AIM: To investigate stepwise sedation for elderly patients with mild/moderate chronic obstructive pulmonary disease (COPD) during upper gastrointestinal (GI) endoscopy. METHODS: Eighty-six elderly patients with mild/moderate COPD and 82 elderly patients without COPD scheduled for upper GI endoscopy were randomly assigned to receive one of the following two sedation methods: stepwise sedation involving three-stage administration of propofol combined with midazolam [COPD with stepwise sedation (group Cs), and nonCOPD with stepwise sedation (group Ns)] or continuous sedation involving continuous administration of propofol combined with midazolam [COPD with continuous sedation (group Cc), and non-COPD with continuous sedation (group Nc)]. Saturation of peripheral oxygen (SpO 2 ), blood pressure, and pulse rate were monitored, and patient discomfort, adverse events, drugs dosage, and recovery time were recorded. RESULTS: All endoscopies were completed successfully. The occurrences of hypoxemia in groups Cs, Cc, Ns, and Nc were 4 (9.3%), 12 (27.9%), 3 (7.3%), and 5 (12.2%), respectively. The occurrence of hypoxemia in group Cs was significantly lower than that in group Cc (P < 0.05). The average decreases in value of SpO 2 , systolic blood pressure, and diastolic blood pressure in group Cs were significantly lower than those in group Cc. Additionally, propofol dosage and overall rate of adverse events in group Cs were lower than those in group Cc. Finally, the recovery time in group Cs was significantly shorter than that in group Cc, and that in group Ns was significantly shorter than that in group Nc (P < 0.001). CONCLUSION: The stepwise sedation method is effective and safer than the continuous sedation method for elderly patients with mild/moderate COPD during upper GI endoscopy.

受挡墙水泥土横向联系作用的影响,型钢水泥土搅拌墙(简称SMW工法)空间变形特性显著,由于难以量化挡墙的空间变形作用和水泥土承载能力,目前SMW工法的设计并未考虑挡墙空间变形作用和水泥土对挡墙的承载贡献。通过对悬臂式SMW工法挡墙的变形及受力进行分析,求解得到挡墙空间变形的各项应变能,根据应变能与抗力的关系,定义了空间变形效应比和水泥土的承载比,同时基于最小势能原理推求了考虑挡墙空间变形作用的墙顶位移解析解。将位移解析解与弹性支点法计算的位移值、实测位移值进行对比分析,并结合模型试验对影响SMW工法空间变形效应比和承载比的因素进行了深入讨论。结果表明:考虑空间变形作用的解析解相比弹性支点法计算结果更加接近实测值;SMW工法的挡墙高长比、水泥土的弹性模量以及墙厚对空间变形效应比和水泥土承载比有显著的影响。

唐代的南山大师道宣,是四分律宗的鼻祖,也被佛教史学者称为"中国佛教史学之父",在中国乃至东亚佛教史上有着不灭的光辉。在道宣涉及"佛教历史"的三大著作《续高僧传》《广弘明集》《集神州三宝感通录》之中,《广弘明集》与《集神州三宝感通录》均成书于麟德元年。特别是对于深感天年将近的道宣来说,《集神州三宝感通录》可以说寄托了他最后的深意。从《集神州三宝感通录》的北周末年至隋代的佛教史"感通"叙述中,可以探究道宣对于隋代重兴佛法的深意。通过对隋文帝手敕修建的相州大慈寺塔、隋京师日严寺石影像等条目的分析,将其与北周武帝的废佛灭法、隋初的尉迟迥反叛、隋末杨玄感叛乱、大业六年弥勒教盗贼之乱等事件相结合,可窥视道宣《集神州三宝感通录》佛教史书写的背后之意。中古时代末法思想盛行,道宣力图对隋文帝与隋炀帝采取不同的叙述与评判立场,其实隐含了他对唐高祖武德沙汰令的否定以及末法危机感,也蕴含了他对唐高宗、武则天护法的希望。

唐代是古代中国对世界最有吸引力的朝代之一。上个世纪以来,欧美及日本涌现出为数不少的关于唐太宗李世民的人物传记。而国内学界对于这些海外唐太宗人物传记作品的翻译或研究,或限于语言障碍,或限于文献获取,迄今进展不大,甚为可惜。本文选取国内尚未介译过的、上世纪三十及六十年代费子智(1902-1992,***)的Son of Heaven:A Biography of Li Shih-Min,Founder of the T’ang Dynasty与谷川道雄(1925-2013)的《唐の太宗》这两种英文、日文的人物传记。通过分析他们的传记描写结构、手法,特别是选取具体事件的叙述方式,来探求欧美及日本对于唐帝国鼎盛期的缔造者——'天可汗'唐太宗的描写、构造、想象的异同之处,以及他们写作思想之时代烙印、学术背景及相关深层次理路。

義熙年間劉裕的兩次重要的北伐,一是對鮮卑族的南燕,一是對羌族的後秦。前者史書多稱“廣固之役”,當時文筆表策,均出王誕之手;後者之軍中文書則多由北地傅亮掌筆。義熙十二年至義熙十四年,劉裕北伐軍攻陷天下之中洛陽、長安,傅亮爲此撰寫了《爲宋公修張良廟教》與《爲宋公修楚元王墓教》。結合義熙年間北伐後秦行軍的地理位置變化,可考證“二教”的具體撰寫時間;今將“二教”置於劉裕身分“宋公”、“加九錫的宋公”、“宋王”的關鍵節點再加以文本詳考。在宋初“經史之學”向劉宋中葉“詞賦之學”的演進途中,傅亮是一位非常有標誌意義的人物,他在文學史甚至是在中古政治史上的地位應該得到重新審視。
