概括
这项研究确定了深成年人碳水化合物抗原72-4 (CA72-4) 的参考间隔,发现上限为8.5U/mL. 这一新的极限有助于减少健康查中的错误阳性.
科学领域:
- 临床化学 临床化学
- 瘤标志物分析分析
- 参考区间的建立 参考区间的建立
背景情况:
- 确定精确的参考间隔 (RIs) 对于瘤标记物,如碳水化合物抗原72-4 (CA72-4) 对于有效的癌症查至关重要.
- 现有的RI可能无法普遍适用,需要进行特定区域的研究.
研究的目的:
- 在中国深的健康成年人中建立血清CA72-4的参考间隔.
- 为了验证已建立的RI在临床使用中的适用性.
主要方法:
- 根据CLSI EP28-A3c指南,对2614名健康成年人的血清CA72-4水平进行了分析.
- 异常值被删除,并进行了正常性测试. 使用2.5和97.5百分位数非参数推导RI.
- 对206名成年人的独立队列进行了验证,以评估超标率.
主要成果:
- CA72-4值表现出一个右倾分布. 由于没有发现与性别或年龄相关的显著差异,因此采用了联合RI.
- 确定的RI为0.54-8.5U/mL (90%CI的上限为8.29-8.90U/mL). 确定的RI为0.54-8.5U/mL (90%CI的上限为8.29-8.90U/mL).
- 验证显示,超标率为4.85%,符合可接受的标准 (<5%).
结论:
- 该研究确定了深成年人CA72-4的区域特定RI,上限为8.5U/mL,高于制造商的价值.
- 这种较高的极限可能会降低健康查中的错误阳性,尽管由于随年龄的轻微增加,建议对老年人进行谨慎的解释.
- 这些发现为深和类似人群的CA72-4测试提供了宝贵的参考.

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution
382
Drug distribution in the human body is influenced by several factors, including plasma protein concentration, body composition, blood flow, tissue-protein concentration, and tissue fluid pH. Among these, changes in plasma protein concentration and body composition due to aging significantly affect how drugs are distributed within the body. Specifically, aging is associated with a decrease in albumin levels by about 10% and an increase in α1-acid glycoprotein levels. These alterations are...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT
973
Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...
