Objective:To investigate the current status of attitudes toward seeking professional psychological help in patients after gastrointestinal tumor surgery and to analyze their influencing factors.Methods:Convenience sampling was used to select 153 patients who underwent surgery at the Gastrointestinal Tumor Center of Peking University Cancer Hospital as study subjects. General Information Questionnaire, Chinese version of Attitude Seeking Professional Psychological Help Scale-Short Form (ATSPPH-SF) , Simplified Coping Style Questionnaire, and General Self-Efficacy Scale were used to conduct the survey. Spearman correlation was used to analyze the correlation between attitudes toward seeking professional psychological help and coping styles and self-efficacy in patients after gastrointestinal tumor surgery. Multiple linear regression was used to explore the factors influencing attitudes toward seeking professional psychological help in patients after gastrointestinal tumor surgery. A total of 153 questionnaires were distributed and 149 valid questionnaires were recovered, with a valid recovery rate of 97.39% (149/153) .Results:The total ATSPPH-SF score of 149 patients with gastrointestinal tumor surgery was [16.00 (13.00, 19.00) ]. Multiple linear regression analysis showed that work status, seeking professional psychological help, and coping styles were the influencing factors on the attitude toward seeking professional psychological help in patients after gastrointestinal tumor surgery ( P<0.05) . Conclusions:The level of attitudes toward seeking professional psychological help in patients after gastrointestinal tumor surgery is low and is influenced by a number of factors. Healthcare professionals can carry out individualized interventions for different patients, enhance absentee patients' disease knowledge, sense of self-worth, and encourage them to carry out professional psychological counseling and establish a positive coping style, so as to increase the initiative of patients to seek professional psychological help.

Objective:To investigate the effect of mild moxibustion on transient receptor potential vanilloid type 1(TRPV1)channel expression in primary dysmenorrhea(PD)rats and explore its mechanism in alleviating central pain sensitization.Methods:Thirty-two female non-pregnant Wistar rats were randomized into a blank group,a model group,a mild moxibustion group,and a capsazepine group,with 8 rats in each group.Except for the blank group,the other three groups used estradiol benzoate,ice-water bath,and oxytocin to establish the rat PD model of cold-dampness stagnation pattern.The interventions began on day 1 of modeling,once a day,and lasted 10 d.The mild moxibustion group received mild moxibustion at Shenque(CV8)and Guanyuan(CV4),20 min/time;in the capsazepine group,capsazepine was injected at a dose of 2 mg/(kg·bw).The abdominal pain threshold was measured 10-30 min after oxytocin injection on day 11;enzyme-linked immunosorbent assay was used to detect serum prostaglandin F2α(PGF2α)level;the expression of TRPV1,cluster of differentiation 11B(CD11B),and proto-oncogene c-Fos in the spinal dorsal horn and hypothalamus was detected by immunofluorescence and Western blotting.Results:Compared to the blank group,the model group showed a decreased pain threshold(P<0.05)and an increased serum PGF2α level with elevated TRPV1,CD11B,and c-Fos protein expression in the spinal dorsal horn and hypothalamus(P<0.05).Compared to the model group,both the mild moxibustion group and capsazepine group showed significantly increased pain thresholds(P<0.05),along with decreased serum PGF2α levels and reduced protein expression levels of TRPV1,CD11B,and c-Fos in the spinal dorsal horn and hypothalamus(P<0.05).Rat pain threshold in the capsazepine group was higher than that in the mild moxibustion group(P<0.05).Serum PGF2α level,the expression levels of CD11B and c-Fos proteins in the spinal dorsal horn,as well as TRPV1,CD11B,and c-Fos proteins in the hypothalamus of the capsazepine group were lower than those in the mild moxibustion group(P<0.05).Conclusion:Mild moxibustion at Shenque(CV8)and Guanyuan(CV4)may alleviate the central pain sensitization in PD rats by down-regulating TRPV1 channel expression in the spinal dorsal horn and hypothalamus,thus playing an analgesic effect.

