| 1 | Single-cell analysis reveals bronchoalveolar epithelial dysfunction in COVID-19 patients显示文摘Dear Editor,In 2019,a zoonotic coronavirus named severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)was identified as the causative agent of Coronavirus Disease 2019(COVID-19).As of 8 June 2020,the World Health Organization(WHO)has reported 6,912,751 globally confirmed cases with 400,469 deaths.Although generally causes mild disease,SARS-CoV-2 infection can result in serious outcomes,including acute lung injury(ALI)and acute respiratory distress syndrome(ARDS),the leading cause of mortality in patients with comorbidities.Recent autopsy studies of COVID-19 patients revealed mononuclear infiltration and excessive production of mucus in the infected lung,especially in the damaged small airways and alveoli(Bian and Team,2020;Liu et al.,2020). | Jiangping He Shuijiang Cai Huijian Feng Baomei Cai Lihui Lin Yuanbang Mai Yinqiang Fan Airu Zhu Huang Huang Junjie Shi Dingxin Li' Yuanjie Wei Yueping Li Yingying Zhao’ Yuejun Pan He Liu Xiaoneng Mo Xi He Shangtao Cao FengYu Hu Jincun Zhao Jie Wang Nanshan Zhong Xinwen Chen Xilong Deng Jiekai Chen | 2020 | Protein & Cell2020，11，9： | 7 |
| 2 | Expanding the scope of genome editing with SpG and SpRY variants in rice显示文摘Dear Editor,The clustered regularly interspaced short palindromic repeats/CRISPR-associated nuclease 9(CRISPR/Cas9)system,since it was excavated,has been rapidly developed and sparked a revolution in the genome editing field.In principle,CRISPR/Cas9 system relies on the recognition of specific loci on the genome,which is titled the protospacer adjacent motif(PAM).However,the canonical Streptococcus pyogenes Cas9(SpCas9)nuclease only recognizes NGG or NAG PAMs,rendering an inherent obstacle in amplifying the application of CRISPR/Cas9 technology. | Jun Ren Xiangbing Meng Fengyue Hu Qing Liu Yuexuan Cao Huiying Li Changjie Yan Jiayang Li Kejian Wang Hong Yu Chun Wang | 2021 | Science China(Life Sciences)2021，64，10： | 4 |
| 3 | Experimental Insights on the Structural Patterns and Their Formation Mechanisms of the Xujiaweizi Fault Depression in the Songliao Basin显示文摘The Xujiaweizi(XJWZ) fault depression is a primary area for deep-seated gas exploration in Daqing. Through seismic profile interpretation, the main sag-controlling fault and structural characteristics in the XJWZ fault depression were analyzed based on folds and faults analysis. A three-dimensional geological model of the XJWZ fault depression was also set up to enable further discussion by means of structural physical modeling. According to our research, the basic structural framework of the XJWZ fault depression was the result of regional extension. Its formation and evolution were mainly controlled by the Xuxi fault. The structural framework of S-N blocking was due to changes in the fracture attitude. The Xuzhong uplift and the depressions on both sides belong to a normal-fault-related fold and were formed by controlling of the ramp/flat normal fault in the same tectonic movement period. | Wei Long Zhongquan Li Ying Li Junliang Chen Fengyu Tan Zhiyi Zheng Jinmiao Hu Runfang Li | 2018 | Journal of Earth Science2018，29，2： | 3 |
| 4 | Characteristics of SARS-CoV-2 Delta variant-infected individuals with intermittently positive retest viral RNA after discharge显示文摘SARS-CoV-2-infected patients will be discharged when viral ribonucleic acid(RNA)is consecutively negative at least twice over a 24-h interval.However,we have demonstrated that positive retest viral RNA,a particular clinical phenomenon initially observed in discharged SARS-CoV-2-infected patients in early 2020[1,2],is the occasional reoccurrence of Polymerase Chain Reaction(PCR)-detectable viral RNA but not reinfection[3]. | Lu Li Jingyan Tang Zhiwei Xie Qingxin Gan Guofang Tang Zhongwei Hu Huimin Zeng Jingrong Shi Jiaojiao Li Yan Li Changwen Ke Min Kang Dan Liang Huan Lu Yuwei Tong Xilong Deng Jinxin Liu Hongzhou Lu Fuxiang Wang Fengyu Hu Feng Li Nanshan Zhong Xiaoping Tang | 2022 | National Science Review2022，9，10： | 3 |
