Relative inhibitory by 5-FU, Sal and their combination for HCC cell lines.

Cells were exposed to a concentration range of 5-FU, Sal and their combination for 48 h.
Values (relative inhibitory) are means ± standard error of the mean (SE) for 3–5 experiments.

将细胞置于不同浓度梯度的5-氟尿嘧啶（5-Fluorouracil，5-FU）、Sal以及二者联合制剂中，孵育48小时。
相对抑制值为3~5次独立实验的均值±标准误（standard error of the mean，SE）。
