objective to analyze the ct appearance of thyroid carcinoma and the differential diagnosis of various thyroid disease.methods 83 cases of thyroid carcinoma and 119 cases of various benign disease with surgical and pathologically proved were analyzed retrospectively.results the ct findings of 83 cases of thyroid carcinoma include:ill defined nodules boundary (n=62),irregular necrosis(n=59),cystic(n=23),"peninsula" enhancing tubercles around the tumour(n=25),"mastoid" tubercles around the tumour(n=11),calcification(n=55) including large scale(n=27) and local(n=28),trachea invasion(n=15),neck or supraclavicular lymph node metastasis(n=27),the accurate of ct to differentia benignancy from malignancy on thyroid disease was 93.6%(189/202).conclusions "peninsula" enhancing tubercles was the characteristic sing of thyroid carcinoma,"mastoid" enhancing tubercles or large scale calcification was the affirmative sign,the ct signs was vary useful to differentiating thyroid disease.

摘 要］目的：分析甲状腺癌的ct表现及鉴别诊断要点。方法：回顾性分析经手术病理证实的83例甲状腺癌和119例甲状腺良性病变的ct表现，归纳总结不同病变的ct特征。结果：83例甲状腺癌中：边界不清62例，不规则坏死59例，囊性变23例，出现"半岛状"强化结节25例，"乳头状"强化结节11例，钙化55例(其中弥漫性钙化27例、局灶钙化28例)，侵犯气管15例，颈部或锁骨上淋巴结肿大27例，ct对甲状腺病变的良恶性鉴别诊断符合率93.6%(189/202)。结论："半岛状"强化结节是甲状腺癌的特征性表现，"乳头状"强化结节及弥漫性钙化可做为甲状腺癌的肯定性征象，掌握各种甲状腺病变的ct表现特点，对病变的定性诊断及鉴别诊断具有重要意义。

This conservation of a regulatory network supports the homology of metamorphosis in the chordate lineage.

因此，由甲状腺素诱导的变态过程受到了甲状腺素受体的调节，这种变态过程是所有脊索动物的祖先特征，这种调节网络的保守性也支持变态在脊索动物谱系中是具有同源性的。相关论文发表在《当代生物学》上。

However, the mechanism underlying the effect ofiodine excess on thyroid function remains unknown in part. Moreover, differentanimals show different ability to respond to iodine deficiency and iodine excess.Therefore, it is of great necessary to establish different animal models in vitro andtake a thorough evaluation of the impact of iodine intakes on thyroid function and itspossible regulation mechanism.

迄今的研究多集中于碘摄入水平与甲功关系这一现象的观察，对碘与甲状腺功能变化的剂量-效应关系及其具体调控机制的实验论证尚有待于进一步深入，且不同动物对碘缺乏与碘过量的反应性和耐受性有所不同，因此有必要建立不同的动物模型，就碘对甲状腺功能的影响及其可能的调控机制做系统而深入的研究。

Methods 548 cases of nodular goiter, 35 cases of thyroid adenoma and 17 cases of thyroid carcinoma were collected.

收集 5 4 8例结节性甲状腺肿，35例甲状腺腺瘤，17例甲状腺癌，观察其伴淋巴细胞性甲状腺炎的发生率及病变特点。

For hyperthyroid group, there are significant correlations between elements measured and between thyroid hormones, but not between elements and thyroid hormones.

在甲亢组，元素间存在显著性的相关，甲状腺激素水平间也有显著性的相关，而元素和甲状腺激素间未见显著性相关。

Aim: To investigate the characteristics of CT image about nodular struma and thyroid carcinoma, so as to improve the diagnostic accuracy about thyroid nodules.

目的：探讨结节性甲状腺肿与甲状腺癌的CT影像特点，旨在提高对甲状腺结节的诊断准确率。

Objective To investigate the incidence of sporadic type of painless thyroiditis and to analyse its laboratory characteristics.

目的 探讨甲状腺功能亢进症中的散发型无痛性甲状腺炎的发病率及实验室检查特征。

This is subacute granulomatous thyroiditis ( DeQuervain's disease), which probably follows a viral infection and leads to a painful enlarged thyroid.

这是亚急性甲状腺炎的病例，该患者可能伴有病毒感染和有痛性甲状腺肿大。

Results: In 32 cases of thyroid neoplasm, there were 22 cases with uneven density, 19 cases with unclear border, 15 cases with irregular necrosis and 12 cases with cystisc degeneration. CT scan showed that the cases of invasion of trachea, esophagus, carotid sheath and swollen lymph nodes of neck and supraclavicle were 14, 6, 5 and 8 respectively.

结果：32例甲状腺肿瘤的主要CT表现为密度不均22例，边界不清19例，不规则坏死15例，囊性变12例，CT判断甲状腺肿瘤侵犯气管、食管、颈动脉鞘和颈部或锁骨上淋巴结肿大转移分别为：14例、6例、5例和8例。

Therefore, TH-regulated metamorphosis, mediated by TR, is an ancestral feature of all chordates.

因此，由甲状腺素诱导的变态过程受到了甲状腺素受体的调节，这种变态过程是所有脊索动物的祖先特征，这种调节网络的保守性也支持变态在脊索动物谱系中是具有同源性的。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
