本文84例Grave′s甲亢患者在他巴唑治疗过程中的高血清T_3、低或正常血清T_4的发生率达50％,部分患者的临床甲状腺功能状态不完全与血清T_3水平成正相关。本文结果还提示对他巴唑治疗过程中血清T_3和T_4不一致的患者,临床甲状腺功能状态和血清TSH水平在决定他巴唑是否减量、停用以及停药后甲亢复发与否中有一定的预示意义。 In this paper, 84 cases of Grave’s hyperthyroidism patients in the process of methimazole high serum T_3, low or normal serum T_4 the incidence of 50%, some patients clinical thyroid status is not completely and serum T_3 levels are positively correlated. Our results also suggest that clinical thyroid function status and serum TSH levels in patients with inconsistent serum T_3 and T_4 during methimazole therapy may play a role in determining whether methimazole is attenuated, discontinued, and whether or not hyperthyroidism recovers after discontinuation Predictive meaning.
