Results indicated that the morphology of products of hydration in 1TZ was similar to the cement matrix but different by amount, size and crystal features. Elements Ca, Si, AI and Mg were obviously enriched in ITZ and uniformity of their distribution grew with age. MgO was non- uniformly distributed in concrete, accounting for 8.47% and 4.53% respectively in paste and ITZ area despite of fully mixture in construction, yet MgO showed inclination of migrating towards ITZ area with in-depth hydration and the gap in between was mit- igated from 3.94% at 7 d to 1.31% at 240 d so far as 5% of light- burnt MgO was incorporated.展开更多
目的观察养阴润肠方治疗慢性传输型便秘临床疗效。方法符合纳入标准的32例慢性传输型便秘患者,使用养阴润肠方治疗3个疗程,每个疗程7d,分别记录治疗前、2个疗程后、3个疗程后、停药1个月后便秘患者生活质量自评量表(patient assessment ...目的观察养阴润肠方治疗慢性传输型便秘临床疗效。方法符合纳入标准的32例慢性传输型便秘患者,使用养阴润肠方治疗3个疗程,每个疗程7d,分别记录治疗前、2个疗程后、3个疗程后、停药1个月后便秘患者生活质量自评量表(patient assessment of constipation quality of life questionnaire,PAC-QOL)评分及Cleveland便秘评分。结果治疗结束时治愈17例,显效8例,有效4例,无效3例,总有效率为90.6%。治疗前后PAC-QOL比较,在治疗2个疗程后、3个疗程后、停药1个月后,生理积分、担忧度积分、满意度积分、总分均显著减少(P<0.01);3个疗程后、停药1个月后,心理积分显著减少(P<0.01);与治疗前比较,治疗2个疗程后、3个疗程后、停药1个月后Cleveland评分均显著减少(P<0.01)。结论养阴润肠方治疗慢性传输型便秘在全身整体性调节和提高生活质量等方面疗效确切。展开更多
