急性心肌梗死患者甲状腺激素浓度研究

目的了解AMI患者甲状腺激素水平及临床意义。方法定量检测急性心肌梗死(AMI)患者的三碘甲状腺原氨酸(T3)、游离T3(FT3)、甲状腺素(T4)、游离T4(FT4)、超敏促甲状腺激素(hs-TSH)。结果与对照组相比AMI患者血清T3降低,hs-TSH改变较为显著。结论血清T3与hs-TSH水平与AMI相关,对AMI患者病情及预后的判断有一定的临床价值。     

全外显子测序对一例甲状腺激素抵抗综合征患者THRβ基因突变的研究

目的对1例甲状腺激素抵抗综合征(resistance to thyroid hormone syndrome, RTH)患者进行临床分析及基因变异检测, 并探讨其致病机制。方法收集先证者的临床资料, 抽取先证者外周血基因组DNA进行全外显子测序筛选致病基因, 并通过Sanger测序进行验证, 同时利用生物信息学软件对变异位点进行蛋白功能分析。结果先证者表现为胸闷、心悸和持续性房颤等临床表现, 血清游离三碘甲状腺原氨酸(FT3)、游离甲状腺激素(FT4)和促甲状腺激素(TSH)水平升高, 临床高度怀疑RTH并进行基因检测。报告显示甲状腺激素受体β(THRβ)存在c.1313G>A杂合突变, 导致第438号氨基酸由精氨酸变异为组氨酸(p.R438H), 为错义突变, 遗传情况未明。根据ACMG指南, 这个变异初步判定为致病性变异。这种变异未见报道, 被认为是新发变异。结论 THRβ基因第8号外显子c.1313G>A突变可能是引起该先证者RTH的原因, 该变异c.1313G>A位于THRβ的配体结合域, 可能通过影响蛋白的三维结构及活性, 从而影响THRβ的功能。

Abstract：

Objective To explore the variation tendency of serum thyroid hormone level in the elderly aged over 80 years.Methods The 602 healthy volunteers were divided into 3 groups by age:young group (20-59 years of age,n= 226),elderly group (60-79 years of age,n= 195),and advanced age group (80-102 years of age,n=181).Fasting blood of all persons was harvested,then the levels of serum total triiodothyroxine (TT3),total thyroxine (TT4),free tri-iodothyronine (FT3),free thyroxine (FT4),thyroid-stimulating hormone (TSH) and reverse tri-iodothyronine (rT3) were determined by chemistry luminescence technique and radioimmunoassay.Statistical analysis was made by the software SPSS 13.0.Results The levels of serum FT3 and TT3 were lower in elderly group than in young group (t=2.793,3.627,P=0.005,0.000).There were significant differences in the levels of serum TT3,TT4,FT3,TSH and rT3 between young group and advanced-age group (t =10.930,6.065,15.398,- 2.933,- 5.643,all P = 0.000),also between elderly group and advanced-age group (t= 8.382,4.298,11.573,-3.383,-5.148,all P＜0.001).The levels of serum FT3,TT3 and TT4 were negatively correlated with age (r=- 0.51,-0.39 and -0.25,respectively,all P＜0.01).And the levels of serum rT3 and TSH showed positive relationships with age (r=0.32,0.12,all P＜0.01).There were no relationships between the level of serum FT4 and age.The positive rate of serum TT3,TT4,FT3,FT4,TSH and rT3 concentration beyond the reference value was 0,0,13.8%,0,6.6% and 21% in advanced-age group,respectively.Conclusions The levels of serum thyroid hormone and thyroid-stimulating hormone change with age.The levels of FT3,rT3 and TSH change obviously in the elderly aged over 80 years.It could reduce the false positive rate in clinical practice if normal reference range for serum thyroid hormone levels in different aged elderly is established.

Abstract：

Objective The purpose of this study was to investigate the change of plasma thyroxine (FT3,FT4,sTSH) in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS) and probe into the action of chronic intermittent hypoxia in the change of thyroid hormone level. Methods Following 7hours' polysomnographic examination, 116 habitual snorers were selected and divided into 4 groups according to the diffences of minSpO2 :21 snores without anoxemia,43 snores with low-grade anoxemia,30snores with moderate anoxemia, 22 snores with severe anoxemia. Step 1, plasma concentrations of FT3,FT4 and sTSH were measured. Compare the difference of FT3, FT4, sTSH among different groups.Results In different anoxemia groups, the concentrations of FT4 were significant different, and the concentrations of FT4 were also significant different among the 4 groups by SNK method. The concentrations of FT3 and TSH were no different,after tested by SNK method, there was no significant difference between the groups too. Conclusions The FT4 levels decreased with the anoxemia. We can speculate chronic intermittent hypoxia was an important cause for the change of thyroxine level.
