ObjectiveTo investigate the effect of modified Baduanjin exercise, as an rehabilitation exercise, on cardiopulmonary function, motor function and activities of daily living in patients with stroke. MethodsFrom January to September, 2023, 42 stroke patients in the Nanjing Qixia District Hospital were randomly divided into control group (n = 21) and experimental group (n = 21). The control group received routine rehabilitation, and the experimental group received modified Baduanjin exercise in addition, for four weeks. They were assessed with peak oxygen uptake (VO_2peak), anaerobic threshold (AT), peak oxygen pulse (VO_2peak/HR), forced vital capacity (FVC), forced expiratory volume in the first second (FEV₁), peak expiratory flow (PEF), Fugl-Meyer Assessment-upper extremities (FMA-UE), Berg Balance Scale (BBS) and modified Barthel Index (MBI) before and after intervention. ResultsVO_2peak, AT, and the scores of FMA-UE, BBS and MBI improved in the control group after intervention (|t| > 2.256, |Z| > 2.936, P < 0.05); while VO_2peak, AT, VO_2peak/HR, FVC, FEV₁, PEF, and the scores of FMA-UE, BBS and MBI improved in the experimental group (|t| > 4.390, |Z| > 3.451, P < 0.001); and all the indexes were better in the experimental group than in the control group (|t| > 4.136，|Z| > 2.751，P < 0.01), except the scores of BBS and MBI. ConclusionModified Baduanjin exercise can improve the cardiopulmonary function and upper limb motor function for stroke patients.

The effective local management of oligometastatic non-small cell lung cancer (NSCLC) has the potential to prolong patients' survival. The role of radiotherapy as a local treatment modality in patients with oligometastatic NSCLC, whether as first-line therapy or consolidation therapy, remains uncertain. Several studies have demonstrated that stereotactic ablative radiotherapy can offer clinical benefits for patients with oligometastatic NSCLC without increasing adverse reactions. Furthermore, the exploration of the potential synergistic effects of combining radiotherapy and immunotherapy on extending progression-free survival and overall survival in patients with oligometastatic NSCLC is also a topic worthy of attention.

Objective To analyze the current situation and characteristics of risk factors in antithrombotic therapy(in-cluding antiplatelet and anticoagulant treatments)at home and abroad,and to provide a theoretical basis for the prevention and treatment of thrombosis or bleeding associated with antithrombotic therapy.Methods The literature on risk factors of an-tithrombotic therapy published in Chinese databases(China Journal Full-text Data,Wanfang Database,VIP Database)and Eng-lish databases(PubMed,Web of Science,MEDLINE)from January 2011 to November 2021 was searched and bibliometric analy-sis was performed.The visualization analysis was performed using VOS viewer software.Results A total of 595 publications were included in the analysis.The top three countries for English publications were the USA,China,and Japan.The type of stud-ies were predominantly cohort studies,with sample sizes mostly being below 1 000.Risk factors for antithrombotic therapy are cat-egorized into those affecting antiplatelet drugs,warfarin,and new oral anticoagulants.Age,gender,renal function,and combination of antithrombotic drugs are common risk factors,and different risk factors of antithrombotic drugs also have their characteristics.Conclusion While there is substantial research on risk factors in antithrombotic therapy globally,the sample size needs to be improved.Pharmacists should provide individualized medication services based on different drugs and different groups to ensure medication safety for patients.

Objective:To explore the potential pathogenesis of exosome-mediated polymyositis/dermatomyositis (PM/DM) through multi-omics combined with bioinformatic analysis approach and to identify potential new targets for the diagnosis and treatment of PM/DM.Methods:Collect serum exosome samples from PM/DM patients and healthy individuals who underwent physical examination in Wuxi Second People′s Hospital from January 2021 to June 2023. HiSeq high-throughput sequencing technology and iTRAQ quantitative proteomics techniques were used to perform a sequencing analysis of miRNA and protein components in serum exosomes from patients with PM/DM and healthy control. R language was adapted to conduct the limma differential analysis, gene ontology (GO), Kyoto encyclopedia of genes and genomes (KEGG), gene set enrichment analysis (GSEA) functional analysis, and immunological correlation analysis. Based on these analysis, we identified core genes and established a miRNA-target gene-transcription factor co-expression molecular network. Subsequently, we employed quantitative real-time PCR (qRT-PCR) to experimentally validate the core genes. Data analysis was performed using t-test statistical analysis and receiver operating characteristic (ROC) curves were plotted to evaluate the test efficacy of the core genes. Results:Initially, 42 up-regulated differential proteins and 61 DEP down-regulated differential proteins, as well as 22 up-regulated differential miRNAs and 19 down-regulated miRNAs were screened, and 7 core genes, 13 associated differential miRNAs, and 4 transcription factors were finally identified. Based on the functional analysis we concluded that the core genes CTSG, MPO, H1-5 involved in the formation of neutrophil extracellular trap network, NF-κB pathway and other inflammation-related pathways might play an important role in exosome-mediated PM/DM pathogenesis. Immune cells such as mast cells, immature dendritic cells, natural killer cells, regulatory T cells, and helper T cells 2 were expressed to a higher extent in the disease. In the t-test, MPO [(1.08 ±0.47) vs. (2.05 ±0.62), t=-3.50, P=0.004], CTSG [(1.11 ±0.51 ) vs. (2.27 ±1.10 ), t=-2.72, P=0.022], and H1-5 [(1.03 ±0.25) vs. (1.81 ±0.73), t=-2.89, P=0.019] showed statistically significant differences. In the ROC curve analysis, MPO[AUC(95% CI): 0.92(0.78, 1)], CTSG [AUC(95% CI): 0.81(0.59, 1)], and H1-5 (AUC (95% CI)= 0.84(0.64, 1)] indicated that the three core genes had good accuracy. Conclusion:We identified the key differential molecules in serum exosomes of patients with PM/DM, and constructed a regulatory network of miRNA-target gene-transcription factor, and determined that the pathogenic mechanism of PM/DM was mediated by serum exosomes was mediated through the formation of neutrophil extracellular trapping nets and the NF-κB pathway. CTSG, MPO, and H1-5 are the core genes in the these pathways, and their related miRNAs and transcription factors have been identified, which may become potential targets and biomarkers for the diagnosis and treatment of PM/DM.
