Laser treatments do not permanently remove birthmarks known as port-wine stains, researchers have found.
研究人员发现，激光不能永久性去除葡萄酒色痣胎记。
Objective: To explore and evaluate the efficacy and safety of intense pulsed light (IPL) and pulsed dye lasers (PDL) in the treatment of purple and thick port-wine stains (PWS).
目的：探讨强脉冲光(IPL)联合脉冲染料激光(PDL)治疗紫红型和增厚型鲜红斑痣的治疗效果。
Assume that blood is distributed homogeneously over the dermal volume, instead of being enclosed in discrete vessels, and laser treatment of port wine stains has often been modelled.
设血液在整个皮肤内是均匀分布的，而不是封闭在离散的血管内，那么通常可模拟葡萄酒色痣的激光治疗。
Port wine stains affect patients on either cosmetic or functional, and even psychological aspects.
鲜红斑痣影响患者的外貌，甚至心理健康。
Photodynamic therapy is a state-of-the-art option for patients with port wine stains.
光动力疗法是鲜红斑痣患者最新的治疗选择。
Conclusions: Photosensitizer characteristics have obvious effects on photodynamic therapy for port wine stains, and mathematical simulation could show those points and their values in the round.
结论：光敏剂的特性对光动力治疗鲜红斑痣有明显的影响，数学仿真能较全面地反应这种作用的特点和意义。
