1Clinical and biochemical indexes from 2019-nCoV infected patients linked to viral loads and lung injury显示文摘The outbreak of the 2019-nCoV infection began in December 2019 in Wuhan,Hubei province,and rapidly spread to many provinces in China as well as other countries.Here we report the epidemiological,clinical,laboratory,and radiological characteristics,as well as potential biomarkers for predicting disease severity in 2019-nCoV-infected patients in Shenzhen,China.All 12 cases of the 2019-nCoV-infected patients developed pneumonia and half of them developed acute respiratory distress syndrome (ARDS).The most common laboratory abnormalities were hypoalbuminemia,lymphopenia,decreased percentage of lymphocytes (LYM) and neutrophils (NEU),elevated C-reactive protein (CRP) and lactate dehydrogenase (LDH),and decreased CD8 count.The viral load of 2019-nCoV detected from patient respiratory tracts was positively linked to lung disease severity.ALB,LYM,LYM (%),LDH,NEU (%),and CRP were highly correlated to the acute lung injury.Age,viral load,lung injury score,and blood biochemistry indexes,albumin (ALB),CRP,LDH,LYM (%),LYM,and NEU (%),may be predictors of disease severity.Moreover,the Angiotensin Ⅱlevel in the plasma sample from 2019-nCoV infected patients was markedly elevated and linearly associated to viral load and lung injury.Our results suggest a number of potential diagnosis biomarkers and angiotensin receptor blocker (ARB) drugs for potential repurposing treatment of 2019-nCoV infection.Yingxia Liu Yang Yang Cong Zhang Fengming Huang Fuxiang Wang Jing Yuan Zhaoqin Wang Jinxiu Li Jianming Li Cheng Feng Zheng Zhang Lifei Wang Ling Peng Li Chen Yuhao Qin Dandan Zhao Shuguang Tan Lu Yin Jun Xu Congzhao Zhou Chengyu Jiang Lei Liu 2020Science China(Life Sciences)2020,63,3:157
2China's wetland change (1990-2000) determined by remote sensing显示文摘Two wetland maps for the entire China have been produced based on Landsat data acquired around 1990 and 2000. Wetlands in China have been divided into 3 broad categories with 15 sub-categories except rice fields. In 1990, the total wetland area in China was 355208 km2 whereas in 2000 it dropped to 304849 km2 with a net loss of 50360 km2. During an approximate 10-year period, inland wetland reduced from 318326 to 257922 km2, coastal wetland dropped from 14335 to 12015 km2, while artificial wetland increased from 22546 to 34911 km2. The greatest natural wetland loss occurred in Heilongjiang, Inner Mon- golia, and Jilin with a total loss of over 57000 km2 of wetland. In western China, over 13000 km2 of wetlands were newly formed in Xinjiang, Tibet, and Qinghai. About 12000 km2 of artificial wetlands were also added for fish farm and reservoir constructions. The newly formed wetlands in western China were caused primarily by climate warming over that region whereas the newly created artificial wetlands were caused by economic developments. China’s wetland loss is caused mainly by human activities.Peng Gong ZhenGuo Niu Xiao Cheng KuiYi Zhao DeMin Zhou JianHong Guo Lu Liang XiaoFeng Wang DanDan Li HuaBing Huang et al. 2010Science China Earth Sciences2010,53,7:28
3Herbal decoctosome is a novel form of medicine显示文摘Traditionally, herbal medicine is consumed by drinking decoctions produced by boiling herbs with water. The functional components of the decoction are heat stable. Small RNAs(sRNAs) were reported as a new class of functional components in decoctions. However, the mechanisms by which sRNAs survive heat treatment of the decoction and enter cells are unclear.Previous studies showed that plant-derived exosome-like nanoparticles(ELNs), which we call botanosomes, could deliver therapeutic reagents in vivo. Here, we report that heat-stable decoctosomes(ELNs) from decoctions have more therapeutic effects than the decoctions in vitro and demonstrate therapeutic efficacy in vivo. Furthermore, sRNAs, such as HJT-sRNA-m7 and PGY-sRNA-6, in the decoctosome exhibit potent anti-fibrosis and anti-inflammatory effects, respectively. Decoctosome is comprised of lipids, chemical compounds, proteins, and s RNAs. A medical decoctosome mimic is called bencaosome. A single lipid sphinganine(d22:0) identified in the decoctosome was mixed and