The implementation of cancer precision medicine requires biomarkers or signatures for predicting prognosis and therapeutic benefits.Most of current efforts in this field are paying much more attention to predictive accuracy than to molecular mechanistic interpretability.Mechanism-driven strategy has recently emerged,aiming to build signatures with both predictive power and explanatory power.Driven by this strategy,we developed a robust gene dysregulation analysis framework with machine learning algorithms,which is capable of exploring gene dysregulations underlying carcinogenesis from high-dimensional data with cooperativity and synergy between regulators and several other transcriptional regulation rules taken into consideration.We then applied the framework to a colorectal cancer (CRC) cohort from The Cancer Genome Atlas.The identified CRC-related dysregulations significantly covered known carcinogenic processes and exhibited good prognostic effect.By choosing dysregulations with greedy strategy,we built a four-dysregulation (4-DysReg) signature,which has the capability of predicting prognosis and adjuvant chemotherapy benefit.4-DysReg has the potential to explain carcinogenesis in terms of dysfunctional transcriptional regulation.These results demonstrate that our gene dysregulation analysis framework could be used to develop predictive signature with mechanistic interpretability for cancer precision medicine,and furthermore,elucidate the mechanisms of carcinogenesis.

针对目前石油专用管服役质量评价存在考虑要素单一、评价过程不集成等问题,提出了一种制造与服役要素融合的石油专用管质量水平指标体系构建和评价方法。首先,根据石油专用管服役过程中的特点,构建了制造与服役要素融合的石油专用管质量水平评价指标体系;其次,在层次分析法和属性数学的理论基础上提出了石油专用管服役质量指数的概念,并给出其计算方法,实现了融合制造和服役要素的石油专用管质量量化评价;最后通过实例验证了本文所提出的方法的有效性,结果表明所提方法可以实现从石油专用管的制造到服役过程、从底层数据到宏观质量状态的集成
