Becoming a mother — an analysis of women's experience of early motherhood

This paper presents the results of a qualitative study conducted by midwife researchers into women's experience of new motherhood. Data were collected using focus groups involving 55 first-time mothers and analysed using grounded theory method. The analysis produced six categories: 'realizing', 'unready', 'drained', 'aloneness', 'loss' and 'working it out'. The core category, 'becoming a mother', integrates all other categories and encapsulates the process of change experienced by women. Also explained are factors mediating the often distressing experience of becoming a mother. The analysis provides a conceptualization of early motherhood enabling the development of strategies for midwives, nurses and others helping women negotiate this challenge.     

Antenatal education – where next?

The history of antenatal education throws light on why contemporary class attenders represent only a particular section of the childbearing population. Since Victorian times, the non-availability of the women's network to middle class women has forced them to seek knowledge of their own bodies, confidence in their childbearing capacities and the support of other women through formal educational opportunities. Research suggests that antenatal classes often fail to provide women with a realistic account of birth and parenting to replace the lived experience of earlier decades and may not be facilitated in such a way as to create the support groups which class attenders critically need. Teaching approaches often promote dependency amongst clients rather than nurturing the decision-making skills required by a consumer-driven maternity service.     

中药蝶脉灵注射液在心肺复苏中脑保护作用的实验研究

目的 探讨中药蝶脉灵注射在心脏骤停时对脑复苏的作用。方法 用电刺激导致室颤制备家兔心脏骤停模型，在光镜和电镜下观察大剂量肾上腺素治疗时，蝶脉灵注射液对脑组织的影响。结果 蝶脉灵注射液对脑细胞有明显的保护作用。结论 蝶脉灵注射液能明显改善心脏骤停时脑缺血性损害，因而有利于脑复苏。     

踝部开放性骨折的急症手术治疗

目的探讨踝部开放性骨折的损伤特点及相关的急症手术技术特点。方法2001年8月至2006年4月，急症手术治疗踝部开放性骨折51例，男39例，女12例；年龄18-72岁，平均36岁。伤口Gustilo分度，Ⅰ度3例，Ⅱ度37例，ⅢA度7例，ⅢB度3例，ⅢC度1例。急诊给予有效抗生素治疗，尽早开始手术。冲洗及彻底清创后，根据骨折类型、粉碎程度及伤口情况制定骨折处理的顺序，依次完成骨折复位、固定。结果48例患者获得随访，随访时间8-48个月，平均26个月。无一例发生深部感染。12例伤口发生浅表皮缘坏死，2例伤口延迟愈合，2例伤口发生浅表感染。踝部骨折在10-18周（平均13周）愈合。采用AOFAS踝后足功能评分标准，48例评分在76-100分，平均90分。结论踝部开放性骨折在急症手术时应彻底清创，注意保护皮肤活力。在处理后踝骨折时，可采用胫骨远端脱出法。多数手术应先精确复位、固定外踝骨折，对旋后内收型、外踝严重粉碎的踝部骨折应先进行内踝骨折的复位、固定。对严重的下胫腓联合分离，应直视下复位且常规使用下胫腓螺钉固定。     

National Alliance for Oral Health Consensus Conference on Medically Necessary Oral Health Care: Legal issues

This paper examines medical malpractice law as it applies to medically necessary oral health care. The basic legal concepts and reported cases involving medically necessary oral health care are reviewed. It is concluded that dental professionals and consumer advocates must advance their educational and legislative advocacy efforts so that health professional colleagues and the public will become aware of the importance of these services and insurers will routinely include coverage of medically necessary oral health care in their medical and dental policies. While failure to provide medically necessary oral health care can be violative of patient rights and legally actionable, medical malpractice litigation should always be the behavior modifier of last resort.     

中药灵芝对健康人甲襞微循环的作用

系统观察５７例健康人口服灵芝（灵芝多糖体５５ｍｇ／片）前后甲襞微循环的变化。结果显示：服药前后大、小动脉血压无显著变化；口服灵芝３天后输入枝口径及输出枝口径均有明显扩张；管袢密度、红细胞流速增加不显著。口服灵芝７天的动态变化显示，服药８ｈ后输入枝、输出枝口径即有显著扩张，第７天管袢密度开始明显增加。服用不同剂量灵芝（２片、４片、８片，３次／日）３ｈ后，管袢密度、输入枝、输出枝口径、流速均有增加趋向，但Ｐ＞０．０５，其中８片组管袢口径、管袢密度有显著增加（Ｐ＜０．０５），但红细胞流速却有显著下降（Ｐ＜０．０５）。结果提示：连续、适量（２片，３次～４次／日）服用灵芝，可显著改善微循环灌流量，从而改善和保护组织及脏器功能。     

Evaluation of endothelial cell migration with a novel in vitro assay system

In this study we introduce a novel in vitro 'oil-drop' assay system for the measurement of endothelial cell (EC) migration, based on the original concept of the Teflon fence assay (Pratt et al., 1984; Am. J. Pathol. 117: 349–354). An aliquot of 15–20,000 human umbilical vein EC (HUVEC) is pipetted through a layer of mineral oil. The cells readily attach, spread and migrate on the surface of a matrix-coated tissue culture dish as a confluent circular monolayer. Migration is measured as the net increase in the total area covered at 24 hours. We have used this system to quantify EC migration on matrices composed of a mixture of type I collagen and either von Willebrand factor (vWF) or fibronectin (FN) in the presence or absence of tumor necrosis factor (TNF). Plating efficiency on both vWF/collagen and FN/collagen, measured by counting cells after attachment and spreading, is about 80%. With this method, migration on vWF/collagen was about 6.4 mm² and 5.3 mm² for TNF-treated and untreated HUVEC, respectively. HUVEC migration on FN/collagen was slightly greater – 6.4 mm² and 6.5 mm² with and without TNF treatment, respectively. During the 24 hour time period, HUVEC numbers increased 30–40% on vWF/collagen, and 60–80% on FN/collagen, with increased proliferation observed with TNF- treatment. EC proliferation could be completely inhibited by 2 mM hydroxyurea. This assay system has proven useful in our studies to quantify cell migration and proliferation.
