| 1 | Generalized non-linear strength theory and transformed stress space显示文摘Based on the test data of frictional materials and previous research achievements in this field, a generalized non-linear strength theory (GNST) is proposed. It describes non-linear strength properties on the π-plane and the meridian plane using a unified formula, and it includes almost all the present non-linear strength theories, which can be used in just one material. The shape of failure function of the GNST is a smooth curve between the SMP criterion and the Mises criterion on the π-plane, and an exponential curve on the meridian plane. Through the transformed stress space based on the GNST, the combination of the GNST and various constitutive models using p and q as stress parameters can be realized simply and rationally in three-dimensional stress state. | YAO Yangping LU Dechun ZHOU Annan ZOU Bo | 2004 | Science China(Technological Sciences)2004，47，6： | 57 |

| 3 | Profile Characteristics and Potential EnvironmentalEffect of Accumulated Phosphorus in Soils of Vegetable Fields in Beijing显示文摘Profile characteristics of accumulated P in 10 representative soils of vegetable fields in suburban districtsof Beijing were investigated. Bioavailability of the accumuIated P and its potential effect on the environmentwere studied in a greenhouse pot experiment and a soil column experiment. The results showed that theconcentration of Olsen-P in the 0-20 cm soil samples of the vegetable fields ranged from 22.1 to 358.0 mgkg-1, which was 2 to 10 times higher than that of the crop fields in the suburbs of Beijing. Most of theexcessive phosphorus was accumulated in the topsoils. The longer the soils cultivated with vegetables, thehigher the soil total P, Olsen-P and organic matter concentration. Accumulated P in the soils from vegetablefields had higher bioavailability. Application of phosphorus fertilizer could not increase the dry weights ofcucumbers, Chinese cabbage, and rape seedlings continuously planted.

| 5 | Fatigue behavior of Ti-6Al-4V cellular structures fabricated by additive manufacturing technique显示文摘Porous titanium and its alloys have been considered as promising replacement for dense implants, as they possess low elastic modulus comparable to that of compact human bones and are capable of providing space for in-growth of bony tissues to achieve a better fixation. Recently, the additive manufacturing(AM) method has been successfully applied to the fabrication of Ti-6 Al-4 V cellular meshes and foams.Comparing to traditional fabrication methods, the AM method offers advantages of accurate control of complex cell shapes and internal pore architectures, thus attracting extensive attention. Considering the long-term safety in the human body, the metallic cellular structures should possess high fatigue strength.In this paper, the recent progress on the fatigue properties of Ti-6 Al-4 V cellular structures fabricated by the AM technique is reviewed. The various design factors including cell shapes, surface properties, post treatments and graded porosity distribution affecting the fatigue properties of additive manufactured Ti-6 Al-4 V cellular structures were introduced and future development trends were also discussed. | Dechun Ren Shujun Li Hao Wang Wentao Hou Yulin Hao Wei Jin Rui Yang R.Devesh K.Misra Lawrence E.Murr | 2019 | Journal of Materials Science & Technology2019，35，2： | 15 |

| 7 | Immunopathobiology and therapeutic targets related to cytokines in liver diseases显示文摘Chronic liver injury with any etiology can progress to fibrosis and the end-stage diseases cirrhosis and hepatocellular carcinoma.The progression of liver disease is controlled by a variety of factors,including liver injury,inflammatory cells,inflammatory mediators,cytokines,and the gut microbiome.In the current review,we discuss recent data on a large number of cytokines that play important roles in regulating liver injury,inflammation,fibrosis,and regeneration,with a focus on interferons and T helper(Th)1,Th2,Th9,Th17,interleukin(IL)-1 family,IL-6 family,and IL-20 family cytokines.Hepatocytes can also produce certain cytokines(such as IL-7,IL-11;and IL-33),and the functions of these cytokines in the liver are briefly summarized.Several cytokines have great therapeutic potential,and some are currently being tested as therapeutic targets in clinical trials for the treatment of liver diseases,which are also described. | Yong He Seonghwan Hwang Yeni Ait Ahmed Dechun Feng Na Li Marcelle Ribeiro Fouad Lafdil Tatiana Kisseleva Gyongyi Szabo Bin Gao | 2021 | Cellular & Molecular Immunology2021，18，1： | 14 |
