刍议基层医院急诊工作对护理管理的要求

急诊室是基层医院工作的窗口，护理管理在急救工作中起着至关重要的作用。因此，基层医院对急诊护理管理提出了完善管理制度，各种物品、药品、器材做到“四定三及时”；急诊科设置集中，标志醒目；根据工作特点，严格要求护士；合理安排班次，保证充足的人力资源；加强护士急救技术和心理素质的培训，提高护理质量；不断提高护理管理者的自身素质等要求。     

Elevated concentrations of CRF in the locus coeruleus of depressed subjects.

Research evidence that corticotropin-releasing factor (CRF) plays a role in the pathophysiology of major depressive disorder (MDD) has accumulated over the past 20 years. The elevation of lumbar cerebrospinal fluid (CSF) concentrations of CRF decreased responsiveness of pituitary CRF receptors to challenge with synthetic CRF, and increased levels of serum cortisol in MDD subjects support the hypothesis that CRF is chronically hypersecreted in at least the endocrine circuits of the hypothalamic-pituitary-adrenal (HPA) axis and may also involve other CRF brain circuits mediating emotional responses and/or arousal. One such circuit includes the excitatory CRF input to the locus coeruleus (LC), the major source of norepinephrine in the brain. Furthermore, there are now reports of decreased levels of CRF in lumbar CSF from MDD patients after symptom relief from chronic treatment with antidepressant drugs or electroconvulsive therapy. Whether this normalization reflects therapeutic effects on both endocrine- and limbic-associated CRF circuits has not yet been effectively addressed. In this brief report, we describe increased concentrations of CRF-like immunoreactivity in micropunches of post-mortem LC from subjects with MDD symptoms as established by retrospective psychiatric diagnosis compared to nondepressed subjects matched for age and sex.

东莨菪碱对大鼠下丘脑室旁核精氨酸升压素的影响

目的 观察东莨菪碱对大鼠下丘脑室核精氨酸升压素的影响。方法 以不同浓度Ｓｃｏｐ推挽灌流大鼠下丘脑室旁核 结果 扣留出液中精氨酸升压素含量随推挽时间延长而增多。结论Ｓｃｏｐ可促进ＰＶＮ释放内源性ＡＶＰ，这对了解Ｓｃｏｐ抗休克的机理有重大的意义。     

钩体基因疫苗对豚鼠延髓原癌基因表达的影响

我们的研究已表明，赖型０１７株钩体外膜疏水蛋白ＯｍｐＬ３９是稳定的免疫原，在此我们分别用ＯｍｐＬ３９与钩体死菌苗和生理盐水对照免疫豚鼠，研究ＯｍｐＬ３９的免疫保护作用和免疫机理，对ＯｍｐＬ３９的抗原特异性刺激引起中枢原癌基因（Ｃｆｏｓ基因）表达进行了观察。结果表明，ＯｍｐＬ３９在豚鼠体内能产生高效价的阳性抗体，免疫保护率为１００％。在ＯｍｐＬ３９对中枢Ｃｆｏｓ基因表达的影响中，我们观察到ＯｍｐＬ３９免疫的豚鼠较空白和死菌苗组Ｃｆｏｓ表达明显少于死菌苗组和空白对照组（ｐ＜００５）。提示ＯｍｐＬ３９能特异性地抑制Ｃｆｏｓ基因的表达，减轻强毒钩体对动物体内的病理损伤，有较死菌苗强的免疫保护作用。     

前不均倾位51例临床分析

目的:探讨前不均倾位的诊断及处理方法,以期提高临床医师对前不均倾位的认识。方法:对我院1995年1月~2006年11月收治的51例前不均倾产妇的发病年龄、胎产次、发病原因、临床表现、母儿产时产后并发症及诊治方法进行分析。结果:50例前不均倾均以剖宫产结束分娩、母婴安全。1例自然分娩。结论:前不均倾位产时并发症多,不易做出早期诊断,对母婴危害大,难以经过阴道分娩,诊断一旦明确,应及时行剖宫产终止妊娠。     

肾移植前后男性性生活状况比较

目的 :探讨肾移植前后男性性生活质量的变化。　方法 :将 86例男性肾移植病人分为低年龄组 (2 5～ 35岁 ,35例 )、中年龄组 (36～ 45岁 ,2 9例 )、高年龄组 (46～ 5 5岁 ,2 2例 ) 3组 ,分别调查病人患病前后、肾移植术后性生活能力、频率、性生活满意程度等性生活状况。　结果 :86例病人患病前均有性生活能力 ,患病后有性生活能力的 :低年龄组、中年龄组、高年龄组分别为 2 8.6 %,13.8和 9.1%。肾移植术后有性生活能力的 :低年龄组、中年龄组、高年龄组分别为 88.6 %、75 .9%和 6 3.6 %。　结论 :肾移植术后的性生活质量明显好于患病后 ,年龄越轻、恢复的越理想。     

成本核算在医院管理中的应用和进展

目前,我国医疗总费用的增长速度大大超过了国民经济和财政收入的增长速度[1]。卫生经费投入不足,药费居高不下,政府、企业不堪重负,医疗制度改革势在必行。成本核算是医院经济管理的基础工作,核算工作的深度和层次直接影响医院成本管理的成效。1医疗成本核算的概念医疗成本是卫生服务过程中所发生的物化劳动和活劳动耗费的总和。它由以下6大类成本构成:劳务费、业务费、公务费、原材料费、固定资产折旧费和管理费。医疗成本核算是按照《医院财务制度》有关成本费用开支范围的规定,核算医院在医疗服务过程中所支出的物质消耗、劳务报酬以及有…     

Interactions between membrane IgM and the cytoskeleton involve the cytoplasmic domain of the immunoglobulin receptor

Cross-linking induced interactions between the membrane form of immunoglobulin (mIg) and the cytoskeletal matrix have been described by several groups. To date, the function of mIgM association with the cytoskeleton is not yet understood. Delineation of the molecular basis of these interactions will be instrumental in elucidating their function. We have previously shown that the Igα/β heterodimer is not required for ligand-induced mIgM binding to the cytoskeleton. In this study, we have investigated the role of other B cell-specific proteins in mediating these interactions. For this, we expressed mIgM in the non-hematopoietic human cervical carcinoma cell line HeLa S3 and verified the capacity of the surface-expressed IgM to interact with the cytoskeletal matrix upon cross-linking with anti-μ chain antibodies. We show here that only the mIgM molecule itself and no other B cell-specific protein(s) is required in mediating mIgM interactions with actin filaments. In an attempt to determine the cytoskeleton-binding site of mIgM we investigated the role of the cytoplasmic tail of mIgM (KVK) in binding the receptor to actin-based microfilaments. Using mutated forms of mIgM expressed in J558L cells, we show here that KVK plays a role in mediating these interactions. The absence of KVK did not, however, completely abrogate mIgM-cytoskeletal interactions, suggesting that there are additional molecular requirements for the ligand-induced mIgM binding to the cytoskeletal matrix.
