通过电子显微镜观察降解后膜的表面，结果表明：通过长期驯化的F4和p.ch菌株，都能使PET膜表面产生明显刻蚀孔洞；且在富氧的条件下，以TA为共代谢基质降解PET膜，在一个月内能将PET膜表面刻蚀出较大空洞。

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。

The results showed the crystallinity of the modified PET decreased with the increase of the content of NPG, but the heat shrinkability was improved obviously. Amorphous polyester material that would not crystallize under usual circumstances was obtained, which made the modified PET film to be able to achieve a high degree of orientation during stretching, and it was heat shrinkable when the ambient temperature was higher than its T the effects of different drawing temperature and DR on heat shrinkage of copolyester film was discussed.

结果表明，通过NPG共聚改性的PET的结晶能力随NPG用量的增加而降低，热收缩能力有了明显的提高；无定型区增大，获得了在通常情况下不能结晶的PET无定型材料，从而使改性PET薄膜在拉伸时保持较高的取向度，并在高于其T时发生解取向热收缩；拉伸温度、拉伸倍数等拉伸工艺对于聚酯薄膜的热收缩率有着显著的影响。

Methods Ninety NSCLC patients underwent curative surgical resection after integrated 18F-FDG PET/CT and chest breath-hold spiral CT examination. Two experienced radiologists blindedly staged all primary tumors in consensus by CT and PET/CT images.

90例经手术病理证实的NSCLC患者均于原发肿瘤切除术前行18F-FDG PET/CT和胸部屏气螺旋CT扫描，由两名有PET/CT诊断经验的影像医师采用双盲法分别根据屏气CT和PET/CT图像对肿瘤行T分期。

Often upstaging （ approximately 40%） due to PET and detected efficacy of PET was variant along with pathological histology pattern of lymphoma, the reliability （〉90% positive on PET） particularly was in DLBCL and Hodgkin＇s disease.

PET常上调淋巴瘤分期（约40％），PET的检出效能随淋巴瘤的组织类型而变动，尤其对弥漫性大B细胞淋巴瘤和霍奇金病诊断率高。

In recent years, the quantities of PET centers in China increased dramastically, and more than 30 PET centers were established, in which cyclotrons, hotcell and PET scanners were included.

由于PET中心在运行过程中，需要处理大量的放射性问题，因此，很有必要对PET中心运行中涉及的放射性进行系统、全面的监测、分析和讨论，并提出合理的建议，以加强辐射防护措施，保证人员的安全。

Devise a pair of primer to put out the section of pgE which code the dense antigen episode, clone into pET-32a, name the masculine plasmid with pET-32pgE. Transform the BL21 strain with pET-32pgE, choose several single bacterium drops at random and contaminate 2X YT. vibrate at 37癈 over night. Contaminate another tube with the above culture to the final concentration of 2%, continue to culture to OD6oo0.6, add IPTG to the final concentration of Immol/L. inducing 6 hours. Analyse the expression with SDS-PAGE and Western-blot, the result is that the expression has actually happened and the product has immunoreactivity.
