Objective:To investigate the incidence, risk factors, and outcomes of falls among the elderly community population in Beijing.Methods:A cross-sectional survey was conducted using stratified multistage random sampling to select urban and rural residents aged 65 years and older in Beijing. Mortality data was collected after the baseline survey for 5 years. The incidence of falls was weighted based on the composition ratios of age and gender from the 2010 Nation-wide Population Census of Beijing. A logistic regression model was used to analyze the impacts of demographic sociology of common chronic diseases on fall occurrence. The Cox proportional hazards regression model was used to analyze the fall and 5-year survival association.Results:A total of 2 968 participants completed the questionnaire, at cross-sectional survey, with an average age of (73.2±6.0) years, and 1 581 (53.8%) participants were female. Three hundred and sixty-one individuals experienced a fall within the past year. Among those who fell, 64 (17.7%) fell twice, and 95 (26.6%) fell three or more times. Of them, 14.4% (52) had post-fall fractures, with the wrist, knee, and hip being the most common fracture sites, accounting for 25.0%, 17.3%, and 15.4%, respectively. The weighted fall incidence was 12.4% (95% CI: 11.2%-13.5%). Aging, being female, and living in rural areas were more likely to fall. Logistic regression analysis showed that after adjusting for age, gender, and urban-rural status, the risk of falls for those living alone ( OR=1.48, 95% CI: 1.08-2.04) or living with children/grandchildren ( OR=1.51, 95% CI: 1.15-1.97) were significantly higher than those living with their spouse. In addition, the risk of falls was elevated significantly among the elderly with hypertension, diabetes, stroke, dementia, depression status, urinary incontinence, arthritis, insomnia, vision, and hearing loss, dependence on activities of daily living (ADL), general and poor self-rated health (SRH). The Cox proportional hazard regression model revealed that the 5-year risk of death increased by 65% ( HR=1.65, 95% CI: 1.29-2.11) for those who experienced a fall, which increased with fall frequency. This elevated risk persisted after adjusting for chronic conditions, ADL, and SRH. Conclusions:Ageing, female, living in rural regions, having common chronic diseases, dependence on ADL, general and poor SRH, living alone or living with children/grandchildren were associated with the elevated fall risk. The occurrence of fall was seasonal. The most common short-term adverse consequence after a fall was fractures, while the long-term effect was an increased risk of death.

Objective:To investigate the prevalence and mortality of dementia and assess the impact of geriatric syndromes (GS) on the risk for dementia and death in elderly population in Beijing.Methods:A cross-sectional survey was conducted in the elderly population aged ≥65 years and selected by a multi-stage sampling in Beijing during 2013-2015. Cognitive function was screened using the Chinese Revised Version of the Mini-Mental State Examination (MMSE). Then, neurological examination and psychiatric assessment were performed for those with the MMSE score lower than the cut-off value. The information about GS prevalence was also collected. The study also collected death records for all individuals from baseline until December 31, 2019. Based on the age and gender distribution from Beijing data of the 2010 Six th National Population Census, the dementia prevalence in the study population was directly standardized. Logistic regression analysis was used to evaluate the association of different forms of dementia with GS, and Cox proportional hazards regression model was used to estimate the hazard ratio ( HR) and 95% CI of death. Results:During 2013-2015, a total of 2 935 individuals completed dementia assessments, of which 167 were diagnosed with dementia. The standardized prevalence of dementia was 5.9% (95% CI: 5.0%-17.4%). The individuals with Alzheimer's disease (AD) and vascular dementia (VaD) accounted for 58.7% and 28.1% of total individuals with dementia, respectively. Aging, lower education level, urinary incontinence, and fall were risk factors for AD, while disability of activity of daily life dependence, hypertension, and stroke were found to be risk factors for VaD. After a median follow-up of 5.44 person-years, 399 deaths were recorded. The 5-year mortality risk was 2.87 (95% CI: 1.92-4.17) times and 4.93 (95% CI: 3.23-7.53) times higher for the elderly individuals with AD and VaD, respectively, compared to non-demented individuals. After adjusting for demographic, GS, and cardiovascular risk factors, the mortality risk in the elderly individuals with AD showed no significant difference compared with non-demented individuals ( HR=1.32, 95% CI: 0.89-1.97), while the mortality risk in those with VaD was 2.46 (95% CI: 1.49-4.05) times higher than that in non-demented individuals. Conclusions:The prevalence of dementia in Beijing increased significantly in the context of population aging, especially the prevalence of AD. The presence of GS increased the risks for AD and VaD, as well as the risk for death. Close attention needs to be paid to GS management in dementia prevention in elderly population.

