2Risk factors for intracranial hemorrhage and mortality in adult patients with severe respiratory failure managed using veno-venous extracorporeal membrane oxygenation显示文摘Background: Intracerebral hemorrhage (ICH) is one of the most severe complications during veno-venous extracorporeal membrane oxygenation (VV-ECMO). This study aimed to determine the risk factors for ICH and mortality in such patients.Methods: We analyzed the clinical data of 77 patients who received VV-ECMO due to severe respiratory failure from July 2013 to May 2019 at China-Japan Friendship Hospital. Demographical data, laboratory indices, imaging characteristics, and other clinical information were collected. Multivariable logistic regression analyses were performed to identify risk factors for ICH and mortality.Results: Of 77 patients, 11 (14.3%) suffered from ICH, and 36 (46.8%) survived. The survival rate was significantly lower (18.2% [2/11]vs. 51.5% [34/66],P = 0.040) in patients with ICH than in those without ICH. Multivariable analysis revealed that factors independently associated with ICH were diabetes mellitus (adjusted odds ratio [aOR]: 12.848, 95% confidence interval [CI]: 1.129-146.188,P = 0.040) and minimum fibrinogen during ECMO (aOR: 2.557, 95% CI: 1.244-5.252,P = 0.011). Multivariable analysis showed that factors independently associated with mortality were acute hepatic failure during ECMO (aOR: 9.205, 95% CI: 1.375-61.604,P = 0.022), CO2 retention before ECMO (aOR: 7.602, 95% CI: 1.514-38.188,P = 0.014), and minimum platelet concentration during ECMO (aOR: 0.130, 95% CI: 0.029-0.577,P = 0.007).Conclusions: Diabetes mellitus and minimum fibrinogen concentration during ECMO are risk factors for ICH in patients with severe respiratory failure managed using VV-ECMO. This indicated that anticoagulants use and nervous system monitoring should be performed more carefully in patients with diabetes when treated with VV-ECMO due to severe respiratory failure.Xiaojing Wu Min Li Ying Cai Tianshu Zhai Yi Zhang Qingyuan Zhan Sichao Gu 2022Chinese Medical Journal2022,,1:1
3Conversion of lignin oil and hemicellulose derivative into high-density jet fuel显示文摘Synthesizing high-density fuel from lignocellulose can not only achieve green and low-carbon development,but also expand the feedstock source of hydrocarbon fuel.Here,we reported a route of producing high-density fuel from lignin oil and hemicellulose derivative cyclopentanol through alkylation and hydrodeoxygenation,HY with SiO_(2)/Al_(2)O_(3) molar ratio of 5.3 was screened as the alkylation catalyst in the reaction of model phenolic compounds and mixtures,and the reaction conditions were optimized to achieve conversion of phenolic compounds higher than 87%and selectivity of bicyclic and tricyclic products higher than 99%.Then two phenolic pools simulating the composition of two typic lignin oils were studied to validate the alkylation and analyze the competition mechanism of phenolic compounds in mixture system.Finally,real lignin oil from depolymerized of beech powder was tested,and notably80%of phenolic monomers in the oil were converted into fuel precursor.After hydrodeoxygenation,the alkylated product was converted to fuel blend with a density of 0.91 g/mL at 20℃and a freezing point lower than-60℃,very promising as high density fuel.This work provides a facile and energyefficient way of synthesizing high-performance jet fuel directly from lignocellulosic derivatives,which decreases processing energy consumption and improve the utilization rate of feedstock.Sichao Yang Chengxiang Shi Zhensheng Shen Lun Pan Zhenfeng Huang Xiangwen Zhang Ji-Jun Zou 2023Journal of Energy Chemistry2023,,2:1
