1Dissection of genetic overlap of salt tolerance QTLs at the seedling and tillering stages using backcross introgression lines in rice显示文摘QTLs for salt-tolerance(ST)related traits at the seedling and tillering stages were identified using 99 BC2F8 introgression lines(IL)derived from a cross between IR64(indica)as a recurrent parent and Binam(japonica)from Iran as the donor parent.Thirteen QTLs affecting survival days of seedlings(SDS), score of salt toxicity of leaves(SST),shoot K + concentration(SKC)and shoot Na + concentration(SNC) at the seedling stage and 22 QTLs underlying fresh weight of shoots(FW),tiller number per plant(TN) and plant height(PH)at the tillering stage were identified.Most QTLs detected at the tillering stage showed obvious differential expression to salt stress and were classified into three types based on their differential behaviors.Type I included 11 QTLs which were expressed only under the non-stress condition.Type II included five QTLs expressed in the control and the salt stress conditions,and three of them(QPh5,QPh8 and QTn9)had similar quantity and the same direction of gene effect,suggesting their expression was less influenced by salt stress.Type III included six QTLs which were detectable only under salt stress,suggesting that these QTLs were apparently induced by the stress.Thirteen QTLs affecting trait difference or trait stability of ILs between the stress and non-stress conditions were identified and the Binam alleles at all loci except QPh4,QTn2 and QFw2a decreased trait difference.The three QTLs less influenced by the stress and 13 QTLs affecting trait stability were considered as ST QTLs which contributed to ST.Comparing the distribution of QTLs detected at the seedling and tillering stages,most(69%)of them were genetically independent.Only four were the same or adjacent regions on chromosomes 1,2,8 and 11 harboring ST QTLs detected at the two stages,suggesting that partial genetic overlap of ST across the two stages occurs.It is likely,therefore,to develop ST rice variety for both stages by pyramiding of ST QTLs of different stages or selection against the overlapping QTLs between the two stages via marker-assisted selection(MAS).ZANG JinPing 1 ,SUN Yong 1 ,WANG Yun 1 ,YANG Jing 1 ,LI Fang 1 ,ZHOU YongLi 1 ,ZHU LingHua 1 , Reys JESSICA2,Fotokian MOHAMMADHOSEIN 2,XU JianLong 1&LI ZhiKang 1,2 1Institute of Crop Sciences/National Key Facility for Crop Gene Resources&Genetic Improvement,Chinese Academy of Agricul- tural Sciences,Beijing 100081,China 2International Rice Research Institute,DAPO Box 7777,Metro Manila,Philippines 2008Science China(Life Sciences)2008,51,7:32
2Effect of coal levels during direct reduction roasting of high phosphorus oolitic hematite ore in a tunnel kiln显示文摘The effect of coal levels on phosphorus removal from a high phosphorus oolitic hematite ore after direct reduction roasting have been investigated. Raw ore, coal, and a dephosphorization agent were mixed and the mixture was then roasted in a tunnel kiln. The roasted products were treated by two stages of grinding followed by magnetic separation. XRD and SEM-EDS examination of the products was used to analyze differences in the roasted products. The results show that coal is one of the most important factors affecting the direct reduction roasting process. When the inner coal levels increased from 0% to 15% the iron grade decreased linearly from 94.94% to 88.81% and the iron recovery increased from 55.94% to 92.94%. At the same time the phosphorus content increased from 0.045% to 0.231%. Increasing the inner coal levels also caused more hematite to be reduced to metallic iron but the oolitic structure of the roasted product was preserved in the presence of high coal loading. The phase of the phosphorus in raw ore was not changed after direct reduction roasting. The effect of coal on the phosphorus content in the H-concentrate arises from changes in the difficulty of mechanically liberating the metallic iron from the phosphorus bearing minerals.Li Yongli Sun Tichang Zou Anhua Xu Chengyan 2012International Journal of Mining Science and Technology2012,22,3:22
