Objective To analyze the MRI features of Hirayama disease(HD)with cervical natural position and its diagnostic val-ue.Methods The natural position of cervical vertebra with MRI examination was used in 1 5 patients and 40 normal people.The spe-cificity and sensitivity of MRI features were analyzed and the ratio of cervical sagittal diameter/cervical transverse diameter (CSD/CTD)of the lower cervical cord was measured.Results CSD/CTD of the patients and control group had a significant difference (t=7.99,P =0.00).The sensitivity of LOA was 86.7%,and its specificity was 88.4%.The sensitivity of atrophy of the lower cervical cord was 80.0%,and its specificity was 79.5%.The sensitivity of the cervical spine curvature abnormalities was 40.0%,and its spe-cificity was 65.2%.The sensitivity of abnormal signal in the spinal cord was 46.7%,and its specificity was 87.5%.The sensitivity of abnormal signal in the epidural outer cavity was 20.0%,and its specificity was 96.8%.Conclusion MRI features of lower cervical cord in combination with clinical symptoms and signs can be helpful for the accurate diagnosis of HD.

Objective To observe the effect of ultra-low frequency transcranial magnetic stimulation on cerebral blood flow in children with spastic diplegia cerebral palsy. Methods 36 cases of spastic diplegia cerebral palsy were divided into control group (n=21) and obsevation group (n=15), 19 healthy children were as normal group. The control group received conventional rehabilitation training. The obsevation group received the ultra-low frequency transcranial magnetic stimulation in addition. All the children received the check of transcranial color Doppler (TCD). Results Several arterials flow velocity was lower, several arterials pulsatility index and resistance index were higher in the obsevation group than in the normal group before treatment (P<0.05). Compared with the control group, the arterial flow of obsevation group improved, pulsatility index and resistance index decreased in some degrees in the obsevation group after treatment (P<0.05). Conclusion The cerebral blood flow is of low velocity and high resistance in spastic diplegia children, while ultra-low frequency magnetic stimulation could improve the condition of cerebral flow.

Objective To study the agreement of the two kinds of assessment for neurological development, the Qualitative Assessment of General Movements (GMs) and the 52 Items Neurological Assessment from Birth to 1 Year, in preterm infants during the early infantile period. Methods16 preterm infants with or without risk factors for brain injury were assessed with GMs and the 52 Items Neurological Assessment from Birth to 1 Year within 3 months after birth. ResultsFor the GMs, 11 infants were assessed as normal, 4 as poor repertoire (PR) and 1 as cramped synchronized (CS). For the 52 Items Neurological Assessment from Birth to 1 Year, 12 infants were normal, 4 were moderate abnormal. Kappa=0.709.ConclusionThe result of GMs agrees with that of 52 Items Neurological Assessment from Birth to 1 Year for preterm infants during the early infantile period.

Objective To observe the effect of forearm crutches on motor function of children with spastic cerebral palsy. Methods 60 children with spastic cerebral palsy were divided into observation group (n=30) and control group (n=30). The control group accepted rou-tine rehabilitation, while the observation group were also trained to use forearm crutches. They were assessed with Gross Motor Function Measure-88 (GMFM-88) and Balancer. The way of item 70 of GMFM-88 was used to assess the mobile capability. Results The scores of GMFM-88 significantly improved in both groups after treatment (t>6.002, P<0.001), and improved more in the observation group than in the control group (t=2.317, P<0.05). The whole path length and the circumference area reduced in both groups after treatment (P<0.05), and reduced more in the observation group with the assist of the forearm crutches (P<0.01). The incidence of walking was more in the observa-tion group with the assistant of the forearm crutches (χ2=25.87, P<0.01). Conclusion Forearm crutches assistant can improve the recovery of motor function, balance and walking ability in children with spastic cerebral palsy.

Objective To investigate the long-term effect of Botulinum toxin type A (BTX-A) block on spasticity in cerebral palsy. Methods From June, 2005 to December, 2013, 51 children with spastic cerebral palsy accepted routine rehabilitation with (trial group, n=24) or without (control group, n=27) BTX-A block. They were assessed with modified Ashworth Scale (MAS), Physician Rating Scale (PRS) and Gross Motor Function Measure (GMFM) before treatment, and with PRS and GMFM two years after treatment. Results There was no significant difference between two groups in ages, body mass, and scores of MAS, PRS and GMFM before treatment (t<1.207,χ2=0.076, P>0.05). The scores of PRS and GMFM improved in both groups two years after treatment (t>2.217, P<0.05), and improved more in the trial group than in the control group (t>2.095, P<0.05). Conclusion The long-term effect of BTX-A block is positive. The rehabilitation training after block can promote their motor function recovery.

Objective To observe the energy consumption of children with cerebral palsy before and after assisted walking. Methods From January, 2014 to October, 2015, 21 children in primary school of Grades 1~5 (control group) and 22 children with cerebral palsy in our hospital (observation group) were enrolled. They were required to walk in the 50 meters trail for six minutes. The resting heart rate, the walking distance and the heart rate after walking were measured, and the walking speed and the physical consumption index (PCI) were cal-culated. The observation group was tested with and without forearm crutches. Results Compared with the control group, the walking dis-tance and speed significantly decreased (t>10.653, P<0.001), and the PCI significantly increased (t>4.207, P<0.001) in the observation group. For the observation group without forearm crutches, the heart rate after walking, and the difference of the heart rate significantly de-creased (t=8.389, P<0.001), and the walking distance, walking speed and PCI decreased (t>2.382, P<0.05) when they walked with forearm crutches. Conclusion Assisted walking can decrease the energy consumption of children with cerebral palsy.

Objective To explore the application of gas chromatography mass spectrometry (GC/MS) in children with high risk of inher-ited metabolic disease. Methods From March, 2010 to November, 2015, 119 children suspected with inherited metabolic disease were in-cluded. The urinary organic acid was detected with GC/MS, and related diseases were screened. Results Seventeen children (14.29%) were positive with inherited metabolic disease, in which 16 cases (94.12%) manifested with development retardation. 20 children (16.81%) were probable positive. Conclusion GC/MS is effective in screening children with high risk of inherited metabolic disease, which can provide ba-sis for further diagnosis.