heated with the synthesized sRNAs to form the simplest bencaosome. This simple bencaosome structure was identified by critical micelle concentration(cmc) assay that sRNAs coassembled with sphinganine(d22:0) to form the lipid layers of vesicles. The heating process facilitates co-assembly of sRNAs and sphinganine(d22:0) until a steady state is reached. The artificially produced sphinganine-HJT-sRNA-m7 and sphinganinePGY-sRNA-6 bencaosomes could ameliorate bleomycin-induced lung fibrosis and poly(I:C)-induced lung inflammation, respectively, following oral administration in mice. Our study not only demonstrates that the herbal decoctosome may represent a combinatory remedy in precision medicine but also provides an effective oral delivery route for nucleic acid therapy.Xiaoyun Li Zhu Liang Jianchao Du Zhiqing Wang Song Mei Zhiqing Li Yan Zhao DANDan Zhao Yiming Ma Jun Ye Jiantao Xu Yu Zhao Jiahui Chang Yuhao Qin Lanlan Yu Chenxuan Wang Chengyu Jiang 2019Science China(Life Sciences)2019,62,3:26
4Plant-derived phosphocholine facilitates cellular uptake of anti-pulmonary fibrotic HJT-sRNA-m7显示文摘Pulmonary fibrosis, a progressive chronic disease with a high mortality rate, has limited treatment options. Currently, lung transplantation remains the only effective treatment. Here we report that a small RNA, HJT-sRNA-m7, from a Chinese herbal medicine Hong Jing Tian(HJT, RHODIOHAE CRENULATAE RADIX ET RHIZOMA, Rhodiola crenulata) can effectively reduce the expressions of fibrotic hallmark genes and proteins both in alveolar in vitro and in mouse lung tissues in vivo. We also discovered over one hundred oil-soluble chemicals from HJT decoctions, most of which are found in lipid extracts from other Chinese herbals decoctions, including Pu Gong Ying(PGY, TARAXACI HERBA, Taraxacum mongolicum), Chuan Xin Lian(CXL, changed to 'ANDROGRAPHIS HERBA, Andrographis paniculata'), and Jin Yin Hua(JYH, lonicera japonica or Honeysuckle). We identified the active component in these decoctions as two forms of phosphocholines, PC(18:0/18:2) and PC(16:0/18:2). These PCs potentially could form liposomes with small RNAs to enter human alveolar and gastric cells. Our experimental results suggest an unprecendent lipid complex route through which botanic small RNA can enter human bodies.Our results provide an innovative treatment strategy for oral delivery of siRNAs as therapeutic medication.Jianchao Du Zhu Liang Jiantao Xu Yan Zhao Xiaoyun Li Yanli Zhang DANDan Zhao Ruxuan Chen Yang Liu Trupti Joshi Jiahui Chang Zhiqing Wang Yanxu Zhang Jindong Zhu Qiang Liu Dong Xu Chengyu Jiang 2019Science China(Life Sciences)2019,62,3:21
5Development and application of mechanized maize harvesters显示文摘Maize harvesting is one of the most important filed operations of maize production.As the accelerating development of maize industry,mechanized maize harvesting is widely accepted and used by farmers in the world.According to the harvesting methods,maize harvesters could be classified into two types,one is maize-for-grain harvesters,including pickers and grain harvesters,the other is whole plant harvesters,including forage harvesters and combined grain-stover harvesters.Structure characteristics,appropriate areas and relative technologies of those harvesters are described in this paper,i.e.,pickers are suitable for multi-crop areas,Grain harvesters are mainly for one-crop areas when grain moisture content is lower than 25%,combined grain-stover harvesters are applicable in agro-pastoral ecotone,and forage harvesters are capable in large-scaled animal husbandry farming areas where large amount of silage are required.Meanwhile,the future development trend of the different harvesters is predicted.Big horsepower engines,enhanced working efficiency,automation and intelligence are required by large scaled farms.As maize breeding development,more varieties that are suitable for grain harvesting are put into practice,so grain combine harvesters will be popular in future.Yang Li Cui Tao Qu Zhe Li Kehong Yin Xiaowei Han Dandan Yan Bingxin Zhao Dongyue Zhang Dongxing 2016International Journal of Agricultural and Biological Engineering2016,9,3:13
