目的：观察益脉降压流浸膏对老年气虚血瘀证Ⅱ期高血压病患者血浆神经肽Ｙ（ＮＰＹ）含量的影响。方法：将６８例患者随机分为两组，分别为益脉降压流浸膏（治疗组３６例）和卡托普利（对照组３２例）治疗；采用放射免疫法制定两组患者治疗前后血浆ＮＰＹ含量。结果：血浆ＮＰＹ含量治疗前两组患者均较健康老年人显著升高（Ｐ〈０．０１）；治疗后均显著降低（Ｐ〈０．０５或Ｐ〈０．０１），且治疗组优于对照组（Ｐ〈０．０１）。血

Effect of Yimai Jiangya Extract on Plasma Neuropeptide Y Level in Patients of Senile Hypertension with Qi Deficiency and Blood Stasis Syndrome

OBJECTIVE: To observe the effect of Yimai Jiangya extract (YMJYE) on plasma neuropeptide Y (NPY) level in patients of senile hypertension at stage II with Qi-Deficiency and blood stasis Syndrome (QDBSS). METHODS: Sixty-eight patients were randomly divided into two groups, 36 patients in the treated group treated with YMJYE and 32 patients in the control group treated with captopine. Radioimmunoassay was used to examine the level of plasma NPY before and after treatment in the two groups. RESULTS: Before treatment, plasma NPY level was significantly higher in both groups than that in the old healthy persons (P < 0.01), it lowered significantly after treatment and the decrement was more obvious in the treated group in comparing with that in the control group (P < 0.01). Blood pressure was significantly lowered in both groups after treatment (P < 0.01) but with no significant difference between them. CONCLUSION: Plasma NPY level was increased in patients of senile hypertension with QDBSS. YMJYE had good effect in lowering plasma NPY level and reducing blood pressure. It is presumed that the NPY lowering effect of YMJYE might be one of its mechanisms in lowering blood pressure.
