C57 BL/6 J mice at the same age and background strain were included in the Control group. Western blot and immunohistochemistry were used to measure ABCA1, PCSK9, TLR4, and NF-κB protein expression in mouse aortas. Enzyme-linked immuno sorbent assay was used to measure mouse serum tumor necrosis factor-α(TNF-α), interleukin-10(IL-10), monocyte chemoattractant protein 1(MCP-1), and intercellular cell adhesion molecule-1(ICAM-1) expression. Serum lipid profiles and histopathology were also assessed. Shoushen granule were composed of Heshouwu(Radix Polygoni Multiflori) 15 g, Gouqizi(Fructus Lycii) 15 g, Sheng shanzha(Raw Fructus Crataegus Pinnatifidae) 10 g, and Sanqi(Radix Notoginseng) 3 g.RESULTS: ApoE-/-mice fed with a high-fat diet had notable AS lesions, with reduced ABCA1 and IL-10 levels, elevated PCSK9, TLR4, NF-κB, TNF-α, MCP-1,and ICAM-1 expression, and increased total cholesterol(TC) and low density lipoprotein cholesterol(LDL-C) contents. With drug interventions, the areas of AS plaques were significantly reduced,the ABCA1 and IL-10 levels were increase, while the PCSK9, TLR4, NF-κB, TC, and LDL-C contents,and the TNF-α, MCP-1, and ICAM-1 expression were reduced.CONCLUSION: Shoushen granule effectively interfered with AS development by antagonizing the expression of key factors of the PCSK9 and TLR4/NF-κB signaling pathway to upregulate ABCA1 expression.展开更多

Brachial-ankle pulse wave velocity(ba PWV) and Ankle-Brachial Pressure Index(ABI)were measured by automated arteriosclerosis detector. The changes of common carotid artery intima-media thickness(IMT) and parameters of the carotid artery elasticity in patients,including stiffness parameter(β),pressure-strain elastic modulus(Ep),arterial compliance(Ac),augmentation index(AI),and pulse wave velocity β(PWVβ) were detected by Echo-Tracking(ET) technique before and after 24 week treatment. In the meantime,levels of blood lipid,and liver and renal function were measured respectively.RESULTS: After 24 weeks,ba PWV,IMT and parameters of the carotid artery elasticity(β,Ep,AI and PWVβ) were markedly decreased in intervention group compared with those of before treatment(P < 0.01),but the level of Ac was increased significantly(P < 0.01). And there were no significant differences compared with control group on the same period(P > 0.05).CONCLUSION: In this pilot study,it was demonstrated ET technology and automated arteriosclerosis detector could be used to evaluate carotid artery elasticity effectively,and the action of Shoushen granule on carotid atherosclerosis might be related to the regulation of carotid artery elasticity.展开更多

[Methods] According to relevant methods specified in Appendix to 2010 Chinese Pharmacopoeia,the water content,total ash,and extracts of Shoushen and Naishoushen were detected,and thin layer chromatography( TLC) was applied to make qualitative identification. Gastrodin was used as the reference substance,extracted with 70% methanol,and then sprayed with ethyl acetate-formic acid-water( 9∶ 1∶ 0. 2) as the developing solvent,and then sprayed with 10% phosphomolybdic acid ethanol solution and heated at 105℃ to clear spot color. UV-Visible spectrophotometry and high performance liquid chromatography( HPLC) were used to analyze the content of polysaccharides and gastrodins in Shoushen and Naishoushen. The chromatographic column was a ZOBB AX eclipse XDB-C_(18)( 4. 6 mm × 250 mm,5 cm) column with the methanol-0. 04% phosphoric acid solution( 8∶92) as the mobile phase,the flow rate of 1. 0mL/min,the detection wavelength of 222 nm,and the column temperature of 30℃.[Results]In the thin-layer chromatography test,spots of the same color appeared at the positions corresponding to the chromatogram of the reference substance. Gastrodin eluted under high pressure reached baseline separation. Gastrodin had a good linearity in the concentration range of 0. 009-0. 09 mg/m L. The regression equation was Y = 586 866 X + 425 821( R^2= 0. 999 6),and the average recovery rate was100. 1%. Precision test,reproducibility test,and stability test conformed to the requirements. The results of extracts of three batches of samples were 26. 13%-42. 58%,water content was 3. 47%-5. 31%,and total ash was 5. 43%-6. 33%. [Conclusions] The quality control method has high reliability,high sensitivity,high specificity,high accuracy,and high stability. The results are expected to provide a scientific basis for the identification,resource utilization,and improvement of quality standard for Shoushen and Naishoushen.展开更多
