Purpose: The genomic characteristics of uterine sarcomas have not been fully elucidated. This study aimed to explore the genomic landscape of the uterine sarcomas (USs). Materials and Methods: Comprehensive genomic analysis through RNA-sequencing was conducted. Gene fusion, differentially expressed genes (DEGs), signaling pathway enrichment, immune cell infiltration, and prognosis were analyzed. A deep learning model was constructed to predict the survival of US patients. Results: A total of 71 US samples were examined, including 47 endometrial stromal sarcomas (ESS), 18 uterine leiomyosarcomas (uLMS), three adenosarcomas, two carcinosarcomas, and one uterine tumor resembling an ovarian sex-cord tumor. ESS (including high-grade ESS [HGESS] and low-grade ESS [LGESS]) and uLMS showed distinct gene fusion signatures; a novel gene fusion site, MRPS18A–PDC-AS1 could be a potential diagnostic marker for the pathology differential diagnosis of uLMS and ESS; 797 and 477 uterine sarcoma DEGs (uDEGs) were identified in the ESS vs. uLMS and HGESS vs. LGESS groups, respectively. The uDEGs were enriched in multiple pathways. Fifteen genes including LAMB4 were confirmed with prognostic value in USs; immune infiltration analysis revealed the prognositic value of myeloid dendritic cells, plasmacytoid dendritic cells, natural killer cells, macrophage M1, monocytes and hematopoietic stem cells in USs; the deep learning model named Max-Mean Non-Local multi-instance learning (MMN-MIL) showed satisfactory performance in predicting the survival of US patients, with the area under the receiver operating curve curve reached 0.909 and accuracy achieved 0.804. Conclusion USs harbored distinct gene fusion characteristics and gene expression features between HGESS, LGESS, and uLMS. The MMN-MIL model could effectively predict the survival of US patients.

Objective:To investigate the clinical efficacy of two-point localized injection of the depressor anguli oris (DAO) muscle combined with pan-platysma microbotox injection of botulinum toxin type A for improving the aesthetic of mouth corner.Methods:A retrospective analysis was conducted on clinical data from patients who received concomitant DAO localized injection and pan-platysma microbotox of botulinum toxin type A for improving drooping mouth corners at the Facial and Neck Plastic Surgery Center and the Limb and Scar Center of Plastic Surgery Hospital, Chinese Academy of Medical Sciences, between December 2022 and June 2025. Botulinum toxin type A was reconstituted to two concentrations: 40 U/ml and 20 U/ml for the combined injection. Patients were instructed to repeatedly perform upward puckering motions to identify the trapezoidal outline of the DAO muscle. Two injection points were uniformly marked slightly medial to the midline of the DAO muscle for dual-target injection (1.5 U each at the middle one-third and lower one-third of the muscle belly). The pan-platysma microbotox for the platysma muscle extended superiorly to a line parallel and 3-4 cm above the mandibular border, innerly to 1 cm beyond the lateral edge of the DAO muscle, inferiorly to the submental area and the anterior neck region above the clavicle, and laterally to the anterior border of the sternocleidomastoid muscle. The injection dose was 0.6 U per point, with 1 cm spacing between points, administered at the superficial subcutaneous layer. Complications were recorded. At 1-month postoperatively, efficacy was evaluated using the global aesthetic improvement scale (GAIS, scores ranging from 5 to 1, representing "much worse" to "very much improved" ) and subjective patient satisfaction (categorized as very satisfied, satisfied, dissatisfied, or very dissatisfied; satisfaction rate was calculated as the percentage of patients reporting very satisfied or satisfied among the total). Patients’ willingness to receive the same treatment in the future was also surveyed. Descriptive statistics were used for analysis.Results:A total of 21 patients were included (1 male, 20 females), with a mean age of (37.1±3.2) years (range: 34-45 years). The treatment procedures were successful. Post-treatment, 4 cases experienced pain and swelling, 8 had neck ecchymosis, and 1 had temporary asymmetry in mouth corner movement, all of which resolved within 2 weeks. The follow-up period ranged from 1 to 6 months (mean: 1.4 months). At short-term follow-up (4-6 weeks after treatment), patients reported a skin "tightening" sensation in the lower face and neck region, noting significant improvement in lower facial and neck contour, sharper bilateral jawlines, and reduced neck wrinkles. Drooping mouth corners were improved. The satisfaction survey showed that 17 patients were "very satisfied" and 5 were "satisfied", resultsing in a subjective satisfaction rate of 100%. Nineteen patients (90.5%) expressed willingness to undergo repeat treatment. The mean GAIS score was 1.45±0.69, with 14 patients achieving "very much improved", 5 patients "much improved", and 2 patients "improved" .Conclusion:The combination of two-point localized injection of the DAO muscle and pan-platysma microbotox injection of botulinum toxin into the platysma muscle effectively improve the aesthetic of mouth corners and lower facial contour through synergistic middle and superficial layer treatment. This approach aligns with anatomical and physiological merits and offers advantages such as minimal invasiveness and rapid recovery, making it applicable for patients with early signs of lower facial aging.

