1Th22 cells are associated with hepatocellular carcinoma development and progression显示文摘Objective: IL-22-producing CD4+ T helper cells(Th22 cells) have been identified as major inducers of tissue inflammation and immune responses. Currently, no previous study explored the role of Th22 cells in the pathogenesis of hepatocellular carcinoma(HCC). The study aimed to determine the biological function of Th22 cells and its effector IL-22 in HCC patients.Methods: Forty-five HCC patients and 19 healthy controls were recruited and their peripheral blood was collected. The fresh HCC tissues, adjacent HCC tissues and ten normal liver tissues were also collected. Flow cytometry analysis was used to determine the frequencies of circulating Th22 cells and Th17 cells. Serum IL-22 levels were tested by enzyme-linked immunosorbent assay(ELISA). Immunohistochemical staining and real-time polymerase chain reaction(PCR) were used to detect IL-22 protein and mRNA in tissues specimens, respectively.Results: Circulating Th22 cells, Th17 cells and serum IL-22 levels were significantly elevated in HCC patients compared with those of healthy controls(P<0.001). Th22 cells were showed to be positively correlated with IL-22 in HCC patients(P<0.05), but not in healthy controls. No significant differences were found in HCC patients with HBeAg positivity or negativity in term of Th22 cells and serum IL-22 levels. The expression of IL-22 protein and mRNA was highest in HCC tissues, followed by adjacent HCC tissues and normal liver tissues. Furthermore, Th22 cells, serum IL-22 levels and IL-22 mRNA were elevated at stage III-IV compared with stage I-II of HCC(P<0.05).Conclusions: Elevation of circulating Th22 cells and IL-22 may be implicated in the pathogenesis of HCC, and potentially be cellular targets for therapeutic intervention.Shanyu Qin Shijia Ma Xiaoli Huang Donghong Lu You Zhou Haixing Jiang 2014Chinese Journal of Cancer Research2014,26,2:25

3Treatment and outcomes of 1041 pediatric patients with neuroblastoma who received multidisciplinary care in China显示文摘Importance:Neuroblastoma is the most common extracranial malignant solid tumor in children.Multidisciplinary care is critical to improving the survival of pediatric patients with neuroblastoma.Objective:To systematically summarize the clinical characteristics of children with neuroblastoma and evaluate their prognosis with multidisciplinary care provided in a single center.Methods:This retrospective study analyzed the clinical data of 1041 patients with neuroblastoma who were diagnosed,treated,and followed-up in the Hematology-Oncology Center of Beijing Children’s Hospital from 2007 to 2019.Results:The median age at diagnosis was 34 months;80.8%of the patients were younger than 5 years of age.Notably,243 patients(23.3%)were classified as low-risk,249 patients(23.9%)were classified as intermediate-risk,and 549(52.7%)were classified as high-risk.Furthermore,956 patients underwent surgical resections;986(94.7%)patients received chemotherapy;and 176 patients with high-risk neuroblastoma received hematopoietic stem cell transplantation.The 5-year event-free survival(EFS)rate was 91.3%and 5-year overall survival(OS)rate was 97.5%in low-risk group;in the intermediate-risk group,these rates were 85.1%and 96.7%,respectively,while they were 37.7%and 48.9%in the high-risk group(P<0.001 for both).The 5-year EFS and OS rates were significantly higher in patients diagnosed between 2015 and 2019 than in patients diagnosed between 2007 and 2014(P<0.001).In total,278 patients(26.7%)exhibited tumor relapse or progression;the median interval until relapse or progression was 14 months.Of the 233 patients who died,83%died of relapse or progression of neuroblastoma and 4.3%died of therapy-related complications.Interpretation:The 5-year OS rate was low in high-risk patients,compared with low-and intermediate-risk patients.Multidisciplinary care is critical for improvement of survival in pediatric patients with neuroblastoma.Additional treatment strategies should be sought to improve the prognosis of patients with high-risk neuroblastoma.Yan Su Hong Qin Chenghao Chen Shengcai Wang Shihan Zhang Dawei Zhang Mei Jin Yun Peng Lejian He Xiaoman Wang Suyun Qian Maoquan Qin Ming Ge Fuquan Zhang Qi Zeng Huanmin Wang Xiaoli Ma Xin Ni 2020Pediatric Investigation2020,4,3:16
