基于體素形態(tài)學分析針刺干預缺血性腦卒中肢體運動功能障礙的作用機制研究

基于體素形態(tài)學分析針刺干預缺血性腦卒中肢體運動功能障礙的作用機制研究摘要：

目的：研究基于體素形態(tài)學分析的針刺干預對缺血性腦卒中肢體運動功能障礙的作用機制，探討其對神經(jīng)元、神經(jīng)元膠質細胞及血管系統(tǒng)的影響。

方法：建立大鼠缺血性腦卒中模型，并分為針刺組、假針刺組和未處理組。進行7天針刺干預后，采用三維重構技術及HE、Nissl、GFAP染色法對各組進行比較分析。

結果：針刺組肢體運動功能得到明顯改善，神經(jīng)元形態(tài)和數(shù)量有所恢復，GFAP陽性細胞減少，血管移位得到改善，與未處理組和假針刺組相比均有明顯差異。

結論：基于體素形態(tài)學分析的針刺干預可以促進神經(jīng)元細胞的修復和復蘇，減少神經(jīng)膠質細胞反應，改善血管系統(tǒng)結構，從而有利于缺血性腦卒中后肢體功能的恢復。

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.
