| 1 | Identification and genetic mapping of four novel genes that regulate leaf development in Arabidopsis显示文摘Molecular and genetic characterizations of mutants have led to a better understanding of many developmental processes in the model system Arabidopsis thaliana. However, the leaf development that is specific to plants has been little studied. With the aim of contributing to the genetic dissection of leaf development, we have performed a large-scare screening for mutants with abnormal leaves. Among a great number of leaf mutants we have generated by T-DNA and transposon tagging and ethylmethae sulfonate (EMS) mutagenesis, four independent mutant lines have been identified and studied genetically. Phenotypes of these mutant lines represent the defects of four novel nuclear genes designated LL1 (LOTUS LEAF 1), LL2 (LOTUS LEAF 2), URO (UPRIGHT ROSETTE), and EIL (ENVIRONT CONDITION INDUCED LESION). The phenotypic analysis indicates that these genes play important roles during leaf development. FOr the further genetic analysis of these genes and the map-based cloning of LL1 and LL2, we have mapped these genes to chromosome regions with an efficient and rapid mapping method. | SUN YUE WEI ZHANG FENG LING LI YING LI GUO TIAN LEI LIU HAI HUANG | 2000 | Cell Research2000,10,4: | 53 |

| 4 | Effectiveness of Different Waist Circumference Cut-off Values in Predicting Metabolic Syndrome Prevalence and Risk Factors in Adults in China显示文摘Objective To study the effectiveness of waist circumference cut-off values in predicting the prevalence of metabolic syndrome(MetS) and risk factors in adults in China. Methods A cross-sectional survey was condcuted in 14 provinces(autonomous region, municipality) in China. A total of 47 325 adults aged ≥20 years were selected by multistage stratified sampling, and questionnaire survey and physical and clinical examination were conducted among them. MetS was defined according to the International Diabetes Federation(IDF) criteria and modified IDF criteria.Results The age-standardized prevalence of MetS was 24.2%(22.1% in men and 25.8% in women) and 19.5%(22.1% in men and 18.0% in women) according to the IDF criteria and modified IDF criteria respectively. The age-standardized prevalence of pre-MetS was 8.1%(8.6% in men and 7.8% in women) according to the modified IDF criteria. The prevalence of MetS was higher in urban residents than rural residents and in northern China residents than in southern China residents. The prevalence of central obesity was about 30% in both men and women according to the ethnicity-specific cut-off values of waist circumference for central obesity(90 cm for men and 85 cm for women). Multivariate regression analysis revealed no significant difference in risk factors between the two MetS definitions. Conclusion Using both the modified IDF criteria and ethnicity-specific cut-off values of waist circumference can provide more useful information about the prevalence of MetS in China. | ZHOU Hai Cheng LAI Ya Xin SHAN Zhong Yan JIA Wei Ping YANG Wen Ying LU Ju Ming WENG Jian Ping JI Li Nong LIU Jie TIAN Hao Ming JI Qiu He ZHU Da Long CHEN Li GUO Xiao Hui ZHAO Zhi Gang Li Qiang ZHOU Zhi Guang GE Jia Pu SHAN Guang Liang | 2014 | Biomedical and Environmental Sciences2014,27,5: | 17 |

| 6 | Evaluating the Nutritional Status of Oncology Patients and Its Association with Quality of Life显示文摘Objective The primary aim of the study was to compare two nutritional status evaluation tools: the Patient-Generated Subjective Global Assessment(PG-SGA) and Nutritional Risk Screening(NRS-2002). Using the European Organization for Research and Treatment of Cancer Quality of Life Core Questionnaire 30(EORTC QLQ-C30), the second aim was to provide constructive advice regarding the quality of life of patients with malignancy. Methods This study enrolled 312 oncology patients and assessed their nutritional status and quality