| 1 | A draft sequence of the rice (Oryza sativa ssp. indica) genome显示文摘The sequence of the rice genome holds fundamental information for its biology, including physiology, genetics, development, and evolution, as well as information on many beneficial phenotypes of economic significance. Using a 'whole genome shotgun' approach, we have pro-duced a draft rice genome sequence of Oryza sativa ssp. in-dica, the major crop rice subspecies in China and many other regions of Asia. The draft genome sequence is constructed from over 4.3 million successful sequencing traces with an accumulative total length of 2214.9 Mb. The initial assembly of the non-redundant sequences reached 409.76 Mb in length, based on 3.30 million successful sequencing traces with a total length of 1797.4 Mb from an indica variant cultivar 93-11, giving an estimated coverage of 95.29% of the rice genome with an average base accuracy of higher than 99%.

| 2 | High-conductivity free-standing Li_(6)PS_(5)Cl/poly(vinylidene difluoride)composite solid electrolyte membranes for lithium-ion batteries显示文摘Bulk-type all-solid-state batteries(ASSBs)using sulfide solid electrolyte are considered as a promising alternative to commercial lithium-ion batteries owing to their high energy density and safety.However,cell energy density is often comparatively low due to use of a thick solid electrolyte separator and a lithium alloy as anode.For achieving high-performance ASSBs,creating a thin free-standing electrolyte with high-conductivity and good cycling stability against lithium anode is essential.In this work,we present Li_(6)PS_(5)Cl/poly(vinylidene difluoride)(LPSCl/PVDF)composite electrolytes prepared by a slurry method.The influence of the PVDF content on the microstructure,morphology,ionic conductivity and activation energy of the LPSCl/PVDF electrolytes is systematically investigated.Free-standing LPSCl/PVDF membranes with a thickness of 100-120 mm and a high ionic conductivity of about 1·10^(-3) S cm^(-1) at 25℃ are obtained.After adding PVDF to the LPSCl electrolyte,the cycling stability of the LPSCl electrolyte against lithium metal improves significantly.Therefore,LPSCl/PVDF composite electrolytes are promising candidates to be used in ASSBs. | Shuo Wang Xue Zhang Sijie Liu Chengzhou Xin Chuanjiao Xue Felix Richter Liangliang Li Lizhen Fan Yuanhua Lin Yang Shen Jurgen Janek Ce-Wen Nan | 2020 | Journal of Materiomics2020，6，1： | 5 |
| 3 | Verification of Mutagen Function of Zeocin in Nannochloropsis oceanica Through Transcriptome Analysis显示文摘Zeocin can cause double strand breaks of DNA and thus is frequently used as a selective antibiotic of eukaryotic Sh ble transformants. In non-transformation system, Zeocin may function as a mutagen if not totally lethal. To verify such function of Zeocin, we mutated Nannochloropsis oceanica by increasing the concentration of Zeocin in medium gradually, and isolated a N. oceanica strain(single cell culture) which survived Zeocin up to 10.0μg mL^(-1). The Zeocin-tolerant strain entered the exponential growth phase later and grew slower than the wild strain. Transcriptome profiling showed that the Zeocin-tolerant N. oceanica strain survived Zeocin mainly by adapting(heritable), rather than acclimating(plastic) to Zeocin. Hence mutating N. oceanica with Zeocin was approved effective. Meanwhile, the physiological characteristics of this Zeocin-tolerant strain were demonstrated. As we proposed, N. oceanica tolerated Zeocin by strengthening its protein degradation and antioxidation. The genes controlling cell division and cellular response to stimuli may also have played important roles in the reduction of growth and the tolerance to Zeocin. Our findings evidenced that Zeocin can serve as an appropriate mutagen of microalgae. Creating variations through mutation with Zeocin may help to study the genetic basis of the traits of this monoploidy and asexual microalga, as well as improve its production. | LIN Genmei WANG Yamei GUO Li DING Haiyan HU Yongmei LIANG Sijie ZHANG Zhongyi YANG Guanpin | 2017 | Journal of Ocean University of China2017，16，3： | 5 |
