ObjectiveTo observe the effects of Tongluo Baoshen prescription (TLBS)-containing serum on the rat podocyte injury induced by lipopolysaccharide (LPS) and explore the potential mechanisms. MethodsSD rats were used to prepare the blank serum, losartan potassium-containing serum, and low-, medium-, and high-dose TLBS-containing sera. Rat podocytes were cultured in vitro, and the effects of drug-containing sera on podocyte viability were detected by the cell counting kit-8 (CKK-8) method. The optimal intervention volume fraction of drug-containing sera and the optimal concentration of LPS for inducing the podocyte injury were determined. Rat podocytes were grouped as follows: normal control (NC, 10% blank serum), model control (MC, 20.00 mg·L-1 LPS+10% black serum), losartan potassium (LP, 20.00 mg·L-1 LPS+10% losartan potassium-containing serum), low-dose TLBS (TLBS-L, 20.00 mg·L-1 LPS+10% low-dose TLBS-containing serum), medium-dose TLBS (TLBS-M, 20.00 mg·L-1 LPS+10% medium-dose TLBS-containing serum), and high-dose TLBS (TLBS-H, 20.00 mg·L-1 LPS+10% high-dose TLBS-containing serum), and the interventions lasted for 48 h. The ultrastructure of podocytes was observed under a transmission electron microscope. The podocyte apoptosis was detected by the terminal deoxynucleoitidyl transferase mediated nick-end labeling (TUNEL) kit. Immunofluorescence was used to detect the expression of gasdermin D N-terminal fragment (GSDMD-NT) in podocytes. The mRNA and protein levels of G protein-coupled receptor family C group 5 member B (GPRC5B), nuclear factor-κB (NF-κB) p50, NF-κB p52, NF-κB p65, Rel B, c-Rel, NOD-like receptor protein 3 (NLRP3), cysteinyl aspartate-specific protease-1 (Caspase-1), GSDMD-NT, interleukin (IL)-1β, IL-18, nephrin, integrin α3, and integrin β1 in podocytes were determined by real-time quaritiative polymerase chain reaction (Real-time PCR) and Western blot, respectively. ResultsCompared with the NC group, the MC group showed reduced podocyte protrusions and organelles, segmental missing of cell membranes, increased and swollen mitochondria, irregular nuclear membranes, light chromatin, increased TUNEL fluorescence-positive nuclei (P<0.01), obviously enhanced fluorescence intensity of GSDMD-NT, up-regulated mRNA and protein levels of GPRC5B, NF-κB p50, NF-κB p52, NF-κB p65, Rel B, c-Rel, NLRP3, caspase-1, GSDMD-NT, IL-1β, and IL-18 (P<0.01), and down-regulated mRNA and protein levels of nephrin, integrin α3, and integrin β1 (P<0.01) in podocytes. Compared with the MC group, the LP, TLBS-M, and TLBS-H groups showed improved ultrastructure of podocytes with increased protrusions, intact cell membranes, reduced organelles, and alleviated mitochondrial swelling, decreased TUNEL fluorescence-positive nuclei (P<0.01), weakened fluorescence intensity of GSDMD-NT, down-regulated mRNA and protein levels of GPRC5B, NF-κB p50, NF-κB p52, NF-κB p65, Rel B, c-Rel, NLRP3, caspase-1, GSDMD-NT, IL-1β, and IL-18 (P<0.01), and up-regulated mRNA and protein levels of nephrin, integrin α3, and integrin β1 (P<0.05, P<0.01). Moreover, the changes above were the most obvious in the TLBS-H group. ConclusionThe TLBS-containing serum can regulate the GPRC5B/NF-κB/NLRP3 pathway to inhibit pyroptosis, thereby ameliorating the podocyte injury induced by LPS.

IgA nephropathy is recognized as the most common primary glomerular disease, with up to 20%-40% of patients developing end-stage kidney disease within 20 years of onset. The deposition of IgA1-containing immune complexes targeting glycosylation defects in the mesangial region and the subsequent inflammation caused by T lymphocyte activation are considered as the main causes of IgA nephropathy, and innate immunity is also involved in the pathogenesis. Nucleotide-binding oligomerization domain (NOD)-like receptor protein 3 (NLRP3) is a newly discovered pattern recognition receptor expressed in renal intrinsic cells such as renal tubular epithelial cells, mesangial cells, and podocytes. Activated by external stimuli, NLRP3 can form NLRP3 inflammasomes with apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC). The NLRP3 inflammasome can activate cysteine aspartate-specific protease-1 (Caspase-1), causing the maturation and release of interleukin-18 (IL-18) and interleukin-1β (IL-1β) involved in inflammation. Increasing evidence has suggested that NLRP3 inflammasomes are involved in the pathogenesis and progression of IgA nephropathy and associated with the damage of renal intrinsic cells such as podocytes, mesangial cells, endothelial cells, and renal tubular epithelial cells. Chinese medicine can regulate inflammatory cytokines and their signaling pathways by acting on NLRP3 inflammasomes and related molecules, exerting therapeutic effects on IgA nephropathy. This article introduces the role of NLRP3 inflammasomes in IgA nephropathy and reviews the clinical and experimental research progress of Chinese medicine intervention in IgA nephropathy via NLRP3 inflammasomes, aiming to provide a reference for further research and application of Chinese medicine intervention in the NLRP3 inflammasome as a new therapeutic target.

ObjectiveTo explore the mechanism of Bushen Huoxue enema in treating the rat model of kidney deficiency and blood stasis-thin endometrium (KDBS-TE) by transcriptome sequencing. MethodThe rat model of KDBS-TE was established by administration of tripterygium polyglycosides tablets combined with subcutaneous injection of adrenaline. The pathological changes of rat endometrium in each group were then observed. Three uterine tissue specimens from each of the blank group, model group, and Bushen Huoxue enema group were randomly selected for transcriptome sequencing. The differentially expressed circRNAs, lncRNAs, and miRNAs were screened, and the disease-related specific competitive endogenous RNA (ceRNA) regulatory network was constructed. Furthermore, the gene ontology (GO) functional annotation and the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment were performed for the mRNAs in the network. ResultCompared with the blank group, the model group showed endometrial dysplasia, decreased endometrial thickness and endometrial/total uterine wall thickness ratio (P<0.01), and differential expression of 18 circRNAs, 410 lncRNAs, and 7 miRNAs. Compared with the model group, the enema and estradiol valerate groups showed improved endometrial morphology and increased endometrial thickness and ratio of endometrial to total uterine wall thickness (P<0.05). In addition, 21 circRNAs, 518 lncRNAs, and 17 miRNAs were differentially expressed in the enema group. The disease-related specific circRNA-miRNA-mRNA regulatory network composed of 629 nodes and 664 edges contained 2 circRNAs, 34 miRNAs, and 593 mRNAs. The lncRNA-miRNA-mRNA regulatory network composed of 180 nodes and 212 edges contained 5 lncRNAs, 10 miRNAs, and 164 mRNAs. The mNRAs were mainly enriched in Hippo signaling pathway, autophagy-animal, axon guidance, etc. ConclusionBushen Huoxue enema can treat KDBS-TE in rats by regulating specific circRNAs, lncRNAs, and miRNAs in the uterus and the ceRNA network.
