Methods Sequence specific primers-polymerase chain reaction was used for the detection of genotypes and alleles of rs3850641 A/G loci in OX40L gene in 187 PACS cases (≤55 years) and 138 controls. Diseased vessel numbers and stenostic severity integral by coronary arteriogram and serum levels of sOX40L, C-reactive protein and vascular cell adhesion molecule-1 (VCAM-1) by enzyme-linked immunosorbent assay and nephelometry were measured. The relationship between OX4OL gene variants and PACS risk, SSI as well as plasma levels of three cytokines were analysed.

采用聚合酶链反应-序列特异性扩增技术检测187例年龄≤55岁、早发急性冠状动脉综合征患者和138例冠状动脉造影正常者rs3850641位点A/G变异的基因型、等位基因及其分布频率;采用冠状动脉造影测量病变血管支数和狭窄程度积分;应用ELISA法测试血浆sOX40L、血管细胞黏附分子(VCAM-1);应用散射比浊法测试血浆C反应蛋白水平;分析OX40L基因变异与ACS风险、冠状动脉病变程度和血浆3个细胞因子之间的关系。

In this study, we isolate, purify and characterize endo-β-glucanase by Ascomycete Xylaria regalis. The cellulose-containing medium is used to induce the production of the cellulose-degrading enzymes. When these enzymes are produced at maximum level, we harvest and filtrate the culture medium. The filtrate is purified by anion exchanger column and hydrophobic interaction column (phenyl-650M). The purification fold of endo-β- glucanase increases 4.3 times, the specific activity approaches 3.7 unit/mg, and the recovery is 27.6%, respectively.

为了分离且纯化此株菌产生在培养基中的endo-β-glucanase,先将此菌在cellulose液态培养基中大量培养,在此酵素达到最高峰时,利用滤纸过滤将菌丝及菌液分开,收集粗酵素液,再经过阴离子交换树脂及疏水性层析管柱(Phenyl-650M)等步骤予以纯化,所得到最终酵素纯度为 4.3倍,比活性为3.7 unit/mg,回收率为27.6%。
