Objective To observe the efficacy and safety of mechanical thrombectomy in acute ischemic stroke patients after vertebral-basilar artery stent implantation.Methods From May 2018 to October 2022,patients with acute vertebral basilar artery occlusion who underwent mechanical thrombectomy were retrospectively analyzed.The patients were divided into two groups:stent occlusion group and acute atherosclerotic stenosis occlusion(ICAS)group.The baseline characteristics of the two groups were balanced by propensity score matching method.The successful recanalization rate,90-day good outcome rate,90-day mortality rate,and symptomatic intracranial hemorrhage rate were compared.Results We enrolled 107 patients,with 14 cases in stent occlusion group and 93 cases in ICAS group.We analyzed 14 pairs by propensity score matching,including 14 cases in stent occlusion group and 27 cases in ICAS group.The successful recanalization rate and 90-day good outcome rate was lower in stent occlusion group than in ICAS group[(78.6％(11/14)vs.100％(27/27),P=0.062,28.6％(4/14)vs.44.4％(12/27),X2=0.976,P=0.323],but there was no statistical difference.The 90-day mortality rate in the stent occlusion group was significantly higher than that in the ICAS group[57.1％(8/14)vs.25.9％(7/27),x2=3.873,P=0.049].The incidence of symptomatic intracranial hemorrhage was higher in the stent occlusion group than in the ICAS group,with no statistical difference[35.7％(5/14)vs.14.8％(4/27),x2=1.289,P=0.256].Conclusion The successful recanalization rate,90-day good outcome rate,and incidence of symptomatic intracranial hemorrhage in stent occlusion group did not significantly differ from those in ICAS group,but the 90-day mortality rate was significantly higher in the former group.

Rheumatic diseases are chronic inflammatory autoimmune diseases that can affect multiple organs and systems. In clinical practice， most patients with rheumatic diseases present with asymptomatic liver function abnormalities during the course of the disease， and the etiology of such diseases may be associated with the rheumatic disease itself， medications， metabolism， viruses， or the presence of other chronic liver diseases. Immune-mediated inflammatory responses play a significant role in liver involvement （including hepatocyte injury， intrahepatic vascular lesions， and hepatic fibrosis） in rheumatic diseases. This article discusses the clinical features and management of liver involvement secondary to rheumatic diseases， in order to enhance the understanding of this condition among specialists in related fields.

The pathological hallmarks of psoriasis involve alterations in T cell genes associated with transcriptional levels, which are determined by chromatin accessibility. However, to what extent these alterations in T cell transcriptional levels recapitulate the epigenetic features of psoriasis remains unknown. Here, we systematically profiled chromatin accessibility on Th1, Th2, Th1-17, Th17, and Treg cells and found that chromatin remodeling contributes significantly to the pathogenesis of the disease. The chromatin remodeling tendency of different subtypes of Th cells were relatively consistent. Next, we profiled chromatin accessibility and transcriptional dynamics on memory Th/Treg cells. In the memory Th cells, 803 increased and 545 decreased chromatin-accessible regions were identified. In the memory Treg cells, 713 increased and 1206 decreased chromatin-accessible regions were identified. A total of 54 and 53 genes were differentially expressed in the peaks associated with the memory Th and Treg cells. FOSL1, SPI1, ATF3, NFKB1, RUNX, ETV4, ERG, FLI1, and ETC1 were identified as regulators in the development of psoriasis. The transcriptional regulatory network showed that NFKB1 and RELA were highly connected and central to the network. NFKB1 regulated the genes of CCL3, CXCL2, and IL1RN. Our results provided candidate transcription factors and a foundational framework of the regulomes of the disease.
