用甲基丙烯酸缩水甘油酯(GMA)对海藻酸钠(Na-Alg)进行接枝改性得到了产物Alg-GMA,利用光引发自由基聚合协同二价阳离子(M^(2+),M代表Ca和Ba)配位交联作用,可调节海藻酸盐水凝胶(M-Alg-GMA)的结构与性能。采用FTIR、1HNMR、XPS、ICP和SEM对其进行了表征,并对其力学性能、溶胀性能、降解性能、体外释放、血液相容性及细胞毒性进行了测试。结果表明,Alg-GMA中出现了与GMA相关的氢信号。在光引发剂Irgacure 2959存在下,Alg-GMA经波长365 nm紫外光照射90 s即可快速形成Na-Alg-GMA水凝胶。Ca^(2+)和Ba^(2+)具有调节海藻酸盐水凝胶结构与性能的作用,这可能与Ca^(2+)的平面四方形构型dsp2轨道杂化方式和Ba^(2+)的正八面体构型d2sp3轨道杂化方式有关。Ca-Alg-GMA和Ba-Alg-GMA均具有肠道靶向释放药物能力,且均具有血液相容性好、细胞毒性低的特点。

利用肿瘤细胞内的高水平还原型谷胱甘肽(GSH)环境特征,该文将抗肿瘤药物姜黄素(CUR)通过二硫键连接到亲水性透明质酸(HA)和聚乙二醇(PEG)分子上,构建了对GSH具有还原敏感刺激响应的CUR-SS-PEG-HA前药纳米胶束。FT-IR和1H-NMR分析结果证明疏水性CUR分子被成功键合在亲水聚合物骨架上。CUR-SS-PEG-HA前药胶束的临界胶束浓度(CMC)为0.098 mg/mL,载药量达到19.74%(w/w);动态光散射法测得胶束平均水合粒径为438 nm,Zeta电位为-23.5 mV;透射电镜观测到尺寸均一且单分散性良好的球形纳米胶束。模拟肿瘤细胞内高浓度GSH环境,在10 mmol/L GSH溶液中观测到前药胶束尺寸显著增大和溶液荧光强度显著增强,CUR从胶束中释放的速率比不含GSH的对照样品快7倍左右。因此,还原敏感聚合物前药胶束可以为设计肿瘤治疗新方案提供有益借鉴。

鄂西宜昌地区夷陵区块五峰—龙马溪组获重大页岩气发现。以研究区夷地1井为研究对象,根据总有机碳(TOC)质量分数、主微量元素、扫描电镜等测试,分析五峰—龙马溪组页岩沉积环境特征及其页岩气地质意义。结果表明:五峰组和龙马溪组下段TOC质量分数平均大于2.00%,为富有机质页岩,相对富集Si、Ca、Vr、Co、Ni、Zn、Mo、Ba和U。五峰—龙马溪组属于强滞留环境,五峰组和龙马溪组下段主要沉积于底水缺氧铁化环境,古生产力较高,是有机质富集的主要原因。鲁丹阶向埃隆阶过渡期,广西运动导致的构造剧烈抬升,底水氧化,洋流上涌较弱,导致水体贫营养化,是笔石带由LM5转变为LM6的主要原因。富有机质页岩特别是龙马溪组下段储层物性较好,含气量高。与川东南礁石坝区块相比,五峰—龙马溪组富有机质页岩厚度较薄(10~20 m),总含气量较低,TOC质量分数较高,且受黄陵刚性基底保护构造改造弱,在研究区北东靠近秦岭洋方向,具备较好的页岩气勘探潜力。该结果对鄂西宜昌地区页岩气勘探开发具有指导意义。
