The effectiveness of current drug treatment for NP is still unsatisfactory due to its side effects, addiction and withdrawal. In recent years, researchers have begun to develop nano-drug delivery systems for the diagnosis and treatment of NP diseases.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We developed a disulfide-bonded magnetic mesoporous silica dual-drug delivery system consisting of <jats:italic>curcumin<\/jats:italic> (<jats:italic>Cur<\/jats:italic>) and a calcitonin gene-related peptide (CGRP) antagonist (CGRPi), and characterized by electron microscopy, Dynamic Light Scattering (DLS), Zeta, specific surface area and pore size detection. At the cellular level, the biocompatibility of CGRPi@<jats:italic>Cur<\/jats:italic>@Fe<jats:sub>3<\/jats:sub>O<jats:sub>4<\/jats:sub>@mSiO<jats:sub>2<\/jats:sub>-PEG (FMCC) nanoparticles were tested by CCK-8 and dead\/alive staining kit in BV2 cells; Inflammation levels and oxidative stress were measured by enzyme linked immunosorbent assay (ELISA) in lipopolysaccharide (LPS)-induced BV2 neuroinflammation model. <jats:italic>In vivo<\/jats:italic>, chronic constriction injury (CCI) model was constructed, and the effect of FMCC on pain behavior of CCI mice was detected by von Frey filaments test and thermal hyperalgesia; The effects of FMCC on the anti-inflammatory and oxidative stress of CCI were determined by pathological tests (HE and ROS staining), RT-PCR and ELISA.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>FMCC had good biocompatibility and could be taken up by BV2 cells.
