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。

Solanacearum related gene from potato may be carried outthrough the following ways: 1 abolish the effect of inhibitors in potatoextraction, and establish high performance PCR system of potato; 2 usemore pair of PCR primers; 3 compare suitable P. solanacearum resistantand sensitive variety by AFLP technique.

通过病理学观测及组织生化指标的检测(SOD、MAD、GSH一PX、Hyp)，说明莲子心酚性总碱对博莱霉素致大鼠肺纤维化有一定治疗作用，可能的作用机制：降低肺纤维时胶原含量；抑制肺成纤维细胞的增殖；抗自由基和抗脂质过氧化作用及提高了机体内GSH一Px含量。

IDO inhibits the proliferation of eukaryotic intracellular pathogens or tumor cells by depriving them of tryptophan. IDO has been targeted for neurological disorders: it causes decrease of serotonin level in the brain resulting depression, and it causes the accumulation of neurotoxic quinolinic acid. IDO plays a key role in the suppression of T cell response and antitumor immune, it induces immune tolerance to embryo and explant.

IDO可通过降低微环境中色氨酸的浓度而达到抑制病原微生物增殖的作用； IDO与神经系统疾病也密切相关，它能降低5-羟色胺的水平而导致抑郁，也可造成脑中喹啉酸等具有神经毒性的代谢产物的累积； IDO在抑制T细胞免疫和抗肿瘤免疫、诱导母胎免疫耐受和移植物免疫耐受中均发挥重要的代谢性免疫调节作用。

The SPECT imaging of ~(99)Tc~m-GEBP11 can show the tumor mass clearly and ~(131)I-GEBP11 has anti-tumor effect with weak toxicant and secondary effect, which is the foundation for them to develop nuclide probe or radiotherapeutics drugs targeting to tumor vasculature.3. GEBP11 can inhibit angiogenesis, which comes true probably through its inhibition effects on the proliferation, invasion, migration and adherence of ECs.

1、GEBP11具有活体内胃癌血管靶向结合的能力，它与胃癌血管内皮细胞膜受体特异结合后可被内化。2、~(99)Tc~m-GEBP11 SPECT成像能较好地显示体内肿瘤灶，~(131)I-GEBP11具有明显的抗肿瘤效应及较弱的毒副作用，为开发肿瘤血管成像核素探针及受体放射治疗新药奠定了基础。3、GEBP11具有抑制胃癌血管生成的作用，这可能通过抑制ECs增殖、基质降解及迁移、粘附能力实现。
