| 1 | Clinical 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 | 2020 | Science China(Life Sciences)2020，63，3： | 157 |
| 2 | Functional exhaustion of antiviral lymphocytes in COVID-19 patients显示文摘In December 2019,a novel coronavirus was first reported in Wuhan,China.1 It was named by the World Health Organization as severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)and is responsible for coronavirus disease 2019(COVID-19).Up to 28 February 2020,79,394 cases have been confirmed according to China’s National Health Commission.Outside China,the virus has spread rapidly to over 36 countries and territories. | Yuanhong Xuand Zhigang Tian Meijuan Zheng Yong Gao Gang Wang Guobin Song Siyu Liu Dandan Sun Yuanhong Xu Zhigang Tian | 2020 | Cellular & Molecular Immunology2020，17，5： | 54 |
| 3 | Identification and expansion of cancer stem cells in tumor tissues and peripheral blood derived from gastric adenocarcinoma patients显示文摘胃的癌症是世界范围的第四很普通的癌症,与死亡的高率和低 5 年的幸存率。迄今为止,有为胃的癌症的有效治疗学的协议的缺乏。最近的研究建议癌症干细胞(CSC ) 为肿瘤开始,侵略,转移,和抵抗负责到 anticancer 治疗。因此,指向胃的 CSC 的治疗是吸引人的。然而,在人的胃的腺癌(GAC ) 的 CSC 没被描述。这里,我们从 GAC 病人在肿瘤纸巾和外部血识别 CSC。从肿瘤纸巾和病人的外部血被孤立的人的 GAC (GCSC ) 的 CSC 带了 CD44 和 CD54 表面标记,当注入了 immunodeficient 老鼠时,高度类似于原来的人的肿瘤的产生肿瘤,在 vitro 区分了进胃的上皮的房间,并且在 vivo 并且在 vitro 自我更新。我们的调查结果建议有效治疗学的协议必须指向 GCSC。从 GAC 病人的循环的 GCSC 的俘获也为为肿瘤转移潜在地负责的一张批评房间人口的鉴定显示出大潜力,并且为早诊断并且胃的癌症的纵的监视提供一个有效协议。 | Tie Chen Kun Yang Jianhua Yu Wentong Meng Dandan Yuan Feng Bi Fang Liu Jie Liu Bing Dai Xinzu Chen Fang Wang Fan Zeng Hong Xu Jiankun Hu Xianming Mo | 2012 | Cell Research2012，22，1： | 50 |

| 5 | Herbal 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 | 2019 | Science China(Life Sciences)2019，62，3： | 26 |
| 6 | Surveillance, epidemiology, and pathogen spectrum of hand, foot, and mouth disease in mainland of China from 2008 to 2017显示文摘Hand,foot and mouth disease(HFMD)was reported in May 2,2008 to be the 38th legally notifiable disease in China's National Notifiable Disease Reporting and Surveillance System.In order to solve the infection,an extensive three-level HFMD surveillance laboratory network was established.In this study,the framework of that network is assessed and the incidence of HFMD in China from 2008 to 2017 is reported using a descriptive epidemiologic method.During these 10 years,a series of techniques have been widely applied in all the network laboratories.Using information and material obtained from the network,a virus bank and database containing 18,238 viruses were established.Nationally,18,184,834 HFMD cases,including 152,436 severe cases and 3633 fatal cases,were reported in mainland of China.The average annual incidence in the population was 133.99/100,000 people,with a maximum incidence of 205.06/100,000 people in 2014.The incidence and mortality rates of HFMD were the highest in children aged 1–2 years.The numbers of reported cases fluctuated,with a high incidence observed every 2 years.An overall increase in the number of reported cases was also observed throughout the study period.Despite this,the incidence of severe cases and the mortality rate have been decreasing.High-risk regions are located in southern,eastern,and central China.Two peaks of HFMD infection cases were observed annually except for Northeast China.Different proportions of enterovirus serotypes were observed during the studied years.The predominant enterovirus varies from year to year,but the disease severity is always closely related to the specific serotype.EV-A71 is the dominant serotype associated with severe and fatal cases,with constituent ratios of 70.03%and 92.23%,respectively.The studied highly sensitive and efficient surveillance network provides information that is critical for prevention and control of the disease.It is extremely necessary and important to continuously conduct extensive virological surveillance for HFMD. | Tianjiao Ji Taoli Han Xiaojuan Tan Shuangli Zhu Dongmei Yan Qian Yang Yang Song Aili Cui Yan Zhang Naiying Mao Songtao Xu Zhen Zhu Dandan Niu Yong Zhang Wenbo Xu | 2019 | Biosafety and Health2019，1，1： | 26 |
| 7 | Plant-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 | 2019 | Science China(Life Sciences)2019，62，3： | 21 |
