          摘   要  目的  研究丁苯酞对大鼠骨髓间充质干细胞(BMSCs)炎性损伤的改善作用及其可能机制。方法  将大鼠BMSCs分为对
          照组、模型组和丁苯酞低、中、高浓度组(10、20、50 μmol/L)。体外培养BMSCs并采用脂多糖(终浓度为10 mg/L)建立炎性损伤模
          型,经丁苯酞干预后检测细胞存活率、凋亡率和细胞培养液中肿瘤坏死因子α(TNF-α)、白细胞介素1β(IL-1β)、白细胞介素6(IL-
          6)含量以及细胞中核因子 κB(NF-κB)p65 mRNA 和胱天蛋白酶 3(caspase-3)、B 细胞淋巴瘤 2(Bcl-2)、Bcl-2 相关 X 蛋白(Bax)和
          NF-κB p65蛋白表达。结果  与对照组比较,模型组细胞存活率和Bcl-2蛋白表达水平均显著降低(P<0.05);细胞凋亡率,TNF-α、
          IL-1β、IL-6含量,NF-κB p65 mRNA以及caspase-3、Bax、NF-κB p65蛋白表达水平均显著升高(P<0.05)。与模型组比较,丁苯酞
          各浓度组上述指标均显著逆转(P<0.05),且呈浓度依赖性。结论  丁苯酞对脂多糖诱导的BMSCs炎性损伤具有改善作用,其机
          制可能与抑制NF-κB信号通路有关。

          ABSTRACT    OBJECTIVE To study the improvement effect and possible mechanism of N-butylphthalide on inflammatory injury
          of  bone  marrow  mesenchymal  stem  cells (BMSCs)  in  rats.  METHODS  BMSCs  of  rats  were  divided  into  control  group,  model
          group,  N-butylphthalide  low-concentration,  medium-concentration  and  high-concentration  groups (10,  20,  50  μmol/L).  BMSCs
          were  cultured  in  vitro  and  lipopolysaccharide (the  final  concentration  of  10  mg/L)  was  used  to  establish  the  inflammatory  injury
          model. After  the  intervention  of  N-butylphthalide,  the  survival  rate,  apoptotic  rate,  the  contents  of  tumor  necrosis  factor  α (TNF-
          α),  interleukin  1β (IL-1β)  and  IL-6  in  cell  culture  medium,  the  mRNA  expression  of  nuclear  factor-κB(NF-κB)  p65,  and  the
          protein  expressions  of  caspase-3,  B-cell  lymphoma  2 (Bcl-2),  Bcl-2  related  X  protein (Bax)  and  NF- κB  p65  in  cells  were
          detected. RESULTS Compared with control group, the survival rate and protein expression of Bcl-2 were decreased significantly in
          model  group (P<0.05);  the  apoptotic  rate,  contents  of  TNF-α,  IL-1β  and  IL-6,  the  mRNA  expression  of  NF-κB  p65,  and  the
          protein expressions of caspase-3, Bax and NF-κB p65 were increased significantly (P<0.05). Compared with model group, above
          indexes  were  significantly  reversed  in  all  concentration  groups  of  N-butylphthalide (P<0.05),  in  concentration-dependent  manner.
          CONCLUSIONS  N-butylphthalide  can  ameliorate  the  inflammatory  injury  of  BMSCs  induced  by  lipopolysaccharide,  and  its
          mechanism may be related to the inhibition of NF-κB signaling pathway.
