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 研究自体动静脉内瘘全程规范化护理的可实施性及优势。 方法 制定自体动静脉内瘘全程规范化护理工作流程及标准，将2011年6月－8月经自体动静脉内瘘行维持性血液透析患者随机分为观察组（125例）和对照组（115例），分别予以全程规范化护理和普通护理，对比分析两组之间内瘘不良事件发生率、患者满意度、护士认同度等指标的差异。 结果 两组内瘘不良事件发生率分别为8.0%和21.0%，患者满意度分别为98.4%和84.3%，差异均有统计学意义（P＜0.05）；两组护士对本组护理模式认同度均为90.0%，差异无统计学意义（P＞0.05）。 结论 自体动静脉内瘘全程规范化护理模式能有效降低内瘘不良事件发生率并显著提高患者满意度，值得临床推广。
