1Development of gene-tagged molecular markers for starch synthesis-related genes in rice显示文摘Improving grain quality is an important goal in breeding new elite rice varieties,requiring effective tools for the identification of target genotypes.Molecular marker-aided selection(MAS),combined with conventional breeding approaches,enables us to pre-cisely identify the individual genotypes that are associated with different grain quality features,which can dramatically improve the breeding efficiency.However,to date,the number of molecular markers used in MAS for grain quality improvement is still somewhat limited.In this study,based on our previous study that rice grain quality is strongly associated with starch synthesis in the endosperm,we developed 51 gene-tagged molecular markers according to sequence variations in 18 starch synthesis-related genes from 16 typical rice cultivars.These markers can discriminate the different alleles among rice germplasms.These novel markers will provide effective tools in improving grain quality via the breeding new elite rice varieties.TIAN ZhiXi YAN ChangJie QIAN Qian YAN Song XIE HuiLan WANG Fang XU JieFen LIU GuiFu WANG YongHong LIU QiaoQuan TANG ShuZhu LI JiaYang GU MingHong 2010Chinese Science Bulletin2010,55,33:12
2Risk factors of CMV infection in patients after umbilical cord blood transplantation: a multicenter study in China显示文摘Objective:This retrospective study examined risk factors for cytomegalovirus(CMV)infection after umbilical cord blood transplantation(UCBT)and the impact of CMV infection on patient survival.Methods:In all 176 patients,plasma CMV DNA was negative prior to the transplantation,and examined twice a week for 100 d,and then once weekly for additional 300 d.Preemptive antiviral therapy(ganciclovir or foscarnet)was started in patients with>1,000/mL copies of CMV DNA but no full-blown CMV disease,and was discontinued upon two consecutive negative reports of blood CMV DNA test.The survival and risk factors for CMV infection or disease were examined using logistic regression.Results:CMV infection developed in 71%(125/176)of the patients,with a median onset of 32 d.Four patients(2.3%)developed CMV disease.Neither the 5-year overall survival(OS)nor event-free survival(EFS)differed significantly in infected patients vs.those with no infection(59.4%vs.64.8%,P=0.194;53.4%vs.59.1%,P=0.226).A stepwise multivariate analysis indicated an association of CMV infection with age,high-dose glucocorticoids,the number of transplanted CD34+cells,and the number of platelet transfusion,but not with gender,the conditioning regimen,and the day of neutrophil recovery and chronic graft-versushost disease(cGVHD).Conclusions:CMV infection is very common after UCBT,but does not seem to affect long-term survival with preemptive antiviral treatment.Juan Tong Zimin Sun Huilan Liu Liangquan Geng Changcheng Zheng Baolin Tang Kaidi Song Wen Yao Xin Liu 2013Chinese Journal of Cancer Research2013,25,6:8
3Comparative 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
4The role of personality,social economic and prevention strategy effects on health-related quality of life among people living with HIV/AIDS显示文摘Background::HIV/AIDS has transformed into a chronic controllable but not yet curable infectious disease as other chronic diseases to some extent.The additional of so called fourth 90%that included the improved health-related quality of life(HRQoL)for people living with HIV(PLWHIV)required solutions beyond antiretroviral therapy and viral load suppression.This study will explore the role of personality,social economic and prevention strategy effection on HRQoL among people living with HIV/AIDS.Methods::A cross-sectional study was conducted among PLWHIV aged more than 16 years old in the 10 municipalities in Yunnan Province,China from October 2019 to May 2020,enrolling total 1997 participants.Individual-level HRQoL data were measured by 12-item Short Form Health Survey(SF-12)and EuroQol Five Dimensions Questionnaire(EQ-5D-5L).We assembled municipal-level data about social economic from Yunnan Statistical Yearbook in 2020 and strategy practice information from the self-evaluation system.We used the principal component analysis to build the social economic and strategy effect on each area respectively and one-way ANOVA was used to perform univariate analysis to identify the predictors with significant differences.Finally we used multi-level model(MLM)to explore the personality,social economic and strategy effects in health-related quality of life among PLWHIV.Results::The global score for quality of life measured using EQ-5D-5L had an estimated mean score(standard deviation,SD)of 0.901±0.146.The HRQoL score measured using PCS-12 had an estimated mean score(SD)of 46.62±8.55.The mean MCS-12 score(SD)was estimated to be 47.80±9.71.The area-level predictors explained a proportion of 13.6-17.2%for the between-area variation of the HRQoL scores,regardless