[摘 要] 目的：探究微小RNA-504（miRNA-504）在胃癌（GC）组织中的表达水平及其对GC细胞生物学行为的调控机制。方法：收集2020年6月至2020年12月期间三亚中心医院外科收治的48例胃癌患者的肿瘤组织及癌旁组织标本，qPCR检测组织中miR-504、肿瘤蛋白53诱导型核蛋白1（tumor protein 53-induced nuclear protein 1，TP53INP1）mRNA的水平，WB法检测TP53INP1水平。体外培养人胃癌细胞BGC-823，分为对照组（正常培养的BGC-823细胞）、miR-504 mimic组、mimic-NC组、miR-504 inhibitor组、inhibitor-NC组、miR-504 inhibitor+si-NC组、miR-504 inhibitor+si-TP53INP1组，qPCR检测细胞中miR-504和TP53INP1 mRNA的表达，MTT法、流式细胞术、划痕实验和Transwell侵袭实验分别检测各组细胞的增殖、凋亡、迁移和侵袭能力，WB法检测各组细胞中增殖、迁移和侵袭相关蛋白（Cyclin D1、E-cadherin、MMP-2、MMP-9）以及TP53INP1的表达。双荧光素酶报告基因实验进一步验证miR-504与TP53INP1 mRNA的靶向关系。结果：与癌旁组织相比，胃癌组织中miR-504的表达显著升高（P<0.05），而TP53INP1 mRNA和蛋白表达水平显著降低（P<0.05或P<0.01），miR-504和TP53INP mRNA两者的表达呈负相关（P<0.01）。与对照组相比，miR-504 mimic组BGC-823细胞中miR-504的表达显著升高（P<0.05）、TP53INP1 mRNA和蛋白的表达显著降低（均P<0.05），且细胞增殖率、划痕愈合率、侵袭入Transwell小室下层的细胞数量，Cyclin D1、MMP-2、MMP-9蛋白表达均显著增加，细胞凋亡率和E-cadherin蛋白表达均显著降低（均P<0.05）。转染miR-504 inhibitor能显著下调BGC-823中miR-504的表达、上调TP53INP1 mRNA和蛋白的表达，抑制细胞的增殖、迁移与侵袭能力而促进细胞凋亡（均P<0.05）；而下调TP53INP1的表达可明显减弱miR-504下调对BGC-823细胞增殖、迁移与侵袭的抑制作用（P<0.01）。miR-504高表达能明显抑制野生型TP53INP1质粒的荧光素酶活性（P<0.05）。结论：miR-504在胃癌组织中呈高表达，下调miR-504可抑制胃癌BGC-823细胞的恶性生物学行为而促进其凋亡，其作用机制可能与靶向调控TP53INP1的表达有关。

Objective To investigate the epidemiological characteristics of a family clustering of COVID-19. Methods Field epidemiological survey was conducted. Result Case 1 of the long-term residents from Hubei province was the source of infection of this family clustering. There were 6 cases (from case 2 to case 7) infected in the whole incubation period. The incubation period was more than 14 days for 3 of the second-generation cases. Routes of transmission include respiratory droplets (from case 1 transmitted to case 6, from case 1 to her family members) and closecontact (from case 1 to other cases in her family). All the age groups were generally susceptible, while elderly were easier to progress to critically ill. Besides respiratory symptoms, there were also gastrointestinal symptoms, of which diarrhea was the most common one. Conclusion Family clustering had been an important part for COVID-19 cases.

Objective: To investigate the prevalence characters of peripheral artery disease (PAD) and associated factors among people aged 35 and above in Beijing. Methods: This was a cross-sectional study. A total of 5 208 community-based individuals aged equal and above 35 in Beijing were chosen with stratified multistage random sampling method. Structure questionnaire was used to collected the information of demographic factors, habits and chronic disease history. Ankle brachial blood pressure was detected and ankle brachial index (ABI) was calculated. ABI was used to diagnose PAD (ABI≤0.90). Based on the 2010 Beijing Municipal Population Census, the age-and gender-specific weight-adjusted sample was acquired to estimate the prevalence of PAD and corresponding 95% confidence intervals (CI). Multivariate logistic regression analysis was performed to estimate the associated factors of PAD. Results: The age-and sex-standardized prevalence of PAD was 3.84% (200/5 208, 95%CI 3.32%-4.36%). There was no significant difference between male and female (3.83%(102/2 664, 95%CI 3.10%-4.56%) vs. 3.85% (98/2 544, 95%CI 3.10%-4.60%), P=0.965). The prevalence of PAD in urban was higher than that in rural (4.34% (163/3 755, 95%CI 3.69%-4.99%) vs. 2.55% (37/1 453, 95%CI 1.74%-3.36%), P=0.001). Furthermore, the prevalence of PAD increased with age (P_trend<0.01), and the difference between genders did not change with ageing (all P>0.05). In addition, age (OR=1.03, 95%CI 1.01-1.04), urban (OR=1.52, 95%CI 1.08-2.12), smoking (OR=1.83, 95%CI 1.29-2.59), hypertension (OR=1.61, 95%CI 1.17-2.22) and diabetes (OR=1.44, 95%CI 1.08-1.93) were related with increased risk of PAD in logistic regression analysis models. Conclusions The prevalence of PAD increases with age in Beijing and there are significant difference between urban and rural on prevalence of PAD. Age, urban, smoking, hypertension and diabetes are related with increased risk of PAD.
