OBJECTIVE: To explore the key target molecules and potential mechanisms of oridonin against non-small cell lung cancer (NSCLC). METHODS: The target molecules of oridonin were retrieved from SEA, STITCH, SuperPred and TargetPred databases; target genes associated with the treatment of NSCLC were retrieved from GeneCards, DisGeNET and TTD databases. Then, the overlapping target molecules between the drug and the disease were identified. The protein-protein interaction (PPI) was constructed using the STRING database according to overlapping targets, and Cytoscape was used to screen for key targets. Molecular docking verification were performed using AutoDockTools and PyMOL software. Using the DAVID database, Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis were conducted. The impact of oridonin on the proliferation and apoptosis of NSCLC cells was assessed using cell counting kit-8, cell proliferation EdU image kit, and Annexin V-FITC/PI apoptosis kit respectively. Moreover, real-time quantitative PCR and Western blot were used to verify the potential mechanisms. RESULTS: Fifty-six target molecules and 12 key target molecules of oridonin involved in NSCLC treatment were identified, including tumor protein 53 (TP53), Caspase-3, signal transducer and activator of transcription 3 (STAT3), mitogen-activated protein kinase kinase 8 (MAPK8), and mammalian target of rapamycin (mTOR). Molecular docking showed that oridonin and its key target molecules bind spontaneously. GO and KEGG enrichment analyses revealed cancer, apoptosis, phosphoinositide-3 kinase/protein kinase B (PI3K/Akt), and other signaling pathways. In vitro experiments showed that oridonin inhibited the proliferation, induced apoptosis, downregulated the expression of Bcl-2 and Akt, and upregulated the expression of Caspase-3. CONCLUSION Oridonin can act on multiple targets and pathways to exert its inhibitory effects on NSCLC, and its mechanism may be related to upregulating the expression of Caspase-3 and downregulating the expressions of Akt and Bcl-2.

Objective:To evaluate the feasibility, safety, and short-term efficacy of robot-assisted unilateral axillary approach for partial or total thyroidectomy without inflation. Methods:A retrospective analysis was performed on the clinical data of 98 patients who underwent gasless unilateral axillary approach robot-assisted resection of bilateral thyroid lesions at Sun Yat-sen University Cancer Center between October 2022 and October 2024. Perioperative indicators were recorded and compared among patients undergoing different surgical approaches（total thyroidectomy vs. bilateral partial thyroidectomy） and with different body mass index（BMI） values, including operative time, intraoperative blood loss, number of lymph nodes dissected, incidence of postoperative hoarseness, incidence of postoperative hypocalcemia, and other postoperative complications. Results:A total of 98 patients were included, of whom 78.57% were female, with a median age of 39 years（interquartile range[IQR]: 35-49） and a median BMI of 24.08 kg/m²（IQR: 21.43-25.98）. The median intraoperative blood loss was 32.14 mL（IQR: 20.00-50.00）, the median operative time was 130.0 minutes（IQR: 104.80-150.30）, and the median hospital stay was 2.01 days（IQR: 1.00-2.00）. The most common postoperative complication was transient hypocalcemia, with an incidence of 16.32%. There were no cases of permanent recurrent laryngeal nerve palsy or conversion to open surgery. Compared with the non-total thyroidectomy group, the total thyroidectomy group had a significantly longer operative time（135.10±33.28 min vs 120.30±30.53 min, P=0.033）. Subgroup analysis based on BMI showed no statistically significant differences in operative time, hospital stay, drainage volume, or incidence of hypocalcemia between patients with BMI≥25 kg/m² and those with BMI<25 kg/m². Conclusion:The gasless unilateral axillary approach for robot-assisted partial or total thyroidectomy demonstrates favorable safety, cosmetic outcomes, and feasibility. Appropriate selection of surgical techniques and meticulous protection of critical structures during the procedure can further reduce the risk of complications and optimize therapeutic outcomes.

