新时代党的自我革命话语是中国特色政党话语体系的关键要素,是在马克思主义建党学说的理论指导下,汲取中华优秀传统文化,并基于当前形势对传统革命话语进行适应性调整而生成的党建话语方式。党的自我革命话语体系的基本结构分别为自我革命话语的主体、客体、主客体合力及内嵌其中的自我革命话语的叙事内容。其中,中国共产党自身具有双重属性,既是自我革命话语的制定者,又是自我革命话语语境下的被约束对象。在坚定不移推进全面从严治党的伟大实践中,理应从占据话语网络传播空间高地、增强话语内容创新、站稳话语叙事起点和提升话语学理性阐释这四个建构路径入手,进一步完善新时代中国共产党自我革命话语体系的研究范式。

背景与目的:早期预测结直肠癌(colorectal cancer,CRC)肺转移瘤经过射频消融(radiofrequency ablation,RFA)治疗后的局部肿瘤无进展生存期(local tumor progression-free survival,LTPFS)具有重要的临床意义。影像组学在肿瘤预后预测方面已有一定的探索。本研究旨在构建基于影像组学的诺模图预测CRC肺转移患者RFA治疗后的LTPFS。方法:本研究回顾性分析2016年8月—2019年1月复旦大学附属肿瘤医院介入治疗科收治的172例伴有401个肺转移病灶的CRC患者。本研究通过复旦大学附属肿瘤医院医学伦理委员会的审查(伦理编号:2402291-24)。将患者的RFA术前及术后即刻计算机体层成像(computed tomography,CT)图像通过数据增强后,人工分割靶病灶和RFA后区域后提取影像组学特征。采用最大相关最小冗余算法(maximum relevance and minimum redundancy algorithm,MRMRA)和最小绝对值收敛(least absolute shrinkage and selection operator,LASSO)回归模型进行特征筛选。基于筛选后的影像组学特征和多因素分析筛选的临床变量,分别构建临床模型、影像组学模型和融合模型。计算一致性指数(concordance index,C-index)和受试者工作特征(receiver operating characteristic,ROC)曲线的曲线下面积(area under curve,AUC)来评估3种模型的预测性能,最后绘制最佳模型对应的诺模图。结果:在所有肺转移瘤中,最终复发的病灶有102个(25.4%),完全缓解(complete response,CR)的病灶有299个(74.6%)。中位随访时间为21个月(95%CI:19.466~22.534),RFA术后的1、2和3年的LTPFS率分别为76.5%(95%CI:72.0~80.4)、72.1%(95%CI:66.6~76.9)和69.9%(95%CI:64.0~75.1)。无论在训练集还是测试集中,基于LASSO回归模型最终筛选的12个影像组学特征和多因素分析筛选的4个临床变量而构建的融合模型预测LTPFS的AUC最高,C-index分别为0.890(95%CI:0.854~0.927)和0.843(95%CI:0.768~0.916)。结论:基于影像组学特征和临床变量的融合模型预测CRC肺转移患者RFA治疗后的LTPFS是可行的,并且其性能优于单一影像组学模型和临床模型。同时,融合模型的诺模图可以更直观地预测CRC肺转移患者RFA治疗的预后,协助临床医师为患者制订个体化的随访复查方案,灵活地调整治疗策略。
