Objective To investigate the relationship between sleep disorders and coronary heart disease through big data combined with Mendelian randomization analysis.Methods Data from 2005 to 2018 National Health and Nutrition Examination Survey in the United States were utilized.Logistic regression analysis was employed to evaluate the association between sleep disorders and coronary heart disease,while analyzing relevant influencing factors.A two-sample Mendelian randomization approach was implemented using Genome-Wide Association Studies to establish causal relationships.Results Logistic regression analysis demonstrated a significant association between sleep disorders and coronary heart disease(P＜0.001),with the neutrophil-to-lymphocyte ratio serving as a mediating factor in this relationship(P＜0.001).Mendelian randomization analysis revealed a positive correlation between sleep disorders and coronary heart disease(OR=1.030,95％CI:1.01-1.04).Conclusion Sleep disorders can increase the risk of coronary heart disease by activating inflammatory factors.

A method was developed for determination of dilauryl thiodipropionate(DLTDP)in fried foods by coupling solid-phase extraction(SPE)pretreatment with reverse-phase liquid chromatography-tandem mass spectrometry(RPLC-MS/MS)detection.Samples were extracted with n-hexane as the solvent,purified using a neutral alumina SPE cartridge,and finally analyzed by RPLC-MS/MS.Quantitative analysis was performed using matrix-matched calibration curves combined with an external standard method under optimal experimental conditions.The results showed that DLTDP exhibited good linearity in the range of 2.0-50.0 μg/L,with a correlation coefficient(R2)≥0.999.The limit of detection(LOD)and the limit of quantification(LOQ)of the method were 0.15 mg/kg and 0.5 mg/kg,respectively.The mean recoveries at three fortification levels(0.5,1.0,and 200 mg/kg)in different samples ranged from 84.8%to 96.8%,with the relative standard deviations(RSDs)all less than 8.0%.The developed method was highly sensitive,accurate and reliable,and easy to operate,making it well suited for the routine quantitative analysis of DLTDP in fried foods.

Chronic, unresolved inflammation correlates with persistent hepatic injury and fibrosis, ultimately progressing to hepatocellular carcinoma (HCC). Bisdemethoxycurcumin (BDMC) demonstrates therapeutic potential against HCC, yet its mechanism in preventing hepatic "inflammation-carcinoma transformation" remains incompletely understood. In the current research, clinical HCC specimens underwent analysis using hematoxylin-eosin (H&E) staining and immunohistochemistry (IHC) to evaluate the expression of fibrosis markers, M2 macrophage markers, and CXCL12. In vitro, transforming growth factor-β1 (TGF-β1)-induced LX-2 cells and a co-culture system of LX-2, THP-1, and HCC cells were established. Cell functions underwent assessment through 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), flow cytometry, and Transwell assays. Reverse transcription-quantitative polymerase chain reaction (RT-qPCR), Western blotting and immunofluorescence evaluated the differential expression of molecules. The interaction between β-catenin/TCF4 and CXCL12 was examined using co-immunoprecipitation (Co-IP), dual luciferase, and chromatin immunoprecipitation (ChIP) assays. A DEN-induced rat model was developed to investigate BDMC's role in liver fibrosis-associated HCC (LFAHCC) development in vivo. Our results showed that clinical HCC tissues exhibited elevated fibrosis and enriched M2 macrophages. BDMC delayed liver fibrosis progression to HCC in vivo. BDMC inhibited the inflammatory microenvironment induced by activated hepatic stellate cells (HSCs). Furthermore, BDMC suppressed M2 macrophage-induced fibrosis and HCC cell proliferation and metastasis. Mechanistically, BDMC repressed TCF4/β-catenin complex formation, thereby reducing CXCL12 transcription in LX-2 cells. Moreover, CXCL12 overexpression reversed BDMC's inhibitory effect on macrophage M2 polarization and its mediation of fibrosis, as well as HCC proliferation and metastasis. BDMC significantly suppressed LFAHCC development through CXCL12 in rats. In conclusion, BDMC inhibited LFAHCC progression by reducing M2 macrophage polarization through suppressing β-catenin/TCF4-mediated CXCL12 transcription.

