Objective To explore the pathogenesis of autism by observation of changes of brain-derived neurotrophic factor(BDNF) positive neurons and the morphology of pyramidal cells in hippocampal CA1 region,and provide theoretical evidence for the therapeutic schedule.Methods Animal model of autism was obtained by Schneider method.Using the immunohistochemistry methods and image analysis,the number of BDNF positive neurons was examined in hippocampal CA1 region of the autism model rats and the normal rats,and the changes of pyramidal cell were observed in hippocampal CA1 region after HE staining.Results The numbers of BDNF positive neurons in the hippocampal CA1 region of the autism model rats were more than those of the normal rats (5.00 ±1.60 vs 3.00 ± 1.04,t =3.63,P =0.0015).The morphology of pyramidal cells showed that the pyramidal cells of the autism model rats in hippocampal CA1 region had apoptosis.Conclusion The occurrence of autism may be related to the changes of BDNF and the morphology of pyramidal cells in hippocampal CA1 region.

Objective：To compare the epidemiology and clinical characteristics of attention deficit hyperactivity disorder (ADHD) in adolescents (12～16 years) and school-age children (6～11years) to provide reference data for a comprehensive intervention to children ADHD.Methods：A population-based questionnaire study was conducted among subjects aged 6～16 years sampled from schools in Northern Shandong.Totally 4263 children (adolescents 2358,school-age children 1905) were chosen by stratified-clustered-random sampling.The estimation of ADHD was investigated by asking the parents to complete ADHD questionnaires and subjects were followed up.The diagnosis for ADHD was made according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV)cliterca,which was divided into three kinds of subtypes in accordance with distribution of symptom dimensions.Results：The total prevalence of ADHD was 6.4% in this sample,which was predominated by the inattentive type (ADHD-I ) (63.7％).The prevalence of ADHD was higher in males than in females (8.9% vs.4.1%,P<0.001),and lower in adolescents than in school-age children (5.3% vs.7.7%,P=0.002).Distribution of subtypes was different in ADHD children of different age.Compared with school-age children group,the hyperactive/impulsive type (ADHD-HI )and combined type (ADHD-C) were lower,and the inattentive type (ADHD-I )was higher in adolescent group (P<0.001).The prevalence of 3 symptomatic factors of inattention and 6 symptomatic factors of hyperactivity/impulsivity in adolescents ADHD was lower than that in school-age children ADHD.Conclusion：Inattention is central symptom for children ADHD.ADHD,symptom of hyperactivity/impulsivity especially in the elder groups have trends of lower prevalence rate.

Objective To investigate the feature of pathogenic bacteria in central venous catheter related infection (CVC-RI)and risk factor in the emergency intensive care unit (ICU).Methods One hundred and three patients were checked out bacteria from January 2006 to December 2008 in the ICU who were central venous catheter and corresponded with diagnostic criteria for CVC-RI.They were analyzed retrospectively.Results The ratio between Gram-postive bacteria (37.9%,39/103)and Gram-negative bacteria (42.7%,44/103)were not statistically significant,however,CVC-RI was related to applying duetal number,duct keeping on time and elect location.Duct staying in subclavian vein had the fewest chance.Conclusions It would be better to choose duct staying in subclavian vein.control remaining time and luminal number,and monitor changing pathogenic bacteria strictly.Main measures are taken to evade the pollution on the ental and external lumina.

