    Abstract:
    OBJECTIVE: To study the effects of Fuzheng Huayu Decoction on plasma proteome in cirrhosis. METHODS: Twenty-six male S-D rats were randomly divided into three groups, cirrhotic model group (n = 10), treated with CCl4 (CCl4/olive oil: v/v = 1:1), Fuzheng Huayu Decoction intervention group (n = 10), treated with CCl4 + Fuzheng Huayu Decoction, and normal control group (n = 6), treated with olive oil only. After 8 weeks, blood sample was collected from the vena cava inferior to undergo bi-dimensional electrophoresis (2DE) and analysis by PDQuest 7.3 software. Differential protein spots were cut, enzyme hydrolysis was conducted, and peptide fragments extracted from the mixture underwent mass spectrometry with MALDI-TOF-TOF-MS. The liver fibrogenesis was assessed by digital image analysis instrument of Masson's trichrome stained sections. RESULTS: The fibrosis area of the Fuzheng Huayu Decoction was 9% +/- 4%, significantly smaller than that of the cirrhotic model group (12% +/- 5%, P < 0.05). Ten markedly changed protein spots were identified by MALDI-TOF-TOF-MS. Eight of the 10 proteins, including plasma glutathione peroxidase, plasma glutathione peroxidase precursor, prealbumin, haptoglobin, apolipoprotein A-IV precursor, complement C4, inter-alpha-inhibitor H4 heavy chain, and serine/threonine-protein kinase MARK1 (microtubule- affinity regulating kinase 1) were expressed very lowly in the cirrhotic model group while were expressed highly in the Fuzheng Huayu Decoction group. The expression of liver regeneration-related protein LRRG03 and vimentin increased in the cirrhotic model group, and reduced in the Fuzheng Huayu Decoction group. CONCLUSION: Some proteins related to oxidative stress, cell proliferation and transformation have changed in the plasma of cirrhosis induced by CCl4. Fuzheng Huayu Decoction promotes protein synthesis and plays an anti-fibrotic role by antioxidation and accommodation of cell proliferation and transformation.
