This study compared the safety and efficacy of cilostazol and clopidogrel after coronary stenting. Patients(n=689) w.o underw.nt successful stenting w.re randomly assigned to receive cilostazol(group 1, n=344, 612 lesions) or clopidogrel(group 2, n=345, 628 lesions). The incidence of subacute stent thrombosis or major adverse cardiac events, including death, myocardial infarction, and target lesion revascularization w.thin 30 days(2.6%in group 1 vs 2.0%in group 2, p=0.61) and side effects that required cessation of study drug(0.6%each) did not differ statistically betw.en groups. These results indicate that cilostazol is as safe and effective as clopidogrel in preventing thrombotic complications after stenting.

贝特类药在“他汀类药不良HDL-C反应者”治疗中的益处

Low.ring high levels of low.density lipoprotein cholesterol(LDL-C) is the primary aim in the prevention of cardiac events. How.ver, low.levels of high-density lipoprotein cholesterol(HDL-C) are also associated w.th an increased risk of ischemic heart disease. Some patients have low.r HDL-C during statin treatment than before the treatment. These patients w.re first described in 2002 as ‘ bad HDL-C responders to statins’ . The aim of this study w.s to describe the benefit of fibrates in monotherapy for these patients. Methods: A cross-sectional survey of lipid levels, cardiovascular disease and risk factors in outpatients treated for dyslipidemia. For this study w. analyzed the lipid levels, drug treatment and medical history for 14 patients w.th low.HDL-C(w.th fibrates. Results: Total cholesterol(TC) and LDL-C w.re respectively 8% and 6% higher w.th fibrates compared to statins. Mean HDL-C w.s 49% higher during fibrate treatment and TC to HDL-C and LDL-C to HDL-C w.re respectively 26% and 27% low.r w.th fibrates. Conclusions: Patients w.th low.levels of HDL-C during statin treatment had far better levels for HDL-C, TC to HDL-C and LDL-C to HDL-C w.th fibrates in monotherapy. For bad HDL-C responders to statins w.th low.or normal LDL-C treatment w.th fibrates instead of statins should be considered. For those w.th high LDL-C fibrates should be added to statins. A randomized double-blind crossover trial w.th simvastatin and fenofibrate has been initiated to corroborate these findings.

众所周知,无论个人条件如何,没有人能仅凭天赋充任一名称职的警官。刑事侦察工作尤其如此。因为这种警察业务需要各种各样的技能、知识和能力。为此,警界一向强调刑侦人员必须经过培养,使其具有耐心、自我修养、细致观察、熟知法律和社会交往的能力,以及对科学方法的掌握和对各种技术的了解,尤其应有很强的决策能力,运用归纳推理和演绎推理解决实际问题的能力。
