Objective To analyze changes in sleep,mood state,and brain function in healthy populations living in near-sea-level environments before and after exposure to high-altitude environment,and to explore the correlations between regional brain functional changes and variations in sleep and mood states.Methods A total of 45 healthy volunteers were enrolled.The participants came from regions of near-sea-level altitudes and were exposed to the high-altitude environment for a short period of time.The Pittsburgh Sleep Quality Index(PSQI),Zung Self-Rating Depression Scale(SDS),Patient Health Questionnaire-9(PHQ-9),Zung Self-Rating Anxiety Scale(SAS),and Generalized Anxiety Disorder-7(GAD-7)were administered to assess sleep quality as well as depressive and anxiety symptoms at 4 time points—prior to high-altitude exposure,immediately after exposure,one month after returning to low-altitude regions,and three months after returning to low-altitude regions.Resting-state functional magnetic resonance imaging(rs-fMRI)data were collected before and after high-altitude exposure,and regional brain functional parameters,including the amplitude of low-frequency fluctuations(ALFF)and functional connectivity strength,were analyzed.Statistical analyses were performed,including a linear mixed-effects model to evaluate longitudinal changes in scale scores,paired-sample t-tests to compare brain function differences before and after exposure,and Pearson correlation analyses to examine the relationship between brain functional changes and alterations in sleep and mood states.Results Compared with the pre-exposure findings,the participants exhibited significantly increased PSQI scores(8.89±4.41 vs.5.08±2.69,P<0.05)and PHQ-9 scores(3.60±4.19 vs.1.54±2.30,P<0.05)immediately after high-altitude exposure.One month after returning to the low-altitude environment,both sleep and depression scores decreased relative to the findings immediately after exposure(PSQI:3.88±2.13 vs.8.89±4.41,P<0.05;PHQ-9:1.50±2.25 vs.3.60±4.19,P<0.05)and showed no statistically significant difference compared with the pre-exposure findings(P>0.05).Three months after returning to near-sea-level environment,sleep,depression,and anxiety scores were all reduced compared with the findings immediately after exposure(PSQI:3.76±2.31 vs.8.89±4.41,P<0.05;PHQ-9:1.24±2.13 vs.3.60±4.19,P<0.05;SAS:23.84±5.93 vs.27.93±7.05,P<0.05),also showing no significant difference compared with the pre-exposure levels(P>0.05).Brain function analysis revealed that,relative to the pre-exposure levels,ALFF in the bilateral superior temporal gyrus,insula,and dorsolateral prefrontal cortex(DLPFC)increased after high-altitude exposure(P<0.05),and that functional connectivity strength in the DLPFC was also elevated(P<0.05).Furthermore,changes in DLPFC functional connectivity strength were positively correlated with changes in sleep and mood scores(P<0.05).Conclusion High-altitude exposure has a significant impact on the sleep,mood states,and brain function of populations from near-sea-level regions,and DLPFC,in particular,is closely associated with changes in sleep and mood states.The findings of this study provide a theoretical basis for health management and intervention strategies in high-altitude environments.

BackgroundChronic insomnia is characterized by a prolonged and recurrent course. The efficacy of repeated transcranial magnetic stimulation （rTMS） as a physical therapy method to improve sleep quality remains inadequately supported by evidence， particularly regarding its relationship with personality traits. ObjectiveTo explore the efficacy and influencing factors of rTMS in the treatment of chronic insomnia， and to provide insights into its therapeutic potential. MethodA total of 46 patients who met the diagnostic criteria for chronic insomnia according to the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5）， and were treated at the Third Hospital of Mianyang from September 2022 to September 2023 were selected. Prior to treatment， participants underwent assessments using the Eysenck Personality Questionnaire （EPQ）， Hamilton Depression Scale-17 item （HAMD-17） and Hamilton Anxiety Scale （HAMA）. The Pittsburgh Sleep Quality Index （PSQI） was used to assess sleep quality before treatment， at the end of the second week of treatment and one week post-treatment. ResultsAt the end of the second week of treatment， patients exhibited significantly improved total PSQI score and subscale scores related to subjective sleep quality， sleep latency， sleep duration， sleep efficiency， sleep disturbance and daytime dysfunction （t=4.755~13.361， P<0.01）， with 24 cases （54.35%） showing effective treatment outcomes. Multiple linear regression analysis showed that introverted and extroverted personality traits contributed significantly to the regression equation （B=0.317， P<0.01）， explaining 29.90% of the total variation （R²=0.299）. ConclusionrTMS treatment may effectively improve the sleep quality of patients with chronic insomnia， with its therapeutic effect appearing to associated with introverted and extroverted personality traits. ［Funded by National Natural Science Project of China （number， 82372080）］

