1Consensus on the application of negative pressure wound therapy of diabetic foot wounds显示文摘Because China is becoming an aging society,the incidence of diabetes and diabetic foot have been increasing.Diabetic foot has become one of the main health-related killers due to its high disability and mortality rates.Negative pressure wound therapy(NPWT)is one of the most effective techniques for the treatment of diabetic foot wounds and great progress,both in terms of research and its clinical application,has been made in the last 20 years of its development.However,due to the complex pathogenesis and management of diabetic foot,irregular application of NPWT often leads to complications,such as infection,bleeding and necrosis,that seriously affect its treatment outcomes.In 2020,under the leadership of Burns,Trauma and Tissue Repair Committee of the Cross-Straits Medicine Exchange Association,the writing group for‘Consensus on the application of negative pressure wound therapy of diabetic foot wounds’was established with the participation of scholars from the specialized areas of burns,endocrinology,vascular surgery,orthopedics and wound repair.Drawing on evidence-based practice suggested by the latest clinical research,this consensus proposes the best clinical practice guidelines for the application and prognostic evaluation of NPWT for diabetic foot.The consensus aims to support the formation of standardized treatment schemes that clinicians can refer to when treating cases of diabetic foot.Shizhao Ji Xiaobin Liu Jie Huang Junmin Bao Zhaohong Chen Chunmao Han Daifeng Hao Jingsong Hong Dahai Hu Yufeng Jiang Shang Ju Hongye Li Zongyu Li Guangping Liang Yan Liu Gaoxing Luo Guozhong Lv Xingwu Ran Zhongmin Shi Juyu Tang Aiping Wang Guangyi Wang Jiangning Wang Xin Wang Bing Wen Jun Wu Hailin Xu Maojin Xu Xiaofei Ye Liangxi Yuan Yi Zhang Shichu Xiao Zhaofan Xia 2021Burns & Trauma2021,9,1:17
2The OsAMT1.1 gene functions in ammonium uptake and ammoniumepotassium homeostasis over low and high ammonium concentration ranges显示文摘Rice(Oryza sativa) grown in paddy fields is an ammonium(NH^+_4)-preferring crop;however,its AMT-type NH^+_4transporters that mediate root N acquisition have not been well characterized yet.In this study,we analyzed the expression pattern and physiological function of the OsAMT1.1 gene of the AMT1 subfamily in rice.Os AMT1.1 is located in the plasma membrane and is mainly expressed in the root epidermis,stele and mesophyll cells.Disruption of the Os AMT1.1 gene decreased the uptake of NH^+_4,and the growth of roots and shoots under both low NH^+_4and high NH^+_4conditions.Os AMT1.1 contributed to the short-term(5 min)^(15)NH^+_4influx rate by approximately one-quarter,irrespective of the NH^+_4concentration.Knockout of Os AMT1.1 significantly decreased the total N transport from roots to shoots under low NH^+_4conditions.Moreover,compared with the wild type,the osamt1.1 mutant showed an increase in the potassium(K)absorption rate under high NH^+_4conditions and a decrease under low NH^+_4conditions.The mutants contained a significantly high concentration of K in both the roots and shoots at a limited K(0.1 mmol/L)supply when NH^+_4was replete.Taken together,the results indicated that OsAMT1.1 significantly contributes to the NH^+_4uptake under both low and high NH^+_4conditions and plays an important role in Ne K homeostasis in rice.Chang Li Zhong Tang Jia Wei Hongye Qu Yanjie Xie Guohua Xu 2016Journal of Genetics and Genomics2016,43,11:12
3Dosage effect of multiple genes accounts for multisystem disorder of myotonic dystrophy type 1显示文摘Multisystem manifestations in myotonic dystrophy type 1(DM1)may be due to dosage reduction in multiple genes induced by aberrant expansion of CTG repeats in DMPK,including DMPK,its neighboring genes(SIX5 or DMWD)and downstream MBNLh However,direct evidence is lacking.Here,we develop a new strategy to generate mice carrying multigene heterozygous mutations to mimic dosage reduction in one step by injection of haploid embryonic stem cells with mutant Dmpk,Six5 and Mbnll into oocytes.The triple heterozygous mutant mice exhibit adult-onset DM1 phenotypes.With the additional mutation in Dmwd,the quadruple heterozygous mutant mice recapitulate many major manifestations in congenital DM1.Moreover,muscle stem cells in both models display reduced sternness,providing a unique model for screening small molecules for treatment of DM1.Our results suggest that the complex symptoms of DM1 result from the reduced dosage of multiple genes.Qi Yin Hongye Wang Na Li Yifu Ding Zhenfei Xie Lifang Jin Yan Li Qiong Wang Xinyi Liu Liuqing Xu Qing Li Yongjian Ma Yanbo Cheng Kai Wang Cuiqing Zhong Qian Yu Wei Tang Wanjin Chen Wenjun Yang Fan Zhang Chen Ding Lan Bao Bin Zhou Ping Hu Jinsong Li 2020Cell Research2020,30,2:7
