| 1 | Transplantation of human umbilical cord blood mesenchymal stem cells to treat a rat model of traumatic brain injury显示文摘In the present study, human umbilical cord blood mesenchymal stem cells were injected into a rat model of traumatic brain injury via the tail vein. Results showed that 5-bromodeoxyuridine-labeled cells aggregated around the injury site, surviving up to 4 weeks post-transplantation. In addition, transplantation-related death did not occur, and neurological functions significantly improved. Histological detection revealed attenuated pathological injury in rat brain tissues following human umbilical cord blood mesenchymal stem cell transplantation. In addition, the number of apoptotic cells decreased. Immunohistochemistry and in situ hybridization showed increased expression of brain-derived neurotrophic factor, nerve growth factor, basic fibroblast growth factor, and vascular endothelial growth factor, along with increased microvessel density in surrounding areas of brain injury. Results demonstrated migration of transplanted human umbilical cord blood mesenchymal stem cells into the lesioned boundary zone of rats, as well as increased angiogenesis and expression of related neurotrophic factors in the lesioned boundary zone. | Junjian Zhao Naiyao Chen Na Shen Hui Zhao Dali Wang Jun Shi Yang Wang Xiufeng Cui Zhenyu Yan Hui Xue | 2012 | Neural Regeneration Research2012，7，10： | 5 |

| 5 | Stress response to nanoplastics with different charges in Brassica napus L.during seed germination and seedling growth stages显示文摘Nanoplastic pollution has become a significant problem in farmland systems worldwide.However,research on the effects of nanoplastics(NPs)with different charges on field crops is still limited.In our study,NPs with different charges,including unmodified polystyrene nanoplastics(PS),positively charged polystyrene nanoplastics(PS-NH_(2)),and negatively charged polystyrene nanoplastics(PSSO3H),were investigated for their impacts on seed germination and seedling growth of rape.The results showed that seed water uptake(after 12 h),seed germination,seed vigour,and relative root elongation were all significantly reduced under exposure to NPs(200 mg/L).Similarly,remarkable decreases in plant biomass(root weight,shoot weight),growth(root length,plant height),photosynthesis ability(chlorophyll a,chlorophyll b,carotenoids),essential nutrient uptake(Fe,Mn,Zn,Cu),and plant quality(soluble protein,soluble sugar,crude fibre content)of rape seedlings were also observed after exposure to NPs.Among the three kinds of NPs,PS-NH_(2)showed stronger effects.Moreover,superoxide dismutase,peroxidase,and catalase activities of rape seedlings were changed,and the content of malondialdehyde was significantly increased under exposure to NPs.Furthermore,positively charged PS-NH_(2)showed stronger effects on the phenotype,physiology,biochemistry,nutrient uptake,and plant quality of rape.Notably,a comprehensive toxicity evaluation revealed that PS-NH_(2)had the strongest toxicity to rape.The present study provides important implications for the interaction and risk assessment of NPs and crops in soil-plant systems. | Tao Li Xiufeng Cao Rui Zhao Zhaojie Cui | 2023 | Frontiers of Environmental Science & Engineering2023，17，4： | 1 |

| 7 | Two-stage seedling cultivation method for sweet peppers combining closed plant factory and solar greenhouse显示文摘This study introduced a two-stage cultivation method for sweet pepper seedlings, integrating the strengths of a closed plant factory and solar greenhouse, to mitigate the environmental constraints in Northeast China during the early spring season. In the first stage, seedlings were cultivated in a closed plant factory, followed by a second stage in a solar greenhouse. Four treatments- T1 (9 and 36 d), T2 (12 and 33 d), T3 (15 and 30 d), and T4 (18 and 27 d) - were designed for the first and second stages, respectively, with solar greenhouse-only approach serving as the control (CK). The findings reveal that the two-stage methodology significantly outperformed the control across multiple metrics, including seedling health index, chlorophyll content, photosynthetic capacity, yield, etc. Specifically, T3 emerged as optimal, boosting the health index by 38.59%, elevating chlorophyll content by 39.61%, increasing net photosynthesis by 34.61%, and augmenting yield per plant by 40.67%. Additionally, T3 expedited the time to harvest by 25 d compared to the control. Although the seedling cost for T3 was 0.12 RMB yuan higher, the benefits offset the additional investment. In conclusion, the two-stage cultivation method effectively leverages the advantages of both closed-plant factories and solar greenhouses, resulting in superior seedling quality compared to using only solar greenhouses. It offers a practical and economically viable solution for enhancing the quality and yield of sweet pepper seedlings, thus contributing to the progress in the field of facility seedling cultivation research. | Hongbo Cui Fang Ji Yanni Liu Zhengyang Luo Xiufeng Wang Jianfeng Wang | 2023 | International Journal of Agricultural and Biological Engineering2023，16，6： | 0 |
| 8 | Field-free approaches for deterministic spin–orbit torque switching of the perpendicular magnet显示文摘All-electrical driven magnetization switching attracts much attention in next-generation spintronic memory and logic devices,particularly in magnetic random-access memory(MRAM)based on the spin–orbit torque(SOT),i.e.SOT-MRAM,due to its advantages of low power consumption,fast write/read speed,and improved endurance,etc.For conventional SOT-driven switching of the magnet with perpendicular magnetic anisotropy,an external assisted magnetic field is necessary to break the inversion symmetry of the magnet,which not only induces the additional power consumption but also makes the circuit more complicated.Over the last decade,significant effort has been devoted to field-free magnetization manipulation by using SOT.In this review,we introduce the basic concepts of SOT.After that,we mainly focus on several approaches to realize the field-free deterministic SOT switching of the perpendicular magnet.The mechanisms mainly include mirror symmetry breaking,chiral symmetry breaking,exchange bias,and interlayer exchange coupling.Furthermore,we show the recent progress in the study of SOT with unconventional origin and symmetry.The final section is devoted to the industrial-level approach for potential applications of field-free SOT switching in SOT-MRAM technology. | Hao Wu Jing Zhang Baoshan Cui Seyed Armin Razavi Xiaoyu Che Quanjun Pan Di Wu Guoqiang Yu Xiufeng Han Kang L Wang | 2022 | Materials Futures2022，1，2： | 0 |
| 9 | Development and commercial application of Baosteel sintering flue gas recirculating process显示文摘Because of the low temperature,large waste gas volume,high pollutant content,and complicated compositions,waste heat recovery and emission gas treatment of sintering flue gas have always presented a challenge in the steel industry,and this issue has attracted widespread attention both locally and abroad. Recently,based on the first domestic pilot plant and demonstration project,Baosteel has performed a series of innovative research and development investigations on its sintering flue gas recirculating( SFGR) process,in which the system design and optimization,dioxin-related contaminant source suppression,ore matching structure optimization,wear-resistant design of cycling fans and pipelines,high-efficiency dust removal equipment,system control and stable operation strategy,flue gas mixing and switching control,circular hood sealing,oxygen content conditioning,recirculation sintering system process control,and model development have been studied,and a complete set of equipment and technology for the SFGR process has been initially developed. The investigation results suggest that the SFGR process can not only significantly reduce exhaust gas volume and pollutant emissions but also recover low-temperature waste heat and reduce the energy consumption of sintering; therefore,the overall technologies possess great value in energy savings,pollution emission reduction,and sintering ore quality / yield improvement. | CUI Jian LI Xianwei SHI Lei DU Hongjin JIA Xiufeng XI Saifeng YU Bo WANG Ruyi YU Yongmei JIN Chun YANG Yun | 2014 | Baosteel Technical Research2014，8，4： | 0 |
