OBJECTIVE To study the protective effect and potential mechanism of chikusetsu saponin Ⅳ a (chsⅣ) on renal function in diabetic nephropathy (DN) model rats. METHODS DN rat model was established by high-fat diet combined with streptozotocin injection. Thirty-six model rats were randomly divided into model group (i.g. administration of normal saline, high-fat diet), chsⅣ low-dose and high-dose groups (i.g. administration of 90, 180 mg/kg chsⅣ, high-fat diet), with 12 rats in each group. Additionally, 10 normal rats were set as the control group (i.g. administration of normal saline, regular diet). From the 5th to the 12th week after streptozotocin injection, they were given intragastric administration of relevant drug or normal saline, once a day. After the last medication, the levels of fasting blood glucose, fasting insulin, blood urea nitrogen, serum creatinine and urine protein as well as the levels of reduced glutathione (GSH), superoxide dismutase (SOD) and malondialdehyde (MDA) in renal tissues were measured. Additionally, the insulin resistance index was calculated. Hematoxylin-eosin, periodic acid-Schiff, and Masson staining techniques were employed to examine the histopathological alterations in the renal tissue. The expressions of Notch signaling pathway-related proteins in renal tissue were detected by immunohistochemical staining and Western blot methods. RESULTS Compared with model group, the histomorphological of renal tissues in the chsⅣ low- and high-dose groups were significantly improved, with significant decreases in renal histological scores, mesangial expansion index, and glomerulosclerosis scores ( P <0.05); the levels of fasting blood glucose, fasting insulin, blood urea nitrogen, serum creatinine, urine protein and homeostasis model assessment for insulin resistance, as well as MDA content, the expression levels of Notch1, Notch intracellular domain, hairy and enhancer of Split 1 and Delta-like protein 1 in renal tissue were all significantly decreased ( P <0.05). The levels of GSH and SOD in renal tissue were significantly elevated ( P <0.05). Moreover, the improvement in these indicators was significantly more pronounced in the chsⅣ high-dose group compared to the chsⅣ low-dose group ( P <0.05). CONCLUSIONS ChsⅣ can ameliorate renal pathological damage and functional impairment in DN rats. Its underlying mechanisms include restoration of glucose homeostasis and insulin sensitivity, attenuation of renal oxidative stress, and suppression of aberrant Notch signaling pathway activation.

ObjectiveTo investigate the effect of interfering with long noncoding RNA (LncRNA) small nucleolar RNA host gene16 (SNHG16) on improving angiogenesis of ectopic endometrial stromal cells (EScs) in adenomyosis (AM) by targeting upregulation of miRNA (miR)-141-3p and inhibition of high mobility group box-1 protein (HMGB1). MethodsThe expression levels of SNHG16, miR-141-3p and HMGB1 mRNA in endometrial tissues of 52 patients with adenomyosis (AM group) and 52 patients who needed hysterectomy due to cervical cancer or ovarian cancer (control group) were detected by quantitative reverse transcription polymerase chain reaction (qRT-PCR). Y14 cells were divided into small hairpin RNA (shRNA) NC group, shRNA SNHG16 group, shRNA SNHG16+miR-141-3p inhibitor (inhibitor) group, shRNA SNHG16+inhibitor NC group and blank group. The targeting relationship between miR-141-3p and SNHG16 as well as HMGB1 was verified. The expression levels of SNHG16, miR-141-3p and HMGB1 mRNA in Y14 cells were detected by qRT-PCR. CCK-8 and Transwell assay were used to detect cell proliferation, invasion and migration. Microvascular density (MVD) was determined by immunofluorescence. The expressions of hypoxia-inducing factor α (HIF-1α), cyclooxygenase-2 (Cox-2), vascular endothelial growth factor (VEGF) and HMGB1 were detected by Western blot. ResultsThe expression of SNHG16 and HMGB1 mRNA in AM group was higher than that in control group, but the expression of miR-141-3p was lower than that in control group (P0.05). The expression of SNHG16, HMGB1 mRNA, proliferation rate, migration, invasion number, MVD, expression of VEGF, HIF-1 α, Cox-2, and HMGB1 proteins in the shRNA SNHG16 group were lower than those in the blank group and shRNA NC group, while the expression of miR-141-3p was higher than that in the blank group and shRNA NC group (P0.05). Inhibition of miR-141-3p reversed the improvement of EScs angiogenesis by interfering with SNHG16. ConclusionInterference with LncRNA SNHG16 improves EScs angiogenesis and inhibits proliferation, migration, and invasion of EScs by targeting upregulation of miR-141-3p and inhibition of HMGB1.

