Although clinical evidence suggests that nonalcoholic fatty liver disease is an established major risk factor for heart failure, it remains unexplored whether sleep disorder-caused hepatic damage contributes to the development of cardiovascular disease (CVD). Here, our findings revealed that sleep fragmentation (SF) displayed notable hepatic detrimental phenotypes, including steatosis and oxidative damage, along with significant abnormalities in cardiac structure and function. All these pathological changes persisted even after sleep recovery for 2 consecutive weeks or more, displaying memory properties. Mechanistically, persistent higher expression of nicotinamide adenine dinucleotide phosphate oxidase 4 (NOX4) in the liver was the key initiator of SF-accelerated damage phenotypes. SF epigenetically controlled the acetylation of histone H3 lysine 27 (H3K27ac) enrichment at the Nox4 promoter and markedly increased Nox4 expression in liver even after sleep recovery. Moreover, fine coordination of the circadian clock and hepatic damage was strictly controlled by BMAL1-dependent Sirtuin 1 (Sirt1) transcription after circadian misalignment. Accordingly, genetic manipulation of liver-specific Nox4 or Sirt1, along with pharmacological intervention targeting NOX4 (GLX351322) or SIRT1 (Resveratrol), could effectively erase the epigenetic modification of Nox4 by reducing the H3K27ac level and ameliorate the progression of liver pathology, thereby counteracting SF-evoked sustained CVD. Collectively, our findings may pave the way for strategies to mitigate myocardial injury from persistent hepatic detrimental memory in diabetic patients.

Objective: To develop a facial image generation method based on a facial color-preserving generative adversarial network (FCP-GAN) that effectively decouples identity features from diagnostic facial complexion characteristics in traditional Chinese medicine (TCM) inspection, thereby addressing the critical challenge of privacy preservation in medical image analysis. Methods: A facial image dataset was constructed from participants at Nanjing University of Chinese Medicine between April 23 and June 10, 2023, using a TCM full-body inspection data acquisition equipment under controlled illumination. The proposed FCP-GAN model was designed to achieve the dual objectives of removing identity features and preserving colors through three key components: (i) a multi-space combination module that comprehensively extracts color attributes from red, green, blue (RGB), hue, saturation, value (HSV), and Lab spaces; (ii) a generator incorporating efficient channel attention (ECA) mechanism to enhance the representation of diagnostically critical color channels; and (iii) a dual-loss function that combines adversarial loss for de-identification with a dedicated color preservation loss. The model was trained and evaluated using a stratified 5-fold cross-validation strategy and evaluated against four baseline generative models: conditional GAN (CGAN), deep convolutional GAN (DCGAN), dual discriminator CGAN (DDCGAN), and medical GAN (MedGAN). Performance was assessed in terms of image quality [peak signal-to-noise ratio (PSNR) and structural similarity (SSIM)], distribution similarity [Fréchet inception distance (FID)], privacy protection (face recognition accuracy), and diagnostic consistency [mean squared error (MSE) and Pearson correlation coefficient (PCC)]. Results: The final analysis included facial images from 216 participants. Compared with baseline models, FCP-GAN achieved superior performance, with PSNR = 31.02 dB and SSIM = 0.908, representing an improvement of 1.21 dB and 0.034 in SSIM over the strongest baseline (MedGAN). The FID value (23.45) was also the lowest among all models, indicating superior distributional similarity to real images. The multi-space feature fusion and the ECA mechanism contributed significantly to these performance gains, as evidenced by ablation studies. The stratified 5-fold cross-validation confirmed the model’s robustness, with results reported as mean ± standard deviation (SD) across all folds. The model effectively protected privacy by reducing face recognition accuracy from 95.2% (original images) to 60.1% (generated images). Critically, it maintained high diagnostic fidelity, as evidenced by a low MSE (< 0.051) and a high PCC (> 0.98) for key TCM facial features between original and generated images. Conclusion The FCP-GAN model provides an effective technical solution for ensuring privacy in TCM diagnostic imaging, successfully having removed identity features while preserving clinically vital facial color features. This study offers significant value for developing intelligent and secure TCM telemedicine systems.

