Castleman disease is a relatively rare entity, with the hyaline-vascular type the predominant form. Although the plasma cell type is uncommon, it still comprises approximately 10% of cases of localized diseases. In addition, the abdomen is a rare site for involvement and localized Castleman disease of the plasma cell type in the abdomen is rare. The radiologic features of localized plasma cell type in the abdomen are mostly limited to case reports. In addition to the conventional imaging findings, we present some new imaging findings of localized plasma cell type in the abdomen.

A degradable poly（lactic-co-glycolic acid, LA：GA=80：20）（PLGA） urethral tubular scaffold was fabricated by electrospinning. In order to enhance the mechanical properties, the scaffold was crosslinked with glutaraldehyde. The structure and properties of the crosslinked scaffolds were investigated by the mechanical property testing, scanning electron microscopy（SEM）, degradability test in vitro and 3-（4,5）-dimethylthiahiazo（-z-yl）-3,5-diphenytetrazo- liumromide（MTT）. The results show that the scaffold has the nano-structure. The pore size and the porosity are suitable for cell seeding, growth and extracellular matrix production. Although influenced by the crosslinking slightly, the pore size and the porosity could still support cell proliferation and tissuse formation. The mechanical properties are remarkably increased by the crosslinking of glutaraldehyde, and it could meet the demands of a urethral stent. The scaffold could completely collapse within 70 d. The results of the biocompatibility test show that the PLGA scaffold had no cytotoxicity.

磷是现阶段制约太湖水环境持续改善的关键指标,也是太湖蓝藻暴发的重要诱因之一.为揭示太湖不同介质中磷元素的特征及其之间的迁移转化关系,对太湖全湖表层水、上覆水、间隙水和沉积物中TP浓度进行了调查分析.结果表明,太湖表层水和上覆水ρ(TP)处于地表水Ⅰ~Ⅳ之间,平均值分别为0.09 mg·L^(-1)和0.085 mg·L^(-1),间隙水ρ(TP)是上覆水的4~8倍,平均值为0.558 mg·L^(-1).太湖沉积物中TP负荷主要集中在表层0~30 cm,ω(TP)范围在413~1531 mg·kg^(-1),深层(30~100 cm)沉积物的TP含量总体较为稳定.太湖沉积物-水界面的磷元素交换总体比较活跃,不同介质中TP污染的空间分布一致性较强,总体表现为西北部高于东南部,西北部湖区中,竺山湖不同介质中TP含量均达到严重污染的程度,梅梁湖和西部沿岸区因间隙水与上覆水TP浓度梯度差较大,内源释放风险较高.TP含量在沉积物中总体表现为随深度增加而降低的趋势;近现代人类活动的影响主要聚集在表层0~30 cm沉积物,该泥层是底泥生态清淤需要重点考虑的泥层.
