| 1 | Management of cytokine release syndrome related to CAR-T cell therapy显示文摘Chimeric antigen receptor T (CAR-T) cell therapy is a novel cellular immunotherapy that is widely used to treat hematological malignancies, including acute leukemia, lymphoma, and multiple myeloma. Despite its remarkable clinical effects, this therapy has side effects that cannot be underestimated. Cytokine release syndrome (CRS) is one of the most clinically important and potentially life-threatening toxicities. This syndrome is a systemic immune storm that involves the mass cytokines releasing by activated immune cells. This phenomenon causes multisystem damages and sometimes even death. In this study, we reported the management of a patient with recurrent and refractory multiple myeloma and three patients with acute lymphocytic leukemia who suffered CRS during CAR-T treatment. The early application of tocilizumab, an anti-IL-6 receptor antibody, according to toxicity grading and clinical manifestation is recommended especially for patients who suffer continuous hyperpyrexia, hypotensive shock, acute respiratory failure, and whose CRS toxicities deteriorated rapidly. Moreover, low doses of dexamethasone (5-10 mg/day) were used for refractory CRS not responding to tocilizumab. The effective management of the toxicities associated with CRS will bring additional survival opportunities and improve the quality of life for patients with cancer. | Hongli Chen Fangxia Wang Pengyu Zhang Yilin Zhang Yinxia Chen Xiaohu Fan Xingmei Cao Jie Liu Yun Yang Baiyan Wang Bo Lei Liufang Gu Ju Bai Lili Wei Ruili Zhang Qiuchuan Zhuang Wanggang Zhang Wanhong Zhao Aili He | 2019 | Frontiers of Medicine2019，13，5： | 21 |
| 2 | Design of high efficiency achromatic metalens with large operation bandwidth using bilayer architecture显示文摘Achromatic metalens composed of arrays of subwavelength nanostructures with spatially varying geometries is attractivefor a number of optical applications. However, the limited degree of freedom in the single layer achromatic metasurfacedesign makes it difficult to simultaneously guarantee the sufficient phase dispersion and high diffraction efficiency,which restricts the achromatic bandwidth and efficiency of metalens. Here we propose and demonstrate a high efficiencyachromatic metalens with diffraction-limited focusing capability at the wavelength ranging from 1000 nm to 1700 nm. Themetalens comprises two stacked nanopillar metasurfaces, by which the required focusing phase and dispersion compensationcan be controlled independently. As a result, in addition to the large achromatic bandwidth, the averaged focusingefficiency of the bilayer metalens is higher than 64% at the near-infrared region. Our design opens up the possibilityto obtain the required phase dispersion and efficiency simultaneously, which is of great significance to design broadbandmetasurface-based optical devices. | Yilin Wang Qingbin Fan Ting Xu | 2021 | Opto-Electronic Advances2021，4，1： | 17 |
| 3 | Comparative genomic and transcriptomic analyses uncover the molecular basis of high nitrogen-use efficiency in the wheat cultivar Kenong 9204显示文摘Studying the regulatory mechanisms that drive nitrogen-use efficiency(NUE)in crops is important for sustainable agriculture and environmental protection.In this study,we generated a high-quality genome assembly for the high-NUE wheat cultivar Kenong 9204 and systematically analyzed genes related to nitrogen uptake and metabolism.By comparative analyses,we found that the high-affinity nitrate transporter gene family had expanded in Triticeae.Further studies showed that subsequent functional differentiation endowed the expanded family members with saline inducibility,providing a genetic basis for improving the adaptability of wheat to nitrogen deficiency in various habitats.To explore the genetic and molecular mechanisms of high NUE,we compared genomic and transcriptomic data from the high-NUE cultivar Kenong 9204(KN9204)and the low-NUE cultivar Jing 411 and quantified their nitrogen accumulation under high-and low-nitrogen conditions.Compared with Jing 411,KN9204 absorbed significantly more nitrogen at the reproductive stage after shooting and accumulated it in the shoots and seeds.Transcriptome data analysis revealed that nitrogen deficiency clearly suppressed the expression of genes related to cell division in the young spike of Jing 411,whereas this suppression of gene expression was much lower in KN9204.In addition,KN9204 