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 evaluate the validity and reliability of the Simplified Chinese version of the Beck Cognitive Insight Scale(SC-BCIS).Methods:Totally 188 patients with schizophrenia meeting the Diagnostic and Statistical Manual of Mental Disorders,Fifth Edition(DSM-5)diagnostic criteria were selected for SC-BCIS and the Insight and Treatment Attitudes Questionnaire(ITAQ)assessment.Thirty-eight patients were selected for retest-ing within 4 weeks.The item analysis was conducted using the Spearman correlation method,and the reliability of the scale was tested with Cronbach's α coefficient and ICC coefficient.The structural validity of the scale was ex-amined through principal component analysis and exploratory factor analysis.Results:The correlation coefficients between the 15 item scores and the total score of the SC-BCIS all met the screening criteria.The Cronbach's α coef-ficient of the scale was 0.69,the test-retest ICC value was 0.82,the ICC coefficient between the SC-BCIS and ITAQ scales was 0.83,and the scale had a two-factor structure,with a cumulative contribution rate of 42.4％for the two factors.Conclusion:The Simplified Chinese version of the Beck Cognitive Insight Scale(SC-BCIS)has good validity and reliability in measuring cognitive insight in patients with schizophrenia.

Objective:Exploring the association between Life's Crucial 9 (LC9) and the risk of thyroid dysfunction (TD), as well as its potential predictive capacity.Methods:A total of 247 600 TD-free participants from the UK Biobank were enrolled in the study. The LC9 score was divided into three CVH groups: low (0-), medium (50-), and high (80-100). Cox proportional hazards regression models were used to calculate the HRs and 95% CIs of the risk of TD with LC9 CVH status. Calculate Harrell's concordance index ( C-index), net reclassification improvement (NRI), and integrated discrimination improvement (IDI) to evaluate the predictive ability of the LC9 score and Life's Essential 8 (LE8) score. Results:During a median follow-up of 12.3 years, 5 515, 911, and 4 869 new cases of TD, hyperthyroidism, and hypothyroidism were documented, respectively. Participants with a high LE8 CVH group had 57.00% ( HR=0.43, 95% CI: 0.38-0.49), 55.00% ( HR=0.45, 95% CI: 0.34-0.60), and 58.00% ( HR=0.42, 95% CI: 0.37-0.47) lower risk of TD, hyperthyroidism, and hypothyroidism, respectively, than those with low CVH group. Compared with the LE8 score, the improvement in C-index for the LC9 score predicted TD risk was 0.004 (95% CI: 0.001-0.007), the NRI was 0.101 (95% CI: 0.021-0.103), and the IDI was 0.001 (95% CI: 0.000-0.001). Conclusions:The better CVH status, defined by LC9, was associated with a lower risk of TD. Compared to the LE8 score, the LC9 score demonstrated a significant enhancement in both risk discrimination and reclassification capability for TD risk.

Background: In the field of neuroscience research, executive functions (EFs) are of great significance. Patients with Parkinson’s disease (PD) often encounter the problem of EFs impairment, which severely affects their lives and health.However, currently, the methods for evaluating EFs in experimental mice are limited, and there is a lack of effective evaluation indicators for touchscreen behavioral tests in different disease model mice. This study aims to establish a paradigm process and an evaluation baseline for touchscreen behavioral analysis in PD model mice, deeply explore the mechanisms of EFs impairment in PD, and provide a crucial foundation for subsequent research and treatment. Methods: Thirty clean - grade SNCA*A53T transgenic mice and forty clean - grade C57BL/6J wild - type mice were selected. For A53T mice, genetic identification was carried out. Molecular biology techniques such as PCR were used to determine their genetic characteristics. Protein detection was conducted through methods like Western blot to clarify the expression of relevant proteins. In terms of behavioral tests, the five - choice serial reaction time task (5 - CSRT) was adopted, and various behavioral data of mice in this task were recorded. Four groups were set up: the control group, the MPTP group. Different groups of mice were given specific treatments. For example, the MPTP group of mice was injected with MPTP to construct a drug - induced PD model. Principal component analysis (PCA) and receiver operating characteristic (ROC) curves were used to analyze the obtained touchscreen behavioral baseline indicators of mice, and key indicators were screened and evaluated. Results: In the 5 - CSRT, the optimal stage for wild - type C57 mice to achieve an accuracy rate of ≥ 80% was from the 11th to the 13th cycle, while for A53T mice, it was the 11th cycle. The EFs of A53T mice were impaired, with abnormalities in the accuracy rate, trace number, and number of punished times in the 5 - CSRT. When identifying drug - induced PD models, the 13th cycle of the 5 - CSRT was more effective; when identifying transgenic PD models, the 11th cycle was more suitable. Interventions could be carried out after the baseline accuracy rate reached 80%. Through the “genetic - environmental” dual - axis drive, the “chronic - acute” time - dimension complementarity, and the “mechanism - transformation” multi - level verification, the A53T and MPTP dual models were used to comprehensively cover the pathological cycle of PD EFs impairment. Conclusions This study has successfully established a paradigm process and an evaluation baseline for touchscreen behavioral analysis in PD model mice. This provides an important basis for a deep understanding of the mechanisms of EFs impairment in PD patients, has potential guiding significance for the development of intervention strategies and treatment methods for EFs impairment in PD patients, and is expected to promote new progress in PD research in the field of neuroscience.
