OBJECTIVE To investigate the effects and mechanisms of Buyang huanwu decoction （BYHWD） and its active fractions in ameliorating non-alcoholic fatty liver disease. METHODS BYHWD and its effective fractions obtained through ethanol precipitation， as well as 30% ethanol， 50% ethanol， and 75% ethanol fractions （namely， the CC effective fraction， 30YC effective fraction， 50YC effective fraction， and 75YC effective fraction）， were prepared. These preparations were administered to rats via intragastric administration to prepare corresponding drug-containing serum （blank serum and simvastatin-containing serum were prepared using the same protocol）. Human L02 hepatocytes were divided into control group， model group， simvastatin-containing serum group， BYHWD-containing serum group， CC-containing serum group， 30YC-containing serum group， 50YC-containing serum group， and 75YC-containing serum group. Except for the control group， other groups were given 0.2 mol/L oleic acid for 24 h to induce a lipid accumulation model， and then intervened with 20% drug-containing serum/blank serum for 24 h. The lipid deposition in cells was observed， and the proportion of lipid droplet area was calculated； the levels of triglycerides （TG） and indicators of oxidative stress [malondialdehyde （MDA）， superoxide dismutase （SOD）] as well as liver function [alanine amino- transferase （ALT）， aspartate amino-transferase （AST）] in cells were detected； protein and mRNA expressions of AMP-activated protein kinase （AMPK）/sterol regulatory element-binding protein-1 （SREBP-1）/glycerol-3-phosphate acyltransferase （GPAT） signaling pathway were also measured. RESULTS Compared with the control group， cells in the model group exhibited severe cellular steatosis， with a significantly increased proportion of lipid droplet area， as well as the elevated levels of TG， ALT， AST， and MDA in cells， along with significantly up-regulated mRNA and protein expression levels of SREBP-1 and GPAT （P＜0.05）. The level of SOD， mRNA expression of AMPK， as well as the protein phosphorylation level of AMPK were decreased significantly （P＜0.05）. Compared with the model group， cellular steatosis was alleviated in all drug-containing serum groups， and the levels of most of the aforementioned quantitative indicators were significantly reversed （P＜0.05）. CONCLUSIONS BYHWD and its active fractions can exert a therapeutic effect on improving non-alcoholic fatty liver disease by regulating the AMPK/SREBP-1/GPAT signaling pathway， inhibiting oxidative stress responses， and reducing lipid deposition.

OBJECTIVE To explore the regulatory mechanism of Danshen decoction on dyslipidemia in hyperlipidemia model rats. METHODS The experimental rats were divided into blank group （n＝9， no modeling）， model group （n＝8， modeling）， and Danshen decoction group （n＝9， modeling）. Starting from the 9th week of feeding with the high-fat diet， rats in the Danshen decoction group were given the corresponding medication solution （3.6 g/kg） intragastrically， while blank group and model group were given equal volume of normal saline， once a day， for 4 consecutive weeks. After 4 weeks of administration， the plasma levels of triglycerides （TG）， total cholesterol （TC）， low-density lipoprotein cholesterol （LDL-C）， and high-density lipoprotein cholesterol （HDL-C） were measured in each group of rats； the pathological and morphological changes of liver tissue were observed； the differential proteins between samples were screened out by TMT quantitative proteomic analysis； the expression levels of the key differentially expressed proteins in the liver， including epoxide hydrolase 2 （EPHX2）， perilipin 2 （PLIN2）， peroxisome proliferator activated receptor γ （PPAR γ） and glycogen synthase kinase-3β （GSK-3β）were detected. RESULTS Compared with the model group， the plasma levels of TC， TG and LDL-C in the Danshen decoction group were significantly reduced （P＜0.05）， while the level of HDL-C was significantly increased （P＜0.05）. The liver tissue of rats inmodel group showed uneven staining， disordered arrangement of liver plates， disappearance of liver sinusoids， nuclearcondensation or disappearance of some cells， swelling and fusion of cytoplasm， proliferation of connective tissue， and diffuse vacuolar-like fat droplet changes. The liver tissue of Danshen decoction group showed varying degrees of improvement in the above pathological and morphological. The results of differential protein analysis showed that the total number of differential proteins was 298 between the model group and the blank group； the total number of differential proteins was 139 between the model group and Danshen decoction group. Compared with the model group， the expression levels of EPHX2 and PLIN2 proteins in the liver tissue of rats in the Danshen decoction group were significantly reduced （P＜0.01）， while the expression levels of GSK-3β and PPARγ were significantly increased （P＜0.01）. CONCLUSIONS Danshen decoction has a significant improvement effect on the plasma lipid levels and the pathological and morphological of the liver tissue in hyperlipidemia model rats. Its regulatory mechanism may be related to the up-regulation of PPARγ and GSK-3β expression and down-regulation of EPHX2 and PLIN2 expression， and the signaling pathways involved may include PPAR-γ signal pathway.

ObjectiveTo decipher the mechanism of Danshenyin in regulating platelet activation in the rat model of hyperlipidemia by means of proteomics and molecular biology. MethodWistar rats were randomized into blank， model， and Danshenyin groups （n=10） according to the blood lipid level. The rats in the blank group were fed with a basic diet， and those in the model and Danshenyin groups with a high-fat diet. All the rats had free access to water and food. The treatment began at the 9th week. The rats in the Danshenyin group were administrated with Danshenyin by gavage at a crude drug dose of 3.6 g·kg^-1. The rats in the model and blank groups were administrated with an equal volume of normal saline according to body weight. At the 12th week， the tissue samples were collected for the measurement of related indicators， and the blood lipid level was measured by an automatic biochemical analyzer. The whole blood viscosity and plasma viscosity were measured by an automatic hemorheometer. The platelet proteome was determined by liquid chromatography-mass spectrometry. Western blotting was employed to determine the protein levels of platelet membrane glycoprotein 4 （CD36）， focal adhesion kinase （FAK）， phosphatidylinositol 4-phosphate 5-kinase （PIP5K）， phosphorylated phosphatidylinositol 3-kinase （p-PI3K）， protein kinase B （Akt）， and phosphorylated protein kinase B （p-Akt）. ResultCompared with the model group， Danshenyin lowered the levels of total cholesterol （TC）， triglyceride （TG）， and low-density lipoprotein cholesterol （LDL-C） in the plasma （P<0.05）， elevated the level of high-density lipoprotein cholesterol （HDL-C） （P<0.05）， and reduced the platelet aggregation rate （P<0.05）. Compared with the blank group， the modeling up-regulated the expression of 44 proteins and down-regulated the expression of 12 proteins. Compared with the model group， Danshenyin up-regulated the expression of 21 proteins and down-regulated the expression of 22 proteins. Compared with the blank group， Danshenyin up-regulated the expression of 31 proteins and down-regulated the expression of 49 proteins. The gene ontology （GO） functional enrichment showed that the differentially expressed proteins were mainly involved in cholesterol transport and efflux， production of cytokines， dyslipidemia， and platelet activation. The Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment showed that the differentially expressed proteins were mainly involved in ECM-receptor interaction， peroxisome proliferators-activated receptors （PPAR）， focal adhesion， and PI3K/Akt signaling pathways. Danshenyin can significantly down-regulate the expression of CD36， FAK， PIP5K， PI3K， p-Akt （Ser473）， and p-Akt1/2/3 （Thr308）. ConclusionDanshenyin can restore the blood lipid level of hyperlipidemia rats and inhibit the platelet activation caused by abnormal lipid levels by down-regulating the CD36/PI3K/Akt signal cascade.
