From the results of this study, we speculate that in the development of AMI, the increase in

This study aimed to identify the key genes related to male ankylosing spondylitis (AS) and to analyze the role of immune cell infiltration in the pathological process of this disease.
The AS dataset was downloaded from the Gene Expression Omnibus (GEO) public database, and the data of male healthy controls (M_HC) and male AS patients (M_AS) were extracted. R software was used to identify differentially expressed genes (DEGs). Functional and pathway enrichment analysis of the DEGs was performed. A protein-protein interaction (PPI) network was constructed, and the hub genes were screened out. All expression profile data were analyzed by weighted correlation network analysis (WGCNA) to screen out the hub genes, which were then intersected with the hub genes from the PPI network to obtain the key genes. Finally, the difference in immune cell infiltration in the two sets of samples was evaluated with CIBERSORT, and the correlation between the key genes and infiltrating immune cells was analyzed.
A total of 689 DEGs were obtained, of which 395 genes were up-regulated and 294 genes were down-regulated. Functional and pathway enrichment analysis showed that DEGs were mainly enriched in pathways related to immune response. Based on the PPI analysis, five clusters with high scores were selected. Through WGCNA, 14 gene modules were obtained. The green module with the highest correlation was selected and intersected with the cluster previously obtained to obtain three key genes,

Attenuating oxidative stress response is an effective strategy for the treatment of wounds. Taurine is a widely abundant amino acid in mammal species, capable of inhibiting oxygen-free radicals during the inflammation phase.
A novel taurine carried biocompatible composite collagen-derived sponge, Tau@Col, was fabricated for the treatment of a full-thickness removal mouse wounds model.
experiments included taurine release from Tau@Col and cell viability when co-cultured with Tau@Col. With the prolonged release of taurine upon the wound site, Tau@Col was engineered to perform well in the wound site through inflammation inhibition and proliferation stimulation as demonstrated by a series of histological staining.
taurine release profile and good cell biocompatibility of Tau@Col were demonstrated.
studies showed that Tau@Col indeed sped up the process of wound regeneration through enhanced granulation formation, collagen deposition as well as re-epithelialization. Further investigations through immunofluorescence staining revealed that the improved wound healing ability of Tau@Col was mediated by the enhanced cell proliferation via the upregulation of endogenous vascular endothelial growth factor (VEGF) and transforming growth factor beta (TGF-β) expression as well as decreased inflammatory response through stimulated M2 polarization of macrophages.
This engineered Tau@Col delivery system has great potential as a wound dressing in future applications.

Diagnostic splenectomy is often performed on patients with suspected splenic lymphoma. TGF-beta signaling However, unnecessary splenectomy entails more harm than benefit for patients. Therefore, a preliminary screening method for patients with suspected splenic lymphoma that has high sensitivity and specificity is urgently needed.
From the pathology database at Huadong and Huashan Hospital, we retrospectively identified 60 patients of suspected splenic lymphoma who underwent fluorodeoxyglucose (FDG)-positron emission tomography (PET) before receiving a splenectomy and did not show any increase in FDG uptake except in the spleen. We compared the indicators of PET-CT, such as the maximum standardized uptake value (SUVmax), metabolic tumor volume (MTV), total lesion glycolysis (TLG), and the SUVmax of 18F-FDG uptake ratios between the spleen/liver, spleen/bone marrow, and liver/bone marrow.
No significant differences were detected in SUVmax, TLG, MTV, or the SUVmax ratio of the liver/bone marrow between the lymphoma and benign groups. However, the SUVmax ratios of the spleen/liver and spleen/bone marrow were significantly higher in the lymphoma group than in the benign group (P=0.001; P=0.001). Receiver operating characteristic (ROC) curve analysis determined a spleen/liver SUVmax ratio of >2.42 and a spleen/bone marrow SUVmax ratio of >1.45 to be the indications for requiring a diagnostic splenectomy for lymphoma. Parallel testing increased the specificity and sensitivity of the test.
Patients whose PET-CT results are inconclusive regarding the need for splenectomy may benefit from our prediction model. Future large-scale prospective clinical trials are required to verify these findings.