Objective To analyze the clinical efficacy and safety of transurethral blue laser vaporization of prostate (BVP) in the treatment of benign prostatic hyperplasia (BPH), and to explore the feasibility of its promotion in primary hospitals. Methods Clinical data of 30 BPH patients undergoing BVP in our hospital during Sep. and Dec. 2024 were retrospectively analyzed. The preoperative prostate volume, decrease in hemoglobin level 2 hours after operation, operation time, postoperative bladder irrigation time, catheter indwelling time, and intra-/postoperative complications were recorded. The changes of international prostate symptom score (IPSS), quality of life (QoL) score, and maximum urinary flow rate (Qmax) were compared before operation and 6 months after operation. Results The mean prostate volume was (46.9±15.7) mL. BVP was successfully completed in 28 patients. The 2 unsuccessful cases (6.7%) converted to transurethral resection of the prostate (TURP) due to intraoperative bleeding. For the 28 successful cases, the median postoperative 2-hour hemoglobin decrease was 4 (2, 11) g/L, mean operation time (59.8±13.2) min, median postoperative bladder irrigation time 21 (18, 23) h, median postoperative catheter indwelling time 5 (5, 5) d, and median postoperative hospital stay 6 (5, 6) d. After catheter removal, urinary retention with infection occurred in 1 case (3.6%), and hemorrhage in 1 case (3.6%). No severe complications occurred during the perioperative period. At 6 months postoperatively, the 28 patients showed significant improvement compared to preoperative values in IPSS[11 (10, 11) vs. 22 (21, 26), P<0.001], QoL score[2 (2, 3) vs. 5 (5, 6), P<0.001], and Qmax[ (17.2±5.6) mL/s vs. (7.8±1.4) mL/s, P<0.001]. Conclusion BVP is a safe and effective treatment for BPH, offering advantages such as minimal blood loss, short operation time, and few complications. It effectively improves patients' lower urinary tract symptoms and quality of life, and is recommended for promotion in primary hospitals.

NOD-like receptor thermal protein domain associated protein 3 (NLRP3) inflammasome mediates inflammation, induces pyroptosis, and regulates periodontal tissue remodeling through the maturation and secretion of its downstream cysteine protease 1 (Caspase-1)-dependent pro-inflammatory cytokines, interleukin (IL)-1β and IL-18. Orthodontic force mediates the aseptic inflammation of periodontal tissues and triggers adaptive alteration of periodontal tissues, thereby promoting the movement and stability of orthodontic teeth. NLRP3 inflammasome plays an important role in orthodontic tooth movement and causes periodontal tissue inflammation and orthodontic inflammatory root resorption in orthodontic patients. Literature review suggests that NLRP3 inflammasome is involved in the activation and differentiation of periodontal ligament fibroblasts, periodontal ligament stem cells, macrophages, osteoblasts, and osteoclasts in orthodontic tooth mobile tissue remodeling. Additionally, it targets the upstream nuclear factor kappa-B signaling pathway; downstream effectors, such as Caspase-1, IL-1β, and IL-18; and the NLRP3 inflammasome components for regulating tooth movement as well as treating and preventing orthodontics-associated periodontitis and orthodontic-induced inflammatory root resorption. Future studies can be focused on the specific mechanism of NLRP3 inflammasome tissue modification during orthodontic tooth movement. This article reviews the effects and regulatory mechanisms of the NLRP3 inflammasome signaling pathway on the corresponding tissue remodeling during orthodontic tooth movement.

