摘要：本文全面阐述了德国铁路新开发的第三代ＩＣＥ城间高速列车－ＩＣＥ２．２的设计要求与全新概念，其中包括：车体结构与内装修设计，走行部分与牵引设备等。该列车首次采取动力分散式动车且，装有再生，线性涡流，盘形制动，并设有列车信息和故障诊断系统。列车构造速度３３０ｋｍ／ｈ，最高运行速度３００ｋｍ／ｈ，将成为德国技术水平先进、档次最高的高速列车，拟用于德国１９９８年后的国内和欧洲高速铁路网高速客运。

摘要：The peroxisome proliferator-activated receptors （PPaRs）, PPaRt,, PPaRβ/δ and PPaRy, are ligand-activated transcriptional factors, which belong to the nuclear receptor super family and play crucial roles in glucose and lipid metabolism. Based on the impressive advantages ofPPaR agonists （like TZD and fibrate compounds） in the treatment of metabolic syndrome and type 2 diebetes, PPaR modulators have doubtlessly grabbed much more attention. However, serious clinical adverse effects, especially for PPaRy agonists, hinder the development of PPaR agonist, Therefore, the selectivity and safety would be the key points and have been taken into the consideration for novel generation PPaR agonist research, and then several dual- or pan-PPaR modulators have emerged. Furthermore, experimental study indicates that partial agonists can neutralize the side effect and achieve modest therapeutic effect. This review summa.ies structural features of PPaR receptors, illustrates the method of PPaR modulator design, then lists and analyzes recent dual- and nan- agonists

摘要：＂avocado sadness＂ caused by the Oomycete Phytophthora cinnamomi Rands, is one of the ma.n diseases affecting this fruit crop in Michoacan, M6xico, without having an efficient control strategy for that. In this research three Trichoderma.isolates and Ridomil Gold 4E fungicide were tested in avocado trees infected with this pathogen using the growing and coloring vegetative flow growing. Results were analyzed with an experimental design completely random with four treatments and repetitions. Different responses were presented form avocado trees to each treatment. Trichoderma.erinaceum Bissett, Kubicek ＆ Szackacs treatment was the best controlling disease in trees with grade II and III dama.e. Trichoderma.aggressivum Samuels ＆ W. Gams controlled better in trees with grade III dama.e. at last, Trichoderma.arundinaceum Zafari, Graef. and Samuels were the best controlling trees with the highest grade dama.e. Fungicide Ridomil Gold 4E controlled the disease in trees with the lowest grade dama.e （I and II）, their medias were similar to witness.

摘要：设计：半随机对照试验。干预措施：乳磨牙用传统活髓切断术治疗，但随机分配至以MTa或FC为牙髓敷料组。每6个月进行临床（非盲）和X线片（盲法）检查。结局指标：随访至活髓切断术失败、牙自然脱落和患者失访。活髓切断术成功率=（活髓切断术不失败牙数／总治疗牙数）×100结果：最终有62例活髓切断术牙进入分析，其中29例为FC组，33例为MTa组。平均随访16个月（4～30个月）时，共计6例治疗失败，其中1例为MTa组，5例为FC组。活髓切断术成功率MTa组为97％，FC组为83％。在平均随访38个月（4～74个月）时，试验组和对照组间无统计学差异。结论：在乳磨牙活髓切断术中，应用MTa或FC对治疗成功率无统计学差异。