6Multiaxial electrospun generation of hollow graphene aerogel spheres for broadb and high-performance microwave absorption显示文摘Although graphene aerogels(GA)have been attracted great attention,the easy-operation and large-scale production of GA are still challenges.Further,most GA have a monolith-like appearance,limiting their application-specific needs.Herein,we highlight graphene aerogel spheres with controllable hollow structures(HGAS)that are delicately designed and manufactured via coaxial electrospinning coupled with freeze-drying and calcination.The HGAS exhibit a spherical configuration at the macroscale,while the construction elements of graphene on the microscale showing an interconnected radial microchannel structure.Further ball-in-ball graphene aerogel spheres(BGAS)are obtained by reference to the triaxial electrospinning technology.The as-prepared spheres possess the controllable integrated conductive networks,leading to the effective dielectric loss and impedance matching thus bringing on high-performance microwave absorption.The as-obtained HGAS shows a minimum reflection loss of-52.7 dB and a broad effective absorption bandwidth(f)of 7.0 GHz with thickness of 2.3 mm.Further,the fe reaches 9.3 GHz for BGAS with thickness of 3.4 mm.Aforementioned superior microwave absorption of HGAS and BGAS confirms combination of multiaxial electrospinning and freeze-drying on the multiscale is an effective strategy for scalable fabrication of advanced microwave.absorbing functional graphene aerogel spheres.Tian Li Dandan Zhi Yao Chen Bing Li Zuowan Zhou Fanbin Meng 2020Nano Research2020,13,2:13
7Cardioprotective mechanism of SGLT2 inhibitor against myocardial infarction is through reduction of autosis显示文摘Sodium-glucose cotransporter 2(SGLT2)inhibitors reduce cardiovascular mortality in patients with diabetes mellitus but the protective mechanism remains elusive.Here we demonstrated that the SGLT2 inhibitor,Empagliflozin(EMPA),suppresses cardiomyocytes autosis(autophagic cell death)to confer cardioprotective effects.Using myocardial infarction(Ml)mouse models with and without diabetes mellitus,EMPA treatment significantly reduced infarct size,and myocardial fibrosis,thereby leading to improved cardiac function and survival.In the context of ischemia and nutritional glucose deprivation where autosis is already highly stimulated,EMPA directly inhibits the activity of the Na^(+)/H^(+)exchanger 1(NHE1)in the cardiomyocytes to regulate excessive autophagy.Knockdown of NHE1 significantly rescued glucose deprivation-induced autosis.In contrast,overexpression of NHE1 aggravated the cardiomyocytes death in response to starvation,which was effectively rescued by EMPA treatment.Furthermore,in vitro and in vivo analysis of NHE1 and Beclin 1 knockout mice validated that EMPA s cardioprotective effects are at least in part through downregulation of autophagic flux.These findings provide new insights for drug development,specifically targeting NHE1 and autosis for ventricular remodeling and heart failure after Ml in both diabetic and non-diabetic patients.Kai Jiang Yue Xu Dandan Wang Feng Chen Zizhuo Tu Jie Qian Sheng Xu Yixiang Xu John Hwa Jian Li Hongcai Shang Yaozu Xiang 2022Protein & Cell2022,13,5:13
8Microtubule-associated deacetylase HDAC6 promotes angiogenesis by regulating cell migration in an EB1-dependent manner显示文摘Angiogenesis,a process by which the preexisting blood vasculature gives rise to new capillary vessels,is associated with a variety of physiologic and pathologic conditions.However,the molecular mechanism underlying this important process remains poorly understood.Here we show that histone deacetylase 6(HDAC6),a microtubule-associated enzyme critical for cell motility,contributes to angiogenesis by regulating the polarization and migration of vascular endothelial cells.Inhibition of HDAC6 activity impairs the formation of new blood vessels in chick embryos and in angioreactors implanted in mice.The requirement for HDAC6 in angiogenesis is corroborated in vitro by analysis of endothelial tube formation and capillary sprouting.Our data further show that HDAC6 stimulates membrane ruffling at the leading edge to promote cell polarization.In addition,microtubule end binding protein 1(EB1)is important for HDAC6 to exert its activity towards the migration of endothelial cells and generation of capillary-like structures.These results thus identify HDAC6 as a novel player in the angiogenic process and offer novel insights into the molecular mechanism governing endothelial cell migration and angiogenesis.Dengwen Li Songbo Xie Yuan Ren Lihong Huo Jinmin Gao Dandan Cui Min Liu Jun Zhou 2011Protein & Cell2011,2,2:13
