Two specieses, Lycoris radiate and Lycoris aurea, were selected for the studying of artificial propagation in vitro. A few specieses of Lycoris, from the southeast area of China and part of locations in Japan, were chosen to research their karyotype differentiation and to measure their genetic diversity by ISSR analysis. The results could be summarized as follows.1. The vegetative propagation conditions of Lycoris aurea and L. radiate in vitro was studied by two-scaling. Different illuminate condition had an effect on the bulblet formation rate. To the species of L. radiate, the rate was higher in the state of 16h 800-12001x illumination than in the darkness. The medium also affected the new bulblet formating rate. When the culture was MS medium 0.2 mg/L NAA 4 mg/L 6-BA, the bulblet formationg rate of L. aurea was 220%;at the same time, when the medium was MS 0.2 mg/L NAA 2 mg/L 6-BA, the rate of L.

本研究选择西南部分地区及日本的几个石蒜品种，从细胞学和DNA分子角度，分析了它们的遗传多样性水平和遗传结构状况，对红花石蒜和忽地笑的离体繁殖技术进行了初步研究，得出如下结论： 1 进行了红花石蒜和黄花石蒜双鳞片快速繁殖条件的研究，结果表明：红花石蒜在16小时800-1200 lx光照下比黑暗条件下出芽率要高；黄花石蒜在MS NAA0.2mg／L 6-BA4mg／L下出芽率为220％，红花石蒜在MS NAA0.2mg／L 6-BA2mg／L下出芽率为108％；NAA比IBA有利于石蒜生根；硅藻土显著提高黄花石蒜双鳞片出芽率，活性炭起抑制作用；6％蔗糖浓度有利于红花石蒜小鳞茎增重，MS 6-BA4mg／L NAA0.5mg／L培养基有利于小鳞茎增殖，切割一刀比两刀有利于小鳞茎增殖。

Result: Rhesus BMSC can be got in mass by density gradient centrifugation.; Rhesus BMSC can adhere to PLGA fiber quickly after plant and its growth , division ,proliferration is good; Some cells arrange like rosary on PLGA fiber surface, some cells still form the catenate or flaky cell bridge joined among PLGA fiber.

结果：采用密度梯度离心的方法可得到大量增殖能力强的猕猴骨髓基质干细胞；接种后的骨髓基质干细胞很快粘附于PLGA纤维上，生长、分裂、增殖良好，在PLGA纤维表面形成串珠样排列，部分细胞还形成连接在PLGA纤维间的链状或片状细胞桥。

The theory is cell kinetics and mechanism of drugs.

主要是根据细胞动力学原理和药物的作用机理分析，如果把药物集中应用，一方面只是一过性的杀灭增殖期的白血病细胞，对静止期细胞影响不大，另一方面对正常细胞造成较大损伤，而如果药物作用于几个细胞增殖周期，对白血病细胞进行几个循环的打击，会清除更多白血病细胞，而对正常细胞损伤较小。

CO2 can inhibit the proliferation and promote the apoptosis of the endometrial cancer cells with distending pressure from 40 mmHg to 100 mmHg. The higher the pressure is, the more obviously CO2 can inhibit the proliferation and promote the apoptosis of the endometrial cancer cells.

二氧化碳在40~100 mmHg压力范围内，能够抑制子宫内膜癌细胞的增殖，促进子宫内膜癌细胞的凋亡，且随着压力的增加，二氧化碳对子宫内膜癌细胞增殖抑制和促进凋亡作用愈明显。

The effect of CuBr laser power and irradiating time on the proliferation of hematopoietic cells was studied, it is helpful to know the proliferative mechanism of hematopietic cells.

本文介绍了CuBr激光的功率和照射时间对造血细胞增殖作用的影响，有利于对激光刺激造血细胞增殖机制的认识。

After introduction of the recombinant plasmid into BME cells, the capability of proliferation was obviously enhanced and the DNA content was changed, the cell proliferation lifespan was elongated to 13 population doublings to control.

导入STAT3基因后，细胞增殖能力增强，染色体倍数发生变化，细胞的增殖寿命较对照细胞延长了13代，表明导入STAT3基因后，能延长体外培养的牛乳腺上皮细胞的寿命。

In a word, mad1 gene or mad1 combining with c-myc gene could inhibit TCCB cell proliferation but not normal fibrocytes in vitro and in vivo, which targeted hTERT, suppressed its transcription and expression, and down-regulated the expression of cyclin D1 and TGF-β1, to further block the cell cycle, change cell morphology and suppress proliferation.

综上所述，mad1基因或mad1联合c-myc基因能在体内外抑制TCCB细胞的增殖，但对正常成纤维细胞无明显影响，二者以hTERT为作用靶点，抑制其转录和表达，并下调cyclin D1和TGF-β1的表达，进而阻止细胞周期、改变细胞形态和抑制癌细胞的增殖。

It is suggested that CDK2 might progress the proliferation of endothelial cells in human proliferative hernangiomas; while p27(superscript Kip1) might inhibit the proliferation of endothelial cells in involuting hemangiomas.

p27(上标 kip1)能抑制血管瘤内皮细胞的增殖，在血管瘤的退化过程中起了重要作用；而CDK2能促进血管瘤内皮细胞增殖，在血管瘤的增生过程中起了重要作用。

Monitoring shows that through 8 years of fishing and proliferation released, Lake fishery resources and ecological environment improvement, especially through the proliferation of releasing the lake fish resources increased significantly improve population structure, the catch of Lake grass carp, silver carp and bighead carp, such as "Four fish" to increase the ratio of nearly 6 percentage points

监测显示，通过8年来的禁渔和增殖放流，鄱阳湖渔业资源和生态环境得到改善，特别是通过增殖放流，湖区鱼类资源量提高，种群结构改善明显，鄱阳湖的渔获物中草鱼、鲢鱼和鳙鱼等&四大家鱼&的比例提高了近6个百分点。
