| 1 | Cold-chain transportation in the frozen food industry may have caused a recurrence of COVID-19 cases in destination:Successful isolation of SARS-CoV-2 virus from the imported frozen cod package surface显示文摘Coronavirus disease 2019(COVID-19)pandemic has spread in 220 countries/regions towreak havoc to human beings around theworld.At present,the second wave of COVID-19 has begun in many European countries.The complete control of COVID-19 is very urgent.Although China quickly brought the virus under control,there have been eight sporadic outbreaks in China since then.Both in Xinfadi of Beijing and Dalian outbreak of COVID-19,environmental swab samples related to imported cold chain food were tested nucleic acid positive for SARS-CoV-2.In this outbreak in Qingdao,we directly isolated SARS-CoV-2 from the cod outer package's surface swab samples.This is the first time worldwide,SARS-CoV-2 were isolated from the imported frozen cod outer package's surface,which showed that imported frozen food industry could import SARS-CoV-2 virus. | Peipei Liu Mengjie Yang Xiang Zhao Yuanyuan Guo Liang Wang Jing Zhang Wenwen Lei Weifang Han Fachun Jiang William J.Liu George F.Gao Guizhen Wu | 2020 | Biosafety and Health2020，2，4： | 41 |
| 2 | Interferon-α response in chronic hepatitis B-transfected HepG2.2.15 cells is partially restored by lamivudine treatment显示文摘AIM: To characterize the IFN-response and its modul- ation by the antiviral compound lamivudine in HBV- transfected HepG2.2.15 cells. METHODS: HepG2.2.15 and HepG2 cells were stimulated with various concentrations of IFN-a2a in the presence or absence of lamivudine. Then, total RNA was extracted and analysed by customised cDNA arrays and northern blot for interferon-inducible genes (ISGs). In addition, cellular proteins were extracted for EMSA and western blot. HBV replication was assessed by southern blot or ELISAs for HBsAg and HBeAg. RESULTS: Two genes (MxA, Cig5) with completely abolished and 4 genes (IFITM1, -2, -3, and 6-16) with partially reduced IFN-responses were identified in HepG2.2.15 cells. In 2 genes (IFITM1, 6-16), the response to IFN-a could be restored by treatment with lamivudine. This effect could not be explained by a direct modulation of the Jak/Stat signalling pathway since EMSA and western blot experiments revealed no suppression of Stat1 activation and ISGF3 formation after stimulation with IFN-a in HepG2.2.15 compared to HepG2 cells. CONCLUSION: These results are consistent with the assumption that chronic hepatitis B may specifically modulate the cellular response to IFN by a selective blockage of some ISGs. Antiviral treatment with lamivudine may partially restore ISG expression by reducing HBV gene expression and replication. | Shi-He Guan Mengji Lu Petra Grünewald Michael Roggendorf Guido Gerken Joerg F Schlaak | 2007 | World Journal of Gastroenterology2007，13，2： | 22 |
| 3 | Contribution of Toll-like receptors to the control of hepatitis B virus infection by initiating antiviral innate responses and promoting specific adaptive immune responses显示文摘适应免疫在肝炎 B 的控制起一个关键作用,这很好被接受病毒(HBV ) 感染。相反,天生的免疫的贡献仅仅在最近的年里收到了注意。像使用费的受体(TLR ) 察觉到联系病原体的分子模式并且激活抗病毒的机制,包括细胞内部的抗病毒的小径和抗病毒的受动器干扰素(IFN ) 和支持 inflammatory cytokines 的生产。从在 vitro 并且在 vivo 模型的试验性的结果证明了 TLR 调停细胞的发信号的小径和抗病毒的 cytokines 的生产的激活,导致 HBV 复制的抑制。然而, HBV 感染在主人房间和下游地表明小径的激活的封锁上与 TLR 表示的 downregulation 被联系。在主要 HBV 感染, TLR 可以减慢 HBV 感染,但是仅仅间接地作出贡献到病毒的清理。重要地, TLR 可以在 vivo 调制 HBV 特定的 T 房间和 B 房间回答,它为 HBV 感染的结束是必要的。因此, TLR 收缩筋正在答应候选人为长期的 HBV 感染的处理充当 immunomodulators。抗病毒的处理可以在长期的 HBV 感染恢复 TLR 表示和功能并且可以基于 TLR 激活增加治疗学的途径的功效。有抗病毒的治疗和 TLR 激活的联合治疗学的策略能便于 HBV 特定的有免疫力的回答的恢复并且从而,在长期地感染的 HBV 病人完成病毒的清理。 | Zhiyong Ma Ejuan Zhang Dongliang Yang Mengji Lu | 2015 | Cellular & Molecular Immunology2015，12，3： | 22 |

