ABSTRACT
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.
ABSTRACT
Objective:To discuss the clinical efficacy of modified Danshenyin and Erchentang in treating carotid atherosclerosis (CAS), and the effect on intimal injury. Method:Patients (151 cases) were divided into control group (75 cases) and observation group (76 cases). Specifically, 69 cases in control finished the treatment (4 cases fell off in follow-up, and 2 cases were eliminated), and 69 cases in observation group finished the treatment (3 cases fell off in follow-up, and 4 cases were eliminated). Patients in both group got atorvastatin calcium tablets, 10 mg/time, 1 time/day, and aspirin enteric-coated tablets, 100 mg/time, 1 time/day. Patients in control group got Hedan tablets, 2 tablets/time, 3 times/day. Patients in observation group got modified Danshenyin and Erchentang, 1 dose/day. The treatment lasted for 4 months. Before and after treatment, color Doppler ultrasound of carotid artery was detected, and carotid intima-media thickness (IMT), plaque number, plaque area, plaque thickness and hemodynamics were recorded. Levels of nitric oxide (NO), endothelin-1 (ET-1), von Willebrand factor (vWF), soluble intercellular adhesion molecule-1 (sICAM-1), vascular endothelial growth factor (VEGF), matrix metalloproteinase-9 (MMP-9), triglyceride (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), whole-blood low-shear viscosity (LBV), whole-blood high-shear viscosity (HBV), plasma viscosity (PV), platelet aggregation rate (PAR), fibrinogen (FIB), homocysteine (Hcy), interleukin-6 (IL-6), IL-10, tumor necrosis factor-<italic>α</italic> (TNF-<italic>α</italic>), serum superoxide dismutase (SOD), malondialdehyde (MDA), oxidized low density lipoprotein (ox LDL) and circulating glutathione peroxidase (GSH-Px) were detected before and after treatment. And the safety was evaluated. Result:After treatment, IMT, number, area and thickness of plaque in observation group were less than those in control group (<italic>P</italic><0.01). Peak systolic velocity and end diastolic velocity in observation group were higher than those in control group (<italic>P</italic><0.01), while pulsatility index and resistance index were lower than those in control group (<italic>P</italic><0.01). And levels of ET-1, vWF, sICAM-1, VEGF, MMP-9, TG, TC, LDL-C, LBV, HBV, PV, PAR, FIB, Hcy, IL-6, TNF-<italic>α</italic>, MDA and ox-LDL were lower than those in control group (<italic>P</italic><0.01), whereas levels of NO, HDL-C, IL-10, SOD and GSH-Px were higher than those in control group (<italic>P</italic><0.01). And there was no adverse reaction caused by traditional Chinese medicine. Conclusion:Modified Danshenyin and Erchentang can reduce plaque, improve hemodynamics and hemorheology, and regulate blood lipid metabolism and vascular endothelial factor, with anti-inflammatory and anti-oxidation damages. It can protect vascular intima, and inhibit the occurrence and development of CAS, with a safety in clinical use.
