摘　　要：目的研究并分析赣南地区正常人308 nm单频准分子光最小红斑量的范围。方法以308 nm单频准分子光治疗仪为测试光源,测定来我院就诊的2013年3月~2014年2月166例健康志愿者的308 nm单频准分子最小红斑量,并研究其与不同皮肤光反应类型、性别、年龄、户外停留时间及部位的关系。结果 166例健康志愿者308 nm单频准分子光的最小红斑量（MED）均值为（907.14±96.37）m J/cm2。Ⅲ型皮肤MED值显著低于Ⅳ型皮肤（P〈0.05）;男性MED均值为（943.58±71.27）m J/cm2,女性MED均值为（952.91±52.72）m J/cm2,两者间差异无统计学意义（P〉0.05）;不同年龄组患者MED值存在差异,男性组40~49岁组测试者MED值明显大于其他年龄组MED值（P〈0.05）,女性组40~49岁组及30~39岁组测试者MED值明显大于其他年龄组MED值（P〈0.05）;不同户外停留时间测定MED值差异无统计学意义（P〉0.05）;不同部位组患者MED值存在差异,男性组前臂屈侧MED值明显大于其他部位（P〈0.05）,女性组前臂屈侧及小腿屈侧MED值明显大于其他部位（P〈0.05）。结论赣南地区正常人308 nm单频准分子光最小红斑量值范围与中国其他地区正常人MED值有差异。Objective To investigate the minimal erythema dose（MED） of 308 nm monochromatic excimer light（308 nm MEL） in healthy person of south of Jiangxi Province. Methods 166 cases of healthy volunteers were exposed to 308 nm MEL therapeutic equipment and the MED was measured in our hospital from March 2013 to February 2014,and to observe its relationship to skin type,sex,age,residence time of outdoors and the parts of the body. Results The average MED value of all subjects was（907.14±96.37） m J/cm2.The MED value in skin type Ⅲ was significantly lower than those in type Ⅳ（P0.05）.In male and female group,the average MED value were（943.58±71.27） m J/cm2 and（952.91±52.72） m J/cm2,and there was no significant difference between male and female（P 0.05）.In male group,the MED value in subjects aged from 40 to 49 was significantly higher than the others age group（P0.05）;in females group,the MED value in subjects aged from 40 to 49 and aged from 30 to 39 were significantly higher than the others age group（P0.05）.There was no significant difference of the MED value between different residence time of outdoors（P0.05）.There was significant difference of the MED value between different parts of the body,in male group,the MED value in forearm was significantly higher than the others parts of the body group（P 0.05）;in females group,the MED value in forearm and crus were significantly higher than the others parts of the body group（P0.05）. Conclusion The 308 nm MEL MED value of the subjects in south of Jiangxi Province is different from other cities of China.
