It is major work to present the tectonic time duration system of the strain rate method, which is an original exploration.(1) Principle: Its basis is the stress and strain rule depending on strain capacity in steady-state stress field, but not the radioactive decay law depending on radiation dose in invariable radiation field. This can be simplified as a process of differential stress-strain rate-strain capacity-time duration calculating.

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。

At the experimental intensity of 20W/cm^2 and in the dose range studied (0.00, 0.24, 0.48, 0.72, 0.96 and 1.20kJ/m^2), both the population number and growthrate was the highest in the control and decreased with the increment of UV-B radiation. In addition, the population number and growth rate of rotifer Brachionus urceus showed a similar tendency of decrease with the dose increase of UV-B radiation. Both of them could be used as an ideal biomarker for the enhancement of UV-B radiation.

实验表明，在本实验辐射强度(20W/平方公分)和剂量范围内（0.24、0.48、0.72、0.96和1.20kJ/平方人公尺）壶状臂尾轮虫的种群数量和种群增殖率均以对照组最高，各UV-B辐射处理组则随UV-B辐射剂量的增大而呈一致性减小，说明该种群的种群数量和种群增殖率随UV-B辐射的增强显示一致性的影响，两者都可以作为大气UV-B辐射强弱的生物指标。

Results:weijian obviously shortened the latent period of erection in castrational rats after electric stimulus and the latent period of coitus in castrational mice,increased coitus times in castrational mice,increased the appearance rate of sperm suppository in copulated female mice. the acute toxicity tests showed that the half lethal dose(ld50) of weijian was 901.53 mg/kg and 319.60 mg/kg, the long-term toxicity tests showed that large dose of weijian slightly increased the level of glutamic pyruvic transaminase and decreased the glucose,triglyceride and cholesterol of blood, while had no effects on other biochemical factors.

Should this modest increase in dose not be sufficient to alleviate symptoms, we double the prednisone dose. The disease flare is allowed to subside and the taper is reinstituted at a slower rate or at smaller decrements (eg, one-half of the original decrement). There are, to our knowledge, no data supporting one method or another.

如果这种剂量适度增加不足以缓解症状，我们则把强的松剂量加倍，当疾病复发平息后，再重新开始缓慢减量（如每月1次）或减量少一些（如原来减少量的1/2），据我们的了解，尚无支持一种或另一种方法的资料。
