Introduction: For clinical assessment of neoadjuvant radiochemotherapy of esophageal cancer reliable in-vivo methods are necessary. Therefore, the capabilities of F-18-Fluorodesoxyglucose-PET in comparison to histomorphological grading of tumor regression were studied. Methods: In 33 patients with locally advanced esophageal carcinoma (uT3, uN0-1, cM0) F-18-FDG-PET was performed before and 2 weeks after radiochemotherapy. All tumors were resected by transthoracic en-bloc esophagectomy 3–4 weeks after induction therapy. A subgroup of 11 patients underwent weekly PET scan during neoadjuvant therapy. PET was performed in a dedicated scanner 1.3 h after administration of 370 MBq F-18-FDG. Data analysis based on maximum SUV data derived from individual regions of interest in pre- and posttherapeutic images. PET data were compared to histomorphological grading parameters for tumor regression whithin the resected tissues. Results: The comparison of histopathological tumor regression after neoadjuvant therapy and PET SUV di?erences showed a signi?cant χ2 P -value of 0.006. There was a signi?cant decrease 五笔字型计算机汉字输入技术 of the SUV data from 9.1±3.5 to 4.3±1.9 (P <0.0001). In therapy responders SUV was diminished by 59 % and in non-responders by 34 %. Longitudinal SUV measurement during neoadjuvant therapy showed a strong SUV decrease already after one and two weeks (P =0.021 and 0.003). Conclusion: The recent data of the FDG-PET follow-up after neoadjuvant therapy show that PET is able to predict therapy response. Longitudinal PET data advocate that it may be possible to recognize response also very early during radiochemotherapy.

研究表明装饰用带状织物的染色能够通过紫外线引发的固化作用来实现,无任何污染。与传统染色方法相比,其带状织物的颜色、光泽和染色牢度能满足高标准。染色后带状织物的手感较差,但可以用轧光整理加以改善。颜料被认为是最合适的着色剂,它能被液化涂层体系完全润湿且满足染色必需的基本要求,诸如色牢度。

三叉戟Ⅰ导弹的一个特点是采用可伸缩的头部减阻杆,减阻杆使气流分离动压降低,来减少钝头的阻力。阿波罗土星助推器的经验证明,气流分离可能为某些临界自由-自由弯曲振型提供负气动阻尼。问题的关键是要确定负阻尼达到足以使导弹结构受到破坏的条件。本文对这种气动阻尼作了分析,包括减阻杆不连续挠曲对气劝阻尼的影响,这种挠曲是由于减阻杆受到气动加热而膨胀,使杆结头松动所引起的。脉动压力在减阻杆上能传导最严重的横向气动载荷,因此本文还列出了脉动压力风洞实验数据。

关键词：减阻杆脉动压力分离流挠曲阻尼导数负阻尼极限周期振荡气动阻尼
