【摘要】目的 研究低分子量肝素(LMWH)对血液透析(血透)患者血小板平均体积(MPV)和α颗膜粒膜蛋白(GMP-140)的影响。方法 对45例维持性血透患者分别使用LMWH和标准肝素(SH)抗凝,分别测定透析前、透析后15、30、60、120、240分钟时活化的部分凝血酶时间(APTT)和凝血酶时间(TT)及血小板计数(BPC)、MPV、GMP-140并作比较。结果 SH组APTT和TT在透析120及240分钟时较之LMWH组显著延长(P均<0.001),透析15分钟后SH组MPV、GMP-140较透析前及LMWH组有极显著增高(P均<0.01)。结论 SH是引起血透过程中血小板活化的重要因素之一,LMWH能显著改善这种状况。

【Abstract】Objectives To investigate the effect of low molecular weight heparin on mean platelet volume(MPV)and alpha-granule membrane protein(GMP-140)in patients with hemodialysis(HD).Methods 45 patients with HD were treated with same HD fashion and used either with low molecular weighyt heparin(LMWH)or standard heparin(SH).The active partial thromboplasin time (APTT),thrombin time(TT),BPC,MPV,GMP-140 were measured at prior-HD and 15,30,60,120,240 minutes after HD,respectively.Results APTT and TT were markedly prolongated at 120,240 minutes after HD in SH group than those in LMWH group(all P<0.001).MPV and GMP-140 were much significantly higher at 15 minutes after HD in SH than those in LMWH group (all P<0.01).Conclusion The SH might be an important factor contributing to platelet activation and that LMWH can improve platelet activation during HD.

长期以来,人们对血液透析(血透)过程中补体激活、白细胞减少、血小板减少以及一些细胞因子水平的变化,大多认为是受膜的生物相容性等影响,而往往忽略了抗凝剂肝素的影响。我们对45例使用低分子量肝素(LMWH)抗凝的血透患者的血小板平均体积(MPV)及血小板α颗粒膜蛋白(GMP-140)水平进行了观察,并与标准肝素(SH)作对比研究。现报道如下。
对象与方法
一、对象:45例均系慢性肾小球肾炎终未期肾功能衰竭的维持性血透患者,其中男性29例,女性16例,年龄23~68(平均35.3±9.5)岁,透析时间12~108(平均32.1±10.0)个月。研究期间均未使用影响血小板功能的药物。所有病人病情稳定,无出血倾向。
