Objective: To characterize perioperative dynamic changes in immune-cell phenotypes and inflammatory cytokines in patients undergoing CPB (cardiopulmonary bypass) cardiac surgery, and to explore their associations with postoperative outcomes. Methods: In this prospective cohort study, 120 adult patients who underwent elective cardiac surgery under CPB at West China Hospital from May 2022 to March 2023 were enrolled. Perioperative immune-cell phenotypes and concentrations of 40 inflammation-related cytokines were measured. The primary outcomes were the sequential organ failure assessment (SOFA) score at 24 h after surgery and ΔSOFA (the peak SOFA score within 48 h after surgery minus the preoperative SOFA score). Secondary outcomes included major adverse cardiovascular events (MACE), acute kidney injury (AKI), respiratory failure, severe liver injury, and infection. Results: The mean age of enrolled patients was 57±10 years. Of these, 52% (62/120) were male and 90% (108/120) underwent valve surgery. During the rewarming to the end of CPB, neutrophil counts rapidly increased (7.39×10 /L vs preoperative 3.07×10 /L, P<0.001), with significant upregulation of CD11b (7.30×10 /L vs preoperative 3.05×10 /L, P<0.001) and CD54 (7.15×10 /L vs preoperative 2.99×10 /L, P<0.001). Lymphocyte counts increased at the end of CPB (1.75×10 /L vs preoperative 1.12×10 /L, P<0.001) but decreased significantly at 24 h after surgery (0.59×10 /L vs preoperative 1.12×10 /L, P<0.001). Plasma analysis showed that multiple pro-inflammatory cytokines increased during CPB and remained elevated up to 24 h after surgery; five chemokines and the anti-inflammatory cytokine IL-10 peaked at the end of CPB. The SOFA score increased from 1 (1, 2) preoperatively to 7 (5, 10) at 24 h after surgery, with a ΔSOFA of 6 (4, 8). Within 30 days after surgery, 48 patients (40.0%) developed AKI, 17 (14.2%) developed infection, 4 (3.3%) developed severe liver injury, 3 (2.5%) developed respiratory failure, and 3 (2.5%) experienced MACE. During the 2-year follow-up, 8 patients (6.7%) experienced MACE and 5 (4.2%) died. Conclusion: Multi-organ dysfunction is common after cardiac surgery under CPB (median ΔSOFA, 6), accompanied by perioperative activation of multiple immune-cell subsets and upregulation of pro-inflammatory, anti-inflammatory, and chemotactic mediators. This study provides data-driven evidence and research clues for further investigation of the associations between CPB-related immune perturbations and postoperative organ dysfunction and clinical outcomes.

This guideline addresses 53 recommendations related to plasma and platelet transfusion in critically ill children with 8 kinds of diseases, laboratory testing, selection/treatment of plasma and platelet components, and research priorities. This paper introduces the specific methods and results of the recommendation formation of the guideline.

Objective:To explore the relationship between life events, anxiety, depression, and behavior problems in adolescents.Methods:From September to October 2022, the cluster sampling method was used to select 5 341 adolescents from 4 middle schools in Xinxiang urban area.The subjects and their parents were investigated by the adolescent self-rating life events check list (ASLEC), generalized anxiety disorder scale (GAD-7), patient health questionnaire (PHQ-9), and child behavior checklist (CBCL). SPSS 27.0 software was used for Spearman correlation analysis, and AMOS 28.0 software was used to construct the structural equation model.Results:The scores of anxiety, depression, and behavioral problems were 1 (0, 4), 1 (0, 4), and 3 (0, 10). The total score of life events was 5 (1, 13), and the dimensions scored as follows: interpersonal conflict 1 (0, 4), academic pressure 2 (0, 5), punishment 0 (0, 2), loss 0 (0, 0), health and adaptation problem 0 (0, 1), and others 0 (0, 2). There were positive correlations between life events and its dimensions, depression, anxiety and behavioral problems ( r=0.28-0.69, all P<0.01). In the overall population, anxiety and depression played parallel mediating roles in the impact of life events on behavior problems. Life events could positively predict anxiety ( β=0.68, P<0.01), and anxiety could positively predict behavior problems ( β=0.04, P=0.02). Life events could positively predict depression ( β=0.77, P<0.01), and depression could positively predict behavior problems ( β=0.18, P<0.01). The standardized total effect size of the impact of life events on behavioral problems was 0.622 (95% CI=0.564-0.675). The standardized direct effect size and indirect effect size were 0.460 (95% CI=0.374-0.539) and 0.162 (95% CI=0.108-0.218), accounting for 74.0% and 26.0%of the total effect, respectively. After stratification by gender, the results for male adolescents were consistent with the overall population, while the mediating effect of anxiety was not significant in the female adolescents. Conclusion:Life events can lead to anxiety and depression in adolescents, thereby increasing the risk of behavior problems.

