1大气二氧化氮与每日总死亡率、心血管和呼吸系统疾病死亡率的短期关联:398个城市的多中心分析显示文摘目的:采用统一的分析方案,评估全球多个国家/地区的二氧化氮(NO_(2))与总死亡率、心血管和呼吸系统疾病死亡率之间的短期关联。研究设计:采用两阶段的时间序列分析方法、过度离散的广义线性模型和多水平meta分析。研究地点:22个低到高收入国家/地区的398个城市。主要结局指标:1973—2018年逐日总死亡人数(6280万人)、心血管疾病死亡人数(1970万人)和呼吸系统疾病死亡人数(550万人)。结果:平均而言,NO_(2)浓度在滞后1天(前1天)每增加10μg/m^(3),会导致总死亡率、心血管和呼吸系统疾病死亡率分别增加0.46%(95%可信区间0.36%~0.57%)、0.37%(0.22%~0.51%)、0.47%(0.21%~0.72%)。在对共污染物(PM_(10)、PM_(2.5)、臭氧、二氧化硫和一氧化碳)进行调整后,这些关联仍然很稳定。所有3种死因的暴露-反应曲线几乎是线性的,没有明显的阈值。在398个城市中,可归因于高过假定零水平的NO_(2)浓度造成的死亡比例为1.23%(95%可信区间0.96%~1.51%)。结论:这项多中心研究提供了关于NO_(2)短期暴露与总死亡率、心血管和呼吸系统死亡风险之间的独立和线性关联的关键证据,说明通过加强NO_(2)的控制和监管限制标准,可获得人群水平的健康收益。孟夏 刘聪(校) 陈仁杰 郑湃(译) 阚海东(校) Francesco Sera Ana Vicedo-Cabrera Ai Milojevic Maria Guo Yuming Tong Shilu Micheline de Sousa Zanotti Stagliorio Coelh Paulo Hilario Nascimento Saldiva Eric Lavigne Patricia Matus Correa Nicolas Valdes Ortega Samuel Osorio Garcia Jan Kysely Ales Urban Hans Orru Marek Maasikmets Jouni J K Jaakkola Niilo Ryti Veronika Huber Alexandra Schneider Klea Katsouyanni Antonis Analitis Masahiro Hashizume Yasushi Honda Chris Fook Sheng Ng Baltazar Nunes João Paulo Teixeira Iulian Horia Holobaca Simona Fratianni Ho Kim Aurelio Tobias Carmeníniguez Bertil Forsberg ChristoferÅström Martina S Ragettli Yue-Liang Leon Guo Shih-Chun Pan Shanshan Li Michelle L Bell Antonella Zanobetti Joel Schwartz Tangchun Wu Antonio Gasparrini 2021英国医学杂志中文版2021,24,8:7
2Photoperiod-and temperature-mediated control of the ethylene response and winter dormancy induction in Prunus mume显示文摘Plant dormancy is essential for perennial plant survival.Different genotypes of Prunus mume,including Eumume group and Apricot Mei group,undergo leaf senescence and dormancy at different times.In order to verify the cold resistance of P.mume,freeze resistance evaluation was carried out.Our results showed that Apricot Mei group had a stronger freezing tolerance than Eumume group and that leaf senescence and dormancy of Apricot Mei group occurred at an earlier period before winter.Based on phenotypic data in response to seasonal climate change,the significant candidate regions were selected using GWAS.Furthermore,through KEGG pathway and qRT-PCR analyses,we found that the ethylene-related genes,including PmEIL(Pm002057)and PmERF(Pm004265),were significantly upregulated in‘Songchun’Mei(Apricot Mei group)and downregulated in‘Zaohua Lve’Mei(Eumume group).Ethylene-related genes expression models showed that ethylene may be indirectly involved in the induction of dormancy.The PmEIL and PmERF genes were the core genes of the ethylene signal transduction pathway and were regulated by the exogenous ACC or PZA compounds.For non-dormant or weekly dormant perennial plants,application of ACC was able to induce plant dormancy and thus enhance cold/freeze tolerance.Overall,the expression of the major ethylene genes played a significant role in dormancy induction and freezing tolerance in P.mume;accordingly,application of ACC and PZA compounds were an effective approach for enhancing cold/freeze of tolerance of woody plant.Ping Li Tangchun Zheng Xiaokang Zhuo Man Zhang Xue Yong Lulu Li Jia Wang Tangren Cheng Qixiang Zhang 2021Horticultural Plant Journal2021,7,3:6
3Transcriptome profiles reveal that gibberellin-related genes regulate weeping traits in crape myrtle显示文摘Plant architecture includes vital traits that influence and benefit crops,and economically important trees.Different plant architectures provide natural beauty.Weeping ornamental plants are aesthetically appealing to people.The regulatory mechanism controlling the weeping trait is poorly understood in crape myrtle.To investigate the weeping trait mechanism,transcriptional profiling of different organs in weeping and upright crape myrtle was performed based on phenotype.Phenotypic and histological analyses demonstrated that endodermal cells were absent,and that new shoot phenotypes could be rescued by the GA3 treatment of weeping plants.The transcriptional analysis and coexpression network analysis(WGCNA)of differentially expressed genes indicated that GA synthesis and signal transduction pathways play a role in weeping traits.When the expression level of a negative element of GA signaling,LfiGRAS1,was reduced by virus-induced gene silencing(VIGS),new branches grew in infected plants in a negatively geotropic manner.An integrated analysis implied that GA had a strong influence on weeping crape myrtle by interacting with other factors.This study helps to elucidate the mechanism governing the weeping trait and can improve the efficiency of breeding in Lagerstroemia.Suzhen Li Tangchun Zheng Xiaokang Zhuo Zhuojiao Li Lulu Li Ping Li Like Qiu Huitang Pan Jia Wang Tangren Cheng Qixiang Zhang 2020Horticulture Research2020,7,1:5
