To evaluate the LDL particle size and subfraction pattern and their association with coronary heart disease in Chinese population, a case-control study was conducted. Using the agarose-acrylamide composite gradient gel electrophoresis, LDL peak particle diameter was determined in 105 subjects with angiographically verified coronary artery disease and 103 matched healthy controls. Two LDL subfraction patterns were identified by the LDL peak particle diameter.

本课题以病例对照研究设计评估国人LDL颗粒大小和亚组分模式及其与冠心病关系。105例经冠状动脉造影确诊的冠心病患者和年龄性别构成匹配作为对照组的103例健康检查者的LDL峰颗粒直径，用琼脂糖聚丙烯酰胺混合凝胶电泳进行测定。

Here, by introducing C-terminally 6xHis-tagged human Nap1 gene into Escherichia coli and exploiting the nickel-charged sepharose gel system to purify the human Nap1 protein, we show that the Nap1 enzyme function is preserved in human as in lower organisms such as bacteria and plants using succinamic acid as the substrate.

此研究中，我们将已在胺基末端接上6个组胺酸标记的Nap1基因表现在大肠杆菌中，并使用接合上镍原子的琼脂糖凝胶纯化出人类Nap1蛋白，再以丁醯胺酸作为受质，证明人类Nap1蛋白具有酵素活性。

Methods: The specimens of peripheral blood were collected from 15 individuals and each specimen was divided into three parts, one processed in an hour and the other two stored at -80℃ and -20℃ respectively Two different reagents (TRI Reagent and TRI Rcagent-BD) were used to extract RNA directly from whole blood followed by reverse-transcription polymerase chain reaction for amplifying 3-Actins gene. The RT-PCR products were detected by the ultraviolet transilluminator after 1.5% agarose gels electrophoresis and being stained by ethidium bromide.

采集人体外周血标本15例，分成三份，分别作为新鲜血组、-80℃冻存血组和-20℃冻存血组标本，用TRI Reagent和TRI Reagent-BD两种不同的试剂提取RNA，以RT-PCR方法扩增β-Actin基因，经1.5%琼脂糖凝胶电泳，溴化乙锭染色，紫外透射仪下观察分析。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.
