| 1 | Progress of the key materials for organic solar cells显示文摘Organic solar cells have attracted academic and industrial interests due to the advantages like lightweight,flexibility and roll-to-roll fabrication.Nowadays,18%power conversion efficiency has been achieved in the state-of-the-art organic solar cells.The recent rapid progress in organic solar cells relies on the continuously emerging new materials and device fabrication technologies,and the deep understanding on film morphology,molecular packing and device physics.Donor and acceptor materials are the key materials for organic solar cells since they determine the device performance.The past 25 years have witnessed an odyssey in developing high-performance donors and acceptors.In this review,we focus on those star materials and milestone work,and introduce the molecular structure evolution of key materials.These key materials include homopolymer donors,D-A copolymer donors,A-D-A small molecular donors,fullerene acceptors and nonfullerene acceptors.At last,we outlook the challenges and very important directions in key materials development. | Yang Tong Zuo Xiao Xiaoyan Du Chuantian Zuo Yuelong Li Menglan Lv Yongbo Yuan Chenyi Yi Feng Hao Yong Hua Ting Lei Qianqian Lin Kuan Sun Dewei Zhao Chunhui Duan Xiangfeng Shao Wei Li Hin-Lap Yip Zhengguo Xiaol Bin Zhang Qingzhen Bian Yuanhang Cheng Shengjian Liu Ming Cheng Zhiwen Jin Shangfeng Yang Liming Ding | 2020 | Science China Chemistry2020，63，6： | 15 |
| 2 | Bisphosphonate-based nanocomposite hydrogels for biomedical applications显示文摘Nanocomposite hydrogels consist of polymeric network embedded with functional nanoparticles or nanostructures,which not only contribute to the enhanced mechanical properties but also exhibit the bioactivities for regulating cell behavior.Bisphosphonates(BPs)are capable of coordinating with various metal ions and modulating bone homeostasis.Thanks to the inherent dynamic properties of metal–ligand coordination bonds,BPbased nanocomposite hydrogels possess tunable mechanical properties,highly dynamic structures,and the capability to mediate controlled release of encapsulated therapeutic agents,thereby making them highly versatile for various biomedical applications.This review presents the comprehensive overview of recent developments in BP-based nanocomposite hydrogels with an emphasis on the properties of embedded nanoparticles(NPs)and interactions between hydrogel network and NPs.Furthermore,various challenges in the biomedical applications of these hydrogels are discussed to provide an outlook of potential clinical translation. | Weihao Yuan Zhuo Li Xian Xie Zhi-Yong Zhang Liming Bian | 2020 | Bioactive Materials2020，5，4： | 7 |
| 3 | 中国成人糖尿病、血糖与结直肠癌发病率:针对50万人的前瞻性研究显示文摘背景糖尿病可致结直肠癌(CRC)的发病风险升高。糖尿病病程和非糖尿病患者的血糖与CRC发病风险之间的相关性仍不清楚。方法2004至2008年前瞻性中国Kadoofe Biobank研究从10个不同地区纳入了512 713名受试者。在10年随访期间,在基线无癌症史的510 136名受试者中共记录有3 024例新发CRC病例(1 745例结肠癌,1 716例直肠癌)。应用Cox回归分析对糖尿病(入组前诊断或筛查发现的)或无糖尿病病史者随机血糖(RPG)水平与CRC发病相关性的校正风险比(HR)进行估计。结果基线时,共有5.8%的受试者患有糖尿病。糖尿病患者发生CRC的校正HR为1.18(95%可信区间1.04~1.33),且发生结肠癌与直肠癌的风险相当[1.19(1.01~1.39)比1.14(0.96~1135)]。这些患者发生CRC的HR随糖尿病病程的延长而下降(趋势P值为0.03)。在入组前无糖尿病的受试者中,其RPG水平与CRC发病呈正相关,基线RPG每升高1 mmol/L其发生CRC的校正HR为1.04(1.02~1.05),且发生结肠癌与直肠癌的风险亦相当[1.03(1.01~1.05)比1.04(1.02~1.06)]。在男性中,糖尿病和RPG与CRC发病风险的相关性高于女性,但其差异无统计学意义(异质性检验的P值分别为0.3和0.2)。讨论在中国成年人中,未诊断糖尿病者其糖尿病和升高的血糖水平与CRC发病风险升高相关。 | Yuanjie Pang Christiana Kartsonak yu Guo Yiping Chen Ling Yang Zheng Bian Fiona Bragg Iona Y Millwood Leijia Shen Songgen Zhou Jiben Liu Junshi Chen Liming Li Michael V Holmes Zhengming Ghen 霍永丰(译) | 2019 | 英国医学杂志中文版2019，22，1： | 6 |
