The invention discloses an application of glycogen synthase kinase 3beta in preparation of antihypertensive drugs. The GSK3beta gene is inserted into a GV652 plasmid and is packaged into an adeno-associated virus, so that specific overexpression of the adeno-associated virus in vascular endothelial cells is realized, and the adeno-associated virus is used for preparing medicines for treating hypertension. It is found for the first time that overexpression of GSK3beta in endothelial cells can improve the endothelial dependent relaxation function and reduce blood pressure. Mechanism research shows that serine 9-site phosphorylation of GSK3beta can activate an AKT-eNOS signal channel and promote release of nitric oxide, so that the endothelial function is improved, and the antihypertensive effect is achieved. Furthermore, glycine can promote phosphorylation of the GSK3beta Ser9 site, and AKT-eNOS signal activation and NO generation are enhanced. The invention provides a novel anti-hypertension gene therapy strategy for regulating and controlling an endothelial function based on a GSK3beta gene.

A system and method for prolonged organ preservation and real-time ex-vivo organ assessment. The organ perfusion and assessment system includes three components: A full cardiac output circuit, a resuscitation and low flow circuit, and an organ indexing stack to perform real-time hemodynamic ex-vivo organ assessment. A containment vessel maintains sterility and allows for complete echo-analysis. The slope of preload recruitable stroke work (PRSW) and other load-independent and load-dependent assays are used to stratify donor heart function. The best assessment of systolic function and therefore transplant suitability appears to be PRSW; the best systolic function is seen with full support of a donor heart. The best assessment of diastolic dysfunction appears to be Tau; the best diastolic function is also seen with full support of a donor organ. Load independent assessments appear to be highly repeatable and should identify currently discarded human donor hearts that are actually suitable for transplantation.
