In summary, our results suggest that ANE increases micronuclei frequency, induces cell cycle arrest at G2/M phase, causes cytokinesis failure and accumulates hyperploid cells. The events are possibly associated with ROS production, actin filament disorganization and centrosome aberration.

故从本实验的结果，我们认为槟榔子萃取物会增加微核频，诱导细胞周期停滞於G2/M phase，造成细胞质分缺损与多倍体细胞的增多；而这些现象可能与活性氧的生成，actin filament 的常与中心体的变有关。

There are three categories of maturity indicators of organic matter in current petroleum industry to evaluate the degree of thermal evolution for source rocks, including: 1 optical indicators, i.e., vitrinite reflectance, bitumen reflectance, sporopollen color and thermal alteration index, conodont color alteration index, and reflectance of fossil fragments; 2 chemical indicators, i.e., the maximum temperature in pyrolysis of organic matter, methyl phenanthrene indicator, the atomic ratio of H/C, carbon isotope indicator, and biomarker indicators; 3 indicators of spectroscopy, i.e., the free radical concentration of kerogen, the average structural scale of aromatic nucleus of kerogen, and the laser-Raman spectrum of organic carbon.

摘 要：当前常用的有机质成熟度指标包括3大类：1 光学指标，包括镜质体反射率、沥青反射率、孢粉颜色、热变指数(thermal alteration index， TAI)、牙形石色变指数(color alteration index， CAI)和生物碎屑反射率；2 化学指标，包括有机质最大热解峰温度、甲基菲指数(methyl phenanthrene indicator， MPI)、H/C原子比值、碳同位素指标和生物标志物指标；3 谱学指标，包括干酪根的自由基浓度、干酪根芳核平均结构尺寸和有机碳激光拉曼光谱。

Results:Whith the time and doses of ART incubation extended, ART significantly inhibited the proliferation of SGC-7901 cells and the inhibited effect shows dose-and -time-dependent. Obvious changes of apoptotic morphology were observed by invert microscope, fluorescence microscope, scanning electron microscope and transmission electron microscope, they showed that cells had marked nuclear condensation or the fragmentation of chromation as well as apoptotic , mitochondrial edema and vesicle , with the time of incubation extended , the proliferation rate become slow and the volume became small and transformed. FCM assay indicated that most of the cells were arrested in Go/Gi and the apoptotic peak appeared. During the prolong of incubation time, the apoptosis rate was increased. At the same time, the number of S and G2/M phase cells were decreased. The result of TUNEL indicant that there are apoptosis and necrosis.

结果：随着药物浓度的增加和作用时间的延长，蒿甲醚对胃癌SGC-7901细胞的抑制作用呈时间和浓度依赖关系：在倒置显微镜、荧光显微镜、扫描电镜和透射电镜下可观察到典型的凋亡细胞的形态改变，表现为：核固缩或染色质边聚或凝聚成大块状，可见凋亡小体，线粒体肿胀增殖，严重的空泡化，随作用时间的延长，细胞增殖速度减慢，细胞体积缩小变形；流式细胞术显示胃癌SGC-7901细胞出现明显的凋亡峰，随着作用时间的延长，其凋亡率逐渐升高，细胞周期阻滞在G_0/G_1期，S及G_2/M期细胞数大量减少；流式细胞术TUNEL检测结果显示细胞凋亡和坏死同时存在。
