| 1 | EFFECT OF CHROMIUM AND BORON ON ENVIRONMENTAL EMBRITTLEMENT OF FORGED Fe_3Al显示文摘The effects of addition of chromium or boron on room temperature tensile properties,fracture behavior and susceptibility to test environments (air vs. vacuuwi of forged Fe3Al have been investigated. The results indicated that both chromium and boron result in increasing room temperuture ductility and fracture strength of the Fe3Al alloy whether tested in air or in vacuum. The susceptibility to test envimnment was described with the embrittlement index I: I=(δv-δA)/δv. The embrittlement indexes, for Fe-30Al, Fe-30Al-4Cr and Fe-30Al-0. 13B (at. %), are 24%, 37% and 29%,respectively. Scanning electron microscope examination of fracture surface revealed that the fracture mode of the three alloys remains unchanged, and all of them exhibited a transgranular cleavage fracture mode when tested in vacuum or air. | J.Q.

| 2 | 比较胺碘酮加β受体阻断剂、单用索他洛尔与单用β受体阻断剂预防埋藏式复律除颤器电击的随机试验:OPTIC研究显示文摘Context: Implantable cardioverter defibrillator(ICD) therapy is effective but is associated with high-voltage shocks that are painful. Objective: To determine whether amiodarone plus β -blocker or sotalol are better than β -blocker alone for prevention of ICD shocks. Design, Setting, and Patients: A randomized controlled trial with blinded adjudication of events of 412 patients from 39 outpatient ICD clinical centers located in Canada, Germany, United States, England, Sweden, and Austria, conducted from January 13, 2001, to September 28, 2004. Patients were eligible if they had received an ICD within 21 days for inducible or spontaneously occurring ventricular tachycardia or fibrillation. Intervention: Patients were randomized to treatment for 1 year with amiodarone plus β -blocker, sotalol alone, or β -blocker alone. Main Outcome Measure: Primary outcome was ICD shock for any reason. Results: Shocks occurred in 41 patients(38.5% ) assigned to β -blocker alone, 26(24.3% ) assigned to sotalol, and 12(10.3% ) assigned to amiodarone plus β -blocker. A reduction in the risk of shock was observed with use of either amiodarone plus β -blocker or sotalol vs β -blocker alone(hazard ratio[HR], 0.44; 95% confidence interval[CI], 0.28- 0.68; P< .001). Amiodarone plus β -blocker significantly reduced the risk of shock compared with β -blocker alone(HR, 0.27; 95% CI, 0.14- 0.52; P< .001) and sotalol(HR, 0.43; 95% CI, 0.22- 0.85; P=.02). There was a trend for sotalol to reduce shocks compared with β -blocker alone(HR, 0.61; 95% CI, 0.37- 1.01; P=.055). The rates of study drug discontinuation at 1 year were 18.2% for amiodarone, 23.5% for sotalol, and 5.3% for β -blocker alone. Adverse pulmonary and thyroid events and symptomatic bradycardia were more common among patients randomized to amiodarone. Conclusions: Despite use of advanced ICD technology and treatment with a β -blocker, shocks occur commonly in the first year after ICD implant. Amiodarone plus β -blocker is effective for preventing these shocks and is more effective than sotalol but has an increased risk of drug-related adverse effects.