Objective: Uterine cancer (UC) is a major cause of cancer-related deaths among women. This study assesses the global burden of UC from 1990 to 2021. Methods: Data from the Global Burden of Disease 2021 study were used to analyze UC incidence, mortality, and disability-adjusted life years (DALYs) across 204 countries.Age-standardized rates were evaluated by age and Socio-Demographic Index (SDI), with trends forecasted to 2036 using Bayesian models. Results: In 2021, the global incidence of UC reached 473,614 cases (95% uncertainty interval [UI]=4,29916–5,13667), with an age-standardized incidence rate of 5.41 per 100,000 (95% UI=4.90–5.87), showing an upward trend since 1990, particularly in high-SDI regions. However, the mortality rate in high SDI regions exhibited a declining trend, with an estimated annual percentage change (EAPC) of −0.25 (95% confidence interval=−0.42 to −0.08). Although the number of deaths globally has increased, the age-standardized mortality rate has decreased compared to 1990 (EAPC: −0.85). The global age-standardized DALYs also show a downward trend, except in high SDI and low-middle SDI regions. The highest incidence was observed among individuals aged 70–74 in 2021. By 2036, new cases are projected to rise, though incidence, mortality, and DALYs are expected to decline. Conclusion Regional disparities in the global UC burden highlight the need for tailored strategies, especially in low-income countries, to reduce its impact.

Objective:To explore the clinical phenotype and genetic characteristics of four patients with Phelan-McDermid syndrome (PMS) due to variants of SHANK3 gene. Methods:Four patients diagnosed with PMS at Guangzhou Women and Children′s Medical Center Liuzhou Hospital from January 2020 to January 2025 were selected as the study subjects. Clinical data of the patients were collected. Peripheral venous blood samples were collected from each patient for the extraction of genomic DNA, followed by whole-exome sequencing (WES) and validation by Sanger sequencing. Pathogenicity of candidate variants was rated based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), and multiple bioinformatic tools were used to assess the pathogenic effects of the variants. The study was approved by the Ethics Committee of the Guangzhou Women′s and Children′s Medical Center Liuzhou Hospital (Ethics No. 2025-007).Results:All four patients had exhibited language delay and intellectual disability (IQ 35 ~ 65). Some also presented with autism spectrum disorder and schizophrenia, albeit with significant phenotypic heterogeneity. All patients were found to harbor deletions of 22q13.33 region, ranging from 55.46 kb to 112.64 kb, primarily involving the SHANK3 gene. Conclusion:PMS is typically caused by deletions or mutations of the SHANK3 gene. The clinical manifestations are diverse, with developmental delay and intellectual disability being the most common. Accurate diagnosis requires integration of genetic testing and standardized clinical assessment. Genetic screening for suspected patients and at-risk pregnant women is recommended to facilitate their genetic counseling.