maintained relatively high expression of NPF genes for a longer time than Jing 411 during seed maturity.Physiological and transcriptome data revealed that KN9204 was more tolerant of nitrogen deficiency than Jing 411,especially at the reproductive stage.The high NUE of KN9204 is an integrated effect controlled at different levels.Taken together,our data provide new insights into the molecular mechanisms of NUE and important gene resources for improving wheat cultivars with a higher NUE trait. | Xiaoli Shi Fa Cui Xinyin Han Yilin He Long Zhao Na Zhang Hao Zhang Haidong Zhu Zhexin Liu Bin Ma Shusong Zheng Wei Zhang Jiajia Liu Xiaoli Fan Yaoqi Si Shuiquan Tian Jianqing Niu Huilan Wu Xuemei Liu Zhuo Chen Deyuan Meng Xiaoyan Wang Liqiang Song Lijing Sun Jie Han Hui Zhao Jun Ji Zhiguo Wang Xiaoyu He Ruilin Li Xuebin Chi Chengzhi Liang Beifang Niu Jun Xiao Junming Li Hong-Qing Ling | 2022 | Molecular Plant2022，15，9： | 6 |

| 5 | Substantial transition to clean household energy mix in rural China显示文摘The household energy mix has significant impacts on human health and climate,as it contributes greatly to many health-and climate-relevant air pollutants.Compared to the well-established urban energy statistical system,the rural household energy statistical system is incomplete and is often associated with high biases.Via a nationwide investigation,this study revealed high contributions to energy supply from coal and biomass fuels in the rural household energy sector,while electricity comprised∼20%.Stacking(the use of multiple sources of energy)is significant,and the average number of energy types was 2.8 per household.Compared to 2012,the consumption of biomass and coals in 2017 decreased by 45%and 12%,respectively,while the gas consumption amount increased by 204%.Increased gas and decreased coal consumptions were mainly in cooking,while decreased biomass was in both cooking(41%)and heating(59%).The time-sharing fraction of electricity and gases(E&G)for daily cooking grew,reaching 69%in 2017,but for space heating,traditional solid fuels were still dominant,with the national average shared fraction of E&G being only 20%.The non-uniform spatial distribution and the non-linear increase in the fraction of E&G indicated challenges to achieving universal access to modern cooking energy by 2030,particularly in less-developed rural and mountainous areas.In some non-typical heating zones,the increased share of E&G for heating was significant and largely driven by income growth,but in typical heating zones,the time-sharing fraction was<5%and was not significantly increased,except in areas with policy intervention.The intervention policy not only led to dramatic increases in the clean energy fraction for heating but also accelerated the clean cooking transition.Higher income,higher education,younger age,less energy/stove stacking and smaller family size positively impacted the clean energy transition. | Guofeng Shen Rui Xiong Yanlin Tian Zhihan Luo Bahabaike Jiangtulu Wenjun Meng Wei Du Jing Meng Yuanchen Chen Bing Xue Bin Wang Yonghong Duan Jia Duo Fenggui Fan Lei Huang Tianzhen Ju Fenggui Liu Shunxin Li Xianli Liu Yungui Li Mu Wang Ying Nan Bo Pan Yanfang Pan Lizhi Wang Eddy Zeng Chao Zhan Yilin Chen Huizhong Shen Hefa Cheng Shu Tao | 2022 | National Science Review2022，9，7： | 4 |
| 6 | Unloading performances and stabilizing practices for columnar jointed basalt:A case study of Baihetan hydropower station显示文摘The columnar jointed rock mass(CJR), composed of polygonal cross-sectional columns cut by several groups of joints in various directions, was exposed during the excavations of the Baihetan hydropower station, China. In order to investigate the unloading performances and the stability conditions during excavation of the columns, an experimental field study was performed. Firstly, on-site investigations indicated that the geotechnical problems, including rock relaxation, cracking and collapse, were the most prominent for the CJR Class I that contains intensive joint network and the smallest column sizes.Comprehensive field tests, including deformation measurement by multi-point extensometers, ultrasonic wave testing, borehole television observation and stress monitoring of rock anchors, revealed that the time-dependent relaxation of the CJRs was marked. The practical excavation experiences for the Baihetan columnar jointed rock masses, such as blasting scheme, supporting time of shotcrete and rock bolts, were presented in the excavations of the diversion tunnels. These detailed investigations and practical construction experiences can provide helpful information for similar geotechnical works in jointed rock mass. | Qixiang Fan Xiating Feng Wenlin Weng Yilin Fan Quan Jiang | 2017 | Journal of Rock Mechanics and Geotechnical Engineering2017，9，6： | 4 |
