OBJECTIVE To investigate the protective effect and possible mechanism of Chaihu Shugan Granules on acute liver injury in mice. METHODS Chaihu Shugan Granules was administered to mice at low, medium and high dosages (crude drug dose: 11.4, 22.8, 45.6 g·kg-1) continuously for 7 d. Two hours after the last administration, the animal model was made with 0.2% tetrachloromethane (CCl4) solution except the control group. The serum and liver tissues were collected after 12 h. The levels of serum alanine aminotransferase (ALT), aspartate aminotransferase (AST) and superoxide dismutase (SOD), malondialdehyde (MDA), interleukin 6 (IL-6), tumor necrosis factor α (TNF-α) and reactive oxygen species (ROS) in liver tissues were measured by ELISA. HE staining was conducted to reveal the histopathological changes in liver. Transcriptomics was used to obtain differentially expressed mRNA in liver tissues and enrich differentially expressed pathways, while metabolomics was used to obtain changes in liver endogenous metabolites and enriches pathways of differential metabolites using KEGG database. The expression and location of c-Jun N-terminal kinase (JNK), p38 mitogen-activated protein kinase (p38 MARK), kelch-like ECH-associated protein 1 (Keap1), nuclear factor erythroid 2-related factor 2 (Nrf2) and heme oxygenase-1 (HO-1) in liver tissues were measured by immunohistochemistry and Western blot. RESULTS Compared with the model group, the serum levels of ALT, AST and MDA, IL-6, TNF-α and ROS in liver tissues of mice in each group of Chaihu Shugan Granules decreased significantly (P<0.05 or P<0.01), while the level of SOD in liver tissues increased significantly (P<0.01). The degree of necrosis and inflammatory infiltration in liver cells decreased significantly. Nqo1 gene and NAD(P)H: quinone oxidoreductase 1 (NQO1) expression were up-regulated while Ccl2 gene and monocyte chemotactic protein 1 (MCP-1) expression were down-regulated. Organic acids were significantly down-regulated and carbohydrate was significantly up-regulated, the expressions of JNK, p38 MARK and Keap1 in liver tissues were significantly decreased (P<0.05 or P<0.01), while the expressions of Nrf2 and HO-1 were significantly increased (P<0.01). CONCLUSION Chaihu Shugan Granules might have protective effect on CCl4-induced acute liver injury in mice by activating the Keap1-Nrf2/HO-1 signal pathway.

目的 探讨柴胡疏肝颗粒对小鼠急性肝损伤的保护作用及可能机制。方法 将柴胡疏肝颗粒按低、中、高(生药量:11.4、22.8、45.6 g·kg-1)3个剂量连续给药7 d,末次给药2 h后,除正常对照组外,用体积分数0.2% 四氯化碳(tetrachloromethane,CCl4)溶液造模,12 h后,收集小鼠的血清和肝组织,制作肝组织病理切片。测定血清中丙氨酸氨基转移酶(alanine aminotransferase,ALT)、天门冬氨酸氨基转移酶(aspartate aminotransferase,AST)和肝组织中超氧化物歧化酶(superoxide dismutase,SOD)、丙二醛(malondialdehyde,MDA)、白细胞介素6(interleukin 6,IL-6)、肿瘤坏死因子α(tumor necrosis factor α,TNF-α),以及活性氧自由基(reactive oxygen species,ROS)含量;转录组学获得肝脏组织差异表达mRNA并富集与差异表达基因显著相关的通路;代谢组学研究肝组织中内源性代谢物变化并进行通路富集分析;免疫组织化学法及Western blot法检测肝组织中c-Jun氨基末端激酶(c-Jun N-terminal kinase,JNK)、p38丝裂原活化蛋白激酶(p38 mitogen-activated protein kinase,p38 MARK)、Kelch样ECH关联蛋白1(kelch-like ECH-associated protein 1,Keap1)、核因子E2相关因子2(nuclear factor erythroid 2-related factor 2,Nrf2)、血红素加氧酶-1(heme oxygenase-1,HO-1)表达及定位情况。结果 与模型组比较,柴胡疏肝颗粒能显著降低小鼠血清ALT、AST和肝组织MDA、IL-6、TNF-α及ROS水平(P<0.05或P<0.01),显著升高肝组织中SOD水平(P<0.01),明显减轻肝细胞坏死及炎性浸润程度;上调Nqo1基因,上调醌氧化还原酶1[NAD(P)H: quinone oxidoreductase 1,NQO1]表达;下调Ccl2基因,下调单核细胞趋化蛋白-1(monocyte chemotactic protein 1,MCP-1)表达,且代谢物中有机酸类显著下调,糖类显著上调。肝组织中JNK、p38 MARK、Keap1表达均显著下调(P<0.05或P<0.01),Nrf2、HO-1表达显著上调(P<0.01)。结论 柴胡疏肝颗粒可能通过激活Keap1-Nrf2/HO-1信号通路,对CCl4诱导的小鼠急性肝损伤具有保护作用。

