Coating Process of Paeonol Sustained Release Pills

[Objectives] To study the coating process of paeonol sustained release pills by extrusion-spheronization method taking ethyl cellulose as the coating material. [Methods] Paeonol pills were made by Auari AW-95 Full Automatic Pill Making Machine. Coating of paeonol sustained release pills was prepared by Auari Mini Pill Polishing Machine. The prescription and process factors of paeonol sustained release pills coating were investigated by single factor experiment and orthogonal experiment. The release of paeonol sustained release pills was determined according to the cumulative release curve of paeonol. [Results] The prepared paeonol sustained release pills released slowly within 24 h, and the release rate reached 80% in 12 h. [Conclusions] The prepared paeonol sustained release pills basically meet the 24 h sustained release standard, and can be further developed and applied.

卵巢卵黄囊瘤的声像图特征、临床病理与预后分析

目的分析并总结卵巢卵黄囊瘤(OYST)的声像图特征、临床病理特点及预后。方法回顾性分析2010年1月至2020年12月在南京大学医学院附属鼓楼医院行超声检查、经手术病理证实的OYST患者10例,记录患者的临床资料、声像图特点、病理结果及分期、治疗方式及预后。通过与病理结果进行对照,分析各例患者超声特点,总结能够提示OYST的主要或特定声像图特征。结果OYST患者年龄偏小(≤30岁),肿块体积大(最大径94~265 mm),肿瘤内部回声以实性为主,常单侧发病,形状规则,血流信号丰富,甲胎蛋白常异常增高(多数>1000 ng/ml)。10例OYST患者均选择手术治疗,其中1例患者手术后因肿瘤全身转移伴盆腔脓肿死亡,1例合并妊娠者足月顺产一健康婴儿。2例ⅢA期患者死亡,2例ⅢC期及6例ⅠC期患者均无瘤生存,其中6例患者保留生育功能,化疗后3个月内均恢复正常月经,3例患者已完成生育,生育子女健康。结论OYST具有某些特定的超声征象,正确认识其声像图特征并结合相关临床及实验室检查,对于该病的术前评估至关重要。
