Efficient tumor-targeting drug delivery systems are urgently needed for treating metastatic breast *** this work, a docetaxel(DTX)-loaded micelle(pDM) as the tumor-microenvironment-responsive delivery platform is developed. The micelle is composed of a pH-sensitive amphiphilic copolymer,poly((1,4-butanediol)-diacrylate-b-N,N-diisopropylethylenediamine)-polyethyleneimine(BD-PEI), and a matrix metalloproteinase(MMP)-responsive polymer, poly((1,4-butanediol)-diacrylate-b-N,N-diisopropy lethylenediamine)-peptide-polyethylene glycol(PEG)(BD-peptide-PEG). The PEG block of BD-peptidePEG will be split by MMPs at the tumor microenvironment, which leads to the change of the surface charge and particle size of the micelle to more positive and smaller one. Owing to this transformation and enhanced permeability and retention(EPR) effect, pDM delivers more DTX into tumor tissues and is internalized more efficiently by tumor cells than the non-MMP-sensitive micelles in the 4 T1 tumorbearing mice model. In addition, DTX is released in acidic endo/lysosomes due to the dissociation of the micelle, triggered by the protonation of the hydrophobic block of BD-PEI. As a result, the DTX-loaded micelle inhibits primary tumor growth and pulmonary metastasis effectively. Thus, this pH/MMP-dual-sensitive drug delivery system, which simultaneously attains three keypoints: prolonged circulation time, directional and efficient uptake into tumor cells, and speedy intracellular drug release, is a promising strategy for metastatic breast cancer therapy.

当前,碳市场(carbon emissions trading,CET)作为一种创新的碳减排机制,已在我国成为一种减缓碳排放增长的关键策略。然而我国在关于碳市场的政策体系方面仍有待完善,特别在政策的松紧程度对经济和环境的影响上还缺乏有效的论证。基于此,构建一个基于多主体模拟的碳市场交易模型,从电力企业、政府、用户3类主体的行为入手,自底向上地分析不同碳市场政策情景对企业经济效益和碳排放的影响,旨在为我国出台合适的碳市场政策提供参考。研究结果表明:政府应适当放开对碳价的限制以激发电力企业技术更新的意愿;政府在出台碳超排惩罚政策、碳配额分配政策以及技术更新补贴政策时,应做好经济与环境间的平衡,既确保政策能有效推动减排,又保证企业经济效益;电力企业应积极引入更先进的碳减排技术,承担社会责任,以助力实现碳中和。

为探讨家庭功能影响青少年消极冒险行为的作用机制及条件,采用青少年冒险行为问卷、家庭功能问卷、自尊问卷、同伴群体特征问卷对山东省日照市940名初高中学生进行调查。结果发现:(1)家庭功能不良不仅可直接预测青少年更多的消极冒险行为,而且也可通过使青少年交往更多不良同伴进而使其冒险行为进一步增多;(2)不良同伴交往对青少年消极冒险行为的预测受到个体自尊的调节。低自尊个体更容易受到不良同伴交往的影响而发生更多的消极冒险行为,表现出两风险因素的叠加效应。研究结果提示,家庭是青少年健康成长的基础,家庭功能不良可使青少年适应不良,塑造良好的同伴环境、培养良好的自我素质或可降低这一风险。

为探讨不同社交网站使用(微信和微博)和大学生抑郁的关系以及上行社会比较和妒忌在其中的链式中介作用,采用问卷法对481名大学生进行施测。结果发现:(1)微信对大学生抑郁的总效应不显著,而微博对大学生抑郁的总效应显著,即微博使用越多,抑郁越多;(2)微信使用既可以直接负向预测抑郁,也可以通过上行社会比较和妒忌的链式中介作用间接地正向预测抑郁;而微博使用不能直接预测抑郁,其效应完全由上行社会比较和妒忌所链式中介。研究提示,微信使用和微博使用与大学生抑郁的关系及其机制是不同的,微信比微博有更复杂的作用机制和多种效应。
