| 1 | 纳米SiO_2/聚丙烯复合材料的微观结构显示文摘利用原子力显微镜和透射电镜分析了聚苯乙烯辐射接枝纳米二氧化硅粒子(SiO2-g-PS)填充聚丙烯(PP)的微观结构,并与该复合材料的拉伸和冲击强度相关联,为探讨纳米粒子的增强增韧作用机制提供了直观证据。利用原子力显微镜进行的微划痕和纳米压痕实验,通过与显微硬度和动态力学性能测试结果的比较,证实了接枝改性后的纳米粒子团聚体具有承载能力,而这些团聚体对复合材料的局部和整体力学响应不同,揭示了团聚体增强效应的内在原因,即在纳米粒子团聚体内部以及团聚体之间形成了特定的应力双逾渗结构。 | FRIEDRICH Klaus SREEKALA Meyyarappallil Sadasivan LEHMANN Bjoern 容敏智 章明秋 | 2006 | 复合材料学报2006，23，1： | 9 |
| 2 | Standard triple versus levofloxacin based regimen for eradication ofHelicobacter pylori显示文摘AIM:To compare the eradication rates for Helicobacter pylori(H.pylori) and ulcer recurrence of standard triple therapy(STT) and levofloxacin based therapy(LBT).METHODS:Seventy-four patients with perforated duodenal ulcer treated with simple closure and found to be H.pylori infected on 3 mo follow up were randomized to receive either the STT group comprising of amoxicillin 1 g bid,clarithromycin 500 mg bid and omeprazole 20 mg bid or the LBT group comprising of amoxicillin 1 g bid,levofloxacin 500 mg bid and omeprazole 20 mg bid for 10 d each.The H.pylori eradication rates,side effects,compliance and the recurrence of ulcer were assessed in the two groups at 3 mo follow up.RESULTS:Thirty-four patients in the STT group and 32 patients in the levofloxacin group presented at 3 mo follow up.H.pylori eradication rates were similar with STT and the LBT groups on intention-to-treat(ITT) analysis(69% vs 80%,P = 0.425) and(79% vs 87%,P = 0.513) by per-protocol(PP) analysis respectively.Ulcer recurrence in the STT and LBT groups on ITT analysis was(20% vs 14%,P = 0.551) and(9% vs 6%,P = 1.00) by PP analysis.Compliance and side effects were also comparable between the groups.A complete course of STT costs Indian Rupees(INR) 1060.00,while LBT costs only INR 360.00.CONCLUSION:H.pylori eradication rates and the rate of ulcer recurrence were similar between the STT and LBT.The LBT is a more economical option compared to STT. | Raj Gopal Thirthar Palanivelu Elamurugan Vikram Kate Sadasivan Jagdish Debdatta Basu | 2013 | World Journal of Gastrointestinal Pharmacology and Therapeutics2013，4，2： | 2 |
