海南省三亚地区2019—2020年妊娠期糖尿病发生情况及与孕妇饮食行为的关系研究

目的调查海南三亚地区2019—2020年妊娠期糖尿病(GDM)发生情况并研究其与孕妇饮食行为的关系。方法以2019年1月—2020年12月在海南三亚地区2家医院产科建档行定期规范产前检查的孕妇为研究对象,调查孕妇的基本临床资料与饮食行为情况,采用单因素分析、多因素分析方法分析孕妇饮食行为与GDM发病的关系。结果 20 086名孕妇中,GDM患者3 173例,GDM发生率为15.80%。高龄(OR=3.812)、孕前体质量指数(BMI)高(OR=2.473、2.975)、有糖尿病家族史(OR=2.730)、甜食食用频率高(OR=1.394、1.723)、每日水果摄入量多(OR=1.342、1.387、1.458)、精制谷物比例高(OR=1.357)、高脂食品摄入频率高(OR=1.510)的孕妇发生GDM的可能性较大,日运动时间≥1 h(OR=0.435)的孕妇发生GDM的可能性较小。结论海南三亚地区GDM发生率较高,其发生与孕妇饮食行为有关,甜食与高脂食品摄入频率过高、每日水果摄入量过多、主食过于精制是GDM的危险因素,每日运动时间≥1 h是GDM的保护因素。     

珠海地区NRXN1和NLGN1基因多态性与儿童孤独症的关联性研究

目的 探索珠海地区NRXN1和NLGN1基因多态性与儿童孤独症易感性的关系,为孤独症的防治提供科学依据。方法 采用病例对照的研究方法,选取2011－2016年就诊于珠海市妇幼保健院的123例珠海地区的孤独症患儿和506例健康对照。采用口腔拭子采集口腔上皮细胞以提取DNA,采用Sequenom Mass Array platform分型技术对NRXN1基因上的rs1045881和rs11885824以及NLGN1上的rs9855544进行基因分型。结果 NRXN1基因上的rs1045881和rs11885824以及NLGN1上的rs9855544位点基因型分布在孤独症组和健康对照组比较,差异无统计学意义;但NLGN1基因上的rs9855544与NRXN1基因上的rs11885824存在基因与基因间的交互作用(预测准确率为0.480,交叉验证一致性为10/10,P=0.040)。结论 NRXN1基因上的rs1045881和rs11885824以及NLGN1上的rs9855544位点基因多态性可能与孤独症易感性没有关联,但NLGN1基因上的rs9855544与NRXN1基因上的rs11885824之间的交互作用可能是孤独症易感性的影响因素。     

新癀片用于口腔种植牙术后肿胀疼痛中的治疗效果观察

目的：探析口腔种植牙术后肿胀疼痛采取新癀片进行治疗的效果及对炎性因子的影响。方法：选取2015年1月至2019年12月北京中医药大学东直门医院收治的口腔种植牙术后肿胀疼痛患者300例作为研究对象，按照随机数字表法随机分为对照组和观察组，每组150例，对照组采用红霉素治疗，观察组采用新癀片联合红霉素治疗，比较2组患者术后肿胀和术后疼痛持续时间、牙槽骨吸收量、种植牙功能、种植体唇侧骨厚度、周围边缘骨吸收量、炎性反应因子水平、治疗优良率等指标。结果：与对照组比较，观察组术后肿胀持续时间、术后疼痛持续时间明显较短（P<0.05）；观察组种植牙功能评分等明显高于对照组（P<0.05）；观察组种植体唇侧骨厚度、周围边缘骨吸收量与对照组比较有明显差别（P<0.05）；观察组CPR、IL-6、PCT等炎性反应因子水平明显较低（P<0.05）；观察组治疗总有效率明显高于对照组（P<0.05）。结论：口腔种植牙术后肿胀疼痛应用新癀片进行治疗，能获得较为理想的效果，改善炎性反应因子水平，有着极大的推广价值。     

新形势下八年制医学教育的再思考

新形势下，健康中国建设和我国卫生事业发展迫切需要具有国际竞争力的医学科学家和领军人才。在现行医学教育体系中，培养具有国际竞争力的未来医学科学家和领军人才是八年制医学教育的必然选择。创新八年制医学人才培养模式应汲取长学制试办经验，直面现存问题，聚焦创新能力和创新精神，构建以研究为基础的八年制医学人才培养模式，确立“目标引领、厚植基础、面向临床、聚集创新”的办学原则，为我国卫生事业培养具有国际竞争力的未来领军人才。     

EuroGuiDerm Guideline on the systemic treatment of Psoriasis vulgaris – Part 1: treatment and monitoring recommendations

This evidence- and consensus-based guideline on the treatment of psoriasis vulgaris was developed following the EuroGuiDerm Guideline and Consensus Statement Development Manual. The first part of the guideline includes general information on the scope and purpose, health questions covered, target users and strength/limitations of the guideline. Suggestions for disease severity grading and treatment goals are provided. It presents the general treatment recommendations as well as detailed management and monitoring recommendations for the individual drugs. The treatment options discussed in this guideline are as follows: acitretin, ciclosporin, fumarates, methotrexate, adalimumab, apremilast, brodalumab, certolizumab pegol, etanercept, guselkumab, infliximab, ixekizumab, risankizumab, secukinumab, tildrakizumab and ustekinumab.     

Sex and gender differences in Alzheimer’s disease: current challenges and implications for clinical practice

Alzheimer’s disease (AD) is characterized by high heterogeneity in disease manifestation, progression and risk factors. High phenotypic variability is currently regarded as one of the largest hurdles in early diagnosis and in the design of clinical trials; there is therefore great interest in identifying factors driving variability that can be used for patient stratification. In addition to genetic and lifestyle factors, the individual’s sex and gender are emerging as crucial drivers of phenotypic variability. Evidence exists on sex and gender differences in the rate of cognitive deterioration and brain atrophy, and in the effect of risk factors as well as in the patterns of diagnostic biomarkers. Such evidence might be of high relevance and requires attention in clinical practice and clinical trials. However, sex and gender differences are currently seldom appreciated; importantly, consideration of sex and gender differences is not currently a focus in the design and analysis of clinical trials for AD. The objective of this position paper is (i) to provide an overview of known sex and gender differences that might have implications for clinical practice, (ii) to identify the most important knowledge gaps in the field (with a special regard to clinical trials) and (iii) to provide conclusions for future studies. This scientific statement is endorsed by the European Academy of Neurology.
