    摘要:

    采用网络药理学、分子对接技术和体内实验,探讨活血通络方(HXTLP)治疗脊髓损伤(SCI)的潜在作用机制。通过TCMSP数据库和Swiss Target Prediction平台检索HXTLP的活性成分与作用靶点,构建“活性成分-靶点”网络。在OMIM、GeneCards 上检索SCI相关靶点,基于STRING数据库建立HXTLP与SCI共同靶点的蛋白互作网络(PPI)。利用Metascape数据库对共同靶点进行KEGG通路富集和GO分析,Autodock1.5.7软件进行活性成分与关键靶点的分子对接,Pymol软件进行结果可视化。最后通过动物实验验证HXTLP治疗SCI的效果。研究共获得184个交集靶点,关键靶点涉及AKT1、STAT3、HSP90AA1、PIK3CA、PIK3R1、HRAS、MAPK1、EGFR等。分子对接结果表明核心活性成分和关键靶点之间具有较高的结合亲和力。动物实验结果显示与模型组相比,HXTLP组对SCI有显著治疗潜力,行为学评分和足迹分析表明小鼠后肢运动功能改善,组织学检查显示损伤区域结构和形态更完整。WB结果显示HXTLP可有效的抑制关键靶点蛋白HSP90AA1和P-STAT3表达,促进P-AKT1的表达。本研究验证了HXTLP有多组成、多靶点、多途径协同作用治疗SCI的特点,为SCI临床用药及进一步研究提供实验理论依据。

    Abstract:

    This study preliminarily investigated the potential mechanisms of the Huoxue Tongluo prescription(HXTLP) in treating spinal cord injury(SCI) through a combination of network pharmacology, molecular docking technology, and in vivo experiment verification. TCMSP database and Swiss Target Prediction platform were utilized to select the active ingredients and targets in HXTLP with therapeutic properties for SCI, and the "active ingredients - targets" network was construted.SCI related targets were searched in OMIM and GeneCards, and the protein interaction network (PPI) of the common targets of HXTLP and SCI was established based on the STRING database. The Metascape database was used for KEGG pathway enrichment and GO analysis of the common targets. Molecular docking of active ingredients and key targets was performed through Autodock1.5.7 software and the results were visualized by Pymol software. Finally, the effect of HXTLP on SCI was verified by animal experiments.The results indicated that A total of 184 intersection targets were obtained, and the key targets were AKT1, STAT3, HSP90AA1, PIK3CA, PIK3R1, HRAS, MAPK1, EGFR, etc. Molecular docking results showed a strong binding ability between the core active components and key targets. Animal experimental results showed that HXTLP group had significant therapeutic potential for SCI compared with model group. Behavioral scores and footprint analysis showed improved hind limb motor function, and histological examination showed more complete structure and morphology of the injured area.WB result revealed that HXTLP can effectively inhibit the key target protein HSP90AA1 and the expression of P-STAT3, promoted the expression of P-AKT1. This study verifies that HXTLP has the characteristics of multi-component, multi-target and multi-pathway synergistic effect in the treatment of SCI, and provides experimental theoretical basis for clinical medication and further research of SCI.
