Background: Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) represents a prevalent urological disorder characterized by urinary symptoms, persistent pelvic or perineal discomfort accompanied by intraprostatic leukocyte infiltration. The C-X-C chemokine receptor type 4 (CXCR4) is critically involved in mediating inflammatory responses. Nevertheless, the specific involvement of CXCR4 in the immunoinflammatory mechanisms underlying CP/CPPS pathogenesis remains poorly characterized. Methods: The therapeutic efficacy of AMD3100, a CXCR4 antagonist, in CP/CPPS was evaluated in a murine model of experimental autoimmune prostatitis (EAP). The progression of EAP and T helper 17 (Th17) cell-mediated immune responses following AMD3100 intervention was assessed via HE staining, immunohistochemistry, immunofluorescence, quantitative polymerase chain reaction (qPCR), and flow cytometry. To unravel mechanistic insights into the role of CXCR4 in regulating Th17 cell differentiation, RNA sequencing, qPCR, and western blotting validation were conducted. In addition, histological staining, measurements of reactive oxygen species (ROS) and peroxidation markers, and co-culture assays were employed to assess the antioxidative effects of AMD3100 in prostate epithelial cells. Results: AMD3100 significantly alleviated a series of symptoms of prostatitis in EAP mice. Meanwhile, inhibition of CXCR4 by AMD3100 could significantly decrease the proportion of Th17 cells and downregulate the elevated expression of both pro-inflammatory and Th17-associated cytokines in these mice. However, administration of IL-17A partially reversed the therapeutic effects of AMD3100, elevating oxidative stress biomarkers and promoting the apoptosis of prostate epithelial cells. Mechanistically, CXCR4 inhibition suppresses NF-κB activation, thereby inhibiting Th17 cell differentiation. Furthermore, integrated findings from both in vitro and in vivo studies demonstrated that aberrant NF-κB activation not only counteracted AMD3100-mediated suppression of Th17 cell differentiation but also exacerbated prostatic epithelial cell damage through amplified inflammatory responses, oxidative stress, and apoptosis. Conclusions: CXCR4 presents a promising therapeutic target for CP/CPPS. Pharmacological blockade of CXCR4 with AMD3100 inhibits Th17 cell differentiation, consequently mitigating inflammatory infiltration and oxidative tissue injury in CP/CPPS.

OBJECTIVES:Post-traumatic joint contracture (PTJC) is a debilitating fibrotic disorder whose underlying molecular drivers, particularly the involvement of cellular senescence, remain poorly elucidated. This study aimed to evaluate the therapeutic potential of Relaxin-2 (RLX-2) in attenuating knee joint fibrosis and to explore its regulatory effects on the cGAS-STING signaling axis. METHODS:In vitro fibrotic phenotypes were recapitulated using TGF-β1-stimulated rat synovial fibroblasts. An in vivo PTJC model was established via surgical trauma combined with internal fixation-induced immobilization in rats. The anti-fibrotic and anti-senescent properties of RLX-2 were characterized by quantifying markers such as Collagen I, α-SMA, p16, and p53. Transcriptomic profiling via RNA-sequencing was employed to identify potential signaling hubs. The mechanistic involvement of the cGAS-STING pathway was further interrogated using the pharmacological inhibitor H-151 in both experimental settings. RESULTS:In vitro, RLX-2 treatment exerted a concentration-dependent inhibitory effect on TGF-β1-induced fibrogenic transition and cellular senescence. In the rat model, intra-articular administration of RLX-2 resulted in a significant reduction in synovial hyperplasia and extracellular matrix deposition. These phenotypic improvements were associated with the downregulation of senescence markers in the synovium. Mechanistically, RNA-seq analysis pointed toward the cGAS-STING pathway as a primary target of RLX-2. RLX-2 administration was associated with decreased phosphorylation of STING and its downstream effector TBK1. Notably, pharmacological blockade of STING by H-151 partially phenocopied the protective effects of RLX-2, suggesting a coordinated regulation of fibrosis and senescence. CONCLUSION:Our findings demonstrate that RLX-2 attenuates post-traumatic knee joint fibrosis in rats, a process associated with the modulation of the cGAS-STING-senescence axis. These results suggest that targeting the cGAS-STING pathway may represent a viable strategy for managing PTJC, with RLX-2 serving as a promising pharmacological candidate for further clinical investigation.

