摘要:
Three-dimensional(3 D) graphene oxide-tris(4-aminophenyl)amine(GO-TAPAx:y) composites with different GO-to-TAPA mass ratios(x:y) were prepared by a facile one-step ultrasonic treatment.GOTAPAx:y composites were characterized by scanning electron microscopy(SEM),nitrogen(N2)adsorption-desorption isotherms,Fourier transform infrared spectroscopy(FTIR),X-ray photoelectron spectroscopy(XPS) and thermogravimetric analysis(TGA).Behavior and mechanism of GO-TAPAx:yco mposites for the adsorption of rare earth elements(REEs) were investigated.The adso rption capacities of GO-TAPA1;2 composite for Yb3+,Er3+,Nd3+,La3+and Y3+are 30.88,26.52,20.60,11.24 and 10.52 mg/g,respectively.Effects of some important parameters including GO-to-TAPA mass ratios,contact time,reaction temperature and initial Yb3+concentration on the adsorption were evaluated in detail.FTIR spectral and XPS analyses show that the metal complexations and ion exchanges between nitrogen/oxygen-containing species of the adsorbents and REEs are involved in the adsorption procedure besides the conventional adsorption based on specific surface area,indicating the introduction of specific molecules onto GO is beneficial to its adsorption ability.The convenient reusability and applicability of GO-TAPAx:y composites toward real samples also demonstrate their feasibility in the enrichment of REE ions.

摘要:
目的基于CiteSpace对治疗痉挛型脑瘫(spastic cerebral palsy,SCP)的中英文文献进行研究现状、研究热点及前沿的展示与分析,并进一步分析中西医治疗策略的差异,为创新SCP的诊治方案提供参考。方法利用Web of Science核心合集数据库和中国知网(CNKI)数据库检索建库至今发表的与SCP研究相关的文献,使用CiteSpace对发文量、共现网络和关键词进行可视化分析,并结合图谱内容解读其涵义。结果徐林和Gordon分别是治疗SCP相关中、英文文献发文量最高的作者,中医药特色期刊和高校发文量较高,但较国外起步时间晚、研究数量和合作频率低。主要研究内容是SCP的发病人群、临床分级分型、中药配伍和组方分析、中医药疗法、药物和手术治疗及其疗效考察等方面。中医治疗策略是运用针灸、推拿和中药辅助患者康复,西医治疗策略是通过外科手术和药物治疗SCP。结论中西医对SCP的治疗策略具较大差异,注重SCP早期干预和针灸推拿与诱导运动结合疗法研究是未来发展方向,应中西医结合创新发展和开发新的治疗方法。

摘要:
目的根据白术Atractylodis Macrocephalae Rhizoma指纹图谱形状特征,建立一种快速精准辨识不同产地与炮制品的方法。方法建立45批不同产地与炮制法的白术UPLC指纹图谱库,运用总量统计矩及相似度法、正交偏最小二乘-判别分析(orthogonal partial least squares-discriminant analysis,OPLS-DA)法辨析此指纹图谱的形状特点,捕获其特征指纹图谱及特征峰。结果生品、麸炒、土炒白术UPLC指纹图谱的共有峰16个;安徽与湖南、安徽与浙江、湖南与浙江产地的生白术的总量统计矩相似度分别为0.774~0.982、0.799~0.969、0.788~0.886;3产地的生品与麸炒、生品与土炒、麸炒与土炒白术的总量统计矩相似度中最大值为0.990, 最小值为0.774。再结合OPLS-DA法中变量重要性投影(variable importance for the projection,VIP)分析获得其中1~3、6、16号为区分贡献度最大的5个标志峰,确认6号峰为白术内酯II。结论这5个标志峰对应物质可认定白术的潜在质量标志物(Q-Marker),为白术的产地、炮制法的精准识别及其质量控制与评价提供理论与实验依据,同时也为中药指纹图谱辨形论质做了积极探索。
