AIM： To investigate the clinicopathologic features which predict surgical overall survival in patients with proxima gastric carcinoma involving the esophagus （PGCE）. METHODS： Electronic pathology database established in the Department of Pathology of the Nanjing Drum Tower Hospital was searched for consecutive resection cases of proximal gastric carcinoma over the period from May 2004 through July 2009. Each retrieved pa- thology report was reviewed and the cases with tumors crossing the gastroesophageal junction line were se- lected as PGCE. Each tumor was re-staged, following the guidelines on esophageal adenocarcinoma, accord- ing to the 7th edition of the American Joint Commission on Cancer Staging Manual. All histology slides were studied along with the pathology report for a retrospec- tive analysis of 13 clinicopathologic features, i.e., age, gender, Helicobacter pylori （H. pylon} infection, surgical modality, Siewert type, tumor Bormann＇s type, size, dif- ferentiation, histology type, surgical margin, lympho- vascular and perineural invasion, and pathologic stage in relation to survival after surgical resection. Prognos- tic factors for overall survival were assessed with uni- and multi-variate analyses. RESULTS： Patients＇ mean age was 65 years （range： 47-90 years）. The male： female ratio was 3.3. The 1-, 3- and 5-year overall survival rates were 87%, 61% and 32%, respectively. By univariate analysis, age, male gender, H. pylori, tumor Bormann＇s type, size, histology type, surgical modality, positive surgical margin, lym- phovascular invasion, and pT stage were not predictive for overall survival; in contrast, perineural invasion （P = 0.003）, poor differentiation （P = 0.0003）, 〉 15 to- tal lymph nodes retrieved （P = 0.008）, positive lymph nodes （P = 0.001）, and distant metastasis （P = 0.005） predicted poor post-operative overall survival. Celiac axis nodal metastasis was associated with significantly worse overall survival （P = 0.007）. By multivariate analys

A novel adsorbent was prepared by modifying orange peel with sodium hydroxide and calcium chloride. The morphological and characteristics of the adsorbent were evaluated by infrared spectroscopy （IR）, scanning electron microscopy （SEM） and N2-adsorption techniques. The adsorption behavior of Cu^2＋, Pb^2＋ and Zn^2＋ on modified orange peel （SCOP） was studied by varying parameters like pH, initial concentration of metal ions. Equilibrium was well described by Langmuir equation with the maximum adsorption capacities for Cu^2＋, Pb^2＋ and Zn^2＋ of 70.73, 209.8 and 56.18 mg/g, respectively. Based on the results obtained in batch experiments, breakthrough profiles were examined using a column packed with SCOP for the separation of small concentration of Pb^2＋ from an excess of Zn^2＋ followed by elution tests. Ion exchange with Ca^2＋ neutralizing the carboxyl groups of the pectin was found to be the predominant mechanism.

地图构建是实现无人驾驶的重要前提,针对传统单一地图无法准确实现无人车自主导航的问题,本文中提出一种低成本的室外多图层地图,分轨迹层-静态层-动态层。轨迹层为GNSS拓扑地图,静态层为基于图优化构建的点云-栅格地图,动态层为实时激光点云信息。首先轨迹层的绝对位置信息用于实现无人车的全局路径规划,然后基于动态层实时信息与静态层的点云地图做匹配,完成无人车实时高精度定位,最后对动态层进行障碍物检测,通过将实时障碍物信息同静态层的栅格地图结合,为无人车避障和局部路径规划提供环境信息。在实际环境下对提出的地图进行了评估,验证了该地图的可用性。

To the Editor: The gallbladder polyp detection rate has been increasing due to the growing use of abdominal imaging technology and the incidence of gallbladder polyps, occurring in 5%-10% of the global adult population [1]. Gallbladder polyps can be divided into true polyps and pseudo polyps, and the latter are more common. Pseudo polyps have no malignant potential.

High nitrogen （N） input features China＇s intensive rice production system. To elucidate N and genotype effects on accumulation of macronutrients and micronutrients in grains of japonica rice, and to discuss its significance in rice production, a three-year field experiment involving six japonica rice varieties and seven N treatments were performed. Macronutrients （Ca, Mg, K, and Na） and micronutrients （Cu, Fe, Mn, and Zn） concentrations in brown and milled rice were measured using an atomic absorption spectrophotometer. For macronutrients, no consistently significant effect of N was detected in both brown and milled rice. For micronutrients, N showed significant effect, especially in lowering Zn accumulation in brown and milled rice. In addition, N tended to increase Fe concentration in milled rice. Genotype showed larger effect on distribution of minerals in milled rice than N. The high-yielding variety, Wuyunjing 7, accumulated larger proportion of Mg, K, and Zn in the milled rice as compared with the other five varieties and could be of value for rice breeding programs aiming at high nutritional quality. The results demonstrated differences in response to N between macronutrients and micronutrients, and are of significance for coping with ＇hidden hunger＇ both in humans and crops through agronomical practices.