| 4 | Inheritance of growth and survival in two 9-year-old, open-pollinated progenies of an advanced breeding population of Chinese firs in southeastern China显示文摘Tree growth traits(tree height,DBH and stem volume) and survival from two 9-year-old,open-pollinated progeny tests of Chinese fir were investigated for heritability,genotype 9 environment interaction,age-age genetic correlation and selection efficiency.The 97 and 79 families planted at two sites were collected from the thirdcycle seed orchard.Individual heritability was estimated between 0.05 and 0.21 for tree height,DBH,and volume and between 0.45 and 1.0 for survival.Family heritability was between 0.20 and 1.14.Significant genotype 9 environment interaction was observed for the three growth traits.Type B genetic correlation was between 0.41 and 0.67 with an increasing trend as tree grows.High age-age genetic correlation was observed with correlation reaching 0.9 after age 4 for height,DBH,and volume.The genetic gains were estimated at 3.26,3.39 and 5.98 % for tree height,DBH,and volume with 10 % selection intensity.The implication for advanced tree breeding in Chinese fir is discussed. | Renhua Zheng Zhou Hong Shunde Su Liming Bian Hui Xiao Jisen Shi Harry X.

| 5 | Building Osteogenic Microenvironments with a Double-Network Composite Hydrogel for Bone Repair显示文摘The critical factor determining the in vivo effect of bone repair materials is the microenvironment,which greatly depends on their abilities to promote vascularization and bone formation.However,implant materials are far from ideal candidates for guiding bone regeneration due to their deficient angiogenic and osteogenic microenvironments.Herein,a double-network composite hydrogel combining vascular endothelial growth factor(VEGF)-mimetic peptide with hydroxyapatite(HA)precursor was developed to build an osteogenic microenvironment for bone repair.The hydrogel was prepared by mixing acrylatedβ-cyclodextrins and octacalcium phosphate(OCP),an HA precursor,with gelatin solution,followed by ultraviolet photo-crosslinking.To improve the angiogenic potential of the hydrogel,QK,a VEGF-mimicking peptide,was loaded in acrylatedβ-cyclodextrins.The QK-loaded hydrogel promoted tube formation of human umbilical vein endothelial cells and upregulated the expression of angiogenesis-related genes,such as Flt1,Kdr,and VEGF,in bone marrow mesenchymal stem cells.Moreover,QK could recruit bone marrow mesenchymal stem cells.Furthermore,OCP in the composite hydrogel could be transformed into HA and release calcium ions facilitating bone regeneration.The double-network composite hydrogel integrated QK and OCP showed obvious osteoinductive activity.The results of animal experiments showed that the composite hydrogel enhanced bone regeneration in skull defects of rats,due to perfect synergistic effects of QK and OCP on vascularized bone regeneration.In summary,improving the angiogenic and osteogenic microenvironments by our double-network composite hydrogel shows promising prospects for bone repair. | Jiaying Li Jinjin Ma Qian Feng En Xie Qingchen Meng Wenmiao Shu Junxi Wu Liming Bian Fengxuan Han Bin Li | 2023 | Research2023，，3： | 3 |
| 6 | Spatial analysis increases efficiency of progeny testing of Chinese fir显示文摘We used spatial, global trend and post-blocking analysis to examine the effectiveness of a progeny trial in a tree breeding program for Chinese fir(Cunninghamia lanceolata(Lamb.) Hook) on a hilly site with an environmental gradient from hill top to bottom. Diameter at breast height(DBH) and tree height data had significant spatial auto-correlations among rows and columns. Adding a firstorder separable autoregressive term more effectively modelled the spatial variation than did the incomplete block(IB)model used for the experimental design. The spatial model also accounted for effects of experimental design factors and greatly reduced residual variances. The spatial analysis relative to the IB analysis improved estimation of genetic parameters with the residual variance reduced 13 and 19%for DBH and tree height, respectively; heritability increased35 and 51% for DBH and tree height, respectively; and genetic gain improved 3–5%. Fitting global trend and postblocking did not improve the analyses under IB model. The use of a spatial model or combined with a design model is recommended for forest genetic trials, particularly with global trend and local spatial variation of hilly sites. | Liming Bian Renhua Zheng Shunde Su Huazhong Lin Hui Xiao Harry Xiaming Wu Jisen Shi | 2017 | Journal of Forestry Research2017，28，3： | 3 |