OBJECTIVE To investigate the protective effect and possible mechanism of Chaihu Shugan Granules on acute liver injury in mice. METHODS Chaihu Shugan Granules was administered to mice at low, medium and high dosages (crude drug dose: 11.4, 22.8, 45.6 g·kg-1) continuously for 7 d. Two hours after the last administration, the animal model was made with 0.2% tetrachloromethane (CCl4) solution except the control group. The serum and liver tissues were collected after 12 h. The levels of serum alanine aminotransferase (ALT), aspartate aminotransferase (AST) and superoxide dismutase (SOD), malondialdehyde (MDA), interleukin 6 (IL-6), tumor necrosis factor α (TNF-α) and reactive oxygen species (ROS) in liver tissues were measured by ELISA. HE staining was conducted to reveal the histopathological changes in liver. Transcriptomics was used to obtain differentially expressed mRNA in liver tissues and enrich differentially expressed pathways, while metabolomics was used to obtain changes in liver endogenous metabolites and enriches pathways of differential metabolites using KEGG database. The expression and location of c-Jun N-terminal kinase (JNK), p38 mitogen-activated protein kinase (p38 MARK), kelch-like ECH-associated protein 1 (Keap1), nuclear factor erythroid 2-related factor 2 (Nrf2) and heme oxygenase-1 (HO-1) in liver tissues were measured by immunohistochemistry and Western blot. RESULTS Compared with the model group, the serum levels of ALT, AST and MDA, IL-6, TNF-α and ROS in liver tissues of mice in each group of Chaihu Shugan Granules decreased significantly (P<0.05 or P<0.01), while the level of SOD in liver tissues increased significantly (P<0.01). The degree of necrosis and inflammatory infiltration in liver cells decreased significantly. Nqo1 gene and NAD(P)H: quinone oxidoreductase 1 (NQO1) expression were up-regulated while Ccl2 gene and monocyte chemotactic protein 1 (MCP-1) expression were down-regulated. Organic acids were significantly down-regulated and carbohydrate was significantly up-regulated, the expressions of JNK, p38 MARK and Keap1 in liver tissues were significantly decreased (P<0.05 or P<0.01), while the expressions of Nrf2 and HO-1 were significantly increased (P<0.01). CONCLUSION Chaihu Shugan Granules might have protective effect on CCl4-induced acute liver injury in mice by activating the Keap1-Nrf2/HO-1 signal pathway.

肝脏是调节体内代谢和解毒的重要器官,极易受药物或环境等外界因素影响造成肝损伤,严重的发展成肝癌,危害人类健康。肝病目前已经成为影响人类健康的最常见疾病之一,寻找有效的防治药物来应对因各种原因所致的肝损伤,也成为目前研究的热点。近年来中医药在肝损伤防治研究方面取得很多进展,研究表明中药可通过抗氧自由基损伤、抑制脂质过氧化反应、降低炎症反应和凋亡介质产生等方面改善肝损伤[1-3]

与正常对照组比较,模型组小鼠肝组织JNK、p38 MARK、Keap1蛋白表达均显著升高(P<0.01),且集中在肝细胞坏死组织附近;Nrf2、HO-1蛋白表达均显著降低(P<0.01)。与模型组比较,柴胡疏肝颗粒各剂量组小鼠肝组织JNK、p38 MARK、Keap1蛋白表达均显著降低(P<0.05或P<0.01),Nrf2、HO-1蛋白表达均显著升高(P<0.01)。结果见图5

