| 2 | Construction of heparin-based hydrogel incorporated with Cu_(5.4)O ultrasmall nanozymes for wound healing and inflammation inhibition显示文摘Excessive production of inflammatory chemokines and reactive oxygen species(ROS)can cause a feedback cycle of inflammation response that has a negative effect on cutaneous wound healing.The use of wound-dressing materials that simultaneously absorb chemokines and scavenge ROS constitutes a novel‘weeding and uprooting’treatment strategy for inflammatory conditions.In the present study,a composite hydrogel comprising an amine-functionalized star-shaped polyethylene glycol(starPEG)and heparin for chemokine sequestration as well as Cu_(5.4)O ultrasmall nanozymes for ROS scavenging(Cu_(5.4)O@Hep-PEG)was developed.The material effectively adsorbs the inflammatory chemokines monocyte chemoattractant protein-1 and interleukin-8,decreasing the migratory activity of macrophages and neutrophils.Furthermore,it scavenges the ROS in wound fluids to mitigate oxidative stress,and the sustained release of Cu_(5.4)O promotes angiogenesis.In acute wounds and impaired-healing wounds(diabetic wounds),Cu_(5.4)O@Hep-PEG hydrogels outperform the standard-of-care product Promogram®in terms of inflammation reduction,increased epidermis regeneration,vascularization,and wound closure. | Yuan Peng Danfeng He Xin Ge Yifei Lu Yuanhao Chai Yixin Zhang Zhengwei Mao Gaoxing Luo Jun Deng Yan Zhang | 2021 | Bioactive Materials2021,6,10: | 7 |
| 3 | The modified bilobed flap for reconstructing sacral decubitus ulcers显示文摘Background:Sacral pressure ulcers are associated with high morbidity and,in some cases,result in mortality from severe sepsis.Local flaps are frequently used for reconstruction of stage III and IV pressure ulcers.An ideal flap should be simple to design,have a reliable vascular supply and minimal donor site morbidity.Our study evaluates the use of a bilobed flap based on the superficial branch of the superior gluteal artery or the posterior branch of the fourth lumbar artery to reconstruct the sacral pressure ulcer.Case presentation:We performed a retrospective analysis of paraplegic patients with sacral pressure ulcers treated with our bilobed flaps from January 2015 to December 2019.A description of our management,operative protocol,outcome and complications is outlined.Seven paraplegic patients(6 male,1 female;average age 53.1 years)with sacral pressure ulcers were treated with our bilobed flap based on the superficial branch of the superior gluteal artery or the posterior branch of the fourth lumbar artery.The average size of the pressure ulcers was 7×5 cm(range 6.2×4.5 cm to 11×10 cm).All 7 flaps survived.The patients were followed up for 12 months without significant complications,such as flap necrosis or recurrence.Conclusions:The superficial branch of the superior gluteal artery or the posterior branch of the fourth lumbar artery reliably supplies the bilobed flap.The superior cluneal nerve can be included in the design.The technique is simple and reliable.It should be included in the reconstructive algorithm for the management of sacral pressure ulcers. | Xiangong Jiao Chunxiao Cui Sally Kiu-Huen Ng Zhangjia Jiang Chihui Tu Jiemin Zhou Xiandong Lu Xianwen Ouyang Tong Luo Ke Li Yixin Zhang | 2020 | Burns & Trauma2020,8,1: | 4 |
| 4 | β-catenin activation in hair follicle dermal stem cells in duces ectopic hair outgrowth and skin fibrosis显示文摘Hair follicle dermal sheath(DS)harbors hair follicle dermal stem cells(hfDSCs),which can be recruited to replenish DS and dermal papilla(DP).Cultured DS cells can differentiate into various cell lineages in vitro.However,it is unclear how its plasticity is modulated in vivo.Wnt/β-catenin signaling plays an important role in maintaining stem cells of various lineages and is required for HF development and regeneration.Here we report that activation ofβ-catenin in DS generates ectopic HF outgrowth(EF)by reprogramming HF epidermal cells and DS cells themselves,and endows DS cells with hair inducing ability.Epidermal homeostasis of pre-existing HFs is