Recent evidence suggests that polydatin (PD), a resveratrol glucoside, may have beneficial actions on the cardiac hypertrophy. Therefore, the current study focused on the underlying mechanism of the PD anti-hypertrophic effect in cultured cardiomyocytes and in progression from cardiac hypertrophy to heart failure in vivo. Experiments were performed on(More)
High-mobility group box 1 (HMGB1) is a proinflammatory mediator playing an important role in the pathogenesis of cardiac dysfunction in many diseases. In this study, we explored the effects of HMGB1 on Ca(2+) handling and cellular contractility in cardiomyocytes to seek for the mechanisms underlying HMGB1-induced cardiac dysfunction. Our results show that(More)
The G protein-coupled receptor CXCR4 and its ligand stromal-cell derived factor 1 (SDF-1) play a crucial role in directing progenitor cell (PC) homing to ischemic tissue. The Src family protein kinases (SFK) can be activated by, and serve as effectors of, G proteins. In this study we sought to determine whether SFK play a role in SDF-1/CXCR4-mediated PC(More)
BACKGROUND AND AIMS Advanced glycation end products (AGEs) accumulate in diabetes and the engagement of receptor for AGE (RAGE) by AGEs contributes to the pathogenesis of diabetic cardiomyopathy. This study aims to investigate the effects of AGE/RAGE on ryanodine receptor (RyR) activity and Ca(2+) handling in cardiomyocytes to elucidate the possible(More)
KCNE2 plays an important role in maintaining cardiac electrical stability. Mutations in KCNE2 have been linked to long-QT syndrome (LQT6) and atrial fibrillation/short QT syndrome. It has been suggested that KCNE2 has the most promiscuity of function which can interact with multiple-subunits of voltage-dependent cation channels and modulate their functions.(More)
Polydatin (PD), a resveratrol glucoside extracted from the perennial herbage Polygonum cuspidatum, has been suggested to have wide cardioprotective effects. This study aimed to explore the direct antihypertrophic role of PD in cultured neonatal rat ventricular myocytes (NRVMs) and its therapeutic effects against pressure overload (PO)-induced hypertrophic(More)
BACKGROUND KCNE2 is a promiscuous auxiliary subunit of voltage-gated cation channels. A recent work demonstrated that KCNE2 regulates L-type Ca2+ channels. Given the important roles of altered Ca2+ signaling in structural and functional remodeling in diseased hearts, this study investigated whether KCNE2 participates in the development of pathological(More)
OBJECTIVE To investigate the efficiency of uterine arterial embolization in induced labour among pregnant women with placenta previa. METHODS All pregnant women (20 cases) with placenta previa who received induced labour in Taizhou First People's Hospital between 2009 and 2014 were included in this retrospective study. All cases were given rivanol(More)
OBJECTIVE The plasma level of interleukin-37 is elevated in patients with acute coronary syndrome, however, its function during the onset and progress of the disease remains unclear. This study aimed to investigate the clinical significance of IL-37 in acute coronary syndrome and its underlying mechanism. METHODS 124 patients with acute coronary syndrome(More)
