| 1 | Recent progress in perovskite solar cells:material science显示文摘Perovskite solar cells represent a promising third-generation photovoltaic technology with low fabrication cost and high power conversion efficiency.In light of the rapid development of perovskite materials and devices,a systematic survey on the latest advancements covering a broad range of related work is urgently needed.This review summarizes the recent major advances in the research of perovskite solar cells from a material science perspective.The discussed topics include the devices based on different type of perovskites(organic-inorganic hybrid,all-inorganic,and lead-free perovskite and perovskite quantum dots),the properties of perovskite defects,different type of charge transport materials(organic,polymeric,and inorganic hole transport materials and inorganic and organic electron transport materials),counter electrodes,and interfacial materials used to improve the efficiency and stability of devices.Most discussions focus on the key progresses reported within the recent five years.Meanwhile,the major issues limiting the production of perovskite solar cells and the prospects for the future development of related materials are discussed. | Jiang-Yang Shao Dongmei Li Jiangjian Shi Chuang Ma Yousheng Wang Xiaomin Liu Xianyuan Jiang Mengmeng Hao Luozheng Zhang Chang Liu Yiting Jiang Zhenhan Wang Yu-Wu Zhong Shengzhong(Frank)Liu Yaohua Mai Yongsheng Liu Yixin Zhao Zhijun Ning Lianzhou Wang Baomin Xu Lei Meng Zuqiang Bian Ziyi Ge Xiaowei Zhan Jingbi You Yongfang Li Qingbo Meng | 2023 | Science China Chemistry2023，66，1： | 3 |
| 2 | Heterogeneity in endothelial cells and widespread venous arterialization during early vascular development in mammals显示文摘Arteriogenesis rather than unspecialized capillary expansion is critical for restoring effective circulation to compromised tissues in patients.Deciphering the origin and specification of arterial endothelial cells during embryonic development will shed light on the understanding of adult arteriogenesis.However,during early embryonic angiogenesis,the process of endothelial diversification and molecular events underlying arteriovenous fate settling remain largely unresolved in mammals.Here,we constructed the single-cell transcriptomic Iandscape of vascular endothelial cells(VECs)during the time window for the occurrenee of key vasculogenic and angiogenic events in both mouse and human embryos.We uncovered two distinct arterial VEC types,the major artery VECs and arterial plexus VECs,and un expectedly diverge nt arteriove nous characteristics among VECs that are located in morphologically undistinguishable vascular plexus intra-embryonically.Using computational prediction and further lineage tracing of venous-featured VECs with a newly developed Nr2f2^(CrexER) | Siyuan Hou Zongcheng Li Ji Dong Yun Gao Zhilin Chang Xiaochen Ding Shuaili Li Yunqiao Li Yang Zeng Qian Xin Baihan Wang Yanli Ni Xiaowei Ning Yuqiong Hu Xiaoying Fan Yu Hou Xianlong Li Lu Wen Bin Zhou Bing Liu Fuchou Tang Yu Lan | 2022 | Cell Research2022，32，4： | 2 |
| 3 | The microtubule aster formation and its role in nuclear envelope assembly around the sperm chromatin in Xenopus egg extracts显示文摘Nuclear envelope is a dynamic structure in the cell cycle. At the beginning of mitosis, nuclear envelope breaks down and its components disperse into the cytoplasm. At the end of mitosis, nuclear envelope reassembles using the dispersed components. Searching for the mechanisms of the nuclear disassembly and reassembly has for a long time been one of the key projects for cell biologists. In this report we show that microtubules take a role in the nuclear envelope assembly around the sperm chromatin in Xenopus egg ex-tracts. Microtubule cytoskeleton has been demonstrated to take roles in the transport of intracellular membranes such as Golgi and ER vesicles. We found that the nuclear envelope assembly needs functional microtubules. At the beginning of the nuclear assembly, microtubules nucleated to form a microtubule aster around the centrosome at the base of the sperm head. Using the microtubule drug colchicine to dis-rupt the microtubule nucleation, nuclear envelope reassem-bly was seriously inhibited. If the microtubules were stabi-lized by taxol, another microtubule drug, the nuclear enve-lope reassembly was also interfered, although a significantly large aster formed around the chromatin. Based on these observations, we propose that microtubules play an impor-tant role in the nuclear envelope reassembly maybe by transporting the nuclear envelope precursors to the chroma-tin surfaces. | YANG Ning CHEN Zhongcai LU Ping ZHANG Chuanmao ZHAI Zhonghe TANG Xiaowei | 2003 | Chinese Science Bulletin2003，48，18： | 2 |

