Based on the design of an infectious disease hospital in Tianjin, this study provides reasonable airflow organization design guidance and operation guidance for the negative pressure isolation wards in the hospital buildings through computational fluid dynamics (CFD) numerical simulation. In this study, a theoretical analysis was carried out on the demand for the air change numbers provided in different standards of the negative pressure isolation ward. This study compares the pollutant discharge time and carries out the energy consumption analysis. Finally, this study gives reasonable ventilation frequency of the negative pressure isolation ward during the outbreak of infectious period, and provides guidance for its air conditioning operation.

【目的】评价人工全髋关节置换术中两种不同髋臼锉磨深度的疗效。【方法】对2015年3月至2016 年2月在本院行人工全髋关节置换术的119例股骨颈骨折患者的临床及影像学资料进行回顾性分析，按随机数 字表分为A、B组。A组患者锉磨髋臼时中央部分锉磨达到卵圆窝骨质，髋臼周边部分（前、后、上、下）达到软骨 下骨或松质骨；B组患者锉磨髋臼时髋臼前、后壁露出软骨下骨，保留部分软骨下骨。比较2组患者手术时间、术 中出血量、术中安装髋臼假体时是否容易达到稳定、术后3个月、2年髋关节Harris评分。【结果】与B组相比，A 组患者平均手术时间长、出血量大，术中相对不易达到满意的初始稳定性（P < 0.05）；术后30 d，A组手术患者髋 关节Harris评分（86.9 ± 5.4）明显低于B组［（89.1 ± 5.5），P < 0.05］。术后2年，两组患者髋关节Harris评分没有统 计学差别（P > 0.05）。【结论】全髋关节置换术中锉磨髋臼仅达髋臼前后壁软骨下骨的方法比锉磨达到髋臼内 壁的方法操作时间更短，术中髋臼假体更容易达到初始稳定性，术后短期可以获得较好的髋关节功能。

【目的】探讨借助三维CT的术前规划在个性化手术工具（PSI）辅助初次人工膝关节表面置换中的应 用。【方法】54位患膝骨关节炎的患者依据随机、 “双盲”的方法分为传统工具（CI）组和PSI组，每组27位患者，进 行初次膝关节表面置换术。两组术前根据三维图像及截骨数据来选取假体大小。PSI组胫骨平台假体的旋转定 位依据形合度匹配，并允许假体边缘在一些部位有限超出截骨面边缘。CI组术中依据传统方法进行测量和截 骨。比较两组患者手术时间，调整假体大小的例次，后髁截骨量，术后X线平片情况，术后3个月、1年AKS评 分。【结果】两组手术时间无统计学差异；PSI组术中无需调整假体大小；CI组有8例所用假体与术前计划不同，均 小于术前依据三维CT的测量结果；CI组平均后髁截骨量大于PSI组。术后3个月PSI组患者AKS高于CI组；术 后1年两组AKS评分没有统计学差异。【结论】术前薄层CT扫描结果可用于术前截骨计划，有利于正确选择股骨 假体尺寸和位置。股骨和胫骨假体在一定部位有限超出截骨面边缘，不会增加术后患者不适感。使用解剖形态 的胫骨假体时，可以依据最佳覆盖原则确定胫骨假体的旋转定位。

Large shrinkage usually occurs in the hydration process of ultra-high performance concrete (UHPC), which is not conducive to its early crack control. In order to solve this problem, UHPC was prepared by replacing quartz sand with coral sand loaded with shrinkage reducing agent according to a certain volume substitution rate, and the workability performance, mechanical properties and volume stability of UHPC were tested according to relevant standards. The results show that the coral sand loaded with shrinkage reducing agent can weaken the effect of shrinkage reducing agent on retarding hydration, increase the fluidity and reduce the development of compressive strength of UHPC. Due to the synergistic effect of the internal curing mechanism and shrinkage reducing agent in coral sand, the coral sand loaded with shrinkage reducing agent significantly reduced the autogenous shrinkage and drying shrinkage of UHPC. The optimum mixing is to replace 45 % quartz sand with coral sand loaded with 30.8% shrinkage reducing agent. The 28 d compressive strength of UHPC decreases by 14.9%, the 7 d autogenous shrinkage decreases by 82.9% and the 28 d drying shrinkage decreases by 54.1%. Although the compressive strength reduces slightly, the volume stability of UHPC has been well improved. [ABSTRACT FROM AUTHOR]