of the total HRQoL,physical component and mental component.The impacts of stigma(P<0.01),social support(P<0.001),anxiety(P<0.001),depression(P<0.05)and social economic status(P<0.05)on HRQoL at the individual-level were significantly different.The plots visualized the impact of individual-level factors on a respondent’s HRQoL was modified by the area-level characteristics.Conclusions::The study identified the possible strategy determinant of individual HRQoL of PLWHIV and also the area effect on HRQoL.Stigma,social support,anxiety,depression and social economic status were the individual-level determinants on HRQoL.These could be a valuable resource for evaluating the overall health of the areas and help improve local decision making.Xiaowen Wang Hongbing Luo Enlong Yao RenhaiTang Wenbin Dong Fuyong Liu Jun Liang Huilan Li Minyang Xiao Zuyang Zhang Jin Niu Lijun Song Liru Fu Xuehua Li Shicong Qian Qing Guo Zhizhong Song 2021Infectious Diseases of Poverty2021,10,4:3
5Biocompatible, small-sized and well-dispersed gold nanoparticles regulated by silk fibroin fiber from Bombyx mori cocoons显示文摘Biocompatible, small-sized but well-dispersed gold nanoparticles (Au NPs) remain a major challenge for their synthesis. Here a convenient solution impregnation technique is developed to prepare such Au NPs under the regulation of degummed silk fibroin fibers (SFFs) extracted from Bombyx mori cocoons. SFFs play multiple roles in the formation of Au NPs such as reactive substrate to capture AuCl4^- ions by the chelation of -C = 0, reducing agent for Au(0) by the reduction of -OH , and modifiers to render biocompatible Au NPs by some functional groups and biomolecules. The as-prepared Au NPs with a size of 7-10 nm are embedded in the solid SFF substrate, and can disperse well in the liquid system by the disintegration of SFFs into silk fibroin (SF) in a certain CaCl2 solution. The biocompatible Au NPs exhibit uniform small size and distribute stably in both solid and solution states, which have distinctive properties and functional advantages, and bring great convenience to their storage and transportation.Chengzhi YANG Shikun CHEN Huilan SU Haoyue ZHANG Jianfei TANG Cuiping GUO Fang SONG Wang ZHANG Jiajun GU Qinglei LIU 2019Frontiers of Materials Science2019,13,2:2

7Honeycomb-like g-C_(3)N_(4)/CeO_(2)-x nanosheets obtained via one step hydrothermal-roasting for efficient and stable Cr(Ⅵ) photo-reduction显示文摘Graphitic carbon nitride(g-C_(3)N_(4))-based materials are regarded as one of the most potential photocatalysts for utilizing solar energy.In this work,we reported a facile one step in-situ hydrothermal-roasting method for preparing honeycomb-like g-C_(3)N_(4)/CeO_(2) nanosheets with abundant oxygen vacancies(g-C_(3)N_(4)/CeO_(2)-x).The hydrothermal-roasting and incomplete-sealed state can(i)generate an in-situ reducing atmosphere(CO,N2,NH3) to tune the concentration of oxygen vacancies in CeO_(2);(ii) beneficial to prevent continuous growth of g-C_(3)N_(4) and results in honeycomb-like g-C_(3)N_(4)/CeO_(2)-x hybrid nanosheets.What is more,the g-C_(3)N_(4)/CeO_(2)-x photocatalyst exhibited extended photoresponse range,increased specific surface area and obviously enhanced separation efficiency of photogenerated electron-hole pairs.As a proof-of-concept application,the optimized g-C_(3)N_(4)/CeO_(2)-xnanosheets could achieve 98% removal efficiency for Cr(Ⅵ) under visible light irradiation(λ≥420 nm)within 2.5 h,which is significantly better than those of pure g-C_(3)N_(4) and CeO_(2).This work provides a new idea for more rationally designing and constructing g-C_(3)N_(4)-based catalysts for efficient extended photochemical application.Yanan Liu Zhangfeng Shen Jialing Song Huilan Qi Chaochuang Yin Xuhui Zou Qineng Xia Lifeng Cui Xi Li Yangang Wang 2020Chinese Chemical Letters2020,31,10:1
8In/ex-situ Raman spectra combined with EIS for observing interface reactions between Ni-rich layered oxide cathode and sulfide electrolyte显示文摘The interfacial instability between Ni-rich layered oxide cathodes and sulfide electrolytes is a serious problem,leading to poor electrochemical properties of all-solid-state lithium batteries(ASSLB).The chemical/electrochemical side reactions are considered to be the origin of the interfacial deterioration.However,the influence of chemical and electrochemical side reactions on the interfacial deterioration is rarely studied specifically.In this work,the deterioration mechanism of the interface between LiNi0.85-xCo0.15AlxO2 and Li10GeP2S12 is investigated in detail by combining in/ex-situ Raman spectra and Electrochemical Impedance Spectroscopy(EIS).It can be determined that chemical side reaction between LiNi0.8Co0.15Al0.05O2 and Li10GeP2S12 will occur immediately once contacted,and the interfacial deterioration becomes more serious after charge-discharge process under the dual effects of chemical and electrochemical side reactions.Moreover,our research reveals that the interfacial stability and the cycle performance of ASSLB can be greatly enhanced by increasing Al-substitution for Ni in LiNi0.85-xCo0.15AlxO2.In particular,the capacity retention of LiNi0.6Co0.15Al0.25O2 cathode after 200 cycles can reach 81.9%,much higher than that of LiNi0.8Co0.15Al0.05O2 cathode(12.5%@200 cycles).This work gives an insight to study the interfacial issues between Ni-rich layered oxide cathode and sulfide electrolyte for ASSLBs.Xuelei Li Huilan Guan Zhijie Ma Ming Liang Dawei Song Hongzhou Zhang Xixi Shi Chunliang Li Lifang Jiao Lianqi Zhang 2020Journal of Energy Chemistry2020,29,9:1
