Objective To investigate the potential roles of miR-127-3p and miR-129-5p in guiding micro-blood stasis syndrome differentiation, predicting renal pathological outcomes, assessing disease activity, and evaluating prognosis in IgA nephropathy (IgAN) patients. Methods Thirty IgAN patients meeting the diagnostic criteria of "micro-blood stasis syndrome" were enrolled from Hangzhou Hospital of Traditional Chinese Medicine between September 2020 and December 2021. Plasma levels of miR-127-3p and miR-129-5p were measured, and their correlations with renal pathological indices (including activity index and chronicity index) and laboratory parameters (including liver function indicators, renal function indicators, coagulation function indicators, urinary markers,and lipid profiles) were analyzed. Results (1) Activity index:No significant correlation was observed between miR-127-3p expression and any activity indices (P>0.05) . miR-129-5p expression showed a positive correlation with mesangial hypercellularity index (MsHI) (r = 0.470,P = 0.009) but had no significant correlations with endocapillary hypercellularity index (endoI) ,glomerular capillary loop destruction activity index (dGAI) ,or mesangial matrix expansion index (MsMT) (P>0.05) . (2) Chronicity index:Neither miR-127-3p nor miR-129-5p expression correlated significantly with glomerular chronicity index (GCI),tubular chronicity index (TCI) (P>0.05) . (3) Liver function: miR-127-3p showed no significant correlation with alanine aminotransferase (ALT), aspartate aminotransferase (AST), or albumin (ALB) (P>0.05) . miR-129-5p expression was negatively correlated with ALB (r = -0.388,P = 0.034) and positively correlated with AST (r = 0.448,P = 0.013),but was not correlated with ALT (P>0.05) . (4) Renal function:No significant correlations were found between miR-127-3p/miR-129-5p and blood urea nitrogen (BUN),serum creatinine (Scr),uric acid (UA),creatinine clearance rate (CCr),or cystatin C (Cys-C) (P>0.05) . (5) Coagulation function: Neither miR-127-3p/miR-129-5p was correlated with prothrombin time (PT),activated partial thromboplastin time (APTT) ,thrombin time (TT) ,fibrinogen (FIB) ,or D-dimer (D-D) (P>0.05) . (6) Urinary markers:No significant correlations were observed with 24-hour urinary protein quantification (24hUPQ) or urinary N-acetyl- β-D-glucosaminidase-to-creatinine ratio (UNAG/UCr) (P>0.05) . (7) Lipid profiles:Neither miR-127-3p/miR- 129-5p showed significant correlations with triglycerides ( TG ) ,total cholesterol (TC) ,or low-density lipoprotein cholesterol (LDL-C) (P>0.05) . Conclusion In IgAN patients with micro-blood stasis syndrome,miR-129-5p demonstrates potential in reflecting renal pathological damage and shows prospects for evaluating disease activity and prognosis. These findings suggest its potential value in guiding integrated Chinese and western medicine diagnosis and treatment of IgAN.
