中国共产党在走过百年奋斗历程之际,提出“坚定历史自信”的命题,其主要目的在于激励全党踔厉奋发、勇毅前行,提醒全党不忘初心、牢记使命,引导全党抵制历史虚无主义。中国共产党坚定历史自信,强调历史自信与现实自信、未来自信的统一,既包括坚定对过去党史进程的自信、坚定对现实伟大实践的自信,也包括坚定对未来发展前景的自信。当前,中国共产党坚定历史自信具备充足的底气,科学理论的指导、历史成就的支撑、文化底蕴的积淀以及牢固的群众基础都是其历史自信的底气来源。未来中国共产党坚定历史自信必须以深化党史党建研究为本、以细化党史学习教育为基、以优化群众路线建设为要、以强化自我革命精神为重,在新的赶考之路上创造更辉煌的历史。

目的探讨认知-预警干预对农村糖尿病治疗延误患者认知行为的干预效果,旨在增进其治疗依从性。方法2019年10月—2020年1月便利选取黑龙江省大庆市大同区和河北省唐山市滦南县下属村的农村糖尿病治疗延误患者作为研究对象。按照随机数字表法选取试验组村和对照组村各6个,每组63例,试验组给予认知-预警干预,干预时间为2周,对照组给予常规的健康教育。通过一般情况调查表获得农村糖尿病治疗延误患者的一般人口学资料,使用农村糖尿病治疗延误认知行为量表、中文版Morisky服药依从性问卷及糖尿病管理自我效能量表评估干预前后认知行为、服药依从性和自我效能;通过采集静脉血收集空腹血糖水平。结果试验组和对照组最终各纳入60例,干预前两组的一般人口学资料、认知行为、服药依从性、糖尿病管理自我效能及空腹血糖水平均具有可比性。干预后试验组认知行为及服药依从性均高于对照组及干预前,差异均具有统计学意义(均P<0.05);试验组干预后糖尿病管理自我效能高于对照组,差异具有统计学意义(P<0.05);试验组干预后空腹血糖水平优于对照组,差异具有统计学意义(P<0.05)。结论认知-预警干预可以提高农村糖尿病治疗延误患者的认知行为水平,有助于增加农村糖尿病治疗延误患者的规范治疗。

目的探讨一种减少痔瘘手术患者术中出现血管迷走神经反射的护理方法。方法将200例行择期痔瘘手术患者随机分为实验组(100例)和对照组(100例);术中对照组接受常规护理,实验组在此基础上,手术全程予视听联合分散干预,即播放患者喜爱的影像音乐,分散注意力;观察、监测两组患者术中生命体征变化及出现血管迷走神经反射的例数分布。结果与对照组相比较,实验组患者接受视听分散干预后,术中生命体征相对平稳,出现血管迷走神经反射例数(2例)明显减少(对照组为9例),经统计学比较,差异有显著性意义(P<0.05)。结论对行痔瘘手术的患者,视听联合分散方式能有效减少术中血管迷走神经反射等不良应激反应的发生,稳定生命体征,可成为保障手术顺利实施的围手术期重要护理措施之一。