Adjusting for covariates in randomized controlled trials can enhance the credibility and efficiency of treatment effect estimation. However, handling numerous covariates and their complex (non-linear) transformations poses a challenge. Motivated by the case study of the Best Apnea Interventions for Research (BestAIR) trial data from the National Sleep Research Resource (NSRR), where the number of covariates (p=114) is comparable to the sample size (N=196), we propose a principled Covariate Adjustment with Variable Selection (COADVISE) framework. COADVISE enables variable selection for covariates most relevant to the outcome while accommodating both linear and nonlinear adjustments. This framework ensures consistent estimates with improved efficiency over unadjusted estimators and provides robust variance estimation, even under outcome model misspecification. We demonstrate efficiency gains through theoretical analysis, extensive simulations, and a re-analysis of the BestAIR trial data to compare alternative variable selection strategies, offering cautionary recommendations. A user-friendly R package, Coadvise, is available to facilitate practical implementation.

Chronic prostatitis and chronic pelvic pain syndrome (CP/CPPS) are diagnosed in patients with various pelvic or genitourinary symptoms irrespective of the presence of a tender prostate. The etiology of chronic nonbacterial prostatitis remains unclear. Current treatments such as alpha-blockers, neuroleptics, anti-inflammatory，medications, and physical therapy, are often unsatisfactory. New treatments, as well as an improved knowledge of the underlying CP/CPPS pathogenesis, are thus needed. Sulforaphane (SFN), an isothiocyanate found in large quantities in Brassica species, has shown therapeutic effects on inflammation and cancer, and can protect against DNA damage and modulate the cell cycle to control apoptosis, angiogenesis, and metastasis. At the molecular level, SFN modulates cell homeostasis by activating the transcription factor Nrf2. However, its effect on CP/CPPS is not clear. Here, SFN was found to alleviate inflammation by suppressing NLRP3 inflammasomes via the Nrf2/HO-1 axis, as demonstrated in both animal and cellular analyses.

Background:Chronic prostatitis is a common urological disorder in young and middle-aged men, characterized by frequent relapses and an unknown etiology. We investigated the potential function of insulin-like growth factor 1 (IGF1) -related ligands in chronic prostatitis in the current study. Methods:In this study, we established the chronic experimental autoimmune prostatitis mouse model H&E staining was used to assess immune cell infiltration in prostate tissue, while RT-qPCR and Western blot analyses were performed to validate gene and protein expression differences across groups, respectively. Immunofluorescence staining was utilized to determine the spatial distribution of key proteins. Flow cytometry was conducted to analyze the proportions of immune cell populations in different experimental groups. Adeno-associated virus (AAV) was employed to knock down Igflr, and ELISA was used to measure cytokine levels in the peripheral blood of mice. Statistical significance was defined as P < 0.05, and all tests were conducted as two-tailed. Data analysis was performed using R software (version 4.2.2). Results:We successful established the EAP model and discovered that the expression of IGF1R, content of IGF1-related ligands, was highest in prostate tissue and CD4+ T cell subset. Furthermore, protein expression levels of IGF1R were also validated that upregulated in mouse prostate tissue. Colocalization of immunofluorescence suggested that IGF1R protein is highly expressed on CD4+ T cells. Stimulation with desIGF1, a truncated analogue of IGF1, resulted in the significantly increased prostate inflammation and pain scores observed in the EAP+desIGF1 group mouse compared to other groups In vitro study further suggested that desIGF1 could increase the proportion of Th17 cells while decreasing the proportion of Treg cells. In the EAP+AAV-shIgf1r group, the knock down function of igf1r led to the alleviative prostate inflammation and response frequency of pain behavior test. We found that calcium ion associated pathways are active in EAP by bioinformatics, and further validated that PKC-β protein with significantly increased expression noted in the EAP+desIGF1 group, and decreased in the EAP+AAV-shIgf1r group. We also found that the proportion of Th17 cells increased after activation of PKC- β by flow cytometry. Conclusion:These findings support that PKC-β associated pathways mediated by IGF1/IGF1R axis may impact Th17 cell differentiation and exacerbating prostate inflammation in EAP mouse, providing new molecular targets for the clinical therapeutic strategy.

