采用二维电泳技术对硝酸银诱导的大豆子叶微粒体膜蛋白进行分离,利用四极杆-飞行时间串联质谱,对仅存在于诱导样品而不存在于对照样品中的蛋白质点进行氨基酸序列测定和分析,以期研究硝酸银处理对大豆子叶微粒体蛋白质的影响。结果显示:硝酸银可以诱导大豆Kunitz胰蛋白酶抑制剂(SKTI)的产生,在诱导处理的子叶中大量存在其成熟形式,也存在其5 kDa小亚基,小亚基含有“GIGTIISSPER”和“FIAEGNPLR”氨基酸序列。该研究结果为SKTI的深入研究提供了实践依据,并为其分离纯化提供了简便途径,从而有利于对其更多性质的进一步研究。

阳痿的临床证型与教科书证型的对比分析

阳痿的临床证型与教科书证型的对比分析

作者： Eric vander wal 南京中医药大学

学位级别：硕士

目的：对于男科疾病阳痿,境外中医内科学教材中的证型,与我们在临床上观察到的证型有较大区别,大部分教材把命门火衰列为第一位,亦无提到各证型的发病比例,而且很多证型没有涉及。笔者于2011至2013年,在徐福松教授指导下,在江苏省中医... 详细信息

目的：对于男科疾病阳痿,境外中医内科学教材中的证型,与我们在临床上观察到的证型有较大区别,大部分教材把命门火衰列为第一位,亦无提到各证型的发病比例,而且很多证型没有涉及。笔者于2011至2013年,在徐福松教授指导下,在江苏省中医院名医堂的男科专家门诊收集40例阳痿病患,并整理数据,分析阳痿主要临床证型,与主要的5本当代中医内科学教材(境外英语版)做对照比较分析,找出区别及发现需要改进之处,继而探讨国际中医教育。方法：教材与临床的两组数据使用两种方法。第一阶段：1.系统的收集及记录5本中医内科学(境外生用)中对于阳痿的分型。辨证分型方法遵循书中辨证方法。2.系统的整理阳痿的40例临床病例数据,在徐福松老师指导下完成。纳入标准：病人主诉无法维持勃起或勃起困难。纳入标准后的病人以中医四诊舌、脉及主诉症状等区分证型。第二阶段：把数据标准化,整理,统计,分析,比较。结果：通过统计后,发现在5本境外中医内科学教材中,共有10种阳痿证型,最常见的教科书证型为肾阳虚(命门火衰),出现率为100%,及肝气郁滞(100%),湿热下注(100%),其次是心脾两虚(80%),惊恐伤肾(60%),心胆气虚(20%),肾阴虚(阴虚火旺)20%,肾精亏虚(20%),寒凝血滞(20%),以及寒滞肝脉占20%。从临床收集的40组病例数据分析来看,总见8种证型,最常见的临床证型是肾阴虚(阴虚火旺),约70%,其次是肝郁气滞,约32.5%,湿热下注患者占27.5%,痰浊阻滞者为12.5%,命门火衰为12.5%,心脾两虚为10%,惊恐伤肾为7.5%,血脉瘀滞者为2.5%。还有许多患者是两种及两种以上的复合证型。40例病患中14例为单一证型,26例为复合证型。平均每个患者患有1.75个证型。在复合证型中统计,阴虚火旺+肝郁气滞组合最多,约占20%,阴虚火旺+湿热下注组合占15%,阴虚火旺+命门火衰组合占7.5%,痰湿阻滞+心脾两虚占7.5%,阴虚火旺+命门火衰+湿热下注组合占5%,湿热下注+惊恐伤肾组合5%,湿热下注+肝气郁滞组合占2.5%,湿热下注+血脉瘀滞组合占2.5%。结论：分析比较了教材与临床的数据,我们发现临床中确有一些证型并没有被大多数教材包含在内,如阴虚火旺,痰湿阻滞,血脉瘀滞,而这三种证型(所占比例分别为70%、12.5%及2.5%)。而临床收集的40例阳痿病患中未见心胆气虚,寒滞肝脉,寒凝血滞,肾精亏虚这几种教科书中提到的证型,可能与样本较小有关,但在另一方而也说明了这几种证型在临床中不太常见。通过分析教科书证型,我们发现肝气郁滞,湿热下注,心脾两虚,惊恐伤肾这几种证型为多数教材的重要证型,特别是命门火衰,是多数中医内科学教材提及的首要证型,但却不是临床的主要证型。值得一提的是,肾阴虚在临床中占主导地位,不管是单一证型还是复合证型。但仅在一本教材中内科学教材中有所涉及。

In this study, MWNT and alumina nanopowder were used as a ruthenium catalyst support for the conversion of carbon monoxide to methane. Metal foam structures were employed to support such catalytic systems, offering interesting possibilities for commercial applications due to low-pressure drop; excellent flow characteristic and heat transfer properties. Prior to the ruthenium impregnation, the MWNT surface was initially modified by means of metal cation activation and surface adsorption of anionic surfactant. The decoration processes using both surface modifications promoted the deposition of ruthenium with a mean 2 nm diameter. The use of nickel as a nucleating center enhanced the Ru nanoparticle density on the CNT surface compared to the Ru/CNT catalyst prepared by excess solution impregnation. As a reducing agent, ethylene glycol completely converted Ru2＋ to Ru0as confirmed by an EDS/TEM analysis. Among the prepared catalysts, Ru/AI203-CNTs prepared by Ni2＋ activation showed the best performance for the hydrogenation reaction. This is interpreted in terms of the higher ruthenium nanoparticle exposure on the nanostructured catalyst, as a result of the better MWNT dispersion in the MWNT/Al2O3 mixture.
