Popis: Background The effect of 5-aminolevulinic acid photodynamic therapy on keratinocyte proliferation and apoptosis in condyloma acuminatum tissues was evaluated. Methods An immunohistochemical method and TdT-mediated dUTP nick end labeling were performed to detect the positive expression of the keratinocyte proliferation-related gene Ki-67 and apoptosis, respectively, in condyloma acuminatum tissues. Results Of 52 cases, 44 showed positive expression of Ki-67 in condyloma acuminatum keratinocytes before the treatment, with a positive expression rate of 84.62% (44/52), an expression strength of mostly ++ − +++, and a Ki-67 proliferation index of 80.26 ± 5.07%. After treatment, 22 cases showed positive expression of Ki-67 in condyloma acuminatum keratinocytes, with a positive expression rate of 42.31% (22/52), an expression strength of mostly − − ++, and a proliferation index of 42.67 ± 3.06%. The differences in the positive expression rate, expression strength, and proliferation index in the before- and after-treatment groups were statistically significant (χ2 = 20.070, P Conclusion 5-Aminolevulinic acid photodynamic therapy can inhibit the proliferation and promote the apoptosis of keratinocytes, and represents an effective mechanism for treating condyloma acuminatum.
