Objective To study the effect of Shuxuening injection on treatment of left ventricular diastolic dysfunction.Methods Ninety cases of left ventricular diastolic dysfunction were divided into control group and test group randomly,45 cases for each group.Both groups were treated with standard management and the treatment group was given Shuxuening injection(20 mL) additionally for 2 weeks.E/A ratio,peak E,peak A,LVEF were observed before and after treatment.Result The clinical symptoms of the two groups were all improved after treatment.The test group had a higher overall effective rate than the control group.The ventricular diastolic function paramenters(E/A ratio,peak E,peak A,LVEF) in the test group were much better than that in the control group.Conclusion Shuxuening injection can improve the clinical symptoms and signs of left ventricular diastolic dysfunction.

AIM: To study the effects of M. vaccae on eosinophil apoptosis and Bcl-2 protein expression in lung tissues of asthmatic guinea pigs. METHODS: 30 guinea pigs were divided into normal saline (NS) group, asthma group and M. vaccae treatment group at random, every group included 10 guinea pigs. Guinea pigs in M. vaccae treatment group were injected intramuscularly with 22 5 ?g M. vaccae 10 days before OVA immunization. TdT-mediated dUTP nick end labeling (TUNEL) technique was used to investigate the apoptosis of eosinophils and immunohistochemistry method was used to study the expression of Bcl-2 protein in lung tissues. RESULTS: The apoptosis index (AI) of eosinophils in lung tissues in M. vaccae treatment group was significant higher than that in asthma group (23 78?5 42)% vs (4 56?0 68)%, P

Aim To study the immunoregulatory effect of Mycobacterium vaccae vaccine on asthmatic guinea pig.Methods 30 guinea pigs were randomly divided into NS,asthma and Mycobacterium vaccae vaccine groups. A guinea pig model of asthma was formed with ovalbumin.Every guinea pig of Mycobacterium vaccae vaccine group was intramuscularly injected with 22.5 ?g Mycobacterium vaccae vaccine 10 days before ovalbumin immunization.mRNA expressions of IL-4,IL-5 and IFN-? in lung tissue,total IgE and ovalbumin-specific IgE in serum were determined. Results For Mycobacterium vaccae vaccine group guinea pigs, mRNA expressions(optical density value) of IL-4(0.060?0.018) and IL-5(0.052?0.006)in lung tissue were significantly lower than those of asthma group(0.111?0.025,0.106?0.030 respectively; both P