9Understanding unusually high levels of peroxyacetyl nitrate(PAN) in winter in Urban Jinan,China显示文摘Peroxyacetyl nitrate(PAN), as a major secondary pollutant, has gained increasing worldwide attentions, but relevant studies in China are still quite limited. During winter of 2015 to summer of 2016, the ambient levels of PAN were measured continuously by an automatic gas chromatograph equipped with an electron capture detector(GC–ECD) analyzer at an urban site in Jinan(China), with related parameters including concentrations of O3, NO, NO_2, PM_(2.5), HONO,the photolysis rate constant of NO_2 and meteorological factors observed concurrently. The mean and maximum values of PAN concentration were(1.89 ± 1.42) and 9.61 ppbv respectively in winter, and(2.54 ± 1.44) and 13.47 ppbv respectively in summer. Unusually high levels of PAN were observed during severe haze episodes in winter, and the formation mechanisms of them were emphatically discussed. Study showed that high levels of PAN in winter were mainly caused by local accumulation and strong photochemical reactions during haze episodes, while mass transport played only a minor role. Accelerated photochemical reactions(compared to winter days without haze) during haze episodes were deduced by the higher concentrations but shorter lifetimes of PAN, which was further supported by the sufficient solar radiation in the photolysis band along with the high concentrations of precursors(NO_2, VOCs) and HONO during haze episodes. In addition, significant PAN accumulation during calm weather of haze episodes was verified by meteorological data.Lu Liu Xinfeng Wang Jianmin Chen Likun Xue Wenxing Wang Liang Wen Dandan Li Tianshu Chen 2018Journal of Environmental Sciences2018,30,9:10
10Genome-wide association analysis identified molecular markers associated with important tea flavor-related metabolites显示文摘The characteristic secondary metabolites in tea(theanine,caffeine,and catechins)are important factors contributing to unique tea flavors.However,there has been relatively little research on molecular markers related to these metabolites.Thus,we conducted a genome-wide association analysis of the levels of these tea flavor-related metabolites in three seasons.The theanine,caffeine,and catechin levels in Population 1 comprising 191 tea plant germplasms were examined,which revealed that their heritability exceeded 0.5 in the analyzed seasons,with the following rank order(highest to lowest heritabilities):(+)-catechin>(−)-gallocatechin gallate>caffeine=(−)-epicatechin>(−)-epigallocatechin-3-gallate>theanine>(−)-epigallocatechin>(−)-epicatechin-3-gallate>catechin gallate>(+)-gallocatechin.The SNPs detected by amplified-fragment SNP and methylation sequencing divided Population 1 into three groups and seven subgroups.An association analysis yielded 307 SNP markers related to theanine,caffeine,and catechins that were common to all three seasons.Some of the markers were pleiotropic.The functional annotation of 180 key genes at the SNP loci revealed that FLS,UGT,MYB,and WD40 domain-containing proteins,as well as ATP-binding cassette transporters,may be important for catechin synthesis.KEGG and GO analyses indicated that these genes are associated with metabolic pathways and secondary metabolite biosynthesis.Moreover,in Population 2(98 tea plant germplasm resources),30 candidate SNPs were verified,including 17 SNPs that were significantly or extremely significantly associated with specific metabolite levels.These results will provide a foundation for future research on important flavor-related metabolites and may help accelerate the breeding of new tea varieties.Kaixing Fang Zhiqiang Xia Hongjian Li Xiaohui Jiang Dandan Qin Qiushuang Wang Qing Wang Chendong Pan Bo Li Hualing Wu 2021Horticulture Research2021,8,1:10
