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。

This product can increase immunity of livestock and poultry, enhance the activity of phagocyte, which otherwise can not be performed by normal microorganism flora parasitized in animal intestinal tract.

禽畜机体内正常的微生物菌群对机体的免疫系统具有重要的诱发作用，本品可提升动物肠内免疫系统细胞，使一般非特异免疫功能得到协调和提高，加大吞嗜细胞的活性，这些并非原宿于禽畜肠道内微生物菌系所能达到的。

The therapy of protection of liver function is very necessary: diammonium glycyrrhizinate can recover the non-specific damage of liver cells, Fufangdanshen can improve the microcirculation of liver, and tiopronin and reduced glutathione has the unique function to recover liver damage caused by fat invasion. Of 168 cases, 60 cases (35.7%) show exacerbation of liver function after using fat-reducing drugs for 1-2 weeks. Of 41 cases (male 36 and female 5) with the complication DM2, 58.5%(24/41) of cases also show exacerbation of liver function after using sugar-reducing drugs.

保肝治疗非常必要，甘草酸二铵有修复非特异性的肝细胞损伤的作用，复方丹参可以改善肝脏微循环；硫普罗宁或还原性谷胱甘肽，对于脂肪肝之由于脂肪浸润引起的肝细胞损伤的修复有独到的作用。168例中有60例（35.7%）因用降脂药物1～2周出现肝功能异常的加重；合并2型糖尿病的41例（男36例，女5例）患者中有58.5%(24/41)的人用降糖药物后也出现肝功能异常的加重。

MNSFP was a previously identified novel implantation-related factor that needed to be further investigated in our lab, and is a lymphokine produced by suppressor T cell.

MNSFD是本实验室正在研究的另一个新发现的着床相关因子，它是一种由抑制性T细胞合成的具有非特异性免疫抑制作用的淋巴因子，因其能抑制IL-4的分泌和Th2细胞的产生，所以推测其可能与母胎间免疫耐受的形成有关，但有待于研究证实。

It is necessary to develop a protein-free media for oocytes maturation that can prevent zona hardening. In this study, immature macaque oocytes were cultured in modified CMRL media alone or CMRL with either bovine calf serum or PVA for 24 hours. Also, in vivo matured oocytes were cultured in CMRL supplemented with PVA or serum for approximately 6 hours.

我们在本研究中，将非成熟的猕猴卵母细胞分别在改良的CMRL，或在含有胎牛血清或聚乙烯醇的改良CMRL培养基中培养24小时；同时，将体内成熟的卵母细胞分别在含有PVA或者胎牛血清的CMRL中培养6小时，然后进行体外授精，比较各组间精子穿透率或受精，以及胚胎发育情况。

I believe that the existence of natural selection decide the way of life, there are biological or cell biological membrane is the first origin of life-life product of evolution and development; no biological membrane that is non-cell biology is the origin of life re-evolution of life and development.

笔者认为自然选择决定生命存在的方式，有膜生物即细胞生物是生命最初起源的生命体进化和发展的产物；无膜生物即非细胞生物是生命再度起源的生命体进化和发展的产物。

Cellular fibronectin is a kind of non-collagen glucoprotein. It is present mostly in periodontium, taking part in many physiological functions, such as cell junction, proliferation and differentiation, reparation and arrangement of epithelial tissue, immunoregulation of organism.

细胞纤连蛋白是一种具有生物学活性的非胶原糖蛋白，大量的存在于人的牙周组织中，排列规律，参与机体细胞的连接黏附、增殖分化和上皮组织的修复以及机体免疫调控等多种生理活动，是维持牙周附着的主要物质。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.
