| 1 | Influences of 1-methylcyclopropene-containing papers on the metabolisms of membrane lipids in Anxi persimmons during storage显示文摘Objectives:The aim of this work was to analyse the effects of 1-methylcyclopropene(1-MCP)treatment on the metabolisms of membrane lipids in postharvest Anxi persimmons during storage.Materials and methods:Anxi persimmon(Diospyros kaki L.f.cv.Anxi)fruits were treated by paper containing 1-MCP with a concentration of 1.35μl/l.The cellular membrane permeability was analysed by the electric conductivity meter.The activities of lipoxygenase(LOX),phospholipase(PLD)and lipase were determined by spectrophotometry.The component and relative amounts of membrane fatty acids were determined using gas chromatograph(GC).Results:The 1-MCP-treated Anxi persimmons manifested a lower electrolyte leakage rate,lower LOX,PLD and lipase activities,higher levels of unsaturated fatty acids(USFAs),higher ratio of USFAs to saturated fatty acids(SFAs)(U/S),higher index of USFAs(IUFA),but lower levels of SFAs.Conclusions:The degradation and the metabolisms of membrane lipids could be suppressed by 1-MCP treatment,which might be accountable for the delaying softening of postharvest Anxi persimmons during storage. | Hui Wang Guo Chen Lili Shi Hetong Lin Yihui Chen Yifen Lin Zhongqi Fan | 2020 | Food Quality and Safety2020，4，3： | 2 |

| 3 | Coordinated Exploration Model and its Application to Coal and Coal-associated Deposits in Coal Basins of China显示文摘China is a top world producer of coal resources with numerous coal-rich basins country-wide that also contain coalbed methane(CBM),an unconventional natural gas resource.Recent exploration of coal and CBM resources has also led to the discovery of rare,precious,and scattered metal minerals,including sandstone-type U and Ga–Ge–Li.High-grade and industrial-value deposits have been discovered in the Ordos,Junggar,and other basins across China during exploration for coal resources.Application of coordinated exploration theories and techniques in multiple energy and coal-associated ore deposits,such as coal and unconventional natural gas in coal,achieves efficient and practical exploration of natural resources.Based on the systematic study of accumulation and occurrence of coal and coal-associated mineral resources in coal basins,the basic idea of coordinated exploration for coal and coal-associated deposits is proposed,and multi-targets and multi-methods based on a coordinated exploration model of coal-associated deposits is developed.Coordinated exploration expands the main exploration objective from coal seams to coal-associated series,extending the exploration target from targeting coal only to coal-associated deposits.Entrance times for exploration are decreased to realize coordinated exploration for coal,unconventional natural gas and syngenetic/associated mineral resources in coal by implementing a’one-time approach’―one time in and out of a coal seam to minimize disturbance and time needed for extraction.According to the differences of geological background in China’s coal basins,four coordinated exploration model types,including co-exploration of coal and coal-associated unconventional natural gas,coal and solid minerals,coal and metal minerals,and coal with water resources are established.Other models discussed include a multi-target coordinated exploration model for the combination of coal,coal-associated gas,solid minerals,and metal minerals accordingly.The exploration techniques of coal and coal-associated resources include regional geological investigation and research and synthetic application of other techniques including seismic surveys,drilling,logging,and geochemical exploration.Particularly,applying the’multi-purpose drill hole’or reworking coalfield drill holes into parameter wells,adding sample testing and logging wells,determining gas-bearing layers by logging and gas content measurement,jointly measuring multiple logging parameters,sampling,and testing of coal-strata help in the exploration and evaluation of coal resources,coal-associated unconventional natural gas resources,and coal-associated element minerals.Accordingly,a system of integrated Space–Air–Ground exploration techniques for coordinated exploration of coal and coal-associated minerals is established.This includes high-resolution,hyperspectral remote-sensing technique,high-precision geophysical exploration and fast,precise drilling,testing of experimental samples,as well as coordinated exploration and determination methods of multi-target factors,multi-exploration means,multi-parameter configuration and optimization,big data fusions and interpretation techniques.In recent years,the application of this integrated system has brought significant breakthroughs in coal exploration in Inner Mongolia,Xinjiang and other provinces,discovering several large,ten-billionton coalfields,such as the Eastern Junggar and Tuha basins,and also in exploration and development of CBM from lowrank coals in Fukang,Xinjiang,discovery the Daying U Deposit in Inner Mongolia,the Junggar Ultralarge Ga Deposit,Lincang,Yunnan,and the Wulantuga,Inner Mongolia,Ge-bearing coal deposits,and the Pingshuo Ultralarge Li–Ge Deposit. | WANG Tong SUN Jie LIN Zhongyue FANG Huiming WANG Yue LIU Yifen | 2021 | Acta Geologica Sinica(English Edition)2021，95，4： | 1 |
