          摘  要  目的  探究连翘醇提物对肺癌NCI-H226细胞增殖、迁移、侵袭的影响。方法  以肺癌NCI-H226细胞为研究对象,将细胞
          分为对照组,连翘醇提物低、中、高浓度组(5、10、20 mg/mL),激活剂组[10 mg/mL连翘醇提物+0.5 μmol/L核因子κB(NF-κB)信号
          通路激活剂PMA],抑制剂组(10 mg/mL连翘醇提物+10 μmol/L NF-κB信号通路抑制剂BAY 11-7082),阳性对照组(20 μg/mL顺
          铂),除对照组细胞不作干预外,其余各组细胞加入相应药物培养24 h。检测细胞增殖、迁移、侵袭情况,并计算增殖率、迁移率、侵
          袭细胞数;检测细胞中NF-κB p65、NF-κB抑制蛋白α(IκBα)、磷酸化NF-κB p65(p-NF-κB p65)、磷酸化IκBα(p-IκBα)蛋白表达水
          平。结果  与对照组比较,连翘醇提物各浓度组和阳性对照组细胞的增殖率、迁移率、侵袭细胞数以及细胞中p-IκBα、p-NF-κB p65
          蛋白表达水平均显著降低(P<0.05);与连翘醇提物中浓度组比较,抑制剂组细胞增殖率、迁移率、侵袭细胞数及细胞中上述蛋白
          表达水平均显著降低(P<0.05),而激活剂组均显著升高(P<0.05)。结论  连翘醇提物可抑制肺癌NCI-H226细胞增殖、迁移和侵
          袭,其作用机制可能与抑制NF-κB信号通路有关。

          ABSTRACT   OBJECTIVE  To  investigate  the  effects  of  Forsythia  suspensa  ethanol  extract  on  the  proliferation,  migration  and
          invasion  of  lung  cancer  cells  NCI-H226.  METHODS  As  research  objects,  lung  cancer  cells  NCI-H226  were  divided  into  control
          group, F. suspensa ethanol extract low-, medium- and high-concentration groups (5, 10, 20 mg/mL), activator group [10 mg/mL
          F.  suspensa  ethanol  extract+0.5  μmol/L  nuclear  factor  kappa  B (NF-κB)  signaling  pathway  activator  PMA],  inhibitor  group (10
          mg/mL  F.  suspensa  ethanol  extract+10  μmol/L  NF-κB  signaling  pathway  inhibitor  BAY  11-7082)  and  positive  control  group (20
          μg/mL  cisplatin).  Except  for  the  control  group  of  cells  without  intervention,  all  other  groups  of  cells  were  cultured  with
          corresponding  drugs  for  24  hours;  the  proliferation,  migration  and  invasion  of  cells  were  all  detected,  and  the  proliferation  rate,
          migration rate, and the number of invading cells were also calculated; protein expressions of NF-κB p65, NF-κB inhibitory protein α
         (IκBα),  phosphorylated  NF-κB  p65 (p-NF-κB  p65)  and  phosphorylated  IκBα (p-IκBα)  were  determined.  RESULTS  Compared
          with control group, the proliferation rate, migration rate, and the number of invading cells as well as the protein expressions of p-
          IκBα  and  p-NF-κB  p65  were  decreased  significantly  in  F.  suspensa  ethanol  extract  groups  and  positive  control  group (P<0.05).
          Compared  with  F.  suspensa  ethanol  extract  medium-concentration  group,  the  proliferation  rate,  migration  rate,  and  the  number  of
          invading  cells  as  well  as  above  protein  expressions  were  all  decreased  significantly  in  inhibitor  group (P<0.05),  while  those  of
          activator  group  were  increased  significantly (P<0.05).  CONCLUSIONS  F.  suspensa  ethanol  extract  can  inhibit  the  proliferation,
          migration  and  invasion  of  lung  cancer  cells  NCI-H226,  and  the  mechanism  of  which  may  be  related  to  the  inhibition  of  NF-κB
          signaling pathway.
