| 1 | Application of regional citrate anticoagulation in patients at high risk of bleeding during intermittent hemodialysis:a prospective multicenter randomized controlled trial显示文摘Objective:Safe and effective anticoagulation is essential for hemodialysis patients who are at high risk of bleeding.The purpose of this trial is to evaluate the effectiveness and safety of two-stage regional citrate anticoagulation(RCA)combined with sequential anticoagulation and standard calcium-containing dialysate in intermittent hemodialysis(IHD)treatment.Methods:Patients at high risk of bleeding who underwent IHD from September 2019 to May 2021 were prospectively enrolled in 13 blood purification centers of nephrology departments,and were randomly divided into RCA group and saline flushing group.In the RCA group,0.04 g/mL sodium citrate was infused from the start of the dialysis line during blood draining and at the venous expansion chamber.The sodium citrate was stopped after 3 h of dialysis,which was changed to sequential dialysis without anticoagulant.The hazard ratios for coagulation were according to baseline.Results:A total of 159 patients and 208 sessions were enrolled,including RCA group(80 patients,110 sessions)and saline flushing group(79 patients,98 sessions).The incidence of severe coagulation events of extracorporeal circulation in the RCA group was significantly lower than that in the saline flushing group(3.64%vs.20.41%,P<0.001).The survival time of the filter pipeline in the RCA group was significantly longer than that in the saline flushing group((238.34±9.33)min vs.(221.73±34.10)min,P<0.001).The urea clearance index(Kt/V)in the RCA group was similar to that in the saline flushing group with no statistically significant difference(1.12±0.34 vs.1.08±0.34,P=0.41).Conclusions:Compared with saline flushing,the two-stage RCA combined with a sequential anticoagulation strategy significantly reduced extracorporeal circulation clotting events and prolonged the dialysis time without serious adverse events. | Xiaoyan TANG Dezheng CHEN Ling ZHANG Ping FU Yanxia CHEN Zhou XIAO Xiangcheng XIAO Weisheng PENG Li CHENG Yanmin ZHANG Hongbo LI Kehui LI Bizhen GOU Xin WU Qian YU Lijun JIAN Zaizhi ZHU Yu WEN Cheng LIU Hen XUE Hongyu ZHANG Xin HE Bin YAN Liping ZHONG Bin HUANG Mingying MAO | 2022 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2022，23，11： | 4 |

| 3 | One-pot Synthesis of Hierarchical Flower-like WS_(2) Microspheres as Anode Materials for Lithium-ion Batteries显示文摘3D hierarchical flowerlike WS_(2) microspheres were synthesized through a facile one-pot hydrothermal route.The as-synthesized samples were characterized by powder X-ray powder diffraction (XRD),energy-dispersive spectroscopy (EDS),scanning electron microscopy (SEM) and Raman.SEM images of the samples reveal that the hierarchical flowerlike WS_(2) microspheres with diameters of about 3-5μm are composed of a number of curled nanosheets.Electrochemical tests such as charge/discharge,cyclic voltammetry,cycle life and rate performance were carried out on the WS_(2) sample.As an anode material for lithium-ion batteries,hierarchical flowerlike WS_(2) microspheres show excellent electrochemical performance.At a current density of100 mA·g^(-1),a high specific capacity of 647.8 mA·h·g^(-1) was achieved after 120 discharge/charge cycles.The excellent electrochemical performance of WS_(2) as an anode material for lithium-ion batteries can be attributed to its special 3D hierarchical structure. | 张向华 TAN Hen WANG Ze XUE Maoquan | 2024 | Journal of Wuhan University of Technology(Materials Science)2024，39，1： | 0 |