| 8 | Punicalagin ameliorates collagen-induced arthritis by downregulating M1 macrophage and pyroptosis via NF-κB signaling pathway显示文摘Rheumatoid arthritis(RA)is a chronic inflammatory disease that eventually leads to disability.Inflammatory cell infiltration,severe joint breaking and systemic bone loss are the main clinical symptoms.In this study,we established a collagen-induced arthritis(CIA)model and found a large number of M1 macrophages and pyroptosis,which are important sources of proinflammatory cytokines.Punicalagin(PUN)is an active substance extracted from pomegranate peel.We found that it inhibited joint inflammation,cartilage damage and systemic bone destruction in CIA mice.PUN effectively alleviated the high expression of inflammatory cytokines in synovial tissue in vivo.PUN treatment shifted macrophages from the M1 phenotype to the M2 phenotype after stimulation with lipopolysaccharide(LPS)and interferon(IFN)-γ.The expression of inducible nitric oxide synthase(i NOS)and other proinflammatory cytokines released by M1 macrophages was decreased in the PUN treatment group.However,simultaneously,the expression of markers of anti-inflammatory M2 macrophages,such as arginase(Arg)-1 and interleukin(IL)-10,was increased.In addition,PUN treatment attenuated pyroptosis by downregulating the expression of NLRP3 and caspase-1,thereby preventing inflammatory cell death resulting from the release of IL-1βand IL-18.Mechanistically,PUN inhibited the activation of receptor activators of the nuclear factor-κB(NF-κB)signaling pathway,which contributes to M1 polarization and pyroptosis of macrophages.We concluded that PUN ameliorated pathological inflammation by inhibiting M1 phenotype polarization and pyroptosis and has great potential as a therapeutic treatment for human RA. | Gaoran Ge Jiaxiang Bai Qing Wang Xiaolong Liang Huaqiang Tao Hao Chen Minggang Wei Junjie Niu Huilin Yang Yaozeng Xu Yuefeng Hao Yi Xue Dechun Geng | 2022 | Science China(Life Sciences)2022，65，3： | 14 |

| 10 | Stress Corrosion Cracking of X80 Steel in the Presence of Sulfate-reducing Bacteria显示文摘The systematic laboratory studies on the roles of sulfate-reducing bacteria(SRB) in the stress corrosion cracking(SCC) susceptibility of X80 steel subjected to cathodic potential have been conducted in a nearneutral pH soil solution by slow strain rate tests.The cathodic potential and SRB increase individually the SCC susceptibility of the steel in the soil solution.The positive role of the SRB activities in SCC susceptibility depends on the prolongation of pre-incubation time,and the SCC susceptibility of the steel increases under more negative potentials.What's more,the applied potentials and the presence of SRB work together in promoting the SCC susceptibility of the steel.But,the combined action becomes limited with decreasing cathodic potentials.The relationships between the plasticity loss and the permeable hydrogen concentration were established for the steel in the soil solution,regardless of under open circuit potential or cathodic potentials,in both the sterile and SRB inoculated conditions.The relationships are practically significant for the selection of safe cathodic protection(CP) potentials in the presence of SRB in soil environment. | Tangqing Wu Maocheng Yan Dechun Zeng Jin Xu Cheng Sun Changkun Yu Wei Ke | 2015 | Journal of Materials Science & Technology2015，31，4： | 11 |
| 11 | Assessing the numbers of SNPs needed to establish molecular IDs and characterize the genetic diversityof soybean cultivars derived from Tokachi nagaha显示文摘The development of a core set of SNP molecular markers that could be widely used in soybean genetic research would greatly facilitate research into the genetic diversity of soybean.We conducted an analysis of Tokachi nagaha and 137 of its descendant soybean cultivars using 4044 SNP markers with the goal of determining the appropriate number of single-nucleotide polymorphisms(SNPs)needed to construct unambiguous molecular IDs and characterize genetic diversity based on a genetic distance matrix correlation method.When the number of SNPs was held constant,the number of accession pairs that could be distinguished increased as the polymorphism informative content(PIC)value of the SNPs increased.A core panel of 20 selected SNPs from 11 linkage groups with a mean PIC value of 0.3703 and a range of 0.3640–0.3749 was able to identify almost all of the accession pairs in our study[9445 pairs(99.92%)].The eight accession pairs that could not