4Numerical simulation and experimental investigation of natural convection heat transfer of molten salt around fine wire显示文摘In order to get the natural convection heat transfer mechanism of molten salt, the experimental investigation of natural convective heat transfer of LiNO3was studied after it was simulated by numerical calculation. Experiment was carried out on the nat-ural convection heat transfer of air and water around the fine wire using the method of Joule heating. The results showed that the natural convection heat transfer of air and water around the fine wire agreed well with Fand's correlation. Based on the aforementioned experiment, the natural convection heat transfer of molten salt LiNO3was studied by experiment and the same results were got. Therefore, the natural convection heat transfer of molten salt can be calculated by Fand's correlation, which takes into consideration the effect of viscosity dissipation.LU YuanWei LI XiaoLi LI Qiang WU YuTing MA ChongFang 2013Science China(Technological Sciences)2013,56,7:13
5Therapeutic potential of intravenous Xuebijing on transforming growth factor β_1 and procollagen type III peptide in patients with acute paraquat poisoning显示文摘OBJECTIVE:Paraquat(PQ) poisoning-induced pulmonary fibrosis causes asphyxiation and death.The therapeutic potential of intravenous Xuebijing therapy in PQ poisoning patients and its underlying immunomodulatory effects on transforming growth factor(TGF)-β1 and procollagen type III peptide(PIIIP) were investigated.METHODS:Thirty-six acute PQ poisoning patients were randomly assigned to conventional therapy(Group A) and intravenous Xuebijing administration plus conventional therapy(Group B).Twenty volunteers served as controls(Group C).Blood samples were collected upon admission(day 0) and at post-treatment days 5,10,and 14.TGF-β1 and PIIIP concentrations were determined by ELISA and analyzed for intra-and inter-group differences over time.One-month follow-up was conducted for determining the mortality rate.RESULTS:TGF-β1 and PIIIP levels were significantly higher in PQ poisoning patients and increased over time(Groups A and B vs C,P<0.01).However,the TGF-β1 and PIIIP levels were consistently significantly lower in Group B compared with those of Group A(P<0.01).The 1-month mortality rate was also lower in Group B compared with that of Group A(P<0.05).PQ poisoning patients showed remarkably high levels of TGF-β1 and PIIIP,which increased as PQ-induced pulmonary fibrosis progressed.CONCLUSION:Treatment with intravenous Xuebijing plus conventional therapy significantly lowered TGF-β1 and PIIIP levels,which indicates therapeutic efficacy in the treatment of PQ poisoning patients.Xuebing Zheng Xiaoli Sun Piyong Ma Zhongming Liu Nan Jiang 2012Journal of Traditional Chinese Medicine2012,32,4:11

7Carbon Capture and Storage:History and the Road Ahead显示文摘The large-scale deployment of carbon capture and storage(CCS)is becoming increasingly urgent in the global path toward net zero emissions;however,global CCS deployment is significantly lagging behind its expected contribution to greenhouse gas emission reduction.Reviewing and learning from the examples and history of successful CCS practices in advanced countries will help other countries,including China,to promote and deploy CCS projects using scientific methods.This paper shows that the establishment of major science and technology CCS infrastructures in advanced countries has become the main source of CCS technological innovation,cost reduction,risk reduction,commercial promotion,and talent training in the development and demonstration of key CCS technologies.Sound development of CCS requires a transition from pilot-scale science and technology infrastructures to large-scale commercial infrastructures,in addition to incentive policies;otherwise,it will be difficult to overcome the technical barriers between small-scale demonstrations and the implementation of million-tonne-scale CCS and ten-million-tonne-scale CCS hubs.Geological CO_(2) storage is the ultimate goal of CCS projects and the driving force of CO_(2) capture.Further improving the accuracy of technologies for the measurement,monitoring,and verification(MMV)of CO_(2) storage capacity,emission reduction,and safety remains a problem for geological storage.CO_(2) storage in saline aquifers can better couple multiple carbon emission sources and is currently a priority direction for development.Reducing the energy consumption of lowconcentration CO_(2) capture and the depletion of chemical absorbents and improving the operational efficiency and stability of post-combustion CO_(2) capture systems have become the key constraints to largescale CCS deployment.Enhanced oil recovery(EOR)is also important in order for countries to maximize fossil fuel extraction instead of importing oil from less environmentally friendly oil-producing countries.Jinfeng Ma Lin Li Haofan Wang Yi Du Junjie Ma Xiaoli Zhang Zhenliang Wang 2022Engineering2022,8,7:9
