非特异性的

The clinical and laboratory findings of 2197 cases of systemic lupus erythematosus were reviewed and analyzed to reveal the abnormal incidence of each item and their value and specificify for the diagosis of the disease,Accor- ding to the realistic conditions of our country and the experience of many authors, a new set of diagnostic criteria for SLE was established and systematized into a computer program.

本文通过复习2197例SLE临床及实验室资料，分析各项目发生的异常率、早期表现率和对诊断的特异性，结合国内具体情况和多数学者的经验，综合分析拟定SLE评分诊断标准，并编成计算机诊断程序。经223例非SLE和92例SLE病例资料验证，其特异性为91.9％，敏感性达95.7％。

Fluorescein isothiocyanate labeled polyclonal goat antihuman immunoglobulin antibody was added, and flow cytometer was used to detect bead-platelet-associated autoantibodies-antihuman immunoglobulin antibody complex. Results The fluorescene ratio of four monoclonal antibodies was significantly different (P.01) between the idiopathic thrombocytopenic purpura patients and either the non-ITP patients or the normal controls. If the upper limit of normal control was set as cutoff value, ratios of greater than 1.37, 1.24, 1.48 and 1.19 were considered positive for the four monoclonal antibodies respectively. The flow cytometric bead assay had an overall sensitivity of 73.17% and a specificity of 94.29%. The overall sensitivity was significantly higher (P.05) than that of modified indirect MAIPA and that of using single antibody.

Social stress such as the quickened social rhythm, increasingly furied work competition, make people have more and more mental burdens. Stressful life events have high affinity to depression, this suggests that the social stress could be important in the pathogenesis of some depressive disorders.

应激是生物在生存过程中受到各种各样的刺激后产生的非特异性适应性反应，随着现代生活节奏的加快、工作竞争激烈等各种社会应激因素的加剧，抑郁症的发病率逐年升高，应激性生活事件与抑郁症的发病存在密切关系，应激已成为诱发抑郁症的重要因素。

Four field strains of infectious bronchitis viruswere isolated from chicken kidney, trachea and lung of the young layer flocks in some regions of Shaanxi province. Biological characterizations of the virus were investigated by virus pathogenicity to chicken embryo and healthy chickens, hemagglutination test, hemagglutination inhibition test, dwarfing embryonated chicken eggs, electron microscopy and reverse transcription polymerase chain reaction. It demonstrated that allantoic fluid of each passage virus could hemagglutinate chicken red blood cells by treatment with 1% trypsin. The standard positive serum to IBV could inhibited the hemagglutination. The isolates could make respiratory and kidney diseases in chickens.

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。

In addition, the influences of BIS on the activities of lymphocytes in vivo and in vitro were studied, including the blast transformation of lymphocytes, the number of acid α-naphthyl acetate esterase positive lymphocyes, the cytostatic effect of hepatic LGL against hepatoma cells, in older to provided the most adequate scientific foundation for the best application of hepatoma immunotherapy.

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。
