Objective: To investigate the short-term effects of ischemic preconditioning (IP) on left ventricular diastolic function in diabetic patients with acute myocardial infarction(AMI). Methods: Totally 188 patients with first AMI were studied. Eighty-one patients without diabetes were divided into group A (with IP) and group B (without IP). The other 107 patients with diabetes were divided into group C (with IP) and group D (without IP).The effect of IP on peak creatine kinase value and left ventricular diastolic function were analyzed separately. Results: The peak creatine kinase value, the peak creatine kinase MB fractions and the incidence of E/A

Objective To investigate the prevalence of urticaria among children aged 2-6 years in Nanjing city.Methods A questionnaire survey was carried out in children aged 2-6 years in 5 main districts of Nanjing City.Results The number of valid questionnaires was 13 610,accounting for 92.8％ of total respondents.Among the 13 610 respondents,1 116 were diagnosed as urticaria,including 565 boys and 551 girls,with the total prevalence rate being 8.54％.No significant difference was observed in the prevalence rate of urticaria between boys and girls (8.49％ vs.8.60％,x2 =0.04,P =0.832) or among children of different age groups (x2 =1.84,P =0.17).The prevalence of urticaria increased with age,and positively correlated with parents' educational level (rs =0.96,P =0.000).Children born in urban areas showed higher prevalence of urticaria than those in rural areas (8.79％ vs.5.56％,x2 =13.98,P =0.000).Conclusions The prevalence of urticaria has increased among children aged 2-6 years in recent years.More studies should be carried out to investigate into the pathogenesis and relevant factors of urticaria,so as to facilitate its prevention and treatment.

Objective To observe the effects of epidermal growth factor (EGF) on cell proliferation and cell cycle of cultured bovine corneal endothelial cells. Methods Bovine corneal endothelial cells were cultured with different concentrations of hEGF (1, 10 and 100 ng/mL). MTT test was performed to evaluate the cell proliferation. The bovine corneal endothelial cells were divided into two groups:control group (cultured in DMEM) and EGF-stimulated group (cultured in DMEM with EGF). Flow cytometry was performed to determine the cell cycle phases on the third and seventh day. Results Compared with the control, EGF enhanced the cell proliferation in a dose-related response. 10 ng/mL and 100 ng/mL EGF were much more effective than 1 ng/mL.On the third day, S phase cells accounted for 24.5% and G_2-M phase cells 0.08% in the control group,while 24.6% and 0.06%, respectively in the EGF-stimulated group. However, on the seventh day, those came to 20.8% and 0.41% in the control group, and 18.2% and 1.55% in the EGF-stimulated group,indicating a significant change in the cell cycle (P

A Comprehensive review was present on the sources, enzyme stru cture, enzyme reaction mechanism and the application of the nitrilase.

The assessments of oocyte quality were usually needed in assisted reproductive technology and reproduction science.Based upon the changes of structure and biochemistry in the development of oocyte,assessments of oocyte quality mainly comprised the oocyte morphology and its maturity.The assessment method of oocyte quality from nondestructive manner and invasive technique to provide multi-pathway for evaluating the oocyte quality reasonable was discussed.

Objective To explore the protective effect of L-carnitine on neonates with myocardial injury caused by as?phyxia. Methods Forty-four neonates with myocardial injury caused by asphyxia were randomly divided into L-carnitine treatment group (21 cases) and control group (23 cases). Patients in control group were received routine treatment and pa?tients in treatment group were given L-carnitine 0. 1 g/(kg · d) on the basis of routine treatment for 7 days. Symptoms and physical signs were observed before therapy and during the treatment in two groups. Before and after the treatment, plasma levels of free L-carnitine and cardiac troponin I (cTnI) were detected with the method of colorimetric assay and chemilumi?nescent, respectively. Results The clinical effective rate was significantly higher in treatment group than that of control group (90.48%vs 60.87%, P<0. 05). Compared with the control group, there was a significantly higher plasma concentra?tion of free L-carnitine in treatment group after treatment [(27.00±5.69)μmol/L vs (13.20±3.04)μmol/L, P<0.05]. In treat?ment group, plasma concentration of free L-carnitine was significantly higher after treatment than that of pre-therapy [(14.87 ± 3.95)μmol/L,P<0.05]. Compared with the control group, there was a significantly lower plasma concentration of cTnI after treatment in treatment group [(0.025±0.006)μg/L vs (0.046±0.010)μg/L, P<0.05]. In the treatment group, there was a significant correlation between decreased plasma concentration of cTnI and increased plasma concentration of free L-carnitine (r=0.899, P<0.05). Conclusion Administration of L-carnitine can effectively decrease the abnormal plasma lev?el of cTnI in neonates with myocardial injury caused by asphyxia, and thereby protect the myocardium.

Objective To investigate the prevalence of atopic dermatitis (AD) among children aged 2-6 years in Nanjing city.Methods A questionnaire survey was carried out in children aged 2-6 years in 7 main districts of Nanjing City.Results A total of 13 061 children were investigated,among which,768 were diagnosed as AD,including 410 boys and 358 girls.The prevalence rate of AD was 5.88％ (95％ CI,5.48％-6.28％) in total,6.16％ (95％ CI,5.59％-6.74％) in boys and 5.59％ (95％ CI,5.02％-6.15％) in girls.Higher prevalence rate of AD was observed in boys compared with girls,and in children whose place of birth was in urban areas compared with those in rural areas.In addition,the prevalence rate of AD increased with age and with the rise in parental educational level.Conclusions Rapid economic development has dramatically changed life habits,dietary structure and residential environment of people,which can influence the prevalence of AD.
