Machado-Joseph disease, or spinocerebellar ataxia type 3 (SCA3), represents the most common autosomal dominant cerebellar ataxia worldwide. Despite its progressive and debilitating nature, disease-modifying therapies remain elusive. Repetitive transcranial magnetic stimulation (rTMS) has emerged as a promising non-invasive intervention; however, its clinical application has been hindered by inconsistent protocols and a lack of mechanistic understanding. A recent landmark study published in Brain Stimulation by Chen et al. addressed these challenges by combining a high-dose intermittent theta-burst stimulation (iTBS) protocol with concurrent transcranial magnetic stimulation-electroencephalography (TMS-EEG). This commentary provides an in-depth analysis of their findings, highlighting the restoration of cerebello-cortical inhibition (CBI) as a key therapeutic mechanism. Furthermore, we discuss the broader implications of this work, proposing that future translational research should integrate accelerated iTBS (aiTBS) paradigms, cortical response measurements (CRM), and individualized neuro-navigation to establish a new era of precision neuromodulation for ataxia.

Background: High-mobility group box protein 1 (HMGB1) is a chromatin-binding protein involved in arthritis, ischemia, sepsis, atherosclerosis, neurodegenerative disorders, meningitis, and cancer. HMGB1 exhibits dual roles in cancer, acting as either a tumor suppressor or oncoprotein depending on context. Objective: This research aimed to elucidate HMGB1’s functional significance in cutaneous squamous cell carcinoma (cSCC). Methods: We overexpressed HMGB1 in cSCC cell lines using recombinant adenovirus and examined its effects on cell proliferation, colony formation, and cell migration. Results: Immunohistochemical analysis revealed elevated HMGB1 expression levels in cSCC tissue relative to normal epidermis. To assess the influence of HMGB1, we employed recombinant adenoviruses expressing HMGB1 to transduce SCC cell lines (SCC12 and SCC13). Enhanced HMGB1 expression significantly promoted cellular proliferation and colony formation capacity.Notably, HMGB1 overexpression elevated the levels of proliferation regulators, including P63, SOX2, CDK4 and CDK6. Furthermore, HMGB1 overexpression substantially enhanced tumor invasiveness, accompanied by upregulation of epithelial-mesenchymal transition (EMT) biomarkers. Mechanistically, overexpression of HMGB1 enhanced transforming growth factor-β signaling by increasing phosphorylation of SMAD2/3, the key mediators of EMT. Conclusion These data imply that HMGB1 acts as a tumor-promoting factor in cSCC.

Background: and Purpose Vertebrobasilar fusiform aneurysms (VBFAs) carry substantial morbidity and mortality, but optimal management for unruptured VBFAs remains unclear. We compared the safety and efficacy of conservative management (CM), stent-assisted coiling (SAC), and flow diverters (FDs) in patients with unruptured VBFAs, focusing on long-term prognosis. Methods: This study included data from a nationwide Chinese cohort of patients with vertebrobasilar dissecting aneurysms. Inverse probability of treatment weighting (IPTW) balanced confounders across groups. The primary outcome was poor prognosis (modified Rankin Scale score >2). Secondary outcomes included aneurysm rupture, ischemic stroke, compression symptoms, and VBFA-related deaths. Logistic regression estimated odds ratios (ORs) and 95% confidence intervals (CIs). Subgroup and sensitivity analyses were performed. Results: Among 1,115 patients with unruptured VBFAs, 838 (median age, 54 years; 655 men) were included. After IPTW, baseline characteristics were balanced. Median follow-up was 54 months. FD was associated with a lower risk of poor prognosis than CM (OR, 0.48 [95% CI, 0.30 to 0.77]; p=0.002), with no difference between CM and SAC. FD also reduced aneurysm rupture (OR, 0.20 [95% CI, 0.07 to 0.60]; p=0.004) and compression symptoms (OR, 0.30 [95% CI, 0.13 to 0.68]; p=0.004) versus CM. Time-to-event analyses further revealed significant differences in vertebral artery lesions and Type I–II VBFAs, whereas no significant differences were observed in basilar or vertebrobasilar junction lesions or in Type III–IV VBFAs. Conclusions Compared with CM, FD was associated with improved long-term outcomes in unruptured VBFAs, particularly in vertebral artery lesions and Type I–II VBFAs, although residual confounding cannot be excluded.

Aimed to find a safe and effective drug to replace nitroimidazole drugs in aquaculture pro-duction for the prevention and treatment of Trichomoniasis in pigeons,which can improve the eco-nomic benefits of meat pigeon breeding and ensure food safety.Firstly,Trichomonas was isolated and cultured from the crop of diseased pigeons and identified.After stable passage,a quantitative method for in vitro detection of Trichomonas was established by combining an automated cell counter and quantitative real-time PCR technology.To prepared the drug,powders of Sophora fla-vescent and Philodendron were made into herbal water extracts(SFPA)and mixed with copper sulfate(CS)solution.Then added the drug to the culture medium of Trichomonas to determine the effective concentration of it.A total of 135 pairs each of Silver King and Mimas breeding pigeons in the same laying period were selected and randomly divided into three groups,with 6 replicates in each group and 15 pairs of breeding pigeons in each replicate.Four days before brooding,the three groups were fed with 200 mL of pure water,0.5 g/L metronidazole(MDZ)solution,and a mixed solution of 30 g/L SFPA and 0.5 g/L CS,respectively.The feeding experiment lasted for 26 d.Results showed that the mixed solution of SFPA and CS had a significant killing effect on Trichomonas in vitro(P＜0.05).Feeding the drug to breeding pigeons significantly reduced the in-fection rate of breeding pigeons by Trichomonas(P＜0.05).The drug had no significant effect on the serum biochemical indexes,antioxidant properties,immunoglobulin levels of breeding pigeons,the average cage weight,immune organ indexes,meat quality and slaughter performance of squabs(P＞0.05).The results suggested that adding SFPA and CS to pigeons can effectively prevent and treat Trichomoniasis and improve production performance.It can replace nitroimidazole drugs without affecting the immune level of breeding pigeons and the weight,immune level,slaughter performance and meat quality of squabs,thereby reduce drug residues in poultry products and en-hance the food safety.

