2、居高原组（。=29）和移居高原组（。=34）,对比两组患者的基线资料和接受DPMAS治疗前后的临床特征。符合正态分布的计量资料组间比较采用成组f检验；组内治疗前与治疗后比较应采用配对，检验.非正态分布计量资料组间比较采用Mann-WhitneyU检验；组内治疗前后比较应采用WiICoXon秩和检验。计数资料组间比较采用必检验。KaPlan-Meier法绘制生存曲线，死亡风险比较采用Log-rank检验结果移居高原组汉族比例明显多于世居高原组”=41.729,P0.001）；世居高原组患者最近一次高原连续居住时间明显长于移居高原组（Z=3.364rP0.001）；MELD评分、肝性脑病、肝肾综合
