Recent studies have revealed the role of microRNAs (miRNAs) in a variety of basic biological and pathological processes and the association of miRNA signatures with human diseases. Circulating miRNAs have been proposed as sensitive and informative biomarkers for multiple cancers diagnosis. We have previously documented aberrant up-regulation of miR-1(More)
OBJECTIVE Recent studies have revealed that microRNAs (miRNAs) are involved in the regulation of cardiac development, physiologic, and pathologic processes via post-transcriptional control of gene expression. The stable circulating miRNAs offer unique opportunities for the early diagnosis of several diseases. In this study, we examined the circulating(More)
BACKGROUND Pharmacologic restoration of the trafficking defects of HERG missense mutations has been documented. However, whether correction of HERG nonsense mutations is possible is unknown. OBJECTIVE The purpose of this study was to investigate the effect of aminoglycoside antibiotics on the expression of nonsense mutants expected to produce truncated(More)
OBJECTIVE To determine whether I(Na) and I(CaL) are altered in function/density in right atrial (RA) cells from dogs with chronic atrial fibrillation (cAF dogs, episodes lasting at least 6 days) and whether the changes that occur differ from those in dogs with nonsustained or brief episodes of fibrillation (nAF dogs). METHODS Using whole cell voltage(More)
To evaluate the efficacy and safety of Shensong Yangxin (SSYX) in patients with bradycardia arrhythmias, a randomized, double-blind, and placebo-controlled study was conducted. Patients with bradycardia were randomly assigned to receive either SSYX (trial group, n = 115) or placebo (control group, n = 104) for 4 weeks. ECG, 24-hour continuous ECG recording,(More)
Ca2+ cycling plays a critical role in heart failure and lethal arrhythmias. As susceptibility to sudden cardiac death is considered to be a heritable trait in general population, we have therefore investigated whether potentially functional variants of genes encoding RyR2 (ryanodine receptor 2) and the L-type Ca2+ channel are related to the risk of(More)
AIMS To investigate the relationship between electrocardiogram (ECG) parameters [J wave, fragmented QRS (fQRS), QTc, the peak-to-end interval of T wave (Tp-Te)], and sudden cardiac death (SCD) in chronic heart failure (CHF). METHODS AND RESULTS The ECGs of 1570 CHF patients, 572 cases with dilated cardiomyopathy (DCM) and 998 cases with ischaemic(More)
AIMS Clinical and animal studies suggest that beta1-adrenergic and M2 muscarinic receptor autoantibodies (beta1-AAbs and M2-AAbs) play important roles in the pathophysiological process of chronic heart failure (CHF). Removal of these autoantibodies improved haemodynamic parameters and left ventricular ejection fraction patients with CHF. The goal of this(More)
BACKGROUND The pathogenesis of idiopathic pulmonary arterial hypertension (IPAH) is unknown, and the syndrome of IPAH remains a diagnostic and therapeutic challenge. The present study investigated the disease-specific proteins that aid in the diagnosis of IPAH and thus to study their role in the disease process. METHODS A comparative proteomic analysis(More)
The purpose of this study was to evaluate whether CC-AAbs levels could predict prognosis in CHF patients. A total of 2096 patients with CHF (841 DCM patients and 1255 ICM patients) and 834 control subjects were recruited. CC-AAbs were detected and the relationship between CC-AAbs and patient prognosis was analyzed. During a median follow-up time of 52(More)
