目的分析左西孟旦在急性心肌梗死(AMI)合并心力衰竭患者中的应用效果。方法选取2018年1月至2022年11月北京市大兴区人民医院收治的106例AMI合并心力衰竭患者作为研究对象,按照随机数字表法将其分为两组,各53例。对照组采用标准化治疗,观察组同时联合左西孟旦治疗。比较两组治疗前后血清炎症因子[超敏C反应蛋白(hs-CRP)、白细胞介素-6(IL-6)、肿瘤坏死因子-α(TNF-α)]、血流动力学水平[心指数(CI)、全心舒张末容积指数(GEDVI)、全身血管阻力指数(SVRI)]、心功能指标[左室射血分数(LVEF)、每搏输出量(SV)、B型尿钠肽(BNP)],及临床疗效和不良反应总发生率。结果治疗后,两组hs-CRP、IL-6、TNF-α、GEDI、SVRI、BNP水平均低于治疗前,且观察组低于对照组(P0.05)。结论标准化治疗基础上联合左西孟旦治疗AMI合并心力衰竭能够有效缓解患者的炎症反应,稳定血流动力学,改善心功能和临床疗效,且无明显不良反应。

为探究线型SBS改性沥青老化过程中流变特性的演化与微观结构的变化机理,采用频率扫描试验、流变主曲线、多重应力蠕变回复试验(MSCR)及傅里叶变换红外光谱试验(FT-IR)分别分析线型SBS改性沥青在不同时程老化程度下多温度域的流变特性及官能团变化.研究表明,采用相位角频率扫描(75、65、55℃)或第一次循环J_(nr)3.2离散率指标,可以将线型SBS改性沥青的老化分为初期、中期、后期3个阶段,不同的阶段呈现不同的流变特征.聚丁二烯指数与线型SBS改性沥青老化初期和中期的相位角主曲线平台区临界点有较好的线性相关性.

小儿腹泻为临床常见疾病,发病原因包括病毒感染、细菌感染及非感染性三种,严重者出现重度水电解质及酸碱平衡紊乱,并伴全身中毒症状,威胁患儿生命安全。在对其治疗中,多以西药治疗为主,常见治疗方式包括蒙脱石散、益生菌、锌制剂等,近年来中医特色治疗(中药、针刺等)、理疗方案应用频率逐渐增加,分别通过调节患儿肠道运动功能、消除消化道黏膜炎症反应,通过联合治疗以保证临床价值,但目前在对该病治疗中尚缺乏标准化治疗方案,仍需深入研究。