Objective To explore the mechanism of Angong Niuhuang pill on the neurological function of rats with spontaneous intracerebral hemorrhage based on the tumor necrosis factor-α/nuclear factor-κB(TNF-α/NF-κB)signaling pathway combined with network pharmacology.Methods The targets for treatment of intracerebral hemorrhage with Angong Niuhuang pill were obtained using the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP),High-Throughput Experiment and Refeence-guided Database of Traditional Chinese Medicine(HERB).Key targets were screened for Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analysis and molecular docking.Then,rats were randomly divided into normal control group,model group,Angong Niuhuang pill group(administered by gavage at 270 mg·kg-1·d-1),and the Western medicine group(intraperitoneal injection of 4 500 mg·kg-1·d-1+furosemide 1.8 mg·kg-1·d-1),the dosage administered was the equivalent dose ratio calculated based on the body surface area for humans and animals.The intracerebral hemorrhage model was replicated by the autologous heart blood caudate nucleus injection method.After modeling,the neurological function behavior scores,brain tissue water content,pathological changes of brain tissue,blood-brain barrier permeability,and protein expression levels of NF-κB p65,tumor necrosis factor receptor 1(TNFR1),inhibitor NF-κBα(IκBα)and TNF-α in brain tissue of each group were observed.Results A total of 216 intersection genes were selected.The results of GO enrichment analysis and KEGG pathway annotation analysis predicted that the TNF-α/NF-κB inflammatory signaling pathway was one of the main regulatory pathways.The animal experiment results showed that at 72 hours after modeling,compared with the model group,the neurological function score,brain tissue water content,and blood-brain barrier permeability index evans blue(EB)content of the Angong Niuhuang pill group were significantly decreased[neurological function score:1.62±0.62 vs.2.23±0.58,brain water content:(77.7±0.49)%vs.(79.9±0.04)%,EB content(μg/L):490.50±100.79 vs.1 966.20±94.81,all P<0.05];the pathological observation of brain tissue showed that Angong Niuhuang pill could reduce the pathological damage of brain tissue around the hematoma,repair the blood-brain barrier,and alleviate brain edema;the Western blotting results showed that Angong Niuhuang pill could inhibit the protein expression of TNF-α,TNFR1,and NF-κB p65 in brain tissue[NF-κB p65 protein expresion(NF-κB p65/β-actin):2.27±0.52 vs.5.40±0.26;TNFR1 protein expression(TNFR1/β-actin):1.49±0.33 vs.2.52±0.04,TNF-α protein expression(TNF-α/β-actin):1.40±0.13 vs.2.29±0.18,all P<0.05],promote the protein expression of IκB-α(IκB-α/β-actin):0.78±0.02 vs.0.32±0.00,P<0.05).Conclusion Angong Niuhuang pill may regulate the TNF-α/NF-κB signaling pathway by inhibiting the expression of TNFR1 and promoting the expression of IκB-α,exerting neuroprotective effects.

The cerebellum is heavily connected with other brain regions, sub-serving not only motor but also nonmotor functions. Genetic mutations leading to cerebellar dysfunction are associated with mental diseases, but cerebellar outputs have not been systematically studied in this context. Here, we present three dimensional distributions of 50,168 target neurons of cerebellar nuclei (CN) from wild-type mice and Nlgn3R451C mutant mice, a mouse model for autism. Our results derived from 36 target nuclei show that the projections from CN to thalamus, midbrain and brainstem are differentially affected by Nlgn3R451C mutation. Importantly, Nlgn3R451C mutation altered the innervation power of CN→zona incerta (ZI) pathway, and chemogenetic inhibition of a neuronal subpopulation in the ZI that receives inputs from the CN rescues social defects in Nlgn3R451C mice. Our study highlights potential role of cerebellar outputs in the pathogenesis of autism and provides potential new therapeutic strategy for this disease.