3Effect of stimulating acupoint Guanyuan(CV 4) on lower back pain by burning moxa heat for different time lengths: a randomized controlled clinical trial显示文摘OBJECTIVE: To investigate the effect of different heat-stimulating time lengths on lower back pain.METHODS: Forty participants were randomly assigned to four groups of various heating time lengths. The short heating time length group(SL),moderate heating time length group(ML), and long heating time length group(LL) respectively received 15, 30, and 60 min of moxibustion therapy stimulating the acupoint Guanyuan(CV 4). The conventional acupuncture group(CA) received needle acupuncture treatment as a control group. The participants were treated continuously over a 2-week treatment period for a total of 10 sessions, with five sessions given per week. Participants were assessed weekly by blinded assessors, using the visual analogue scale(VAS) and Roland Morris Questionnaire(RMQ).RESULTS: The VAS and RMQ scores reduced in all four groups during treatment. There were significant differences in VAS scores(P < 0.01) and RMQ scores(P < 0.01) between before treatment and after 2 weeks of treatment in the LL group. After treatment, the LL group reported significantly lower VAS scores compared with the CA group, ML group,and SL group(P < 0.05).CONCLUSION: The long and moderate lengths of heat-stimulating time of 30 and 60 min may be more effective for relieving lower back pain than that of short stimulating time lengths.Xu Jianfeng Lin Ruizhu Wu Yongli Wang Yingxu Liu Jian Zhang Yanling Zhang Yuequan Xi Chaolei Wu Qiang Li Xinjian 2015Journal of Traditional Chinese Medicine2015,35,1:13
4The biological effect of recombinant humanized collagen on damaged skin induced by UV-photoaging:An in vivo study显示文摘The application of medical devices to repair skin damage is clinically accepted and natural polymer enjoys an important role in this field,such as collagen or hyaluronic acid,etc.However,the biosafety and efficacy of these implants are still challenged.In this study,a skin damage animal model was prepared by UV-photoaging and recombinant humanized type Ⅲ collagen(rhCol Ⅲ)was applied as a bioactive material to implant in vivo to study its biological effect,comparing with saline and uncrosslinked hyaluronic acid(HA).Animal skin conditions were non-invasively and dynamically monitored during the 8 weeks experiment.Histological observation,specific gene expression and other molecular biological methods were applied by the end of the animal experiment.The results indicated that rhCol Ⅲ could alleviate the skin photoaging caused by UV radiation,including reduce the thickening of epidermis and dermis,increase the secretion of Collagen Ⅰ(Col Ⅰ)and Collagen Ⅲ(Col Ⅲ)and remodel of extracellular matrix(ECM).Although the cell-material interaction and mechanism need more investigation,the effect of rhCol Ⅲ on damaged skin was discussed from influence on cells,reconstruction of ECM,and stimulus of small biological molecules based on current results.In conclusion,our findings provided rigorous biosafety information of rhCol Ⅲ and approved its potential in skin repair and regeneration.Although enormous efforts still need to be made to achieve successful translation from bench to clinic,the recombinant humanized collagen showed superiorities from both safety and efficacy aspects.Jing Wang He Qiu Yang Xu Yongli Gao Peijie Tan Rui Zhao Zhanhong Liu Yajun Tang Xiangdong Zhu Chongyun Bao Hang Wang Hai Lin Xingdong Zhang 2022Bioactive Materials2022,7,5:7
