Excitation energies, electromagnetic transition strengths, quadrupole and magnetic dipole moments, and △（E2/M1） mixing ratios have been described systematically. Mixed symmetry states are investigated. It is seen that the properties of low-lying levels in these isotopes, for which the comparison between experiment and theory is possible, can be satisfactorily characterized by the Interacting Boson Model-2.展开更多
目的探讨三酰甘油葡萄糖乘积(triglyceride-glucose index,TyG)指数和血浆致动脉粥样硬化指数(atherogenic index of plasma,AIP)与老年冠心病(coronary heart disease,CHD)合并2型糖尿病(type 2 diabetes mellitus,T2DM)患者冠状动脉...目的探讨三酰甘油葡萄糖乘积(triglyceride-glucose index,TyG)指数和血浆致动脉粥样硬化指数(atherogenic index of plasma,AIP)与老年冠心病(coronary heart disease,CHD)合并2型糖尿病(type 2 diabetes mellitus,T2DM)患者冠状动脉正性重构的关系。方法按照住院先后顺序选取2022年1月至2023年6月河南科技大学第一附属医院心血管内科收治的老年CHD合并T2DM患者120例,根据重构指数分为正性重构组47例和非正性重构组73例。比较2组临床资料;采用多因素logistic回归分析冠状动脉正性重构的危险因素;采用Spearman相关性分析TyG和AIP与冠状动脉正性重构的相关性;采用ROC曲线分析TyG和AIP对冠状动脉正性重构的预测价值。结果正性重构组吸烟、三酰甘油、糖化血红蛋白、TyG、AIP显著高于非正性重构组,高密度脂蛋白胆固醇、血钙水平显著低于非正性重构组(P<0.05,P<0.01)。单因素logistic回归分析显示,吸烟、三酰甘油、高密度脂蛋白胆固醇、糖化血红蛋白、血钙、TyG、AIP是老年CHD合并T2DM患者冠状动脉正性重构的危险因素(P<0.05,P<0.01)。多因素logistic回归分析显示,TyG(OR=7.253,95%CI:2.458~13.364,P=0.035)、AIP(OR=6.017,95%CI:2.205~12.025,P=0.030)是老年CHD合并T2DM患者冠状动脉正性重构的独立危险因素(P<0.05)。TyG、AIP预测老年CHD合并T2DM患者冠状动脉正性重构的曲线下面积分别为0.783、0.766,联合预测老年CHD合并T2DM患者冠状动脉正性重构的曲线下面积为0.868,显著优于单独预测(P<0.05)。结论TyG和AIP与老年CHD合并T2DM患者冠状动脉正性重构密切相关,可作为预测冠状动脉正性重构的有效指标,对临床早期识别高危患者及制定个体化干预策略具有重要意义。展开更多
