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 effects of pretreatment with rehmannia glutinosa polysaccharide(RGP)and basic fibroblast growth factor(FGF-2)alone or in combination on the differentiation of bone marrow mesenchymal stem cells(BMSCs)into cardiomyoid cells and the related mechanisms.Methods BMSCs pretreated with FGF-2 and RGP alone or in combination were cultured for 1,2,and 4 weeks.The expression levels of NKx2.5 and GATA-4 were detected by Real-time PCR.BMSCs pretreated with FGF-2 or RGP alone and PI3K/Akt signaling pathway inhibitor LY294002 were used to detect the expression levels of myocardial specific proteins and related pathway proteins by Western blotting.Results Compared with the blank control group,pretreatment with FGF-2 or RGP alone increased the expression rate of myocardial specific markers,and the effect of combined pretreatment with FGF-2 and RGP was more obvious(P＜0.05).Compared with pretreatment with FGF-2 or RGP alone,pretreatment with LY294002 combined with FGF-2 or RGP significantly down-regulated the expression of cardiac-specific proteins in BMSCs and inhibited the phosphorylation of Akt(P＜0.05).Conclusion Both FGF-2 and RGP can induce BMSCs to differentiate into cardiomyocyte-like cells by regulating PI3K/Akt signaling pathway,and the combination of FGF-2 and RGP has a better inductive effect.

Objective:To investigate the relationship between blood pressure trajectories and blood pressure variability with the risk of target organ damage in Chinese population from childhood to middle age.Methods:This study is a population-based, long-term follow-up cohort study. Participants who had their blood pressure measured at least 5 times in the Hanzhong Adolescent hypertension cohort from 1987 to 2023 were included in this study. Group-based trajectory modeling was used to identify different systolic and diastolic blood pressure trajectories, and the subjects were divided into low-increasing group, moderate-increasing group and high-increasing group according to blood pressure trajectories. Blood pressure variability was assessed using standard deviation (SD), variability independent of the mean (VIM), and average real variability (ARV). Target organ damage was evaluated during the final follow-up in 2023 (middle age). Logistic regression models were used to analyze the relationship between blood pressure trajectories and blood pressure variability with the risk of target organ damage.Results:A total of 2 447 subjects were included, with a median age of 48 years, of whom 1 373 were male (56.1%). Based on systolic blood pressure, 868 were in the low-increasing group, 1 238 in the moderate-increasing group, and 341 in the high-increasing group. For diastolic blood pressure, the distribution was 894, 1 263 and 290, respectively. Compared with the low-increasing group of systolic blood pressure, the moderate-increasing group (arteriosclerosis: OR=4.14, 95% CI 2.96-5.79; proteinuria: OR=2.06, 95% CI 1.38-3.07; left ventricular hypertrophy: OR=1.68, 95% CI 1.00-2.82) and high-increasing group (arterial stiffness: OR=15.44, 95% CI 10.14-23.50; proteinuria: OR=5.80, 95% CI 3.63-9.29; left ventricular hypertrophy: OR=2.93, 95% CI 1.55-5.53) had a higher risk of target organ damage (all P<0.005). The moderate-increasing group of diastolic blood pressure had a higher incidence of arterial stiffness ( OR=3.72, 95% CI 2.69-5.12) and proteinuria ( OR=1.67, 95% CI 1.15-2.42) than the low-increasing group (all P<0.005), while the high-increasing group had a significantly higher risk of all type of target organ damage compared to the low-increasing group (arterial stiffness: OR=10.84, 95% CI 7.08-16.61; proteinuria: OR=3.72, 95% CI 2.31-5.99; left ventricular hypertrophy: OR=2.38, 95% CI 1.23-4.59; all P<0.005). Additionally, higher systolic blood pressure variability was associated with an increased incidence of arterial stiffness (SD: OR=2.25, 95% CI 1.96-2.57; VIM: OR=1.64, 95% CI 1.45-1.86; ARV: OR=1.70, 95% CI 1.50-1.93) and proteinuria (SD: OR=1.65, 95% CI 1.44-1.89; VIM: OR=1.41, 95% CI 1.22-1.63; ARV: OR=1.45, 95% CI 1.26-1.67; all P<0.005). The results for diastolic blood pressure variability indicators were similar to those for systolic blood pressure. Conclusion:Early-life blood pressure trajectories are predictive of target organ damage risk in middle age. Higher blood pressure variability is related to an increased risk of arterial stiffness and proteinuria, but was less associated with left ventricular hypertrophy. Focusing on the risk of high blood pressure early in life can help prevent the occurrence of target organ damage in middle age.

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.

Retinal vein occlusion(RVO)is the second most common blinding retinal vascular disease, and its secondary macular edema(ME)is an important cause of visual function impairment in patients. Intravitreal injection of anti-vascular endothelial growth factor(VEGF)drugs serves as the first-line treatment, yet it is confronted with such issues as the need for repeated injections and non-response in some patients. Imaging and laboratory biomarkers play a crucial role in the early accurate diagnosis, prediction of disease progression, and evaluation of visual prognosis of RVO-ME. This study systematically reviews the research progress of imaging and laboratory biomarkers related to the prognosis of RVO-ME after anti-VEGF treatment in recent years, covering imaging biomarkers like central retinal thickness and ellipsoid zone integrity, as well as laboratory biomarkers such as serum APLN and aqueous humor IL-6. It summarizes the associations between different biomarkers and the prognosis of anti-VEGF therapy, aiming to provide a basis for the early accurate assessment and optimization of individualized treatment for RVO-ME patients, which holds significant clinical reference value.

