【摘要】 目的:系统回顾中西医防治高血压病的理论与进展,通过临床与实验研究探讨血压平治疗高血压病的作用机制。方法:观察该药对二肾一夹型高血压大鼠模型的血压、血浆肾素活性(PRA)、血管紧张素2(AngII)、一氧化氮(NO)/内皮素(ET)及左室肥厚、血管形态学的影响。观察该药对高血压病患者血压、症状证候积分、植物神经功能、血液流变学、微循环及前列环素(PGI2)/血栓素(TXA2)的影响。结果:实验发现:血压平在降压的同时能改善心室肥厚与血管形态改变,降低PRA、AngII,升高NO、降低ET、恢复NO/ET比值。临床观察发现:血压平能改善植物神经功能、血液流变性和微循环,升高PGI2、降低TXA2,有很好的临床疗效而无明显毒副作用。结论:血压平具有降压、逆转心血管重构、有效保护靶器官等作用。其机理可能与拮抗RAS系统、调整植物神经功能、改善微循环与血液流变性、保护血管内皮细胞等有关。结合前期研究认为本药具有进一步研发的价值。

【Abstract】 Object:The paper reviews the theories and advancement of prevention and treatment of essential hypertension(EH) by modern medicine and TCM.We attempted to assess trie mechanism of treatment of EH with Xueyaping nose drop. Method:l.To study the effect of Xueyaping on the two kidney ne clip renal hypertensive rat (2K c RHR), including blood pressure(BP),plasma renin aetivity(PRA),angiotensin II(AngIJ),nitric oxide(NO)/endothelin(ET) and left ventri 梒ular hypertrophy(LVH).2.to observe BP,symptoms and syndrorn index points, the function of autonomic nervous system,hemorheology,microcirculation and PGI2/TXA2 of EH patients with Xueyaping.Result:The experimental and clinical research showed that Xueyaping can overthrow the cardiovascular remodeling, reduce PRA, AngII, TXA2 and ET, increase PGI2 and NO, recover PGI2/ TXA2 and NO/ET balance , improve the function of autonomic nervous system, hemorheology and microcirculat ion. Conclusion:We can conclude that the mechanism of treatment of EH with Xueyaping depends on it’s inhibiting RAS ,protecting vessel endo? thelium and improve the function of autonomic nervous system, hemorheology and microcirculation.