Objective To observe the expression of Galectin-3 in peritoneal dialysis (PD) fluid in patients with different dialysis ages, and to conduct correlation analysis with vascular endothelial growth factor (VEGF) , fi-bronectin (FN) and related clinical indicators.Methods A total of 109 PD patients who were regularly followed up in the department of nephrology were divided into four groups according to different peritoneal dialysis ages.The concentrations of Galectin-3, VEGF and FN were determined by enzyme-linked immunosorbent assay.The expres-sion of Galectin-3 in peritoneal dialysate of the 4 groups was compared, the correlation with VEGF, FN and clinical related indexes was analyzed, and the correlation was analyzed by Spearman test.Results The concentration of VEGF in peritoneal dialysis patients in group D significantly increased (P<0.05) .Galectin-3 expression levels were positively correlated with VEGF (r =0.358 , P =0.022) , but not significantly correlated with FN (r =0.121, P=0.452).Galectin-3 was positively correlated with clinical indicators parathyroid hormone (PTH) (r=0.201, P=0.037), C-reactive protein (CRP) (r=0.357, P<0.001), left ventricular posterior wall dimensions (LVPWD) (r=0.213, P=0.026), and negatively correlated with clinical indicators total cholesterol (TC) (r=-0.316, P=0.001).Conclusion The concentration of Galectin-3 in the dialysate of long-term peritoneal dialy-sis patients is significantly elevated, indicating that the expression of galectin-3 increases with the extension of peri-toneal dialysis time, suggesting that the detection of galectin-3 levels may be helpful for the evaluation of early peri-toneal fibrosis.The positive correlation with VEGF may suggest its role in promoting peritoneal angiogenesis and fi-brosis.Moreover, it is positively correlated with clinical indicators PTH, CRP and LVPWD, suggesting that it has certain clinical guiding significance on microinflammatory state and myocardial remodeling.

Objective To assess the impact of statins combined with sorafenib(SRF)therapy on survival outcomes in patients with metastatic renal cell carcinoma(mRCC).Methods Clinical data of mRCC patients treated in the 908th Hospital of the Joint Security Force from November 2019 to November 2023 were retrospectively analyzed.They were categorized into statin group and non-statin group according to whether they used statins or not,and the differences in the primary endpoint of overall survival(OS),secondary endpoints of progression-free survival(PFS),objective response rate(ORR),and disease control rate(DCR)were compared between the two groups.Results A total of 80 patients were included in the study,with 27 in the statin group and 53 in the non-statin group.There were no statistically significant differences in partial remission,stable disease,disease progression,and DCR between the two groups(P＞0.05);complete remission and ORR were significantly higher in the statin group than in the non-statin group(P＜0.05).Kaplan-Meier analysis showed that,compared with the non-statin group,the median PFS and OS of the statin group were prolonged,and the difference in median PFS between the two groups was statistically significant(P＜0.05).In terms of safety,the incidence of other adverse events was similar in both groups(P＞0.05).Conclusion Statins combined with SRF treatment regimen can improve ORR and DCR and prolong median PFS and OS in patients with mRCC.

Objective To compare the therapeutic effect of lauromacrogol combined with different concentrations of pingyangmycin in the treatment of low-flow venous malformations of limbs.Methods A total of 83 child patients with low-flow venous malformations of limb,who were admitted to the Xi'an Thoracic Surgery/Tumor(Hemangioma)Intervention Center of China between 1 January 2021 and 1 June 2022,were enrolled in this study.The child patients were randomly divided into group A(n=42)and group B(n=41).Under imaging guidance,lauromacrogol mixed together with pingyangmycin(2 mg/mL in group A,and 1 mg/mL in group B)was slowly injected into the cavity of venous malformations until the drug mixture filled the tumor cavity.The curative effect,number of treatments within 6 months,and the incidence of adverse reactions were compared between the two groups.Results Successful interventional sclerotherapy was accomplished in all the 83 child patients of both groups.During the follow-up period of 6 months,the effective rate in group A and group B was 92.9％(39/42)and 87.8％(36/41)respectively.A total of 88 interventional procedures were performed in group A and 137 interventional procedures in group B,the difference between the two groups was statistically significant(x2=3.282,P=0.047).Adverse reactions occurred in 10 child patients of group A and in 8 child patients of group B,the difference between the two groups was not statistically significant(P=0.709).Conclusion In treating low-flow venous malformations of limbs,the use of higher concentration pingyangmycin and lauromacrogol mixture has quite the same curative effect and incidence of adverse effects as the use of lower concentration pingyangmycin and lauromacrogol mixture,although the use of higher concentration pingyangmycin and lauromacrogol mixture can reduce the number of treatments in child patients.(J Intervent Radiol,2024,33:483-487)

