1Prediction of recent bank retreat processes at typical sections in the Jingjiang Reach显示文摘The Jingjiang Reach is experiencing continuous channel degradation owing to operation of the Three Gorges Project(TGP)in2003.Significant retreat processes at composite riverbanks have occurred at local sites of this reach,which may influence the stability of the river regime and the effect of existing river training works.Therefore,bank retreat plays a key role in fluvial processes of the Jingjiang Reach,and it is necessary to predict the long-term processes of bank retreat at typical sections in the reach.In this study,various factors influencing bank retreat in the Jingjiang Reach are investigated,based on bank erosion processes at four sections and the corresponding flow and sediment conditions.It is discovered that fluvial erosion intensity is a dominant factor in controlling the processes of bank retreat in the reach,although other factors,such as bank soil properties,can also influence bank retreat.The bankfull width at a section with severe bank erosion since 2002 is defined as being equal to the sum of the bankfull width in 2002 and the accumulated bank retreat distance after 2002.The magnitude of the bankfull width can be expressed as an exponential function of the previous 5-year average fluvial erosion intensity during flood seasons.The accumulated distances of bank retreat at four sections over the period 2002–2012 are predicted using the proposed empirical relationships,with the calculated bank retreat processes agreeing well with observed data.XIA JunQiang ZONG QuanLi ZHANG Yi XU QuanXi LI XiaoJuan 2014Science China(Technological Sciences)2014,57,8:20
2Synthesis of sulfur doped C_(3)N_(4) with enhanced photocatalytic activity in molten salt显示文摘In this paper,sulfur doped g-C_(3)N_(4)(S-g-C_(3)N_(4))was successfully prepared at 500℃ for 3 h via a modified molten salt method using dicyandiamide as the main raw material,trithiocyanuric acid as the sulfur source and LiBreKCl as the reaction medium.The as-prepared SeCN5.0% sample(the mass ratio of trithiocyanuric acid to dicyandiamide was 5.0%)composed of irregular flakes showed a band gap of 1.83 eV,which was narrower than that(2.55 eV)of pristine g-C_(3)N_(4).The SeCN5.0% sample also exhibited an outstanding absorption capacity of visible light.Moreover,the photodegradation rate toward methylene blue and tetracycline were respectively 10 and 20 times as high as that of bulk g-C_(3)N_(4) prepared by conventional heating methods,confirming its superior photocatalytic performance.These results can be attributed to that the replacement of lattice nitrogen with sulfur atom tuned the electronic structure of g-C_(3)N_(4),improved the absorption of visible light,optimized the separation of photogenerated electron-hole pairs,and consequently enhanced the photocatalytic activity of g-C_(3)N_(4).Moreover,the trapping experiments implied that hole(ht)and superoxide radical($O2)were the main active species in the process of photodegradation.Keke Guan Junyi Li Wen Lei Honghong Wang Zhaoming Tong Quanli Jia Haijun Zhang Shaowei Zhang 2021Journal of Materiomics2021,7,5:2
3Culturing adequate CAR-T cells from less peripheral blood to treat B-cell malignancies显示文摘Objective:Chimeric antigen receptor-modified T(CAR-T)cells have shown impressive results against relapsed/refractory B cell malignancies.However,the traditional manufacture of CAR-T cells requires leukapheresis to isolate large amounts of peripheral blood T cells,thus making some patients ineligible for the procedure.Methods:We developed a simple method for CAR-T cell preparation requiring small volumes of peripheral blood.First,CD3+T cells isolated from 50 mL peripheral blood from patients(B-cell malignancies)were stimulated with immobilized anti-CD3/RetroNectin in 6-well plates and then transduced with CAR-expressing lentiviral vector.After 4 d,the T cells were transferred to culture bags for large-scale CAR-T cell expansion.In vitro and animal experiments were performed to evaluate the activity of the manufactured CAR-T cells.Finally,29 patients with B-cell acute lymphoblastic leukemia(B-ALL)and 9 patients with B-cell lymphoma were treated with the CAR-T cells.Results:The CAR-T cells were expanded to 1–3×10^(8) cells in 8–10 d and successfully killed B cell-derived malignant tumor cells in vitro and in vivo.For patients with B-ALL,the complete remission rate was 93%1 month after CAR-T cell infusion;after 12 months,the overall survival(OS)and leukemia-free survival rates were 69%and 31%,respectively.For patients with lymphoma,the objective response rate(including complete and partial remission)was 78%2 months after CAR-T cell infusion,and after 12 months,the OS and progression-free survival rates were 71%and 43%,respectively.Cytokine-release syndrome(CRS)occurred in 65.51%and 55.56%of patients with B-ALL and B-cell lymphoma,respectively;severe CRS developed in 20.69%of patients with B-ALL and in no patients with lymphoma.Conclusions:Our novel method can generate sufficient numbers of CAR-T cells for clinical use from 50–100 mL peripheral blood,thus providing an alternative means of CAR-T cell generation for patients ineligible for leukapheresis.Lu Han Jian Zhou Linlin Li Keshu Zhou Lingdi Zhao Xinghu Zhu Qingsong Yin Yufu Li Hongqin You Jishuai Zhang Yongping Song Quanli Gao 2021Cancer Biology & Medicine2021,18,4:2