of life using the PG-SGA, NRS-2002, and EORTC QLQ-C30. Results The data indicate that 6% of the cancer patients were well nourished. The SGA-A had a higher sensitivity(93.73%) but a poorer specificity(2.30%) than the NRS-2002(69.30% and 25.00%, respectively) after comparison with albumin. There was a low negative correlation and a high similarity between the PG-SGA and NRS-2002 for evaluating nutritional status, and there was a significant difference in the median PG-SGA scores for each of the SGA classifications(P < 0.001). The SGA-C group showed the highest PG-SGA scores and lowest body mass index. The majority of the target population received 2 points for each item in our 11-item questionnaire from the EORTC QLQ-C30. Conclusion The data indicate that the PG-SGA is more useful and suitable for evaluating nutritional status than the NRS-2002. Additionally, early nutrition monitoring can prevent malnutrition and improve the quality of life of cancer patients. | ZHANG Ya Hui XIE Fang Yi CHEN Ya Wen WANG Hai Xia TIAN Wen Xia SUN Wen Guang WU Jing | 2018 | Biomedical and Environmental Sciences2018,31,9: | 14 |

| 8 | SbHKT1;4, a member of the high‐affinity potassium transporter gene family from Sorghum bicolor, functions to maintain optimal Na^+/K^+ balance under Na^+ stress显示文摘In halophytic plants, the high‐affinity potassium transporter HKT gene family can selectively uptake Kt in the presence of toxic concentrations of Nat. This has so far not been well examined in glycophytic crops. Here, we report the characterization of SbHKT1;4, a member of the HKT gene family from Sorghum bicolor. Upon Nat stress, SbHKT1;4 expression was more strongly upregulated in salt‐tolerant sorghum accession, correlating with a better balanced Nat/ Kt ratio and enhanced plant growth. Heterogeneous expression analyses in mutants of Saccharomyces cerevisiae and Arabidopsis thaliana indicated that overexpressing SbHKT1;4 resulted in hypersensitivity to Nat stress, and such hypersensitivity could be alleviated with the supply of elevated levels of Kt, implicating that SbHKT1;4 may mediate Kt uptake in the presence of excessive Nat. Further electrophysiological evidence demonstrated that SbHKT1;4 could transport Nat and Kt when expressed in Xenopus laevis oocytes. The relevance of the finding that SbHKT1;4 functions to maintain optimal Nat/Kt balance under Nat stress to the breeding of salt‐tolerant glycophytic crops is discussed. | Tian‐Tian Wang Zhi‐Jie Ren Zhi‐Quan Liu Xue Feng Rui‐Qi Guo Bao‐Guo Li Le‐Gong Li Hai‐Chun Jing | 2014 | Journal of Integrative Plant Biology2014,56,3: | 11 |
| 9 | Mycoplasma pneumoniae Macrolide Resistance and MLVA Typing in Children in Beijing,China,in 2016:Is It Relevant?显示文摘Objective The aim of this study is to investigate the macrolide resistance rate and molecular type with multiple-locus variable-number tandem-repeat analysis(MLVA)of Mycoplasma pneumoniae of Beijing in 2016 in pediatric patients.Methods Real-time quantitative polymerase chain reaction(PCR)was used to identify M.pneumoniae,and MLVA was performed.The domain V of the 23 S rRNA was sequenced to detect macrolide-resistant point mutations.We also investigated the activities of antibiotics against M.pneumoniae isolates in vitro.Results The PCR detection rate of M.pneumoniae in children in Beijing was 40%,and the macrolide resistance rate was 66%.The A2063 G mutation in the 23 S rRNA V region is the dominant mutation(137/146,93.84%),whereas the A2064 G mutation is rare(9/146,6.16%).Seventy-three samples were typed successfully by MLVA typing,including 86.3%(63/73)were MLVA type 4-5-7-2,and 13.7%(10/73)were MLVA type 3-5-6-2.No other types were found.No strains were resistant to levofloxacin or tetracycline.Conclusion In 2016,a specific decrease in the macrolide resistance rate occurred in Beijing.The detection rate and macrolide resistance rate of outpatients are lower than those of inpatients.The A2063 G mutants M.pneumoniae have high levels of resistance to erythromycin and azithromycin.The primary MLVA type is 4-5-7-2,followed by 3-5-6-2.No other MLVA types were detected.No strains resistant to tetracycline or levofloxacin were found in vitro. | DOU Hai Wei TIAN Xiu Jun XIN De Li WEI Ran ZHOU Wei WANG Hong QIN Xuan Guang SHAO Jun Yan XU Bao Ping GE Li Xia SHI Da Wei | 2020 | Biomedical and Environmental Sciences2020,33,12: | 9 |