8Housing characteristics and indoor environment in relation to children's asthma, allergic diseases and pneumonia in Urumqi, China显示文摘In order to evaluate the prevalence of childhood asthma,allergic diseases and pneumonia in Urumqi City,China,as well as its associations with housing and home characteristics,a cross-sectional study was performed in 4618 children(81.7%response rate,average age 4.7±0.9 year,boys accounting for 53.7%).Questions on children’s asthma and allergic diseases were from the International Study on Asthma and Allergies in Childhood(ISAAC)and were integrated with questions on the home environment from the Dampness in Buildings and Health(DBH)study,slightly modified to account for Chinese building characteristics and life habits.The prevalences of physician diagnosed asthma,allergic rhinitis(AR)and pneumonia were 3.6%,8.7%and 40.9%,respectively.One fourth of children reported wheezing and more than 40%AR symptoms in the last 12 months.Controlling for confounding factors,positive associations were found for home mold/dampness and wheezing(adjusted odds ratio,aOR 1.33,95%CI 1.07 1.66),AR symptoms(1.34,1.09 1.64)last 12 months and physician diagnosed pneumonia(1.33,1.09 1.62).Floor material by wood,PVC or carpeting;and walls by wallpaper,painting or wood material,were positively associated with AR symptoms.Home environmental tobacco smoke(ETS)was positively associated with wheezing(1.23,1.04 1.46)and pneumonia(1.25,1.07 1.45).In conclusion,there was a relatively high prevalence of asthmatic and AR symptoms and diagnosed pneumonia in preschool children in Urumqi.Home signs of mold growth or dampness,windowpane condensation,as well as ETS and interior surface materials emitting chemicals were risk factors for allergic symptoms and pneumonia.WANG TingTing ZHAO ZhuoHui YAO Hua WANG ShuLan NORBACK Dan CHEN Jie MA JinFeng JI XiaoLi WANG Li SUNDELL Jan 2013Chinese Science Bulletin2013,58,34:9
9Preliminary study on the living environment of hominids at the Donggutuo site,Nihewan Basin显示文摘The Donggutuo site, situated in the east margin of Nihewan basin, is one of the most important Paleolithic sites in China, characterized by the longest excavation seasons and the most abundant cultural remains recovered in the region. Based on well-constructed sporopollen, sediment grain size analysis, magnetic susceptibility, and iron oxide analysis of the 2000―2001 excavated section, four stages of environmental change in the Nihewan Beds are identified by the authors. The results indicate four major stages of environment and climate change from 1) warm and humid forest grass to 2) temperate and humid forest grass to 3) temperate and dry forest grass to 4) warm and humid forest, which is suitable for hominid occupation. The changes correspond to the stages of lake transgression and regression. The environment after the lake died out away has been cold and dry boschveld. The hominid activities at the site took place in the Early Pleistocene (1.10 Ma), which corresponds to the early three environmental stages. Therefore, it can be inferred that the early hominids adapted to the relatively low lake level episodes through activities involving sporadic stone tool making, procuring of raw materials for tools, concentrating stone artifacts, and hunting and butchering. In conclusion, the results will be of great significance to research regarding the relationship between hominid occupation and environmental changes as well as the adaptive behaviors of early humans at the Donggutuo site.PEI ShuWen LI XiaoLi LIU DeCheng MA Ning PENG Fei 2009Chinese Science Bulletin2009,54,21:7

