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。

Develop a software for image registration of the functional SPECT/PET information to anatomical CT images, thereby, used in the diagnosis of rectocolonic tumor and increased their sensitivity and specificity.

开发图像融合的通用软件，将SPECT、PET功能图像与显示细微结构的CT图像融合，用于结直肠等肿瘤的诊断，以提高了肿瘤诊断的敏感性和特异性。
