Abstract Objective To observe the difference of the degree of expression of p38 mitogen-activated protein kinase (p38 MAPK)in chronic rhinosinusitis(CRS)without nasal polyps(CRSsNP),CRS with nasal polyps (CRSwNP)and normal uncinate process,and the expression of interleukin-6 (IL-6),hypoxia-inducible factor 1 alpha (HIF-1α)and vascular endothelial growth factors(VEGF)in different types of CRS.And explore the possible mechanism of p38MAPK signaling pathway in CRS.Methods Patients with nasal endoscopic surgery in department of otolaryngology of Qingdao Municipal Hospital were selected from July 2015 to July 2016 in Qingdao municipal hospital otolaryngology.32 cases of patients with CRSsNP sinus tissue,30 cases of CRSwNP patients with nasal polyps and 24 cases of with normal uncinate mucosa were selected for the study.The protein expression of p38 MAPK in three groups was detected by Western blotting.And the mRNA expression levels of IL-6,HIF-1α and VEGF in three groups were detected by reverse transcriptase-polymerase chain reaction (RT-PCR). Results The expression of p38MAPK in CRSsNP and CRSwNP was higher than that in normal mucosa,but there was no sig nificant difference between the twogroups(P=0.143).The expression of IL-6 in CRSsNP and CRSwNP was higher than that in normal mucosa,but there was no significant difference between two groups (P=0.082).The expression of HIF-1α and VEGF in CRSwNP was significantly higher than that in normal tissues (P<0.05).While there was no significant difference in the expression of VEGF in CRSsNP and normal tissues(P=0.075).Conclusion p38 MAPK in CRSsNP and CRSwNP shows a different correlation with inflammatory factor IL-6,and the advantage of the expression of IL-6 in CRSsNP and CRSwNP is different,and the expression of IL-6 in CRSsNP is more significant and more closely related.HIF-1a and VEGF are also highly expressed in CRSwNP tissues,which may be related to the production of polyps.