| 4 | Uptake of graphene enhanced the photophosphorylation performed by chloroplasts in rice plants显示文摘New and enhanced functions were potentially imparted to the plant organelles after interaction with nanoparticles.In this study,we found that∼44%and∼29%of the accumulated graphene in the rice leaves passively transported to the chloroplasts and thylakoid,respectively,significantly enhanced the fluorescence intensity of chloroplasts,and promoted about 2.4 times higher adenosine triphosphate production than that of controls.The enhancement of graphene on the photophosphorylation was ascribed to two reasons:One is that graphene facilitates the electron transfer process of photosystem II in thylakoid,and the other is that graphene protects the photosystem II against photo-bleaching by acting as a scavenger of reactive oxygen species.Overall,our work here confirmed that graphene translocating in the thylakoid promoted the photosynthetic activity of chloroplast in vivo and in vitro,providing new opportunities for designing biomimetic materials to enhance the solar energy conversion systems,especially for repairing or increasing the photosynthesis activity of the plants grown under stress environment. | Kun Lu Danlei Shen Shipeng Dong Chunying Chen Sijie Lin Shan Lu Baoshan Xing Liang Mao | 2020 | Nano Research2020，13，12： | 4 |
| 5 | Efficient antimicrobial properties of layered double hydroxide assembled with transition metals via a facile preparation method显示文摘Mg2+in MgAl-layered double hydroxides nanoparticles was substituted with different divalent transition metal ions(MAl-LDHs,M:Mg2+,Cu2+,Ni2+,Co2+,and Mn2+)via a facile method to be used as antibacterial agents.The phase structural and morphological characterizations of MAl-LDHs were investigated by XRD,FTIR spectroscopy and TEM.The results have shown that all of MAl-LDHs had typical layered structures except MnAl-LDH which contained Mn304 phases.Particular morphology of MnAl-LDH with ellipsoids,spherical and rod-like structure and CuAl-LDH with rod-like shape existed.IC50(the concentrations providing 50%antibacterial activity)values of CuAl-LDH,NiAl-LDH,CoAl-LDH,and MnAlLDH in broth dilution tests were^800-1500μg/mL.Dosages of CuAl-LDH,CoAl-LDH,and MnAl-LDH with>10 mm inhibition zone in disk diffusion tests were^150-300μg/disk.Antibacterial mechanism of MAl-LDHs may be attributed to the synergistic factors including effected surroundings,surface interactions,morphology of particles,ROS and metal ions.The results indicate a facile method to synthesis LDHs based effective antibacterial agents with the potential application in the area of water treatment and antibacterial coating. | Mengxue Li Li Li Sijie Lin | 2020 | Chinese Chemical Letters2020，31，6： | 2 |
| 6 | Optimization of the OCO-2 Cloud Screening Algorithm and Evaluation against MODIS and TCCON Measurements over Land Surfaces in Europe and Japan显示文摘A method to tighten the cloud screening thresholds based on local conditions is used to provide more stringent schemes for Orbiting Carbon Observatory-2(OCO-2)cloud screening algorithms.Cloud screening strategies are essential to remove scenes with significant cloud and/or aerosol contamination from OCO-2 observations,which helps to save on the data processing cost and ensure high quality retrievals of the column-averaged CO2 dry air mole fraction(XCO2).Based on the radiance measurements in the 0.76μm O2A band,1.61μm(weak),and 2.06μm(strong)CO2 bands,the current combination of the A-Band Preprocessor(ABP)algorithm and Iterative Maximum A Posteriori(IMAP)Differential Optical Absorption Spectroscopy(DOAS)Preprocessor(IDP)algorithm passes around 20%-25%of all soundings,which means that some contaminated scenes also pass the screening process.In this work,three independent