简介:摘要目的通过建立了PICC患者微信群,患者就PICC家庭维护出现的问题,通过图片、文字等多种方式向护士咨询,护士及时指导,通过微信群的平台,大大降低了导管并发症的发生。方法由科室护士长设立微信群,护士长、有资质置管护士及PICC置管患者共同参与加入微信群。结果微信圈凭借着自身强大的优点,现已被人们广泛使用。患者通过微信,护士可以及时给予患者指导,大大降低了并发症的发生。护士也经常在微信群中发布一些PICC导管相关知识,患者通过阅读,提高了自我家庭护理能力。患者觉得科室对患者负责,自认而然对护士的满意度也随之提高了。结论在信息化时代的今天,微信使护患双方紧密地联系在了一起,增加交流沟通的同时,也在现代医学护理中发挥了更大作用。

简介:目的探讨广谱氯离子通道阻滞剂4,4’-二异硫氰基芪-2,2’-二磺酸(DIDS)对大鼠缺血再灌注损伤心肌细胞凋亡的影响及其机制。方法雄性SD大鼠36只随机分为3组:缺血再灌注组(A组)、DIDS处理组(B组)和LY294002预处理组(C组)。伊文兰和TTC染色测定心肌梗死范围,TUNEL方法定性和定量检测心肌细胞凋亡指数,Westernblot测定蛋白激酶B(Akt)的表达。结果与A组比较,B组心肌梗死范围和心肌细胞凋亡指数明显降低[(38.8±7.7)%”(54.2±10.8)%,(8.9±1.8)%”(17.6±3.5)%.P〈0.01];磷酸化Akt表达水平明显增加(P〈0.01)。与A组比较,C组梗死面积、凋亡指数无明显减小,磷酸化Akt水平无明显变化(P〉0.05)。结论DIDS能够抑制大鼠缺血再灌注所致的心肌细胞损伤,可能是通过信号分子磷脂酰肌酶三羟基激酶/Akt的调节。

简介:目的:观察探讨普伐他汀(pravastatin)与脉通的临床疗效.方法:70例高脂血症患者,随机分为2组:普伐他汀组36例,男20例,女16例,采用普伐他汀5~10mg,1次/d,共6个月;脉通组34例,男18例,女16例,采用脉通1粒,1次/d,共6个月.结果:普伐他汀降低TC、TG水平,升高HDL水平的总有效率分别为90.9%,55%及91.7%;脉通降低TC、TG水平,升高HDL水平的总有效率分别为3.2%,5.2%及11.1%;两组比较有非常显著差异(P<0.01).普伐他汀组有4例出现一过性ALT水平升高.结论:普伐他汀为安全有效的降脂药.

简介:目的中国汉族人群中SCN5A基因A1673G多态与孤立阵发房颤的相关性。方法选取汉族孤立阵发房颤患者120例为观察组,以健康汉族人群120例为对照组,采用限制性片段长度多态性分析(RFLP),对SCN5A基因A1673G的多态位点进行基因型鉴定,并随机挑选样本进行测序,检验其可靠性。结果SCN5A基因A1673G多态位点在中国汉族人群孤立阵发房颤患者和正常组比较,基因型频率符合Hardy-Weinberg平衡定律;A1673G多态的基因型频率在两组间差异有统计学意义(P〈0.05),房颤患者G等位基因高于正常组;GG基因型对房颤患者有明显影响(P〈0.05)。结论SCN5A基因变异可能与中国汉族人群孤立阵发性房颤相关。
