- 免疫学 免疫学 免疫学
- 放射学 放射学是一门学科.
背景情况:
- 慢性腹膜下血瘤 (CSDH) 发病因传统上与炎症有关,但抗炎疗法显示有效性有限.
- 新兴研究表明,免疫失调,而不是仅仅是炎症,对于CSDH发育至关重要.
研究的目的:
- 在CSDH进化中研究巨细胞极化动态.
- 为了将免疫状态与CSDH亚型和手术复发相关联.
主要方法:
- 使用纳卡古奇CT分类对CSDH进行分类 (均,层状,分离,状).
- 通过流细胞计和ELISA分析了巨分极 (M1/M2百分比) 和细胞因子 (IL-1β,IL-6,IL-12,TNF-α,IL-4,IL-10,IL-13,TGF-β) 的概况.
- 通过逻辑回归评估CT亚型,巨分极和复发之间的关系,并开发了一个名ogram预测模型.
主要成果:
- CSDH进化显示M1巨细胞减少,M2巨细胞增加,M1/M2比率下降.
- 复发性CSDH病例呈现出较高的M1/M2比率和M1百分比,但与非复发性病例相比,M2百分比较低.
- 纳入CT分类,大脑缩和血瘤体积的诺莫грам显示出强大的复发预测效率 (AUC 0.898).
结论:

Chronic Inflammation: Introduction
Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...
Bacterial Meningitis II: Pathophysiology
Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...
