| 摘要: |
| 目的 观察青光安Ⅱ号方有效组分对青光眼模型DBA/2J小鼠视网膜中RhoA、ROCK及Caspase-3蛋白表达的影响。方法 将8只（16只眼）雌性C57BL/6小鼠设为空白组（A组），48只（96只眼）雌性DBA/2J小鼠随机分成6组，每组8只（16只眼），分别为：模型组（B组）、益脉康分散片组（C组）、青光安Ⅱ号汤剂组（D组）、青光安Ⅱ号有效组分低浓度组（E组）、青光安Ⅱ号有效组分中浓度组（F组）、青光安Ⅱ号有效组分高浓度组(G组），B、C、D、E、F、G组DBA/2J小鼠喂养38周龄建立青光眼模型后开始干预，干预4周后Western blot法检测DBA/2J小鼠视网膜中RhoA、ROCK及Caspase-3蛋白的相对表达量。结果 干预4周后，与A组比较，B组RhoA、ROCK、Caspase-3蛋白相对表达量明显升高，差异均有统计学意义（P<0.05）；与B组比较，C、D、E、F、G组RhoA、ROCK、Caspase-3蛋白表达减少，差异均有统计学意义(P<0.05)；与C组比较，D、E、F组RhoA、ROCK、Caspase-3蛋白相对表达差异无统计学意义(P>0.05)；与C、D组比较，G组RhoA、ROCK、Caspase-3蛋白表达减少，差异有统计学意义(P<0.05)。结论 青光安Ⅱ号方有效组分能抑制Rho/ROCK信号通路及凋亡相关蛋白Caspase-3的表达，其中高浓度青光安Ⅱ号方有效组分效果优于益脉康分散片和青光安Ⅱ号方汤剂，推测青光安Ⅱ号方及其有效组分治疗青光眼的机制可能与其抑制Rho/ROCK信号通路及视网膜细胞凋亡相关蛋白表达有关。 |

| Abstract: |
| Objective To observe the effect of the effective component of Qingguang'an Ⅱ on the expression of RhoA, ROCK and Caspase-3 protein in the retina of DBA/2J mice with glaucoma. Methods Eight female C57BL/6 mice (16 eyes) were set as the blank group (Group A), and 48 female DBA/2J mice (96 eyes) were randomly divided into 6 groups, with 8 rats (16 eyes) in each group. Theses groups were model group (group B), Yimaikang Dispersible Tablet group (group C), Qingguang'an Ⅱ Decoction group (group D), Qingguang'an Ⅱ effective component low concentration group (Group E), Qingguang'an Ⅱ effective component middle concentration group (Group F), Qingguang'an Ⅱ effective component high concentration group (Group G). Groups B, C, D, E, F and G were fed for 38 weeks after birth, and the glaucoma model was established. From week 39, all the groups were treated for 4 weeks, and the expression of RhoA, ROCK and Caspase-3 protein was detected by western blot. Results After 4 weeks’ intervention, compared with group A, the expression of RhoA, ROCK, and Caspase-3 protein in group B was significantly increased, and the difference was statistically significant (P<0.05); Compared with group B, the expression of RhoA, ROCK, and Caspase-3 protein in group C, D, E, F, G were decreased, and the difference was statistically significant (P<0.05); Compared with groups C, the expression of RhoA, ROCK, Caspase-3 protein in group D, E and F was not statistically significant different (P>0.05). Compared with group C, D, the expression of RhoA, ROCK, and Caspase-3 protein in group G was decreased, and the difference was statistically significant (P<0.05). Conclusion The effective component of Qingguang'an Ⅱ can inhibit the expression of Rho/ROCK signaling pathway and apoptosis-related protein Caspase-3 in retinal cells, and the effect of high concentration Qingguang'an Ⅱ effective component is better than Yimaikang Dispersible Tablets and Qingguang'an Ⅱ Decoction The mechanism of Qingguang'an Ⅱ and its effective component for glaucoma may be related to its inhibition of Rho/ROCK signaling pathway and the expression of apoptosis-related proteins in retinal cells. |
