Objective To investigate the clinical effect of Sanjin Tablets combined with compound sulfamethoxazole in treatment of acute pyelonephritis. Methods Patients (106 cases) with acute pyelonephritis in Fengrun District Hospital of Traditional Chinese Medicine in Tangshan from March 2015 to March 2018 were randomly divided into control (53 cases) and treatment (53 cases) groups. Patients in the control group were po administered with Compound Sulfamethoxazole Tablets, 2 tablets/time, twice daily. Patients in the treatment group were po administered with Sanjin Tablets on the basis of the control group, 3 tablets/time, three times daily. Patients in two groups were treated for 14 d. After treatment, the clinical efficacy and disappearance time of clinical symptoms were evaluated, and changes of urine routine indexes, blood routine indexes and serological indexes in two groups before and after treatment were compared. Results After treatment, the clinical efficacy in the control and treatment groups were 81.1% and 94.3%, respectively, and there were differences between two groups (P < 0.05). After treatment, the disappearance time of chills, fever, lumbago and urinary tract irritation in the treatment group was significantly shorter than that in the control group, and there were differences between two groups (P < 0.05). After treatment, the number of WBC and RBC of urine, WBC and NEU% of blood in both groups were significantly lower than that before treatment, and there were differences in the same group (P < 0.05). After treatment, the number of WBC and RBC of urine, WBC and NEU% of blood in the treatment group were lower than those in the control group, and there were differences between two groups (P < 0.05). After treatment, IL-8, CRP, and PCT in both groups were significantly lower than that before treatment, and there were differences in the same group (P < 0.05). After treatment, IL-8, CRP, and PCT in the treatment group were lower than those in the control group, and there were differences between two groups (P < 0.05).
