Concerns for medical radiation programs in Australian universities

The Australian higher education system is in a state of great change. The Federal education minister, Dr Brendan Nelson, has indicated that he intends to continue introducing far-reaching reforms that will impact significantly on how universities conduct teaching and research. The future allocation of government funding for university programs, including those in medical radiation, will have a significant effect on how those programs are delivered and could even determine whether programs remain viable. There will be a financial imperative for academic departments to strengthen research activity and to obtain funding from non-government sources, such as full-fee paying students, in order to generate enough income to cover program delivery. Medical radiation education in Australia is also facing many other challenges. Some of these are longstanding, such as the high cost of medical radiation program delivery, poor levels of research activity and difficulty in recruiting and retaining academic staff. Other problems have arisen recently, such as increased competition for students and a critical shortage of available training placements in clinical practice. The aim of this paper is to raise and explore these issues from a university perspective.

Making clinical decisions for dental care: concepts to consider

Clinical decisions are often made with incomplete information, yet patient care decisions are made every day. Patients vary clinically, uncertainty exists in diagnostic and prognostic information, and many preventive and treatment alternatives have not been formally assessed for their effectiveness. Because scientific information will never answer all clinical questions, clinical decisions are partially based on probabilistic information.
This paper describes how to apply clinical decision making to diagnosing and managing dental caries and periodontal diseases. By using explicit information to quantify probabilities and outcomes, clinical decision making analyzes decisions made under uncertain conditions and the uncertain impact of clinical information.
Clinical decision making incorporates concepts for preventing, diagnosing and treating dental caries and periodontal diseases: risk assessment, evidence-based dentistry, and multiple oral health outcomes. This information can serve as a tool for clinicians to augment clinical judgment and expertise.     

采用半透明效果实现医学三维整体可视化

目的通过改进直接体绘制技术（DVR）算法中的关键步骤，绘制能表达数据场中不同层次组织的内部结构。方法根据界面对光线的反射和物质本身对光线的衰减，将数据场划分为边界不丰富的简单数据场和边界丰富的复杂数据场，从而采用分段线性函数来构造阻光度传递函数（TF）；将数据场中低灰度体素点看为一种不发光但会导致采样光线衰减的物质；根据采样结束时采样光线的阻光度分布来调整TF，完成三维绘制。结果绘制出了不同层次组织的内部结构。结论本算法有效地解决了体素点相互遮挡的问题，实现了医学三维整体可视化。     

中西医结合治疗Leriche综合征78例

目的:总结中西医结合治疗Leriche综合征的方案.方法:回顾性总结Leriche综合征的临床治疗78例,均行人工血管主股或主髂动脉转流手术,术后静脉应用低分子右旋糖酐、复方丹参注射液和维脑路通.结果:手术结束后均能触及股动脉和动脉搏动,手术后7 d,患肢缺血症状均得到改善.手术后3月,患肢缺血症状消失,64例阳痿现象得到改善.彩色超声血管吻合口及人工血管内均未见血栓.结论:人工血管主股动脉转流或主髂动脉转流是治疗Leriche综合征较好的手术方案,围手术期合理应用扩血管、祛聚、活血化瘀药物,同时及时处理伴发疾病是提高临床治愈率和提高远期疗效的关键.

中药膳食配合运动干预对肥胖性脂肪肝的影响

目的 探讨中药膳食配合运动干预对肥胖性脂肪肝的影响。方法 将68例脂肪肝患者随机分为对照组和观察组各34例。对照组常规给予低脂饮食和易善复、大黄庶虫丸等降酶保肝治疗；观察组按常规方法治疗外，采用中医辨证施食予以活血化淤、健脾利湿的中药膳食疗法配合运动干预．疗程均为1年。结果 治疗后观察组体重、甘油三酯、总胆固醇、谷丙转氨酶等显著低于对照组（均P〈0．01）。结论 中药膳食配合运动干预对肥胖性脂肪肝疗效显著。     

扶正固本法对青少年哮喘患者基因表达的影响

目的 研究复方中药敏康片治疗青少年哮喘的疗效和作用机理。方法 选择20例青少年哮喘患者进行治疗，另设青少年特应性皮炎患者组（20例）和青少年正常组（19例）为对照。哮喘组和皮炎组口服敏康片，疗程为6个月，观察疗效、血清总IgE及FcεRIβ、IL-4Rα基因表达改变情况。结果 哮喘组显效6例，有效12例，无效2例，总有效率90％；皮炎组显效4例，有效13例，无效3例，总有效率85％；哮喘组IgE治疗前后有显著差异（P〈0．01）。皮炎组IgE治疗前后有差异（P〈0．05）；用Northern blot法检测FctRlt3、IL-4Rα基因，IL-4Rα吸光度值两组治疗前均较正常组高，哮喘组治疗后降低。FcεRIβ吸光度值两组治疗前均较正常组高，治疗后均降低。结论 复方中药可以调整青少年哮喘患者相关基因表达，改善患者过敏状态，缓解临床症状。     

血栓的形成及中药抗栓溶栓概况

血栓形成是由于正常的凝血机制的扰乱而促使某些血细胞和蛋白质被激活相互作用而最终导致血小板－纤维蛋白血栓的形成．ＡＴ－Ⅲ、ＰＣ、ＴＭ是体内重要的抗凝物质．白细胞与血小板的相互作用、ＰＧＩ２／ＴＸＡ２值以及许多疾病状态是影响血栓形成的诸因素．许多中药具有抗血小板聚集、抗血栓形成的作用，包括生物碱类，如小檗碱、北豆根碱和钩藤碱；中药蒲黄、花椒、沙棘、大蒜的提取物；一些中药复方等．
