研究目的: |
1、在早产儿视网膜病变人群中鉴定血浆可溶性CD93是否可作为血液标志物,确定血浆浓度阈值标准; 2、进行CD93基因多态性检测,观察CD93基因多态性与早产儿视网膜病变的关系; 3、在氧诱导视网膜病变模型中观察CD93及MMRN-2的表达情况及与视网膜血管共定位情况,观察CD93敲除后C57小鼠是否可形成氧诱导视网膜病变模型进一步鉴定CD93在该模型中的作用机制; 4、采用慢病毒载体玻璃体腔注射敲低CD93及CD93及MMRN2阻断抗体4E1,观察氧诱导视网膜病变模型新生血管渗漏情况,并与抗VEGF药物玻璃体腔注射进行对比观察有效性; 5、在视网膜微血管内皮细胞中进行CD93表达及优势通路蛋白的验证。 |

Objectives of Study: |
1.Identify whether plasma soluble CD93 can serve as a blood marker in the population with retinopathy of prematurity, and determine the standard of plasma concentration threshold 2.Perform CD93 gene polymorphism detection to observe the relationship between CD93 gene polymorphism and retinopathy of prematurity 3.Observe the expression of CD93 and MMRN-2 and their co-localization with retinal blood vessels in the oxygen-induced retinopathy model, and observe whether CD93 knockout C57 mice can form an oxygen-induced retinopathy model to further identify the mechanism of CD93 in this model 4.Use lentiviral vector intravitreal injection to knock down CD93 and CD93 and MMRN2 blocking antibody 4E1, observe the neovascular leakage in the oxygen-induced retinopathy model, and compare the effectiveness with intravitreal injection of anti-VEGF drugs 5.Verify CD93 expression and dominant pathway proteins in retinal microvascular endothelial cells |
