RESUMO
@#Objective To observe the effect of neuromuscular electrical stimulation and swallowing trainging on dysphagia after stroke.Methods 60 stroke patients following dysphagia were randomly divided into neuromuscular electrical stimulation group (n=20), swallowingtraining group (n=20), and combined therapy group (n=20), which received neuromuscular electrical stimulation, swallowing training, orcombined treatment of the above respectively, on the basis of routine treatment. Swallowing function was assessed by Kubota test and videofluoroscopyswallowing study (VFSS). Results The scores improved significantly in three groups after the treatment (P<0.05), and combinedtherapy group improved best (P<0.01). Conclusion Neuromuscular electrical stimulation and swallowing training can improve swallowingfunction after stroke, and combined therapy was more effective.
RESUMO
OBJECTIVE@#To investigate the expressions of matrix metalloproteinase-9 (MMP-9) and interleukin-8 (IL-8) in nasopharyngeal carcinoma and their association with Epstein-Barr virus latent membrane protein-1 (LMP-1).@*METHOD@#The expressions of MMP-9, IL-8 and LMP-1 were immunohistochemical studied in 53 nasopharyngeal carcinoma sections. We statistically analyzed the correlation of these data and also the relationship between the clinical features and the experimental data of these patients.@*RESULT@#The positive expression rate of MMP-9, IL-8 and LMP-1 were all 66.04% (35/53) and their average expression score were (33.19 +/- 29.73)%, (33.46 +/- 30.23)%, (35.49 +/- 29.63)% respectively. The expressions of MMP-9 and IL-8 both showed positive correlation with the expression of LMP-1 (r = 0.792, 0.786 respectively). The expressions of MMP-9, IL-8 and LMP-1 showed significant relationship with lymph nodes metastasis (P < 0.05), but no-significant association with age, gender, pathological classification, and clinical stage.@*CONCLUSION@#The expressions of MMP-9, IL-8 and LMP-1 were significantly associated with neck lymph nodes metastasis in nasopharyngeal carcinoma. The correlation between LMP-1 and MMP-9, IL-8 showed LMP-1 might enhance neck lymph nodes metastasis by up-regulating the expressions of MMP-9 and IL-8.