11Vitamin B2 functionalized iron oxide nanozymes for mouth ulcer healing显示文摘Mouth ulcer is associated with inflammation and high risk of bacterial infection, which aggravates the patient's condition.Currently, there is no effective treatment for mouth ulcer. Herein, we report that vitamin-modified iron oxide nanoparticles improve the healing of mouth ulcer through anti-inflammation and antibacterial activities. We discovered that vitamin B2(VB2)modified iron oxide nanoparticles performed enhanced peroxidase-like, catalase-like, and superoxide dismutase(SOD)-like activities, acting as typical iron oxide nanozymes(IONzymes) with triad activities. In particular, VB2 modification significantly improved the SOD-like activity, thus providing a reactive oxygen species(ROS)-scavenging ability. Cellular antioxidant experiments showed that vitamin B2 modified IONzymes(VB2-IONzymes) protect human oral keratinocytes(HOK) and BALB/3 T3 cells from hydrogen peroxide(H2O2), and these cells have high biocompatibility to eukaryotic cells. In addition, VB2-IONzymes exerted an antibacterial activity against Streptococcus mutans, Staphylococcus aureus, and Escherichia coli. Importantly, VB2-IONzymes accelerated the recovery of mouth ulcer and reduced the local secretion of inflammatory factors in mouse ulcer model via ROS scavenging and antibacterial activity. Taken together, our work demonstrates that vitamin B2 modification endows iron oxide nanoparticles with enhanced enzyme-like activities and VB2-IONzymes may be a promising reagent in the treatment of mouth ulcer because of their intrinsic anti-inflammation and antibacterial capabilities.Yunhao Gu Yixin Huang Zhiyue Qiu Zhuobin Xu Dandan Li Lei Chen Jing Jiang Lizeng Gao 2020Science China(Life Sciences)2020,63,1:10
12Defined tumor antigen-specific T cells potentiate personalized TCR-T cell therapy and prediction of immunotherapy response显示文摘Personalized immunotherapy targeting tumor-specific antigens(TSAs)could generate efficient and safe antitumor immune response without damaging normal tissues.Although neoantigen vaccines have shown therapeutic effect in clinic trials,precise prediction of neoantigens from tumor mutations is still challenging.The host antitumor immune response selects and activates T cells recognizing tumor antigens.Hence,T cells engineered with T-cell receptors(TCRs)from these naturally occurring tumor antigen-specific T(Tas)cells in a patient will target personal TSAs in his/her tumor.To establish such a personalized TCR-T cell therapy,we comprehensively characterized T cells in tumor and its adjacent tissues by single-cell mRNA sequencing(scRNA-seq),TCR sequencing(TCR-seq)and in vitro neoantigen stimulation.Compared to bystander T cells circulating among tissues,Tas cells were characterized by tumor enrichment,tumor-specific clonal expansion and neoantigen specificity.We found that CXCL13 is a unique marker for both CD4^(+)and CD8^(+)Tas cells.Importantly,TCR-T cells expressing TCRs from Tas cells showed significant therapeutic effects on autologous patient-derived xenograft(PDX)tumors.Intratumoral Tas cell levels measured by CXCL13 expression precisely predicted the response to immune checkpoint blockade,indicating a critical role of Tas cells in the antitumor immunity.We further identified CD200 and ENTPD1 as surface markers for CD4^(^(+))and CD8^(^(+))Tas cells respectively,which enabled the isolation of Tas cells from tumor by Fluorescence Activating Cell Sorter(FACS)sorting.Overall,our results suggest that TCR-T cells engineered with Tas TCRs are a promising agent for personalized immunotherapy,and intratumoral Tas cell levels determine the response to immunotherapy.Jingjing He Xinxin Xiong Han Yang Dandan Li Xuefei Liu Shuo Li Shuangye Liao Siyu Chen Xizhi Wen Kuai Yu Lingyi Fu Xingjun Dong Kaiyu Zhu Xiaojun Xia Tiebang Kang Chaochao Bian Xiang Li Haiping Liu Peirong Ding Xiaoshi Zhang Zhenjiang Liu Wende Li Zhixiang Zuo Penghui Zhou 2022Cell Research2022,32,6:10

