Abstract:ObjectiveTo investigate the clinical effect of Baihe Dihuang Pingkang decoction on hyperthyroidism.Methods A total of 90 patients with hyperthyroidism from April 2017 to March 2018 were selected and divided into control group ( n=45,routine Western medicine treatment) and observation group ( n=45,routine Western medicine treatment+Baihe Dihuang Pingkang decoction) randomly.The level of thyroid hormone,the improvement of Chinese medicine symptoms and the incidence of adverse reactions were observed.Results After treatment,the levels of serum thyroid stimulating hormone(TSH) in the observation group was higher than that in the control group,and the free triiodothyronine (FT3)and free thyroxine(FT4) were lower than those in the control group ( P<0.01).After treatment,Chinese medicine symptom score in observation group was significantly lower than that in control group (1.74±0.75 vs 6.46±3.21, t=9.605, P<0.01).After treatment,the levels of serum TG,TC,HDL-C and LDL-C in the observation group were significantly better than those in the control group ( P<0.01).The total effective rate of observation group was significantly higher than that of control group (95.56% vs 75.56%, χ2=7.282, P<0.01).Compared with control group,the total incidence of adverse reactions (2.22% vs 17.78%, χ2=6.409, P<0.05) and recurrence rate (0 vs 13.33%,χ2=6.429, P<0.05) were significantly lower in the observation group.Conclusion On the basis of routine Western medicine treatment,Baihe Dihuang Pingkang decoction could reduce adverse reactions and improve the overall efficacy effectively.
