摘要
目的:探讨原发性肝癌(HCC)患者血小板和血浆VEGF含量差异及其意义。方法:采用ELISA与BCA法检测30例HCC患者及10例健康者血小板和血浆VEGF的含量与总蛋白量,进行对比研究。结果:(1)HCC患者血小板VEGF相对值(VEGF含量/样本总蛋白含量)为(235.75±117.47)pg/mg,血浆VEGF相对值为(1.19±0.59)pg/mg,差异具有统计学意义(P<0.05);(2)健康组血小板与血浆VEGF相对值对比,血小板VEGF相对值(73.42±32.54)pg/mg高于血浆VEGF相对值(0.32±0.12)pg/mg,差异有统计学意义(P<0.05);(3)HCC患者血小板VEGF相对值为(235.75±117.47)pg/mg,与健康组(73.42±32.54)pg/mg相比,其相对值高于健康组,差异具有统计学意义(P<0.05);(4)HCC患者血浆VEGF相对值与健康组血浆VEGF相对值对比,HCC患者血浆VEGF相对值(1.19±0.59)pg/mg高于健康组(0.32±0.12)pg/mg,差异无统计学意义(P>0.05)。结论:(1)HCC患者和健康人血小板VEGF相对值都远高于血浆,提示血小板中VEGF相对更浓聚。(2)与健康人相比,HCC患者血小板中VEGF含量明显升高,而两者血浆VEGF含量无统计学差异,提示以血小板为样本,而不是血浆,更有利于发现HCC患者VEGF水平的变化,即可能更早发现肿瘤的生长。
Objective :To evaluate the difference between platelet and serum VEGF level in HCC patients. Methods:Plate- let and serum VEGF,and albumin from 30 HCC and 10 healthy patients were evaluated by ELISA and BCA,and the rela- tionship were evaluated by statistic analysis. Results: ( 1 ) In HCC patients, platelet VEGF relative value ( platelet VEGF/ albumin) was (235.75 ±117.47) pg/mg,and serum VEGF relative value (platelet VEGF/albumin) was (1.19± 0.59) pg/mg, there was significant difference (P 〈 0.05 ). (2)In healthy patients, platelet VEGF value (73.42 ± 32.54) pg/mg was significantly higher than serum VEGF (0.32 ±0. 12) pg/mg ( P 〈 0.05 ). ( 3 ) Platelet VEGF relative value was much higher in HCC patients (235.75 ±117.47 ) pg/mg than healthy patients (73.42± 32.54) pg/mg( P 〈 0.05 ). (4) There was no significant difference of serum VEGF between HCC and healthy patients. Conclusion: ( 1 ) Plate- let VEGF level is much higher than serum both in HCC and healthy patients. (2) Platelet VEGF is increased in HCC pa- tients compared with healthy people, but serum VEGF is with no difference,indicating that platelet VEGF is much more useful for evaluating the invasion of HCC.
