【Objective】 To observe the effects of tissue-type plasminogen activator(t-PA) gene plasmid packaged with albumin nanoparticles crosslinked to albumin ultrasound microbubbles in prevention of in-stent thrombosis and vascular intimal hyperplasia after stenting intervention.【Methods】 A rabbit iliac arterial model of in-stent thrombosis with intimal hyperplasia was made by deendothelialization followed by the bare-mental stent implantation. Eukaryotic-expression t-PA gene plasmid packaged with albumin nanoparti...
