Essential training steps to achieving competency in the basic intraoperative transesophageal echocardiography

null

《医学前沿（英文）》 2015年第9卷第1期页码 123-128 doi: 10.1007/s11684-014-0366-7

摘要：

Guidelines for the intraoperative transesophageal echocardiography (TEE) examination have defined a detailed standard for medical professionals, particularly anesthesiologists, on how a TEE exam should proceed. Over the years, TEE has gained substantial popularity and emerged as a preferred monitoring modality to aid in perioperative management and decision making during hemodynamic instability situations or critical care settings. TEE training pathways and practice guidelines have been well established in western countries and many regions of the world. However, TEE training and practice information for anesthesiologists are lacking in China. As innovative technologies develop, other educational models have emerged to aid in obtaining competency in basic TEE exam. Hence, establishing a consensus on the ideal TEE training approach for anesthesiologists in China is urgently needed. Developing an effective curriculum that can be incorporated into an anesthesiology resident’s overall training is also necessary to provide knowledge and skills toward competency in basic TEE exam. With evolving medical system reforms and increasing demands for intraoperative hemodynamic monitoring to accommodate surgical innovations, anesthesiology professionals are increasingly obliged to perform intraoperative TEE exams in their current and future practices. To overcome obstacles and achieve significant progress in using the TEE modality to help in intraoperative management and surgical decision making, publishing basic TEE training guidelines for China’s anesthesiologists is an important endeavor.

perioperative transesophageal echocardiography: should new guidelines exist for limited echocardiography training

null

《医学前沿（英文）》 2012年第6卷第3期页码 332-337 doi: 10.1007/s11684-012-0212-8

摘要：

Bedside limited echocardiography, or focused cardiac ultrasound, continues to gain popularity in many emergency rooms, intensive care units, and operating rooms as a rapid method of assessing unstable patients. Effective monitoring of cardiovascular function in conditions like cardiac arrest or near-arrest is the crucial step to guide successful resuscitative efforts. Transesophageal echocardiography (TEE) has emerged as one of the preferred cardiac diagnostic and monitoring modalities in the intraoperative setting due to the fact that it is less invasive than many other monitors, is immediately accessible, and allows for continuous real-time monitoring of cardiac function. However, the minimum training requirements needed for the anesthesia provider to obtain the competency, knowledge, and skills for basic certification in perioperative TEE far exceed those developed for other medical specialties. We believe there is an urgent need to develop (1) practical guidelines for emergent perioperative TEE use for anesthesiologists and (2) a requisite educational curriculum to teach the basic skills necessary to aid in the diagnosis and treatment of cardiac arrest or near-arrest scenarios. The measures elucidated in this report summarize the efforts of the Department of Anesthesiology at the University of Florida in establishing the necessary steps to make this process not only practical, but accessible to all trainees. We hope that these collective efforts will provide more trainees the confidence in utilizing TEE to aid in establishing a diagnosis in critical situations.

Role of exercise training on insulin resistance and TNF-α in high-fat diet rats

Hui SUN MD, Xiuling DENG MM, Fangxi XIAO MD, Lulu CHEN MD, Huiqing LI MD,

《医学前沿（英文）》 2009年第3卷第4期页码 403-407 doi: 10.1007/s11684-009-0071-0

摘要： This study investigated the effect of exercise training on insulin resistance and serum and adipose TNF-α in high-fat diet-induced insulin-resistant rats. Thirty male Wistar rats were randomly divided into two groups: normal control group (NC; =8) that accepted normal chow and high-fat diet group (HF; =22) that fed on high-fat diet to induce insulin resistance model. The HF group was randomly assigned to two subgroups after 18 weeks: sedentary group (SE; =10) and exercise training group (ET; =12) that performed swimming exercise training for 6 weeks, while both groups continued high-fat diet. Changes of body weight, lipid profile, and fasting plasma glucose and insulin were measured. The insulin sensitivity index (ISI) was calculated. Serum concentration of TNF-α was detected by ELISA. The expression of TNF-α mRNA and protein in adipose tissue was examined by using real-time fluorescence quantitative polymerase chain reaction (PCR) and Western blot, respectively. After 18 weeks, compared with the NC group, body weight, blood lipid, glucose, and insulin in the HF group were significantly elevated, while the ISI decreased obviously, which suggested that insulin resistance appeared in the HF group. After exercise training for 6 weeks, compared with the SE group, both ISI and serum TNF-α concentration in the ET group were decreased significantly; however, the expression levels of TNF-α mRNA and protein in adipose tissue increased by 27.5% and 20.5%, respectively. In conclusion, exercise training ameliorates insulin resistance. The reduction of the level of serum TNF-α and the increased expression of TNF-α in adipose tissue by exercise training may be involved in this mechanism.

Kan ZHANG MM, Wei DONG MM, Ying-Yao CHEN MD,

《医学前沿（英文）》 2010年第4卷第2期页码 134-138 doi: 10.1007/s11684-010-0041-6

摘要： This article discusses the concept of health management and stresses that community health management should be the starting point of community health service, necessitating a paradigm shift from observing the treatment-oriented medical model to observing the prevention-and-health management-based medical model. Community health construction has entered a new phase, one which highlights the need to train general practitioners in practice-based life cycle health management. In addition, general practitioners should assume the mission of implementing community health management.

maize-based food-feed-energy systems to limited phosphate resources—a new Sino-German international research training