9Mechanical performance analysis and stiffness test of a new type of suspension bridge显示文摘A new type of suspension bridge is proposed based on the gravity stiffness principle.Compared with a conventional suspension bridge,the proposed bridge adds rigid webs and cross braces.The rigid webs connect the main cable and main girder to form a truss that can improve the bending stiffness of the bridge.The cross braces connect the main cables to form a closed space truss structure that can improve the torsional stiffness of the bridge.The rigid webs and cross braces are installed after the construction of a conventional suspension bridge is completed to resist different loads with different structural forms.A new type of railway suspension bridge with a span of 340 m and a highway suspension bridge with a span of 1020 m were designed and analysed using the finite element method.The stress,deflection of the girders,unbalanced forces of the main towers,and natural frequencies were compared with those of conventional suspension bridges.A stiffness test was carried out on the new type of suspension bridge with a small span,and the results were compared with those for a conventional bridge.The results showed that the new suspension bridge had a better performance than the conventional suspension bridge.Xia QIN Mingzhe LIANG Xiaoli XIE Huilan SONG 2021Frontiers of Structural and Civil Engineering2021,15,5:1
10Ralstonia solanacearum type Ⅲ effector RipAS associates with potato type one protein phosphatase StTOPP6 to promote bacterial wilt显示文摘The bacterial pathogen Ralstonia solanacearum(R.solanacearum)delivered type III secretion effectors to inhibit the immune system and cause bacterial wilt on potato.Protein phosphatases are key regulators in plant immunity,which pathogens can manipulate to alter host processes.Here,we show that a type III effector RipAS can reduce the nucleolar accumulation of a type one protein phosphatase(PP1)StTOPP6 to promote bacterial wilt.StTOPP6 was used as bait in the Yeast two-Hybrid(Y2H)assay and acquired an effector RipAS that interacts with it.RipAS was characterized as a virulence effector to contribute to R.solanacearum infection,and stable expression of RipAS in potato impaired plant resistance against R.solanacearum.Overexpression of StTOPP6 showed enhanced disease symptoms when inoculated with wild strain UW551 but not the ripAS deletion mutant,indicating that the expression of StTOPP6 facilitates the virulence of RipAS.RipAS reduced the nucleolar accumulation of StTOPP6,which occurred during R.solanacearum infection.Moreover,the association also widely existed between other PP1s and RipAS.We argue that RipAS is a virulence effector associated with PP1s to promote bacterial wilt.Bingsen Wang Wenfeng He Mengshu Huang Jiachen Feng Yanping Li Liu Yu Yuqi Wang Dan Zhou Chengzhen Meng Dong Cheng Ning Tang Botao Song Huilan Chen 2023Horticulture Research2023,10,6:0
11CD19-targeted chimeric antigen receptor-modified T cells induce remission in patients with relapsed acute B lymphoblastic leukemia after umbilical cord blood transplantation显示文摘To the Editor:Umbilical cord blood transplant(UCBT)serves as an alternative option for treating patients with B cell acute lymphoblastic leukemia(ALL),in the absence of a compatible donor.However,disease recurrence presents a difficult challenge.Chimeric antigen receptor(CAR)-T cell therapy is a promising approach for treating patients with relapsed/refractory ALL.Among the intensive investigations of infusion of CAR-T cells after transplant,few focus on patients who were administered CAR-T therapy after they relapsed subsequently to UCBT.Here,we report the response rate,toxicity,and survival of CD19 CAR-T cells administered to 10 children and young adults with relapsed acute B lymphoblastic leukemia(B-ALL)after UCBT.Between April 2018 and September 2019,11 patients with relapsed B-ALL after UCBT were enrolled,including three females and eight males,the median age was 10 years(range 7-22 years)and median weight was 35.0 kg(range 21.0-72.0 kg).Patient 10 was excluded because of unsuccessful cell culture.Qianwen Xu Hui Xu Lei Xue Min Wang Guiwang Pan Xuhan Zhang Kaidi Song Wen Yao Xiang Wan Juan Tong Huilan Liu Hanying Xu Xin Liu Xiaoyu Zhu Zimin Sun Lin Yang Xingbing Wang 2022Chinese Medical Journal2022,,1:0