| 5 | Construction and Identification of a Human Liver Specific MicroRNA Eukaryotic Expression Vector显示文摘MiR-122 is one of the non-coding RNAs which showed its effects on the lipo-metablism,virus infection and HCC forming through regulation of liver gene expression.Its eukaryotic expression vector was constructed by using pSuper which was widely applied in the siRNA expression.The precursor of human miR-122 gene was amplified by polymerase chain reaction(PCR)from the human genomic DNA.The positive clones were screened by PCR and restriction enzyme digestion.The new expression vector of miR-122 was named pHsa-m122.PHsa-m122 and its controls were transfected to HepG2 cells.The miR-122 expression activity was evaluated by GFP122i sensor reporter plasmid through fluorescence detection and Western blot.It was shown that the fluorescence intensity of GFP122si and pHsa-m122 co-transfection group was weaker than that of the controls,so the functional activity of expressed miR-122 was detected.When HepG2 cells were co-transfected with HBV1.3 and pHsa-m122 plasmids, the results showed miR-122 may down-regulate the gene expression of HBV.The human liver specific microRNA eukaryotic expression vector of miR-122 was constructed successfully,which may facilitate further study of its function in the development of liver virus infection diseases and HCC. | Shanshan Chen Ming Ni Bing Yu Tingting Lv Mengji Lu Feili Gong | 2007 | Cellular & Molecular Immunology2007，4，6： | 18 |
| 6 | Exploring the molecular basis of heterosis for plant breeding显示文摘Since approximate a century ago, many hybrid crops have been continually developed by crossing two inbred varieties. Owing to heterosis(hybrid vigor) in plants, these hybrids often have superior agricultural performances in yield or disease resistance succeeding their inbred parental lines. Several classical hypotheses have been proposed to explain the genetic causes of heterosis. During recent years, many new genetics and genomics strategies have been developed and used for the identifications of heterotic genes in plants. Heterotic effects of the heterotic loci and molecular functions of the heterotic genes are being investigated in many plants such as rice, maize, sorghum, Arabidopsis and tomato.More and more data and knowledge coming from the molecular studies of heterotic loci and genes will serve as a valuable resource for hybrid breeding by molecular design in future. This review aims to address recent advances in our understanding of the genetic and molecular mechanisms of heterosis in plants. The remaining scientific questions on the molecular basis of heterosis and the potential applications in breeding are also proposed and discussed. | Jie Liu Mengjie Li Qi Zhang Xin Wei Xuehui Huang | 2020 | Journal of Integrative Plant Biology2020，62，3： | 13 |
| 7 | Recent advances in energy storage mechanism of aqueous zinc-ion batteries显示文摘Aqueous rechargeable zinc-ion batteries(ZIBs)have recently attracted increasing research interest due to their unparalleled safety,fantastic cost competitiveness and promising capacity advantages compared with the commercial lithium ion batteries.However,the disputed energy storage mechanism has been a confusing issue restraining the development of ZIBs.Although a lot of efforts have been dedicated to the exploration in battery chemistry,a comprehensive review that focuses on summarizing the energy storage mechanisms of ZIBs is needed.Herein,the energy storage mechanisms of aqueous rechargeable ZIBs are systematically reviewed in detail and summarized as four types,which are traditional Zn^(2+)insertion chemistry,dual ions co-insertion,chemical conversion reaction and coordination reaction of Zn^(2+)with organic cathodes.Furthermore,the promising exploration directions and rational prospects are also proposed in this review. | Duo Chen Mengjie Lu Dong Cai Hang Yang Wei Han | 2021 | Journal of Energy Chemistry2021，30，3： | 12 |
