1Expanded endoscopic therapy criteria should be cautiously used in intramucosal gastric cancer显示文摘Objective: Accurate estimation of lymph node metastasis(LNM) in intramucosal gastric cancer is essential to select less invasive treatment options and even avoid surgery. The aim of this study was to evaluate combined clinicopathological features to predict the presence of LNM.Methods: A retrospective review of data from 386 intramucosal gastric cancer patients who underwent gastrectomy with extended lymphadenectomy from 2003 to 2010 was conducted. The mutual relation between clinicopathological characteristics and LNM was analyzed.Results: LNM was detected in 40(10.4%) of the 386 patients. Histological type and vascular or lymphatic invasion presence showed a positive correlation with LNM occurrence by univariate analysis. Multivariate analysis revealed that histological type was the only factor associated with LNM. Combined clinicopathologic characteristics would be more predictable for LNM. We found no LNM when we used combined clinicopathological characteristics conforming to Japanese absolute indications for endoscopic therapy. The LNM rate was as high as 8.7% when Japanese expanded criteria were used. Univariate analysis in cancer conformity to expand endoscopic submucosal dissection(ESD) indication also revealed that the undifferential type was the only significant factor for LNM.Conclusions: It was possible to predict intramucosal gastric cancer cases without LNM using combined clinicopathological characteristic analysis. Extended indication for ESD should be cautiously used for intramucosal gastric cancer patients.Hongshan Wang Heng Zhang Cong Wang Yong Fang Xuefei Wang Weidong Chen Fenglin Liu Kuntang Shen Xinyu Qin Zhenbin Shen Yihong Sun 2016Chinese Journal of Cancer Research2016,28,3:8
2Acute toxicity formation potential of benzophenone-type UV filters in chlorination disinfection process显示文摘Benzophenones(BPs) are a class of widely used UV filters, which have been frequently detected within multiple environmental matrices. Disinfection is a necessary process in water treatment processes. The transformation behaviors and toxicity changes of 14 BP-type UV filters during chlorination disinfection treatment were investigated in this study. A new index, the acute toxicity formation potential, was proposed to evaluate the toxicity changes and potential risks of BP-type UV filters during chlorination treatment. It was found that 13 of 14 BP-type UV filters exhibited toxicity decreases in the chlorination disinfection process, more or less, while one showed a toxicity increase. The toxicity changes were dependent on substitution effects, such that 2,4-di-hydroxylated or 3-hydroxylated BPs exhibited significant toxicity decreases after chlorination treatment due to the ready cleavage of the aromatic ring. Importantly, the acute toxicity changes could be duplicated in an ambient water matrix.Qi Liu Zhenbin Chen Dongbin Wei Yuguo Du 2014Journal of Environmental Sciences2014,26,2:5
3Characteristic analysis of phospholipid fatty acids (PLFAs) in typical nutrient polluted lake sediment in Wuhan显示文摘The process of urbanization aggravates the endogenous pollution of urban lake sediment,and polluted sediment may seriously affect the quality of the water in lakes.At present,it is difficult to distinguish the difference between sediment that is heavily polluted by nitrogen(N)and phosphorus(P)when using an analysis based on a physicochemical index classification.The current study applied phospholipid fatty acid(PLFA)technology to further analyze the sediment characteristics from the perspective of microbiology.Surface sediment from five urban lakes that are heavily polluted with N and P in Wuhan were sampled.Statistical approaches were used to analyze the microbial community structure in the sampled sediment,and to determine the correlations between the microorganisms and physicochemical indices.The most severely polluted lake sediment had similar PLFA structures,the highest saturated fatty-acid content,and bacteria as the dominant microorganism.However,there were differences between the microbial biomass of the various sediment samples,which may have been related to the degree of N and P pollution.Analysis of the microbial diversity in the sediment samples indicated that the bacteria were experiencing starvation and nutrient pressure,which may have been due to the dissolved oxygen concentration of the heavily polluted lake sediment.A correlation analysis showed that the endogenous N and P had different effects on the microbes of the polluted sediment.A redundancy analysis(RDA)demonstrated that the N/P ratio had the greatest influence on the PLFA species,accounting for 83%of the cumulative interpretation.To effectively promote the role of sediment microorganisms on circulating elements,it is necessary to regulate the N/P ratio of the sediment to some extent.When the N/P ratio in sediment exceeds 6,N pollution should be prioritized.Xia Zhang Qianru Chen Chuan Wang Hongpei Zhang Yuqing Zhao Liping Zhang Biyun Liu Zhenbin Wu Qiaohong Zhou 2021International Journal of Sediment Research2021,36,2:5
