of 543 days. Results In-hospital mortality was significantly lower in the PCI group than in the CABG group （0.3% vs. 2.5%, adjusted P=0.016）. During follow-up, there was no significant difference in the two groups with regard to mortality rates （2.3% vs. 3.5%, adjusted P=0.423）. Patients receiving PCI had higher MACCE rates as compared with patients receiving CABG （13.4% vs. 4.0%, adjusted P 〈0.001）, mainly due to higher rate of repeat revascularization （adjusted P 〈0.001）. Independent predictors of mortality were age, New York Heart Association （NYHA） class and chronic total occlusion. Conclusion Among patients with CAD and HFPEF, PCI was shown to be as good as CABG with respect to the mortality rate, although there was a higher rate of repeat revascularization in patients undergoing PCI.
