红花黄色素注射液联合抗VEGF药物治疗非缺血性视网膜中央静脉阻塞

目的:分析红花黄色素注射液联合抗血管内皮生长因子(VEGF)药物治疗非缺血性视网膜中央静脉阻塞(CRVO)的疗效和安全性。方法:选取2017-04/2021-12于南昌大学附属眼科医院接受治疗的非缺血性CRVO合并黄斑水肿患者91例91眼,随机分为观察组(47例47眼,采用红花黄色素注射液联合玻璃体腔注射雷珠单抗治疗)和对照组(44例44眼,采用玻璃体腔注射雷珠单抗治疗)。随访11mo,观察两组患者最佳矫正视力(BCVA)和中心凹视网膜厚度(CRT)改善情况,并记录视网膜出血完全吸收、抗VEGF药物注射次数、缺血性CRVO发生情况及全身和眼部并发症发生情况。结果:治疗后1、2、3、5、7、9、11mo,两组患者BCVA和CRT均较治疗前显著改善,且治疗后3、5、7、9、11mo,观察组患者BCVA和CRT均优于对照组(均P<0.05)。治疗后5、7、9、11mo时,观察组患者视网膜出血完全吸收率均高于对照组(P<0.05)。随访期间,观察组患者抗VEGF药物注射次数明显少于对照组(4.83±1.05次vs 5.75±1.01次,P<0.05),缺血性CRVO发生率明显低于对照组(21%vs 86%,P<0.05),且两组患者均未出现与治疗相关的全身和眼部并发症。结论:红花黄色素注射液联合抗VEGF药物是治疗非缺血性CRVO安全有效的方法,可显著改善视力,降低CRT,该治疗方案与抗VEGF药物单药治疗相比可增加视网膜出血完全吸收率、减少抗VEGF药物注射次数、减少缺血性CRVO发生率。

Altered brain network centrality in patients with retinal vein occlusion: a resting-state fMRI study

AIM:To explore the intrinsic brain activity variations in retinal vein occlusion(RVO)subjects by using the voxel-wise degree centrality(DC)technique.METHODS:Twenty-one subjects with RVO and twentyone healthy controls(HCs)were enlisted and underwent the resting-state functional magnetic resonance imaging(rs-f MRI)examination.The spontaneous cerebrum activity variations were inspected using the DC technology.The receiver operating characteristic(ROC)curve was implemented to distinguish the DC values of RVOs from HCs.The relationships between DC signal of definite regions of interest and the clinical characteristics in RVO group were evaluated by Pearson’s correlation analysis.RESULTS:RVOs showed notably higher DC signals in right superior parietal lobule,middle frontal gyrus and left precuneus,but decreased DC signals in left middle temporal gyrus and bilateral anterior cingulated(BAC)when comparing with HCs.The mean DC value of RVOs in the BAC were negatively correlated with the anxiety and depression scale.CONCLUSION:RVO is associated aberrant intrinsic brain activity patterns in several brain areas including painrelated as well as visual-related regions,which might assist to reveal the latent neural mechanisms.
