Hypertrophic scar is an abnormal fibrous proliferative disease that occurs after deep cutaneous injury, which not only affects aesthetics and function but also has negative psychological effects on the patients. However, the mechanism of hypertrophic scar formation has not been fully elucidated, and its clinical treatment is complex with a high rate of recurrence and no radicle cure. Intervention based on molecular targets will likely be the future direction for the prevention and treatment of hypertrophic scar. In this article, we review the specific roles and mechanisms of drug-targeted interventions in hypertrophic scar formation, including general drugs, cytokines, immunomodulators, herbal extracts, exosomes, and nanomaterials, in the context of advances in both basic and clinical research at home and abroad.
增生性瘢痕是皮肤深层损伤后出现的纤维异常增生性疾病，不但影响美观与功能，还会对患者心理产生不良影响。然而增生性瘢痕的发生机制尚未被完全阐明，其临床治疗复杂且复发率高，尚无确切的根治方法。基于分子靶点的干预，将可能是未来预防和治疗增生性瘢痕的方向。该文结合国内外相关基础研究与临床研究进展，围绕一般药物、细胞因子、免疫调节剂、中药提取物、外泌体、纳米材料等药物靶向干预增生性瘢痕的具体作用和机制进行综述。.
