OBJECTIVES This study explored the novel strategy of hypoxic preconditioning of bone marrow mesenchymal stem cells before transplantation into the infarcted heart to promote their survival and therapeutic potential of mesenchymal stem cell transplantation after myocardial ischemia. METHODS Mesenchymal stem cells from green fluorescent protein transgenic(More)
AIM Mesenchymal stem cells (MSC) are a promising candidate for cardiac replacement therapies. However, the majority of transplanted MSC are readily lost after transplantation because of poor blood supply, ischemia-reperfusion, and inflammatory factors. We aimed to study the effects of hypoxia preconditioning (HPC) on hypoxia/reoxygenation-induced apoptosis(More)
BACKGROUND Cardiomyocyte apoptosis takes place at an early stage after myocardial infarction (MI). Therapy with mesenchymal stem cells (MSCs) is reported to reduce apoptosis. OBJECTIVES To determine whether anoxic preconditioning (AP) could enhance the antiapoptotic effect of MSCs. METHODS Cultured cardiomyocytes were treated with Dulbecco's modified(More)
OBJECTIVES The intention of the PEPCAD China ISR (A Prospective, Multicenter, Randomized Trial of Paclitaxel-Coated versus Paclitaxel-Eluting Stent for the Treatment of Drug-Eluting Stent In-Stent Restenosis) was to demonstrate the efficacy of paclitaxel-coated balloon (PCB) angioplasty in a non-European patient population with coronary drug-eluting stent(More)
IMPORTANCE Uncertainty remains about the efficacy of folic acid therapy for the primary prevention of stroke because of limited and inconsistent data. OBJECTIVE To test the primary hypothesis that therapy with enalapril and folic acid is more effective in reducing first stroke than enalapril alone among Chinese adults with hypertension. DESIGN, SETTING,(More)
The human major histocompatibility complex (MHC) region has been shown to be associated with numerous diseases. However, it remains a challenge to pinpoint the causal variants for these associations because of the extreme complexity of the region. We thus sequenced the entire 5-Mb MHC region in 20,635 individuals of Han Chinese ancestry (10,689 controls and(More)
Cytochrome P450 epoxygenase 2J2 (CYP2J2) metabolizes arachidonic acids to form epoxyeicosatrienoic acids (EETs), which possess various beneficial effects on the cardiovascular system. However, whether increasing EETs production by CYP2J2 overexpression in vivo could prevent abdominal aortic aneurysm (AAA) remains unknown. Here we investigated the effects of(More)
OBJECTIVE This study was designed to determine the optimal time point for bone marrow mesenchymal stem cell (MSC) transplantation after myocardial infarction (MI). METHODS MSCs from donor rats were labeled with DAPI before transplantation. The animals underwent MI by ligation of left anterior descending coronary artery, and received intramyocardial(More)
OBJECTIVE Recent experimental and clinical observations have suggested that cell transplantation could be of therapeutic value for the treatment of heart failure. This study was performed to explore the efficacy and safety of intracoronary autologous mesenchymal stem cells (MSCs) transplantation for treating patients with idiopathic dilated cardiomyopathy.(More)
Transplantation using stem cells including bone marrow mesenchymal stem cells (BMSCs) is emerging as a potential regenerative therapy after ischemic attacks in the heart and brain. The migration capability of transplanted cells is a critical cellular function for tissue repair. Based on our recent observations that hypoxic preconditioning (HP) has multiple(More)