| 6 | Embryonic lineage tracing with Procr-CreER marks balanced hematopoietic stem cell fate during entire mouse lifespan显示文摘The functional heterogeneity of hematopoietic stem cells(HSCs) has been comprehensively investigated by single-cell transplantation assay.However,the heterogeneity regarding their physiological contribution remains an open question,especially for those with life-long hematopoietic fate of rigorous selfrenewing and balanced differentiation capacities.In this study,we revealed that Procr expression was detected principally in phenotypical vascular endothelium co-expressing DII4 and CD44 in the midgestation mouse embryos,and could enrich all the HSCs of the embryonic day 11.5(E11.5) aortagonad-mesonephros(AGM) region.We then used a temporally restricted genetic tracing strategy to irreversibly label the Procr-exp res sing cells at E9.5.Interestingly,most labeled mature HSCs in multiple sites(such as AGM) around E11.5 were functionally categorized as lymphomyeloid-balanced HSCs assessed by direct transplantation.Furthermore,the labeled cells contributed to an average of 7.8% of immunophenotypically defined HSCs in E14.5 fetal liver(FL) and 6.9% of leukocytes in peripheral blood(PB) during one-year follow-up.Surprisingly,in aged mice of 24 months,the embryonically tagged cells displayed constant contribution to leukocytes with no bias to myeloid or lymphoid lineages.Altogether,we demonstrated,for the first time,the existence of a subtype of physiologically long-lived balanced HSCs as hypothesized,whose precise embryonic origin and molecular identity await further characterization. | Xiaona Zheng Guangyu Zhang Yandong Gong Xiaowei Ning Zhijie Bai Jian He Fan Zhou Yanli Ni Yu Lan Bing Liu | 2019 | Journal of Genetics and Genomics2019，46，10： | 1 |
| 7 | Coexistence of situs inversus totalis and hepatocellular carcinoma:A series of nine cases and a literature review显示文摘Hepatocellular carcinoma(HCC)is the most commonly diagnosed carcinoma and one of the leading causes of cancer-related deaths worldwide.Situs inversus totalis(SIT)is a congenital condition where in the internal organs of the abdomen and thorax lie in mirror images of their normal position.Thus far,there are very few reports on cases of SIT coexisting with HCC.Our case series is probably the largest series in world literature.The cohort of this retrospective study included a total of nine patients diagnosed with SIT-HCC and treated in our hospital between January 2013 and May 2018.Clinical characteristics,prognostic factors,and outcomes were summarized.Treatment strategies included surgery,transarterial chemoembolization,and microwave ablation.The diagnosis and treatment of patients with SIT are challenging because of organ reversion.The current treatment strategies for different stages of liver cancer are safe and feasible for patients with SIT-HCC. | Xiaowei Li Zhigang Fu Jiaming Zhong Kunkun Cao Xiaoxia Chen Ning Ding Li Liu Jian Zhai Zengqiang Qu | 2022 | Journal of Interventional Medicine2022，5，1： | 1 |

| 10 | Silicon-substituted rhodamines for stimulated emission depletion fluorescence nanoscopy显示文摘As an essential part in the toolbox of super-resolution microscopy,stimulated emission depletion(STED)nanoscopy has been widely explored in revealing the substructure and bioactivities in fluorescence imaging.Among the applied STED fluorophores,silicon-substituted rhodamines(SiRs)belong to one of the most extensively employed fluorophores.The carboxy-SiR was favored in STED bioimaging with many advantages,including reliable photostability,cell permeability,tunable fluorogenicity,feasible structural decoration and so on.We reviewed the research of carboxy-SiR in the STED nanoscopy and hopefully this can inspire more efforts in the design and application of STED fluorophores. | Ning Wang Yumeng Hao Xiaowei Feng Haidan Zhu Dazhi Zhang Ting Wang Xiaoyan Cui | 2022 | Chinese Chemical Letters2022，33，1： | 0 |
