Correlation of HMGB1 expression with CD68+ macrophage infiltration in peritumoral and tumoral liver tissues in patients with HCC. Two-demissional plot showed HMGB1 overexpression correlated positively with CD68+ macrophage density in peritumoral liver tissue (a), while modest correlation was found between HMGB1 expression and CD68+ macrophage density in tumor tissues (b)
