SABC immunocytochemistry was employed for detection of Bax/bcl-2 protein expressions. Results：10^-5 mol/L CD437 was more effective than acitretin in inhibiting proliferation and inducing apoptosis of A375 cell after 24 h treatment, growth inhibiting ratio and apoptosis ratio（58.6%vs43.25% and 28.03%vs17.13%, P 〈 0.05 respectively）. CD437 promoted G0/G1 arrest in melanoma A375 cell, however acitretin could not. CD437 and acitretin could up-regulate the expression of Bax protein and downregulate the expression of bcl-2 protein（P 〈 0.05）. Conclusion：CD437 is more effective than acitretin in inhibiting proliferation and inducing apoptosis and cycle arrest on A375 cell, CD437 may have more potentialities than acitretin for subsidiary treatment of melanoma. Mitochondrial apoptosis pathway is partially involved in two drugs inducing apoptosis on A375 cell.展开更多

Methods： HaCaT cells were treated with different doses of acitretin for 48 h, then the changes on the transcription of FGF10 mRNA and the translation of FGF10 protein in these cells were detected by immunofluorescence and in situ hybridization assay. Results： Compared with the control group, the transcription of FGF10 mRNA and the translation of FGF10 protein were gradually decreased along with the increasing dose of aeitretin. There were significant differences between different groups （P〈0.01）. Conclusion： Aeitretin could inhibit the transcription of FGF10 mRNA and the translation of FGF10 protein in HaCaT cells. With the dose of aeitretin increased, the stains of both FGF10 mRNA and FGF10 protein in HaCaT cells are reduced.展开更多

Associated findings include nail abnormalities. A 3-year-old boy presented with porcupine-like appearance for 2 years. The lesion from the back was taken for light microscopy and electron microscopy. He was treated with acitretin (0.31 mg/d to 0.66 mg/d) for 8 years. Light microscopy and electron microscopy showed that the typical features of DD. The patient show good respond to the treatment. During 8 years treatment, the patient had dry mouth and pruritus. The skeletal abnormalities didn’t happen in the patient. The serum lipid profile, liver function and renal function within normal lever after treatment. Our findings showed that porcupine-like appearance is a unique pattern of DD. Acitretin may be a useful therapeutic agent in children with DD and less likely to cause skeletal problems.展开更多
