And this paper also shows the structure and parameters of the optical system. The Xenon light of super high voltage is used as interferential source. The position of it is on the focus of the reflector of ellipsoid surface. After reflecting, its lights form a collective point . This point and objective focus of collimation lens are superposition. Though the collimation lens, the beam of light become parallel lights. Then though the Coude Reflector and radiation system of special prism, the lights become a beam of light with 3 ° emanative angle.

该光学系统选用超高压氙灯作光源，使其位于椭球面反射镜的一个焦点上，发出的光线经椭球面反射后所形成的汇聚点与准直负透镜组的物方焦点重合，光束经准直系统后变为平行光束，此平行光束再经库德反射镜和特殊发散棱镜系统，形成具有3°发散角的发散光束，用来干扰敌方设备。

In fact, any factor which interfere the formation of the hexameric IL-6 receptor complex might inhibit or antagonize the effect of IL-6. These factors include the IL-6 mutant, sIL-6Rα mutant and soluble gp130, as well as their antibodies.

事实上，任何能干扰IL-6信号转导中异六聚体复合物形成的因素都可能抑制或拮抗IL-6的作用，其中包括IL-6的突变体分子、sIL-6Rα的突变体分子和可溶性gp130分子以及它们的抗体。

Glioma is still one of refractory disease in the neurosurgical field; the development of new primary and adjuvant treatment is vital. Recently, the gene therapy of glioma is developed rapidly and there are many methods about the gene therapy that include: suicide gene therapy, immunologic gene therapy, drug resistangce gene therapy, angiostatin gene therapy and so on. The sucide gene therapy is the most potential approach of antitumer, these nonmammalian genes encode enzyme that convert nontoxic prodrugs into highly toxic metablites. Cells transfected with suicide genes are targeted for specific negative selection, witch can be induced by administrtion of the corresponding produg. Among the enzyme/produg combinations, two of the best characterized system are herpes simplex virus thymidine kinase /ganciclovir and Escherichia coli cytosine deaminase /5-flourocytosine (5-FC). The formor can convert the antiviral nucleoside analogs acyclovir , ganciclovir to their nucleoside monophosphate derivatives, the monophosphate forms are subsequently phosphorylated by endogenus cellular kinases to triphosphates, these molecules are potent inhibitors of DNA synthesis.

近年来脑胶质瘤的基因治疗发展迅速，应运而生的方法有自杀基因、免疫基因、多药耐药基因以及抗血管生成基因等，其中自杀基因被认为是最有前景的基因治疗方法，它又称病毒介导的酶／药物前体疗法，是利用转基因技术将哺乳动物细胞中所不含有的自杀基因转入到哺乳动物肿瘤细胞中，该基因表达的产物可将无毒的药物前体转化为毒性药物，从而选择性杀伤该肿瘤细胞，常用的自杀基因有单纯疱疹病毒-胸苷激酶基因和大肠杆菌胞嘧啶脱氨酶基因，前者催化无毒性抗病毒核苷类似物如丙氧鸟苷、无环鸟苷等成为单磷酸核苷衍生物，然后在内源性细胞激酶作用下转化为具有明显毒性的三磷酸核苷，作为DNA合成链的终止剂和DNA合成酶的抑制剂，干扰细胞DNA的合成；后者编码的胞嘧啶脱氨酶可催化5-氟胞嘧啶（5-FC）脱氨成为5-氟尿嘧啶（5-FU），然后代谢为有毒性的5-氟尿嘧啶-5′三磷酸（5-FUTP）和5-氟-2′脱氧尿嘧啶-5′磷酸（5-FdUTP），5-FUTP通过与UTP竞争性结合而抑制mRNA和tRNA的合成，5-FdUTP则作用于胸苷合成酶，导致TMP衰竭而阻止DNA的合成，最终诱导肿瘤细胞凋亡。

The results of the examine indicated that Scirpus mariqueter disturbed the phosphorous distribution by drawing phosphate from sediments and microbial degradation which formed the horizontal and vertical concentrational grads.

实验结果表明，海三棱藨草通过根系对磷的吸收和自身有机质降解，在沉积物里形成了水平的和垂直的浓度梯度，干扰了磷的正常累积和迁移。

Increasing number of chemicals have been found to be estrogenic or possessing other endocrine disruptive effects. Among them are some organochlorine pesticides and other organochlorine chemicals, such as DDT and its metabolite p, p'-DDE, kepone, toxaphene, dieldrin, and PCBs, dioxins, and furans.

现在已经有越来越多的化学物被发现具有雌激素样作用或其它内分泌干扰作用，其中有相当一部分为有机氯农药或其他有机氯化合物，如滴滴涕及其代谢产物p，p'-DDE、开蓬、毒杀芬、狄氏剂以及多氯联苯、二恶英和呋喃类等。
