不同类型高脂血症人群肝功能指标的变化趋势

目的探讨不同临床类型高脂血症人群肝功能指标的变化趋势。方法选取2014年7月至2015年7月体检健康人员1 063例(对照组)及不同临床类型的高脂血症患者2 571例,后者又分为高胆固醇血症组258例(高TC组)、高三酰甘油血症组859例(高TG组)、混合型高脂血症组282例(混合组)和低高密度脂蛋白胆固醇血症组1 172例(低HDL-c组),分别检测各组患者血清总蛋白(TP)、清蛋白(ALB)、丙氨酸氨基转移酶(ALT)、天门冬氨酸氨基转移酶(AST)、AST/ALT和球蛋白(GLB)等肝功能指标,进行对比分析。结果高TG组、混合组、低HDL-c组TP和ALB水平与对照组比较均明显降低,差异有统计学意义(P0.05);4组高脂血症患者ALT、AST、AST/ALT、GLB水平较对照组均有不同程度的升高,差异有统计学意义(P0.05);混合组和低HDL-c组TP和ALB水平明显低于高TG组及高TC组,差异有统计学意义(P0.05);低HDL-c组ALT水平明显高于其他3组,差异有统计学意义(P0.05);混合组AST/ALT水平明显高于其他3组,差异有统计学意义(P0.05);高TC组GLB水平明显高于其他3组,差异有统计学意义(P0.05)。结论血脂升高可诱发肝功能损伤,对高脂血症患者进行肝功能指标检测有助于脂肪肝的早期发现和治疗。

Change trend of liver function indicators in different types of hyperlipidemia patients

Objective To investigate the change trend of liver function indicators in different types of hyperlipidemia patients. Methods From July 2014 to July 2015 ,a total of 2571 patients with hyperlipidemia and 1063 normal people(control group) were collected in this research.All patients with hyperlipidemia were divided into the hypercholesterolemia group (high TC group ,n=258) ,hypertriglyceridemia group (high TG group ,n=859) and mixed type hyperlipidemia group(n=282) ,low high-density lipo-protein cholesterol group(low HDL-c group ,n=1172).The liver function indicators of total protein (TP) ,albumin (ALB) ,alanine aminotransferase(ALT ) ,aspartate aminotransferase (AST ) ,AST/ALT and globulin (GLB ) were measured in each group. Results The TP and ALB levels in the high TC group ,mixed group and low HDL group were significantly decreased compared with the control group ,the difference was statistically significant (P<0.05).The ALT ,AST ,AST/ALT and GLB levels in the four hyperlipidemia groups had different degrees of increase as compared with the control group ,the difference was statistically signifi-cant(P<0.05).The TP and ALB levels in the mixed group and the low HDL group were significantly lower than those in the high TG group and high TC group ,the difference was statistically significant (P<0.05).The ALT level in the low HDL group was sig-nificantly higher than that in the other three groups ,the difference was statistically significant (P<0.05).The AST/ALT level in the mixed group was significantly higher than the other three groups (P<0.05).The GLB level in the high TC group was signifi-cantly higher than the other 3 groups with statistical difference (P<0.05).Conclusion Blood lipid increase may induce the liver function injury.The detection of liver function indicators in the patients with hyperlipidemia will contribute to the early detection and treatment of fatty liver.