| 8 | Auxin signaling module OsSK41-OsIAA10-OsARF regulates grain yield traits in rice显示文摘Auxin is an important phytohormone in plants, and auxin signaling pathways in rice play key roles in regulating its growth, development, and productivity. To investigate how rice grain yield traits are regulated by auxin signaling pathways and to facilitate their application in rice improvement, we validated the functional relationships among regulatory genes such as OsIAA10, OsSK41, and OsARF21 that are involved in one of the auxin(OsIAA10) signaling pathways. We assessed the phenotypic effects of these genes on several grain yield traits across two environments using knockout and/or overexpression transgenic lines.Based on the results, we constructed a model that showed how grain yield traits were regulated by OsIAA10 and OsTIR1, OsAFB2, and OsSK41 and OsmiR393 in the OsSK41-OsIAA10-OsARF module and by OsARF21 in the transcriptional regulation of downstream auxin response genes in the OsSK41-OsIAA10-OsARF module. The population genomic analyses revealed rich genetic diversity and the presence of major functional alleles at most of these loci in rice populations. The strong differentiation of many major alleles between Xian/indica and Geng/japonica subspecies and/or among modern varieties and landraces suggested that they contributed to improved productivity during evolution and breeding. We identified several important aspects associated with the genetic and molecular bases of rice grain and yield traits that were regulated by auxin signaling pathways.We also suggested rice auxin response factor(OsARF) activators as candidate target genes for improving specific target traits by overexpression and/or editing subspecies-specific alleles and by searching and pyramiding the ‘best' gene allelic combinations at multiple regulatory genes in auxin signaling pathways in rice breeding programs. | Fuying Ma Fan Zhang Yu Zhu Dengyong Lan Peiwen Yan Ying Wang Zejun Hu Xinwei Zhang Jian Hu Fuan Niu Mingyu Liu Shicong He Jinhao Cui Xinyu Yuan Ying Yan Shujun Wu Liming Cao Hongwu Bian Jinshui Yang Zhikang Li Xiaojin Luo | 2023 | Journal of Integrative Plant Biology2023，65，7： | 1 |

| 10 | Surface decoration of development-inspired synthetic N-cadherin motif via Ac-BP promotes osseointegration of metal implants显示文摘Research works on the synergistic effect of surface modified bioactive molecules and bone metal implants have been highlighted.N-cadherin is regarded as a key factor in directing cell-cell interactions during the mesenchymal condensation preceding the osteogenesis in the musculoskeletal system.In this study,the N-cadherin mimetic peptide(Cad)was biofunctionalized on the titanium metal surface via the acryloyl bisphosphonate(Ac-BP).To learn the synergistic effect of N-cadherin mimetic peptide,when tethered with titanium substrates,on promoting osteogenic differentiation of the seeded human mesenchymal stem cells(hMSCs)and the osseointegration at the bone-implant interfaces.Results show that the conjugation of N-cadherin mimetic peptide with Ac-BP promoted the osteogenic gene markers expression in the hMSCs.The biofunctionalized biomaterial surfaces promote the expression of the Wnt/β-catenin downstream axis in the attached hMSCs,and then enhance the in-situ bone formation and osseointegration at the bone-implant interfaces.We conclude that this N-cadherin mimetic peptide tethered on Ti surface promote osteogenic differentiation of hMSCs and osseointegration of biomaterial implants in vitro and in vivo.These findings demonstrate the importance of the development-inspired surface bioactivation of metal implants and shed light on the possible cellular mechanisms of the enhanced osseointegration. | Meiling Zhu Kunyu Zhang Lu Feng Sien Lin Qi Pan Liming Bian Gang Li | 2021 | Bioactive Materials2021，6，5： | 1 |

