目的观察未经任何药物治疗急性中风患者血清甲状腺轴激素及泌乳素（ＰＲＬ）水平的变化．方法检测２２例脑出血患者和１５例脑梗塞患者血清甲状腺素（Ｔ４）、三碘甲腺原氨酸（Ｔ３）、反Ｔ３（ｒＴ３）、促甲状腺素（ＴＳＨ）及ＰＲＬ的水平，并与２７例正常人进行比较．结果急性中风患者血清Ｔ４、Ｔ３均值明显低于对照组，血清ｒＴ３、ＴＳＨ均值明显高于对照组．血清ＰＲＬ均值略高于对照组，但无统计学意义．血清Ｔ４、Ｔ３均低于对照组两个标准差者８例，其中死亡４例．结论：血清甲状腺轴激素检测有助于预测急性中风预后，低Ｔ３低Ｔ４综合征往往有恶劣的预后，应引以重视．
Objective To observe the changes of serum thyroid hormone and prolactin (PRL) levels in patients with acute stroke without any drug treatment. Methods Serum thyroxine (T4), triiodothyronine (T3), anti-T3 (rT3), thyrotropin (TSH) and PRL were measured in 22 patients with cerebral hemorrhage and 15 patients with cerebral infarction. 27 normal subjects were compared. Results The mean serum T4 and T3 levels in patients with acute stroke were significantly lower than those in the control group, and mean serum rT3 and TSH levels were significantly higher than those in the control group. Serum PRL mean slightly higher than the control group, but not statistically significant. Serum T4, T3 were lower than the control group of two standard deviations in 8 cases, of which 4 died. Conclusion: Serum thyroid hormone test can help predict the prognosis of acute stroke. Low T3 low T4 syndrome often has poor prognosis, which should be taken seriously.
