Hybrid\\|pencil beam model,which has been obtained by embedding the bipartition model into Fermi\\|Eyges multiple\\|scattering theory,shows the potential broad prospect in clinic because of the good calculation accuracy and efficiency.

d+ k$？' o1 |将双群模型计算的宽束电子的能量沉积与Fermi Eyges理论的侧向解相结合来构造电子笔束模型，即混合笔束模型。由于混合笔束模型的计算精度和效率较好，并且适用范围较大，因此，混合笔束模型展示了在放射治疗临床应用上的可能性。

Abstract］ Background and purpose:The imaging of the skull base is challenging in nasopharyngeal carcinoma, through studying visualization and the appearance of foramen ovale,foramen rotundum,foramen spinosum,hypoglossal canal and nerve which can be identified on registration of CT and MRI for nasopharyngeal carcinoma, in order to define the target volume of nasopharyngeal carcinoma in radiotherapy planning.

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。
