ABSTRACT
Alzheimer's disease (AD) is the most common neurodegenerative disease that causes dementia among elderly people. The pathogenesis of AD is still unclear, and currently approved drugs only provide symptomatic benefits and do not prevent or delay progressive neurodegeneration. Meanwhile, potential drugs in development are facing great challenges in clinical translation. Therefore, finding effective treatment for the unmet clinical needs of AD is of great economic value and social significance. In this review, we will summarize the current models and pharmacodynamics evaluation methods of anti-AD drug based on the recent studies at home and abroad, and provide reference for drug development in AD at nonclinical stage.
ABSTRACT
Amyotrophic lateral sclerosis (ALS) is among the most common type of motor neuron diseases, and its pathogenesis remains unclear. In recent years, our understanding of the genetic basis of ALS has led to the development of various ALS disease models, which allow for screening of ALS-related drugs and treatment methods. This review focuses on the research progress of ALS, summarizes the systems of commonly used experimental animal models, including transgenic animals, gene knockout approaches and autonomous animal models, points to the problems needing attention in standardized ALS non-clinical research, and proposes the criteria for selection of standardized R&D model.
ABSTRACT
Objective To realize leap-forward development in hospital informatization with the cloud hospital construction in Xiamen Third Hospital taken as an example.Methods The concept of Health Medical Cloud in Xiamen was introduced,and the advantages,risks,establishment of safety protection unit,difficulty and etc were analyzed during the cloud hospital construction.Results The cloud hospital enhanced hospital efficiency and medical service greatly,and the objectives were fulfilled for the cloud hospital.Conclusion The cloud hospital saves the costs for construction,running and maintenance,shortens the period for system construction,enhances hospital informatization.

ABSTRACT
Translating of scientific advances into clinical practice is a major challenge in the stroke research field in the past decades. There were many reasons involved:animal models might not accurately capture all aspects of clinical stroke in humans, the blind and randomized design principle was not closely followed, the inclusion and exclusion criteria was not previously established, sample size was inadequate, endpoint was not scientific nor blindly assessed, inadequate reporting of data and statistical flaws. To bridge the gap between experimental and clinical research, international consortia have attempted to establish standardized guidelines for study design and data report, which include optimizing animal models as well as experimental design, using innovative approaches to assess endpoint, making raw data and negative results available, establishing prior registration mechanism, conducting multicenter preclinical randomized controlled trials (pRCTs), systematic reviews and meta-analysis of preclinical studies, evolving the original focus on neuroprotection into a broader consideration of the role of neurovascular unit and ischemic cascade.
