Objective To explore the intellectual effects of arsenic in drinking water on children. Methods Intellectual effects were evaluated by computer-based reaction time and Combined Raven's Test. Children aged 9 to 11 years living in three villages of Inner Mongolia were investigated in April, 2006. The arsenic concentrations in the drinking water of the three villages were 0.16 mg/L, 0.09 mg/L and less than 0.05 mg/L (control group). Results The mean, fastest and slowest visual reaction time of children exposed to the high levels of arsenic through drinking water were longer than those of children in control. The differences of mean, fastest and slowest visual reaction time between girls exposed to 0.16 mg/L arsenic and control were significant; the differences of the mean and slowest visual reaction time between 10-year old children exposed to 0.16 mg/L arsenic and control were significant. IQ of girls exposed to 0.16 mg/L arsenic was significantly lower than that in control. Conclusion Intellectual function of children can be affected by arsenic in drinking water, and the intellectual effects of arsenic on girls are more obvious.

Objective To describe the health literacy level and to explore the effect of health literacy level on education retention of patients with stroke.Methods Totally 100 stroke survivors were selected as the subject by convenience sampling.They were evaluated by Short Test of Functional Health Literacy in Adults on admission,and they accepted 60-90 minutes education intervention during hospitalization.Evaluation retention were measured before discharge.Results The score of the overall health literacy was (15.60±1.36) points,among of them,low level was 37 cases,general level was 24 cases,high level was 39 cases.Age,education level and Mini-Mental Status Exam score had a significant effect on the health literacy of patients with stroke (x2/F=14.248,12.082,11.329,P＜ 0.05).After education intervention,the score of education retention was (6.69±2.00)points,and the score of education retention in low,general,high level health literacy were (5.08±2.06),(7.46±1.61),(7.51± 1.76) points,and there were significant differences(F=14.223,P ＜ 0.05).Heahh literacy had a effect on education(P ＜ 0.01).Conclusions The level of health literacy of stroke patients has the effect of improving the education retention.Improving and maintaining the health literacy of stroke patients should be the development direction of the prevention and treatment of stroke diseases.

Objective To investigate the effect of tumor necrosis factor-α (TNF-α) on the levels of ezrin-radixin-moesin (ERM) proteins and the phosphorylated ERM proteins (p-ERM) in rat pulmonary microvascular endothelial cells (PMVEC),and to explore Rho kinase (ROCK) influencing on modulation of the ERM proteins phosphorylation.Methods Cultured rat pulmonary microvascular endothelial cells were randomly divided into dose-dependent and time-dependent groups.In dose-dependent group,cells were cultured with different doses of TNF-α (0,0.1,1,10 μg/LTNF-α) for 60 min.In time-dependent group,cells were cultured with TNF-α (10 μg/L) for 0,15,30,60,90,120,180 min.In ROCK inhibitor (Y27632) intervention group,cells were cultured with TNF-α (10 μg/L) or Y27632 (30 μmol/L) + TNF-α (10 μg/L) for 60 min respectively.The levels of ERM proteins and p-ERM were determined by western blot.One way analysis of variance (ANOVA) was employed for statistical analysis by using SPSS version 16.0 software to compare values among all groups.A significant difference was presumed as a P value ＜ 0.05.Results Western blot revealed that ERM and p -ERM proteins were present in rat PMVEC.Stimulation withTNF-α gradually up-regulated the level of pERM proteins in a dose-dependent manner [0 μg/LTNF-α group:(0.648 ± 0.102),0.1 μg/LTNF-αgroup:(0.728-±0.082),1 μg/LTNF-α group:(0.926±0.121),10 μg/LTNF-α group:(1.245 ±0.134),all P =0.000].In time-dependent group,the level of p-ERM proteins rose at 15 min (0.777 ±0.151),peaked at 90 min (1.295 ±0.176),then decreased gradually at 120 min (0.802 ±0.139),but stayed higher level at 180 min (0.669 ±0.128) than that in un-stimulated 0 min group (0.631 ±0.123,P=0.004,0.000,0.001,0.016,respectively).When PMVEC pre-incubated with ROCK inhibitor and TNF-t,the level of p-ERM proteins caused a marked attenuation of TNF-αstimulation [(0.634 ± 0.112) vs.(0.875 ± 0.164),P =0.002],however,there are no significant differences compared to ROCK inhibitor alone group (0.661 ± 0.108) and no intervention group (0.654 ± 0.125),P =0.973,P =0.900,respectively).Conclusions TNF-α could induce up-regulation of the level of the phosphorylated ERM proteins in rat PMVEC,and ROCK signal molecules might involve in modulation of the ERM proteins phosphorylation.

Objective To observe the effects of high fat diet and 6?week voluntary wheel running on the structure of hypothalamus, pituitary and testis and sex hormone levels in pubertal male rats. Methods Forty 3?week?old male Spra?gue?Dawley rats were randomly divided into following groups: the control group fed with normal diet (C), training group fed with normal diet ( CE) , control group fed with high fat diet ( D) , and training group fed with high fat diet ( DE) , 10 rats in each group. The groups C and D were bred for 8 weeks freely, and the groups CE and DE were assigned to have vol?untary wheel running twice/d, 1 h/time, 5 d/w, for 6 weeks after a 2?week adaptive feeding. Eight weeks later, blood sample was collected to detect the serum T, E2 , FSH and LH, and the E2 and T of testis were also detected. The histology of hypothalamic, pituitary, and testis tissues was observed by light microscopy. Results ( l) Compared with the group C, the group D had significantly decreased levels of serum T and E2 and testicular T (P<0?05), and significantly increased serum E2, FSH and LH levels (P<0?05). In the group D, vacuolar lipid droplets were increased in the hypothalamus, e?osinophils and basophils were reduced in the pituitary, and the area of seminiferous tubules, percentage of sperm cells, and quantity of Leygid cells were significantly decreased in the testis. (2) Compared with the group D, the serum T and testic?ular T concentrations were increased, but the serum E2, FSH and LH were decreased significantly (P<0?05) in the group DE, and vacuolar lipid drops were increased in the hypothalamus, eosinophil cells were increased in the pituitary gland, and the area of seminiferous tubules was increased but not significantly in the testis. Conclusions 6?week voluntary wheel exercise can improve the high fat diet?induced abnormal secretion of sex hormones, but not effectively improve the histologi?cal changes in hypothalamus, pituitary gland and testis.
