In this study we investigated cardiomyocyte differentiation of rat bone marrow-mesenchymal stem cells (BM-MSCs) by treating the stem cells with conditions mimicking that of myocardial infarction. The extract from infarcted rat myocardium contained the biochemical factors arising after infarction. The cardiac contraction and relaxation were simulated by(More)
OBJECTIVES Perventricular device closure of perimembranous ventricular septal defect as a novel technique has recently been described in several small series with initial experience. Further studies with larger cohorts and longer-term follow-up are needed to confirm the validity of this new approach. This report describes our recent experience with(More)
Most surgery scheduling is done 1 day in advance. Caused by lack of overall planning, this scheduling scheme often results in unbalanced occupancy time of the operating rooms. So we put forward a rolling horizon mixed integer programming model for the scheduling. Rolling horizon scheduling refers to a scheduling scheme in which cyclic surgical requests are(More)
BACKGROUND Intestinal barrier dysfunction would lead to a rigorous inflammatory reaction due to the translocation of intestinal lumen-derived bacteria and endotoxins. The aim of the present study was to investigate whether intestinal barrier dysfunction occurs in patients with acute Stanford type A aortic dissection (ATAAD) and to determine its potential(More)
BACKGROUND Both surgical repair and transcatheter closure of isolated ventricular septal defects are known to have limitations in children. This report describes the short-term results of perventricular device closure of nonmuscular ventricular septal defects without cardiopulmonary bypass in young children. METHODS Thirty patients who had nonmuscular(More)
OBJECTIVE The conventional surgical repair and transcatheter closure of muscular ventricular septal defects are known to have undesirable limitations. This communication describes the short-term results of perventricular device closure of muscular ventricular septal defects with the heart beating in 8 children with 15 muscular ventricular septal defects,(More)
BACKGROUND To evaluate the safety and efficacy of transcatheter aortic valve implantation (TAVI) for patients with aortic stenosis (AS) or pure/dominant aortic regurgitation (AR) using the J-Valve™ system. METHODS Twenty patients with isolated aortic valve disease (11 with pure/dominant AR and 9 with AS) at high risk for open-heart surgery were enrolled(More)
The Warden procedure was introduced for surgical repair of partial anomalous pulmonary venous connection to the higher portion of the superior vena cava in an attempt to decrease the incidence of postoperative sinoatrial node dysfunction and pulmonary venous obstruction. However, postoperative cavoatrial channel stenosis and obstruction up to 20% and 10%,(More)
BACKGROUD Cardiac surgery with cardiopulmonary bypass (CPB) may cause inflammatory responses, which can deteriorate the outcomes. Inflammatory cytokines, such as tumor necrosis factor (TNF)-α, interleukin (IL)-6,-8 and -10, can act as both the effector and the predictor for post-operative inflammatory responses. Plasma mitochondrial DNA (mtDNA) was found as(More)
