2Angiotensin II receptor blocker as a novel therapy in acute lung injury induced by avian influenza A H5N1 virus infection in mouse显示文摘Dear Editor,Since the first recognized case of human infection with avian influenza H5N1 virus in 1997,the worldwide spread and re-emergence of this highly pathogenic influenza virus have led to 694 human infection cases.Of these cases,402died from 2003 to 2015(http://gffzz36b398b81f8a4a4chkqxfcvukq96c66px.ffgz.tsg.suse.edu.cn/influenza/humananimalinterface/ENGIP20150106CumulativeNumber H5N1cases.pdf?ua=1),with a morbidity rateYAN YiWu LIU Qiang LI Ning DU JianChao LI Xiao LI Chang JIN NingYi JIANG ChengYu 2015Science China(Life Sciences)2015,58,2:12
3Construction and anti-tumor effects of recombinant fowlpox virus expressing Newcastle disease virus hemagglutinin-neuramidinase gene显示文摘Hemagglutinin-neuramidinase (HN ) ,纽卡斯尔疾病导出病毒的蛋白质,不是仅仅调停受体识别而且拥有 neuraminidase (NA ) 活动,劈开那些受体的一个部件的能力, N-acetylneuraminic 酸(NAcneu, sialic ) 。包括人,在哺乳动物的种类的这蛋白质有有趣的反肿瘤以及有免疫力的刺激性质,这被知道。在癌症基因治疗探索 HN 基因的使用,我们构造了表示 HN 蛋白质(vFV-HN ) 的一个 recombinant 家禽痘病毒并且在 vivo 并且在 vitro 把 recombinant 病毒的 theanti 肿瘤活动与野类型的家禽痘病毒(FPV ) 的作比较。这里,我们发现尽管 B16 房间对野类型的家禽痘病毒的基础细胞毒素的效果有点抵抗,有 vFV-HN 的感染引起了显著细胞毒素的效果并且,与 vFV-HN 使免疫的忍受肿瘤的老鼠的幸存显著地与独自与 FPV 使免疫的老鼠的幸存相比被增加。而且,有 vFV-HNelicited 的老鼠的免疫 B16 肿瘤特定的细胞毒素的 T 淋巴细胞(CTL ) 回答和在 vivo 的 bothCD4+ 和 CD8+ T 房间人口的同种细胞的扩大。另外,从老鼠的淋巴节点的 T 房间种牛痘, Th1 cytokine IL-2 和 IFN-v 高级的 vFV-HN 藏匿了,显示肿瘤房间的回归与 Th1 类型主导的有免疫力的回答有关。这些结果证明有 vFV-HN 的种痘可以是为癌症基因治疗的潜在的策略。LI Xiao JIN Ningyi LIAN Hai GUAN Goufang SUN Lili LI Xue mei ZHENG Hongling 2006Chinese Science Bulletin2006,51,22:9
4Immunogenicity analysis following human immunodeficiency virus recombinant DNA and recombinant vaccinia virus Tian Tan prime-boost immunization显示文摘This study assessed and compared the immunogenicity of various immunization strategies in mice using combinations of recombinant DNA(pCCMp24) and recombinant attenuated vaccinia virus Tian Tan(rddVTT-CCMp24).Intramuscular immunization was performed on days 0(prime) and 21(boost).The immunogenicity of the vaccine schedules was determined by measuring human immunodeficiency virus(HIV)-specific binding antibody levels and cytokine(interleukin-2 and interleukin-4) concentrations in peripheral blood,analyzing lymphocyte proliferation capacity against HIV epitopes and CD4 + /CD8 + cell ratio,and monitoring interferon-gamma levels at different times post-immunization.The results showed that pCCMp24,rddVTT-CCMp24 and their prime-boost immunization induced humoral and cellular immune responses.The pCCMp24/rddVTT-CCMp24 immunization strategy increased CD8 + T cells and induced more IFN-γ-secreting cells compared with single-shot rDNA.The prime-boost immunization strategy also induced the generation of cellular immunological memory to HIV epitope peptides.These results demonstrated that prime-boost immunization with rDNA and rddVTT-CCMp24 had a tendency to induce greater cellular immune response than single-shot vaccinations,especially IFN-γ response,providing a basis for further studies.LIU CunXia DU ShouWen LI Chang WANG YuHang WANG MaoPeng LI Yi YIN RongLan LI Xiao REN DaYong QIN YanQing REN JingQiang JIN NingYi 2013Science China(Life Sciences)2013,56,6:7
5Tauroursodeoxycholic acid(TUDCA) inhibits influenza A viral infection by disrupting viral proton channel M2显示文摘Influenza is a persistent threat to human health and there is a continuing requirement for updating antiinfluenza strategies. Initiated by observations of different endoplasmic reticulum(ER) responses of host to seasonal H1N1 and highly pathogenic avian influenza(HPAI) A H5N1 infections, we identified an alternative antiviral role of tauroursodeoxycholic acid(TUDCA), a clinically available ER stress inhibitor, both in vitro and in vivo. Rather than modulating ER stress in host cells, TUDCA abolished the proton conductivity of viral M2 by disrupting its oligomeric states, which induces inefficient viral infection. We also showed that M2 penetrated cells, whose intracellular uptake depended on its proton channel activity,an effect observed in both TUDCA and M2 inhibitor amantadine. The identification and application of TUDCA as an inhibitor of M2 proton channel will expand our understanding of IAV biology and complement current anti-IAV arsenals.Ning Li Yanxu Zhang Shuangxiu Wu Ruodan Xu Zhiqing Li Jindong Zhu Hongliang Wang Xiao Li Mingyao Tian Huijun Lu Ningyi Jin Chengyu Jiang 2019Science Bulletin2019,64,3:6
