A series of three-dimensional opal photonic crystals based on the polymer was synthesized and applied inthe field of photo-induced birefringence. The data show that the photo-induced birefringence（PIB） of pure Sudan IIIfilm could be enhanced by increasing the thickness of azo films. When Sudan III was distributed on thethree-dimensional opal photonic crystals, the photo-induced birefringence process could be modulated. In addition,the data also exhibit that the PIB processes with different pumping polarization directions are sensitive to the role ofphotonic crystals. The results could be beneficial to further understanding the photo-induced birefringence and uti-lizing the photonic crystals.

The relaxation paths for triphenylamine（TPA）-2,3-dicyanopyrazino phenanthrene（DCPP）, which has a pull-push structure, were investigated via steady-state, time-resolved spectroscopy involving transient absorption and time-correlated single photon counting. By changing the solvent polarity we found that an intramolecular charge transfer（ICT） state acting as a ＂bright＂ state was responsible for the fluorescence character of TPA-DCPP. Meanwhile, a ＂dark＂ state gradually appeared and competed with the ICT state. This was likely to be responsible for the polarity-dependent evolution of fluorescence intensity and fluorescence lifetime. The temperature-dependent fluorescence character of the TPA-DCPP in toluene exhibited ICT processes at high temperatures prior to the relaxation path from the initial excited state to the ground state. Our results provide useful insight into the optoelectronic properties of these kinds of molecules.

为了提升天然植物染料栀子黄在纤维素纤维上的染色性能,设计合成了一系列以3-氯-2-羟丙基为反应基团、季铵盐为阳离子基团的阳离子改性剂,通过亲核加成反应在纤维素纤维上引入季铵基团,提升栀子黄染料对阳离子改性纤维素纤维的染色性能。借助电喷雾电离-串联质谱法(ESI-MS)、核磁共振氢谱(~1H NMR)对合成的不同烷基链长的季铵盐改性剂分子结构进行表征。通过红外光谱图和X射线光电子能谱图证实季铵盐化合物以醚键形式成功接枝在棉织物上。采用栀子黄染料对改性棉织物染色,比较不同烷基链长改性剂改性棉织物的染色K/S值发现,改性剂烷基链长为12时最佳,上染率为85.46%,K/S值为4.33。进一步研究染色工艺条件对染色织物K/S值、上染百分率以及色牢度的影响,结果表明,在染色温度为80℃,pH值为9,时间为60 min时,经3-氯-2-羟丙基二甲基辛烷氯化铵(CH-12)改性棉织物染色性能最佳,其上染率为88.07%,K/S值为4.71,耐皂洗牢度及耐摩擦色牢度均可达到3级以上。研究结果表明,CH-12改性棉织物可实现无盐染色,且改性织物的上染率、固色率、耐皂洗和耐摩擦牢度均优于未改性织物的传统有盐染色。

目的:探讨过氧化物酶体增殖物激活受体-γ(PPARγ)激动剂吡格列酮(Pioglitazone)对神经病理性疼痛大鼠痛行为学及对脊髓背角小胶质细胞线粒体氧化应激的影响。方法:将40只SD雄性大鼠按随机数字表法分为4组:假手术(sham)+溶剂二甲基亚砜组(DMSO,S+D组)、sham+Pioglitazone组(S+P组)、坐骨神经结扎(CCI)+溶剂DMSO组(I+D组)和CCI+Pioglitazone组(I+P组)。采用CCI术建立神经病理性疼痛模型,CCI术后第7~14天鞘内注射相应的药物。于术前(T_(0))及术后第3天(T_(1))、第7天(T_(2))、第14天(T_(3))检测各组大鼠机械缩足阈值(PWMT)和热缩足反射潜伏期(PWTL),并取术后第14天大鼠脊髓腰膨大部标本,通过免疫荧光技术观察小胶质细胞活化情况;透射电镜观察小胶质细胞线粒体超微结构的损伤;蛋白免疫印迹(western blotting)检测线粒体生物发生关键调控因子NRF1表达;实时荧光定量PCR技术(RT-qPCR)检测线粒体DNA(mt DNA)含量;氧化物阴离子探针检测活性氧(ROS)水平;检测各组超氧化物歧化酶(SOD)活性以及丙二醛(MDA)水平;酶联免疫吸附法(ELISA)检测炎性因子IL-1β、IL-6、TNF-α的表达。结果:与I+D组相比,I+P组给药后T_(2)~T_(3)时PWMT、PWTL均明显升高(P<0.05),脊髓背角小胶质细胞活化减少(P<0.05),透射电镜显示线粒体结构改善,活性氧ROS和MDA含量降低(P<0.05),SOD酶活性增加(P<0.05),线粒体NRF1和mt DNA的表达增加(P<0.05),同时炎性因子IL-1β、IL-6、TNF-α表达水平降低(均P<0.05)。结论:鞘内注射Pioglitazone可缓解大鼠神经病理性疼痛,其机制可能与抑制小胶质细胞异常活化,保护小胶质细胞线粒体功能,降低氧化应激从而减轻炎症反应有关。
