概括
血清神经纤维光链 (sNfL) 水平可以帮助区分非动脉炎前部缺血性视觉神经病变 (NAION) 和视觉神经炎 (ON) 在水素-4 (AQP4) -IgG阳性神经omyelitis光谱障碍 (NMOSD) 和髓寡聚细胞糖蛋白抗体相关疾病 (MOGAD). 较高的sNfL水平与较差的视觉结果相关.
科学领域:
- 眼科医生 眼科 眼科
- 神经学 神经学
- 生物标志物研究 生物标志物研究
背景情况:
- 血清神经丝光链 (sNfL) 是神经轴损伤的潜在生物标志物.
- 从临床上来说,区分非动脉炎前部缺血性视觉神经病变 (NAION) 和视觉神经炎 (ON) 是非常重要的.
- ON可能与自身免疫性疾病有关,如水素-4 (AQP4) -IgG阳性神经omyelitis光学谱障碍 (NMOSD) 和髓寡基细胞蛋白抗体相关疾病 (MOGAD).
研究的目的:
- 评估sNfL在区分NAION与AQP4-IgG+NMOSD和MOGAD相关的ON方面的歧视能力.
- 评估急性发作期间的sNfL水平与随后的视觉结果之间的相关性.
主要方法:
- 在患有急性视神经病变 (NAION,AQP4-IgG+NMOSD ON,MOGAD ON) 和健康对照患者中测量了sNfL水平.
- 进行了统计分析,以比较不同组的sNfL水平,并评估与视力敏度的相关性.
主要成果:
- 在所有患者队列和对照组之间观察到sNfL水平的显著差异 (p < 0.001).
- 与ON相比,NAION中的sNfL水平显著更高 (p < 0.001).
- 对于sNfL的60 pg/mL值显示在区分NAION和ON时具有很高的特异性 (100%) (AUC=0.82).
- 与最终视力敏度相关的sNfL水平,独立于视神经病变的病因 (R2 = 0.49,p < 0.001).
结论:
- sNfL水平显示出作为生物标志物的潜力,可以区分NAION与AQP4-IgG+NMOSD和MOGAD相关的ON.
- 在患有视神经病变的患者中,sNfL水平可以作为长期视觉预后的预测指标.
- 建议使用标准化的z-score进行进一步的研究,以获得可靠的临床解释.

Local Anesthetics: Differential Sensitivity of Nerve Fibers
1.4K
Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...

Types of Intermediate Filaments
4.7K
The intermediate filaments are an essential component of the cytoskeleton. Presently six types of intermediate filament have been identified. Type I and II are acidic and basic keratin proteins. Type III is of mesodermal origin and comprises four proteins: vimentin, desmin, glial fibrillary acidic protein (GFAP), and peripherin. Vimentin is commonly found in mesenchymal cells, desmin in muscle cells, GFAP in astrocytes, while peripherin is found in peripheral nervous system neurons (PNS). Type...
