The transition temperatures detected by the Depolarized Light Intensity measurements were used to construct the phase diagram in which the influence of temperature was shown. The enhanced depolarized light intensity observed in the ternary system suggests that the coil polymer chains may tend to be extended and contribute to the overall anisotropy of the liquid crystal phase.展开更多
目的探究绝经后骨质疏松症合并2型糖尿病(osteoporosis and type 2 diabetes mellitus,OP-T2DM)的相关因素。方法选取武警福建省总队医院2019年1月—2021年12月收治的130例女性T2DM患者,开展骨密度检测,根据检测结果将其分成骨质疏松组(...目的探究绝经后骨质疏松症合并2型糖尿病(osteoporosis and type 2 diabetes mellitus,OP-T2DM)的相关因素。方法选取武警福建省总队医院2019年1月—2021年12月收治的130例女性T2DM患者,开展骨密度检测,根据检测结果将其分成骨质疏松组(108例)和非骨质疏松组(22例),分析绝经后T2DM群体中OP症的发生情况,对相关因素进行筛选及影响因素分析,包括血压、糖尿病病程、LDL-C、HDL-C、年龄、身高、BMI、绝经年限、合并糖尿病肾病。结果两组的年龄、BMI、绝经年限、合并糖尿病肾病相比,差异有统计学意义(P<0.05)。将其纳入到Logistic回归方程中,发现年龄、绝经年限、合并糖尿病肾病为T2DM患者引发OP的危险因素,BMI为保护因素(P<0.05)。结论绝经后T2DM群体中,OP发生与绝经年限、年龄、BMI以及合并糖尿病肾病有关。其中,BMI为保护因素,绝经年限、年龄、合并糖尿病肾病为危险因素。展开更多
