管道风险评估表在心内科监护室的应用

目的 探讨管道风险评估表在预防心内科置管患者导管滑脱的应用效果.方法 将276例带多种管道患者随机分为对照组136例和观察组140例,对照组采用常规方法进行护理,观察组使用管道风险评估表评估患者并根据风险分级进行预见性护理,比较两组患者管道滑脱率及管道安全事件发生率.结果 观察组患者管道总脱落率为2.26％,对照组为11.73％,两组比较差异有统计学意义（Z=-4.831,P=0.000）;观察组患者发生管道安全事件发生率为6.48％,对照组发生率为25.23％,组间比较差异有统计学意义（x2=-49.632,P=0.000）.结论 应用管道风险评估表能最大程度降低管道脱落风险,提高了心内科护士风险识别和处理能力.     

Question mark ears and post-auricular tags

Questions mark ears are an easily recognisable but uncommon malformation of the external ear. They can be found as an isolated malformation and are a pathognomonic sign of the auriculo-condylar syndrome. An additional unique sign in this syndrome may be present in the form of post-auricular tags. Such malformations should prompt further investigation for other signs of the auriculo-condylar syndrome.

Treatment of complex intracranial pathologies with transcirculation endovascular approaches

ObjectThe breadth and complexity of neurovascular pathologies treated with endovascular neurosurgery has expanded dramatically in recent years. Many aneurysms remain difficult to treat safely. Transcirculation (contralateral and/or retrograde) approaches through the circle of Willis are useful alternatives for treating challenging lesions endovascularly. Here, we present a series of patients treated with unconventional transcirculation techniques.MethodsA total of six patients were treated: four patients with five aneurysms, one patient with an MCA stroke, and one patient with a meningioma requiring preoperative embolization were initially thought not to be amenable to endovascular treatment. The decision was made to treat these patients with transcirculation approaches. All patients were treated by one interventionist. One aneurysm was located in the cavernous internal carotid artery (ICA), one in the vertebral artery, two in the paraclinoid ICA, and one in a cerebellar AVM feeder vessel were treated.ResultsFive of six patients (83%) made a full neurologic recovery. Three aneurysms were treated to complete occlusion, one aneurysm was left with small residual neck filling, and one aneurysm was not able to be treated. One patient underwent mechanical thrombectomy of a middle cerebral artery (MCA) embolus and MCA filling was restored after treatment. One patient underwent complete embolization of the deep vascular supply of a meningioma.ConclusionsAlthough many neurovascular pathologies remain unsuitable for endovascular treatment, transcirculation approaches can allow for safe, successful treatment of challenging lesions in select patients.     

任意分组标记法在cDNA微阵列图像分析中的应用

获取cDNA微阵列点的颜色数据，是实现cDNA微阵列图像分析的基本前提，cDNA微阵列的构成是多种多样的，主要表现在具有不同的点阵密度和不同的分布形状等方面，通用、方便和快捷的数据点颜色值获取方法，将有助于扩大计算机分析系统的数据处理速度和应用范围，本文介绍了任意分组标记法的基本原理及其在cDNA微阵列图像分析系统中的应用。     

管道护理在IABP患者非计划性脱管和拔管中的价值

目的：探讨管道护理在主动脉内球囊反搏患者非计划性脱管和拔管中的价值。方法方便选择2013年6月—2015年9月该院收治的冠心病需要行IABP治疗患者80例,按照随机数字法分为两组,各40例,观察组实施该研究护理干预方法,对照组实施常规护理,比较两组非计划性脱管及拔管比例及两组IABP治疗时间及因导管问题引起死亡情况。结果观察组发生非计划性脱管﹑拔管的比例分别为2.5%和2.5%,均显著低于对照组的22.5%和25.0%差异有统计学意义(P<0.05),观察组IABP治疗时间为(128.6±25.1)h,长于对照组的(103.5±23.3)h,差异有统计学意义(P<0.05),治疗后因导管问题引起死亡例数为1例,比例为2.5%,显著低于对照组的9例,22.5%,差异有统计学意义(P<0.05)。结论有效的护理干预能提高主动脉球囊反博治疗患者临床治疗效果,减少非计划性脱管﹑拔管比例。     

Saliva from cheese bite yields DNA profile of burglar: a case report

Physical evidence in the form of a high quality bite mark was discovered on a piece of yellow cheese found at the scene of a crime. The cheese had been frozen by police for 10 days after recovery and before submission to the laboratory for testing. The double swab technique was used to collect DNA samples. A sample of the suspect’s blood was obtained. Using PCR-based DNA typing at ten STR loci, (Profiler Plus, Perkin Elmer-Applied Biosystems) it was determined that the DNA from the cheese originated from the suspect. This case illustrates the importance of a) always considering human bite marks as both physical and biological evidence, and b) attempting DNA recovery in any case in which minute traces of saliva may be present, even in situations involving bacteria-rich foods.
