乙型肝炎免疫球蛋白聚氰基丙烯酸正丁酯纳米粒抑制HBsAg、HBV DNA分泌的体外实验

目的 研究乙型肝炎免疫球蛋白聚氰基丙烯酸正丁酯纳米粒(HBIG-PBCA-NP)对HBV感染细胞模型HBsAg、HBV DNA分泌的抑制作用.方法 用含HBIG-PBCA-NP及乙型肝炎免疫球蛋白(HBIG)的培养基培养HepGg.2.15细胞,或先以一定浓度的上述两种药物培养,第3天后更换为不含相应药物的培养基继续培养细胞,在不同时间点定量检测堵养上清液HBsAg、HBV DNA.组间比较采用t检验和方差分析.结果 0.1～10.0 IU/mL的HBIG-PBCA-NP及HBIG在不同时间点均能抑制HepG2.2.15细胞培养上清液HBsAg、HBV DNA的分泌,与对照组比较差异有统计学意义.HBIG-PBCA-NP组与HBIG组在无药物继续培养的上清液中,HBsAg浓度与HBVDNA水平在第5、7天继续下降,第9、11天逐步增高,其中0.1、1.0、5.0 IU/mL HBIG-PBCA-NP组与同浓度HBIG组比较,培养上清液中的HBsAg浓度在第9天为(31.31±1.98)μg/L比(40.62±2.99)μg/L、(23.79±1.31)μg/L比(36.51±2.12)μg/L、(19.91±1.74)μg/L比(33.03±1.65)μg/L(F=412.24,P＜0.01).5.0 IU/mL的HBIG-PBCA-NP组与同浓度的HBIG组比较,培养上清液中HBV DNA水平在第7天为(3.41±0.27)lg拷贝/mL比(6.56±0.19)lg拷贝/mL(t=14.75,P＜0.01);第9天为(5.16±0.37)lg拷贝/mL比(6.87±0.30)lg拷贝/mL(t=7.71,P＜0.01);第11天为(6.40±0.33)lg拷贝/mL比(7.74±0.35)lg拷贝/mL(t=5.99,P＜0.01).结论 在体外细胞实验中,HBIG-PBCA-NP能抑制HBsAg、HBV DNA的分泌,且较原药HBIG作用有增强趋势.