4Study on fish life history traits and variation in the Taiwan Strait and its adjacent waters显示文摘Large portions of the world's fishery resources are overexploited. Life history traits of fish species are important indicators to reveal different life history strategies and to indicate population responses to fishing pressures. For this study, empirical data on fishing grounds located in the coastal area between Fujian Coast and Taiwan Island were collected. These areas have experienced severe overfishing in the past 30 years, leading to changes in the structure and function of the fish communities. Fifty-one commercial fish species in this fishing ground were selected to study the life history traits. Using the life history traits, all the species were grouped into five different life history strategies by principle component analysis. More than 60% of the species were categorized in Group 5 that was similar to r-strategists. Twenty-five commercial species were selected for further analysis of changes in life history variables, and to discuss the population responses to exploitation. Results showed that most of the species appeared to become smaller size, shorter life, earlier maturation and faster growing under long-term exploitation. The exploitation rate of each species was also calculated to further discuss the impacts of fishing pressures to fish populations. Four species were found with the severest changes on life history traits indicating some of the species might be more susceptible to exploitation. This study on fish life history traits and their long-term variations under fishing pressures could provide important scientific implications for fishery management and conservation.HU Wenjia YE Guanqiong LU Zhenbin DU Jianguo CHEN Mingru CHOU Loke Ming YANG Shengyun 2015Acta Oceanologica Sinica2015,34,2:3
5Exergy Analysis of a Novel Chemical Looping Hydrogen Generation System Integrated with SOFC显示文摘In this paper,a novel system integrating chemical-looping hydrogen generation(CLH)system and solid oxide fuel cell(SOFC)has been proposed.This new methane-fuelled energy system was investigated with energy balance and exergy analysis.CLH produces the hydrogen as the fuel of the SOFC,and the Fe O and Fe3O4 are selected as the looping material.Waste heat from the SOFC is absorbed by the CLH and converted to chemical energy through the reduction reaction of CLH.Owing to the cascade utilization of the fuel between the CLH and SOFC,the net efficiency of this novel system can achieve 62.8%considering CO_(2)separation,more than 10 percentage points higher than a methane reforming fuelled SOFC system.Meanwhile,by using the CLH to produce the hydrogen,the CO_(2)can be recovered without an energy penalty.Through the analysis of the graphical exergy,the cascade utilization of waste heat and the high-efficiency hydrogen production is the main reason of high performance.This novel system also has the advantage of CO_(2)capture without energy penalty,so this combined system is an advantaged method to accomplish the efficient utilization of methane.ZHANG Xiaosong CHEN Zhewen CHEN Zhenbin LI Jinsong 2021Journal of Thermal Science2021,30,1:2
6Synthesis of dimethyl adipate from cyclopentanone and dimethyl carbonate over solid base catalysts显示文摘A facile route for the synthesis of dimethyl adipate (DAP) from cyclopentanone and dimethyl carbonate (DMC) in the presence of solid base catalysts has been developed.It was found that the intermediate carbomethoxycyclopentanone (CMCP) was produced from cyclopentanone with DMC in the first step,and then CMCP was further converted to DAP by reacting with a methoxide group.The role of the basic catalysts can be mainly ascribed to the activation of cyclopentanone via the abstraction of a proton in the α-position by base sites,and solid bases with moderate strength,such as MgO,favor the formation of DAP.WU DuDu CHEN Zhi JIA ZhenBin SHUAI Li 2012Science China Chemistry2012,55,3:2

17Construction of hybrid constructed wetlands for phosphorus chemical industry tailwater treatment in the middle Yangtze river basin:Responses of plant growth and root-associated microbial communities显示文摘Constructed wetlands are commonly utilized to treat industrial wastewater due to their effectiveness,affordability,and environmental benefits.Many phosphorus chemical enterprises in the middle Yangtze River basin are facing high pollution load challenges and efforts are needed to improve removal efficiency of pollutants.This work was the first to use constructed wetlands for phosphorus chemical industry tailwater(PCITW)treatment.The new hybrid constructed wetlands(CWs)proposed were the aeration horizontal subsurface flow constructed wetland(AHSCW)and the integrated vertical flow constructed wetland(IVCW),which were constructed on a pilot scale.Here,the effectiveness of pollutant removal along hybrid CWs,wetland plant growth,and rootassociated microbial community responses to the PCITW were investigated.The results showed that there was spatial variation in removal of carbon,nitrogen,and phosphorus in the hybrid CWs,and that the AHSCW and the IVCW played synergistic roles in the removal of pollutants.Compared with influent,the toxic effect of effluent to embryos of a rare minnow(Gobiocypris rarus)was alleviated.Exposure to the effluent resulted in no malformation or death for embryos.Plants and microorganisms in the wetland system of the phosphate chemical tailwater were then compared with the control system of municipal tailwater.Plants in the former system had lower root density,and higher average root diameter,root shoot ratio,specific root length,and specific surface area.Plant roots also had decreased NH_(4)^(+)uptake ability but increased Ca^(2+)uptake to adapt to the high load and complex pollution stress.Unlike the control system,stochastic mechanisms had a more important role than deterministic processes in shaping the microbial community assembly associated with the PCITW.Meanwhile,analysis of microbial network-level topological characteristics demonstrated substantial reduction in network interactions complexity and microbiome stability in the treatment system.Findings from this study suggest wetlands will be helpful for efficient purification of phosphorus chemical industry wastewater in the Yangtze River basin.Qianzheng Li Yao Guo Junqi Yu Lu Yao Shun Liu Yahua Li Disong Chen Fei Peng Dong Xu Zhenbin Wu Qiaohong Zhou 2023Water Biology and Security2023,2,3:1
