采用激光熔覆工艺参数,对轧辊表面裂纹使用Fe基金属粉末涂层修复,再对涂层进行力学性能测试,探索出最优工艺参数。在不同工艺参数下制备涂层,切取所需试验样品。采用X射线衍射(XRD)分析Fe基金属激光熔覆试样的物相组成。用金相显微镜分析了Fe基金属激光熔覆试样的显微组织结构,用扫描电镜(SEM)分析了Fe基金属激光熔覆试样的晶体结构。用显微硬度仪测试了Fe基金属激光熔覆试样的维氏显微硬度。用高速摩擦试验机对Fe基金属激光熔覆试样进行耐摩擦测试。结果表明:涂层组织均且致密,所有涂层表面都没有裂纹和气孔,物相基本以(Fe,Ni)为主,硬度在260~428 HV0.2,涂层的摩擦系数在0.6左右,磨损率都在10^(-5)这个数量级。Fe基金属粉末激光熔覆涂层拥有良好力学性能,能很好的修复轧辊的同时还可延长使用寿命。2000 W激光功率和扫描速度10 mm/s是最佳熔覆参数。

我国部分道路污染水平与国外污染水平相差较小。但华南、华东区域与华北、华中区域差异明显,其中以上海、深圳、天津等城市污染最为严重,这与城市发展水平、人口数量、气候等相关。目前水体多环芳烃污染降解研究热点可分为生物与非生物技术。最新研究多集中于微生物降解多环芳烃,其中以筛选微生物菌株和微生物刺激研究为主。微生物修复效果与适用性远超植物修复、物理化学修复。但未来研究热点更倾向于微生物联合植物、微生物联合微生物、微生物联合物理材料等方向。通过收集国内外道路多环芳烃污染相关研究数据,梳理了部分城市道路多环芳烃污染负荷、来源、特征及其分布情况,总结了目前水体多环芳烃治理技术与雨水径流治理设施适用性,旨在为今后我国道路多环芳烃污染治理提供参考。

目的:基于扎根理论的探索性研究方法构建老年痴呆病人家庭照顾者内疚感下游效应维度的理论模型。方法:于2023年3月—5月,采用目的抽样和理论抽样的方法从十堰市4所三级甲等医院和4个社区中选取36名老年痴呆病人的家庭照顾者作为研究对象,进行半结构化深度访谈。运用程序化扎根理论的研究方法,辅以NVIVO 12.0软件,对获取的原始数据进行开放式编码、主轴编码及选择性编码,并开展理论饱和度检验。结果:分析发现,心理健康、生理健康、照顾质量、生活质量、社交关系是家庭照顾者内疚感下游效应维度的5个主要范畴。其中,心理健康被视为核心维度,而生理健康、照顾质量、生活质量和社交关系分别被视为基础维度、中心维度、保障维度和外部维度。结论:本研究形成了老年痴呆病人家庭照顾者内疚感下游效应维度的理论模型,即“心理-生理-照顾-生活-社交”五维理论模型。

目的分析供者特异性HLA抗体(anti-HLA donor-specific antibodies, DSA)及DSA阳性患者的去敏治疗对单倍体造血干细胞移植(haploidentical hematopoietic stem cell transplantation, haplo-HSCT)植入效果的影响。方法收集2017年3月至2023年7月重庆医科大学附属第二医院血液内科行haplo-HSCT,并完成HLA抗体及DSA检测的患者70例,分析DSA阳性和DSA阳性患者去敏治疗对造血干细胞移植植入效果的影响。结果 70例haplo-HSCT患者完成抗体检测,DSA阳性患者15例(21.4%),其中7例(46.7%)强阳性,3例(20.0%)中度阳性,5例(33.3%)弱阳性。DSA阳性患者移植后粒系植入中位时间较DSA阴性患者明显延迟(P=0.027)。植入失败(graft failure, GF)患者6例,DSA阳性4例(26.7%),明显高于DSA阴性(P=0.025)。多因素分析结果显示,DSA是发生GF的独立影响因素(HR=9.273, 95%CI=1.505~57.124,P=0.016)。10例DSA中度和强阳性患者进行去敏治疗,4例采用联合去敏治疗,患者均成功植入(100.0%),6例采用单一去敏治疗,有4例(66.7%)发生GF,联合去敏治疗的GF发生率显著低于单一去敏治疗(P=0.008)。结论 DSA是导致haplo-HSCT患者植入延迟和GF的重要因素,对DSA中度及强阳性患者的单一去敏治疗效果有限,而多联合的去敏治疗时,动态监测抗体滴度水平下降,可保证干细胞的成功植入,降低GF发生。