be identified with this core SNP set all originated from the same province and some of them had the same parental cultivars.The molecular IDs of the 138 accessions were constructed using the core 20 SNPs.It is known that both the number of SNPs and PIC values should be considered when SNPs are selected for use in the analysis of genetic diversity.In this study,when the PIC value was 0.3460,the correlation coefficient between the genetic distance matrices associated with a panel of 200 SNPs and the total population was>0.800,indicating satisfactory correlation.Our high-accuracy,high-resolution core SNP panel for germplasm fingerprinting and our findings about assessing genetic diversity will likely markedly improve the management and utilization efficiency of soybean germplasm resources. | Zhangxiong Liu Jun Li Xuhong Fan Nang Myint Phyu Sin Htwe Shuming Wang Wen Huang Jiyu Yang Lili Xing Lijun Chen Yinghui Li Rongxia Guan Ruzhen Chang Dechun Wang Lijuan Qiu | 2017 | The Crop Journal2017，5，4： | 10 |
| 12 | Design optimization of a C-band traveling-wave accelerating structure for a compact X-ray Free Electron Laser facility显示文摘The research and development of a C-band (5712 MHz) high gradient traveling-wave accelerating structure has been in progress for some years at the Shanghai Institute of Applied Physics, Chinese Academy of Sciences. Conceptual design of the accelerating structure has been accomplished, and verified by cold testing an experimental model. The first prototype structure is now ready for high RF power tests. To develop a robust high gradient C-band accelerating structure, an optimized constant gradient structure with a 4 /5 operating mode for future X-ray Free Electron Laser facilities is proposed in this paper. This scheme can improve the breakdown stability and beam quality. The high power RF system, four operating modes and disk iris shape are analyzed and optimized. | FANG WenCheng GU Qiang TONG DeChun ZHAO ZhenTang | 2011 | Chinese Science Bulletin2011，56，32： | 9 |
| 13 | Real-time rapid prediction of variations of Earth's rotational rate显示文摘Real-time rapid prediction of variations of the Earth's rotational rate is of great scientific and practical importance. However, due to the complicated time-variable characteristics of variations of the Earth's rotational rate (i.e., length of day, LOD), it is usually difficult to obtain satisfactory predictions by con-ventional linear time series analysis methods. This study employs the nonlinear artificial neural net-works (ANN) to predict the LOD variations. The topology of the ANN model is determined by minimizing the root mean square errors (RMSE) of the predictions. Considering the close relationships between the LOD variations and the atmospheric circulation movement, the operational prediction series of axial atmospheric angular momentum (AAM) is incorporated into the ANN model as an additional input in the real-time rapid prediction of LOD variations with 1-5 days ahead. The results show that the LOD pre-diction is significantly improved after introducing the operational prediction series of AAM into the ANN model. | WANG QiJie LIAO DeChun ZHOU YongHong | 2008 | Chinese Science Bulletin2008，53，7： | 8 |
| 14 | ROS signaling cascades:dual regulations for osteoclast and osteoblast显示文摘Accumulating evidence indicates that intracellular reactive oxygen species(ROS)production is highly involved in bone homeostasis by intervening osteoclast or osteoblast differentiation.Interestingly,ROS that are known as oxidizing agents exert dose-dependent biphasic properties in bone remodeling,including preventing osteoblast activity but accelerating osteoclast resorption.ROS mainly composed of superoxide anion radical,hydroxyl radical,nitric oxide,and two-electron reduction product hydrogen peroxide,which are important components to regulate bone cell metabolism and function in mammal skeleton.These free radicals can be partly produced in bone and boosted in an inflammation state.Although numerous researches have emphasized the impacts of ROS on bone cell biology and verified the mechanism of ROS signaling cascades,the recapitulatory commentary is necessary.In this review article,we particularly focus on the regulation of the intracellular ROS and its potential mechanism impacting on cell-signaling transduction in osteoclast and osteoblast differentiation for preferable understanding the pathogenesis and searching for novel therapeutic protocols for human bone diseases. | Huaqiang Tao Gaoran Ge Xiaolong Liang Weicheng Zhang Houyi Sun Meng Li Dechun Geng | 2020 | Acta Biochimica et Biophysica Sinica2020，52，10： | 8 |
