Conclusion SFK could effectively reverse the abnormal hemorheological status into normal one.

In recent decades, the development of the neurosurgery has changed from the traditional anatomical model to the modern anatomical-functional model. The nerve functions are maximally protected while lesions are removed as far as possible. Neurophysiological monitoring especially somatosensory evoked potentials (SEPs) and motor evoked potentials (MEPs) can directly reflect the integrity of the sensory and motor nerve conduction pathways of the nervous system. At present, it has been widely used in the neurosurgery, spinal surgery, vascular surgery and other surgical fields. In recent years, more and more clinical surgeries involved spinal surgery, intraoperative neurophysiological monitoring could timely find any reversible spinal cord damage such as mechanical stretch, ischemia, and anesthetic drugs, which not only improve the quality of surgery, reduce iatrogenic spinal cord injury, but also greatly improve the prognosis of patients and reduce postoperative neurological dysfunction and complications. In this paper, the research progress of neural electrophysiological monitoring techniques in spinal cord surgery is reviewed.

Objective:This study aimed to develop a Chinese version of Quality of life in Epilepsy Inventory(QOLIE-89) and to confirm its psychometric properties.Methods:The original English version QOLIE-89 was adapted to Chinese language through a translation back-translation procedure. The assessment included 204 patients with epilepsy .The test-retest and internal consistency reliabilities, criterion validity and discriminative validity were assessed.Results:The test-retest reliability (Pearson's correlation coefficient) for Chinese version QOLIE-89 was 0.63-0.95 and internal consistency reliability (Cronbach's alpha) was 0.76-0.92. The confirmatory factor analysis indicated that the Chinese version of QOLIE-89 was composed of three dimensions(CMIN/DF=2.17,GFI=0.98, AGFI=0.90, CFI=0.98,RMSEA=0.061), which were physiology, psychology and social function that including 17 factors obtained by exploration analysis ,which can explained 71.91% of total variance. Spearman's rank correlations between Chinese version QOLIE-89 total score and QOLIE-31 total score was 0.96 and domain scores were from 0.86-1.00.QOLIE-89 items could be discriminated well between patients according to epileptic seizures severity and antiepileptic drug side effects.Conclusion:The psychometric properties of the Chinese version QOLIE-89 inventory are fairly good and similar to the American version and can be applied to assess quality of life for adult patients with epilepsy in China.

Objecfive To investigate the effects of endotoxin on nuclear factor-κB p65(NF-κB p65)mRNA expression and ahtosteron secretion in rat hepatic stellate cells(HSCs).Methods Cultured rat HSCs(HSC-T6)were divided into endotoxin-treated group and control group.Cells in endotoxin-treated group were exposure to 1 mg/ml.endotoxin.Aldosteron secretions of HSCs were determined by radioimmunoassay,and NF-κB p65 mRNA expressions of HSCs were detected by one-step RT-PCR.Results At 6,12,24 and 48 h,aldosteron secretions in endotoxin-treated group were significantly hisher than those in the control group(t=3.063,4.577,6.847 and 9.317,P<0.05),and the expressions of NF-κB p65 mRNA in endotoxin-treated group were also higher than those in control group(t=5.155,6.095,7.875 and 9.313,P<0.01).Aldosteron secretions and NF-κB p65 mRNA expressions in HSCs displayed a positive correlation(r=0.886,P<0.01).Conclusion Endotoxin can up-regulate the aldosteron secretion and NF-κB p65 mRNA expression in rat HSCs,which may be one of the mechanisms of liver fibrosis induced by endotoxin.

