RESUMO
OBJECTIVE: To investigate the expression and significance of GDF3 in testicular cancer through bioinformatics analysis. METHODS: Using the TCGA and GTEx databases, differential expression analysis and pan-cancer analysis were performed to identify the target gene GDF3, and the clinical relevance of GDF3 in testicular cancer was analyzed using the UALCAN database. Based on the R packages "org.Hs.eg.db" and "clusterProfiler," gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were conducted to explore the potential functions of GDF3 in testicular cancer. The correlation of GDF3 with immune chemokines and immune inhibitors in testicular cancer was investigated using the TISIDB database. RESULTS: The GDF3 was significantly upregulated in testicular cancer (P<0.001) and closely associated with clinical staging (P<0.05) and tumor subtypes (P<0.001). The immune-related analysis revealed that GDF3 was strongly correlated with immune chemokines CCL26 (rho=0.599, P<0.001), CCL7 (rho=0.525, P<0.001), immune inhibitor ADORA2A (rho=0.723, P<0.001), and PVRL2 (rho=0.585, P<0.001). CONCLUSION: The GDF3 is closely related to the occurrence, development, and immune microenvironment of testicular cancer.

OBJECTIVE: To investigate the biological mechanisms underlying the effect of the Chinese herbal medicine Oxalis corniculata on human prostate cancer PC-3 cells. METHODS: Through in vitro experiment, we treated human prostate cancer PC-3 cells with different concentrations of Oxalis corniculata, assessed the viability of the cells by MTT assay, examined their apoptosis by flow cytometry, evaluated their migration and invasiveness by Transwell assay, and determined the expressions of the proteins p65, p-p65, IκBα and p-IκBα in the NF-κB pathway using protein imprinting technology. RESULTS: Compared with the blank control, Oxalis corniculata significantly inhibited the proliferation and induced the apoptosis of the PC-3 cells (P< 0.05), suppressed their migration and invasiveness in a dose-dependent manner (P< 0.05), and upregulated the expression of IκBα and downregulated those of p-p65 and p-IκBα in the NF-κB pathway (P< 0.05). CONCLUSION: Oxalis corniculata can inhibit the proliferation, migration and invasiveness and induce the apoptosis of human prostate cancer PC cells, which may be attributed to its abilities of inhibiting the expressions of p-p65 and p-IκBα and regulating the activity of the NF-κB pathway.

OBJECTIVE: To investigate the correlation of serum and seminal plasma homocysteine (Hcy) levels with semen parameters in men and its effect on recurrent spontaneous abortion (RSA) in their spouses. METHODS: The study included 103 males subjects undergoing preconception examination in the reproduction center from March 2022 to June 2023. According to whether their spouses had a history of RSA or not, we divided their subjects into an RSA (n = 43) and a non-RSA group (NRSA, n = 60), obtained their serum and seminal plasma Hcy levels and semen parameters, and analyzed their correlation. RESULTS: The serum Hcy level was significantly correlated with the sperm DNA fragmentation index (DFI) (r = 0.316, P = 0.005), but not with the seminal plasma Hcy level (r = ï¼0.041, P = 0.723) and other semen parameters of the subjects (P > 0.05). There was no significant correlation between seminal plasma Hcy and semen parameters (P > 0.05). The median serum Hcy was significantly higher in the RSA than in the NRSA group (18.39 ï¼»13.02, 42.84ï¼½ vs 14.65 ï¼»12.00, 18.20ï¼½ µmol/L), with statistically significant difference in the overall distribution of serum Hcy between the two groups (Z=ï¼2.20, P = 0.028), so was the median sperm DFI in the former than in the latter group (25.00% ï¼»12.50%, 37.25%ï¼½ vs 13.00% ï¼»11.00%, 18.50%ï¼½), with statistically significant difference in the overall sperm DFI distribution between the two groups (Z=ï¼2.74, P = 0.006). CONCLUSION: The serum Hcy level was positively correlated with sperm DFI, and both serum Hcy and sperm DFI were significantly elevated in men with spousal RSA, which is expected to be used as a clinical screening indicator for males with spousal RSA.

