5,6,7-Trihydroquinolin-8-one was condensed with the corresponding benzidine to give N,N′-bis（5,6,7-trihydroquinolin-8-ylidene）-[1,1′-biphenyl]-4,4′-diamine derivatives（L1–L3）. The ligands were reacted with two equivalents of Ni Cl2·6H2O in a mixture of Et OH and CH2Cl2 to afford the corresponding dinickel（II） chloride complexes（Ni1-Ni3）. The organic compounds were completely characterized, whilst the bi-metallic complexes were characterized by FTIR spectra and elemental analysis. These nickel complexes exhibited high activities towards ethylene polymerization in the presence of either MAO or Me2AlCl, maintaining a high activity over a prolonged period. The obtained polyethylenes were confirmed as having low molecular weights by GPC analysis.

模拟隧道窑内燃方式制备烧结保温砌块,研究了造纸污泥的热解特性,并与煤矸石进行了对比研究。结果表明,造纸污泥105℃烘干后的热值为2157J/g,当焙烧温度上升到500℃时,造纸污泥的残余热值就为0,同时达到最大烧失量51%,而煤矸石的残余热值到1000℃才释放完,其最大烧失量为19%。造纸污泥的热解特性与煤矸石不同,造纸污泥的可燃物质在以隧道窑内燃为主要焙烧方式的烧结工艺中难以有效利用。

目的:探讨生姜对华法林抗凝作用的影响、作用机制和处理方法。方法与结果:病例回顾:1例62岁的患者长期服用华法林并稳定维持剂量,开始每日合并9g生姜1月后查INR值升至4.41,就诊抗凝门诊后停用生姜,后根据INR值逐步调整华法林剂量至原来水平;另1例70岁患者长期服用稳定维持剂量的华法林抗凝治疗,食用醋泡姜1周后INR升至4.59,停用醋泡姜后逐渐调整华法林剂量至原来水平。结论:生姜与华法林相互作用机制尚不明确,本研究与文献回顾显示华法林与生姜相互作用为"很可能"。当长期服用华法林的患者需要生姜补充替代治疗时,推荐抗凝门诊药师根据食用生姜的量和疗程判断可能发生相互作用的严重程度,加强监测INR值,必要时调整华法林剂量,从而为临床实践提供指导。
