The herbal decoction Jian-Pi-Yi-Shen reduces symptoms of chronic kidney disease and anaemia by improving iron metabolism and inhibiting the JAK2-STAT3 signaling pathway.
2023 Journal of Ethnopharmacology Jian-Pi-Yi-Shen formula restores iron metabolism from dysregulation in anemic rats with adenine-induced nephropathy Li C, Huang H, Wang R, Zhang C, Huang S, Wu J, et al.
Experimental Study Anaemia Chronic Kidney Disease Jian Pi Yi Shen Formula
Methodology used included an analysis of network pharmacology, chemical profiling, and in vivo experiments on the effect of Jian-Pi-Yi-Shen (JPYS) on renal anemia and chronic kidney disease (CKD). The active compounds in JPYS were detected in in vivo experiment, and their potential targets were predicted by network pharmacology. An animal model of CKD-related anemia was developed using adenine-feeding for further analysis. The estimation of renal injury was conducted using blood tests, histopathological examinations, and fibrosis degree assessment while the levels of JAK2, STAT3 and iron metabolism-related factors were measured through various techniques.
Discussion of the results reveals that 164 active ingredients, including prototypes and metabolites in JPYS, were discovered and 21 core targets were identified. Many of these core targets were associated with the JAK2-STAT3 signaling pathways. Experimental results demonstrated that JPYS treatment significantly improved hematological parameters and iron metabolism in CKD rats, decreased certain indicators of renal damage, and suppressed the expression of JAK2 and STAT3.
Jian-Pi-Yi-Shen formula has shown potential in delaying kidney deterioration in chronic kidney disease by rejuvenating the process of creating nicotinamide adenine dinucleotide.
2023 Aging Jian-Pi-Yi-Shen formula alleviates renal fibrosis by restoring NAD+ biosynthesis in vivo and in vitro Gao L, Huang X, Deng R, Wu S, Peng Y, Xiong G, et al.
Experimental Study Chronic Kidney Disease Jian Pi Yi Shen Formula Renal Fibrosis
The study was conducted utilizing an adenine-diet feeding model for inducing chronic kidney disease in a breed of mice. For 4 weeks, these mice were given Jian-Pi-Yi-Shen formula orally. Human proximal tubular epithelial cells were stimulated with a growth factor, with or without the formula. Assessments were made of renal function via serum creatinine and blood urea nitrogen levels, with renal histopathological changes evaluated through specific staining techniques. Further, cell viability and NAD+ concentrations were monitored with assay kits.
The Jian-Pi-Yi-Shen formula did not only help in the improvement of renal function and reduction of pathological injury but it also inhibited renal fibrosis in the mice with chronic kidney disease. Moreover, the same formula was found to reverse fibrotic responses induced by a growth factor in human proximal tubular epithelial cells. Importantly, the formula was observed to recover the decreased NAD+ content in the chronic kidney disease mice and the human cells, bringing about the restoration of the expression of vital enzymes in the NAD+ synthesis process.
Extra virgin olive oil high in minor polar compounds significantly improves kidney function, reduces oxidative stress, inflammation, and ultimately benefits the body composition.
2021 Nutrients Usefulness of Extra Virgin Olive Oil Minor Polar Compounds in the Management of Chronic Kidney Disease Patients Noce A, Marrone G, Urciuoli S, Di Daniele F, Di Lauro M, Pietroboni Zaitseva A, et al.
Experimental Study Chronic Kidney Disease
The research study tested two distinct types of extra virgin olive oils, namely Synergy with a high content and Luxolio with a medium content of minor polar compounds, on 40 patients suffering from kidney disease. The patients were administered a 40 mL dosage per day over nine weeks. Researchers assessed the impacts on renal functionality, oxidative stress, inflammation levels, and body composition, before and after a subsequent two-month wash out period. Additionally, the concentration of minor polar compounds in the oils was determined through high-performance liquid chromatography accompanied by diode-array detection and mass spectrometry (HPLC-DAD-MS).