| 11 | Correlation of Seven Biological Factors(Hsp90α,p53,MDM2,Bcl-2,Bax,Cytochrome C,and Cleaved caspase3)with Clinical Outcomes of ALK+ Anaplastic Large-cell Lymphoma显示文摘Objective To explore correlation of seven apoptosis‐related proteins (Hsp90α,p53,MDM2,Bcl‐2,Bax,Cytochrome C,and Cleaved caspase3) with clinical outcomes of ALK+ anaplastic large‐cell lymphoma (ALCL).Methods Using immunohistochemistry and immunofluorescence double staining methods,the expressions of these seven apoptosis‐associated proteins were studied to clarify their relationship with clinical outcomes of 36 ALK+ and 25 ALK‐ systemic ALCL patients enrolled between 1996 and 2006.The relationship of these apoptosis‐regulating proteins with NPM‐ALK status was also evaluated with the tyrosine inhibitor herbimycin A (HA) in vitro by immunocytochemistry,Western blotting and flow cytometric assays.Results The presence of Hsp90α‐,MDM2‐,Bax‐,Cytochrome C,and Cleaved caspase3‐positive tumor cells was found significantly different in ALK+ and ALK‐ ALCLs ,which was correlated with highly favorable clinical outcome.The Bcl‐2‐ and p53‐positive tumor cells were found in groups of patients with unfavorable prognosis.Inhibition of NPM‐ALK by HA could reactivate the p53 protein and subsequent apoptosis‐related proteins and therefore induced apoptosis in ALK+ ALCL cells.Conclusion Our results suggest that these seven proteins might be involved in apoptosis regulation and associated with clinical outcome of ALK+ systemic ALCLs.We also reveal a dynamic chain relation that NPM‐ALK regulates p53 expression and subsequent apoptosis cascade in ALK+ ALCLs. | LI Hui Ling HUANG Xue Ping ZHOU Xin Hua JI Tian Hai WU Zi Qing WANG Zhi Qiang JIANG Hui Yong LIU Fan Rong ZHAO Tong | 2011 | Biomedical and Environmental Sciences2011,24,6: | 9 |
| 12 | Simultaneous Detection of 13 Key Bacterial Respiratory Pathogens by Combination of Multiplex PCR and Capillary Electrophoresis显示文摘Objective Lower respiratory tract infections continue to pose a significant threat to human health. It is important to accurately and rapidly detect respiratory bacteria. To compensate for the limits of current respiratory bacteria detection methods, we developed a combination of multiplex polymerase chain reaction(PCR) and capillary electrophoresis(MPCE) assay to detect thirteen bacterial pathogens responsible for lower respiratory tract infections, including Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis, Pseudomonas aeruginosa, Klebsiella pneumoniae, Escherichia coli, Staphylococcus aureus, Mycoplasma pneumoniae, Legionella spp., Bordetella pertussis, Mycobacterium tuberculosis complex, Corynebacterium diphtheriae, and Streptococcus pyogenes. Methods Three multiplex PCR reactions were built, and the products were analyzed by capillary electrophoresis using the high-throughput DNA analyzer. The specificity of the MPCE assay was examined and the detection limit was evaluated using DNA samples from each bacterial strain and the simulative samples of each strain. This assay was further evaluated using 152 clinical specimens and compared with real-time PCR reactions. For this assay, three nested-multiplex-PCRs were used to detect these clinical specimens. Results The detection limits of the MPCE assay for the 13 pathogens were very low and ranged from 10^(-7) to 10^(-2) ng/μL. Furthermore, analysis of the 152 clinical specimens yielded a specificity ranging from 96.5%-100.0%, and a sensitivity of 100.0% for the 13 pathogens. Conclusion This study revealed that the MPCE assay is a rapid, reliable, and high-throughput method with high specificity and sensitivity. This assay has great potential in the molecular epidemiological survey of respiratory pathogens. | JIANG Lu Xi REN Hong Yu ZHOU Hai Jian ZHAO Si Hong HOU Bo Yan YAN Jian Ping QIN Tian CHEN Yu | 2017 | Biomedical and Environmental Sciences2017,30,8: | 8 |
