高原红细胞增多症(HAPC)是高原常见病,其病程较长,机体内环境因缺氧可发生一系列复杂变化而出现甲状腺功能的改变。本文通过测定HAPC患者甲状腺激素的水平,探讨甲状腺激素在HAPC中的变化及其临床意义。作者在海拔3 600 m选取确诊的HAPC患者61例作为实验组,其中男56例,女5例;年 High altitude polycythemia (HAPC) is a common disease in the plateau, its longer course, the body environment due to hypoxia can occur a series of complex changes in thyroid function changes. This article by measuring the level of thyroid hormone in patients with HAPC to explore the thyroid hormone in HAPC changes and its clinical significance. The authors selected 61 cases of confirmed HAPC patients at an altitude of 3600 m as the experimental group, including 56 males and 5 females;
