摘 要 目的 探究利舒康胶囊调节低氧诱导因子1α(HIF-1α)/核因子κB(NF-κB)信号通路对大鼠低氧性肺动脉高压(HPAH)的
影响。方法 60只大鼠随机分为对照组、模型组、阳性对照组(西地那非30 mg/kg)和利舒康低、中、高剂量组(利舒康胶囊6、12、18
g/kg),每组10只。除对照组外,其余各组大鼠采用间歇性低氧法(模拟5 000 m海拔)建立HPAH模型;建模同时每日灌胃相应药
物或生理盐水,连续28 d。末次给药24 h内,检测大鼠平均肺动脉压(MPAP)和右心室肥厚指数(RVHI),观察肺组织病理情况,检
测肺组织中α平滑肌肌动蛋白(α-SMA)表达和HIF-1α、NF-κB mRNA表达,以及HIF-1α、NF-κB p65蛋白表达情况。结果 与模
型组比较,利舒康中、高剂量组和阳性对照组大鼠的MPAP、RVHI均显著降低(P<0.05);肺组织中α-SMA表达和HIF-1α、NF-κB
mRNA 表达,以及 HIF-1α 和 NF-κB p65 蛋白表达均显著下调(P<0.05);肺血管重塑均不同程度改善。结论 利舒康胶囊对大鼠
HPAH具有改善作用,其机制可能与抑制HIF-1α/NF-κB信号通路有关。

ABSTRACT OBJECTIVE To explore the effects of Lishukang capsules on hypoxic pulmonary artery hypertension (HPAH) rats
by regulating the HIF-1α/NF- κB signaling pathway. METHODS Sixty rats were randomly divided into control group, model
group, positive control group (sildenafil, 30 mg/kg), Lishukang low-, medium- and high-dose groups (Lishukang capsules 6, 12,
18 g/kg), with 10 rats in each group. Except for control group, the HPAH model was induced by intermittent hypoxia method
(simulating an altitude of 5 000 m) in other groups; at the same time, they were given relevant medicine or normal saline
intragastrically, for consecutive 28 days. Within 24 hours of the last administration, the mean pulmonary artery pressure (MPAP)
and right ventricule hypertrophy index (RVHI) of rats were detected; pathological morphology of lung tissue was observed, and
the expression of α-smooth muscle actin (α-SMA), mRNA expressions of HIF-1α and NF-κB as well as protein expressions of
HIF-1α and NF-κB p65 in lung tissue were determined. RESULTS Compared with model group, MPAP and RVHI in Lishukang
medium- and high-dose groups and positive control group were all decreased significantly (P<0.05); the expression of α-SMA,
mRNA expressions of HIF-1α and NF-κB, and protein expressions of HIF-1α and NF-κB p65 in lung tissue were all decreased
significantly (P<0.05); additionally, pulmonary vascular remodeling was improved to varying degrees. CONCLUSIONS
Lishukang capsules may protect HPAH rats, the mechanism of which may be associated with inhibiting the HIF-1α/NF- κB
signaling pathway.
