沙库巴曲缬沙坦在心力衰竭治疗中的应用

心力衰竭是一种慢性疾病，是心脏无法泵出足够的血液为其他身体器官提供氧气，从而引发呼吸短促、疲劳和水肿等症状。目前其治疗包括病因治疗、一般治疗、药物治疗及非药物治疗等，其中血管紧张素受体脑啡肽酶抑制剂（ARNI）是当前新研发出的一类抗心衰药物，沙库巴曲缬沙坦是其代表药物，具有阻断肾素-血管紧张-醛固酮系统（RAAS）及抑制脑啡肽酶（NEP）的双重作用，新的欧美指南均推荐用于射血分数降低心力衰竭（HFrEF）的治疗。本文现就沙库巴曲缬沙坦在心力衰竭治疗中的作用机理、临床试验、药物安全性作一综述，旨在为该病的临床治疗提供参考。     

Lung Ultrasound for the Emergency Diagnosis of Pneumonia,Acute Heart Failure,and Exacerbations of Chronic Obstructive Pulmonary Disease/Asthma in Adults: A Systematic Review and Meta-analysis

Background

Lung ultrasound can accelerate the diagnosis of life-threatening diseases in adults with respiratory symptoms.

A case of acute heart failure associated with Guillain-Barré syndrome

Abstract Guillain-Barré syndrome (GBS) is a disease of the peripheral nervous system, which is caused by aberrant immune responses directed against some components of peripheral nerves. GBS is rarely accompanied by cardiovascular involvement. We describe a case of acute neuropathy complicated by sudden heart failure and left ventricular dysfunction which had a presumably neurogenic origin. Pathogenesis of acute heart failure is probably due to transitorial stunned myocardium and neurogenic cardiac injury. We show a rare case of transitorial and acute cardiac dysfunction by echocardiography and laboratory markers of heart failure.     

透析液钙离子浓度对肾功能衰竭血液透析患者血清钙离子水平及血压的影响

目的 观察不同钙离子浓度的透析液对血液透析患者透析后血清钙离子水平及血压变化的影响，为肾功能衰竭血液透析患者的高钙血症及高血压的防治提供依据。方法 选择不同钙离子浓度的透析液，将维持性血液透析患者分为高钙组（1．75mmol／L）和低钙组（1．25mmol／L），比较患者每次透析前后脉搏、血压，同时抽查患者透析前后血钙及血肌酐浓度的变化。结果透析后两组患者血肌酐浓度均显著下降，透析前后差异均具有统计学意义（P〈0．01）；高钙组患者透析后血钙较透析前升高，差异具有统计学意义（P〈0．01），而低钙组患者血钙比透析前略降低，差异无统计学意义（P〉0．05）。高钙组患者透析后较透析前收缩压、舒张压及平均动脉压都升高，差异均具有统计学意义（P〈0．05），而低钙组患者透析后较透析前收缩压、舒张压及平均动脉压都降低，差异均具有统计学意义（P〈0．05）。透析后两组血钙比较差异具有统计学意义（P〈0．01）；透析后低钙组较高钙组患者的收缩压、舒张压及平均动脉压都降低，三者差异均具有统计学意义（P〈0．01）。结论透析液钙离子浓度与血液透析患者血清钙离子水平及血压呈正相关，低钙透析液透析有助于维持性血液透析患者高血压的控制。     

地尔硫注射液治疗老年心力衰竭伴快速房性心律失常的疗效和安全性研究

目的观察老年中度和重度心力衰竭伴快速房性心律失常(包括心房颤动和心房扑动)患者静脉注射地尔硫控制心室率的有效性和安全性。方法选取NYHAⅢ、Ⅳ级的中、重度心力衰竭伴快速房性心律失常的老年患者,给予地尔硫静脉注射,观察有效率及血压、症状和体征变化。结果85例患者入选,80例(94.1%)患者有效,心室率由用药前的(149.5±18.2)次/分下降至用药结束时的(95.3±17.5)次/分,下降幅度36.2%,平均起效时间(6.3±3.9)分钟,用药前后心室率下降有显著意义(P<0.001)。所有患者血压均有下降但多在正常范围,有5例出现低血压,1例出现Ⅰ度房室传导阻滞伴窦性心动过缓,无1例出现心功能恶化。结论静脉注射地尔硫能迅速有效地控制中重度心力衰竭伴快速房性心律失常的老年患者的快速心室率,而且安全性高。     

Pancreatic Panniculitis Associated with Allograft Pancreatitis and Rejection in a Simultaneous Pancreas–Kidney Transplant Recipient

Pancreatic panniculitis is an uncommon condition that can occur in association with pancreatic disease. We present a case of pancreatic panniculitis in a female pancreas-kidney transplant recipient 5 months post-transplant. The patient was on standard immunosuppressive medications and had acute rejection of her renal allograft. The diagnosis of allograft pancreatitis and rejection presenting with pancreatic panniculitis was supported clinically, histopathologically and by laboratory and imaging data. This is the fourth case of pancreatic panniculitis occurring in a transplant recipient and the first in a simultaneous pancreas-kidney transplant recipient. It is also the first case associated with allograft rejection. Clinicians should be aware that pancreatic panniculitis may be a manifestation of underlying allograft pancreatic disease.     

补肾排毒合剂治疗慢性肾衰竭营养不良60例临床观察

目的:观察补肾排毒合剂治疗慢性肾衰竭营养不良的疗效.方法:90例慢性肾衰竭营养不良患者随机分为治疗组60例和对照组30例,并设健康对照组30例.治疗组和对照组在综合治疗的基础上,治疗组加用补肾排毒合剂,对照组加用爱西特和百令胶囊.比较两组肾功能、营养状态和血浆瘦素、神经肽Y的变化.结果:治疗组治疗后BUN、Scr明显降低,与治疗前及对照组相比均有统计学差异(P<0.05).治疗组营养状态好转,与治疗前及对照组相比均有统计学差异(P<0.05).两组慢性肾衰竭营养不良患者治疗前Leptin、NPY水平均高于健康组(P<0.05),治疗后治疗组Leptin、NPY较治疗前下降,有统计学意义(P<0.05),但与对照组相比无统计学差异(P＞0.05).结论:补肾排毒合剂治疗慢性肾衰竭营养不良疗效明显,可降低BUN、Scr,改善营养不良状态.
