目的 观察银杏二萜内酯葡胺(GDLM)治疗急性脑梗死患者外周血T细胞亚群的改变,并通过小鼠体内实验观察其对T细胞亚群的影响.方法 选取2018-2019年兰州大学第一医院神经内科收治的急性脑梗死患者80例,根据接受治疗方案的不同分为观察组和对照组.两组患者均接受标准治疗,观察组加用GDLM治疗.比较两组患者临床疗效和卒中量表评分(NHISS)、血清C反应蛋白(CRP)水平、外周血Th17细胞水平变化.将C57B/L6雄性小鼠分为PBS组和GDLM两组,分别给予腹腔注射PBS或GDLM,第5、10天分析小鼠脾、引流淋巴结细胞中Th17细胞的改变.结果 治疗前,两组患者NIHSS评分及血清CD4+T细胞基线水平之间的差异无统计学意义(P>0.05);治疗后,两组患者CD4+T细胞均较治疗前无明显变化,但血清CRP水平、CD4+IL-17A+T细胞(Th17细胞)均较治疗前降低(P<0.05);治疗后,观察组NIHSS评分低于对照组(P<0.05).注射后第5天,GDLM组小鼠脾CD4+CD44lowCD62Lhigh T细胞显著增加,差异有统计学意义(P<0.05),到第10天,GDLM组CD4+CD44lowCD62Lhigh T细胞仍略高于对照组.注射后5天,GDLM组小鼠脾Th17细胞表现出降低趋势,第10天时则明显低于对照组(P<0.05).结论 GDLM治疗急性脑梗死效果显著,其机制可能是通过调节患者外周血T细胞亚群水平,抑制T细胞活化,抑制Th17细胞分化进而改善神经功能障碍.
Changes in Th17 cell subsets in peripheral blood of patients with acute cerebral infarction treated with ginkgo diterpene lactone meglumine and its relationship with clinical prognosis
Objective To observe the T cell subsets in peripheral blood of patients with subacute cerebral infarction treated by Ginkgo diterpene lactone meglumine(GDLM).The effect of GDLM on T cell subsets was also observed in mice.Methods 80 patients with subacute cerebral infarction were included in Depart-ment of Neurology,The First Hospital of Lanzhou University,and were divided into two groups:the control group and the observction group.The control group received conventional treatment,and the observation group was treated with conventional treatment and GDLM.Clinical efficacy,neurological function,national institute of hea-lth stroke scores(NIHSS),level of CRP in serum,and frequency of Th17 cell subsets were compared between the two groups.In addition,C57B/L6 male mice were divided into a PBS and GDLM group.Mice were given intraperitoneal injection of PBS or GDLM and T cell subsets in spleen and draining lymph node were analyzed by FACS.Result Before treatment,there were no significant difference in NIHSS and serum CD4+T cell levels between the two groups(P>0.05).After treatment,CD4+T cell in both groups underwent no significant changes.But the level of serum CRP,frequency of CD4+IL-17A+T cells(Th17 cell)were decreased(P<0.05).Besides,NIHSS in the observation group were lower than those in the control group(P<0.05).To examine whether GDLM treatment in naïve mice alters Th17 and other T cell subsets in vivo,we intraperitoneally injected GDLM into naïve B6 male mice for 10 consecutive days.On day 5,CD4+CD44low CD62Lhigh T cells in GDLM group were significantly increased compared to that control group(P<0.05).And on day 10,CD4+CD44low CD62Lhigh T cells in GDLM group were still slightly higher.On day 5,splenic Th17 cells in GDLM group showed a decreasing trend,and were significantly lower than control group on day 10(P<0.05).Conclusion The GDLM had positive effect on subacute cerebral infarction,for which the regulation of the peripheral blood T cell subsets,especially the inhibitions of T cell activation and Th17 cell differentiation,should possibly be considered.
