Balloon Deflation Strategy during Primary Percutaneous Coronary Intervention in Acute ST-Segment Elevation Myocardial Infarction: A Randomized Controlled Clinical Trial and Numerical Simulation-Based Analysis.

Background: Primary percutaneous coronary intervention (PCI) is the best available reperfusion strategy in patients with acute ST-segment elevation myocardial infarction (STEMI). However, PCI is associated with a serious problem known as no-reflow phenomenon, resulting in poor clinical and functional outcomes. This study aimed to compare the influences of different balloon deflation velocity on coronary flow and cardiovascular events during primary PCI in STEM as well as transient hemodynamic changes in in vitro experiments.

[Lipid-lowering effect of seven traditional Chinese medicine monomers in zebrafish system].

The present study aimed to study lipid-lowering effect of seven traditional Chinese medicine monomers in zebrafish system. Zebrafish were fed with high fat diet to establish a hyperlipemia model, then fasted and bathed with seven traditional Chinese medicine monomers stigmasterol, triacontanol, chrysophanol, vanillic acid, shikimic acid, polydatin and oleanolic acid respectively. The oil red O staining was used to detect the blood lipids of zebrafish.
