1Joint contractures in severe burn patients with early rehabilitation intervention in one of the largest burn intensive care unit in China:a descriptive analysis显示文摘Background:Joint contracture is the major clinical complication in burn patients,especially,the severe burn patients.This study aimed to investigate the number and severity of joint contractures in patients with burns affecting greater than or equal to 50%of the total body surface area(TBSA)undergoing early rehabilitation in a burn intensive care unit(BICU).Methods:We analyzed burn patients with burns affecting greater than or equal to 50%of the TBSA admitted to a BICU who received early rehabilitation within 7 days post-injury from January 2011 to December 2015.Demographic and medical information was collected.The range of motion(ROM)of different joints was measured 1 month post-admission.Spearman’s correlation coefficient and logistic regression analysis was used to determine predictors of the presence and severity of contractures.Result:The average affected TBSA of the included burn patients was 67.4%,and the average length of stay in the BICU was 46.2±28.8 days.One hundred and one of 108 burn patients(93.5%)developed at least one joint contracture.The ROM in 67.9%of the affected joints was mildly limited.The majority of contractures in severe burn patients were mild(37.7%)or moderate(33.2%).The wrist was the most commonly affected joint(18.2%),followed by the shoulder,ankle,hip,knee,and elbow.A predictor of the presence of contractures was the length of hospital stay(p=0.049).The severe contracture was related to the area of full-thickness burns,the strict bed rest time,and the duration of rehabilitation in BICU.The length of rehabilitation stay(days)in patients with moderate contracture is 54.5%longer than that in severe contracture(p=0.024)Conclusion:During the long stay in BICU,the length of rehabilitation stay in a BICU could decrease the severity of contractures from severe to moderate in the patients with equal to 50%of the TBSA.Hence,this research reveals the important role of early rehabilitation interventions in severe burn patients.Jianglin Tan Jian Chen Junyi Zhou Huapei Song Huan Deng Ming Ao Gaoxing Luo Jun Wu 2019Burns & Trauma2019,7,1:9
2Allogeneic Vγ9Vδ2 T-cell immunotherapy exhibits promising clinical safety and prolongs the survival of patients with late-stage lung or liver cancer显示文摘Vγ9Vδ2 T cells are promising candidates for cellular tumor immunotherapy.Due to their HLA-independent mode of action,allogeneic Vγ9Vδ2 T cells can be considered for clinical application.To apply allogeneic Vγ9Vδ2 T cells in adoptive immunotherapy,the methodology used to obtain adequate cell numbers with optimal effector function in vitro needs to be optimized,and clinical safety and efficacy also need to be proven.Therefore,we developed a novel formula to improve the expansion of peripheralγδT cells from healthy donors.Then,we used a humanized mouse model to validate the therapeutic efficacy of expandedγδT cells in vivo;furthermore,the expandedγδT cells were adoptively transferred into late-stage liver and lung cancer patients.We found that the expanded cells possessed significantly improved immune effector functions,including proliferation,differentiation,and cancer cell killing,both in vitro and in the humanized mouse model.Furthermore,a phase I clinical trial in 132 late-stage cancer patients with a total of 414 cell infusions unequivocally validated the clinical safety of allogeneic Vγ9Vδ2 T cells.Among these 132 patients,8 liver cancer patients and 10 lung cancer patients who received≥5 cell infusions showed greatly prolonged survival,which preliminarily verified the efficacy of allogeneic Vγ9Vδ2 T-cell therapy.Our clinical studies underscore the safety and efficacy of allogeneic Vγ9Vδ2 T-cell immunotherapy,which will inspire further clinical investigations and eventually benefit cancer patients.Yan Xu Zheng Xiang Mohammed Alnaggar Léonce Kouakanou Jiawei Li Junyi He Jiashuang Yang Yi Hu Yan Chen Li Lin Jianlei Hao Jingxia Li Jibing Chen Man Li Qingling Wu Christian Peters Qinghua Zhou Jianshuang Li Yingqing Liang Xiaohua Wang Baohui Han Meili Ma Dieter Kabelitz Kecheng Xu Wenwei Tu Yangzhe Wu Zhinan Yin 2021Cellular & Molecular Immunology2021,18,2:8