| 8 | Gain-of-function mutant p53 in cancer progression and therapy显示文摘p53 is a key tumor suppressor,and loss of p53 function is frequently a prerequisite for cancer development.The p53 gene is the most frequently mutated gene in human cancers;p53 mutations occur in>50%of all human cancers and in almost every type of human cancers.Most of p53 mutations in cancers are missense mutations,which produce the full-length mutant p53(mutp53)protein with only one amino acid difference from wild-type p53 protein.In addition to loss of the tumor-suppressive function of wild-type p53,many mutp53 proteins acquire new oncogenic activities independently of wild-type p53 to promote cancer progression,termed gain-of-function(GOF).Mutp53 protein often accumulates to very high levels in cancer cells,which is critical for its GOF.Given the high mutation frequency of the p53 gene and the GOF activities of mutp53 in cancer,therapies targeting mutp53 have attracted great interest.Further understanding the mechanisms underlying mutp53 protein accumulation and GOF will help develop effective therapies treating human cancers containing mutp53.In this review,we summarize the recent advances in the studies on mutp53 regulation and GOF as well as therapies targeting mutp53 in human cancers. | Cen Zhang Juan Liu Dandan Xu Tianliang Zhang Wenwei Hu Zhaohui Feng | 2020 | Journal of Molecular Cell Biology2020，12，9： | 18 |
| 9 | Cardioprotective 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 | 2022 | Protein & Cell2022，13，5： | 13 |
| 10 | Vitamin 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 | 2020 | Science China(Life Sciences)2020，63，1： | 10 |
| 11 | Allele-aware chromosome-level genome assembly of Artemisia annua reveals the correlation between ADS expansion and artemisinin yield显示文摘Artemisia annua is the major natural source of artemisinin,an anti-malarial medicine commonly used worldwide.Here,we present chromosome-level haploid maps for two A.annua strains with different artemisinin contents to explore the relationships between genomic organization and artemisinin production.High-fidelity sequencing,optical mapping,and chromatin conformation capture sequencing were used to assemble the heterogeneous and repetitive genome and resolve the haplotypes of A.annua.Approximately 5o,ooo genes were annotated for each haplotype genome,and a triplication event that occurred approximately 58.12million years ago was examined for the first time in this species.A total of 3,903,467-5,193,414 variants(SNPs,indels,and structural variants)were identified in the 1.5-Gb genome during pairwise comparison between haplotypes,consistent with the high heterozygosity of this species.Genomic analyses revealed a correlation between artemisinin concents and the copy number of amorpha-4,11-dienes ynthasegenes.This correlation was further confirmed by resequencing of 36A.annua samples with varied artemisinin contents.Circular consensus sequencing of transcripts facilitated the detection of paralog expression.Collectively,our study provides chromosome-level allele-aware genome assemblies for two A.annua strains and new insights into the biosynthesis of artemisinin and its regulation,which will contribute to conquering malaria worldwide. | Baosheng Liao Xiaofeng Shen Li Xiang Shuai Guo Shiyu Chen Ying Meng Yu Liang Dandan Ding Junqi Bai Dong Zhang Tomasz Czechowski Yi Li Hui Yao Tingyu Mai Caroline Howard Chao Sun Haitao Liu Jiushi Liu Jin Pei Jihai Gao Jigang Wang Xiaohui Qiu Zhihai Huang Hongyi Li Ling Yuan Jianhe Wei lan Graham Jiang Xu Boli Zhang Shilin Chen | 2022 | Molecular Plant2022，15，8： | 9 |

| 13 | miR164c and miR168a regulate seed vigor in rice^∞显示文摘Micro RNAs(miRNAs)are key regulators of gene expression in many important biological processes of plants.However,few miRNAs have been shown to regulate seed vigor.Here,we conducted microarray assays to analyze miRNA expression levels in seeds of the rice(Oryza sativa L.)cultivar ZR02.Results showed significant differences in the expression of 11 miRNAs between artificially aged and untreated control seeds.Among these,osa-miR164c was transcriptionally upregulated,while osamiR168 a was downregulated in artificially aged seeds;this was verified by quantitative real-time PCR analysis.Under the same aging condition,osa-miR164c overexpression in OE164c transgenic seeds and osa-miR168a silencing in MIM168a transgenic seeds of the rice cultivar Kasalath led to lower germination rates,whereas osa-miR164c silencing Rin MIM164c and osa-miR168a overexpression in OE168a resulted in higher seed germination rates compared with wild-type seeds.Meanwhile,changes in cytomembrane permeability of seeds and in the expression level of osa-miR164c target genes(OsPM27 and OsPSK5)and osamiR168a target genes(OsAGO1 and OsPTR2)under aging conditions coincided with changes in seed vigor induced by osa-miR164c and osa-miR168 a.Thus,genetic manipulation of miRNAs has important implications in the development of crop cultivars with high vigor and extended life span of seeds. | Yan Zhou Shiqi Zhou Liping Wang Duo Wu Hailan Cheng Xu Du Dandan Mao Chunlai Zhang Xiaocheng Jiang | 2020 | Journal of Integrative Plant Biology2020，62，4： | 7 |