| 13 | Enhancing cartilage repair with optimized supramolecular hydrogel-based scaffold and pulsed electromagnetic field显示文摘Functional tissue engineering strategies provide innovative approach for the repair and regeneration of damaged cartilage.Hydrogel is widely used because it could provide rapid defect filling and proper structure support,and is biocompatible for cell aggregation and matrix deposition.Efforts have been made to seek suitable scaffolds for cartilage tissue engineering.Here Alg-DA/Ac-β-CD/gelatin hydrogel was designed with the features of physical and chemical multiple crosslinking and self-healing properties.Gelation time,swelling ratio,biodegradability and biocompatibility of the hydrogels were systematically characterized,and the injectable self-healing adhesive hydrogel were demonstrated to exhibit ideal properties for cartilage repair.Furthermore,the new hydrogel design introduces a pre-gel state before photo-crosslinking,where increased viscosity and decreased fluidity allow the gel to remain in a semi-solid condition.This granted multiple administration routes to the hydrogels,which brings hydrogels the ability to adapt to complex clinical situations.Pulsed electromagnetic fields(PEMF)have been recognized as a promising solution to various health problems owing to their noninvasive properties and therapeutic potentials.PEMF treatment offers a better clinical outcome with fewer,if any,side effects,and wildly used in musculoskeletal tissue repair.Thereby we propose PEMF as an effective biophysical stimulation to be 4th key element in cartilage tissue engineering.In this study,the as-prepared Alg-DA/Ac-β-CD/gelatin hydrogels were utilized in the rat osteochondral defect model,and the potential application of PEMF in cartilage tissue engineering were investigated.PEMF treatment were proven to enhance the quality of engineered chondrogenic constructs in vitro,and facilitate chondrogenesis and cartilage repair in vivo.All of the results suggested that with the injectable self-healing adhesive hydrogel and PEMF treatment,this newly proposed tissue engineering strategy revealed superior clinical potential for cartilage defect treatment. | Yucong Li Linlong Li Ye Li Lu Feng Bin Wang Ming Wang Haixing Wang Meiling Zhu Yongkang Yang Erik IWaldorff Nianli Zhang Ingmar Viohl Sien Lin Liming Bian Wayne Yuk-Wai Lee Gang Li | 2023 | Bioactive Materials2023，，4： | 1 |

| 17 | Conformationally Dynamic Supramolecular Single Chain Nanogels for Mutilscale Biomechanical Regulation of Stem Cells显示文摘Objective The binding of cell adhesive peptides(such as RGD)to integrins initiates the recruitment of cytoplasmic adaptor proteins(e.g.,vinculin)and the formation of focal adhesion(FA)complexes required for cell adhesion.The ability to manipulate this ligand-mediated cell adhesion process is crucial for regulating cell migration,cell differentiation,injury healing,and immune response.Some recent studies reported the importance of the tether length/mobility of the cell adhesive ligands in regulating the traction force development of cells.In the native cellular microenvironment,such a dynamic change in the nanoscale tether length of bioactive ligands is often mediated by conformational changes of the structural proteins due to protein folding or degradation.However,no prior studies have demonstrated the modulation of the ligand tether mobility by controlling the intramolecular folding of polymeric linkers.Unfoldable synthetic macromolecules with easy synthetic routes and controllable structures,such as supramolecular host-guest single chain nanogels(SCNGs),are ideal candidates for mimicking the changes in the tether mobility of bioactive ligands via biorthogonal triggers.Methods S,S’-bis(a’a’-dimethyl-a’’-propargyl acetate)trithiocarbonate was first used to mediate the RAFT polymerization of N,N-dimethyl acrylamide,vinyl-adamantane and vinyl-β-cyclodextrin to yield the ADA@CD-SCNGs.The preparation of the unfoldable host-guest SCNGs was evidenced by the by gel permeation chromatography,proton nuclear magnetic resonance spectroscopy,atomic force microscopy and dynamic light scattering.Then the RGD peptide was conjugated to the alkynyl group on one end of the SCNGs before immobilizing the material on the substrate,which was confirmed by scanning electron microscopy(SEM).The regulation of cell behaviours by unfolding of the SCNG-RGD was confirmed by immunofluorescence staining of vinculin and Yes-associated protein(YAP).Results The preparation of ADA@CD-SCNGs was confirmed by GPC which showed a unimodal molecular weight distribution.DLS and AFM data also proved that the SCNGs had an average diameter of 12±3nm.SEM images showed that SCNGs were conjugated as a linker of RGD peptide to thiolated