5A brief introduction to the FUTang Updating medical REcords(FUTURE)database显示文摘Introduction Futang Research Center of Pediatric Development(FRCPD),the first nonprofit social service organization engaging in pediatric research in China,was founded in May 2013.Until August 2021,FRCPD has 40 tertiary children’s hospitals,accounting for about 65.6%of all national public children’s hospitals,which was reported to be 61 in China Health Statistical Yearbook(2020).The hospitals are distributed in 30 provinces,autonomous regions,and municipalities(except for Tibet autonomous region),and most of them are in the capital of the province,forming a broad frontline representing the best quality of health care for the diagnosis and treatment of children’s disease in China.Based on the idea of sharing,FRCPD realized the exchange of experts,medical resources,research findings,educational events,preventive strategies,and management experiences among members.In the long run,FRCPD aims to continuously promote the quality of healthcare and medical service capability for children in China.Xinyu Wang Yueping Zeng Jian Tian Hui Xu Fei Song Yongli Guo Xin Xu Guoshuang Feng Xin Ni 2021Pediatric Investigation2021,5,3:6
6Effect of acupuncture anesthesia on acne vulgaris of pricking-blood-letting cupping: a single-blind randomized clinical trail显示文摘OBJECTIVE: To evaluate the effect on acne vulgaris of pricking-bloodletting cupping at Dazhui(GV 14) under acupuncture anesthesia, and establish whether providing anesthesia to the treatment area by manipulating Hegu(LI 4) and Quchi(LI 11) might have an additional therapeutic benefit. METHODS: Thirty-eight patients were recruited and randomized into a control group and an intervention group with a single-blind(observer-blind) method. The control group was treated by pricking-bloodletting cupping at Dazhui(GV 14) and the studied group by pricking-bloodletting cupping at Dazhui(GV 14) under acupuncture anesthesia at Hegu(LI 4) and Quchi(LI 11). Both groups were treated twice weekly for 6 weeks. The analgesic and therapeutic effects of acupuncture were evaluated on a visual analog scale(VAS) and global acne grading system(GAGS), respectively.RESULTS: There were differences in the VAS scores of pain on pricking and in the pricked area, and the duration of pain between the groups. After 12 treatments, there was a significant reduction in GAGS scores from baseline in both groups, but there was no significant difference between the groups. CONCLUSION: Acupuncture anesthesia at Hegu(LI 4) and Quchi(LI 11) is an effective means of alleviating the pain of pricking-bloodletting cupping and reducing the duration of pain in the treatment area. Pricking-bloodletting cupping at Dazhui(GV 14) improves the skin lesions of patients with moderate acne vulgaris, but acupuncture anesthesia does not appear to have an additional therapeutic effect.Jianfeng Xu Ruizhu Lin Jing Wang Yongli Wu Yingxu Wang Yuequan Zhang Chaolei Xi Qiang Wu 2013Journal of Traditional Chinese Medicine2013,33,6:6

8A mutation in the type Ⅱ hair keratin KRT86 gene in a Han family with monilethrix显示文摘Monilethrix, a congenital disease of hair, is usually associated with mutations in keratin genes, like KRT81, KRT83 and KRT86. We conducted this study to investigate the mutation of type Ⅱ human basic hair keratin hHb/ KRT gene in a Han family with monilethrix and obtain information for potential pathogenic mechanism study of monilethrix. Peripheral blood samples were drawn for genomic DNA detection. Exon 1 and exon 7 of the KRT81, KRT83 and KRT86 genes were amplified by PCR. All PCR products were sequenced directly using an ABI 310 DNA sequencer. These sequences were aligned with the standard sequences in GenBank using the BLAST software. PCR products were digested with restriction endonuclease and restriction fragment length polymorphism (RFLP) analysis was performed. In this study, we identified one novel mutation, which is a heterozygous transitional mutation of G→A at position 1,289 in exon 7 of the KRT86 gene [R430Q (KRT86)]. RFLP assays for the novel mutation excluded the possibility of polymorphism. The R430Q mutation of the KRT86 gene may be pathogenic for monilethrix. Meanwhile, we did not find any novel mutation or recurrent mutation in exons 1 and 7 of KRT81 and KRT83 and exon 1 of KRT86. There is a potential pathogenic gene in the subjects and our results expand the spectrum of mutations in the hHb6 gene.Jin Wu Yongli Lin Wenrong Xu Zhongming Li Weixin Fan 2011The Journal of Biomedical Research2011,25,1:4
