Objective To explore whether expertise-novice effect on representational momentum exist among athletes in the university football and volleyball team and common college students.Methods We used implied motion paradigm in experiment 1 and smooth motion paradigm in experiment 2.Results There were no significant differences on representation momentum among football players,volleyball players and college students in the implied motion paradigm.When moving to the right at a high speed,college students' displacement was larger than athletes in smooth motion paradigm,but no significant differences were found between football and volleyball players in the displacement.Conclusion The expertise-novice effect on representational momentum has been found under the condition of high speed and moving right using smooth paradigm.There is no difference between football and volleyball on representational momentum.

Objective To investigate the association between serum N-terminal pro brain natriuretic peptide(NT-ProBNP) and creatine kinase myocardial(CK-MB),cardiac troponin I(cTnI) in children who were diagnosed as viral myocarditis(VMC),and to explore the clinical significance.Methods Fifty children with VMC were selected as VMC group who were further divided into cTnI(+)group and cTnI(-)group.Fifteen healthy children were selected as healthy control group.The levels of myocardial enzyme of the 2 groups were tested by automatic biochemical analyzer and level of NT-proBNP was detected by specific NT-proBNP enzymelink immunosorbent assay(ELISA) kit.SPSS 13.0 software was used to analyze the data.Results 1.There were 23 cases with positive cTnI and 27 cases with negative cTnI.The levels of NT-proBNP in VMC group including cTnI positive and cTnI negative were significantly higher than those in healthy control group (P0.05).2.In the group with positive cTnI,the level of NT-proBNP was correlated with cTnI.The coefficient of determination was 0.17.3.In the group with negative cTnI,the level of NT-proBNP was correlated with CK-MB.The coefficient of determination was 0.34.NT-proBNP presented a increasing trend during interval of 25-100 U?L-1 and 175-255 U?L-1 of CK-MB.Conclusions The levels in the serum NT-proBNP in VMC children were higher than those in healthy children.Serum detection NT-proBNP may be applied as a new approach in diagnosis of VMC in children.

Objective: To analyze the effect of three therapeutic methods to find an optimal approach to the treatment of intracranial bacterial infection by retrospectively reviewing 33 intracranial bacterial infection patients who were admitted from 1995 to 2008 in our hospital. Methods: The treatments by intermittent lumbar puncture, continuous lumbar subarachnoid space drainage, and embedment of Ommaya cyst for continuous drainage from the ventricles were performed in 15 cases, 12 cases, and 6 cases respectively along with intravenous application of full dose of antibiotics. Results: Nineteen cases were cured and the best prognosis was from the group of Ommaya cyst embedment and continuous drainage from the ventricles. Conclusion: Management goals are prompt recognition of the central nervous system (CNS) infection, rapid identification of causative organisms and initiation of treatment with the optimal management methods for complications. Embedment of Ommaya cyst for continuous drainage from the ventricle is a safe and effective treatment for intracranial bacterial infection.

Objective To study the validity of furosemide test for predicting the hematoma enlargement in pa- tients with hypertensive cerebral hemorrhage.Methods Four hundred fifty-one patients with hypertensive cerebral hemorrhage were diagnosed using CT after oneset of the disease and 24 h reexamined 24 h after.The incidence of enlarged hematoma was evaluated by comparison the baseline and 24 h CT scanning.Furosemide(20 mg iv)was ad- ministered and blood pressure was measured 30 min after furosemide.Results The decreasing level of MAP after furosemide was significantly inversely related with incidence rate of hematoma enlargement{ r=-0.94,t=58.4,P 10 mmHg as the cut-off point,with the rate of hematoma enlargement as being 6.4 %,MAP decreased≤10 mmHg was associated with increases in prevalence of hematome to 33.2 %(?~2=51.82, P

Objective To investigate the relationship between carotid atherosclerosis(CAS)plaque and its related factors and cerebral infarction(CI).Methods The 91 patients with CI were detected by Color Doppler and the levels of plasma lipid,blood glucose(BG)and fibrinogen(Fbg)were evaluated,and compared with normal control(NC)group.Results(1)Compare with NC group,the IMT,prevalence of CAS plaque,the rates of soft plaque in CI group were significantly higher(all P
