The effect of xiaoyuningkun decoction on the inflammatory response in the mouse model of pelvic inflammatory disease (PID). Enzyme-linked immunosorbent assay (ELISA) shows that xiaoyuningkun decoction reversed the increase in serum levels of interleukin-1β (IL-1β) (A), tumor necrosis factor-α (TNF-α) (B), intercellular adhesion molecule-1 (ICAM-1) (C), and vascular endothelial growth factor (VEGF) (D) in the upper genital tract of the mouse model of PID. Data are presented as the means±standard error (N=12). One-way analysis of variance (ANOVA) followed by Bonferroni’s post hoc test were performed. *** P<0.001 vs. the control group; # P<0.05, ## P<0.01, ### P<0.001 vs. the PID group.