Objective To explore aging effect on healthy cerebral white matter using fixel-based analysis(FBA)on diffusion tensor imaging.Methods Eighty-seven healthy participants were divided into younger group and older group according to their ages,and all of whom were examined with diffusion tensor imaging at 3.0T.The fractional anisotropy(FA)of two groups was compared using whole brain voxel-based analysis(VBA).Then,FBA was used to calculate complexity(CX),fiber density(FD),fiber cross-section(FC)and fiber density and fiber cross-section(FDC)in voxels where older group exhibited significantly lower FA values than younger group.Finally,certain tracts of interest were chosen for tract-specific analyses.Results Compared with younger group,older group had significantly lower FA values in the genu of corpus callosum,splenium of corpus callosum,fornix,and posterior limb of internal capsule(P<0.05).Besides the above regions,older group showed significantly lower FD,FC and FDC in the anterior thalamic radiation,anterior limb of internal capsule,cerebral peduncle,superior longitudinal fasciculus,inferior longitudinal fasciculus,cingulum gyrus,forceps-minor and uncinate fasciculus(P<0.05).In voxels where FA values of older group were significantly lower than those of younger group,strong negative correlation was observed between average CX and average FA,while positive correlation was observed between average FD/FDC and average FA.Quantitative tract-specific analyses showed that older group had showed lower FD,FC and FDC in regard of superior longitudinal fasciculus,inferior longitudinal fasciculus,cingulum,anterior thalamic radiation,forceps-minor and uncinate fasciculus(P<0.05).Conclusion FBA reveals the characteristics of specific fibers and can be used to perform comprehensive and effective evaluation of aging effect on healthy cerebral white matter.

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.

Objective To analyze the correlation of serum levels of GAT A-binding protein 3(GATA-3),T cell immunoglobulin domain and mucin domain protein-3(Tim-3)and retinoid-related orphan nuclear receptor gamma t(RORγt)with cardiac function and myocardial injury in-dicators in patients with coronary heart disease(CHD)and angina pectoris.Methods A retrospec-tive analysis was performed on 120 CHD patients with angina pectoris(observation group)in our hospital from December 2020 to December 2023.They were divided into stable angina subgroup(53 cases)and unstable angina subgroup(67 cases)according to the results of electrocardiography and coronary angiography.Another 120 healthy individuals taking physical examination in our hospital during the same period were subjected and served as the control group.ELISA was used to detect the serum levels of GATA-3,Tim-3 and RORγt.Left ventricular ejection fraction(LVEF),left ventricular end-diastolic diameter(LVEDD),left ventricular end-systolic diameter(LVESD),and left ventricular short-axis shortening rate(FS)were measured by echocardio-graphy.Creatine kinase(CK)and creatine kinase isoenzyme(CK-MB)were detected by biochemi-cal analyzer,and troponin Ⅰ(cTnⅠ)and heart fatty acid binding protein(H-FABP)were detected by electrochemiluminescence immunoassay.Pearson analysis was applied to analyze the correlation the correlation of serum levels of GATA-3,Tim-3 and RORγt with cardiac function and myocar-dial injury indicators.ROC curve was plotted to analyze the predictive value of the above three in-dicators for unstable angina.Results The serum levels of Tim-3 and ROR y t were significantly higher,and that of GATA-3 was obviously lower in the observation group than the control group(397.14±78.42 ng/L vs 246.45±56.81 ng/L,P＜0.01;93.18±19.94 ng/L vs 35.72±7.79 ng/L,P＜0.01;38.21±9.45 ng/L vs 71.62±14.98 ng/L,P＜0.01).The LVEDD and LVESD values were notably higher,while the LVEF and LVFS values were remarkably lower in the observation group than the control group(P＜0.01).The observation group has statistically higher cTnⅠ,CK,CK-MB,and H-FABP levels than the control group(P＜0.01).In the CHD patients with angina pectoris,serum GATA-3 level was positively correlated with LVEF and LVFS,and negatively with LVEDD,LVESD,cTnⅠ,CK,CK-MB,and H-FABP;Tim-3 and RORγt were negatively corre-lated with LVEF and LVFS,and positively with LVEDD,LVESD,cTnⅠ,CK,CK-MB,and H-FABP(P＜0.01).The AUC value of GATA-3,Tim-3,and RORγt alone and in combination in predicting unstable angina was 0.859,0.827,0.780,and 0.921,respectively,with that of combina-tion significantly higher than that of above indicators alone(Z=1.993,3.021,4.532,P=0.036,0.007,0.001).Conclusion As the disease progresses in CHD patients with angina pectoris,serum levels of Tim-3 and RORγt are increasing,while that of GATA-3 is decreasing,and all of them are closely associated with heart function and myocardial injury indicators.
