男性不育患者精浆中性粒细胞弹性蛋白酶浓度对精子质量的影响

目的探讨男性不育患者精子的质量与精浆中性粒细胞弹性蛋白酶的相关性。方法检测130例不育男性的中性粒细胞弹性蛋白酶浓度,根据精液中性粒细胞弹性蛋白酶浓度将研究对象分为三组,大于1 000ng/mL为A组,250~1 000ng/mL为B组,小于250ng/mL为C组,对各组精浆中的精液基本参数和生化指标(酸性磷酸酶、枸橼酸、锌和果糖)进行测定。结果 (1)A、B、C三组间,精液密度和精子活动率差异有统计学意义(P0.05),且中性粒细胞弹性蛋白酶浓度与精液密度(r=-0.43)和精子活动率(r=-0.37),精液体积及正常精子形态差异无统计学意义(P0.05);(2)A、B、C三组间,酸性磷酸酶、柠檬酸和锌浓度差异有统计学意义(P0.05),且中性粒细胞弹性蛋白酶的浓度与磷酸酶(r=-0.19)、柠檬酸(r=-0.17)和锌(r=-0.23)的浓度呈显著负相关,三组间果糖浓度差异无统计学意义(P0.05)。结论精液中性粒细胞弹性蛋白酶的水平与精液密度、精子活动率及生化指标参数(酸性磷酸酶、柠檬酸和锌)呈显著负相关,提示精液中性粒细胞弹性蛋白酶对精子的质量有负面的影响,进而影响男性的生育能力。

Influence of neurtophil elastase on sperm quality in male infertile patients

Objective To explore the relationship between sperm quality and neurtophil elastase (NE) in male infertile patients . Methods the NE concentration was detected in1 30 male infertile patients ,the research subjects were classified into 3 groups based on the neurtophil elastase concentration :neurtophil elastase concentration more than 1 000 ng/mL (group A ) ,250-1 000 ng/mL (group B) less than 250 ng/mL (group C) .Then sperm basic parameters and biochemical markers (phosphatase ,citrate ,zinc and fructose) were detected .Results (1) The sperm density and motility showed statistically significant differences among the group A ,B and C(P<0 .05)moreover neutrophil elastase concentration was negatively correlated with sperm density (r= -0 .43) and sperm motility(r= -0 .37) .Sperm volume and morphology showed no statistically significant differences among three groups (P>0 .05) .(2) There were statistically significant differences in the levels of phosphatase ,citrate and zinc among three groups (P<0 .05) ,moreover the neutrophil elastase concentration had significantly negative correlation with the concentrations of phosphatase , citrate and zinc(r= -0 .19 ,r= -0 .17 ,r= -0 .23) ,while the fructose concentration had no statistical difference among three groups(P>0 .05) .Conclusion The NE level in semen has significant reverse correlation with sperm density ,sperm motility and bi‐ochemical markers (phosphatase ,citrate and zinc) ,implying that semen NE has significantly negative effect on the sperm quality , thus affecting male fertility ability .
