| 1 | Identification of a novel coronavirus causing severe pneumonia in human:a descriptive study显示文摘Background:Human infections with zoonotic coronaviruses(CoVs),including severe acute respiratory syndrome(SARS)-CoV and Middle East respiratory syndrome(MERS)-CoV,have raised great public health concern globally.Here,we report a novel batorigin CoV causing severe and fatal pneumonia in humans.Methods:We collected clinical data and bronchoalveolar lavage(BAL)specimens from five patients with severe pneumonia from Wuhan Jinyintan Hospital,Hubei province,China.Nucleic acids of the BAL were extracted and subjected to next-generation sequencing.Virus isolation was carried out,and maximum-likelihood phylogenetic trees were constructed.Results:Five patients hospitalized from December 18 to December 29,2019 presented with fever,cough,and dyspnea accompanied by complications of acute respiratory distress syndrome.Chest radiography revealed diffuse opacities and consolidation.One of these patients died.Sequence results revealed the presence of a previously unknownβ-CoV strain in all five patients,with 99.8%to 99.9%nucleotide identities among the isolates.These isolates showed 79.0%nucleotide identity with the sequence of SARS-CoV(GenBank NC_004718)and 51.8%identity with the sequence of MERS-CoV(GenBank NC_019843).The virus is phylogenetically closest to a bat SARS-like CoV(SL-ZC45,GenBank MG772933)with 87.6%to 87.7%nucleotide identity,but is in a separate clade.Moreover,these viruses have a single intact open reading frame gene 8,as a further indicator of bat-origin CoVs.However,the amino acid sequence of the tentative receptor-binding domain resembles that of SARS-CoV,indicating that these viruses might use the same receptor.Conclusion:A novel bat-borne CoV was identified that is associated with severe and fatal respiratory disease in humans. | Li-Li Ren Ye-Ming Wang Zhi-Qiang Wu Zi-Chun Xiang Li Guo Teng Xu Yong-Zhong Jiang Yan Xiong Yong-Jun Li Xing-Wang Li Hui Li Guo-Hui Fan Xiao-Ying Gu Yan Xiao Hong Gao Jiu-Yang Xu Fan Yang Xin-Ming Wang Chao Wu Lan Chen Yi-Wei Liu Bo Liu Jian Yang Xiao-Rui Wang Jie Dong Li Li Chao-Lin Huang Jian-Ping Zhao Yi Hu Zhen-Shun Cheng Un-Lin Liu Zhao-Hui Qian Chuan Qin Qi Jin Bin Cao Jian-Wei Wang | 2020 | Chinese Medical Journal2020,,9: | 99 |

| 3 | Fringe pattern analysis using deep learning显示文摘In many optical metrology techniques,fringe pattern analysis is the central algorithm for recovering the underlying phase distribution from the recorded fringe patterns.Despite extensive research efforts for decades,how to extract the desired phase information,with the highest possible accuracy,from the minimum number of fringe patterns remains one of the most challenging open problems.Inspired by recent successes of deep learning techniques for computer vision and other applications,we demonstrate for the first time,to our knowledge,that the deep neural networks can be trained to perform fringe analysis,which substantially enhances the accuracy of phase demodulation from a single fringe pattern.The effectiveness of the proposed method is experimentally verified using carrier fringe patterns under the scenario of fringe projection profilometry.Experimental results demonstrate its superior performance,in terms of high accuracy and edge-preserving,over two representative single-frame techniques:Fourier transform profilometry and windowed Fourier transform profilometry. | Shijie Feng Qian Chen Guohua Gu Tianyang Tao Liang Zhang Yan Hu Wei Yin Chao Zuo | 2019 | Advanced Photonics2019,1,2: | 31 |

| 7 | N6-Methyladenine DNA Methylation in Japonica and Indica Rice Genomes and Its Association with Gene Expression,Plant Development, and Stress Responses显示文摘N6-Methyladenine (6mA)DNA methylation has recently been implicated as a potential new epigenetic marker in eukaryotes,including the dioot modelArabidopsis thaliana.However,the conservation and divergence of 6mA distribution patterns and functions in plants remain elusive.Here we report high-quality 6mA methylomes at single-nucleotide resolution in rice based on substantially improved genome sequences of two rice cultivars,Nipponbare (Nip;Japonica)and 93-11 (Indica).Analysis of 6mA genomic distribution and its association with transcription suggest that 6mA distribution and function