摘要
This work studies the expression differences of YKL-40 and TLR4 in nasal sinus mucosa of chronic sinusitis patients with and without nasal polyps and its clinical significances. Fifty chronic sinusitis patients with nasal polyps and 50 chronic sinusitis patients without, accepted by our hospital during February 2016-February 2017, were included and taken as group A and group B, respectively. In addition, another 50 patients with nasal deviation were taken as group C (control group). The ostiomeatal complex mucosa of group A and B and the inferior turbinate mucosa of group C were taken and the fluorescence quantitative PCR method was applied to detect the expression of YKL-40, TLR4 and NF-kappa B of the mucosa and explore and influence of YKL-40 and TLR4 on NF-kappa B. There was a negative correlation between YKL-40 and TLR4 in group A, and the difference was statistically significant (P <0.05) while there was no relationship between YKL-40 and TLR4 expression in group B. The level of YKL-40 protein in group A was higher than that in group B, which was statistically significant (P <0.05). YKL-40 and TLR4 were positively correlated in group A while there was no correlation between YKL-40 and TLR4 expression in group B. The expression of YKL-40, TLR4 and NF-kappa B in chronic sinusitis patients with nasal polyps was high. In addition, there was a negative correlation between YKL-40 and TLR4 expression in chronic sinusitis patients with nasal polyps. YKL-40 and TLR4 interacted with each other to activate NF-kappa B and promote disease progression.