In order to address the issues of spatial induction bias and lack of effective representation of global contextual information in colon polyp image segmentation, which lead to the loss of edge details and mis-segmentation of lesion areas, a colon polyp segmentation method that combines Transformer and cross-level phase-awareness is proposed. The method started from the perspective of global feature transformation, and used a hierarchical Transformer encoder to extract semantic information and spatial details of lesion areas layer by layer. Secondly, a phase-aware fusion module (PAFM) was designed to capture cross-level interaction information and effectively aggregate multi-scale contextual information. Thirdly, a position oriented functional module (POF) was designed to effectively integrate global and local feature information, fill in semantic gaps, and suppress background noise. Fourthly, a residual axis reverse attention module (RA-IA) was used to improve the network's ability to recognize edge pixels. The proposed method was experimentally tested on public datasets CVC-ClinicDB, Kvasir, CVC-ColonDB, and EITS, with Dice similarity coefficients of 94.04%, 92.04%, 80.78%, and 76.80%, respectively, and mean intersection over union of 89.31%, 86.81%, 73.55%, and 69.10%, respectively. The simulation experimental results show that the proposed method can effectively segment colon polyp images, providing a new window for the diagnosis of colon polyps.

AIM:From the perspective of regulating mitochondrial complex I activity by DJ-1 protein,this study aims to explore the mechanism of DJ-1-mediated resveratrol(RES)preconditioning in protecting against oxidative stress injury induced by myocardial ischemia-reperfusion(I/R)in rats.METHODS:After intramyocardial injection of lentivirus carrying DJ-1 shRNA(sh-DJ-1)or negative control(NC)shRNA,the myocardial I/R model was constructed by ligating the left anterior descending branch of the rat coronary artery.Sprague-Dawley(SD)rats were randomly divided in-to 6 groups:sham group,I/R group,RES+I/R group,NC+RES+I/R group,sh-DJ-1+RES+I/R group,and IACS-010759(mitochondrial complex I inhibitor)+RES+I/R group,with 10 rats in each group.The rats in RES treatment groups were given RES(20 mg/kg)via gavage for 7 d prior to the myocardial I/R modeling,once daily.Moreover,the rats in sham and I/R groups received an equivalent volume of normal saline via gavage.Myocardial infarction area and cardiac function were assessed by TTC staining and echocardiography,respectively.The MitoSOX fluorescent probe was used to detect levels of mitochondrial reactive oxygen species(ROS)in the myocardium.The levels of malondialdehyde(MDA),superoxide dis-mutase(SOD)and lactate dehydrogenase(LDH)in the serum were detected using kits.Western blot and co-immunopre-cipitation assays were used to observe the interaction between DJ-1 and the two subunits,ND-1 and NDUFA4,of the mito-chondrial complex I.RESULTS:Compared with I/R group,RES pretreatment significantly reduced the myocardial in-farction area,mitochondrial ROS levels,serum LDH activity,and serum MDA content(P＜0.01).It also elevated left ventricular ejection fraction,left ventricular fractional shortening and serum SOD activity(P＜0.01).Pretreatment with RES increased the expression and mitochondrial translocation of DJ-1(P＜0.01),promoted the interaction between DJ-1 and ND-1/NDUFA4,which in turn protected the activity of mitochondrial complex I(P＜0.01).However,when the ex-pression of DJ-1 was suppressed,the protective effects of RES against myocardial I/R injury were significantly inhibited compared with RES+I/R group(P＜0.05 or P＜0.01).CONCLUSION:Pretreatment with RES increases the expression and mitochondrial translocation of DJ-1,and facilitates the interaction of DJ-1 with ND1 and NDUFA4 subunits of mito-chondrial complex I,thus preserving the activity of mitochondrial complex I and attenuating myocardial I/R-induced oxida-tive stress damage.