is rather conserved between rice and Arabidopsis.We found that 6mA levels are positively correlated with the expression of key stressrelated genes,which may be responsible for the difference in stress tolerance between Nip and 93-11. Moreover,we showed that mutations in DDM1 cause defects in plant growth and decreased 6mA level. Our results reveal that 6mA is a conserved DNA modification that is positively associated with gene expression and contributes to key agronomic traits in plants. | Qian Zhang Zhe Liang Xuean Cui Changmian Ji Yun Li Pingxian Zhang Jingrong Liu Adeel Riaz Pu Yao Min Liu Yunpeng Wang Tiegang Lu Hao Yu Donglei Yang Hongkun Zheng Xiaofeng Gu | 2018 | Molecular Plant2018,11,12: | 18 |
| 8 | Effect of exposure to ambient PM2.5 pollution on the risk of respiratory tract diseases: a meta-analysis of cohort studies显示文摘The International Agency for Research on Cancer and the World Health Organization have designated airborne particulates,including particulates of median aerodynamic diameter < 2.5um(PM_(2.5)),as Group 1 carcinogens.It has not been determined,however,whether exposure to ambient PM_(2.5) is associated with an increase in respiratory related diseases.This meta-analysis assessed the association between exposure to ambient fine particulate matter(PM_(2.5)) and the risk of respiratory tract diseases,using relevant articles extracted from PubMed,Web of Science,and Embase.In results,of the 1,126 articles originally identified,35(3.1%) were included in this meta-analysis.PM_(2.5)was found to be associated with respiratory tract diseases.After subdivision by age group,respiratory tract disease,and continent,PM_(2.5) was strongly associated with respiratory tract diseases in children,in persons with cough,lower respiratory illness,and wheezing,and in individuals from North America,Europe,and Asia.The risk of respiratory tract diseases was greater for exposure to traffic-related than non-traffic-related air pollution.In children,the pooled relative risk(RR) represented significant increases in wheezing(8.2%),cough(7.5%),and lower respiratory illness(15.3%).The pooled RRs in children were 1.091(95%CI:1.049,1.135) for exposure to<25 μg/m^3 PM_(2.5),and 1.126(95%CI:1.067,1.190) for exposure to > 25 μg/m^3 PM_(2.5).In conclusion,exposure to ambient PM_(2.5) was significantly associated with the development of respiratory tract diseases,especially in children exposed to high concentrations of PM_(2.5). | Qian Liu Cheng Xu Guixiang Ji Hui Liu Wentao Shao Chunlan Zhang Aihua Gu Peng Zhao | 2017 | The Journal of Biomedical Research2017,31,2: | 16 |

| 10 | Addition of prokinetics to PPI therapy in gastroesophageal reflux disease:A meta-analysis显示文摘AIM:To investigate the efficacy of adding prokinetics to proton pump inhibitors(PPIs)for the treatment of gastroesophageal reflux disease(GERD).METHODS:PubMed,Cochrane Library,and Web of Knowledge databases(prior to October 2013)were systematically searched for randomized controlled trials(RCTs)that compared therapeutic efficacy of PPI alone(single therapy)or PPI plus prokinetics(combined therapy)for GERD.The primary outcome of those selected trials was complete or partial relief of non-erosive reflux disease symptoms or mucosal healing in erosive reflux esophagitis.Using the test of heterogeneity,we established a fixed or random effects model where the risk ratio was the primary readout for measuring efficacy.RESULTS:Twelve RCTs including 2403 patients in total were enrolled in this study.Combined therapy was not associated with significant relief of symptoms or alterations in endoscopic response relative to single therapy(95%CI:1.0-1.2,P=0.05;95%CI:0.66-2.61,P=0.44).However,combined therapy was associated with a greater symptom score change(95%CI:2.14-3.02,P<0.00001).Although there was a reduction in the number of reflux episodes in GERD[95%CI:-5.96-(-1.78),P=0.0003]with the combined therapy,there was no significant effect on acid exposure time(95%CI:-0.37-0.60,P=0.65).The proportion of patients with adverse effects undergoing combined therapy was significantly higher than for PPI therapy alone(95%CI:1.06-1.36,P=0.005)when the difference between 5-HT receptor agonist and PPI combined therapy and single therapy(95%CI:0.84-1.39,P=0.53)was excluded.CONCLUSION:Combined therapy may partially improve patient quality of life,but has no significant effect on symptom or endoscopic response of GERD. | Li-Hua Ren Wei-Xu Chen Li-Juan Qian Shuo Li Min Gu Rui-Hua Shi | 2014 | World Journal of Gastroenterology2014,20,9: | 14 |

