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。

Results All17patients had reiteratively blood in stools.The longest medical history of these patients is of3years,the shortest is of2months.8cases showed symptoms of stomachaches;2cases showed symptoms of peritonitis.3cases resulted in positive tests in the radioactive scanning.Of the rest of the patients,1case showeda positive test in the selective arterial angiographies.Of the17patients,12recovered completely after the operation.And no recurrence was found in the following3～5years.5patients died of the recurrence of tumor and metastasis.

结果 17例均有反复次便血，病史最长3年，最短2月，8例伴有腹痛，2例伴有腹膜炎体征，3例伴有腹块。3例核素扫描检查均是阳性，4例选择性血管造影1例阳性。17例病员无1例术明确原发病，其中15例剖腹探查直接找到病因，2例术中结合内镜找到出血原因。17例中12例经手术治疗痊愈，随访3～5年无复发。5例死于肿瘤复发转移。

The currently acceptable screening test is the spart albumin/creatinine ratio, to be done in the morning preferablely, and if you are using radioactive agents to measure that, you can't just do one time; you should do twice and ideally three times, over the following a couple of weeks.

目前能够接受的筛选方法是白蛋白/肌酐比，且在清晨行此试验较佳。如果采用核素成像的方法，不能只行一次检查，至少做两次，理想情况是做三次。

The currently acceptable screening test is the spart albumin/creatinineratio, to be done in the morning preferablely, and if you are usingradioactive agents to measure that, you can't just do one time; youshould do twice and ideally three times, over the following a couple ofweeks.

The patients were received intervenous drop infusion of 153Sm-EDTMP and ibandranate in treatment group (n=48). The patients were received therapy with 153Sm-EDTMP in control group (n=48). The different of effect of odynolysis, locomotor activity, improvement of quality of life, recovery of osteolysis, toxical and adverse reaction between two group was compared.

96例肺癌骨转移患者随机分为2组，153Sm-EDTMP内放疗加伊班膦酸钠静脉滴注48例，单用153Sm-EDTMP核素治疗组48例，比较2组止痛效果、活动能力、生活质量改善、溶骨病灶的修复及毒副作用。

Objective: To assess the value of transthoracic echocardiography in the diagnosis and treatment of acute pulmonary embolism.

目的：探讨经胸超声心动图在急性肺栓塞诊断与治疗中的价值。方法：对经临床综合诊断（包括核素肺灌注扫描或CT血管造影）确诊为急性肺栓塞的患者46例进行经胸超声心动图检查。

Conclusion］ECT plays an important role in diaognosing the spinal tuberculosis and the tuberculose focus of body can be found and has the guidance for doctors to formulate the therapeutic regimem of spinal tuberculosis.

结论］核素全身骨显像在脊柱结核诊治中有重要价值，可以发现全身骨与关节多个结核病灶，对制定脊柱结核的治疗方案有指导作用。

Using nucleus tracer technique to quantificationally research soil erosion has unsubstituted advantage, such as exactness, speediness, precision, and so on.

利用核素示踪技术定量研究土壤侵蚀速率具有常规技术无可比拟的优势，准确、快速、精确度高，越来越受到研究者的重视。
