摘要:
目的 研究LED多波段光谱治疗对大鼠皮肤创伤愈合的影响。方法 选取50只雄性Wistar大鼠,在大鼠背部制备小面积全层皮肤缺损创面模型,随机分为模型对照(MC)组、LED治疗(LEDT)组、红外线治疗(IR)组、红光治疗(RL)组以及紫外线治疗(UV)组,每组10只。各治疗组大鼠每天暴露于对应光源下照射40 min,模型对照组放入治疗仪但不通电。每组分别于第3、7、14天处死3只大鼠,计算创面愈合率,观察HE染色结果,并检测相关蛋白表达量。结果 LEDT组、IR组、RL组和UV组创面愈合率治疗第3、7、14天愈合率均高于MC组(P<0.05);创面HE染色显示,LED多波段光谱治疗能够降低炎症反应,促进皮肤组织增殖分化,加速创伤愈合进程;LEDT组、IR组、RL组和UV组治疗第14天后EGF、VEGF、TGF-β1表达量均高于MC组(P<0.05),但LEDT与IR组TGF-β1比较,差异无统计学意义(P>0.05)。结论 LED多波段光谱治疗能够促进大鼠皮肤创伤愈合,促进皮肤再上皮化进程,提高创面中EGF、TGF-β1及VEGF蛋白表达水平。
Abstract:
Objective To study the effect of LED multi-band spectral therapy on skin wound healing in rats.Methods Fifty male Wistar rats were randomly divided into model control (MC) group, LED treatment (LEDT) group, infrared treatment (IR) group, red light treatment (RL) group and ultraviolet treatment (UV) group, with 10 rats in each group. The rats in each treatment group were exposed to the corresponding light source for 40 minutes every day, and the model control group was put into the therapeutic apparatus but not electrified. Three rats in each group were sacrificed on the 3 rd, 7 th and 14 th day respectively. The wound healing rate was calculated, the results of HE staining were observed, and the expression of related proteins was detected.Results The wound healing rate of LEDT group, IR group, RL group and UV group was higher than that of MC group on the 3 rd, 7 th and 14 th day of treatment (P<0.05). Wound HE staining showed that LED multi-band spectroscopy could reduce the inflammatory response, promote the proliferation and differentiation of skin tissue, and accelerate the process of wound healing. The expression levels of EGF, VEGF and TGF-β1 in LEDT group, IR group, RL group and UV group were higher than those in MC group after 14 days of treatment (P<0.05), but there was no significant difference in TGF-β1 between LEDT group and IR group (P>0.05).Conclusion LED multi-band spectral therapy can promote the healing of skin wounds in rats, promote the process of skin re-epithelialization, and increase the expression levels of EGF, TGF-β1 and VEGF proteins in wounds.
