膝骨关节炎中医药系统生物学研究述评＊

膝骨关节炎（Knee Osteoarthritis， KOA）属于临床难治性疾病，其高发病率、高致残性给国民健康、社会发展造成了沉重的负担。在这种不利局面下，中医药在KOA的临床防治上发挥了巨大的作用，其根据“辨证施治”理念的指导对患者采用个体化治疗往往能够取得良好的临床疗效 。然而中医学在传统认知上作为经验医学的集成，现有的KOA中医药基础研究结果尚未完全阐明其客观化、现代化的属性，阻碍了中医药防治KOA科学内涵的揭示以及全面、系统的临床研究的开展和新药研发，如何开展完善、合理、可行的基础研究以进行KOA中医药客观化和现代化探索成为研究者不得不解决的重大难题。随着系统生物学知识结构和研究手段的完善与更新，其与中医药的结合已经成为阐释并创新中医药理论内核、突破中医药研究瓶颈的重要方法。本文通过总结、分析目前KOA中医药基础研究的现状与不足，突出系统生物学在目前KOA中医药研究中的关键作用及应用趋势，以期为今后KOA的中医药研究和发展提供新的思路与对策。     

Impacto del primer año de tratamiento sustitutivo renal en la hospitalización de una comunidad autónoma

Introduction and objectivesChronic kidney disease has a high prevalence and economic impact, and an increased risk of hospitalization. Although there are public regional and country registries, we have not found references to estimate the impact of renal replacement therapy (RRT) on hospital admissions.MethodsWe obtained authorization from the ethics committee and health authorities to integrate the REMER [Madrid Kidney Disease Registry] (2013-2014) and Minimum Basic Data Set (2013-2015) databases and to analyze the admissions during the first year of RRT.Results767 patients started RRT in all the hospitals of our region across all RRT modalities. More than a third of the patients start dialysis during a hospital admission. This unplanned start, more common in HD than PD, shows relevant differences in patient profile or admission characteristics.Without considering this initial episode, almost 60% of patients were admitted during their first year. The hospitalization rate was 1.2 admissions/patient, higher in HD than in TX or PD; the mean length of stay was 8.6 days.The estimated cost of admissions during the first year is €12,006/patient. Our analysis ensures the exhaustive inclusion of all episodes and accurate estimation based on the discharge form.ConclusionThe impact of RRT on hospitals has been underestimated and is very relevant when calculating the total cost of RRT. Results from other countries cannot be extrapolated due to differences in the health system and patient profile. The integration of clinical databases could open up an opportunity that needs only institutional support for its development.     

基于超效率DEA的天津市基本公共卫生配置资源效率研究

评价天津市各辖区基本公共卫生服务的资源配置效率,寻求有效的资源配置措施和方法,为进一步优化卫生资源配置提供参考依据。方法利用数据包络分析,对天津市16辖区的基本公共卫生服务进行效率评价。结果天津市基本公共卫生服务的资源配置效率整体不高,仅有5辖区达到了规模最优,多数区非DEA有效,且投入过剩与产出不足并存。结论为了达到最优的基本公共卫生服务效率,政府及各级基本公共卫生服务机构必须有效地完善、落实相关政策,优化资源投入结构,统筹地区差异,加强资源供给管理,提高资源利用效率。     

"双固一通"艾灸法对糖尿病及糖尿病周围神经病变大鼠海马BDNF和NT-3蛋白的影响

目的观察“双固一通”艾灸法对糖尿病DM 及糖尿病周围神经病变(DPN)大鼠血糖及海马中神经营养因子(BDNF)和神经营养素-3(NT-3)蛋白的影响。方法75只雄性SD大鼠随机分为A组、B组、C组、D组和E组,每组15只。A组为正常对照组,不进行任何干预,B组为DM模型组,造模后不行艾灸干预;C组为DM艾灸治疗组,采用艾条悬灸;D组为DPN模型组,造模后不行艾灸干预;E组为DPN艾灸治疗组,采用艾条悬灸。于造模后72 h、4周治疗结束后和8周治疗结束后空腹尾静脉采血测血糖,于4周治疗结束后和8周治疗结束后,用免疫组化试验方法检测各组大鼠海马中BDNF和NT-3蛋白表达情况。结果B组、D组与A组血糖水平比较,差异有统计学意义(P<0.05),C组与B组比较,大鼠血糖水平降低(P<0.05);E组与D组比较,大鼠血糖水平降低(P<0.05)。B组、D组大鼠海马BDNF及NT-3免疫阳性神经元平均光密度值较A组明显减少(P<0.05);与B组比较,C组大鼠BDNF及NT-3免疫阳性神经元平均光密度值明显增加(P<0.05);与D组比较,E组大鼠BDNF及NT-3免疫阳性神经元平均光密度值明显增加(P<0.05)。结论“双固一通”艾灸法不仅可以起到明显的降糖效果,还可通过影响BDNF和NT-3蛋白的产生,保护糖尿病大鼠的感觉神经元,并对糖尿病及并发症周围神经病变起到治疗作用。     

