- * 生物化学 * 生物化学
- * 免疫学 免疫学
背景情况:
- *严重喘 (SA) 是一种异质的呼吸道炎症疾病,需要新的诊断生物标志物.
- * 微RNAs (miRNAs) 是基因表达的关键转录后调节者.
- *外体保护miRNAs,促进细胞间通信和生物流体中的稳定性.
研究的目的:
- * 调查严重喘患者的细胞内和外体miRNA概况.
- *评估miRNAs作为喘非侵入性生物标志物的潜力.
- * 阐明特定miRNAs在SA.病变发生过程中的作用.
主要方法:
- * 量化逆转录聚合酶链反应 (qRT-PCR) 用于检测miRNA水平.
- *对喘患者和健康对照患者的血清和血清衍生的外体进行了分析.
- *特定的miRNAs (miR-21,miR-223,let-7a) 的量化.
主要成果:
- *与对照组相比,喘患者的miR-21和let-7a细胞内含量升高 (miR-223没有显著差异).
- *在严重喘中,miR-21水平特别高,而在轻度至中度喘中,let-7a水平增加.
- *所有分析的miRNA在严重喘患者的外体中都显著高.
结论:
- * 细胞内和外体miRNAs的独特模式与严重的喘有关.
- *这些miRNAs显示出作为喘敏感和特定的非侵入性生物标志物的承诺.
- *需要在更大的队列中进一步验证,以确认这些发现及其临床实用性.

Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
