The expression and role of MIF, NF-κB and IL-1β in nasal polyps / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To investigate the expression of MIF, NF-κB p65 and IL-1β in the tissue of nasal polyps and normal inferior turbinate, to analyze their relevance, and to explore their role in nasal polyps.@*METHOD@#The infiltrating results of EOS and others inflammatory cells in 48 cases diagnosed as nasal polyps (nasal polyps group) were detected by HE staining, and the expression of MIF, NF-κB p65 and IL-1β were investigated by immunohistochemistry. Twenty-one patients who were performed septoplasty orthotics were included as the control group; the VAS and Lund-Kennedy score were used to evaluate the degree of nasal polyps in patients and the correlation analysis was conducted between the disease severity and the expression levels of this three factors.@*RESULT@#(1) The infiltrating results of EOS and the expression level of MIF, NF-κB p65, IL-1β in nasal polyps group are obviously higher than these in the control group (P 0.05).@*CONCLUSION@#MIF, NF-κB p65 and IL-1β may promote the development of the nasal polyps, and there may exist the IL-1β--NF-κB--MIF approach in nasal polyps; MIF and NF-κB may participate in maintaining physiological function of inferior turbinate and have relations with the lightest sustained inflammation of inferior turbinate. The MIF and NF-κB p65 nuclear activation rate can be used as a standard of the nasal polyp severity and the judgement prognosis.

Research progress in role of myosin light chain kinase in pathogenesis of nonalcoholic fatty liver disease / 临床肝胆病杂志

Myosin light chain kinase (MLCK) is a key enzyme involved in intestinal mucosal mechanical barrier and plays an important role in the pathogenesis of nonalcoholic fatty liver disease (NAFLD). This article describes the "two-hit theory" for NAFLD and gut-derived endotoxin which plays a major role in the pathogenesis of NAFLD, the relationship between endotoxin, MLCK, and NAFLD, and the impact of MLCK inhibitor ML-7 on the intestinal barrier. MLCK inhibitor ML-7 may hinder and delay the development and progression of NAFLD, providing a novel clinical idea for the early prevention of NAFLD.