| 5 | Significantly reduced abilities to cross-neutralize SARS-CoV-2 variants by sera from convalescent COVID-19 patients infected by Delta or early strains显示文摘The worldwide pandemic caused by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)has resulted in more than 4.5 million deaths.Although coronaviruses have a proofreading mechanism to maintain the stability of their long genomic RNAs,mutations emerge continuously,and new variants conferring advantages rapidly become the dominant lineages[1].Strategies to fight the COVID-19 pandemic using either vaccines or nonpharmaceutical interventions have specifically been threatened by the emergence of SARS-CoV-2 variants of concern(VOCs)[2]. | Ting Pan Zhongwei Hu Fengyu Hu Yiwen Zhang Bingfeng Liu Changwen Ke Qiumin She Xin He Xiaoping Tang Hui Zhang | 2021 | Cellular & Molecular Immunology2021，18，11： | 1 |

| 8 | Defective NH_(2)-UiO-66(Zr) effectively converting CO_(2) into cyclic carbonate under ambient pressure,solvent-free and co-catalyst-free conditions显示文摘In this study,a series of metal-organic frameworks(MOFs)NH_(2)-UiO-66-x HAc catalysts were synthesized by solvothermal method using acetic acid(HAc)as a modulator,and were applied to the cycloaddition of CO_(2)and epichlorohydrin(EPIC)under ambient pressure.Influences of the modulation by HAc on morphologies and structures of the MOFs are demonstrated via PXRD,FESEM,FTIR,N_(2)adsorption-desorption,XPS and ^(1)H NMR characterizations.The results show that the MOFs containing mesoporous pores can be prepared by adjusting the concentration of HAc.By optimizing the amount of HAc added,the specific surface area of NH_(2)-UiO-66-8 HAc is as high as 879.17 m^(2)·g^(-1),which is 28.3%higher than that of the original MOFs.And the evaluation of catalytic performance showed that HAc modulation enhanced the activity of NH_(2)-UiO-66-x HAc under mild conditions.The exposure of Lewis acid sites,increased specific surface area and porosity via the modulation of HAc defective ligand can be supposed the key factors to determine the enhanced catalytic activities.In addition,considering the influence of gas concentration on the reaction,the concept of TOP(Turnover of Pressure,defined as the mass of conversions of a unit mass catalyst under unit pressure and unit time)was first proposed in this article. | Xueting Liu Chunhui Hu Jingjing Wu Peng Cui Fengyu Wei | 2022 | Chinese Journal of Chemical Engineering2022，35，3： | 1 |

| 10 | Molecular phylogenomic analysis reveals a single origin of monkeypox virus transmission in Guangzhou,China in June 2023显示文摘The monkeypox(mpox)virus has caused worldwide transmission since its initial report in England in early May 2022.Available data from the World Health Organization(WHO)show that Europe and the Americas experienced a huge wave of mpox virus infection.Now the number of infected cases is on the rise in Asia.Several sporadic infections have been reported in China.In this study,we obtained high‐quality whole viral genomic sequences using a mpox virus‐specific amplicon‐based sequencing strategy.Our analysis of the phylogenomic characteristics indicated that all eight mpox virus sequences from Guangzhou belonged to the clade IIb lineage B.1.3 cluster.However,we could not locate the exact origins where the virus was imported,based on all the available mpox virus sequences from the Global Initiative on Sharing Avian Influenza Data(GISAID)database(http://gffzz25fa773688d24fb7sv5xkw66fwcbk6fcq.ffgz.tsg.suse.edu.cn/),except for their closest sequence similarity to that was reported from Japan.Novel amino acid mutations were found among the eight cases,suggesting that a local transmission may have occurred in Guangzhou,China. | Mengling Jiang Xizi Deng Qinghong Fan Fei Gu Huiqin Yang Jian Wang Xiaoping Tang Fengyu Hu Yun Lan Feng Li | 2023 | Biosafety and Health2023，5，5： | 0 |
| 11 | COVID-19 induces new-onset insulin resistance and lipid metabolic dysregulation via regulation of secreted metabolic factors显示文摘Abnormal glucose and lipid metabolism in COVID-19 patients were recently reported with unclear mechanism.In this study,we retrospectively investigated a cohort of COVID-19 patients without pre-existing metabolic-related diseases,and found new-onset in suli n resista nee,hyperglycemia,and decreased HDL-C in these patie nts.Mecha nistically,SARS-CoV-2 infecti on in creased the expression of RE1-silencing transcription factor(REST),which modulated the expression of secreted metabolic factors including myeloperoxidase,apelin,and myostatin at the transcriptional level,resulting in the perturbation of glucose and lipid metabolism.Furthermore,several lipids,including(±)5-HETE,(±)12-HETE,propionic acid,and isobutyric