AIM to assess nutritional recovery,particularly regarding feeding jejunostomy tube(Fjt)utilization,following upper gastrointestinal resection for malignancy. MEtHODS A retrospective review was performed of a prospectively-maintained database of adult patients who underwent esophagectomy or gastrectomy(subtotal or total)for cancer with curative intent,from january 2001 to june 2014. Patient demographics,the approach to esophagectomy,the extent of gastrectomy,Fjt placement and utilization at discharge,administration of parenteral nutrition(PN),and complications were evaluated. All patients were followed for at least ninety days or until *** the 287 patients underwent upper GI resection,comprised of 182 esophagectomy(n=107 transhiatal,58.7%; n=56 Ivor-Lewis,30.7%)and 105 gastrectomy [n=63 subtotal(SG),60.0%; n=42 total(tG),40.0%]. 181 of 182 esophagectomy patients underwent Fjt,compared with 47 of 105 gastrectomy patients(99.5% vs 44.8%,P t had undergone tG(n=39,92.9% vs n=8 SG,12.9%,P th of stay was similar between esophagectomy and gastrectomy groups(14.7 d vs 17.1 d,P=0.076). Upon discharge,87 esophagectomy patients(48.1%)were taking enteral feeds,with 53(29.3%)fully and 34(18.8%)partially dependent. Meanwhile,20 of 39 tG patients(51.3%)were either fully(n=3,7.7%)or partially(n=17,43.6%)dependent on tube feeds,compared with 5 of 8 SG patients(10.6%),all of whom were partially dependent. Gastrectomy patients were significantly less likely to be fully dependent on tube feeds at discharge compared to esophagectomy patients(6.4% vs 29.3%,P=0.0006). PN was administered despite Fjt placement more often following gastrectomy than esophagectomy(n=11,23.4% vs n=7,3.9%,P=0.0001). Fjt-specific complications requiring reoperation within 30 d of resection occurred more commonly in the gastrectomy group(n=6),all after tG,compared to 1 esophagectomy patient(12.8% vs 0.6%,P=0.0003). Six of 7 patients(85.7%)who experienced tube-re

Acta Metallurgica Sinica(English Letters) 2008年第5期21卷 369-379页

By the sessile drop technique, the wettability of Cu/W systems with the additions of Ni and Cr has been studied under vacuum atmosphere. Effects of Ni and Cr contents and wetting temperatures on the wettability and the wetting mechanisms of copper on W substrate have been investigated in detail. the results show that the wetting angles of Cu on the W substrate are decreased with an increase in the content of Ni or Cr, and also decrease with raising the wetting temperatures. SEM, EPMA, and X-ray diffraction have been used to analyze the interracial characteristics of the CuNi/W and CuCr/W systems. the results reveal that there is a transition layer about 2- 3μm in the interface of Cu-4.0 wt pct Ni/W, in which the interrnetallic phase Ni4W is precipitated. As to CuCr/W system, no reaction occurs at the interface. the two factors are that the contents of Cr and Ni and the infiltration temperature must be chosen appropriately in order to control the interfacial dissolution and reaction when the Cu- W alloys are prepared by the infiltration method.

在地史上的中生代,长颈恐龙的肺部所产生的巨大浮力,足以使长颈恐龙浮于水面而游动,但是为什么它的身体竟有5米之多的部位始终沉没于水中?这个离奇的不解之谜,引起了各国古生物学者的巨大兴趣。学者D.G.德庇在挖掘长颈恐龙化石时,往往在其胃部发现许多被食而未消化的小动物化石及许多石块,终于揭开了这个不解之谜。原来,长颈恐龙与鳄鱼一样,会把许多石块食进胃中,以增加体重来使身体沉没于水中,将鼻与眼伸出水面,来捕获猎物。此外,学者j.A.比松还研究了长颈恐龙的四只脚,根据其脚是前端呈尖状的翼型,断定长颈恐龙不是依靠脚蹼来游动的,它如同海豹、企鹅一样,借助于上

Aim Cluster analysis was conducted on data from 5,169 United States （U.S.） Arizona children, age＇s 5-59-months with the goal of delineating patterns of caries in the primary dentition of pre-school children without a priori pattern definitions. Methodology Cluster analyses were conducted using all data for children ages 0-4 years in aggregate： 1） for all subjects, and 2） for subjects without crowned restored teeth. Each of these two sets of analyses consisted of 8 differently specified cluster analyses as a validation procedure. Results the caries patterns identified from the clustering analysis are： 1） smooth surfaces （other than the maxillary incisor）, 2） maxillary incisor, 3） occlusal surfaces of first molars, and 4） pit and fissure surfaces of second molars. Conclusion the cluster analysis findings were consistent with results produced by multidimensional scaling. these cross-validated patterns may represent resulting disease conditions from different risks or the timing of various risk factor exposures. As such, the patterns may be useful case definitions for caries risk factor investigations in children under 60 months of age.

目的:探讨CtA(Ct血管造影)对指导游离股前外侧肌皮瓣制备的辅助价值及该皮瓣在舌癌术后缺损修复中的临床效果。方法:对17例明确诊断为舌鳞形细胞癌的患者,术前采用CtA辅助定位旋股外侧动脉降支的穿支血管,选取以该穿支血管为蒂的股前外侧肌皮瓣游离移植修复舌癌术后软组织缺损。结果:所有患者术前CtA辅助定位穿支血管的皮瓣制备在术中按计划均获成功,游离移植肌皮瓣全部存活。术后随访6～36个月,患者舌体形态、功能恢复良好,无明显吞咽及言语功能障碍,局部未见肿瘤复发,供瓣肢无功能障碍。其中1例(t_4N_2M_0)于术后12个月合并肝、肺转移后死亡。结论:CtA辅助定位旋股外侧动脉穿支血管的方法可靠、实用,游离股前外侧肌皮瓣是修复舌癌术后软组织缺损较为理想的选择。