Objective To investigate the effects of normobaric hyperoxia intervention on learning and memory abilities of valproic acid(VPA) autism model rats and the morphology of pyramidal cells in hippocampus CA1 area.Methods Animal model groups of autism were obtained in male offspring of the Wistar rats that received intraperitoneal injection of 600 mg/kg VPA at the 12.5 day after pregnancy.According to the eye opening time,behavior,weaning weight and the learning and memory abilities which were evaluated by the Y electricity maze test at the 28th day after birth,40 male VPA autism model rats were randomly selected 20 only and divided into normobaric hyperoxia model group (group A,n =10),atmospheric air model group (group B,n =10).Normal control groups were obtained in male offspring of Wistar rats that received intraperitoneal injection of equivalent physiological saline at the same period pregnancy.(group C,n =10).Rats in group A were treated with oxygen for 1 h per day and lasted 1 week;group B and C were treated with normal air.The learning and memory abilities of three groups were assessed at the 35th day after birth.The immunohistochemistry methods and image analysis were used to observe the pyramidal cells of autism model rats in hippocampal CA1 region.The effect of normobaric hyperoxia therapy on pyramidal cell of autism model rats in hippocampal CA1 region were evaluated by HE staining technique.Results The trying times of group A after treatment were less than those before treatment (31.15 ± 0.99 vs 31.54 ± 0.97,t =2.739,P =0.018).The memory times were more than those before treatment (3.00± 0.58 vs 2.69 ± 0.48,t =-2.309,P =0.040).The trying times of group A after treatment were less than those in group B after treatment (P =0.016).The memory times of group A were not different from that in group B after treatment(P=0.810).The morphology of pyramidal cells in hippocampal CA1 region showed that the pyramidal cells of the autism model rats had apoptosised.The number of apoptotic cells reduced and the number of normal form cells increased after the normobaric hyperoxia intervention compared with the autism model rats.Conclusion Normobaric hyperoxia intervention can improve the learning and memory abilities of the autism model rats.The apoptosis of the pyramidal neurons in hippocampal CA1 might be reduced after the normobaric hyperoxia intervention.

Objective To investigate the effects of hyperbaric oxygen on learning and memory ability in rats with a model of VPA autism and on the pyramidal cells in the CA1 region of the hippocampus.Methods An animal model of autism was established in the offspring of Wistar rats which had received a single intraperitoneal injection of sodium valproate at the 12.5th day of pregnancy.A total of 48 male VPA autism model rats were randomly divided into the hyperbaric oxygen group,a high pressure air group,a normal pressure high oxygen group and a normal pressure air group (each group with 12 rats).A normal control group was obtained by injecting physiological saline.The autism model rats of the hyperbaric oxygen group were treated with high pressure oxygen in an animal experiment cabin which was cleaned with pure oxygen for 10 min,pressurized for 15 min,held at 2.0 atmospheres absolute (ATA) for 45 min and then had the pressure relieved over 15 min.For the high pressure air group the cabin was pressurized with air for 15 min,held at 2.0 ATA for 45 min and the pressure was relieved over 15 min.For the normal pressure,high oxygen group the cabin was cleaned for 10 min with pure oxygen,then pure oxygen was supplied for 1 hour with the cabin door open.The normal pressure air group rats were placed in the open cabin with no pressure or additional oxygen.The testing lasted 7 days for 1 hour per day.The normal control group rats were placed in ordinary cages.Learning and memory were evaluated using the Y electric maze test before and after the interventions.Any changes in the pyramidal cells in the CA1 region of the hippocampus were observed after hematoxylin and eosin (HE) staining.Results The average number of tries of the hyperbaric oxygen group after treatment was significantly less than before treatment and memory retention times were increased.The number was also less in the normobaric hyperoxia group and memory retention times again improved.The number of apoptotic cells was reduced and the number of normal form cells in the CA1 region increased after the hyperbaric oxygen intervention.Conclusions The learning and memory abilities of the autistic rats improved after the hyperbaric oxygen intervention.Pyramidal cells in the CA1 region proliferated and the number of apoptotic cell decreased.This may be the mechanism by which hyperbaric oxygen intervention treats autism.

Objective:To examine the association between living conditions and physical activity of older adults in Shanghai communities, and to explore the impact of living alone on different types and intensities of physical activity.Methods:Participants included randomly recruited older adults aged 60 and above in the Hongqiao, 2nd Shimen Road and Weifang communities in Shanghai.The Physical Activity Scale for the Elderly(PASE)was used to investigate the physical activity status of participants.The higher the PASE score, the higher the activity level.Results:In terms of physical activity concerning housework and labor and total PASE scores, there were statistically significant differences between those living alone and those not living alone[50.00(35.00)points vs.80.00(55.00)points, 85.80(67.23)points vs.110.80(75.18)points, Z=1.984, 2.102, P=0.047, 0.036]. After adjusting for sex, age, and body mass index, binary Logistic regression analysis showed that living alone was associated with low levels of housework physical activity( OR=2.56, 95% CI: 1.26-5.07, P=0.009). Conclusions:For older adults in Shanghai communities, living alone is associated with lower physical activity levels, especially physical activity involving housework.It is necessary to promote the physical activity level and a positive attitude toward exercise for older adults living alone to maintain a satisfactory level of physical health.
