摘要: 目的:探讨六维磷脂治疗酒精相关肾损伤的保护作用及分子机制。  方法:无特定病原体(SPF)级C57BL/6雄性小鼠随机分为3组:对照组(NC)、酒精相关肾损伤组(ETOH)和六维磷脂处理组(ETOH+HexaV)。通过HE、Masson和 PAS染色观察肾脏组织病理变化,利用小鼠肾脏组织进行转录组测序分析,通过实时荧光定量PCR(qPCR)进一步验证相关基因mRNA水平变化。  结果:酒精灌胃8周后,与NC组相比,ETOH组肾脏HE染色可见肾小球萎缩,系膜增殖,间质炎性细胞浸润,肾小管上皮细胞空泡性变性。Masson染色可见蓝色胶原沉积,PAS染色可见紫红色线条增宽。在 ETOH+HexaV组中,上述病理改变减轻。转录组测序结果显示,ETOH组和ETOH+HexaV组中存在27个相同的差异基因。京都基因与基因组百科全书(KEGG)富集分析,慢性酒精暴露主要影响肾素-血管紧张素系统(RAS)、内分泌和其他因子调节的钙重吸收、白细胞介素(IL)-17信号通路,且均在 ETOH组被激活,但在ETOH+HexaV组被逆转。免疫组化结果显示,ETOH组血管紧张素转换酶2(ACE2)表达升高。qPCR结果显示,与NC组相比,ETOH组RAS通路中AgtAce2Ren1Klk1b3上调,IL-17信号通路中IL17dMmp3Mapk10JunRelaCebpdMapk4Cxcl2Cxcl10Lcn2Fosb上调。应用HexaV后上述分子均下调。  结论:HexaV通过逆转慢性酒精激活的炎症及血流动力学通路,从而改善肾脏组织损伤和功能障碍,延缓酒精性肾病进展。

Abstract:

Objective: To explore the protective effects and underlying molecular mechanisms of Hexavitamin Soya Lecithin (HexaV) against alcohol-related renal injury.
Methods: Specific pathogen-free (SPF) male C57BL/6 mice were randomly divided into three groups: control group (NC), alcohol-induced injury model group (ETOH), and HexaV treatment group (ETOH+HexaV). Renal pathological changes were evaluated by hematoxylin-eosin (H&E), Masson’s trichrome and periodic acid-Schiff (PAS) staining. Transcriptomic sequencing was performed on kidney tissues, and the mRNA expression levels of selected target genes were further validated by quantitative real-time polymerase chain reaction (qPCR).
Results: After eight weeks of alcohol gavage, compared with the NC group, H&E staining of kidney tissues in the ETOH group revealed glomerular atrophy, mesangial proliferation, interstitial inflammatory cell infiltration, and vacuolar degeneration of renal tubular epithelial cells. Masson’s trichrome staining showed obvious blue collagen deposition, while PAS staining demonstrated thickened magenta-stained basement membrane structures. All these pathological changes were significantly alleviated by HexaV treatment. Transcriptomic sequencing identified 27 overlapping differentially expressed genes between the ETOH and ETOH+HexaV groups. KEGG enrichment analysis indicated that chronic alcohol exposure predominantly activated the renin—angiotensin system (RAS), endocrine-and other factor-regulated calcium reabsorption, and the interleukin 17 (IL-17) signaling pathway. These pathways were significantly upregulated in the ETOH group but were completely reversed in the ETOH+HexaV group. qPCR further confirmed that, compared with the NC group, RAS-related genes (Agt, Ace2, Ren1, and Klk1b3) and IL-17 signaling pathway-related genes (IL17d, Mmp3, Mapk10, Jun, Rela, Cebpd, Mapk4, Cxcl2, Cxcl10, Lcn2, and Fosb) were significantly upregulated in the ETOH group, and all these changes were reversed following HexaV intervention.
Conclusion: HexaV improves alcohol-induced renal tissue damage and dysfunction, and delays the progression of alcoholic nephropathy by reversing the inflammatory and hemodynamic pathways activated by chronic alcohol exposure.
