摘 要 目的 基于血清代谢组学研究柴胡皂苷C(SSC)对四氯化碳(CCl4 )诱导的急性肝损伤(ALI)小鼠的保护作用及机制。方
法 将 40 只小鼠按随机数字表法分为空白组(水)、模型组(水)、阳性对照药组(联苯双酯滴丸,150 mg/kg)和 SSC 低、高剂量组
(2.5、10 mg/kg),每组8只,每天灌胃水/药物1次,连续7 d。末次给药1 h后,除空白组外的其余各组小鼠均腹腔注射0.2%CCl4橄
榄油溶液以建立ALI模型。造模17 h后,计算小鼠肝指数,检测小鼠血清中天冬氨酸转氨酶(AST)、丙氨酸转氨酶(ALT)、乳酸脱
氢酶(LDH)、肿瘤坏死因子α(TNF-α)、白细胞介素6(IL-6)、IL-1β水平,观察小鼠肝组织病理学变化,并采用液质联用法对小鼠血
清进行代谢组学分析。结果 与空白组比较,模型组小鼠肝指数和 ALT、AST、LDH、TNF-α、IL-6、IL-1β 水平均显著升高(P<
0.01);肝细胞出现水肿、空泡变性并有较多坏死,可见炎症细胞大量浸润。与模型组比较,SSC高剂量组小鼠肝指数和血清指标
水平均显著降低(P<0.05或P<0.01),且肝组织病理学损伤明显改善。代谢组学研究结果显示,与模型组比较,SSC高剂量组小
鼠血清中上调的差异代谢物有63个、下调的有256个(包括前列腺素B2、20-羟基白三烯B4、5-羟色氨酸、7α-羟基胆固醇等代谢物),
主要涉及花生四烯酸代谢、5-羟色胺突触、初级胆汁酸生物合成等代谢途径。结论 高剂量SSC可通过下调前列腺素B2、20-羟基
白三烯B4等关键代谢物水平,减少花生四烯酸代谢、5-羟色胺突触、初级胆汁酸生物合成等代谢途径,进而对CCl4诱导的ALI小鼠
发挥保护作用。

ABSTRACT OBJECTIVE To investigate the protective effect and mechanism of saikosaponin C (SSC) on acute liver injury
(ALI) in mice induced by carbon tetrachloride (CCl4 ) based on serum metabolomics. METHODS Forty mice were divided into
blank group (water), model group (water), positive control drug group (Biphenyl diester drop pills, 150 mg/kg), and SSC low-
and high-dose groups (2.5, 10 mg/kg) using the random number table method, with 8 mice in each group. They were given water/
relevant drugs, once a day, for 7 consecutive days. One hour after the last administration, all mice were intraperitoneally injected
with 0.2% CCl4 olive oil to induce ALI model, except for the blank group. After 17 hours of the modeling, the liver index of mice
was calculated. The levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase (LDH),
tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and IL-1β in serum of mice were detected. The histopathological changes
of liver tissue were observed. Meanwhile, the serum metabolomics of mice were analyzed by liquid chromatography-mass
spectrometry. RESULTS Compared with the blank group, the levels of liver index, ALT, AST, LDH, TNF-α, IL-6, and IL-1β in
the model group were significantly increased (P<0.01). Hepatocytes were edema, vacuolar degeneration, more necrosis, and a
large number of inflammatory cells were infiltrated. Compared with the model group, liver index and serum index levels of mice
were significantly decreased (P<0.05 or P<0.01), accompanied by marked improvement in histopathological damage to the liver
tissue. The metabolomics results showed that compared with the model group, there were 63 up-regulated and 256 down-regulated
differential metabolites in the serum of mice in the SSC high-dose group, including prostaglandin B2, 20-hydroxy-leukotriene B4, 5-
hydroxy-L-tryptophan, 7α -hydroxycholesterol, etc.; these