| 12 | PARylation regulates stress granule dynamics, phase separation, and neurotoxicity of disease-related RNA-binding proteins显示文摘Mutations in RNA-binding proteins (RBPs) localized in ribonucleoprotein (RNP) granules, such as hnRNP A1 and TDP-43, promote aberrant protein aggregation, which is a pathological hallmark of various neurodegenerative diseases, such as amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Protein posttranslational modifications (PTMs) are known to 佗gulate RNP granules. In this study, we investigate the function of poly(ADP-ribosyl)ation (PARylation), an important PTM involved in DNA damage repair and cell death, in RNP granule-related neurodegeneration. We reveal that PARylation levels are a major regulator of the assembly-disassembly dynamics of RNP granules containing disease-related RBPs, hnRNP A1 and TDP-43. We find that hnRNP A1 can both be PARylated and bind to PARylated proteins or poly(ADP-ribose)(PAR). We further uncover that PARylation of hnRNP A1 at K298 controls its nucleocytoplasmic transport, whereas PAR-binding via the PAR-binding motif (PBM) of hnRNP Al regulates its association with stress granules. Moreover, we reveal that PAR not only dramatically enhances the liquid-liquid phase separation of hnRNP A1, but also promotes the co-phase separation of hnRNP A1 and TDP-43 in vitro and their interaction in vivo. Finally, both genetic and pharmacological inhibition of PARP mitigates hnRNP Al- and TDP-43-mediated neurotoxicity in cell and Drosophila models of ALS. Together, our findings suggest a novel and crucial role for PARylation in regulating the dynamics of RNP granules, and that dysregulation in PARylation and PAR levels may con tribute to ALS disease pathoge nesis by promoting protei n aggregation. | Yongjia Duan Aiying Du Jinge Gu Gang Duan Chen Wang Xinrui Gui Zhiwei Ma Beituo Qian Xue Deng Kai Zhang Le Sun Kuili Tian Yaoyang Zhang Hong Jiang Cong Liu Yanshan Fang | 2019 | Cell Research2019,29,3: | 13 |
| 13 | A novel compound AB38b attenuates oxidative stress and ECM protein accumulation in kidneys of diabetic mice through modulation of Keap1/Nrf2 signaling显示文摘Extracellular matrix(ECM)deposition following reactive oxygen species(ROS)overproduction has a key role in diabetic nephropathy(DN),thus,antioxidant therapy is considered as a promising strategy for treating DN.Here,we investigated the therapeutic effects of AB38b,a novel syntheticα,β-unsaturated ketone compound,on the oxidative stress(OS)and ECM accumulation in type 2 diabetes mice,and tried to clarify the mechanisms underlying the effects in high glucose(HG,30 mM)-treated mouse glomerular mesangial cells(GMCs).Type 2 diabetes model was established in mice with high-fat diet feeding combined with streptozocin intraperitoneal administration.The diabetic mice were then treated with AB38b(10,20,40 mg·kg^?1·d^?1,ig)or a positive control drug resveratrol(40 mg·kg^?1·d^?1,ig)for 8 weeks.We showed that administration of AB38b or resveratrol prevented the increases in malondialdehyde level,lactate dehydrogenase release,and laminin and type IV collagen deposition in the diabetic kidney.Simultaneously,AB38b or resveratrol markedly lowered the level of Keap1,accompanied by evident activation of Nrf2 signaling in the diabetic kidney.The underlying mechanisms of antioxidant effect of AB38b were explored in HG-treated mouse GMCs.AB38b(2.5?10μM)or resveratrol(10μM)significantly alleviated OS and ECM accumulation in HG-treated GMCs.Furthermore,AB38b or resveratrol treatment effectively activated Nrf2 signaling by inhibiting Keap1 expression without affecting the interaction between Keap1 and Nrf2.Besides,AB38b treatment effectively suppressed the ubiquitination of Nrf2.Taken together,this study demonstrates that AB38b ameliorates experimental DN through antioxidation and modulation of Keap1/Nrf2 signaling pathway. | Lei Du Lei Wang Bo Wang Jin Wang Meng Hao Yi-bing Chen Xi-zhi Li Yuan Li Yan-fei Jiang Cheng-cheng Li Hao Yang Xiao-ke Gu Xiao-xing Yin Qian Lu | 2020 | Acta Pharmacologica Sinica2020,41,3: | 13 |