11Paddy System with a Hybrid Rice Enhances Cyanobacteria Nostoc and Increases N2 Fixation显示文摘Biological nitrogen (N) fixation (BNF) plays a significant role in maintaining soil fertility in paddy field ecosystems. Rice variety influences BNF, but how different rice varieties regulate BNF and associated diazotroph communities has not been quantified. Airtight, field-based 15N2-labelling grow th chamber experiments were used to assess the BNF capac 辻 y of different rice varie ties. In addition, both the 16S rRNA and nifH genes were sequenced to assess the influence of different rice varieties on bacterial and diazotrophic communities in paddy soils. After subjecting a rice-soil system to 74 d of continuous airtight, field-based 15N2 labelling in pots in a growth chamber, the amounts of fixed N were 22.3 and 38.9 kg ha^-1 in inbred japonica (W23) and hybrid indica (IIY) rice cultivars plan ted in the rice-soil systems, respectively, and only 1%—2.5% of the fixed N was allocated to the rice plants and weeds. A greater abundance of diazotrophs was found in the surface soil (0-1 cm) under IIY than under W23. Sequencing of the 16S rRNA gene showed significantly greater abundances of the cyanobacterial genera Nostoc, Anabaena, and Cylindrospermum under IIY than under W23. Sequencing of the nifH gene also showed a significantly greater abundance of Nostoc under IIY than under W23. These results indicate that the hybrid rice cultivar (IIY) promoted BNF to a greater extent than the inbred rice cultivar (W23) and that the increase in BNF might have been due to the enhanced heterocystous cyanobacteria Nostoc.MA Jing BEI Qicheng WANG Xiaojie LIU Gang Georg CADISCH LIN Xingwu ZHU Jianguo SUN Xiaoli XIE Zubin 2019Pedosphere2019,29,3:7
12Hydrogen sulfide promotes flowering in heading Chinese cabbage by S-sulfhydration of BraFLCs显示文摘Heading Chinese cabbage(Brassica rapa L.syn.B.campestris L.ssp.chinensis Makino var.pekinensis(Rupr.)J.Cao et Sh.Cao)is a cruciferous Brassica vegetable that has a triplicate genome,owing to an ancient genome duplication event.It is unclear whether the duplicated homologs have conserved or diversi fied functions.Hydrogen sulfide(H_(2)S)is a plant gasotransmitter that plays important physiological roles in growth,development,and responses to environmental stresses.The modification of cysteines through S-sulfhydration is an important mechanism of H_(2)S,which regulates protein functions.H?S promotes flowering in Arabidopsis and heading Chinese cabbage.Here we investigated the molecular mechanisms of H_(2)S used to promote flowering in the latter.Four,five,and four BraFLC,BraSOC I,and BraFT homologs were identi fi ed in heading Chinese cabbage.Different BraFLC proteins were bound to different CArG boxes in the promoter regions of the BraSOC I and BraFT homologs,producing different binding patterns.Thus,there may be functionally diverse BraFLC homologs in heading Chinese cabbage.Exogenous H_(2)S at 100μmol L^(-1) significantly promoted flowering by compensating for insuf fi cient vernalization.BraFLC 1 and BraFLC_(3) underwent S-sulfhydration by H_(2)S,after which their abilities to bind most BraSOC I or BraFT promoter probes weakened or even disappeared.These changes in binding ability were consistent with the expression pattern of the BraFT and BraSOC I homologs in seedlings treated with H_(2)S.These results indicated that H_(2)S signaling regulates flowering time.In summary,H_(2)S signaling promoted plant flowering by weakening or eliminating the binding abilities of BraFLCs to downstream promoters through S-sulfhydration.Xiaoli Ma Liping Zhang Zhuoya Pei Linlin Zhang Zhiqiang Liu Danmei Liu Xuefeng Hao Zhuping Jin Yanxi Pei 2021Horticulture Research2021,8,1:6
13Pathological and molecular examinations of postmortem testis biopsies reveal SARS-CoV-2 infection in the testis and spermatogenesis damage in COVID-19 patients显示文摘In late December 2019,the novel severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),which causes coronavirus disease 2019(COVID-19),was identified in Wuhan,China,and the ensuing pandemic has led to more than 50 million infected individuals and more than one million deaths by November 10,2020(http://gffzze7c39cdc9e894ca6s9oxkuxw5o9vv6okw.ffgz.tsg.suse.edu.cn/).Pathologic investigations of autopsy tissue have focused primarily on the lung,heart,and kidney,whereas morphologic data on testis injury and the effects of SARS-CoV-2 infection on spermatogenesis are limited.Although two groups did not detect SARS-CoV-2 in the semen or testes of recovered COVID-19 patients,1,2 another group confirmed SARS-CoV-2 in the semen of patients.3 Therefore,it is currently unknown whether SARS-CoV-2 infection impacts spermatogenesis and male fertility.In the present study,we evaluated the effects of SARS-CoV-2 infection on spermatogenesis by examining the pathophysiology and molecular features of testes obtained from five male COVID-19 patients at autopsy.Xixiang Ma Chuhuai Guan Rong Chen Yunyun Wang Shenglei Feng Rongshuai Wang Guoqiang Qu Sijia Zhao Fengli Wang Xiaoli Wang Dingyu Zhang Liang Liu Aihua Liao Shuiqiao Yuan 2021Cellular & Molecular Immunology2021,18,2:6
