摘要: 目的: 乙肝患者的精子活力降低且有较高比例的凋亡和坏死,但其机制未明。本研究主要考察乙肝病毒表面蛋白(HBs)对人精子线粒体膜电位的影响。 方法:对经不同浓度的HBs(0、25、50、100 μg/ml)孵育4 h后的人精子活力进行分析,并进一步采用JC-1染料结合流式细胞术监测人精子线粒体膜电位的变化。 结果: 与对照组比较,人精子在体外加入100 μg/ml HBs孵育后,a+b级精子数比例显著下降(P<0.01),精子线粒体膜电位显著下降,25、50、100 μg/ml HBs处理组丧失线粒体膜电位的精子百分率分别为24.83%、44.43%和92.22%。 结论: 乙肝病毒可能通过表面蛋白HBs对人精子活力和线粒体膜电位产生负面影响。

Abstract: OBJECTIVE: Sperm of HBV patients displayed lower motility and higher ratio of apoptosis and necrosis when compared with those of normal persons. The mechanisms involved in the process, however, remain obscure. This article was aimed at investigating the influence of hepatitis B virus surface protein (HBs) on sperm mitochondrial membrane potential (MMP). METHODS: Sperm motility was analyzed after incubation with HBs in vitro. Sperm MMP was assayed by using JC-1 dyeing and flow cytometry. RESULTS: The percentage of sperm class a+b significantly decreased after incubation with 100 μg/ml HBs in vitro. CONCLUSION: HBV might adversely impact on sperm motility and MMP by HBs protein.
