Pulmonary Langerhans＇ cell histiocytosis （PLCH） is an isolated form of Langerhans＇ cell histiocytosis thatusually develops in cigarette smokers.1＇2^ PLCH usually has typical light microscopic morphology with a spectrum of progressive changes.2-4^ It is characterized by peribronchiolar Langerhans＇ cell infiltrates mixed with macrophages, lymphocytes and eosinophils, that form stellate nodules. The nodular lesions are frequently cavitated and form thick- and thin-walled cysts, which are thought to represent enlarged airway lumina. PLCH lesions display temporal microscopic heterogeneity, with a progression from dense cellular nodules to cavitary nodules with increasing degrees of fibrosis that may extend along alveolar walls. In advanced cases,

Minimum amount of extracting solvent of AB/BC countercurrent extraction separation using organic feed

引用

Journal of Rare Earths 2014年第5期32卷 439-444页

作者：程福祥吴声张玻刘艳王嵩龄廖春生严纯华 China Minmetals (Beijing) Research Institute of RE Co. Ltd Beijing National Laboratory for Molecular Sciences State Key Laboratory of Rare Earth Materials Chemistry and Applications PKU-HKU Joint Lab on Rare Earth Materials and Bioinorganic Chemistry Peking University

For an AB/BC countercurrent extraction separation using organic feed, the conditions to have minimum amount of ex- tracting solvent （Smin） and minimum amount of scrubbing agent solution （Wmin） were discussed, and the formulae of both Sroin and Wmin were deduced. It was shown that only when the ratio of flowrate of central component B leaving aqueous outlet to that leaving organic outlet took a certain optimal value, the AB/BC separation could have Smin as well as Wmin, and this optimal ratio was decided by the separation factors between the three components but independent of feed composition. Smin was only relative to the separation factor of A/C pair but regardless of the separation factors of other pairs as well as feed composition, whereas Wmin was determined by the separation factors between the components together with feed composition. Meanwhile it was also found that the organic stream out of feed stage was same composition as the initial organic feed when the separation system was given by the two minimum amounts and its steady state was achieved. Finally the results above were used to design a LuYb/YbTm separation case and the stage-wise compositions of each component in both the organic and the aqueous phase at steady state were given by computer simulation.

中医对黄疸的分类经历了辨病分类、辨病与辨症分类并行、辨证分类兴起并成为主体三个历史阶段。金元以前,中医辨治黄疸主要有以病为纲下的辨证论治以及单纯辨症两种方式;金元以后,黄疸的辨治逐渐脱离了疾病的主体,走向单纯的辨证论治。通过对黄疸辨治由辨病转向辨证的分析,可以帮助我们更加深入地理解中医学诊疗模式的变迁,更好地把握中医学的病证关系、明晰中医病名与病症概念混淆等问题的内在原因。回溯、挖掘中医辨病的理论与经验,结合现代研究进行深入解析,有助于中医学在当代的创新与发展。
