Background: Clearance of coronary arterial thrombosis is necessary in patients with acute ST-segment elevation myocardial infarction (STEMI) undergoing urgent percutaneous coronary intervention (PCI). There is currently no highly-recommended method of thrombus removal during interventional procedures. We describe a new method for opening culprit vessels to treat STEMI: intracoronary arterial retrograde thrombolysis (ICART) with PCI.

Background: Chronic kidney disease (CKD) is a major public health issue worldwide. Standard therapies to delay CKD progression include dietary protein restriction and administration of angiotensin-converting enzyme inhibitors (ACEi) and angiotensin receptor blockers (ARB) to help control blood pressure and confer additional renoprotective effects. Despite such interventions, CKD incidence and mortality rates continue to increase.

Objective: To investigate the accuracy of dual source computed tomography (DSCT) coronary angiography in detecton of coronary artery stenoses in patients older than 60 years.
Methods: The study was performed in 102 patients older than 60 years who were suspected of coronary artery stenoses, and without any contraindications to CT Scan and iodnated contrast agents. These patients underwent DSCT, as well as selective coronary angiography (SCA).

Background: Diabetic kidney disease (DKD) is one of the major chronic microvascular complications in diabetes mellitus, and may progress to end-stage kidney disease (ESKD). There are no definitely effective approaches for preventing, delaying or treating DKD. Small studies have shown that Prostaglandin E1 (PGE1) can improve renal blood circulation and decrease proteinuria and albuminuria.

Objective: To describe the social functions of the longevous elderly population in Dujiangyan.
Methods: A questionnaire survey was undertaken in Dujiangyan in 875 elderly people who were over 90 years old.
Results: Poor social economic status was prevalent in the longevous elderly population.
Objective: To investigate the feasibility of cultured rat ventricular myocytes taking the place of acutely enzymatic isolated myocardia for study in the pacemaker current electrophysiology.
Methods: By using patch-clamp technique, the whole-cell pacemaker currents were recorded to study the difference of pacemaker current electrophysiology between neonatal rat ventricular myocytes isolated acutely and maintained in cell culture.
Results: The cell membrane capacitances (Cm) were significantly decreased in myocardia even upon short term of cell culture.
To investigate whether stem cell transplantation affects ventricular electrophysiology in vivo, either autologous bone marrow mesenchymal stem cells or skeletal myoblast cells were transplanted via a catheter into a doxorubicin-treated failing heart. Four weeks after transplantation, electrophysiological investigation showed that transplantation of either cell type prolonged the local activation time and increased the activation time dispersion. In the stem cell transplantation groups, a positive correlation was demonstrated between activation time dispersion and the number of stem cell-derived cells in the pacing site.
