摘要:

目的:探讨潜阳育阴颗粒通过调节炎症因子修复血脑屏障(blood-brain barrierBBB)促进急性缺血性脑卒中(acute ischemic strokeAIS)神经功能恢复的作用机制。方法:采用SD雄性大鼠,通过大脑中动脉阻塞(tMCAO),阻塞时间90 min,建立AIS模型,分为假手术组、模型组、潜阳育阴颗粒低/高剂量组。治疗7天后,进行行为学评估、苏木精-伊红染色(hematoxylin-eosin stainingHE)、免疫荧光(ImmunofluorescenceIF)、蛋白印迹(western blotWB)及转录组学分析,转录组学测序数据采用DESeq2软件进行差异基因分析(Version 1.38.3,软件对各个样本基因的数目进行标准化处理,采用basemean 值来估算表达量),计算差异倍数,并采用NB(负二项分布检验的方式)进行差异显著性检验。并通过基因本体(gene ontologyGO)和京都基因与基因组百科全书富集分析(KEGG)进一步探讨其作用机制。结果:与模型组相比,潜阳育阴颗粒剂量依赖性改善神经功能缺损(P0.05)。IF显示,潜阳育阴颗粒明显上调ZO-1P0.01)和Occludin表达,修复BBB,并提高抗炎因子HO-11.9倍,P0.05)和Nrf2水平。WB表明,潜阳育阴颗粒上调HO-1并下调NF-κBP0.01)。转录组学分析发现91个共有差异基因,涉及细胞衰老、吞噬体、坏死性凋亡等炎症相关通路。结论:潜阳育阴颗粒通过抑制炎症、修复BBB促进AIS后神经功能恢复,其机制与调控炎症通路相关,为临床应用提供了理论依据。

Abstract:

Objective: To investigate the role and underlying mechanisms of Qianyang Yinyin granules in promoting neurofunctional recovery after acute ischemic stroke AIS by regulating inflammatory factors and repairing the blood-brain barrier BBB.Methods: Male Sprague-Dawley SD rats were used to establish an AIS model via 90-minute transient middle cerebral artery occlusion tMCAO. The rats were divided into sham operation group model group and low-/high-dose Qianyang Yinyin granules groups. After 7 days of treatment the behavioral assessments hematoxylin-eosin HE staining immunofluorescence IF), Western blot WB), and transcriptomic analysis were performed. For the transcriptomic data DESeq2 software Version 1.38.3 was used to normalize gene counts and estimate expression levels based on basemean values. Fold changes were calculated and differential significance was tested using the negative binomial NB test. Additionally gene ontology GO and Kyoto encyclopedia of genes and genomes KEGG enrichment analyses were conducted to further explore the mechanisms of action.Results: Compared with the model group Qianyang Yinyin granules dose-dependently improved neurological deficits with nearly a 1-fold recovery in the high-dose group P0.05. IF results showed that Qianyang Yinyin granules significantly upregulated the expression of tight junction proteins ZO-1 2.9-fold increase in the low-dose group and 3.2-fold increase in the high-dose groupP0.01 and Occludin thereby repairing the BBB. The granules also increased the expression of anti-inflammatory factors HO-1 1.9-fold increaseP0.05 and Nrf2. WB analysis indicated that Qianyang Yinyin granules upregulated HO-1 and downregulated NF-κB 2.01-fold decrease in the high-dose groupP0.01. Transcriptomic analysis identified 91 common differentially expressed genes which were involved in inflammation-related pathways such as cellular senescence phagosome formation and necroptosis.Conclusion: Qianyang Yinyin granules promote neurofunctional recovery after AIS by inhibiting inflammation and repairing the BBB with mechanisms related to the regulation of inflammatory pathways. These findings provide a theoretical basis for the clinical application of Qianyang Yinyin granules.
