To report two cases of psychiatric symptoms associated with zonisamide, an antiepileptic drug, and raise clinical awareness of this potential adverse effect. Two male patients with epilepsy treated with zonisamide were retrospectively analyzed. Case 1 (25 years old) developed acute emotional and behavioral abnormalities (e.g., insomnia, aggression, incoherent speech) after switching from sodium valproate to zonisamide (200 mg/day). Case 2 (48 years old) had long-term zonisamide use (≥5 years) with persistent treatment-resistant psychotic symptoms (e.g., delusions, command hallucinations). Clinical courses, medication adjustments, and symptom responses were documented. In Case 1, psychiatric symptoms resolved after discontinuing zonisamide and switching to sodium valproate, with improved mood stability and reduced impulsivity. In Case 2, despite escalating antipsychotic medications (risperidone, clozapine), psychotic symptoms persisted, likely due to ongoing zonisamide use. Both cases highlighted zonisamide’s potential to exacerbate or induce psychiatric manifestations, possibly via mechanisms involving sodium/calcium channel inhibition and neurotransmitter dysregulation (e.g., dopamine, serotonin). Zonisamide can cause or worsen psychiatric symptoms, particularly in vulnerable individuals. Clinicians should monitor for mental health changes during zonisamide treatment and consider drug discontinuation or substitution with alternative antiepileptics (e.g., sodium valproate) if psychiatric adverse effects emerge. Awareness of this association is crucial to avoid misdiagnosis and optimize epilepsy management.

Aim To investigate the promotive effects and mechanisms of the combined use of brucine(Bru)and lumbrokinase(LK),active ingredient derived from Longma formula,in promoting chondrocyte proliferation via the Wnt/β-catenin signaling pathway.Methods The extracted primary rat chondrocytes were divided in-to the following groups:Control group,Bru,LK alone group,and Bro+LK combination group.The optimal drug concentration and intervention time were deter-mined using CCK-8 assay,followed by cell proliferation validation through EdU and phalloidin staining.The expression levels of collagen Ⅱ,aggrecan and SRY-re-lated high-mobility group box gene 9(SOX9)in chon-drocytes following intervention with the combination of Bru and LK were detected by Western blotting.Addi-tionally,the regulatory effects of these proteins on the Wnt/β-catenin signaling pathway were also investiga-ted.Results The optimal combination concentration of Longma formula active ingredients(Bru 0.025 mg·L-1+LK 5 mg·L-1)significantly enhanced chondro-cyte viability compared to control,Bru,or LK alone at 48 h.This combination increased the S-phase ratio,promoted the aggregation of intracellular actin fila-ments,and upregulated the expression of collagen Ⅱ and aggrecan.Furthermore,it activated the Wnt/β-catenin pathway,leading to increased SOX9 expres-sion.Conclusions The optimal combination of Bru and LK(Bru 0.025 mg·L-1+LK 5 mg·L-1)de-rived from Longma formula significantly maintains chondrocyte phenotype and promotes cellular prolifera-tion through the activation of the Wnt/β-catenin signa-ling pathway,which subsequently upregulates the downstream target SOX9.

BACKGROUND:
Previous evidence showed that ambient air pollution and cardiovascular mortality are related. However, there is a lack of evidence towards the modification effect of long-term lifestyle on the association between short-term ambient air pollution and death from cardiovascular events.
METHOD:
A total of 14,609 death from major adverse cardiovascular events (MACE) were identified among the China Kadoorie Biobank participants from 2013 to 2018. Ambient air pollution exposure including particulate matter 2.5 (PM2.5), SO2, NO2, CO, and O3 from the same period were obtained from space-time model reconstructions based on remote sensing data. Case-crossover design and conditional logistic regression was applied to estimate the effect of short-term exposure to air pollutants on MACE mortality.
RESULTS:
We found MACE mortality was significantly associated with PM2.5 (relative percent increase 2.91% per 10 µg/m3 increase, 95% CI 1.32-4.53), NO2 (5.37% per 10 µg/m3 increase, 95% CI 1.56-9.33), SO2 (6.82% per 10 µg/m3 increase, 95% CI 2.99-10.80), and CO (2.24% per 0.1 mg/m3 increase, 95% CI 1.02-3.48). Stratified analyses indicated that drinking was associated with elevated risk of MACE mortality with NO2 and SO2 exposure; physical inactivity was associated with higher risk of death from MACE when exposed to PM2.5; and people who had balanced diet had lower risk of MACE mortality when exposed to CO and NO2.
CONCLUSIONS
The study results showed that short-term exposure to ambient PM2.5, NO2, SO2, and CO would aggravate the risk of cardiovascular mortality, yet healthy lifestyle conduct might mitigate such negative impact to some extent.