摘要：

Phosphate is supplied to agriculture by mining and fertilizer production, followed by different steps of phosphate utilization, including primary production, feed and food consumption, and conversion of biomass, with accumulation in soils, but little recycling and severe environmental losses. Phosphate is a limited essential nutrient, however, with very uneven distribution worldwide. Closing the cycle and reducing primary phosphate consumption are fundamental future challenges. Maize has a relatively high phosphate requirement. China and Germany together cover the whole range of maize production systems. The new Sino-German international research training group “Adaptation of Chinese and German maize-based food-feed-energy systems to limited phosphate resources” (AMAIZE-P) was initiated in 2018 as a joint venture of the China Agricultural University (Beijing, China) and the University of Hohenheim (Stuttgart, Germany). The interdisciplinary and complementary research is driven by the hypothesis that under phosphate limited conditions, high productivity and high phosphate use efficiency can be achieved simultaneously by adapting phosphate cycling and availability (sources) to the multipurpose phosphate demands (sinks) in maize-based food-feed-energy systems. The educational program for doctoral researchers in China and Germany includes joint block seminars, thematic field trips, case studies, methodological courses, doctoral researchers’ conferences, intercultural training sessions and personal training.

《信息与电子工程前沿（英文）》 2023年第24卷第10期页码 1375-1389 doi: 10.1631/FITEE.2300059

摘要：深度神经网络的鲁棒性引发了学术界和工业界的高度关注，特别是在安全攸关领域。相比于验证神经网络的鲁棒性是否成立，本文关注点在于给定扰动前提下的鲁棒神经网络训练。现有的代表性训练方法——区间边界传播（IBP）和CROWN-IBP——在较小扰动下表现良好，但在较大扰动下性能显著下降，本文称之为衰退风险。具体来说，衰退风险是指与较小扰动情况相比，IBP系列训练方法在较大扰动情况下不能提供预期的鲁棒神经网络的现象。为了缓解这种衰退风险，我们提出一种全局的、单调递减的鲁棒神经网络训练策略，该策略在每个训练轮次考虑多个扰动（全局鲁棒性训练策略），并将其相应的鲁棒性损失以单调递减的权重进行组织（单调递减鲁棒性训练策略）。实验证明，所提策略在较小扰动下能够保持原有算法的性能，在较大扰动下的衰退风险得到很大程度改善。值得注意的是，与原有训练方法相比，所提训练策略保留了更多的模型准确度，这意味着该训练策略更加平衡地考虑了模型的鲁棒性和准确性。

《信息与电子工程前沿（英文）》 2020年第21卷第9期页码 1267-1412 doi: 10.1631/FITEE.1900571

摘要： Opinion question (MRC) requires a machine to answer questions by analyzing corresponding passages. Compared with traditional MRC tasks where the answer to every question is a segment of text in corresponding passages, opinion question MRC is more challenging because the answer to an opinion question may not appear in corresponding passages but needs to be deduced from multiple sentences. In this study, a novel framework based on is proposed to address such problems, in which a new hybrid embedding training method combining text features is used. Furthermore, extra attention and output layers which generate auxiliary losses are introduced to jointly train the stacked recurrent . To deal with imbalance of the dataset, irrelevancy of question and passage is used for . Experimental results show that the proposed method achieves state-of-the-art performance. We are the biweekly champion in the opinion question MRC task in Artificial Intelligence Challenger 2018 (AIC2018).

Loss of monocarboxylate transporter 1 aggravates white matter injury after experimental subarachnoid hemorrhage in rats

《医学前沿（英文）》 2021年第15卷第6期页码 887-902 doi: 10.1007/s11684-021-0879-9

摘要： Monocarboxylic acid transporter 1 (MCT1) maintains axonal function by transferring lactic acid from oligodendrocytes to axons. Subarachnoid hemorrhage (SAH) induces white matter injury, but the involvement of MCT1 is unclear. In this study, the SAH model of adult male Sprague-Dawley rats was used to explore the role of MCT1 in white matter injury after SAH. At 48 h after SAH, oligodendrocyte MCT1 was significantly reduced, and the exogenous overexpression of MCT1 significantly improved white matter integrity and long-term cognitive function. Motor training after SAH significantly increased the number of ITPR2⁺SOX10⁺ oligodendrocytes and upregulated the level of MCT1, which was positively correlated with the behavioral ability of rats. In addition, miR-29b and miR-124 levels were significantly increased in SAH rats compared with non-SAH rats. Further intervention experiments showed that miR-29b and miR-124 could negatively regulate the level of MCT1. This study confirmed that the loss of MCT1 may be one of the mechanisms of white matter damage after SAH and may be caused by the negative regulation of miR-29b and miR-124. MCT1 may be involved in the neurological improvement of rehabilitation training after SAH.

摘要：由于边缘设备有限算力和边缘网络有限的无线资源，利用联邦边缘学习（federated edge learning, FEEL）训练机器学习模型通常非常耗时。本文研究了量化FEEL系统中训练时间最小化问题，其中异构边缘设备通过正交信道向边缘服务器发送量化后的梯度。采用随机量化对上传的梯度进行压缩，可减少每轮通信的开销，但可能会增加通信轮数。综合考虑通信时间、计算时间和通信轮数对训练时间进行建模。基于所提出的训练时间模型，描述了通信轮数和每轮延迟之间的内在权衡。具体地，分析了量化FEEL的收敛性。提出一种基于数据模型双驱动的拟合方法以得到精确的最优间隔，并在此基础上得到通信轮数和总训练时间的闭式表达式。在总带宽限制下，将训练时间最小化问题建模为量化级数和带宽分配的优化问题。本文通过交替求解量化优化子问题（通过连续凸近似方法求解）和带宽分配子问题（通过二分查找方法求解）解决这个问题。在不同学习任务和模型下，仿真结果证明了本文分析的有效性和所提优化算法性能接近最优。