[Objective]To investigate pulmonary function levels and associated influencing factors among rural elderly in Guangzhou,to identify high-risk populations for poor pulmonary function,and to reveal the relationship between the influencing factors of pulmonary function.[Methods]We recruited 1 500 residents aged 60 to 94 years from rural area of Conghua District,Guangzhou City using convenience sampling in 2023.Data on demographics,body measurements,medical history and lifestyle were collected via face-to-face questionnaires and physical examination.Meanwhile,expiratory function parameters including forced expiratory volume in one second(FEV1),forced vital capacity(FVC),FEV1/FVC,and the prevalence of airflow obstruction(AFO)were assessed using a portable spirometer.Age and sex distribution of pulmonary function in older adults at 5-year intervals was reported,and risk factors of AFO using multifactorial logistic regression models were analyzed.Furthermore,path analysis was further employed to explore the role of lifestyle in the association between other influencing factors and lung function.[Results]Among the 1 500 participants,the median age was 71 years(67-75),and 44.2%were male.Subjects identified as AFOs were generally older,more likely male,less educated,and had lower rates of moderate to vigorous physical activity(＜1 time/week)and lower lean body mass.Mean FEV1/FVC ratio was(82.0±16.4)%.FEV1/FVC was(79.80±17.58)%in men and(83.66±15.22)%in women.Older age,lower education,male sex and leanness were negatively associated with all pulmonary function outcomes(all P values＜0.05).Path analysis identified that age,gender,marital status,occupation and income may influence pulmonary function indirectly through lifestyle.[Conclusion]Rural elderly in Guangzhou exhibited lower pulmonary function levels,and male sex,non-married status,advanced age,lower education,smoking habits,insufficient engagement in moderate to vigorous physical activity,and lean body type were all associated with worse pulmonary function.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To analyze the factors influencing preoperative anxiety and depression in patients undergoing eye plastic surgery.Methods:A retrospective study was conducted, which included 160 patients awaiting for ocular plastic surgery at the Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine from January to May 2019. Among them, there were 22 males and 138 females, with an average age of (38.6±9.0) years. A one-on-one survey was conducted on enrolled patients using a paper questionnaire. The survey included general patient information, the simplified coping style questionnaire (SCSQ), the Chinese version of the Kessler 10-item questionnaire (Kessler 10), the perceived social support scale (PSSS), and the hospital anxiety and depression scale (HADS). Factors related to anxiety and depression were screened using through univariate analysis and Spearman correlation analysis, and multivariate logistic regression was used to analyze the factors influencing the anxiety and depression.Results:The detection rate for preoperative anxiety in patients undergoing eye plastic surgery was 16.3% (26/160), and that for depression was 25.0% (40/160). A total of 11.3% (18/160) of patients had both anxiety and depression. Multivariate logistic regression analysis showed that positive coping strategies ( OR=0.206, 95% CI: 0.051-0.836), depression ( OR=3.596, 95% CI: 1.068-12.107), and a high Kessler10 scale total score ( OR=1.081, 95% CI: 1.005-1.162) were related to anxiety. A monthly income of 10 000-<20 000 yuan ( OR=0.196, 95% CI: 0.044-0.875), a high total score on the Kessler10 scale ( OR=1.194, 95% CI: 1.085-1.314), and a high total PSSS score ( OR=0.913, 95% CI: 0.870-0.958) were related to depression. Conclusion:Factors affecting anxiety are positive coping strategies, depression, and a high total score on the Kessler 10 scale, while those affecting depression are a monthly income of 10 000-<20 000 yuan, a high total score on the Kessler 10 scale, and a high total score on the PSSS.

A 2-month-old female infant developed fever for 2 days and diarrhea for 1 day. Laboratory tests showed that white blood cell count was 18.8×10 9/L, neutrophil count was 8.3×10 9/L, C-reactive protein was 88.8 mg/L, procalcitonin was 35.9 μg/L, alanine aminotransferase (ALT) was 150 U/L, and aspartate aminotransferase (AST) was 121 U/L. Infectious fever and diarrhea were diagnosed. After 3 days of treatment with ceftriaxone, the diarrhea was improved, but there was still fever. Ceftriaxone was replaced by meropenem (20 mg/kg by intravenous infusion, once per 8 hours). Three days later, the infant′s ALT, AST and white blood cell count returned to normal, but she still experienced recurrent fever (up to 39.0 ℃) and mental fatigue, which was considered to be intracranial infection. The dose of meropenem was doubled (40 mg/kg by intravenous infusion, once per 8 hours), and 3 days later, the infant′s body temperature was normal, but mild yellowish skin occurred, with ALT 1 442 U/L, AST 2 868 U/L, direct bilirubin 20.0 μmol/L, and total bile acid (TBA) 90 μmol/L. Acute liver injury caused by meropenem was considered, the drug was replaced by ceftazidime, and liver-protective treatments such as glutathione and ademetionine were given. After 9 days, the infant′s ALT was 140 U/L, AST was 116 U/L, TBA was 46.3 μmol/L, and yellowish skin disappeared. Two weeks later, her liver function indexes basically returned to normal.
