摘要
目的探讨男性不育患者精液质量与精浆微量元素水平及精浆外泌体(exosome)miR-184水平的关系。方法选取2022年1月至2023年7月155例男性不育患者为不育组,另选同期155例男性体检正常者为正常组。比较两组一般资料、精液质量参数、微量元素、外泌体中miR-184水平,另通过Spearman秩相关分析男性不育患者与上述实验室指标的相关性。结果不育组精子浓度、精子总活力(PR+NP)、前向运动精子(PR)、精子平均曲线运动速度、精子平均直线运动速度、精子平均路径运动速度、精子头部侧向平均振幅(ALH)低于正常组(P<0.05);不育组Zn、Mg、Ca水平低于正常组,Cu、Pb水平及miR-184相对表达量高于正常组(P<0.05);男性不育患者Zn、Cu元素水平分别与精子浓度、精子总活力(PR+NP)、前向运动精子(PR)呈正、负相关,Pb元素水平与精子头部侧向平均振幅(ALH)呈负相关,且P<0.05。男性不育患者miR-184相对表达量与精子浓度、精子总活力(PR+NP)、前向运动精子(PR)、精子平均曲线运动速度呈负相关,且P<0.05。结论男性不育患者精液质量与精浆微量元素水平及外泌体中miR-184水平联系密切。
Objective Explore the relationship between semen quality and trace element levels in seminal plasma,as well as miR-184 levels in exosomes of male infertility patients.Methods 155 male infertility patients in our hospital from January 2022 to July 2023 were selected as the infertility group,and another 155 male patients with normal physical examination during the same period were selected as the normal group.Compare the general information,semen quality parameters,trace elements,and miR-184 levels in exosomes between two groups,and analyze the correlation between male infertility patients and the above laboratory indicators through Spearman rank correlation analysis.Results The sperm concentration,total sperm motility(PR+NP),forward motility sperm(PR),average curve velocity,average linear velocity,average path velocity,and average lateral amplitude of sperm head(ALH)in the infertile group were lower than those in the normal group(P<0.05);The levels of Zn,Mg,and Ca in the infertile group were lower than those in the normal group,while the levels of Cu,Pb,and relative expression of miR-184 were higher than those in the normal group(P<0.05);The levels of Zn and Cu elements in male infertility patients are positively and negatively correlated with sperm concentration,total sperm motility(PR+NP),and forward motility sperm(PR),respectively.The levels of Pb elements are negatively correlated with the average lateral amplitude of sperm head(ALH),and P<0.05.The relative expression level of miR-184 in male infertility patients is negatively correlated with sperm concentration,total sperm motility(PR+NP),forward motility sperm(PR),and average sperm curve velocity,with P<0.05.Conclusion The quality of semen in male infertility patients is closely related to the levels of trace elements in semen and miR-184 levels in exosomes.
