文摘目的:探讨机器学习结合CT影像组学特征构建模型预测2型糖尿病(type 2 diabetes mellitus,T2DM)患者椎体脆性骨折的准确性。方法:回顾性收集140例(新发椎体脆性骨折的T2DM患者70例,对照组70例)患者CT图像和临床资料。另收集18例(椎体脆性骨折的T2DM患者16例,对照组2例)患者的前次CT图像和临床资料作为外部验证集。应用单因素分析、Pearson相关分析、最小冗余度最大相关度算法、二元logistic回归分析和最小绝对值收缩和选择算子模型筛选出最佳特征。基于支持向量机、多层感知器、极端梯度提升(eXtreme Gradient Boosting,XGBoost)构建预测模型。应用受试者工作特征曲线下面积(area under the curve,AUC)对模型效能进行评估。结果:从每例患者的CT图像中提取了1037个影像组学特征,然后精简为14个影像组学特征。17个临床特征中性别、年龄、体质指数是预测结果的独立因素。其中XGBoost分类器表现最好,训练集中XGBoost模型的AUC分别为1.000、0.929、1.000;测试集中分别为0.954、0.862、0.969。结论:基于临床及影像组学特征构建的XGBoost模型可作为预测T2DM患者椎体脆性骨折的一种无创性辅助工具。

文摘Through the collection and systematic analysis of documents related to window views of hospitals,it is found that natural window views had a significant impact on patients’health benefits.The research focused on three aspects:“shortening length of stay”,“pain reduction”and“improvement of recovery rate”,mainly covering three types of patients:“heart patients”,“postoperative patients”and“patients of rehabilitation centers”.Based on the above analysis,summary and sorting,new directions and perspectives of hospital environment design and research under the concept of comprehensive health of people’s physiological,psychological and social adaptation will be obtained to provide references for the research and practice of health architecture,rehabilitation architecture,biophile design and other fields.