4Two novel eukaryotic translation initiation factor 5A genes from Populus simonii×P.nigra confer tolerance to abiotic stresses in Saccharomyces cerevisiae显示文摘The role of plant e IF5 A proteins in multiple biological processes, such as protein synthesis regulation,translation elongation, m RNA turnover, programmed cell death and stress tolerance is well known. Toward using these powerful proteins to increase stress tolerance in agricultural plants, in the present study, we cloned and characterized Psne IF5A2 and Psne IF5A4 from young poplar(P. simonii 9 P. nigra) leaves. The deduced amino acid sequences of Psne IF5A2 and Psne IF5A4 were 98 %similar to each other, and they are orthologs of e IF5A1 in Arabidopsis. In a subcellular localization analysis,Psne IF5A2 and Psne IF5A4 proteins were localized in the nucleus and cytoplasm. q RT-PCR analysis showed that Psne IF5A2 and Psne IF5A4 were transcribed in poplar flowers, stem, leaves, and roots. In addition, they were also induced by abiotic stresses. Transgenic yeast expressing Psne IF5A2 and Psne IF5A4 had increased salt, heavy metal, osmotic, oxidative tolerance. Our results suggest that Psne IF5A2 and Psne IF5A4 are excellent candidates for genetic engineering to improve salt and heavy metal tolerance in agricultural plants.Tangchun Zheng Lina Zang Lijuan Dai Chuanping Yang Guanzheng Qu 2017Journal of Forestry Research2017,28,3:4
5Research advances in and prospects of ornamental plant genomics显示文摘The term‘ornamental plant’refers to all plants with ornamental value,which generally have beautiful flowers or special plant architectures.China is rich in ornamental plant resources and known as the“mother of gardens”.Genomics is the science of studying genomes and is useful for carrying out research on genome evolution,genomic variations,gene regulation,and important biological mechanisms based on detailed genome sequence information.Due to the diversity of ornamental plants and high sequencing costs,the progress of genome research on ornamental plants has been slow for a long time.With the emergence of new sequencing technologies and a reduction in costs since the whole-genome sequencing of the first ornamental plant(Prunus mume)was completed in 2012,whole-genome sequencing of more than 69 ornamental plants has been completed in<10 years.In this review,whole-genome sequencing and resequencing of ornamental plants will be discussed.We provide analysis with regard to basic data from whole-genome studies of important ornamental plants,the regulation of important ornamental traits,and application prospects.Tangchun Zheng Ping Li Lulu Li Qixiang Zhang 2021Horticulture Research2021,8,1:2
6Genome-wide investigation of the bZIP transcription factor gene family in Prunus mume:Classification, evolution, expression profile and low-temperature stress responses显示文摘Prunus mume is an important woody plant that has high ornamental and economic value, widely distributed and used in landscape architecture in East Asia. In plants, basic(region) leucine zipper(bZIP) transcription factors play important regulatory roles in growth, development,dormancy and abiotic stress. To date, bZIP transcription factors have not been systematically studied in P. mume. In this study, 49 bZIP genes were first identified in P. mume, and the PmbZIP family was divided into 12 groups according to the grouping principles for the Arabidopsis thaliana bZIP family. For the first time, we constructed a detailed model of the PmbZIP domains(R-x_(3)–N-(x)_7-R/K-x_(2)-K-x_(6)-L-x_(6)-L-_(6)-L). Phylogenetic and synteny analyses showed that PmbZIPs duplication events might have occurred during the large-scale genome duplication events. A relatively short time of speciation and the finding that 91.84% of the bZIP genes formed orthologous pairs between P. mume and Prunus armeniaca provided evidence of a close relationship. Gene expression patterns were analysed in different tissues and periods, indicating that PmbZIP genes with the same motifs exhibited similar expression patterns. The gene expression results showed that PmbZIP31/36/41 genes played a more prominent role in the response to freezing stress than cold stress. The expression level of almost all subset Ⅲ genes was upregulated under freezing treatment, especially after cold exposure. We analysed the gene expression patterns of PmbZIP12/31/36/41/48 and their responses to low-temperature stress, which provided useful resources for future studies on the cold/freezing-tolerant molecular breeding of P. mume.Ping Li Tangchun Zheng Lulu Li Jia Wang Tangren Cheng Qixiang Zhang 2022Horticultural Plant Journal2022,8,2:2
