乌司他丁与连续性血液净化联合治疗热射病的效果及对机体炎性反应影响研究

目的 分析乌司他丁与连续性血液净化联用对热射病患者所产生的影响。方法 选取2017年5月—2019年2月在海南医学院第二附属医院进行治疗的88例热射病患者作为研究对象,将其分为研究组和常规组,常规组患者接受常规治疗,研究组患者在常规治疗基础上,将乌司他丁与连续性血液净化联用。分析两种治疗措施的效果。结果 治疗前两组患者的IL-17、TNF-α、cTnⅠ、β₂-MG、PT、D-D、ET和TM水平,差异无统计学意义（P>0.05）。经治疗两组患者的上述指标水平都表现出下降的趋势,相对于常规组,研究组患者下降水平更明显,差异具有统计学意义（P<0.05）。研究组治疗的总有效率为95.5%,高于常规组的72.7%,差异具有统计学意义（P<0.05）。结论 运用乌司他丁与连续性血液净化联用的疗法对热射病患者进行治疗,可获得十分理想的治疗效果,可在临床工作中推广。

健康支持性环境对四川农村人群的不同血压水平的影响分析

目的 探讨健康支持性环境中的不同特征变量对四川省农村人群的不同血压水平的影响。方法 采用多阶段整群抽样的方法，随机抽取四川省7个县（区）8400名的18岁以上常住居民为调查对象。问卷调查一般人口学特征、身体活动行为特征和环境等信息。采用标准方法测量身高、体重、腰围和血压。采用无序多分类logistic回归分析。结果 本调查人群中共检出正常高值血压者4270例，检出率为50.83%，标化率为37.02%，平均年龄（56.22±14.89）岁；高血压患者1498例，检出率为17.83%，标化率为7.92%，平均年龄（65.26±11.28）岁。无序多分类logistic回归结果显示，住宿环境好、获得运动方面的健康信息和参与中等强度活动150Symbol~A@300min/周是正常高值血压和高血压人群的共同保护因素；住宿便利（OR=0.789, 95%CI:0.649~0.958, P=0.017）、医疗服务可及性便利（OR=0.686, 95%CI:0.509~0.924, P=0.013）、对健身步道和健身广场满意为高血压人群的保护因素。结论 多途径合理构建健康支持性环境，对农村正常高值血压者和高血压患者具有保护作用，对遏制农村高血压的流行现状起到一定作用。     

Rural–urban disparities in knowledge,behaviors, and mental health during COVID-19 pandemic: A community-based cross-sectional survey

To examine the knowledge level, behaviors, and psychological status of the Chinese population during the COVID-19 pandemic, and to explore the differences between urban and rural areas.We carried out a cross-sectional survey of the knowledge, behaviors related to COVID-19, and mental health in a probability sample of 3001 community residents in 30 provinces or districts across China from February 16–23, 2020. Convenience sampling and a snowball sampling were adopted. We used General Anxiety Disorder (GAD), the 9-item Patient Health Questionnaire (PHQ-9), and knowledge and behaviors questionnaire of community residents regarding COVID-19 designed by us to investigate the psychological status, disease-related knowledge, and the behavior of Chinese urban and rural residents during the pandemic.The average score of anxiety and depression among urban residents was 9.15 and 11.25, respectively, while the figures in rural areas were 8.69 and 10.57, respectively. There was a statistically significant difference in the levels of anxiety (P < .01) and depression (P < .01). Urban participants reported significantly higher levels of knowledge regarding COVID-19 in all aspects (transmission, prevention measures, symptoms of infection, treatment, and prognosis) (P < .01), compared to their rural counterparts. While a majority of respondents in urban areas obtained knowledge through WeChat, other apps, and the Internet (P < .01), residents in rural areas accessed information through interactions with the community (P < .01). Urban residents fared well in exchanging knowledge about COVID-19 and advising others to take preventive measures (P < .01), but fared poorly in advising people to visit a hospital if they displayed symptoms of the disease, compared to rural residents (P < .01). Regression analysis with behavior showed that being female (OR = 2.106, 95%CI = 1.259–3.522), aged 18 ≤ age < 65 (OR = 4.059, 95%CI = 2.166–7.607), being satisfied with the precautions taken by the community (OR = 2.594, 95%CI = 1.485–4.530), disinfecting public facilities in the community (OR = 2.342, 95%CI = 1.206–4.547), having knowledge of transmission modes (OR = 3.987, 95%CI: 2.039, 7.798), symptoms (OR = 2.045, 95%CI = 1.054–4.003), and outcomes (OR = 2.740, 95%CI = 1.513–4.962) of COVID-19, and not having anxiety symptoms (OR = 2.578, 95%CI = 1.127–5.901) were positively associated with affirmative behavior in urban areas. Being married (OR = 4.960, 95%CI = 2.608–9.434), being satisfied with the precautions taken by the community (OR = 2.484, 95%CI = 1.315–4.691), screening to ensure face mask wearing before entering the community (OR = 8.809, 95%CI = 2.649–19.294), and having knowledge about precautions (OR = 4.886, 95%CI = 2.604–9.167) and outcomes (OR = 2.657, 95%CI = 1.309–5.391) were positively associated with acceptable conduct in rural areas.The status of anxiety and depression among urban residents was more severe compared to those living in rural areas. There was a difference in being positively associated with constructive behaviors between rural and urban areas.
