医护患协同合作模式对原发性高血压患者服药依从性和血压控制的影响

目的探讨医护患协同合作模式对原发性高血压患者服药依从性和血压控制的影响。方法选取2018年1—9月在四川省第四人民医院住院的280例高血压患者,按随机数字表法分为对照组和观察组。对照组采用常规治疗护理措施,观察组采用医护患协同合作模式进行管理。比较两组患者干预6个月后服药依从性和血压控制情况。结果观察组服药依从性、血压控制效果均优于对照组,差异有统计学意义(P<0.05)。结论医护患协同合作模式可明显改善原发性高血压患者的服药依从性,有效控制血压,提高患者生存质量,促进社会和谐,值得临床推广应用。

DYNAMIC CHARACTERISTICS ON PRECISION NC LATHE BASED ON MULTI-BODY SYSTEM THEORY

Based on multi-body system theory and the mainshafl system of precision NC lathe as object investigated, it is treated as a coupled rigid-flexible multi-body system which is made up of some rigid and elastic bodies in an especial linking mode. And a dynamic model is established, The problems of computing vibration characteristics are resolved by using multi-body system transfer matrix method, Resutts show that the mainshaft system of NC lathe is in the stable and reliable working area all the time. The method is simple and easy, the idea is clear. In addition, the method can be easily used and popularized in the other multi-body system.

Fe掺杂TiO2纳米材料的合成及光催化性能

以钛酸丁酯为钛源,Fe(NO3)3·9H2O为铁源,采用溶胶-凝胶法制备Fe/TiO2纳米粉体,利用溶胶结合静电纺丝技术制备Fe/TiO2纳米纤维,从材料改性及形貌改善两个角度共同提高TiO2纳米材料的光催化活性及实用性。借助XRD、SEM、TEM等分析技术,探究了Fe/TiO2纳米材料在可见光区的光催化活性,分析了煅烧温度及掺铁量对Fe/TiO2纳米材料光催化性能的影响。结果显示,铁的掺入及形貌的改善有助于提高TiO2的光催化性能。
