        摘  要   目的:探讨钩吻总碱(TAG)抑制人结肠癌细胞增殖及血管新生的作用。方法:体外培养人结肠癌细胞HT-29和人脐静脉
        内皮细胞(HUVEC),经低、中、高剂量TAG(40、80、120 μg/mL)干预后,使用倒置荧光显微镜观察两种细胞的形态,采用CCK-8法
        检测两种细胞的存活率,采用流式细胞术检测HT-29细胞的周期变化情况,采用划痕试验、Transwell侵袭试验和管腔形成试验检
        测HUVEC的迁移率、侵袭率和管腔数量。结果:与空白组比较,TAG各剂量组HT-29细胞和HUVEC均有不同程度的减少,并可
        见死亡细胞,两者存活率均显著降低(P<0.05或P<0.01);TAG各剂量组G2/M期HT-29细胞比例以及中剂量组G0/G1期细胞比例
        均显著升高,而TAG各剂量组S期细胞比例以及高剂量组G0/G1期细胞比例均显著降低(P<0.05或P<0.01);TAG各剂量组HU-
        VEC的存活率、迁移率、侵袭率均显著降低,4~24 h各时间点管腔数量均显著减少(P<0.01)。结论:TAG可抑制人结肠癌HT-29
        细胞和HUVEC的增殖,可改变HT-29细胞的周期,并抑制HUVEC的迁移、侵袭及管腔形成。

        ABSTRACT    OBJECTIVE: To investigate the inhibitory effects of total alkaloids of Gelsemium elegans (TAG) on the
        proliferation and angiogenesis of human colon cancer cells. METHODS:Human colon cancer cell line HT-29 and HUVEC were
        cultured in vitro. After the intervention of low-,medium-,high-dose TAG(40,80,120 μg/mL),the morphology of the two cells
        was observed by fluorescence inversion microscope. The survival rate of HT-29 cells and HUVEC was detected by CCK-8 assay.
        Flow cytometry was used to detect HT-29 cell cycle. The migration rate,invasion rate and tube number of HUVEC were observed
        by scratching test,Transwell invasion experiment and tube formation experiment. RESULTS:Compared with blank group,HT-29
        cells and HUVEC were decreased to different extents in TAG groups;dead cells were observed,and the survival rate of both
        decreased significantly(P<0.05 or P<0.01). The proportion of HT-29 cells at G2/M phase in TAG groups as well as those at G0/G1
        phase in medium-dose group were increased significantly;the proportion of HT-29 cells at S phase in TAG groups as well as those
        at G0/G1 phase in high-dose group were decreased significantly(P<0.05 or P<0.01). Survival rate,migration rate and invasion
        rate of HUVEC were decreased significantly in TAG groups,and tube number was also decreased significantly at each time point
        during 4-24 h(P<0.01). CONCLUSIONS:TAG have inhibitory effect on the proliferation of human colon cancer HT-29 cells and
        HUVEC,can change HT-29 cell cycle,inhibit the migration,invasion and tube formation of HUVEC.
