| 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 | Genetic and Molecular Characterization of H9N2 Avian Influenza Viruses Isolated from Live Poultry Markets in Hubei Province, Central China, 2013–2017显示文摘H9N2 subtype avian influenza virus(AIV)is an influenza A virus that is widely spread throughout Asia,where it jeopardizes the poultry industry and provides genetic material for emerging human pathogens.To better understand the epidemicity and genetics of H9 subtype AIVs,we conducted active surveillance in live poultry markets(LPMs)in Hubei Province from 2013 to 2017.A total of 4798 samples were collected from apparent healthy poultry and environment.Realtime RT-PCR revealed that the positivity rate of influenza A was 26.6%(1275/4798),of which the H9 subtype accounted for 50.3%(641/1275)of the positive samples.Of the 132 H9N2 viral strains isolated,48 representative strains were subjected to evolutionary analysis and genotyping.Phylogenetic analysis revealed that all H9N2 viral genes had 91.1%–100%nucleotide homology,clustered with genotype 57,and had high homology with human H9N2 viruses isolated from2013 to 2017 in China.Using a nucleotide divergence cutoff of 95%,we identified ten distinct H9N2 genotypes that continued to change over time.Molecular analysis demonstrated that six H9N2 isolates had additional potential glycosylation sites at position 218 in the hemagglutinin protein,and all isolates had I155 T and Q226 L mutations.Moreover,44 strains had A558 V mutations in the PB2 protein and four had E627 V mutations,along with H9N2 human infection strains A/Beijing/1/2016 and A/Beijing/1/2017.These results emphasize that the H9N2 influenza virus in Hubei continues to mutate and undergo mammalian adaptation changes,indicating the necessity of strengthening the surveillance of the AIV H9N2 subtype in LPMs. | Zhibin Hu Fuhu Peng Zhenghui Xiong Wanpo Zhang Tingting Li Yuejun Shi Jun Xie Xin Jin Jingjing Huang Hongde Xiao Dingren Bi Nianhua Song Zili Li | 2021 | Virologica Sinica2021，36，2： | 4 |
| 3 | Mechanical properties of material in a mine dump at the Shengli#1 Surface Coal Mine,China显示文摘In-situ experiments were conducted to investigate the mechanical properties of the soil-rock mixture in the internal dump of the Shengli #1 Surface Coal Mine, China. Based on the experimental results, this study used comparative analysis and found that the shear strength of the soil-rock mixture in the dump was greater than the residual shear strength of the original rock. The results showed that the material presented in the dump as large blocks was the main factor affecting the strength of the soil-rock mixture.Numerical simulation was carried out for the analyses of three factors: different combinations of shear failure, rolling failure along with different large-block radius ratios, and mixture densities. The results illustrated that the cohesion and angle of internal friction of the soil-rock mixture are 12 kPa and 32.26°. However, in some cases the bench angle in the dump was controlled by a coupling relationship of rocks in the material. Finally, the stability of a soil slope showed a linear relationship with the large-block radius ratio and the bulk density. | Gao Shiyou Zhou Wei Shi Xuyang Cai Qingxiang Crusoe Garmondyu E.Jr. Jisen Shu Huang Yuejun | 2017 | International Journal of Mining Science and Technology2017，27，3： | 3 |

| 5 | Micropatterns and peptide gradient on the inner surface of a guidance conduit synergistically promotes nerve regeneration in vivo显示文摘Both of the surface topographical features and distribution of biochemical cues can influence the cell-substrate interactions and thereby tissue regeneration in vivo.However,they have not been combined simultaneously onto a biodegradable scaffold to demonstrate the synergistic role so far.In this study,a proof-of-concept study is performed to prepare micropatterns and peptide gradient on the inner wall of a poly(D,L-lactide-co-caprolactone)(PLCL)guidance conduit and its advantages in regeneration of peripheral nerve in vivo.After linear ridges/grooves of 20/40μm in width are created on the PLCL film,its surface is aminolyzed in a kinetically controlled manner to obtain the continuous gradient of amino groups,which are then transferred to CQAASIKVAV peptide density gradient via covalent coupling of glutaraldehyde.The Schwann cells are better aligned along with the stripes,and show a faster migration rate toward the region of higher peptide density.Implantation of the nerve guidance conduit made of the PLCL film having both the micropatterns and peptide gradient can significantly accelerate the regeneration of sciatic nerve in terms of rate,function recovery and microstructures,and reduction of fibrosis in muscle tissues.Moreover,this nerve conduit can also benefit the M2 polarization of macrophages and promote vascularization in vivo. | Deteng Zhang Ziming Li Haifei Shi Yuejun Yao Wang Du Pan Lu Kejiong Liang Liangjie Hong Changyou Gao | 2022 | Bioactive Materials2022，7，3： | 1 |
| 6 | Bioresponsive immune-booster-based prodrug nanogel for cancer immunotherapy显示文摘The combination of chemotherapy and immunotherapy motivates a potent immune system by triggering immunogenic cell death(ICD), showing great potential in inhibiting tumor growth and improving the immunosuppressive tumor microenvironment(ITM). However, the therapeutic effectiveness has been restricted by inferior drug bioavailability. Herein, we reported a universal bioresponsive doxorubicin(DOX)-based nanogel to achieve tumor-specific co-delivery of drugs. DOX-based mannose nanogels(DM NGs) was designed and choosed as an example to elucidate the mechanism of combined chemo-immunotherapy. As expected, the DM NGs exhibited prominent micellar stability, selective drug release and prolonged survival time, benefited from the enhanced tumor permeability and prolonged blood circulation. We discovered that the DOX delivered by DM NGs could induce powerful antitumor immune response facilitated by promoting ICD. Meanwhile, the released mannose from DM NGs was proved as a powerful and synergetic treatment for breast cancer in vitro and in vivo, via damaging the glucose metabolism in glycolysis and the tricarboxylic acid cycle. Overall, the regulation of tumor microenvironment with DOX-based nanogel is expected to be an effectual candidate strategy to overcome the current limitations of ICD-based immunotherapy, offering a paradigm for the exploitation of immunomodulatory nanomedicines. | Xianbin Ma Shaochen Yang Tian Zhang Shuo Wang Qichao Yang Yao Xiao Xiaoxiao Shi Peng Xue Yuejun Kang Gang Liu Zhi-Jun Sun Zhigang Xu | 2022 | Acta Pharmaceutica Sinica B2022，12，1： | 1 |

| 9 | Statistical Analysis of the Dynamic Parameters of Silty Clay in the Beijing Area显示文摘Soil dynamic parameters,including dynamic shear modulus ratio and damping ratio,have important effects on the results of layered soil earthquake response. In this paper,the mean parameter values of silty clay in different depths are obtained after statistical analysis of the experimental soil dynamic data from 20 recent site seismic safety evaluation reports in the Beijing area. Furthermore,based on two typical engineering sites,the influence of four different soil dynamic parameters,the statistic mean values,experimental values, values recommended by Yuan Xiaoming,and the values recommended in the code for seismic safety evaluation of engineering sites( DB001-94) are analyzed. The result shows that mean statistical values are applicable to seismic safety evaluation work in the Beijing area,especially for some inter-layered silty clays whose undisturbed soil samples are hard to obtain. | Shi Chunhua Lu Yuejun Peng Yanju Tang Rongyu | 2010 | Earthquake Research in China2010，24，1： | 0 |
