紫外线诱导痤疮患者面部红色荧光物质分布特征

Distribution Feature of Ultraviolet-induced Red Fluorescence on Facial Skin of Patients with Acne

摘要

摘要:
目的研究痤疮患者紫外线诱导面部红色荧光物质的分布特征。
方法用SAS (skin analysis system)皮肤分析仪拍摄北京协和医院74例痤疮患者和68名健康人面部紫外光图像, 计算红色荧光物质在痤疮患者面部的检出率及其分布。
结果 74例痤疮患者中63例检出面部红色荧光物质, 检出率为85.14%;68名健康人中23名检出红色荧光物质, 检出率为33.82%, 两组比较差异有统计学意义(χ²=39.064, P < 0.005)。两组红色荧光物质在皮脂分泌量高的T区检出率较皮脂分泌量低的U区高, 两组比较差异有统计学意义(χ²=21.806, P < 0.005;χ²=15.429, P < 0.005)。
结论痤疮患者紫外线诱导红色荧光物质的出现可能与皮脂分泌有关。

Abstract:
Objective To study the distribution feature of ultraviolet (UV) -induced red fluorescence on facial skin of the patients with acne.
Methods The (skin analysis system, SAS) is used to obtain UV images of facial skins of 74 acne patients and 68 healthy individuals, and the detection rate of red fluorescence was calculated.
Results The detection rate of red fluorescence was 85.14% in 74 acne patients and 33.82% in 68 healthy individuals (χ²=39.064, P < 0.005). Additionally, it was significantly higher in T zone, where sebum secretion is higher, than in U zone, where sebum secretion is lower (χ²=21.806, P < 0.005; χ²=15.429, P < 0.005, respectively).
Conclusion UV-induced red fluorescence on facial skin of the patients with acne may be related to sebum secretion.
