概括
抗VEGF静脉注射 (IVI) 减少了视网膜血管瘤的血管性和大小. 这种治疗使病变变白,并减少其红色成分,有助于进一步的干预.
科学领域:
- 眼科医生 眼科 眼科
- 医疗成像医学成像
- 在瘤学瘤学.
背景情况:
- 视网膜血管瘤,包括血管瘤和血管扩散性瘤 (VPT),对视力构成重大威胁.
- 抗VEGF治疗越来越多地用于各种眼血管疾病.
研究的目的:
- 量化评估抗VEGF内注射 (IVI) 对视网膜血管瘤的血管性和大小的影响.
- 用RGB分析分析IVI后的颜色底图像的变化.
主要方法:
- 分析了来自8名患者的10例视网膜血管瘤 (6例VHL相关的血管瘤,4例VPT) 的色底图像.
- ImageJ软件用于RGB分析,以计算白色强度和红色指数.
- 损伤盘面积比率被测量以评估损伤大小的变化.
主要成果:
- 总的来说,IVI显著增加了白色强度 (1.34到1.5,P=0.001) 和降低了红色指数 (1.14到0.85,P<0.001).
- 在IVI后,VHL和VPT组都显示出白色强度增加和红色指数下降.
- 在两组中都观察到损伤-盘面积比率的显著减少,表明尺寸减少.
结论:
- 抗VEGF IVI有效地减少了视网膜血管瘤的血管性,通过增加病变变白和减少红色成分来证明这一点.
- 观察到的变化表明,抗VEGF疗法减少了血管瘤的血管性和大小,可能为随后的治疗做好准备.

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

Blood vessel formation starts early during embryonic development, around day 7. In the extraembryonic yolk sac, mesodermal precursor cells called hemangioblast proliferate and differentiate into angioblast. Angioblasts express vascular endothelial growth factor receptor 2 or VEGFR2, which binds VEGF-A, a proangiogenic factor, guiding blood vessel formation. VEGF signaling promotes angioblasts to form a blood island in the developing embryo. Angioblasts further differentiate, giving rise to...
