摘要
The aim of this paper is to study the effects of Fuzheng Huayu Decoction on the plasma proteome in cirrhotic rats.Twenty-six male Sprague-Dawley(SD)rats were randomly divided into three groups:cirrhotic model group(n510),treated with CCl_(4)(CCl_(4)/olive oil:v/v51:1);Fuzheng Huayu Decoction intervention group(n510),treated with CCl_(4)+Fuzheng Huayu Decoction;and normal control group(n56),treated with olive oil only.After 8 weeks,blood samples were collected from the inferior vena cava 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(MS)with MALDI-TOF-TOF-MS.The liver fibrogenesis was assessed using a digital image analysis instrument of Masson’s trichrome stained sections.The fibrosis area of the Fuzheng Huayu Decoction was(8.9±3.7)%,significantly smaller than that of the cirrhotic model group[(12.4±4.7)%,P<0.05].Ten markedly changed protein spots were identified by MALDI-TOFTOF-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 microtubuleaffinity regulating kinase 1(MARK1)were expressed very lowly in the cirrhotic model group while they 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 FuzhengHuayu Decoction group.Some proteins related to oxidative stress,cell proliferation and transformation have changed in the plasma of cirrhosis induced by CCl_(4).Fuzheng Huayu Decoction promotes protein synthesis and plays an anti-fibrotic role by antioxidation and accommodation of cell proliferation and transformation.
