RESUMEN
Objective To review the clinical characteristics,diagnosis and treatment of flail leg syndrome and to promote awareness among clinicians of this disease.Methods We presented the clinical data,neural electrophysiological examination results,and cervical/lumbar MRI and follow-up results of an inpatient vith flail leg syndrome at China-Japan Union Hospital and then reviewed relevant cases reported in literature.Results The patient with flail leg syndrome had a slow and asymmetric onset of atrophy of the distal muscles and weakness in the lower limbs,gradually progressing to the proximal lower limbs while the brain stem was moderately involved.Electrophysiology displayed not only motor nerve conduction amplitudes falling more than 48％ or even disappearing in both lower limbs,but also extensive neurogenic damage in the brain stem,cervical,thoracic and lumbosacral areas.Laboratory tests showed abnormally high creatinc kinase levels.Conclusions Flail leg syndrome has been inadequately studied so far and can be easily misdiagnosed.Reviewing its characteristics should be helpful for clinicians to make the right diagnosis and prognosis.
RESUMEN
Objective:To explore the effect of astragalus polysaccharides on the cellular immune functions in rats with sciatic nerve Wallerian degeneration.Methods:10 female Wister rats were established as the sciatic nerve injury model,which were randomly divided into astragalus polysaccharides group and control group.Then 20 mg/kg of astragalus polysaccharides were peritoneal injected every postoperative day in experimental group for 7 days and the same volume of saline for the control group.The content of IL-1? in serum and in supernatants of spleenocytes and macrophages was measured by Sandwich ELISA.Results:The proliferation ability of splenic T cells and macrophages in astragalus polysaccharides group was higher than that of control group(P0.05).Conclusion:Astragalus polysaccharides induces the cellular immuno-regulation in sciatic nerve Wallerian degeneration rats and by this way to promote nerve regeneration.
