The results show that, firstly, Stellera chamaejasme L, which rely on their developed axial root system in the 10～40cm soil layer to occupy the competitive priority of volume, length, surface area and so on, in the case of their adaptive faculty to poor surroundings resulting from fruit picking, trampling and overgrazing as well as with the phenomenon of restrained growth among various plants, gradually become the dominant plant in the herbaceous community; secondly, this kind of degraded grassland has not displayed any general characteristic of degradation such as surface exposure, accumulative quantity of vegetation reduced, water loss, soil erosion and so on, therefor, it should be dealt with distinguishingly; thirdly, if"Stellera chamaejasme L Killer"and"Oxytropis ochrocephala Killer"invented by CAS are taken advantage of respectively in the bloom period of Stellera chamaejasme L and at the beginning of florescence of Oxytropis ochrocephala bunge by ultra-low volume spray of 1. 05L/hm〓 and 1. 35～165L/hm〓 dosage separately, the death rates of poisonous herbs may achieve above 95% and 92% correspondently; fourthly, this technology with the characteristics of high work efficiency, exclusive selectivity and convenient operation, is safe to non-target plants and other animals, and has no toxic or side-effect to environment; furthermore, an execution of"Stellera chamaejasme L Killer"spray and a two-year grazing prohibition can be effectively applied on degraded grasslands of"Weed and Poisonous plants Type".

结果表明：狼毒凭借发达的轴根系在10～40cm土层中形成的体积、长度、表面积等竞争优势，以及对采食、践踏、过度放牧所形成的不良环境的适应能力和异株克生现象的存在，逐步成为草群中的优势植物；毒杂草型退化草地没有表现出地表裸露、植物蓄积量减少、水土流失等一般性退化特征，对该类草地的治理应区别对待；应用中科院研制的'灭狼毒'和'灭棘豆'分别在狼毒盛花期和黄花棘豆初花期，以1.05L/hm〓、1.35～165L/hm〓的施用量超低容量喷雾，毒草的死亡率可达到95％、92％以上；该技术具有工效高、选择性专一、灭效高、操作简便，对非靶标植物和其它动物安全，对环境无毒副作用的特点；采用喷施'灭狼毒'+短期禁牧措施，可以有效治理毒杂草型退化草地。

Majority of acute leukemias in infant, either acute lymphoblastic leukemia or acute myeloblastic leukemia, posses a chromosomal translocation affecting the 11q23 chromosome region which specifically inoles the mixed-lineage leukemia gene.1-3 Most pediatric leukemias with MLL rearrangement clearly hae a remarkably short latency.1,4 MLL gene rearrangement is also associated with secondary leukemias of patients preiously treated with the topoisomerase II inhibitors.4 The latency of these secondary leukemias is similarly ery short.4 Of note, the concordance rate of leukemia with MLL rearrangement in infant monozygotic twins approximates to 100%,1,4 and identical breakpoint in the MLL gene was shared in these pairs of identical twin infants with concordant ALL.1,4 Moreoer, the unique and clonotypic MLL fusion gene was detectable in neonatal blood spots for Guthrie cards from non-twined indiiduals who subsequently deeloped ALL.1,4 These obserations indicate not only that MLL fusion is generated in utero but also that MLL fusion proteins could be capable of inducing leukemic transformation with few, if any, secondary mutations.2,3,4 Greaes et al speculate that an MLL fusion protein somehow promotes rapid transition to full-blown disease in patients ia ery rapid clonal expansion, genetic instability, or inhibition of DNA damage repair.4 In general, for clonal expansion of malignancies, tumor cells often hae acquired strategies that escape immune sureillance of the hosts.5,6 Immune escape mechanisms also contribute to the failure of graft-ersus-leukemia effect after allogeneic hematopoietic stem cell transplantation.7 Therefore, leukemia cells could acquire some immune escape mechanisms during leukemogenesis.

绪论 绝大多数的婴儿白血病，不管是急性淋巴性白血病或是急性骨髓性白血病，在染色体11q23部位有染色体易位的情况；这个部位的染色体易位牵连了混合谱系白血病基因。大多数具有MLL基因重排的儿童白血病潜伏期明显短很多。MLL基因重排也和经拓扑异构酶II抑制剂治疗后的继发性白血病有关。这些继发性白血病的潜伏期类似地都非常的短。很重要的是，单卵双胞胎婴儿同时患有或同时免于MLL基因重排阳性的白血病的一致性接近100%；并且同样患有ALL的同卵双胞胎的MLL基因的断裂点是一致的。而且，这种独特的克隆特异性的MLL融合基因能够从那些得ALL的非双生个体出生时的血斑标本中检测到。这些发现表明MLL融合基因产生在胎儿还在子宫的是后，而且MLL融合蛋白能过和其他的基因突变一起诱导白血病的产生。Greaes 等推测MLL融合蛋白在某种情况下同过快速克隆增殖，遗传的不稳定性或是DNA损伤修复的抑制促使疾病迅速地全面爆发。恶性肿瘤细胞的克隆增殖通常已经获得了逃避机体免疫监视的能力。免疫逃避机制也归因于异体外周血干细胞移植后移植物抗白血病作用的失效。所以，白血病细胞在白血病的产生过程中可能获得了某些免疫逃脱机制。

Judging from the artistic representation that we may expect, the creators concentrate on the expression of elegant and spiritualistic inner world; the images are extremely beautiful; music refreshingly touching; human behavior and spiritual movement are manifested with fairy-tale like movie art, reenacting Anderson fairy tale in reality in front of the audiences; bringing the great spiritual heritage left by the great Danish fair-tale master, echoing and manifesting with the most in harmony in the new-wave Chinese movie.

从预期艺术表现手法来看，创作者们濯墨于表达优美而灵性的内心世界，画面将是无以伦比的美丽，音乐将是沁人心脾的动听，把人物的行为及其心灵的异动，以童话般的电影艺术手段加以表现，让安徒生式的童话以真实再现的面目出现在欣赏影片的观众面前，让丹麦的这位童话大师给我们留下的精神上的伟大遗产，在中国的这部新派优秀电影中给予最充分的和最和谐的共鸣与体现。

The bioassay results showed that the quaternary ammonium salt had a good intihtion against typical microorganisms such as heterotrophic bacteria,ammonifying bacteria,denitrifying bacteria and nitrosation bacteria with its inhibition rate was above 90%. Inhibition of the quaternary ammonium salt to fungi and sulfate reducting bacteria was above 85% after 30 min. Inhibition of the quaternary ammonium salt to black mold was about 84% after 30 min,and the to algae was totally inhibited after 24 h.
