Methods: Prepare seaweed Yuhu Decoction medicated serum, select human normal thyroid cells Nthy-ori3-1 as the normal control group, and PLX4032 as the positive control drug. The experiment was divided into normal control group, model control group, PLX4032 group, Haizao Yuhu Decoction group (referred to as HYD group), Haizao Yuhu Decoction group + PLX4032 (referred to as HYD+PLX4032 group), and high iodine water group, at 8h and 24h respectively. At 72h, the cell proliferation of each group was detected by MTT method;at 24h, the expression of ERK and p-ERK protein in each group was detected by Western blot. Results: The longer the time, the more obvious the inhibitory effect of Haizao Yuhu Decoction-containing serum on the proliferation activity of BCPAP cells: Compared with the normal control group, the BCPAP cell proliferation activity of the model control group was significantly enhanced at 24h and 72h (P <0.05);At 24h, the PLX4032 group, HYD group, and HYD+PLX4032 group all showed a tendency to inhibit the proliferation of BCPAP cells, but there was no statistical difference;at 72h, compared with the model control group, the PLX4032 group The cell proliferation activity of the HYD group and HYD+PLX4032 group was significantly inhibited (P <0.05), and there was no difference between the high iodine water group and the model control group (P>0.05). In inhibiting the proliferation of BCPAP cells, the medicated serum of Shanghai Zaoyuhu Decoction has a synergistic effect with PLX4032 (F=10.87, P=0.005). Western blot results showed that there was no difference in the expression of ERK1/2 protein between the groups, but there were significant differences in the expression of p-ERK1/2 protein between the groups: Compared with the normal control group, the expression of p-ERK1/2 protein in the model group increased significantly (P < 0.05);Compared with the model control group, the e展开更多
