Bovine pericardium has been extensively applied as the biomaterial for artificial heart valves and may potentially be used as a scaffold for tissue-engineered heart valves after decellularization. Although various methods of decellularization are currently available, it is unknown which method is the most ideal one for the decellularization for bovine(More)
This study focused on the synthesis, characterization and cytocompatibility of a biodegradable polymer by the cross-linking from poly(ethylene glycol-co-lactide) dimethacrylate (PLEGDMA), polyethylene glycol diacrylate (PEGDA) and N-isopropylacrylamide, where PLEGDMA was synthesized by ring-opening oligomerization of poly(ethylene glycol) with different(More)
To evaluate the clinic outcome of off-pump coronary bypass grafting (OPCABG) of patients with coronary heart disease and chronic obstructive pulmonary disease, we collected and analyzed 1998-2002 data on 28 patients with these two diseases who had received off-pump coronary bypass operation in our hospital, and compared with data on those who also had the(More)
OBJECTIVE To investigate the effects of different subtypes IFN alpha (IFN alpha2b, IFN alpha2a, and IFN alpha1b) transduction molecular STAT1, STAT2, IFNAR, PKR, and RNase L, and to study the differences of their antiviral effects and to evaluate the key signaling transduction molecules. METHODS (1) After HepG2 cells were treated with IFN alpha2b, IFN(More)
OBJECTIVE To study the effects of ketamine anesthesia and surgery on cognition and synaptic structure in hippocampus of senile rats. METHODS Fifty-six rats aged 18 months were randomly divided into 3 groups: Groups C (control group), A (ketamine 40 mg/kg, i.p.) and O (ketamine anesthesia & splenectomy). Morris water maze test was used to observe cognition(More)
The present paper's main work is firstly preparing a single layer and a large area polystyrene microspheres mask, with 117, 350 and 500 nm in diameter, and then depositing a layer of zinc oxide thin film on the mask board by RF magnetron sputtering technique, using nanospheres lithography technique to remove the polystyrene spheres by soaking with(More)
OBJECTIVE To evaluate the surgical clinical results of hypertrophic obstructive cardiomyopathy. METHODS We retrospectively collected data on 24 patients who underwent surgical management in the past ten years in two hospitals in China and Madras Medical Mission in India. Myomectomy was carried out on all patients. Among them 3 patients underwent mitral(More)
OBJECTIVE To investigate the anti-HBV effect of fusion protein thymosin alpha1-interferon alpha (TA1-IFN) in vitro and to compare its effect with a combination of interferon alpha and thymosin alpha1. METHODS After 2.2.15 cells were seeded for 24 hours, drugs of five serial concentrations (8000, 4000, 2000, 1000, 500 U/ml) were added to the wells, then(More)
