Objective To evaluate the pathophysiology of paraplegia during transarterial chemoembolization in liver cancer and investigate effective management and prevention for improving clinical situation and relieve major symptoms.Method 2758 patients accepted TACE procedure because of liver cancer(and/or combined with remote metastasis),demonstrated 4 cases suffering from paraplegia(3 males,1 female)since Mar.2003 to Feb.2005,with mean age of(51?14)years old,The operative records and the clinical features after chemoembolization were summarized in detail.Results The incidence of paraplegia was 0.145%,with major symptoms of dysesthesia and hypokinesise emerging within 4 hours after TACE,and most symptoms aggravating gradually within 24-48 hours untill paraplegia appeared,and then turned to stabilization about 5-7 days,with their body functions partial recovery in 2 months.Conclusion More attention should be paied to prevent ectopic embolization of spinal cord vessels originating from extrahepatic collateral arteries during TACE or TAE.

ObjectiveTo explore the clinical outcome of one stage posteroanterior decompression and bone implant in the treatment of severe lower cervical spinal bony canal stenosis. Methods The study involved 29 patients with severe lower cervical spinal bony canal stenosis treated with one stage posteroanterior decompression and bone implant from April 2006 to March 2009. There were 11 patients with old fractures, seven with posterior longitudinal ligament ossification and 11 with cervical disc calcification. The course of disease ranged from 2 months to 3.2 years, average 1.4 years. The nerve function was rated as grade B in two patients, grade C in 19 and grade D in eight according to Frankel scale. The average Japanese Orthopaedic Association (JOA) score was 9.8. ResultsAll patients were followed up for 7-28 months (average 15.2 months), which showed bony fusion five months after operation, with fusion rate of 100％. The Frankel grade was increased for average 1.2 grades and the nervous symptoms alleviated remarkably. Mean postoperative JOA score was 13.8 and increased for mean 4.0, with mean amehoration rate of 55.6％. ConclusionsOne stage posteroanterior decompression and bone implant is a safe and effective method for treatment of lower cervical spinal bony canal stenosis, when the intraoperative electrophysiological monitoring can assure the operative safety.

BACKGROUND:Studies have demonstrated that tetrandrine has protection on acute spinal cord injury,but the specific mechanism remains poorly understood.OBJECTIVE:To study the protection of tetrandrine on rat acute spinal cord injury and to study its mechanism from apoptosis pathway.METHODS:A total of 100 rats were randomly divided into 4 groups.All rats were prepared for spinal cord injury models using modified Allen method except that in the sham-surgery group.Methylprednisolone and tetrandrine was injected into rats in the methylprednisolone and tetrandrine groups by tail intravenous injection prior to and at 24,48 hours after model preparation.The same volume of physiological saline was injected in the sham-surgery and model groups.Basso-BeatUe-Bresnahan(BBB score)was recorded at 8 hours,1,3,7 and 14 days after model preparation.The morphological changes of spinal cord injury sites were observed by hematoxylin-eosin staining and the expressions of bcl-2 and bax were determined by immunohistochemistry.RESULTS AND CONCLUSION:The BBB score of methylpradnisolone and tetrandrine groups were significantly higher than that model group at 7 and 14 days(P<0.05),but there were no significant difference between the methylprednisolone group and tetrandrine group(P>0.05).Hematoxylin-eosin staining showed that the spinal cord injured severely at 3-7 days,the injury degree in the methylpradnisolone group and tetrandrine group was slighter than that of the model group,with smaller bax expression and greater bcl-2 expression(P<0.01).The findings demonstrated that,tetrandrine is able to protect neurons from apoptosis and promote the nerve function recovery by inhibiting the expression of Bax and promoting the expression of Bcl-2.Its effect is not inferior to methylprednisolone.

Objective To discuss the therapeutic options for treatment of subaxial cervical dislocation combined with facet locking. Methods There were 49 patients with cervical dislocations including 7 patients with dislocation at C3,4, 15 at C4,5, 14 at C5,6 and 13 at C6,7. Eleven patients were with old dislocation, with duration of dislocation ranging from 2 hours to 61 days. Neurologic status of the patients according to Frankel scale was graded A in 14 patients, grade B in nine, grade C in 10 and grade D in nine. All patients were treated surgically after closed reduction with skull traction. Results The successful reduction rate was 63% for fresh dislocation, with average improvement of 0.65 grade for spinal cord function. All bone grafts got fusion at four months after operation. Conclusion Therapeutic options are based on fresh or old dislocations, paraplegia or not, intervertebral disk injury severity, and reduction or not through traction for patients with lower cervical dislocations.
