弱激光疗法在创面愈合中的作用研究进展

Advancement in the research of effect of low level laser therapy on wound healing

弱激光疗法（low level laser therapy，LLLT）可通过促进或抑制细胞的增殖、增加或减少某些生物活性物质的释放等，达到促进组织修复、抑制炎症反应、减轻疼痛等效果，因此也被称为光调节作用（photomodulation）。目前在国外已有相关实验研究并多方位应用于临床，本文就LLLT对创面愈合的作用及机制进行综述。

Low level laser therapy （LLLT） is a thera- peutic method which regulates the biological behavior of cells with light. The effects of LLLT consist of promotion of tissue re- pair, inhibition of inflammation, and relief of pain by promoting or inhibiting the cell proliferation, increasing or decreasing the release of some bioactive substances. Therefore, LLLT is also known as photomodulation. At present, there are many relevant experimental studies of LLLT abroad, and they are also used clinically. This article reviews the effect of LLLT on wound healing.