4Tuning Atomically Dispersed Fe Sites in Metal–Organic Frameworks Boosts Peroxidase‑Like Activity for Sensitive Biosensing显示文摘Although nanozymes have been widely developed,accurate design of highly active sites at the atomic level to mimic the electronic and geometrical structure of enzymes and the exploration of underlying mechanisms still face significant challenges.Herein,two functional groups with opposite electron modulation abilities(nitro and amino)were introduced into the metal–organic frameworks(MIL-101(Fe))to tune the atomically dispersed metal sites and thus regulate the enzymelike activity.Notably,the functionalization of nitro can enhance the peroxidase(POD)-like activity of MIL-101(Fe),while the amino is poles apart.Theoretical calculations demonstrate that the introduction of nitro can not only regulate the geometry of adsorbed intermediates but also improve the electronic structure of metal active sites.Benefiting from both geometric and electronic effects,the nitro-functionalized MIL-101(Fe)with a low reaction energy barrier for the HO*formation exhibits a superior POD-like activity.As a concept of the application,a nitro-functionalized MIL-101(Fe)-based biosensor was elaborately applied for the sensitive detection of acetylcholinesterase activity in the range of 0.2–50 mU mL−1 with a limit of detection of 0.14 mU mL−1.Moreover,the detection of organophosphorus pesticides was also achieved.This work not only opens up new prospects for the rational design of highly active nanozymes at the atomic scale but also enhances the performance of nanozyme-based biosensors.Weiqing Xu Yikun Kang Lei Jiao Yu Wu Hongye Yan Jinli Li Wenling Gu Weiyu Song Chengzhou Zhu 2020Nano-Micro Letters2020,12,12:4
5Pd nanoparticles immobilized on graphite oxide modified with a base: Highly efficient catalysts for selective hydrogenation of citral显示文摘In this work, the Pd-based catalysts were designed via immobilizing Pd nanoparticles on graphite oxide (GO) modified with organic base, 1,1,3,3-tetramethylguanidine (TMG), which was used for the selective hydrogenation of citral. These catalysts were characterized by various techniques including IR, X-ray diffraction, transmission electron microscopy, and X-ray photoelectron spectroscopy. It was demonstrated that the Pd particles with size less than 5 nm were uniformly distributed throughout the support, and they were in the electron-deficient state due to the strong interactions with the modified support. The resultant Pd-TMG/GO catalyst displayed high efficiency for the selective hydrogenation of citral with a turnover frequency of 7100 h-1 as well as superior selectivity to citronellal of 89.6%. Moreover, the catalyst can be reused for five times without obvious activity loss, which may result from its stable structure.ZHAO YanFei ZHANG HongYe HUANG ChangLiang CHEN Sha YU Bo XU JiLei LIU ZhiMin 2013Science China Chemistry2013,56,2:3
6Rotational Friction Damper’s Performance for Controlling Seismic Response of High Speed Railway Bridge-Track System显示文摘CRTS-II slab ballastless track on bridge is a unique system in China high speed railway.The application of longitudinal continuous track system has obviously changed dynamic characteristics of bridge structure.The bridge system and CRTS-II track system form a complex nonlinear system.To investigate the seismic response of high speed railway(HSR)simply supported bridge-track system,nonlinear models of three-span simply supported bridge with piers of different height and CRTS-II slab ballastless track system are established.By seismic analysis,it is found that shear alveolar in CRTS-II track system is more prone to be damaged than bridge components,such as piers,girders and bearings.The result shows that the inconsistent displacement of bridge girders is the main cause of the CRTS-II track system’s damage.Then the rotational friction damper(RFD)is adopted,which utilizes the device’s rotation and friction to dissipate seismic energy.The hysteretic behavior of RFD is studied by numerical and experimental methods.Results prove that RFD can provide good hysteretic energy dissipation ability with stable performance.Furthermore,the analysis of RFD’s influence on seismic response of HSR bridge-track system shows that RFD with larger sliding force is more effective in controlling excessive inconsistent displacement where RFD is installed,though response of other bridge spans could slightly deteriorated.Wei Guo Chen Zeng Hongye Gou Yao Hu Hengchao Xu Longlong Guo 2019Computer Modeling in Engineering & Sciences2019,,9:3
