在突发水污染应急处置过程中,纤维状吸附材料形态自由度大,应用灵活且便于回收,但现有的纤维状材料制备时间较长,严重限制其在实际中的应用.为此,以价廉易得的黄麻为基体,采用微波辅助对其进行快速预处理和接枝改性.在单因素实验的基础上,采用响应曲面法对黄麻预处理工艺的参数进行优化,并与高温碱煮法进行对比;而后在预处理黄麻上接枝羧基,通过对微波辅助与水浴加热法下的接枝反应速率进行比较,揭示微波在接枝反应中的作用;最后,考察改性黄麻对水中重金属离子的吸附效果.结果表明,与高温碱煮工艺相比,微波辅助碱预处理工艺缩短了反应时间(缩短约70%),降低了碱液质量分数(由20%降至16%);微波辅助下的初始接枝反应速率约为水浴加热下的18.6倍.这是因为微波提高了接枝反应的指前因子,降低了表观活化能,促进了反应的发生.与原麻相比,改性黄麻对水中重金属离子的吸附效果有明显提高.

目的探讨梭形细胞型髓样甲状腺癌(MTC)临床病理学特征。方法收集2012至2019年空军军医大学(第四军医大学)西京医院诊断的梭形细胞型MTC 4例,分析其临床资料、病理学形态及免疫表型,并复习相关文献。结果患者男性2例,女性2例,年龄26~54岁,患者均以颈部肿块就诊,其中1例有淋巴结转移。组织学观察,瘤组织以梭形细胞成分为主,细胞呈束状或交织状排列,细胞核呈短梭形或长梭形,胞质丰富,核仁不明显,核分裂象少见,肿瘤组织有纤维血管间质分隔伴淀粉样变,与周围甲状腺组织边界较清。免疫组织化学显示,所有病例肿瘤细胞均为降钙素、嗜铬粒素A(CgA)、突触素、CD56、甲状腺转录因子1(TTF1)阳性,Ki-67阳性指数3%~10%,而其他定向分化标志物均阴性。随访7~84个月,4例均健在,未见复发。结论梭形细胞型MTC是一种少见MTC病理类型,诊断需要结合病理形态及免疫组织化学标记。

浮动抵押制度具有扩大抵押人担保能力、不影响抵押人正常经营等独特优势。由于我国动产浮动抵押制度存在着浮动抵押权的客体范围过窄、缺乏接管人制度等设计上的不足,致使浮动抵押制度优势难以发挥。为此,文章提出应适当扩大设押财产范围、并对"正常经营活动"进行界定及合理限制、规定浮动抵押的接管人制度和健全社会信用体系等相应的完善措施,以实现浮动抵押制度在我国的有效运行。