3Sox9 augments BMP2-induced chondrogenic differentiation by downregulating Smad7 in mesenchymal stem cells(MSCs)显示文摘Cartilage injuries caused by arthritis or trauma pose formidable challenges for effective clinical management due to the limited intrinsic proliferative capability of chondrocytes.Autologous stem cell-based therapies and transgene-enhanced cartilage tissue engineering may open new avenues for the treatment of cartilage injuries.Bone morphogenetic protein 2(BMP2)induces effective chondrogenesis of mesenchymal stem cells(MSCs)and can thus be explored as a potential therapeutic agent for cartilage defect repair.However,BMP2 also induces robust endochondral ossification.Although the precise mechanisms through which BMP2 governs the divergence of chondrogenesis and osteogenesis remain to be fully understood,blocking endochondral ossification during BMP2-induced cartilage formation may have practical significance for cartilage tissue engineering.Here,we investigate the role of Sox9-donwregulated Smad7 in BMP2-induced chondrogenic differentiation of MSCs.We find that overexpression of Sox9 leads to a decrease in BMP2-induced Smad7 expression in MSCs.Sox9 inhibits BMP2-induced expression of osteopontin while enhancing the expression of chondrogenic marker Col2a1 in MSCs.Forced expression of Sox9 in MSCs promotes BMP2-induced chondrogenesis and suppresses BMP2-induced endochondral ossification.Constitutive Smad7 expression inhibits BMP2-induced chondrogenesis in stem cell implantation assay.Mouse limb explant assay reveals that Sox9 expands BMP2-stimulated chondrocyte proliferating zone while Smad7 promotes BMP2-intitated hypertrophic zone of the growth plate.Cell cycle analysis indicates that Smad7 induces significant early apoptosis in BMP2-stimulated MSCs.Taken together,our results strongly suggest that Sox9 may facilitate BMP2-induced chondrogenesis by downregulating Smad7,which can be exploited for effective cartilage tissue engineering.Chen Zhao Wei Jiang Nian Zhou Junyi Liao Mingming Yang Ning Hu Xi Liang Wei Xu Hong Chen Wei Liu Lewis L.Shi Leonardo Oliveira Jennifer Moriatis Wolf Sherwin Ho Aravind Athiviraham H.M.Tsai Tong-Chuan He Wei Huang 2017Genes & Diseases2017,4,4:7
4Thick Miocene eolian deposits on the Huajialing Mountains:The geomorphic evolution of the western Loess Plateau显示文摘The geomorphic evolution of northwestern China during the Cenozoic has been a subject of much geological interest because of its link with the uplift of the Himalayan-Tibetan complex.Much information about these changes is recoverable from the sedimentary sequences of the region.We report here on the thick eolian deposits mantling the Huajialing Mountains,a relatively flat mountain range in the western Loess Plateau.Correlation of magnetic susceptibility stratigraphy with the QA-I Miocene eolian sequence dates a 134.7 m section(NL-VII) for the interval from 18.7 to 11.8 Ma,as confirmed by micro-mammalian fossils.These eolian deposits demonstrate a much wider distribution of the Miocene eolian deposits,and also indicate that the topography contrasts in the western Loess Plateau,including the uplifts of the Huajialing Mountains and the bedrock highlands in the Qinan region,were formed by the early Miocene.The near-continuous Miocene eolian sequence from 18.7 to 11.8 Ma indicates that the substratum of Huajialing had not experienced any intense tectonic changes during this time interval,which suggests further,the relative tectonic stability of the nearby Tibetan Plateau.ZHAN Tao GUO ZhengTang WU HaiBin GE JunYi ZHOU Xin WU ChunLin ZENG FangMing 2011Science China Earth Sciences2011,54,2:7

