With more and more lithium-ion batteries(LIBs) being put into production and application, precious metals such as lithium and cobalt are scarce, so it is imminent to recover various strategic metal resources from spent ***, the complex and difficult problem of separating and recovering metals from leaching solutions has been an urgent question that needs to be resolved. In this work, a phosphoric acid-based deep eutectic solvent(DES) was developed for extracting metals from spent LIBs and one-step selectively separating and efficiently recovering transition metal. The prepared DES shows excellent extraction performance for Li(100%) and Co(92.8%) at 100°C. In addition, the extraction system can effectively separate and precipitate Co through its own components, avoiding the introduction of new precipitants and the destruction of the original composition structure of DES. This also contributes to the good cycle stability of the extraction system with excellent extraction performance for Li(94.3%) and Co(80.8%) after 5 cycles. This work proposes a green method for one-step selectively separating and recovering valuable metals from spent LIBs.

在空泡动力学研究中，阻尼机制对气泡泡壁运动具有非常重要的影响。空泡动力学中所涉及的阻尼机制一般分为3种：黏性阻尼、热阻尼、声阻尼。本文基于泡壁运动方程，通过理论分析和推导，从主导阻尼机制的角度对气泡半径进行了分区讨论，获得了简化的阻尼比公式，证明了空泡动力学中过阻尼系统的存在性。与亚阻尼系统相比，过阻尼系统中的气泡并非进行衰减的往复简谐振荡，而是从初始位置逐步衰减至平衡位置。

OBJECTIVE: To summarize the evidence from Traditional Chinese Medicine(TCM) practice in the treatment of acute primary headache and provide clinical practice guidance. METHODS: The guidelines were developed in accordance with the World Health Organization guideline development manual. After the establishment of steering committee, panel and the registration and protocol formulation, the evidence on TCM for acute primary headache from published guidelines, clinical evidence, and expert experience and consensus were collected. The grading of recommendations assessment, development and evaluation method was used to grade the evidence and make the recommendations. RESULTS: Based on the available evidence, the guidelines recommended three TCM herbal decoctions, six Chinese patent medicines, and two kinds of external application of Chinese herbal medicines. Diagnostic recommendations based on the expert experience and consensus were also included in the guidelines. CONCLUSION: TCM diagnosis and treatment of decoction, Chinese patent medicine and external application for treating acute primary headache were recommended. We hope these guidelines will be helpful in standardize the TCM acute treatment of primary headache.

目的探讨跑步对慢性不可预知性(chronic unpredictable stress, CUS)抑郁症模型小鼠抑郁样行为的影响和内侧前额叶皮质(medial prefrontal cortex, mPFC)内GABA能中间神经元、PV+中间神经元和GAD67+/PV+细胞比例的影响。方法选取4~6周龄的雄性C57BL/6小鼠,CUS建模成功后,利用糖水偏好实验结果将其以分层随机法分为对照组、CUS模型对照组和CUS模型+跑步组。运用糖水偏好实验、强迫游泳实验和悬尾实验评估各组小鼠的行为学水平。采用qRT-PCR检测小鼠mPFC中GAD1、GAD2、PV和CCK的mRNA表达水平。采用免疫组织化学和现代体视学相结合的方法对小鼠mPFC内GABA能中间神经元和PV+中间神经元数量进行精确三维定量,并分析PV+/GAD67+细胞比例。结果与CUS模型对照组小鼠相比,CUS模型+跑步组小鼠和对照组的糖水偏好百分比显著增加(P 0.05);CUS模型对照组小鼠mPFC中PV的mRNA表达水平、PV+中间神经元数量和PV+/GAD67+细胞比例均显著低于CUS模型+跑步组和对照组(P<0.05)。结论跑步可能通过调节PV+中间神经元的数量和基因表达从而发挥抗抑郁效应。

对多阶段属性事件的预测问题而言,精准地提取阶段转化规律对有效预测未来发展趋势起着至关重要的作用。提出了一种基于XGBoost的状态转移预测模型分析阶段间的转化规律并预测事物状态的未来发展趋势。首先,对数据库样本集的原始数据进行预处理,构建XGBoost算法预测样本状态的转化规律,并采用最小二乘法估算阶段间的状态转移概率矩阵;然后,基于得到的转移概率矩阵对个体状态的发展趋势进行预测;最后,以某高校学生在校期间的学习数据为例验证所提出模型的可行性及有效性。十折交叉检验结果显示:笔者算法二分类状态判别准确率可以达到85.402%,平均精准率可以达到84.035%,曲线面积(Area under curve, AUC)值为0.875 74;四分类状态判别准确率可以达到86.084%,平均精准率可以达到75.993%,AUC值为0.764 78。相较于其他几种经典的机器学习分类预测器(KNN,SVM等),XGBoost算法得到的预测结果精度更高且更加稳定。

长期护理保险是人口老龄化背景下健全多层次社会保障体系、在发展中保障和改善民生的重要战略举措。然而,在试点推广的进程中,精算平衡与制度公平之间存在矛盾关系。厘清财政负担的概念、现状和未来趋势,对于协同促进长期照护服务体系建设具有重要作用。本文基于对试点方案的分类梳理,通过计算分年龄、分性别失能率和中/重度失能老年人口规模,测算得出2024~2050年试点方案推广情形下城镇职工与城乡居民长护险的需求成本规模,从而预估其财政补贴状况与兜底负担。研究发现,2050年低、中、高方案下财政负担总额预计分别为168.9亿元、2832.0亿元、7016.4亿元,占当年政府卫生支出的比例为0.23%、3.90%、9.66%。现行筹资机制能够基本保证低方案和中方案中城镇职工部分的财政负担稳定在合理范围内,中方案中城乡居民部分则需要大量财政补贴,整体不可持续,高方案基本不具备财务可持续性。