| 8 | Advances in biomaterials and regenerative medicine for primary ovarian insufficiency therapy显示文摘Primary ovarian insufficiency(POI)is an ovarian dysfunction that affects more than 1%of women and is characterized by hormone imbalances that afflict women before the age of 40.The typical perimenopausal symptoms result from abnormal levels of sex hormones,especially estrogen.The most prevalent treatment is hormone replacement therapy(HRT),which can relieve symptoms and improve quality of life.However,HRT cannot restore ovarian functions,including secretion,ovulation,and fertility.Recently,as part of a developing field of regenerative medicine,stem cell therapy has been proposed for the treatment of POI.Thus,we recapitulate the literature focusing on the use of stem cells and biomaterials for POI treatment,and sum up the underlying mechanisms of action.A thorough understanding of the work already done can aid in the development of guidelines for future translational applications and clinical trials that aim to cure POI by using regenerative medicine and biomedical engineering strategies. | Sichen Zhang Dashuai Zhu Xuan Mei Zhenhua Li Junlang Li Mengjie Xie Halle Jiang Williams Lutz Shaowei Wang Ke Cheng | 2021 | Bioactive Materials2021，6，7： | 9 |
| 9 | New therapeutic vaccination strategies for the treatment of chronic hepatitis B显示文摘Chronic hepatitis B virus(CHB) is currently treated with either interferon-based or nucleot(s)idebased antiviral therapies.However,treatment with pegylated interferon alpha results in a durable antiviral response in only about 30%patients and is associated with side effects.Most patients receiving nucleot(s)ide analogue treatment do not establish long-term,durable control of Infection and have rebounding viremia after cessation of therapy.Thus,novel therapy strategies are necessary to achieve the induction of potent and durable antiviral immune responses of the patients which can maintain long-term control of viral replication.Therapeutic vaccination of HBV carriers is a promising strategy for the control of hepatitis B.Here the authors review new therapeutic vaccination strategies to treat chronic hepatitis B which may be introduced for patient treatment in the future. | Jia Liu Anna Kosinska Mengji Lu Michael Roggendorf | 2014 | Virologica Sinica2014，29，1： | 9 |
| 10 | A Simple Deep Learning Network for Classification of 3D Mobile LiDAR Point Clouds显示文摘Automatic and accurate classification is a fundamental problem to the analysis and modeling of LiDAR(Light Detection and Ranging)data.Recently,convolutional neural network(ConvNet or CNN)has achieved remarkable performance in image recognition and computer vision.While significant efforts have also been made to develop various deep networks for satellite image scene classification,it still needs to further investigate suitable deep learning network frameworks for 3D dense mobile laser scanning(MLS)data.In this paper,we present a simple deep CNN for multiple object classification based on multi-scale context representation.For the pointwise classification,we first extracted the neighboring points within spatial context and transformed them into a three-channel image for each point.Then,the classification task can be treated as the image recognition using CNN.The proposed CNN architecture adopted common convolution,maximum pooling and rectified linear unit(ReLU)layers,which combined multiple deeper network layers.After being trained and tested on approximately seven million labeled MLS points,the deep CNN model can classify accurately into nine classes.Comparing with the widely used ResNet algorithm,this model performs better precision and recall rates,and less processing time,which indicated the significant potential of deep-learning-based methods in MLS data classification. | Yanjun WANG Shaochun LI Mengjie WANG Yunhao LIN | 2021 | Journal of Geodesy and Geoinformation Science2021，4，3： | 8 |

| 12 | Stepwise-Nanocavity-Assisted Transmissive Color Filter Array Microprints显示文摘Visible-light color flters using patterned nanostructures have attracted much interest due to their various advantages such as compactness,enhanced stability,and environmental friendliness compared with traditional pigment or dye-based optical flters.While most existing studies are based on planar nanostructures with lateral variation in size,shape,and arrangement,the vertical dimension of structures is a long-ignored degree of freedom for the structural colors.Herein,we demonstrate a synthetic platform for transmissive color flter array by coordinated manipulations between height-varying nanocavities and their lateral flling fractions.Te thickness