ObjectiveTo observe the mechanism of Guihuang formula in regulating the activation of NOD-like receptor protein 3 (NLRP3) inflammasome and inhibiting pyroptosis in the treatment of type Ⅲ prostatitis. Methods(1) In an animal experiment, 50 Sprague Dawley (SD) rats were randomly divided into a blank group, a model group, and low-dose, medium-dose, and high-dose groups of Guihuang formula, with 10 rats in each group. Except for the blank group, the type Ⅲ prostatitis rat model was prepared for the other four groups.After the modeling was successful, the blank group and the model group were given normal saline intragastrically, and the low-dose, medium-dose, and high-dose groups of Guihuang formula were given intragastrically with Guihuang formula (4.9, 9.8, 19.6 g·kg-1). After 30 days of intragastrical administration, samples were taken for detection. Inflammatory cell infiltration in prostate tissue was observed by hematoxylin-eosin (HE) staining, and serum IL-1β and IL-18 levels were measured by enzyme-linked immunosorbent assay (ELISA). Serum malondialdehyde (MDA), superoxide dismutase (SOD), and glutathione peroxidase (GSH-Px) levels were determined by biochemistry. NLRP3 expression in prostate tissue was assessed by immunohistochemistry, and the expression of NLRP3, cysteine-aspartic acid protease-1 (Caspase-1), and gasdermin D (GSDMD) in prostate tissue was measured by Western blot. (2) In a cell experiment, human normal prostate epithelial cells (RWPE-1 cells) were divided into a blank group, a model group, a Guihuang formula group, and an NLRP3 inhibitor group (MCC950 group). Except for the blank group, the other three groups were stimulated by 100 μg·L-1 lipopolysaccharide (LPS) for 4 h and 5 mol·L-1 adenosine triphosphate (ATP) for 30 min to prepare the pyroptosis model. After successful modeling, blank serum was given to the blank group and the model group. 6.25 μg·mL-1 Guihuang formula drug-containing serum was added to the Guihuang formula group, and MCC950 was added to the MCC950 group on the basis of the model group. Propidium iodide (PI) uptake and Caspase-1 expression were detected by flow cytometry, and lactate dehydrogenase (LDH) level in the cell supernatant was measured by biochemistry. Interleukin (IL)-1β and IL-18 levels of the cell supernatant were determined by ELISA, and the expression of NLRP3, Caspase-1, and GSDMD was detected in Western blot. Results(1) For the animal experiment, compared with the blank group, the model group showed significant infiltration of inflammatory cells in prostate tissue, while the low-dose, medium-dose, and high-dose groups of Guihuang formula showed reduced infiltration of acinar inflammatory cells, reduced degree of glandular epithelial degeneration and interstitial edema, and significantly reduced degree of damage. Compared with those in the blank group, the levels of IL-1β and IL-18 in the serum of the model group were significantly increased (P<0.01). Compared with the model group, the low-dose, medium-dose, and high-dose groups of Guihuang formula showed a significant decrease in serum IL-1β and IL-18 levels (P<0.01). Compared with that in the blank group, the serum MDA level in the model group significantly increased (P<0.01). Compared with that in the model group, the MDA level in the low-dose, medium-dose, and high-dose groups of Guihuang formula was significantly reduced (P<0.01). Compared with those in the blank group, the levels of SOD and GSH-Px in the serum of the model group significantly decreased (P<0.05). Compared with the model group, the low-dose, medium-dose, and high-dose groups of Guihuang formula showed a significantly increase in SOD (P<0.01). Compared with the model group, the low-dose, medium-dose, and high-dose groups of Guihuang formula showed a significantly increase in GSH-Px (P<0.05). Immunohistochemistry showed that compared with the blank group, the model group had high expression of NLRP3 molecule in prostate tissue. The expression of NLRP3 in the low-dose, medium-dose, and high-dose groups of Guihuang formula was significantly lower than that in the model group. Compared with those in the blank group, the expression levels of NLRP3, Caspase-1, and GSDMD proteins in the prostate tissue of the model group were significantly increased (P<0.01). Compared with those in the model group, the expression levels of NLRP3, Caspase-1, and GSDMD proteins in the low-dose, medium-dose, and high-dose groups of Guihuang formula were significantly inhibited (P<0.01). (2) For the cell experiment, compared with that in the blank group, the PI uptake rate of RWPE-1 cells in the model group significantly increased (P<0.01). Compared with that in the model group, the PI uptake rate of the Guihuang formula group and the inhibitor group significantly decreased (P<0.01). Compared with that in the blank group, the expression of Caspase-1 in the model group was significantly higher (P<0.01). Compared with that in the model group, the Caspase-1 in the Guihuang formula group and the inhibitor group significantly decreased (P<0.01). Compared with the blank group, the model group showed an increase in LDH release (P<0.01). Compared with the model group, the Guihuang formula group and the inhibitor group showed a significantly decrease in LDH release (P<0.01). Compared with those in the blank group, the levels of IL-1β and IL-18 in the supernatant of the model group were significantly increased (P<0.01). Compared with the model group, the Guihuang formula group and the inhibitor group showed a significantly decrease in the levels of IL-1β and IL-18 (P<0.01). Compared with those in the blank group, the expression levels of NLRP3, Caspase-1, and GSDMD proteins significantly increased in the model group (P<0.01). Compared with those in the model group, the protein expression levels of NLRP3, Caspase-1, and GSDMD were significantly reduced in the Guihuang formula group and inhibitor group (P<0.01). ConclusionGuihuang formula can inhibit the activation of Caspase-1, prevent GSDMD cleavation and lysis, and inhibit cell pyrodeath in the treatment of type Ⅲ prostatitis by inhibiting the activation of NLRP3 inflammasome.