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 investigate the prevalence and risk factors of overweight and obesity among Chinese children aged 3-18 years from 11 provinces, antonomous regions, or municipalities.Methods:This national cross-sectional community health survey utilized a multistage stratified cluster-random sampling method to recruit 193 997 nationally representative participants from 11 provinces, autonomous regions, or municipalities between January 2017 and December 2019. All participants underwent physical examinations, and their caregivers completed questionnaires assessing participants′ dietary, lifestyle, familial, and perinatal information. Multilevel multinomial logistic regression models were employed to identify the potential risk factors.Results:The cohort comprised 193 997 children (102 178 boys, 91 819 girls),aged (10±4) years. Overall prevalence rates were 30 574(15.8%)overweight children and 17 217(8.9%) obesity children. Boys exhibited higher overweight and obesity rates than girls (17.0% (17 368/102 178) vs. 14.4% (13 206/102 178), 11.3% (11 553/91 819) vs. 6.2% (5 664/91 819), χ2=249.12,1 578.69,both P<0.001). The detection rates of obesity in Tanner stage 2 and 3 were the highest in boys and girls, with 13.4%(2 231/16 665) and 8.6%(880/10 221) respectively. Risk factors for obesity included parental overweight (paternal OR=2.34 and maternal OR=2.29), annual household income of 100 000-200 000 yuan (compared with<100 000 yuan, OR=1.04), higher paternal education (compared with below high school,high school and a college education OR=1.09,1.14), birth weight >4.0 kg (≤5 and>5 years old OR=1.74, 1.44,respectively), and western food consumption≥1 time/month (compared with<1, 1-2, 3-4,>4 times/month OR=1.36, 1.30, 1.67(≤5 years), 1.19, 1.16, 1.15 (>5 years), respectively) (all P<0.05). Conversely, coarse grain intake≥1 times/week (compared with<1 times/week, every day, 3-4, 1-2 times/week OR=0.74, 0.80, 0.71 (≤5 years), 0.75, 0.87, 0.90(>5 years), respectively, all P<0.05) was associated with reduced obesity risk. Conclusions:Obesity epidemiology in children demonstrates significant heterogeneity across age, gender, geographic regions, and pubertal stages. It is necessary to establish a personalized prevention and control strategy.

Objective To investigate the relationship between serum programmed cell death 4(PDCD4),platelet-derived growth factor-BB(PDGF-BB)levels and atherosclerotic cardiovascular disease(ASCVD)in patients with type 2 diabetes mellitus(T2DM).Methods A total of 238 T2DM patients admitted to 3201 Hospital from January 2022 to August 2024 were selected as the T2DM group,and 120 healthy volunteers who visited the hospital for physical examination during the same period were selected as the control group.T2DM patients were divided into ASCVD group(82 cases)and non-ASCVD group(156 cases)according to the presence or absence of ASCVD.The serum levels of PDCD4 and PDGF-BB were detected by enzyme-linked immunosorbent assay.Multivariate unconditional Logistic regression was used to analyze the relationship be-tween serum PDCD4 and PDGF-BB levels and ASCVD in T2DM patients.Receiver operating characteristic curve was used to analyze the predictive efficiency of serum PDCD4 and PDGF-BB levels for ASCVD in T2DM patients.Results Compared with the control group,the serum levels of PDCD4 and PDGF-BB were signifi-cantly increased in the T2DM group(P<0.05).The incidence of ASCVD in the 238 patients with T2DM was 34.45%(82/238).Compared with the non-ASCVD group,the ASCVD group had significantly higher serum levels of PDCD4 and PDGF-BB(P<0.05).Hypertension,hyperlipidemia,high glycosylated hemoglobin,high PDCD4 and high PDGF-BB were independent risk factors for ASCVD in T2DM patients(P<0.05).The area under the curve of serum PDCD4 and PDGF-BB levels combined to predict ASCVD in T2DM patients was 0.873,which was larger than 0.790 and 0.780 predicted by serum PDCD4 and PDGF-BB levels alone(P<0.05).Conclusion The serum levels of PDCD4 and PDGF-BB are increased in patients with T2DM,which are independent risk factors for ASCVD.The combination of PDCD4 and PDGF-BB has a high predictive efficiency for ASCVD in patients with T2DM.

