Research Recommendations on the Effects of Postpartum Depression and Pain on Infant Care and Development

Postpartum depression is one of the most common complications of childbirth, and another is pain. A growing body of research shows that the severity and duration of postpartum pain can increase a woman’s risk for postpartum depression. Postpartum depression and pain negatively affect maternal well-being, and postpartum depression has been associated with adverse outcomes in children. However, there is a dearth of information about the effects of postpartum depression and pain on infant care and development. The objectives of this commentary were to highlight the need to address this gap in the literature, offer a preliminary conceptual model to advance the field, and ignite new lines of inquiry to inform infant care and development.     

Effectiveness of cognitive behavior therapy for patients with heart failure and depression: A systematic review protocol

The objective of this review is to determine the effectiveness of cognitive behavior therapy for patients with heart failure and depression, aged ≥18 years, in institutionalized healthcare settings. More specifically, the review aims to identify which cognitive behavior therapy strategy/strategies, including the method of delivery, is the most effective for the management of depression in hospitalized patients with heart failure. The review question is as follows: Is cognitive behavior therapy effective in reducing symptoms of depression in patients with heart failure? This systematic review will be conducted in accordance with the Joanna Briggs Institute methodology for systematic reviews of effectiveness evidence. This review only includes randomized controlled trials assessing the effectiveness of cognitive behavior therapy as a treatment for depression in adults (aged ≥18 years) with heart failure, compared with usual care, which might include medications.     

循经冥想训练干预大学生抑郁情绪的效果分析

背景　现有研究表明，抑郁是影响大学生心理健康的重要原因之一。因此，有必要采取有效的方法干预大学生抑郁情绪。目的　探究循经冥想训练干预大学生抑郁情绪的效果。方法　2018年4月，在以循经冥想课题组的名义招募的某大学本科生中，发放抑郁自评量表（SDS），筛选出自愿接受循经冥想训练的60人。根据受试者性别比例，采用随机数字表法随机分为循冥组和静息组。其中循冥组30人进行4周循经冥想训练，在开始循经冥想训练前和循经冥想训练结束后填写SDS并进行E-prime情绪图片评价任务。静息组30人进行静息训练，其余与循经冥想组相同。比较两组前测、后测及前后测差值有无差异。结果　两组前测积极、中性、消极情绪图片评分比较，差异均无统计学意义（P>0.05）；两组后测积极、中性、消极情绪图片评分比较，差异均无统计学意义（P>0.05）；两组积极、中性、消极情绪图片评分前测与后测差值比较，差异均无统计学意义（P>0.05）。静息组前测与后测积极、中性、消极情绪图片评分比较，差异均无统计学意义（P>0.05）。循冥组后测积极情绪图片评分低于前测、消极情绪图片评分高于前测（P<0.05）。两组前测SDS评分比较，差异无统计学意义（P>0.05）。循冥组后测SDS评分低于静息组，SDS评分前测与后测差值高于静息组（P<0.05）。循冥组和静息组后测SDS评分均低于前测（P<0.05）。结论　循经冥想能降低大学生抑郁水平，可能是由于其能够改变人的情绪认知评价和睡眠质量，使人变得平和。     

Ketamine in the Treatment of Major Depressive Disorder

Major depressive disorder (MDD) is a prevalent and highly debilitating psychiatric condition that affects many young adults worldwide. This brief review summarizes the current available data about the use of ketamine as a treatment for MDD. We describe pharmacological mechanisms, dose considerations, drug interactions, side effects, and the relevancy of ketamine in the treatment of MDD.     

六味地黄汤干预抑郁大鼠学习记忆的作用机制

目的:探讨六味地黄汤对慢性抑郁大鼠记忆障碍的改善作用,并探讨其可能的作用机制。方法:Wistar雌性大鼠随机分为正常组(生理盐水)、慢性不可预见性温和应激(CUMS)模型组(生理盐水)、六味地黄汤低、中、高剂量组(2. 60,7. 81,23. 50 g·kg~(-1)·d~(-1))。除正常组外,其余各组造成CUMS模型。每周称体质量,观察其行为学指标变化;实时荧光定量聚合酶链式反应(Real-time PCR)检测其海马G蛋白偶联雌激素受体(GPR30),胞内磷脂酰肌醇激酶(PI3K),环磷酸腺苷反应元件结合蛋白(CREB),脑源性神经营养因子(BDNF) mRNA的表达;酶联免疫吸附测定(ELISA)检测血清中雌激素含量。结果:与正常组比较,模型组体质量、活动能力、兴趣等明显降低(P 0. 05,P 0. 01);与模型组比较,六味地黄汤2. 60,7. 81,23. 50 g·kg~(-1)可明显提高CUMS大鼠糖水偏好度(P 0. 01)和旷场实验的站立次数(P 0. 01);7. 81,23. 50 g·kg~(-1)明显提高旷场实验的总距离(P 0. 05,P 0. 01);2. 60,7. 81 g·kg~(-1)可缩短水迷宫实验寻台潜伏期(P 0. 01);7. 81 g·kg~(-1)可增加血清中雌激素含量(P 0. 05);CUMS模型组大鼠海马组织内的GPR30,PI3K,CREB,BDNF mRNA表达明显下降(P 0. 05,P 0. 01),六味地黄汤2. 60 g·kg~(-1)显著增加海马组织内的GPR30,CREB mRNA表达(P 0. 05,P 0. 01),7. 81 g·kg~(-1)明显增加海马组织内的GPR30,PI3K,CREB,BDNF mRNA表达量(P 0. 05,P 0. 01)。结论:六味地黄汤具有抗抑郁作用,逆转CUMS大鼠抑郁样行为及学习记忆障碍,其中中剂量组药效最显著。其作用机制可能与增加血清中雌激素和提高大鼠海马GPR30,PI3K,CREB,BDNF mRNA表达有关。
