Efficient local gene transfection on a tissue scaffold is dependent on good cell-adhesion characteristics. In this work, the thermoresponsive gelatin-functionalized polycaprolactone(PCL) films were proposed for improvement of cell adhesion and intelligent recovery of gene-transfected cells. Functional copolymer brushes(PCL-g-P(NIPAAm-co-MAAS)) were first prepared via surface-initiated ATRP of N-isopropylacrylamide(NIPAAm) and methacrylic acid sodium salt(MAAS) from the initiatorfuncationalized PCL surfaces. The pendant carboxyl end-groups of the PCL-g-P(NIPAAm-co-MAAS) surface were subsequently coupled with gelatin via carbodiimide chemistry to produce the thermo-responsive gelatin-functionalized PCL surface. The thermo-responsive gelatin-functionalized PCL film surface can improve cell adhesion and proliferation above the LCST of P(NIPAAm) without destroying cell detachment properties at lower temperatures. The dense transfected cells can be recovered simply by lowering culture temperature. The thermo-responsive gelatin-functionalized PCL films are potentially useful as intelligent adhesion modifiers for directing cellular functions within tissue scaffolds.

氮素是植物生长发育所必需的主要营养元素,硝酸盐是植物吸收氮的主要形式。盐胁迫是一类非生物胁迫,抑制植物的生长发育。为了探讨盐胁迫影响硝酸盐吸收与植物生长发育的关系,本研究以耐盐模式植物盐芥为试验材料,测定了盐胁迫下盐芥体内硝酸盐含量的变化,分析其与根系发育的关系,并利用RNA-seq技术分析了盐胁迫条件下盐芥中硝酸根转运蛋白(nitrate transporter,NRT)基因的表达调控。结果显示,盐胁迫后盐芥叶片和根中的硝酸盐含量均显著下降,且根系干重与硝酸盐含量呈正相关关系,表明盐胁迫抑制了盐芥对硝酸盐的吸收,并且影响根系的发育。RNA-seq共检测到10个盐芥硝酸根转运蛋白基因的表达,大部分基因的表达受盐胁迫的调控,可能参与了盐胁迫条件下盐芥体内硝酸盐的吸收和转运。综合上述结果,推测盐胁迫抑制盐芥对硝酸盐的吸收,可能是导致盐胁迫下植物生长发育受抑制的因素之一。

目的探讨无创心脏冠脉成像(computed tomography angiography,CTA)在诊断儿童川崎病(KawaskiDisease,KD)急性期冠状动脉病变(coronary artery lesion,CAL)的临床应用价值。方法选择2010年9月至2012年9月潍坊医学院附属潍坊市人民医院儿内科收治的KD患儿35例,男22例,女13例,发病年龄6个月～8岁,平均(2.0±1.6)岁,均采用实时三维超声心动图(Real-Time Three-Dimensional Echocardiography,RT3DE)及心脏CTA检查,观察冠状动脉(冠脉)各支的走向、形态,测量其内径,并对两种检查所得数据进行对比分析。结果心脏CTA显示CAL 14例,累及冠脉15支,其中左冠脉瘤1支、粗细不均4支、扩张7支;右冠脉瘤1支、扩张2支。RT3DE显示CAL 8例,累及冠脉9支,其中左冠脉瘤1支,扩张6支;右冠脉瘤1支,扩张1支。两种检查方法探察冠脉扩张的阳性率差异无显著性(P>0.05);探察冠脉粗细不均有显著性差异(P<0.05)。两种方法显示左右冠脉内径有良好的相关性,相关系数分别为r=0.95,r=0.90(P均<0.01)。结论 RT3DE对CAL的显示不及CTA。CTA能早期发现冠脉任何部位的病变,较准确的评价KD急性期冠脉病变,对KD急性期冠脉炎的早期诊断具有重要的临床意义。

Traditional microstructure scale parameters have difficulty describing the structure and distribution of a roughmaterial’s surface morphology comprehensively and quantitatively. This study constructs hydrophilic and underwateroleophobic surfaces based on polyvinylidene fluoride (PVDF) using a chemical modification method, and the fractaldimension and multifractal spectrum are used to quantitatively characterize the microscopic morphology. A new contactangle prediction model for underwater oleophobic surfaces is established. The results show that the fractal dimension ofthe PVDF surface first increases and then decreases with the reaction time. The uniformity characterized by the multifractalspectrum was generally consistent with scanning electron microscope observations. The contact angle of water droplets onthe PVDF surface is negatively correlated with the fractal dimension, and oil droplets in water are positively *** the fractal dimension is 2.0975, the new contact angle prediction model has higher prediction accuracy. Themaximum and minimum relative deviations of the contact angle between the theoretical and measured data are 18.20%and 0.72%, respectively. For water ring transportation, the larger the fractal dimension and spectral width of the materialsurface, the smaller the absolute value of the spectral difference, the stronger the hydrophilic and oleophobic properties, andthe better the water ring transportation stability.

The open circuit voltage （Voc） of small- molecule organic solar cells （OSCs） could be improved by doping suitable fluorescent dyes into the donor layers. In this paper, 4-（dicyanomethylene）-2-t-butyl-6-（1,1,7,7- tetramethyljulolidyl-9-enyl）-4H-pyran （DCJTB） was used as a dopant, and the performance of the OSCs with different DCJTB concentration in copper phthalocyanine （CuPc） was studied. The results showed that the Voc of the OSC with 50% of DCJTB in CuPc increased by 15%, compared with that of the standard CuPc/fullerene （C60） device. The enhancement of the Voc was attributed to the lower highest occupied molecular orbital （HOMO） level in the DCJTB than that in the CuPc. Also, the light absorption intensity is enhanced between 400 and 550nm, where CuPc and C6o have low absorbance, leading to a broad absorption spectrum.