| 13 | Progress in the mechanism and targeted drug therapy for COPD显示文摘Chronic obstructive pulmonary disease(COPD)is emphysema and/or chronic bronchitis characterised by long-term breathing problems and poor airflow.The prevalence of COPD has increased over the last decade and the drugs most commonly used to treat it,such as glucocorticoids and bronchodilators,have significant therapeutic effects;however,they also cause side effects,including infection and immunosuppression.Here we reviewed the pathogenesis and progression of COPD and elaborated on the effects and mechanisms of newly developed molecular targeted COPD therapeutic drugs.Among these new drugs,we focussed on thioredoxin(Trx).Trx effectively prevents the progression of COPD by regulating redox status and protease/anti-protease balance,blocking the NF-κB and MAPK signalling pathways,suppressing the activation and migration of inflammatory cells and the production of cytokines,inhibiting the synthesis and the activation of adhesion factors and growth factors,and controlling the cAMP-PKA and PI3K/Akt signalling pathways.The mechanism by which Trx affects COPD is different from glucocorticoid-based mechanisms which regulate the inflammatory reaction in association with suppressing immune responses.In addition,Trx also improves the insensitivity of COPD to steroids by inhibiting the production and internalisation of macrophage migration inhibitory factor(MIF).Taken together,these findings suggest that Trx may be the ideal drug for treating COPD. | Cuixue Wang Jiedong Zhou Jinquan Wang Shujing Li Atsushi Fukunaga Junji Yodoi Hai Tian | 2020 | Signal Transduction and Targeted Therapy2020,5,1: | 8 |

| 15 | Coxsackievirus B3 Infection Triggers Autophagy through 3 Pathways of Endoplasmic Reticulum Stress显示文摘Objective Autophagy is a highly conserved intracellular degradation pathway. Many picornaviruses induce autophagy to benefit viral replication, but an understanding of how autophagy occurs remains incomplete. In this study, we explored whether coxsackievirus B3(CVB3) infection induced autophagy through endoplasmic reticulum(ER) stress. Methods In CVB3-infected HeLa cells, the specific molecules of ER stress and autophagy were detected using Western blotting, reverse transcription polymerase chain reaction(RT-PCR), and confocal microscopy. Then PKR-like ER protein kinase(PERK) inhibitor, inositol-requiring protein-1(IRE1) inhibitor, or activating transcription factor-6(ATF6) inhibitor worked on CVB3-infected cells, their effect on autophagy was assessed by Western blotting for detecting microtubule-associated protein light chain 3(LC3). Results CVB3 infection induced ER stress, and ER stress sensors PERK/eIF2α, IRE1/XBP1, and ATF6 were activated. CVB3 infection increased the accumulation of green fluorescent protein(GFP)-LC3 punctuation and induced the conversion from LC3-Ⅰ to phosphatidylethanolamine-conjugated LC3-1(LC3-Ⅱ). CVB3 infection still decreased the expression of mammalian target of rapamycin(mTOR) and p-mTOR. Inhibition of PERK, IRE1, or ATF6 significantly decreased the ratio of LC3-Ⅱ to LC3-Ⅰ in CVB3-infected HeLa cells. Conclusion CVB3 infection induced autophagy through ER stress in HeL a cells, and PERK, IRE1, and ATF6 a pathways participated in the regulation of autophagy. Our data suggested that ER stress may inhibit mTOR signaling pathway to induce autophagy during CVB3 infection. | LUO Xiao Nuan YAO Hai Lan SONG Juan SONG Qin Qin SHI Bing Tian XIA Dong HAN Jun | 2018 | Biomedical and Environmental Sciences2018,31,12: | 8 |
