Plum-blossom needling enhanced the effect of photodynamic therapy on basal cell carcinoma.

BACKGROUND/PURPOSE: Basal cell carcinoma (BCC) often occurs on the face of middle and older aged people. Given this particular location, aminolevulinic acid-photodynamic therapy (ALA-PDT) is often applied. Specific measures in PDT treatment should be performed to increase the ALA penetration capability because the limited depth of ALA penetration may not allow for therapy to reach the tumor base. This research aims to explore a method that facilitates ALA penetration. METHODS: Three patients with BCC were subjected to four regular sessions of ALA-PDT every other week. Before the PDT treatment, super pulsed CO2 laser was used to burn a part of the lesions, and plum-blossom needle was then tapped at the lesions for three times. The fresh prepared 20% 5-ALA was coated and kept for 3 h. The lesion was irradiated with red light with 126 J/cm2 at a wavelength of 633 nm and at a rate of 100 mW/cm2 for 30 min. RESULTS: After each session of ALA-PDT, the thickness of BCC gradually decreased. After final session of ALA-PDT, the plaque became a red, painless patch. The lesions were repaired completely, and a left brown patch was left. CONCLUSION: Plum-blossom needle can be effectively applied as adjunctive treatment strategy in the development of ALA-PDT for BCC.

[Effects of MSF on melanocyte adhesion and migration in vitro].

OBJECTIVE: To investigate the Malytea Scurfpea fruit (MSF) on melanocyte adhesion and migration. METHOD: Human epidermal melanocytes were treated with MSF and Ginger respectively, then adhesion to bovine serum fibronectin-coated culture dishes was checked. Control and treated cells were also examined for migration into micropore filters coated with the same protein. RESULT: Compared with control, MSF treated melanocytes were obviously easier to adhere to the dishes and move into the filters in a dose-dependent manner. When the dose of MSF was 200 mg x L(-1), it could not reincrease melanocyte adhesion and migration. At 10 mg x L(-1), under every other concentrations of MSF, there was no marked difference among MSF-treated, Ginger-treated and untreated melanocytes (P < 0.05) when adhesion test were studied. But to migration, even at 10 mg x L(-1) MSF, there was obvious increased migration compared with MSF-untreated or Ginger-treated melanocytes (P < 0.01). CONCLUSION: MSF has effect on melanocyte adhesion and migration, which can explain, in part, the capacity of MSF to modulate melanocyte function in vitiligo lesions.
