背景情况:
- 状甲状腺癌 (PTC) 的宫淋巴结 (LN) 转移显著影响预后和复发.
- 细胞学评估本身在诊断LN参与方面存在局限性.
- 精细针吸收甲状腺蛋白 (FNA-Tg) 是一个潜在的生物标志物,但在特定的患者群体中,如那些具有甲状腺蛋白抗体 (TgAbs) 的患者,其最佳切断和实用性需要澄清.
研究的目的:
- 评估FNA-Tg在确定PTC患者宫LN转移的诊断性能.
- 在这种情况下,确定FNA-Tg的最佳切割值.
- 为了研究甲状腺蛋白抗体 (TgAbs) 对FNA-Tg诊断精度的影响.
主要方法:
- 从60名PTC患者中对63名LNs进行了回顾性分析.
- 同时进行细胞学评估和FNA-Tg测量.
- 计算诊断性能指标 (灵敏度,特异性,PPV,NPV,准确性) 并确定FNA-Tg切割值.
主要成果:
- 4.23 ng/mL的FNA-Tg切线显示了100%的灵敏度,90.2%的特异性和93.6%的整体准确性.

Synthesis and Regulation of Thyroid Hormones
4.3K
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...

The Thyroid Gland
3.7K
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...