pairs of threshold parameters used in the ABP and IDP algorithms are sufficiently tuned until the overall pass rate is close to the monthly clear-sky fraction from the MODIS cloud mask.The tightened thresholds are applied to observations over land surfaces in Europe and Japan in 2016.The results show improvement of agreement and positive predictive value compared to the collocated MODIS cloud mask,especially in summer and fall.In addition,analysis indicates that XCO2 retrievals with more stringent thresholds are in closer agreement with measurements from collocated Total Carbon Column Observing Network(TCCON)sites. | Sijie CHEN Shuaibo WANG Lin SU Changzhe DONG Ju KE Zhuofan ZHENG Chonghui CHENG Bowen TONG Dong LIU | 2020 | Advances in Atmospheric Sciences2020，37，4： | 1 |
| 7 | Dynamics of synthetic yeast chromosome evolution shaped by hierarchical chromatin organization显示文摘Synthetic genome evolution provides a dynamic approach for systematically and straightforwardly exploring evolutionary processes.Synthetic Chromosome Rearrangement and Modification by LoxP-mediated Evolution(SCRaMbLE)is an evolutionary system intrinsic to the synthetic yeast genome that can rapidly drive structural variations.Here,we detect over 260000 rearrangement events after the SCRaMbLEing of a yeast strain harboring 5.5 synthetic yeast chromosomes(synⅡ,synⅢ,synⅤ,circular synⅥ,synⅨR and synⅩ).Remarkably,we find that the rearrangement events exhibit a specific landscape of frequency.We further reveal that the landscape is shaped by the combined effects of chromatin accessibili and spatial contact probability.The rearrangements tend to occur in 3D spatially proximal and chromatin-accessible regions.The enormous numbers of rearrangements mediated by SCRaMbLE provide a driving force to potentiate directed genome evolution,and the investigation of the rearrangement landscape offers mechanistic insights into the dynamics of genome evolution. | Sijie Zhou Yi Wu Yu Zhao Zhen Zhang Limin Jiang Lin Liu Yan Zhang Jijun Tang Ying-Jin Yuan | 2023 | National Science Review2023，10，5： | 1 |
| 8 | Mechanisms of Pb(Ⅱ) coprecipitation with natrojarosite and its behavior during acid dissolution显示文摘Lead(Pb) coprecipitation with jarosite is common in natural and engineered environments,such as acid mine drainage(AMD) sites and hydrometallurgical industry. Despite the high relevance for environmental impact, few studies have examined the exact interaction of Pb with jarosite and the dissolution behavior of each phase. In the present work, we demonstrate that Pb mainly interacts with jarosite in four modes, namely incorporation, occlusion,physically mixing, and chemically mixing. For comparison, the four modes of Pb-bearing natrojarosite were synthesized and characterized separately. Batch dissolution experiments were undertaken on these synthetic Pb-bearing natrojarosites under pH_(2) to simulate the AMD environments. The introduction of Pb decreases the final Fe releasing efficiency of jarosite-type compounds from 18.18% to 3.45%-5.01%, showing a remarkable inhibition of their dissolution. For Pb releasing behavior, PbSO_(4) dissolves in preference to Pb-substituted natrojarosite, i.e.,(Na, Pb)-jarosite, which primarily results in the sharp increase of Pb releasing concentration(> 40 mg/L). PbSO_(4) occlusion by jarosite-type compounds can significantly reduce the release of Pb. The results of this study could provide useful information regarding Fe and Pb cycling in acidic natural and engineered environments. | Meiqing Shi Xiaobo Min Chen Tian Taixu Hao Sijie Zhu Yun Ge Qingwei Wang Xu Yan Zhang Lin | 2022 | Journal of Environmental Sciences2022，34，12： | 1 |