acid were identified as the potential biomarkers of COVID-19-induced metabolic dysregulation,especially in insulin resistance.Taken together,our study revealed insulin resistance as the direct cause of hyperglycemia upon COVID-19,and further illustrated the underlying mechanisms,providing potential therapeutic targets for COVID-19-induced metabolic complications. | Xi He Chenshu Liu Jiangyun Peng Zilun Li Fang Li Jian Wang Ao Hu Meixiu Peng Kan Huang Dongxiao Fan Na Li Fuchun Zhang Weiping Cai Xinghua Tan Zhongwei Hu Xilong Deng Yueping Li Xiaoneng Mo Linghua Li Yaling Shi Li Yang Yuanyuan Zhu Yanrong Wu Huichao Liang Baolin Liao Wenxin Hong Ruiying He Jiaojiao Li Pengle Guo Youguang Zhuo Lingzhai Zhao Fengyu Hu Wenxue Li Wei Zhu Zefeng Zhang Zeling Guo Wei Zhang Xiqiang Hong Wei kang Cai Lei Gu Ziming Du Yang Zhang Jin Xu Tao Zuo Kai Deng Li Yan Xinwen Chen Sifan Chen Chunliang Lei | 2022 | Signal Transduction and Targeted Therapy2022，7，1： | 0 |
| 12 | Synthetic apomixis enables stable transgenerational transmission of heterotic phenotypes in hybrid rice显示文摘In hybrid plants,heterosis often produces large,vigorous plants with high yields;however,hybrid seeds are generated by costly and laborious crosses of inbred parents.Apomixis,in which a plant produces a clone of itself via asexual reproduction through seeds,may produce another revolution in plant biology.Recently,synthetic apomixis enabled clonal reproduction of F_(1) hybrids through seeds in rice(Oryza sativa),but the inheritance of the synthetic apomixis trait and superior heterotic phenotypes across generations remained unclear.Here,we propagated clonal plants to the T_(4) generation and investigated their genetic and molecular stability at each generation.By analyzing agronomic traits,as well as the genome,methylome,transcriptome,and allele-specific transcriptome,we showed that the descendant clonal plants remained stable.Unexpectedly,in addition to normal clonal seeds,the plants also produced a few aneuploids that had eliminated large genomic segments in each generation.Despite the identification of rare aneuploids,the observation that the synthetic apomixis trait is stably transmitted through multiple generations helps confirm the feasibility of using apomixis in the future. | Chaolei Liu Zexue He Yan Zhang Fengyue Hu Mengqi Li Qing Liu Yong Huang Jian Wang Wenli Zhang Chun Wang Kejian Wang | 2023 | Plant Communications2023，4，2： | 0 |
| 13 | Transcriptome analysis of CD4^(+)T cells from HIV-infected individuals receiving ART with LLV revealed novel transcription factors regulating HIV-1 promoter activity显示文摘Some HIV-infected individuals receiving ART develop low-level viremia(LLV),with a plasma viral load of 50-1000 copies/mL.Persistent low-level viremia is associated with subsequent virologic failure.The peripheral blood CD4^(+)T cell pool is a source of LLV.However,the intrinsic characteristics of CD4^(+)T cells in LLV which may contribute to low-level viremia are largely unknown.We analyzed the transcriptome profiling of peripheral blood CD4^(+)T cells from healthy controls(HC)and HIV-infected patients receiving ART with either virologic sup-pression(VS)or LLV.To identify pathways potentially responding to increasing viral loads from HC to VS and to LLV,KEGG pathways of differentially expressed genes(DEGs)were acquired by comparing VS with HC(VS-HC group)and LLV with VS(LLV-VS group),and overlapped pathways were analyzed.Characterization of DEGs in key overlapping pathways showed that CD4^(+)T cells in LLV expressed higher levels of Th1 signature transcription factors(TBX21),toll-like receptors(TLR-4,-6,-7 and-8),anti-HIV entry chemokines(CCL3 and CCL4),and anti-IL-1βfactors(ILRN and IL1R2)compared to VS.Our results also indicated activation of the NF-κB and TNF signaling pathways that could promote HIV-1 transcription.Finally,we evaluated the effects of 4 and 17 tran-scription factors that were upregulated in the VS-HC and LLV-VS groups,respectively,on HIV-1 promoter activity.Functional studies revealed that CXXC5 significantly increased,while SOX5 markedly suppressed HIV-1 tran-scription.In summary,we found that CD4^(+)T cells in LLV displayed a distinct mRNA profiling compared to that in VS,which promoted HIV-1 replication and r+eactivation of viral latency and may eventually contribute to virologic failure in patients with persistent LLV.CXXC5 and SOX5 may serve as targets for the development of latency-reversing agents. | Jingliang Chen Yaozu He Huolin Zhong Fengyu Hu Yonghong Li Yeyang Zhang Xia Zhang Weiyin Lin Quanmin Li Feilong Xu Shaozhen Chen Hui Zhang Weiping Cai Linghua Li | 2023 | Virologica Sinica2023，38，3： | 0 |
