结果 使用他莫昔芬1年以后，周期用药组、连续用药组、对照组平均内膜厚度分别为65±1.4、10.2±2.0和42±1.2。

The surface antigen expressions of MNC were detected by flow cytometry. MNC were induced with DMEM medium, containing HGF alone, FGF4 alone, HGF+FGF4 or no growth factor, respectively. The markers of hepatic linear cells were examined before induction, and 7, 14, 21 and 28 d after induction by RT-PCR, immunocytochemistry and periodic acid-schiff in every group.

分别用肝细胞生长因子、成纤维细胞生长因子-4(FGF4)、HGF+FGF4、无生长因子4种处理因素进行诱导培养，于诱导前及诱导后的第7、14、21、28天采用RT-PCR检测AFP、白蛋白及C-met、FGFR2 mRNA的表达，免疫细胞化学法检测肝细胞抗原和CK18的表达，PAS 法进行糖原染色。

The results showed that the content of Se element in the Se-MT was 2.5 folds higher than that of Zn-MT, on the contrary the content of sulfur element in Se-MT was 2 folds lower then Zn-MT, C, H, N contents in MT were no significant differences in both groups. In terms of chemical property, the element of selenium is very similar to sulfur because they are in the same group in the periodic table. The above results illustrated that the Se could replace S from SH-sulfhydryl to SeH-selenihydryl in cysteine, which presents the existence of a novel Se-MT.

结果表明Se－MT中Se元素含量高于Zn－MTZ.5倍左右，而 S元素含量低于 ZnMT 2倍左右，C、H、N元素含量无明显差异，这说明了麦硒康诱导后Se仙T分子结构上的差异，由于Se元素与S元素同属氧族元素，在化学性质上极为相似，故Se元素极可能替代了MT的合成过程中所必需半味氨酸残基中的SH一基因上的S元素成为SeH一基团，这样我们就得到了一种含SeH一基团的新型Se－MT。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.
