摘　　要：【目的】局部免疫球蛋白高表达是慢性鼻窦炎伴鼻息肉(CRSwNP)重要病理特征,本研究主要探讨亚洲CRSwNP中边缘区B和B-1(MZB1)与局部免疫球蛋白表达的关系。【方法】通过聚合酶链式反应(PCR)、lu-minex、免疫组化染色对40例CRSwNP患者的鼻息肉组织和6名健康对照者的下鼻甲分别进行mRNA水平和蛋白质水平的检测,通过单因素方差分析、独立样本t检验和Pearson相关性分析进行统计检验。【结果】与健康对照组相比,2型CRSwNP中MZB1(P<0.01)和HSP90B1(P<0.01)的mRNA表达水平显著升高,免疫组织化学染色显示MZB1蛋白表达在2型CRSwNP中表达显著增加。此外,MZB1与鼻息肉组织中的免疫球蛋白E(IgE)的表达呈线性相关(P<0.01,r=0.52)。MZB1与2型CRSwNP鼻息肉组织中的白细胞介素-5(IL-5)(P<0.05,r=0.4)、白细胞介素-13,(IL-13)(P<0.05,r=0.44)的表达也呈线性相关。MZB1与鼻息肉组织嗜酸性粒细胞数线性相关有统计学意义(P<0.05,r=0.72)。【结论】与对照组相比,MZB1在亚洲CRSwNP中表达显著增加,尤其是2型CRSwNP,并且与鼻息肉组织中IgE的高表达和CRSwNP疾病严重程度相关。【Objective】The heightened expression of local immunoglobulins is a significant pathological characteristic of chronic rhinosinusitis with nasal polyps(CRSwNP),particularly in the Asian population.This study is centered on ex-ploring the association between MZB1 and the localized aggregation of immunoglobulins in Asian individuals with CRSwNP.【Methods】Nasal polyp tissues obtained from 40 CRSwNP patients and inferior turbinates from 6 healthy controls under-went examination for both mRNA and protein levels.The assessments were conducted using polymerase chain reaction,lu-minex,and immunohistochemical staining.Statistical analyses,including one-way Anova(ANOVA),independent sam-ples t-test,and Pearson′s correlation analysis,were employed for comprehensive data evaluation.【Results】The mRNA ex-pression levels of MZB1(P<0.01)and HSP90B1(P<0.01)were significantly higher in type 2 CRSwNP patients com-pared with those in healthy controls.Immunohistochemical staining revealed a significant increase in MZB1 protein expres-sion in type 2 CRSwNP.MZB1 demonstrated correlation with the expression of immunoglobulin E in nasal polyp tissues(P<0.01,r=0.52).Additionally,MZB1correlated with the expression ofIL-5(P<0.05,r=0.4)and IL-13(P<0.05,r=0.44)in nasal polyp tissues.Furthermore,MZB1showed correlation with the number of eosinophils in nasal polyp tis-sues(P<0.05,r=0.72).【Conclusion】The expression of MZB1 is notably elevated in Asian CRSwNP,particularly in type 2 CRSwNP,when compared with controls.MZB1expression correlates significantly with high IgE expression and dis-ease severity in nasal polyp tissues.
