BACKGROUND Mild cognitive impairment(MCI)has a high risk of progression to Alzheimer’s *** disease is often accompanied by sleep disorders,and whether sleep disorders have an effect on brain function in patients with MCI is *** To explore the near-infrared brain function characteristics of MCI with sleep *** A total of 120 patients with MCI(MCI group)and 50 healthy subjects(control group)were *** subjects underwent the functional near-infrared spec-troscopy *** baseline data,Mini-Mental State Examination,Montreal Cognitive Assessment scale,fatigue severity scale(FSS)score,sleep parameter,and oxyhemoglobin(Oxy-Hb)concentration and peak time of functional near-infrared spectroscopy test during the task *** relationship between Oxy-RESULTS Compared with the control group,the FSS score of the MCI group was higher(t=11.310),and the scores of Pittsburgh sleep quality index,sleep time,sleep efficiency,nocturnal sleep disturbance,and daytime dysfunction were higher(Z=-10.518,-10.368,-9.035,-10.661,-10.088).Subjective sleep quality and total sleep time scores were lower(Z=-11.592,-9.924).The sleep efficiency of the MCI group was lower,and the awakening frequency,rem sleep latency period,total sleep time,and oxygen desaturation index were higher(t=5.969,5.829,2.887,3.003,5.937).The Oxy-Hb concentration at T0,T1,and T2 in the MCI group was lower(t=14.940,11.280,5.721),and the peak time was higher(t=18.800,13.350,9.827).In MCI patients,the concentration of Oxy-Hb during T0 was negatively correlated with the scores of Pittsburgh sleep quality index,sleep time,total sleep time,and sleep efficiency(r=-0.611,-0.388,-0.563,-0.356).It was positively correlated with sleep efficiency and total sleep time(r=0.754,0.650),and negatively correlated with oxygen desaturation index(r=-0.561)and FSS score(r=-0.526).All comparisons were P<*** Patients with MCI and sleep disorders have lower near-infrared brain function than norm

OpenAI发布的文字转视频模型Sora在智能影像生成领域取得突破,被认为具备“世界模拟”能力。这种对现实物理世界的逼真模拟能力,引发人类对“真实性”的重新评估。通过模拟现实场景和历史事件,Sora在展示其应用潜力的同时,对真实性、历史真相和公众信任等带来挑战。文本介绍了Sora的技术背景,探讨了智能影像与虚假信息结合的风险。这一结合可能通过社会媒介影响公众信念和政治秩序,引发社会极化和分化。此外,在重塑历史记忆与认同时,可能导致信息的扭曲和伪造问题,或将社会推向政治非稳态。为应对技术带来的挑战,文本强调在迈向通用人工智能时代的过程中平衡技术创新与社会责任的重要性。通过深入分析Sora等智能影像生成的可能影响与挑战,提醒社会关注生成式人工智能技术的监管和伦理,确保技术发展的同时维护历史的真实性,保障社会福祉。

[目的]开展土壤生态化学计量特征随植被恢复进程的变化研究，探究植被恢复引起土壤养分变化规律及其作用机制，对认识植被恢复与土壤养分的关系，指导植被恢复实践具有重要意义。[方法]以晋西黄土区不同植被恢复阶段(撂荒地、草地、灌木林、先锋阔叶林、针叶林)的5种林(草)地为研究对象，通过调查采样和室内分析，探究土壤生态化学计量特征随植被恢复的进程变化及其影响因素。[结果](1)随着植被的恢复，先锋阔叶林和针叶林阶段的SOC含量较上一阶段增加19.8%,土壤TN含量较上一阶段增加17.6%,而土壤TP含量较上一阶段减少12.4%;(2)随着植被恢复的发展，土壤C∶P和N∶P显著增加，C∶N的变化无明显规律，在先锋阔叶林和针叶林阶段的土壤C∶P较上一阶段增加26.6%;先锋阔叶林和针叶林阶段在0—40 cm土层的土壤N∶P较上一阶段增加40.2%,40—100 cm土层的土壤N∶P较上一阶段增加35.7%;土壤C∶N在不同植被恢复阶段间的变化未见明显规律，研究区土壤逐渐由C,N的限制转变为P的限制；(3)各植被恢复阶段土壤C∶P和N∶P主要与砂粒含量呈显著负相关，与孔隙度呈显著正相关，土壤C∶N与其他因子的相关性不明显。[结论]植被恢复有利于土壤C,N含量增加，改善土壤理化性质，在植被恢复过程应同时注重P元素的调控，以提高晋西黄土区植被生态恢复水平。

背景:横截面积和脂肪浸润为量化椎旁肌的标准参数,但是太过繁琐和费时,需要引入新的量化指标。目的:探讨峡部裂性腰椎滑脱患者椎旁肌和脊柱-骨盆矢状面参数测量值之间的关系,以及腰椎压痕值对矢状面平衡的预测价值。方法:选择诊断为峡部裂性腰椎滑脱的患者87例,均为Meyerding分型Ⅱ度滑脱,男40例,女47例,平均年龄(51.4±9.1)岁。测量患者脊柱-骨盆矢状面参数矢状面轴向距离、骨盆入射角、骨盆倾斜角、骶骨倾斜角、腰椎前凸角、胸椎后凸角、骨盆投射角与腰椎前凸角之差,以及腰椎旁肌的总横截面积、功能横截面积和脂肪浸润。使用Pearson相关分析法探讨矢状面参数与椎旁肌测量值的相关性;使用多元线性回归分析腰椎压痕值、年龄、性别和体质量指数对脊柱骨盆矢状面平衡的影响。通过受试者工作特征曲线寻找腰椎压痕值的最佳截断点,评价矢状面轴向距离和骨盆投射角与腰椎前凸角之差的关系。结果与结论:(1)根据Pearson相关分析结果,多裂肌总横截面积与腰椎前凸角(r=0.464,P 11.5 mm的患者矢状面轴向距离≤50 mm发生率为96%(64/67);骨盆投射角与腰椎前凸角之差≤11.5 mm的患者骨盆投射角与腰椎前凸角之差≤10°的发生率为30%(6/20),而腰椎压痕值> 11.5 mm的患者骨盆投射角与腰椎前凸角之差≤10°的发生率为66%(44/67);(3)提示多裂肌总横截面积和功能横截面积均与腰椎前凸角和骨盆投射角与腰椎前凸角之差显著相关;腰椎压痕值作为评价椎旁肌退变的新指标,与矢状面轴向距离和骨盆投射角与腰椎前凸角之差独立相关,对术后矢状面矫正有一定的预测价值,是一种简单实用的评估脊柱-骨盆矢状面和椎旁肌退变的方法;椎旁肌的退变与脊柱-骨盆矢状面平衡有关。
