Abstract:
Objective To investigate the protective effect of Xuebijing combined with nuclear factor E2-related factor 2(Nrf2)activator on lipopolysaccharide(LPS)-induced hepatocyte injury.Methods Human normal liver cells L-02 were randomly divided into control group(normal culture),LPS group(40 μg·mL-1 LPS),Xuebijing group(25 times diluted Xuebijing),inhibitor group(40 μg·mL-1 LPS+5 μg·mL-1 Nrf2 inhibitor ML385),activator group(40 μg·mL-1 LPS+15 μg·mL-1 Nrf2 activator sulforaphane),Xuebijing+activator group(40 μg·mL-1 LPS+25 times diluted Xuebijing+15 pg·mL-1 Nrf2 activator sulforaphane).After treatment for 24 h,the expression of nuclear Nrf2 was detected by Western blot assay;cell proliferation was detected by 5-ethynyl-2'-deoxyuridine(Edu)assay;cell apoptosis was detected by flow cytometry;reactive oxygen species(ROS)levels were detected by fluorescent probe.Results The nuclear Nrf2 protein levels of control group,LPS group,Xuebijing group,inhibitor group,activator group and Xuebijing+activator group were 0.83±0.08,0.40±0.04,0.59±0.07,0.26±0.04,0.90±0.10,1.24±0.13,respectively;the Edu positive cell rates were(42.99±4.37)％,(16.30±1.42)％,(30.08±2.10)％,(14.67±1.27)％,(28.66±2.54)％,(38.31±2.54)％,respectively;the apoptosis rates were(4.39±0.42)％,(25.17±3.70)％,(14.44±0.99)％,(28.14±1.26)％,(17.99±1.30)％,(10.50±0.86)％,respectively;the mean density values of ROS were 1.00±0.04,3.48±0.34,1.88±0.15,4.25±0.37,1.87±0.19,1.26±0.12,respectively.The above indexes of LPS group were significantly different from those of control group(all P＜0.05);the above indexes of Xuebijing group,inhibitor group and activator group were compared with LPS group,respectively,and the differences were statistically significant(all P＜0.05);the above indexes of Xuebijing+agonist group were compared with Xuebijing group or agonist group,respectively,and the differences were statistically significant(all P＜0.05).Conclusion Xuebijing combined with Nrf2 activator can reduce LPS-induced hepatocyte injury by enhancing antioxidant system,and the combined treatment effect is better than Xuebijing alone.
