摘要 目的:探讨大鼠烧伤和热压伤中变性真皮miRNA-199a-5p表达量随时间的变化情况。方法:用控温烫伤仪制作皮肤烧伤模型和热压伤模型,设置阴性对照组,用qRT-PCR检测不同的时间烫伤和热压伤部位变性真皮中的miRNA-199a-5p相对表达量。结果:各模型组变性真皮中miRNA-199a-5p相对表达量较正常组织中的相对表达量呈先下调后上调趋势,14 d时miRNA-199a-5p相对表达量上调具有显著差异(P<0.05)。结论:miRNA-199a-5p表达和变性真皮的增殖和迁移调控相关,损伤早期表达量的下调,促进变性真皮恢复正常功能,表达量的上调则促进细胞增殖和迁移,为热压伤创面修复机制的探讨提供新思路。