| 14 | Development of gene-tagged molecular markers for starch synthesis-related genes in rice显示文摘Improving grain quality is an important goal in breeding new elite rice varieties,requiring effective tools for the identification of target genotypes.Molecular marker-aided selection(MAS),combined with conventional breeding approaches,enables us to pre-cisely identify the individual genotypes that are associated with different grain quality features,which can dramatically improve the breeding efficiency.However,to date,the number of molecular markers used in MAS for grain quality improvement is still somewhat limited.In this study,based on our previous study that rice grain quality is strongly associated with starch synthesis in the endosperm,we developed 51 gene-tagged molecular markers according to sequence variations in 18 starch synthesis-related genes from 16 typical rice cultivars.These markers can discriminate the different alleles among rice germplasms.These novel markers will provide effective tools in improving grain quality via the breeding new elite rice varieties. | TIAN ZhiXi YAN ChangJie QIAN Qian YAN Song XIE HuiLan WANG Fang XU JieFen LIU GuiFu WANG YongHong LIU QiaoQuan TANG ShuZhu LI JiaYang GU MingHong | 2010 | Chinese Science Bulletin2010,55,33: | 12 |
| 15 | Restorative effect and mechanism of mecobalamin on sciatic nerve crush injury in mice显示文摘Mecobalamin,a form of vitamin B12 containing a central metal element(cobalt),is one of the most important mediators of nervous system function.In the clinic,it is often used to accelerate recovery of peripheral nerves,but its molecular mechanism remains unclear.In the present study,we performed sciatic nerve crush injury in mice,followed by daily intraperitoneal administration of mecobalamin(65 μg/kg or 130 μg/kg) or saline(negative control).Walking track analysis,histomorphological examination,and quantitative real-time PCR showed that mecobalamin significantly improved functional recovery of the sciatic nerve,thickened the myelin sheath in myelinated nerve fibers,and increased the cross-sectional area of target muscle cells.Furthermore,mecobalamin upregulated m RNA expression of growth associated protein 43 in nerve tissue ipsilateral to the injury,and of neurotrophic factors(nerve growth factor,brain-derived nerve growth factor and ciliary neurotrophic factor) in the L4–6 dorsal root ganglia.Our findings indicate that the molecular mechanism underlying the therapeutic effect of mecobalamin after sciatic nerve injury involves the upregulation of multiple neurotrophic factor genes. | Lin Gan Minquan Qian Keqin Shi Gang Chen Yanglin Gu Wei Du Guoxing Zhu | 2014 | Neural Regeneration Research2014,9,22: | 11 |
| 16 | Enhanced N-doping in mesoporous carbon for efficient electrocatalytic CO2 conversion显示文摘The capability of electrocatalytic reducti on of carbon dioxide(CO2)using nitrogen(N)-doped carb on strongly depe nds on the N-dopi ng level and their types.In this work,we developed a strategy to generate mesoporous N-doped carb on frameworks with tun able configurati ons and contents of N dopants,by using a secondary doping process via the treatment of N,N-dimethylformamide(DMF)solvent.The obtained mesoporous N-doped carbon(denoted as MNC-D)served as an efficient electrocatalyst for electroreduction of CO2 to CO.A high Faradaic efficiency of^92%and a partial current density for CO of-6.8 mA·cm^-2 were achieved at a potential of-0.58 V vs.RHE.Electrochemical analyses further revealed that the active sites within the N-doped carb on catalysts were the pyridinic N and defects gen erated by the DMF treatme nt,which enhan ced the activati on and adsorpti on CO2 molecules.Our study suggests a new approach to develop efficie nt carb on-based catalysts for potential scalable CO2 reduction reaction(CO2RR)to fuels and chemicals. | Min Kuang Anxiang Guan Zhengxiang Gu Peng Han Linping Qian Gengfeng Zheng | 2019 | Nano Research2019,12,9: | 11 |
