高血压肾功能损害患者血清中转化生长因子β1含量检测及其临床价值分析

摘要

目的：研究高血压肾功能损害患者血清中转化生长因子β1(TGF-β1)含量检测及其临床价值。方法：筛选150例原发性高血压患者，根据病情将其分为3组：①原发性高血压未合并靶器官功能损害的患者为对照组(50例)；②原发性高血压合并肾功能损害Ⅰ期的患者为肾功能Ⅰ期组(50例)；③原发性高血压合并肾功能损害Ⅱ期的患者为肾功能Ⅱ期组(50例)。比较3组受试者的血清TGF-β1含量以及肾功能指标。结果：3组受试者的血肌酐(Scr)和血尿素氮(Urea)水平相比，无统计学差异；肾功能Ⅰ期组、Ⅱ期组患者的内生肌酐清除率(Ccr)低于对照组；TGF-β1水平高于对照组，差异有统计学意义(F=23.523，P＜0.05)；TGF-β1水平与Ccr呈负相关关系。结论：当肾功能损害为Ⅰ期、Ⅱ期时，TGF-β1水平发生明显改变，且与菊粉清除率(Cin)水平具有良好的相关性，是反应肾功能的理想指标。%Objective:To detect the levels of TGF-β1 in hypertensive renal function impairment patients and its clinical value. Methods: Primary hypertension patients with no target organs damage were enrolled in control group, primary hypertension patients with renal function stageⅠand stageⅡwere enrolled in renal function stageⅠgroup and stageⅡgroup. Serum TGF-β1 levels and renal function indices of three groups were compared. Results:There were no significant difference of serum creatinine and blood urea nitrogen of three groups(F=23.523, P<0.05);endogenous creatinine clearance rate of renal functionⅠandⅡgroups were lower than that of control group, TGF-β1 levels of renal functionⅠandⅡ groups were higher than of control group; TGF-β1 levels were negatively correlated with creatinine clearance rate. Conclusion:TGF-β1 level is an ideal index to reflect renal function for its level significantly changes in renal damage stageⅠ,Ⅱand has good correlation with Cin.
