摘要
目的 探讨弥漫性毒性甲状腺肿（graves disease，Graves病）及桥本毒症患者在甲巯咪唑治疗前后甲状腺激素及甲状腺上动脉流速变化。 方法 x ¯ 采用病例对照研究，选取在2021年10月至2022年12月华北理工大学附属医院内分泌科就诊的Graves病（Graves病组）、慢性淋巴细胞性甲状腺炎甲状腺功能亢进病例（桥本毒症组）各45例为研究对象。分析Graves病组以及桥本毒症组患者甲状腺激素及甲状腺上动脉血流速度经甲巯咪唑治疗前后变化。满足正态分布的计量资料以±s表示，两组间均数比较采用t检验；不满足正态分布的计量资料以M（Q1，Q3）表示，两组间中位数比较采用Wilcoxon秩和检验。计数资料组间构成比比较采用χ2检验。 结果 治疗前两组间促甲状腺激素（thyroid stimulating hormone，TSH）差异无统计学意义，治疗后1个月及3个月与治疗前差值比较差异均无统计学意义（均P>0.05）。治疗前Graves病组与桥本毒症组游离三碘甲状腺原氨酸（free triiodothyronine，FT3）分别为（24.09±9.29）、（17.41±9.36）pmol/L，游离甲状腺素（free thyroxine，FT4）分别为（60.23±20.82）、（43.47±21.71）pmol/L，收缩峰值流速（peak stolie vloiy，PSV）分别为（69.53±5.70）、（52.65±4.64）cm/s，两组比较差异均有统计学意义（t值分别为3.39、3.74，Z=13.83，均P<0.001）；Graves病组与桥本毒症组治疗1个月与治疗前差值FT3分别为（-6.36±5.32）、（-12.64±9.08）pmol/L（t=4.02，P<0.001），治疗3个月与治疗前差值FT3分别为（-10.14±9.50）、（-17.80±11.17）pmol/L（t=3.51，P<0.001）；Graves病组与桥本毒症组治疗1个月与治疗前差值FT4分别为（-28.47±10.09）、（-20.57±14.48）pmol/L（t=7.01，P<0.001），治疗3个月与治疗前差值FT4分别（-47.06±20.57）、（-30.17±20.54）pmol/L（t=3.91，P<0.001）；Graves病组与桥本毒症组PSV治疗1个月与治疗前差值分别为［-13.10（-34.10，-2.60）］、［-10.50（-27.5，-0.20）］cm/s（Z=2.63，P=0.009），3个月与治疗前差值分别为［-31.40（-53.20，-12.70）］、［-19.90（-46.00，-4.70）cm/s（Z=4.40，P<0.001）］，差异有统计学意义。 结论 弥漫性毒性甲状腺肿及桥本毒症甲巯咪唑治疗后甲状腺激素水平均下降，但差异无统计学意义。弥漫性毒性甲状腺肿患者较桥本毒症患者甲状腺上动脉PSV水平下降明显。 Objective To investigate the changes of thyroid hormones and the flow velocity of superior thyroid artery in patients with Graves' disease and Hashimoto's thyrotoxicosis before and after treatment with methimazole. Methods x ¯ A case-control study was conducted to select 45 cases of Graves' disease and 45 cases of Hashimoto's thyroiditis from October 2021 to December 2022 in the Department of Endocrinology, North China University of Science and Technology Affiliated Hospital. The changes of thyroid hormone and blood flow velocity of superior thyroid artery in patients with Graves' disease and Hashimoto's thyroiditis before and after treatment with methimazole were analyzed. Measurement data satisfying normal distribution were expressed by ±s, and the mean between two groups was compared by t test. Measurement data not satisfying normal distribution were expressed by M(Q1, Q3), and the median between two groups was compared by Wilcoxon rank sum test. χ2 test was used to compare the constituent ratio of enumeration data among groups. Results There was no significant difference in thyroid stimulating hormone (TSH) between the two groups before treatment, and there was no significant difference in TSH between the two groups after 1 month and 3 months of treatment (all P>0.05). The levels of free triiodothyronine (FT3) were (24.09±9.29) pmol/L and (17.41±9.36) pmol/L in Graves' disease group and Hashimoto's thyroiditis group respectively before treatment. FT4 were (60.23±20.82) and (43.47±21.71) pmol/L, respectively, and the peak stolie vloiy (PSV) were (69.53±5.70) and (52.65±4.64) cm/s, respectively in Graves' disease group and Hashimoto's thyroiditis group respectively before treatment. There were significant differences between the two groups (t values wrere 3.39 and 3.74, Z=13.83, all P<0.001). The difference of FT3 between one month after treatment and before treatment was (-6.36±5.32) and (-12.64±9.08) pmol/L (t=4.02, P<0.001) and the difference in FT3 between 3 months of treatment and before treatment was (-10.14±9.50) and (-17.80±11.17) pmol/L, respectively (t=3.51, P<0.001) between the Graves disease group and the Hashimoto's thyroiditis group. The difference in FT4 between the Graves disease group and the Hashimoto's thyroiditis group after 1 month of treatment and before treatment was (-28.47±10.09) and (-20.57±14.48) pmol/L (t=7.01,P<0.001), and the difference of FT4 was (-47.06±20.57) and (-30.17±20.54) pmol/L (t=3.91, P<0.001) between the Graves disease group and the Hashimoto toxin group. The difference between one month after treatment and before treatment was (-13.10(-34.10,-2.60)) and (-10.50(-27.5,-0.20)) cm/s (Z=2.63, P=0.009), respectively. The difference between 3 months and before treatment was (-31.40(-53.20,-12.70)) and (-19.90(-46.00,-4.70)cm/s (Z=4.40, P<0.001)) between the Graves disease group and the Hashimoto's thyroiditis group, and the difference was statistically significant. Conclusion Thyroid hormone levels were decreased after treatment with methimazole in patients with diffuse toxic goiter and Hashimoto toxemia, but the difference was not statistically significant. The PSV level of superior thyroid artery in patients with diffuse toxic goiter was significantly lower than that in patients with Hashimoto's thyrotoxicosis.