Abstract Modern western medicine typically focuses on treating specific symptoms or diseases, and traditional Chinese medicine (TCM) emphasizes the interconnections of the body’s various systems under external environment and takes a holistic approach to preventing and treating diseases. Phenomics was initially introduced to the field of TCM in 2008 as a new discipline that studies the laws of integrated and dynamic changes of human clinical phenomes under the scope of the theories and practices of TCM based on phenomics. While TCM Phenomics 1.0 has initially established a clinical phenomic system centered on Zhenghou (a TCM definition of clinical phenome), bottlenecks remain in data standardization, mechanistic interpretation, and precision intervention. Here, we systematically elaborates on the theoretical foundations, technical pathways, and future challenges of integrating digital medicine with TCM phenomics under the framework of “TCM phenomics 2.0”, which is supported by digital medicine technologies such as artificial intelligence, wearable devices, medical digital twins, and multi-omics integration. This framework aims to construct a closed-loop system of “Zhenghou–Phenome–Mechanism–Intervention” and to enable the digitization, standardization, and precision of disease diagnosis and treatment. The integration of digital medicine and TCM phenomics not only promotes the modernization and scientific transformation of TCM theory and practice but also offers new paradigms for precision medicine. In practice, digital tools facilitate multi-source clinical data acquisition and standardization, while AI and big data algorithms help reveal the correlations between clinical Zhenghou phenomes and molecular mechanisms, thereby improving scientific rigor in diagnosis, efficacy evaluation, and personalized intervention. Nevertheless, challenges persist, including data quality and standardization issues, shortage of interdisciplinary talents, and insufficiency of ethical and legal regulations. Future development requires establishing national data-sharing platforms, strengthening international collaboration, fostering interdisciplinary professionals, and improving ethical and legal frameworks. Ultimately, this approach seeks to build a new disease identification and classification system centered on phenomes and to achieve the inheritance, innovation, and modernization of TCM diagnostic and therapeutic patterns.

OBJECTIVE: To assess health equity in the Yangtze River region to improve understanding of the correlation between hand, foot, and mouth disease (HFMD) and socioeconomic factors. METHODS: From 2014-2016, data on HFMD incidence, population statistics, economic indicators, and meteorology from 26 cities along the Yangtze River were analyzed. A multi-city random-effects meta-analysis was performed to study the relationship between temperature and HFMD transmission, and health equity was assessed with respect to socio-economic impact. RESULTS: Over the study period, 919,458 HFMD cases were reported, with Shanghai (162,303) having the highest incidence and Tongling (5,513) having the lowest. Males were more commonly affected (male-to-female ratio, 1.49:1). The exposure-response relationship had an M-shaped curve, with two HFMD peaks occurring at 4 °C and 26 °C. The relative risk had two peaks at 1.30 °C (1.834, 95% CI: 1.204-2.794) and 31.4 °C (1.143, 95% CI: 0.901-1.451), forming an M shape, with the first peak higher than the second. The most significant impact of temperature on HFMD was observed between -2 °C and 18.1 °C. The concentration index (0.2463) indicated moderate concentration differences, whereas the Theil index (0.0418) showed low inequality in distribution. CONCLUSION The incidence of HFMD varied across cities, particularly with changes in temperature. Economically prosperous areas showed higher risks, indicating disparities. Targeted interventions in these areas are crucial for mitigating the risk of HFMD.