| 15 | Resurrection of the Genus Leptomantis, with Description of a New Genus to the Family Rhacophoridae(Amphibia:Anura)显示文摘Genus Rhacophorus Kuhl and Van Hasselt, 1 822 is one of the most diverse genera of the family Rhacophoridae, and its taxonomy of genus Rhacophorus faces major challenges because of rapidly described new species and complex interspecies relations. In this study, we investigate the generic taxonomy within the genus Rhacophorus based on 1 972 bp of mitochondrial genes(12S rRNA, tRNA-val and 16S rRNA), containing 102 sequences from 58 species. The results reveal three well-supported and highly diverged matrilines that correspond with morphological characteristics and geographic distribution. Accordingly, we consider these three lineages as distinct genera: Rhacophorus sensu stricto, resurrected genus Leptomantis Peters, 1867, and the genus Zhangixalus gen. nov. | Dechun JIANG Ke JIANG Jinlong REN Jun WU Jiatang LI | 2019 | Asian Herpetological Research2019，10，1： | 8 |
| 16 | Protective effects of human umbilical cord mesenchymal stem cell vein transplantation against spinal cord ischemia/reperfusion injury in rats显示文摘BACKGROUND: The majority of studies addressing spinal cord ischemia/reperfusion injury (SCIRI) have focused on drugs, proteins, cytokines, and various surgical techniques. A recent study reports that human umbilical cord mesenchymal stem cell (hUCMSC) transplantation achieves good therapeutic effects, but the mechanisms underlying nerve protection remain poorly understood. OBJECTIVE: To observe survival of transplanted hUCMSCs in SCIRI rat models and the influence on motor function in the hind limbs, to determine interleukin-8 expression and cellular apoptosis in spinal cord tissues, and to verify the hypothesis that hUCMSC transplantation exhibits protective effects on SCIRI. DESIGN, TIME AND SETTING: A randomized, controlled, animal experiment was performed at the Laboratory of the Department of Orthopedics in the First Affiliated Hospital of Soochow University, China between January 2007 and December 2008. MATERIALS: hUCMSCs were harvested from umbilical cord blood of healthy pregnant women after parturition in the Obstetrical Department of the First Affiliated Hospital of Soochow University, China. Rabbit anti-human BrdU monoclonal antibody was provided by DAKO, USA. Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) Kit and enzyme-linked immunosorbent assay (ELISA) Kit were purchased by Wuhan Boster, China. METHODS: A total of 72 healthy, Wistar, adult rats were randomly assigned to three groups: sham-surgery, model, and transplantation, with 24 rats in each group. SCIRI was induced in the model and transplantation groups via the abdominal aorta block method. The infrarenal abdominal aorta was not blocked in the sham-surgery group. Prior to abdominal aorta occlusion, 0.2-0.3 mL bromodeoxyuridine (BrdU)-labeled hUCMSCs suspension (cell concentration 5 × 103/μL) was injected through the great saphenous vein of the hind limb, and an equal volume of physiological saline was administered to the model and sham-surgery groups. MAIN OUTCOME MEASURES: Pathological observation of rat spinal cord tissues was performed by hematoxylin-eosin staining at 6, 24, and 48 hours post-surgery. Immunohistochemistry was applied to determine hUCMSCs survival in the spinal cord. The amount of cellular apoptosis and interleukin-8 expression in spinal cord tissues was assayed utilizing the TUNEL and ELISA methods, respectively. Motor function in the hind limbs was evaluated according to Jacob's score. RESULTS: Numerous BrdU-positive cells were observed in spinal cord tissues from the transplantation group. The number of apoptotic cells and interleukin-8 levels significantly decreased in the transplantation group (P < 0.05), pathological injury was significantly ameliorated, and motor function scores significantly increased (P < 0.05) compared with the model group. CONCLUSION: Via vein transplantation, hUCMSCs were shown to reach and survive in the injury area. Results suggested that the transplanted hUCMSCs contributed to significantly improved pathological changes in the injured spinal cord, as well as motor function, following SCIRI. The protective mechanism correlated with inhibition of cellular apoptosis and reduced production of inflammatory mediators. | Jun Zou Minfeng Gan Xuesong Zhu Dechun Geng Huilin Yang | 2010 | Neural Regeneration Research2010，5，3： | 7 |
