基于体素形态学分析针刺干预缺血性脑卒中肢体运动功能障碍的作用机制研究

基于体素形态学分析针刺干预缺血性脑卒中肢体运动功能障碍的作用机制研究摘要：

目的：研究基于体素形态学分析的针刺干预对缺血性脑卒中肢体运动功能障碍的作用机制，探讨其对神经元、神经元胶质细胞及血管系统的影响。

方法：建立大鼠缺血性脑卒中模型，并分为针刺组、假针刺组和未处理组。进行7天针刺干预后，采用三维重构技术及HE、Nissl、GFAP染色法对各组进行比较分析。

结果：针刺组肢体运动功能得到明显改善，神经元形态和数量有所恢复，GFAP阳性细胞减少，血管移位得到改善，与未处理组和假针刺组相比均有明显差异。

结论：基于体素形态学分析的针刺干预可以促进神经元细胞的修复和复苏，减少神经胶质细胞反应，改善血管系统结构，从而有利于缺血性脑卒中后肢体功能的恢复。

Abstract:

Objective:Toexplorethemechanismofvoxel-basedmorphometryanalysiscombinedwithacupunctureinterventiononthemotordysfunctionoflimbafterischemicstroke,andtoinvestigateitseffectsonneurons,glialcellsandvascularsystem.

Methods:Aratmodelofischemicstrokewasestablishedanddividedintoacupuncturegroup,shamacupuncturegroupanduntreatedgroup.After7daysofacupunctureintervention,three-dimensionalreconstructiontechnology,HEstaining,NisslstainingandGFAPstainingwereusedforcomparativeanalysis.

Results:Themotorfunctionoftheacupuncturegroupimprovedsignificantly,themorphologyandnumberofneuronswererestored,thenumberofGFAPpositivecellsdecreased,andthebloodvesseldisplacementimproved,whichwereallsignificantlydifferentfromthoseoftheuntreatedgroupandtheshamacupuncturegroup.

Conclusion:Voxel-basedmorphometryanalysiscombinedwithacupunctureinterventioncanpromotetherepairandrecoveryofneuronalcells,reduceglialcellreactions,andimprovethestructureofthevascularsystem,whichisconducivetotherecoveryoflimbfunctionafterischemicstroke.
