特需病房护理工作特点及管理对策

特需医疗服务是顺应社会政治、经济、文化和组织形态的发展,伴随医学模式的改变,在医学高度进步的知识经济时代,充分利用医学及相关学科的资源而产生的一种特殊医疗服务形式[1]。特需医疗的特点不是医疗原则和医疗质量的特殊,而是通过改善医疗服务时间、空间、生活设旋、就诊环     

代孕技术中的伦理道德及法律问题

新近发展的代孕技术给众多不孕夫妇带来为人父母的喜悦之时,也对人们传统的生殖伦理观念形成冲击并挑战现存法律制度.人们不仅要肯定代孕技术的合理性,也要警惕其所产生的潜在的破坏性影响.合理利用该技术和制定相应的法规是避免出现伦理和社会混乱的有效途径.

1临床资料 患者女，45岁。因左下肢胀痛1周入院。体格检查：自主体位。心肺腹未见异常，左下肢较对侧明显肿胀增粗，浅静脉明显扩张，皮温增高，Homans征阳性。化验检查：D-二聚体5mg／L。左下肢静脉彩超示：左髂总静脉、髂外静脉、股静脉、胭静脉血栓形成。次日在介入中心经右股静脉行下腔静脉滤器置入术，后在彩超引导下经左胭静脉置入5F鞘管，经鞘管送入5F溶栓导管1根，送入50cm阻力明显。彩超示：左髂外静脉可见导管影，左髂总静脉显示不清。     

白细胞介素-8在哺乳动物生殖过程中的作用

白细胞介素-8(IL-8)作为中性粒细胞趋化因子和促血管生成因子,受到人们的重视。研究表明,IL-8促进卵细胞的发育、成熟,诱发排卵;在输卵管和子宫内膜的表达随月经周期而变化;参与胚泡着床和胚胎发育。本文综述IL-8在哺乳动物生殖过程中的重要作用。

Measurement of alveolar derecruitment in patients with acute lung injury: computerized tomography versus pressure–volume curve

Introduction  

Positive end-expiratory pressure (PEEP)-induced lung derecruitment can be assessed by a pressure–volume (P–V) curve method or by lung computed tomography (CT). However, only the first method can be used at the bedside. The aim of the study was to compare both methods for assessing alveolar derecruitment after the removal of PEEP in patients with acute lung injury or acute respiratory distress syndrome.

KGF在乳腺癌的表达与临床意义

目的:探讨KGF蛋白在人乳腺癌的表达与意义,与临床病理因素及生物学指标的相关性。方法: 采用免疫组化方法检测KGF在63例乳腺癌组织中的表达,并与正常乳腺组织对照。结果:63例乳腺癌组织中34例肿瘤细胞表达KGF(54．0％),正常乳腺上皮细胞未表达(P<0．01),在乳腺癌间质细胞和正常乳腺组织间质细胞表达率分别为34．9％和16．7％(P>0.05)。其在肿瘤细胞中的表达与低分化相关,与ER、PR呈负相关,与Ki-67呈正相关,与Ki-67的协同表达与淋巴结转移正相关。结论: KGF在乳腺癌肿瘤细胞的表达可能促进乳腺癌的发生发展,并且与低分化、预后不良有关。     

Effect of the menstrual cycle and oral contraceptives on aromatase and cyclooxygenase-2 expression in adenomyosis.

OBJECTIVES: To determine whether aromatase expression in the eutopic endometrium and adenomyotic foci is affected by previous use of oral contraceptives containing gestodene, and to determine whether changes in cyclooxygenase-2 (COX-2) expression occur in adenomyosis during the menstrual cycle. PATIENT AND METHODS: This was a retrospective cohort study carried out in paraffin-embedded endometrial tissue obtained from patients with a histological diagnosis of adenomyosis obtained during the proliferative (n = 25) and luteal (n = 10) phases of the menstrual cycle and following the use of continuous oral contraception with gestodene/ethinyl estradiol (n = 7). COX-2 and aromatase expression were measured in both eutopic endometrium and adenomyotic foci using immunohistochemical methods. RESULTS: Aromatase expression was detected in 80% of the endometrial slices by immunohistochemistry. In positive cases, aromatase was mainly detected in the stromal cells of the eutopic endometrium, whereas in the adenomyotic foci this expression was negative in the majority of the cases. Oral contraceptives containing gestodene, on the other hand, were effective in suppressing aromatase expression in both eutopic and ectopic endometrium. COX-2 expression was detected by immunohistochemistry in the glandular epithelium of both eutopic endometrium and adenomyotic foci and there were no significant changes in its intensity throughout the menstrual cycle. CONCLUSION: Aromatase expression in the eutopic endometrium and adenomyotic foci is suppressed by oral contraceptives containing gestodene. Increased aromatase activity may be responsible for the persistent COX-2 expression during the luteal phase.     

太阳病"汗法"初探

仲景所著《伤寒论》冠古绝今,书中398条原文,太阳病篇所占178条,足以突出太阳病篇在六经辨证中的重要性.众所周知,太阳病的基本病机是感受风寒,营卫失调;其基本治则为辛温解表;“汗法”在治疗中占有极其重要的地位.用之正确则药到病除,用之不当则变证从生.仲景在太阳病篇中对“汗法”有很详细的描述,初探如下.
