焦虑抑郁状态对智齿冠周炎复发的影响

 目的 探讨焦虑抑郁状态对非外科手术治疗的智齿冠周炎复发的影响。方法 选择就诊于中日友好医院口腔医学中心的首发非外科治疗的智齿冠周炎患者,通过发放电子问卷收集如下信息:人口学信息、焦虑量表(GAD-7)和抑郁量表(PHQ-9)。半年后对随访患者的复发情况进行统计,采用多因素logistic回归分析智齿冠周炎复发与患者发病时情绪状态的关系。结果 共收集568份有效问卷,其中7.0%患者存在焦虑状态(GAD-7≥10),13.7%存在抑郁状态(PHQ-9≥10),半年后随访智齿冠周炎的复发率为11.4%。分析智齿冠周炎6个月后复发情况发现,男性的风险低于女性(OR=0.416,P＜0.05),焦虑增加了智齿冠周炎的复发风险(OR=1.124,P＜0.05)。结论 口腔医师应关注患者焦虑抑郁情绪状态,有助于智齿冠周炎的预防和治疗。

Psychological factors and oral health during initial outbreak of COVID-19 in China: A cross-sectional study

ObjectivesTo investigate associations between oral health and psychological factors (i.e., depression, anxiety, and resilience) in a group of Chinese individuals who had sought an intervention online during the COVID-19 pandemic.MethodsFor this cross-sectional study, online questionnaires were created using online survey software from set items of instruments commonly used to assess depression, anxiety, and resilience combined with an oral health survey. The study was conducted from March 13 to 16, 2020.Results568 participants (188 men and 380 women) with a mean ± SD age of 41.7 ± 10.2 years were included in the analyses. In total, 152 (27%) participants were from Beijing, 149 (26%) from Wuhan, 110 (19%) from Shenyang, and 157 (28%) from other Chinese cities. Halitosis and bleeding gums were the most common reasons for individuals to seek an intervention. Compared with other cities, participants from Wuhan showed higher anxiety and depression and worse previous oral health. Resilience mediated the relationship between depression and oral health, but not between anxiety and oral health.ConclusionWe hope that the data from this study will inform clinical practitioners and demonstrate that mental health awareness and resilience training are important strategies that may mitigate the negative impact of lockdown and isolation on oral health.     

60Co-γ射线对益母草种子的诱变效应研究

目的 研究γ射线对益母草种子的诱变效应,为采用益母草种子进行诱变育种提供参考依据。方法 以益母草的干燥种子为材料,研究γ射线对其产生的生理效应和诱变效果。以种子发芽率、成苗率、幼苗苗高、根长,以及叶色突变率作为评价诱变效应的指标。结果 γ射线对益母草种子发芽、幼苗生长有明显的抑制作用,具有较强的诱发叶色突变的能力。结论 γ射线对益母草具有诱变作用,益母草干燥种子γ射线诱变育种的适宜辐射剂量范围为400~500 Gy。