| 14 | Characterization of flavor fingerprinting of red sufu during fermentation and the comparison of volatiles of typical products显示文摘Traditional Chinese red sufu is a popular condiment,and typical flavor is an important indicator of sensory qualities in commercial products.In this study,the volatile aroma analysis of Wangzhihe red sufu(WRS)from different fermentation stages and four typical red sufu products from different locations was carried out by gas chromatography-mass spectrometry(GC–MS),gas chromatography-mass spectrometry/olfactory(GC–MS/O),electronic nose(E-nose)and sensory evaluation.Results showed that 106 volatile compounds were identified in Wangzhihe red sufu during fermentation process,in which phenolics and alcohols were dominant at molded and salted phetze stages,while esters and alcohols became predominate at post-fermentation stage.The volatile aroma substances varied at each fermentation stage.Furthermore,86 volatiles,including 16 aroma-active compounds,were detected in four typical red sufu products.The multivariate analysis results showed the difference in samples from different fermentation stages and typical red sufu products according to GC–MS and E-nose analysis.Combined with flavor omics,discriminant model was established for effective discrimination of samples from different fermentation stages and locations,as well as references to sufu maturity extent.The study presented a new strategy for quality evaluation of red sufu,which could be the supplement to quality evaluation standards. | Peng Wang Xiaoran Ma Wenping Wang Dandan Xu Xin Zhang Jian Zhang Yong Sun | 2019 | Food Science and Human Wellness2019，8，4： | 7 |

| 17 | Ascorbic acid accelerates Wallerian degeneration after peripheral nerve injury显示文摘Wallerian degeneration occurs after peripheral nerve injury and provides a beneficial microenvironment for nerve regeneration.Our previous study demonstrated that ascorbic acid promotes peripheral nerve regeneration,possibly through promoting Schwann cell proliferation and phagocytosis and enhancing macrophage proliferation,migration,and phagocytosis.Because Schwann cells and macrophages are the main cells involved in Wallerian degeneration,we speculated that ascorbic acid may accelerate this degenerative process.To test this hypothesis,400 mg/kg ascorbic acid was administered intragastrically immediately after sciatic nerve transection,and 200 mg/kg ascorbic acid was then administered intragastrically every day.In addition,rat sciatic nerve explants were treated with 200μM ascorbic acid.Ascorbic acid significantly accelerated the degradation of myelin basic protein-positive myelin and neurofilament 200-positive axons in both the transected nerves and nerve explants.Furthermore,ascorbic acid inhibited myelin-associated glycoprotein expression,increased c-Jun expression in Schwann cells,and increased both the number of macrophages and the amount of myelin fragments in the macrophages.These findings suggest that ascorbic acid accelerates Wallerian degeneration by accelerating the degeneration of axons and myelin in the injured nerve,promoting the dedifferentiation of Schwann cells,and enhancing macrophage recruitment and phagocytosis.The study was approved by the Southern Medical University Animal Care and Use Committee(approval No.SMU-L2015081)on October 15,2015. | Lixia Li Yizhou Xu Xianghai Wang Jingmin Liu Xiaofang Hu Dandan Tan Zhenlin Li Jiasong Guo | 2021 | Neural Regeneration Research2021，16，6： | 6 |
| 18 | Arabidopsis ANAC092 regulates auxin-mediated root development by binding to the ARF8 and PIN4 promoters显示文摘Auxin is an important plant hormone that is essential for growth and development due to its effects on organogenesis, morphogenesis, tropisms, and apical dominance. The functional diversity of auxin highlights the importance of its biosynthesis, transport, and associated responses. In this study, we show that a NAC transcription factor, ANAC092(also named At NAC2 and ORESARA1),known to positively regulate leaf senescence and contribute to abiotic stress responses, also affects primary root development. Plants overexpressing ANAC092 had altered root meristem lengths and