| 1 | Proteomic study provides new clues for complications of hemodialysis caused by dialysis membrane显示文摘The complications of hemodialysis accompanied the hemodialysis and threaten the patients’life.Besides the loss of nutrient substance,such as amino acid and vitamin,we found new clues that the adsorbed proteins on common-used polysulfone-based dialysis membrane might be the reason according to the qualitative proteomic study by ionic liquid assisted sample preparation method.Our results indicated that the adsorbed proteins on the membrane were related with complement activation,blood coagulation,and leukocyte-related biological process.The quantitative proteome further demonstrated some significant changes of signal proteins in the post-dialysis plasma after the hemodialysis,such as beta-2-microglobulin and platelet factor-4,which would further verify these new clues. | Kaiguang Yang Jianhui Liu Jingdi Sun Yuan Zhou Qun Zhao Senwu Li Lukuan Liu Lihua Zhang Jiuyang Zhao Yukui Zhang | 2017 | Science Bulletin2017，62，18： | 2 |
| 2 | Dynamic optimization oriented modeling and nonlinear model predictive control of the wet limestone FGD system显示文摘Nonlinear model predictive control(NMPC)scheme is an effective method of multi-objective optimization control in complex industrial systems.In this paper,a NMPC scheme for the wet limestone flue gas desulphurization(WFGD)system is proposed which provides a more flexible framework of optimal control and decision-making compared with PID scheme.At first,a mathematical model of the FGD process is deduced which is suitable for NMPC structure.To equipoise the model’s accuracy and conciseness,the wet limestone FGD system is separated into several modules.Based on the conservation laws,a model with reasonable simplification is developed to describe dynamics of different modules for the purpose of controller design.Then,by addressing economic objectives directly into the NMPC scheme,the NMPC controller can minimize economic cost and track the set-point simultaneously.The accuracy of model is validated by the field data of a 1000 MW thermal power plant in Henan Province,China.The simulation results show that the NMPC strategy improves the economic performance and ensures the emission requirement at the same time.In the meantime,the control scheme satisfies the multiobjective control requirements under complex operation conditions(e.g.,boiler load fluctuation and set point variation).The mathematical model and NMPC structure provides the basic work for the future development of advanced optimized control algorithms in the wet limestone FGD systems. | Lukuan Yang Wenqi Zhong Li Sun Xi Chen Yingjuan Shao | 2020 | Chinese Journal of Chemical Engineering2020，28，3： | 2 |

| 4 | Multiobjective economic model predictive control using utopia-tracking for the wet flue gas desulphurization system显示文摘Efficient control of the desulphurization system is challenging in maximizing the economic objective while reducing the SO_(2) emission concentration. The conventional optimization method is generally based on a hierarchical structure in which the upper optimization layer calculates the steady-state results and the lower control layer is responsible to drive the process to the target point. However, the conventional hierarchical structure does not take the economic performance of the dynamic tracking process into account. To this end, multi-objective economic model predictive control(MOEMPC) is introduced in this paper, which unifies the optimization and control layers in a single stage. The objective functions are formulated in terms of a dynamic horizon and to balance the stability and economic performance. In the MOEMPC scheme, economic performance and SO_(2) emission performance are guaranteed by tracking a set of utopia points during dynamic transitions. The terminal penalty function and stabilizing constraint conditions are designed to ensure the stability of the system. Finally, an optimized control method for the stable operation of the complex desulfurization system has been established. Simulation results demonstrate that MOEMPC is superior over another control strategy in terms of economic performance and emission reduction, especially when the desulphurization system suffers from frequent flue gas disturbances. | Shan Liu Wenqi Zhong Xi Chen Li Sun Lukuan Yang | 2023 | Chinese Journal of Chemical Engineering2023，54，2： | 0 |
| 5 | Soil properties drive the bacterial community to cadmium contamination in the rhizosphere of two contrasting wheat(Triticum aestivum L.)genotypes显示文摘Cadmium(Cd)bioavailability in the rhizosphere makes an important difference in grain Cd accumulation in wheat.Here,pot experiments combined with 16S rRNA gene sequencing were conducted to compare the Cd bioavailability and bacterial community in the rhizosphere of two wheat(Triticum aestivum L.)genotypes,a low-Cd-accumulating genotype in grains(LT)and a high-Cd-accumulating genotype in grains(HT),grown on four different soils with Cd contamination.Results showed that there was non-significant difference in total Cd concentration among four soils.However,except for black soil,DTPA-Cd concentrations in HT rhizospheres were higher than those of LT in fluvisol,paddy soil and purple soil.Results of 16S rRNA gene sequencing showed that soil type(52.7%)was the strongest determinant of root-associated community,while there were still some differences in rhizosphere bacterial community composition between twowheat genotypes.Taxa specifically colonized in HT rhizosphere(Acidobacteria,Gemmatimonadetes,Bacteroidetes and Deltaproteobacteria)could participate inmetal activation,whereas LT rhizosphere was highly enriched by plant growth-promoting taxa.In addition,PICRUSt2 analysis also predicted high relative abundances of imputed functional profiles related to membrane transport and amino acid metabolism in HT rhizosphere.These results revealed that the rhizosphere bacterial community may be an important factor regulating Cd uptake and accumulation in wheat and indicated that the high Cd-accumulating cultivar might improve Cd bioavailability in the rhizosphere by recruiting taxa related to Cd activation,thus promoting Cd uptake and accumulation. | Min Lu Lukuan Huang Qiong Wang Xuerui Cao Qiang Lin Zhenli He Ying Feng Xiaoe Yang | 2023 | Journal of Environmental Sciences2023，，6： | 0 |
| 6 | Cell-imprinted polydimethylsiloxane for the selective cell adhesion显示文摘Cell adhesion is the basis for some cell isolation methods, and is influenced by both of the biochemical and topographic characteristics of the substrates. Herein, based on cell imprinting and click chemistry,we have developed a cell-imprinted polydimethylsiloxane(PDMS) with aptamer functionalization(APTCIS). The atom force microscopic analysis results showed that the hierarchical structure matching well with the target cells is successfully introduced on the surface of the APT-CIS. By using the synergistic effects of hierarchical structure and aptamer affinity, the APT-CIS was successfully used for the selective cell adhesion, and 93.9% ± 0.8% of the captured cells could then be released. Thus, the APT-CIS holds promise in selective cell isolation and sorting fields. | Lukuan Liu Kaiguang Yang Zhongpeng Dai Zhen Liang Lihua Zhang Xiaojun Peng Yukui Zhang | 2019 | Chinese Chemical Letters2019，30，3： | 0 |
