OBJECTIVE To sought to engineer and characterize a biodegradable nanoparticles (NPs) containing rapamycin which use poly (lactic-co-glycolic) acid (PLGA) as the carrier matrix and to assess its in vivo release characteristics by local drug delivery system intravascularly. METHODS Rapamycin-loaded PLGA NPs were prepared by an emulsification/solvent(More)
BACKGROUND Reduction of cholesterol and inflammation can be achieved by administration of a statin. Xuezhikang, an extract of cholestin, available from Chinese red yeast rice, could effectively modify the lipid profile. However, limited information is available regarding rapid effects of Xuezhikang on plasma C-reactive protein (CRP) and the lipid profile in(More)
OBJECTIVE To investgate the effects of rapamycin(RPM)and RPM-loaded poly(lactic-co-glycolic)acid(PLGA)nanoparticles(NPs)on the apoptosis of human umbilical arterial vascular smooth muscle cells(HUASMCs)in vitro and expression of bcl-2 and p27(kip1) protein. METHODS HUASMCs were cultured in vitro and divided to RPM and RPM-PLGA-NPs groups treated at 3(More)
OBJECTIVE To determine whether intramural administration of rapamycin (RPM)-loaded polylactic-polyglycolic acid (PLGA) nanoparticles (NPs) can reduce intimal thickening and affect the mRNA expressions of matrix metalloproteinase (MMP)-2, tissue inhibitor of metalloproteinase (TIMP)-2 and p27(kipl) in a coronary injury-stenosis model of minipigs. METHODS(More)
OBJECTIVE To evaluate the effects of rapamycin (RPM)-loaded poly (lactic-co- glycolic) acid (PLGA) nanoparticles (NPs) on the proliferation, distribution of cell cycle, and expression of p27 protein in human umbilical arterial vascular smooth muscle cell (HUASMC) in vitro. METHODS The primarily culture model of HUASMC was successfully established by(More)
