OBJECTIVE To investigate the effects and mechanism of Danshen decoction influencing platelet physiological characteristics and function in hyperlipidemia model rats based on platelet membrane glycoprotein 4 (CD36)/phosphatidylinositol 3- kinase (PI3K)/protein kinase B (Akt) signaling pathway. METHODS The hyperlipidemia model rats were induced by feeding high- fat diet, and then randomly divided into model group, simvastatin group (0.004 g/kg), Danshen decoction high-dose and low-dose groups (3.6, 0.9 g/kg), and blank group (fed with basic feed), with 10 rats in each group. Rats in each administration group were intragastrically administered with corresponding drugs every day, and the other groups were intragastrically administered with equal volume of normal saline for 4 weeks. After the last administration, the contents of blood lipid biochemical indexes [total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C)], whole blood viscosity, plasma viscosity and fibrinogen (FIB)content in plasma, platelet-related parameters [platelet count (PLT), platelet distribution width (PDW) and mean plateletvolume (MPV)] were detected. The levels of plateletphysiological characteristics and function-related factors [von Willebrand factor (vWF), fibronectin (Fn), phospholipase A2(PLA2), thromboxane B2 (TXB2), 6-keto-prostaglandin F1α (6-keto-PGF1α), thromboxane A2 (TXA2), prostaglandin I2 (PGI2), cyclic adenosine monophosphate (cAMP), cyclic guanosine monophosphate (cGMP), β-thromboglobulin (β-TG)], platelet aggregation rate (maximum aggregation rate, 60 s aggregation rate, 180 s aggregation rate) and fibrinolytic system-related factors [tissue plasminogen activator (t-PA), plasminogen activator inhibitor 1 (PAI-1)] and the expressions of CD36/PI3K/Akt signaling pathway-related proteins [CD36, focal adhesion kinase (FAK), phosphatidylinositol 4-phosphate 5-kinase (PIP5K), PI3K, phosphorylated Akt (p-Akt), p-Akt1/2/3] in platelet were all determined. RESULTS Compared with blank group, the contents of TC, TG and LDL-C in plasma, whole blood viscosity, plasma viscosity, the plasma levels of FIB, PLT, MPV, vWF, Fn, PLA2, TXB2, TXA2, cGMP and β-TG, maximum platelet aggregation rate, 60 s aggregation rate, the expressions of PAI-1 in plasma, protein expressions of CD36, FAK, PIP5K, PI3K, p-Akt and p-Akt1/2/3 were significantly increased in the model group (P<0.05). The content of HDL-C and the levels of 6-keto-PGF1α, PGI2 and t-PA were significantly decreased (P<0.05). After the intervention of Danshen decoction, most of the above indexes were significantly reversed (P<0.05). CONCLUSIONS Danshen decoction can improve the physiological characteristics and function of platelets in hyperlipidemia model rats, and its mechanism may be related to the down-regulation of CD36/PI3K/Akt signaling pathway activity and the reduction of platelet activation.

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.
