目的:考察大学生正念与焦虑之间的关系,并检验负面评价恐惧与反刍思维在其中的链式中介作用。方法:采用正念注意觉知量表(MAAS)、反刍思维量表(RRS)、广泛性焦虑障碍量表(GAD-7)和负面评价恐惧量表简版(BFNES)对山东省高校1409名本科生进行问卷调查。结果:①正念可以显著负向预测大学生的焦虑水平(β=-0.519,P<0.001);②负面评价恐惧(β=0.074,P<0.001)与反刍思维(β=0.554,P<0.001)分别在正念对焦虑的影响中起部分中介作用,占总效应的比值分别为9.28%和67.89%;③正念还可以通过负面评价恐惧和反刍思维组成的链式中介(β=-0.066,P<0.001)间接影响大学生的焦虑水平,效应占比为22.83%。结论:正念对大学生焦虑水平具有显著的负向预测作用,既包括直接效应,也包括负面评价恐惧和反刍思维的间接效应。负面评价恐惧和反刍思维在正念与焦虑之间起部分中介作用,并通过链式中介效应进一步解释了正念如何影响焦虑。

Toll-like receptors (TLRs) play critical roles in innate immunity and inflammation. The molecular mechanisms by which TLR signaling is fine-tuned remain to be completely elucidated. Cullin 4B (CUL4B), which assembles the CUL4B-RING E3 ligase complex (CRL4B), has been shown to regulate diverse developmental and physiological processes by catalyzing monoubiquitination for histone modification or polyubiquitination for proteasomal degradation. Here, we identified the role of CUL4B as an intrinsic negative regulator of the TLR-triggered inflammatory response. Deletion of CUL4B in macrophages increased the production of proinflammatory cytokines and decreased anti-inflammatory cytokine IL-10 production in response to pathogens that activate TLR3, TLR4, or TLR2. Myeloid cell-specific Cul4b knockout mice were more susceptible to septic shock when challenged with lipopolysaccharide, polyinosinic-polycytidylic acid or Salmonella typhimurium infection. We further demonstrated that enhanced TLR-induced inflammatory responses in the absence of CUL4B were mediated by increased GSK3β activity. Suppression of GSK3β activity efficiently blocked the TLR-triggered increase in proinflammatory cytokine production and attenuated TLR-triggered death in Cul4b mutant mice. Mechanistically, CUL4B was found to negatively regulate TLR-triggered signaling by epigenetically repressing the transcription of Pten, thus maintaining the anti-inflammatory PI3K-AKT-GSK3β pathway. The upregulation of PTEN caused by CUL4B deletion led to uncontrolled GSK3β activity and excessive inflammatory immune responses. Thus, our findings indicate that CUL4B functions to restrict TLR-triggered inflammatory responses through regulating the AKT-GSK3β pathway.

目的:研究配置不同植物对半寄生植物蒜头果(Malania oleifera)生长的影响,筛选优良的寄主植物,为其引种驯化提供依据。方法:开展不同植物与蒜头果盆栽共培养试验,试验18个月后,对蒜头果的株高、地径、生物量、吸器的数量和大小、叶绿素含量及根、茎、叶中营养元素含量进行测定分析。结果:配置不同寄主植物的蒜头果生长有显著差异。旱冬瓜(Alnus nepalensis)作为寄主植物的蒜头果表现最好,株高、地径和地上部分生物量分别达到72.92 cm、9.83 mm和33.57 g,是不配置寄主植物(对照)的1.89倍、1.45倍和3.19倍;其次是配置假蒿(Eupatorium capillifolium)的蒜头果,株高、地径和地上部分生物量分别为57.55 cm、8.66 mm和22.49 g,是对照的1.49倍、1.28倍和2.14倍。蒜头果植株的叶绿素含量和不同部位全氮、全磷、全钾含量也是配置旱冬瓜和假蒿的处理显著高于其他处理。结论:适宜的寄主植物能提高蒜头果对养分的吸收能力,增强叶绿素的合成,从而促进蒜头果的生长发育,无寄主配置的蒜头果生长不良,蒜头果对寄主植物表现出较强的依赖性。旱冬瓜和假蒿可作为优良的寄主植物在蒜头果人工种植中推广应用。