Recent clinical trials have demonstrated a protective effect in using traditional Chinese medicine Tongxinluo (TXL) capsule to treat atherosclerosis. However, clinical evidence of the effects of TXL treatment on coronary plaque vulnerability is unavailable. In response, we developed this study to investigate the hypothesis that on the basis of statin therapy, treatment with TXL capsule may stabilize coronary lesions in patients with acute coronary syndrome (ACS). The TXL-CAP study was an investigator-initiated, randomized, double-blind clinical trial conducted across 18 medical centers in China. Patients with ACS aging from 18 to 80 years old who had a non-intervened coronary target lesion with a fibrous cap thickness (FCT) < 100 μm and lipid arc > 90° as defined by optical coherence tomography (OCT) were recruited. A total of 220 patients who met the selection criteria but did not meet the exclusion criteria will be finally recruited and randomized to receive treatment with TXL (n = 110) or placebo (n = 110) for a duration of 12 months. The primary endpoint was the difference in the minimum FCT of the coronary target lesion between TXL and placebo groups at the end of the 12-month follow-up. Secondary endpoints included: (1) changes of the maximum lipid arc and length of the target plaque, and the percentage of lipid, fibrous, and calcified plaques at the end of the 12-month period; (2) the incidence of composite cardiovascular events and coronary revascularization within the 12 months; (3) changes in the grade and scores of the angina pectoris as assessed using the Canadian Cardiovascular Society (CCS) grading system and Seattle angina questionnaire (SAQ) score, respectively; and (4) changes in hs-CRP serum levels. The results of the TXL-CAP trial will provide additional clinical data for revealing whether TXL capsules stabilizes coronary vulnerable plaques in Chinese ACS patients.

OBJECTIVE To investigate the mechanism of gossypol acetic acid(GAA)in the treatment of uterine fibroids.METHODS Human leiomyoma cells SK-UT-1 were selected as objects to investigate the effects of different concentrations(5,10,20,40,80,160 μmol/L)of GAA on the activities of cell proliferation.4D-DIA proteomic detection and bioinformatics analysis were carried out to screen differential proteins.Gene ontology(GO)analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG)signaling pathway analysis were performed.The expressions of top 3 proteins[N-myc downstream regulated gene 1(NDRG1),epidermal growth factor receptor feedback inhibitor 1(ERRFI1),CXC chemokine ligand 3(CXCL3)]with differential fold changes in SK-UT-1 cells were determined.RESULTS 10-160 μmol/L GAA could significantly reduce the survival rate of SK-UT-1 cells(P<0.05).Proteomics results showed that a total of 921 differentially expressed proteins were obtained,including 254 up-regulated proteins and 667 down-regulated proteins.The differentially expressed proteins were mainly distributed in mitochondria,nucleus,extracellular matrix,etc.Bioinformatics results showed that differentially expressed proteins were mainly involved in signaling pathways such as PI3K/AKT(phosphoinositide 3-kinase/protein kinase B),MAPK(mitogen-activated protein kinase),TNF(tumor necrosis factor),etc.,which mainly involved cell apoptosis,aging,and movement.GAA significantly decreased protein expressions of NDRG1 and CXCL3(P<0.05),but increased protein expression of ERRFI1(P<0.05).CONCLUSIONS The improvement effect of GAA on uterine fibroids may involve signaling pathways such as PI3K/AKT,MAPK,TNF,etc.It can improve the occurrence and development of uterine fibroids by downregulating the expressions of NDRG1 and CXCL3 proteins,upregulating the expression of ERRFI1 protein,and affecting the proliferation and apoptosis of uterine fibroid cells.

Objective To explore the clinical features,treatment and prognosis of glioblastomas(GBM)in adults.Methods A retrospective cohort study was performed on 176 adult GBM patients admitted to our department from January 2015 to December 2021.Chi-square test was used to investigate the clinical differences between isocitrate dehydrogenase(IDH)mutant and wild-type GBM.Kaplan-Meier and Log-Rank tests were employed to plot survival curve and compute the survival analysis.Multivariate Cox regression model was applied to identify the independent prognostic factors.Results IDH wild-type GBM account for 89.2%and had significantly differences from the IDH-mutant GBM in terms of age of onset,Karnofsky(KPS)score at admission,symptoms of neurological deficit,and methylation status of O6-methylguanine-DNA-methyltransferase(MGMT)promoter(P<0.05).For the IDH wild-type GBM patients receiving conventional therapy,univariate Cox hazard analysis showed gross total resection,methylation of MGMT promoter,initiation of radiation within the 5th to 6th week after surgery,and adjuvant temozolomide(TMZ)chemotherapy ≥6 cycles were favorable prognostic factors for overall survival(OS);GBMs in the left hemisphere,involvement of single lobe,methylation of MGMT promoter,and initiation of radiation within the 5th to 6th week after surgery were favorable prognostic factors for progression free survival(PFS)(all P<0.05).Moreover,multivariate Cox hazard regression analysis indicated that methylation of MGMT promoter,and initiation of radiation within the 5th to 6th week after surgery,and adjuvant TMZ chemotherapy ≥6 cycles were independent protective factors for OS,and GBMs in the left hemisphere,involvement of single lobe and methylation of MGMT promoter were independent protective factors for PFS in the GBM patients(all P<0.05).Conclusion The clinical and prognostic features are totally different between IDH mutant and wild-type GBM,and molecular detections are needed for the further pathological classification.Methylation of MGMT promoter is a primary marker of favorite prognosis for IDH wild-type GBM,and slightly delay in radiotherapy(the 5th to 6th week after surgery)can effectively improve the survival prognosis of IDH wild-type GBM.
