摘要:

目的 观察平痫冲剂及其拆方的抗痫作用,并探讨其作用机制。 方法 将270只4周龄Wistar大鼠随机分为空白对照组36只,造模组234只,采用戊四唑腹腔注射制备癫痫模型。癫痫模型大鼠制备成功216只,随机分为模型对照组、阳性对照组、化痰组、祛瘀组、息风组、平痫组,每组各36只,阳性对照组给予丙戊酸钠0.36 g/kg,化痰组、祛瘀组、息风组用药均来自平痫冲剂拆方,化痰组给予化痰药(石菖蒲、胆南星组成)1.40 g/kg灌胃,祛瘀组给予祛瘀药(丹参、郁金组成)2.08 g/kg灌胃,息风组给予息风药(僵蚕、天麻、代赭石、白芍组成)2.96 g/kg灌胃,平痫组给予平痫药(上述化痰、祛瘀、息风药物组成)3.22 g/kg灌胃,空白对照组和模型对照组给予等量生理盐水灌胃,各组均灌胃治疗21 d。 结果 与模型对照组比较,平痫组及各拆方组在药物干预24 h、48 h、72 h、7 d、14 d、21 d后,B淋巴细胞瘤因子相关X蛋白(Bax)阳性表达减弱,差异有统计学意义(P<0.05);与模型对照组比较,平痫组及各拆方组在药物干预48 h、72 h、7 d、14 d、21 d后B淋巴细胞瘤-2基因(Bcl-2)蛋白阳性表达增强,差异有统计学意义(P<0.05)。与模型对照组比较,阳性对照组、化痰组、息风组、平痫组,锥体神经元数目及形态出现不同程度修复,其中平痫组改善程度优于其余拆方组,祛瘀组未见明显变化。 结论 平痫冲剂及其拆方可能通过抑制神经元凋亡,下调Bax蛋白的表达,上调Bcl-2蛋白的表达,进而发挥抗痫作用。

Abstract:

Objective To observe the anti-epileptic effects of Pingxian granules and its split formula, and explore their anti-epileptic mechanisms. Methods Totally 270 4-week-old Wistar rats were randomly divided into a blank control group of 36 rats and a model group of 234 rats. The epilepsy model was prepared by intraperitoneal injection of pentylenetetrazole. After the successful preparation of epilepsy model rats(n=216), they were randomly divided into a model control group, a positive control group, a phlegm-resolving group, a blood stasis-removing group, wind-stopping group, and a Pingxian group, with 36 rats in each group. The positive control group was given 0.36 g/kg of sodium valproate (VPA), while the phlegm-resolving group, blood stasis-removing group, and wind-stopping group were all given medications from the split formula of Pingxian granules. The phlegm-resolving group was given 1.40 g/kg of phlegm-resolving drugs (Acorus tatarinowii and Dannanxing) by gavage; the blood stasis-removing group was given 2.08 g/kg of phlegm-resolving drugs (Danshen and Yujin) by gavage; the wind-stopping group was given 2.96 g/kg of wind-stopping drugs (Bombyx mori, Tianma, Daizheshi and Baishao) by gavage; the Pingxian group was given 3.22 g/kg of anti-epileptic drugs (composed of the aforementioned phlegm-resolving drugs, blood stasis-removing drugs, and wind-stopping drugs) by gavage. The blank control group and model control group were given an equal amount of physiological saline by gavage. Each group was treated by gavage for 21 days. Results Compared with the model control group, the Pingxian group and each group with split formula showed reduced positive expression of Bax protein at 24 h, 48 h, 72 h, 7 d, 14 d, and 21 d after drug intervention(P<0.05). Compared with the model control group, the Pingxian group and each group with split formula showed enhanced positive expression of Bcl-2 protein at 48 h, 72 h, 7 d, 14 d, and 21 d after drug intervention(P<0.05). Compared with the model control group, the positive control group, phlegm-resolving group, blood stasis-removing group, wind-stopping group and Pingxian group showed varying degrees of repair in the number and morphology of pyramidal neurons, with the Pingxian group showing greater improvement than the other groups with split formula, while the blood stasis-removing group showed no significant changes. Conclusion Pingxian granules and its split formula may exert anti-epileptic effects by inhibiting neuronal apoptosis, downregulating Bax protein expression, and upregulating Bcl-2 protein expression.
