Objective: To explore the association between takeout fast foods and sugar sweetened beverage consumption with co-occurrence of anxiety and depressive symptoms among first year junior high school students in Yunnan Province, so as to provide theoretical basis for the prevention of anxiety and depressive symptoms co-occurrence among adolescents. Methods: A random cluster sampling involving 8 500 first year junior high school students in 11 counties in Yunnan Province was conducted by a questionnaire survey from October to December 2022. The Depression Anxiety Stress Scale-21 (DASS-21) was applied to assess anxiety and depressive symptoms in first year junior high school students. Chi-square test was used to compare the anxiety-depression co-occurrence symptoms of first year junior high school students with different demographic characteristics. The association between takeout fast foods and sugar sweetened beverage consumption with co-occurrence of anxiety and depressive symptoms of adolescents was analyzed by binary Logistic regression models. Results: The detection rate of co-occurrence of anxiety and depression symptoms among first year junior high school students in Yunnan Province was 26.92%. After controlling for demographic variables and other confounders, takeout fast foods and sugar sweetened beverage consumption( OR=1.50, 95%CI =1.27-1.77) was associated with anxiety-depression co-occurrence symptoms among first year junior high school students in Yunnan Province ( P <0.01). Stratified analysis showed that both Han ( OR=1.37, 95%CI =1.07-1.77) and ethnic minorities ( OR=1.60, 95%CI =1.29-2.00) exhibited statistically significant associations between takeout fast foods and sugar sweetened beverage consumption with co-occurrence of anxiety and depressive symptoms(both P <0.05). Conclusions Takeout fast foods and sugar sweetened beverage consumption increases the risk of co-occurrence of anxiety and depressive symptoms among first year junior high school students in Yunnan Province. It is recommended to strengthen guidance on the consumption of such products among junior high school students to prevent co-occurrence of anxiety and depressive symptoms.

PURPOSE: Although there are significant differences between China and the United States (US) in trauma medical services, there has been no direct comparative research on the epidemiological data of trauma centers between the 2 countries. This study aims to fill this research gap by directly comparing trauma centers in China and the US, providing valuable data and insights for the development of trauma centers in both countries, promoting academic exchange and cooperation internationally, and enhancing the level of global trauma medical care. METHODS: This is a multicenter retrospective descriptive study. Data were collected for trauma patients with an injury severity score ≥16 treated from September 2013 to September 2019 at 2 hospital trauma centers in these 2 countries. Detailed clinical data (including injury mechanism, age, injury site, injury severity score, pre-hospital transport time, whether blood transfusion was performed, whether resuscitative thoracotomy was conducted, hospital and intensive care unit stay duration, the number of organ donor patients, mortality rates, and costs) were meticulously compiled and retrospectively analyzed to identify differences between the 2 trauma centers. The comparison was conducted using SPSS 23 software. Continuous variables are reported as median (Q₁, Q₃), and Mann Whitney U test is used to compare the median of continuous variables. Use clinically relevant critical points to classify continuous variables, with categorical variables represented as n (%), and comparisons were made between the 2 groups using the χ² test or Fisher's exact test. Statistical significance was defined as a 2-sided p < 0.05. RESULTS: These results point to significant differences in trauma center capacity, pre-hospital transport times, treatment procedures, hospital stay duration, mortality rates, and costs between the 2 centers. The volume of patients in trauma centers is less in China (2465 vs. 5288). Pre-hospital transport time was notably longer in China (180 min vs. 14 min), and the rate of emergency blood transfusions was lower in China (18.4% vs. 50.6%), Emergency thoracotomy was not performed in China but was conducted in 9.8% of cases in the US. Hospitalization costs were significantly lower in China than in the US ($5847 vs. $75,671). CONCLUSION There are clear differences in trauma center capacity (number of patients treated), pre-hospital transport time, age distribution of injured patients, injury mechanisms, injury sites, whether emergency thoracotomy is performed, hospital costs, and length of stay between the 2 trauma centers in China and America. Understanding these differences can help us further recognize the characteristics of Eastern and Western trauma patients.

OBJECTIVES: To analyze the potential causal relationship between gut microbiota and food allergy (FA) using two-sample Mendelian randomization (MR) methods. METHODS: Data from genome-wide association studies on gut microbiota and FA were utilized. MR analysis was conducted employing inverse variance weighting, MR-Egger regression, and weighted median methods to assess the causal relationship between gut microbiota and FA. Cochrane's Q test was used to evaluate heterogeneity of instrumental variables, MR-PRESSO analysis was conducted to test for outliers and pleiotropy, and MR-Egger regression was employed to assess horizontal pleiotropy. The "leave-one-out" method was used to evaluate the impact of removing individual single nucleotide polymorphisms on the causal relationship. RESULTS: Inverse variance weighting analysis revealed that the phylum Verrucomicrobia, family Verrucomicrobiaceae, order Verrucomicrobiales, genus Ruminococcaceae UCG013, and genus Akkermansia were negatively associated with FA (P<0.05). Sensitivity analyses confirmed the reliability of the findings, indicating no heterogeneity or pleiotropy present. CONCLUSIONS There is a causal relationship between gut microbiota and FA, with Verrucomicrobia, Verrucomicrobiaceae, Verrucomicrobiales, Ruminococcaceae UCG013, and Akkermansia potentially reducing the risk of developing FA. These findings provide potential targets for the treatment and prevention of FA; however, further research is needed to explore the specific mechanisms by which the microbiota influence FA.

