摘  要:目的 探讨精浆中乙型肝炎病毒(hepatitis B virus,HBV)DNA水平与血清乙型肝炎标志物及精液参数、精子DNA损伤(sperm DNA fragmentation,SDF)的相关性.方法 收集2013年1月至2014年12月于温州医科大学附属第一医院生殖医学中心就诊的148例男性血清乙型肝炎表面抗原(hepatitis B surface antigen,HBsAg)阳性、HBV-DNA拷贝水平>5.0×102U/ml的精液标本.年龄25~40岁,平均32.8岁.荧光定量PCR技术检测其精浆中HBV-DNA拷贝水平,精浆HBV-DNA>5.0×102 U/ml者为阳性组,精浆HBV-DNA≤5.0×102U/ml者为阴性组.比较两组精液参数、精子形态学及SDF情况.结果 148例精液标本中,精浆HBV-DNA阳性组60例,阴性组88例.阳性组中血清乙型肝炎e抗原(hepatitis B e antigen,HBeAg)阳性率为93.3% (56/60),显著高于阴性组的35.2% (31/88,P<0.01).阳性组患者血清HBeAg滴度中位值为845.7(0.2 ~ 1455.0) S/CO,血清HBV-DNA水平为(1.7±1.1) ×108 U/ml;阴性组患者HBeAg滴度中位值为0.1(0.1 ~ 1374.0)S/CO;血清HBV-DNA水平为(2.3±1.1) ×107 U/ml,两组比较差异均有统计学意义(均P<0.05).阳性组患者的精液量(2.4±1.2)ml、精子浓度(66.8 ±49.1)×106/ml、前向运动精子百分数(54.3±16.1)%及正常形态精子数(3.8±2.8)%均显著低于阴性组[分别为(3.1 ±1.3)ml、(87.1±65.4)×106/ml、(59.1±15.3)%和(6.2±4.2)%,均P<0.05],而头部异常的精子数显著高于阴性组(P<0.05).精浆HBV-DNA阳性组中畸形精子症占56.7% (34/60),显著高于阴性组的34.1%(30/88)(x2=7.408,P<0.01).阳性组患者SDF为(18.1±12.3)%,阴性组为(14.4±8.4)%,两组间比较差异有统计学意义(=2.197,P<0.05).结论 男性精浆HBV-DNA拷贝水平与血清HBeAg和HBV-DNA水平存在一定的相关性;当精浆HBV-DNA> 5.0×102 U/ml时可能会对精子活力、正常形态及DNA完整性造成一定的负面影响.Objective To investigate the correlation between seminal plasma hepatitis B virus (HBV) DNA copy and semen parameters and sperm DNA fragmentation (SDF).Methods The seminal plasma HBV-DNA was detected by the real-time PCR in 148 infertility males,and those with serum HBV-DNA above (positive) or below (negative) 5.0 × 102U/ml were analyzed respectively by semen parameters,sperm morphology and sperm DNA fragmentation (SDF).Results Of 148 male,60 (40.5%) were seminal plasma HBV-DNA positive,and of 60 positive patients,56 (93.3%) were serum hepatitis B e antigen(HBeAg) positive,which was higher than those of seminal plasma HBV-DNA negative males (31cases,35.2%).Serum HBeAg and HBV-DNA in seminal plasma HBV-DNA positive patients were 845.7(0.2 ~ 1455.0) S/CO and (1.7 ± 1.1) × 108U/ml,which were higher than those of HBV-DNA negative patients [HBeAg:0.1 (0.1 ~ 1374.0) S/CO;HBV-DNA:(2.3 ± 1.1) × 107 U/ml,P 〈 0.01].Seminal plasma HBV-DNA positive patients exhibited lower semen volume,sperm concentration,the percentage of forward moving sperm and less normal morphology compared to HBV-DNA negative patients [(2.44±1.2)mlvs.(3.07±1.3)ml,(66.8±49.1) ×106/mlvs.(87.1 ±65.4) ×106/ml,(54.3± 16.1)% vs.(59.1 ±15.3)%,(3.77 ±2.8)% vs.(6.15 ±4.2)%,P〈0.05].The number of patients with teratozoospermia was significantly higher in seminal plasma HBV-DNA positive patients (56.7% versus 34.1%,(P 〈 0.01).The SDF in seminal plasma HBV-DNA positive patients was(18.1 ± 12.3)%,while it was(14.4 ± 8.4)% in negative patients,and the difference of SDF in these two groups was significantly (t =2.197,P 〈 0.05).Conclusion Seminal plasma HBV-DNA positive could affect the semen parameters,sperm morphology and SDF.