The research showed improvements in kidney function indicators such as estimated glomerular filtration rate, albuminuria, azotemia, and uric acid. Further, the patients' lipid profile also improved, as did their inflammation parameters, erythrocyte sedimentation rate, C-reactive protein, and body composition. More notably, these beneficial effects were stronger and lasted longer in those patients who had been given the Synergy oil, indicating a sustained antioxidant and anti-inflammatory impact from EVOOs with higher concentrations of minor polar compounds.
Consuming coffee is associated with lower risks of developing chronic kidney disease, reaching end-stage kidney disease, and having albuminuria.
2021 Journal of Renal Nutrition Effect of Coffee Consumption on Renal Outcome: A Systematic Review and Meta-Analysis of Clinical Studies Kanbay M, Siriopol D, Copur S, Tapoi L, Benchea L, Kuwabara M, et al.
Systematic Review Albuminuria Chronic Kidney Disease
In this systematic review and meta-analysis, researchers conducted a comprehensive literature search through various databases, including PubMed/Medline, Web of Science, Embase by Elsevier, and the Cochrane Central Register of Controlled Trials by Wiley from 1960 until February 2020. Outcomes related to chronic kidney disease incidence, its progression, and mortality associated with this disease were evaluated and correlated with coffee consumption and the amount consumed. Quality assessment of the included studies was done using the Newcastle-Ottawa scale.
The analysis incorporated 12 studies, with a mix of prospective and cross-sectional studies, and a total of 505,841 subjects. Seven of these studies focused on the relationship between coffee consumption and the onset of chronic kidney disease. The finding was that consuming coffee was significantly correlated with a decrease in the risk for this disease, especially for individuals who took more than 2 cups of coffee per day. Furthermore, there was also a noteworthy lower risk of reaching end-stage kidney disease for coffee drinkers, as well as a decrease in the risk of albuminuria (a kidney disease marker). Finally, the risk of death related to chronic kidney disease was discovered to be lower in coffee consumers.
The Jian-Pi-Yi-Shen (JPYS) traditional Chinese medicine formula aids in the alleviation of renal dysfunction and fibrosis in chronic kidney disease (CKD) rats by combating inflammation and cellular apoptosis.
2021 Frontiers in Pharmacology Jian-Pi-Yi-Shen Formula Ameliorates Oxidative Stress, Inflammation, and Apoptosis by Activating the Nrf2 Signaling in 5/6 Nephrectomized Rats Zhou F, Zou X, Zhang J, Wang Z, Yang Y, Wang D
Experimental Study Chronic Kidney Disease Jian Pi Yi Shen Formula
Using an established model of 5/6 nephrectomized (5/6Nx) rats, an evaluation of the effects of the JPYS formula on renal function and fibrosis was conducted. To scrutinize the formula's impacts, markers of apoptosis, inflammation, oxidative stress, and the activity of Nrf2 signaling were measured. Correlative parameters including urinary protein, SCr, BUN, glomerular sclerosis index, tubulointerstitial fibrosis score, and renal histopathology were analyzed to assess the formula's preventive effect on renal dysfunction and fibrosis. The study also evaluated the gene expression associated with fibrosis and related elements such as TGF-β and various types of collagen.
The evaluation of JPYS's efficacy revealed significant protection against cell apoptosis, highlighted by altered gene expression of Bcl-2, Bax, caspase 3, caspase 9, and the number of TUNEL-positive cells. Moreover, it was observed that the JPYS formula countered the activation of the NF-κB-mediated inflammatory pathway, exhibiting a decrease in gene expression of numerous inflammatory markers in the kidney. Alongside this, the formula promoted antioxidant performance, alleviating oxidative stress as indicated by antioxidant index indicators and a reduction in reactive oxygen species biomarkers. The study also identified the upswing of essential elements like HO-1 and Nrf2 level and a decline in Keap1 expression, signaling rationale towards the formula's potential relief of renal oxidative damage.