9Prognostic value of systemic immune- inflammation index in acute/subacute patients with cerebral venous sinus thrombosis显示文摘Objective To evaluate the prognosis values of systemic immune-inflammation index(SII)in non-chronic cerebral venous sinus thrombosis(CVST).Methods patients with CVST,admitted to the First Affiliated Hospital of Zhengzhou University,were retrospectively identified from January 2013 to December 2018.We selected patients in acute/subacute phase from database.Functional outcomes of patients were evaluated with the modified Rankin Scale(mRS)-mRS 3-6 as poor outcomes and mRS 6 as death.The overall survival time was defined as the date of onset to the date of death or last follow-up date.Survival analysis was described by the Kaplan-Meier curve and Cox regression analysis.Multivariate logistic regression analysis assessed the relationship between SII and poor functional outcome.The area under the Receiver Operating Curve curve(AUC)was estimated to evaluate the ability of SII in prediction.Results A total of 270 patients were included and their duration of follow-up was 22 months(6-66 months),of whom 31 patients had poor outcomes and 24 patients dead.Cox regression analysis showed that SII(HR=1.304,95%CI:1.101 to 1.703,p=0.001)was a predictor of death in non-chronic CVST.Patients with higher SII presented lower survival rates(p=0.003).The AUC of SII was 0.792(95%CI:0.695 to 0.888,p=0.040)with a sensitivity of 69.6%and specificity of 80.1%.Subgroups analysis demonstrated that SII was an important predictor of poor outcomes in male(OR=1.303,95%CI:1.102 to 1.501,p=0.011)and pregnancy/puerperium female(OR=1.407,95%CI:1.204 to 1.703,p=0.034).Conclusions SII was a potential predictor in the poor prognosis of patients with acute/subacute CVST,especially in male and pregnancy/puerperium female.Shen Li Kai Liu Yuan Gao Lu Zhao Rui Zhang Hui Fang Yongli Tao Hongbing Liu Jiawei Zhao Zongping Xia Yuming Xu Bo Song 2020Stroke & Vascular Neurology2020,5,4:3
10Identification and characterization of the cellular subclones that contribute to the pathogenesis of mantle cell lymphoma显示文摘Mantle cell lymphoma(MCL)is a B-cell malignancy with poor clinical outcome and undefined pathogenesis.Development of clinically relevant cellular models for MCL research is an urgent need.Our preliminary observations lead the development of two novel hypotheses that we tested in this study:1.multicellular spheroid might be a unique growth mode of earlystage cells in MCL;2.MCL might be a polyclonal tumor.We made the following original observations that have not been reported:First,we have provided a new experiment method for enriching MCL early-stage cells and characterized the spheroid mode of growth as a unique feature of early-stage MCL cells in cell line as well as in clinical samples.Second,we have established a clinically relevant cellular model of MCL,the JeKo-1-spheroid cell line,that was highly enriched in early-stage sub-clones.JeKo-1-spheroid cells and the spheroid growing cells enriched from MCL patients exhibited comparably enhanced tumorigenic abilities and similar biological features.Third,Immunophenotypic analysis has revealed that MCL may be derived from precursor-B(pre-B),immature-B and mature-B cells,not only the mature-B cells as WHO classified in 2016.Fourth,MCL may be a polyclonal disease composed of CD19e/IgMe,CD19 e/IgMt,CD19t/IgMt three sub-clones,of which the CD19e/IgMt sub-clone might be the dominant sub-clone with the strongest tumorigenic ability.Fifth,CD19t/IgMe that differentiates MCL and normal B cells may represent a new marker for MCL early detection,minor residual disease monitoring after therapies and prognosis.Junling Tang Li Zhang Tiejun Zhou Zhiwei Sun Liangsheng Kong Li Jing Hongyun Xing Hongyan Wu Yongli Liu Shixia Zhou Jingyuan Li Mei Chen Fang Xu Jirui Tang Tao Ma Min Hu Dan Liu Jing Guo Xiaofeng Zhu Yan Chen Ting Ye Jianyu Wang Xiaoming Li H.Rosie Xing 2019Genes & Diseases2019,6,4:2
