ABSTRACT
Objective To observe the efficacy of Shenfu Yangrong Decoction combined with routine Western therapy in the treatment of viral myocarditis (VMC) of Ⅰ– Ⅲ grades in children. Methods Totally 100 cases of VMC children were selected and divided into observation group and control group according to random number table method, with 50 cases in both groups. The control group was treated with routine Western therapy, while the observation group was combined with Shenfu Yangrong Decoction based on the control group, one dosage a day, twice a day, orally. The TCM syndrome scores, the serum levels of interleukin (IL)-17, IL-27 and nuclear factor - κB (NF-κB), the levevs of troponin Ⅰ (cTnⅠ) and cardiac free fatty acid binding protein (H-FABP) before and after treatment in both groups were compared, and the total incidence of adverse reactions during treatment was monitored. Results The total effective rate was 90% (45/50) in the observation group and 74% (37/50) in the control group. The observation group was significantly higher than the control group (χ2=4.336, P=0.037). Compared with before treatment, the scores of the main symptoms, the scores of the secondary symptoms, and the total scores of the two groups decreased significantly after treatment (P＜0.01). Comparing the two groups after treatment, the scores of main symptoms, scores of secondary symptoms and total scores of the observation group were significantly lower than those of the control group (P＜0.05, P＜0.01). Compared with before treatment, serum IL-17, NF-κB, cTnⅠ, H-FABP levels were significantly reduced (P＜0.01), while serum IL-27 levels were significantly increased (P＜0.01) in both group. After treatment, the levels of serum IL-17, NF-κB, cTnⅠ, and H-FABP in the observation group were significantly lower than those in the control group (P＜0.01), and serum IL-27 level in the observation group was significantly higher than in the control group (P＜0.01). The adverse reaction rate was 12% (6/50) in the observation group and 8% (4/50) in the control group, without statistical significance between the two groups (χ2=0.368, P=0.544). Conclusion Shenfu Yangrong Decoction combined with routine Western therapy for the treatment of viral myocarditis children of Ⅰ– Ⅲ grades can effectively reduce the symptoms of patients, inhibit inflammation, reduce myocardial injury, with high safety.
