Résumé

OBJECTIVE To investigate the expression of zonula occluden-1(ZO-1) in hypopharyngeal squamous cell carcinoma(HSCC) and its clinical significance.METHODS Immunohistochemistry with tissue microarrays was used to detect the expression of the ZO-1 protein in 52 cases of HSCC.The correlation of prognosis and clinicopathological features was analyzed.RESULTS The expression of ZO-1 protein in HSCC was lower than that in adjacent tissues,its expression was closely related with tumor differentiation,tumor stage,tumor location and lymphatic metastasis.The Log-rank univariate analysis showed that the prognosis of HSCC was related to tumor differentiation,tumor stage,lymphatic metastasis and tumor location.The patients with lower expression of ZO-1 showed the worse prognosis than patients with higher expression of ZO-1.As shown in the Cox regression analyses,tumor differentiation,lymphatic metastasis,the ZO-1 expression and tumor stage were all independent prognostic factors.CONCLUSION The ZO-1 can serve as an independent prognostic factor of HSCC,and the low expression of ZO-1 is closely related to poor prognosis.

Résumé

OBJECTIVE@#To study the relationship between fibrinogen level and pathogenesis of sudden sensorineural hearing loss(SSHI.).@*METHOD@#Fifty patients (55 ears) with SSHL within 7 days of the onset were studied: a control group was consist of 50 normal-hearing people who were individually matched on a pairwise basis according to the same gender and age. Both the patients and the normal people were tested for the parameters of hemorheology, blood biochemistry, whole blood cell count and clotting function.@*RESULT@#Fibrinogen level and plasma viscosity in patients with SSHL were significantly higher than that in control subjects. Prothrombin time and activated partial thromboplastic time were significantly less in the patients group than that in the control group (P 0.05).@*CONCLUSION@#Elevated plasma fibrinogen may be a major pathogenesis of SSHL. An increase in plasma fibrinogen level may lead to elevated plasma viscosity. All these may promote a prothrombin or hypercoagulable state and impair blood perfusion of cochlea.
