To further investigate their roles in cell proliferation apoptosis and differentiation, three human leukemia cell lines (K562, U937 and HL60) exposed to various concentration of hexamethylene bisacetamide, a potent inducer of differentiation of transformed cells both in vivo and in vitro, were used as an in vitro model for the study of cell proliferation, differentiation and apoptosis.

为了进一步研究cyclin A和p21在白血病细胞增殖，分化，凋亡中的作用，我们用在体内，外均有抗肿瘤作用的药物六亚甲基二乙酰胺在体外抑制白血病细胞株K562，U937和HL60增殖，诱导其分化，成功地建立了与药物干预浓度呈剂量-效应关系的，具有不同增殖，分化，凋亡状况的实验细胞模型。

In the first part of this thesis, the reasons of develop LED biology light source have been discussed from the effects of non-concern homochromy light on cells, the mechanisms and non-resonance characters of photobiomodulation on cells, the biological information model of photobiomodulation of low intensity laser proposed by Professor Liu TCY.

论文的第一章，首先从非相干单色光的细胞生物效应、光生物调节作用机理、光生物调节中非共振作用的特征、以及生物信息模型等几方面，论述和确立了研制LED生物光源的理论依据。

Pharmacological results also indicated that the carbonyl and imino of Z-47 are important to its marked antiinflammatory and analgesic activity. The activity will be reduced or abolished with Z-47 converted to oximes or/and acetamides.

药理结果还表明，Z-47结构中的羰基和仲胺基对Z-47的显著抗炎镇痛作用具有重要的贡献，将Z-47羰基变成肟或／和将Z-47仲胺基酰化都会造成抗炎镇痛作用的降低甚至是丧失。

Seauckthorn juice can be appropriate drinks afer the diluting, which could block the N-nitroso Synthesis and also can block N-dimethylnitrosaminewhich can lead to cancer.The flavone of Seabuckthorn contains coumarin, isocoumarin, furan coumarins, lignin, as well as bitter polyphenols, 5 - serotonin, which are benefited for anti-cancer.

沙棘汁经稀释成宜引用的浓度后，能阻断N-亚硝酸的合成，另外沙棘汁对致癌物N二甲基亚硝胺也有阻断与防护的作用；沙棘黄酮中含有香豆素，异香豆素，呋喃香豆素，苦木素以及多酚类，5-色胺等具有综合抗癌作用的成分。

During these events, the potassic volcanic rocks of Oulituozi were produced during extension stage of the rift with subsequent fractional crystallization and derived from basaltic magma.

欧利坨子富钾质火山岩的形成是裂谷期岩石圈伸展作用的产物，是玄武质岩浆经过大比例分离结晶作用的产物，可能与晚中生代太平洋板块俯冲残片的部分熔融有密切关系。

During these events, the potassic volcanic rocks of Oulituozi were produced during extension stage of the rift with subsequent fractional crystallization and derived from basaltic magma. The genesis of the volcanic rocks possibly had a close relation with partial melting of the subducted slab of Pacific Plate oceanic crust.

欧利坨子富钾质火山岩的形成是裂谷期岩石圈伸展作用的产物，是玄武质岩浆经过大比例分离结晶作用的产物，可能与晚中生代太平洋板块俯冲残片的部分熔融有密切关系。

The result suggests that IGF-IR and EGFR might be involved in mediating the effects of energy intake on the development of reproductive system in prepubertal gilts.

结果表明：日粮能量水平显著影响初情期前母猪卵巢上两种生长因子受体的表达，高能量对表达有促进作用，有利于两种生长因子作用的发挥，从而利于生殖系统的生长发育；因此，IGF-1R和EGFR可能参与介导能量摄入对初情期前母猪生殖系统发育的影响。

The observation of morphogenesis of flower buds in this stage shows that this early floral buds have only perianth primordia at most, and no sex organ primordia yet.

综上所说，黄瓜的性别表达过程应该是多激素共同作用的结果，并且每一种内源植物生长物质对黄瓜性别表达的作用应该有一定的阈值。

As it is well known that there is a real gap between foundation and soil. It is important to consider the nonlinearity of the process of contact, separate and recontact between foundation and soil.

基础与地基之间存在着实际上的缝隙，在共同作用过程中存在接触、脱开再接触的过程，真实地反映共同作用的这种接触非线性性状是相当重要的。

Acyclic retinoid, a novel synthetic retinoid, was reported to prevent the recurrence of human HCC after surgical resection of primary tumors, but the molecular mechanisms are yet to be el...

本研究的目的是，明确ACR预防HCC术后复发的分子作用机理，和其作用的标的分子，并以此为线索寻找出更有效的HCC治疗方法。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.

这是凯特，那个是爱朗。