| 7 | Direct observation of chaotic resonances in optical microcavities显示文摘Optical microcavities play a significant role in the study of classical and quantum chaos.To date,most experimental explorations of their internal wave dynamics have focused on the properties of their inputs and outputs,without directly interrogating the dynamics and the associated mode patterns inside.As a result,this key information is rarely retrieved with certainty,which significantly restricts the verification and understanding of the actual chaotic motion.Here we demonstrate a simple and robust approach to directly and rapidly map the internal mode patterns in chaotic microcavities.By introducing a local index perturbation through a pump laser,we report a spectral response of optical microcavities that is proportional to the internal field distribution.With this technique,chaotic modes with staggered mode spacings can be distinguished.Consequently,a complete chaos assisted tunneling(CAT)and its time-reversed process are experimentally verified in the optical domain with unprecedented certainty. | Shuai Wang Shuai Liu Yilin Liu Shumin Xiao Zi Wang Yubin Fan Jiecai Han Li Ge Qinghai Song | 2021 | Light(Science & Applications)2021，10，8： | 3 |
| 8 | H_(2)S promotes developmental brain angiogenesis via the NOS/NO pathway in zebrafish显示文摘Background Hydrogen sulphide(H_(2)S)is considered as the third member of the gasotransmitter family,along with nitric oxide(NO)and carbon monoxide.H_(2)S has been reported to induce angiogenesis by promoting the growth,migration and tube-like structure formation of endothelial cells.Those studies were conducted in conditions of cell culture,mouse Matrigel plug assay model,rat wound healing model or rat hindlimb ischaemia model.Recent in vivo studies showed the physiological importance of H_(2)S in muscle angiogenesis.However,the importance of endogenous H_(2)S for brain angiogenesis during development remains unknown.We therefore aimed at determining the role of H_(2)S in brain vascular development.Methods and results Both knockdown and knockout of H2S-producing enzymes,cystathionineβ-synthase(cbs)and cystathionineγ-lyase(cth),using morpholino oligonucleotides and clustered regularly interspaced short palindromic repeats/Cas9-mediated mutation,impaired brain vascular development of larval zebrafish.Incubation with the slow-releasing H_(2)S donor GYY4137 alleviated the defects of brain vascular development in cbs and cth morphants.Quantitative analysis of the midbrain vascular network showed that H_(2)S enhances angiogenesis without affecting the topological structure of the brain vasculature.Mechanically,nitric oxide synthase 2a(nos2a)expression and NO production were decreased in both cbs and cth morphants.Overexpression of nos2a by coinjection of cbs or cth MO with full-length zebrafish nos2a mRNA alleviated the brain vascular developmental defects in cbs and cth morphants.Conclusion We conclude that H_(2)S promotes brain developmental angiogenesis via the NOS/NO pathway in zebrafish. | Weiqing Jiang Chen Liu Mingzhu Deng Fei Wang Xiao Ren Yilin Fan Jiulin Du Yonggang Wang | 2021 | Stroke & Vascular Neurology2021，6，2： | 2 |
| 9 | Green‑Solvent Processed Blade‑Coating Organic Solar Cells with an Efficiency Approaching 19%Enabled by Alkyl‑Tailored Acceptors显示文摘Power-conversion-efficiencies(PCEs)of organic solar cells(OSCs)in laboratory,normally processed by spin-coating technology with toxic halogenated solvents,have reached over 19%.However,there is usually a marked PCE drop when the bladecoating and/or green-solvents toward large-scale printing are used instead,which hampers the practical development of OSCs.Here,a new series of N-alkyl-tailored small molecule acceptors named YR-SeNF with a same molecular main backbone are developed by combining selenium-fused central-core and naphthalene-fused endgroup.Thanks to the N-alkyl engineering,NIR-absorbing YR-SeNF series show different crystallinity,packing patterns,and miscibility with polymeric donor.The studies exhibit that the molecular packing,crystallinity,and vertical distribution of active layer morphologies are well