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

ObjectiveTo explore the change of ranges of abduction motion of hip joint in the simplified Taichi quan exercise.MethodsThe ranges of abduction motion of hip joint of 30 healthy male young subjects were measured using a goniometer.ResultsThe ranges of abduction motion of both hip joints had markedly exceeded their normal ranges of 0°-45°abduction motion during the exercise.ConclusionThe simplified Taichi quan can strengthen hip abductors to prevent and correct the deformity of hip adduction.

Objective To investigate the effect of the inhibitor SB203580 of p38 mitogen-activated protein kinase (MAPK) signal transduction pathway on biopterin (BH 4)/nitric oxide (NO) expression and elucidate the potential mechanism of MAPK in biopterin-mediated NO induction after endotoxic shock. Methods A total of 56 male Wistar rats were randomly divided into normal control group (n=8), endotoxic shock group (n=32) and SB203580 treatment group (n=16). After animals were sacrificed, tissue samples from the liver, the lungs as well as the kidneys were harvested to determine the expressions of guanosine triphosphate cyclohydrolase I (GTP-CHI) and inducible nitric oxide synthase (iNOS) mRNA and observe the changes of BH 4 and NO levels in blood and tissues. Results With endotoxin challenge, GTP-CHI mRNA expression and BH 4 levels were significantly elevated in various tissues and maintained at high levels up to 24 hours. Similarly, the iNOS mRNA expression and NO levels in the tissues significantly increased too, especially in the liver and the lungs. Treatment with SB203580 significantly down-regulated GTP-CHI mRNA expression in the liver, the lungs and the kidneys at 12, 24 and 2-12 hours, respectively (P