16Primarily screening and analyzing ESTs differentially expressed in rats' primary liver cancer显示文摘Objective: To screen and analyze key express sequence tags (ESTs) which were differentially displayed in every period of SD rats' primary hepatic carcinoma and reveal the molecular mechanism of carcinogenesis. Methods: Using diethylnitrosamine (DENA) as a cancerigenic agent, animal models with different phases of primary hepatic cancer were constructed in SD rats. Rats were respectively sacrificed at d 14, d 28, d 56, d 77, d 105 and d 112 after the rats received DENA by gavage, then the livers were harvested. One part of the livers was classified according to their pathological changes, while the other was reserved for molecular mechanism studies on hepatocarcinogenesis. The differentially expressed genes were isolated from both normal and morbid tissues by mRNA differential display technique (DDRT-PCR). After the fragments were sequenced, bioinformatics were used to analyze the results. Results: Twelve differentially expressed cDNA fragments were obtained. Nine fragments had the homology with known cDNA clones, especially EST-7 was similar to BN/SsNHsdMCW mitochondrion gene and the identity was 100% which suggested EST-7 may be the part of BN/SsNHsdMCW mitochondrion gene. In contrast, other three fragments (EST-1, EST-3 and EST-5) had extremely low identity to any genes registered in GENBANK databases. Conclusions: BN/SsNHsdMCW mitochondrion gene was expressed in different periods of hepatocarcinogenesis. Moreover, EST-1, EST-3 and EST-5 were suggested to contribute to the development of rat hepatocarcinogenesis, and thus may be candidates of new targets of oncogenes or cancer suppressor genes.Dandan Liu Lijuan Zhi Mingxia Ma Dan Qiao Meijuan Wang Yawei Wang Baijie Jin Anqi Li Guting Liu Yiqing Zhang Yanyan Song Hongxu Zhang 2013Chinese Journal of Cancer Research2013,25,1:9

18Improved film evaporator for mechanistic understanding of microwave-induced separation process显示文摘Microwave-induced film evaporation separation process has been reported recently to separate the polar/nonpolar mixture.However,the efficiency of the separation is still too low for practical applications,which requires further enhancement via different strategies such as optimization design of evaporator structure.In addition the depth understanding of the separation mechanisms is great importance for better utilization of the microwaveinduced separation process.To carry out these investigations,a novel microwave-induced falling film evaporation instrument was developed in this paper.The improvement of the enhancement effect of microwave-induced separation was observed based on the improved film evaporator.The systematic experiments on microwave-induced separation with different binary azeotropic mixtures(ethanol-ethyl acetate system and dimethyl carbonate(DMC)-H20 system)were conducted based on the new evaporator.For the ethanol-ethyl acetate system,microwave irradiation shifted the direction of evaporation separation at higher ethanol content in the starting liquid mixture.Moreover,for DMC-H20 system microwaveinduced separation process broke through the limitations of the traditional distillation process.The results clearly demonstrated the microwave-induced evaporation separation process could be commendably applied to the separation of binary azeotrope with different dielectric properties.Effects of operating parameters are also investigated to trigger further mechanism understanding on the microwave-induced separation process.Xin Gao Dandan Shu Xingang Li Hong Li 2019Frontiers of Chemical Science and Engineering2019,13,4:7
19Assembling of a novel 3D Ag(Ⅰ)-MOFs with mixed ligands tactics:Syntheses, crystal structure and catalytic degradation of nitrophenol显示文摘A silver-based metal-organic framework(Ag-MOFs), [Ag2(H3 ddcba)(dpp)2](1)(H5 ddcba = 3,5-(di(2',5'-dicarboxylphenyl)benozoic acid, dpp = 1,3-di(4-pyridyl)propane), was successfully constructed via hydrothermal assembly of a pentacaboxylate ligand, a N-donor ligand and Ag(I) ions, which possesses a pcu topology and exhibits excellent catalytic properties in aqueous solution for the degradation of onitrophenol(2-NP), m-nitrophenol(3-NP) and p-nitrophenol(4-NP). Related kinetics of such catalytic reactions, photoluminescent and thermal stability of compound 1 were also investigated.Dandan Huang Xueqian Wua Junwu Tian Xiaokun Wang Zhihang Zhou Dongsheng Li 2018Chinese Chemical Letters2018,29,6:7