6Molecular and serological surveillance of Getah virus in the Xinjiang Uygur Autonomous Region,China,2017–2020显示文摘The Getah virus(GETV),a mosquito-borne RNA virus,is widely distributed in Oceania and Asia.GETV is not the only pathogenic to horses,pigs,cattle,foxes and boars,but it can also cause fever in humans.Since its first reported case in Chinese mainland in 2017,the number of GETV-affected provinces has increased to seventeen till now.Therefore,we performed an epidemiologic investigation of GETV in the Xinjiang region,located in northwestern China,during the period of 2017-2020.ELISA was used to analyze 3299 serum samples collected from thoroughbred horse,local horse,sheep,goat,cattle,and pigs,with thoroughbred horse(74.8%),local horse(67.3%),goat(11.7%),sheep(10.0%),cattle(25.1%)and pigs(51.1%)being positive for anti-GETV antibodies.Interestingly,the neutralizing antibody titer in horses was much higher than in other species.Four samples from horses and pigs were positive for GETV according to RT-PCR.Furthermore,from the serum of a local horse,we isolated GETV which was designated as strain XJ-2019-07,and determined its complete genome sequence.From the phylogenetic relationships,it belongs to the Group III lineage.This is the first evidence of GETV associated to domestic animals in Xinjiang.Overall,GETV is prevalent in Xinjiang and probably has been for several years.Since no vaccine against GETV is available in China,detection and monitoring strategies should be improved in horses and pigs,especially imported and farmed,in order to prevent economic losses.Ning Shi Xiangshu Qiu Xinyu Cao Zhanhai Mai Xiangyu Zhu Nan Li He Zhang Jinyong Zhang Zhuoxin Li Nuerlan Shaya Huijun Lu Ningyi Jin 2022Virologica Sinica2022,37,2:5
7Chimeric Newcastle Disease Virus-like Particles Containing DC-Binding Peptide-Fused Haemagglutinin Protect Chickens from Virulent Newcastle Disease Virus and H9N2 Avian Influenza Virus Challenge显示文摘Newcastle disease virus(NDV)and H9N2 subtype Avian influenza virus(AIV)are two notorious avian respiratory pathogens that cause great losses in the poultry industry.Current inactivated commercial vaccines against NDV and AIV have the disadvantages of inadequate mucosal responses,while an attenuated live vaccine bears the risk of mutation.Dendritic cell(DC)targeting strategies are attractive for their potent mucosal and adaptive immune-stimulating ability against respiratory pathogens.In this study,DC-binding peptide(DCpep)-decorated chimeric virus-like particles(cVLPs),containing NDV haemagglutinin–neuraminidase(HN)and AIV haemagglutinin(HA),were developed as a DC-targeting mucosal vaccine candidate.DCpep-decorated cVLPs activated DCs in vitro,and induced potent immune stimulation in chickens,with enhanced secretory immunoglobulin A(sIgA)secretion and splenic T cell differentiation.40μg cVLPs can provide full protection against the challenge with homologous,heterologous NDV strains,and AIV H9N2.In addition,DCpep-decorated cVLPs could induce a better immune response when administered intranasally than intramuscularly,as indicated by robust s IgA secretion and a reduced virus shedding period.Taken together,this chimericVLPs are a promising vaccine candidate to control NDV and AIV H9N2 and a useful platform bearing multivalent antigens.Xiaohong Xu Jing Qian Lingsong Qin Jindou Li Cong Xue Jiaxin Ding Weiqi Wang Wei Ding Renfu Yin Ningyi Jin Zhuang Ding 2020Virologica Sinica2020,35,4:4
