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 tripolar structure SST anomalies over the North Atlantic, which also appears at the interannual scale with a spectral peak at 3—4 years, are mainly resulted from the barotropic driving of the NAO like atmospheric forcing, and thermal process plays a dominantrole in this process. When the NAO is strong, the westerly weakens over the midlat itudes; both the sensible and the latent heat flux release from the ocean tend to decrease, which warms the ocean and leads to positive SST anomalies. Over the sub polar region including the Labrador Sea, a stronger NAO is associated with a deeper Icelandic Low; the high latitudes originated colder air then blows over the ocean surface, the air-sea temperature difference become larger, and the se n sible heat flux loss from the ocean increases, which subsequently leads to colder SST anomalies.

分析表明，模式中三核型SST异常的产生，主要来自大气的强迫，NAO增强，中纬度大洋上的西风减弱，海洋感热和潜热通量损失减少，中纬度大洋得到的净热通量增加，导致SST出现正距平；在包括Labrador 海在内的副极地大洋，NAO增强、冰岛低压加深，气旋性环流增强，来自高纬度的冷空气吹过洋面，海气温差加大，大洋的感热通量损失增加，SST降低。
