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.

Objective:To establish a cutoff level of anti-Müllerian hormone(AMH)which could help with the di-agnosis of polycystic ovary syndrome(PCOS)in adults,and to analyze the risk factors of metabolic syndrome(MS).Methods:A retrospectively analyzed 426 PCOS patients(PCOS group)and 205 healthy controls aged 20-39 years from the Health Checkup Center of the Gynecological Endocrine Center,Hunan Maternal and Child Health Hospital from January 2021 to December 2023.AMH diagnostic validity was estimated by receiver operating characteristic(ROC)curves.Patients were subgrouped into PCOS combined metabolic syndrome group(MS-PCOS)and the uncomplicated MS group(UMS-PCOS)according to metabolic status.Multivariate Logistic regression analysis was performed to determine the risk factors for MS in PCOS patients.Results:The serum AMH level was higher in PCOS group than that in the control group(8.42±3.71 ng/ml vs.2.99±0.94 ng/ml,P＜0.001).AMH cutoff for the diagnosis of PCOS was determined as≥4.87 ng/ml on ROC analysis,and the area under the curve is 0.981 with 92.7％sensitivity and 94.6％specificity.The prevalence of MS was 18.3％(78 ca-ses)in PCOS group.Subgroup analysis showed that MS-PCOS patients had higher waist circumference,BMI,fasting glucose,dyslipidemia,hypertension(BP＞130/85 mmHg),and hormone related index androgen level,but lower AMH vs.UMS-PCOS.Multivariate Logistic regression analysis identified insulin resistance(OR 39.17,95％CI 9.33-164.48),BMI ≥24 kg/m2(OR 3.72,95％CI 1.86-7.45),and hyperandrogenism(OR 2.56,95％CI 1.34-4.89)as independent risk factors of MS.AMH was negatively associated with MS,a single-unit increase in AMH was associated with an 17％decrease in odds of MS(OR 0.83,95％CI 0.73-0.95,P=0.006).Conclusions:Serum AMH levels were significantly higher in adult PCOS patients,with an optimal diagnostic threshold of 4.87 ng/ml.Hyperandrogenism and low AMH levels may predict a higher risk of MS,in addition to metabolism-related factors.

Objective To verify the feasibility and safety of three-dimensional(3D)image acquisition by C-arm combined with orthopedic robot-assisted iliosacral screw fixation through S3 vertebra.Methods From July 2023 to June 2024,a total of 4 patients with closed pelvic fracture were surgically treated.Preoperative pelvic CT 3D reconstruction showed the presence of an ideal iliosacral screw bone channel through S3 vertebra which required screw fixation.There was no such channel through the S1 vertebra,or the stability of fixation through the S3 channel was better than that through the S1 channel.The 3D image acquisition by C-arm combined with orthopedic surgical robot was used to insert screws.Follow-ups were conducted for at least 6 months after surgery to assess fracture healing and limb function.Results All the 4 patients were successfully implanted with a S2 and a S3 iliosacral screw,and all the 8 screws did not penetrate the cortical bone.Three cases had excellent Majeed scores and 1 case had good scores at 3 months after surgery.Follow-ups were conducted for 18,12,7,and 6 months after surgery,respectively,and all fractures healed smoothly without any loosening or breakage of screws.Conclusion 3D image acquisition by C-arm combined with orthopedic robot-assisted iliosacral screw fixation through S3 vertebra is feasible,safe and effective.

Objective:To explore a factor analysis method for job training needs based on "P4 medicine", and to provide evidence-based support for optimizing continuing education systems for medical staff in military rest homes and sanatoriums.Methods:A cross-sectional study was conducted with 95 medical staff from military rest homes and sanatoriums within the support system who participated in job training at Xinqiao Hospital. A structured questionnaire was developed based on the "P4 medicine" framework. After two rounds of Delphi expert consultation, 46 core indicators were selected. A principal component analysis was used to extract common factors, and a model of hierarchical needs was constructed by combining varimax rotation and entropy weight methods.Results:Four common factors were extracted, accounting for 81.564% cumulative variance. The first factor "dynamic updating of geriatric medical knowledge" (31.83%) covered clinical core competencies in managing geriatric comorbidities and recognizing critical values. The second factor "emergency responsiveness and personalized care" (26.05%) focused on military medical regulations, emergency treatment protocols, and tailored interventions. The third factor "multidisciplinary collaboration and leadership development" (12.41%) emphasized team reorganization in combat-ready scenarios. The fourth factor "integration of intelligent technologies" (11.29%) reflected data-driven decision-making needs. Entropy weight analysis highlighted dynamic medical knowledge updates (e.g., emergency skills with a weight of 0.050) and AI applications with a weight of 0.019 among the top 10% high-weight indicators.Conclusions:The "P4 medicine" effectively delineates the multidimensional training needs of grassroots medical personnel. Its four-dimensional structure (predictive, normative, collaborative, and innovative) provides a theoretical framework for curriculum design. We recommend constructing tiered training modules prioritizing technology-enabled mechanisms to enhance the precision and sustainability of geriatric healthcare services.

Compounds isolated from Epimedium include the total flavonoids of Epimedium , icariin, and its metabolites (icaritin, icariside I, and icariside II), which have similar molecular structures. Modern pharmacological research and clinical practice have proved that Epimedium and its active components have a wide range of pharmacological effects, especially in improving sexual function, hormone regulation, anti-osteoporosis, immune function regulation, anti-oxidation, and anti-tumor activity. To date, we still need a comprehensive source of knowledge about the pharmacological effects of Epimedium and its bioactive compounds on the male reproductive system. However, their actions in other tissues have been reviewed in recent years. This review critically focuses on the Epimedium , its bioactive compounds, and the biochemical and molecular mechanisms that modulate vital pathways associated with the male reproductive system. Such intrinsic knowledge will significantly further studies on the Epimedium and its bioactive compounds that protect the male reproductive system and provide some guidances for clinical treatment of related male reproductive disorders.