4Large-scale roll-to-roll printed,flexible and stable organic bulk heterojunction photodetector显示文摘A flexible and stable photodetector shows great potential applications in intelligent wearable devices,health monitoring,and biological sensing.The high-output fabrication of flexible and stable photodetector via the large-scale printing process would accelerate its commercialization.Herein,a high performance,flexible organic bulk heterojunction(BHJ)photodetector with good stability is designed and fabricated via a large-scale roll-to-roll(R2R)micro-gravure printing technique on polyethylene terephthalate(PET)or paper substrate,in which the organic BHJ active layer is structured with[6,6]-phenyl C_(61)butyric acid methyl ester(PCBM)and a donor-acceptor copolymer,i.e.,employing 4,8-bis(2-ethylhexylthiophene)benzo[1,2-b;3,4-b′]dithiophene(BDTT)as the donor unit and 5,8-bis(5-thiophen-2-yl)-6,7-difluoro-2,3-bis(4-ethylhexyloxy-1-mata-luorophenyl)quinoxaline(ffQx)as the acceptor unit(PBDTT-ffQx).The PBDTT-ffQx/PCBM BHJ photodetector shows a broad photoresponse in ultraviolet and visible light,a high detectivity(D^(*))value up to 6.19×10^(11)Jones,and an excellent Iphoto/Idark as high as 5.6×10^(2).It exhibits excellent flexibility and stability.Its performance parameters could maintain over 80%of original values after bending 10,000 cycles or exposing in ambient condition(humidity~50%,temperature~30℃)for 50 days without any encapsulation.More importantly,the R2R micro-gravure printed PBDTT-ffQx/PCBM BHJ active layer is great homogeneous,and the responsivity(R)values of photodetector arrays show a very narrow distribution.The research results show that a high-performance PBDTT-ffQx/PCBM BHJ photodetector with well reliability and reproducibility can be fabricated via the R2R micro-gravure printing technique,which provides an available strategy for fabricating large-area and flexible electronic and optoelectronic devices.Sichao Tong Jun Yuan Chujun Zhang Chunhua Wang Baoxing Liu Jianqiang Shen Huayan Xia Yingping Zou Haipeng Xie Jia Sun Si Xiao Jun He Yongli Gao Junliang Yang 2018npj Flexible Electronics2018,2,1:0
5Performance and mechanism of La-Fe metal-organic framework as a highly efficient adsorbent for fluoride removal from mine water显示文摘Water fluoride pollution has caused non-negligible harm to the environment and humans,and thus it is crucial to find a suitable treatment technology.In this study,La-Fe@PTA adsorbent was synthesized for the defluoridation of mine water.The results showed that the optimum conditions for defluoridation by La-Fe@PTA were p H close to 7.0,the initial F-concentration of 10 mg/L,the dosage of 0.5 g/L and the adsorption time of 240 min.Compared with SO_4^(2-),Cl^(-),NO_(3)^(-),Ca^(2+)and Mg^(2+),CO_(3)^(2-)and HCO_(3)^(-)presented severer inhibition on fluoride uptake by La-Fe@PTA.The adsorption process fits well with the pseudo-second-order kinetic model and Freundlich model,and the maximum adsorption capacity of Langmuir model was 95 mg/g.Fixed-bed adsorption results indicated that fluoride in practical fluorinated mine water could be effectively removed from 3.6 mg/L to less than 1.5 mg/L within130 bed volume(BV)by using 1.5 g La-Fe@PTA.Furthermore,the adsorbent still had good adsorption capacity after regeneration,which confirms the great application potential of La-Fe@PTA as a fluoride ion adsorbent.The mechanism analysis showed that La-Fe@PTA adsorption of fluorine ions is a physicochemical reaction driven by electrostatic attraction and ion exchange.Chaomin Jia Jianbing Wang Huijiao Wang Sichao Zhu Xiaohui Zhang Yuxiang Wang 2024Journal of Environmental Sciences2024,,5:0
6A novel electro-Fenton hybrid system for enhancing the interception of volatile organic compounds in membrane distillation desalination显示文摘Membrane distillation(MD)is a promising alternative desalination technology,but the hydrophobic membrane cannot intercept volatile organic compounds(VOCs),resulting in aggravation in the quality of permeate.In term of this,electro-Fenton(EF)was coupled with sweeping gas membrane distillation(SGMD)in a more efficient way to construct an advanced oxidation barrier at the gas-liquid interface,so that the VOCs could be trapped in this layer to guarantee the water quality of the distillate.During the so-called EF-MD process,an interfacial interception barrier containing hydroxyl radical formed on the hydrophobic membrane surface.It contributed to the high phenol rejection of 90.2% with the permeate phenol concentration lower than 1.50 mg/L.Effective interceptions can be achieved in a wide temperature range,even though the permeate flux of phenol was also intensified.The EF-MD system was robust to high salinity and could electrochemically regenerate ferrous ions,which endowed the long-term stability of the system.This novel EF-MD configuration proposed a valuable strategy to intercept VOCs in MD and will broaden the application of MD in hypersaline wastewater treatment.Hongxin Liu Kuiling Li Kunpeng Wang Zhiyong Wang Zimou Liu Sichao Zhu Dan Qu Yu Zhang Jun Wang 2024Journal of Environmental Sciences2024,,4:0

