青藏高原地区日光性皮炎的分析与展望

Analysis and Prospect of Solar Dermatitis on Qinghai-Xizang Plateau

青藏高原平均海拔4000 m以上,是世界上紫外线辐射最强的地区之一,紫外线辐射具有强烈的生物学效应,能够对生物造成普遍的影响甚至伤害。这主要与紫外线过度照射后,人体局部皮肤发生了光毒性反应有关。日光性皮炎俗称晒斑,频发于春季末夏季初,是皮肤由于中波紫外线强烈照射而引起的急性皮肤炎症。高海拔地区日光性皮炎的发病特点与同纬度平原地区相比,高原地区光照时间明显较长,日光辐射强度随着海拔的递增而增加,紫外线辐射强度比平原地区高约1.2~2.5倍,因此高海拔地区的人群更易受到影响。高原地区日光性皮炎在夏季特别多发,该病在高原地区的发病率较高,严重影响了居民的生活质量。因此,探究高原地区日光性皮炎的预防与治疗方法是有必要的。

The Qinghai Tibet Plateau has an average altitude of over 4000 m and is one of the regions with the strongest ultraviolet radiation in the world. Ultraviolet radiation has strong biological effects and can cause widespread impacts and even harm to organisms. This is mainly related to the phototoxic reaction of local skin in the human body after excessive ultraviolet radiation. Solar dermatitis, commonly known as sunburn, occurs frequently in late spring and early summer. It is an acute skin inflammation caused by intense exposure to ultraviolet radiation. The incidence characteristics of solar dermatitis in high altitude areas are significantly longer than those in plain areas at the same latitude. The intensity of solar radiation increases with altitude, and the intensity of ultraviolet ra-diation is about 1.2~2.5 times higher than that in plain areas. Therefore, people in high-altitude areas are more susceptible to the impact. Solar dermatitis occurs frequently in summer in high al-titude areas. The incidence rate of this disease is high in high altitude areas, which seriously affects the quality of life of residents. Therefore, it is necessary to explore the prevention and treatment methods of solar dermatitis in high altitude areas.
