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 article introduces the specific methods and basis for the formation of recommendations in this part of the guide.

Objective To analyze the infection status and epidemic trends of soil-borne nematode infections in Yubei, Chongqing City, in 2010,2021, and 2022. Methods The local populations from four survey sites of four towns in 2010 and five sites of five towns in 2021 and 2022 were surveyed regarding their basic information using a unified form. Fecal samples of the participants were collected and tested for soil-borne nematode infections using the modified Kato-Katz thick smear method. Results In 2010, 2 049 participants were surveyed, followed by 1 000 participants in 2021 and 2022. The overall prevalence of parasitic infections declined significantly from 3.86% to 0.20%. In 2010, soil-transmitted nematode included hookworms(3.81%) and roundworms(0.29%). In 2021, the infection rates of roundworms and hookworms were 1.70% and 0.10% respectively. Notably, only Ascaris was identified in 2022(0.20%). The≥60 age group consistently exhibited the highest infection rates across all surveys, followed by the 40-59 age group. The infection rates of males in the three surveys were 3.31%,1.92%, and 0.20% respectively, and those of females were 4.37%, 1.46%, and 0.20% respectively. There was no statistically significant difference in the infection rates between males and females. Educational attainment was inversely associated with infection; in 2010, the highest prevalence was observed among those with primary education or below, whereas in 2021, illiterate or semi-literate individuals showed the highest susceptibility. The occupational distribution of infections in 2010 indicated that retirees (8.33%), farmers(4.86%), and homemakers or unemployed individuals(3.45%)were the most affected. However, in 2021 and 2022, farmers emerged as the predominant occupational group with soil-transmitted nematode infections. Conclusions The infection rate of soil-borne nematodes showed a decreasing trend in Yubei, and the infection species changed from hookworms in 2010 to Ascaris in 2022. Farmers, the elderly, and people with low education levels should continue to be the focus of preventive and control efforts.

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 investigate the value of dual-energy CT parameters in the evaluation of pathological grade of pancreatic ductal adenocarcinoma.Methods:80 cases of pancreatic ductal adenocarcinoma confirmed by pathology were retrospectively analyzed and divided into high grade group (36 cases) and low grade group (44 cases) according to their differentiation degree. All 80 patients underwent SOMATOM Force DECT for arterial phase (AP) and pancreatic phase (PP) scanning, and measured dual-energy parameters including dual-phase iodine concentration (IC AP, IC PP) in tumors and normal pancreatic parenchyma, pancreatic phase and arterial phase iodine concentration difference (ICD PP-AP) in tumors, dual-phase iodine uptake ratio (IUR AP, IUR PP) , dual-phase tumor/normal pancreatic parenchyma fat fraction ratio, and dual-phase slope of energy spectrum curve. Differences between two groups were compared by two independent sample t-test or Mann-Whitney U test or chi-square test. The multivariate logistic regression model was used to analyze the influencing factors of pathological grading of PDAC. Results:There were statistically significant differences in gender, age, aspect ratio, positive lymph node, fat fraction ratio in pancreatic phase between the two groups ( P< 0.05) . The multivariate logistic regression analysis showed that fat fraction ratio in pancreatic phase ( OR=1.781, 95% CI 1.127-2.814, P=0.013) , positive lymph node ( OR=4.870, 95% CI 1.488-15.938, P=0.009) , aspect ratio ( OR=0.019, 95% CI 0.001-0.437, P=0.013) were independent factors influencing the pathologic grade of PDAC. Conclusion:Parameters of dual-energy CT are valuable in the evaluation of pathological grading of PDAC.