9Exploring self-organization and self-adaption for smart manufacturing complex networks显示文摘Trends toward the globalization of the manufacturing industry and the increasing demands for small-batch,short-cycle,and highly customized products result in complexities and fluctuations in both external and internal manufacturing environments,which poses great challenges to manufacturing enterprises.Fortunately,recent advances in the Industrial Internet of Things(IIoT)and the widespread use of embedded processors and sensors in factories enable collecting real-time manufacturing status data and building cyber–physical systems for smart,flexible,and resilient manufacturing systems.In this context,this paper investigates the mechanisms and methodology of self-organization and self-adaption to tackle exceptions and disturbances in discrete manufacturing processes.Specifically,a general model of smart manufacturing complex networks is constructed using scale-free networks to interconnect heterogeneous manufacturing resources represented by network vertices at multiple levels.Moreover,the capabilities of physical manufacturing resources are encapsulated into virtual manufacturing services using cloud technology,which can be added to or removed from the networks in a plug-and-play manner.Materials,information,and financial assets are passed through interactive links across the networks.Subsequently,analytical target cascading is used to formulate the processes of self-organizing optimal configuration and self-adaptive collaborative control for multilevel key manufacturing resources while particle swarm optimization is used to solve local problems on network vertices.Consequently,an industrial case based on a Chinese engine factory demonstrates the feasibility and efficiency of the proposed model and method in handling typical exceptions.The simulation results show that the proposed mechanism and method outperform the event-triggered rescheduling method,reducing manufacturing cost,manufacturing time,waiting time,and energy consumption,with reasonable computational time.This work potentially enables managers and practitioners to implement active perception,active response,self-organization,and self-adaption solutions in discrete manufacturing enterprises.Zhengang GUO Yingfeng ZHANG Sichao LIU Xi Vincent WANG Lihui WANG 2023Frontiers of Engineering Management2023,10,2:0
10High-precision Calibration of Camera and IMU on Manipulator for Bio-inspired Robotic System显示文摘Inspired by box jellyfish that has distributed and complementary perceptive system,we seek to equip manipulator with a camera and an Inertial Measurement Unit(IMU)to perceive ego motion and surrounding unstructured environment.Before robot perception,a reliable and high-precision calibration between camera,IMU and manipulator is a critical prerequisite.This paper introduces a novel calibration system.First,we seek to correlate the spatial relationship between the sensing units and manipulator in a joint framework.Second,the manipulator moving trajectory is elaborately designed in a spiral pattern that enables full excitations on yaw-pitch-roll rotations and x-y-z translations in a repeatable and consistent manner.The calibration has been evaluated on our collected visual inertial-manipulator dataset.The systematic comparisons and analysis indicate the consistency,precision and effectiveness of our proposed calibration method.Yinlong Zhang Wei Liang Sichao Zhang Xudong Yuan Xiaofang Xia Jindong Tan Zhibo Pang 2022Journal of Bionic Engineering2022,19,2:0