7Comparison of dimension reduction-based logistic regression models for case-control genome-wide association study:principal components analysis vs.partial least squares显示文摘With recent advances in biotechnology, genome-wide association study(GWAS) has been widely used to identify genetic variants that underlie human complex diseases and traits. In case-control GWAS, typical statistical strategy is traditional logistical regression(LR) based on single-locus analysis. However, such a single-locus analysis leads to the well-known multiplicity problem, with a risk of inflating type I error and reducing power. Dimension reduction-based techniques, such as principal component-based logistic regression(PC-LR), partial least squares-based logistic regression(PLS-LR), have recently gained much attention in the analysis of high dimensional genomic data. However, the perfor?mance of these methods is still not clear, especially in GWAS. We conducted simulations and real data application to compare the type I error and power of PC-LR, PLS-LR and LR applicable to GWAS within a defined single nucleotide polymorphism(SNP) set region. We found that PC-LR and PLS can reasonably control type I error under null hypothesis.On contrast, LR, which is corrected by Bonferroni method, was more conserved in all simulation settings. In particular, we found that PC-LR and PLS-LR had comparable power and they both outperformed LR, especially when the causal SNP was in high linkage disequilibrium with genotyped ones and with a small effective size in simulation. Based on SNP set analysis, we applied all three methods to analyze non-small cell lung cancer GWAS data.Honggang Yi Hongmei Wo Yang Zhao Ruyang Zhang Junchen Dai Guangfu Jin Hongxia Ma Tangchun Wu Zhibin Hu Dongxin Lin Hongbing Shen Feng Chen 2015The Journal of Biomedical Research2015,29,4:2
8Dynamics of the SARS-CoV-2 antibody response up to 10 months after infection显示文摘COVID-19 caused by SARS-CoV-2 infection has caused substantial morbidity and mortality worldwide and paralyzed the international economy.Understanding the magnitude and duration of the antibody response to SARS-CoV-2 is important to achieve a balance between curbing the pandemic and minimizing adverse effects on society.1 Although the antibody response to SARS-CoV-2 within 9 months has been extensively studied,2,3,4,5,6 little is known about the magnitude and kinetics of antibody responses for over 9 months.Moreover,with limited observations over 9 months(n<100),2,7,8 several studies have produced inconsistent conclusions about antibody dynamics,suggesting different rates of antiviral antibody positivity at the last follow-up.2,7,8 These studies have been limited by a lack of measurement of neutralizing antibodies(NAbs),7 of inclusion of mild or asymptomatic cases,2,8 and of further exploration of potential predisposing factors for antibody dynamics.2,7 Considering the individual heterogeneity(such as disease severity)8 and time-dependent nature1 of the immune response,in-depth characterization of SARS-CoV-2 antibody kinetics across disease severity groups over a long period is urgently needed.Therefore,we repeatedly tested IgM,IgG,viral spike protein receptor-binding dom(anti-RBD)IgG,and NAb titers in COVID-19 patients during a follow-up period of up to 10 months and explored potential predisposing factors of antibody titers during follow-up.Hao Wang Yu Yuan Mingzhong Xiao Li Chen Youyun Zhao Haiwei Zhang Pinpin Long Yana Zhou Xi Xu Yanshou Lei Bihao Wu Tingyue Diao Hao Cai Li Liu Zuoyu Shao Jingzhi Wang Yansen Bai Kai Wang Miao Peng Linlin Liu Shi Han Fanghua Mei Kun Cai Yake Lei An Pan Chaolong Wang Rui Gong Xiaodong Li Tangchun Wu 2021Cellular & Molecular Immunology2021,18,7:1