BACKGROUND:Cold atmospheric plasma (CAP) has been shown to improve the recovery of transected peripheral nerves. We determined the protective role of CAP-activated saline (CAP-AS) treatment in the acute and subacute stages of spinal cord injury (SCI) in mice. METHODS:C57BL/6 SCI mice were treated with CAP-AS for 14 days. Injury recovery was assessed weekly for four weeks by conducting motor function tests, including the Basso Mouse Scale (BMS) and footprint test. Transcriptome analysis was conducted on day 14 to elucidate potential mechanisms, which were further validated through immunofluorescence examinations of the injured spinal cord tissues on day 28 and the levels of proinflammatory cytokines produced by macrophages in vitro. RESULTS:Compared to the SCI group, the CAP-AS-treated groups presented significantly better hindlimb motor function after four weeks. The downregulated (SCI vs. SCI + CAP-AS, with CAP-AS activated for 20 min) differentially expressed genes (DEGs) were enriched in the extracellular region, extracellular matrix (ECM), and ECM-receptor interaction. In contrast, the upregulated DEGs were enriched in immune response-associated pathways. Histological changes in the CAP-AS-treated groups were observed to further validate the predicted mechanisms 28 days post-injury. The alleviation of secondary injury was confirmed by an increase in GFAP-positive and NFH-positive areas, and enhanced outgrowth of 5-HT-positive fibers. Inhibited ECM remodeling was confirmed by a decrease in the areas positive for PDGFRβ, fibronectin, and laminin. A decrease in the infiltration of macrophages and activation of microglia was determined by a decrease in CD68-positive and F4/80-positive areas. The inhibitory effect of CAP-AS on inflammation was further supported by a decrease in the levels of the proinflammatory cytokines IL-1β, IL-6, and TNF-α in CAP-AS-treated M1 macrophages. CONCLUSION:CAP-AS can alleviate secondary injury in SCI model mice by inhibiting ECM remodeling in injured tissues and reducing the infiltration or activation of proinflammatory macrophages/microglia.

Pulmonary hypertension (PH) is a vascular disease characterized by remodeling of the pulmonary arteries and right heart failure. Chronic obstructive pulmonary disease (COPD) patients often have PH, which can worsen symptoms and raise morbidity and mortality. There are several reasons for increased pulmonary vascular resistance, pulmonary vascular remodeling, and ultimately the development of PH in COPD. These factors include genetics, inflammation caused by chemicals breathed, and changes in the alveoli seen in COPD and its physiology. Genes involved in mRNA conversion, subcellular localization, splicing, and translation are all finely tuned by RBPs in their post-transcriptional regulation. Erythropoietin regulates cytokines, chemokines, proteins, growth factors, and other pro-inflammatory mediators that change the lung microenvironment. Over the past few years, we have learned more about how RBPs act in PH and COPD. Here, we discuss the existing understanding of RBPs' location in the same pathogenic pathways shared by PH and COPD in order to emphasize their potential relevance as disease determinant/biomarker and, consequently, for possible therapeutic targeting.

