And, using the interaction potential function method, the intermolecular interaction energies between cholesterols, the complexes, and Cu2+ , Zn2+, Cd2+, Cr3+-cholesterol complexes were obtained. Based on the interaction energy, the medical role of biometals in hypercholesterolemia concerned with arteriosclerosis were explained successfully.展开更多
文摘目的探讨总胆固醇/高密度脂蛋白胆固醇(total cholesterol/high density lipoprotein-cholesterol,TC/HDL-C)联合脉压指数(pulse pressure index,PPI)、动脉硬化指数(arteriosclerosis index,AI)对急性缺血性脑卒中(acute ischemic stroke,AIS)的预测价值。方法选取2020年10月至2022年10月安徽医科大学附属宿州医院收治的AIS患者424例纳入病例组,选取同期健康者202名纳入对照组。比较两组研究对象的TC/HDL-C、PPI、AI差异。采用多因素Logistic回归分析影响AIS的危险因素,采用受试者操作特征曲线(receiver operating characteristic curve,ROC曲线)分析TC/HDL-C、PPI、AI对AIS的预测价值。结果病例组患者的收缩压、舒张压、血糖、同型半胱氨酸均显著高于对照组(P<0.05)。病例组患者的PPI、AI、TC/HDL-C水平均显著高于对照组(P<0.05)。多因素Logistic回归分析结果显示,PPI、AI、TC/HDL-C、同型半胱氨酸、血糖升高均是发生AIS的独立危险因素(P<0.05)。ROC曲线结果显示,PPI、AI、TC/HDL-C预测AIS的曲线下面积(area under the curve,AUC)分别为0.669、0.597、0.597,三者联合预测AIS的AUC为0.774。结论TC/HDL-C、PPI、AI与AIS的发病密切相关,三者联合对AIS有较高的预测价值。
