RESUMO
Objective To investigate the expression of platelet-derived growth factor B(PDGF-B) and PDGFR-α mRNA in the skin lesion of recurrent condyloma acuminatum(CA) and to explore its relationship with recurrent condyloma acuminatum.Methods The expressions of PDGF-B and PDGFR-α mRNA in the lesions of recurrent CA and Nonrecurrent CA were investigated by Real-Time-PCR,and the normal foreskins weretaken as controls.Results The PDGF-B and PDGFR-α mRNA levels in the re current CA group and non-recurrent CA group were significantly higher than those in the normal control group,the differences were statistically significant(P＜0.05).The expressions of PDGF-B and PDGFR-α mRNA in the recurrent CA group were higher than those in the non-recurrent CA group(P＜0.01).Furthermore,the expressions of PDGF-B and PDGFR-α mRNA before treatment in the recurrent CA group were higher than those after treatment(P＜0.01).Conclusion PDGF-B and PDGFR-α mRNA might haue a certain relation with CA recurrence.
