Objective To explore the network structure of anxiety,depression and sleep among individuals under long-term high-altitude exposure.Methods A total of 303 subjects who had resided at high altitudes for more than 6 months on end were selected.The insomnia severity index(ISI),patient health questionnaire(PHQ-9),and generalized anxiety disorder scale(GAD-7)were employed to assess insomnia,depression and anxiety before network analysis was conducted to identify the central and bridge nodes in the symptom network.Results The incidence of moderate or severe depression,anxiety and insomnia were 38.9％[95％confidence interval(CI):33.4％-44.5％],23.1％(95％CI:18.3％-27.9％),and 18.5％(95％CI:14.1％-22.9％),respectively."Noticeability of sleep problems by others"had the highest expected influence centrality,followed by"sleep maintenance""uncontrollable worry""restlessness"and"sleep problems".Five bridge symptoms were identified:"sad mood""sleep problems""restlessness""feeling afraid"and"trouble relaxing".Conclusion Sleep-related symptoms play a crucial role in the overall network structure,serving as both central and bridge nodes.Additionally,the"feeling down or depressed"acts as a bridge node and holds importance in the comorbidity network of anxiety and depression.Targeting these key symptoms through intervention and prevention strategies may improve the psychological well-being of individuals with long-term residence in high-altitude regions.

Sepsis triggers a systemic inflammatory response that can lead to acute lung injury (ALI). Salidroside (SAL) has many pharmacological activities such as antiinflammatory and anti-oxidation. The objective of the study was to explore the mechanism of SAL on ALI caused by sepsis. A model of ALI in septic mice was established by cecal ligation and puncture. Following SAL treatment, the effect of SAL on the ferroptosis pathway in mice was analyzed. The pathological damage of lung tissue, the levels of inflammatory factors and apoptosis in bronchoalveolar lavage fluid (BALF) of mice were evaluated, and the changes of gene expression level and metabolite content abundance were explored by combining transcriptomics and metabolomics analysis. The effect of SAL on ferroptosis in mice with lung injury was observed by intraperitoneal injection of ferroptosis activator Erastin or ferroptosis inhibitor Ferrostatin-1 to promote or inhibit ferroptosis in mice. SAL significantly alleviated the pathological damage of lung tissue, decreased the number of TUNEL positive cells and the levels of TNF-α, IL-1β, IL-6 in BALF, and increased the level of IL-10 in lung injury mice. Moreover, the Fe 2+ content and malondialdehyde decreased significantly, the reactive oxygen species and glutathione content increased significantly, and the arachidonic acid metabolites 20-hydroxyeicosatetraenoic acid (20-HETE), (5Z, 8Z, 10E, 14Z)-12-Oxoeicosa-5,8,10,14-tetraenoic acid (12-OxOETE), (5Z, 8Z, 10E, 14Z)-(12S)-12-Hydroxyeicosa-5,8,10,14-tetraenoic acid (12(S)-HETE), (5Z, 8Z, 14Z)-11,12-Dihydroxyeicosa-5,8,14-trienoic acid (11,12-DHET), (5Z, 11Z, 14Z)-8,9-Dihydroxyeicosa-5,11,14-trienoic acid, Leukotriene B4, Leukotriene D4 were significantly up-regulated after SAL treatment. Salidroside alleviates ALI caused by sepsis by inhibiting ferroptosis.

As the continuation of the left ventricle,the left atrium and left ventricle interact and play an important role in the function of the whole heart.At present,there are many techniques to evaluate the atrial structure and function,but the left atrial structure is complex and the myocardium is thin,which brings some challenges to the relevant evaluation.This paper introduces the parameters,precautions and relevant clinical applications in the process of left atrial evaluation from the aspects of myocardial strain and delayed enhancement.

Objective:To explore the clinical application value of DNA image cytometry ploidy analysis (DNA-ICM) in the pathological diagnosis of malignant pleural effusion.Methods:A retrospective case series study was conducted. The clinical data of 101 patients with pleural effusion from October to December 2021 in Shanxi Bethune Hospital were retrospectively analyzed. Liquid-based cytology (LBC) and DNA-ICM were performed on pleural effusion specimens. The sensitivity and specificity of the two methods were compared with the clinical diagnosis, imaging, biopsy, and follow-up results of the patients.Results:Among the pleural effusions of 101 patients, 39 were malignant pleural effusions and 62 were benign pleural effusions. The sensitivity of LBC and DNA-ICM in diagnosing malignant tumor cells in pleural effusions was 74.7% and 94.9%, respectively, and the specificity was 98.4% and 83.9%, respectively; the combination of the two had an increased diagnostic positivity rate compared with that of LBC alone [36.6% (37/101) vs. 28.7% (29/101)]. Seven cases with positive DNA-ICM but negative LBC result were followed up, and 1 case was diagnosed as small cell lung cancer. Conclusions:DNA-ICM can effectively improve the positive cytology detection rate of pleural effusion, and the combined detection of DNA-ICM and LBC can reduce the underdiagnosis rate of cytology, which is of great clinical value in the pathological diagnosis of malignant pleural effusion.

Objective:To investigate the relationship between inherited protein S deficiency (PSD) and cerebral venous sinus thrombosis (CVST) by phenotype and gene mutation analysis of 2 inherited PSD pedigrees with nonsense mutations.Methods:Retrospective analysis of clinical and imaging data of 2 patients diagnosed with CVST who were treated in the Department of Neurology, the First Affiliated Hospital of Wenzhou Medical University in July and October 2023 was carried out. The peripheral blood samples were collected from proband 1 and her family members (3 subjects, 2 generations in total), and proband 2 and his family members (8 subjects of 3 generations in total). Their protein S (PS) activity (PS:A), the content of total PS antigen (TPS:Ag) and free PS antigen (FPS:Ag) were measured for definite diagnosis. Polymerase chain reaction was done in all 15 exons of the active PROS1 gene and its 5′ and 3′ untranslated regions and the amplification products were analyzed by direct sequencing. The results were compared with human PROS1 reference sequences, using Chromas software to find the mutation sites. Results:The proband 1 is a female, and the proband 2 is a male. Both of them had young onset and the clinical presentation of CVST. The PS:A level was reduced to 29% in the proband 1 and reduced to about 35% in her mother; PS:A was reduced to 21%-27% in the proband 2 and his 6 family members; a decline in the same proportion of TPS:Ag and FPS:Ag was found in the 2 probands and their family members, therefore they were primarily diagnosed as typeⅠPSD. Gene analysis showed that the proband 1 and her mother had a nonsense mutation of c.1680T>A in exon 14 (p.Tyr560 *) of the PROS1 gene; the proband 2 and his 6 family members had a nonsense mutation of c.1687C>T in exon 14 (p.Gln563 *) of the PROS1 gene. Conclusion:The reduced protein S levels in PSD patients and their family members may be associated with the p.Tyr560 * and p.Gln563 * nonsense mutations of the PROS1 gene, and the clinical manifestations of CVST in PSD patients may be related to these 2 nonsense mutations.
