| 1 | Effect of preoperative nutrition therapy type and duration on short-time outcomes in gastric cancer patient with gastric outlet obstruction显示文摘Objective:To avoid perioperative complications caused malnutrition,nutrition therapy is necessary in gastric outlet obstruction(GOO)patients.Compared to parenteral nutrition(PN),enteral nutrition(EN)is associated with many advantages.This study aimed to investigate whether preoperative EN has beneficial clinical effects compared to preoperative PN in gastric cancer patients with GOO undergoing surgery.Methods:According to the methods of preoperative nutrition therapy,143 patients were divided into EN group(n=42)and PN group(n=101)between January 2013 and December 2017 at the Chinese People’s Liberation Army General Hospital.Multiple logistic regression models were used to assess the association between the methods of preoperative nutrition therapy and postoperative day of flatus passage.The generalized additive model and twopiecewise linear regression model were used to calculate the inflection point of the preoperative nutritional therapy time on the postoperative day of flatus passage in the PN group.Results:EN shortened the postoperative day of flatus passage in gastric cancer patients with GOO,which is a protective factor,especially in patients who underwent non-radical operations and the postoperative day of flatus passage reduced when the preoperative PN therapy was up to 3 d and a longer PN therapy(>3 d)did not accelerate the postoperative recovery of gastrointestinal functions.Conclusions:Preoperative EN therapy would benefit gastric cancer patients with GOO by accelerating postoperative recovery.For patients with absolute obstruction,no more than 3-day PN therapy is recommended if patients can tolerate general anesthesia and surgery. | Jiyang Li Shaoqing Li Hongqing Xi Peifa Liu Wenquan Liang Yunhe Gao Chuang Wang Bo Wei Lin Chen Yun Tang Zhi Qiao | 2021 | Chinese Journal of Cancer Research2021，33，2： | 4 |
| 2 | Influence of complex topography on global solar radiation in the Yangtze River Basin显示文摘全球太阳的放射(GSR ) 是全球精力的最直接的来源和形式,并且它的数量的计算由于本地地形学和地面的影响是高度复杂的内部防护。数字举起模型(DEM ) 数据作为复杂地面和复合状况的一个代表生产一系列地志的因素(例如斜坡,方面,等等) 。基于 1 个 km 决定 DEM 数据,气象学的观察和 NOAA-AVHRR 遥感数据,为在在长江盆以内的崎岖地面上的 GSR 的计算的一个分布式的模型被开发了。贯穿的模型为崎岖地形学允许天体的太阳的放射的计算并且包括一个分布式的直接太阳的放射模型,一个分布式的弥漫的放射模特儿和分布式的地面反射放射当模特儿。用发达模型, GSR 空间分发和可视化的量的模拟被承担了,与随后关于地区和地面分析的结果。分析建议那 GSR 大小季节地被影响,当影响的度被发现与增加高度在同时发生增加时。而且, GSR 大小关于主导的本地方面展出了清楚的空间变化;与阳光充足的南部的斜坡联系的 GSR 价值比与遮的斜坡联系的那些显著地大。错误分析显示 12.983 MJm 的一个吝啬的绝对错误<啜class=“ a-plus-plus ”> 2 和3.608%的一个吝啬的相对错误,当结果基于一个地点认证过程显示 22.621 MJm 的一个绝对错误时<啜class=“ a-plus-plus ”> 2 和4.626%的一个相对错误。 | WANG Li QIU Xinfa WANG Peifa WANG Xiaoying LIU Aili | 2014 | Journal of Geographical Sciences2014，24，6： | 4 |
| 3 | Duple-EDA and sample density balancing显示文摘In this paper,a new method is proposed to overcome the problem of local optima traps in a class of evolutionary algorithms,called estimation of distribution algorithms(EDAs) ,in real-valued function optimization. The Duple-EDA framework is proposed in which not only the current best solutions but also the search history are modeled,so that long-term feedback can be taken into account. Sample Density Balancing(SDB) is proposed under the framework to alleviate the drift phenomenon in EDA. A selection scheme based on Pareto ranking considering both the fitness and the historical sample density is adopted,which prevents the algorithm from repeatedly sampling in a small region and directs it to explore potentially optimal regions,thus helps it avoid being stuck into local optima. An MBOA(mixed Bayesian optimization algorithm) version of the framework is implemented and tested on several benchmark problems. Experimental results show that the proposed method outperforms a standard niching method in these benchmark problems. | CAI YunPeng XU Hua SUN XiaoMin JIA PeiFa LIU ZeHua | 2009 | Science in China(Series F)2009，52，9： | 2 |
| 4 | Polarity-triggered anti-Kasha system for high-contrast cell imaging and classification显示文摘Kasha’s rule,which states that all exciton emissions occur from the lowest excited state and are independent of excitation energy,makes high-energy excitons difficult to use and severely hinders the widespread applications of organic photoluminescent materials in the real world.For decades,scientists have tried to break this rule to unleash the power of high-energy excitons,but only minimal progress has been achieved,with no rational guiding principles provided,and few applications developed.So far,breaking Kasha’s rule has remained a purely academic concept.In this paper,we introduce a design principle for a purely organic anti-Kasha system and synthesise a series of compounds based on the design rule.As predicted,these compounds all display evident S_(2) emissions in dilute solutions.In addition,we introduce a highly accurate(over 90%)convolutional neural network as an assistant for the classification of cells using anti-Kasha luminogens,thereby providing a new application direction for anti-Kasha systems. | Junyi Gong Peifa Wei Junkai Liu Yuncong Chen Zheng Zhao Weijun Zhao Huilin Xie Chao Ma Jacky W.Y.Lam Kam Sing Wong Ying Li Ben Zhong Tang | 2023 | Aggregate2023，4，2： | 0 |
| 5 | Positive/Negative Phototropism:Controllable Molecular Actuators with Different Bending Behavior显示文摘Herein,a series of molecular actuators based on the crystals of(E)-2-(4-fluorostyryl)benzo[d]oxazole(BOAF4),(E)-2-(2,4-difluorostyryl)benzo[d]oxazole(BOAF24),(E)-2-(4-fluorostyryl)benzo[d]thiazole(BTAF4),and(E)-2-(2,4-difluorostyryl)benzo[d]thiazole(BTAF24)showed unique bending behavior under UV irradiation.The one-dimensional(1D)crystals of BOAF4 and BTAF4 bent toward light,whereas those of BOAF24 and BTAF24 bent away from light.Although the chemical structures of these compounds are similar,the authors found that F···H–C interaction played a key role in the different molecular packing in structures crystals,which led to the positive/negative phototropism of the actuators.Moreover,theoretical calculations were carried out to reveal the mechanical properties of the crystals.Taking advantage of these photomechanical properties,the authors achieved the potential application in pushing objects,as well as enriching and removing pollutants.Hence,the molecular actuators with different bending behavior could be fabricated by introducing different number of F atom,which may open a novel gate for crystal engineering. | Haoran Wang Jiapeng Liu Kaiqi Ye Qiyao Li Jianyu Zhang Hao Xing Peifa Wei Jingbo Sun Francesco Ciucci Jacky WYLam Ran Lu Ben Zhong Tang | 2021 | CCS Chemistry2021，3，4： | 0 |
