中文摘要：

目的：探讨咖啡酸锗对小鼠肝癌H22端粒酶活性及细胞凋亡的影响。方法：建立小鼠肝癌H22移植瘤模型，应用咖啡酸锗腹腔注射给药后，通过电镜观察H22细胞凋亡的情况以及用ELISA法半定量检测端粒酶活性。结果：咖啡酸锗能诱导H22细胞凋亡以及抑制端粒酶的活性，并与药物浓度有关。结论：咖啡酸锗能显著抑制H22细胞端粒酶的活性，抑制其细胞增殖，诱导其细胞凋亡。

英文摘要：

Objective：To investigate the effects of Caffeic acid Ge on telomerase activity and apoptosis on H22 cancer cells in mice. Methods ： Establishing model of H22 cancer cells in mice and after the treatment for abdominal using Caffeie acid Ge. Cell apoptosis was observed by transmission electron microscopy, and mice telomerase enzyme linked immunoassay（小鼠端粒酶 TE ELISA）was used to assay telomerase activity of H22 cells. Resuhs：Caffeic acid Ge could induced H22 cells apoptosis and inhibit telomerase activity by different concentrations. Conclusion：Caffeic acid Ge could inhibit H22 cells telomerase activity and cell proliferation obviously and could also induce apoptosis.