| 16 | Association of Overlapped and Un-overlapped Comorbidities with COVID-19 Severity and Treatment Outcomes: A Retrospective Cohort Study from Nine Provinces in China显示文摘Objective Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear.Methods A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients’ medical records. Multivariable logistic regression models were used to estimate the odds ratio(OR) and 95% confidence interval(95% CI) of the associations between comorbidities(cardiometabolic or non-cardiometabolic diseases), clinical severity, and treatment outcomes of COVID-19.Results Overall, 158(13.6%) patients were diagnosed with severe illness and 32(2.7%) had unfavorable outcomes. Hypertension(2.87, 1.30–6.32), type 2 diabetes(T2 DM)(3.57, 2.32–5.49),cardiovascular disease(CVD)(3.78, 1.81–7.89), fatty liver disease(7.53, 1.96–28.96), hyperlipidemia(2.15, 1.26–3.67), other lung diseases(6.00, 3.01–11.96), and electrolyte imbalance(10.40, 3.00–26.10)were independently linked to increased odds of being severely ill. T2 DM(6.07, 2.89–12.75), CVD(8.47,6.03–11.89), and electrolyte imbalance(19.44, 11.47–32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission(5.46,3.25–9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes(6.58, 1.46–29.64) within two weeks.Conclusion Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes. | MA Yan ZHU Dong Shan CHEN Ren Bo SHI Nan Nan LIU Si Hong FAN Yi Pin WU Gui Hui YANG Pu Ye BAI Jiang Feng CHEN Hong CHEN Li Ying FENG Qiao GUO Tuan Mao HOU Yong HU Gui Fen HU Xiao Mei HU Yun Hong HUANG Jin HUANG Qiu Hua HUANG Shao Zhen JI Liang JIN Hai Hao LEI Xiao LI Chun Yan LI Min Qing LI Qun Tang LI Xian Yong LIU Hong De LIU Jin Ping LIU Zhang MA Yu Ting MAO Ya MO Liu Fen NA Hui WANG Jing Wei SONG Fang Li SUN Sheng WANG Dong Ting WANG Ming Xuan WANG Xiao Yan WANG Yin Zhen WANG Yu Dong WU Wei WU Lan Ping XIAO Yan Hua XIE Hai Jun XU Hong Ming XU Shou Fang XUE Rui Xia YANG Chun YANG Kai Jun YUAN Sheng Li ZHANG Gong Qi ZHANG Jin Bo ZHANG Lin Song ZHAO Shu Sen ZHAO Wan Ying ZHENG Kai ZHOU Ying Chun ZHU Jun Teng ZHU Tian Qing ZHANG Hua Min WANG Yan Ping WANG Yong Yan 无 | 2020 | Biomedical and Environmental Sciences2020,33,12: | 8 |
| 17 | The absolute paleoposition of the North China Block during the Middle Ordovician显示文摘Present-day hot spots and Phanerozoic large igneous provinces(LIPs) and kimberlites mainly occur at the edges of the projections of Large Low Shear Wave Velocity Provinces(LLSVPs) on the earth's surface. If a plate contains accurately dated LIPs or kimberlites, it is possible to obtain the absolute paleoposition of the plate from the LIP/kimberlite and paleomagnetic data. The presence of Middle Ordovician kimberlites in the North China Block provides an opportunity to determine the absolute paleoposition of the block during the Middle Ordovician. In addition to paleobiogeographical information and the results of previous work on global plate reconstruction for the Ordovician Period, we selected published paleomagnetic data for the North China Block during the Middle Ordovician and determined the most reasonable absolute paleoposition of the North China Block during the Middle Ordovician: paleolatitude of approximately 16.6°S to 19.1°S and paleolongitude of approximately 10°W. The block was located between the Siberian Plate and Gondwana, close to the Siberian Plate. During the Cambrian and Ordovician periods, the North China Block may have moved toward the Siberian Plate and away from the Australian Plate. | WANG Hong Hao LI Jiang Hai ZHANG Hua Tian XU Li LI Wei Bo | 2016 | Science China Earth Sciences2016,59,3: | 6 |
