本文采用分子动力学模拟方法研究离子的存在对水蒸气核化过程的影响。模拟系综初始温度为600 K,达到平衡后撤去水蒸气热浴,将载气温度标定至200 K,与水蒸气进行热量交换,带走水蒸气核化释放的核化潜热。研究结果表明,离子的存在能够促使核化的发生,但离子的浓度对系综内最大团簇的生长影响较小。根据团簇分析统计系综内含20个Na^+/Cl^-时,核化率约为1.01×10^(28)cm^(-3)·s^(-1),与经典核化理论计算值4.89×10^(28)cm^(-3)·s^(-1)在同一个数量级。

根据户外照明系统自清洁功能的需求,基于光学薄膜理论,对复合膜折射率和质量配比进行了理论分析与模拟,采用电子束共蒸发技术镀制TiO_2/Al_2O_3复合膜,并对其做真空退火处理.在单晶控系统中,通过控制左右两电子枪的束流,镀制了不同质量配比复合膜.亲水性测试和甲基橙实验表明,复合膜中TiO_2的质量配比越高,自清洁效果越好,但亲水性和可见光透过率会降低.对不同质量配比的复合膜进行了检测和分析,并通过调整质量配比来优化试验方案,结果表明,TiO_2/Al_2O_3质量配比为9:1时,该薄膜既具有自清洁亲水作用,又具较高的可见光透过率.

我国正步入老龄化社会,社会交往活动对实现健康老龄化具有积极作用,深入理解社区建成环境对老年人社会交往活动的影响,是促进老年人身心健康的重要途径。本文基于2015年"第四次中国城乡老年人生活状况抽样调查"数据,运用多水平回归模型,重点考察社区建成环境对老年人社会交往活动的影响。研究发现,我国老年人36%的社会交往水平差异由老年人所处社区决定;社区层面,距离中心城区较近,社区周边1km范围内拥有老年人活动中心、露天健身器材场地、图书馆/文化站、宗教设施,以及道路质量较好的社区,往往居住于其中的老年人社会交往活动水平较高;个体层面,年龄、性别、婚姻状态、受教育程度、家庭年收入等因素亦与老年人社会交往活动水平密切相关。

目的观察呼吸机相关性肺炎（ventilator associated pneumonia,VAP）患者外周血和支气管肺泡灌洗液（bronchoalveolar lavage fluid,BALF）中CD4＋CD25＋CD127dim/-调节性T细胞（regulato-ry T cells,Tregs）和白细胞介素（interleukin,IL）-35的变化,并分析IL-35对Tregs的调控在VAP发病中的作用.方法收集23例VAP患者和11例健康志愿者（normal controls,NCs）,分离外周血单个核细胞、血清和BALF,通过酶联免疫吸附试验检测IL-35水平,通过流式细胞术检测CD4＋CD25＋CD127dim/-Tregs比例.纯化BALF中CD4＋CD25＋CD127dim/-Tregs,利用重组人IL-35对纯化的Tregs刺激培养后与自体CD4＋CD25-T细胞共培养,检测细胞增殖和分泌细胞因子水平.结果外周血中Tregs的比例和血清IL-35水平在VAP患者和NCs之间差异无统计学意义.但在VAP患者中,感染部位BALF中Tregs的比例和IL-35水平较非感染部位显著升高,且BALF中Tregs的比例与IL-35水平呈显著正相关（r=0.441,P=0.035）.经抗感染等综合治疗后,病情好转的患者BALF中Tregs的比例和IL-35水平较治疗前显著下降,Tregs分泌IL-35的水平亦显著下降,但病情未好转或恶化的患者BALF中Tregs的比例和IL-35水平与治疗前比较则无明显变化,Tregs分泌IL-35的水平亦无明显变化.同时,病情好转患者Tregs抑制细胞增殖能力和分泌IL-10水平均较病情未好转或恶化患者减弱.利用重组人IL-35刺激治疗前患者BALF中纯化的Tregs可增强其免疫抑制功能,主要表现为细胞增殖减弱、抑制性细胞因子（IL-35和IL-10）分泌增多以及促炎因子（IFN-γ和TNF-α）分泌减少,但是,IL-35对治疗好转患者BALF中纯化Tregs的功能无显著影响.结论 IL-35和Tregs在VAP患者BALF中显著升高,且IL-35可增强Tregs的免疫抑制功能.IL-35调控Tregs功能可能参与了VAP的发病.
