该文通过检测６４例肝硬化患者的血小板计数、血块退缩试验、血小板粘附试验、血小板聚集试验和血小板因子Ⅲ活性，发现：２９例（４５．３％）血小板计数减少，另外３５例血小板计数正常患者中，１０例（２８．４％）血小板粘附试验降低，２５例（７１．４％）血小板聚集试验降低，１９例（５４．４％）血小板因子Ⅲ活性减弱，这变化与肝功能损害的程度有关，在肝功能Ｃｈｉｌｄ分级中，Ａ、Ｂ、Ｃ级各组间血小板功能的异常有显著差异（＝１０．１１６４，Ｐ＜０．０１），提示肝硬化患者存在血小板功能异常，血小板功能检查也可作为检测肝功能损害程度的辅助指标。 By detecting platelet count, clot retraction test, platelet adhesion test, platelet aggregation test and platelet factor Ⅲ activity in 64 patients with cirrhosis, we found that in 29 patients (45.3%), the platelet count decreased and the other 35 patients had platelet count Normal patients, 10 cases (28.4%) decreased platelet adhesion test, 25 cases (71.4%) decreased platelet aggregation test, 19 cases (54.4%) platelet factor Ⅲ activity decreased, the change and liver function There was a significant difference in the platelet function among the groups of A, B and C (= 10.1164, P <0.01) in the classification of liver function, which suggested that there was abnormal platelet function in cirrhotic patients, Platelet function tests can also be used as a measure of the extent of liver damage secondary indicators.