6An all-round AI-Chemist with a scientific mind显示文摘The realization of automated chemical experiments by robots unveiled the prelude to an artificial intelligence(AI)laboratory.Several AI-based systems or robots with specific chemical skills have been demonstrated,but conducting all-round scientific research remains challenging.Here,we present an all-round AI-Chemist equipped with scientific data intelligence that is capable of performing basic tasks generally required in chemical research.Based on a service platform,the AI-Chemist is able to automatically read the literatures from a cloud database and propose experimental plans accordingly.It can control a mobile robot in-house or online to automatically execute the complete experimental process on 14 workstations,including synthesis,characterization and performance tests.The experimental data can be simultaneously analysed by the computational brain of the AI-Chemist through machine learning and Bayesian optimization,allowing a new hypothesis for the next iteration to be proposed.The competence of the AI-Chemist has been scrutinized by three different chemical tasks.In the future,the more advanced all-round AI-Chemists equipped with scientific data intelligence may cause changes to the landscape of the chemical laboratory.Qing Zhu Fei Zhang Yan Huang Hengyu Xiao LuYuan Zhao XuChun Zhang Tao Song XinSheng Tang Xiang Li Guo He BaoChen Chong JunYi Zhou YiHan Zhang Baicheng Zhang JiaQi Cao Man Luo Song Wang GuiLin Ye WanJun Zhang Xin Chen Shuang Cong Donglai Zhou Huirong Li Jialei Li Gang Zou WeiWei Shang Jun Jiang Yi Luo 2022National Science Review2022,9,10:5
7Phosphate removal by a La(OH)_(3) loaded magnetic MAPTAC-based cationic hydrogel:Enhanced surface charge density and Donnan membrane effect显示文摘Cationic hydrogels have received great attention to control eutrophication and recycle phosphate.In this study,a type of La(OH)_(3) loaded magnetic MAPTAC-based cationic hydrogel(La(OH)_(3)@MMCH)was developed as a potential adsorbent for enhanced phosphate removal from aqueous environment.La(OH)_(3)@MMCH exhibited high adsorption capacity of 105.72±5.99 mg P/g,and reached equilibrium within 2 hr.La(OH)_(3)@MMCH could perform effectively in a wide pH range from 3.0 to 9.0 and in the presence of coexisting ions(including SO_(4)^(2-),Cl^(-),NO_(3)^(-),HCO_(3)^(-),SiO_(4)^(4-) and HA).The adsorption-desorption experiment indicated that La(OH)_(3)@MMCH could be easily regenerated by using NaOH-NaCl as the desorption agent,and 73.3%adsorption capacity remained after five cycles.Moreover,La(OH)_(3)@MMCH was employed to treat surface water with phosphate concentration of 1.90 mg/L and showed great removal efficiency of 95.21%.Actually,MMCH showed high surface charge density of 34.38-59.38 meq/kg in the pH range from 3.0 to 11.0 and great swelling ratio of 3014.57%within 24 h,indicating that MMCH could produce the enhanced Donnan membrane effect to pre-permeate phosphate.Furthermore,the bifunctional structure of La(OH)_(3)@MMCH enabled it to capture phosphate through electrostatic attraction and ligand exchange.All the results prove that La(OH)_(3)@MMCH is a promising adsorbent for eutrophication control and phosphate recovery.Yanqing Zhou Yili Wang Shuoxun Dong Haotian Hao Junyi Li Chenyang Liu Xiaolin Li Yao Tong 2022Journal of Environmental Sciences2022,34,3:4
