OBJECTIVE The aim of the present study was to investigate whether pterostilbene could modulate the TLR4/NF-κB signaling, reduce neutrophil accumulation and TNF-α induction in an ischemia/reperfusion injured rat heart model. MATERIALS AND METHODS Rats were randomly exposed to sham operation, myocardial ischemia and reperfusion (MI/R), MI/R + pterostilbene,(More)
BACKGROUND Hyperkinetic pulmonary arterial hypertension (PAH) is a common complication in congenital heart disease, and affects operations, indications, and prognoses for patients. Gene-based stem cell transplantation is an alternative treatment that can attenuate PAH. METHODS Hyperkinetic PAH rabbit models were successfully established, using common(More)
OBJECTIVE To present our experience in transcatheter closure of calcified patent ductus arteriosus (PDA) in older adult patients, which has rarely been reported. PATIENTS From 2009 to 2014, a total of 16 patients (median age 58 years) with calcified PDA underwent transcatheter closure in our center. All patients were symptomatic with major symptoms being(More)
Hyperkinetic pulmonary arterial hypertension (PAH) severely influences the success of operation for congenital heart disease and deteriorates the prognosis of disease. Adipose-derived stromal cell (ADSC) is a good alternative multipotent stem cell for regeneration medicine. PAH rat models were established by arteriovenous shunt and ADSCs were isolated,(More)
Percutaneous intervention is preferred over reoperation for the treatment of iatrogenic membranous ventricular septal defects (VSDs). During the standard percutaneous procedure, an arterio-venous loop is used for occluder deployment, entailing the risk of device impingement on the prosthetic aortic valve, which may cause serious complications or even death.(More)
Polypropylene carbonate (PPC), a biodegradable aliphatic polyester, exhibits one particular advantage over other polyesters, which is that following degradation in vivo, it primarily produces H2O and CO2, causing minimal side effects. Although PPC exhibits limited mechanical strength, and is therefore not able to serve as a scaffold to support tissue(More)
PURPOSE To investigate whether inhalation of ethyl pyruvate (EP) encapsulated with poly(ethylene glycol)-block-lactide/glycolide copolymer nanoparticles (EP-NPs) can prevent the development of shunt-flow-induced hyperkinetic pulmonary arterial hypertension (PAH) in a rat model. MATERIALS AND METHODS Rats were separated into five groups: blank (ie, no(More)
