CFA The isotopic test of CFA consisted of intravenously injecting 99mtechnetium-labeled albumin, inducing venous compression on a hindquarter, and measuring radioactivity externally on the limb before, during, and after removal of venous compression.

同位素测试包括静脉注射99m technetium 标记的白蛋白，以及后段静脉的压缩，并於肢体外测量静脉压缩前，静脉压缩中和去除静脉压缩后的放射性活性。

The level of tumor necrosis factore alpha, interleukin-6 (IL-6) and interleukin-8 (IL-8) were evaluated using ELISA method. Western blotting was used to detect the protein expression of protein kinase B and lipid phosphatase PTEN. Immunoprecipitations and radioactivity of γ〓P incorporated into its specific substrate histon H〓B was utilized to determine the PKB activation. Phosphate concentration released from PTEN-specific substrat diC16PIP3 was assessed using green reagent method.

以细胞计数、噻唑蓝比色法测定细胞增殖能力，酶联免疫法检测培养上清液中细胞因子TNFα、IL-6、IL-8水平，Western免疫印记定量蛋白激酶B、蛋白磷酸酶PTEN表达水平，免疫沉淀、特异底物组蛋白H2Bγ〓P掺入量测定PKB活性，特异底物dic16PIP3脱磷酸绿色试剂法反应PTEN活性。

Hazardous solid wastes are substance with toxicity, inflammability, chemical reactivity, infectivity and radioactivity, which make the hazardous solid wastes the potential pollutions and harms to the atmospheric, aquatic, edaphic and ecological environments.

危险废物是指具有毒害性、易燃性、腐蚀性、化学反应性、传染性和放射性的废物，危险废物的特征决定了其对大气、水体、土壤等生态环境破坏存在长期和潜在的隐患。

Results The PET/CT imaging was performed for 62 patients including 7 cases with central bronchial carcinoma, and 55 cases with peripheral lung cancer. 59 cases with confirmed diagnosis, the diagnostic accuracy rate was 95.16%. Some abnormal enrichment can be seen by 18F-FDG PET/CT. The largest SUV is 1.0～22.3. Radioactivity intussuscept can be seen by 11C-MET and PET-CT, and SUV is 0.5～4.9. Vessel bunch is available by CT enhancement scan that can clear the borderline of lession. Sublobe,spicule sign,depressed pleura,and bronchia obstruction can be seen by HRCT.

结果 62例肺癌患者中，中央型肺癌7例，周围型肺癌55例，明确诊断59例，诊断率95.16%。18F-FDG PET/CT检查见病灶有不同程度放射性异常浓聚，最大SUV1.0～22.3； 11C-MET PET/CT检查的病灶均见不同程度放射性摄取，SUV0.5～4.9；CT增强扫描病灶边界清晰，明显强化，可见血管"集束征"， HRCT检查见病灶有分叶、毛刺征、胸膜凹陷征及支气管阻断。
