Attention deficit hyperactivity disorder(ADHD) and developmental coordination disorder(DCD) are both childhood disorders identified in the DSM-Ⅳ.Studies investigating ADHD have found that around half of ADHD cases also have motor problems severe enough to be diagnosed as DCD.Further,children initially diagnosed as DCD have also been found to meet moderate to severe diagnosis for ADHD.Both disorders have been linked to a lot of psychosocial problems.Furthermore,when ADHD and DCD are co-morbid,the outcome tends to be more severe than when either disorder occurs alone.In the past decade,many studies identified shown that ADHD children experienced difficulties with both fine motor movements and gross motor movements.Notably,most of these foregoing studies found balance functions of ADHD were impaired.In order to maintain balance under a verity of environmental conditions,sensory information from somatosensory,visual,and vestibular origins must be integrated by the central nervous system.But there are rich evidences suggesting that children with ADHD can not organize the motor information effectively.The maintenance and control of posture and balance,whether in static or dynamic conditions,are essential requirements for daily activity.The balance function has been closely associated not only with both gross motor movements,such as sitting,standing,walking and fine motor movements,but also with human behaviors.There are increasing evidences suggesting that balance deficit correlates with symptoms of ADHD.Therefore,motor coordination difficulties co-occurring with ADHD should be given emphasis in clinical practice;the training of balance may be one of the possible methods to improve the motor coordination function in ADHD children.

Objective:To explore the effect of methylphenidate on the balance function of children with attention deficit hyperactivity disorder,and the correlation between the variations of balance function and subjective clinical assessment before and after treatment.Methods:From July to December 2006,23 children(19 boys and 4 girls) who met DSM-Ⅳ criteria for ADHD participated in an open study conducted at Institute of Mental Health,Peking University.The variation of their balance functions before and after methylphenidate extended-release tablets(OROS methylphenidate) treatment were evaluated,and the differences of balance functions between 19 ADHD boys pre-and post-treatment and 38 age-matched typically developing control boys were compared.Balance functions were assessed with sensory organization test(SOT) provided by SMART EquiTest system.Subjective clinical assessments were measured with ADHD rating scale-Ⅳ and IOWA Conners rating scale.Results:The equilibrium score(ES) in SOT5,SOT6,and composite score (61.84?14.19,65.88?15.41,and 75.70?10.30,respectively),and the strategy score(SS) in SOT4 and SOT5(89.20?3.17 and 83.22?6.56),and the sensory analysis of vestibular ratio(67.64?14.43) improved significantly after OROS methylphenidate treatment compared to those before treatment(49.81?16.26,57.61?16.72,68.70?11.96,86.84?4.49,78.55?6.55,and 54.46?17.27,respectively,P0.05). Conclusion:This study suggests that methylphenidate can improve the balance function of children with ADHD through direct effect on the balance system.

Objective:To investigate whether the likelihood of balance impairment in children with attention deficit hyperactivity disorder(ADHD) increases with the presence of disruptive behavior disorder(DBD),and whether the likelihood of co-occurring diagnosis of DBD increases in ADHD children with severer balance deficit.Methods:Three groups of 20 children each,representing pure ADHD,ADHD+DBD,and typically developing control children,were included and group matched by age and gender.Balance functions were assessed with the Balance Master in different conditions.We compared the percentages of children in each group who swayed faster than 85% of the typical control children in all conditions.Results:In the conditions of firm surface with eyes open(FI/EO) and eyes closed(FI/EC),and foam surface with eyes open(FO/EO) and eyes closed(FO/EC),the sway velocities of ADHD only group(0.65?0.26 ?/s,0.65?0.30 ?/s,0.95?0.29 ?/s,and 1.70?0.49?/s,respectively) were significantly higher than those of the typical control group(0.47?0.18 ?/s,0.43?0.19 ?/s,0.76?0.21 ?/s,and 1.27?0.38 ?/s,respectively)(P

Mesenchymal stem cells (MSCs) have a strong self-renewal capacity and multi-differentiation potential,which make them become ideal seed cells of tissue repair and target cells of gene therapy.However,the labeling and tracing method of MSCs transplanted in vivo is the hot spot and difficult problem of the current research.At present,the commonly used tracer methods of MSCs include fluorescence dye labeling,molecular marker,imaging marker technology.This paper summarized the advantages and disadvantages of these tracer methods.

Objective To evaluate the correlation of the diagnostic chance of maternal pulmonary tuberculosis and the prognosis of their children. Methods One hundred and fifty-six patients with maternal pulmonary tuberculosis were analyzed,which were assigned to two groups based on the diagnostic chance: pregnant group ( 60 cases) and postpartum group ( 96 cases). Living quality of their children was counted, and viewed in parallel with children (98 cases,control group) of healthy mother at the same time. Results The morbidity in postpartum group was 69.79% (67/96),significantly higher than that in pregnant group [l3.33%(8/60)](P<0.05) and control group [4.08%(4/98)](P<0.05). The mortality in postpartum group was 8.33% (8/96), significantly higher than that in pregnant group (0)(P< 0.05) and control group (0)(P< 0.05).The morbidity and mortality in pregnant group were not significant difference compared with control group(P > 0.05 ). Conclusion Diagnosis and treatment before the parturition of maternal pulmonary tuberculosis can reduce the morbidity and mortality of the children and improve their life quality.
