文摘Let K be a 1-unconditional convex bodies in Euclidean spaces.We study the asymptotic properties of two affine invariants m2(K) and S2(K) for a random simplex inside K.As an application,we discuss the asymptotic properties of two affine invariants m2(Bpn ) and S2(Bpn ),where Bpn = {x ∈ Rn : ‖x‖ p 1}.
文摘目的评价玉屏风散加减联合常规药物治疗单纯疱疹病毒性角膜炎的有效性和安全性。方法通过检索CENTRAL、Pub Med、EMbase、CBM、CNKI、中文科技期刊数据库(VIP)、万方数据库,并获取玉屏风散治疗单纯疱疹病毒性角膜炎的随机对照试验文献,在采用Cochrane偏倚风险评估工具对纳入研究进行方法学质量评估基础上,用Rev Man 5.3软件进行meta分析。结果 10个研究包括955例病例被纳入,meta分析结果表明,玉屏风散加减联合常规药物治疗的疗效优于单纯使用常规药物治疗,RR=1.12(95%CI:1.04,1.21);且复发率也低于常规药物治疗组,RR=0.21(95%CI:0.14,0.30);但倒漏斗图提示可能存在潜在的发表性偏倚。10个研究对不良事件或不良反应报告不充分。结论尽管玉屏风散加减联合常规药物治疗用于单纯疱疹病毒性角膜炎的疗效优于单用常规药物治疗,但所纳入研究的方法学质量较差,结论须谨慎应用。
