Cell-free RNA(cf RNA) allows assessment of health, status, and phenotype of a variety of human organs and is a potential biomarker to non-invasively diagnose numerous diseases. Nevertheless, there is a lack of highly efficient and bias-free cf RNA isolation technologies due to the low abundance and instability of cf ***, we developed a reproducible and high-efficiency isolation technology for different types of cell-free nucleic acids(containing cf RNA and viral RNA) in serum/plasma based on the inclusion of nucleic acids by metal-organic framework(MOF) materials, which greatly improved the isolation efficiency and was able to preserve RNA integrity compared with the most widely used research kit method. Importantly, the quality of cf RNA extracted by the MOF method is about 10-fold that of the kit method, and the MOF method isolates more than three times as many different RNA types as the kit method. The whole transcriptome mapping characteristics of cf RNA in serum from patients with liver cancer was described and a cf RNA signature with six cf RNAs was identified to diagnose liver cancer with high diagnostic efficiency(area under curve = 0.905 in the independent validation cohort) using this MOF method. Thus, this new MOF isolation technique will advance the field of liquid biopsy, with the potential to diagnose liver cancer.

断层、滑坡、液化等地质灾害引起的场地大变形对埋地管道结构安全产生严重的威胁。开展了中密砂中埋地管道-砂土水平横向相互作用的系列三维数值模拟,根据数值模拟的结果探讨了不同深径比下管-砂土横向相互作用时土体的破坏模式,研究了深径比对砂土极限承载力的影响。基于管周土体的破坏模式建立了简化计算模型,根据极限平衡理论推导了管道水平横向运动时砂土极限承载力计算公式。研究结果表明:极限状态下,浅埋管道周围土体形成延伸到地表的破裂面,轮廓线近似对数螺线;砂土的极限承载力随着深径比增加,最终在临界深径比处达到稳定;随着深径比的增加,土体发生剪切滑动破坏所需的管道位移也逐渐增大;由于横向承载力系数取值依据不同,国内外规范计算所得土体极限承载力差异较大;得到的解析解能够较好地预测中密砂土中浅埋管道水平横向运动时土体的极限承载力。