disrupted.Additionally,cell-autonomous progressive skin fibrosis is prominent in dermis,where the excessive fibroblasts largely originate from DS.Gene expression analysis of purified DS cells with activatedβ-catenin revealed significantly increased expression of Bmp,Fgf,and Notch ligands and administration of Bmp,Fgf,or Notch signaling inhibitor attenuates EF formation.In summary,our findings advance the current knowledge of high plasticity of DS cells and provide an insight into understanding how Wnt/β-catenin signaling controls DS cell behaviors. | Yixin Tao Qingchun Yang Lei Wang Jie Zhang Xuming Zhu Qianqian Sun Yunbin Han Qian Luo Yushu Wang Xizhi Guo Ji Wu Baojie Li Xiao Yang Lin He Gang Ma | 2019 | Journal of Molecular Cell Biology2019,11,1: | 4 |

| 6 | Monte Carlo simulations of the sensor head of imaging energetic electron spectrometer onboard a Chinese IGSO navigation satellite显示文摘An imaging energetic electron spectrometer built by the Peking University team(BD-IES) onboard a Chinese navigation satellite in an inclined GEO orbit has been launched successfully in September 2015, which measures the spectra of the energetic electrons with the energy range of 50–600 keV in nine directions. In this study, Monte Carlo simulations of the BD-IES sensor head were performed using Geant4 and the corresponding characteristic responses to the isotropic energetic particles were derived. The effective geometric factors were estimated using the typical electron and proton spectra in the GEO orbit and the corresponding simulated sensor head responses. It was found that the average effective geometric factors of nine directions are close to the nominal geometric factors calculated with the traditional method, but the effective geometric factor decreases as the center energy of the energy channel decreases. The BD-IES sensor head also responses to the energetic protons, but the average contamination rate of all 72 channels is about 2%, which means that the proton contamination is acceptable. The spectra of the energetic electrons measured by BD-IES are derived using the effective geometric factors of the sensor head and are comparable with the spectra measured by the magnetic electron ion spectrometer(MagEIS) instrument onboard Van Allen Probes. | ZOU Hong YE YuGuang ZONG QiuGang CHEN HongFei LUO Lin ZHOU XuZhi CHEN XingRan HAO YiXin REN Jie WANG YongFu SHI WeiHong YU XiangQian JIA XiangHong XU Feng ZHANG XiaoXin | 2019 | Science China(Technological Sciences)2019,62,7: | 3 |
| 7 | CsPb(I_(x)Br_(1-x))_(3) solar cells显示文摘Owing to its nice performance, low cost, and simple solution-processing, organic-inorganic hybrid perovskite solar cell(PSC) becomes a promising candidate for next-generation high-efficiency solar cells.The power conversion efficiency(PCE) has boosted from 3.8% to 25.2% over the past ten years. Despite the rapid progress in PCE, the device stability is a key issue that impedes the commercialization of PSCs. Recently, all-inorganic cesium lead halide perovskites have attracted much attention due to their better stability compared with their organic-inorganic counterpart. In this progress report, we summarize the properties of CsPb(IxBr1-x)3 and their applications in solar cells. The current challenges and corresponding solutions are discussed. Finally, we share our perspectives on CsPb(IxBr1-x)3 solar cells and outline possible directions to further improve the device performance. | Xue Jia Chuantian Zuo Shuxia Tao Kuan Sun Yixin Zhao Shangfeng Yang Ming Cheng Mingkui Wang Yongbo Yuan Junliang Yang Feng Gao Guichuan Xing Zhanhua Wei Lijun Zhang Hin-Lap Yip Mingzhen Liu Qing Shen Longwei Yin Liyuan Han Shengzhong Liu Lianzhou Wang Jingshan Luo Hairen Tan Zhiwen Jin Liming Ding | 2019 | Science Bulletin2019,64,20: | 2 |