optimized by introducing newly designed guest acceptor associated with tailored N-alkyl chains,providing the improved charge transfer dynamics and stability for the PM6:L8-BO:YRSeNF-based OSCs.As a result,a record-high PCE approaching 19%is achieved in the blade-coating OSCs fabricated from a greensolvent o-xylene with high-boiling point.Notably,ternary OSCs offer robust operating stability under maximum-power-point tracking and well-keep>80%of the initial PCEs for even over 400 h.Our alkyl-tailored guest acceptor strategy provides a unique approach to develop green-solvent and blade-coating processed high-efficiency and operating stable OSCs,which paves a way for industrial development. | Hairui Bai Ruijie Ma Wenyan Su Top Archie Dela Pea Tengfei Li Lingxiao Tang Jie Yang Bin Hu Yilin Wang Zhaozhao Bi Yueling Su Qi Wei Qiang Wu Yuwei Duan Yuxiang Li Jiaying Wu Zicheng Ding Xunfan Liao Yinjuan Huang Chao Gao Guanghao Lu Mingjie Li Weiguo Zhu Gang Li Qunping Fan Wei Ma | 2023 | Nano-Micro Letters2023，15，12： | 1 |
| 10 | Semi-empirical estimation for enhancing negative thermal expansion in PbTiO_(3)-based perovskites显示文摘Generally,most materials expand when heated and contract when cooled,whereas negative thermal expansion(NTE)materials are very rare.As a typical NTE material,PbTiO_(3) and related compounds have drawn particular interest in recent years.The discovery of an enhanced NTE system in PbTiO_(3) is beneficial to deepen our understanding of its mechanism and regulate its properties.At present,the method of discriminating an enhanced NTE material based on PbTiO_(3) is not universal.Here,we propose a semi-empirical method through evaluating the average lattice distortion in related systems to estimate the relative coefficient of thermal expansion conveniently.The rationality of the method was verified by the analysis of the 0.6PbTiO_(3)-0.4Bi(Ga_(x)Fe_(1-x))O_(3) system.So far,all PbTiO_(3)-based compounds with enhanced NTE conform well to this method.This method provides the possibility to find more enhanced NTE PbTiO_(3)-based materials. | Tao Yang Longlong Fan Yilin Wang Kun Lin Jun Chen Xianran Xing | 2022 | International Journal of Minerals,Metallurgy and Materials2022，29，4： | 1 |

| 13 | Reinforcement learning based energy-efficient internet-of-things video transmission显示文摘The video transmission in the Internet-of-Things(IoT)system must guarantee the video quality and reduce the packet loss rate and the delay with limited resources to satisfy the requirement of multimedia services.In this paper,we propose a reinforcement learning based energy-efficient IoT video transmission scheme that protects against interference,in which the base station controls the transmission action of the IoT device including the encoding rate,the modulation and coding scheme,and the transmit power.A reinforcement learning algorithm state-action-reward-state-action is applied to choose the transmission action based on the observed state(the queue length of the buffer,the channel gain,the previous bit error rate,and the previous packet loss rate)without knowledge of the transmission channel model at the transmitter and the receiver.We also propose a deep reinforcement learning based energy-efficient IoT video transmission scheme that uses a deep neural network to approximate Q value to further accelerate the learning process involved in choosing the optimal transmission action and improve the video transmission performance.Moreover,both the performance bounds of the proposed schemes and the computational complexity are theoretically derived.Simulation results show that the proposed schemes can increase the peak signal-to-noise ratio and decrease the packet loss rate,the delay,and the energy consumption relative to the benchmark scheme. | Yilin Xiao Guohang Niu Liang Xiao Yuzhen Ding Sicong Liu Yexian Fan | 2020 | Intelligent and Converged Networks2020，1，3： | 0 |
