Objective:To examine postural control between normal and attention deficit hyperactivity disorder(ADHD)boys,and compare the development characters.Methods:In the study,146 ADHD boys and 84 normal boys participated,ages being between 7 and 12 years.Balance Master was used to assess posture control.Posture stabilities were tested under 4 different conditions(firm surface with eyes open,firm surface with eyes closed,foam pad with eyes open,foam pad with eyes closed).We tested three times for one condition,20 s per time.The mean sway velocity was recorded.Results:(1)Normal boys:In firm surface with eyes open,analyses of variance between normal boys revealed no significant differences between different age groups,and the 11-and 12-year-old group did not achieve scores comparable to the adult(t=6.145,P

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 investigate the role of M3 receptor in the effect of penehyclidine hydrochloride(PHC) upregulating β-arrestin-1 expression in lipopolysaccharide(LPS)-induced human pulmonary microvascular endothelial cell(HPMVEC) injury.Methods.M3 shRNA transfected HPMVEC and normal HPMVEC cells were randomly divided into LPS group(A),LPS+pHC group(B),LPS+ M3 shRNA transfection group(C) and PHC+ LPS+ M3 shRNA transfection group(D).The cytoskeleton change was observed by laser scanning confocal.The LDH level in cellular supernate was detected.The VCAM 1 protein expression was examined by immunofluorescence chemistry.β-arrestin-1 protein expression was determined by Western blot and β-arrestin-1mRNA expression was measured by real-time PCR.Results Compared with the group A or C,F-actin cytoskeleton arrangement in the group B or D was neat,the LDH level and VCAM-1 protein expression were decreased,and β-arrestin-1 expression was increased;compared with group A or B,F-actin cytoskeleton arrangement in the group C or D was neat,the LDH level and VCAM-1 protein expression were decreased,while the β-arrestin-1 expression had no obvious change.Conclusion Silence M3 receptor is conducive to reduce LPS-induced HPMVEC injury.But the role of PHC up-regulating β-arrestin-1 expression has no necessary connection with M3 receptor.

Objective To investigate the expression level of serum miR-193a-3p,miR-337-5p and miR-483-5p in esophageal squamous cell carcinoma (ESCC) patients and to explore their value for diagnosis and prognosis of ESCC.Methods Serum samples were collected from 63 ESCC patients before and after surgery in Nanjing General Hospital and Xuzhou Cancer Hospital between June 2013 and May 2014 and serum sanples of 63 age-and sex-matched healthy individuals acted as the normal controls.TaqMan Low Density Assay was used to detect the deregulated miRNA in ESCC patients and then quantitative real-time PCR was used to validate the upregulated miRNA miR-193a-3p,miR-337-5p and previously reported miR483-5p that was upregulated in oral squamous cell carcinoma (OSCC).Finally,the three miRNA were evaluated for their clinical value in the diagnosis and predicting prognosis of ESCC.Results Compared with normal controls,serum levels of miR193a-3p,miR-337-5p and miR-483-5p in ESCC patients were significantly up-regulated (0.459±0.339 vs 0.195±0.084,U =591;5.686±5.211 vs 2.476±0.808,U=605;32.545 ± 22.479 vs 19.509±10.601,U=1 037,respectively,all P＜ 0.0001) and their levels were significantly reduced after the surgical treatment (P＜0.05).The areas under the ROC curve of serum miR-193a-3p,miR-337-5p,miR-483-5p and miR-Panel were all larger than that of CEA.Univariate Kaplan-Meier analysis revealed that ESCC patients with low expression level of miR-483-5p in postoperative serum exhibited higher survival rate than those with high level(P=0.022).Conclusion Serum miR-193a-3p,miR-337-5p and miR-483-5p can be potential molecular biomarkers in the diagnosis and predicting prognosis of ESCC.

Obesity has a harmful impact on health and is imposed by both environmental and genetic factors. Recently, over 60 obesity-related susceptible loci have been identified through genome-wide association study. However, it still remained unknown whether these loci were specific or generalized to the ethnic groups for genetic distinction. This review summarized the obesity-related susceptible loci in Asian populations, which were recently identified among Europeans or Asians.