Chronic prostatitis is one of the most common urologic diseases that troubles young men, with unclear etiology and ineffective treatment approach. Pyroptosis is a novel model of cell death, and its roles in chronic prostatitis are unknown. In this study, P2X7R, NEK7, and GSDMD-NT expression levels were detected in prostate tissues from benign prostate hyperplasia (BPH) patients and experiment autoimmune prostatitis (EAP) mice. P2X7R agonist, antagonist, NLRP3 inhibitor, and disulfiram were used to explore the roles of the P2X7R-NEK7-NLRP3 axis in prostate epithelial cell pyroptosis and chronic prostatitis development. We found that P2X7R, NEK7, and GSDMD-NT were highly expressed in the prostate epithelial cells of BPH patients with prostatic inflammation and EAP mice. Activation of P2X7R exacerbated prostatic inflammation and increased NLRP3 inflammasome component expressions and T helper 17 (Th17) cell proportion. Moreover, P2X7R-mediated potassium efflux promoted NEK7-NLRP3 interaction, and NLRP3 assembly and activation, which caused GSDMD-NT-mediated prostate epithelial cell pyroptosis to exacerbate EAP development. Disulfiram could effectively improve EAP by inhibiting GSDMD-NT-mediated prostate epithelial cell pyroptosis. In conclusion, the P2X7R-NEK7-NLRP3 axis could promote GSDMD-NT-mediated prostate epithelial cell pyroptosis and chronic prostatitis development, and disulfiram may be an effective drug to treat chronic prostatitis.

BACKGROUND:Depression is a common mental disease, accompanied by anxiety and persistent depression. Endophilin A1 (EPA1) is a brain-specific protein enriched in synaptic terminals that is primarily expressed in the central nervous system. It has been reported that EPA1 is involved in neurotransmitter release, which indicates that the protein may be involved in depression. However, it is unclear whether EPA1 is implicated in the development of depression.METHODS:The mice depression model was established by chronic unpredicted mild stress (CUMS). Depression-like behaviors were detected by sucrose preference test (SPT), forced swim test (FST), tail-suspension test (TST) and open-field test (OFT). Neuronal histopathology was applied by hematoxylin and eosin stain (H&E), and Nissl stain. EPA1, NLRP1 inflammatory complexes, NADPH oxidase2 (NOX2), synaptic-related protein expression of the mice were tested by western blot. Immunofluorescence was applied to detect the expression of EPA1 and ROS in mice hippocampus. EPA1 knockdown was performed by an adeno-associated virus (AAV) vector containing EPA1-shRNA-EGFP infusion.RESULT:CUMS exposure induced depressive-like behaviors and increased the expression of EPA1 in the hippocampus. Knockdown hippocampal EPA1 ameliorated CUMS-induced depressive-like behaviors, decreased calcium (Ca2+) overload, decreased ROS generation and NOX2 expression, inhibited NLRP1 inflammasome-driven neuroinflammation, and restored the levels of BDNF, PSD95, GAP-43, SYN, and MAP-2 in the hippocampus.CONCLUSION:EPA1 contributes to CUMS induced depressive-like behaviors and the mechanism may be related to NLRP1 inflammasome-driven inflammatory response, regulating calcium ion homeostasis and ROS generation, and alleviating synaptic function damage. This indicated that EPA1 may participate in the occurrence and development of depression.

Methylmercury (MeHg), a potent neurotoxic substance, causes adverse health outcomes by modulating metabolites through altered gut microbiota patterns. Among the many metabolites, neurotransmitters play a particularly important role in the nervous system and behavior. Resveratrol (RSV) has been investigated as an antiaging, antioxidant, anti-inflammatory, and neuroprotective agent. The current study evaluated that RSV is protective of neurodevelopmental toxicity induced by MeHg and further explored the underlying mechanisms. Sprague-Dawley rats were treated with 1.2 mg/kg/d of MeHg, and the effects were evaluated after supplementation with RSV (20 mg/kg/d). The results indicated that MeHg had adverse effects on early neurodevelopmental indicators in the experimental group offspring as compared to control pups. Interestingly, RSV significantly improved the MeHg-induced delays in the neurobehavioral reflexes and reduced the total mercury (THg) concentration in the colons of the offspring rats. In agreement, RSV administration improved the gut microbiota diversity and structure by increasing the abundance of probiotics and upregulating the expression of tight junction proteins. It also ameliorated the MeHg-induced abnormalities in the expression profiles of neurotransmitters. Furthermore, eight key bacteria that were strongly linked with the neurotransmitters and neuroreflex parameters were identified. Taken together, these results demonstrate that RSV treatment effectively reduces the occurrence of neurodevelopmental toxicity caused by perinatal MeHg exposure by modulating the intestinal flora and neurotransmitter metabolism. These findings provide a new therapeutic approach for treating MeHg-induced neurotoxicity.

