RESUMEN
Objective To investigate the treatment effects of operation and nerve growth factor on adult multisegmental cervical spinal cord injury without fracture dislocation.Methods Sixty-eight patients with multiple segmental cervical spinal cord injury without fracture dislocation,admitted to our hospital from January 2004 to May 2011,were chosen in our study; according to the will of the patients,18 patients received conservative treatment (group A),25 patients were treated by posterior single open-door laminoplasty (group B) and the other 25 patients were treated with posterior single open-door laminoplasty combined with nerve growth factor (group C,once daily for 4 weeks); their clinical data were retrospectively analyzed.Follow up was performed at 3,6 and 12 months after the treatments;Japanese Orthopaedic Association (JOA) scale was employed to evaluate the clinical efficacy.Results Three,6,12 months after the treatments,the JOA scale scores were statistically different among the three groups (P＜0.05); the scores in group B and C were significantly higher than those in group A at all time points (P＜0.05); 6 and 12 months after the treatmemts,the JOA scale scores in group C were significantly higher than those in group B (P＜0.05).Conclusion To patients with multisegmental cervical spinal cord injury without fracture dislocation,conservative treatment can make the spinal cord function partially restored,but the effect is limited; exogenous nerve growth factor has good repairing effect on spinal cord injury.
RESUMEN
<p><b>OBJECTIVE</b>To investigate the influence of continuous high-volume hemofiltration (CHVHF) on interleukin 1 receptor-associated kinase-4 (IRAK-4) and tumor necrosis factor-alpha (TNF-alpha) levels in patients with severe acute pancreatitis (SAP).</p><p><b>METHODS</b>Forty-one patients with SAP were randomly divided into two groups to receive treatment with CHVHF plus conventional therapy (21 patients) and conventional therapy only (20 patients). Venous blood samples were taken before and 12, 24, and 72 h after the treatment for evaluation of APACHE II scores. The mRNA and protein levels of IRAK-4 in the monocytes were determined by real-time PCR and Western blotting, respectively, and serum TNF-alpha levels was detected using enzyme-linked immunosorbent assay (ELISA).</p><p><b>RESULTS</b>Among the 21 patients receiving CHVHF, 18 survived and 3 died, and in the conventional therapy group, death occurred in 5 cases. In the surviving patients of CHVHF group, the APACHE II scores, IRAK-4 mRNA and protein levels and TNF-alpha levels were all significantly lowered after the treatment, and these indices were also significantly lower than those in the conventional group after treatment (P<0.05).</p><p><b>CONCLUSION</b>CHVHF is effective in reducing monocyte IRAK-4 levels and serum TNF-alpha level in SPA patients, and thus alleviates the symptoms and improves the prognosis of SAP, possibly by reducing the level of the activators that induce monocyte activation via the Toll-like receptor.</p>