Objective To evaluate the clinical value of prone flexed posture lumber CT/MRI examination for lumber disc herniation. Methods Supine posture CT/MRI (SPCT/MRI) and prone flexed posture CT/MRI (PFPCT/MRI) examinations were performed on 1200 patients with lumber disc herniation.The imaging findings on SPCT/MRI and PFPCT/MRI of each case were compared. According to the CT/MRI diagnostic criteria for encapsulated lumber disc herniation ( HLDH ), adhered lumber disc herniation (ALDH) and ruptured lumber disc herniation ( RLDH), the 1200 cases were divided into three groups. On the basis of PFPCT/MRI findings, 868 cases were selected for percutaneous lumbar diskectomy (PLD) with half to twelve years follow up. Treatment effects of PLD on HLDH, ALDH and RLDH were analyzed with x2test. Results Among 249 ALDH cases diagnosed by SPCT/MRI 35 were identified as HLDH by PFPCT/MRI. Among 163 RLDH cases diagnosed by SPCT/MRI, 9 HLDH and 17 ALDH were identified by PFPCT/MRI. In 868 cases treated with PLD, the effective rate of HLDH ( n = 832), ALDH ( n = 25 ), RLDH ( n =11 ) were 825/832 (99. 2% ), 13/25, and 1/11 respectively. The effective rate of HLDH is significantly different from that of ALDH and RLDH ( x2 = 369. 69, P ＜ 0. 01 ). Conclusion PFPCT/MRI may change the grouping result of lumber disc herniation made by SPCT/MRI and can be used to objectively select patients for PLD.

BACKGROUND: Previous studies demonstrated that recombinant human bone morphogenetic pretein-7 (hBMP-7) can effectively promote the synthesis of extracellular matrix, repair of damaged disc matrix, restore of degenerative disc height. It is hoped that BMP-7 can be used to control and reverse the intervertebral disc degeneration. However, because of the short half-life of recombinant protein and low biological activity, it is difficult to maintain BMP-7 high concentrations on degenerative disc. Gene therapy can prevent these defects effectively.OBJECTIVE: To study the effect of hBMP-7 gene transfeotion on biological activity of primary cultured rabbit nucleus pulposus cells in vitro, to determine the feasibility of hBMP-7 gene which will on gene therapy research of intervertebral disc degeneration,and to provide basis for further study.DESIGN, TIME AND SETTING: A randomized and controlled observation was performed at the Institute of Cardiothoracic Surgery of Changhai Hospital from December 2005 to September 2006.MATERIALS: Six healthy New Zealand white rabbits of either gender, averaging 4 weeks old and weighing 500 g, were used in this study, and Ad-hBMP7 was constructed by the Cardiothoracic Surgery Institute of Changhai Hospital.METHODS: After rabbits sacrifice under aseptic condition, the nucleus pulposus was got. After digested with Pronase, type Ⅱcollagenase and type Ⅱ DNAase (4 hours, 37 "(2), the cells were seeded in the Petri dishes and were kept in the incubator. After 7 days and then twice a week, the media were refreshed. The nucleus pulposus cells were infected by adenovirus integrated with hBMP7 gene. The cells which were transfected by adenovirus vector for Lac-Z gene and which were not transfected were adopted as control.MAIN OUTCOME MEASURES: The expression of hBMP-7 was determined by RTopCR and Western blot. The effect of hBMP-7 on cell proliferation was surveyed by MTT. Furthermore, the effect of hBMP-7 gene on synthesis of proteoglycan and type Ⅱcollagen was detected by modified dimethylmethylene blue method and ELISA, respectively.RESULTS: Gene sequencing and PCR showed that hBMP-7 gene was inserted correctly and no mutation happened. The pdmary cultured rabbit nucleus pulposus cells were identical with those reported in literature. After Ad-hBMP7 transduct into the nucleus pulposus cells, high level of hBMP-7 expression was observed and lasted over 3 weeks. Also hBMP-7 gene can promote cell proliferation and synthesis of proteoglycan and type II collagen with significant difference compared with control groups (P < 0.05).CONCLUSION: hBMP-7 gene mediated by adenovirus can be the target gene for the further study on gene therapy of intervertebral disc degeneration.