OBJECTIVE To investigate the effect and potential mechanism of toosendanin in enhancing the antileukemic activity of cytosine arabinoside against acute myeloid leukemia (AML) based on the mammalian target of rapamycin complex 1 (mTORC1) signaling pathway.METHODS Female NSG immunodeficient mice were used to establish an AML model via a single γ-ray irradiation followed by a single tail-vein injection of a U937 cell suspension. The effects of cytosine arabinoside (2.5 mg/kg), toosendanin (1.0 mg/kg), and cytosine arabinoside+toosendanin (2.5 mg/kg+1.0 mg/kg) on body weight, survival time, peripheral blood routine indicators, histopathological morphology, and the expressions of autophagy-related proteins were explored. Using U937 cells as the subject, the effects of cytosine arabinoside (1 μmol/L), toosendanin (160 nmol/L), and cytosine arabinoside+toosendanin (1 μmol/L+160 nmol/L) on the expressions of autophagy-related proteins, mTORC1 signaling pathway-related proteins and mRNAs were investigated. The targeting relationship between toosendanin and the selective autophagy ligand 1 (also known as p62) was validated, and the Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses, as well as molecular docking, were performed. A p62 -knockdown U937 stable cell line was constructed, and the underlying mechanism of toosendanin-induced sensitization was verified.RESULTS Animal experiments confirmed that the combination of toosendanin and cytosine arabinoside significantly improved body weight, survival time and peripheral blood routine indicators in AML mice ( P <0.05), alleviated pathological changes such as leukemic cell infiltration and focal necrosis in bone marrow, liver, and spleen tissues, and modulated the expressions of autophagy-related proteins. Cell experiments confirmed that toosendanin could reverse cytosine arabinoside-induced activation of the autophagy cascade (manifested by downregulation of the protein expressions of microtubule-associated protein 1 light chain 3B and Beclin-1, upregulation the protein expression of p62), and might inhibit the expression of the downstream Unc-51-like autophagy activating kinase 1 (ULK1) complex (including ULK1, ULK2, autophagy-related protein 13, and FAK family interacting protein of 200 kDa) by activating the mTORC1 signaling pathway ( P <0.05). The sensitizing effect of toosendanin was associated with the inhibition of autophagy and the regulation of the mTORC1 signaling pathway; it could stably bind to p62 via hydrophobic interactions. Mechanism verification experiments indicated that upon p62 knockdown, toosendanin was no longer able to activate the mTORC1 signaling pathway or inhibit autophagy.CONCLUSIONS Toosendanin may enhance chemo-sensitivity of AML cells to cytosine arabinoside by directly targeting the p62 protein, which subsequently activates the mTORC1 signaling pathway, and thereby suppresses cytosine arabinoside-induced protective autophagy.