11Interactions between cytokinin and nitrogen contribute to grain mass in wheat cultivars by regulating the flag leaf senescence process显示文摘Premature senescence after anthesis reduces crop yields.Delaying leaf senescence could maintain photosynthetic activity for a longer period and lead to a higher photosynthetic rate.Recent studies have provided some insights into the interaction between cytokinin and nitrogen(N)in the regulation of plant development.In the present study,foliar application of exogenous 6-benzylaminopurine(6-BA)and lovastatin,an inhibitor of cytokinin synthesis,was combined with three N rates[0 kg ha^(-1)(low nitrogen,LN),240 kg ha^(-1)(normal nitrogen,NN),and 360 kg ha^(-1)(high nitrogen,HN)]in two wheat cultivars,Wennong 6(with a staygreen phenotype)and Jimai 20(with a non-staygreen phenotype).Flag leaf senescence was assessed using a Gompertz growth curve.Grain mass,dry matter accumulation and distribution,total N of flag leaf,and concentrations of zeatin riboside(ZR)and abscisic acid(ABA)were also used to evaluate the functional characteristics of flag leaves.Grain mass was negatively correlated with initial senescence rate(r_0)and duration of rapid chlorophyll loss(Chl_(loss)),whereas it was positively correlated with maximum senescence rate(r_(max)),average senescence rate(r_(aver)),persistence phase(Chl_(per)),total duration of flag leaf(Chl_(total))and inflection point cumulative temperature(M).Compared to Jimai 20,Wennong 6 had larger r_(aver),Chl_(per),and Chl_(total).The concentration of ZR was highest under the 6-BA×NN treatment,followed by the 6-BA×HN and 6-BA×LN treatments.However,the concentration of ABA showed the opposite trend.It was concluded that the staygreen phenotype Wennong 6 was associated with greater grain mass and altered cytokinin metabolism and could be classified as a functional staygreen type.Foliar application of 6-BA interacting with N at the NN level(240 kg ha^(-1))may be a beneficial strategy for improving grain yield of wheat by regulating endogenous hormones and the flag leaf senescence process.Increasing endogenous cytokinin promoted the transport of dry matter to grain.Yongli Luo Yuhai Tang Xin Zhang Wenqian Li Yonglan Chang Dangwei Pang Xu Xu Yong Li Zhenlin Wang 2018The Crop Journal2018,6,5:2
12Flow characteristics and reaction properties of carbon dioxide in microtubules and porous media显示文摘Carbon dioxide reacts with porous media while flowing through them enhancing their permeability.Its flow behavior as well as the permeability enhancement effects were studied in synthetic cores,natural cores and microtubes with an inner diameter of 5 μm.The results show that the permeability of H2O-saturated cores(containing carbonate ingredients) was enhanced by increasing the injection volume of a CO2-H2O solution.This enhancement is attributable to carbon dioxide's corrosion,which is justified by SEM scanning.The same phenomenon occurs with a CO2-H2O solution in microtubes,but for a different reason.The gas flow velocity of carbon dioxide in microtubes was approximately 100% faster than that of nitrogen because of the scale and the squeezing effects.Carbon dioxide molecules dissolved in water accelerate the diffusion rate of water molecules within the boundary layer,which in turn diminishes the thickness of the water film and enlarges the effective pore size.This flow behavior facilitates the injection of carbon dioxide into low-permeability reservoirs for oil-displacement and formation energy buildup purposes.This behavior also increases the potential for carbon dioxide channeling or release from the formation.ZHAO RenBao YUE XiangAn WU YaHong XU ShaoLiang WANG Fei HOU YongLi 2008Chinese Science Bulletin2008,53,21:2
