摘要： 【摘要】 目的 研究氨基酮戊酸-光动力疗法（ALA-PDT）对尖锐湿疣组织中血管内皮生长因子（VEGF）和增殖细胞核抗原（PCNA）表达的影响。方法 2016年10月至2017年9月在郑州大学第一附属医院皮肤科门诊收集56例尖锐湿疣患者ALA-PDT治疗前及第1次治疗后1周皮损各1份，采用免疫组化SP法检测尖锐湿疣组织角质形成细胞中VEGF及PCNA的表达情况。分别采用χ2检验和秩和检验分析治疗前后VEGF与PCNA蛋白表达率和表达强度的差异，采用Spearman分析检验VEGF及PCNA蛋白表达的相关性。结果 ALA-PDT治疗前尖锐湿疣组织角质形成细胞中VEGF和PCNA表达率分别为71.43%（40/56）、73.21%（41/56），治疗后分别为44.64%（25/56）、41.07%（23/46）。治疗前后VEGF和PCNA的表达率（χ2值分别为8.25、11.81， 均P < 0.05）及表达强度（H值分别为11.29、12.22，均P < 0.05 ）差异均有统计学意义。ALA-PDT治疗前后尖锐湿疣组织VEGF与PCNA表达呈正相关（rs值分别为0.202、0.273，均P < 0.05）。结论 ALA-PDT治疗后尖锐湿疣组织中VEGF和PCNA表达下降，这可能是其治疗尖锐湿疣的作用机制之一。

Abstract: 【Abstract】 Objective To evaluate the effect of aminolevulinic acid-based photodynamic therapy （ALA-PDT） on the expression of vascular endothelial growth factor （VEGF） and proliferating cell nuclear antigen （PCNA） in condyloma acuminatum （CA） tissues. Methods A total of 56 patients with CA were enrolled from Department of Dermatology, The First Affiliated Hospital of Zhengzhou University from October 2016 to September 2017, and skin lesions were obtained before and 1 week after the first ALA-PDT treatment. Immunohistochemical SP method was used to determine the expression of VEGF and PCNA in keratinocytes in the CA tissues. Chi-square test and rank sum test were carried out to analyze differences between pre- and post-treatment expression rate and intensity of VEGF and PCNA, and Spearman correlation analysis was conducted to analyze the correlations between the protein expression of VEGF and PCNA. Results The expression rates of VEGF and PCNA in keratinocytes in the CA tissues were 71.43% （40/56） and 73.21% （41/56） respectively before ALA-PDT, and 44.64% （25/56） and 41.07% （23/46） respectively after ALA-PDT. There were significant differences between pre- and post-treatment expression rate and intensity of VEGF and PCNA（expression rate: χ2 = 8.25, 11.81 respectively, both P < 0.05; expression intensity: H = 11.29, 12.22 respectively, both P < 0.05）. The expression of VEGF was positively correlated with the expression of PCNA in the CA tissues before and after the ALA-PDT treatment （rs = 0.202, 0.273, respectively, both P < 0.05）. Conclusion The expression of VEGF and PCNA decreased in CA tissues after ALA-PDT treatment, which may be one of the mechanisms underlying the treatment of CA with ALA-PDT.