Vertebral refracture following percutaneous vertebral augmentation (PVA) is commonly seen in elderly patients with osteoporotic thoracolumbar compression fractures (OTLCF). It can lead to recurrent pain, loss of vertebral height, progression of kyphosis, and even neurological dysfunction, significantly impairing patients′ quality of life. Current diagnosis and treatment face multiple challenges, including high misdiagnosis rate, difficulty in choosing between surgical and non-surgical treatment options, lack of standardized surgical protocols, interference from intralesional bone cement during procedures, inadequate stability of internal fixation in osteoporotic bone, and suboptimal compliance of anti-osteoporotic therapy. Establishing a standardized diagnostic and therapeutic framework is urgently needed. To standardize the management process and improve outcomes for vertebral refractures after PVA in elderly OTLCF patients, Spinal Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized experts in the field to develop Guideline for the diagnosis and treatment of vertebral refracture after percutaneous vertebral augmentation in elderly patients with osteoporotic thoracolumbar compression fractures ( version 2025), based on current literature and clinical experience, and adhering to principles of scientific rigor and clinical applicability. A total of 11 recommendations were proposed, encompassing diagnosis, treatment, and rehabilitation of vertebral refracture after PVA in elderly patients with OTLCF, aiming to provide a foundation for a standardized management.

Objective:To understand the burden of chronic kidney disease (CKD) and its risk factors in Fujian Province during 1990-2019.Methods:Based on the Global Burden of Disease Study 2019, the incidence rate, mortality rate and disability-adjusted life years (DALYs) of CKD in Fujian from 1990 to 2019 were calculated. An age-period-cohort model was used to estimate the effects of age, period, and cohort on age-standardized incidence rate (ASIR), age-standardized mortality rate (ASMR), and age-standardized DALY rate (ASDR) of CKD. Comparative risk assessment theory was used to calculate the potential attributable DALYs due to risk factors.Results:In 2019, the ASIR of CKD in Fujian exceeded the national average. The ASIR of CKD showed an increasing trend from 1990 to 2019, but the ASMR and ASDR of CKD exhibited decreasing trends during the same period. In 2019, the ASIR of CKD was higher in women than in men, while the ASMR and ASDR were higher in men than in women. Age-period-cohort analysis indicated that ASIR, ASMR, and ASDR of CKD increased with age. The period effect for ASIR decreased first before increase, while the period effect for ASMR and ASDR displayed fluctuating trends. The cohort effect showed an upward trajectory for ASIR, but a stable status before downward trajectories for ASMR and ASDR. Compared with 1990, except the increase in the ASDR of CKD attributed to high BMI and high temperatures, the ASDR of CKD attributed to other risk factors all showed decreases in 2019. However, the ASDR attributed to high sodium intake remained higher compared with the global average.Conclusion:The burden of CKD remains heavy in Fujian, and it is necessary to reduce the attributable risk factors, such as high sodium intake and high BMI, to address this problem.

