超声引导结合X线透视下PTCD治疗阻塞性黄疸

目的探讨超声引导结合X线透视下PTCD的操作技术及其临床应用价值。方法51例阻塞性黄疸患者,40例为恶性阻塞性病变,11例为良性阻塞性病变,在超声引导结合X线透视下行PTCD术,穿刺右叶胆管44例,穿刺左叶胆管7例,并常规造影。结果穿刺成功率100%,未出现出血、胆汁性腹膜炎等并发症。术后1周胆红素平均下降75.2ummol/L。结论超声引导结合X线透视下PTCD是一种治疗阻塞性黄疸的有效方法,具有安全、简便、经济、并发症少的优点。     

Malignant Rhabdoid Tumor of the Breast: A Case Report

A 66-year-old woman time of 10 days. One month after radicalmastectomy, there was local recurrence, followed by multiplepulmonary metastases, and the patient died of respiratory failure5 months after surgery. The gray-white-colored tumor measured13x12x;10 cm, and its border was well defined. The tumor wascomposed of diffusely growing round or polygonal cells withvesicular nuclei, prominent nucleoli, and ample cytoplasm containingeosinophilic inclusions. Lymph node involvement was widespread.Both vimentin and keratin were clearly demonstrated by immunohistochemicalstaining. Ultrastructural studies revealed that the MRT cellscontained cytoplasmic whorls of intermediate filaments.     

前列腺素E1治疗慢性乙型肝炎黄疸的观察

目的观察前列腺素E1治疗慢性乙型肝炎重度黄疸的疗效。方法在综合治疗基础上，分别使用前列腺素E1（治疗组）和门冬氨酸钾镁（对照组）治疗慢性乙型肝炎重度黄疸患者各35例，并观察其症状、体征及肝、肾功能等，疗程4周。结果治疗组的症状、体征及肝功能指标及总有效率，均显著优于对照组，两组比较差异有显著意义（P〈0．05）。结论前列腺素E1治疗慢性乙型肝炎重度黄疸能显著地促进黄疸消退和改善肝功能。     

软组织恶性纤维组织细胞瘤临床CT分析

目的探讨软组织恶性纤维组织细胞瘤(MFH)的临床和CT表现特点。资料与方法回顾性分析经手术病理证实的12例MFH的临床和CT表现。结果12例中9例为复发病例,复发病程平均5.06个月。12例中2例为2处病灶,14个病灶中发生于四肢者9个(64.29%)。CT像上病灶境界不清,呈浸润性生长,具有侵犯邻近组织等恶性肿瘤的生物学特性。结论MFH的临床和CT特征性表现对其诊断和治疗有一定的指导意义。     

The effect of oral appliance therapy on blood pressure in patients with obstructive sleep apnea

The objective of the study was to investigate the effects of oral appliance (OA) therapy on ambulatory blood pressure in patients with obstructive sleep apnea (OSA). Eleven OSA patients who received OA therapy were prospectively investigated. Ambulatory blood pressure was measured for 20 h from 4:00 p.m. to 12:00 noon the next day using an ambulatory blood pressure monitor. The Respiratory Disturbance Index (RDI) was measured in the pretreatment and posttitration periods. The OA was titrated to reach a therapeutic jaw position over 2 to 8 months, and posttitration measurements were repeated. At posttitration, the RDI was significantly decreased from a mean (SD) of 24.7 (20.1) to 6.1 (4.5). Significant reductions in diastolic blood pressure (DBP) and mean arterial pressure (MAP) were found for the 20-h periods, and systolic blood pressure (SBP), DBP, and MAP while asleep. The mean values were 79.5 (5.5) to 74.6 (6.0) for DBP and 95.9 (5.4) to 91.2 (5.9) for MAP, for over a 20-h period, and 118.4 (10.0) to 113.7 (9.1) for SBP, 71.6 (8.0) to 67.2 (7.9) for DBP, and 88.4 (8.0) to 83.9 (7.5) for MAP, while asleep. This study suggests that successful OSA treatment with an OA may also be beneficial to lower blood pressure in OSA patients, as previously suggested for nasal continuous positive airway pressure therapy. This study was conducted in the Division of Orthodontics, The University of British Columbia, Canada     

植入式心律转复除颤患者的护理及随访

目的总结植入式心律转复除颤器(ICD)安置术的护理。方法2001年7月~2004年6月给予13例ICD患者进行了护理及随访。结果术后有2例患者出现心律失常“风暴”,经处理后未再出现心室颤动。随访患者1~4年,均存活,未发生晕厥等并发症。结论术前重视患者的心理护理,术后密切观察病情,积极预防心律失常“风暴”,并做好ICD健康教育,是ICD手术成功的重要护理措施。     

高血压合并阻塞性睡眠呼吸暂停的短期血压变异性研究

目的 比较高血压合并阻塞性睡眠呼吸暂停患者的短期血压变异性。方法 将155例分为对照组、高血压组、高血压合并轻度或中重度阻塞性睡眠呼吸暂停组，EE较患者不同活动状态的短期血压变异性。结果 高血压合并中重度阻塞性睡眠呼吸暂停组患者睡眠期间和早晨血压变异系数分别为：收缩压18．69、21．32；舒张压19．41、23．61，明显高于其他各组。结论 夜间睡眠期间和早晨短期血压变异性增加，是高血压合并中重度阻塞性睡眠呼吸暂停患者夜间和早晨心血管事件发生率增加的重要危险因素。     

Detection of Epstein Barr virus in an hepatic leiomyomatous neoplasm in an adult human immunodeficiency virus 1-infected patient

We report the first case of a human immunodeficiency virus (HIV)-related primary hepatic leiomyoma in an adult patient. The diagnosis was made at autopsy and confirmed by immunohistochemistry. Epstein Barr virus (EBV) was identified in tumour cells by in situ hybridization. Review of the literature revealed 13 cases of visceral myogenic tumours occuring in acquired immunodeficiency syndrome children, and only 2 cases in adults. One was a spinal epidural leiomyoma, the other multiple smooth muscle tumours of the colon and adrenal gland. This is the first report of EBV in smooth muscle neoplastic cells in an HIV-infected adult patient.