Objective:To investigate disease characteristics of patients with psoriatic arthritis (PsA) based on the PsA cohort in West China Hospital, so as to provide a reference for clinicians in its diagnosis, treatment, and evaluation strategy formulation.Methods:A cross-sectional study was carried out, and a descriptive analysis was conducted on clinical data from PsA patients who were treated at the Department of Dermatology, West China Hospital, Sichuan University between April 2, 2020, and January 21, 2025. Demographic characteristics, clinical manifestations, laboratory and imaging findings, and treatment modalities were analyzed.Results:A total of 530 PsA patients were included, of whom 332 (62.6%) were males and 198 (37.4%) were females, with ages of 44.1 ± 12.4 years. Skin lesions preceded joint symptoms in 452 patients (85.3%), with time intervals ( M [ Q1, Q3]) of 8.0 (3.0, 15.0) years. Overweight or obesity was observed in 319 patients (60.2%), and 188 (35.5%) had comorbid fatty liver. Peripheral joint involvement was common (485 cases, 91.5%), with the proximal interphalangeal joints being most frequently affected by tenderness (172 cases, 35.5%) and swelling (119 cases, 24.5%) ; the number of enthesitis cases identified by ultrasonography (116 cases, 23.9%) was significantly higher than that by clinical examination (82 cases, 15.5%) ; axial joint involvement was observed in 258 patients (48.7%), with the sacroiliac joints most commonly affected (201 cases, 77.9%). Regarding treatment, conventional systemic drugs were predominant in the treatment of psoriasis prior to the diagnosis of PsA; after the diagnosis of PsA, the number of patients receiving targeted therapies increased to 334 (63.0%), with interleukin-17 inhibitors being the most common (140 cases, 26.4%), followed by tumor necrosis factor-α inhibitors (106 cases, 20.0%) and Janus kinase inhibitors (39 cases, 7.4%) . Conclusions:PsA predominantly affects males over 40 years old and is characterized by preceding skin lesions, delayed diagnosis, and multiple comorbidities. High-frequency ultrasound has advantages in the early detection of peripheral enthesitis. Further attention is needed for managing comorbidities such as fatty liver and obesity-related metabolic conditions.

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:This study aimed to evaluate the long-term efficacy and safety of rituximab(RTX)combined with calcineurin inhibitors(CNI)in the treatment of refractory nephrotic syndrome(RNS).Methods:A total of 80 patients with steroid-dependent/resistant RNS were prospectively enrolled and randomly assigned to an observation group(RTX+CNI,n=40)and a control group(CNI monotherapy,n=40).Patients were followed up for 24 months.Dynamic comparisons were made between the two groups regarding complete remission rate,relapse rate,24-hour urinary protein,kidney injury molecule-1(KIM-1),and adverse reactions.Results:The complete remission rate(CR)in the observation group was significantly higher than that in the control group at all time points(24-month CR:100％vs 90％,P＜0.05).The 24-month relapse rate was significantly lower in the observation group compared to the control group(0％vs 10％,P＜0.05).Combination therapy significantly reduced 24-hour urinary protein levels(6 months:2.13±0.63 vs 3.86±1.01 g/24 h,P＜0.001)and the renal injury marker KIM-1(6 months:1.53±0.41 vs 2.23±0.65 ng/mL,P＜0.001),and increased the CD4+/CD8+ ratio(24 months:2.03±0.52 vs 1.72±0.41,P＜0.05).There was no significant difference in the incidence of adverse reactions between the two groups(15％vs 20％,P=0.556).Conclusion:RTX combined with CNI significantly improves the long-term remission rate and reduces the risk of relapse in RNS.Its dual immunomodulatory and multi-target renal protective effects provide evidence-based support for optimizing the treatment of refractory nephrotic syndrome.

Objective:To systematically and comprehensively retrieve studies on urethra care for patients with urinary catheter at home and abroad, so as to provide a reference for removing low-value care measures in the future.Methods:Arksey and O'?Malley scoping review method was used to systematically search the China National Knowledge Infrastructure, China Biology Medicine disc, WanFang Data, VIP, PubMed, Cochrane Library, CINAHL, Embase, and Web of Science. The search period was from database establishment to January 1, 2024. Literature was screened based on inclusion and exclusion criteria, and catheter care site, disinfection/cleaner type, frequency, institutional norms, and determinants were independently extracted by two researchers, where determinants were framed based on the theoretical domains framework.Results:A total of 21 papers were included. Urethra low-value care measures were reflected in the selection of nursing solutions that differed significantly from guideline recommendations and were inconsistently standardized across hospitals. Thirteen strategies were proposed to remove urethra low-value care measures. Factors that influenced the removal of low-value care behaviors included knowledge, reinforcement, environment and resources, social influences, personal roles and identities, outcome beliefs and memories, and attention and decision-making processes.Conclusions:Future researchers should further refine the evidence on urethra care and develop contextualized care for complex, multilevel healthcare settings to achieve continuous improvement and high quality care at low cost.