| 14 | Screening and Assessing 11 Mycobacterium tuberculosis Proteins as Potential Serodiagnostical Markers for Discriminating TB Patients from BCG Vaccinees显示文摘Purified protein derivative (PPD) skin tests often yield poor specificity, so that to develop new serological antigens for distinguishing between Mycobacterium tuberculosis infection and Bacille Calmette-Guerin (BCG) vaccination is a priority, especially for developing countries like China. We predicted the antigenicity for selected open reading frames (ORFs) based on the genome sequences of M. tuberculosis H37Rv and M. bovis BCG, as well as their functions and differences of expression under different stimulus. The candidate ORFs were cloned from H37Rv sequences and expressed as recombinant proteins in Escherichia coli. We studied the serodiagnostic potential of 11 purified recombinants by using enzyme-linked immunosorbent assay (ELISA) and involving a cohort composed of 58 TB patients (34 males and 24 females), 8 healthy volunteers and 50 PPD-negative individuals before and after BCG vaccination. For all the 11 antigens, the median OD values for the sera from TB patients were statistically significantly higher than those for PPD-negative individuals before or after BCG vaccination (P<0.01). They had at least 92% specificity in healthy controls and six seroantigens (Rv0251c, Rv1973, Rv2376c, Rv2537c, Rv2785c and Rv3873A) were never reported with seroantigenicities previously. Thus the approach combining comparative genomics, bioinformatics and ELISA techniques can be employed to identify new seroantigens distinguishing M. tuberculosis infection from BCG vaccination. | Guoqiang Zhang Lingxia Zhang Mingcheng Zhang Linlin Pan Fengyu Wang Jun Huang Guoli Li Jun Yu Songnian Hu | 2009 | Genomics, Proteomics & Bioinformatics2009，7，3： | 0 |
| 15 | Experimental Investigation on Macro Spray Characteristics of Octanol-Biodiesel-Diesel Ternary Fuel Blend显示文摘This study investigates the spray characteristics of ternary blends composed of octanol, biodiesel, and diesel fuel.Experiments are conducted using six materials to examine the variation in spray characteristic and to verify and compare a previously established spray tip penetration model with a modified model. The results show that the addition of OB100(30%of octanol, 70% of biodiesel) improves the spray characteristics of the fuel. Specifically, the addition of 10% or 20% of OB100 leads to a slight increase in the spray tip penetration, average spray cone angle, maximum spray width, and the spray area of the fuel blend;however, further addition of OB100 causes a corresponding decrease in these parameters. Based on previous research, this study uses kinematic viscosity instead of dynamic viscosity and density to modify the prediction model of spray tip penetration. The modified model exhibits a better fit quality and agreement with the experimental data,making it more suitable for predicting the spray tip penetration of fuel blends compared to the Hiroyasu-Arai model. | Tian Junjian Qiu Zhicong Zhao Lifei Li Fengyu Hu Peng Lin Qizhao | 2023 | China Petroleum Processing & Petrochemical Technology2023，25，4： | 0 |
| 16 | Controlled growth of ultrathin ferromagneticβ-MnSe semiconductor显示文摘Two-dimensional(2D)magnetic crystals with intrinsic ferromagnetism are highly desirable for novel spin-electronic devices.However,the controllable synthesis of 2D magnets,especially the direct growth of 2D magnets on substrate surfaces,is still a challenge.Here,we demonstrate the synthesis of ultrathin zinc-blende phase manganese selenide(β-MnSe)nanosheets using the chemical vapor deposition(CVD)technique.The 2Dβ-MnSe crystals exhibit distinct ferromagnetic properties with a Curie temperature of 42.3 K.Density functional theory(DFT)calculations suggest that the ferromagnetic order inβ-MnSe originates from the exchange coupling between the unsaturated Se and Mn atoms.This study presents significant progress in the CVD growth of ultrathin 2D magnetic materials by thinning bulk magnets,and it will pave the way for the building of energy-efficient spintronic devices in the future. | Jingyun Zou Yumeng Yang Dianyi Hu Lixing Kang Chao Zhu Dan Tian Xiaodong Lv Govindan Kutty Yuxi Guo Manzhang Xu Fengyu Li Guo Hong Zheng Liu | 2022 | SmartMat2022，3，3： | 0 |