7One-step preparation of branched PEG functionalized AIE-active luminescent polymeric nanoprobes显示文摘The synthesis of amphiphilic aggregation-induced emission(AIE) dyes based organic nanoparticles has recently attracted increasing attention in the biomedical fields. These AIE dyes based nanoparticles could effectively overcome the aggregation caused quenching effect of conventional organic dyes, making them promising candidates for fabrication of ultrabright organic luminescent nanomaterials. In this work, AIE-active luminescent polymeric nanoparticles(4-NH_2-PEG-TPE-E LPNs) were facilely fabricated through Michael addition reaction between tetraphenylethene acrylate(TPE-E) and 4-arm-poly(ethylene glycol)-amine(4-NH_2-PEG) in rather mild ambient. The 4-NH_2-PEG can not only endow these AIE-active LPNs good water dispersibility, but also provide functional groups for further conjugation reaction. The size, morphology and luminescent properties of 4-NH_2-PEG-TPE-E LPNs were characterized by a series of techniques in detail. Results suggested that these AIE-active LPNs showed spherical morphology with diameter about 100–200 nm. The obtained 4-NH_2-PEG-TPE-E LPNs display high water dispersibility and strong fluorescence intensity because of their self assembly and AIE properties of TPE-E.Biological evaluation results demonstrated that 4-NH_2-PEG-TPE-E LPNs showed negative toxicity toward cancer cells and good fluorescent imaging performance. All of these features make 4-NH_2-PEG-TPE-E LPNs promising candidates for biological imaging and therapeutic applications.Jun Chu Qiulan Lv Chunliang Guo Dazhuang Xu Ke Wang Meiying Liu Hongye Huang Xiaoyong Zhang Yen Wei 2016Science China Chemistry2016,59,8:2
8Magnetic properties and magnetic entropy change of perovskite manganites La_(0.9-x)Eu_xSr_(0.1)MnO_3(x=0.000,0.075) by experimental method and numerical fitting显示文摘Polycrystalline samples La_(0.9-x)EuxSr_(0.1)MnO_3(x = 0.000, 0.075) were prepared by the standard solid-state reaction method. The results show that the samples preform a characteristic of clusters spin-glass state at low temperature. The samples show a characteristic of ferromagnetism(FM) characteristic in the temperature range of 15-125 K and 15-150 K respectively; the samples show preformed clusters in the temperature range of 125-343 K and 150-325 K, respectively, the samples show paramagnetism(PM)characteristic above 343 and 325 K, respectively. The second-order transitions are found at 118 and 135 K for undoped and doped sample, respectively. When the applied magnetic field is 7 T, the maximum magnetic entropy change |△S_M| value of the samples is near the Curie temperature(Tc), and the value of|△S_M| reaches 2.76 and 3.03 J/(K kg), respectively. In addition, the relative cooling power(RCP) is found to be 425.28 and 443.53 J/kg. The numerical fitting data fit well with experimental data. These results indicate that both the samples have the potential to realize magnetic refrigeration in the high temperature region(T > 77 K).Xiang Jin Jianjun Zhao Hongye Wu Bao Xu Yunbin Sun Xiaodong Sun Fengze Cao Kai Wang Wenxing Wang Yutong Zhang Yi Lu 2019Journal of Rare Earths2019,37,6:1

10Defect-rich and ultrathin nitrogen-doped carbon nanosheets with enhanced peroxidase-like activity for the detection of urease activity and fluoride ion显示文摘Although carbon nanozymes have attracted great interest due to their good biocompatibility, low cost,and high stability, designing high-active carbon nanozymes still faces great challenges. Herein, ultrathin nitrogen-doped carbon nanosheets with rich defects(d-NC) were prepared through a high-temperature annealing process, using potassium chloride and ammonium chloride as templates. Owing to the large specific surface area, rich defects and the high exposure of active sites, the proposed d-NC nanozymes exhibited excellent peroxidase-like activity. The d-NC nanozymes possess maximal reaction velocity and their specific activity is 9.4-fold higher than that of nitrogen-doped carbon nanozymes, indicating that the induced defects can boost the catalytic performance. Benefited from the good peroxidase-like activities of d-NC nanozymes, the colorimetric sensing platforms were constructed for the detection of urease activity and fluoride ion, exhibiting satisfactory stability and selectivity. This study not only offers a way to synthesize carbon nanozymes with improved enzyme-like activities but also broadens their applications in colorimetric biosensing.Yu Zhang Lei Jiao Weiqing Xu Yifeng Chen Yu Wu Hongye Yan Wenling Gu Chengzhou Zhu 2022Chinese Chemical Letters2022,33,3:1