OBJECTIVE: To explore the potential action mechanisms of Xiaoluowan (II) (XLW-II) in the treatment of epididymitis through a network pharmacology approach. METHODS: We searched various databases for relevant targets associated with epididymitis and XLW-II and obtained the common targets of epididymitis and XLW-II on the Venny platform. We acquired the protein-protein interactions (PPI) using the STRING data and had them visualized with the Cytoscape software. After topological analysis, we retrieved the key targets, followed by gene ontology (GO) and KEGG pathway enrichment analyses using the DAVID database. RESULTS: A total of 2 38 drug targets, 2 150 disease targets and 85 common targets were identified. The core targets for the treatment of epididymitis with XLW-II identified by PPI network analysis included TNF, IL6, IL1B, MMP9, AKT1, PTGS2 and TP53. GO function analysis revealed the involvement of the common targets in such biological processes as response to hypoxia, regulation of apoptotic processes, inflammatory response, and positive regulation of the MAPK cascade. KEGG pathway analysis suggested that the signaling pathways such as the cancer pathway, PI3K-Akt pathway, protein glycosylation pathway in cancer, Ras pathway and chemokine pathway might be related to the action mechanisms of XLW-II in the treatment of epididymitis. CONCLUSION: The potential targets and signaling pathways of Xiaoluowan (II) in the treatment of epididymitis were identified on the basis of network pharmacology, which has provided a novel insight into its action mechanisms and offered a new direction for further relevant studies.

Objectiveï¼ To explore the mechanism of Miao ethnicity medicine formula of Oxalis corniculata against chronic non-bacterial prostatitis. Methods: The rat model of chronic abacterial prostatitis was induced by stimulation with 2% sterile carrageenan solution. After modeling, the rats were randomly divided into two groups, Model control group (Model group) and oxalis group. Another normal control group was set up. The rats in the Model group and the normal control group were given 0.01ml/g normal saline by gavage, and the rats in the oxalis alis group were given 1ml/100g (1 g/kg) of Oxalis corniculata L warm water decoction by gavage once a day for 28 days. Twenty-four hours after the last administration, 10ml blood was collected from the abdominal aorta of the rats, and prostate tissue samples were collected from the rats. hematoxylin-eosin (HE) staining was used to observe the morphological structure of the prostate in normal and prostatitis rats. ELISA was used to detect the levels of serum and prostate cytokines. The protein expressions of 4-HNE , ALDH2 and FGF2 were detected by Western blot. Results: Compared with the blank group, the model group showed obvious hyperplasia of fibrous tissue in the interstitium of the prostate tissue, disordered glandular structure, papillary hyperplasia of epithelial cells in the acini, infiltration of a small amount of lymphocytes, monocytes and other inflammatory cells in the acini, and increased pathological scores. The protein expressions of 4-HNE , ALDH2 , MCP-1 and FGF2 in prostate tissue were significantly increased. Compared with the model group, the prostate tissue of the oxalis group was slightly damaged, with a small amount of fibrous hyperplasia and inflammatory cell infiltration. The protein expressions of 4-HNE , ALDH2 , MCP-1 and FGF2 were decreased in prostate tissue. Conclusionï¼ Oxalis corniculata L can effectively repair the pathological morphology of prostate tissue in rats with CNP, and its mechanism may be related to activating 4-HNE protein and reducing oxidative stress injury of prostate tissue in rats.

