摘要
目的:探讨红光照射对难治性创面的创缘组织中血管内皮细胞生长因子(vascular endothelial growth factor,VEGF)的表达及治疗难治性创面的临床效果。方法:收集2008年6月-2010年12月因难治性创面入住笔者单位治疗的40例患者,按治疗方法分为红光照射治疗组20例和常规治疗组20例。常规治疗组患者创面以0.5%碘伏与水胶体敷料换药。治疗组在常规治疗的基础上加用红光照射。于治疗后第7天、14天、21天切取创缘组织,研究红光照射对创缘组织中VEGF的影响,并比较两组患者的创面愈合率和愈合时间。结果:临床实验中,治疗组创缘组织中的VEGF含量明显高于对照组(P<0.01);治疗组创面愈合率明显高于对照组(P<0.01);治疗组的愈合时间低于对照组(P<0.05)。结论:红光照射能显著提高创缘组织中VEGF含量,减少创面愈合时间,促进愈合。
Objective：To study the effect of red LED irradiation on the vascular endothelial growth factor（VEGF） expression in wounded tissue and its clinical effects.Methods：Immunohistochemical staining was used to detect the expression of VEGF in the wounded tissue in different time,the rate of wound surface healing and time of wound healing were also observed.Results：VEGF was expressed in the process of wound healing.The expression of VEGF in red LED irradiation group was higher than that in the control group.Conclusion：red LED irradiation could increase the expression of VEGF in the wounded tissue and promote wound healing.