Heritable aortic disease (HAD) is characterized by thoracic aortic aneurysm/dissection with strong genetic predisposition and high clinical phenotypic heterogeneity. HAD is one of the main causes of sudden death. Early diagnosis of this disease is difficult because of atypical clinical symptoms, leading to the deterioration of disease with the development of aortic aneurysm, aortic dissection or sudden death. Genetic testing plays an important role in the early diagnosis, standardized follow-up, screening of family members, genetic counseling and individualized treatment of HAD. This review focused on the application of genetic testing in the standardized diagnosis and treatment of HAD.

Objective To assess the clinical value of a novel surgical technique—Tubeless subxiphoid uniportal video-assisted thoracoscopic surgery with percutaneous suspension technique via balance-shaped sternal elevation device in the resection of anterior mediastinal masses. Methods Patients who underwent tubeless subxiphoid uniportal video-assisted thoracoscopic surgery via balance-shaped sternal elevation device in anterior mediastinal masses process at the Department of Thoracic Surgery, West China Hospital, Sichuan University from March to April 2025 were included, and their clinical data were analyzed. Results A total of 4 patients were included, with 2 males and 2 females, aged 58-75 years. The diameter of the tumor was 2.5-3.0 cm. The operation time was 60.0-150.0 min, intraoperative blood loss was 5-10 mL, pain score on the 3rd day after surgery was 0 points, and postoperative hospital stay was 2-3 days. All patients achieved complete resection of the masses and thymus without perioperative complications. Conclusion The tubeless subxiphoid uniportal video-assisted thoracoscopic surgery with percutaneous suspension technique via balance-shaped sternal elevation device technique optimizes surgical visualization and instrument maneuverability while avoiding complications related to conventional anesthesia and tubing, thereby markedly enhancing the minimally invasive profile of anterior mediastinal masses resections. In addition to maintaining procedural safety, this approach effectively reduces postoperative pain and accelerates patient recovery, highlighting its potential for widespread clinical adoption.

Background: Epimedii Folium, first recorded in the Shennong’s Classic of Materia Medica (Shen Nong Ben Cao Jing), is a traditional Chinese medicine (TCM) known for its effects of “benefiting Qi and strengthening the heart.” Icariside II (ICS II) is one of the main active components of Epimedii Folium, possessing cardiovascular protective and anti-inflammatory properties. However, the potential mechanisms of ICS II on myocardial ischemia (MI) remain unclear. Objective: The aim of the study was to investigate the effects and preliminary molecular mechanisms of ICS II in treating isoproterenolinduced MI in rats. Methods: A rat model of MI was established by subcutaneous injection of isoproterenol. Electrocardiography, echocardiography, myocardial enzymes analysis, heart weight index, triphenyltetrazolium chloride staining, histopathology, TUNEL staining, RT-qPCR, and Western blot were employed to evaluate the effects and preliminary molecular mechanisms of ICS II on MI rats. Results: Pharmacodynamic studies suggested that ICS II inhibited ST-segment elevation in electrocardiograms, improved cardiac function, reduced heart weight index and myocardial enzyme levels, decreased myocardial infarct size, alleviated cardiac histological damage, and inhibited apoptosis, thereby exerting cardioprotective effects in MI rats. Further studies revealed that ICS II may partially inhibit the expression of NLRP3/Caspase-1 axis-related targets at both protein and mRNA levels. Conclusions: Our findings indicate that ICS II exerts anti-MI effects, and its preliminary molecular mechanisms may be related to inhibiting the activation of the NLRP3/Caspase-1 axis to alleviate inflammatory responses.

Neddylation is a crucial posttranslational modification that involves the attachment of neural precursor cell-expressed developmentally downregulated protein 8(NEDD8)to a lysine residue in the substrate via the sequential actions of the E1 NEDD8-activating enzyme(NAE)(E1),E2 NEDD8-conjugating enzyme(E2),and E3 NEDD8-ligase(E3).The most extensively studied substrates of neddylation are members of the cullin family,which act as scaffold components for cullin ring E3 ubiquitin ligases(CRLs).Since cullin neddylation activates CRLs,which are frequently overactive in tumors,inhibiting neddylation has emerged as a promising strategy for developing novel antitumor therapies.This review explores the antitumor effects of inhibiting neddylation that leads to the inactivation of CRLs and provides a summary of known inhibitors that target protein-protein interactions(PPIs)within the neddylation enzymatic cascade.
