通过调节补体通路和C5a/ C5aR1轴来减少急性喉炎的炎症. 这种传统的中医药可以抑制炎症媒介和免疫细胞的激活,
科学领域:
- 药理学
- 免疫学
- 传统中国医学
背景情况:
- 急性喉炎 (AP) 是一种常见的感染,导致喉疼痛和吞困难.
- 通过清除热量和减少胀,用于治疗AP.
- 在治疗AP时YYJH的精确分子机制仍然不充分理解.
研究的目的:
- 阐明YYJH在治疗急性炎中的抗炎机制.
- 确定主要的活性成分及其生物点.
- 使用体内和体外模型验证治疗效果.
主要方法:
- 使用血清药理学和UPLC-Q-Exactive-Orbitrap-MS来确定YYJH的成分.
- 在氨诱导的AP大鼠模型和LPS刺激的NP69SV40T细胞中评估了抗炎活性.
- 转录组学,蛋白质组学和生物信息学分析揭示了基础机制,通过分子生物学实验验证.
主要成果:
- 已确定YYJH的12个血液输入成分具有验证的抗炎作用.
- 在AP大鼠中,YYJH治疗改善了喉粘膜病理,减少了炎症细胞,降低了血清炎症因子.
- 在机制上,YYJH降低了经典补充路径 (C1q,C3,C5,C9) 和C5a/C5aR1轴,抑制了巨细胞的透和促炎细胞因子的释放.
结论:
- 通过调节经典补体通路和C5a/C5aR1轴,YYJH具有抗炎作用.
- 该药物抑制炎症媒介的产生和免疫细胞的激活,为治疗急性炎提供了分子基础.
- 这项研究为YYJH在AP管理中的传统使用提供了科学验证.

Acute Pharyngitis
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:
Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
