Clinical characteristics and surgical treatment of ganglioneuroma in spine / 中国骨伤

<p><b>OBJECTIVE</b>To summarize the clinical manifestation and diagnosis of ganglioneuroma in spine and investigate the clinical effect of surgical treatment.</p><p><b>METHODS</b>The clinical data of 6 patients underwent a surgery for ganglioneuroma in spine from January 2008 to January 2015 were retrospectively analyzed. There were 4 males and 2 females, aged from 2 to 63 years old with an average of 34.6 years. The courses of disease were from 3 days to 17 years. Five patients complicated with superficial hypesthesia in correlative level of tumor, and the muscle strength under tumor plane had decreased at different levels, with the strength of grade II-IV. Two cases complicated with hypermyotonia and positive bilateral Hoffmann's and Babinski sign. Five cases were sporadic lesion in correlative spinal canal and one case complicated with the giant occupying lesion in thoracic cavity.</p><p><b>RESULTS</b>Six operations had been performed including 5 en bloc and 1 subtotal resection. Postoperative pathological results showed tumor cells scattered or fasciculated inserted into Schwann cells in the stroma. In 2 patients complicated with radiculalgia before operation, 1 case was relieved and 1 was invariant after operation. All 4 patients with preoperative dyscinesia in the limbs obtained improvement after operation. All the patients were followed up from 0.3 to 6.8 years with an average of 2.5 years. At the final follow-up, according to ASIA grade, 5 cases were good and 1 case was invariant. During the follow-up, only 1 patient experienced chemoradiation because of merging ganglioneuroblastoma and receiving subtotal resection. No recurrence in other 5 cases.</p><p><b>CONCLUSION</b>Ganglioneuroma is a benign and rare tumors in spine. Clinically, radicular pain and sensory-motor disorders are the main manifestations. Its diagnosis depends on pathological examination. Prognosis of surgical treatment is good.</p>

Current situation and progression of induced pluripotent stem cells in treating spinal cord injury / 中国骨伤

Spinal cord injury is a difficult medical problem and current therapeutic methods could not obtain satisfactory results. Recent 20 years, stem cell technology developed rapidly, embryonic stem cells and adult stem cells were used for treating neurological disease and nerve injury of animal models and the clinical results were confirmed. It provided a new prospect for the treatment of nerve injury at the cellular level. However,due to technical and ethical problems, it is difficult to obtain the appropriate cells that can be applied to the human being. Recently, induced pluripotent stem cells were developed as a new method for the treatment of spinal cord injuries by the autologous transplantation. Starting from this work, the purpose of this review is to assess the differentiate ability of induced pluripotent stem cells into neurocyte and review the latest developments in this area.
