目的 通过对南昌市周围农村居民、城市居民及教师群体进行卒中筛查，了解本地区卒中高危人群 在不同群体的分布情况，探讨卒中筛查的意义及规范化管理后的效果。 方法 对不同社区的居民，通过填写调查问卷和体检进行卒中危险因素评估；对筛查出的高危人群 进行生活方式和（或）药物干预等规范化管理，3年后再次对其进行危险因素评估，评价干预效果。 结果 农村居民746人参与筛查，高危人数177人（23.72%），通过调查问卷进行的卒中风险评估 平均得分（3.30±0.59）分；城市居民1005人参与筛查，高危人数281人（27.96%），风险评估平均 得分（3.68±0.78）分；教师群体1359人参与筛查，高危人数172人（12.66%），风险评估平均得分 （3.21±0.51）分。3年内，农村居民有5人新发卒中，5名卒中患者死亡，1名患者因其他疾病死亡，19人 通过干预由高危人群转为非高危人群，卒中风险评估平均得分（2.97±0.55）分；城市居民有5人新 发卒中，5人再发卒中而死亡，88人由高危人群转为非高危人群，风险评估平均得分为（2.75±0.72） 分；教师群体有2人新发卒中，1人再发卒中死亡，59人通过干预由高危人群转为非高危人群，风险 评估平均得分（2.81±0.73）分。一共有51人因症状性颅内或颅外动脉狭窄行支架干预治疗，8人因 颅内动脉瘤行动脉瘤栓塞术。农村居民危险因素排名前三位的分别为血脂异常（72.88%）、高血压 （58.19%）、肥胖（46.33%），城市居民排名前三位的为高血压（77.22%）、血脂异常（58.36%）、肥 胖（54.80%），教师群体排名前三位的为缺乏体育锻炼（86.05%）、血脂异常（84.84%）、高血压 （62.79%）。对高危人群进行规范化管理，经过干预后每个群体的卒中风险评估分值都显著下降（P ＜0.001）。 结论 不同群体的卒中高危人群患病率不同，高危因素的构成比不同，可能与饮食结构、文化水平 等有关；每个群体高危人群经过规范化管理，都取得了良好的干预效果。社区卒中筛查是早期发现 卒中高危人群的有效方法，对高危人群实施社区规范化管理，能够有效地控制和减少危险因素，减 少卒中的发生。 Abstract: Objective To investigate the effectiveness of community-based stroke risk factors screening and standardized management in Nanchang city, and to understand the prevalence of high risk population of stroke in different population in Nanchang area. Methods Stroke risk factors were evaluated by questionnaire and physical examination in rural inhabitants, urban inhabitants, and teachers in different communities of in Nanchang city. The people who had more than three risk factors were considered as high-risk people of stroke. The high-risk people were given 3-year of standardized management including changing the life style and/or drugs intervention. The risk factors were re-assessed after 3 years to evaluate the effect of these intervention.Results Of 746 rural inhabitants who participated in the screening, 177 (23.72%) were at high risk, and the mean score of risk factor assessment by questionnaire was (3.30±0.59). Of 1005 urban inhabitants who participated in the screening, 281 (27.96%) were at high risk, and the mean score of risk factor assessment was (3.68±0.78). Of 1359 teachers having undergone the screening, 172 (12.66%) were at high risk, and the mean score was (3.21±0.51). All the high-risk subjects were given standardized management, and their risk factors and prognosis including new-onset stroke and death were re-evaluated after 3 years. After 3 years, of the rural inhabitants, 5 people occurred new-onset stroke, 5 died from stroke, 1 died from other disease, 19 high-risk persons improved into non-high risk ones by intervention, and their mean score of risk factor assessment dropped to (2.97±0.55) (P

The digital transformation of city is in line with the“dual circulation”development needs, the implementation of national strategic deployment, to meet the needs of the city’s own development, aiming to reshape the city development form with technologydriven mechanism, platform governance mechanism, data value-driven mechanism, and to promote the digital transformation of life, governance, economy, and other aspects. This paper constructs a comprehensive analysis framework of digital transformation of city from the perspectives of what, why, who, and how, and explores the internal mechanism of digital transformation of city through the practice in Shanghai. At present, the practice of digital transformation of city in China still faces challenges in digital concepts, top-level design, policies and institutions, digital governance, and digital inclusion. In order to comprehensively promote the digital transformation of city, this study proposes optimization paths such as optimizing top-level design with concept innovation, technology and system twoside drive, strengthening data open sharing, governance and application, and promoting multi-agent participation and multi-field transformation.