The innate immune sensor NLRP3 inflammasome overactivation is involved in the pathogenesis of ulcerative colitis. PGAM5 is a mitochondrial phosphatase involved in NLRP3 inflammasome activation in macrophages. However, the role of PGAM5 in ulcerative colitis and the mechanisms underlying PGAM5 regulating NLRP3 activity remain unknown. Here, we show that PGAM5 deficiency ameliorates dextran sodium sulfate (DSS)-induced colitis in mice via suppressing NLRP3 inflammasome activation. By combining APEX2-based proximity labeling focused on PGAM5 with quantitative proteomics, we identify NEK7 as the new binding partner of PGAM5 to promote NLRP3 inflammasome assembly and activation in a PGAM5 phosphatase activity-independent manner upon inflammasome induction. Interfering with PGAM5-NEK7 interaction by punicalagin inhibits the activation of the NLRP3 inflammasome in macrophages and ameliorates DSS-induced colitis in mice. Altogether, our data demonstrate the PGAM5-NEK7 interaction in macrophages for NLRP3 inflammasome activation and further provide a promising therapeutic strategy for ulcerative colitis by blocking the PGAM5-NEK7 interaction.

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 cost-effectiveness of abemaciclib， palbociclib and ribociclib combined with aromatase inhibitors （AI） in first-line treatment of hormone receptor-positive （HR+） advanced breast cancer from the perspective of Chinese medical system. METHODS The 20-year disease course of the patients was simulated by the partitioned survival model， and the simulation period was determined to be 4 weeks， the model output was the total cost and quality-adjusted life year （QALY）， the cost and effect were discounted at a discount rate of 5%. A network meta-analysis was constructed by systematically searching relevant clinical trials to obtain the efficacy parameters of abemaciclib， palbociclib and ribociclib combined with AI. Survival fitting and extrapolation were performed based on the survival curve of the placebo group in MONALEESA-2 trial. Cost-effectiveness was assessed by incremental cost-effectiveness ratio （ICER） and incremental net monetary benefit （INMB）， with a willingness-to-pay threshold of 3 times China’s per capita gross domestic product （GDP） in 2023； one-way sensitivity analysis and probability sensitivity analysis were used to detect the influence of parameters on the results and the robustness of the incremental analysis results. RESULTS In the 20-year simulation， compared with palbociclib+AI scheme， the ICER of ribociclib+AI scheme was 58 558.38 yuan/QALY and the INMB was 62 988.20 yuan. Compared with ribociclib+AI scheme， the ICER of abemaciclib+AI scheme was 264 928.34 yuan/QALY and the INMB was 344.84 yuan. One-way sensitivity analysis showed that the incremental analysis results of abemaciclib+AI scheme compared to ribociclib+AI scheme were not robust. Probabilistic sensitivity analysis confirmed that the probability of ribociclib+AI scheme becoming the most economical was the highest when the threshold was 1-3 times China’s per capita GDP in 2023. CONCLUSIONS Ribociclib+AI scheme is more likely to be the most economical first-line treatment than abemaciclib+AI scheme and palbociclib+AI scheme in Chinese patients with HR+ advanced breast cancer when threshold is 1-3 times China’s per capita GDP in 2023.

Objective:To study the clinical and immunological features of two case of rare antisynthetase syndrome (ASS), so as to improve the level of diagnosis and treatment.Methods:Two cases with rare antisynthetase syndrome admitted to the First Affiliated Hospital of Zhengzhou University from July 2020 to August 2022 were collected.Results:The two rare ASS were anti-Zo antibody and anti-Ha antibody positive patients, both of which had interstitial lung disease (ILD) as the main clinical manifestation and positive anti-Ro52 antibody. Two rare antisynthetase autoantibodies manifested cytoplasmic ANA indirect immunofluorescence (IIF) staining pattern, but it is different from the cytoplasmic dense speckled pattern of several common ASS antibodies. After treatment with glucocorticoids and immunosuppressants, case 1 died of respiratory failure due to a long course of disease and late diagnosis, the lung lesions of case 2 improved significantly.Conclusion:When encountering the cytoplasmic ANA fluorescent pattern in ILD patients, especially with anti-Ro52 antibody, it is necessary to screen more myositis specific antibodies to rule out the possibility of rare ASS.

Objective:To investigate the distribution of potential suitable habitats for Ixodes persulcatus in Heilongjiang Province during different climatic periods. Methods:The geographical location data of Ixodes persulcatus in Heilongjiang Province from 1980 to 2023 were collected through literature search and field ecological investigation. The environmental factor variables were downloaded from the WorldClim website and the Resource and Environmental Science and Data Platform. A combination of SDMtune, ENMTools packages, and the maximum entropy (MaxEnt) model were used to predict the potential habitats of Ixodes persulcatus in Heilongjiang Province during different climatic periods and determine its dominant environmental factors. Among them, the time range of historical climatic period data was 1970 - 2000. The future climatic period data (2021 - 2040, 2041 - 2060) were selected as the low forcing scenario (SSP126 scenario) of the shared socioeconomic pathways (SSP) in the Beijing Climate Center - Climate System Model version 2-Medium Resolution, to simulate the impact of global warming on the distribution of potential habitats for Ixodes persulcatus in Heilongjiang Province. Results:A total of 83 geographical distribution sites of Ixodes persulcatus in Heilongjiang Province were obtained. After screening, 10 environmental factors were included in the MaxEnt model. Among them, the cumulative contribution percentage of annual precipitation, average annual temperature, and vegetation type was 67.3%. Compared with historical climatic period, the total potential habitats of Ixodes persulcatus in Heilongjiang Province increased from 29.81 × 10 4 km 2 to 32.24 × 10 4 km 2 in 2041 - 2060. The center of potential habitats moved to 47.75° N, and 128.66° E, with a northwest offset of 126.07° and a migration distance of 45.83 km. Conclusion:With global climate warming, the total potential habitats of Ixodes persulcatus in Heilongjiang Province has increased, showing an overall trend of migration to the northwest.