| 17 | A one-step reverse-transcription recombinase aided PCR assay for the rapid and sensitive detection of human enteroviruses显示文摘Human enteroviruses(HEVs)include many different types that cause a wide range of diseases,and an effective method of genus-level identification has therefore significant clinical implications.However,quantitative real-time reverse transcription polymerase chain reaction(qRT-PCR),the gold-standard method,still has shortfalls in diagnostic sensitivity and timeliness.Here we established a one-step real-time reverse-transcription recombinase-aided PCR assay(RT-RAP)to detect HEV fragment within an hour.The RT-RAP assay showed a detection limit of 5 copies/μL using recombinant plasmids and was extensively verified using 15 HEV strains.Among 15 types of HEV(species A-C),the sensitivity of RT-RAP was approximately 2-8 folds lower than that of the qRT-PCR in 9 types,and no-cross reaction with other viruses was observed.RT-RAP was further applied to analyze CSF and fecal specimens;the clinical performance demonstrated that the RT-RAP and the commercial qRT-PCR kit provided consistent results.These results indicated that RT-RAP assay may be a promising approach for rapid and sensitive detection of HEV. | Xiuli Sun Huanhuan Lu Yanqing Tie Mengchuan Zhao Ruiqing Zhang Zhenlu Sun Guohao Fan Fengyu Li Fengyu Tian Yaxin Hu Mengyi Zhang Xinxin Shen Xuejun Ma Zhishan Feng | 2023 | Biosafety and Health2023，5，2： | 0 |
| 18 | Pre-treatment Drug Resistance Could Impact the 96-Week Antiretroviral Efficacy in Treatment-Naive HIV-1–Infected Patients in Guangdong,China显示文摘Background:With the high prevalence of pre-treatment drug resistance(PDR)and the potential impact to the virological inhibition,the detection of PDR was particularly necessary.This study aimed to determine the prevalence of PDR in Guangdong,China,and its impact on antiretroviral therapy(ART)in treatment-naive HIV patients.Methods:A retrospective cohort study was conducted.A total of 1936 HIV-1-infected treatment-naive patients in the clinic of the infectious department,Guangzhou Eighth People’s Hospital,between August 2018 and December 2019 were assayed for PDR mutations before initiating ART.Patients with PDR mutations(PDR arm)were screened and compared with those without drug-resistant mutations(non-PDR arm).The rate of HIV-1 virologic failure(VF)and CD4^(+)T-cell counts of the 2 arms were compared at the 96th week after ART to evaluate the impact of PDR on the efficacy of ART.Results:Pretreatment drug resistance was detected in 125 cases(6.46%)from the 1936 enrolled participants,most of which were resistant to non-nucleoside reverse transcriptase inhibitors(64.00%,80/125).One hundred and eight of 125 completed the follow-up of 96 weeks(PDR arm).In this cohort,52 patients whose ART regimen containing the resistant drug were grouped as con-PDR arm,and the remaining 56 patients whose ART regimen did not contain the resistant drug were grouped as non-con-PDR arm.A total of 125 patients without PDR were randomly selected as the control group(non-PDR arm),112 of whom had completed the 96-week followup.At the 96th week after ART initiation,7 patients(6.5%,7/108)in the PDR arm and 1 patient(0.9%,1/112)in the non-PDR arm developed VF,exhibiting a significant difference(χ^(2)=4.901,P=0.029).Meanwhile,3 patients(5.8%,3/52)in the con-PDR arm developed VF;the rate was also higher than that in the non-PDR arm,but without a significant difference(χ^(2)=3.549,P=0.095).The CD4^(+)T-cell count in the non-PDR arm increased more than the PDR arm(386.6 vs.319.1 cells/μL,t=2.448,P=0.015)or the con-PDRarm(386.6 vs.325.1 cells/μL,t=1.821,P=0.070)at 12weeks afterART.However,no significant differenceswere observed in the CD4^(+)T-cell count from the 24th week after ART onward.Conclusions:Pretreatment drug resistance was moderately prevalent in Guangdong,China,and could affect the antiretroviral efficacy during a 96-week observation period,indicating the need to closely monitor PDR before ART initiation. | Pengle Guo Yun Lan Quanmin Li Xuemei Ling Junbin Li Xiaoping Tang Fengyu Hu Weiping Cai Linghua Li | 2022 | Infectious Diseases & Immunity2022，2，4： | 0 |
