摘要

目的探讨滋阴明目丸对视网膜色素上皮（RPE）细胞光损伤后的保护作用及可能机制。方法60只SD大鼠分为滋阴明目丸低、中、高剂量组和空白组

每组15只。滋阴明目丸各剂量组分别予以滋阴明目丸浓度为0. 39、0. 78、1. 56 g/ml的混悬液灌胃

灌胃量均为34 ml/（kg·d）

空白组予以生理盐水34 ml/（kg·d）灌胃

各组均给药7天。灌胃结束后制备含药血清

并采用MTT法筛选后续实验的含药血清浓度。实验分为空白组（不加含药血清）、血清组（加含药血清）、模型组（光损伤造模、不加含药血清）及中药组（光损伤造模、加含药血清）。培养24 h后模型组和中药组建立体外RPE细胞光损伤模型。检测各组细胞凋亡率

测定半胱氨酸蛋白酶1 （Caspase-1）、半胱氨酸蛋白酶3 （Caspase-3）蛋白及mRNA表达。结果中剂量血清为最佳给药剂量并用于后续实验。与空白组比较

血清组细胞凋亡率、Caspase-1和Caspase-3蛋白及mRNA表达差异均无统计学意义（P> 0. 05）

模型组细胞凋亡率、Caspase-1和Caspase-3蛋白及mRNA表达显著上升（P <0. 05）;与模型组比较

中药组细胞凋亡率、Caspase-1和Caspase-3蛋白及mRNA表达显著下降（P <0. 05）。结论滋阴明目丸含药血清能有效抑制RPE细胞光损伤后的细胞凋亡

可能与抑制细胞凋亡因子Caspase-1、Caspase-3蛋白及mRNA表达有关。

Abstract

Objective To observe the effects and possible mechanism of Ziyin Mingmu Pills（滋阴明目丸） on retinal pigment epithelial（RPE） cells after light injury. Methods A total of 60 SD rats were divided into Ziyin Mingmu Pills low

medium and high dose groups and a blank group

with 15 rats in each group. The groups of different Ziyin Mingmu Pills dosages were respectively administered with the suspension of Ziyin Mingmu Pills at a concentration of 0. 39

0. 78

and 1. 56 g/ml. The gavage volume was 34 ml/（kg · d）

and the blank group was given34 ml/（kg·d） of normal saline for gavage

each group was administered for 7 days. The drug-containing serum was prepared in the end of the gavage

and the concentration of the drug-containing serum in the subsequent experiment was screened by the MTT method. The selected cells for experiment were divided into a blank group（without drugcontaining serum）

serum group（with drug-containing serum）

model group（light damage modeling

no drug-containing serum）

and Chinese medicine group（light damage modeling with drug-containing serum）. After 24 hours of culture

the in vitro RPE cell light damage models of model group and the Chinese medicine group were established.The apoptosis rate of each group was measured

and the expression of caspase-1

caspase-3 and mRNA were measured. Results The medium dose serum was the optimal dose

and it was used in subsequent experiments. Compared with the blank group

the apoptosis rate

expression of Caspase-1 and Caspase-3 protein and mRNA in serum group were not statistically significant（P > 0. 05）. The apoptosis rate

Caspase-1 and Caspase-3 protein and mRNA expression in the model group increased significantly（P < 0. 05）. Compared with the model group

the apoptosis rate

Caspase-1 and Caspase-3 protein and mRNA expression in the Chinese medicine group were significantly decreased（P < 0. 05）. Conclusion Ziyin Mingmu Pills can effectively inhibit the apoptosis of RPE cells after light injury. The mechanism may be related to the inhibition of the expression of Caspase-1

Caspase-3 protein and its mRNA.
