| 1 | Interaction between PCC Filler and Cellulosic Fiber in Fiber/Filler Co-refining System显示文摘Mineral fillers are important for conserving raw fiber materials and reducing production costs in the paper industry.However,the increase in filler content will inevitably result in strength reduction,which limits the adding amount of filler in paper production.In this study,we designed a cellulose fiber/filler co-refining approach to improve the strength and optical properties of paper;moreover,the synergistic interaction between fibers and precipitated calcium carbonate(PCC)fillers in the co-refining process was investigated.Results of fiber separation and PCC particle size analysis showed that,compared with conventional refining,the content of fines increased,whereas the PCC particle size decreased.More importantly,composites were formed between the PCC and fines,which promoted strength improvement of paper.Physical tests show that the tensile index of paper with 15%PCC content increased by 22%compared with that of the paper filled by conventional method,whereas the brightness and opacity of paper improved by fiber/filler co-refining for a specified filler content.These findings provide a basis for the further development of co-refining filling technology. | Sheng Qiang Shunxi Song Peiyao Wang Yujie Shi Linhao Li Haitang Liu | 2021 | Paper And Biomaterials2021，6，4： | 5 |
| 2 | Myristica fragrans promotes ABCA1 expression and cholesterol efflux in THP-1-derived macrophages显示文摘Myristica fragrans is a traditional herbal medicine and has been shown to alleviate the development of atherosclerosis.However,the anti-atherogenic mechanisms of M.fragrans are still to be addressed.In this study,we explored the effect of M.fragrans on lipid metabolism and inflammation and its mechanisms in THP-1-derived macrophages.The quantitative polymerase chain reaction and western blot analysis results showed that M.fragrans promotes cholesterol efflux from THP-1-derived macrophages and reduces intracellular total cholesterol,cholesterol ester,and free cholesterol contents in a dose-and a time-dependent manner.Further study found that liver X receptor alpha(LXRα)antagonist GGPP significantly blocked the upregulation of ABCA1 expression with M.fragrans treatment.In addition,chromatin immunoprecipitation assay confirmed that GATA binding protein 3(GATA3)can bind to the LXRαpromoter,and inhibition of GATA3 led to the downregulation of LXRαand ATP-binding cassette subfamily A member 1 expression.Furthermore,M.fragrans reduced lipid accumulation,followed by decreasing tumor necrosis factor-α,interleukin(IL)-6,and IL-1βand increasing IL-10 produced by THP-1-derived macrophages.Therefore,M.fragrans is identified as a valuable therapeutic medicine for atherosclerotic cardiovascular disease. | Shangming Liu Jiahui Gao Linhao He Zhenwang Zhao Gang Wang Jin Zou Li Zhou Xiangjun Wan Shilin Tang Chaoke Tang | 2021 | Acta Biochimica et Biophysica Sinica2021，53，1： | 2 |

| 5 | χ(^(2)) nonlinear photonics in integrated microresonators显示文摘Second-order(χ^((2))) optical nonlinearity is one of the most common mechanisms for modulating and generating coherent light in photonic devices.Due to strong photon confnement and long photon lifetime,integrated microresonators have emerged as an ideal platform for investigation of nonlinear optical efects.However,existing silicon-based materials lack a χ^((2)) response due to their centrosymmetric structures.A variety of novel material platforms possessing χ^((2)) nonlinearity have been developed over the past two decades.This review comprehensively summarizes the progress of second-order nonlinear optical efects in integrated microresonators.First,the basic principles of χ^((2)) nonlinear efects are introduced.Afterward,we highlight the commonly used χ^((2)) nonlinear optical materials,including their material properties and respective functional devices.We also discuss the prospects and challenges of utilizing χ^((2)) nonlinearity in the feld of integrated microcavity photonics. | Pengfei Liu Hao Wen Linhao Ren Lei Shi Xinliang Zhang | 2023 | Frontiers of Optoelectronics2023，16，3： | 0 |

