摘　　要：目的:研究龟鹿二仙胶对雷公藤多苷(GTW)诱导弱精子症(AZS)大鼠精子线粒体结构和功能及溶质载体家族22成员14(SLC22A114)表达的影响。方法:60只SD大鼠随机分为正常组,模型组,龟鹿二仙胶低、中、高剂量组、五子衍宗丸组,各10只;除正常组外,各组均给予GTW40mg·kg^(-1)·d^(-1)连续灌胃4周造模AZS大鼠模型;造模结束后正常组、模型组给予0.9%氯化钠溶液灌胃4周,龟鹿二仙胶低、中、高剂量组分别给予龟鹿二仙胶混悬液0.25、0.50、1.00g·kg^(-1)·d^(-1),五子衍宗丸组给予1.00g·kg^(-1)·d^(-1)五子衍宗丸混悬液,灌胃4周;采用HE染色观察睾丸组织形态;计算机辅助精子分析检测大鼠精液质量;流式细胞术分析检测精子线粒体膜电位;透射电镜观察精子线粒体结构;实时荧光定量聚合酶链式反应和蛋白免疫印迹法检测精子线粒体SLC22A114蛋白及mRNA表达。结果:龟鹿二仙胶可减轻AZS大鼠模型睾丸组织病理损伤,改善精液质量,且龟鹿二仙胶高剂量组可显著改善精子浓度、精子活力、活动精子数(P<0.01);龟鹿二仙胶可提高AZS大鼠精子线粒体膜电位(P<0.05,P<0.01),并可改善其结构;龟鹿二仙胶高剂量组可上调AZS大鼠精子线粒体SLC22A14蛋白及mRNA表达(P<0.05,P<0.01)。结论:龟鹿二仙胶可通过上调GTW诱导AZS大鼠模型精子线粒体SLC22A14蛋白及mRNA表达,进而改善精子线粒体结构和功能,提高精子活力。Objective:To study the effects of Guilu-Erxian-Glue on the structure and function of sperm mitochondria and the expression of solute carrier family 22 member 14(SLC22A114)in asthenospermia(AZS)rat model induced by Tripterygium wilfordi polyglycosid(GTW).Methods:Sixty SD rats were randomly divided into normal group,model group,Guilu-Erxian-Glue low,medium and high dose group and Wuzi-Yanzong-Pill group,with 10 rats in each group;In addition to the normal group,each group was given Tripterygium wilfordi polyglycoside 40 mg·kg^(-1)·d^(-1)for 4 weeks to induce the AZS rat model;After modeling,the normal and model group were given 0.9%sodium chloride solution by gavage for 4 weeks,and the Guilu-Erxian-Glue low,medium,high group were given 0.25,0.50,1.00 g·kg^(-1)·d^(-1)Guilu-Erxian-Glue,Wuzi-Yanzong-Pill group were given 1.00 g·kg^(-1)·d^(-1)Wuzi-Yanzong-il,suspension by gavage for 4 weeks;The morphology of testis was observed by HE staining;The sperm quality was detected by computer-aided sperm analysis;Sperm mitochondrial membrane potential was detected by flow cytometry;The morphology of sperm mitochondria were observed by transmission electron microscope;The protein and mRNA expressions of SLC22A14 of sperm mitochondria were detected by real-time PCR and western blot.Results:Guilu-Erxian-Glue could mitigate the pathological damage of testicular tissue and improve the sperm quality of epididymis in the AzS rat model,Guilu-Erxian-Glue high dose group could improve the sperm concentration,sperm motility,and mobile sperm counts(P<0.01);Guilu-Erxian-Glue could increase the sperm mitochondrial membrane potential(P<0.05,P<0.01)and improve its structure;Guilu-Erxian-Glue high dose group could up-regulate the protein and mRNA expressions of SLC22A14 of sperm mitochondria(P<0.05,P<0.01).Conclusion:Guilu-Erxian-Glue could up-regulate the expression of protein and mRNA of sperm mitochondria SLC22A14 in the AZS rat model induced by Tripterygium wilfordi polyglycoside,so as to improve the structure and function of sperm m