Coronary heart disease (CHD) has a distinct circadian rhythmicity in its onset, which is closely related to the waxing and waning of qi and blood in the channel passages of the human body. Grounded in the circadian rhythm theory of "correspondence between heaven and humankind", this paper explores the pathogenic evolution rules of qi-blood disharmony, channel obstruction, interacting as cause and effect with circadian rhythm disorders in CHD. Clinically, CHD can be observed to attack in the early morning, at night, in the afternoon, and at fixed or unfixed circadian intervals. The pathogenesis rhythms at different time nodes can correspondingly reflect the susceptibility tendencies and pathological stress responses of the human body to core pathogeneses such as yang deficiency with cold congelation, yin deficiency with yang floating, qi and yin deficiency, and liver constraint with qi stagnation under specific temporal states. Treatment should be adapted to the season and time, regulating yin and yang in accordance with biological rhythms. It is recommended to regulate qi during the daytime by promoting ascending and dispersing to unblock the channel passages, and select the appropriate timing for administration to harness natural timing. At the Mao (卯) hour, yang ascends while yin descends, and taking medication at this time conforms to the ascending of yang qi. At the Wu (午) hour, the heart meridian is active, and taking medication at this time warms the channel passages and assists heart yang, which can be treated with modified Buzhong Yiqi Decoction (补中益气汤) or Shengyang Yiwei Decoction (升阳益胃汤). At night, blood should be harmonized, when the channel passages are unblocked through nourishing, restraining, and searching, with Lianmei Decoction (连梅汤) combined with Dahuang Zhechong Pill (大黄䗪虫丸). Following the temporal rhythm, the focus is put on the transitional time of day and night and the four seasons to treat disease before it arises, resonating and corresponding with the natural rhythm.

ObjectiveTo investigate the mRNA expression profile and clinical significance of the RAB24 gene in hepatocellular carcinoma (HCC) based on multi-source database including The Cancer Genome Atlas (TCGA) and clinical cohort validation. MethodsData from TCGA (n=424) were utilized to evaluate the prognostic value of RAB24 expression via Kaplan-Meier analysis and Cox regression models. An independent clinical cohort comprising 90 HCC and 30 paracancerous tissues was established to validate protein expression and histopathological features through immunohistochemistry (IHC) and routine histological staining. The TIMER database was employed to analyze the association between RAB24 and the tumor microenvironment (TME). Furthermore, integrated with LinkedOmics, GSEA and GSVA algorithms were used to quantitatively characterize the core molecular pathways regulated by RAB24. ResultsThe mRNA expression level of RAB24 in HCC was significantly higher than that in non-tumor liver tissues (P<0.05). Kaplan-Meier analysis revealed that the overall survival (OS) of patients in the RAB24 low-expression group was significantly longer compared to the high-expression group (HR=1.570, Log-rank P=0.01). Cox proportional hazards regression analysis demonstrated that RAB24 expression (HR=1.480, P=0.028), T stage (HR=2.949, P<0.001), M stage (HR=4.077, P=0.017), and tumor residual status (HR=2.317, P<0.001) were independent prognostic factors for HCC. RAB24 expression was highly correlated with alpha-fetoprotein (AFP) levels and immune infiltration levels (P<0.01), and showed a significant, low-level positive correlation with the TP53 gene (Rho=0.31, P<0.01). Quantitative analysis of the RAB24 protein in clinical samples validated that RAB24 expression in HCC tissues was significantly elevated compared to non-tumor liver tissues (P<0.05). TIMER analysis confirmed that RAB24 expression was highly associated with the infiltration of multiple immune cells (such as B cells and NK cells), as well as stromal and tumor purity scores in tumor tissues (P<0.01). GSEA/GSVA enrichment revealed that the P53, MYC, and mTORC1 signaling pathways were activated in the RAB24 high-expression group; correlation analysis confirmed that the RAB24 expression level exhibited a significant, low-level positive correlation with the ribosome pathway activity score (r=0.23, P<0.01). ConclusionsThe RAB24 gene, as a poor prognostic factor for HCC patients, is a potential biomarker for HCC diagnosis, treatment and prognosis. The study is expected to lay a theoretical foundation for the precise diagnosis and treatment of clinical HCC.