In recent years, robot-assisted thyroid surgery has gained widespread adoption in major hospitals worldwide, offering advantages such as a shorter learning curve and superior cosmetic outcomes while overcoming the limitations of endoscopic surgery. Currently, the main surgical approaches include the transaxillary, bilateral axillo-breast（BABA）, retroauricular, and transoral vestibular routes. However, the widespread adoption of robotic thyroidectomy still faces several challenges, including technical complexity, prolonged operative time, a higher complication rate during the learning curve, and high costs. Nevertheless, when performed by experienced surgeons on carefully selected patients, robotic thyroidectomy can achieve outcomes comparable to those of conventional open transcervical thyroidectomy. This article provides a systematic review of the development and latest advances in robotic thyroid surgery.

Stem-leaf saponins from Panax notoginseng (SLSP) comprise numerous PPD-type saponins with diverse pharmacological properties; however, their role in Parkinson's disease (PD), characterized by microglia-mediated neuroinflammation, remains unclear. This study evaluated the effects of SLSP on suppressing microglia-driven neuroinflammation in experimental PD models, including the 1-methyl-4-phenylpyridinium (MPTP)-induced mouse model and lipopolysaccharide (LPS)-stimulated BV-2 microglia. Our findings revealed that SLSP mitigated behavioral impairments and excessive microglial activation in models of PD, including MPTP-treated mice. Additionally, SLSP inhibited the upregulation of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX2) and attenuated the phosphorylation of PI3K, protein kinase B (AKT), nuclear factor-κB (NFκB), and inhibitor of NFκB protein α (IκBα) both in vivo and in vitro. Moreover, SLSP suppressed the production of inflammatory markers such as interleukin (IL)-1β, IL-6, and tumor necrosis factor alpha (TNF-α) in LPS-stimulated BV-2 cells. Notably, the P2Y2R agonist partially reversed the inhibitory effects of SLSP in LPS-treated BV-2 cells. These results suggest that SLSP inhibit microglia-mediated neuroinflammation in experimental PD models, likely through the P2Y2R/PI3K/AKT/NFκB signaling pathway. These novel findings indicate that SLSP may offer therapeutic potential for PD by attenuating microglia-mediated neuroinflammation.

Objective To investigate the mechanism mediating the regulatory effect of lncRNA MAGI2-AS3 on cisplatin(DDP)resistance in non-small cell lung cancer(NSCLC).Methods MAGI2-AS3 and miR-1269a expression levels were detected by qRT-PCR in DDP-sensitive lung cancer cell lines(A549 and H1299)and their resistant counterparts(A549/DDP and H1299/DDP).In A549 and H1299 cells with MAGI2-AS3 silencing and A549/DDP and H1299/DDP cells overexpressing MAGI2-AS3,the effects of 20 μmol/L DDP on cell viability and apoptosis were examined with CCK-8 assay,colony formation assay,flow cytometry and Western blotting,and the changes in epithelial-mesenchymal transition(EMT)were assessed with wound healing and Transwell assays.The interaction between MAGI2-AS3,miR-1269a and PTEN was predicted using GEPIA,StarBase and miRDB and verified with luciferase reporter gene assay and radioimmunoprecipitation(RIP)assay.A miR-1269a mimic and pcDNA3.1-PTEN plasmid were used to perform the rescue assay.Results MAGI2-AS3 expression was significantly downregulated in lung cancer tissues(P<0.05)in association with a poor prognosis(P<0.05).In the two DDP-resistant lung cancer cell lines,MAGI2-AS3 expression was significantly lowered as compared with the sensitive cells.Silencing MAGI2-AS3 significantly enhanced cell viability and promoted EMT of A549 and H1299 cells irrespective of DDP treatment,and also decreased DDP-induced apoptosis of the cells.In A549/DDP and H1299/DDP cells,MAGI2-AS3 overexpression strongly repressed cell viability and EMT irrespective of DDP treatment and promoted DDP-induced cell apoptosis.Luciferase reporter gene and RIP assays confirmed the binding of MAGI2-AS3 with miR-1269a and the binding of miR-1269a with 3'-UTR domain of PTEN.The rescue assay demonstrated that MAGI2-AS3 acted as a sponge for miR-1269a to promote PTEN expression and downregulate AKT phosphorylation,thus inhibiting EMT and promoting DDP-induced apoptosis of A549/DDP cells.Conclusion MAGI2-AS3 enhances DDP sensitivity of NSCLC by targeted regulation of the miR-1269a/PTEN/AKT signaling axis.