In this study, we cloned the complete coding sequence (CDS) of chicken foxp3 (chfoxp3) gene, analyzed its structure, and investigated its expression profile in different chicken tissues. To be specific, chfoxp3 was cloned from the splenic tissue of 50-day-old specific-pathogen-free chickens, and analyzed by using online bioinformatics tools or software. The expression profiles of the chfoxp3 gene in different chicken tissues were detected by quantitative real-time PCR (qRT-PCR). The results indicated that the chfoxp3 gene contains an 882-bp open reading frame, encoding 293 amino acids hydrophilic protein with a molecular weight of 33.44 kDa. The chFoxp3 protein has a forkhead domain and carries a nuclear localization signal, which is typical in the Fox transcription factor family. The secondary structure of chFoxp3 consists of α-helix (29.35%), extended chain (10.92%), β-turn (5.12%) and random coil (54.61%). The expression of chfoxp3 varied in different tissues. The expression levels of chfoxp3 in chicken heart and pancreas were higher than in spleen, bursa of Fabricius, thymus, and other immune organs (P < 0.01), which was quite different from that of mammals. Phylogenetic tree analysis showed that chFoxp3 belonged to the same clade as other wild birds did, but was far different from that of mammals. These results may facilitate further research on the role of chFoxp3 in immune regulation.

Objective:To investigate the correlation between amide proton transfer-weighted (APTw) values and Ki-67 labeling index of cervical squamous cell carcinoma.Methods:From October 2017 to December 2018, 24 patients with cervical squamous cell carcinoma [International Federation of Gynecology and Obstetrics (FIGO) stage Ⅰ-Ⅲ] were prospectively enrolled in Peking Union Medical College Hospital and underwent pelvic morphological MRI on a 3.0 T MR scanner, including three-dimensional turbo-spin-echo APTw imaging and DWI. The maximum diameters of the lesions, APTw values and ADC values on the slice with the maximum diameter of the lesion were independently measured by two radiologists. The ICC was computed to evaluate the inter-observer consistency. Ki-67 immunohistochemical expression status was assessed by one pathologist. The Pearson correlation analysis was performed between the APTw values, maximum diameters, ADC values and Ki-67 labeling index.Results:The APTw values of cervical squamous cell carcinoma were (2.9±0.5)%. Inter-observer ICC was 0.972 (95%CI 0.937-0.988). The APTw values were positively moderately correlated with Ki-67 labeling index [(61.9±18.7)%, r=0.532, P=0.008]. The maximum diameters of the lesions were (28.7±10.6) mm. The mean ADC values were (0.998±0.217)×10 -3 mm 2/s. No correlations were found between maximum diameters, ADC values and Ki-67 labeling index ( r=0.038, P=0.859; r=0.238, P=0.263). Conclusion:APTw values can partially reveal the proliferation status of cervical squamous cell carcinoma.

Objective: To explore the application value of 3.0 T MultiVane XD (MVXD) technique in female patients with uterine adenomyosis and fibroids. Methods: Patients diagnosed with uterine fibroids with ultrasound and suspected of adenomyosis were involved prospectively from March to May 2018, 3.0 T pelvic MRI examinations were performed during peri-ovulatory period. Axialconventional turbo spin echo (TSE) T₂WI, axial MVXD T₂WI, sagittal conventional TSE T₂WI and MVXD sagittal T₂WI were acquired. Two observers rated those 4 series in the aspects of sharpness of uterine border, motion artifacts, identification capability of lesions, confidence of diagnosis and overall image quality. Cohen Kappa analysis was used to evaluate the consistency of scores between 2 observers. Scores of TSE T₂WI and MVXD T₂WI qualities were compared using Wilcoxon matched-pairs signed-ranks test. Results: Twenty patients were enrolled. Axial conventional TSE T₂WI, axial MVXD T₂WI were aquired on all of them. Sagittal conventional TSE T₂WI, sagittal MVXD T₂WI were aquired on 19 among them. Nine patients had only obvious adenomyosis, 6 had only uterinefibroids, and 5 had adenomyosis and uterine fibroids. Compared to conventional TSE technique, scores of two observers in the sharpness of uterine border, motion artifacts, and overall image quality is higher by MVXD with significant difference (P<0.05). The Kappa values for image quality scores of two observers ranged from 0.615 to 0.971, the agreement was good or very good. Conclusion Applying MVXD T₂WI technique to patients with uterine fibroids and adenomyosiscould improve image quality, without sacrificing the ability to recognize and diagnose lesions, compared to conventional TSE T₂WI technique.
