Intense pulsed light (IPL) is an incoherent high-intensity pulsed light and early studies suggest that it might be used in photodynamic therapy (PDT). This study investigated the feasibility of using IPL combined with Hemporfin, a porphyrin-type photosensitizer. The photodynamic effects of two IPL light sources (560-1200 nm and 640-1200 nm) were determined by photobleaching of Hemporfin and Hemporfin-mediated cell killing experiments. Results showed that when combined with Hemoporfin both IPLs could generate photodynamic effects. Therefore, it is feasible to use IPL as PDT light source.
Dermoscopy is a useful tool for observing the vascular profile of port-wine stain (PWS) birthmarks. However, due to the complicity of the vascular profile, there is a lack of consensus on the classification of dermoscopic features of PWS vessels. This study investigated the potentials of deep learning-assisted methods in the classification of dermoscopy image-based of PWS vascular profiles. The classified images were used as training samples, and the RegNet network with better classification effect was selected to establish the migration learning method. The results showed that the accuracy of the RegNet network on the validation set was 82.63%. The preliminary study suggests that deep learning assisted PWS vascular contour type classification is feasible.
