The inflammatory damage caused by thrombus formation and dissolution can increase the risk of thrombotic complications on top of cell death and organ dysfunction caused by thrombus itself. Therefore, a rapid and precise thrombolytic therapy strategy is in urgent need to effectively dissolve thrombus and resist oxidation simultaneously. In this study, Ce-UiO-66, a cerium-based metal-organic framework (Ce-MOF) with reactive oxygen species (ROS) scavenging properties, encapsulated by low-immunogenic mesenchymal stem cell membrane with inflammation-targeting properties, is used to construct a targeted nanomedicine Ce-UiO-CM.

A suitable animal model bearing a close resemblance to the pathophysiological processes of humans needs to be developed. Here, we combined two risk factors to create a mouse model that mimics the pathological features of human AVS.

Methods: We used miR-21-OE, miR-21-KD, ajuba-OE and ajuba-KD plasmids to infect BMSCs. The expression of miRNA-21, ajuba, Isl1 and cTnI was detected by RT-qPCR, WB and immunofluorescence staining in groups.
Purpose: Oestrogen receptor β is believed to exert a cardioprotective effect against ischaemic injury. Nonetheless, the mechanism underlying its protective action remains to be fully elucidated. Recently, increased attention has been focused on Notch1 signalling for ameliorating cardiac ischaemic injury.

However, the effect of increasing afterload on the neonatal heart remains unknown. We performed ascending aortic constriction (AAC) in neonatal rats 8-12 hours after birth (P0, P indicates postpartum).

The aim of the study was to investigate whether PKR is involved in hydrogen peroxide (HO) induced neonatal cardiac myocytes (NCM) injury. In our study, NCM, when exposed to HO, resulted in persistent activation of PKR due to NCM endogenous RNA.

Methods: We performed a retrospective review of patients who had sustained blunt thoracic aortic injuries.
There is no agreement on whether statins influence the incidence of atrial fibrillation after coronary artery bypass grafting. We performed a meta-analysis of 12 studies that compared statins with controls. Statin therapy significantly reduced the incidence of postoperative atrial fibrillation (POAF) (odds ratio, 0.

Vascular smooth muscle cells (VSMC) undergoing a phenotypic switch to osteoblast-like cells play a key role in this process. The receptor for advanced glycation and products (RAGE) and toll-like receptors (TLRs) are all involved in various cardiovascular calcification processes.

Methods: Thirty cases undergoing cardiac surgery which included atrial septal defect neoplasty, ventricular septal defect neoplasty, mitral valve replacement and pulmonary valve coarctotomy were randomly divided into group A and group B, 15 cases in each group. Group A was given general anesthesia plus acupuncture at Neiguan (PC 6), Lieque (LU 7) and Yunmen (LU 2), and group B was given simple general anesthesia.