shorter primary roots compared with the wild-type control. Additionally, expression of the pro ANAC092::GUS was strongly induced by indole-3-acetic acid. Quantitative real-time RT-PCR(q RT-PCR) analysis revealed that the YUCCA2, PIN, and ARF expression levels were downregulated in ANAC092-overexpressing plants. Moreover, yeast one-hybrid and chromatin immunoprecipitation assays confirmed that ANAC092 binds to the promoters of AUXIN RESPONSE FACTOR 8(ARF8) and PIN-FORMED 4(PIN4). Furthermore, a dual-luciferase assay indicated that ANAC092 decreases ARF8 and PIN4 promoter activities. We also applied a CRISPR/Cas9 system to mutate ANAC092. The roots of three of the analyzed mutants were longer than normal. Collectively, our findings indicate that ANAC092 negatively affects root development by controlling the auxin pathway. | Dandan Xi Xu Chen Yuxia Wang Ruiling Zhong Jianmei He Jiabin Shen Feng Ming | 2019 | Journal of Integrative Plant Biology2019，61，9： | 6 |
| 19 | Molecular dissection of plant height QTLs using recombinant inbred lines from hybrids between common wheat (Triticum aestivum L.) and spelt wheat (Triticum spelta L.)显示文摘In wheat, plant height is an important agronomic trait, and a number of quantitative trait loci (QTLs) controlling plant height have been located. In this study, using the conditional and unconditional QTL mapping methods, combined with data from five different growth stages over two years of field trials, the developmental behavior for plant height in wheat was dissected. Nine unconditional QTLs and 8 conditional QTLs were identified, of which 6 were detected by both methods. None of the 11 QTLs was detected at all of the 5 investigated developmental stages, but 7 QTLs were detected at certain stages in both years. Further analysis identified 9 unconditional QTLs at different stages, which could explain the phenotypic variation from 4.81% to 17.35%. It was noteworthy that one major QTL designated QHt-4B-2, which was located on chromosome 4B, was detected on May 18 and 25 in both years, and its genetic contributions to plant height ranged from 13.42% to 16.13%. Moreover, of the 8 conditional QTLs identified, six were detected in both years, in the order of QHt-3B→QHt-4B-1→QHt-4B-2→QHt-4D→QHt-5A and QHt-2B expressed at the same developmental stage. The results indicate that QTL expression during plant height development is selective and in a temporal order. | LIU Gang XU ShengBao NI ZhongFu XIE ChaoJie QIN DanDan LI Jing LU LaHu ZHANG JinPing PENG HuiRu SUN QiXin | 2011 | Chinese Science Bulletin2011，56，18： | 6 |
| 20 | Elevated plasma levels of selective cytokines in COVID-19 patients reflect viral load and lung injury显示文摘A recent outbreak of pneumonia in Wuhan,China was found to be caused by a 2019 novel coronavirus(2019-nCoV or SARS-CoV-2 or HCoV-19).We previously reported the clinical features of 12 patients with2019-n Co V infections in Shenzhen,China.To further understand the pathogenesis of COVID-19 and find better ways to monitor and treat the disease caused by 2019-n Co V,we measured the levels of 48 cytokines in the blood plasma of those 12 COVID-19 patients.Thirty-eight out of the 48 measured cytokines in the plasma of 2019-n Co V-infected patients were significantly elevated compared to healthy individuals.Seventeen cytokines were linked to 2019-nCoV loads.Fifteen cytokines,namely M-CSF,IL-10,IFN-α2,IL-17,IL-4,IP-10,IL-7,IL-1 ra,G-CSF,IL-12,IFN-γ,IL-1α,IL-2,HGF and PDGF-BB,were strongly associated with the lung-injury Murray score and could be used to predict the disease severity of2019-n Co V infections by calculating the area under the curve of the receiver-operating characteristics.Our results suggest that 2019-nCoV infections trigger extensive changes in a wide array of cytokines,some of which could be potential biomarkers of disease severity of 2019-n Co V infections.These findings will likely improve our understanding of the immunopathologic mechanisms of this emerging disease.Our results also suggest that modulators of cytokine responses may play a therapeutic role in combating the disease once the functions of these elevated cytokines have been characterized. | Yingxia Liu Cong Zhang Fengming Huang Yang Yang Fuxiang Wang Jing Yuan Zheng Zhang Yuhao Qin Xiaoyun Li Dandan Zhao Shunwang Li Shuguang Tan Zhaoqin Wang Jinxiu Li Chenguang Shen Jianming Li Ling Peng Weibo Wu Mengli Cao Li Xing Zhixiang Xu Li Chen Congzhao Zhou William J Liu Lei Liu Chengyu Jiang | 2020 | National Science Review2020，7，6： | 6 |