13Kinetic model for hydroisomerization reaction of C_(8)-aromatics显示文摘Based on the reported reaction networks,a novel six-component hydroisomerization reaction net-work with a new lumped species including C_(8)-naphthenes and C_(8)-paraffins is proposed and a kinetic model for a commercial unit is also developed.An empirical catalyst deactivation function is incorporated into the model accounting for the loss in activity because of coke forma-tion on the catalyst surface during the long-term opera-tion.The Runge-Kutta method is used to solve the ordinary differential equations of the model.The reaction kinetic parameters are benchmarked with several sets of balanced plant data and estimated by the differential vari-able metric optimization method(BFGS).The kinetic model is validated by an industrial unit with sets of plant data under different operating conditions and simulation results show a good agreement between the model predic-tions and the plant observations.Ouguan XU Hongye SU Xiaoming JIN Jian CHU 2008Frontiers of Chemical Science and Engineering2008,2,1:0
14Fine-Tuning Pyridinic Nitrogen in Nitrogen-Doped Porous Carbon Nanostructures for Boosted Peroxidase-Like Activity and Sensitive Biosensing显示文摘Carbon materials have been widely used as nanozymes in bioapplications,attributing to their intrinsic enzyme-like activities.Nitrogen(N)-doping has been explored as a promising way to improve the activity of carbon material-based nanozymes(CMNs).However,hindered by the intricate N dopants,the real active site of N-doped CMNs(N-CMNs)has been rarely investigated,which subsequently retards the further progress of high-performance N-CMNs.Here,a series of porous N-CMNs with well-controlled N dopants were synthesized,of which the intrinsic peroxidase(POD)like activity has a positive correlation with the pyridinic N content.Density functional theory calculations also reveal that pyridinic N boosts the intrinsic POD-like activity of N-CMNs.Pyridinic-N dopant can effectively promote the first H_(2)O desorption process in comparison with the graphitic and pyrrolic N,which is the key endothermic reaction during the catalytic process.Then,utilizing the optimized nanozymes with high pyridinic N content(NP-CMNs)and superior POD-like activity,a facile total antioxidant capacity(TAC)assay was developed,holding great promise in the quality assessment of medicine tablets and antioxidant food for healthcare and healthy diet.Hongye Yan Linzhe Wang Yifeng Chen Lei Jiao Yu Wu Weiqing Xu Wenling Gu Weiyu Song Dan Du Chengzhou Zhu 2020Research2020,,1:0
15CO_(2)corrosion prediction on 20#steel under the influence of corrosion product film显示文摘Based on corrosion thermodynamics and kinetics,considering the multi-field coupling effects of fluid flow,electrochemical reaction and mass transfer process,a new corrosion prediction mechanistic model was proposed by introducing the influence factor of corrosion product film on diffusion coefficient of ion mass transfer,which is based on the CO_(2) corrosion prediction model proposed by Nesic et al.The influence of temperature,flow rate and pH value on CO_(2) corrosion behavior on 20#steel was studied by orthogonal tests.Scanning electron microscopy(SEM)and energy spectrum analysis(EDS)was used to analyze the surface and cross section morphology of the corrosion product film,and the thickness of the corrosion product film was measured.The results show that the introduced influence factor can simplify the ion mass transfer calculation in the presence of corrosion product film,and the relative error between the predicted value of the modified model and the experimental results is satisfactorily controlled less than 10%.Compared with the prediction model without considering the influence of corrosion product film,the influence factor can effectively correct the high prediction value of the mechanistic model under the influence of corrosion product film,improve the accuracy and applicability of corrosion prediction,and provide important theoretical guidance for the design,manufacturing,operation and maintenance of oil and gas production pipelines and related facilities.Yingxue Liu Hongye Jiang Taolong Xu Youlv Li 2023Petroleum2023,9,3:0