Background::The increasing incidence of inflammatory bowel disease (IBD) presents significant medical and societal challenges. A well-designed IBD database is crucial for both epidemiological studies and clinical management. However, inconsistencies between regional databases hinder cross-institutional and international research, especially between Eastern and Western societies.Methods::We developed a new IBD database, the 301 IBD database, integrating the IBD clinical characteristics from the Penn IBD database (USA) and the latest IBD guidelines and consensus and clinical practices of the Chinese PLA General Hospital (PLAGH). We applied this database to analyze clinical data of IBD inpatients at PLAGH from 2008 to 2023.Results::The 301 IBD database contains 490 items in 6 sections including demographic characteristics, personal history, clinical phenotype, disease activity, laboratory tests and examinations, and treatment. Features of the 301 IBD database include inpatient focus, biochemical indicators and opportunistic infection focus, and more about ulcerative colitis (UC)-associated complications. Single-center analysis revealed an increasing hospitalization trend, from 2.35% in 2008 to 3.94% in 2023. We found that the clinical characteristics of our UC inpatients are predominantly male (62.5%), extensive lesions (55.1%), low usage of biologics (4.1%), and a high incidence of UC-CRC (3.0%). The clinical characteristics of CD inpatients included male predominance (68.39%), early onset age (35.43 ± 14.75-year-old), and high rate of surgery (25.81%).Conclusion::The 301 IBD database, integrating Eastern and Western clinical data, provides a valuable tool for IBD clinical research. Future international, multicenter collaborations are expected to further enhance its utility.

Objective:To explore the changes of atlantoaxial joint spaces and pharyngeal airway after combined orthodontic-orthognathic treatment in skeletal class Ⅲ patients with mandibular deviation.Methods:A total of 34 adult skeletal class Ⅲ patients (10 males and 24 females) with mandibular deviation who received combined orthodontic-orthognathic treatment at the Department of Orthodontics and the Department of Orthognathic Surgery in the Stomatological Hospital of Chongqing Medical University from August 2014 to October 2021 were retrospectively selected. The patients were 22 (5) years old (18-33 years). Cone-beam CT data of patients taken before treatment (T0), after preoperative orthodontics (T1), and 6 to 12 months after orthognathic surgery (T2) were collected. The anterior atlanto-dental interval (ADI), variance of bilateral lateral atlanto-dental interval (VBLADI), the anterior posterior length (APL), maximum transverse width (LTW), aspect ratio (L/W), cross-sectional area (CSA) of each airway cross-section, the airway volumes, as well as the positions of the maxillofacial landmark points [subspinale (point A), supramental (point B), posterior nasal spine (point PNS), the most anterior and superior point of the hyoid bone (point H)] were measured at different time points. The correlations between airway changes, maxillofacial movements as well as the changes in the atlantoaxial joint spaces were also analyzed.Results:During the combined orthodontic-orthognathic treatment, no statistically significant differences were found in the ADI and VBLADI among different treatment time points (all P>0.05). After preoperative orthodontics, the volume of total airway increased from 20 868 (6 669) mm 3 to 21 302 (8 911) mm 3 ( P<0.05). After orthognathic surgery, there were no statistically significant differences in the APL, CSA of the PNS plane, the L/W of the uvula plane, and the nasopharyngeal airway volume compared with those after preoperative orthodontics (all P>0.05). The L/W of the PNS plane after surgery was significantly increased compared with that after preoperative orthodontics ( P<0.05), while other airway parameters were all significantly decreased compared with those after preoperative orthodontics (all P<0.05). Compared with before treatment, the nasopharyngeal airway volume after surgery [6 186 (1 707) mm3] increased significantly ( P<0.05) and the palatopharyngeal airway volume [8 145 (2 594) mm3] and the glossopharyngeal airway volume [5 605 (4 395) mm3] decreased significantly (all P<0.05). There was no statistically significant difference in the total airway volume between after surgery and before treatment ( P>0.05). Correlation analysis showed that after preoperative orthodontics, the amount of the sagittal movement of point B was moderately positively correlated with the total airway volume change ( r=0.40, P=0.022). Before and after orthognathic surgery, the amount of the sagittal movement of point PNS was moderately positively correlated with the changes in the palatopharyngeal airway volume and the total airway volume ( r=0.43, P=0.015; r=0.46, P=0.008). In addition, the change in VBLADI before and after orthognathic surgery was weakly positively correlated with the changes in the CSA of the PNS plane and the APL of the uvula plane ( r=0.35, P=0.029; r=0.38, P=0.016). Conclusions:During the combined orthodontic-orthognathic treatment, the anterior atlanto-dental interval in skeletal class Ⅲ patients with mandibular deviation remained stable among different treatment time points. The total airway volume increased after preoperative orthodontics. After orthognathic surgery, the backward movement of the mandible tended to reduce the size of the pharyngeal airway, and the morphology of the glossopharyngeal airway tended to become more flattened. The changes in the pharyngeal airway dimensions were correlated with the maxillomandibular movements and the atlantoaxial joint space changes.

