急性心肌梗塞猝死的诱因及抢救(附13例报告)

本文报告了急性心肌梗塞猝死13例。分析猝死的诱因主要有血清钾浓度降低,严重心律失常,包括室内传导阻滞、室性并行心律、室性早搏等。近年来急性心肌梗塞的发病率日趋增高,心源性猝死也随之增多,有必要对猝死的诱因进行探讨,以采取有效的抢救措施。     

Enhancement of hepatic hemangiomas with levovist on coded harmonic angiographic ultrasonography.

OBJECTIVE: To evaluate the pattern of contrast enhancement with Levovist on coded harmonic angiographic ultrasonography of hepatic hemangiomas. METHODS: Twenty hemangiomas were evaluated with coded harmonic angiographic ultrasonography and a microbubble contrast agent. Verification of the diagnosis of a hemangioma was made by means of dynamic computed tomography (n = 8), dynamic magnetic resonance imaging (n = 1), radionuclide scanning (n = 6), or follow-up ultrasonography (n = 5). Ultrasonographic images were obtained before contrast agent administration and with a bolus injection of 2.5 g of a microbubble contrast agent (300 mg/mL Levovist; Schering AG, Berlin, Germany) every 10 to 15 seconds for 5 minutes. The contrast enhancement patterns of the 20 hemangiomas were assessed. RESULTS: The tumor diameters as measured on ultrasonography were 7 to 97 mm (mean, 26.7 mm). Of the 20 hemangiomas, peripheral globular enhancement with progressive centripetal fill-in was shown in 15 (75%), rimlike enhancement with progressive centripetal fill-in was shown in 2 (10%), and homogeneous enhancement was shown in 1 (5%). In the remaining 2 lesions (10%), the enhancement patterns could not be seen, because they were not found on coded harmonic angiographic ultrasonography. CONCLUSIONS: Coded harmonic angiographic ultrasonography with a microbubble contrast agent can depict the typical enhancement pattern in most hepatic hemangiomas.

健康教育在糖尿病病人中的应用

目的：通过对患者在住院过程中的系统教育，使患者了解自己疾病的知识，提高患者对糖尿病的认知水平和自我管理能力，养成良好的健康行为和生活方式，从而提高生活质量。方法：采用集体、个体、自学等形式进行教育。结果：通过培养，患者掌握了一些基本的操作技能，明显缩短了住院日，同时激发了护士与患者学习专业知识的热情，减少或延缓了并发症的发生。结论：①健康教育是一个护患双边活动过程。②通过教育，可不断提高护士的自身修养和专业知识水平。③健康教育是糖尿病患者学习糖尿病知识，提高自我护理能力的有效途径。     

生物化学与细胞生物学课程整合的探讨

为了适应新世纪教学内容和课程体系改革的要求,我校借鉴美国哈佛大学医学院的经验,将生物化学与细胞生物学两门课程整合为“细胞的化学与生物学”。整合后在减少两个学科间重复内容、增加学科间联系、减少学时、早期接触临床、培养学生分析解决问题的能力、创新能力等方面有了很大改进,为这两门课程的改革开辟了新途径。     

Intracapsular implant rupture: MR findings of incomplete shell collapse

The objective of this study was to determine the frequency and significance of the MR findings of incomplete shell collapse for detecting implant rupture in a series of surgically removed breast prostheses. MR images of 86 breast implants in 44 patients were studied retrospectively and correlated with surgical findings at explanation. MR findings included (a) complete shell collapse (linguine sign), 21 implants; (b) incomplete shell collapse (subcapsular line sign, teardrop sign, and keyhole sign), 33 implants; (c) radial folds, 31 implants; and (d) normal, 1 implant. The subcapsular line sign was seen in 26 implants, the teardrop sign was seen in 27 implants, and the keyhole sign was seen in 23 implants. At surgery, 48 implants were found to be ruptured and 38 were intact. The MR findings of ruptured implants showed signs of incomplete collapse in 52% (n = 25), linguine sign in 44% (n = 21), and radial folds in 4% (n = 2). The linguine sign perfectly predicted implant rupture, but sensitivity was low. Findings of incomplete shell collapse improved sensitivity and negative predictive values, and the subcapsular line sign produced a significant incremental increase in predictive ability. MRI signs of incomplete shell collapse were more common than the linguine sign in ruptured implants and are significant contributors to the high sensitivity and negative predictive values of MRI for evaluating implant integrity.