variation of those nanocavities has been fully deployed as an alternative degree of freedom,yielding vivid colors with wide gamut and excellent saturation.Experimental results show that the color-rendering capability of the pixelated nanocavities can be still retained as pixels are miniaturized to 500 nm.Crosstalk between closely spaced pixels of a Bayer color flter arrangement was calculated,showing minimal crosstalk for 1μm2 square subpixels.Our work provides an approach to designing and fabricating ultracompact color flter arrays for various potential applications including stained-glass microprints,microspectrometers,and high-resolution image sensing systems. | Yasi Wang Mengjie Zheng Qifeng Ruan Yanming Zhou Yiqin Chen Peng Dai Zhengmei Yang Zihao Lin Yuxiang Long Ying Li Na Liu Cheng-Wei Qiu Joel K.W.Yang Huigao Duan | 2018 | Research2018，，1： | 8 |

| 14 | Ultraselective carbon molecular sieve membrane for hydrogen purification显示文摘Hydrogen is a green clean fuel and chemical feedstock. Its separation and purification from hydrogencontaining mixtures is the key step in the production of hydrogen with high purity(>99.99%). In this work, carbon molecular sieve(CMS) membranes with ultrahigh permselectivity for hydrogen purification were fabricated by high-temperature(700–900 ℃) pyrolysis of polymeric precursor of phenolphthaleinbased cardo poly(arylene ether ketone)(PEK-C). The evolution of the microstructural texture and ultramicroporous structure and gas separation performance of the CMS membrane were characterized via TG-MS, FT-IR, XRD, TEM, CO2 sorption analysis and gas permeation measurements. CMS membranes prepared at 700 ℃ exhibited amorphous turbostratic carbon structures and high H2 permeability of 5260 Barrer with H2/CH4, H2/N2 and H2/CO selectivities of 311, 142, 75, respectively. When carbonized at900 ℃, the CMS membrane with ultrahigh H2/CH4 selectivity of 1859 was derived owing to the formation of the dense and ordered carbon structure. CMS membranes with ultrahigh permselectivity exhibit an attractive application prospect in hydrogen purification. | Ruisong Xu Liu He Lin Li Mengjie Hou Yongzhao Wang Bingsen Zhang Changhai Liang Tonghua Wang | 2020 | Journal of Energy Chemistry2020，29，11： | 8 |
| 15 | Single-cell Immune Landscape of Human Recurrent Miscarriage显示文摘t Successful pregnancy in placental mammals substantially depends on the establishment of maternal immune tolerance to the semi-allogenic fetus.Disorders in this process are tightly associated with adverse pregnancy outcomes including recurrent miscarriage(RM).However,an indepth understanding of the systematic and decidual immune environment in RM remains largely lacking.In this study,we utilized single-cell RNA-sequencing(scRNA-seq)to comparably analyze the cellular and molecular signatures of decidual and peripheral leukocytes in normal and unexplained RM pregnancies at the early stage of gestation.Integrative analysis identifies 22 distinct cell clusters in total,and a dramatic difference in leukocyte subsets and molecular properties in RM cases is revealed.Specifically,the cytotoxic properties of CD8^(+)effector T cells,nature killer(NK),and mucosal-associated invariant T(MAIT)cells in peripheral blood indicates apparently enhanced pro-inflammatory status,and the population proportions and ligand–receptor interactions of the decidual leukocyte subsets demonstrate preferential immune activation in RM patients.The molecular features,spatial distribution,and the developmental trajectories of five decidual NK(dNK)subsets have been elaborately illustrated.In RM patients,a dNK subset that supports embryonic growth is diminished in proportion,while the ratio of another dNK subset with cyto toxic and immune-active signature is significantly increased.Notably,a unique pro-inflammatory CD56^(+)CD16^(+)dNK subset substantially accumulates in RM decidua.These findings reveal a comprehensive cellular and molecular atlas of decidual and peripheral leukocytes in human early pregnancy and provide an in-depth insight into the immune pathogenesis for early pregnancy loss. | Feiyang Wang Wentong Jia Mengjie Fan Xuan Shao Zhilang Li Yongjie Liu Yeling Ma Yu-Xia Li Rong Li Qiang Tu Yan-Ling Wang | 2021 | Genomics, Proteomics & Bioinformatics2021，19，2： | 8 |