8STUDY ON ELECTRORHEOLOGICAL FLUID DAMPER FOR APPLICATION IN MACHINING CHATTER CONTROL显示文摘The electrorheological fluid(ERF)is a kind of intelligent material with bright prospects for industry applications, which has viscoelastic characteristic under the applied electric field. The dynamic model of a milling system with an ERF damper is established, and the chatter suppression mechanism of the ER effect is discussed theoretically. Both the theoretical study and the experimental investigation show that the additional damping and additional stiffness produced by the ERF increase with the rise in the strength of electric field E, but their influence on the cutting stability is different. Only when both additional damping and additional stiffness cooperate, the milling chatter can be suppressed quickly and effectively. In additional, an ERF damper used on the arbor of horizontal spindle milling machine is developed, and a series of milling chatter control experiments are performed. The experimental results show that the milling chatter can be suppressed effectively by using the ER damper.Yu Junyi Zhang YongliangWang Maohua Zhou XiaoqinFaculty of Mechanical Scienceand Engineering,Jilin University,Changchun 130025, China 2003Chinese Journal of Mechanical Engineering2003,16,1:4
9Mixed lymphocyte reaction induced by multiple alloantigens and the role for IL-10 in proliferation inhibition显示文摘The frequency of T cells that can respond to alloantigens is unusually high.It remains unclear how T cells would respond when stimulated by multiple major histocompatibility complex(MHC)disparate alloantigens in the same cultures.In this report,we examined potential interactions of T cell clones that were stimulated simultaneously by two sets of complete MHC disparate alloantigens using mixed lymphocyte reaction(MLR).In this assay,we observed that proliferation of B6 lymphocytes(H-2b)stimulated by both BALB/c(H-2d)and C_(3)H(H-2k)allogeneic cells was not increased but rather reduced as compared to B6 cells stimulated with either BALB/c or C_(3)H allogeneic cells.Interestingly,interleukin(IL)-10 expressions at both protein level and mRNA level was signifi cantly increased in cultures stimulated with the two MHC alloantigens,while IL-2,tumor necrosis factor(TNF)-α,transforming growth factor(TGF)-β1 production did not show any differences.In addition,Foxp_(3) mRNA expression was comparable amongst all groups.In conclusion,we observed an inhibitory effect in T cell proliferation in response to multiple MHC mismatched alloantigens in MLR,and this effect might be associated with the upregulation of IL-10 expression.Junyi Zhou Weifeng He Gaoxing Luo Jun Wu 2014Burns & Trauma2014,2,1:2
10Simultaneous diffusion of cation and anion to access N,S cocoordinated Bi-sites for enhanced CO_(2) electroreduction显示文摘Developing highly active single-atom sites catalysts for electrochemical reduction of CO_(2) is an effective and environmental-friendly strategy to promote carbon-neutral energy cycle and ameliorate global climate issues.Herein,we develop an atomically dispersed N,S co-coordinated bismuth atom sites catalyst(Bi-SAs-NS/C)via a cation and anion simultaneous diffusion strategy for electrocatalytic CO_(2) reduction.In this strategy,the bonded Bi cation and S anion are simultaneously diffused into the nitrogen-doped carbon layer in the form of Bi2S3.Then Bi is captured by the abundant N-rich vacancies and S is bonded with carbons.support at high temperature,formed the N,S co-coordinated Bi sites.Benefiting from the simultaneous diffusion of Bi and S,different electronegative N and S can be effectively co-coordinated with Bi,forming the uniform Bi-N_(3)S/C sites.The synthesized.Bi-SAs-NS/C exhibits a high selectivity towards CO with over 88%Faradaic efficiency in a wide potential range,and achieves a maximum FE_(CO)of 98.3%at-0.8 V vs.RHE with a current density of 10.24 mA·cm^(-2),which can keep constant with negligible degradation in 24 h continuous electrolysis.Experimental results and theoretical calculations reveal that the significantly improved catalytic performance of Bi-SAs-NS/C than Bi-SAs-N/C is ascribed to the replacement of one coordinated-N with low electronegative S in Bi-N_(4)C center,which can greatly reduce the energy barrier of the intermediate formation in rate-limiting step and increase the reaction kinetics.This work provides an effective strategy for rationally designing highly active single-atom sites;catalysts for efficient electrocatalysis with optimized electronic structure.Zhiyuan Wang Chun Wang Yidong Hu Shuai Yang Jia Yang Wenxing Chen Huang Zhou Fangyao Zhou Lingxiao Wang Junyi Du Yafei Li Yuen Wu 2021Nano Research2021,14,8:2
