方法:正常对照组为健康志愿者20例,其中男4例,女16例。实验组为2009年1月至2010年1月经河北医科大学第二医院确诊的未经治疗的甲状腺功能减退症患者40例(排除继发性甲状腺功能减退症及慢性肝病或肾上腺疾病引起的甲状腺功能减退症),患者病程<3个月,按甲状腺功能减低程度分为亚临床甲减组及临床甲减组(亚临床甲减组血清学检查:TSH↑,而FT4、FT3在正常参考范围内,临床甲减组血清学检查: TSH↑,FT3↓,FT4↓),每组病人20例,临床甲减组患者抗甲状腺过氧化物酶抗体>1300U/ml,均为桥本甲状腺炎导致的临床甲减。所有受检者均在河北医科大学第二医院检测甲状腺功能,随即进行超声波检查。实验仪器采用飞利浦公司的IU22彩色多普勒超声诊断仪,高频探头,探头频率为5～12MHz,取样容积约1.0mm,声束与血流束方向夹角<60°,安静状态下,患者取仰位,头略向后仰,充分暴露颈部。用二维超声常规观察甲状腺声像图特征并测量双侧甲状腺长径(D1)、横径(D2)、厚径(D3)各数值均连续测3次取平均值。应用彩色多普勒血流图观察甲状腺内血流分布情况,测量甲状腺上动脉管径。应用频谱多普勒于甲状腺上动脉入甲状腺上极前5～10mm处测量其收缩期最高流速(Vmax)及阻力指数(RI),连续测3次取平均值。将各组两侧叶甲状腺上动脉管径,Vmax、RI相加,求单侧叶各指标的平均值。根据V单=(∏/6)×D1×D2×D3,计算甲状腺单侧叶体积V=(VL+VR)/2。
应用SPSS11.5统计软件对所得数据进行统计分析。数据用均数±标准差表示,多组间比较用方差分析和F检验,两两比较用q检验,相关性比较做相关分析,计数资料用卡方检验,以P<0.05为差异有统计学意义。

亚临床甲减组与临床甲减组甲状腺各径线及体积与对照组相比较差异均有统计学意义(P<0.05),均较对照组增大。亚临床甲减与临床甲减组比较,除甲状腺厚径差异无统计学意义(P>0.05)外,余甲状腺径线及体积差异均有统计学意义(P<0.05)。
1.2彩色多普勒超声特征
1.2.1甲状腺上动脉管径

1.2.2甲状腺组织内血流特征
对照组甲状腺组织内血流信号不丰富,可见稀疏分布的点、束状血流信号。亚临床甲减组、临床甲减组患者中绝大多数甲状腺腺体内血流信号增多,部分患者甲状腺内布满彩色血流。亚临床甲减组及临床甲减组与对照组比较差异有统计学意义(P<0.05),亚临床甲减组与临床甲减组之间比较差异无统计学意义(P>0.05)。

2相关性研究
2.1甲状腺上动脉收缩期最高流速(Vmax)与甲状腺单侧叶体积(V)的相关性研究
分别将亚临床甲减组、临床甲减组的甲状腺上动脉收缩期最高流速与甲状腺单侧叶体积做直线相关分析,结果显示两者均为正相关,相关系数分别为:0.62、0.71。

结论:
1甲状腺功能减退症患者(病程<3个月)甲状腺内部回声为光点增粗伴局限性或弥漫性回声减低,亚临床甲减患者甲状腺内回声弥漫性减低者以无高回声光带为主,临床甲减患者以弥漫性回声减低伴高回声光带形成者居多。因此甲状腺内回声特征可以作为甲状腺功能减退症诊断的一项参考指标。
2甲状腺功能减退症患者(病程<3个月)甲状腺各径线及体积增大,临床甲减增大更明显,上述指标可反映甲状腺功能状态,可对病情发展及治疗效果进行评估。
3甲状腺功能减退症患者(病程<3个月)甲状腺组织内也可出现血流信号增多的“火海征”现象,甲状腺上动脉管径增宽,流速增高,但亚临床甲减与临床甲减两组间无显著性差异,故甲状腺组织内血流特征尚不能反映甲状腺功能减退的程度。
4甲状腺功能减退症患者(病程<3个月)甲状腺上动脉收缩期最高流速与甲状腺单侧叶体积呈正相关。
5甲状腺功能减退症患者(病程<3个月)甲状腺上动脉管径与促甲状腺激素水平呈正相关。

1.4 Spectral Doppler curves
The control group was low-speed low resistance Doppler spectrum shape type. The velocity in Subclinical hypothyroidism and clinical hypothyroidism group was higher than the control group,but also were low-impedance-type spectrum, spectrum peaks was blunt, diastolic flow decreased more slowly and evenly.
