| 1 | Utilization of the Accident & Emergency Departments by Chinese elderly in Hong Kong显示文摘BACKGROUND: The epidemiological data on elderly patients attending Accident and Emergency Departments(AEDs) in Hong Kong is lacking. The study aimed to examine the epidemiology of geriatric patient visits to AEDs in Hong Kong, including demographic data and predictors of life-saving interventions(LSI) and admission.METHODS: A retrospective cross-sectional study of geriatric patients older than 64 years old attending three AEDs during the year 2012, with a sample of 1 200 patient visits recruited. The data were retrieved from the medical records of the respective hospitals. Descriptive characteristics of the visits were provided. Multivariate logistic regression was performed to evaluate the predictors of LSI and hospital admission.RESULTS: The mean age of the patients was 79.1 years. Totally 49.7% of the patients were male. 'Diseases of the respiratory system' was the commonest diagnosis in AEDs as well as that required admission. The admission rate was 56.8%. Logistic regression demonstrated that dependent activity of daily living(ADL), arrival by ambulance, and the higher number of co-morbidities were predictors of LSI, while advanced age, dependent ADL, institutionalized patients, arrival by ambulance, and higher number of co-morbidities were predictors of hospital admission.CONCLUSIONS: Ageing population is creating an imminent burden on the emergency service in Hong Kong. Previously unavailable epidemiological information about geriatric attendance to AEDs was described. This forms the basis for development of future studies concerning the medical services on this specific group of patients. | Wai Lam Yip Kit Ling Fan Chun Tat Lui Ling Pong Leung Fu Ng Kwok Leung Tsui | 2015 | World Journal of Emergency Medicine2015，6，4： | 3 |
| 2 | Recent advances in RNA structurome显示文摘RNA structures are essential to support RNA functions and regulation in various biological processes. Recently, a range of novel technologies have been developed to decode genome-wide RNA structures and novel modes of functionality across a wide range of species. In this review, we summarize key strategies for probing the RNA structurome and discuss the pros and cons of representative technologies. In particular, these new technologies have been applied to dissect the structural landscape of the SARS-CoV-2 RNA genome. We also summarize the functionalities of RNA structures discovered in different regulatory layers-including RNA processing, transport, localization, and mRNA translation-across viruses, bacteria, animals, and plants. We review many versatile RNA structural elements in the context of different physiological and pathological processes(e.g., cell differentiation, stress response, and viral replication). Finally, we discuss future prospects for RNA structural studies to map the RNA structurome at higher resolution and at the single-molecule and single-cell level, and to decipher novel modes of RNA structures and functions for innovative applications. | Bingbing Xu Yanda Zhu Changchang Cao Hao Chen Qiongli Jin Guangnan Li Junfeng Ma Siwy Ling Yang Jieyu Zhao Jianghui Zhu Yiliang Ding Xianyang Fang Yongfeng Jin Chun Kit Kwok Aiming Ren Yue Wan Zhiye Wang Yuanchao Xue Huakun Zhang Qiangfeng Cliff Zhang Yu Zhou | 2022 | Science China(Life Sciences)2022，65，7： | 1 |
| 3 | An ultra low-input method for global RNA structure probing uncovers Regnase-1-mediated regulation in macrophages显示文摘To enable diverse functions and precise regulation,an RNA sequence often folds into complex yet distinct structures in different cellular states.Probing RNA in its native environment is essential to uncovering RNA structures of biological contexts.However,current methods generally require large amounts of input RNA and are challenging for physiologically relevant use.Here,we report smartSHAPE,a new RNA structure probing method that requires very low amounts of RNA input due to the largely reduced artefact of probing signals and increased efficiency of library construction.Using smartSHAPE,we showcased the profiling of the RNA structure landscape of mouse intestinal macrophages upon inflammation,and provided evidence that RNA conformational changes regulate immune responses.These results demonstrate that smartSHAPE can greatly expand the scope of RNA structure-based investigations in practical biological systems,and also provide a research paradigm for the study of post-transcriptional regulation. | Meiling Piao Pan Li Xiaomin Zeng Xi-Wen Wang Lan Kang Jinsong Zhang Yifan Wei Shaojun Zhangas Lei Tang Jianghui Zhu Chun Kit Kwok Xiaoyu Hu Qiangfeng Cliff Zhang | 2022 | Fundamental Research2022，2，1： | 0 |
