Objective To investigate the distribution of complications and the relationship with neurologic subtype and gross motor function in preterm infants with cerebral palsy (CP). Methods The type, grade of Gross Motor Function Classification System (GMFCS), intelligence,speech, ophthalmologic consultation, brainstem auditory evoked potential and electroencephalogram of 135 preterm infants with CP were reviewed. Results There were 284 complications in total, (2.10±1.33) per child, and was significantly different among various types of CP (F=5.50, P<0.001). The incidence of mental retardation and speech disorder was significant different among various types (P<0.05). The incidence of mental retardation, speech disorder, visual impairment and epilepsy increased significantly (P<0.05) in spastic quadriplegia infants,compared with those with diplegia and hemiplegia. The incidence of mental retardation, speech disorder, visual impairment and musculoskeletal disorder was significantly different (P<0.05) among various grades of GMFCS. The frequency of complications was more in children unable to walk (GMFCS Ⅳ~Ⅴ) than able to walk (GMFCS Ⅰ~Ⅲ) for children over 2 years old (t=70.05, P<0.001). Conclusion The incidence of mental retardation, speech disorder, visual and hearing impairment, secondary musculoskeletal disorder and the multiple disorders are related with neurologic subtype and/or the grade of GMFCS.

Objective To analyze the expression of glial fibrillary acidic protein(GFAP) in hippocampal of rats with hypoxic-ischemic brain damage(HIBD) after injection of bone marrow stromal cells(BMSCs) supernatant into the lateral ventricle of the neonate rats,assess the ability of learning and memory,and explore the mechanism.Methods 7-day-old SD rats were randomly divided into sham operation group,model group,cells and supernatant group,with 20 rats in each group.The HIBD model was established via the ligation of left carotid arteries followed by 2-hour hypoxia.One week later,rats in control group were injected with 0.01 mol/L PBS 2 μl via the left ventricle.Meanwhile,the cell and the supernatant groups were injected with BMSCs and supernatant harvested from BMSC culture,respectively,via the same route.In the sham operation group,the left carotid arteries were separated but not ligated,and no hypoxia treatment was imposed on this group.They also received 0.01 mol/L PBS injection 2 μl per weak post surgery.8 weeks later,Morris water maze test was performed to assess the learning and memory,and the expression of GFAP in the dentate gyrus of rats was measured by immunohistochemistry.Results Morris water maze showed that the searching time of the probe trail(T1:(15.40±2.80) s) and reversal probe trail (T2:(16.45± 1.16) s) of the model group was shorter than that of the sham operation group (T1:(19.96±2.57) s,T2:(2:25.32±2.54)s,P＜0.05),while the searching time of the cell group(T1:(17.54± 1.80)s,T2:(18.99± 1.47) s) and supernatant group (T1:(17.40±2.37) s,T2:(17.96± 1.09) s) was prolonged compared with that of the model group (P＜0.05).No significant difference between the cell group and the supernatant group (P＞0.05).The integral optical density (IOD) value of GFAP positive cells was higher in the model group than that in the sham operation group(15.26±1.49 vs 12.82±2.56,P＜0.05),while the IOD of cell group(18.13±1.97) and that of the supernatant group(17.38± 1.64) were higher than that of the model group (P＜0.05).However,there was no significant difference between the cell group and the supernatant group (9＞0.05).Conclusion BMSC supernatant injected through lateral ventricle can improve the HIBD rats' abilities of learning and memory.The mechanism might be that MSCs secrete some cytokines to promote central nervous system repair.

Objectives To investigate the closing time of patent foramen ovale in newborns and infants in order to provide appropriate follow-up time points.Methods From September 1,2010 to April 30,2011,131 of l 202 full-term infants with patent foramen ovale were finished follow up at 3,6 and 12 months of age in Beijing Children's Hospital,Capital Medical University.If the foramen ovale was not closed at 12 months of age,the patients were followed up until two years of age.The closing time and the effects of complicated patent ductus arteriosus (PDA) were analyzed statistically using two independent t test,Chi-square and trend Chi square tests.Results Of the 131 full-term infants with patent foramen ovale,72 were males,and 59 were females.The foramen ovale size in neonatal period was not statistically different between males and females [(2.94 ±0.86) vs (2.95 ± 0.92) mm,t=0.641,P=0.964].The foramen ovale closing rate at 3 months was 21.4％ (28/131),67.9％ (89/131) at 6 months,and 95.4％ (125/131) at 12 months.The rate of foramen ovale closing decreased with larger foramen ovale at 3,6 and 12 months of age (x2trend were 42.930,101.050 and 63.260,all P＜0.05).Six patients with patent foramen ovale at 12 months of age were followed up until 2 years of age:two cases with foramen ovale ＜5.0 mm in the neonatal period were closed,one of two cases with foramen ovale ≥5.0 but ＜6.0 mm was closed,and one of two cases with foramen ovale ≥ 6.0 mm was closed.Of the 131 cases,121 were simple patent foramen ovale,and l0 were complicated with PDA.There were no significant difference in neonatal foramen ovale size between children with simple patent foramen ovale and those with PDA [(2.95 ±0.88) vs (2.82±0.83) mm,t=0.782,P=0.649].The closing rates in the simple patent foramen ovale group at 3,6,and 12 months of age were 21.5％ (26/121),57.9％ (55/95) and 87.5％ (35/40),respectively,and showed no significant difference from those with PDA (2/10,6/8 and 1/2,x2=0.012,0.946 and 1.536,all P＞0.05).In the simple patent foramen ovale group,the closing rate at 3 months was less than that at 6 months and 12 months 0x2 were 10.410 and 62.515,both P＜0.01).There was no difference in the closing rate in patients with PDA at 3,6 and 12 months (x2=5.748,P＞0.05).Conclusions Asymptomatic patent foramen ovale with a foramen ovale ＜5.0 mm may not require follow-up.But patients with a foramen ovale ≥ 5.0 mm,even asymptomatic,should be followed up using thoracic echocardiography at 2 years,and further follow-up is required if unclosed.

To investigate the curative effect of minimally invasive sclera buckling on single retinal detachment.METHODS:Totally, 100 cases of patients with retinal detachment ( 106 eyes ) enrolled in our hospital were randomly divided into observation group and control group, 53 eyes in each group. Patients in observation group were treated with minimally invasive sclera buckling, while patients in control group received traditional limbal conjunctival incision. After surgery, patients were all followed up for 6 ~18mo, during which the retinal recurrence situation, degree of vision enhancement and compliance occurrence rate was recorded. RESULTS: The retinal reattachment rate once of observation group (96. 22%) was significantly higher than that of control group (88. 68%), there was statistically significance (P<0. 05). The vision enhancement rate of observation group (84. 90%) was significantly higher than that of control group (71. 70%), there was statistically significance (P<0. 05). The compliance occurrence rate of observation group (11. 32%) was significantly lower than that of control group (32. 08%), there was statistically significance (P<0. 05).CONCLUSlON: The improved minimally invasive sclera buckling can significantly enhance the curative effect for retinal detachment, decrease the compliance occurrence rate, improve vision function, and is a scientific, practical and rigorous tool for retinal detachment treatment.