Objective To analyze the PLCβ4 gene mRNA expression and its clinical significance in hepatocellular carcinoma (HCC) based on TCGA database. Methods Based on the data on 424 clinical samples (including 374 cases of HCC tissues and 50 cases of nontumor liver tissues) in the TCGA database, Kaplan–Meier method, Cox regression analysis, and immune infiltration analysis were performed to evaluate the relationship between PLCβ4 gene and the clinical characteristics and survival prognosis of HCC patients. Correlation analysis between PLCβ4 gene and 24 types of immune cells was applied to investigate the relationship between PLCβ4 gene and immune cell infiltration and mRNA expression level of TP53 gene, a high-frequency mutation gene in HCC. In addition, paraffin sections of highly, moderately, and poorly differentiated tumor tissues and normal liver tissues from HCC patients were collected. The histopathological observation was carried out via HE staining method, and the expression levels of PLCβ4 and Ki-67 proteins in each clinical sample were verified through the immunohistochemical method. Results The expression level of PLCβ4 gene in HCC was significantly higher than that in normal tissues (P<0.01), and all patients in the PLCβ4 high-expression group had a significantly longer overall survival than those in the low-expression group (P<0.05), which suggested that PLCβ4 substantially affected the prognosis of HCC patients. Correlation analysis showed that the expression level of PLCβ4 gene was highly correlated with immune cell infiltration and the expression level of TP53 gene. As verified by clinical sample experiments, HE staining experiments and immunohistochemical results revealed that PLCβ4 gene expression in HCC tissue samples was significantly higher than that in normal tissues (P<0.001), and it was negatively correlated with the degree of differentiation. Conclusion PLCβ4 may serve as an independent prognostic factor in HCC and is expected to be a novel molecular target for HCC treatment.

Objective: To identify biomolecular markers closely related to the occurrence of kidney renal clear cell carcinoma (KIRC) and verify their expression levels in clinical samples. Methods: Stage Ⅰ KIRC mRNA sequencing data were obtained from The Cancer Genome Atlas (TCGA).Principal component analysis (PCA) was used for dimensionality reduction to screen differentially expressed genes (DEGs),which then underwent GO and KEGG analyses.Weighted gene co-expression network analysis (WGCNA) was used to screen genes significantly related to KIRC,and a protein-protein interaction (PPI) network was constructed to screen hub genes.The diagnostic value of hub genes was evaluated with receiver operating characteristic (ROC) curve,and their prognostic value was analyzed using survival curve plots.The correlation between the mRNA expressions of hub genes and the pathological stages of KIRC was analyzed.Clinical samples of 20 patients with stage Ⅰ KIRC treated in our hospital were included,and the expressions of the hub genes in cancerous and adjacent tissues were detected with reverse transcription real-time quantitative polymerase chain reaction (RT-qPCR),Western blotting,and enzyme-linked immunosorbent assay (ELISA). Results: A total of 8223 DEGs were screened out,including 4092 up-regulated ones and 4131 down-regulated ones.GO analysis showed that DEGs were related to bioadhesion,plasma membrane composition,and transporter activity.KEGG analysis showed that DEGs were related to pathways such as cell adhesion molecules,cytokine-cytokine receptor interactions,and interactions between viral proteins and cytokines and cytokine receptors.WGCNA analysis obtained 171 genes that were significantly related to stage Ⅰ KIRC.The hub gene,lymphocyte cytosolic protein 2 (LCP2),screened out by the PPI network,was significantly related to stage Ⅰ KIRC.The area under the ROC curve was 0.96.The expression level was negatively correlated with the overall survival rate of patients.The expression of LCP2 was related to the stage and lymph node metastasis.Clinical verification showed that the mRNA and protein relative expressions of LCP2 in KIRC tissues were significantly higher than those in adjacent tissues (P<0.000 1). Conclusion: LCP2 is significantly up-regulated in stage Ⅰ KIRC tissues and can be used as a potential biomarker for the early diagnosis and treatment of KIRC.

Small RNAs (sRNAs), the key components of RNA interference (RNAi) or RNA silencing, can mediate cell-autonomous gene silencing and function as signaling molecules across species. Microbe-induced gene silencing (MIGS), which is based on interspecies RNAi, is an effective approach for controlling fungal diseases in crops. The enolase gene VdEno is essential for the growth and development of the fungal pathogen Verticillium dahliae, which causes cotton Verticillium wilt. In this study, we engineered Trichoderma harzianum (Th) to express the double-stranded RNA (dsRNA) targeting VdEno. The engineered strain Th-VdEnoi successfully generated VdEno-specific small interfering RNA (siVdEno). We further confirmed that Th-VdEnoi effectively induced VdEno silencing at the translational level. The results of crop protection assays revealed that the cotton plants co-inoculated with V. dahliae (strain V592) and Th-VdEnoi presented significantly reduced disease severity and lower fungal biomass in their roots than the control plants inoculated with V. dahliae alone or with V. dahliae and Th-GFPi (a control strain expressing GFP-targeting dsRNA). Collectively, our findings demonstrate that VdEno is an effective target for controlling cotton Verticillium wilt and confirm that MIGS is a promising strategy for managing soil-borne fungal pathogens in crops. MIGS provides strong technical support for reducing the application of conventional chemical pesticides, developing eco-friendly biopesticides, and facilitating the sustainable development of agriculture.