| 7 | Multi-functionalized nanofibers with reactive oxygen species scavenging capability and fibrocartilage inductivity for tendon-bone integration显示文摘The presence of excessive reactive oxygen species(ROS)after injuries to the enthesis could lead to cellular oxidative damage,high inflammatory response,chronic inflammation,and limited fibrochondral inductivity,making tissue repair and functional recovery difficult.Here,a multifunctional silk fibroin nanofiber modified with polydopamine and kartogenin was designed and fabricated to not only effectively reduce inflammation by scavenging ROS in the early stage of the enthesis healing but also enhance fibrocartilage formation with fibrochondrogenic induction in the later stages.The in vitro results confirmed the antioxidant capability and the fibrochondral inductivity of the functionalized nanofibers.In vivo studies showed that the multifunctional nanofiber can significantly improve the integration of tendon-bone and accelerate the regeneration of interface tissue,resulting in an excellent biomechanical property.Thus,the incorporation of antioxidant and bio-active molecules into extracellular matrix-like biomaterials in interface tissue engineering provides an integrative approach that facilitates damaged tissue regeneration and functional recovery,thereby improving the clinical outcome of the engineered tissue. | Peixing Chen Sixiang Wang Zhi Huang Yan Gao Yu Zhang Chunli Wang Tingting Xia Linhao Li Wanqian Liu Li Yang | 2021 | Journal of Materials Science & Technology2021，，11： | 0 |

| 9 | Differences in root stress and strain distribution in buccal and lingual orthodontics: A finite element analysis study显示文摘Orthodontic forces can cause stress and strain concentration and microcracks on tooth root surfaces.This study aimed to analyze whether a lingual orthodontic appliance was more likely to cause root stress concentration and root resorption than the traditional buccal appliance.A finite element model of the root of the maxillary central incisor with straight,buccal,and lingual curvatures was established.A load perpendicular to the tooth surface on the buccal and lingual surfaces of the central incisor was applied,and the stress and strain concentration at the root apex was compared.The stress and strain at the root apex of the lingual cingulum group were lesser than those of the buccal group;little difference was observed between the lingual and buccal clinical crown central augmentation groups.The stress and strain at the root apex of the lingual direction movement group were greater than those of the buccal direction movement group.The direction of the root curvature also influenced the amount of stress and strain at the root apex.The difference in the risk of root resorption between lingual and buccal orthodontics is dependent on the height of the bracket placement.The loading direction of the orthodontic force and direction of the root curvature also affect the stress and strain at the root apex. | Shengzhao Xiao Xiangfei Kong Jie Yao Jinlin Liu Linhao Li Tianyun Jiang Lizhen Wang Yubo Fan | 2022 | Medicine in Novel Technology and Devices2022，，2： | 0 |
| 10 | CH02 peptide promotes ex vivo expansion of umbilical cord blood-derived CD34+hematopoietic stem/progenitor cells显示文摘Umbilical cord blood(UCB)is an advantageous source for hematopoietic stem/progenitor cell(HSPC)transplantation,yet the current strategies for large-scale and cost-effective UCB-HSPC preparation are still unavailable.To overcome these obstacles,we systematically evaluate the feasibility of our newly identified CH02 peptide for ex vivo expansion of CD34^(+)UCB-HSPCs.We herein report that the CH02 peptide is specifically enriched in HSPC proliferation via activating the FLT3 signaling.Notably,the CH02-based cocktails are adequate for boosting 12-fold ex vivo expansion of UCB-HSPCs.Meanwhile,CH02-preconditioned UCB-HSPCs manifest preferable efficacy upon wound healing in diabetic mice via bidirectional orchestration of proinflammatory and anti-inflammatory factors.Together,our data indicate the advantages of the CH02-based strategy for ex vivo expansion of CD34^(+)UCB-HSPCs,which will provide new strategies for further development of large-scale HSPC preparation for clinical purposes. | Yiqi Yang Bihui Zhang Junye Xie Jingsheng Li Jia Liu Rongzhan Liu Linhao Zhang Jinting Zhang Zijian Su Fu Li Leisheng Zhang An Hong Xiaojia Chen | 2023 | Acta Biochimica et Biophysica Sinica2023，55，10： | 0 |