8Immune responses of a designed HIV-1 DNA vaccine on rhesus monkeys显示文摘An effective HIV-1 vaccine will be the ultimate solution for the prevention of HIV/AIDS, though HAART plays important roles in treating the disease. In this study, a large-scale recombinant DNA plasmid containing a designed HIV-1 multi-epitope- p24 chimeric gene was prepared and purified. Rhesus monkeys were then inoculated muscularly with the plasmid for four times in week 0, 4, 8 and 18. Whole blood was collected two weeks after the third and fourth inoculation, followed by serum and pe- ripheral blood mononuclear cell (PBMC) separation. The CTL activity and proliferation of PBMCs stimu- lated by macaque MHC-I-restricted HIV-1 CTL epi- tope peptide were analyzed by MTT and LDH release assay, respectively. Th1 cytokines in supernatant of cultured PBMC stimulated by HIV-1 CTL epitope peptide and anti-HIV-1 antibody in serum were as- sayed by ELISA. The results showed that increased CTL target-killing activity, higher secretion of Th1 cytokines (IFN-γ and IL-2) and promoted proliferative reaction of monkey PBMCs stimulated by HIV-1 CTL epitope peptide were detected in the immunization group inoculated by the recombinant DNA vaccine for three times, which were further enhanced by the fourth inoculation. At the same time, HIV-1 specific antibody in serum of immunized monkeys was higher than that in controls. We concluded that the designedHIV-1 DNA vaccine may induce HIV-1 specific cellular and humoral immunity on monkeys.ZHANG Lishu JIN Ningyi SONG Yingjin SUN Yansong WANG Hong ZHAN Dawei MA Hewen SHANG Yupu JIN Hongtao HONG Baoqing LI Chang 2006Chinese Science Bulletin2006,51,13:3

11Rapidly developable therapeutic-grade equine immunoglobulin against the SARS-CoV-2 infection in rhesus macaques显示文摘Dear Editor,The unprecedented COVID-19 pandemic caused by SARS-CoV-2 remains ongoing,but there is a lack of fully effective treatments.Convalescent plasma-derived hyperimmune globulins have been a safe and effective treatment but restricted by the difficulties in obtaining sufficient plasma with high antibody titers from a large number of recovered patients.Heterologous antibodies,particularly equine antibodies,have been widely used for decades as the therapeutics against some viral infections or as antivenoms.1 Equine antibodies could be rapidly developed and manufactured into therapeutic antibodies in large quantities under WHO standardized guidelines.Here we explored the development of equine antibody-derived F(ab′)2 as an option to treat COVID-19 by targeting the receptor-binding domain(RBD)of the viral spike protein that is essential for the viral entry into the host cells.2 We observed excellent neutralization titers of the F(ab′)2 in vitro and high potency against SARS-CoV-2 infection in the nonhuman primate rhesus macaques.Xiaolei Liu Yi Liu Xuemin Jin Zhanlong He Zhen Huang Shumin Sun Yuwei Gao Jingyu Li Qin Ning Zhongping Xie Ningyi Jin Mingyuan Liu 2022Signal Transduction and Targeted Therapy2022,7,8:2
12Orally administered BZL-s RNA-20 oligonucleotide targeting TLR4 effectively ameliorates acute lung injury in mice显示文摘The global COVID-19 pandemic emerged at the end of December 2019.Acute respiratory distress syndrome(ARDS)and acute lung injury(ALI)are common lethal outcomes of bacterial lipopolysaccharide(LPS),avian influenza virus,and SARS-Co V-2.Toll-like receptor 4(TLR4)is a key target in the pathological pathway of ARDS and ALI.Previous studies have reported that herbal small RNAs(s RNAs)are a functional medical component.BZL-s RNA-20(Accession number:B59471456;Family ID:F2201.Q001979.B11)is a potent inhibitor of Toll-like receptor 4(TLR4)and pro-inflammatory cytokines.Furthermore,BZLs RNA-20 reduces intracellular levels of cytokines induced by lipoteichoic acid(LTA)and polyinosinic-polycytidylic acid(poly(I:C)).We found that BZL-s RNA-20 rescued the viability of cells infected with avian influenza H5N1,SARS-Co V-2,and several of its variants of concern(VOCs).Acute lung injury induced by LPS and SARS-Co V-2 in mice was significantly ameliorated by the oral medical decoctosome mimic(bencaosome;sphinganine(d22:0)+BZL-s RNA-20).Our findings suggest that BZLs RNA-20 could be a pan-anti-ARDS/ALI drug.Dandan Zhao Yuhao Qin Jiaqi Liu Kegong Tang Shuaiyao Lu Zirui Liu Yexuan Lin Cong Zhang Fengming Huang Jiahui Chang Chang Li Mingyao Tian Yiming Ma Xiaoyun Li Congzhao Zhou Xiao Li Xiaozhong Peng Ningyi Jin Chengyu Jiang 2023Science China(Life Sciences)2023,66,7:1

