肱三头肌反射新方法的探讨

<内科护理学>教材第三章护理体检中涉及到神经反射活动,实验项目之中就有引导肱三头肌反射.具体的实验步骤及检查方法为:受检者取坐位,检查者用左手托住受检者屈曲的肘部,右手持叩诊锤快速叩击其鹰嘴突上方约2 cm处的肱三头肌肌腱.正常反应为肱三头肌收缩,肘关节伸直,前臂稍伸展.检查时注意事项:消除受检者紧张情绪,转移其注意力,促使其肢体放松,即检查时受检者肢体肌肉应尽量放松;叩击肌腱的部位,应准确,叩击的力量轻重要适度,并注意双侧对比.     

应用ISO9000质量体系进行医疗设备管理的探讨

本文以如何做好新形势下医疗设备的管理工作为议题,简述了ISO9000质量控制体系的特点,论述了ISO9000体系对医疗设备管理的适宜性和必要性,并针对医院的设备管理特点,阐述了医院设备管理引进ISO9000体系需要注意的几个环节和实施ISO9000体系的效果.     

利用ISO9000族质量控制体系改造一次性医疗用品管理流程

一次性医疗用品的管理是一个多部门协作、多环节连续的过程。其管理模式存在着管理环节的不连贯性、管理制度的非标准性、工作方式的随意性、个人责任的不明确性和实施记录的非系统性等5个缺陷特征。针对这些问题引入了ISO9000动态的、具备防错与纠错功能的、保证质量管理水平螺旋式不断上升的体系。通过系统性的溯源。找出原因，并实施有效的纠正，防止差错的重复发生。新的管理流程重点突出了对过程管理的特点。确定一次性医疗用品管理的整体预期目标，实施预期目标的分段管理。重点加强对流程各个环节实施过程的管理，实现整个流程的优化和持续改进。强调质量记录，保持和实现流程过程各个环节的可追溯性。     

危重症患者血清降钙素原测定对细菌感染的诊断价值

Objective To evaluate the clinical value of serum procalcitonin (PCT) in the diagnosis of bacte-rial infections in the critically ill patients. Methods A loud d 100 cases of critical patients were divided into bacteri-al infection group(56 cases) and non-bacterial infection group(44 cases). Serum PCT was measured by immunolu-minometric assay. Results The concentration of PCT in bacterial infection group(21.54 ±5.72) μg/L, was signifi-cantly higher than non-bacterial infection group (11. 95±4. 58)μg/L (t =2.291,P<0.05);The APACHE Ⅲ score of bacterial infection group(62. 44 ± 19. 55) cent was significantly higher than non-bacterial infection group(44. 56 ± 25. 88) cent(t = 2. 195 ,P < 0. 05). The concentration of PCT of 1.0μg/L and 2. 0 p.g/L compared to the former sensitivity (96. 5) % higher than the latter (55.2) % (X2 = 3. 94, P < 0. 05), the former specificity (41.7) % lower than the latter (95.8)% (X2 = 4. 02 ,P < 0. 05);1.5μg/L as a positive standard Youden index and the Agreement (83.0 % ,0. 65), were significantly higher than 1 μg/L and 2 μg/L(71.7%, 0. 38 ;73.6% ,0. 51) (X2 = 3.84, X2=3. 90,X2 = 3.992 = 3.91 ,P < 0. 05);The concentration of PCT in death group (38. 9 ±12. 6)μg/L was signifi-canfly higher than the survival group(11.8± 8. 3) μg/L(t =2. 398 ,P <0. 05). Conclusion Serum PCT has clinical values in the diagnosis and therapy of bacterial infections in the critical patients.     

不同刺激强度电针对糖尿病胃轻瘫大鼠胃肠运动功能及胃窦平滑肌Ras同源物基因组成员A/相关卷曲螺旋蛋白激酶信号表达的影响

目的:观察不同刺激量电针腧穴对糖尿病胃轻瘫(DGP)大鼠Ras同源物基因组成员A(RhoA)/Ras同源物相关卷曲螺旋蛋白激酶(ROCK)信号表达的影响,探讨刺激量是否为腧穴配伍效应的影响因素。方法:SD大鼠随机分为空白组、模型组、小刺激量组、中刺激量组、大刺激量组,每组12只。采用单次腹腔注射2%链脲佐菌素配合高脂高糖饮食喂养8周建立DGP大鼠模型。分别采用0.12mA、0.24mA、0.36mA对小刺激量组、中刺激量组、大刺激量组电针"足三里""梁门""三阴交",每次20min,每日1次,连续15d。治疗后,酚红染色观察大鼠胃排空率及小肠推进率;免疫组化、Western blot法检测胃窦平滑肌组织RhoA、ROCK、肌球蛋白磷酸酶靶亚单位1(MYPT 1)、磷酸化MYPT 1(p-MYPT 1)蛋白的表达水平。结果:与空白组比较,模型组大鼠血糖明显升高(P0.05);胃排空率、小肠推进率和胃窦平滑肌组织RhoA、ROCK、MYPT 1、p-MYPT 1蛋白表达水平明显降低(P0.05)。与模型组比较,小、中、大刺激量组的胃排空率、小肠推进率和胃窦平滑肌组织RhoA、ROCK、MYPT 1、p-MYPT 1蛋白表达水平明显升高(P0.05)。与大刺激量组比较,小刺激量组胃窦平滑肌组织RhoA、ROCK、MYPT 1、p-MYPT 1蛋白表达水平明显降低(P0.05)。结论:电针治疗能通过上调RhoA/ROCK信号的表达有效促进胃平滑肌收缩,改善糖尿病胃轻瘫的症状,且大刺激量电针上调RhoA/ROCK信号的效果优于小刺激量,因此不同的刺激量可能是影响腧穴配伍效应的因素之一。     

手术室护士锐器伤现况调查与对策
