AIM: To develop a prognostic gene set that can predict patient overall survival status based on the whole genome expression analysis. METHODS: Using Illumina HumanWG-6 BeadChip followed by semi-supervised analysis, we analyzed the expression of 47 2.6 transcripts in two batches of gastric cancer patients who underwent surgical resection. Thirty-nine samples in the first batch were used as the training set to discover candidate markers correlated to overall survival, and thirty-three samples in the second batch were used for validation. RESULTS: A panel of ten genes were identified as prognostic marker in the first batch samples and classified patients into a lowand a high-risk group with significantly different survival times (P = 0.000047). This prognostic marker was then verified in an independent validation sample batch (P = 0.0009). By comparing with the traditional Tumor-node-metastasis (TNM) staging system, this ten-gene prognostic marker showed consistent prognosis results. It was the only independent prognostic value by multivariate Cox regression analysis (P = 0.007). Interestingly, six of these ten genes are ribosomal proteins, suggesting a possible association between the deregulation of ribosome related gene expression and the poor prognosis. CONCLUSION: A ten-gene marker correlated with overall prognosis, including 6 ribosomal proteins, was identified and verified, which may complement the predictive value of TNM staging system.

1维综合孔径微波辐射计通常会采用G矩阵模型法来实现亮温图像的重建。对于1维辐射计系统,成像过程主要包含:辐射计仪器观测2.全视场的目标场景亮温,得到1维的可见度函数采样值,再通过对系统参数矩阵G求逆来实现目标场景的1维图像重建。由于1维辐射计系统的采样基线只分布在空间频率域的1个维度上,所以在图像重建过程中,需要实现矩阵G从2.到1维的转换。对此,该文提出了两种适用于1维综合孔径微波辐射计成像的G矩阵修正方法。并针对目前已经完成的8单元辐射计地面样机系统和目前正在研制的10单元盐度计样机系统,通过理论分析和仿真实验,验证了G矩阵修正法对1维综合孔径微波辐射计成像结果的改善效果,以及对天线方向图旁瓣恶化所引入成像误差的有效抑制。

目的本文通过开展白癜风患者病变表皮与正常表皮的比较蛋白质组学研究,发现和鉴定白癜风患者病变表皮与正常表皮之间的差异表达蛋白,以探讨白癜风患者表皮发生病变的分子机制。方法首先,建立和优化了表皮样品中蛋白质的最佳酶切条件。其次,采用基于串联质谱标签(TMT)标记的定量蛋白质组学技术策略开展了稳定期白癜风患者病变表皮与正常表皮的比较蛋白质组学研究,并筛选了差异表达蛋白。最后通过生物信息学分析工具及数据库(GO、KEGG、STRING、GSEA)对差异蛋白进行功能富集分析。结果优化所得到的最佳酶解条件是由Lys-C(酶∶底物,1∶100)和胰酶(酶∶底物,1∶50)组合而成的顺序酶切。比较蛋白质组学研究共鉴定4496个蛋白质,其中181个蛋白质为白癜风患者病变表皮中的差异表达蛋白。生物信息学分析表明差异表达蛋白主要与代谢、免疫、氧化还原和细胞黏附相关。其中119个上调蛋白主要参与角质化、转录、氧化应激及蛋白酶解等过程。62.下调蛋白主要参与细胞内物质运输、谷胱甘肽代谢和肌动蛋白细丝封端等过程。结论比较蛋白质组学研究揭示了白癜风患者病变表皮与正常表皮之间主要存在角质化、免疫、脂质代谢和氧化还原等方面的功能差异,发现了PRDX1、PRDX2.EEF2.ITGB1、SPTBN2.ANXA1及PFKL等蛋白质为潜在的白癜风患者病变表皮功能失调的关键蛋白质。