glass substrate at an average density of 162±11 particles/μm2.These particles disappeared after adding free competitive ADA guest molecules,indicating the triggered unfolding of the tether SCNGs.In addition,the unfolding of supramolecular ADA@CD-SCNGs was also evidenced by a decrease in the GPC elution time and a slight increase in the apparent molecular weight.These results show that the immobilized ADA@CD-SCNGs can be unfolded to tune the tether length and mobility of the conjugated RGD ligands.Then we investigated the regulation of the cell behaviors on the substrate by triggering the unfolding of SCNG linkers.A critical level of traction force is required to effectively initiate and maintain integrin-mediated formation of FA complexes and subsequent mechano-transduction signaling.An increased tether length in cell-adhesive ligands can lead to a diminished cell traction force as if cells are adhering to soft substrates.Here,the unfolding of the ADA@CD-SCNG-RGD triggered by the addition of free ADA led to disassembly of the mature focal adhesions in the cells as evidenced by the reduced vinculin and F-actin in staining.Subsequently,nuclear YAP also decreased significantly because of the impaired mechano-sensing and diminished cell cytoskeleton tension.In addition,the extensively spread cells gradually became round after the medium was supplemented with free competitive ADA to unfold the SCNG linker.These finding demonstrates that the substrates with the unfolded ADA@CD-SCNG-RGD only supported weak cell adhesions.In contrast,on the substrate conjugated with the nonunfoldable MBA-SCNG-RGD linker,the addition of free ADA resulted in no change in the spread cell morphology and protein expressions.These results indicate that the unfoldable host-guest ADA@CD-SCNG can be used to manipulate the nanoscale presentation of ligands to regulate cell behaviors.Conclusions We demonstrate the application of SCNGs as the supramolecular linker to tune the nanoscale ligand tether length.These findings demonstrate that the strategy of manipulating the tether mobility of bioactive ligands by using supramolecular SCNGs as linkers provides a highly tunable,biomimetic,and bio-orthogonal approach to study the dynamic events of cell adhesion. | Liming Bian | 2019 | 医用生物力学2019，34，A01： | 0 |
| 18 | Complex coacervate-derived hydrogel with asymmetric and reversible wet bioadhesion for preventing UV light-induced morbidities显示文摘Protecting the skin from UV light irradiation in wet and underwater environments is challenging due to the weak adhesion of existing sunscreen materials but highly desired.Herein we report a polyethyleneimine/thioctic acid/titanium dioxide(PEI/TA/TiO_(2))coacervate-derived hydrogel with robust,asymmetric,and reversible wet bioadhesion and effective UV-light-shielding ability.The PEI/TA/TiO_(2)complex coacervate can be easily obtained by mixing a PEI solution and TA/TiO_(2)powder.The fluid PEI/TA/TiO_(2)coacervate deposited on wet skin can spread into surface irregularities and subsequently transform into a hydrogel with increased cohesion,thereby establishing interdigitated contact and adhesion between the bottom surface and skin.Meanwhile,the functional groups between the skin and hydrogel can form physical interactions to further enhance bioadhesion,whereas the limited movement of amine and carboxyl groups on the top hydrogel surface leads to low adhesion.Therefore,the coacervate-derived hydrogel exhibits asymmetric adhesiveness on the bottom and top surfaces.Moreover,the PEI/TA/TiO_(2)hydrogel formed on the skin could be easily removed using a NaHCO3 aqueous solution without inflicting damage.More importantly,the PEI/TA/TiO_(2)hydrogel can function as an effective sunscreen to block UV light and prevent UV-induced MMP-9 overexpression,inflammation,and DNA damage in animal skin.The advantages of PEI/TA/TiO_(2)coacervate-derived hydrogels include robust,asymmetric,and reversible wet bioadhesion,effective UV light-shielding ability,excellent biocompatibility,and easy preparation and usage,making them a promising bioadhesive to protect the skin from UV light-associated damage in wet and underwater environments. | Xin Peng Yuan Li Menghui Liu Zhuo Li Xuemei Wang Kunyu Zhang Xin Zhao Gang Li Liming Bian | 2023 | Bioactive Materials2023，，12： | 0 |