| 14 | A breakthrough trial of an artificial liver without systemic heparinization in hyperbilirubinemia beagle models显示文摘The development of wearable artificial livers was restricted to device miniaturization and bleeding risk with water-soluble anticoagulants.Herein,a double-deck column filled with solid anticoagulant microspheres and Kevlar porous microspheres(KPMs,bilirubin adsorbents)was connected with the principle machine of wearable artificial liver(approximately 9 kg)to treat hyperbilirubinemia beagles for the first time.With the initial normal dose of heparin,the double-deck column could afford 3 h hemoperfusion in whole blood without thrombus formation.The removal efficiency of the double-deck column for total bilirubin(TBIL)was 31.4%.Interestingly,the excessive amounts of hepatocyte metabolites were also decreased by approximately 25%.The“anticoagulant+column”realized safe and effective whole blood hemoperfusion without the plasma separation system and heparin pump;however,the proposed principle machine of wearable artificial liver and“anticoagulant+column”cannot completely replace the bio-liver now.The intelligence of the device and the versatility of the adsorbent need to be improved;moreover,advanced experimental techniques need to be developed to validate the survival rates in animals.Overall,this study is a meaningful trial for the development of wearable artificial livers in the future. | Yilin Wang Shanshan Wang Xueqin He Yupei Li Tao Xu Lin Xu Bo Yang Xinnian Fan Weifeng Zhao Changsheng Zhao | 2023 | Bioactive Materials2023，，2： | 0 |
| 15 | Alkylation of benzene with carbon dioxide to low-carbon aromatic hydrocarbons over bifunctional Zn-Ti/HZSM-5 catalyst显示文摘Alkylation of benzene to value-added,high octane number and low toxic toluene and xylenes provides a way to lower benzene content in gasoline pool,and is hence a method to promote fuel quality.On the other hand,CO_(2) accumulation in the atmosphere causes global warming and requires effective route for its valorization.Utilization of CO_(2) as a carbon source for benzene alkylation could achieve both goals.Herein,alkylation of benzene with CO_(2) and H2 was realized by a series of low-cost bifunctional catalysts containing zinc/titanium oxides(Zn/Ti oxides)and HZSM-5 molecular sieves in a fixed-bed reactor.By regulating and controlling oxygen vacancies of Zn/Ti oxides and the acidities of HZSM-5,benzene conversion and CO_(2) conversion reached 28.7%and 29.9%respectively,along with a total selectivity of toluene and xylene higher than 90%.In this process,more than 25%CO_(2) was effectively utilized and incorporated into the target products.Moreover,the mechanism of the reaction was analyzed and the course was simultaneously traced.CO_(2) was transformed into methanol firstly,and then methanol reacted with benzene generating toluene and xylene.The innovation provides a new method for upgrading of fuels and upcycling the emissions of CO_(2),which is of great environmental and economic benefits. | Xiangyu Liu Yanling Pan Peng Zhang Yilin Wang Guohao Xu Zhaojie Su Xuedong Zhu Fan Yang | 2022 | Frontiers of Chemical Science and Engineering2022，16，3： | 0 |
| 16 | Revealing the intrinsic nonlinear optical response of a single MoS_(2) nanosheet in a suspension based on spatial self-phase modulation显示文摘The reorientation of 2D materials caused by nonlocal electron coherence is the formation mechanism of 2D material spatial self-phase modulation under laser irradiation,which is widely known as the“wind-chime”model.Here,we present a method that provides strong evidence for the reorientation of 2D-material-induced spatial self-phase modulation.The traditional“wind-chime”model was modified by taking into account the attenuation,i.e.,damping of the incident light beam in the direction of the optical path.Accordingly,we can extract the nonlinear refractive index of a single MoS2 nanosheet,instead of simply obtaining the index from an equivalent MoS2 film that was constructed by all nanosheets.Our approach introduces a universal and accurate method to extract intrinsic nonlinear optical parameters from 2D material systems. | Si Xiao Ying Ma Yilin He Yiduo Wang Hao Xin Qi Fan Jingdi Zhang Xiaohong Li Yu Zhang Jun He Yingwei Wang | 2020 | Photonics Research2020，8，11： | 0 |

| 18 | Pearling and helical nanostructures of model protocell membranes显示文摘The diversity of protocell membrane structures is crucial for the regulation of cell activities and indispensable to the origin of life.Prior to the evolution of complex cellular machinery,spontaneous protocell membrane evolution results from the intrinsic physicochemical properties of simple molecules under specific environmental conditions.Here,we report the evolution of the morphology of cell-sized model protocell membranes from giant vesicles to pearling and helical nanostructures,resembling morphologies of eukaryocytes,nostoc,and spirilla.This evolution occurs in a single binary aqueous system composed of an achiral single-chain amphiphile and a biogenic polyamine(spermidine