摘　　要：利用流式细胞仪比较PI法和AnnexinV/PI法检测不同时间人肝癌细胞感染蓝舌病毒HbC3的凋亡率分析。结果:PI法在24h、36h、48h的凋亡率分别为10.8±3.05、21.7±6.28、28.3±10.6;AnnexinV/PI法的凋亡率分别为20.42±3.70、49.3±8.11、79.6±11.5。二种方法及不同时间感染病毒细胞的凋亡率之间有显著差异(P<0.01)。证明了AnnexinV/PI法能特异地、准确地检出早期凋亡的细胞、继发性坏死的细胞,BTV-HbC3诱导Hep-3B细胞凋亡是致肿瘤细胞病变、死亡的重要表现形式之一。Flow cytometry was used to quantify the percentage of apoptotic hepatic Caracimoma cells infected with bluetongue virus HbC3 and stained with propidium iodide （PI） and Annexin V/PI. The percentages of the apoptotic cells measured by PI at 24h, 36h and 48h were 10.8 ±3.05, 21.7±6.28, 28.3±10.6, respectively, and those by Annexin V-PI were 20.42±3.70, 49.3±8.11, 79.6±11.5, respectively. The two staining methods and the rate of apoptotic cells infected by bluetengue virus hours were significantly different （P〈0.01）. The early apoptotic cells and secondary necrosis could be detected by AnnexinV/PI assay with good sensitivity and specificity. The apoptotic cells induced by bluetengue virus was one of the important forms in the pathological changes and cell necrosis.
