概括
测量血清素 (CTN) 有助于早期诊断甲状腺髓癌 (MTC) 和C细胞增生 (CCH). 然而,试验变异性和影响因素需要仔细解释CTN水平.
科学领域:
- 内分泌学 在内分泌学.
- 在瘤学瘤学.
- 生物化学 生物化学
背景情况:
- 素 (CTN) 是甲状腺C细胞产生的32氨基酸多激素,对于通过血液测量评估C细胞活性至关重要.
- 血清CTN的免疫测试方法受到分析,生理,药理和病理因素的影响,导致对诊断甲状腺髓癌 (MTC) 和C细胞增生 (CCH) 的测试依赖的切断差异性.
研究的目的:
- 评估血清色素 (CTN) 度在识别骨髓甲状腺癌 (MTC) 和C细胞增生 (CCH) 的诊断效用.
- 将CTN与PCT的诊断性能进行比较,并讨论MTC当前诊断方法的局限性.
主要方法:
- 使用免疫检测方法测量基础血清酸 (CTN) 度.
- 将CTN诊断能力与PCT进行比较,并讨论影响CTN值的因素.
主要成果:
- 基底CTN水平>60-100 pg/mL强烈暗示MTC;截止值和60 pg/mL之间的水平可能表明MTC或CCH.
- 虽然PCT显示了MTC的可比诊断能力,但在亚临床感染中可能会出现PCT值升高 (>50 pg/mL),冒着过度诊断的风险.
- 刺激的CTN测试可以提高MTC诊断,但不一致的切断值有利于目前使用基底CTN测量.
结论:
- 在患有甲状腺结节的患者中,血清CTN测量可以促进较早的MTC或CCH诊断,而不是仅用成像或细胞学.
- 尽管存在差异,但基底血清CTN仍然是MTC诊断的宝贵工具,特定的度范围表明MTC或CCH的可能性更高.
- 可以考虑使用前素 (PCT),但其在非瘤条件下潜在的错误阳性需要谨慎,强调CTN评估的持续重要性.

Synthesis and Functions of Calcitonin
1.5K
Calcitonin, a vital polypeptide hormone, regulates calcium levels within body fluids. It is released by the parafollicular cells, also known as C cells, situated in the follicular epithelium of the thyroid gland. Calcitonin responds to fluctuations in blood calcium levels and the influence of gastrointestinal hormones like gastrin and cholecystokinin.
The exact mechanisms by which calcitonin operates in calcium homeostasis remain elusive, but its significance is evident in several vital...

Synthesis and Regulation of Thyroid Hormones
4.1K
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...

Blood Studies for Cardiovascular System I: Cardiac Biomarkers
76
Cardiac biomarkers are enzymes, proteins, and hormones released into the blood when cardiac cells are injured. They are powerful tools for triaging.
The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...
