Ovine Iliac Vein Model for Endovascular Thrombectomy of Acute Deep Venous Thrombosis

An ovine iliac vein thrombosis model was devised to test a wall-contacting rotational thrombectomy device. Thrombosis was successfully induced in 9 sheep with an average clot length of 31 mm ± 12 and >60% vessel occlusion on angiography. The thrombus was subsequently removed, maintaining normal intraoperative pulmonary arterial pressure (5.9 mm Hg ± 3.6) and complete distal reperfusion after thrombectomy. Additionally, the sheep were without signs of vascular trauma or embolic complications on gross necropsy and histopathologic analysis. The findings from this study support the use of an ovine iliac deep vein thrombosis model for testing of a lower extremity thrombectomy device.     

1例重型弥漫性轴索损伤伴肺挫裂伤患者的肺康复护理

总结1例重型弥漫性轴索损伤伴肺挫裂伤患者的肺康复护理经验。护理要点包括：组建多学科肺康复管理团队,实施个性化呼吸支持与降阶梯序贯氧疗护理,精准廓清呼吸道,开展一体化的早期肺功能康复锻炼。经过多学科团队合作,患者入院后第12天撤离呼吸机,第17天拔除气管插管,第20天下床活动,第37天顺利出院,随访6个月,患者恢复良好。     

胶质淋巴系统——脑部疾病机制研究新方向

胶质淋巴系统是一个主要由星形胶质细胞水通道蛋白4介导的依靠动脉、静脉周围血管间隙的脑脊液-脑组织液交换流动的系统，是阿尔茨海默病、脑卒中、帕金森病、失眠、抑郁症等脑病的共同特征，是一条新的脑代谢途径，可以清除包括β-淀粉样蛋白、乳酸在内的代谢产物。本文综合分析了全球有关胶质淋巴系统在脑部疾病的研究，得出：胶质淋巴系统可能为神经退行性疾病等发病机制和诊治策略研究带来新视角；胶质淋巴系统有望为一些脑部疾病诊断提供新的有效证据；胶质淋巴系统可能是脑部疾病治疗给药方式的新途径。     

Case Report: Transient Stress Hyperglycemia in the Patient With ST-Elevation Myocardial Infarction

Transient stress hyperglycemia in the setting of acute myocardial infarction is a frequent phenomenon. Its transient nature should not dissuade the clinician from management of elevated blood glucose in a patient after an ST-elevation myocardial infarction. This case presents an adult patient after an ST-elevation myocardial infarction with transient stress hyperglycemia and the evidence used to identify optimal pharmacologic management and secondary prevention.
