Differential expression of IL10 in patients with CRS. Reverse transcription- polymerase chain reaction of IL10 and TNFa was performed and the expression levels of IL10 and TNFa were quantified relative to those of GAPDH. (A) IL10 in the nasal polyps was upregulated 2.0-fold of that in the CRSsNP group. (B) There was no significant difference in the expression levels of TNFa between the different groups. *P<0.05. ns, no significance; CRSwNP, chronic rhinosinusitis with nasal polyps; CRSsNP, chronic rhinosinusitis without nasal polyps; TNFa, tumor necrosis factor; IL, interleukin.