Purpose With the heterogeneous genetic background, prognosis prediction and therapeutic targets for testicular germ cell tumors (TGCTs) are still unclear. We defined the tumor immune microenvironment activation status (TIMEAS). Methods We collected a total of 314 TGCT patients from four cohorts, including a 48-case microarray. A nonnegative matrix factorization algorithm was applied to identify the “immune factor”, derived the top 150 weighted genes to divide patients into immune and non-immune classes, and further separated the immune class into activated and exhausted subgroups by nearest template prediction. Tumor mutant burden, gene mutation, and copy number alteration were compared with our recently developed package “ MOVICS”. A random forest algorithm was performed to establish a prediction model with fewer genes. Immunohistochemistry staining was performed to identify TIMEAS in the microarray. Results We constructed the TIMEAS in the TCGA-TGCT cohort and further validated it in the GSE3218 and GSE99420 cohorts. The immune class contained the activated status of T-lymphocytes, B-lymphocytes, and macrophages, while Treg cells and the WNT/TGFβ signature were more activated in the immune-suppressed subgroup. Patients in the immune-exhausted subgroup had the worst prognosis, and 22.9% of patients in the immune-activated subgroup had KRAS mutations, which might stimulate the response of the immune system and lead to a favorable prognosis. The immune-exhausted group benefited more from chemotherapy, while the immune-activated subgroup responded well to anti-PD-1/PD-L1 therapy. FSCN1 was validated as the target of the immune-exhausted microenvironment by immunohistochemistry. Conclusion TIMEAS classification can separate TGCT patients; patients in the immune-activated subgroup could benefit more from anti-PD-L1 immunotherapy, and those in the immune-exhausted subgroup are more suitable for chemotherapy.

Litter size is an economically important trait in the swine industry. A high ovulation rate is a prerequisite for a large litter size. It differs among pig breeds with different genetic backgrounds. During the middle-late follicular stage, the medium-sized follicles (3-6.9 mm) of sows with a high ovulation rate can maintain their potential for development into ovulatory follicles. In this study, Meishan and Duroc sows were utilized as model animals due to their extreme litter size phenotypes. M2 follicles (5-6.9 mm) were collected on Day 4 of the follicular phase for high-throughput sequencing of small RNAs and mRNAs. Differentially expressed miRNAs (DEMs) and differentially expressed genes (DEGs) were analyzed. KEGG pathway and GO enrichment analyses were conducted to analyze the DEGs and the target genes of DEMs, resulting in the construction of a regulatory network of DEMsDEGs. A total of 402 miRNAs were identified, with 8 upregulated and 3 downregulated miRNAs in the Meishan group. KEGG pathway analysis revealed significant enrichment of target genes of DEMs in pathway such as Apoptosis, GnRH signaling pathway, MAPK signaling pathway, and PI3K-Akt signaling pathway. GO enrichment analysis revealed 1930 significantly enriched GO terms. KEGG pathway analysis of the DEGs revealed 13 significantly enriched pathways, including those involved in complement and coagulation cascades, ECMreceptor interactions, and PI3K-Akt signaling pathway. A total of 642 GO terms were significantly enriched. Through Pearson correlation analysis, 67 DEM-DEG pairs were identified, and 62 DEGs were found to be regulated by 9 DEMs. This study provides valuable insights into the function of miRNAs and mRNAs in regulating the growth and development of follicles.