14Single-Crystalline In Ga As Nanowires for Room-Temperature High-Performance Near-Infrared Photodetectors显示文摘In Ga As is an important bandgap-variable ternary semiconductor which has wide applications in electronics and optoelectronics. In this work, single-crystal In Ga As nanowires were synthesized by a chemical vapor deposition method.Photoluminescence measurements indicate the In Ga As nanowires have strong light emission in near-infrared region. For the first time, photodetector based on as-grown In Ga As nanowires was also constructed. It shows good light response over a broad spectral range in infrared region with responsivity of 6.5×10~3 AW^(-1) and external quantum efficiency of 5.04×10~5%. This photodetector may have potential applications in integrated optoelectronic devices and systems.Huang Tan Chao Fan Liang Ma Xuehong Zhang Peng Fan Yankun Yang Wei Hu Hong Zhou Xiujuan Zhuang Xiaoli Zhu Anlian Pan 2016Nano-Micro Letters2016,8,1:6
15Comparative genomic and transcriptomic analyses uncover the molecular basis of high nitrogen-use efficiency in the wheat cultivar Kenong 9204显示文摘Studying the regulatory mechanisms that drive nitrogen-use efficiency(NUE)in crops is important for sustainable agriculture and environmental protection.In this study,we generated a high-quality genome assembly for the high-NUE wheat cultivar Kenong 9204 and systematically analyzed genes related to nitrogen uptake and metabolism.By comparative analyses,we found that the high-affinity nitrate transporter gene family had expanded in Triticeae.Further studies showed that subsequent functional differentiation endowed the expanded family members with saline inducibility,providing a genetic basis for improving the adaptability of wheat to nitrogen deficiency in various habitats.To explore the genetic and molecular mechanisms of high NUE,we compared genomic and transcriptomic data from the high-NUE cultivar Kenong 9204(KN9204)and the low-NUE cultivar Jing 411 and quantified their nitrogen accumulation under high-and low-nitrogen conditions.Compared with Jing 411,KN9204 absorbed significantly more nitrogen at the reproductive stage after shooting and accumulated it in the shoots and seeds.Transcriptome data analysis revealed that nitrogen deficiency clearly suppressed the expression of genes related to cell division in the young spike of Jing 411,whereas this suppression of gene expression was much lower in KN9204.In addition,KN9204 maintained relatively high expression of NPF genes for a longer time than Jing 411 during seed maturity.Physiological and transcriptome data revealed that KN9204 was more tolerant of nitrogen deficiency than Jing 411,especially at the reproductive stage.The high NUE of KN9204 is an integrated effect controlled at different levels.Taken together,our data provide new insights into the molecular mechanisms of NUE and important gene resources for improving wheat cultivars with a higher NUE trait.Xiaoli Shi Fa Cui Xinyin Han Yilin He Long Zhao Na Zhang Hao Zhang Haidong Zhu Zhexin Liu Bin Ma Shusong Zheng Wei Zhang Jiajia Liu Xiaoli Fan Yaoqi Si Shuiquan Tian Jianqing Niu Huilan Wu Xuemei Liu Zhuo Chen Deyuan Meng Xiaoyan Wang Liqiang Song Lijing Sun Jie Han Hui Zhao Jun Ji Zhiguo Wang Xiaoyu He Ruilin Li Xuebin Chi Chengzhi Liang Beifang Niu Jun Xiao Junming Li Hong-Qing Ling 2022Molecular Plant2022,15,9:6