| 17 | Regulation of the inflammatory cycle by a controllable release hydrogel for eliminating postoperative inflammation after discectomy显示文摘Surgery is the final choice for most patients with intervertebral disc degeneration(IDD).Operation-caused trauma will cause inflammation in the intervertebral disc.Serious inflammation will cause tissue defects and induce tissue degeneration,IDD recurrence and the occurrence of other diseases.Therefore,we proposed a scheme to treat recurrence after discectomy by inhibiting inflammation with an aspirin(ASP)-loaded hydrogel to restore the mechanical stability of the spine and relieve local inflammation.ASP-liposomes(ASP-Lips)were incorporated into a photocrosslinkable gelatin-methacryloyl(GelMA)via mixing.This material can effectively alleviate inflammation by inhibiting the release of high mobility group box 1(HMGB1)from the nucleus to the cytoplasm.We further assessed the expression of inflammatory cytokines,such as interleukin 6(IL-6)and tumor necrosis factor-α(TNF-α),and degeneration-related factors,such as type II collagen(COL-2),Aggrecan,matrix metallopeptidases-3(MMP-3),MMP-13,a disintegrin and metalloproteinase with thrombospondin motifs-4(ADAMTS-4)and ADAMTS-5 in rat nucleus pulpous cells.The level of IDD was analyzed through H&E,safranin-O staining and immunohistochemistry in rabbit samples.In vitro,we found that ASP-Lip@GelMA treatment significantly decreased inflammatory cytokines,MMP-3 and-13,and ADAMTS-4 and-5 and up-regulated COL-2 and Aggrecan via the inhibited release of HMGB-1 from the nucleus.In vivo,ASP-Lip@GelMA can effectively inhibit inflammation of local tissue after disc surgery and fill local tissue defects.This composite hydrogel system is a promising way to treat the recurrence of IDD after surgery without persistent complications. | Yu Liu Jiacheng Du Peng Peng Ruoyu Cheng Jiayi Lin Congxin Xu Huilin Yang Wenguo Cui Haiqing Mao Yuling Li Dechun Geng | 2021 | Bioactive Materials2021，6，1： | 6 |

| 19 | Protective effects of sirtuin 3 on titanium particle-induced osteogenic inhibition by regulating the NLRP3 inflammasome via the GSK-3β/β-catenin signalling pathway显示文摘Periprosthetic osteolysis(PPO)remains the key factor in implant failure and subsequent revision surgery and is mainly triggered by wear particles.Previous studies have shown that inhibition of osteoblastic differentiation is the most widespread incident affecting the interface of trabecular and loosening prostheses.Additionally,the NLRP3 inflammasome is activated by prosthetic particles.Sirtuin3,an NAD+-dependent deacetylase of mitochondria,regulates the function of mitochondria in diverse activities.However,whether SIRT3 can mitigate wear debris-induced osteolysis by inhibiting the NLRP3 inflammasome and enhancing osteogenesis has not been previously reported.Therefore,we investigated the role of SIRT3 during the process of titanium(Ti)particle-induced osteolysis.We revealed that upregulated SIRT3 dramatically attenuated Ti particle-induced osteogenic inhibition through suppression of the NLRP3 inflammasome and improvement of osteogenesis in vivo and in vitro.Moreover,we found that SIRT3 interference in the process of Ti particle-induced osteolysis relied on the GSK-3β/β-catenin signalling pathway.Collectively,these findings indicated that SIRT3 may serve as a rational new treatment against debris-induced PPO by deacetylase-dependent inflammasome attenuation. | Kai Zheng Jiaxiang Bai Ning Li Meng Li Houyi Sun Weicheng Zhang Gaoran Ge Xiaolong Liang Huaqiang Tao Yi Xue Yuefeng Hao Chen Zhu Yaozeng Xu Dechun Geng | 2021 | Bioactive Materials2021，6，10： | 5 |
| 20 | Multilayer black phosphorus as saturable absorber for an Er:Lu_(2)O_(3) laser at~3 μm显示文摘Multilayer black phosphorus(BP) nanoplatelets of different thicknesses were prepared by the liquid phase exfoliation method and deposited onto yttrium aluminum garnet substrates to form saturable absorbers(SAs). These were characterized with respect to their thickness-dependent saturable absorption properties at 3 μm. The BP-SAs were employed in a passively Q-switched Er:Lu_2O_3 laser at 2.84 μm. By using BP exfoliated in different solvents,stable pulses as short as 359 ns were generated at an average output power of up to 755 m W. The repetition rate in the experiment was 107 k Hz, corresponding to a pulse energy of 7.1 μJ. These results prove that BP-SAs have a great potential for optical modulation in the mid-infrared range. | Mingqi Fan Tao Li Shengzhi Zhao Guiqiu Li Xiaochun Gao Kejian Yang Dechun Li Christian Krankel | 2016 | Photonics Research2016，4，5： | 5 |
