ObjectiveTo explore the correlation between gross motor function and intelligence in school-age children with cerebral palsy. Methods93 school-age children with cerebral palsy were assessed with Gross Motor Function Classification System (GMFCS), Wechsler Intelligence Scale for Children (WISC) and Children Adaptive Behavior Scale (CABS). ResultsThe classification of GMFCS did not correlated with intelligence quotient （r=0.184,P>0.05), nor the adaptive behavior （r=0.056,P>0.05）. ConclusionThere is no correlation between gross motor function and intelligence in school-age children with cerebral palsy.

Objective To investigate subtle structural changes of white matter in patients with amnestic mild cognitive impair-ment (aMCI)using a tractography-based method.Methods Thirty patients with clinical diagnosis of aMCI and thirty-one cases of normal control(NC)and undergone diffusion tensor imaging.Cingulum (CG),corpus callosum (CC),uncinate fasciculus (UNC) and inferior occipitofrontal fasciculus (IOFF)were reconstructed,and fractional anisotrophy (FA)values were measured along these tracts using dTV II software.Differences of white matter tracts’FA values were explored between aMCI group and NC group.In addition,correlation analyses were also done between FA values and the MMSE(mini-mental state examination)scores in the aMCI patients.Results ① aMCI patients exhibited significant lower FA values in the bilateral CG,bilateral UNC and CC than NC group. Although there were no statistically significant differences,aMCI patients exhibited lower FA values than NC group in the left IOFF.② The FA values of right CG were positively correlated with MMSE scores.Conclusion Abnormal changes of FA values in CG,UNC and CC of aMCI patients suggest that subtle damages of white matter tracts related to memory exist in the prodromal phase of Alzheimer’s disease (AD).Fiber tractography has high sensitivity in detecting early damages of white matter.

Objective To apply Canadian Occupational Performance Measure (COPM) on the patients injured in Sichuan Earthquake. Methods COPM was applied to evaluate 51 patients in hospital before and 1 months after treatment. The first evaluation confirmed the problems on occupational activities for them. Then the plan was made to solve the problems. The second evaluation was to assess the effect of the treatment.Results The problem of self-care activity is more than that of productive activities and leisure activities(P<0.01). Total scores of performance of occupational activity and satisfaction improved(P<0.01, P<0.01)Conclusion COPM is helpful to confirm the problems of occupational activities and contribute to develope the primary goals for rehabilitation and treatment programs.

This study was designed to investigate the effect of dihydromyricetin (DHM) on inducing apoptosis of ovarian cancer cells A2780 through endoplasmic reticulum stress (ERS) pathway and the mechanisms involved in vitro and in vivo. A2780 cells were treated with different concentrations of DHM, and the protein expression levels of glucose-regulated protein 78 (GRP78) which is related to ERS increased, apoptotic proteins C/EBP-homologous protein (CHOP), and cysteinyl aspartate specific proteinase-12 (caspase-12) elevated. After pretreatment with ERS inhibitor, 4-phenyl butyric acid (4-PBA), following the intervention with DHM, the A2780 cell viability decreased and apoptotic rate increased. All animal welfare and experimental procedures were approved by the Animal Ethics Committee of Chongqing Medical University. Intraperitoneal injection of DHM suspension into nude mice with ovarian cancer could significantly inhibit the growth of transplanted tumor in vivo, increase the protein expression levels of GRP78, CHOP, and caspase-3. Moreover, swollen and broken endoplasmic reticulum could be observed in tumor tissues, suggesting that DHM intervention induces apoptosis mediated by ERS. The results indicated that DHM could induce apoptosis of ovarian cancer cells and inhibit the growth of transplanted tumors in nude mice, which might be related to the activation of ERS pathway.
