Delivery during extracorporeal membrane oxygenation (ECMO) support of pregnant woman with severe respiratory distress syndrome caused by influenza: a case report and review of the literature

Objective: To report a case of labour induction during extracorporeal membrane oxygenation (ECMO) support in a patient with acute respiratory distress syndrome (ARDS) caused by influenza and review of the literature.

Methods: Case report and the literature search of all English articles on delivery while on ECMO in patients with ARDS caused by influenza.

Results: A 25-year-old pregnant woman was initiated with ECMO due to severe ARDS caused by influenza A (H1N1) virus. When the patient had symptoms of colporrhagia and uterine contractions, the medical team decided to start labour induction while on ECMO. There were in total five case reports identified. Maternal oxygenation was improved after delivery and ECMO was successfully discontinued.

Conclusions: Maternal oxygenation was improved after delivery, which may be beneficial to reduce the duration of ECMO. Caesarean section (CS) may be the most used mode and labour induction could be another option. The procedure should be performed by an experienced ECMO team, cooperating with the obstetrician, anaesthesiologist, and ICU doctors.     

不同强度运动对大鼠心脏降钙素基因相关肽的影响

目的:探讨不同强度运动训练对降钙素基因相关肽(CGRP)在心脏组织中表达的影响及其作用机制。方法:将60只SD大鼠随机分为对照组(C组)、小强度运动组(LE组)、中等强度运动组(ME组)和大强度运动组(HE组),每组15只。建立8周不同强度运动训练动物模型,采用免疫组织化学法和计算机图像分析技术,对大鼠心脏形态结构进行观察,并进行心脏CGRP免疫组化分析。结果:8周小强度运动后,大鼠心脏CGRP表达较对照组变化不明显;8周中等强度运动后,大鼠心脏CGRP表达较对照组显著增加(P<0.05),HE染色、HBFP染色和变色酸2R亮绿染色显示心肌组织形态结构无明显改变,仅心肌纤维有轻度缺血缺氧改变;8周大强度运动后,大鼠心脏CGRP表达较对照组显著减少(P<0.05),HE染色、HBFP染色和变色酸2R亮绿染色显示心肌形态结构发生改变并存在明显的缺血缺氧损伤。结果表明,长期中等强度运动使心脏CGRP表达增加,改善了冠状循环和心肌血液供应,对心肌细胞具有保护作用;长期大强度运动使心脏CGRP对心肌细胞的保护作用减弱,可能是导致心肌发生缺血缺氧性损伤的重要原因之一。     

微板紫外速率法漏检高值ALT标本一例

谷丙氨基转移酶（Alanine asninotrasferase，ALT）检测是采供血机构血液必检项目之一，ALT检测作为早期肝病诊断的一项非特异性指标，有助于鉴别与输血相关肝炎病毒携带者，同时可以在一定程度上弥补某些肝炎病毒标志物未被检测及“窗口期”的缺陷，有助于预防输血相关肝炎的传播。我血站实验室采用微板为载体的方法进行血清ALT检测：微板紫外速率法为初检方法；微板丙酮酸氧化酶法为复检方法。在检测过程中一例高值ALT血样，微板紫外速率法检测结果为6．6U／L，出现假阴性结果造成漏检，现报告如下：     

儿科背式输液架的研制与应用

输液架是医院不可缺少的工具之一，国内医疗单位使用的输液架多种多样，但仅适用于病房使用，而适合儿科患儿移动的背式输液架甚少。针对以上缺陷，我们自行设计了一种可调式背式移动输液架，已应用于500例儿科患儿，效果较好。现介绍如下。     

外阴汗腺癌七例临床分析

目的：总结外阴汗腺癌的临床特点及治疗方法。方法：对７例外阴汗腺癌病例进行回顾性分析。结果：外阴汗腺癌的发病年龄为４０～５８岁。７例患者的治疗为局部扩大切除或根治性外阴广泛切除，２例辅以术后放疗。７例中５例存活５年以上，其中１例曾在首次治疗后第７年、１１年２次复发并于第１７年死于肿瘤。２例存活＜５年，１例在术后２年半死于脑出血，１例因脊椎广泛转移在术后１年零９个月死亡。结论：外阴汗腺癌的预后较好，局部扩大切除或根治性外阴切除，是首选治疗方法。     

Reversal of diabetes in BB rats by transplantation of encapsulated pancreatic islets

Prolonged survival of pancreatic islet allografts implanted in diabetic BB rats was achieved by encapsulation of individual islets in a protective biocompatible alginate-polylysine-alginate membrane without immunosuppression. Intraperitoneal transplantation of the encapsulated islets reversed the diabetic state of the recipients within 3 days and maintained normoglycemia for 190 days. Normal body weight and urine volume were maintained during this period, and no cataracts were detected in the transplant recipients. In contrast, control rats receiving transplants of unencapsulated islets experienced normoglycemia for less than 2 wk. These results demonstrated that microencapsulation can protect allografted islets from both graft rejection and autoimmune destruction without immunosuppression in an animal model that mimics human insulin-dependent diabetes.     

大肠肿瘤组织中EB病毒的原位杂交检测

目的：探讨EB病毒感染与人大肠癌发生的关系。方法：用原位分子杂交法对130例人大肠癌标本中EB病毒小分子RNA片段进行检测。结果：130例标本中有6例（4.48％）癌组织呈阳性反应，其中4例为男性，4例有明显淋巴细胞浸润。结论：EB病毒感染可能与我国部分大肠腺癌的发生有关，肿瘤细胞间质中大量淋巴细胞浸润可能是EB病毒感染的重要病理学特征。     

硬膜外高渗氯化钠溶液术后镇痛的临床双盲研究

为观察高渗盐水硬膜外注射术后镇痛效果,用双盲法对60例病人进行了研究。生理盐水对照级术后镇痛优良率为3.33％,镇痛有效率为10％,均需用镇痛药;高渗盐水组术后镇痛优良率为86.67％,有效率为96.67％,很少使用镇痛药。两组差别显著(P<0.05,P<0.01)。对其他感觉和运动功能无明显影响。高渗盐水组与吗啡组比较镇痛效果相同(P>0.05),副作用少(P<0.01)。说明硬膜外高渗氯化钠溶液是一种安全有效的镇痛方法,有较高推广应用价值。
