AIM To investigate the effect of gastroenteric reconstruction on the nutritional status of patients with gastric cancer after total gastrectomy. METHODS From 1989 1994, nutritional status was studied in 24 patients, including 12 patients with the gastric reservoir and pyloric sphincter reconstruction (GRPS), 7 with Braun′s esophago jejunostomy (EJ) and 5 with Lawrance′s Roux en Y reconstruction (RY). The ability of these patients to ingest and absorb the amount of nutrients was examined and compared, and metabolic balance test was performed to compare the efficiency of those patients to accumulate and use the absorbed nutrients. RESULTS In the controlled hospital situation, the amount of food ingested by all the patients was greater than that required for maintenance of ideal body weight. In direct contrast, food intake in most patients with EJ or RY reconstruction significantly decreased when the patients returned home and that in EJ patients it was the lowest. The overgrowth of anaerobic bacteria was found in the jejunum in the patients with EJ and RY, due mainly to food stasis in the duodenum or in the Roux limb, caused by the operative procedure itself. In patients with GRPS, because of restoring of the alimentary continuity according to the normal digestive physiologic characters, all the nutritional parameters could fall in the normal range. CONCLUSION The most common mechanism responsible for postoperative malnutrition was inadequate food intake. Having solved the problem of alkaline reflux esophagitis, it is imperative to preserve the duodenal food passage to reduce malabsorption and other complications after total gastrectomy.

厚街体育馆钢屋盖采用大跨度椭圆抛物面弦支穹顶结构,支座间净跨110m×80m,上部单层网壳矢高9.4 m.分别以此结构与相应的单层网壳为分析对象,采用改进的随机缺陷模态法,对两类结构的缺陷敏感区域进行对比研究.在此基础上,进一步探讨局部拓扑形式改变及活载半跨分布对弦支穹顶结构缺陷敏感区域的影响.研究表明:弦支穹顶结构的缺陷敏感区域位于上部单层网壳;弦支穹顶与相应单层网壳的缺陷敏感区域有较大差异,下部索杆体系的引入明显改善了上部单层网壳的缺陷敏感性;局部拓扑形式的改变,可有效降低结构的缺陷敏感程度;活载的半跨分布对传统拓扑形式弦支穹顶结构缺陷敏感区域的影响并不大,但对于该结构上部单层网壳中心区域的影响较为显著.

以陕西省杨凌示范区为研究区域,利用遥感生态指数模型(RSEI)结果表征区域生态环境质量状况,以地形、气候、土壤、植被、人类活动等因子,以及模型自身的结构因子作为分析因子,应用地理探测器方法,从单因子分析及多因子交互作用分析2个层面,定量探测诸因子对RSEI模型结果的影响程度,进而揭示研究区生态环境质量状况主要的影响因素,以及因子间交互作用的影响方式。结果表明,在单因子分析层面,归一化水汽指数(NDMI)对杨凌示范区RSEI空间分异特征的解释力最强,是研究区生态环境质量状况最重要的影响因素;在多因子交互分析层面:研究区RSEI空间分异特征是多种因子共同作用的结果,所有因子在交互作用下均有协同增强的作用;NDMI与绿度分量协同作用的影响最为显著,解释力高达91.9%;归一化差值不透水面指数(NDISI)与土地利用类型交互作用的解释力,较二者分别作为独立变量时的解释力有极大的提升,非线性增强溢出C值高达0.258。依据以上研究结果,杨凌示范区在未来生态环境规划、管理中,NDMI可作为重要的指标和因子用于指示区域环境质量状况。另外也应重点关注多因素之间的交互作用对区域生态环境质量的影响,特别是城市建设与土地利用方式交互的影响。

In order to improve the toughness and wear resistance of high-boron medium-carbon alloy （HBMCA）, a novel wear-resistant HBMCA comprising granular borocarbide was obtained by titanium, magnesium, and rare earth modifications. These modifications gave rise to greatly refined as-cast eutectic borocarbide structures and a less interconnected continuous borocarbide network. Heat treatment mostly produced broken and spheriodized borocarbides that tended to exist as isolated particles in modified HBMCA. The heat treated modified HBMCA exhibited enhanced hardness than pristine and impact toughness was improved significantly to 12.5 J/cm^2. In addition, it displayed 2.39 and 1.7 times greater wear resistance than high-speed steel （HSS） and high nickel-chromium alloy steel （Cr25） at high temperature （500℃）, respectively. Here, the modification mechanisms involving Re2O3, TiN, and MgO/ MgS heterogeneous nuclei were discussed.
