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.

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.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To evaluate the effect of ultrasound-guided anterior quadratus lumborum block at the supra-arcuate ligament (SA-AQLB) on the quality of postoperative recovery in patients undergoing laparoscopic surgery.Methods:In this randomized controlled study, 110 American Society of Anesthesiologists Physical Status classification Ⅰ-Ⅲ patients, aged 18-80 yr, with a body mass index of 18-28 kg/m 2, scheduled for elective laparoscopic surgery, were assigned to 2 groups( n=55 each) using a random number table method: transversus abdominis plane block (TAPB) group (group T) and SA-AQLB group (group S). The patients were sent to postanesthesia care unit and connected to patient-controlled intravenous analgesia (PCIA) pump after surgery. T group received ultrasound-guided bilateral TAPB and S group received ultrasound-guided bilateral SA-AQLB at 5 min after removal of the endotracheal tube under ultrasound guidance, with 30 ml of 0.25% ropivacaine injected on each side. Oxycodone 3-5 mg or diazoxide 5 mg was intravenously injected when the numerical rating scale score ≥4, and the requirement for rescue analgesia was recorded. The time to the first pressing and effective pressing times of PCIA were recorded, and the equivalent consumption of sufentanil at 24 h after operation was also recorded.The Quality of Recovery-15 scores were recorded at 24 and 48 h after surgery. The time to first ambulation and postoperative length of hospital stay were recorded. The occurrence of postoperative dizziness, nausea and vomiting, respiratory depression and nerve block complications was recorded. Results:Compared with group T, the equivalent consumption of sufentanil at 24 h postoperatively was significantly decreased, the effective pressing times of PCIA were reduced, the rate of rescue analgesia was decreased, the time to the first pressing of PCIA was prolonged, Quality of Recovery-15 scores were increased at 24 and 48 h after surgery, and the time to first ambulation and postoperative length of hospital stay were shortened in group S( P<0.05). Conclusions:Ultrasound-guided SA-AQLB is more effective than TAPB in improving the quality of postoperative recovery in patients undergoing laparoscopic surgery.

Objective:To generate a chronic lymphocytic leukemia (CLL) mouse model with intact immune competence and short latency by adoptively transferring (AT) splenocytes from immunoglobulin heavy-chain enhancer-driven T-cell leukemia/lymphoma 1 (Eμ-TCL1) transgenic donors into wild-type (WT) recipients.Methods:Specific pathogen-free C57BL/6J WT mice and H11-Eμ-VH-TCL1-β-globin-PolyA knock-in mice were utilized. The H11-Eμ-VH-TCL1-β-globin-PolyA knock-in mice were generated using CRISPR/Cas9 technology, and their genotypes were confirmed by PCR. Experimental animals were randomly divided into an adoptive transfer (AT) group and a WT control group ( n=10 per group). Mice in the AT group received an intraperitoneal injection of splenocytes from H11-Eμ-VH-TCL1-β-globin-PolyA knock-in mice. The weight and general condition of the mice were monitored. Mice were euthanized by cervical dislocation at 9 weeks post-transplantation. The CLL model was validated using key indicators, including pathological manifestations, changes in peripheral blood leukocyte counts, and immunophenotype. Results:AT group mice exhibited significantly increased spleen weight [ (0.92±0.16) g vs (0.06±0.01) g in WT group, P<0.05] and liver weight [ (2.11±0.56) g vs (1.42±0.13) g in WT group, P=0.006], indicative of marked splenomegaly and hepatomegaly. The peripheral blood leukocyte count was significantly higher in the AT group [ (124.33±8.74) ×10 9/L] compared to the WT group [ (5.55±1.67) ×10 9/L] ( P=0.002). Similarly, the percentage of peripheral blood B lymphocytes was markedly increased in the AT group versus the WT group [ (69.13±6.88) % vs (39.78±5.94) %, P<0.05]. Histopathological examination revealed CLL manifestations in the spleen, lymph nodes, and bone marrow of AT group mice, with significant lymphocytic infiltration observed in the liver, lung, and kidney tissues. Flow cytometry analysis showed that the percentages of CD19 +CD5 + B lymphocytes among total lymphocytes in peripheral blood, bone marrow, and spleen of the AT group were (61.37±9.92) %, (28.61± 7.08) %, and (86.03±5.78) %, respectively. These were significantly higher (all P<0.05) than in the WT group [ (4.51±1.32) %, (5.58±1.46) %, and (14.33±3.20) %]. Furthermore, these CLL-like cells in the AT group were positive for CD43 and CD200, but showed lower expression of CD20, CD22, and CD79b compared to WT B cells. Conclusion:Adoptive transfer of splenocytes from Eμ-TCL1 transgenic mice successfully established a CLL mouse model with a relatively short latency period. This model represents a valuable preclinical tool for investigating CLL and related pathologies.

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.