9Genome assembly and resequencing analyses provide new insights into the evolution, domestication and ornamental traits of crape myrtle显示文摘Crape myrtle(Lagerstroemia indica)is a globally used ornamental woody plant and is the representative species of Lagerstroemia.However,studies on the evolution and genomic breeding of L.indica have been hindered by the lack of a reference genome.Here we assembled the first high-quality genome of L.indica using PacBio combined with Hi-C scaffolding to anchor the 329.14-Mb genome assembly into 24 pseudochromosomes.We detected a previously undescribed independent whole-genome triplication event occurring 35.5 million years ago in L.indica following its divergence from Punica granatum.After resequencing 73 accessions of Lagerstroemia,the main parents of modern crape myrtle cultivars were found to be L.indica and L.fauriei.During the process of domestication,genetic diversity tended to decrease in many plants,but this was not observed in L.indica.We constructed a high-density genetic linkage map with an average map distance of 0.33 cM.Furthermore,we integrated the results of quantitative trait locus(QTL)using genetic mapping and bulk segregant analysis(BSA),revealing that the major-effect interval controlling internode length(IL)is located on chr1,which contains CDL15,CRG98,and GID1b1 associated with the phytohormone pathways.Analysis of gene expression of the red,purple,and white flower-colour flavonoid pathways revealed that differential expression of multiple genes determined the flower colour of L.indica,with white flowers having the lowest gene expression.In addition,BSA of purple-and green-leaved individuals of populations of L.indica was performed,and the leaf colour loci were mapped to chr12 and chr17.Within these intervals,we identified MYB35,NCED,and KAS1.Our genome assembly provided a foundation for investigating the evolution,population structure,and differentiation of Myrtaceae species and accelerating the molecular breeding of L.indica.Yang Zhou Tangchun Zheng Ming Cai Lu Feng Xiufeng Chi Ping Shen Xin Wang Zhiting Wan Cunquan Yuan Man Zhang Yu Han Jia Wang Huitang Pan Tangren Cheng Qixiang Zhang 2023Horticulture Research2023,10,9:1

12Persistence of humoral and cellular immune response after SARS-CoV-2 infection: opportunities and challenges显示文摘The emerging COVID-19 pandemic caused by SARSCoV-2 infection has created a global crisis.Under the circumference of no effective treatment or vaccine,the Chinese government has implemented multifaceted measures of social distancing,home isolation,and centralized quarantine,which achieved a remarkable result of controlling the COVID-19 outbreak[1].However,the personal,psychological,economic,and societal consequences of the shutdown and physical distancing make it difficult to sustain these public health interventions for a long time[2].To find a new balance between curbing the pandemic and minimizing the indirect effects on society,a better understanding of adaptive immunity in response to SARS-CoV-2 infection is required.Tangchun Wu 2020Frontiers of Medicine2020,14,6:1

15Alternations in the gut microbiota and metabolome with newly diagnosed unstable angina显示文摘Gut microbiota plays an important role in coronary heart disease, but its compositional and functional changes in unstable angina(UA) remain unexplored. We performed metagenomic sequencing of 133 newly diagnosed UA patients and 133 sex-and age-matched controls, and profiled the fecal and plasma metabolomes in 30 case-control pairs. The alpha diversity of gut microbiota was increased in UA patients:the adjusted odds ratios(ORs) per standard deviation increase in Shannon and Simpson indices were 1.30(95% confidence interval, 1.01-1.70) and 1.36(1.05-1.81), respectively. Two common species(depleted Klebsiella pneumoniae and enriched Streptococcus parasanguinis;P ≤ 0.002) and three rare species(depleted Weissella confusa, enriched Granulicatella adiacens and Erysipelotrichaceae bacterium 6_1_45;P ≤ 0.005) were associated with UA. The UA-associated gut microbiota was depleted in the pathway of Lphenylalanine degradation(P = 0.001), primarily contributed by Klebsiella pneumoniae. Consistently, we found increased circulating phenylalanine in UA patients(OR = 2.76 [1.17-8.16]). Moreover, Streptococcus parasanguinis was negatively correlated with fecal citrulline(Spearman's r_(s)=-0.470, P = 0.009), a metabolite depleted in UA patients(OR = 0.26 [0.08-0.63]). These findings are informative to help understand the metabolic connection between gut microbiota and UA.Xuezhen Liu Miaoyan Shen Han Yan Pinpin Long Haijing Jiang Yizhi Zhang Lue Zhou Kuai Yu Gaokun Qiu Handong Yang Xiulou Li Xinwen Min Meian He Xiaomin Zhang Hyungwon Choi Chaolong Wang Tangchun Wu 2022Journal of Genetics and Genomics2022,49,3:1

