This paper surveys the epidemiological studies of hyperuricemia and CHD and summarizes the clinical study discussing the association between hyperuricemia and coronary heart disease with a prospect of exploring the possible mechanisms of compound Danshen dripping pills in reducing SUA in patients with coronary heart disease.展开更多

Methods： Thirty-two rats were randomly divided into four groups： the blank control group treated with distilled water, the positive control group treated with simvastatin （1.8 mg/kg）, the test group I treated with Chinese herbal compound of XS （0.135 g/kg）, and the test group 1T treated with Chinese herbal compound of XS （0.135 g/kg） and HL （0.135 g/kg）. All the treatments were administered for 7 successive days by gastrogavage. Rats＇ blood serum was harvested 1 h after the last administration to prepare respective drug- containing serum. HUVECs were exposed to ox-LDL （100 μg/mL） to induce cell injury model and incubated with corresponding drug-containing serum for 24 h. Untreated HUVECs were set for blank control. Levels of interleukin-6 （IL-6）, tumor necrosis factor-α （TNF-α）, and soluble intercellular adhesion molecule-1 （slCAM-1） in supematant of cultured HUVECs were determined by enzyme-linked immunosorbent assay （ELISA）. HUVEC surface expressions of ICAM-1 and E-selectin were determined by flow cytometry. Results： Levels of IL-6, TNF-α, and sICAM-1 in the supernatant of HUVECs as well as the cell surface expressions of ICAM-1 and E-selectin significantly increased after 24-h ox-LDL stimulation （P〈0.01）, while the abnormal elevations, except slCAM-1 in the test group Ⅰ, were all reduced in the treated groups （the positive control and the two test groups） significantly （P〈0.01 or P〈0.05）. Besides, the effect in the test group Ⅱ seemed somewhat higher than that in the test group Ⅰ but with no statistical significance （P〉0.05）. Conclusion： Drug-containing serum of XS plus HL has a certain inhibitory effect on the vascular endothelial inflammation response induced by ox-LDL.展开更多

MTT assay wasused to evaluated H9C2 cells viability. H9C2 cells were divided into normal control group, triptolide group, lipopolysaccharide(LPS) group, drug-containing serum group and mi RNA-21 inhibitor group. micro RNA-21(mi RNA-21) inhibitor was structured and transfected into H9C2 cells. Western blot and immunofluorescence assay were applied to examine toll-like receptor 4(TLR4), phosphorylated p-38(p-p38) and p-p65 expression. Quantitative real-time PCR(q RT-PCR) was used to evaluated m RNA levels of mi RNA-21. Enzyme linked immunosorbent(ELISA) was used to measure tumor necrosis factor α(TNF-α), IL-6 and IL-17 levels.RESULTS: Drug-containing serum treatment significantly increased cell viability compared to LPS treated group. q RT-PCR results indicated that mi RNA-21 levels were significantly decreased in drugcontaining serum group compared to LPS group.Early and late apoptosis in drug-containing serum group were significantly decreased compared to LPS group. Western blot and immunofluorescence assay results showed that TLR4, p-p38 and p-p65 levels in drug-containing serum group were significantly decreased compared to LPS group. ELISA findings indicated that drug-containing serum significantly decreased inflammatory cytokine levels of TNF-α, IL-6 and IL-17.CONCLUSION: Drug-containing serum of Xinfeng capsules protect against lipopolysaccharide instructed H9C2 cells from death by enhancing mi RNA-21 and inhibiting TLR4/p-p38/p-p65 signaling pathway and proinflammatory cytokines expression.展开更多
