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 investigate the effects of simvastatin on the abatement of the mRNA,protein expression of RhoA and the improvement of the cardiac remodeling and cardiac disfunction after the myocardiac infarction in rats.Methods Rats were divided into 3 groups: the control group,the myocardiac infarction group and Simvastatin intervened group.After 8 weeks,cardiac weight index and hemodynamics were observed,mRNA and protein expression of RhoA in cardiac muscles was measured. Results Compared with the control group,the cardiac weight index and the mRNA and protein expression were increased in rats with myocardiac infarction and the hemodynamics was worsened(P

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 investigate physical activities of preschool children by gender and to explore the effects of activity type on bone indexes.Methods During 2009 and 2010,397 preschool children of 3-5 years old were randomly selected from 4 kindergartens in Chengdu Province of China.Ultrasound bone analyzer was used to assess children's bone mass.A physical activity questionnaire was completed by parents to evaluate physical activities at leisure time.Student's t test and least square regression were used for data analysis.Results Concerning activity types,boys spent more leisure time on running and Wushu than girls did (t values were 1.94 and 2.84,respectively ; both P ＜ 0.05).However,girls spent more time on dancing (0.78 h),jumping rope (0.08 h) and manual labour (0.22 h) each day (t values were-9.50,-3.43 and-1.92,respectively; all P ＜ 0.05).The weekly total exercise time and energy consumption per unit of body weight of girls vs.boys were 7.29 vs.6.51 h and 127.57 vs.113.85 kJ (t values were 2.63 and 2.04,respectively ; both P ＜ 0.05).About per day time on sleeping and per week time on watching television,there were no significant difference between boys and girls (t =0.180,0.520;P ＞0.05).But boys spent more time on electronic game and computer than girls (t =0.760,2.510;P ＜ 0.05).The normalized correlation coefficient for bone mass and moderate physical activities or jumping was 0.184 and 0.275,respectively (both P ＜ 0.05).Conclusions Our data suggest that preschool children's bone volume may be positively correlated with moderate physical activities and jumping activities.Introducing some moderate physical activities or activity appliance,toys and playing fields as well as increasing professional training might be helpful.

In order to improve the efficiency and quality of medical services,the authors applied the lean production and system simulation into optimizing the transfusion system of a hospital.By means of describing and analyzing the current situation and problems of a transfusion system of the hospital,the paper presented the cause-effect diagram for overlong patient waiting.5W1H and ECRS were adopted to analyze the infusion processes,while Simio was used to simulate the existing infusion system and simulation data so obtained were used to draw a value stream mapping for the system.In line with the ideas of Shojinka and one stream production,nurses deployment and conveyor speed were reconfigured.Based on these ideas,a reform plan is presented and the simulation method is used to verify the outcomes.The study proved that lean production and system simulation can effectively improve the hospital transfusion system,medical efficiency and medical service level.

Objective To investigate the difference of leucorrhea routine tests results among 3 periods of pregnancy in pregnant women.Methods Vaginal cleanliness,the presence of clue cells,trichomonas and fungi were tested for 3 103 obstetric outpatients who were pregnant and treated in the hospital.The test results were analyzed and compared.Results Among pregnant women in different periods of pregnancy,the difference in the proportion of vaginal cleanliness degree Ⅲ and fungal infection rates were statis-tically significant(P <0.05).Among pregnant women of different pregnant periods with vaginal cleanliness degree Ⅱ,difference of fungi infection rate was statistically significant(P <0.05).Among pregnant women of different pregnant periods with vaginal clean-liness degree Ⅳ,the difference of positive rates of fungi,trichomonas and clue cells were statistically significant(P <0.05).In addi-tion,there are a number of mixed infections.Conclusion Vaginitis during pregnancy should be early detected,diagnosed and trea-ted.

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.

ObjectiveTo observe the clinicalefficacies of ginger-partitioned moxibustion in three different periods, i.e. the canicular days, the Spring Equinox, and the Autumnal Equinox, in treating allergic Rhinitis.MethodEighty-nine patients with allergic rhinitis were elected and divided into3 groups by using the random number table (canicular group, Spring Equinox group, and Autumnal Equinox group), to receive the same treatment with same point selection. The change of serum IgE and improvement of symptoms were observed after the intervention in the three groups.ResultThe three groups all showed significant decrease of serum IgE and improvement in the symptoms of allergic rhinitis (P<0.05), and the therapeutic efficacy of the canicular group was markedly higher than that of the Spring Equinox group (P<0.05) and the Autumnal Equinox group (P<0.05).ConclusionThe canicular days are the optimal timeperiodfor the treatment of allergicrhinitis.
