[摘要]目的：观察聚丙烯酰胺水凝胶(PAMHG)注射后发生并发症者的外周血淋巴细胞的免疫学变化。方法：应用流式细胞分析技术测定注射PAMHG后发生并发症患者的外周血淋巴细胞各个亚群含量变化并与对照组(健康未注射PAMHG)人群相比较。结果：水凝胶组和对照组外周血B淋巴细胞在各个时间组变化趋势一致，组间差异无显著性。外周血T淋巴细胞亚群百分率水凝胶组均存在1～7项不等的指标异常。水凝胶组T3、T4、T8、NK细胞、Tn亚群含量、Ts亚群含量在各个时间组均低于对照组；水凝胶组Tm和Tc亚群在各个时间组均高于对照组。结论：PAMHG作为软组织充填剂注入人体，引起细胞免疫变化，细胞免疫处于增强状态，对机体的长期免疫效应尚需进一步积累病例并长期观察。
