试论医院药师的业务标准

作者依据医药卫生事业发展对药学人员的要求，在调查了80家综合医院药师工作现状的基础上，提出了药师在调剂、制剂、药品检验、药学科研、药品储存供应、药学综合知识与技能6个方面应具备的业务标准，为我国实行医院药师资格准入控制提供参考。     

小儿糖尿病血胰岛细胞抗体与胰岛素自身抗体

报道并分析20例小儿糖尿病患儿的临床资料及血胰岛细胞抗体(ICA)及胰岛素自身抗体(IAA)的测定资料。在20例患儿中,临床表现多不典型。在酮症酸中毒的治疗中小剂量胰岛素疗法方法简便,安全可靠,并发症少。本组患儿ICA阳性率55%,IAA阳性率30%,经卡方检验均显著高于对照组,推测病毒感染引起自身免疫反应,产生ICA及IAA而致本病发生。

Postprandial induction of chaperone gene expression is rapid in mice.

Molecular chaperones assist in the biosynthesis and processing of proteins. Most chaperones are induced by physiological stresses. We have shown that dietary energy restriction decreases the mRNA and protein levels of many endoplasmic reticulum chaperones in the livers of mice. Here, we have investigated the response of chaperone mRNA to feeding. Control and 50% energy-restricted C3B10RF1 mice were deprived of food for 24 h, fed, and killed 0, 1.5, 5 or 12 h after feeding. Chaperone mRNAs were strongly induced as early as 1.5 h after feeding in control and energy-restricted mice. The integrated levels of these mRNA over 24 h were significantly lower in energy-restricted mice. The mRNA response to energy intake was mirrored over the course of days in the level of chaperone protein. A similar but smaller response to feeding was found in kidney and muscle. Puromycin and cycloheximide failed to inhibit the feeding response, suggesting that feeding releases chaperone expression from an unstable inhibitor. Studies with dibutyryl-cAMP- and glucagon-supplemented, normal and streptozotocin-diabetic mice suggest that glucagon and insulin may be mediators of the feeding response. Adrenalectomy enhanced the feeding induction, but dexamethasone administration had no effect. Thus, postprandial changes in insulin and glucagon may link chaperone gene expression to feeding, possibly in several tissues including liver.     

人肿瘤特异抗原MAGE-3基因疫苗的构建和表达

目的：克隆肿瘤特异性共享抗原mage-3基因，制备基于α－病毒复制酶的高效黑色素瘤特异性基因疫苗。方法：用RT-PCR方法从黑色素瘤细胞系LB373中制备mage-3基因，以含α－病毒复制酶的哺乳细胞高效表达质粒pSMART2a为载体，构建重组DNA疫苗。重组子用载体中的T7和T3启动子序列为测序引物进行自动测序。再将鉴定过的重组质粒用脂质体法转化293细胞，用免疫印迹法和免疫组化法鉴定转化细胞中mage-3蛋白的表达。结果：正确构建了mage-3/pSMART2a重组质粒，并且在转化此质粒的293细胞中检测出了mage-3蛋白的表达。结论：此重组mage-3/pSMART2a质粒可以作为肿瘤特异的DNA疫苗，可进行下一步的肿瘤动物模型的疫苗接种及相关免疫学效应研究。     

护理工作量测量的影响因素

对影响护理工作量测量的护士因素、患者因素及环境等诸多因素进行综述。提出管理工作者需根据目前护理人力资源现状和配置标准进行分析、论证，明确界定护理工作的性质和内容，制定适合我国国情的护理工作量测量工具，以合理分配护理人力资源，使有限的护理资源满足广大患者的需要，从而提高社会效益和经济效益。