| 10 | Physical and toxicological profiles of human IAPP amyloids and plaques显示文摘Although much has been learned about the fibrillization kinetics, structure and toxicity of amyloid proteins, the properties of amyloid fibrils beyond the saturation phase are often perceived as chemically and biologically inert, despite evidence suggesting otherwise. To fill this knowledge gap, we examined the physical and biological characteristics of human islet amyloid polypeptide(IAPP) fibrils that were aged up to two months. Not only did aging decrease the toxicity of IAPP fibrils, but the fibrils also sequestered fresh IAPP and suppressed their toxicity in an embryonic zebrafish model. The mechanical properties of IAPP fibrils in different aging stages were probed by atomic force microscopy and sonication, which displayed comparable stiffness but age-dependent fragmentation, followed by self-assembly of such fragments into the largest lamellar amyloid structures reported to date. The dynamic structural and toxicity profiles of amyloid fibrils and plaques suggest that they play active, long-term roles in cell degeneration and may be a therapeutic target for amyloid diseases. | Aleksandr Kakinen Yunxiang Sun Ibrahim Javed Ava Faridi Emily H.Pilkington Pouya Faridi Anthony W.Purcell Ruhong Zhou Feng Ding Sijie Lin Pu Chun Ke Thomas P.Davis | 2019 | Science Bulletin2019，64，1： | 0 |
| 11 | Prognostic value of the 21-gene recurrence score in ER-positive,HER2-negative,node-positive breast cancer was similar in nodenegative diseases:a single-center study of 800 patients显示文摘Multi-gene assays have emerged as crucial tools for risk stratification in early-stage breast cancer.This study aimed to evaluate the prognostic significance of the 21-gene recurrence score(RS)in Chinese patients with pN0-l,estrogen receptor-positive(ER+),human epidermal growth factor receptor 2-negative(HER2)breast cancer.Among 800 patients recruited between 2009 and 2016,the median RS was 24(0-69),with 27.4%,46.8%,and 25.9%patients classified into low-,intermediate-,and high-risk groups.Cox regression analysis demonstrated that the high-risk category was associated with significantly higher odds of invasive disease-free survival(IDFS)and distant disease-free survival(DDFS)events compared with the low-risk category(IDFS:HR=2.450,95%Cl 1.017-5.902,P=0.046;DDFS:HR=2.829,95%Cl 1.013-7.901,P=0.047).No significant association between RS category and overall survival(OS)was found(intermediate vs.low:HR=1.244,95%Cl 0.292-5.297,P=0.768;high vs.low:HR=2.933,95%Cl 0.759-11.327,P=0.119).RS,as a continuous variable,was a highly significant predictor for IDFS(HR=1.028,95%Cl 1.010-1.047,P=0.002),DDFS(HR=1.030,95%Cl 1.010-1.051,P=0.003),and OS(HR=1.034,95%Cl 1.007-1.063,P=0.014).Our findings suggested that RS may predict IDFS in Chinese patients with ER+/HER2 breast cancer with NO or N1 disease. | Jiayi Wu Weiqi Gao Xiaosong Chen Chunxiao Fei Lin Lin Weiguo Chen Ou Huang Siji Zhu Jianrong He Yafen Li Li Zhu Kunwei Shen | 2021 | Frontiers of Medicine2021，15，4： | 0 |

| 13 | Tetracycline sensitizes TiO_(2) for visible light photocatalytic degradation via ligand-to-metal charge transfer显示文摘Treatment of antibiotics contaminated water remains a global environmental challenge.In this study,tetracycline(TC)was found to effectively sensitize pure TiO_(2) for visible light photocatalytic degradation via a ligand-to-metal charge transfer mechanism.The sensitization was attributed to the formation of TC-TiO_(2) complex and the overlap of the molecular orbitals of TC and the conduction band of TiO_(2).The intermediate degradation products of TC,however,did not sensitize TiO_(2),which was the reason for the low mineralization rate.Nevertheless,our results showed that the intermediate degradation products of TC had significantly reduced bactericidal effects and less induction of antibiotic-resistance genes(ARGs).This study showcases an effective treatment of antibiotics-containing wastewater using the most common photocatalyst TiO_(2) with reduced risk in the spread of ARGs. | Caidie Qin Juanjuan Tang Ruxia Qiao Sijie Lin | 2022 | Chinese Chemical Letters2022，33，12： | 0 |
