Three-dimensional (3D) printing, an emerging rapid prototyping technology, has been widely used in biomedical field. 3D printing was originally used to construct the visualization models and molds in medicine. With the development of 3D printing in biomedical field, the technology was gradually applied in complex tissue regeneration and organ reconstruction. Artificial tissues and organs obtained by 3D printing are expected to be used for organ transplantation, new drug development and drug toxicity evaluation in the field of medicine and health care research. This paper describes the individualized application of 3D printing technology in liver surgery and introduces the research progress of 3D bioprinting technology in liver transplantation, drug metabolism and hepatotoxicity evaluation, and prospects its future development trend to provide a reference for further study.
目的 研究自體動靜脈內瘺全程規范化護理的可實施性及優勢。 方法 制定自體動靜脈內瘺全程規范化護理工作流程及標準，將2011年6月－8月經自體動靜脈內瘺行維持性血液透析患者隨機分為觀察組（125例）和對照組（115例），分別予以全程規范化護理和普通護理，對比分析兩組之間內瘺不良事件發生率、患者滿意度、護士認同度等指標的差異。 結果 兩組內瘺不良事件發生率分別為8.0%和21.0%，患者滿意度分別為98.4%和84.3%，差異均有統計學意義（P＜0.05）；兩組護士對本組護理模式認同度均為90.0%，差異無統計學意義（P＞0.05）。 結論 自體動靜脈內瘺全程規范化護理模式能有效降低內瘺不良事件發生率并顯著提高患者滿意度，值得臨床推廣。
