摘要:

以白藜芦醇(RES)和聚乙烯吡咯烷酮(PVP)为原料, 通过纳米沉淀法制备了尺寸均一的RES-PVP球形纳米颗粒(RES-PVP NPs); 将其作为纳米药物负载在以透明质酸为基质的可溶性微针(MNs)中, 制备了载药微针(MN-NPs). 微针载药后仍然保持了较高的机械强度, 能够满足穿透人瘢痕组织皮肤的需要. MN-NPs中的RES-PVP NPs能够诱发人瘢痕疙瘩成纤维细胞的凋亡并抑制其迁移. 体内实验结果表明, MN-NPs能够有效抑制瘢痕疙瘩的生长, 展现出治疗瘢痕疙瘩的能力. 本文提出的以载药微针实现白藜芦醇纳米药物的透皮给药并治疗瘢痕疙瘩的方法是可行的, 具有良好的应用前景.

Abstract:

By using resveratrol(RES) and polyethylpyrrolidone(PVP) as raw materials, RES-PVP spherical nanoparticles(RES-PVP NPs) with uniform size were prepared by nano-precipitation method. Then the RES-PVP NPs were loaded into soluble microneedles(MNs) based on hyaluronic acid to prepare the nanodrug-loaded microneedles MN-NPs. The microneedles still maintain high mechanical strength after drug loading, which can meet the needs of penetrating the skin of human scar tissue. The RES-PVP NPs in MN-NPs can induce the apoptosis of human keloid fibroblasts and inhibit their migration. In experiments in vivo, MN-NPs can effectively inhibit the growth of keloid, showing the ability in keloid treatment. The method proposed in this work of transdermal delivery of resveratrol nanodrug using drug-loaded microneedles to treat keloid is feasible, and has good application prospect.

Key words: Resveratrol, Nanodrug, Microneedle, Keloid