11Composition analysis of Compound Shenhua Tablet,a seven-herb Chinese medicine for IgA nephropathy:evaluation of analyte-capacity of the assays显示文摘Compound Shenhua Tablet,a medicine comprising seven herbs,is employed in treating IgA nephropathy.This study aimed to meticulously analyze its chemical composition.Based on a list of candidate compounds,identified through extensive literature review pertinent to the tablet’s herbal components,the composition analysis entailed the systematic identification,characterization,and quantification of the constituents.The analyte-capacity of LC/ESI-MS-based and GC/EI-MS-based assays was evaluated.The identified and characterized constituents were quantified to determine their content levels and were ranked based on the constituents’daily doses.A total of 283 constituents,classified into 12 distinct categories,were identified and characterized in the Compound Shenhua Tablet.These constituents exhibited content levels of 1−10982μg·g^(−1),with daily doses of 0.01−395μmol·d^(−1).The predominant constituents,with daily doses of≥10μmol·d^(−1),include nine organic acids(citric acid,quinic acid,chlorogenic acid,cryptochlorogenic acid,gallic acid,neochlorogenic acid,isochlorogenic acid C,isochlorogenic acid B,and linoleic acid),five iridoids(specnuezhenide,nuezhenoside G13,nuezhenidic acid,secoxyloganin,and secologanoside),two monoterpene glycosides(paeoniflorin and albiflorin),a sesquiterpenoid(curzerenone),a triterpenoid(oleanolic acid),and a phenylethanoid(salidroside).Additionally,there were 83,126,and 55 constituents detected in the medicine with daily doses of 1–10,0.1–1,and 0.01–0.1μmol·d^(−1),respectively.The combination of the LC/ESI-MS-based and GC/EI-MS-based assays demonstrated a complementary relationship in their analyte-capacity for detecting the constituents present in the medicine.This comprehensive composition analysis establishes a solid foundation for further pharmacological research on Compound Shenhua Tablet and facilitates the quality evaluation of this complex herbal medicine.ZHANG Haiyan WANG Qiuyue WANG Jianan ZHANG Sichao JIA Weiwei HE Ning XIA Xiaoyan WANG Ting LAI Liyu LI Jiaying DU Jing OLALEYE Olajide E CHEN Xiangmei YANG Junling LI Chuan 2024Chinese Journal of Natural Medicines2024,22,2:0
12Host-induced gene silencing of multiple pathogenic factors of Sclerotinia sclerotiorum confers resistance to Sclerotinia rot in Brassica napus显示文摘Sclerotinia sclerotiorum is generally considered one of the most economically damaging pathogens in oilseed rape(Brassica napus).Breeding for Sclerotinia resistance is challenging,as no immune germplasm available in B.napus.It is desirable to develop new breeding strategies.In the present study,hostinduced gene silencing(HIGS),developed based on RNA interference(RNAi),was applied to protect B.napus from S.sclerotiorum infection.Three pathogenicity genes,the endo-polygalacturonase gene(Ss PG1),cellobiohydrolase gene(Ss CBH),and oxaloacetate acetylhydrolase gene(Ss OAH1),were chosen as HIGS targets.Co-incubation of synthesized double-stranded RNAs(ds RNAs)with S.sclerotiorum in liquid medium significantly reduced the transcript levels of the target genes.Application to plant surfaces of ds RNA targeting the three genes conferred effective protection against S.sclerotiorum.Stable transgenic B.napus plants expressing small interfering RNAs with sequence identity to Ss PG1,Ss CBH,and Ss OAH1 were generated.HIGS transgenic B.napus prevented the expression of S.sclerotiorum target genes,slowed pathogenicity-factor accumulation,impeded fungal growth,and suppressed appressorium formation,thereby conferring resistance to S.sclerotiorum.Simultaneous silencing of Ss PG1,Ss CBH,and Ss OAH1 by stable expression of a chimeric hairpin RNAi construct in B.napus led to enhanced protection phenotypes(with disease lesion size reduced by 36.8%–43.7%).We conclude that HIGS of pathogenic-factor genes of S.sclerotiorum is a promising strategy for controlling Sclerotinia rot in oilseed rape.Jian Wu Shengliang Yin Li Lin Dongxiao Liu Sichao Ren Wenjing Zhang Wencheng Meng Peipei Chen Qinfu Sun Yujie Fang Cunxu Wei Youping Wang 2022The Crop Journal2022,10,3:0