16The functions of exosomes targeting astrocytes and astrocyte-derived exosomes targeting other cell types显示文摘Astrocytes are the most abundant glial cells in the central nervous system;they participate in crucial biological processes,maintain brain structure,and regulate nervous system function.Exosomes are cell-derived extracellular vesicles containing various bioactive molecules including proteins,peptides,nucleotides,and lipids secreted from their cellular sources.Increasing evidence shows that exosomes participate in a communication network in the nervous system,in which astrocyte-derived exosomes play important roles.In this review,we have summarized the effects of exosomes targeting astrocytes and the astrocyte-derived exosomes targeting other cell types in the central nervous system.We also discuss the potential research directions of the exosome-based communication network in the nervous system.The exosome-based intercellular communication focused on astrocytes is of great significance to the biological and/or pathological processes in different conditions in the brain.New strategies may be developed for the diagnosis and treatment of neurological disorders by focusing on astrocytes as the central cells and utilizing exosomes as communication mediators.Hongye Xu He Li Ping Zhang Yuan Gao Hongyu Ma Tianxiang Gao Hanchen Liu Weilong Hua Lei Zhang Xiaoxi Zhang Pengfei Yang Jianmin Liu 2024Neural Regeneration Research2024,19,9:0
17Research on the evolutionary characteristics of evaluation policies of Chinese science and technology talents显示文摘Science and technology talent evaluation is an important part of the talent development system and mechanism,and the state's emphasis on science and technology talent evaluation is reflect-ed in the national policy.This paper takes 49 policy documents on science and technology tal-ent evaluation issued by the state from 1978 to 2022 as the object,and uses policy text analysis,word frequency analysis and co-word network analysis to interpret the content of the policies.These policy texts are divided into four stages.200 high-frequency words were extracted from the policies in each stage after word segmentation was made,and the co-word matrixes and co-word networks were constructed for each stage.The research draws the following conclu-sions:1)The content of Chinese science and technology talent evaluation policies is gradually becoming concrete,and the concept of science and technology talent evaluation is gradually clear;2)The policies have transitioned from'scientific and technological development'to'sci-entific and technological innovation';3)The distribution of policies with different strengths is uneven;4)The cooperation between all departments involved in policy formulation is not e-nough.Xu Wang Hongye Li 2023Data Science and Informetrics2023,3,3:0

19Activation of NRF2 by celastrol increases antioxidant functions and prevents the progression of osteoarthritis in mice显示文摘Excessive oxidative stress impairs cartilage matrix metabolism balance,significantly contributing to osteoarthritis(OA)development.Celastrol(CSL),a drug derived from Tripterygium wilfordii,has recognized applications in the treatment of cancer and immune system disorders,yet its antioxidative stress mechanisms in OA remain underexplored.This study aimed to substantiate CSL’s chondroprotective effects and unravel its underlying mechanisms.We investigated CSL’s impact on chondrocytes under both normal and inflammatory conditions.In vitro,CSL mitigated interleukin(IL)-1β-induced activation of proteinases and promoted cartilage extracellular matrix(ECM)synthesis.In vivo,intra-articular injection of CSL ameliorated cartilage degeneration and mitigated subchondral bone lesions in OA mice.Mechanistically,it was found that inhibiting nuclear factor erythroid 2-related factor 2(NRF2)abrogated CSL-mediated antioxidative functions and exacerbated the progression of OA.This study is the first to elucidate the role of CSL in the treatment of OA through the activation of NRF2,offering a novel therapeutic avenue for arthritis therapy.LIU Mingming GUO Jiatian ZHAO Jing LI Hongye FENG Xiaoxiao LIU Haojun ZHANG Hao JIA Xuejun WEI Rushuai LI Fang CHEN Chong HOU Mingzhuang LV Nanning XU Haiyan 2024Chinese Journal of Natural Medicines2024,22,2:0
