摘要：目的 探讨老年患者患病时与病愈后甲状腺激素水平的变化及临床意义。方法 选择因非甲状腺疾病就诊的老年患者97例，于入院第二天晨起和病愈出院2～3个月后分别抽取空腹静脉血，检测三碘甲状腺原氨酸(T3)、四碘甲状腺原氨酸(T4)、游离三碘甲状腺原氨酸（FT3）、游离四碘甲状腺原氨酸（FT4）、促甲状腺激素（TSH），同时检测入院第二天晨起的血糖和血脂水平。结果 97例老年患者，患病时与病愈后T3、T4、FT3、FT4四种激素水平差异有统计学意义，TSH水平差异无统计学意义。结论 本研究表明，老年患者患病时甲状腺激素水平明显低于病愈后的甲状腺激素水平。

Abstract: Objective To explore the changes and clinical significance of the thyroid hormone levels in elder patients when they are sick and after the illness. Methods 97 cases of elder in-patients without thyroid diseases were selected in this study. The serum levels of T3, T4, FT3, FT4 and TSH in patients at first day of in hospital and two months after the illness were detected. The blood sugar and blood fat levels were also determined. Results The serum levels of T3, T4, FT3 and FT4 in 97 cases of elder patients had significantly difference between sickness in the hospital and after the illness (P<0.05), but no significant differences in the TSH levels (P>0.05). Conclusion This research indicates that the thyroid hormone levels in elder patients when they are sick in hospital are significantly lower than that of after the illness.