| 14 | Reductive lipid nanoparticles loaded with vinorelbine inhibit chemotherapy-induced invasion of cancer cells by modulating ENPP2显示文摘Cancer is a predominant culprit behind worldwide death and accounts for up to 10 million deaths every year.Chemotherapy is the primary therapeutic method employed for cancer in clinical settings and is essential in controlling tumor progression.Despite the advances in this field,tumor invasion and metastasis during treatment remain a significant cause of treatment failure.Nevertheless,the underlying mechanisms involving such a disappointing phenomenon are still not fully elucidated.Vinorelbine(VNB)extends the lifespan of many cancer patients in the clinic as an emerging chemotherapy drug approved by Food and Drug Administration(FDA).However,VNB-induced tumor metastasis is still an intractable problem,which may be closely related to the abnormal oxidative stress generated during VNB-mediated treatment.Hence,the study aims to construct a reductive nanosystem loaded with VNB,called VNB-VNP,to improve cancer cure rates and reduce tumor metastasis.With the reductive component vitamin E,VNB-VNP can effectively reduce oxidative stress and significantly outperform free VNB in preventing tumor progression.The transcriptome analysis shows that VNB-VNP can alleviate the over-expression of ectonucleotide pyrophosphatase/phosphodiesterase 2(ENPP2),which may be the main reason why VNB-VNP can inhibit tumor invasion and metastasis.Overall,the research designs a new platform for VNB treatment,which demonstrates promising efficacy in inhibiting neoplastic progression and identifies a new mechanism associated with VNB-induced tumor metastasis,which may offer several valuable references for enhancing chemotherapy efficacy in clinical anti-tumor therapy. | Xiaoqi Zhao Xuemeng Guo Mei Pang Weigen Qiu Zhenyu Luo Qing Lin Yichao Lu Hang Yin Sijie Wang Huihui Liu Junlei Zhang Lihua Luo Jian You | 2024 | Nano Research2024，17，4： | 0 |
| 15 | Synthesis of sponge-like TiO_(2) with surface-phase junctions for enhanced visible-light photocatalytic performance显示文摘Maximizing adsorption and catalytic active sites and promoting the photo-excited charge separation are two key factors to achieve excellent photocatalytic performance.In this study,we report a sol-gel synthesis approach to obtain non-metal doped TiO_(2)with sponge-like structure and surface-phase junctions all at once.While doping of carbon and nitrogen shifted the activation wavelength to the visible-light region,the innovative use of perchloric acid as a pore-making agent led to the formation of three-dimensional lamellar and porous structure with surface-phase junctions.High surface area with catalytic active sites rendered by the sponge-like structure and surface-phase junctions contributed to the much improved photocatalytic degradation efficiency toward rhodamine B,tetracycline and Disperse Red 60 with excellent reusability and stability.The improved gen eration and separati on efficie ncy of the photo-induced charge carriers of the as-prepared TiO_(2)were supported by electrochemical impedance measurements and transient photocurrent responses.This method could also be applied to other photocatalysts to achieve structural alteration and element doping simultaneously. | Yue Jiang Yao Qin Tianyu Yu Sijie Lin | 2021 | Chinese Chemical Letters2021，32，5： | 0 |
| 16 | Metallophilicity-Induced Clusterization:Single-Component White-Light Clusteroluminescence with Stimulus Response显示文摘Materials showing metallophilic interactions continue to attract considerable theoretical and experimental attention largely because of their unusual and unanticipated photophysical behavior as well as their unique stimuli-responsive behavior in an aggregate or solid state.Metallophilic interactions are mostly found between metals with either identical(d^(10)–d^(10))or different(s^(2)–d^(8),d^(8)–d^(10))configurations.Among various metallophilic interactions,aurophilic interactions(Au⋯Au)are well-known and widely reported.In this study,a new phosphorescent gold(I)complex,[(CF_(3)Ph)_(3)PAuC≡CPh](TPPGPA)was reported. | Xueqian Zhao Parvej Alam Jianyu Zhang Shiyun Lin Qian Peng Jun Zhang Guodong Liang Sijie Chen Jing Zhang Herman HYSung Jacky WYLam Ian DWilliams Xinggui Gu Zheng Zhao Ben Zhong Tang | 2022 | CCS Chemistry2022，4，8： | 0 |