Objective:To compare the differences in clinical characteristics among the patients at clinical high risk for bipolar disorder(CHR-BD),the patients with bipolar disorder(BD),and the healthy controls(HC)at low risk,and to provide the basis for the diognasis and treatment of CHR-BD.Methods:For the first time,the BD risk criteria and prospective structured assessment tools were jointly used in outpatients aged 16-30 years,and 43 CHR-BD patients were included to ensure the accuracy of the assessment.Meanwhile,33 BD patients and 32 HC subjects were also enrolled.The clinical symptoms,neurocognitive function,and global functional levels of the subjects in the three groups were evaluated using observer-rated and self-rated tools.The CHR-BD and BD groups were combined,and Logistic regression analysis was used to identify the independent influencing factors related to diagnostic status;Pearson or Spearman correlation analysis was used to analyze the correlations between the global functional levels and the symptoms or neurocognitive characteristics of the patients in CHR-BD and BD groups.Results:There were statistically significant differences in the scores of symptom and global functional level scales among HC,CHR-BD,and BD groups(P<0.05).Compared with HC group,the scores of mood symptoms(anxiety,depression,and mania/hypomania),psychotic symptoms,total affective temperament questionnaire scores,and some dimensions(cyclothymic,depressive,irritable,and anxious temperaments)in CHR-BD and BD groups were significantly increased(P<0.001),while the global functional levels were significantly decreased(P<0.001).Compared with BD group,the lowest global functional level score in the past year in CHR-BD group was significantly increased(P=0.022),while the current global functional level score was significantly decreased(P=0.005).No significant differences were observed in neurocognitive function scores among the three groups(P>0.05).The lowest global functional level score in the past year was an independent influencing factor for BD diagnosis[odds ratio(OR)=0.952,95%confidence interval(CI):0.917-0.988,P=0.010].In both CHR-BD and BD patients,the current global functional levels were negatively correlated with depressive(r=-0.417,P=0.005;r=-0.617,P<0.001)and anxiety symptoms(r=-0.360,P=0.018;r=-0.506,P=0.003).In BD patients,the current global functional level was negatively correlated with lifetime manic/hypomanic symptoms(r=-0.360,P=0.039),psychotic symptoms(r=-0.502,P=0.003),and affective temperament scores(r=-0.479,P=0.005),while the lowest global functional level in the past year was negatively correlated with lifetime manic/hypomanic symptoms(r=-0.391,P=0.024).Conclusion:CHR-BD patients share similar mood symptom characteristics with BD patients,and their global functional levels are negatively correlated with depressive and anxiety symptoms.BD patients exhibit worse lowest global functional levels in the past year,and their global functional levels are negatively correlated with manic/hypomanic symptoms.

Objective:To investigate the characteristics of cell subsets in rheumatoid arthritis patients complicated with interstitial lung disease (RA-ILD).Methods:The clinical data of 344 patients with RA admitted to the Affiliated Hospital of Nantong University from June 2022 to November 2023 were analyzed. The patients were categorized into two groups based on the diagnostic criteria of ILD: 120 cases in the RA associated with ILD group (RA-ILD group) were included and 224 cases in the RA without ILD group (RA group), the clinical characteristics were compared between the RA-ILD group and the RA group. The influence factors of RA-ILD were analyzed by univariate and multivariate logistic regression.Results:Compared with RA patients, RA-ILD patients were more common in males, with older age, longer course of disease, and higher smoking rate ( P<0.05). The high titer anti-cyclic citrullinated peptide (CCP) antibody, white blood cells, neutrophil, neutrophil to lymphocyte count ratio, aspartate aminotr-ansferase(AST), creatinine (Cr) and lactate dehydrogenase (LDH) levels in RA-ILD patients were higher than those in RA patients. The triglyceride level was lower than that of RA patients ( P<0.05). The percentage of total T cells in peripheral blood lymphocyte subsets in RA-ILD patients [68.65%(62.22%, 76.78%)] was lower than that in RA patients [71.88%(65.83%, 78.39%)] ( Z=-2.26, P=0.024). The percentage of CD4 +T cells [40.2% (32.10%, 45.23%)] was lower than that of RA patients [46.5% (39.74%, 53.19%)] ( Z=-6.29, P<0.001). CD4 +T cell count [486.50 (324.25, 636.75)cells/μl] was lower than that of RA patients [564.50 (438.25, 752.00)cells/μl] ( Z=-4.50, P<0.001). CD4 +/CD8 + levels [1.86 (1.26, 2.18)] were lower than those of RA patients [2.03 (1.40, 2.94)] ( Z=-2.79, P=0.005). B cell count [127.00 (78.00, 207.25)cells/μl] was lower than that of RA patients [163.50 (91.25, 231.50)cells/μl] ( Z=-2.11, P=0.035), The percentage of NK cells in peripheral blood lymphocyte subsets in RA-ILD patients [19.72%(13.14%, 25.83%)] was higher than that in RA patients [12.55% (8.23%, 17.80%)] ( Z=6.13, P<0.001). NK cell count [182.50 (109.00, 293.75)cells/μl] was higher than that of RA patients [156.00 (89.00, 194.75)cells/μl] ( Z=3.17, P=0.002). The percentage of CD8 +T cells [25.10 %(18.74%, 29.86%)] was higher than that of RA patients [22.27% (17.32%, 29.21%)] ( Z=2.00, P=0.046). Imaging types of RA-ILD patients showed that usual interstitial pneumonia (UIP) was more common, followed by non-specific interstitial pneumonia (NSIP). CD8 + T cell count and percentage expression level in UIP were higher than NSIP, and CD4 +/CD8 + expression level was lower than NSIP ( P<0.05). Multivariate logistic regression analysis of indicators with statistical differences were male gender [ OR(95% CI)=2.888 (1.556, 5.360), P=0.001], age [ OR(95% CI)=1.065 (1.033, 1.098), P<0.001], disease duration [ OR(95% CI)=1.004 (1.001, 1.007), P=0.013], high titer anti-CCP antibody [ OR(95% CI)=2.764 (1.214, 6.292), P=0.015], LDH [ OR(95% CI)=1.006 (1.002, 1.009), P=0.001], CD4 +T cell percentage [ OR(95% CI)=0.964 (0.929, 1.000), P=0.049], CD4 +T cell count [ OR(95% CI)=0.998 (0.996, 1.000), P=0.011] and NK cell count [ OR(95% CI)=1.004 (1.001, 1.007), P=0.003]. These indicators were correlated factors for RA-ILD. Conclusion:Male patients with older age, history of smoking and a long disease course are more likely to develop ILD. Male gender with older, long disease course, high titer anti-CCP antibody, increased LDH and NK cell count, CD4 +T cell percentage and decreased CD4 +T cell count are correlation factors for RA-ILD, which may help RA patients to recognize ILD early.

Objective:To investigate pediatric colonoscopy procedures and the associated changes in the disease spectrum.Methods:The clinical data of 1 087 children who underwent pediatric colonoscopy at the Second Affiliated Hospital of Nanjing Medical University and Yili Prefecture Friendship Hospital Affiliated to Nanjing Medical University from January 2012 to December 2022 were retrospectively collected. Patients were divided into 0-3 ( n=165), 4-6 ( n=307), 7-10 ( n=275) and 11-14 ( n=340) years groups according to their age, and also divided into two time periods according to the examination time point, 2012-2017 ( n=302) and 2018-2022 ( n=785) groups. Indicators that were observed and analyzed included the primary reasons for colonoscopy, types and proportions of abnormalities, distribution of cases and symptoms by period and age group, and disease diagnosis and treatment before and after colonoscopy. Results:A total of 1 238 colonoscopies were completed in 1 087 children. Blood in the stool was the most common cause (337/1 087, 31.00%). The most abnormalities were found in intestinal polyps (190/1 087, 17.48%) and inflammatory bowel disease (IBD) (181/1 087, 16.65%), as well as in 95 cases (95/1 087, 8.74%) who were confirmed autism and requested colonoscopy placement for fecal microbiota transplantation (FMT). There were differences in case distribution and symptoms among different age groups: polyps were most common in the 0-3 years group (75/165, 45.45%), and IBD was most common in the 11-14 years group (97/340, 28.53%). Compared with 2012-2017, during 2018-2022, the proportion of colonoscopies for polyps in children decreased [from 49.67% (150/302) to 5.10% (40/785), P<0.001], while the proportion for IBD increased [from 12.25% (37/302) to 18.34% (144/785), P=0.016], and autism requiring colonoscopic duct placement for FMT increased [from 2.32% (7/302) to 11.21% (88/785), P<0.001]. Conclusion:Pediatric colonoscopy plays an important role in the diagnosis and treatment of pediatric diseases. With the increasing clinical application demands, diversified procedures such as pre-FMT colonoscopic duct placement are becoming important directions for the future development of pediatric colonoscopy.
