New Zealand Emergency Medicine Network: A collaboration for acute care research in New Zealand

The specialty of emergency medicine in Australasia is coming of age. As part of this maturation there is a need for high‐quality evidence to inform practice. This article describes the development of the New Zealand Emergency Medicine Network, a collaboration of committed emergency care researchers who share the vision that New Zealand/Aotearoa will have a world‐leading, patient‐centred emergency care research network, which will improve emergency care for all, so that people coming to any ED in the country will have access to the same world‐class emergency care.     

放射性肝纤维化过程的定量研究

经＾６０Ｃｏγ线照射大鼠肝区，通过光镜、电镜和图像分析仪、宣研究了照后１年肝脏的病理改变。结果表明，３０Ｇｙ组在照射后１年内逐渐发生了放射性肝纤维化病变。在肝纤维化发生过程中，肝细胞内糖原颗凿含量进行性减少，间质中胶原纤维含量进行性增加，网状纤维于照射１－３个月呈进行性增加。     

Effect of estrogen on calcium homeostasis and pituitary hormones in the growing chick

An experiment was carried out to investigate the effect of a range of estradiol (E2) doses (0.1-6.5 micrograms/g body wt/day) on vitamin D metabolism and the plasma levels of growth hormone (GH) and prolactin (PRL) in the growing chick. Doses of 0.5-0.7 microgram/g E2, which are insufficient to raise the plasma calcium level, did induce an increase in growth rate, an increase in 25-hydroxyvitamin D 1 alpha-hydroxylase (1-hydroxylase) and 24-hydroxylase activities, and an increase in plasma GH level. These parameters leveled off or fell over the dose range 1-2 micrograms/g E2 but there was evidence of a second peak in 1-hydroxylase activity at 6 micrograms/g E2. At this high dose rate, the plasma Ca level rose to 8 mM, as it does in the laying hen; 24-hydroxylase activity, growth rate, and plasma GH and plasma PRL levels all decreased. It was concluded that the dose response to estrogen in the growing chick is not linear and, in the case of 1-hydroxylase activity, may even be biphasic.     

中医外科学的起源及形成

对中医外科学的起源和形成历史，进行了概略而系统的讨论。认为：处理外科疾病是人类最早的医事活动之一，中医外科学起源于商周时期，初步形成了春秋，战国和秦汉六朝时期，经验不断积累于隋唐时期，不断完善和发展于宋金元形时期。     

紫外线照射后哺乳动物细胞DNA的期外合成

本实验用~3H-TdR掺入,液体闪烁测量法测定细胞DNA期外合成的方法,测定了小鼠和大鼠的肠淋巴结细胞、人和大鼠外周血淋巴细胞、S-180V肿瘤细胞等经紫外线照射后的UDS,观察到UDS掺入量随辐照度增加而增加。在同一辐照剂量下,以小鼠肠淋巴结细胞的UDS值最高,其次是人外周血淋巴细胞和S-180V肿瘤细胞,而大鼠外周血淋巴细胞和肠淋巴结细胞最低。     

创伤性休克病人的早期急救护理体会

目的:讨论在院前和急诊科对创伤性休克病人施行早期急救护理,对挽救病人的生命及伤情预后有重要的意义.方法:对我科1997年2月至2001年4月27例创伤性休克病人进行早期,快速,积极的补液,输血增加有效循环量,监测生命体征等综合性抢救治疗与护理措施.结果:经早期积极急救护理,26例病人收缩压维持在60mmHg以上,意识清醒,脉搏有力,转入手术室或专科治疗,1例病人伤势严重抢救无效死亡.结论:创伤性休克病人,伤势复杂,死亡率高,伤后早期院前与急诊科的有效救护,是提高抢救成功率的关键.     

中药内外并用抗尖锐湿疣复发的临床研究

目的：观察中药消疣丸/消疣擦剂内服外用防止尖锐湿疣复发的作用.方法：应用免疫学方法，检测患者治疗前后外周血T淋巴细胞亚群CD3、CD4、CD8的百分率和CD4/CD8的比值.结果：局部消除疣体后中药消疣丸/消疣擦剂内服外用对防止尖锐湿疣复发有显著疗效，痊愈率为99.66%，复发率为3.33%，与对照组相比有显著差异（P〈0.05）.结论：中药内服外用抗尖锐湿疣复发效果好。     

BS15PFACILITATING NATIONAL CONSISTENCY IN BREAST CANCER DATA COLLECTION

In Australia there is currently no consistent approach to collecting breast cancer specific data. The National Health Data Dictionary (NHDD) recommends a core set of generic data items for clinical cancer registration. However this list does not include the more detailed items required by specific tumour streams. The NBCC has developed a supplementary set of Breast Specific Data Items and definitions to serve as a guide for specialist breast cancer data collection in Australia. A multidisciplinary Working Group comprising clinical and consumer representation, including three breast surgeons, identified 16 breast specific data items for collection. The items are designed to align with items collected through the RACS National Breast Cancer Audit and leading cancer centres. A range of items from patient data (menopausal status), diagnostic data (HER2 status, sentinel lymph node), treatment (surgical margin clearance and involvement), and breast reconstruction are included. The data items are recommended as best practice for breast cancer specific data collection and aim to facilitate national consistency in defining, recording, and monitoring information about patients with breast cancer. This national approach will contribute to improved patient outcomes by informing planning, quality improvement and evaluation strategies for cancer services. The items are currently being piloted in two sites in NSW and will be available nationally in late 2007.