Recent studies have shown that the physiological homeostasis of oral mucosal cells is regulated by the circadian clock.Dis-ruption or dysfunction of the circadian clock is closely associated with the development of oral squamous cell carcinoma(OSCC).Research based on the circadian clock offers a novel perspective on the pathogenesis and therapeutic strategies for OSCC.However,there is current-ly limited research on this topic,and people generally have insufficient understanding and recognition of the circadian clock.Given the complexity and challenges of circadian clock which is the fourth dimension of medical research,we organize relevant experts based on summarizing the current research results of circadian clock in the pathogenesis and precision diagnosis and treatment of OSCC,combining the scientific principles of the circadian clock's role and their long-term research experience,then summarizes and recommends the con-sensus opinions for the research of circadian clock in the pathogenesis mechanism and precision diagnosis and treatment of human OSCC,with the hope of providing guidance for the basic research and clinical application of circadian clock or circadian rhythm in the pathogene-sis mechanism and precision diagnosis and treatment of oral and maxillofacial squamous cell carcinoma.

OBJECTIVE To investigate the positive test of high-risk human papillomavirus(HR-HPV)among the female population undergoing physical examination in Shenyang,analyze the influencing factors and establish and validate the risk prediction model.METHODS The data were collected from the female population who received HPV test in the physical examination center of a three-A hospital in the whole year of 2023.The prevalence rates of HR-HPV infections and subtypes were described,the influencing factors for the infections were identified.Uni-variate analysis and multivariate logistic regression analysis were performed for the influencing factors for positive test of HR-HPV,and the prediction model was established and validated.RESULTS Totally 6 130 out of 7 759 fe-male population who received HPV test were from Shenyang,the total positive rate of HR-HPV was 10.72％a-mong the population from Shenyang,11.11％among the population from other areas,and there was no signifi-cant difference.The population from Shenyang aged between 21 and 84 years old,with the mean age(48.58±11.64)years old.Among the local population who had the infections,80.21％were the single HPV infection,and 19.79％were multiple infections;HPV52 was the predominant subtype of HPV causing the infections,followed by HPV58 and HPV 16.The result of multivariate analysis showed age,smoking history,gynecological surgery history,allergic history,family annual income and sleep condition were the influencing factors for the positive HR-HPV.The prediction model was established based on the result of the multivariate analysis,the internal vali-dation of the model was carried out by modeling data and receiver operating characteristic(ROC)curves,the area under the curve(AUC)of the prediction model was 0.919,and 95％CI was 0.878 to 0.960,indicating that the prediction model had a high efficiency.CONCLUSIONS The positive rate of HR-HPV test is not relatively high among the physical examination female population in Shenyang,and the positive result is affected by a variety of factors.The population can be vaccinated for prevention and control based on the prediction model targeting to the non-variable factors such as age,meanwhile,the measures such as enhancement of health education,adjustment of health polies and interven-tion to health behaviors should be taken for other controllable factors.

Obesity, as a chronic recurrent disease, has become a major public health challenge in China. To implement the requirements of the Healthy China Initiative (2019—2030), under domestic guidelines or consensus statements on overweight and obesity, and in alignment with the latest scientific advances globally, the Quality control protocol for adult overweight and obesity screening in health management (examination) institutions (2025 edition) was developed. This protocol was drafted by the Health Management Center of Shanghai Changzheng Hospital and formulated through multiple rounds of deliberation by experts in China’s health examination quality control field. The protocol establishes unified standards for screening facilities, personnel qualifications, and measurement or testing procedures. It defines specific screening items, outlines a standardized screening pathway, and sets requirements for the final medical review, ensuring the scientific validity, effectiveness, and safety of the screening process. The implementation of this protocol will enhance the consistency of weight management practices for adults across health examination institutions and strengthen the quality control of overweight and obesity screening programs.
