Recovery of injured cingulum in a patient with traumatic brain injury

The cingulum is the neural fiber bundle that connects the basal forebrain and medial temporal lobe. The cingulum contains the medial cholinergic pathway, which originates from the basalis nucleus of Meynert in the basal forebrain. Therefore, it is important for memory function （Malykhin et al., 2008; Hong and Jang, 2010）. In the past, identification of the cingulum on conventional brain MRI has been impossible because it cannot discern the cingulum from other adjacent structures. Diffusion tensor tractography （DTT）, derived from diffusion tensor imaging （DTI）, allows three-dimensional visualization and estimation of the cingulum （Malykhin et al., 2008）.

Effect of Ventriculoperitoneal Shunt on the Recovery of Brain Function in Children with Hydrocephalus

Objective:To analyze the effect of ventriculoperitoneal shunt on the recovery of brain function in children with hydrocephalus.Methods:The clinical data of 40 children with hydrocephalus were retrospectively analyzed.Ventriculoperitoneal shunt was performed with 9003 shunt tube and P.S.Shunt tube,B.C.E.shunt tube.Electroencephalogram(EEG),and brain CT/MRI were performed before and after surgery,and postoperative follow-up was carried out to observe the therapeutic effect.Results:In this study,there were seven cases of intracranial injury,seven cases of congenital hydrocephalus,11 cases of ventricular end obstruction,three cases of abdominal end obstruction,nine cases complicated with bacterial infection,and 3 cases of shunt entering the scrotum.The prognosis of all the children was good,and there were no significant changes in eight cases.Conclusion:Ventriculoperitoneal shunt is effective in the treatment of children with hydrocephalus.

The potential of neural transplantation for brain repair and regeneration following traumatic brain injury

Traumatic brain injury is a major health problem worldwide. Currently, there is no effective treatment to improve neural structural repair and functional recovery of patients in the clinic. Cell transplantation is a potential strategy to repair and regenerate the injured brain. This review article summarized recent development in cell transplantation studies for post-traumatic brain injury brain repair with varying types of cell sources. It also discussed the potential of neural transplantation to repair/promote recovery of the injured brain following traumatic brain injury.

Effect of brain functional recovery decoction on expression of vascular endothelial growth factor and Ang-1 protein in a rat cerebral ischemia reperfusion model

OBJECTIVE: To investigate the effect of brain functional recovery decoction(BFRD) on expression of vascular endothelial growth factor(VEGF) and angiopoietin-1(Ang-1) protein in rats with cerebral ischemia reperfusion injury, and to explore the mechanism of action of BFRD.METHODS: Using the suture-occlusion method, a Wistar rat model of focal cerebral ischemia reperfusion was established. The rats were randomly divided into treatment group, model group, and sham operation group. The treatment group was administered BFRD. In situ hybridization was used to detect VEGF m RNA expression. Immunohistochemistry was used to observe expression of Ang-1 protein.RESULTS: VEGF mRNA expression was greater in the model group compared with the sham operation group(P < 0.05); Ang-1 protein expression was more obvious in the treatment group than the model group(P < 0.05).CONCLUSION: BFRD promoted VEGF m RNA and Ang-1 protein expression in the brains of rats with cerebral ischemia, suggesting increased angiogenesis.