13The Msi1-mTOR pathway drives the pathogenesis of mammary and extramammary Paget’s disease显示文摘Mammary and extramammary Paget’s Diseases(PD)are a malignant skin cancer characterized by the appearance of Paget cells.Although easily diagnosed,its pathogenesis remains unknown.Here,single-cell RNA-sequencing identified distinct cellular states,novel biomarkers,and signaling pathways—including mTOR,associated with extramammary PD.Interestingly,we identified MSI1 ectopic overexpression in basal epithelial cells of human PD skin,and show that Msi1 overexpression in the epidermal basal layer of mice phenocopies human PD at histopathological,single-cell and molecular levels.Using this mouse model,we identified novel biomarkers of Paget-like cells that translated to human Paget cells.Furthermore,single-cell trajectory,RNA velocity and lineage-tracing analyses revealed a putative keratinocyte-to-Paget-like cell conversion,supporting the in situ transformation theory of disease pathogenesis.Mechanistically,the Msi1-mTOR pathway drives keratinocyte-Paget-like cell conversion,and suppression of mTOR signaling with Rapamycin significantly rescued the Paget-like phenotype in Msi1-overexpressing transgenic mice.Topical Rapamycin treatment improved extramammary PD-associated symptoms in humans,suggesting mTOR inhibition as a novel therapeutic treatment in PD.Yongli Song Christian F.Guerrero-Juarez Zhongjian Chen Yichen Tang Xianghui Ma Cong Lv Xueyun Bi Min Deng Lina Bu Yuhua Tian Ruiqi Liu Ran Zhao Jiuzhi Xu Xiaole Sheng Sujuan Du Yeqiang Liu Yunlu Zhu Shi-jun Shan Hong-duo Chen Yiqiang Zhao Guangbiao Zhou Jianwei Shuai Fazheng Ren Lixiang Xue Zhaoxia Ying Xing Dai Christopher J.Lengner Bogi Andersen Maksim V.Plikus Qing Nie Zhengquan Yu-Show 2020Cell Research2020,30,10:2

18Preparation and Identification of Monoclonal Antibodies Against Vibrio anguillarum显示文摘Monoclonal antibodies (Mabs) against V.anguillarum strain M3 are prepared, and their isotypes are also characterized. Among them, C1C5 is the only Mab which does not crossreact with other eleven non-V.anguillarum strains. The proteinase K digestion test shows that the epitopes recognized by C1C5, C6C3 and C6C32 Mabs contained protein. The periodate oxidation test showed that the epitopes recognized by Mabs except C1C5 are glycosylated. In addition, results of additivity test indicate that the epitopes recognized by C6C3 and C6C32 Mabs are similar, and quite different from those recognized by Mab C1C5.陈师勇 Zhang Peijun Mo Zhaolan Zhang Zhendong Zou Yuxia Xu Yongli 2004High Technology Letters2004,10,1:1
19A Novel 28 GHz Phased Array Antenna for 5G Mobile Communications显示文摘A novel phased array antenna consisting of 256 elements is presented and experimentally verified for 5G millimeter-wave wireless communications.The antenna integrated with a wave control circuit can perform real-time beam scanning by reconfiguring the phase of an antenna unit.The unit,designed at 28 GHz using a simple patch structure with one PIN diode,can be electronically controlled to generate 1 bit phase quantization.A prototype of the antenna is fabricated and measured to demonstrate the feasibility of this approach.The measurement results indicate that the antenna achieves high gain and fast beam-steering,with the scan beams within±60°range and the maximum gain up to 21.7 dBi.Furthermore,it is also tested for wireless video transmission.In ZTE Shanghai,the antenna was used for the 5G New Radio(NR)test.The error vector magnitude(EVM)is less than 3%and the adjacent channel leakage ratio(ACLR)less than−35 dBc,which can meet 5G system requirements.Compared with the conventional phased array antenna,the proposed phased array has the advantages of low power consumption,low cost and conformal geometry.Due to these characteristics,the antenna is promising for wide applications in 5G millimeter-wave communication systems.LI Yezhen REN Yongli YANG Fan XU Shenheng ZHANG Jiannian 2020ZTE Communications2020,18,3:1
