摘 要 目的 研究八味沉香散含药血清对H9c2细胞氧糖剥夺损伤的保护机制。方法 将H9c2细胞分为空白组、模型组和八味
沉香散低、中、高剂量组(含药血清剂量依次为2.5、8、12 g/kg)。体外培养H9c2细胞并建立氧糖剥夺损伤模型,含药血清干预后检
测细胞存活率,观察细胞形态,检测生化指标乳酸脱氢酶(LDH)、肌酸激酶(CK)、超氧化物歧化酶(SOD)、过氧化氢酶(CAT)、呼
吸链复合酶Ⅰ(ComplexⅠ)、谷胱甘肽过氧化物酶(GSH-Px)和丙二醛(MDA)水平,检测细胞内活性氧(ROS)含量、线粒体膜电位
和细胞凋亡情况,检测氧化应激相关蛋白[Kelch 样 ECH 关联蛋白 1(Keap1)、核转录因子 E2 相关因子 2(Nrf2)、血红素加氧酶 1
(HO-1)、NADH氧化还原酶辅酶10(Ndufa10)、硫氧还蛋白(Trx)]、凋亡相关蛋白[B细胞淋巴瘤2(Bcl-2)、Bcl-2相关X蛋白(Bax)、
胱天蛋白酶3(Caspase-3)和细胞色素C(Cytc)]的表达。结果 与空白组比较,模型组细胞形态破损,LDH、CK和MDA水平均显著
升高(P<0.01),CAT、ComplexⅠ、SOD、GSH-Px水平和线粒体膜电位均显著降低(P<0.01),细胞内ROS含量和凋亡率均显著升
高(P<0.01),氧化应激相关蛋白(Keap1、Nrf2、HO-1、Ndufa10和Trx)和促凋亡相关蛋白(Bax、Caspase-3、Cytc)表达水平均显著升
高(P<0.05),抗凋亡蛋白Bcl-2表达水平显著降低(P<0.05)。给予八味沉香散含药血清后,细胞形态改善,以上指标大部分显著

ABSTRACT OBJECTIVE To study the protective mechanism of Bawei chenxiang powder containing serum on H9c2 cells
injured by oxygen-glucose deprivation (OGD). METHODS H9c2 cells were divided into blank group, model group and Bawei
chenxiang powder low-dose, medium-dose and high-dose groups (the dose of drug containing serum 2.5, 8, 12 g/kg). H9c2 cells
were cultured in vitro to establish OGD model. After intervention with drug-containing serum, survival rate of cell was detected.
The cell morphology was observed; the levels of lactate dehydrogenase (LDH), creatine kinase (CK), superoxide dismutase
(SOD), catalase (CAT), respiratory chain complex Ⅰ (Complex Ⅰ), glutathione peroxidase (GSH-Px) and malondialdehyde
(MDA) were detected. The contents of reactive oxygen species (ROS), mitochondrial membrane potential and apoptosis were also
detected. The expressions of oxidative stress-related proteins [Kelch ECH association protein 1 (Keap1), nuclear factor erythroid 2-
related factor 2 (Nrf2), heme oxygenase 1 (HO-1), NADH oxidoreductase coenzyme 10 (Ndufa10), thioredoxin (Trx)] and
apoptosis-related proteins [B-cell lymphoma 2 (Bcl-2), Bcl-2 associated X protein (Bax), Caspase-3 and cytochrome C (Cytc)]
were detected. RESULTS Compared with blank group, the cell morphology of model group was damaged; the levels of LDH, CK
and MDA were significantly increased (P<0.01), while the levels of CAT, ComplexⅠ, SOD and GSH-Px and mitochondrial
membrane potential were significantly decreased (P<0.01). The content of intracellular ROS and apoptotic rate were significantly
increased (P<0.01); the expressions of oxidative stress-related proteins (Keap1, Nrf2, HO-1, Ndufa10 and Trx) and pro-
apoptosis proteins (Bax, Caspase-3 and Cytc) were significantly increased (P<0.05), while the expression of anti-apoptotic
protein Bcl-2 was significantly decreased (P<0.05). After
