RESUMEN
Objective To observe the effect of β-blocker on dilated cardiomyopathy (DCM) in children.Methods Sixty-one children cases of DCM in this hospital from 1995 to 2015 were retrospectively analyzed and divided into the treatment group(taking β-blocker,n=35) and control group(non-taking β-blocker,n=26) according to whether taking β-blocker.The clinical effect of β-blocker was preliminarily observed.Results The heart rate,LVDD,LVSD and LA after treatment in the treatment group were significantly decreased compared with before treatment(P＜0.05),while EF was significantly increased(P＜0.05);LVDD after treatment in the control group was significantly decreased(P＜0.05),while hear rate,RV,LVDD,LVSD,LA,MV and EF had no obvious change compared with before admission(P＞0.05).The heart rate,LVDD,LVSD and EF after treatment had statistical difference between the treatment group and control group (P＜0.05),the heart function after treatment in the treatment group was significantly improved compared with the control group (P＜0.05).The heart function improvement degree after treatment in the patients with hypertension of the treatment group was significantly better than those with normal blood pressure(P＜0.05).DCM with hypertension was significantly improved after treatment and was better than DCM without hypertension (P＜0.05).The The heart function improvement degree after treatment in the patients with carvedilol treatment was obviously better than that in the patients with metoprolol treatment(P＜0.05).Conclusion β-blocker could be used in the treatment of DCM,its effect is especially good in DCM children patients with hypertension,in which the effect of carvedilol is better than that of metoprolol.

RESUMEN
Incidence of dilated cardiomyopathy of children is increasing in recent years. But, the pathogenesis remains obscure. Genetic factor. viral infection, autoimmunity and apoptosis may play some important roles in the pathogenesis of dilated cardiomyopathy. We will summarize the progress in pathogenesis of dilated cardiomyopathy of children.
RESUMEN
AIM: To establish the quality standard for Tianqi Tongjing Capsule(Radix et Rhizoma Notoginseng, Rhizoma Corydalis, Fructus Foeniculi, etc.). METHODS: Rhizoma corydalis, Rhizoma Chuanxiong, Radix Aucklandiae Pollen Typhae, Faeces Trogopteror in Tianqi Tongjing Capsule were identified by TLC. Ginsenoside Rg1 wsa determined by HPLC. RESULTS: The average recovery was 98.66% and RSD was 0.56% (n=5), respectively. CONCLUSION: The method is reliable, accurate and specific. It can be used for quality control of Tianqi Tongjing Capsule.
