Objective:To explore the efficacy of gamma globulin at different doses combined with dexamethasone in the treatment of children with severe idiopathic thrombocytopenic purpura. Methods: Totally 96 cases of patients with idiopathic thrombocytopenic purpura were divided into group A ( standard high dose of gamma globulin+dexamethasone) , group B ( middle dose of gamma globulin+dexamethasone) and the control group ( dexamethasone) . The clinical effects and platelet parameters of the three groups were com-pared. Results:The levels of PLT, PCT and PDW in group A and group B after the treatment were higher than those in the control group(P<0. 05). The recovery time of normal platelet and the stop time of bleeding in group A and group B were lower than those in the control group(P<0. 05), and there was no significant difference between group A and group B(P>0. 05). The clinical effective rate of group A and group B was higher than that in the control group(P<0. 05), and there was no significant difference between group A and group B(P>0.05). There was no significant difference in the incidence of adverse reactions among the three groups (P>0. 05). Conclusion:Gamma globulin at middle dose shows significant effect as at high dose in the patients with ITP, which can reduce the dosage and is worthy of clinical promotion.

Objective To study the molecular mechanism of injection with hepatocyte growth factor (HGF) at different doses on angiogenesis in myocardium of dogs with acute myocardial infarction (MI).Methods Sixteen 1.5-year-old male hybrid dogs,weighing 11-13 kg,were divided into 500 ?g HGF treatment group,1 000 ?g HGF treatment group,sham operation group,and no MI interference group,4 dogs in each group.Expressions of VEGF,HGF,CD31,and platelet factor Ⅷ in myocardium of dogs with MI were detected,the number of micro blood vessels was calculated,and correlation between angiogenesis and expression of HGF and VEGF was analyzed in 28 d after the model was established.Results HGF gene therapy could up-regulate the expression of CD31 and VEGF.The expression of CD31 and VEGF mRNA was 0.82 and 0.39 respectively in 1 000 ?g HGF group,and 0.47 and 0.21 respectively in 500 ?g HGF group.The expression of VEGF mRNA was 0.09 and no expression of CD31 mRNA was found in MI group.HGF could increase the angiogenesis in infracted myocardium.The microvascular density was 126.4?10.6,79.8?6.0,and 21.7?2.5/mm2,respectively,in 1 000 ?g HGF group,500 ?g HGF group,and MI group (P

Objective To discuss the recent effect of professional instruction on patients with type 2 diabetes mellitus. Methods 200 patients with type 2 diabetes mellitus were divided into the observation group and the control group. The observation group received professional instruction while the control group only got doctors'simple advice about the characteristic, results and attentions of diabetes mellitus. Various in dices were determined before and 3 months after intervention and patients compliance was evaluated 3 months after intervention. Results The indices such as blood glucose,glycosylated hemoglobin, urine trace protein, blood lipid, weight index, blood pressue and waistline were different between the two groups(P＜0.05) after intervention although no difference was seen between them before intervention(P＞0.05).The patients compliance in the observation was better compared with the control group(P＜0.01). Conclusion Application of professional instruction proved to be an effective method to alleviate the symptoms of patients with type 2 diabetes mellitus.