BACKGROUND:Endophilin A1 (EPA1) is encoded by the SH3GL2 gene, and SH3GL2 was designated as a Parkinson's disease (PD) risk locus by genome-wide association analysis, suggesting that EPA1 may be involved in the occurrence and development of PD. OBJECTIVE:To investigate the role of EPA1 in lipopolysaccharide (LPS)-induced PD model mice. METHODS:The mice PD model was prepared by injecting LPS into the substantia nigra (SN), and the changes in the behavioral data of mice in each group were observed. The damage of dopaminergic neurons, activation of microglia, and reactive oxygen species (ROS) generation were detected by immunofluorescence method; calcium ion concentration was detected by calcium content detection kit; EPA1 and inflammation and its related indicators were detected by western blot method. EPA1 knockdown was performed by an adeno-associated virus vector containing EPA1-shRNA-eGFP infusion. RESULTS:LPS-induced PD model mice developed behavioral dysfunction, SN dopaminergic nerve damage, significantly increased calcium ion, calpain 1, and ROS production, activated NLRP1 inflammasome and promoted pro-inflammatory cell release, and SN EPA1 knockdown improves behavioral disorders, alleviates dopaminergic neuron damage, reduces calcium, calpain 1, ROS generation, and blocks NLRP1 inflammasome-driven inflammatory responses. CONCLUSION:The expression of EPA1 in the SN of LPS-induced PD model mice was increased, and it played a role in promoting the occurrence and development of PD. EPA1 knockdown inhibited the NLRP1 inflammasome activation, decreased the release of inflammatory factors and ROS generation, and alleviated dopaminergic neuron damage. This indicated that EPA1 may participating in the occurrence and development of PD.

Objective To measure the effects of cerebral intermittent theta-burst stimulation with physiotherapy on lower extremity motor recovery in patients with incomplete spinal cord injury. Design Randomized, double-blinded, sham-controlled trial. Subjects Adults with incomplete spinal cord injury. Methods A total of 38 patients with incomplete spinal cord injury were randomized into either an intermittent theta-burst stimulation or a sham group. Both groups participated in physiotherapy 5 times per week for 9 weeks, and cerebral intermittent theta-burst stimulation or sham intermittent theta-burst stimulation was performed daily, immediately before physiotherapy. The primary outcomes were lower extremity motor score (LEMS), root-mean square (RMS), RMS of the quadriceps femoris muscle, walking speed (WS), and stride length (SL). Secondary outcomes comprised Holden Walking Ability Scale (HWAS) and modified Barthel Index (MBI). The outcomes were assessed before the intervention and 9 weeks after the start of the intervention. Results Nine weeks of cerebral intermittent thetaburst stimulation with physiotherapy intervention resulted in improved recovery of lower extremity motor recovery in patients with incomplete spinal cord injury. Compared with baseline, the changes in LEMS, WS, SL, RMS, HWAS, and MBI were significant in both groups after intervention. The LEMS, WS, SL, RMS, HWAS, and MBI scores were improved more in the intermittent theta-burst stimulation group than in the sham group. Conclusion Cerebral intermittent theta-burst stimulation with physiotherapy promotes lower extremity motor recovery in patients with incomplete spinal cord injury. However, this study included a small sample size and lacked a comparison of the treatment effects of multiple stimulation modes, the further research will be required in the future. LAY ABSTRACT Spinal cord injury is a serious condition caused by spinal trauma and tumours. Improving the patient’s limb function during recovery poses an important challenge. Transcranial magnetic stimulation technology is a new treatment used to improve nervous system function, which has shown promising results in treating spinal cord injuries in recent years. However, the effect of a specific type of magnetic stimulation, cerebral intermittent theta-burst stimulation, with routine physical therapy on lower extremity motor recovery in patients with incomplete spinal cord injury has not yet been explored. The results of this study suggest that 9 weeks of brain intermittent theta-burst stimulation combined with physical therapy has a positive short-term effect on lower extremity movement and recovery of daily living ability in patients with incomplete spinal cord injury, which might provide new insight into motor rehabilitation for spinal cord injury.

