RESUMO
Objective To investigate the effect of neruomodulation treatment,including deep brain stimulation (DBS) and spinal cord stimulation (SCS),on patients under persistent vegetative state (PVS).Methods Fifty-three patients diagnosed as having PVS,admitted to our hospital from July 2011 to December 2012,were chosen in our study; after selection,42 patients were enrolled (27 males and 15 females,mean 42.9±5.47 years old) and prospectively divided into control group (n=20) and surgical group (n=22).Patients from surgical group received DBS (n=5) and SCS (n=17) treatments,while patients from control group underwent routine rehabilitation activities.Behavioral assessments were repeatedly performed using Revised Coma-Recovery Scale (CRS-R).Some patients underwent functional magnetic resonance imaging (fMRI) to further assess the outcomes.Clinical baseline values were collected and compared to follow-up data.Results No statistical significant differences of age,duration of coma and CRS-R scores were noted between the two groups before treatment.Thirty-seven patients (17 in control group and 20 in surgical group) got follow-up for 6-24 months (median 11.2 months); seven patients in the surgical group emerged from PVS to achieve consistent discemible behavioral evidence of consciousness with a recovery rate of 35 ％ (7/20),while only 1 from the control group with a recovery rate of 5.9％(1/17); significant difference was noted between the two groups (P＜0.05).Improvement in behavioral assessments (CRS-R scores) in the surgical group was significantly better than that in the control group (P＜0.05); however,no significant difference of CRS-R scores was noted between patients received DBS and SCS treatment (P＞0.05).The fMRI showed good consistency of activation of resting state default network key area and function connected degree with clinical assessment.Conclusion Neuromodulation therapy can effectively promote awareness of PVS patients based on rigorous selection criteria; DBS and SCS treatments show no difference in the clinical efficacy.
RESUMO
[Objective]To apply the isobaric tagging for relative and absolute quantitation (iTRAQ) and liquid chromatography-tandem mass spectromeury (LC-MS/MS) to identify the proteins differentially regulated in CSF of patients before and after stem cell transplantation.[Methods]CSF samples fiom patients with central nervous system injury before and after stem cell transplantation and from normal controls were collected;selective removal of high-abundant proteins was performed by high performance liquid chromatography;proteins were differentially identified by iTRAQ-coupled LC-MS/MS.[Results] Totally,59 proteins were identified.As compared with control group,the patients before transplantation had 5 over-expressed proteins and 8 under-expressed proteins;only 7 proteins in patients after transplantation showed no significantly different expression as compared with those in control group.[Conclusion] Protein expression is significantly changed in CSF of patients with central nervous system injury after neural stem cell transplantation,suggesting that the proteomics research can help us to find markers of nervous system damage and is important to mechanism study on nervous system damage and repair.
RESUMO
Objective To explore the problems of microsurgical treatment of multiple intracranial aneurysms with regard to the indications,surgical timing,operative approaches and the prevention of complications, and improve their diagnoses and treatments. Methods We retrospectively reviewed the data of 33 patients with multiple intracranial aneurysms admitted to our hospital from Jan.2000 to Dec.2008 and their clinical manifestations,imaging features and microsurgical treatments were summarized. Results In the 33 cases of multiple intracranial aneurysms,the male-to-female sex ratio was 1:1.75 and the average age at onset of symptoms was 56.52.Twenty-four patients showed good postoperative prognosis(Glasgow Outcome Scale IV-V) with 2 deaths.Conclusion Individual treatment should be adopted in the treatment of differently localized multiple intracranial aneurysms with different sizes and clinical classifications,and the utilization of temporary blockade and ultrasound during the operation can improve the therapeutic effects and reduce the postoperative complication rates.
RESUMO
Objective To explore the methods, efficacy and advantages ofstereotactic surgery.Methods A retrospective analysis of 29 consecutive patients with 37 lesions (mean age, 34.6 years),received surgery between Dec 2002 and Nov 2009, was performed. Histological findings showed 11 craniopharyngiomas, 5 cystic gliomas, 3 metastases and 10 cerebral abscesses. Eighteen patients underwent cyst aspiration by the Ommaya reservoir system combined with 32P endocavitary irradiation;median irradiation doses were 800 μCi. One was treated with aspiration and then radiotherapy only. Ten patients with cerebral abscesses received cystic drainage (8 cases) and aspiration (2 cases). Results No operative bleeding and death were found in this experiment. Follow up was performed for a median of 10.6 months (range, 1-60 months) and 4 were out of contact. All patients with craniopharyngiomas remained stable without recurrence after treatment; complete resolution was achieved in all patients with cerebral abscess; in the other 8 patients with tumors(12 lesions), 5 were under control of the symptoms for an average of 14 months and 3 (2 with metastases and 1 with glioblastoma) did not get improvement after the treatment. Two patients with craniopharyngioma experienced a transient slightly worsening of hypothalamic functions, including transient diabetes insipidus, low fever and vomit. Conclusion Stereotactic technique has its advantages in treating patients with cerebral abscess, craniopharyngiomas,metastatic tumors and gliomas that were small size, while it does not that effective in the cystic metastases that are in large size and difficult to control in a short term.
