The cell viability of HRECs in the treatment of hispidulin with normal glucose or with high glucose. A The cytotoxicity of hispidulin on the HRECs under normal glucose (NG, 5 mM) condition for 24 h. Data were shown as mean ± SD (n = 3) and analyzed by one-way ANOVA and followed by Dunnett’s multiple comparison test. ^*P < 0.05 and ^**** P < 0.001 versus NG group. B The cell viability of hispidulin on the HRECs under high glucose (HG, 30 mM) condition for 48 h and the NG group was regarded as control group. Data were shown as mean ± SD (n = 3) and analyzed by one-way ANOVA and followed by Dunnett’ s multiple comparison test. ^*P < 0.05, ^***P < 0.001 and ^****P < 0.001 versus HG group