Objective:To evaluate the clinical process of fragment reattachment in crown-root fractures (CRF) of teeth that the fracture occurred between sub-gingival and supra-alveolar ridge (sub-gingival & supra-alveolar ridge) in the esthetic zone, and to analyze the feasibility of this minimally invasive technique for sub-gingival & supra-alveolar ridge CRF involving anterior teeth.Methods:Fourteen sub-gingival & supra-alveolar ridge CRF involving anterior teeth in 12 patients received fragment reattachment in the Department of Prosthodontics, School of Stomatology, the Fourth Military Medical University from January 2016 to August 2024. The success rate of the fractured teeth 3 years after reattachment and the complications during the follow-up period were retrospectively analyzed. The 3-year success rate and complications during follow-up were evaluated to assess the clinical efficacy of this technique.Results:The 14 treated teeth were followed for an average of (36.0±33.7) months (range: 4-99 months). Complications occurred in 2 teeth: one was extracted due to debonding and replaced with a removable partial denture, while the other developed a palatal sinus post-reattachment, which healed after local saline irrigation and medication (followed for 12 months without recurrence). The remaining 12 teeth exhibited no complications, resulting in a success rate of 13/14.Conclusions:Fragment reattachment is a minimally invasive, rapid, and cost-effective treatment option for sub-gingival & supra-alveolar ridge CRF in the anterior esthetic zone. With strict case selection, it delivers favorable outcomes and extends the clinical lifespan of affected teeth.

Objective:To explore the safety and efficacy of intraosseous regional administration (IORA) of vancomycin for preventing infection in primary total knee arthroplasty (TKA).Methods:A total of 124 patients with knee osteoarthritis undergoing TKA between February 2024 and May 2024 at nine hospitals were enrolled. Preoperative infection prophylaxis involved either IORA (0.5 g vancomycin administered via intraosseous regional infusion before incision) or intravenous infusion (1 g vancomycin via peripheral vein). The IORA group included 15 males and 47 females with a median age of 66.5 years (range, 60.0-70.0 years), while the intravenous group included 14 males and 48 females with a median age of 66.0 years (range, 61.8-70.3 years) years. Intraoperative samples were collected including fat and synovium tissues after incision, before prosthesis placement, and after tourniquet release; distal femoral cancellous bone during femoral osteotomy; proximal tibial cancellous bone during tibial osteotomy; proximal intercondylar cancellous bone before prosthesis placement; and peripheral blood from non-infused arms at surgery initiation and after tourniquet release. Vancomycin concentrations were measured using liquid chromatography-tandem mass spectrometry. Vital sign changes were recorded from admission to 5~10 minutes post-IORA (IORA group) or post-incision (intravenous group). Follow-ups were conducted on postoperative day 1 and 3, and at 1 and 3 months, to document complications including IORA-related adverse events, periprosthetic joint infections, surgical site infections, red man syndrome, acute kidney injury, deep vein thrombosis and so on.Results:Vancomycin concentrations in bone, fat, and synovial tissue samples were significantly higher in the IORA group than in the intravenous group ( P<0.05), while vancomycin concentrations in blood samples were significantly lower in the IORA group than in the intravenous group ( P<0.05). Only 7.3%(41/558) of tissue samples in the IORA group had vancomycin concentrations below 2.0 μg/g (the minimum inhibitory concentration of vancomycin against coagulase-negative staphylococcus), compared to 59.3%(331/558) in the intravenous group (χ 2=11.285, P<0.001). In the intravenous group, 16.9%(21/124) of blood samples had vancomycin concentrations exceeding 15.0 mg/L (the threshold associated with a significantly increased risk of nephrotoxicity), while all concentrations in the IORA group were below this threshold, the difference was statistically significant (χ 2=22.943, P<0.001). There were no statistically significant difference ( P>0.05) in vital signs changes before and after vancomycin administration between the two groups. Two patients in the intravenous group experienced incision exudate, while no other related complications occurred in either group. Conclusions:Compared to the traditional intravenous infusion of 1 g vancomycin, intraosseous injection of a low dose (0.5 g) of vancomycin achieves higher local tissue concentrations in the knee joint with a lower incidence of adverse reactions and is safe for infection prophylaxis. Despite guidelines not recommending the routine use of vancomycin for preventing infection after primary TKA, intraosseous injection of 0.5 g vancomycin may be considered intraoperatively for primary TKA in the following scenarios: patients in medical institutions with a high prevalence of methicillin-resistant staphylococcus aureus (MRSA) infections, patients with potential preoperative MRSA colonization, or patients with cephalosporin allergy.