| 18 | Orbital-scale Asian summer monsoon variations:Paradox and exploration显示文摘The Asian summer monsoon(ASM) is a vast climate system, whose variability is critical to the livelihoods of billions of people across the Asian continent. During the past half-century, much progress has been made in understanding variations on a wide range of timescales, yet several significant issues remain unresolved. Of note are two long-standing problems concerning orbital-scale variations of the ASM.(1) Chinese loess magnetic susceptibility records show a persistent glacial-interglacial dominated ~100 kyr(thousand years) periodicity, while the cave oxygen-isotope(δ18 O) records reveal periodicity in an almost pure precession band(~20 kyr periodicity)—the 'Chinese 100 kyr problem'.(2) ASM records from the Arabian Sea and other oceans surrounding the Asian continent show a significant lag of 8–10 kyr to Northern Hemisphere summer insolation(NHSI), whereas the Asian cave δ18 O records follow NHSI without a significant lag—a discrepancy termed the 'sea-land precession-phase paradox'. How can we reconcile these differences? Recent and more refined model simulations now provide spatial patterns of rainfall and wind across the precession cycle, revealing distinct regional divergences in the ASM domain, which can well explain a large portion of the disparities between the loess, marine, and cave proxy records. Overall, we also find that the loess, marine, and cave records are indeed complementary rather than incompatible, with each record preferentially describing a certain aspect of ASM dynamics. Our study provides new insight into the understanding of different hydroclimatic proxies and largely reconciles the 'Chinese 100 kyr problem' and 'sea-land precession-phase paradox'. | Hai CHENG Haiwei ZHANG Yanjun CAI Zhengguo SHI Liang YI Chenglong DENG Qingzhen HAO Youbing PENG Ashish SINHA Hanying LI Jingyao ZHAO Ye TIAN Jonathan BAKER Carlos PEREZ-MEJIAS | 2021 | Science China Earth Sciences2021,64,4: | 6 |
| 19 | Multi-locus variable-number tandem repeat analysis of Chinese Brucella strains isolated from 1953 to 2013显示文摘Background:Brucellosis was a common human and livestock disease caused by Brucella strains,the category B priority pathogens by the US Center for Disease Control(CDC).Identified as a priority disease in human and livestock populations,the increasing incidence in recent years in China needs urgent control measures for this disease but the molecular background important for monitoring the epidemiology of Brucella strains at the national level is still lacking.Methods:A total of 600 Brucella isolates collected during 60 years(from 1953 to 2013)in China were genotyped by multiple locus variable-number tandem repeat analysis(MLVA)and the variation degree of MLVA11 loci was calculated by the Hunter Gaston Diversity Index(HGDI)values.The charts and map were processed by Excel 2013,and cluster analysis and epidemiological distribution was performed using BioNumerics(version 5.1).Results:The 600 representative Brucella isolates fell into 104 genotypes with 58 singleton genotypes by the MLVA11 assay,including B.melitensis biovars 2 and 3(five main genotypes),B.abortus biovars 1 and 3(two main genotypes),B.suis biovars 1 and 3(three main genotypes),and B.canis(two main genotypes)respectively.While most B.suis biovar 1 and biovar 3 were respectively found in northern provinces and southern provinces,B.melitensis and B.abortus strains were dominant in China.Canine Brucellosis was only found in animals without any human cases reported.Eight Brucellosis epidemic peaks emerged during the 60 years between 1953 and 2013:1955-1959,1962-1969,1971-1975,1977-1983,1985-1989,1992-1997,2000-2008 and 2010-2013 in China.Conclusions:Brucellosis has its unique molecular epidemiological patterns with specific spatial and temporal distribution according to MLVA.Trial registration:IDOP-D-16-00101. | Guo-Zhong Tian Bu-Yun Cui Dong-Ri Piao Hong-Yan Zhao Lan-Yu Li Xi Liu Pei Xiao Zhong-Zhi Zhao Li-Qing Xu Hai Jiang Zhen-Jun Li | 2017 | Infectious Diseases of Poverty2017,6,1: | 6 |
