OBJECTIVE:
To investigate the effects of exendin-4 on hepatic lipid metabolism, fibrosis and oxidative stress in mice with streptozotocin (STZ)-induced diabetes and explore the underlying mechanisms.
METHODS:
C57BL/6J mice were fed with high-fat diet (HFD) for 4 weeks and received intraperitoneal injections of 120 mg/kg STZ to induce diabetes. After successful modeling, the mice were randomized into diabetic control group and exendin-4 treatment group (DM+E4), and in the latter group, the mice were given a daily dose of 1 nmol/kg of exendin-4 for 8 weeks. The changes in the body weight (BW) and random blood glucose (RBG) in the mice were recorded. The mRNA expressions of the genes related with liver lipid metabolism, fibrosis and oxidative stress were analyzed using RT-PCR, and the structural changes of the liver tissues were observed with HE, Sirius red and oil red O staining; the expressions of TGF-β1, Nrf2 and HO-1 proteins in the liver tissues were detected using Western blotting.
RESULTS:
The diabetic mice showed significantly higher RBG levels and BW with obvious lipid deposition, fibrosis and oxidative stress in the liver as compared with the normal control mice ( < 0.001). Exendin-4 treatment of the diabetic mice did not significantly lessened liver lipid deposition but obviously reduced the levels of RBG and TG ( < 0.05), lowered the expression levels of liver fibrosis-related genes TGF-β, -SMA and Col-Ⅰ ( < 0.05), increased the expression levels of the antioxidant genes Nrf2, HO-1 and GPX4 ( < 0.01), and enhanced the protein expressions of Nrf2 and HO-1 in the liver tissues ( < 0.01).
CONCLUSIONS
Exendin-4 improves liver fibrosis and oxidative stress in diabetic mice by activating Nrf2/HO-1 pathway without significantly reducing liver lipid deposition.

OBJECTIVETo compare the toxicity on normal liver cells LO2 before and after Kansui Radix stir-baked with vinegar, and make a preliminary study on the mechanism of detoxication of Kansui Radix stir-baked with vinegar.
METHODThe MTT method was adopted to detect the cell activity, with normal liver cells LO2 as the study object. The morphology of cells were observed, and the level or content of AST, ALT, LDH, SOD, Na+-K+-ATPase, Ca2+-Mg2+ -ATPase, GSH and MDA were determined in cell culture supernatant and splitting supernatant.
RESULTCompared with the control group, Kansui can obviously inhibit the cell activity (P < 0.01) and morphology, and increase the levels of ALT, AST, and LDH (P < 0.01) in the supernatant fluid of cell incubation, and decrease the level of SOD and the content of GSH (P < 0.01). Besides, it significantly increased the content of MDA (P < 0.01) and significantly decreased the level of Na+-K+-ATPase and Ca2+-Mg2+ -ATPase (P < 0.01) in the supernatant fluid of cell dissociation. Compared with Kansui group of various doses, Kansui Radix stir-baked with vinegar can significantly decrease the cell proliferation inhibition and the trend of morphological variation, and obviously decrease the levels of ALT, AST, and LDH (P < 0.01) in the supernatant fluid of cell incubation, and significantly increase the level of SOD and the content of GSH (P < 0.01), and significantly decrease the content of MDA (P < 0.01). Additionally, it significantly increased the level of Na+-K+-ATPase and Ca2+-Mg2+ ATPase (P < 0.01) in the supernatant fluid of cell dissociation, and showed a certain dose-effect relationship.
CONCLUSIONStir-baking with rice vinegar can release the hepatotoxicity of Kansui Radix. Its possible mechanism was that Kansui Radix stir-baked with vinegar can decrease the influence of Kansui Radix on the permeability of liver cells LO2 membrane and oxidative damage, in order to provide basis for further exploration of the detoxication mechanism of Kansui Radix stir-baked with vinegar.