| 8 | Prediction of a common neutralizing epitope of H5N1 avian influenza virus by in silico molecular docking显示文摘The H5N1 avian influenza virus (AIV) has widely spread in Asia, Europe and Africa, making a large amount of economic loss. Recently, our research group has screened a common neutralizing mono- clonal antibody named 8H5, which can neutralize almost all H5 subtype AIV ever isolated so far. Obvi- ously, this monoclonal antibody would benefit for research and development of the universal AIV vac- cine and design of the drug against H5N1 AIV in high mutation rate. In this study, the homology mod- eling was applied to generate the 3D structure of 8H5 Fab fragment, and 'canonical structure' method was used to define the specified loop conformation of CDR regions. The model was subjected to en- ergy minimization in cvff force field with Discovery module in Insight II program. The resulting model has correct stereochemistry as gauged from the Ramachandran plot calculation and good 3D-structure compatibility as assessed by interaction energy analysis, solvent accessible surface (SAS) analysis, and Profiles-3D approach. Furthermore, the 8H5 Fab model was subjected to docking with three H5 subtype hemagglutinin (HA) structures deposited in PDB (ID No: 1jsm, 2ibx and 2fk0) respectively. The result indicates that the three docked complexes share a common binding interface, but differ in bind- ing angle related with HA structure similarity between viral subtypes. In the light of the three HA inter- faces with structural homology analysis, the common neutralizing epitope on HA recognized by 8H5 consists of 9 incontinuous amino acid residues: Asp68, Asn72, Glu112, Lys113, Ile114, Pro118, Ser120, Tyr137, Tyr252 (numbered as for 1jsm sequence). The primary purpose of the present work is to provide some insight into structure and binding details of a common neutralizing epitope of H5N1 AIV, thereby aiding in the structure-based design of universal AIV vaccines and anti-virus therapeutic drugs. | YAN YuanQing LI ShaoWei YANG ChunYan LUO WenXin WANG MingQiao CHEN YiXin LUO HaiFeng wu Ting ZHANG Jun XIA NingShao | 2008 | Chinese Science Bulletin2008,53,6: | 2 |

| 10 | New Algorithm Rules Out Acute-on-chronic Liver Failure Development within 28 Days from Acute Decompensation of Cirrhosis显示文摘Background and Aims:Approximately 10%of patients with acute decompensated(AD)cirrhosis develop acute-on-chronic liver failure(ACLF)within 28 days.Such cases have high mortality and are difficult to predict.Therefore,we aimed to establish and validate an algorithm to identify these patients on hospitalization.Methods:Hospitalized patients with AD who developed ACLF within 28 days were considered pre-ACLF.Organ dysfunction was defined accord-ing to the chronic liver failure-sequential organ failure as-sessment(CLIF-SOFA)criteria,and proven bacterial infec-tion was taken to indicate immune system dysfunction.A retrospective multicenter cohort and prospective one were used to derive and to validate the potential algorithm,re-spectively.A miss rate of<5%was acceptable for the calcu-lating algorithm to rule out pre-ACLF.Results:In the deri-vation cohort(n=673),46 patients developed ACLF within 28 days.Serum total bilirubin,creatinine,international normalized ratio,and present proven bacterial infection at admission were associated with the development of ACLF.AD patients with≥2 organ dysfunctions had a higher risk for pre-ACLF patients[odds ratio=16.58195%confidence interval:(4.271-64.363),p<0.001].In the derivation co-hort,67.5%of patients(454/673)had≤1 organ dysfunction and two patients(0.4%)were pre-ACLF,with a miss rate of 4.3%(missed/total,2/46).In the validation cohort,65.9%of patients(914/1388)had≤1 organ dysfunction,and four(0.3%)of them were pre-ACLF,with a miss rate of 3.4%(missed/total,4/117).Conclusions:AD patients with≤1 organ dysfunction had a significantly lower risk of developing ACLF within 28 days of admission and could be safely ruled out with a pre-ACLF miss rate of<5%. | Xiaoting Tang Hai Li Guohong Deng Xin Zheng Xianbo Wang Yan Huang Yanhang Gao Zhongji Meng Zhiping Qian Feng Liu Xiaobo Lu Yu Shi Beiling Li Wenyi Gu Xiaomei Xiang Yan Xiong Yixin Hou Jun Chen Na Gao Sen Luo Liujuan Ji Jing Li Rongjiong Zheng Haotang Ren Jinjun Chen | 2023 | Journal of Clinical and Translational Hepatology2023,11,3: | 1 |

