复方丹参滴丸降低尿酸和内皮保护作用动物实验研究

Role of compound red sage root dripping pill in reducing uric acid (UA) and protecting endothelium: An animal experimental study

  • 摘要: 目的 探讨复方丹参滴丸对高尿酸血症(hyperuricemia,HUA)动物模型血尿酸(uricacid,UA)的降低作用及对血管内皮的保护作用,为临床降UA治疗提供新途径。 方法 38只SPF级雄性昆明小鼠,按体质量随机分为3组:对照组(A)12只(酵母膏+乙胺丁醇+蒸馏水灌胃);别嘌呤醇组(B)13只(酵母膏+乙胺丁醇+别嘌呤醇灌胃);复方丹参滴丸组(C)13只(酵母膏+乙胺丁醇+复方丹参滴丸灌胃)。3周后测定各组血清UA和一氧化氮(NO)水平;分离胸腹主动脉,石蜡包埋、切片后HE染色,并进行免疫组化检测核转录因子-κB(NF-κB)和血管内皮细胞黏附因子-1(VCAM-1)的蛋白表达。 结果 别嘌呤醇组和丹参滴丸组血清UA水平(372.71±22.16) μmol/L和(328.65±28.78) μmol/L)与对照组(605.67±54.76) μmol/L相比均有显著下降(P< 0.01),血清NO水平(29.55±1.55) μmol/L和35.11±2.03 μmol/L)与对照组(20.89±1.70) μmol/L)相比均升高(P< 0.01),复方丹参滴丸组优于别嘌呤醇组(P< 0.01)。对照组主动脉内膜NF-κB和VCAM-1可见连续阳性表达,其余两组表达不同程度减弱。各组主动脉内膜形态和血管壁结构均未发生改变。 结论 复方丹参滴丸可降低HUA小鼠血清UA水平,提升血清NO水平,效果均优于别嘌呤醇;同时可抑制HUA小鼠主动脉内膜NF-κB和VCAM-1的表达。

     

    Abstract: Objective To provide a new therapy for reducing uric acid (UA) by studying the role of compound red sage root dripping pill in reducing UA and in protecting endothelium in a hyperuricemia animal model. Methods Thirty-eight SPF-class male Kunming mice were randomly divided into control group (group A, n=12), allopurinol treatment group (group B, n=13), and compound red sage root dripping pill treatment group (group C, n=13). Three weeks after the animals in 3 groups were treated with yeast + ethambutol + distilled water gastric lavage, allopurinol + ethambutol + allopurinol gastric lavage, and yeast + ethambutol+ compound red sage root dripping pill gastric lavage, respectively, their serum UA and NO levels were measured. Thoracicoabdominal aorta was isolated and cut into sections which were stained with H& E. Expressions of NF-κB and VCAM-1 were detected with immunohistochemical staining. Results The serum UA level was significantly lower whereas the serum No level was significantly higher in groups B and C than in group A (372.71±22.16) μmol/L and (328.65±28.78) μmol/L vs (605.67±54.76) μmol/L, P < 0.01; (29.55±1.55) μmol/L and (35.11±2.03) μmol/L vs (20.89±1.70) μmol/L, P< 0.01). The NF-κB and VCAM-1 were strongly expressed in aorta endomembrane of group A but weakly expressed in groups B and C. No significant change occurred in aorta endomembrane morphology and blood vessel wall structure of 3 groups. Conclusion compound red sage root dripping pill can reduce the serum UA level, down-regulate the expression of NF-κB and VCAM-1, and increase the serum NO level in hyperuricemia mice.
