摘要
目的:探讨中国人血小板无力症患者的临床和病理特点。方法:分析了25 例血小板无力症的临床表现、代偿机制、实验室检查、分子基础、治疗和预防措施。结果:25 例血小板无力症患者Ⅰ型20 例,Ⅱ型2 例,变异型3 例,已鉴定出血小板膜糖蛋白GPⅡb,Ⅲa 基因6 种类型分子缺陷,包括错义突变、无义突变、剪接点突变和小片段DNA丢失。结论:出血症状严重程度和分子缺陷之间无明显关系。
Objective:To investigate clinical and pathological features in chinese patients with Glanzmann thrombasthenia.Method:Data of 25 GT patients were retrospectively studied,including clinical demonstration,lab findings,possible compensative mechanism,medical treatment and preventing for GT patients.Results:Among 25 patients,20 were classified as type Ⅰ,2 as type Ⅱ and 3 as variant GT patients.6 different kinds of molecular defects of platelet GP Ⅱb,Ⅲa genes were identified,which included missense mutation,non sense mutation,splice site mutation and deletion of small fragment DNA.Conclusion:There was no correlation between the type of molecular defect and the severity of hemorrhage.
