(1) cerebral ischemical reperfusion injury rats'limbs motor function is variable. Acupuncture could promote lims'functional recovery.(2) PCNA masc cells is visible in cerebral ischemical semidarkness region. There is cell regeneration phenomenon. Acupuncture could strengthen injury region's PCNA expression, could profit injury recovery and functional reconstruction.(3) In ischemia semidarkness region for the model group and acupuncture group, PCNA masc cells percentage of 14days group is lower than 7days group. Along with the recovery of injury, cell multiplication is weaken.(4) In cerebral ischemia semidarkness region, there is VEGF masc cells and regeneration phenomenon. Acupuncture could strengthen injury region's VEGF expression, could profit protection after injury and blood vessel regenerate.(5) In ischemia semidarkness region for the model group and acupuncture group, VEGF masc cells percentage of 14days group is lower than 7days group. Along with the recovery of semidarkness region, ischemia and anoxemia state is getting improved, and VEGF is reduce.(6) As there are PCNA and VEGF masc cells in brain injured region, we could conclude that, after brain ischemical reperfusion injury, there are blood vessel regeneration phenomenon. Acupuncture could promote blood vessel regeneration, recovery blood supply sufficiently and quickly, and promote the recovery of brain injury region.(7)The VEGF masc cells percentage of inhibitor group is lower than acupuncture group. It state that the effect of acupuncture promote VEGF is partly depend on the existing of eNOS.
实验结论:(1)脑缺血再灌注损伤后大鼠的肢体运动功能发生改变,针刺可以促进肢体功能恢复;(2)脑缺损伤区可见PCNA阳性细胞,存在细胞再生现象,针刺可以增强损伤区PCNA的表达,有利于损伤的修复和功能重建;(3)针刺组和模型组14d时缺血损伤区PCNA阳性细胞百分比低于7d组,随着损伤逐渐得到修复,细胞增殖现象减弱;(4)脑缺血损伤区可见VEGF阳性细胞,存在内皮型细胞再生现象,针刺可以增强损伤区VEGF的表达,有利于脑损伤后保护和缺血区血管再生;(5)针刺组和模型组14d时缺血损伤区VEGF阳性细胞百分比低于7d组,随着缺血损伤的修复,缺血缺氧状态得到改善,产生的VEGF减少;(6)由于脑损伤区同时出现PCNA阳性细胞和VEGF阳性细胞,前者是增殖细胞的标志,后者是促进血管再生的重要因子,可以推断,脑缺血再灌注损伤后脑内存在血管再生现象,针刺可以促进损伤区的血管再生,更迅速而充分的恢复损伤区的血供,促进脑损伤区的修复;(7)抑制剂针刺组脑损伤区VEGF阳性细胞百分比与针刺组相比有不同程度的降低,说明针刺促进缺血损伤区VEGF表达部分依赖eNOS的存在。

The results showed that (1) the positive staining of ChAT was obviously observed in the cells of the three kinds of human pituitary adenoma, however, it was lower than that in normal human pituitary gland;(2) ACh had a similar effect on the proliferation of the three kinds of human pituitary adenoma cells. ACh at 0.1~10 μmol/L decreased the [3H]TdR incorporation and the MTT A value in a dose-dependent manner. At the same time, ACh decreased the ratio of S or G2 phase pituitary adenoma cells significantly, but increased the ratio of G1 phase pituitary tumour cells markedly;(3) the effect of acetylcholine on the proliferation of human pituitary adenoma cells was inhibited by atropine, but not by tubocurarine;(4) ACh had no effect on the apoptosis of human pituitary adenoma cells cultured in vitro.

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。

Results The activation of NF-κB, proliferation response, and expression of IL-4 and I L-5 mRNA and protein in T lymphocytes stimulated by PMA were significantly hig her than those of their blank control (P.01), while those indexes of T l ymphocytes stimulated by PMA and PDTC simultaneously were significantly lower th an those stimulated by PMA alone (P.01). The apoptotic index of T lympho cytes stimulated with PMA were significantly lower than that of their blank cont rol (P.01), and the apoptotic index of asthmatic guinea pig T lymphocytes stimulated with PMA and PDTC simultaneously were significantly higher than that stimulated by PMA alone (P.01). The significant positive correlations w ere found between the activation of NF-κB and the proliferation (r=0.64, P.001), and the expression of IL-4 and IL-5 mRNA and protein of T lymph ocytes, respectively (r=0.55-0.68, P.001). There was also signific ant negative correlation between the activation of NF-κB and apoptosis of T l ymphocytes (r=0.62, P.001). Conclusions NF-κB may participate in the signal conduction of PKC regulated proliferation, apoptosis and expression of IL-4 and IL-5 of T lymphocytes in asthma.
