Interstitial pneumonia develops not only as a rheumatoid arthritis (RA) manifestation, but also due to the side effects of drugs for its treatment, leading to the necessity of regular examinations. Krebs von den Lungen-6 (KL-6) is often used to check the activity of interstitial pneumonia in RA patients. However, this marker is also produced by some malignant tumors, and a high level of serum KL-6 has been reported in cancer patients. We describe herein 2 cases of RA with the complication of a malignant tumor not involving the lung, although there is no lesion in the lung regardless of the high level of serum KL-6.

依托独特的稻田臭氧FACE(Free air gas concentration enrichment,开放式空气中气体浓度增高)系统平台,以武运粳21为供试水稻品种,设置正常浓度O3(即大气背景浓度)和高浓度O3(实际比大气背景浓度增高25%左右),定量研究地表O3浓度升高对粳稻抗倒能力的影响。结果表明:高浓度O3对水稻抽穗期和抽穗后20 d基部节间的抗折力和弯曲力矩没有显著影响,但使成熟期基部节间的抗折力和弯曲力距有所降低。因此,臭氧胁迫下水稻抽穗期、抽穗后20 d和成熟期基部节间的倒伏指数均无显著变化。进一步研究结果表明,臭氧胁迫下水稻成熟期基部节间单位长度干重和非结构性碳水化合物含量降低引起基部节间充实不良是造成抗折力显著下降的主要原因,而基部节间弯曲力矩下降是稻穗和节间的长度和质量下降共同作用的结果。以上结果表明,未来高浓度臭氧环境条件下粳型水稻的倒伏风险可能不会增加。

随着金属导线线宽的不断缩小,在90nm 技术以下,刻蚀残留物的存在会在应力迁移测试中形成高通孔电阻和空洞成核现象。物理氩离子预清洗是一种去除残留物的有效方法。但在应力迁移测试中发现,底部沟槽铜的二次溅射会导致器件的早期失效。反应性预清洗方法由于含有H +、H 类粒子而在减少C uO x 和清洗Si,N ,F,C ,O ,等蚀刻残留物时表现出其优越性。提出了针对传统PV d 工艺的反应性预清洗及PV d 击穿(沉积,刻蚀,沉积)工艺的解决方案。阻挡层击穿工艺减少了通孔电阻,提高了应力迁移性能,并通过薄钽沉积工序防止了铜的扩散从而保护了双嵌入斜面和错位通孔。此外,使电子阻塞和局部加热效应最小化的U 型界面,提高了电子迁移失效的平均时间,一致的、可重复的覆盖膜特性和良好的电参量测试结果已经证实了这种工艺的生产价值。

肺部毛玻璃样结节（ground-glass opacity，GGO）在临床工作中经常遇到，将来体检也会发现更多的病例。在肺癌和癌前病变组织等良性和恶性病变中均可发现GGO改变。非典型腺瘤性增生和原位腺癌通常表现为纯GGOs；而腺癌进展后可表现为在GGO病变内有更多的实体成分。GGOs的发展演变过程已逐渐明确。约20％的纯GGOs和40％的部分实体GGOs会逐步增大或者其实体成分不断增多，而其他病变可能多年无变化。是否所有肺部GGO病变都应手术切除抑或无变化的病变无需手术切除？对此，至今仍未明确。数据显示，纯GGOs的体积倍增时间大约在600～900d，而部分实体GGOs体积倍增时间大约在300～450d，因此，要区分GGO病变是否在变化，3年随诊观察期较为合适。未来专门针对有无增长GGOs的基因差异研究，将有助于建立一套合理的处理策略。

Our purpose in this study was to develop an automated method for measuring three-dimensional (3d) cerebral cortical thicknesses in patients with Alzheimer’s disease (Ad) using magnetic resonance (MR) images. Our proposed method consists of mainly three steps. First, a brain parenchymal region was segmented based on brain model matching. Second, a 3d fuzzy membership map for a cerebral cortical region was created by applying a fuzzy c-means (FCM) clustering algorithm to T1-weighted MR images. Third, cerebral cortical thickness was three- dimensionally measured on each cortical surface voxel by using a localized gradient vector trajectory in a fuzzy membership map. Spherical models with 3 mm artificial cortical regions, which were produced using three noise levels of 2%, 5%, and 10%, were employed to evaluate the proposed method. We also applied the proposed method to T1-weighted images obtained from 20 cases, i.e., 10 clinically diagnosed Ad cases and 10 clinically normal (CN) subjects. The thicknesses of the 3 mm artificial cortical regions for spherical models with noise levels of 2%, 5%, and 10% were measured by the proposed method as 2.953 ± 0.342, 2.953 ± 0.342 and 2.952 ± 0.343 mm, respectively. Thus the mean thicknesses for the entire cerebral lobar region were 3.1 ± 0.4 mm for Ad patients and 3.3 ± 0.4 mm for CN subjects, respectively (p d method could be feasible for measuring the 3d cerebral cortical thickness on individual cortical surface voxels as an atrophy feature in Ad.
