聚硅氧烷是应用广泛的一种特种有机硅材料,折射率是衡量聚硅氧烷性能的重要指标。应用基团贡献法建立了适用于聚苯基甲基硅氧烷体系的分子量-折射率模型,结合自由体积理论对模型进行了修正。修正后的模型能够根据分子量和温度有效地预测聚苯基甲基硅氧烷的折射率,相对误差在±0.2%范围内。根据修正后的模型阐述了分子量、温度对折射率的影响:折射率随着分子量的增大而升高,最终趋于一定值;折射率随着温度的升高明显下降。研究结果可为高折射率聚硅氧烷的设计与合成提供参考。

Myelodysplastic syndromes （MDS） are a heterogeneous group of clonal disorderscharacterized by ineffective hematopoiesis; they manifest clinically as anemia, neutropenia, and thrombocytopenia.1＇2 Higher risk MDS include patients in the intermediate-2 and high-risk categories of the International Prognostic Scoring System （IPSS）, as well as patients with MDS secondary to radiation or chemical exposure.3.The patients with higher risk MDS have a peculiar propensity to evolve into acute myeloid leukemia （AML）, and have a median survival of 〈12 months.4 Management of higher risk MDS varies from supportive care with transfusions or hematopoietic cytokines to high-intensity3.chemotherapy or hematopoietic stem cell transplantation. The impact of intensive myelosuppressive chemotherapy, similar to AML induction therapy, has been investigated. The results are comparable to the reported outcome of patients with AML, i.e. complete remission （CR） rates of 40%-60% and median overall survival （OS） of 8-12 months,s Thus, innovative approaches are needed for the treatment of higher risk MDS.