| 16 | The role of micro RNAs in hepatocyte metabolism and hepatitis B virus replication显示文摘Though efficient vaccines against hepatitis B virus(HBV) and antiviral therapies are available,chronic HBV infection is still a global health problem. The process of HBV infection and HBV life cycle are extensively studied in last decades, however, the mechanisms of HBV-induced alterations of host cell metabolisms and host factors involved in modulating of viral replication are not fully understood. Thus, it is an important issue to examine these specific HBV-host interactions for development of novel strategies for antiviral therapies. Recently, microRNAs(miRNAs), a class of post-transcriptional regulatory small RNA, seem to be the relevant fine tuning factors of various cellular activities and pathways, including cell growth, metabolism, and viral replication. In this review, we summarize the up to date knowledge concerning the virus-host interactions and emphasizing on the role of miRNAs in regulation of HBV replication and host cell metabolism. | Wanyu Deng Mengji Lu | 2016 | Virologica Sinica2016，31，6： | 7 |
| 17 | A Case of Hepatitis B Reactivation due to the Hepatitis B Virus Escape Mutant in a Patient undergoing Chemotherapy显示文摘A 62-year-old man had chronic hepatitis B virus (HBV) infection and was diagnosed with liver cirrhosis.At the time of diagnosis the patient's virologic markers were positive for hepatitis B surface antigen (HBsAg),antibody to hepatitis B e antigen (anti-HBe) and antibody to hepatitis B core antigen (anti-HBc),while antibody to hepatitis B surface antigen (anti-HBs) and HBV DNA were negative.Later the patient received chemotherapy for malignancy.However,this was interrupted due to elevated liver enzymes.At the same time HBV DNA became positive.Lamivudine (LMV) therapy was administered immediately.However,the levels of serum aminotransferase and total bilirubin (TB) were still rising.Finally the patient died of fulminant hepatic failure.A sequence revealed HBV genotype C (HBsAg subtype adw) with immune escape mutations,F8L,S34L,F41S,G44V,F93C,V96G,L110I,C149Y and F161Y.The high morbidity and mortality of this complication is one of the major obstacles to completing the standard treatment for malignancy in HBV carriers.Therefore,the relative risk of antiviral prophylactic failure should be further assessed and the optimal strategy for antiviral prophylaxis in HBsAg-positive patients with oncologic and hematologic malignancies undergoing chemotherapy should be revised. | Chunchen Wu Hui Shi Yun Wang Mengji LU Yang Xu Xinwen Chen | 2012 | Virologica Sinica2012，27，6： | 7 |
| 18 | Progress Towards the 90-90-90 Targets for Controlling HIV --China, 2018显示文摘What is already known about this topic?Since the Joint United Nations Programme on HIV and AIDS(UNAIDS)announced the 90-90-90 targets to control the global HIV epidemic in 2014,many countries have undertaken innovative measures to achieve this goal.The National Center for AIDS/STD Control and Prevention(NCAIDS)of China CDC convenes experts annually to evaluate the national progress towards these indicators.The most recent progress of 90-90-90 targets in China has not been previously published.What is added by this report?At the end of 2018,the percentage of living with HIV(PLWH)who had received a confirmed HIV diagnosis in China was 68.9%(61.5%-78.3%).The antiretroviral treatment coverage of diagnosed PLWH was 83.4%,and among patients on treatment for at least 12 months,94.2%achieved viral suppression.This provides most recent progress of 90-90-90 target in China.What are the implications for public health practice?China has made significant strides in curbing the HIV epidemic,but analysis on progress for the first 90 target for HIV testing remains out of reach.Innovative testing strategies may need to be developed to ensure that more PLWH can be identified. | Yan Zhao Mengjie Han Ye Ma Dongmin Li | 2019 | China CDC weekly2019，1，1： | 7 |
