The cytokine protein expression levels in the intestinal mucosa in the PI-IBS (n = 20), non-PI-INS (n = 18) and control groups (n = 20). A. Representative graphs of the Western blot assay. Lane 1–3 PI-IBS; Lane 4–6 non-PI-IBS; Lane 7–9 healthy control group. B. Quantitative of expression of cytokines. Data are presented as mean ± SD. *P < 0.05 versus controls, #p < 0.05 versus non-PI-IBS group.