| 12 | Fluorescence characterization and microbial degradation of dissolved organic matter leached from salt marsh plants in the Yellow River Delta显示文摘盐沼植被是沿海水体中溶解有机物(Dissolved Organic Matter,DOM)的重要贡献者。然而,不同盐沼植物释放DOM的动力学特征尚缺乏系统研究和比较。黄河三角洲湿地是中国东海岸面积最大,保护最完善的沿海生态系统之一。本论文研究了2016年10月从黄河三角洲(Yellow River Delta,YRD)盐沼中采集的三种常见沼泽植物(芦苇(Phragmites australis),碱蓬(Suaeda salsa)和獐茅(Aeluropus littoralis)的DOM释放过程。通过测定溶解有机碳(Dissolved Organic Carbon,DOC)和溶解氮(Dissolved Nitrogen,DN)发现,植物叶片释放的DOM浓度远高于其根和茎。在27天的培养期内,平均有15%的生物碳和30%的生物氮以DOC和DN的形式通过植物叶片释放。从植物中释放的DOM非常不稳定,在27天的培养期内,细菌共消耗了92.4%-98.1%的DOC和88.0%-94.6%的DN。植物释放DOM的荧光特性表明,发色溶解的有机物(Chromophoric Dissolved Organic Matter,CDOM)是DOM的主要组分,而类蛋白组分是植物释放CDOM的主要组分。细菌的降解作用改变了DOM的荧光性质和化学组成。上述的室内研究结果得到了实地调查的充分支撑,表明在深秋时期黄河口湿地有大量DOM溢出。本研究结果表明,盐沼植物释放的DOM是沼泽和沿海水域DOC和DN的重要来源,而且易降解DOC和DN为黄河口湿地和邻近沿海水域中的微生物群落提供了重要的食物来源。 | Tao Zhang Zhihua Feng Chunle Luo Yixin Sun Jinzhen Li Juntian Xu Xuchen Wang | 2020 | Journal of Plant Ecology2020,13,5: | 1 |

| 14 | Compression Algorithm for Implicit 3D B-Spline Solids显示文摘Due to advantages in solid modeling with complex geometry and its ideal suitability for 3D printing,the implicit representation has been widely used in recent years.The demand for free-form shapes makes the implicit tensor-product B-spline representation attract more and more attention.However,it is an important challenge to deal with the storage and transmission requirements of enormous coefficient ten-sor.In this paper,we propose a new compression framework for coefficient tensors of implicit 3D tensor-product B-spline solids.The proposed compression algorithm consists of four steps,i.e.,preprocessing,block splitting,using a lifting-based 3D discrete wavelet transform,and coding with 3D set partitioning in hierarchical trees algorithm.Finally,we manage to lessen the criticism of the implicit tensor-product B-spline representation of surface for its redundancy store of 3D coefficient tensor.Experimental results show that the proposed compression framework not only achieves satisfactory reconstruction quality and considerable compression ratios,but also sup-ports progressive transmissions and random access by employing patch-wise coding strategy. | Yanzhi Song Yixin Luo Yuan Liu Jiansong Deng Zhouwang Yang | 2018 | Communications in Mathematics and Statistics2018,6,2: | 1 |

| 16 | In vivo inducing collagen regeneration of biodegradable polymer microspheres显示文摘Biodegradable polymer particles have been used as dermal fillers for pre-clinical and clinical trials.The impact of material properties of polymers is very important to develop products for aesthetic medicine such as dermal fillers.Herein,eight biodegradable polymers with different molecular weights,chemical compositions or hydrophilic-hydrophobic properties were prepared and characterized for systematical study for aesthetic medicine applications.Polymer microspheres with 20-100 lmwere prepared.The in vitro degradation study showed that poly(L-lactic-co-glycolic acid)75/25 microspheres degraded the fastest,whereas poly(L-lactic acid)(PLLA)microspheres with intrinsic viscosity of 6.89([g]¼6.89)with the highest molecular weight showed the slowest degradation rate.After these microspheres were fabricated dermal fillers according to the formula of SculptraVR,they were injected subcutaneously into the back skin of rabbits.In vivo results demonstrated that the degradation rate of microspheres strongly correlated with the foreign body reaction and collagen regeneration was induced by microspheres.The microspheres with faster degradation rate induced inflammatory response and the collagen regeneration maintained in shorter time.PLLA([g]¼3.80)microsphere with a moderate molecular weight and degradation rate could strongly regenerate Type I and III collagen to maintain a long-term aesthetic medicine effect.These properties of size,morphology and degradation behavior would influence the foreign body reaction and collagen regeneration. | Yixin Zhang Hanwen Liang Qian Luo Jianlin Chen Nan Zhao Wenxia Gao Yuji Pu Bin He Jing Xie | 2021 | Regenerative Biomaterials2021,8,5: | 1 |