| 11 | Feasibility and physics potential of detecting ^(8)B solar neutrinos at JUNO显示文摘The Jiangmen Underground Neutrino Observatory(JUNO)features a 20 kt multi-purpose underground liquid scintillator sphere as its main detector.Some of JUNO's features make it an excellent location for^8B solar neutrino measurements,such as its low-energy threshold,high energy resolution compared with water Cherenkov detectors,and much larger target mass compared with previous liquid scintillator detectors.In this paper,we present a comprehensive assessment of JUNO's potential for detecting^8B solar neutrinos via the neutrino-electron elastic scattering process.A reduced 2 MeV threshold for the recoil electron energy is found to be achievable,assuming that the intrinsic radioactive background^(238)U and^(232)Th in the liquid scintillator can be controlled to 10^(-17)g/g.With ten years of data acquisition,approximately 60,000 signal and 30,000 background events are expected.This large sample will enable an examination of the distortion of the recoil electron spectrum that is dominated by the neutrino flavor transformation in the dense solar matter,which will shed new light on the inconsistency between the measured electron spectra and the predictions of the standard three-flavor neutrino oscillation framework.IfDelta m^(2)_(21)=4.8times10^(-5);(7.5times10^(-5))eV^(2),JUNO can provide evidence of neutrino oscillation in the Earth at approximately the 3sigma(2sigma)level by measuring the non-zero signal rate variation with respect to the solar zenith angle.Moreover,JUNO can simultaneously measureDelta m^2_(21)using^8B solar neutrinos to a precision of 20% or better,depending on the central value,and to sub-percent precision using reactor antineutrinos.A comparison of these two measurements from the same detector will help understand the current mild inconsistency between the value of Delta m^2_(21)reported by solar neutrino experiments and the KamLAND experiment.

| 12 | Pollen-Inspired Photonic Barcodes with Prickly Surface for Multiplex Exosome Capturing and Screening显示文摘Exosomes,which play an important role in intercellular communication,are closely related to the pathogenesis of disease.However,their effective capture and multiplex screening are still challenging.Here,inspired by the unique structure of pollens,we present novel photonic crystal(PhC)barcodes with prickly surface by hydrothermal synthesis for multiplex exosome capturing and screening.These pollen-inspired PhC barcodes are imparted with extremely high specific surface area and excellent prickly surface nanostructures,which can improve the capture rate and detection sensitivity of exosomes.As the internal periodic structures are kept during the hydrothermal synthesis process,the pollen-inspired PhC barcodes exhibit obvious and stable structural colors for identification,which enables multiplex detection of exosomes.Thus,the pollen-inspired PhC barcodes can not only effectively capture and enrich cancer-related exosomes but also support multiplex screening of exosomes with high sensitivity.These features make the prickly PhC barcodes ideal for the analysis of exosomes in medical diagnosis. | Ning Li Feika Bian Xiaowei Wei Lijun Cai Hongcheng Guu Yuanjin Zhao Luoran Shang | 2023 | Research2023，，1： | 0 |

| 14 | Regulation of osteoblast functions on titanium surfaces with different micro/nanotopographies and compositions显示文摘Surface modification of medical implants is considered as an effective method to improve cellular behaviors and the integration of tissues with materials. Titanium(Ti)-based materials with four different micro/nano-structures and compositions were prepared by acid etching, electrochemical anodization and alkali-heat treatment. The surface morphologies and compositions of the different surface-modified Ti materials were characterized by field-emission scanning electron microscopy(FE-SEM),atomic force microscopy(AFM) and X-ray diffraction(XRD). The effects of the micro/nano structured and compositions of the surfaces on cellular responses were investigated in