ABSTRACT
Objective To evaluate the clinical efficacy of ventricle -peritoneal or ventricle-atrial shunt in the treatment of skull defect with craniocerebral trauma combined with hydrocephalus in the same period. Methods Sixty-four patients with skull defect after craniocerebral trauma combined with hydrocephalus were randomly divided into observation group (n=32) and control group (n=32) The ventricle-peritoneal or ventricle-atrial shunt and skull repair were conducted simultaneously following surgical operation in observation group whereas ventricle-peritoneal or ventricle-atrial shunt and the skull defect were performed within 3 months and after 3 months following operation, respectively. The hydrocephalus symptoms, prognosis after three months ,clinical outcomes and the postoperative complications were evaluated. Results There was no significant difference in hydrocephalus symptoms between the observation group and control group (χ2=0.005,P>0.05). The GCS score, GOS score and neurological function score after three months were better than those before the treatment in these two groups (P<0.05). These functional parameters were significantly better in the observation group than in control group (P<0.05). The good rate in three months was significantly higher in the observation group than in control group (59.38％vs 31.25％,χ2=7.23, P<0.05). The incidence of complication was 6.25％(2/32) in the observation group, which was significantly lower than that in the control group (31.25％, 10/32) (χ2=7.13, P<0.05).Conclusion Cranioplasty combined with shunt in the treatment of skull defect complicated with craniocerebral trauma-associated hydrocephalus has low postoperative complications, good clinical prognosis and reliable efficacy, which is worthy of clinical application.
ABSTRACT
BACKGROUND:Recent studies have found that bone marrow mesenchymal stem cels that culturedin vitro for a long time can naturaly differentiate into neural stem cels, which then differentiate into neurons and glial cels, thereby providing a new therapeutic thinking for Parkinson’s disease, sequela of cerebral infarction, cerebelar atrophy and brain dysplasia. OBJECTIVE:To discuss the influence of neural stem cel transplantation on neurologic function of rats with cerebral hemorrhage at recovery stage and the relevant mechanism of action. METHODS: Sixty male Sprague-Dawley rats were randomly divided into normal group (n=18), cerebral hemorrhage group (n=21) and transplantation group (n=21). Cerebral hemorrhage models were established in the latter two groups using VII type colagen enzyme induction method. At 21 days of modeling, rats in the transplantation group were injected neural stem cels via the tail vein, and those in the other two groups received the same volume of normal saline. At 7, 14, 21 days after cel transplantation, modified adhesive removal test (MST) was employed to evaluate the neurologic function of rats, and then the rats were kiled. RT-PCR was used to detect angiopoietin-1 mRNA expression in the bleeding tissues, and western blot assay was employed to measure tyrosine kinase receptor-2 protein expression. RESULTS AND CONCLUSION:Compared with the normal group, the MST scores in the cerebral hemorrhage group and transplantation group were significantly decreased (P cerebral hemorrhage group > normal group, and there was a significant difference among the three groups (P< 0.05). These findings indicate that neural stem cel transplantation can effectively promote the neurologic recovery of rats with cerebral hemorrhage at recovery stage, and the concrete mechanism may be related to the increase of angiopoietin-1 mRNA and tyrosine kinase receptor-2 protein in the bleeding tissues.
ABSTRACT
Objective To investigate the therapeutic effect of autologous stem cell transplantation research for patients with cerebral hemorrhage sequelae under the stereotactic.Methods One hundred patients with cerebral hemorrhage from Jan.2011 to Sep.2013 in our hospital were selected and randomly divided into the experimental group (n =50) and the control group (n =50).The patients of experimental group were given autologous stem cell transplantation under the stereotactic in 6 months after cerebral hemorrhage,while the patients in control group were just given traditional treatment.At 6,7 and 12 months after cerebral hemorrhage,rate with neural function defect scale and functional independence measure(FIM) scores of the two groups were compared.Results FIM scores in the experimental group was 102.08 ± 8.28,significant higher than that in control group(95.28±8.75,P＜0.05).Functional independence measure scores in the experimental group at 7 months after cerebral hemorrhage was 13.12±4.00,significant lower than that in control group(20.40±4.33,P ＜0.05).While,there was no statistical difference at 6 months and 12 months after cerebral hemorrhage between the two groups(P＞0.05).Conclusion The therapeutic of autologous stem cell transplantation on patients with cerebral hemorrhage sequelae under the stereotactic is benefit at short term,but the long term therapy effective still needs further study.
