Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Calcium oxalate (CaOx) kidney stones are widely acknowledged as the most prevalent type of urinary stones, with high incidence and recurrence rates. Incarvillea diffusa Royle (ID) is a traditionally used medicinal herb in the Miao Minzu of Guizhou province, China, for treating urolithiasis. However, the active components and the underlying mechanism of its pharmacodynamic effects remain unclear. AIM OF THE STUDY This study aimed to investigate the potential inhibitory effect of the active component of ID on the formation of CaOx nephrolithiasis and elucidate the underlying mechanism. MATERIALS AND METHODS In vivo, a CaOx kidney stone model was induced in Sprague-Dawley (SD) rats using an ethylene glycol and ammonium chloride protocol for four weeks. Forty-eight male SD rats were randomly assigned to 6 groups (n = 8): blank group, model group, apocynin group, and low, medium, and high dose of ID's active component (IDW) groups. After three weeks of administration, rat urine, serum, and kidney tissues were collected. Renal tissue damage and crystallization, Ox, BUN, Ca2+, CRE, GSH, MDA, SOD contents, and levels of IL-1β, IL-18, MCP-1, caspase-1, IL-6, and TNF-α in urine, serum, and kidney tissue were assessed using HE staining and relevant assay kits, respectively. Protein expression of Nrf2, HO-1, p38, p65, and Toll-4 in kidney tissues was quantified via Western blot. The antioxidant capacities of major compounds were evaluated through DPPH, O2·-, and ·OH radical scavenging assays, along with their effects on intracellular ROS production in CaOx-induced HK-2 cells. RESULTS We found that IDW could significantly reduce the levels of CRE, GSH, MDA, Ox, and BUN, and enhancing SOD activity. Moreover, it could inhibit the secretion of TNF-α, IL-1β, IL-18, MCP-1, caspase-1, and decreased protein expression of Nrf2, HO-1, p38, p65, and Toll-4 in renal tissue. Three major compounds isolated from IDW exhibited promising antioxidant activities and inhibited intracellular ROS production in CaOx-induced HK-2 cells. CONCLUSIONS IDW facilitated the excretion of supersaturated Ca2+ and decreased the production of Ox, BUN in SD rat urine, and mitigated renal tissue damage by regulating Nrf2/HO-1 signaling pathway. Importantly, the three major compounds identified as active components of IDW contributed to the inhibition of CaOx nephrolithiasis formation. Overall, IDW holds significant potential for treating CaOx nephrolithiasis.

Abstract
INTRODUCTION Sanjin Paishi Decoction (SJPSD) has positive effects on stone prevention; however, there is a lack of convincing evidence in the prevention of calcium oxalate stones. This study aimed investigates the effect of SJPSD on calcium oxalate stones and to explore its mechanism. METHODS The rat model of calcium oxalate stones was established and rats were treated with different doses of SJPSD. The pathological damage of kidney tissues was observed by HE staining, the deposition of calcium oxalate crystals in kidney tissues was examined by Von Kossa staining, and the levels of creatinine (CREA), urea (UREA), calcium (Ca), phosphorus (P), and magnesium (Mg) in serum were analyzed biochemically, the levels of IL-1β, IL-6, and TNF-α in serum were measured by ELISA, and the protein expression of Raf1, MEK1, p-MEK1, ERK1/2, p-ERK1/2, and Cleaved caspase-3 in kidney tissues was analyzed by Western blot. Moreover, the changes in gut microbiota were analyzed by 16S rRNA sequencing. RESULTS SJPSD attenuated the pathological damage of renal tissues, reduced the levels of CREA, UREA, Ca, P, and Mg, and inhibited the expression of Raf1, p-MEK1, p-ERK1/2, and Cleaved caspase-3 in renal tissues (P < 0.05). SJPSD treatment affected the composition of intestinal microbiota in rats with calcium oxalate stones. CONCLUSION The mechanism of SJPSD inhibition of calcium oxalate stone injury in rats may be related to the inhibition of the MAPK signaling pathway and regulation of gut microbiota imbalance.
