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。

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.     

Cerebral autoregulation is preserved in multiple system atrophy: A transcranial Doppler study.

Patients with multiple system atrophy (MSA) present large changes in blood pressure (BP) due to autonomic disturbances. We analyzed how this change may influence dynamic cerebral autoregulation (DCA). Simultaneous recordings of arterial BP (Finapres) and middle cerebral artery (MCA) blood flow velocity (BFV) (transcranial Doppler) were performed in 10 patients with MSA (61 +/- 12 yr of age) and 12 healthy volunteers (61 +/- 11 yr of age): cerebral BFV response to oscillations in mean BP was studied in the supine position by cross-spectral analysis of mean BP and mean MCA BFV. The DCA was also studied during the decrease in BP the first seconds when standing up from a sitting position by the assessment of the cerebrovascular resistance index (CR; mean BP/mean MCA BFV ratio). The MCA BFV/BP cross-spectral analysis showed a phase for the mid-frequency band (0.07-0.2 Hz) significantly larger in MSA, suggesting more active autoregulation in response to larger changes in BP. Changes in CR reflecting the rate of autoregulation, when standing did not differ between the two groups. These data suggest that dynamic cerebral autoregulation is preserved in MSA.     

伊贝沙坦与雷米普利对充血性心力衰竭疗效比较

目的比较伊贝沙坦与雷米普利对充血性心力衰竭(CHF)的临床疗效及安全性。方法72例CHF患者在常规治疗基础上随机分为2组。伊贝沙坦组(36例)口服伊贝沙坦150 mg.d-1;雷米普利组(36例)口服雷米普利2.5 mg.d-1。治疗前与治疗6 mo后分别用超声心动图测量左室射血分数(LVEF)、左室短轴缩短分数(LVFS)、每搏输出量(SV)、心排量(CO)、心脏指数(CI)评估心功能。结果治疗6 mo后,2组心功能较治疗前非常明显改善(P<0.01),2组之间比较差异无统计学意义(P>0.05)。结论伊贝沙坦与雷米普利治疗CHF均有效,且疗效相当。     

血管内皮生长因子及炎性因子在油酸性犬急性呼吸窘迫综合征中的变化

目的探讨油酸性急性呼吸窘迫综合征（ARDS）beagle犬血浆及肺泡灌洗液血管内皮生长因子（VEGF）、可溶性细胞间黏附分子-1（ICAM-1）、白细胞介素-8（IL-8）、肿瘤坏死因子-α（TNF—α）水平的改变。方法12只英国纯种beagle犬，静脉注射油酸0．15mL／kg，在注射油酸前、后1h，出现ARDS的典型表现时，抽血测VEGF、sICAM-1、IL-8、TNF—α，并对此时相作肺泡灌洗液VEGF、sICAM—1、IL-8、TNF-α的测定。结果beagle犬静脉注射油酸后1h血浆TNF—α升高（P〈0．05），血浆反肺泡灌洗液IL8、sICAM-1和VEGF在1h较油酸前没有明显变化（P〉0．05），beagle犬油酸型ARDS模型建立后血浆及肺泡灌洗液VECF、sICAM-1、IL-8、TNF—α均显著高于建模前（P〈0．05）。结论VEGF、sICAM-1、IL-8、TNF～α在beagle犬油酸型ARDS发生发展过程中可能均起重要作用，其水平的高低可能与ARDS严重程度及预后有关。