| 17 | ELE restrains empty glumes from developing into lemmas显示文摘Although there is evident homology among reproductive organs when comparing Poaceae (grass) and eudicots, the identity of grass specific organs, such as lodicules, palea, lemma, and glumes has been the subject of a vast and largely inconclusive discussion. Here we provide some direct evidence to support the idea that the empty glumes of rice (Oryza sativa) are counterparts of lemmas. We show that the development of empty glumes is regulated by ELE (elongated empty glume), which belongs to a plant specific novel gene family. Mutations at the ELE locus cause elongated empty glumes, which mimic the lemmas and have the epidermal morphology of lemmas with four or five vascular bundles. As a nuclear-localized gene, ELE is specifically expressed at the empty glumes of immature spikelets, and its ectopic expression causes many floral development defects, including lemma-like palea, extra palea-like structures, elongated lodicules, extra stamens and stigmas. Our result suggests that empty glumes are lemmas of the sterile florets located at the lateral side of the rice spikelet, and ELE acts as a regulator restraining its growth to maintain its small size in wild-type plants. | Lilan Hong Qian Qian Keming Zhu Ding Tang Zejun Huang Ling Gao Ming Li Minghong Gu Zhukuan Cheng | 2010 | Journal of Genetics and Genomics2010,37,2: | 11 |
| 18 | Reconstruction of the abdominal wall by using a combination of the human acellular dermal matrix implant and an interpositional omentum flap after extensive tumor resection in patients with abdominal wall neoplasm: A preliminary result显示文摘AIM:To present our trial using a combination of the human acellular dermal matrix (HADM) implant and an interpositional omentum flap to repair giant abdominal wall defects after extensive tumor resection. METHODS:Between February and October of 2007, three patients with giant defects of the abdominal wall after extensive tumor resection underwent reconstruction with a combination of HADM and omentum flap. Postoperative morbidities and signs of herniation were monitored. RESULTS:The abdominal wall reconstruction was successful in these three patients, there was no severe morbidity and no signs of herniation in the follow-up period. CONCLUSION:The combination of HADM and omentum flap offers a new, safe and effective alternative to traditional forms in the repair of giant abdominal wall defects. Further analysis of the long-term outcome and more cases are needed to assess the reliability of this technique. | Yan Gu Rui Tang Ding-Quan Gong Yun-Liang Qian | 2008 | World Journal of Gastroenterology2008,14,5: | 10 |
| 19 | Effects of tripchlorolide on the epididymides and testes of rats显示文摘Aim: To further evaluate the antifertility effects of tripchlorolide, a derivative of triptolide produced at the extraction procedure of Tripterygium wilfordii Hook. f., in male rats and to investigate its sites and possible mechanisms of action.Methods: In male rats, tripchlorolidte was given by oral garage at a dose of 50 ug'kg^-1, d^-1 for 5 weeks, fertility wasassessed by mating tests, and biochemical indices and light microscopic obsefvation of the epididymides and testes werealso performed. Results: Administration of tripchlorolide at 50 ,ug, kg ^-1, d^-1 for 3 weeks did not influence the fertilityof male rats, but 5-week treatment rendered the rats infertile. The density and motility of spennatozoa collected fromcanda epididymides were reduced significandy. The epididymal weights, as well as the L-camitine concentration and a-glucosidase content in the epididymal fluid were decreasd. There were no significant differences in a-glucosidase andacid phosphatase (ACP) in caput epididyma/homogenatas between the control and the experimental rats. Obvioos mor-phological changes were observed in the epididymal spematozoa, mainly including head and tail separation or acrosomecurving, Sloughed speprmatids were found in the semirfifeous and epididymal tubules. In testicular homogenates,tripchlorolide had no influence on the lactate dehydrogenase-C4(LDH-C4) and hyaluronidase activities. No apparentlesions were observed in the seminiferous and epididymal epithelium. Conclusion: At the dose level employed,tripchlorolide has a significant effect on the fertility in male rats and the primary sites of actiort may be spenuatids and tes-ticular and epididymal spemmatozoa. | Zuo-Peng WANG Zhi-Ping GU Lin CAO Yang XU Gen-Di YOU Bai-Yong MAO Shao-Zhen QIAN Shanghai Institute of Materia Medical, Chinese Academy of Sciences, Shanghai 200031, China | 1999 | Asian Journal of Andrology1999,1,3: | 10 |
