Abstract (original English)

Lower back pain (LBP) is a common and frequent clinical condition, and intervertebral disc degeneration (IDD) is recognized as the leading cause of LBP, typically manifested by increased nucleus pulposus cell (NPC) senescence and death. In recent years, the treatment of IDD with stem cell injections has had great potential compared to surgical treatment. Combining the two may achieve better results, as BuShenHuoXueFang (BSHXF) is an herbal formula that improves the survival rate of transplanted stem cells and enhances their efficacy. We aimed to qualitatively and quantitatively analyze BSHXF-medicated serum and investigate the molecular mechanism of BSHXF-mediated serum in promoting the differentiation of adipose mesenchymal stem cells (ADSCs) into NPCs and delaying the senescence of NPCs by regulating the TGF-β1/Smad pathway. In this study, an ultrahigh-performance liquid chromatography-quadrupole-time-of-flight mass spectrometer (UPLC-Q-TOF-MS) was used to establish a method for the analysis of rat serum samples to track the active components in vivo; the oxidative damage model of NPCs was induced by T-BHP, and a Transwell chamber was used to construct a coculture system of ADSCs and NPCs. Flow cytometry was used to determine the cell cycle; SA-β-Gal staining was used to assess cell senescence; ELISA was used to detect IL-1β, IL-6 inflammatory factors, CXCL-1, CXCL-3, CXCL-10
