英文摘要Hepatic fibrosis (HF), as the only reversible process of chronic liver disease, remains a big diagnostic challenge. Development of noninvasive and effective methods to assess quantitatively early-stage HF is of great clinical importance. Compared with conventional diagnostic methods, near-infrared fluorescence imaging (NIR) and magnetic resonance imaging (MRI) could offer highly sensitive and spatial resolution signals for HF detection. However, precise detection using contrast agents is not possible. Superparamagnetic iron oxide (SPIO) nanoparticles have low toxicity, high sensitivity and excellent biocompatibility. Integration of Fe3O4 nanoparticles and indocyanine green (ICG), coupled with targeting ligand of integrin alpha(v)beta(3), arginine-glycine-aspartic acid (RGD) expressed on hepatic stellate cells (HSCs), were used to detect HF. Both in vivo and in vitro results showed that the SPIO@SiO2-ICG-RGD had high stability and low cytotoxicity. The biodistribution of SPIO@SiO2-ICG-RGD was significantly different between mice with HF and healthy controls. SPIO@SiO2-ICG-RGD was characterized and the results of imaging in vitro and in vivo demonstrated the expression of integrin alpha(v)beta(3) on activated HSCs. These data suggest that our SPIO@SiO(2)ICG- RGD probe could be used for the diagnosis of early-stage HF. This new nanoprobe with a dualmodality imaging approach holds great potential for the diagnosis and classification of HF.
