The objective of this research is to critically analyze the age and gender based variations of thyroid volume and thyroid hormone levels in the hospital based euthyroid subjects. Methodology: A total of 221 euthyroid subjects aged 1 - 86 years were selected to observe the normal thyroid size by ultrasonography at Department of Radiology and the thyroid function test values (FT3, FT4 and TSH) of 2413 euthyroid subjects aged (Results: The best fitted equations with significant correlation coefficients and p Conclusion: The thyroid size first increases and then decreases whereas the thyroxin level first decreases and then increases with aging. Left lobe volume is almost same for both genders and right lobe volume is higher in males. The thyroid size in menarche and menopause periods of females is larger than that of males. Such age- and gender-specific changes recommend the new refer-ence ranges for the normal thyroid functions.展开更多

文摘目的利用静息态功能磁共振(resting-state functional MRI,rs-fMRI)探究前额叶皮层在慢性主观性耳鸣的发生和适应中的作用。方法选取20例慢性主观性耳鸣患者和同期招募的20例健康对照组进行静息态功能磁共振成像扫描,运用分数低频振幅(fractional amplitude of low frequency fluctuation,fALFF)和基于种子点的全脑功能连接(functional connectivity,FC)指标,探测慢性主观性耳鸣患者前额叶异常脑活动与耳鸣感知脑区间的交互作用,分析前额叶异常脑活动、脑区间的功能连接改变与耳鸣临床特征间的关系。结果与健康对照组相比,慢性耳鸣患者前额叶皮层的一些特定的脑区表现出fALFF值显著降低,包括左、右内侧额上回和左、右侧额中回。其中左内侧额上回与左侧前脑岛、左侧前扣带回间的功能连接值增强,右内侧额上回与左侧颞上回、右侧额下回间的功能连接值增强,左侧额中回与右侧颞中回、右侧颞上回间的功能连接值增强,右侧额中回与左侧海马旁回、左侧顶上回、左侧辅助运动区的功能连接值增强。其中左侧额中回与右侧颞上回的功能连接程度与耳鸣致残量表评分(r=-0.627,P=0.003)及视觉模拟评分(r=-0.596,P=0.005)呈负相关。结论慢性主观性耳鸣患者的内侧前额叶和背外侧前额叶皮层存在脑功能异常变化,伴随着与突显网络、听觉皮层等脑区间功能连接强度的改变,这些异常与耳鸣的严重程度高度相关。前额叶皮层可能在耳鸣的感觉预测和听觉调控中发挥作用。
