Abstract:
Objective:To study the efficacy of Alteplase in repairing T-lymphocyte mediated brain tissue immunoinflammatory damage after acute ischemic stroke(AIS).Methods:A total of 100 patients with AIS admitted to Hengshui People's Hospital from June 2022 to June 2023 were selected,and divided into regular group and Alteplase group,with 50 cases in each group,after enroll-ment,the regular group received routine intervention treatment,while the Ateplase group received thrombolytic therapy with Ateplase.Compared changes in neurological function,cerebrovascular reserve function,cerebral hemodynamics,T lymphocytes mediated brain tissue immunoinflammatory damage indicators CD4+T cell subsets[pro-inflammatory cells(Th1,Th17),anti-inflammatory cells(Th2,Treg cells)]and related cytokines levels between two groups of patients,and evaluated clinical efficacy and prognosis.Results:After treatment,NIHSS score of Alteplase group was lower than that of regular group[(6.57±0.79)points vs(9.34±1.23)points,t=13.400,P<0.05].CVR and BHI of cerebral vascular reserve in Alteplase group were higher than those in regular group[(34.54±4.35)%vs(29.89±2.31)%,1.00±0.23 vs 0.92±0.08,t=6.676,2.323,P<0.05],PI was lower than that of regular group(0.60±0.07 vs 0.72±0.08,t=7.982,P<0.05).Cerebral hemodynamic CBF of Alteplase group was higher than that of regular group[(49.89±9.76)ml/(100 g/min)vs(40.34±7.86)ml/(100 g/min),t=5.389,P<0.05].MTT and TTP were shorter than those in regular group[(6.45±0.78)s vs(9.78±1.02)s,(24.45±2.16)s vs(26.78±3.25)s,t=18.340,4.222,P<0.05].Proportion of Th1 and Th17 cells and levels of IFN-γ and IL-17 in Ateplase group were lower than those in regular group[(3.27±0.59)%vs(5.64±0.52)%,(2.34±0.25)%vs(4.35±0.38)%,(3.24±0.45)pg/ml vs(4.90±0.65)pg/ml,(10.23±1.43)pg/ml vs(14.35±2.14)pg/ml,t=21.310,31.250,14.850,11.320,P<0.05),proportion of Th2 and Treg cells and levels of IL-4 and TGF-β were higher than those in regular group[(8.75±0.54)%vs(7.02±0.37)%,(7.24±2.13)%vs(5.88±1.67)%,(13.24±2.16)pg/ml vs(10.26±1.29)pg/ml,(90.32±9.02)pg/ml vs(81.45±8.97)pg/ml,t=18.690,3.553,8.375,4.930,P<0.05].Total effective rate and good prognosis rate of Alteplase group were higher than those of regular group(94.00%vs 80.00%,80.00%vs 62.00%,χ2=4.332,3.934,P<0.05).Conclu-sion:In treatment of AIS,Alteplase has effect of repairing the immune inflammation injury of brain tissue mediated by T lymphocytes,alleviating brain injury,improving cerebrovascular reserve function and nerve function,and the prognosis is good.
