简介:摘要目的探讨对比不同胰岛素(甘舒霖30R、诺和灵30R)对糖尿病的治疗效果。方法选取我院2015年9月-2016年9月收治的患有糖尿病的104例患者,对其采用数字抽签法分组,对照组给予甘舒霖30R治疗,观察组给予诺和灵30R治疗,比较其血糖控制效果和不良反应情况。结果两组患者血糖指标之间差异不明显(P>0.05),无统计学意义。两组患者不良反应发生率分别为1.9%、3.8%,没有差异和统计学意义(P>0.05)。结论糖尿病患者采用甘舒霖30R和诺和灵30R治疗的临床效果相似,不良反应发生率低,具有操作方便、注射次数少、安全、有效控制血糖等作用,值得在临床上使用。

简介:摘要r射线就是目前广为应用的一种工业生产设备,它可以实现对其他木材、塑料、瓷器、橡胶、金属等设备或零件的无损探伤检测,工作效率相当之高,可帮助人们快速发现设备或零件的内部缺陷,从而精确诊断故障部位、原因、性质、范围大小,评价设备或零件的质量。但r射线探伤机也具有其弊端,那就是对人的健康具有一定影响,如果长时间暴露在X射线的辐射当中,会使人的安全受到危害,因此我们在使用r射线探伤机的过程当中,同时还要注意对r射线辐射的防护与安全管理。本文基于作者自身的实际工作经验,首先简单介绍了r射线探伤机的工作原理与危害,然后主要就如何做好工业r射线探伤机的辐射防护与安全管理进行了探讨,以期能提高工业r射线探伤机在使用过程当中的健康与安全性。