11Cytoplasmic and nuclear genome variations of rice hybrids and their parents inform the trajectory and strategy of hybrid rice breeding显示文摘The male sterility(MS)line is a prerequisite for efficient production of hybrid seeds in rice,a self-pollinating species.MS line breeding is pivotal for hybrid rice improvement.Understanding the historical breeding tra-jectory will help to improve hybrid rice breeding strategies.Maternally inherited cytoplasm is an appro-priate tool for phylogenetic reconstruction and pedigree tracing in rice hybrids.In this study,we analyzed the cytoplasmic genomes of 1495 elite hybrid rice varieties and identified five major types of cytoplasm,which correspond to different hybrid production systems.As the cytoplasm donors for hybrids,461 MS lines were also divided into five major types based on cytoplasmic and nuclear genomic architecture.Spe-cific core accessions cooperating with different fertility-associated genes drove the sequence divergence of MS lines.Dozens to hundreds of convergent and divergent selective sweeps spanning several agro-nomic trait-associated genes were identified among different types of MS lines.We further analyzed the cross patterns between different types of MS lines and their corresponding restorers.This study system-atically analyzed the cytoplasmic genomes of rice hybrids revealed their relationships with nuclear ge-nomes of MS lines,and illustrated the trajectory of hybrid rice breeding and the strategies for breeding different types of MS lines providing new insights for future improvement of hybrid rice.Zhoulin Gu Zhou Zhu Zhen Li Qilin Zhan Qi Feng Congcong Zhou Qiang Zhao Yan Zhao Xiaojian Peng Bingxin Dai Rongrong Sun Yan Li Hengyun Lu Lei Zhang Tao Huang Junyi Gong Danfeng Lv Xuehui Huang Bin Han 2021Molecular Plant2021,14,12:2
12The cruise observation of turbulent mixing in the upwelling region east of Hainan Island in the summer of 2012显示文摘The turbulent mixing in the upwelling region east of Hainan Island in the South China Sea is analyzed based on in situ microstructure observations made in July 2012. During the observation, strong upwelling appears in the coastal waters, which are 3℃ cooler than the offshore waters and have a salinity 1.0 greater than that of the offshore waters. The magnitude of the dissipation rate of turbulent kinetic energy ε in the upwelling region is O(10–9 W/kg), which is comparable to the general oceanic dissipation. The inferred eddy diffusivity K_ρ is O(10–6 m^2/s), which is one order of magnitude lower than that in the open ocean. The values are elevated to K_ρ≈O(10–4 m^2/s) near the boundaries. Weak mixing in the upwelling region is consistent with weak instability as a result of moderate shears versus strong stratifications by the joint influence of surface heating and upwelling of cold water.The validity of two fine-scale structure mixing parameterization models are tested by comparison with the observed dissipation rates. The results indicate that the model developed by Mac Kinnon and Gregg in 2003 provides relatively better estimates with magnitudes close to the observations. Mixing parameterization models need to be further improved in the coastal upwelling region.LI Mingming XIE Lingling ZONG Xiaolong ZHANG Shuwen ZHOU Lei LI Junyi 2018Acta Oceanologica Sinica2018,37,9:2