研究表明,CCl4诱导肝损伤与氧化应激相关。CCl4在体内经肝细胞色素P450代谢活化,生成三氯甲基自由基和氯自由基。自由基促使肝细胞膜上的磷脂分子发生脂质过氧化反应,产生的氧自由基增多,与细胞膜的脂质和蛋白质以共价键结合,破坏细胞膜结构导致功能丧失[5-6];同时,组织内抗氧化损伤酶(如SOD等)活性降低,降低肝脏抗氧化损伤的能力,从而造成肝损伤[7]。ALT、AST主要分布在肝细胞内,当发生炎症损伤时,肝细胞肿胀破裂释放入血,因此血清生化指标能较灵敏地反映肝细胞损伤严重程度,是衡量机体肝功能的重要指标[8]。本研究建立CCl4致肝损伤模型,发现模型组小鼠血清中ALT、AST水平与正常对照组比较均明显升高。柴胡疏肝颗粒各剂量组能降低CCl4诱导肝损伤模型小鼠血清中ALT、AST水平。
ROS可与磷脂、酶、膜受体和核酸的多不饱和脂肪酸发生脂质过氧化反应,该反应改变细胞膜的流动性和渗透性,最终导致细胞结构和功能改变[9]。SOD是专一性抗氧化酶,为机体抗氧化应激的首道防线,通过与超氧自由基发生歧化反应,催化其转化为过氧化氢和氧气,从而清除体内的超氧阴离子。MDA是ROS诱导膜脂发生过氧化后的终产物,其与胞质、膜蛋白或酶形成聚合体而损害细胞膜结构,导致肝细胞变性、坏死[10]。因此,检测肝组织中SOD和MDA 的水平,可反映肝脏氧化损伤的程度。TNF-α、IL-6、IL-10均是肝损伤相关的重要炎性介质,加重肝细胞变性坏死的同时,促进炎症因子的释放,进而加剧炎症反应[11]。本研究表明,CCl4诱导小鼠肝损伤后肝组织中MDA、IL-6、TNF-α及ROS等炎症因子水平显著升高,SOD 水平显著降低,HE染色结果显示肝小叶汇管区附近肝细胞出现明显坏死,坏死区域可见大量炎性细胞浸润。而柴胡疏肝颗粒可下调Ccl2基因,逆转MCP-1等炎症因子上调,显著升高SOD水平,肝组织炎性细胞浸润和坏死程度明显减轻,提示其能缓解肝组织的炎症反应,改善肝组织损伤,对CCl4诱导肝损伤小鼠有一定保护作用。
氧化应激造成的生物分子损伤会破坏正常细胞生理学,影响脂类、碳水化合物等代谢过程。过氧化物酶体增殖物激活受体γ(peroxisome proliferator-activated receptor γ,PPARγ)是一种核激素受体,可调节葡萄糖和脂质的稳态以及激活Nrf2[12-13]。柴胡疏肝颗粒可能通过激活PPAR信号通路,上调下游靶基因,从而调节脂肪酸氧化等过程。本研究发现,柴胡疏肝颗粒能下调肝损伤后肝脏胆酸类和花生四烯酸代谢物19(S)-羟基二十碳四烯酸等,同时上调肝内糖原归于正常水平,逆转CCl4诱导肝损伤所致的糖代谢紊乱。
研究发现,Keap1-Nrf2-ARE信号通路是机体抗氧化应激或外源性损伤等的重要信号通路[14]。Keap1属于Kelch家族,是胞质肌动蛋白细胞骨架上的一种阻遏蛋白,可负性调节Nrf2[15]。Nrf2属于Cap-n-Collar调节蛋白家族,是细胞抗氧化应激的关键转录因子。通常Keap1与Nrf2结合在胞质内,为功能抑制状态;当细胞受到刺激,Nrf2即与Keap1解偶联进入细胞核,并结合到抗氧化反应元件(antioxidant response element,ARE)的DNA序列上,启动其调控的Ⅱ相解毒酶和抗氧化酶的基因进行表达,如HO-1、NQO1等,从而发挥机体抗氧化应激的作用[16]。HO-1是血红蛋白加氧酶的氧应激诱导型,当急性肝损伤时大量表达,发挥保护肝细胞的作用[10]。本研究发现柴胡疏肝颗粒能显著下调肝损伤后肝组织中的Keap1蛋白,上调Nrf2和HO-1蛋白,上调Nqo1基因,从而上调NQO1蛋白。
MAPK级联反应的3条信号转导通路激活后的生物学作用各不相同,研究表明细胞外调节蛋白激酶(extracellular regulated protein kinases,ERK)激活有助于肝细胞抗氧化应激,而JNK和p38 MAPK激活常表现为促凋亡,其中JNK信号通路是导致肝细胞坏死及凋亡的最主要途径。CCl4诱导产生的ROS和炎症因子的升高,可刺激p38 MAPK、JNK磷酸化而激活,激活后又可增加炎症因子的释放[17]。本研究发现柴胡疏肝颗粒能显著下调肝损伤后肝组织JNK、p38 MARK蛋白的表达。
综上所述,柴胡疏肝颗粒能显著降低CCl4诱导的肝损伤模型小鼠血清ALT、AST水平,显著升高肝损伤组织中SOD水平,降低MDA、IL-6、TNF-α及ROS水平,提升肝组织抗氧化应激作用,抑制炎症因子释放,缓解肝组织的炎性损伤;并能明显减少肝细胞坏死,减轻炎性细胞浸润,改善肝组织病理损伤,发挥一定的肝功能保护作用。柴胡疏肝颗粒能上调肝损伤后肝组织Nrf2、HO-1蛋白表达,下调Keap1、JNK、p38 MARK蛋白表达,提示柴胡疏肝颗粒可能通过激活Nrf2/HO-1信号通路缓解肝损伤模型小鼠的氧化应激损伤,抑制JNK/p38 MARK信号通路激活所致炎症反应和肝细胞坏死,从而发挥治疗作用,为临床应用柴胡疏肝颗粒治疗肝损伤提供了理论依据。
