摘要: 目的  研究应用葛根素对大鼠视神经夹伤模型视网膜神经节细胞保护作用的机制。设计 实验研究。研究对象 SD大鼠54只。方法 大鼠随机分为三组(每组18只)。治疗组大鼠于视神经夹伤后2小时及之后每天使用葛根素(10 mg/ml)日2次滴眼。对照组大鼠于视神经夹伤后2小时及之后每天使用无菌生理盐水日2次滴眼。空白组大鼠不手术。于15天后处死大鼠,分别进行视网膜细胞凋亡、转录组学和代谢组学检测。主要指标 视网膜TUNEL染色阳性细胞数量,转录组学和代谢组学数据分析。结果 对照组视网膜凋亡细胞数量较空白组增多,而治疗组视网膜凋亡细胞数量较于对照组减少(P<0.01)。葛根素通过AGE-RAGE通路和细胞骨架通路调节了Col6a2、Col1a2、Vcan和Fbln1基因的表达(P均<0.05),并参与调节视网膜丙氨酸、天冬氨酸、谷氨酸和精氨酸等物质的代谢(P均<0.05)。结论 葛根素滴眼有可能减少大鼠视神经夹伤模型视网膜神经节细胞凋亡。葛根素可能调节视神经夹伤后大鼠视网膜Col6a2、Col1a2、Vcan和Fbln1基因的表达及丙氨酸、天冬氨酸、谷氨酸和精氨酸代谢,并可能因此对大鼠视神经夹伤后视网膜神经节细胞凋亡产生保护作用。

Abstract:  Objective To study the mechanism of neuroprotective action of puerarin on retinal ganglion cells in a rat model of optic nerve clipping injury. Design Experimental study. Participants 54 SD rats. Method SD rats were randomly divided into three groups ( each group n=18). The treatment group (optical nerve crush+puerarin, ONC+PUE) received puerarin eye drops (10mg/ml) twice a day, since 2 hours after optic nerve clipping injury. The control group rats were treated with sterile physiological saline eye drops twice a day, since 2 hours after optic nerve clipping injury. Blank group rats were not injury operated on. Rats were euthanized 15 days later and subjected to retinal cell apoptosis, transcriptome, and metabolome analysis. Main Outcome Measures The number of TUNEL positive cells in retina, transcriptome and metabolome data analysis. Results The number of apoptotic cells of retina in the control group increased compared to the blank group, while the number of apoptotic cells in the treatment group decreased compared to the control group (P<0.01). Puerarin regulates the expression of Col6a2, Col1a2, Vcan, and Fbln1 genes through the AGE-RAGE pathway and cytoskeleton pathway (all P<0.05), and participates in regulating the metabolism of substances such as alanine, aspartate, glutamate, and arginine in retina (all P<0.05). Conclusion Puerarin treatment may reduce apoptosis of optic ganglion cells in a rat model of optic nerve clipping injury. Puerarin can regulate the expression of Col6a2, Col1a2, Vcan, and Fbln1 genes, as well as the metabolism of alanine, aspartate, glutamate, and arginine in the retina of rats after optic nerve clipping injury, and may therefore have a neuroprotective effect on the damage and apoptosis of the retinal ganglion cells in rats after optic nerve clipping injury.
