力的影响,以及对正常小鼠血清肝、肾功能指标和肝、肺等组织病理形态学的影响,评价其安全性。构建脂多糖(1 μg/mL)诱导的
RAW264.7 细胞炎症模型,考察 10、20 μg/mL Eh-ENVs 对模型细胞中炎症因子 mRNA 表达和活性氧(ROS)水平的影响,并考察
RAW264.7 细胞对 Eh-ENVs 的摄取效率。构建 APAP 诱导的肝损伤小鼠模型,考察 4 mg/kg Eh-ENVs 对模型小鼠血清肝功能指

路相关 mRNA 及其蛋白表达的影响。结果 体外实验结果显示,Eh-ENVs 对 RAW264.7 和 AML12 细胞均无增殖抑制作用;Eh-
ENVs可被RAW264.7细胞高效摄取,并能显著降低细胞中白细胞介素1β(IL-1β)、肿瘤坏死因子α(TNF-α)mRNA表达和ROS水

(ALT)、天冬氨酸氨基转移酶(AST)水平(P<0.05),上调/升高肝组织中IL-10 mRNA以及Nrf2、HO-1、NQO1 mRNA及其蛋白表

ABSTRACT OBJECTIVE To investigate the ameliorative effect and mechanism of Euphorbia hirta L. -derived exosome-like
nanovesicles(Eh-ENVs) on acetaminophen (APAP)-induced liver injury based on the nuclear factor erythroid 2 related factor 2
(Nrf2)/heme oxygenase-1 (HO-1)/NAD(P)H:quinone oxidoreductase 1 (NQO1) pathway. METHODS The safety of Eh-ENVs
was evaluated by examining their effects on the viability of RAW264.7 and AML12 cells, as well as serum liver and kidney
function indicators and histopathology of liver, lung, and other tissues in normal mice. A lipopolysaccharide (1 μg/mL)-induced
RAW264.7 cell inflammation model was constructed to investigate the effects of 10 and 20 μg/mL Eh-ENVs on the mRNA
expression of inflammatory factors and reactive oxygen species (ROS) level in model cells, and the uptake efficiency of Eh-ENVs
by RAW264.7 cells was also examined. An APAP-induced liver injury mouse model was established to investigate the effects of 4
mg/kg Eh-ENVs on serum liver function indicators, liver histopathology, mRNA expression of inflammatory factors,
malondialdehyde (MDA) level, superoxide dismutase (SOD) level, and mRNA and protein expressions related to the Nrf2/HO-1/
NQO1 pathway in liver tissue of model mice. RESULTS In vitro results showed that Eh-ENVs had no inhibitory effect on the
proliferation of RAW264.7 and AML12 cells;Eh-ENVs could
