          摘  要  目的  研究麻黄碱对脂多糖(LPS)诱导的小胶质细胞功能损伤的修复作用及机制。方法  以人小胶质细胞HMC3为研究
          对象,考察不同质量浓度麻黄碱(75、150、300、600 μg/mL)对HMC3细胞活力和凋亡的影响。然后将HMC3细胞分为对照组(不
          受药物干预)、LPS组(1 μg/mL)、麻黄碱组(1 μg/mL LPS+300 μg/mL麻黄碱)、BAY11-7082组[1 μg/mL LPS+5 μmol/L核因子κB
         (NF-κB)信号通路抑制剂BAY11-7082]、抑制剂组(1 μg/mL LPS+300 μg/mL麻黄碱+5 μmol/L BAY11-7082)和激活剂组(1 μg/mL
          LPS+300 μg/mL麻黄碱+1 μmol/L NF-κB信号通路激活剂Prostratin),加入相应药物作用24 h后,检测细胞迁移能力和细胞中可溶
          性白细胞介素6(sIL-6)、白细胞介素10(IL-10)、超氧化物歧化酶(SOD)、丙二醛(MDA)水平以及NF-κB信号通路相关蛋白表达水
          平。结果  300 μg/mL的麻黄碱可使HMC3细胞活力显著升高、凋亡率显著降低(P<0.05)。与对照组相比,LPS组迁移细胞数显
          著增多,细胞中sIL-6、MDA水平和NF-κB蛋白磷酸化水平均显著升高,IL-10、SOD水平均显著降低(P<0.05)。与LPS组相比,麻
          黄碱组和 BAY11-7082 组上述指标水平均显著逆转(P<0.05)。与麻黄碱组相比,抑制剂组迁移细胞数显著减少,细胞中 sIL-6、
          MDA 水平和 NF-κB 蛋白磷酸化水平均显著降低,IL-10、SOD 水平均显著升高(P<0.05);而激活剂组上述指标水平均显著逆转
         (P<0.05)。结论  麻黄碱可通过抑制LPS诱导的HMC3细胞凋亡、迁移、炎症和氧化应激,修复细胞功能损伤,其作用机制可能与
          抑制NF-κB信号通路活性有关。

          ABSTRACT   OBJECTIVE To study the repair effect of ephedrine on lipopolysaccharide (LPS)-induced microglia function injury
          and its mechanism. METHODS Human microglia cells (HMC3) were used as research objects to investigate the effects of different
          concentrations  of  ephedrine (75,  150,  300,  600  μg/mL)  on  the  viability  and  apoptosis  of  HMC3  cells.  HMC3  cells  were  divided
          into  control  group (without  drug  intervention),  LPS  group (1  μg/mL),  ephedrine  group (1  μg/mL  LPS+300  μg/mL  ephedrine),
          BAY11-7082  group  [1  μg/mL  LPS+5  μmol/L  nuclear  factor- κB (NF- κB)  pathway  inhibitor  BAY11-7082],  inhibitor  group (1
          μg/mL  LPS+300  μg/mL  ephedrine+5  μmol/L  BAY11-7082)  and  activator  group (1  μg/mL  LPS+300  μg/mL  ephedrine+1  μmol/L
          NF-κB  pathway activator Prostratin). After 24  hours  of  drug  treatment,  cell migration,  the levels of  soluble interleukin-6(sIL-6),
          interleukin-10(IL-10),  superoxide  dismutase(SOD)and  malondialdehyde(MDA),  and  the  expressions  of  NF-κB  pathway-related
          proteins were all detected. RESULTS The viability of HMC3 cells could be increased significantly by 300 μg/mL ephedrine, while
          the  apoptotic  rate  was  decreased  significantly (P<0.05).  Compared  with  the  control  group,  the  number  of  migrating  cells  was
          increased  significantly  in  the  LPS  group;  the  levels  of  sIL-6  and  MDA,  the  phosphorylation  of  NF- κB  protein  were  increased
          significantly, while the levels of IL-10 and SOD were decreased significantly (P<0.05). Compared with the LPS group, the above
          indexes were reversed significantly in the ephedrine group and BAY11-7082 group (P<0.05). Compared with the ephedrine group,
                                                             the  number  of  migrating  cells  was  decreased  significantly  in
