[Effects of escharectomy during shock stage on tissue high mobility group box-1 expression and balance of pro-/anti-inflammatory response in rats after severe thermal injury].
To investigate the effects of escharectomy during shock stage on tissue high mobility group box-1 protein (HMGB1) expression and balance of pro-/anti-inflammatory cytokines, and to elucidate the potential mechanism underlying beneficial effect of early escharectomy after severe burns. ⋯ Escharectomy during burn shock stage could inhibit the over-expression of both early and late inflammatory mediators, and maintain the balance of pro-/anti-inflammatory response, thereby improving multiple organ functions in rats following severe burns.

To review retrospectively the experience of surgical repair of sinus of valsalva aneurysm (SVA) in 70 patients. ⋯ The ruptured sinus of valsalva aneurysm and unruptured sinus of valsalva aneurysm with ventricle septal defect or(and) aortic valve regurgitation should be repaired surgically as soon as the diagnosis was confirmed. Long-term results are associated with preoperative aortic valve regurgitation.

To study the effective method of microsurgical resection of the recurrent craniopharyngiomas. ⋯ The desirable removal of recurrent craniopharyngioma could be completed in the majority of patients although the reoperation of the tumors was performed very difficulty owing to the tumor adhesive to the surrounding hypothalamic structures.

[Experimental research of myogenic motor evoked potentials to transcranial magnetic stimulation for spinal cord monitoring].
To evaluate the validity of intraoperative magnetic MEP (motor evoked potentials) monitoring in a spinal-cord-menaced surgery. ⋯ Myogenic TMS-MEPs was very sensitive to the spinal cord injury and should be a valid technique for intraoperative monitoring, and a slight change of them, even if a transient lose, should be unnecessarily related to a severe movement disorder. The warning threshold for a given patient should depend on the malady itself.

[Reoperation after surgical treatment of lumbar spondylolisthesis].
To study the causes of failure following surgical treatment of lumbar spondylolisthesis, procedures for redo surgery and the final result of reoperation. ⋯ Simple laminectomy or discectomy was not indication for lumbar spondylolithesis. No bone graft or union was the main causes of implant failure. Posterior instrumented fusion with laminectomy decompression can be used in the patients who had a prior surgery of simple discectomy or anterior intervertebral bone graft. Except for posterior instrumented fusion with extensive laminectomy decompression, Intervertebral fusion should be considered in the patients who had a prior surgery of laminectomy decompression with instrument, anterior intervertebral fusion (ALIF) was recommended for these cases.
