目的探讨螺内酯对心肌肥厚大鼠可溶性ST2(sST2)及核转录因子_κB(NF-_κB)的影响。方法选取健康雄性SD大鼠30只,随机分为对照组(n=10)、模型组(n=10)、药物干预组(n=10)。对照组大鼠皮下注射生理盐水;模型组皮下注射异丙肾上腺素(ISO);药物干预组皮下注射ISO,同时给予螺内酯20mg/(kg·d)灌胃。14d后处死大鼠,计算心脏质量/体质量、左心室质量/体质量,观察心肌细胞直径;免疫组化及逆转录聚合酶链反应(RT-PCR)法检测心肌组织中sST2及NF-_κB的表达;Masson染色观察心肌纤维化程度。结果与对照组比,模型组心脏质量/体质量、左心室质量/体质量、心肌细胞直径升高[(3.39±0.11)比(2.47±0.07)mg/g,(2.34±0.11)比(1.78±0.07)mg/g,(26.30±0.95)比(14.53±0.47)μm;均P<0.05];sST2与NF-_κB mRNA和蛋白表达升高(均P<0.05)。与模型组比较,药物干预组心脏质量/体质量、左心室质量/体质量、心肌细胞直径降低[(2.79±0.07)比(3.39±0.11)mg/g,(1.92±0.10)比(2.34±0.11)mg/g,(20.96±0.65)比(26.30±0.95)μm;均P<0.05],sST2与NF-_κB mRNA和蛋白表达降低(均P<0.05)。心肌纤维化程度:模型组大于对照组,干预组小于模型组。结论螺内酯可能通过调节sST2的表达,抑制下游NF-_κB的表达,对抗ISO诱导的大鼠心肌肥厚。

目的建立饮用水中病毒浓缩与检测方法并对实际水样进行人腺病毒污染状况监测。方法以f2噬菌体为水中肠道病毒代表，投加于受试水样中，评价NanoCeram滤芯对原水和饮用水初次浓缩及不同浓度PEG8000对初次浓缩液进行二次浓缩的效果。采用T以克隆制备人腺病毒荧光定量PCR标准品，对所得质粒测序，应用Blast序列类似性检索工具将其与目的基因片段进行一致性检测，建立荧光定量PCR检测人腺病毒的方法。应用上述方法，于2011年对武汉两家自来水厂原水和饮用水采用NanoCeram滤芯进行现场初次浓缩，聚乙二醇（PEG）／NaCl法进行二次浓缩，提取浓缩液中病毒DNA后进行荧光定量PCR检测，监测原水和饮水中人腺病毒污染状况。结果所建立的NanoCeram滤芯初次浓缩法对原水中的f2噬菌体回收率为（51．63±26．60）％，对饮用水中的￡噬菌体回收率为（50．27±14．35）％。当PEG8000浓度达到0．13kg／L时，二次浓缩回收率可达（90．09±10．50）％。所构建的人腺病毒荧光定量PCR标准品与目的基因片段序列一致度为99％，可用于人腺病毒的绝对定量。2011年，武汉市两家自来水厂原水中的人腺病毒浓度范围为（4．13×103～2．20×103）拷贝／L，出厂水中的人腺病毒浓度范围为（5．57×10。～7．52×105）拷贝／L，饮用水处理过程对人腺病毒的清除率为（75．49±11．71）％。结论NanoCeram滤芯联合PEG／NaCl法可对水环境中病毒进行有效浓缩，应用所建立的荧光定量PCR法检测发现自来水厂原水中存在人腺病毒，目前的水处理措施不能将其完全去除。

新民主主义社会理论成功地指导了新中国建立之初的各项事业建设,可是建国才3年多,新中国就向社会主义过渡,这个理论被放弃,导致了新民主主义社会形态的匆匆中断。关于新民主主义社会中断的原因,理论界有不少探讨,这些原因主要可以分为客观原因和主观原因两大类。客观原因主要有新民主主义理论或实践本身的特点、国家实行工业化战略的需要、国内环境的变化、国际环境的压力;主观原因主要是毛泽东个人认识的变化、对社会主义认识的模糊,人民群众对社会主义的向往。
