Organ preservation fluid could mitigate cold ischemia injury and maintain normal function of the grafts. At present, how to reduce a series of injury caused by cold ischemia of donor liver and improve the preservation quality of grafts are the hot and challenging spots in this field. Currently, preservation fluid in clinical practice has not achieved ideal preservation effect, especially for the protection of marginal donor organs. In the context of severe donor shortage, the key solution is still to explore the optimal preservation protocol for donor liver to prevent grafts from cold ischemia injury. In this article, the mechanism of donor liver injury during cold ischemia, the classification and evolution of donor liver preservation fluid were summarized, the development direction and challenges of donor liver preservation fluid were discussed, aiming to provide novel ideas and references for the research and development of donor liver preservation fluid.

The development of artificial intelligence and other technologies has not only brought about structural and ecological evolutions in the media environment and paved the algorithm foundation in the rising meta-universe era but also accelerated our reflection on new media phenomena and human conditions, which has brought a coming paradigm shift in cognition and practice. The key core path and breakthrough point of journalism and communication are embodied in two aspects: on the one hand, it lies in audience and user analysis, that is, from the perspective of social dynamics, to study the combination of instantaneous communication and cognitive neuroscience and technology, and conduct evidence-based research on small sample experimental data to explore the causal relationship between key elements; on the other hand, it lies in the research on the re-organization of social governance, that is, from the perspective of meta universe, cloud computing, big data and artificial intelligence, to calculate data mining and social network analysis with large samples, place behavior prediction and communication effect measurement in the group of social network so as to explore the emotional cognitive processing of instantaneous effect and embodied autonomic nerve activity in the virtual and real space, which drives the reconstruction of the research method group of communication research, promotes the dialogue and resilience of communication field, and deepens the understanding of the relationship in media technology-human-virtual and real space.

目的 探讨三维(3D)打印技术制作模型在鼻颅底外科临床解剖教学中的应用。方法 根据临 床资料选取垂体瘤疾病患者1例, 从放射科图片归档和通信系统中调取其影像资料。使用 Mimics软件将患者 鼻-鼻窦-颅底 CT 元数据重建成3D数字模型。根据兴趣层面将模型切割为可观察内部解剖结构的子模型。利 用3D打印机制作模型, 将兴 趣 层 面 的 CT 影 像 打 印、裁 剪 并 与 模 型 贴 合。最 后, 校 验 解 剖 模 型 的 准 确 度。 结果 以此方法成功制作鼻-鼻窦-颅底的3D数字模型和 3D 打印模型, 同时在模型截面上复合了 CT 影像图 片, 可准确、清晰地还原显示鼻窦和颅底的内、外部的结构。结论 3D 打印技术制作的解剖模型有助于医学生 学习和掌握耳鼻喉科鼻-鼻窦-颅底临床解剖和影像, 是传统教学方法的有益补充。 [ABSTRACT FROM AUTHOR]

Objective To explore the interfering factors of cognitive function in the elderly patients with osteoporosis through questionnaire survey. Methods In this study, we used the convenient sampling method to select the aged outpatients and inpatients in Geriatrics Department of Chengdu First People's Hospital from January 2018 to December 2019. About 444 elderly patients with osteoporosis ( age ;:;,, 60 years old ) were selected as the research objects to receive bone mineral density ( BMD) test. The questionnaire survey was conducted by medical staff who had received unified training. The survey items from basic information, laboratory examination, mini mental state scale, clinical dementia assessment scale and daily activities living scale were included. We used sas9. 4 software for data analysis, analyzed the influencing factors of cognitive function in the elderly patients with osteoporosis, and brought the statistically significant ( P< 0. 05 ) variables in the single factor analysis into the multi classification logistic regression model for stepwise regression analysis. Results The prevalence of cognitive dysfunction is relatively high in the elderly patients with osteoporosis. It was shown in the uni-variate analysis that the cognitive function in the elderly patients with osteoporosis ( P< 0. 05) may be related to gender, age, education level, marital status, memory decline, smoking, drinking, regular physical exercise, egg eating habit, light tea drinking, hormone taking, calcium supplement, different interests and hobbies, community activities, hypertension, coronary heart disease, chronic obstructive pulmonary disease, non-chronic disease, triglyceride, total cholesterol, high density lipoprotein, hip bone mineral density etc. Logistic multivariate analysis showed that age, education level, marital status, memory decline, drinking, egg eating, hormone taking, community activities, hypertension, coronary heart disease, total cholesterol, high-density lipoprotein and hip bone mineral density were independently associated with the cognitive function in the elderly patients with osteoporosis ( P