18Effectiveness of inactivated COVID-19 vaccine against the severity of Omicron variant显示文摘The COVID-19 pandemic has led to unprecedented levels of morbidity,mortality,and economic disruption worldwide.Several non-pharmaceutical interventions have been implemented worldwide to curb the spread of SARS-CoV-2,including social distancing,home isolation,and centralized quarantine[1].Nevertheless,these interventions cannot be sustained over the longterm.Current hopes of controlling the pandemic rely heavily on vaccination,which remains the best tool available for preventing infection and symptomatic illness.Hao Wang Li Liu Tangchun Wu 2023Frontiers of Medicine2023,17,3:0
19Neutralization against SARS-CoV-2 Delta/Omicron variants and B cell response after inactivated vaccination among COVID-19 convalescents显示文摘Emerging SARS-CoV-2 variants have made COVID-19 convalescents susceptible to re-infection and have raised concern about the efficacy of inactivated vaccination in neutralization against emerging variants and antigen-specific B cell response.To this end,a study on a long-term cohort of 208 participants who have recovered from COVID-19 was conducted,and the participants were followed up at 3.3(Visit 1),9.2(Visit 2),and 18.5(Visit 3)months after SARS-CoV-2 infection.They were classified into three groups(no-vaccination(n=54),one-dose(n=62),and two-dose(n=92)groups)on the basis of the administration of inactivated vaccination.The neutralizing antibody(NAb)titers against the wild-type virus continued to decrease in the no-vaccination group,but they rose significantly in the one-dose and two-dose groups,with the highest NAb titers being observed in the two-dose group at Visit 3.The NAb titers against the Delta variant for the no-vaccination,one-dose,and two-dose groups decreased by 3.3,1.9,and 2.3 folds relative to the wild-type virus,respectively,and those against the Omicron variant decreased by 7.0,4.0,and 3.8 folds,respectively.Similarly,the responses of SARS-CoV-2 RBD-specific B cells and memory B cells were boosted by the second vaccine dose.Results showed that the convalescents benefited from the administration of the inactivated vaccine(one or two doses),which enhanced neutralization against highly mutated SARS-CoV-2 variants and memory B cell responses.Two doses of inactivated vaccine among COVID-19 convalescents are therefore recommended for the prevention of the COVID-19 pandemic,and vaccination guidelines and policies need to be updated.Hao Wang Yu Yuan Bihao Wu Mingzhong Xiao Zhen Wang Tingyue Diao Rui Zeng Li Chen Yanshou Lei Pinpin Long Yi Guo Xuefeng Lai Yuying Wen Wenhui Li Hao Cai Lulu Song Wei Ni Youyun Zhao Kani Ouyang Jingzhi Wang Qi Wang Li Liu Chaolong Wang An Pan Xiaodong Li Rui Gong Tangchun Wu 2023Frontiers of Medicine2023,17,4:0
20The role of natriuretic peptide precursor A gene polymorphism in the development of coronary heart disease in Chinese Han population显示文摘Natriuretic peptide precursor A(NPPA)is synthesized,stored,and released by atrial myocytes.Previous studies have shown that NPPA plays a significant role in the regulation of coronary circulation and in atherosclerosis.Rs5065 NPPA gene polymorphism leads to the translation of NPPA with two additional arginines and has been suggested to be associated with salt-sensitive hypertension.The purpose of the present study was to investigate the relationship between the rs5065 NPPA gene polymorphism and the risk of coronary heart disease(CHD)in Chinese Han population.We genotyped the single nucleotide polymorphism(SNP)rs5065 NPPA in the human NPPA gene in 1861 sex-and age-matched subjects,comprising of 904 CHD cases and 957 controls of Chinese Han population.Genotyping of SNP was performed with Taqman SNP allelic discrimination assays by means of an ABI 7900HT.Our study showed that the frequencies of rs5065 NPPA C allele in the case and the control groups were 0.012 and 0.005,respectively.There was significant difference in C allele frequency distribution between the two groups(OR=2.607,95%CI:1.197–5.678,P=0.012).In the case group,there was significant difference between smokers and nonsmokers with subjects carrying C allele(P=0.037),and no significant difference in gender,age,fasting total cholesterol(TC),triglycerides(TG),fasting plasma glucose(FPG),body mass index(BMI),and blood pressure(BP)between the cases and the controls(P>0.05).Our results suggest that the C allele of rs5065 NPPA gene polymorphism may be associated with the risk of CHD.Ripen NSENGA Longxian CHENG Mei’an HE Tangchun WU 2009Frontiers of Medicine2009,3,4:0