vitro by observing the morphology, adhesion, proliferation and osteogenic differentiation of osteoblasts. To further investigate the underlying mechanisms, an RT-PCR assay was performed to analyze the expression levels of cell adhesion-related genes. Our results indicated that the nanosized structure and anatase composition could promote the adhesion and proliferation of MC3T3-E1 pre-osteoblast, as well as alkaline phosphatase activity and extracellular matrix mineralization via the integrin-FAK signaling pathway. Taken together, our innovation presented in this work demonstrated that the surface nano-structure design and composition of biomedical implants can be modified of for future orthopaedic applications. | HE Peng WANG XiaoLan NING ChengYun LIU XiaoWei LI Mei XU HaiDong GUO GuoDong MAO GuangPing LIU Gang XU Bin ZHANG Yu ZHAO JianNing | 2019 | Science China(Technological Sciences)2019，62，4： | 0 |
| 15 | Evaluation of immunoprotection against coronavirus disease 2019:Novel variants,vaccine inoculation,and complications显示文摘The strikingly rapidly mutating nature of the severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)genome has been a constant challenge during the coronavirus disease 2019(COVID-19)pandemic.In this study,various techniques,including reverse transcription-quantitative polymerase chain reaction,antigen-detection rapid diagnostic tests,and high-throughput sequencing were analyzed under different scenarios and spectra for the etiological diagnosis of COVID-19 at the population scale.This study aimed to summarize the latest research progress and provide up-to-date understanding of the methodology used for the evaluation of the immunoprotection conditions against future variants of SARS-CoV-2.Our novel work reviewed the current methods for the evaluation of the immunoprotection status of a specific population(endogenous antibodies)before and after vaccine inoculation(administered with biopharmaceutical antibody products).The present knowledge of the immunoprotection status regarding the COVID-19 complications was also discussed.Knowledge on the immunoprotection status of specific populations can help guide the design of pharmaceutical antibody products,inform practice guidelines,and develop national regulations with respect to the timing of and need for extra rounds of vaccine boosters. | Congshan Jiang Kaichong Jiang Xiaowei Li Ning Zhang Wenhua Zhu Liesu Meng Yanmin Zhang Shemin Lu | 2023 | Journal of Pharmaceutical Analysis2023，13，1： | 0 |
| 16 | Divergent expression of Neurl3 from hemogenic endothelial cells to hematopoietic stem progenitor cells during development显示文摘Prior to the generation of hematopoietic stem cells(HSCs)from the hemogenic endothelial cells(HECs)mainly in the dorsal aorta in midgestational mouse embryos,multiple hematopoietic progenitors including erythro-myeloid progenitors and lymphoid progenitors are generated from yolk sac HECs.These HSCindependent hematopoietic progenitors have recently been identified as major contributors to functional blood cell production until birth.However,little is known about yolk sac HECs.Here,combining integrative analyses of multiple single-cell RNA-sequencing datasets and functional assays,we reveal that Neurl3-EGFP,in addition to marking the continuum throughout the ontogeny of HSCs from HECs,can also serve as a single enrichment marker for yolk sac HECs.Moreover,while yolk sac HECs have much weaker arterial characteristics than either arterial endothelial cells in the yolk sac or HECs within the embryo proper,the lymphoid potential of yolk sac HECs is largely confined to the arterial-biased subpopulation featured by the Unc5b expression.Interestingly,the B lymphoid potential of hematopoietic progenitors,but not for myeloid potentials,is exclusively detected in Neurl3-negative subpopulations in midgestational embryos.Taken together,these findings enhance our understanding of blood birth from yolk sac HECs and provide theoretical basis and candidate reporters for monitoring step-wise hematopoietic differentiation. | Xiaowei Ning Junjie Du Yandong Gong Yingpeng Yao Zhijie Bai Yanli Ni Yanyan Li Zongcheng Li Haixin Zhao Jie Zhou Bing Liu Yu Lan Siyuan Hou | 2023 | Journal of Genetics and Genomics2023，50，9： | 0 |
