    Treatment group

    No treatment group

    Arm Description

    Patients with port wine stains receive PDL (1.5-10ms, 11-12.5J/cm2) with a treatment range of approximately 10*10cm2

    Patients with port wine stains have not been treated with PDL treatment

    Outcomes

    Primary Outcome Measures

    Exon mutation sequences and mutation frequencies
    In patients with nodular port wine stains, the exon mutation sequence and mutation frequency were compared between normal skin tissue (or blood), erythema and nodular tissue of the same patient.

    Secondary Outcome Measures

    Changes in the levels of cytokines in serum and skin tissues
    Changes in the levels of VEGF, FGF, HGF, PDGF, TGF-beta and other factors in serum and skin tissues before and after laser treatment

    5. Study Description

    Brief Summary
    Port wine stain (PWS) is a congenital, progressive vascular malformation of human skin involving the superficial vascular plexus that occurs in estimated 3-5 children per 1,000 live births. In childhood, PWS are flat red macules, but lesions tend to darken progressively to purple and, by middle age, often become raised as a result of the development of vascular nodules. Because most malformations occur on the face, PWS is a clinically significant problem in the majority of patients. The late-stage cobblestoning appearance of PWS subjects is comprised by not only pronounced vascular ectasia with proliferation of thin and/or thick-walled vessels and their stroma, but also numerous epithelial, neural and mesenchymal hamartomatous abnormalities. Despite these histologic observations, the specific mechanisms involved in PWS nodular formation remains unclear. In one nodular PWS subject, we found that phosphatidylinositol 3-kinases (PI3K)/protein kinase B (AKT) and phosphoinositide phospholipase C g subunit (PLC-g) were activated in both hypertrophic areas and nodules within the lesion. These observations led us to hypothesize that the PI3K pathway may play an important role in nodular formation.
