微藻因生长速率快、细胞脂质含量高及具有生物隔离二氧化碳能力,已作为新一代生物质能源受到广泛关注.然而,投入大量淡水资源并需在生长期间持续提供营养物质已成为规模化培育微藻的主要障碍.将微藻培育系统与废水处理相结合是经济可行的污水资源化方案.基于微藻生长期间对氮磷等营养物质的利用机制,本文综述了微藻在各类废水生物处理过程中的应用情况,着重分析了其对废水中有机与无机化合物、重金属以及病原体的去除或抑制能力.同时,考察了废水初始营养物浓度、光照、温度、pH与盐度以及气体交换量等环境因素对微藻生长代谢的影响.此外,结合微藻规模化应用所面临的问题,对微藻废水处理技术的应用前景及发展方向进行了展望,旨在为水生态系统的建设与管理提供参考.

血清游离轻链及其κ/λ比率在多发性骨髓瘤患者中的临床意义研究. 分析血清游离轻链(sFLC)及sFLC-κ/λ比率在初诊多发性骨髓瘤(MM)患者中的表现,为MM的诊断、治疗和预后评价提供依据. 选取我院住院初次确诊为MM的患者43例,sFLC增高的其他疾病患者40例。分析初诊MM患者的临床特征;根据MM患者的sFLC类型分为sFLC-κ组和sFLC-λ组,分析2组sFLC水平与临床指标的相关性;分析sFLC-κ/λ比率在MM患者与非MM患者中的表现情况;依据受累/非受累sFLC比值100为界分为低比率组和高比率组,分析2组患者的临床指标是否有差异. 初诊MM患者中IgG类型最多。sFLC-κ组和sFLC-λ组血红蛋白水平与sFLC呈...
