The purpose of this study was to test the efficacy of Berberine (Ber) on atrial fibrillation (AF) induced by acetylcholine (ACh) and explore its underlying mechanisms of action. In vivo electrophysiology experiments were performed in adult anesthetized rabbits. Single atrial myocytes were isolated from rabbit hearts and action potentials recorded using(More)
Cellular function phenotype is regulated by various microRNAs (miRs), including miR-135a. However, how miR-135a is involved in the calcification in senescent vascular smooth muscle cells (VSMCs) is not clear yet. In the present study, we first identified the significantly altered miRNAs in VSMCs, then performed consecutive passage culture of VSMCs and(More)
Sulcardine sulfate (Sul) is a novel anti-arrhythmic agent as a potential treatment for atrial fibrillation and ventricular arrhythmias. This study was conducted to investigate the pharmacokinetic profile, safety, and tolerability of Sul in healthy Chinese subjects. In this open-label, single-dose, randomized study, 10 healthy subjects were assigned to(More)
UNLABELLED Objective: In order to assess the integrative cardiopulmonary function after percutaneous coronary intervention (PCI) in patients with stable coronary artery disease (CAD), we used symptom limited maximum cardiopulmonary exercise testing (CPET). METHODS All 59 patients diagnosed stable CAD by coronary angiography and echocardiography from(More)
Sulcardine sulfate is a novel antiarrhythmic agent with mechanism of action as a multi-ion channel blocker. Preclinical studies in animal models have demonstrated that sulcardine sulfate is efficacious in atrial and ventricular arrhythmias, and consequently, leads to the prevention of sudden cardiac death. This study was conducted in healthy Chinese male(More)
Sulcardine sulfate is a newly developed candidate drug used to control arrhythmias. The aim of this research was to investigate the pharmacokinetics, bioavailability and excretion characteristics of sulcardine in animals. Sprague–Dawley rats were orally and intravenously given sulcardine at 20 and 40 mg/kg. Beagle dogs were also orally and intravenously(More)