| 19 | Lung cancer risk score for ever and never smokers in China显示文摘Background:Most lung cancer risk prediction models were developed in European and North-American cohorts of smokers aged≥55 years,while less is known about risk profiles in Asia,especially for never smokers or individuals aged<50 years.Hence,we aimed to develop and validate a lung cancer risk estimate tool for ever and never smokers across a wide age range.Methods:Based on the China Kadoorie Biobank cohort,we first systematically selected the predictors and explored the nonlinear association of predictors with lung cancer risk using restricted cubic splines.Then,we separately developed risk prediction models to construct a lung cancer risk score(LCRS)in 159,715 ever smokers and 336,526 never smokers.The LCRS was further validated in an independent cohort over a median follow-up of 13.6 years,consisting of 14,153 never smokers and 5,890 ever smokers.Results:A total of 13 and 9 routinely available predictors were identified for ever and never smokers,respectively.Of these predictors,cigarettes per day and quit years showed nonlinear associations with lung cancer risk(Pnon-linear<0.001).The curve of lung cancer incidence increased rapidly above 20 cigarettes per day and then was relatively flat until approximately 30 cigarettes per day.We also observed that lung cancer risk declined sharplywithin the first 5 years of quitting,and then continued to decrease but at a slower rate in the subsequent years.The 6-year area under the receiver operating curve for the ever and never smokers’models were respectively 0.778 and 0.733 in the derivation cohort,and 0.774 and 0.759 in the validation cohort.In the validation cohort,the 10-year cumulative incidence of lung cancerwas 0.39%and 2.57%for ever smokers with low(<166.2)and intermediate-high LCRS(≥166.2),respectively.Never smokers with a high LCRS(≥21.2)had a higher 10-year cumulative incidence rate than those with a low LCRS(<21.2;1.05%vs.0.22%).An online risk evaluation tool(LCKEY;http://gffzz0332d520339f4200h5fw0qqkv9pb56u9f.ffgz.tsg.suse.edu.cn/lckey/web)was developed to facilitate the use of LCRS.Conclusions:The LCRS can be an effective risk assessment tool designed for ever and never smokers aged 30 to 80 years. | Zhimin Ma Jun Lv Meng Zhu Canqing Yu Hongxia Ma Guangfu Jin Yu Guo Zheng Bian Ling Yang Yiping Chen Zhengming Chen Zhibin Hu Liming Li Hongbing Shen | 2023 | Cancer Communications2023，43，8： | 0 |
| 20 | Ligand Engineering in Tin-Based Perovskite Solar Cells显示文摘Perovskite solar cells(PSCs)have attracted aggressive attention in the photovoltaic field in light of the rapid increasing power conversion efficiency.However,their large-scale application and commercialization are limited by the toxicity issue of lead(Pb).Among all the lead-free perovskites,tin(Sn)-based perovskites have shown potential due to their low toxicity,ideal bandgap structure,high carrier mobility,and long hot carrier lifetime.Great progress of Sn-based PSCs has been realized in recent years,and the certified efficiency has now reached over 14%.Nevertheless,this record still falls far behind the theoretical calculations.This is likely due to the uncontrolled nucleation states and pronounced Sn(Ⅳ)vacancies.With insights into the methodologies resolving both issues,ligand engineering-assisted perovskite film fabrication dictates the state-of-the-art Sn-based PSCs.Herein,we summarize the role of ligand engineering during each state of film fabrication,ranging from the starting precursors to the ending fabricated bulks.The incorporation of ligands to suppress Sn~(2+)oxidation,passivate bulk defects,optimize crystal orientation,and improve stability is discussed,respectively.Finally,the remained challenges and perspectives toward advancing the performance of Sn-based PSCs are presented.We expect this review can draw a clear roadmap to facilitate Sn-based PSCs via ligand engineering. | Peizhou Li Xiangrong Cao Jingrui Li Bo Jiao Xun Hou Feng Hao Zhijun Ning Zuqiang Bian Jun Xi Liming Ding Zhaoxin Wu Hua Dong | 2023 | Nano-Micro Letters2023，15，10： | 0 |