OBJECTIVE: To investigate the therapeutic mechanism of oxalis decoction on CNP rats by regulating cGAS-STING signaling pathway. METHODS: Thirty specific pathogen-free SD male rats were randomly divided into normal control group (NC), model control group (MC), and oxalis decoction group (OD),with 10 rats in each group.The left and right anterior abdominal lobes of each group were surgically exposed.The normal control group was injected by the same volume of normal saline.After the model was successfully established,the OD group was given ï¼»9.37g/(kg·d)ï¼½ by gavage once a day, and the NC and MC groups were given ï¼»0.01/(mï½/g)ï¼½ normal saline by gavage. From the 7th day of administration, the body weight of the rats in each group was recorded every 7 days for dynamic comparison. After 50 days of administration, the prostate index of the rats in each group was calculated, the morphological and pathological changes of the prostate tissue were observed by HE staining,and the expression levels of tumor necrosis factorα(TNF-α), interleukin-1ß(IL-1ß)and IL-6 in serum were detected by ELISA. RT-qPCR was used to detect the mRNA expression of cGAS, STING, TRAF6 and HSP70 in prostate tissue of rats in each group. RESULTS: Versus the NC group and OD group, the prostate organ index in MC group was significantly higher than that in other groups (P<0.01). Versus the NC group, the HE staining results of the MC group showed that the prostate gland structure was disordered, and the interstitial and acinar epithelium were extensively edema, accompanied by a large number of lymphocyte infiltration, cell swelling, loose cytoplasm, and a small number of foam cells. Versus the MC group, HE staining showed that the edema of interstitial and acinar epithelial cells in the rat prostate tissue was reduced after the OD group intervention, and the inflammatory cell infiltration in the interstitium was significantly reduced.Versus to NC group, the expression levels of TNF-α,IL-1ßandIL-6 in MC group were significantly increasedï¼P<0.01 ).Versus to MC group,the expression levels of TNF-α, IL-1ß and IL-6 in OD group were decreased (P<0.05). Versus the NC group, the mRNA expression of cGAS, STING and TRAF6 in the MC group was significantly up-regulated,and HSP70mRNA was significantly down-regulated(P<0.01).Versus the MC group,the OD group had significantly decreased mRNA expression of cGAS, STING and TRAF6 and significantly increased mrna expression of HSP70(P<0.05). CONCLUSIONS: CNP has autoimmune disorders that cause inflammatory responses.The key target for CNP treatment is to regulate innate immunity.The treatment with oxalis decoction can significantly improve the prostate organ index and pathological changes in CNP rats, which may be related to the down-regulation of cGAS-STING innate immune signaling pathway and the inhibition of inflammatory mediators secretion.

OBJECTIVE: To explore the potential mechanism of action of levocarnitine in the treatment of epididymitis based on network pharmacology and experimental research. METHODS: The target proteins related to epididymitis and levocarnitine were retrieved through multiple databases, and the common targets were obtained using Venny software. The protein-protein interactions were obtained using the STRING database. Cytoscape software was used for visualization, and key targets were selected after topological analysis. GO and KEGG pathway enrichment analysis was performed using the DAVID database. Molecular docking was performed using Autodock Vina. RESULTS: A total of 130 drug targets and 2 151 disease targets were obtained, with 47 common targets. Protein-protein interaction network analysis identified core targets of levocarnitine in the treatment of epididymitis, including AKT1, HSP90AA1, ALB, CASP3, GSK3B, and GSR. KEGG pathway analysis suggested that metabolic pathways, lipid metabolism and atherosclerosis, cancer pathways, fluid shear stress and atherosclerosis, measles, chemical carcinogens-reactive oxygen species, purine metabolism, PI3K-Akt, and other signaling pathways may be associated with the mechanism of levocarnitine in the treatment of epididymitis. CONCLUSION: This study revealed through network pharmacology that levocarnitine may act on multiple signaling pathways by targeting AKT1, HSP90AA1, ALB, CASP3, GSK3B, GSR, etc., thereby potentially exerting therapeutic effects on epididymitis.

OBJECTIVE: This study aimed to investigate the mechanism of Xiaoluanwan(II) in treating lipopolysaccharide(LPS)-induced epididymitis and its impact on the NLRP3 inflammasome. METHODS: The murine epididymitis model was established through local injection of LPS. The study included a control group (n=5), a model group (n=5), a model group treated with Xiaoluanwan(II) (â ¡) (n=5), and a saline group treated with Xiaoluanwan(II) (n=5). After 14 consecutive days of oral administration of Xiaoluanwan(II) or physiological saline, pathological changes in the epididymal tissues, expression levels of NLRP3 inflammasome and Caspase-1, as well as associated protein levels were examined. RESULTS: Compared to the model group, Xiaoluanwan(II) significantly alleviated inflammatory cell infiltration and lesions, as evidenced by a reduction in the protein expression levels of NLRP3, Caspase-1, Cleaved-Caspase-1, IL-1ß, IL-18, GSDMD, and p-p38 MAPK (P<0.05 or P<0.01), thereby mitigating the inflammatory response. CONCLUSION: Xiaoluanwan(II) alleviates epididymal inflammation and ameliorates mouse epididymal epithelial injury by modulating the NLRP3-mediated cell pyroptosis pathway.
