Joint members were made of ll-ply hardwood plywood of 19 mm thickness. Dowels were fabricated of Beech and Hornbeam species. Their diameters （6, 8 and 10 mm） and depths of penetration （9, 13 and 17 ram） in joint members were chosen variables in our experiment. By increasing the connector＇s diameter from 6 to 8 mm, the bending moment resistance under diagonal compressive load was increased, while it decreased when the diameter was increased from 8 to 10 mm. The bending moment re- sistance under diagonal compressive load was increased by increasing the dowel＇s depth of penetration. Joints made with dowels of Beech had higher resistance than dowels of Hornbeam. Highest resisting moment （45.18 N.m） was recorded for joints assembled with 8 mm Beech dowels penetrating 17 mm into joint members Lowest resisting moment （13.35 N.m） was recorded for joints assembled with 6 mm Hornbeam dowels and penetrating 9 mm into joint members.展开更多
尼曼-匹克病C型(Niemann-Pick disease type C,NPC)是常染色体隐性遗传的罕见病,以肝脾肿大和神经系统功能障碍为主要表现。本文报告1例35岁女性患者,因“渐进性双手抖动、动作笨拙23年,精神异常14年”就诊。患者12岁起病,因检查提示铜...尼曼-匹克病C型(Niemann-Pick disease type C,NPC)是常染色体隐性遗传的罕见病,以肝脾肿大和神经系统功能障碍为主要表现。本文报告1例35岁女性患者,因“渐进性双手抖动、动作笨拙23年,精神异常14年”就诊。患者12岁起病,因检查提示铜代谢指标异常及脾肿大被误诊为肝豆状核变性,口服青霉胺及苯海索症状改善。至21岁时出现精神异常,予以青霉胺与利培酮治疗后症状控制。本次入院发现患者虽有神经精神症状、脾大及铜生化异常,但始终未见角膜色素环,颅脑MRI亦缺乏特征性改变,最终经基因检测及骨髓细胞学检查确诊为NPC。口服麦格司他胶囊及利培酮,随访1年病情稳定。本病例提示,对于以神经精神症状起病并伴有脾肿大的患者,需高度警惕NPC的可能,避免误诊。展开更多