Abstract Background and aims Evidence has shown that miR-31 is a molecule associated with inflammation in different types of cells.However,the changes of miR-31 in LPS-stimulated endothelial cells and the effect of this change in expression on endothelial cells are unknown.This study sought to investigate how miR-31 modulates endothelial permeability and inflammation in LPS-stimulated culture pulmonary microvascular endothelial cells (PMVECs). Methods It was discovered that enhanced cell monolayer permeability was defined by lower TER and higher FITC-dextran levels. Cell viability was evaluated using an MTT assay, and inflammatory factor concentration was measured using an ELISA. Western blotting and quantitative real-time PCR were utilized to quantify protein and mRNA expression. Results In LPS-stimulated PMVECs, cell permeability was increased and miR-31 levels were reduced.In PMVECs overexpressed miR-31, the increased cell permeability induced by LPS was significantly improved and the elevated levels of inflammatory factors induced by LPS were reduced. Besides,LPS-induced reductions in PI3K and AKT phosphorylation were restored by overexpressing miR-31. Inhibition of PI3K led to elevated levels of TNF-α, ICAM-1, IL-6, VCAM-1 inflammatory factor, and FITC-dextran and lower levels of TER. MiR-31 negatively controlled ROCK1 expression. The co-expression of ROCK1 and miR-31 caused the downregulation of the phosphorylated PI3K expression and decreased TER and increased FITC-dextran compared with miR-31 overexpression alone. Conclusion In response to LPS, PMVECs downregulate microRNA-31, which has been linked to PMVEC inflammation and permeability through activating the PI3K/AKT signaling cascade via ROCK1.

To identify prostate cancer (PCa) patients with a high risk of recurrence is critical before delivering adjuvant treatment. We developed a classifier based on the Enzalutamide treatment resistance-related genes to assist the currently available staging system in predicting the recurrence-free survival (RFS) prognosis of PCa patients. We overlapped the DEGs from two datasets to obtain a more convincing Enzalutamide-resistance-related-gene (ERRG) cluster. The five-ERRG-based classifier obtained good predictive values in both the training and validation cohorts. The classifier precisely predicted RFS of patients in four cohorts, independent of patient age, pathological tumour stage, Gleason score and PSA levels. The classifier and the clinicopathological factors were combined to construct a nomogram, which had an increased predictive accuracy than that of each variable alone. Besides, we also compared the differences between high- and low-risk subgroups and found their differences were enriched in cancer progression-related pathways. The five-ERRG-based classifier is a practical and reliable predictor, which adds value to the existing staging system for predicting the RFS prognosis of PCa after radical prostatectomy, enabling physicians to make more informed treatment decisions concerning adjuvant therapy.

To investigate the mechanism of Dragon’s Blood, a Chinese herbal medicine, in the treatment of diabetic kidney disease (DKD) by Bioinformatics analysis. Literature searches and database screening were carried out to identify the main active ingredients of Dragon’s blood; the SwissTargetPrediction database was used to predict the active ingredients.. Cytoscape 3.7.2 software and the STRING platform was used to construct a medicine-compounds-disease-targets PPI (Protein–Protein Interaction Networks) network of potential targets. The DAVID database was used to perform GO enrichment and KEGG signal pathway analysis. Finally, Autodock vina was used for docking simulations and Pymol was used to visualize interactions between ligands and proteins. We found that Dragon’s blood can play a preventive and therapeutic effect on AKT1, IL6, TNF, VEGFA, TP53, SRC, through the PI3K-Akt, HIF-1, and FoxO signaling pathways.