4Angular distribution of terahertz emission from laser interactions with solid targets显示文摘Intense femtosecond laser-plasma interactions can produce high power terahertz radiations.In our experiment,the polished copper target was irradiated by a p-polarized laser with intensity of more than 1018 W/cm2 at an incident angle of 67.5 from the target normal.The THz energy from three dierent detection angles is measured.The maximum emission is found in the direction at an angle of 45 to the laser backward direction,which is more than one order of magnitude higher than in the other two directions.A simple theoretical model has been established to explain the measurements.DU Fei LI Chun ZHOU MuLin WANG WeiMin SU LuNing ZHENG Yi GE XuLei LI YuTong MA JingLong LIU XiaoLong ZHANG Lu SHENG ZhengMing CHEN LiMing LU Xin DONG QuanLi WANG ZhaoHua WEI ZhiYi ZHANG Jie 2012Science China(Information Sciences)2012,55,1:2
5Three-dimensional graphitic carbon sphere foams as sorbents for cleaning oil spills显示文摘Frequent offshore oil spill accidents, industrial oily sewage, and the indiscriminate disposal of urban oily sewage have caused seri- ous impacts on the human living environment and health. The traditional oil-water separation methods not only cause easily environmental secondary pollution but also a waste of limited resources. Therefore, in this work, three-dimensional (3D) graphitic carbon sphere (GCS) foams (collectively referred hereafter as 3D foams) with a 3D porous structure, pore size distribution of 25-200 μm, and high porosity of 62vol% were prepared for oil adsorption via gel casting using GCS as the starting materials. The results indicate that the water contact angle (WCA) of the as-prepared 3D foams is 130°. The contents of GCS greatly influenced the hydrophobicity, WCA, and microstructure of the as-prepared samples. The adsorption capacities of the as-prepared 3D foams for paraffin oil, vegetable oil, and vacuum pump oil were approximately 12-15 g/g, which were 10 times that of GCS powder. The as-prepared foams are desirable characteristics of a good sorbent and could be widely used in oil spill accidents.Saisai Li Haijun Zhang Longhao Dong Haipeng Liu Quanli Jia 2022International Journal of Minerals,Metallurgy and Materials2022,29,3:1

15Non-medical financial burden in tuberculosis care: a cross-sectional survey in rural China显示文摘Background:Treatment of tuberculosis(TB)in China is partially covered by national programs and health insurance schemes,though TB patients often face considerable medical expenditures.For some,especially those from poorer households,non-medical costs,such as transport,accommodation,and nutritional supplementation may be a substantial additional burden.In this article we aim to evaluate these non-medical costs induced by seeking TB care using data from a large scale cross-sectional survey.Methods:A total of 797 TB cases from three cities were randomly selected using a stratified cluster sampling design.Inpatient medical costs,outpatient medical costs,and direct non-medical costs related to TB treatment were collected using in-person interviews by trained interviewers.Mean and median non-medical costs for different sub-groups were calculated and compared using Kruskal-Wallis and Mann–Whitney U tests.Regression analysis was conducted to assess the influence of different patient characteristics on total non-medical cost.Results:The median non-medical cost was RMB 1429,with interquartile range RMB 424–2793.The median non-medical costs relating to inpatient treatment,outpatient treatment,and additional nutrition supplementation were RMB 540,91,and 900,respectively.Of the 797 cases,20%reported catastrophic expenditure on non-medical costs.Statistically significant differences were detected between different cities,age groups,geographical locations,inpatient/outpatient care,education levels and family income groups.Conclusions:Non-medical costs relating to TB treatment are a serious financial burden for many TB patients.Financial assistance that can limit this burden is urgently needed during the treatment period,especially for the poor.Qiang Li Weixi Jiang Quanli Wang Yuan Shen Jingyuan Gao Kaori D.Sato Qian Long Henry Lucas 2016Infectious Diseases of Poverty2016,5,1:1

17Pathogenic role of microRNAs in atherosclerotic ischemic stroke:Implications for diagnosis and therapy显示文摘Ischemic stroke resulting from atherosclerosis(particularly in the carotid artery)is one of the major subtypes of stroke and has a high incidence of death.Disordered lipid homeostasis,lipid deposition,local macrophage infiltration,smooth muscle cell proliferation,and plaque rupture are the main pathological processes of atherosclerotic ischemic stroke.Hepatocytes,macrophages,endothelial cells and vascular smooth muscle cells are the main cell types participating in these processes.By inhibiting the expression of the target genes in these cells,microRNAs play a key role in regulating lipid disorders and atherosclerotic ischemic stroke.In this article,we listed the microRNAs implicated in the pathology of atherosclerotic ischemic stroke and aimed to explain their pro-or antiatherosclerotic roles.Our article provides an update on the potential diagnostic use of miRNAs for detecting growing plaques and impending clinical events.Finally,we provide a perspective on the therapeutic use of local microRNA delivery and discuss the challenges for this potential therapy.Qidi Jiang Yiran Li Quanli Wu Li Huang Jiasheng Xu Qingfu Zeng 2022Genes & Diseases2022,9,3:1
