This article contains findings obtained from research on animals:
- The results from animal research studies should not be directly applied to humans and the results may not generalise to the human population.
- There may be significant differences between species in terms of physiology, physiology, and pharmacology, as well as differences in the way diseases and treatments are modelled in animals.
- Any conclusions drawn from animal research should be considered with caution and in the context of other types of research studies such as observational studies, clinical trials, and reviews of the literature.

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.
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.

A chronic kidney disease (CKD) rat model was induced by feeding a diet containing 0.75% adenine over a four-week period. Concurrently, the Jian-Pi-Yi-Shen formula was administered every day starting from the third week and continued for four additional weeks. Multiple factors were evaluated including renal injury, fibrotic markers expression, and serum creatinine and blood urea nitrogen levels. The levels of 10 tryptophan metabolites in the rat serum and Aryl hydrocarbon receptor signaling were detected and analyzed using ultra-high performance liquid chromatography-tandem mass spectrometry and Western blot analysis, respectively.
The Jian-Pi-Yi-Shen formula demonstrated significant effects of reducing both serum creatinine and blood urea nitrogen levels and improving renal pathological injuries in the CKD rat model. It was found that the formula also regulated tryptophan metabolism and decreased the levels of tryptophan metabolites in the serum. Furthermore, the formula suppressed the overactivated Aryl hydrocarbon receptor signaling in the kidney. These observations imply that the actions of the Jian-Pi-Yi-Shen formula could effectively protect against CKD.

Animal Study Anaemia Chronic Kidney Disease Erythropoietin
To investigate the effect of Jian-Pi-Yi-Shen (JPYS), chronic kidney disease (CKD) was experimentally induced in rats using a 5/6 nephrectomy. The rats were then administered JPYS orally in both high and low doses for a period of 90 days. Observations were made regarding the serum hepcidin level to assess iron homeostasis. Additionally, the protein expressions of hypoxia inducible factor-2, erythropoietin, ferritin, ferroportin, and the phosphorylation level of extracellular signal-regulated kinase 1/2 were studied using Western blot analysis.
The results showed that JPYS treatment significantly improved kidney function in the CKD rats. Alongside this, pathological kidney damage was found to be significantly restored post-JPYS treatment. The medicine was found to be effective in improving anemia in CKD through the upregulation of red blood cells, hemoglobin, and hematocrit levels. It was also discovered that JPYS stimulates the expressions of erythropoietin and hypoxia-inducible factor-2 proteins in the kidney and liver of the CKD rats, while inducing the phosphorylation of extracellular signal-regulated kinase 1/2 proteins. Furthermore, JPYS was seen to regulate the protein expressions of ferritin and ferroportin in the liver and spleen, as well as in the serum level of hepcidin, suggesting its role in systemic iron recycling.