14Transient heat transfer characteristics of air-array-jet impingement with different nozzle arrangements on high-tempera-ture flat plate in small jet-to-plate distance显示文摘Numerical studies on transient heat transfer characteristics of air-array-jet impingement with a small jet-to-plate distance and a large temperature difference between nozzles and plate were presented.The dimensionless jet-to-plate distance(H/D)was 0.2,and non-dimensional nozzle-to-nozzle spacing(S/D)was 3,4,5 and 6,respectively.It is found that the quenching time is shortened at a constant total mass flow at air jet inlet m·(m·=218.21 kg/h),and the heat transfer uniformity is deterio-rated as S/D increases.However,the adding reversed-flow nozzles can shorten the quenching time of the glass plate considerably with a modest change in the heat transfer uniformity.The results at variable m·are the same as those at a fixed m·.Furthermore,the parity and arrangement of nozzles are also discussed,It is found that an odd number of nozzles is more beneficial for transient heat transfer.Based on these results,an appropriate proposal for ultra-thin glass tempering process is presented.LI Meixiang ZHU Keqian XIE Yu CAI Tingting YUAN Ningyi DING Jianning 2020排灌机械工程学报2020,38,3:1

16Construction and characterization of a recombinant fowlpox virus containing HIV-1 multi-epitope-p24 chimeric gene in mice显示文摘The epidemic of HIV/AIDS is sweeping across the world. It is of great importance to figure out new ways to curb this disease. Epitope-based vaccine is one of these solutions. In this study, a chimeric gene was obtained by combination of a designed HIV-1 multi-epitope gene (MEG) and HIV-1 p24 gene. A re- combinant plasmid pUTA2-MEGp24 was then constructed by inserting MEGp24 gene into the down- stream of the promoter (ATI-P7.5×20) of fowlpox virus (FPV) transfer vector pUTA2. The recombinant plasmid and wild-type FPV 282E4 strain were then co-transfected into CEF cells and homologous re- combination occurred. A recombinant virus expressing HIV-1 protein MEGp24 was screened by ge- nome PCR and Western blot assay. Large scale preparation and purification of the recombinant fowl- pox virus (rFPV) were then carried out. BALB/c mice were immunized intramuscularly with the rFPV for three times on day 0, 14 and 42. Mice were executed and sampled one week after the third inoculation. Anti-HIV-1 antibody in serum and Th1 cytokines in the supernatant of cultured spleen cells were as- sayed by ELISA. The count of T lymphocyte subsets and the CTL activity of spleen lymphocytes were analyzed by flow cytometry and lactate dehydrogenase (LDH) release assay, respectively. The results showed that HIV-1 specific antibody in serum and increased T lymphocyte subsets (CD4+ T, CD8+ T) were detected in the immunization group. CTL target-killing activity and higher secretion of Th1 cyto- kines (IFN-γ and IL-2) of spleen lymphocytes stimulated by H-2d-restricted CTL peptide were observed in immunized mice. We concluded that the rFPV may induce HIV-1 specific immunity especially cellular immunity in mice.ZHANG LiShu JIN NingYi SONG YingJin WANG Hong MA HeWen LI ZiJian JIANG WenZheng 2007Science China(Life Sciences)2007,50,2:1

20Experimental investigation of crossflow characteristics in multi-jets system at small nozzle-to-plate spacing显示文摘To further extend knowledge about the detailed knowledge on the crossflow characteristics in a multi-jets system under a confined space,particle image velocimetry (PIV) was employed to investigate the flow structures together with the distributions of the mean velocity components for Reynolds numbers (Re) ranging from 6 213 to 13 418,nozzle-to-plate spacing (H/D) varying from 0. 20 to1. 25,respectively. Results show that the crossflow configuration is significantly different from those of large nozzle-to-plate spacing. In addition,a turning point H/D=0.50 is revealed in the profile of the normalized maximum radial velocity which is associated with the heat transfer distribution on the impingement plate.ZHU Keqian SUN Tao YU Pingping LI Meixiang YUAN Ningyi DING Jianning 2019排灌机械工程学报2019,37,2:1
