Objective:To investigate the application value of small private online course (SPOC) based on the concept of outcomes-based education (OBE) in rehabilitation nursing training for elderly patients after lumbar surgery.Methods:A total of 46 clinical nurses in Department of Spinal Surgery in our hospital were selected as subjects, and they were divided into control group and observation group using a simple random number table, with 23 nurses in each group. The nurses in the control group were trained by the traditional teaching method, while those in the observation group were trained by SPOC teaching based on the educational concept of OBE. The two groups were assessed in terms of the effect of training, professional core competencies, and degree of satisfaction with the training mode. SPSS 22.0 was used to perform the chi-square test and the t-test. Results:Compared with the control group, the observation group had significantly better overall evaluation [（89.52±5.07）vs.（86.48±4.13）], mastery of practical operation skills (91.30% vs. 65.22%), and proficiency in the operation of commonly used clinical instruments (95.65% vs. 80.95%)( P<0.05). The observation group had a significantly better score of the professional core competence scale than the control group ( P<0.05). Compared with the control group, the observation group had a significantly higher degree of satisfaction with the training ( P<0.05). Conclusion:In rehabilitation nursing training for elderly patients after lumbar surgery, SPOC teaching based on the educational concept of OBE can improve the training effect of clinical nurses, enhance their professional core abilities, and increase the degree of satisfaction with training.

Objective@#The purpose of this study is to understand associations of developmental coordination disorders (DCD) and sensory integration disorders (SID) with family environment for motor development.@*Methods@#A questionnaire survey was conducted among 309 parents of 3-4 years old children in two kindergartens in Beijing selected by clustering sampling, using Development Coordination Disorder Questionnaire, Sensory Integrative Function Scale and Family Environment Scale on Motor Development for Urban Preschool Children.@*Results@#Among the 309 children, the prevalence of DCD was 8.1% with gender difference with boys(11.0%) significantly higher than girls(4.4%)(χ2=6.71，P<0.05). The rate of SID was 42.1% with no significant gender difference(χ2=7.32，P=0.62). The concordance rate of SID and DCD(23/25，92.0%) was related to family environment for motor development. Specifically, parental rearing patterns was the primary factor for co-occurrence of SID and DCD(B=-0.37, OR=0.69, 95%CI=0.54-0.89，P<0.01).@*Conclusion@#The development of SID and DCD is closely related among preschoolers. Parental rearing pattern plays an important role in SID and DCD.

Objective To investigate the value of high-resolution magnetic resonance imaging (HR-MRI) of arterial walls in the diagnosis of cerebral artery dissection (CAD).Methods The patients diagnosed as CAD and completed computed tomography angiography (CTA),magnetic resonance angiography (MRA),digital subtraction angiography (DSA),and HR-MRI were enrolled retrospectively.The detection rate and diagnostic value of the 4 imaging techniques were compared and analyzed.Results A total of 15 patients were enrolled,5 had internal carotid artery dissection,7 had vertebral artery dissection,2 had middle cerebral artery dissection,and 1 had basilar artery dissection.HR-MRI revealed 11 intramural hematoma,9 intimal flap,3 double lumen sign,and 2 pseudoaneurysm.A total of 18 CADs were detected in 15 patients,17 (94.44％),14 (77.78％),5 (27.78％) and 6 (33.33％) were detected with HR-MRI,DSA,CTA and MRA,respectively.There were significant difference in CAD detection rates of HR-MRI,DSA,CTA and MRA (x2 =24.939,P ＜ 0.001).The CAD detection rate of HR-MRI and DSA were significantly higher than those of CTA and MRA (all P ＜ 0.01 for HR-MRI,all P ＜ 0.05 for DSA),but there was no significant difference in CAD detection rate between HR-MRI and DSA.Conclusion HR-MRI is a diagnostic method for CAD with higher sensitivity.

Objective To investigate the metabolic changes and the metabolites distribution of different hippocampal regions (head,body and tail)in patients with Alzheimer’s disease (AD)using 1 H-MRS for early diagnosis.Methods The hippocampal multivoxel 1H-MRS at 3.0 T was scanned in 30 patients with AD and other 30 normal cognitive elders (NC)as contrast.The data obtained were processed at a workstation.The hippocampus was divided into 3 parts (head,body and tail),and the ratios of N-acetylaspartate (NAA)/creatine (Cr),myoinositol (MI)/Cr and MI/NAA were calculated respectively.The metabolite ratios and distribution changes were compared between group AD and NC.Results Compared with the group NC,the NAA/Cr in group AD in bilateral hippocampal body and tail was decreased,whereas the MI/Cr and MI/NAA in bilateral body and tail,MI/NAA in left head were opposite (P0.05).Conclusion Metabolic changes and disappearance of the normal distribution in different hippocampal regions detected by 1 H-MRS provide helpful clues for early diagnosis of the AD.

Objective To analyze the patterns of cortical atrophy of the two subtypes of frontotemporal lobar degeneration (FTLD ),behavioural-vsriant frontotemporal dementia (bvFTD ) and primary progressive aphasia (PPA).And to compare them with that of Alzheimer disease (AD) to provide an objective basis for early diagnosis and differential diagnosis.MethodsA total of 83 patients were enrolled in this study and there were 30 patients with cognitively normal controls (CN),30 with AD and 23 with FTLD (10 with bvFTD,13 with PPA).Philips 3.0 T TX scanner and 8 channel head coil was employed.Three dimensional turbo fast echo(3D-TFE)T1WI sequence with high resolution was used to collect the volume data of gray matter.3D-TFE T1 WI images were normalized and segmented into gray matter map for statistical analysis by SPM 8 and VBM 8.The false discovery rate (FDR) was adopted in P value adjustment,P ＜ 0.001,and the cluster size was set at 5.The full width at half maximum (FWHM ) was set at 4 mm for the smoothing.Paired t test was used for statistics.ResultsIn bvFTD,PPA and AD groups,there were diffuse regions with reduced volume in cerebral cortex and subcortical structures (such as the hippocampus,the amygdala,the caudate nuclei,et al).The most obvious atrophic region in bvFTD and PPA group was found in the frontotemporal.Compared with AD,gray matter atrophy in bvFTD was found in brain regions including bilateral temporal lobes,bilateral superior temporal pole gyri,bilateral middle temporal pole gyri,right fusiform gyrus and bilateral frontal lobes.Among them,temporal and frontal lobes atrophy had obvious right partial lateralizing,with 14 301 voxels in right temporal lobe and 5105 in left (t =-5.03,P＜0.05).The number of atrophy voxels in right and left frontal lobe were 1344 and 125 (t =3.45,P ＜0.05).The left temporooccipital lobe atrophy was more obvious than the right in PPA,with 15 637 voxels in left and 10 723 in right ( t =- 2.65,P ＜ 0.05 ).ConclusionsThere are different brain gray matter atrophy patterns in bvFD,PPA and AD.Among them,bvFTD has asymmetric right frontal and temporal lobe atrophy,which may be related to characteristic personality changes.On the other hand,the asymmetric atrophy in left temporooccipital lobe may be responsible for the aphasis of patients with PPA.
