Abstract:〔Abstract〕 Objective To investigate the clinical effect of application Jiawei Qingxuan Jiangya decoction combined with western medicine in the treatment of Yin deficiency Yang hyperactivity hypertension (HIN). Methods A total of 98 HBP patients with Yin deficiency Yang hyperactivity treated in Henan Provincial Hospital from June 2019 to June 2020 were selected and divided into control group and observation group by random number table method, with 49 cases in each group. The control group was treated with conventional western medicine treatment, and the observation group was treated with Jiawei Qingxuan Jiangya decoction on the basis of the control group. The clinical efficacy, serological indexes [tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and homocysteine (Hcy)], blood pressure levels [diastolic blood pressure (DBP) and systolic pressure (SBP), blood lipid levels [low density lipoprotein (LDL-C), total cholesterol (TC), high density lipoprotein (HDL-C) triacylglycerol (TG)] and safety were compared between the two groups. Results The total effective rate of the observation group was 97.96%, higher than 79.59% of the control group, the difference was statistically significant (P < 0.05). After treatment, the levels of IL-6, TNF-α and Hcy in the two groups were decreased to varying degrees, and the levels of IL-6, TNF- α and Hcy in the observation group were lower than those in the control group, the differences were statistically significant (P < 0.05). After treatment, the DBP and SBP in the two groups decreased to varying degrees, and the DBP and SBP in the observation group were lower than those in the control group, the differences were statistically significant (P < 0.05). After treatment, LDL-C, TG and TC in the two groups decreased to varying degrees, while HDL-C increased to varying degrees. LDL-C, TG and TC in the observation group were lower than those of the control group, and HDL-C in the observation group was higher than that of the control group, the differences were statistically significant (P < 0.05). There were no adverse reactions in the two groups during treatment. Conclusion The application of Jiawei Qingxuan Jiangya decoction combined with western medicine in HTN patients with Yin deficiency and Yang hyperactivity is beneficial to reduce blood pressure and blood lipids, reduce inflammatory reaction, and has high safety.
