The SMMC-7721 hepatoma cell line of experimental groups and control groups were cultured with the addition of sodium selenite, potassium iodide or triiodothyronine (T3). The cell quantity was checked by the MTT assay , and the cell cycle was observed by flow cytometry and levels of AFP and ALB in the culture solution were determined by RIA.The SD rats were divided into positive control group, negative control group, T3 group and mixture group (the mixture of sodium selenite, KI and T3). After two weeks of the administration of sodium selenite、 KI and T3,Walker256 cells were transplanted into the abdominal cavity. The administration was kept on for another two weeks, then observed the morbility and mortality of the rats with ascites carcinoma. At the end, the ascites were for the cells counting and the cell cycles analysising.

方 法：在体外，应用细胞培养的方法，培养SMMC－7721肝癌细胞系，分为试验组和对照组，试验组加入不同浓度Se、I或T3干预，培养一段时间后，通过噻唑蓝试验、流式细胞仪，观察细胞数量及细胞周期的变化，测定细胞培养上清液中甲胎蛋白、白蛋白的水平，观察细胞分化情况；在体内，将试验用SD大鼠分成阴性对照组、阳性对照组、T3组和混合组（为Se、I和T3混合物），首先预防性用药2周，然后给试验组大鼠和阳性对照组大鼠腹腔注射Walker256细胞，制造腹水癌大鼠模型；继续用药2周，观察各组大鼠发病率及死亡率，测量不同时期大鼠血清FT3含量，通过流式细胞仪测量大鼠腹水细胞数及细胞周期变化。