新冠疫情下留学生医学基础课网上教学探索与实践

目的探讨新冠疫情下留学生医学基础课程网上授课的手段、方法和效果,以期在"停课不停学"下保障教学质量。方法利用雨课堂、企业微信和慕课等技术手段完成理论课的教学任务,同时通过随堂测试和问卷对教学效果进行评估。结果前期开展线上教学的问题主要集中在教学时差、缺少课堂互动、实践性课程的取消三个方面。因此,我们相应采取了录播课程、增加互动形式以及推迟实践性课程的方式,帮助学生渡过难关。结论现代化的网络教学方法比较受留学生的欢迎,同时多样化的教学方式满足了学生的不同需求。     

Effectiveness of simplified 15-min refresher BLS training program: A randomized controlled trial

ObjectivesTo evaluate the long-term effectiveness of 15-min refresher basic life support (BLS) training following 45-min chest compression-only BLS training.MethodsAfter the 45-min chest compression-only BLS training, the participants were randomly assigned to either the refresher BLS training group, which received a 15-min refresher training 6 months after the initial training (refresher training group), or to the control group, which did not receive refresher training. Participants’ resuscitation skills were evaluated by a 2-min case-based scenario test 1 year after the initial training. The primary outcome measure was the number of appropriate chest compressions during a 2-min test period.Results140 participants were enrolled and 112 of them completed this study. The number of appropriate chest compressions performed during the 2-min test period was significantly greater in the refresher training group (68.9 ± 72.3) than in the control group (36.3 ± 50.8, p = 0.009). Time without chest compressions was significantly shorter in the refresher training group (16.1 ± 2.1 s versus 26.9 ± 3.7 s, p < 0.001). There were no significant differences in time to chest compression (29.6 ± 16.7 s versus 34.4 ± 17.8 s, p = 0.172) and AED use between the groups.ConclusionsA short-time refresher BLS training program 6 months after the initial training can help trainees retain chest compression skills for up to 1 year. Repeated BLS training, even if very short, would be adopted to keep acquired CPR quality optimal (UMIN-CTR UMIN 000004101).     

Incidence of community-acquired pneumonia in urban China: A national population-based study

BackgroundCommunity-acquired pneumonia (CAP) is one of the major global health problems worldwide. However, the epidemiological information of CAP is limited in China. This study aimed to estimate the incidence rate of CAP and describe the epidemiologic characteristics among the Chinese population.MethodsWe conducted a retrospective analysis of CAP incidence using the Chinese Urban Basic Medical Insurance database of 23 provinces in 2016, which covered 427.52 million urban beneficiaries of all age groups in Mainland China. CAP episodes were identified using a diagnosis-term-derived algorithm, and multiple CAP records of one single person within 90 continuous days were considered as one single episode. The incidence rates were calculated and described by sex, age, region, and season.ResultsA total of 1.42 million patients were identified as having one or more CAP episodes, and finally a sum of 1.48 million CAP episodes were counted. The overall incidence of CAP was 7.13 (95% CI: 6.11–8.15) per 1000 person-years, in males 7.32 (95% CI: 6.28–8.35) and females 6.93 (95% CI: 5.92–7.94) per 1000 person-years, respectively. The incidence varied by age with a U-shaped curve peaking in children aged < 5 years old [65.80 (95% CI: 62.52–69.08)] and elderly population aged ≥ 80 years old [14.98 (95% CI: 13.63–16.34)]. The incidence varied markedly by regions. Furthermore, the rate showed a clear seasonal trend, which peaked in spring, decreased in summer and autumn, and re-ascended in winter.ConclusionThis study reveals a relatively high level of CAP incidence in China. These findings provide baseline data for establishing effective prevention strategies, targeted at susceptible populations, regions, and seasons in China.
