摘要:

探究黄连解毒汤(Huanglian Jiedu Decoction,HJD)对血管性痴呆(vascular dementia,VD)大鼠神经元细胞凋亡和细胞焦亡的影响及作用机制。将70只大鼠随机选取10只作为假手术组,其余大鼠以改良双侧颈总动脉阻断法制备VD大鼠模型,将造模成功的大鼠随机分为模型组、HJD低剂量组(1.5 g/kg)、HJD中剂量组(3.0 g/kg)、HJD高剂量组(6.0 g/kg)、HJD高剂量(6.0 g/kg)+JNK激活剂anisomycin组(5 mg/kg),每组10只。开展水迷宫实验进行学习记忆检测;观察海马组织病理学变化及细胞凋亡情况;ELISA检测大鼠海马组织炎症因子含量;利用Western blot和RT-qPCR等方法检测c-Jun氨基末端激酶(c-Jun N-terminal kinase,JNK)、磷酸化的JNK(p-JNK)、叉头盒蛋白1(forkhead box protein O1,FOXO1)、磷酸化FOXO1(p-FOXO1)、Nod样受体蛋白3(NOD-like receptor protein 3,NLRP3)、含CARD结构域的凋亡相关斑点样蛋白(apoptosis-associated speck-like protein containing a CARD,ASC)、半胱氨酸天冬氨酸特异蛋白酶(cysteinyl aspartate specific proteinase-1,Caspase-1)、N端-消皮素D(gasdermin D-N,GSDMD-N)、Caspase-3、Caspase-9、B细胞淋巴瘤-2(B-cell lymphoma/leukemia-2,BCL-2)、BCL-2相关X蛋白(BCL-2-associated-X-protein,BAX)表达水平。与模型组比较,HJD干预后可明显提高模型大鼠的学习、空间记忆能力(P<0.05或P<0.01);减轻海马组织的病理形态学损伤;神经元细胞凋亡数量明显减少(P<0.05或P<0.01);海马组织白细胞介素1β(interleukin-1β,IL-1β)、IL-18、肿瘤坏死因子α(tumor necrosis factor-α,TNF-α)含量明显降低(P<0.05或P<0.01);下调JNK、FOXO1、NLRP3、ASC、Caspase-1、GSDMD-N、Caspase-3、Caspase-9、BAX蛋白及mRNA的表达(P<0.05或P<0.01),上调BCL-2蛋白及mRNA的表达(P<0.05或P<0.01)。然而,anisomycin的使用可部分逆转HJD对于细胞凋亡和细胞焦亡的治疗效果。以上结果表明,HJD通过抑制JNK/FOXO1信号通路,有效减轻VD大鼠的细胞凋亡和细胞焦亡,从而改善VD大鼠的学习记忆能力。

Abstract:

This study aims to investigate the effect and mechanism of Huanglian Jiedu Decoction (HJD) on neuronal apoptosis and pyroptosis in rats with vascular dementia (VD). Ten rats were randomly selected from 70 rats as the sham group, while the remaining rats were subjected to modified bilateral common carotid artery occlusion to establish vascular dementia VD rat models,and the rats were randomly divided into model group, low-dose HJD group (1.5 g/kg), medium-dose HJD group (3.0 g/kg), high-dose HJD group (6.0 g/kg), high-dose HJD (6.0 g/kg) and JNK activator anisomycin group (5 mg/kg), with ten rats in each group. The water maze test was used to detect learning and memory, the pathological changes and apoptosis of hippocampus were observed, and the content of inflammatory factors in hippocampus was detected by ELISA. The expression of C-Jun N-terminal kinase (JNK), phosphorylated JNK (p-JNK), forkhead box protein O1(FOXO1), phosphorylated FOXO1 (p-FOXO1), NOD-like receptor protein 3 (NLRP3), apoptosis-associated speck-like protein containing a CARD (ASC), cysteinyl aspartate specific proteinase-1 (Caspase-1), gasdermin D-N (GSDMD-N), Caspase-3, Caspase-9, B-cell lymphoma/leukemia-2 (BCL-2), BCL-2-associated-X-protein (BAX) was detected by Western blot and RT-qPCR. Compared with Mod group,the intervention of HJD improved the learning and spatial memory abilities of model rats significantly(P<0.05 or P<0.01), alleviated pathological morphology damage in hippocampal tissue, and reduced the number of neuronal apoptosis significantly(P<0.05 or P<0.01). The content of interleukin-1β (IL-1β), IL-18 and tumor necrosis factor-α (TNF-α) in hippocampus decreased significantly (P<0.05 or P<0.01), down-regulated the expression of JNK, FOXO1, NLRP3, ASC, Caspase-1, GSDMD-N, Caspase-3, Caspase-9, BAX proteins and mRNA (P<0.05 or P<0.01), and up-regulated the expression of BCL-2 protein and mRNA simultaneously (P<0.05 or P<0.01). However, the use of anisomycin partially reversed the therapeutic effect of HJD on apoptosis and pyroptosis. These results suggest that HJD effectively alleviated apoptosis and pyroptosis in VD rats by inhibited the JNK/FOXO1 signaling pathway, thereby improved the learning and memory ability of VD rats.
