Aging-related ED is predominantly attributed to neurovascular dysfunction mediated by NO suppression and increased oxidative stress in penis. The alterations of protein arginine methyltransferases 1 （PRMT1）/dimethylarginine dimethylaminohydrolase （DDAH）/ asymmetrical dimethylarginine （ADMA）/NO synthase （NOS） pathway regulate NO production in the vascular endothelium. Epigallocatechin-3-gallate （EGCG） is one of the most abundant and antioxidative ingredients isolated from green tea. In the present study, 40 Sprague-Dawley rats were randomly distributed into four groups： one young rat group and three aged rat groups treated with daily gavage feedings of EGCG at doses of O, 10 mg kg-1, and 100 mg kg-1 for 12 weeks, respectively. Erectile function was assessed by electrical stimulation of the cavernous nerves with intracavernous pressure （ICP） measurement. After euthanasia, penile tissue was investigated using Western blot and ELISA to assess the PRMTI/DDAH/ADMA/NOS metabolism pathway. Superoxide dismutase （SOD） and malondialdehyde （MDA） levels were detected by colorimetry. We also evaluated smooth muscle contents. The ratio of maximal ICP and mean systemic arterial pressure （MAP） was markedly higher in EGCG-treated aged rats than in untreated aged rats. We found that DDAH 1 and DDAH2 were expressed in cavernosal tissue, and they were downregulated in corpora of aged rats. The administration of EGCG upregulated the expression and activity of DDAH. In contrast, EGCG treatment downregulated the expression of PRMT1 and ADMA content. Moreover, EGCG-treated rats showed an improvement in smooth muscle expression, the ratio of smooth muscle cell/collagen fibril, SOD activity, and MDA levels when compared with untreated aged rats.

目的:评估尿沉渣评分(USS)在急性肾损伤(AKI)的早期诊断、病因鉴别、分期及预后判断中的临床应用,探讨独立的USS及其联合血尿素氮(Bun)、血清肌酐(sCr)和尿酸(UA)对AKI的诊断效能。方法:收集2023年8月23日至9月28日期间吉林大学第一医院住院患者9020份晨尿标本,经Sysmex UF5000检测,筛出小而圆形上皮细胞(SRC)>1/μl和/或管型(CAST)>1/μl 3226份进行尿沉渣镜检,选取肾小管上皮细胞和/或CAST阳性的404例入组,其中男218例,女186例,年龄59.5(49.0,71.0)岁。404例分组方法:依据镜检结果的USS分为USS AKI组(345例)和USS非AKI组(59例);依据改善全球肾脏病预后组织(KDIGO)标准,分为KDIGO标准AKI组(63例)和KDIGO标准非AKI组(341例);依据病历记载的临床诊断,分为临床诊断AKI组(29例)和临床诊断非AKI组(375例);通过查阅病历,对KDIGO标准AKI组按病因分为肾性AKI组(33例)和非肾性AKI组(30例)。采用χ^(2)检验或Fisher精确检验比较不同AKI病因、分期的USS。采用Logistic回归法计算发生肾性AKI及3期AKI的优势比。应用受试者工作特征曲线下面积评价USS、sCr、UA、Bun单独及联合诊断AKI的敏感度、特异度并计算诊断AKI的最佳截断值、敏感度与特异度。结果:以USS对KDIGO标准AKI组进行病因鉴别,肾性与非肾性AKI的USS比较差异有统计学意义(χ^(2)=11.070,P<0.001)。与USS=1相比,当USS≥2分时肾性AKI的优势比为8.125(95%CI 2.208~29.901)。以USS进行AKI分期研究,各期USS的组间比较差异有统计学意义(χ^(2)=15.724,P<0.05)。与USS=1分相比,当USS≥2分时发生3期AKI优势比为9.714(95%CI 1.145~82.390)。独立的USS诊断AKI的AUC为0.687(95%CI 0.618~0.757,P<0.001),特异度65.7%,敏感度61.9%;USS联合Bun、sCr、UA诊断AKI的AUC为0.794(95%CI 0.608~0.980,P<0.05),特异度82.4%,敏感度88.9%。结论:USS≥2分提示发生肾性AKI或3期AKI的可能性增加,USS联合Bun、sCr、UA可提高AKI诊断效能。
