摘 要 目的 研究牛膝-杜仲药对的抗炎作用。方法 将小鼠巨噬细胞RAW264.7分为空白组、模型组、牛膝组(800 μg/mL)、杜仲
组(800 μg/mL)和牛膝-杜仲药对低、中、高浓度组(400、800、1 600 μg/mL),除空白组和模型组外,其余各组加入相应药物培养6 h
后,空白组继续加入培养基,模型组加入10 μg/mL 脂多糖(以复制炎症模型),其余各组加入相应药物和10 μg/mL 脂多糖。检测各
组细胞中炎症因子[一氧化氮(NO)、白细胞介素1β(IL-1β)、IL-6、肿瘤坏死因子α(TNF-α)]的水平,并采用金氏公式评价牛膝、杜仲
的联合作用;检测细胞中诱导型一氧化氮合酶(iNOS)、环氧合酶2(COX-2)、核因子κB(NF-κB)抑制蛋白α(IκBα)的表达水平和
NF-κB p65、IκB激酶(IKK)、p38丝裂原激活的蛋白激酶(p38 MAPK)、胞外信号调节激酶(ERK)、c-Jun N端激酶(JNK)的磷酸化
水平。结果 与空白组比较,模型组细胞中炎症因子水平以及 iNOS、COX-2 蛋白表达水平和 NF-κB p65、IKK、p38 MAPK、ERK、
JNK蛋白磷酸化水平均显著升高(P<0.01),IκBα蛋白的表达水平显著降低(P<0.01);经牛膝-杜仲药对干预后,细胞中炎症因子
水平以及上述蛋白的表达水平或磷酸化水平大部分显著逆转(P<0.05或P<0.01),且牛膝-杜仲药对具有协同作用。结论 牛膝-
杜仲药对对RAW264.7细胞具有协同抗炎作用,其作用机制可能与抑制NF-κB/MAPK信号通路相关蛋白表达有关。

ABSTRACT OBJECTIVE To study the anti-inflammatory effect of couplet medicinals of Achyranthes bidentata-Eucommia
ulmoides. METHODS Mouse macrophage RAW264.7 were divided into blank group,model group,A. bidentata group (800
μg/mL),E. ulmoides group(800 μg/mL)and low-,medium- and high- concentration groups of couplet medicinals of A. bidentata-
E. ulmoides(400,800,1 600 μg/mL). Excep for blank group and model group,the other groups were added with corresponding
drugs for 6 hours;then blank group was continued to add into the medium,while model group was added into 10 μ g/mL
lipopolysaccharide (to induce the inflammatory model);other groups were added into corresponding drugs and 10 μ g/mL
lipopolysaccharide. The levels of inflammatory factors [nitric oxide(NO),interleukin-1β(IL-1β),IL-6,tumor necrosis factor-α
(TNF-α)] were detected,and Jin’s formula was used to evaluate the effects of A. bidentata-E. ulmoides. The expression of
inducible nitric oxide synthase(iNOS),cyclooxygenase-2(COX-2),nuclear factor kappa-B(NF-κB)and inhibitor α of NF-κB
(IκBα)as well as the phosphorylation of NF-κB p65,IκB kinase(IKK),p38 mitogen-activated protein kinase(p38 MAPK),
extracellular signal-regulated kinase(ERK)and c-Jun N-terminal kinase(JNK)were determined. RESULTS Compared with blank
group,the level of inflammatory factors,protein expression of iNOS and COX-2 as well as the phosphorylation of NF-κB p65,
IKK,p38 MAPK,ERK and JNK were increased significantly(P<0.01),while the protein expression of IκBα was decreased
significantly(P<0.01). After intervention of couplet medicinals of A. bidentata-E. ulmoides,the level of inflammatory factors,the
expression or phosphorylation of above proteins were reversed significantly(P<0.05 or P<0.01),and couplet medicinals of A.
bidentata-E. ulmoides had a synergistic effect. CONCLUSIONS The couplet medicinals of A. bidentata-E. ulmoides have
synergistic anti-inflammatory effect on RAW264.7 cells. Its mechanism may be related to the inhibition of NF-κB/MAPK signaling
pathway related protein expression.