| 4 | Prediction of effective percutaneous transhepatic biliary drainage in patients with hepatocellular carcinoma: A multi-central retrospective study显示文摘Background and aim:Percutaneous transhepatic biliary drainage(PTBD)does not always lead to a reduction in serum total bilirubin(TBil)level in patients with hepatocellular carcinoma and obstructive jaundice.We aimed to develop a model for pre-PTBD prediction of post-procedural TBil decrease in these patients.Materials and methods:Retrospective database searches were conducted at four teaching hospitals(reference period:January 2010 to December 2018),and baseline characteristics of eligible patients were extracted.Any decrease in TBil after PTBD and the lowest level of TBil post-PTBD<5 mg/dL,3 mg/dL,and 2 mg/dL were each taken as the standard of effectiveness for computation of its own predictive nomogram.For data dimension decrease and feature selection,the least absolute shrinkage and selection operator(LASSO)regression model was used.A multivariable logistic regression analysis was used to develop nomograms.Each nomogram's performance was internally evaluated for its calibration,discriminative ability,and clinical usefulness.Results:Included in the study were 138 patients.The model for end-stage liver disease(MELD)score,platelet count,and portal vein thrombosis(PVT)were predictors in the nomogram for any decrease in TBil;international normalized ratio(INR),MELD score,platelet count,and PVT were predictors for a decrease to<5 mg/dL;MELD score,cholinesterase level(CHE),platelet count,and PVT were predictors for a decrease to<3 mg/dL;and MELD score,CHE,platelet count,and pre-albumin level were predictors for a decrease to<2 mg/dL.The clinical value of the nomograms was proven by decision curve analysis.Conclusions:These models may help inform clinical decision making for performing PTBD procedures. | Haofan Wang Yitao Mao Chunning Zhang Xiaojun Hu Bin Chen Luwen Mu Shuyi Wang Yifen Lin Zhanwang Xiang Mingsheng Huang | 2022 | Liver Research2022，6，4： | 1 |
| 5 | Game-theoretical explorations of the mesoscale flow structure and regime transitions in bubble columns显示文摘Understanding the mesoscale structure and regime transition in bubble columns is of great significance for reactor design and scaleup.Based on the energy-minimization multiscale(EMMS)model,a noncooperative game model with constraints is proposed to investigate the structural properties of gas-liquid systems in which small and large bubbles are chosen as players and the energy consumption form the objective function.The conservation equations of the system can be regarded as the constraints of the game.For the formulated noncooperative game model,the concept of the generalized Nash equilibrium(GNE)is used to characterize the solution.An algorithm is developed to numerically compute the GNE and some important structural parameters in the system.The numerical results show the existence of the GNE for all values of the superficial gas velocity Ug.As Ug varies,the trends in the state variables can be observed and the critical point of Ug identified.The overall trend of the flow regime transition agrees with the original EMMS model and experimental results,although the GNE calculation also reveals different single-bubble dominant mechanisms with increasing Ug. | Shuo Yuan Yifen Mu Xiaoping Guan Zhixin Liu Jianhua Chen Ning Yang Lin Zhang | 2020 | Particuology2020，18，1： | 1 |

| 8 | Investigation of nanostructure of konjac-based water absorbents with atomic force microscopy显示文摘Atomic force microscopy technology is gradually spreading to almost all aspects,including food science and technology,since it was first invented in 1986.In this study,this powerful instrument was applied to image nanostructures of three water absorbents-original konjac powder,konjac powder grafted with acrylic acid using^(60)Coγ-irradiation and regenerated grafted powder.Water absorption capacities and the rates of the three absorbents were also determined in this work.Original konjac powder could only absorb 60 times(w/w)of water,while 270 times for the grafted absorbent and 360 times for the regenerated absorbent.The initial water absorption rates in both tap and distilled water were high,but the rate decreased steeply as time elapsed.After 20 min,the absorbent was close to saturated status.These physical properties were in accordance with the nanostructures of these three water absorbents. | Shengrong GENG Ruotai LIN Mingli CHEN Shaoyang LIU Yifen WANG | 2009 | Frontiers of Chemical Science and Engineering2009，3，4： | 0 |
| 9 | Self-oxygenated co-assembled biomimetic nanoplatform for enhanced photodynamic therapy in hypoxic tumor显示文摘Photodynamic therapy(PDT)has shown great application potential in cancer treatment and the important manifestation of PDT in the inhibition of tumors is the activation of immunogenic cell death(ICD)effects.However,the strategy is limited in the innate hypoxic tumor microenvironment.There are two key elements for the realization of enhanced PDT:specific cellular uptake and release of the photosensitizer in the tumor,and a sufficient amount of oxygen to ensure photodynamic efficiency.Herein,self-oxygenated biomimetic nanoparticles(CS@M NPs)co-assembled by photosensitizer prodrug(Ce6-S-S-LA)and squalene(SQ)were engineered.In the treatment of triple negative breast cancer(TNBC),the oxygen carried by SQ can be converted to reactive oxygen species(ROS).Meanwhile,glutathione(GSH)consumption during transformation from Ce6-S-S-LA to chlorin e6(Ce6)avoided the depletion of ROS.The co-assembled(CS NPs)were encapsulated by homologous tumor cell membrane to improve the tumor targeting.The results showed that the ICD effect of CS@M NPs was confirmed by the significant release of calreticulin(CRT)and high mobility group protein B1(HMGB1),and it significantly activated the immune system by inhibiting the hypoxia inducible factor-1alpha(HIF-1α)-CD39-CD73-adenosine a2a receptor(A2AR)pathway,which not only promoted the maturation of dendritic cells(DC)and the presentation of tumor specific antigens,but also induced effective immune infiltration of tumors.Overall,the integrated nanoplatform implements the concept of multiple advantages of tumor targeting,reactive drug release,and synergistic photodynamic therapy-immunotherapy,which can achieve nearly 90%tumor suppression rate in orthotopic TNBC models. | Bingchen Zhang Ling Lin Jizong Mao Weisheng Mo Zibo Li Shengtao Wang Yan Tang Chunhui Cui Yifen Wu Zhiqiang Yu | 2023 | Chinese Chemical Letters2023，34，10： | 0 |
