目的 探讨肾移植患者发生全麻苏醒期高血压危象的影响因素。方法 回顾性分析2019年9月—2021年9月期间吉林大学第一医院进行的98例急诊同种异体肾移植手术的临床资料。根据麻醉苏醒期的血压分为高血压危象组(49例)和血压稳定组(49例),对比两组的临床资料并分析肾移植患者发生全麻苏醒期高血压危象的影响因素。结果 高血压危象组与血压稳定组相比,前者平均年龄较大、BMI值较高、受体存在原发性高血压的比例较大、高血压脑出血供肾的比例较大、T1和T2时的收缩压较高 ...

Deep quantile regression for growth and maturation reaction norms
Abstract Understanding species' growth and maturation responses to anthropogenic and environmental pressures is crucial for tracking demographic shifts, phenotypic change and ensuring population sustainability. Traditional regression methods often focus on modelling the conditional mean of life‐history traits, potentially overlooking heterogeneity in ...

本文用扫描电镜观察了经伊文思兰染的五周龄、五月龄和一年龄三个不同年龄组莱亨鸡受高脂血症分别影响4周和8周后主动脉内皮发生的形态变化。实验显示各年龄正常血脂组伊文思兰染区已出现内皮浅表性损伤。高血脂组兰染区内皮出现多发性“园球状隆起”性病灶,其实质是内皮细胞高度肿胀与泡沫样变性。一年龄组内皮泡沫样变性发生时间慢于另两个年龄组,提示幼年动物内皮比成年动物更易受高脂血症的作用而迅速发生泡沫样变性。内皮表面在正常血脂与高脂血症时,都有单核细胞粘附,但在高脂血症时单核细胞较活跃并可见插于内皮细胞间 ...

目的考察不同年龄段人群动脉粥样硬化(AS)相关危险因素水平及其致病风险。方法以2016年1月至2019年1月我院收治的AS相关疾病住院患者4089例为研究对象,分为中年组、老年组和高龄老年组。根据血管造影、CT血管成像或外周血管超声检查确立AS诊断。结果①年龄越大,动脉血管严重病变的比例越高。②高血压病、糖尿病的患病率均以老年组最高,显著高于中年组。③肥胖、血脂异常、吸烟、饮酒则是中年组最高,高龄老年组最低 ...

【目的】探讨自发高血压大鼠心肌肥厚与心室颤动阈值的关系。【方法】20只雄性自发高血压大鼠,随机分成10周龄组(n=10)和18周龄组(n=10);10只10周龄雄性Wistar大鼠为对照组。分别测定3组大鼠的动脉收缩压、心脏质量指数、心室有效不应期和心室颤动阈值。【结果】①自发高血压大鼠的动脉收缩压和心脏质量指数明显高于Wistar大鼠(P〈0.001),心室颤动阈值明显低于Wistar大鼠(P〈0.001);②自发高血压大鼠中 ...
