Abstract： Objective To observe the treatment efficacy in patients with hyperthyroidism by ~(131) radioactive iodine in conjunction with Jiakangshu oral solution.Methods 465 cases with hyperthyroidism were divided into control group(n=235)and treatment group(n=230).In the treatment group on the basis of ~(131) iodine therapy plus service Jiakangshu oral solution.The contents of T_3,T_4,FT_3,FT_4,TSH were observed before and after treatment.Results The cure rate 74.7% in treatment group after treatment 12-month was higher than 65.1%(χ~2=3.94,P＜0.05),total effective rate 88.6% was higher than 80.4%(χ~2=3.90,P＜0.05).The contents of T_3,T_4,FT_3,FT_4,TSH drop,but TSH levels increased in two groups after 12 months with those before treatment(t=2.745,2.778,2.845,2.812,2.833,all P＜0.05).The contents of T_3,T_4,FT_3,FT_4 in treatment group decreased significantly compared with the control group after treatment 12 months(t=2.145,2.178,2.245,all P＜0.05).The negative conversion rate of TGAb,TMAb in the treatment group were significantly higher than control group(χ~2=3.98,3.88,all P＜0.05).Conclusion The treatment effecs are obvious in patients with hyperthyroidism by 131 radioactive iodine in conjunction with JiaKangShu oral solution.
