目的 建立生物检材中五氯酚的高效液相色谱检测方法。方法 将鱼内脏组织匀浆,用有机溶剂萃取后,采用高效液相色谱仪检测。对高效液相色谱条件进行反复筛选,同时以空白添加实验考察回收率、线眭范围、检测限。结果建立了以乙醚为提取溶剂处理样品,采用Hypersil ODs柱(4.6mmi, d×150mm,5um),甲醇:2g/L醋酸铵水溶液(80:20)为流动相的高效液相色谱分析方法。305nm进行检测,同时收集全光谱信息。按上述方法分析生物检材中的五氯酚,方法平均回收率为76%,检测线眭范围为0.042ug/g~1.344ug/g,相关眭良好r=0.9994),检测限为0.014ug/g。运用该方法成功地从中毒鱼体中检出五氯酚。结论所建立方法能便捷、准确地检测生物检材中五氯酚,为法医学中毒鉴定提供了新方法。

Coronary atherosclerotic heart disease (CAD) is a multifactorial disorder resulting from numerous gene–gene and gene–environment interactions. Lecithin:cholesterol acyltransferase (LCAT), a key enzyme in reverse cholesterol transport and the metabolism of high-density lipoprotein (HDL), is thought to be a candidate gene related to dyslipidemia and CAD. Variations in the LCAT gene were investigated in 190 CAD patients and 209 age-and gender-matched controls by denaturing high-performance liquid chromatography, and confirmed by sequencing and RFLP assay. In CAD patients, a novel single-nucleotide polymorphism (P143L) in exon 4 of the LCAT gene was discovered in nine males and two females (frequency of 5.79%), which was found in none of 209 controls. The genotype and allele distribution of P143L is significantly (P<0:04) higher in the low HDL-C subgroup than in the normal HDL-C subgroup in both male patients and all CAD patients. P143L was also found to be significantly (P < 0:01) associated with the low HDL-C phenotype in both male patients and all CAD patients, with odds-ratios of 7.003 (95% CI 2.243–21.859) and 5.754 (95% CI 1.893–13.785), respectively. Thus, the P143L polymorphism may play a role in causing decreased HDL-C levels, leading to increased risk of dyslipidemia and CAD in Chinese.
