发挥远程教育优势推进医学继续教育发展

《教育部关于加强高校网络教育学院管理提高教学质量的若干意见》中强调指出：高校网络教育学院要以在职人员的继续教育为主，要充分发挥网络教育的优势，为在职人员更新知识、增强技能、不断学习、不断提高提供良好的服务。然而，要使医学院校在开展继续教育中发挥更大的作用，推进医学继续教育的发展，远程教育不仅是解决这一问题的有效途径，而且将成为开展医学继续教育的强大动力。     

Molecular genetics and transfusion management in a child with Bernard Soulier syndrome.

We present a case of Bernard Soulier syndrome in a 9-year-old boy caused by a novel genetic mutation. This child was shown to be homozygous for a single nucleotide deletion (c.1077delG) in the GP1BA gene not previously reported. Clinically, the boy has become refractory to platelet transfusions with both allo-antibodies and iso-antibodies and a massive transfusion requirement for ongoing haemorrhage. We describe the critical role that the blood product transfusion continues to play in the management of Bernard Soulier syndrome and discuss therapeutic options in these patients.     

Future direction of nanomedicine in gastrointestinal cancer]

Cancer is one of the leading causes of death in human, and among various cancers, gastrointestinal cancers occupy more than 55%. Gastric cancer is the first leading cause of cancer-related mortality in the world and the number of pancreas and colon cancers are increasing remarkably during last two decades which will continue to increase in the future. Even though the clinical importance of gastrointestinal cancers is very high and endless efforts has been made to develop novel diagnostic and therapeutic methods to improve the patient's quality of life and survival, the realistic advance in the actual survival benefit of the cancer patients are still strongly required. Nanotechnology has the power to radically change the way of cancer diagnosis and treatment. Currently, there is a lot of researches on novel nanodevices capable of detecting cancer at its earliest stage, pinpointing its location within the body, and delivering anticancer drugs specifically to the malignant cells. Nanoscale devices can readily interact with biomolecules both on the cell surface and within the cell. In addition, nanoscale devices are already proven that they can deliver therapeutic agents to target cells even within specific organelles. Major areas in which nanomedicine is being developed in cancer include early detection and proteomics, imaging diagnostics and multifunctional therapeutics. Because nanotechnology would provide a technical power and tool that enable new diagnostics, therapeutics, and preventives to keep pace with today's explosion in knowledge in the future, it would be very useful to know the perspectives in the direction of nanotechnology as a major clinician responsible for the patients with gastrointestinal malignancies.

In vivo actions of insulin-like growth factor-I (IGF-I) on bone formation and resorption in rats

The in vivo action of insulin-like growth factor-I on bone metabolism has been studied using a new model. Insulin-like growth factor-I (IGF-I) was continuously infused into the arterial supply of the right hindlimb of ambulatory rats for up to 14 days and the effects on cortical and trabecular bone formation and the number of osteoclasts were determined by histomorphometric techniques. The contralateral limb acted as an internal control. IGF-I infusion significantly increased cortical bone formation (p less than 0.01). Trabecular bone was increased 22% (p = 0.07), but the infusion was only for seven days. These effects of IGF-I were age dependent, being absent in young, rapidly growing animals, but present at least until one year of age. IGF-I appears to be a purely anabolic hormone for bone formation, since it significantly stimulates osteoblasts and decreases the number of osteoclasts. Thus, although IGF-I mediates the growth-promoting effect of growth hormone, it does not mediate growth hormone's action on bone resorption.

Anterior translocaton of pulmonary artery without aortic transection in repair of tetralogy of Fallot with absent pulmonary valve.

We developed a technique of translocation of the pulmonary artery anterior to the ascending aorta without transection of the aorta in the repair of tetralogy of Fallot with absent pulmonary valve. Our technique includes detachment of the main pulmonary artery (MPA) from the pulmonary annulus, vertical division of the MPA, anterior translocation of the pulmonary artery with patch augmentation between the vertically divided MPA.     

三种泻心汤及其类方不同配伍对正常大鼠胃粘液成分的影响

目的:探讨半夏泻心汤及其类方不同配伍对正常大鼠粘液含量的影响.方法:用均匀设计法对半夏泻心汤及其类方进行组方药量变化,以胃粘液含量为药理学指标,对所得的药理实验数据进行逐步回归分析.结果:与胃粘液含量关联度最大的为黄连,可以显著降低其含量,其次对半夏、大枣和甘草的交互项,可增加胃粘液含量.药物之间存在复杂的交互作用.结论:均匀设计为研究类方配伍提供了一种可供参考的试验设计方法.
