Objective To analyze the morphological alterations of corpus callosum in children with spastic cerebral palsy(SCP)using three-dimensional magnetization prepared rapid acquisition gradient echo(3D-MPRAGE)technology and to investigate the correlation between morphological indexes and gross motor function.Methods Sagittal T1WI 3D-MPRAGE data was collected from 136 children with SCP(SCP group)and 132 age-and gender-matched healthy controls(HC)(HC group),and the gross motor function measure-88(GMFM-88)was applied to assess the gross motor function.Independent sample t-test was used to compare the corpus callosum surface area,volume,maximum anterior-posterior diameter,median sagittal area(total area and area of Ⅰ-Ⅴ zone)between the two groups.Partial correlation analysis was performed to calculate the correlation between morphological indexes of the corpus callosum and GMFM-88 with age as a covariate.Results Children under 3 years old,the corpus callosum surface area of the SCP group(3 914.51 mm2±1 207.97 mm2)was lower than that of the HC group(5 725.51 mm2±1 412.66 mm2).The volume of the corpus callosum(6 108.46 mm3±2 803.97 mm3)in the SCP group was lower than that of the HC group(11 297.96 mm3±4 109.02 mm3).Also,the maximum anterior-posterior diameter of the corpus callosum in the SCP group(53.40 mm±6.31 mm)was lower than that of the HC group(57.74 mm±6.04 mm)(all P<0.05).Children over 3 years old,the corpus callosum surface area of the SCP group(4 970.06 mm2±1 191.31 mm2)was lower than that of the HC group(6 372.55 mm2±1 445.59 mm2).The volume of the corpus callosum(8 330.20 mm3±2 888.20 mm3)in the SCP group was lower than that of the HC group(13 599.82 mm3±3 429.81 mm3)(all P<0.05).Partial correlation analysis showed significant correlation between corpus callosum volume,median sagittal area and gross motor score(P<0.01)with age as a covari-ate.Conclusion The 3D-MPRAGE technology can be useful for the comprehensive assessment of morphological alterations of the corpus callosum in SCP.The corpus callosum volume,and median sagittal area may become neuroimaging references for the assess-ment of motor development in cerebral palsy(CP).

Objective:To analyze the brain functional fluctuation of benign epilepsy in children with central-temporal spikes(BECTS) by using ReHo algorithm based on the resting-state brain functional imaging, and to explore the connection of the brain function and changes of the connection pattern, so as to find the damage of the cognitive function of BECTS children in the early stage.Method:s Perspectiveness and simple random selection of 20 BECTS children and 20 healthy control children admitted to Shenzhen Children′s Hospital from January 2015 to December 2017 were conducted for basic information collection and functional magnetic resonance imaging (fMRI) testing in a resting-state.Result:s Significantly lower ReHo value appeared in the default mode network (DMN) area, and the precuneus (voxel=422, t=-5.085 6), cuneus (voxel=85, t=-4.240 3), angular gyrus (voxel=191, t=-4.681 2), cingulate cortex (voxel=313, t=-5.238 2), anterior central gyrus (voxel=12, t=-3.482 7), and supplementary motor area (voxel=1 356, t-6.596 2). The significantly increased ReHo was found in the bilateral cerebellum (voxel=71, t=5.658 2), right superior temporal gyrus (voxel=24, t= 5.184 0), operculum insulae (voxel=337, t=6.814 9), left parietal lobe (voxel=12, t=4.378 7), and inferior parietal lobule (voxel=11, t=3.433 7). Conclusions:Significant impairment of DMN, Wernicke and angular gyrus functions in BECTS children may be one of the mechanisms of cognitive dysfunction.Enhanced sensorimotor area and cortical brain functions near the operculum insulae and central sulcus lead to seizures with typical clinical symptoms.fMRI has a high specificity and sensitivity for evaluating the brain function of children with BECTS, and it can detect the impairment of cognitive function in children with this type of epilepsy at an early stage.

Objective To investigate the effect of meridian point cosmetic therapy of traditional Chinese medicine(TCM)on acne.Methods 80 cases of acne patients were selected and divided into the treatment group(50 cases)and the control group(30 cases).The treatment group was given medication by differentiation of symptoms and signs and designed a complete treatment scheme by the demonstration of health analysis curve through test by balanced cosmetic equipment and meridian point of TCM.The control group only received extravenous medication.The effect of the two groups was observed after 2 months' treatment.Results The total effeetive rate in the treatment group was 94.0%,which was superior to that of the control group(73.3%),x2=11.08,P＜0.05. Conclusion Application of meridian point cosmetic therapy of TCM could facilitated the diagnosis and treatment by differentiation of symptoms and signs and thus improve the curing rate.