or spermine)upon evaporating water,feeding amphiphiles,or increasing pH in response to various primitive fluctuating conditions.In contrast,nonbiogenic polyamines(triamine,triethylenetetramine,and hexamethyltriethylenetetramine)with slight differences in the number of methylene groups or protonated amine groups do not induce such a kind of evolution.The evolution of the shape transformation strongly relies on the balance between electrostatic attraction and hydrogen bonding,attributed to the odd/even effect of polyamines in the assembly.Strikingly,both pearling and helical structures emerge from multilamellar vesicles undergoing different processes,where the helix shows stronger permeability and encapsulation capability due to its multicompartmentalized structure.Thus,subtle adjustment of weak intramolecular interactions not only yields significant changes in the morphological evolution of protocell membranes but also brings new insights into the natural inevitability of biogenic small molecules. | Zhidi Chen Yaxun Fan Yao Chen Jeffrey Penfold Peixun Li Rongliang Wu Yilin Wang | 2022 | Nano Research2022，15，1： | 0 |
| 19 | VabHLH137 promotes proanthocyanidin and anthocyanin biosynthesis and enhances resistance to Colletotrichum gloeosporioides in grapevine显示文摘Proanthocyanidins(PAs)and anthocyanins are involved in the response of plants to various environmental stresses.However,the mechanism behind defense-induced PA biosynthetic regulation is still not completely elucidated,also in grapevine.This study performed a transcriptome sequencing analysis of grape berries infected with Colletotrichum gloeosporioides to highlight the induction of the VabHLH137 factor from the basic helix-loop-helix(bHLH)XII subfamily by the fungus,which appeared to be significantly co-expressedwith PA-related genes.The functional analysis of VabHLH137 overexpression and knockdownin transgenic grape calli showed that it positively regulated PA and anthocyanin biosynthesis.Moreover,VabHLH137 overexpression in the grape calli significantly increased resistance to C.gloeosporioides.A yeast one-hybrid and electrophoretic mobility shift assay revealed that VabHLH137 directly bound to the VaLAR2 promoter,enhancing its activity and interacting with VaMYBPAR,a transcriptional activator of PA biosynthesis.Furthermore,transient experiments showed that although the VabHLH137+VaMYBPAR complex activated VaLAR2 expression,it failed to further enhance VaLAR2 expression compared to VaMYBPAR alone.The findings indicated that VabHLH137 enhanced PA biosynthesis by activating of VaLAR2 expression,providing new insight into the transcriptional regulation of defense-induced PA biosynthesis in grapevine. | Dan Yu Wei Wei Zhongqi Fan Jianye Chen Yilin You Weidong Huang Jicheng Zhan | 2023 | Horticulture Research2023，10，2： | 0 |
| 20 | Grid cell remapping under three-dimensional object and social landmarks detected by implantable microelectrode arrays for the medial entorhinal cortex显示文摘Grid cells with stable hexagonal firing patterns in the medial entorhinal cortex(MEC)carry the vital function of serving as a metric for the surrounding environment.Whether this mechanism processes only spatial information or involves nonspatial information remains elusive.Here,we fabricated an MEC-shaped microelectrode array(MEA)to detect the variation in neural spikes and local field potentials of the MEC when rats forage in a square enclosure with a planar,three-dimensional object and social landmarks in sequence.The results showed that grid cells exhibited rate remapping under social conditions in which spike firing fields closer to the social landmark had a higher firing rate.Furthermore,global remapping showed that hexagonal firing patterns were rotated and scaled when the planar landmark was replaced with object and social landmarks.In addition,when grid cells were activated,the local field potentials were dominated by the theta band(5–8 Hz),and spike phase locking was observed at troughs of theta oscillations.Our results suggest the pattern separation mechanism of grid cells in which the spatial firing structure and firing rate respond to spatial and social information,respectively,which may provide new insights into how the brain creates a cognitive map. | Zhaojie Xu Fan Mo Gucheng Yang Penghui Fan Yiding Wang Botao Lu Jingyu Xie Yuchuan Dai Yilin Song Enhui He Shihong Xu Juntao Liu Mixia Wang Xinxia Cai | 2022 | Microsystems & Nanoengineering2022，8，5： | 0 |
