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.
