ObjectiveTo investigate the clinical feature, prognosis and prognostic factors of early post-traumatic seizures in children. MethodsRetrospective review was performed on 101 individuals with early post-traumatic seizures (EPTS) who were diagnosed in Department of Neurosurgery in Children's Hospital of Chongqing Medical University from January 2008 to June 2013. The record was collected, which included patient's demographics, clinical and radiological presentation, management, and follow-up results of 12 months. The individuals were divided into late post-traumatic seizures (LPTS) group and control group according to the occurrence of LPTS or not. The SAS 9.2 was used for statistical analysis. ResultsDuring 101 cases in our study, male accounted for 60.4%, female accounted for 39.6%, and the ratio was 1.5 to 1. The percentage of patients who were under 6 years old was 74.3%, and the number of cases decreased with age. The peak time of EPTS was within 24 hours after traumatic brain injury. 55.4% of EPTS was the generalized seizures, 34.7% was the partial seizures, and 9.9% was the partial seizures and evolved to secondarily generalized seizures. The incidence of LPTS observed in our study was 26.7% within 12 months follow-up. The electroencephalogram displayed epileptiform discharges in 3 individuals who were without epileptic seizures. There was statistically significant difference in group LPTS compared to control group on these factors which included GSC score≤8(P=0.0064), complicated necrencephalus and/or encephalatrophy(P < 0.0001), multiple brain injuries(P=0.0210), subdural hemorrhage(P=0.0151) and intracranial operation(P=0.0029). The age, history, epileptic seizure type of EPTS, brain contusion, skull fracture and the early use of antiepileptic drugs (AEDs) had no statistically significant difference between LPTS group and control group(P > 0.05). ConclusionsEPTS is prone to occur in children under 6 years old. Male is obviously more than female, and the ratio is 1.5:1. The peak time of EPTS is within 24 hours after traumatic brain injury and most of EPTS are generalized seizures. The incidence of LPTS in children with EPTS exceeds those previously reported. Periodical electroencephalogram examination is essential to decrease the missed diagnosis of LPTS. The GSC score≤8 and complicated necrencephalus and/or encephalatrophy will dramaticlly increase the risk of LPTS. Multiple brain injuries, subdural hemorrhage and intracranial operation are also risk factors for the prognosis of EPTS. Although the use of AEDs is unable to decrease the incidence of LPTS after 12 months follow-up, it is probably beneficial to improving the cognition and brain development. The controversial finding in our study is whether intracranial operation can influence the prognosis of EPTS or not.

Objective To review the current status and advances of the correlation between traumatic brain injury (TBI) and fracture healing. Methods The related domestic and abroad literature about the correlation between TBI and fracture healing was extensively reviewed and analyzed. Results There are a variety of studies on the correlation between TBI and fracture healing, which can be divided into two major aspects: revascularization and osteogenesis; the local and systemic changes of the neuropeptide and hormone after TBI. Conclusion TBI facilitates callus formation, the further research is needed to clarify the exact mechanism.

Objective To explore the number variation trend of inpatients with traumatic brain injury (TBI) in high altitude and plain areas. Methods The first page information in medical records of TBI patients, who were admitted to military hospitals from 2001 to 2007, was searched and extracted from the Chinese Trauma Database. Two military hospitals in high altitude area and another two in the same hospital level in plain area were selected. Then, the number variation trend of TBI inpatients in those two areas was compared. Results In high altitude area, the proportion of male patients and their median inpatient days were higher, while the age, proportion of Han patients and surgery rate were lower than those in plain area (all Plt;0.001). During 2001-2007, there were 9 141 TBI patients discharged from the four hospitals, and the average annual growth rate was 13.15%. In high altitude area, the average annual growth rate of discharged inpatients was 24.00%, while in plain area, it was just 7.09%. The 4 common categories of TBI were intracranial injury, open wound of the head, neck and trunk, skull fracture, and other injuries. Conclusion Compared with the plain area, there are significant differences in the demographics, hospital stay and surgery of inpatients in high altitude area. The average annual growth rate of TBI inpatients discharged from hospitals in high altitude area is faster than that in plain area, to which should be paid attention by relevant departments.
Objective To investigate the changes in the expression level of bone morphogenetic protein 2 (BMP2) in the bone callus of rats with femoral fracture and brain injury to explore the effect of the brain injury on the fracture healing and to explore the related mechanism. Methods Thirty-two 12 week old SD rats weighing 368±25 g were randomly divided into 4 groups of 8 rats in each. The rats in Group A had a femoral fracture and a brain injury for 1 week; the rats in Group B had a femoral fracture but without brain injury for 1 week; the rats in Group C had a fracture and a brain injury for 2 weeks; and the rats in Group D had a fracture but without brain injury for 2 weeks. Thus, Groups A and C were used as the femoral fracture and brain injury models, and Groups B and D as the pure femoral fracture models for the controlled study. After the X-ray films were taken, the bone callus was obtained 1 week and 2 weeks after operation, respectively. Then, the bone callus growth and its histology were examined with theHE staining, the expression and changes in the level of BMP-2 were examined with the immunohistochemical staining, and the level of BMP-2 mRNA was measured with the RT-PCR. Results The X-ray films showed that less bone callus formation was found in Group A, and the fracture line in Group B was clearer than that in Group A. There was a greater amount of callus in Group C, and the fracture line was blurred. Only a little bone callus formation was found in Group D. The HE staining indicated that more fibroblasts and early-stage chondrocytes were found in Group A; some fibroblasts in the fracture interspace and fewer early-stage chondrocytes in Group B; some newly-formed trabecular bone at the end of the fracture in Group C; but no trabecular bone formation in Group D. The immunohistochemical staining indicated that the positive expression of BMP2 was b in the cytoplasms of the fibroblasts, the mesenchymal cells, the vascular endothelial cells, the early-stage chondrocytes, and the osteoblasts. The number of the positive cells was greater in Group A than in Group B, with a higher color intensity. The number of the positive cells was greater in Group C than in Group D, with a higher color intensity. The percentages of the cells positive for BMP-2 in the callus were greater in Groups A and C (0.762%±0.052%，0.756%±0.079%)than in Groups B and D (0.702%±0.052%，0.672%±0.044%) at the same time point, ith a statistically significant difference (Plt;0.05). The RT-PCR analysis showed that the expression of BMP-2 mRNA in the callus in Groups A-D was decreased in sequence. There was a significantly higher level of the expression in Groups A and C(1.07±0.13，0.78±0.11) than in Groups B and D(0.91±0.12，0.61±0.08) at the same time point (Plt;0.05). Conclusion The brain injury can promote the fracture healing process, which is probably related to an increase in the expression level of BMP-2 after the brain injury.