OBJECTIVE: This study aimed to explore the association between body mass index (BMI) and mortality based on the 10-year population-based multicenter prospective study. METHODS: A general population-based multicenter prospective study was conducted at four sites in rural China between 2013 and 2023. Multivariate Cox proportional hazards models and restricted cubic spline analyses were used to assess the association between BMI and mortality. Stratified analyses were performed based on the individual characteristics of the participants. RESULTS: Overall, 19,107 participants with a sum of 163,095 person-years were included and 1,910 participants died. The underweight (< 18.5 kg/m ²) presented an increase in all-cause mortality (adjusted hazards ratio [ aHR] = 2.00, 95% confidence interval [ CI]: 1.66-2.41), while overweight (≥ 24.0 to < 28.0 kg/m ²) and obesity (≥ 28.0 kg/m ²) presented a decrease with an aHR of 0.61 (95% CI: 0.52-0.73) and 0.51 (95% CI: 0.37-0.70), respectively. Overweight ( aHR = 0.76, 95% CI: 0.67-0.86) and mild obesity ( aHR = 0.72, 95% CI: 0.59-0.87) had a positive impact on mortality in people older than 60 years. All-cause mortality decreased rapidly until reaching a BMI of 25.7 kg/m ² ( aHR = 0.95, 95% CI: 0.92-0.98) and increased slightly above that value, indicating a U-shaped association. The beneficial impact of being overweight on mortality was robust in most subgroups and sensitivity analyses. CONCLUSION This study provides additional evidence that overweight and mild obesity may be inversely related to the risk of death in individuals older than 60 years. Therefore, it is essential to consider age differences when formulating health and weight management strategies.

Objective To construct a differential diagnosis model for systemic lupus erythematosus(SLE)from other autoimmune diseases based on the conventional test indicators in clinical laboratory,so as to improve the diagnostic efficacy of the existing test indicators.Methods The data of 178 SLE patients(SLE group)and 196 patients with other autoimmune diseases(control group)diagnosed in Sichuan Provincial People's Hospital from Apr.2022 to Mar.2023 were retrospectively analyzed.The differences in the levels of 19 clinical routine indicators between the 2 groups were analyzed.The least absolute shrinkage and selection operator(LASSO)regression was used to screen for test indicators with non-zero coefficients.These indicators were then used in logistic regression to construct a Nomogram model for SLE differential diagnosis.Model performance was assessed using receiver operating characteristic(ROC)curves and decision curve analysis.Results The levels of anti-cardiolipin antibody immunoglobulin(Ig)G,anti-cardiolipin antibody IgA,high-sensitivity C reactive protein(hs-CRP),D-dimer,and thrombin time(TT)in the SLE group were significantly higher than those in the control group(all P＜0.05),while the levels of IgM,complement 3(C3),complement 4(C4),prothrombin time(PT),and activated partial thromboplastin time(APTT)in the SLE group were significantly lower than those in the control group(all P＜0.05).Through LASSO regression,IgM,C3 and C4 were selected as the most likely indicators with non-zero coefficients.Multivariate logistic regression analysis showed that the differential diagnosis model was Logit P=4.18-1.34 × IgM-1.70 × C3-6.61 × C4.The area under the curve of this model was 0.80(95％confidence interval 0.76-0.85),with a sensitivity of 0.77 and a specificity of 0.74.Decision curve analysis demonstrated favourable clinical utility within a threshold probability range of 0.2-0.9.Conclusion The present model,constructed using the clinical routine indicators,such as IgM,C3 and C4,is helpful for the differential diagnosis of SLE from other autoimmune diseases and has good clinical application value.

Lentiviral vectors(LVs)are key gene delivery tools for integrating target genes into the host genome,but they may also pose risks of insertional mutagenesis.The vector copy number(VCN)in cells is critical for determining the safety of gene modification.However,the reliability and accuracy of its quantification process are influenced by multiple factors.Developing cell reference materials with specific vector copy numbers represents a viable approach to enhance the reliability and consistency of measurement results,enabling quality control of the quantification process and traceability of outcomes.However,the preparation of such reference materials faces challenges in cell sample design,preparation protocols,and advanced quantification techniques.In this study,T lymphocyte cell line Jurkat-based reference materials with LV gene copy numbers of 1 and 2 copy/cell were developed.A high-precision duplex digital polymerase chain reaction(dPCR)method was established to quantify the LV gene and endogenous genes simultaneously.Additionally,the results of dPCR were cross-validated through next-generation sequencing and flow cytometric analysis.Ultimately,confocal microscopy characterization results showed that the developed cell reference materials had intact morphology.The quantification result of VCN-1 was(1.07±0.11)copy/cell,and that of VCN-2 was(2.09±0.21)copy/cell.These cell reference materials demonstrated compliance with stability and homogeneity requirements,and could be applied for quality control throughout the VCN measurement workflow and metrological traceability,improving the accuracy,comparability,and validity of copy number measurements.
