miR-381-3p inhibits high glucose-induced vascular smooth muscle cell proliferation and migration by targeting HMGB1.

Background: Hyperglycemia increases the risk of many cardiovascular diseases (CVD), and the dysregulation of proliferation and migration in vascular smooth muscle cells (VSMCs) also participates in the pathogenesis of CVD. miR-381-3p is known to suppress the proliferation and migration of multiple human cell types. Nevertheless, the function of miR-381-3p in VSMCs remains largely indistinct.

Ablation of idiopathic ventricular arrhythmia using zero-fluoroscopy approach with equivalent efficacy and less fatigue: A multicenter comparative study.

The efficacy of a completely zero-fluoroscopy (ZF) approach for the catheter ablation of idiopathic ventricular arrhythmias (VAs) and whether it has advantages over the conventional fluoroscopy (F) approach are still unknown. The aim of this study was to compare the safety and efficacy of a completely ZF approach with those of the conventional F approach in the ablation of idiopathic VAs.We conducted a prospective study involving 7 centers in China.

Possible association between serum alkaline phosphatase concentration and thoracicacute aortic dissection.

Objectives: Alkaline phosphatase (ALP) is an enzyme that catalyzes the hydrolysis of organic pyrophosphate. Accumulating data have demonstrated that the concentration of increased ALP is associated with C-reactive protein (CRP) concentration, and inflammation was complicated in the pathogenesis of acute aortic dissection (ADD). Therefore, the aim of our study was to examine the relationship between serum ALP concentration and thoracic ADD.

Malignant potential of H22 hepatocarcinoma cells increases after recovery from IFN-γ-mediated inhibition.

IFN-γ (interferon γ) can effectively suppress tumours, but it has also been found to promote tumour progression. However, the underlying mechanisms by which it enhances malignancy have not been fully elucidated. By using a mouse model that expresses IFN-γ locally in muscle, we found that the growth potential of tumours was increased after a quick decrease of IFN-γ.
