临床不合理联合用药分析

目的 提高医师用药水平，减少药源性疾病的发生，确保病员身体健康。方法 对1999—2002年医师处方中的联合用药情况进行分析。结果 处方中有产生降效、毒副反应等不合理联合用药。结论 提高医师的联合用药水平，确保用药安全有效，是医师、药师、护士等相关人员目前和今后值得高度重视的问题。

浅谈中西药的合理联用

随着我国中西药学科结合的深入发展，中西药联合应用普及各个临床学科成为我国临床用药的优势与特色。只要联用得当、合理，可相互取长补短，使疗效增强，病程缩短，药物的毒副作用减少，有时可以取得意想不到的效果。若中西药配伍不当、剂量或用法不妥，则使药效降低和消失，毒副反应增加或引起药源性疾病，延误病情，甚至危及生命。本文从中西药合理联用和不合理联用事例两方面加以分析，以期对临床中西药联合配伍应用有所裨益。

Performance Evaluation of Bioethanol Production through Continuous Fermentation with a Settling Unit

This paper analyses a model for the production of bioethanol that has been calibrated against laboratory data by previous researchers. The authors investigate the improvement in productivity that can be obtained when a centrifuge is used to recycle cells that would otherwise leave the reactor system in the efficient stream. The authors compare the performance of a double reactor cascade, possible employing a settling unit, against that of a single reactor. For the former case, this paper considers the reactor configuration in which the settling unit recycles from the effluent stream of a reactor back in the influent of the same reactor.
