简介:目的探讨甲型H1N1流感并肺炎的CT表现。方法5例临床确诊甲型H1N1流感的重症患者共8次胸部CT扫描(复查3例)资料。结果5例中均为双肺多叶、多段实变灶,无明显肺叶、肺段或特定体位分布趋势;大片肺实变表现为双侧沿支气管树分布的肺段实变;内有明显的空气支气管征;相邻肺段实变融合或在叶间裂处相邻的肺叶实变扩展,于影像接触部位融合,形成更大片实变影;肺内小病灶均为双肺多发,呈类圆形或棉团状,沿肺纹理分布最多见;大片肺实变可呈均匀致密实变、磨玻璃样变、蜂窝状实变,小病灶与大片实变灶一致,磨玻璃样变可出现在初诊和吸收期病例;反应性胸膜增厚及胸膜积液常见;无纵膈、肺门淋巴结肿大。结论CT改变提示:甲型H1N1重症病例并肺炎在病程发展阶段,病变有经支气管肺泡系播散的特点。
简介:【摘要】目的:研究并分析 1 例 1 型糖尿病伴酮症酸中毒患儿的护理工作 。方法:将 2019 年在我院入院治疗的 1 例 I 型糖尿病酮症酸中毒患儿纳入到本组研究中,对其临床治疗、护理工作个案进行回顾、分析。 结果:通过医护人员的共同护理与患儿、家属的配合,通过降糖、补液、纠正电解质酸碱平衡紊乱、灭酮、饮食指导、运动指导、心理护理等方式,患儿好转,顺利出院,出院时,血糖控制效果理想,酮体转为阴性。 结论: 1 型糖尿病伴酮症酸中毒 患儿在一经确诊后,要及时抢救、迅速补液,纠正电解质紊乱、酸中毒等,采用科学的治疗和护理干预方法,监测患儿指标变化,促进其顺利康复。
简介:胃癌是导致癌症患者死亡的主要疾病之一,而现有的治疗手段有限。当前免疫检测点抑制剂在肿瘤的治疗中取得了突破进展,相关研究迅速覆盖到胃癌。针对免疫检查点抗程序性死亡分子1(PD-1)/PD-1配体(PD-L1)抗体的临床研究正在广泛开展。本文对胃癌发生的免疫机制,PD-1/PD-L1表达,抗PD-1/PD-L1抗体早期临床研究及抗PD-1/PD-L1抗体预测疗效的生物标志物的研究进行文献复习。
简介:AbstractStroke is a devastating disease that occurs when a blood vessel in the brain is either blocked or ruptured, consequently leading to deficits in neurological function. Stroke consistently ranked as one of the top causes of mortality, and with the mean age of incidence decreasing, there is renewed interest to seek novel therapeutic treatments. The Scavenger Receptor Class B type 1 (SR-B1) is a multifunctional protein found on the surface of a variety of cells. Research has found that that SR-B1 primarily functions in an anti-inflammatory and antiatherosclerotic capacity. In this review, we discuss the characteristics of SR-B1 and focus on its potential correlation with the modifiable risk factors of stroke. SR-B1 likely has an impact on stroke through its interaction with smoking, diabetes mellitus, diet, physical inactivity, obesity, hypercholesterolemia, atherosclerosis, coronary heart disease, hypertension, and sickle cell disease, all of which are critical risk factors in the pathogenesis of stroke.