16Advertisement Call Variability in the Black-spined Toad Bufo melanostictus (Anura: Bufonidae) during the Breeding Season in Lishui, Zhejiang, China显示文摘Advertisement calls play an important role in influencing female mate choice and are regarded as one of the key characters responsible for reproductive isolation and speciation events in frogs and toads. The black-spined toad, Bufo melanostictus, is one of the most common amphibians in Southeast Asia and is frequently observed in human habitations throughout its distributional range. The advertisement calls of the toad have not been well described. Here, we report the advertisement calls of this species from Lishui, Zhejiang, China during its breeding season. The advertisement calls of B. melanostictus are composed of single notes with a single harmonic frequency emitted sporadically. The call parameters recorded in this study were highly variable across recording times and with different body sizes. Dominant frequency was negatively correlated with body size. Comparing the calls of the B. melanostictus population from Lishui with the populations from five other localities(Bangkok, Thailand; Coorg, India; Burma, Myanmar; Bali, Indonesia; Halimun-Salak National Park, Indonesia), we found that call structure was similar among five different populations with no harmonics, while the Halimun-Salak National Park population contained two clear harmonics. Dominant frequency was similar between Bali(1.56 kHz) and Coorg(1.6 kHz) populations, while it was highly variable among other populations. Besides call duration, call interval and pulse/call rate may also be significantly different among the comparing populations. Pooling the available data, we observed some similarities and differences in call parameters among the six populations.Li WEI Lihua ZHAO Xiaohao MA Xiaoli FAN Xiaomei MA Zhihua LIN 2012Asian Herpetological Research2012,3,2:6

19DICER1 mutations in twelve Chinese patients with pleuropulmonary blastoma显示文摘Our aim is to examine the impact of DICER1 mutations on the pathogenesis of pleuropulmonary blastoma(PPB) by evaluating the mutation frequency and investigating the family history of Chinese patients with PPB. The family histories of 12 children with PPB recruited consecutively were surveyed. Blood samples from patients and their first-degree relatives were tested for DICER1 mutations. Whole-genome sequencing of blood samples and formalin-fixed and paraffin-embedded(FFPE) tumor tissue was performed in one family with twins. Twelve patients with PPB included six type II and six type III cases. Seven of the12 patients harbored DICER1 mutations, six of which were frameshift or nonsense mutations. Another case carried a germline DICER1 mutation affecting the splice site. FFPE sample had a nonsense mutation in TDG and missense mutations in DICER1.In addition, two cases with DICER1 mutations were found to have lung cysts preceding the diagnosis of PPB. Furthermore, one patient had a family history remarkable for thyroid diseases. Our results indicate that the germline mutation frequency in Chinese patients with PPB is similar to the ones reported for patients from USA, UK, and Japan. Moreover, our study strongly suggests that investigating the family history and detecting germline DICER1 mutations might be of benefit to increasing awareness and improving the accuracy of the differential diagnosis of PPB from non-malignant lung cysts.Siyu Cai Xisi Wang Wen Zhao Libing Fu Xiaoli Ma Xiaoxia Peng 2017Science China(Life Sciences)2017,60,7:5
20AFM quantitative analysis and determination of shear angle of {259}_f martensitic surface relief显示文摘An attentive observation and quantitative analysis of {259}f martensitic surface relief in an Fe-23Ni-0.55C alloy are made by means of an atomic force microscope (AFM), and different martensitic variants' shear angles are determined in this paper. The experiments show that {259}f martensitic surface relief exhibits regular shape in many cases, which is in agreement with the prediction of invariant plane strain (IPS). Generally, {259}f martensitic surface relief appears to be 'N'-shaped, but it is tent-shaped in the case of zigzag-shaped martensite. The compressed deformation of parent phase diminishes the surface relief in size but with little change of its relief angle. {259}f martensitic surface relief, large or small, has approximately the same relief angles, exhibiting a good 'self-similar fractal'. The determined values of different {259}f martensitic variants' shear angles are in fine agreement with the prediction of Wechsler-Liberman-Read (W-L-R) theory, with only a slight difference of less than 3.65°.LIN Xiaoping, GU Nanju, ZHANG Yong, MENG Zhaowei and MA Xiaoli(Department of Materials Science and Technology, Hebei University of Technology, Tianjin 300130, China) 2002Progress in Natural Science:Materials International2002,12,10:5
