Objective To study the effects of ? blocker on heart rate variability (HRV) of dilated cardiomyopathy and ? receptor sentivity and cardiac function.Methods HRV was analyzed by use of Holter monitoring and isopnenaline sensitivity test was performed in patients with dilated cardiomyopathy.CD 25 was measured.Cardiac function was measured by use of ultrasonography.Results SDNN,LF,HF and HRVI in the treatment group were increased compared with those before treatment(P

Objective To explore the efficacy and adverse reactions of diminishing scheme of cefaclor sustained re-lease tablets in the treatment of recurrent urinary tract infection(RUTI).Methods 60 RUTI patients in a hospital were divided into treatment group(n=30)and control group (n=30),patients in treatment group were treated with diminishing scheme of cefaclor sustained release tablets,patients in control group were treated with diminishing scheme of levofloxacin tablets,clinical therapeutic efficacy and adverse reactions of two groups were observed. Results The curative rate in treatment group was higher than control group ([80.00%,n =24]vs [53.33%,n =16])(χ2 =4.80,P =0.028).The incidence of RUTI in treatment group was lower than control group ([6.67%,n=2]vs [26.67%,n=8])(χ2 =4.32,P =0.038).Incidence of adverse reactions in treatment group was lower than control group (16.67% vs 50.00%)(χ2 =7.50,P =0.006).Conclusion The diminishing scheme of cefaclor sus-tained release tablets in the treatment of RUTI has good curative efficacy,low recurrence rate,fewer adverse reac-tions,and can be used for the treatment of recurrence of RUTI.
