Late postpartum eclampsia. Apropos of a case

We report the case of a 32-year-old multipara who presented preeclampsia on the fourth day after childbirth without receiving proper treatment that progressed to eclampsia 4 days later. Pregnancy and delivery had been uneventful. The patient presented proteinuria (30 mg/dl), serum total proteins 5.3 g/dl and serum albumin 3.3 g/dl. Blood pressure was controlled with methyldopa, 500 mg at six-hour intervals by intravenous route. The patient presented hypoxemia secondary to bilateral pleural effusion and aspirative pneumonia requiring mechanical ventilation and invasive hemodynamic monitoring. Treatment with cefotaxime, 1 g at six-hour intervals by intravenous route and clindamycin, 600 mg at six-hour intervals by intravenous route was initiated. Sedation was maintained with thiopental sodium, 3 mg/kg/hour in continuous infusion. At dismission, the patient was completely recovered from her clinical picture and needed no antihypertensive therapy. Physiopathologic features and the aforementioned complications are discussed with particular reference to differential diagnosis.     

MRI同层动态增强对垂体微腺瘤的诊断价值

目的：分析垂体微腺瘤的MPd同层动态增强特征。方法：对40例临床怀疑为垂体微腺瘤的病人行同层动态增强MPd扫描，并绘出时间一信号强度曲线图。结果：40例病人中共检出垂体微腺瘤26例。同层动态增强后垂体微腺瘤的MPd表现为圆或椭圆形的低或稍低信号，似“充盈缺损”；垂体微腺瘤的最大信号强度多出现在注入造影剂后32～96s，以64s最明显。结论：同层MPd动态增强对垂体微腺瘤的诊断有较高价值。

Recycling and EH domain proteins at the synapse

In neurons, a network of endocytic proteins accomplishes highly regulated processes such as synaptic vesicle cycling and the timely internalization of intracellular signaling molecules. In this review, we discuss recent advances on molecular networks created through interactions between proteins bearing the Eps15 homology (EH) domain and partner proteins containing the Asn–Pro–Phe (NPF) motif, which participate in important aspects of neuronal function as the synaptic vesicle cycle, the internalization of nerve growth factor (NGF), the determination of neuronal cell fate, the development of synapses and the trafficking of postsynaptic receptors. We discuss novel functional findings on the role of intersectin and synaptojanin and then we focus on the features of an emerging family of EH domain proteins termed EHDs (EH domain proteins), which are important for endocytic recycling of membrane proteins.     

祖国传统医学对骨质疏松症的治疗进展

骨质疏松症是以骨量减少和骨组织的纤维结构退化为特征的代谢性骨病。随着21世纪我国老龄化社会的到来，骨质疏松发病率明显增高，已逐渐成为世界性广泛关注的问题。原发性骨质疏松分为I、Ⅱ两种类型。I型为高代谢型，主要是绝经后骨质疏松，由雌激素缺乏，而使骨代谢呈负平衡，骨吸收相对增强引起；Ⅱ型是低骨转换型，主要为老年性骨     

6种中药制剂治疗急性脑梗死的成本-效果分析

目的：运用药物经济学的方法对在我院应用的6种中药注射液进行成本-效果分析。方法：271例急性脑梗死患者依据药物治疗方案不同分为6组，即血塞通组、舒血宁组、苦碟子组、疏血通组、川芎嗪组、丹红组，分别观察疗效，并运用药物经济学的方法进行成本-效果分析。结果：疏血通组的成本为3 419.90元，总有效率最高（91.84%），6组间增量成本-效果最低。因此疏血通组是较为合理、经济的方案。     

环形电刀切除术治疗慢性宫颈炎的临床研究

目的 探讨环形电刀切除术治疗慢性宫颈炎的临床价值。方法 回顾性分析经环形电刀切除术治疗的慢性宫颈炎病人1632例，其中958例行宫颈炎性病灶消融术，511例行宫颈环切术。163例行宫颈锥切术。比较不同术式的术中出血量、手术时间、疗效以及手术并发症发生情况。结果 环形电刀切除术对各种类型慢性宫颈炎的总治愈率达95．8％，总有效率为100％，各术组间治疗效果无明显差异。手术时间及术中、术后出血量最大的为宫颈锥切组，其次是宫颈环切组，再次为病灶消融术组。术后有4．4％的患者出血量超过月经量。需再次止血。结论 环形电刀切除术是治疗慢性宫颈炎的一种安全而有效的方法，适当的操作方法可减少并发症的发生。宫颈病灶消融术效果好而并发症更少。     

抗醛糖还原酶单克隆抗体的制备与特性鉴定

目的:制备抗醛糖还原酶(AR)的单克隆抗体(mAb),并与本室制备的抗醛糖还原酶相似蛋白(ARL-1)mAb进行比较。方法:经RT-PCR获得AR基因,将基因插入pGEX-4T-1(His)6C中,构建重组质粒pGEX-4T-1(His)6C-AR,以重组质粒转化E.coliRosetta诱导表达GST-AR蛋白。以纯化的GST-AR蛋白免疫BALB/c小鼠,采用杂交瘤技术制备mAb。应用间接ELISA和Western blot方法对mAb进行筛选和鉴定。使用Clustalx和Antheprot软件,比较AR与ARL-1的同源性,表达GST-dAR[80~142氨基酸(aa)],与ARL-1差异较大;并分析AR的抗原性,表达GST-dA1(1~79aa)、GST-dA2(80~99aa)、GST-dA3(111~142aa)、GST-dA4(143~316aa)。利用AR全长及截短蛋白,采用Western blot分析制备的抗AR mAb识别AR抗原的部位。结果:获得3株稳定分泌抗AR mAb的杂交瘤细胞系ARB3、AR7B3G4和ARF10。3株抗GST-AR的mAb均为IgG1(κ型),腹水mAb效价为1∶4×105,细胞培养上清mAb效价为1∶1×104,3株mAb均可与胎盘组织中的AR蛋白起反应,而与GST-ARL-1和GST蛋白无交叉反应。它们分别为抗GST-dA1、GST-dA3和GST-dA4蛋白的mAb。结论:成功地制备了3株特异性抗AR mAb,可分别识别AR的1~79、111~142、143~316位氨基酸。将它们与抗ARL-1mAb联合应用,将有助于进一步研究AR与ARL-1蛋白的功能,并为深入探讨AR、ARL-1与相关疾病的关系及进行大规模的流行病学调查提供了有力的工具。     

Extraperitoneal endometriosis: a diagnosis to be considered

Summary BACKGROUND: Endometriosis is a relatively common pathology in women of childbearing age and of low parity but rarely shows extraperitoneal involvement. The main aim of this paper is to raise the attention of specialists to the necessity of carrying out penetrating diagnosis of nonspecific extraperitoneal masses occurring in women of reproductive age. METHODS: We performed a retrospective review of six patients diagnosed with extraperitoneal endometriosis who were treated at the Vega Baja University Hospital (Spain) during the last 5 years. RESULTS: Surgical treatment had positive results in five patients. The preoperative diagnosis was correctly made in only two patients. The accurate aetiology of endometriosis remains unknown and diagnosis is based on clinical and cytopathological findings. CONCLUSIONS: Surgical treatment of extraperitoneal endometriosis is recommended. However, postoperative follow-up is obligatory and hormonal suppressive therapy may be necessary. Medical treatment with gestagens, Danazol, or agonists of the gonadotropin-releasing hormone are ineffective in endometriomas which are bigger than 2 cm.