| 17 | Regulatory Effect of JAK2/STAT3 on the Immune Function of Endotoxin-tolerant Dendritic Cells and its Involvement in Acute Liver Failure显示文摘Background and Aims:Acute liver failure(ALF)is a potentially fatal clinical syndrome with no effective treatment.This study aimed to explore the role of Janus kinase 2/signal transducer and activator of transcription 3(JAK2/STAT3)pathway in modulating the phenotype and immune function of endotoxin-tolerant dendritic cells(ETDCs).In addition,we explored the use of EDTCs in an experimental model of ALF and investigated the associated mechanisms.Methods:In the in vitro experiment,ETDCs were transfected with adenovirus to induce SOCS1^(+/+)ETDCs and SOCS1^(−/−)ETDCs.Thereafter,costimulatory molecules and mixed lymphocyte reaction were assessed.Experimental mice were randomly divided into normal control,ALF,ALF+mock-ETDCs,ALF+SOCS1^(+/+)ETDCs,ALF+AG490,and ALF+AG490+SOCS1^(+/+)ETDCs groups.We examined the therapeutic effect of adoptive cellular immunotherapy by tail-vein injection of target ETDCs 12 h before ALF modeling.AG490,a JAK2/STAT3 inhibitor,was used in the in vivo experiment to further explore the protective mechanism of SOCS1^(+/+)ETDCs.Results:Compared with control ETDCs,SOCS1^(+/+)ETDCs had lower expression of costimulatory molecules,weaker allostimulatory ability,lower levels of IL-6 and TNF-αexpression and higher IL-10 secretion.SOCS1^(−/−)ETDCs showed the opposite results.In the in vivo experiments,the ALF+SOCS1^(+/+)ETDCs and ALF+AG490+SOCS1^(+/+)ETDCs groups showed less pathological damage and suppressed activation of JAK2/STAT3 pathway.The changes were more pronounced in the ALF+AG490+SOCS1^(+/+)ETDCs group.Infusion of SOCS1^(+/+)ETDCs had a protective effect against ALF possibly via inhibition of JAK2 and STAT3 phosphorylation.Conclusions:The SOCS1 gene had an important role in induction of endotoxin tolerance.SOCS1^(+/+)ETDCs alleviated lipopolysaccharide/D-galactosamine-induced ALF by downregulating the JAK2/STAT3 signaling pathway. | Yukai Chen Chaochen Hou Naibin Yang Yanyan Yang Youran Chen Deyong Kong Yuchun Jiang Minghao Lin Sijie Zheng Shanshan Li Mingqin Lu | 2022 | Journal of Clinical and Translational Hepatology2022，10，5： | 0 |
| 18 | Doping Gd^(3+)Ion in PDA-PHBV Coating on Ti6Al4V Alloy for Enhancing Corrosion Resistance and Proliferation of Human Gingival Fibroblasts and Human Umbilical Vein Endothelial Cells显示文摘In this study,we fabricated poly(3-hydroxybutyrate-3-hydroxyvalerate)(PHBV)coatings doped with Gd^(3+)(1,5,and 10×10^(−4) mol/L)on Ti6Al4V alloy for the first time to promote soft tissue sealing around dental implants.The corrosion resistance of Gd^(3+)-modified PHBV-coated Ti6Al4V was studied by electrochemical and immersion tests,respectively,whereas CCK-8 and RT-PCR evaluated the biocompatibility to human gingival fibroblasts(HGFs)and human umbilical vein endothelial cells(HUVECs).It was found that the Gd^(3+)-modified PHBV coating could enhance the corrosion resistance of Ti6Al4V.In vitro cell tests showed that PHBV coatings with and without Gd^(3+) addition could promote adhesion and proliferation of HGFs and HUVECs,showing a Gd^(3+) content-dependent manner.Moreover,it was found that the PDA-PHBV@1Gd showed the best proliferation to HGFs by up-regulating gene expressions of VINCULIN,ITGB1,and ITGA3,whereas the best response to HUVECs with the highest gene expression of eNOS and HIF-1αgenes was found in the PDA-PHBV@5Gd-coated group. | Sijie Qin Xiongcheng Xu Yanjin Lu Liu Li Tingting Huang Jinxin Lin | 2022 | Acta Metallurgica Sinica(English Letters)2022，35，5： | 0 |