14Highly efficient P uptake by Fe3O4 loaded amorphous Zr-La (carbonate) oxides: Electrostatic attraction, inner-sphere complexation and oxygen vacancies acceleration effect显示文摘Bimetallic oxides composites have received an increasing attention as promising adsorbents for aqueous phosphate (P) removal in recent years. In this study, a novel magnetic composite MZLCO was prepared by hybridizing amorphous Zr-La (carbonate) oxides (ZLCO) with nano-FeOthrough a one-pot solvothermal method for efficient phosphate adsorption. Our optimum sample of MZLCO-45 exhibited a high Langmuir maximum adsorption capacity of 96.16 mg P/g and performed well even at low phosphate concentration. The phosphate adsorption kinetics by MZLCO-45 fitted well with the pseudo-second-order model, and the adsorption capacity could reach 79% of the ultimate value within the first 60 min. The phosphate adsorption process was highly p H-dependent, and MZLCO-45 performed well over a wide p H range of 2.0-8.0. Moreover, MZLCO-45 showed a strong selectivity to phosphate in the presence of competing ions (Cl^(-), NO_(3)^(-), SO_(4)^(2-), HCO_(3)^(-), Ca^(2+), and Mg^(2+)) and a good reusability using the eluent of Na OH/Na Cl mixture, then 64% adsorption capacity remained after ten recycles. The initial 2.0 mg P/L in municipal wastewater and surface water could be efficiently reduced to below 0.1mg P/L by 0.07 g/L MZLCO-45, and the phosphate removal efficiencies were 95.7% and 96.21%, respectively. Phosphate adsorption mechanisms by MZLCO-45 could be attributed to electrostatic attraction and the inner-sphere complexation via ligand exchange forming Zr/La-O-P, -OH and CO_(3)^(2-)groups on MZLCO-45 surface played important roles in the ligand exchange process. The existence of oxygen vacancies could accelerate the phosphate absorption rate of the MZLCO-45 composites.Chenyang Liu Yili Wang Xiaolin Li Junyi Li Shuoxun Dong Haotian Hao Yao Tong Yanqing Zhou 2022Journal of Environmental Sciences2022,34,10:2
15Social insights on the implementation of One Health in zoonosis prevention and control: a scoping review显示文摘Background:The One Health (OH) concept has been promoted widely around the globe. OH framework is expected to be applied as an integrated approach to support addressing zoonotic diseases as a significant global health issue and to improve the efficiency and effectiveness of zoonosis prevention and control. This review is intended to overview the social impact of the implementation of OH on zoonosis prevention and control.Methods:A scoping review of studies in the past 10 years was performed to overview the integration feature of OH in zoonosis prevention and control and the social impacts of OH. PubMed and Web of Science were searched for studies published in English between January 2011 and June 2021. The included studies were selected based on predefined criteria.Results:Thirty-two studies were included in this review, and most of them adopted qualitative and semi-qualitative methods. More than 50% of the studies focused on zoonosis prevention and control. Most studies were conducted in low- and middle-income countries in Africa and Asia. Applying OH approach in diseases control integrates policymakers, stakeholders, and academics from various backgrounds. The impact of OH on economic is estimated that it may alleviate the burden of diseases and poverty in the long term, even though more financial support might be needed at the initial stage of OH implementation. OH implementation considers social and ecological factors related to zoonosis transmission and provides comprehensive strategies to assess and address related risks in different communities according to regions and customs.Conclusions:Based on reviewed literature, although there seems to be a lack of guidelines for assessing and visualizing the outcomes of OH implementation, which may limit the large-scale adoption of it, evidence on the contributions of implementing OH concepts on zoonosis prevention and control indicates long-term benefits to society, including a better integration of politics, stakeholders and academics to improve their cooperation, a potential to address economic issues caused by zoonosis, and a comprehensive consideration on social determinants of health during zoonosis prevention and control.Junyi He Zhaoyu Guo Pin Yang Chunli Cao Jing Xu Xiaonong Zhou Shizhu Li 2022Infectious Diseases of Poverty2022,11,3:1
