Abstract The purpose of this research was to evaluate HSYA’ effects and mechanisms to improve Scars Induced by Anticoagulant Injection by vivo and vitro study. New Zealand rabbits were divided into Normal control (NC), Anticoagulant, Anticoagulant+HSYA-Low, Anticoagulant+HSYA-Middle and Anticoagulant+HSYA-High. Measuring TGF-β1 and IL-1β concentration by Elisa assay; evaluating pathology and fibrosis level by HE and Masson staining, measuring collage I, collage III, TLR4 and NF-κB(p65) protein expression by IHC assay. Relative gene expression (Collage I, Collage III, TLR4 and NF-κB(p65)) were evaluated by RT-qPCR assay. Relative proteins expression (Collage I, Collage III, TLR4 and NF-κB(p65)) were evaluated by WB assay. And using TGF-β1 to stimulate cell to make cell model. Compared with NC group, TGF-β1 and IL-1β concentration were significantly increased (P < 0.001); The pathology and fibrosis level were significantly deteriorated, meanwhile, Collage I, Collage III, TLR4 and NF-κB(p65) proteins and gene expression were significantly up-regulation in Anticoagulant group (P < 0.001). With HSYA supplement, TGF-β1 and IL-1β concentration were significantly depressed, Pathology and fibrosis levels were significantly improved, Collage I, Collage III, TLR4 and NF-κB(p65) proteins and gene expressions were significantly improved with dose-dependent (P < 0.05). HSYA could improve anticoagulant injury induced subcutaneous scar via regulation TLR4/NF-κB(p65).
