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 investigate the prevalence of soil-transmitted nematode human infections in Hubei Province from 2016 to 2023, so as to provide insights into formulation of soil-transmitted nematodiasis control strategies and evaluation of soil-transmitted nematodiasis control effectiveness. Methods There were 10 surveillance points established in Hubei Province for soil-transmitted nematodiasis each year from 2016 to 2023. The surveillance points were divided into eastern, western, southern, northern and central regions according to geographical locations, and one administrative village was sampled from a township in each region as a surveillance point. Then, at least 200 permanent residents at ages of over 3 years were randomly sampled at each point, with at least 1 000 individuals sampled. Soil-transmitted nematode infection was detected using a modified Kato-Katz thick smear method (two slides for one stool sample), and Enterobius vermicularis infection was additionally detected with a cellophane tape test among children at ages of 3 to 9 years. The prevalence of soil-transmitted nematode human infections was descriptively analyzed. Results A total of 80 547 individuals underwent surveillance for soil-transmitted nematodiasis in Hubei Province from 2016 to 2023, and a total of 262 individuals were detected with soil-transmitted nematode infections, including two cases with mixed infections, yielding an overall prevalence rate of 0.33% (262/80 547). The prevalence rates of hookworm, Ascaris lumbricoides, Trichuris trichiura, and E. vermicularis infections were 0.02% (20/80 547), 0.07% (55/80 547), 0.02% (15/80 547) and 0.22% (174/80 547), respectively, appearing a parasite species-specific prevalence rate (χ2 = 250.235, P < 0.05), and the prevalence rates of soil-transmitted nematode infections were 0.50%(51/10271),0.37%(34/9120),0.39%(39/10099),0.40%(41/10168), 0.36% (37/10 234), 0.45% (46/10 211), 0.03% (3/10 238) and 0.11% (11/10 206) in Hubei Province from 2016 to 2023, respectively, showing a year-specific prevalence rate (χ2 = 60.589, P < 0.05). Soil-transmitted nematode infections were detected across 36 surveillance points, and there was a significant difference in the prevalence of soil-transmitted nematode infections among surveillance points (0.02% to 3.30%, P < 0.001). In addition, the differences in prevalence rates of human soil-transmitted nematode infection among different age groups (χ2 = 531.091, P < 0.05), occupations (P < 0.001), and education levels (P < 0.001) were all statistically significant. Among these, the children at ages of 3 to 9 years old (1.40%, 174/12 461), nursery-school children (1.69%, 90/5 312) and preschool-aged children (1.56%, 93/5 969) were relatively high. Conclusions The overall prevalence of soil-transmitted nematodiasis was low in Hubei Province from 2016 to 2023; however, the prevalence varied across regions and among populations, with E. vermicularis as the predominant species of soil-transmitted nematode. Soil-transmitted nematodiasis control should be given a high priority in key areas in Hubei Province, and preschool children, primary school students, and individuals with a low educational level are recommended as key target populations for health education and interventions.

Countries in the Southeast Asian region have revised their national food-based dietary
guidelines (FBDGs) in response to the public health and nutrition priorities. As a continuous
effort to facilitate regional networking, the Southeast Asia Public Health Nutrition Network
publishes this review as an update of its previous publication in 2016. This review provides
an updated descriptive overview of current FBDGs for the general adult population in Brunei
Darussalam, Indonesia, Malaysia, the Philippines, Thailand, and Vietnam. It summarises
and compares commonalities and differences in key dietary messages and visual
communication tools across countries. The findings indicate strong regional alignment on
core dietary recommendations, including consuming a balanced and varied diet with foods
from all food groups, prioritising vegetables and fruits, prioritising minimally processed
grains or whole grains starchy staples, practising moderation in protein intake from both
animal and plant sources, limiting foods high in fats/oils, sugar and salt, being physically
active and maintaining a healthy body weight. Pictorial food guides, such as food pyramids
and healthy plates, are widely used, with variations in design that reflect cultural contexts
to enhance public understanding. While countries acknowledge the importance of FBDGs,
effective dissemination and adoption remain challenging due to limited resources, weak
cross-sectoral collaboration, and unsupportive food environments. This review highlights
the need for stronger communication strategies, improved understanding of consumer
barriers, systematic monitoring and evaluation, inclusion of guidance on away-from-home
meals, strengthened multi-stakeholder collaboration across the food supply chain, and
enhanced regional collaboration to support effective FBDGs implementation in Southeast
Asia.

Objective:To analyze the clinicopathological characteristics and prognostic factors of patients with Castleman disease (CD).Methods:A retrospective case-series study was conducted. A total of 85 patients newly diagnosed with CD in the First Affiliated Hospital of Air Force Medical University between July 2007 and August 2024 were collected. Their clinical characteristics and prognostic factors were analyzed.Results:Among the 85 patients, 45 had unicentric Castleman disease (UCD) and 40 had multicentric Castleman disease (MCD). In the UCD group, females were more commonly affected (64.4%, 29/45), with a median age of onset of 39 years. The primary lesions were mainly located in the retroperitoneum, neck, abdomen, and axilla; and the hyaline vascular subtype was the predominant pathological type (69.4%, 25/36). In the MCD group, males were more frequently affected (62.5%, 25/40), with a median age of onset of 50 years; and the plasmacytic subtype was the main pathological type (68.2%, 15/22). Compared with UCD patients, MCD patients presented more systemic symptoms and signs [85.0% (34/40) vs. 13.3% (6/45), χ2 = 43.66, P < 0.001], splenomegaly [42.5% (17/40) vs. 2.2% (1/45), χ2 = 20.58, P < 0.001], hepatomegaly [25.0% (10/40) vs. 0 (0/45), χ2 = 10.46, P = 0.001], edema or effusion in serous cavity [67.5% (27/40) vs. 8.9%(4/45), χ2 = 31.40, P < 0.001], hematological system involvement [32.5% (13/40) vs. 0 (0/44), χ2 = 16.92, P < 0.001], and renal involvement [22.5% (9/40) vs. 2.3%(1/44), χ2 = 6.36, P = 0.012]. Laboratory findings showed that the levels of hemoglobin and albumin in MCD patients were lower than those in UCD patients, while white blood cell count in MCD patients was higher than that in UCD patients. Additionally, MCD patients exhibited elevated levels of C-reactive protein, interleukin-6, vascular endothelial growth factor, erythrocyte sedimentation rate, and ferritin compared to UCD patients (all P < 0.05). Among UCD patients, 40 cases underwent simple surgical resection, with no deaths during follow-up and the 5-year overall survival (OS) rate of 100.0%; among MCD patients, 34 cases received chemotherapy, 4 received siltuximab, 3 died during follow-up with a 5-year OS rate of 87.5%; and there was no statistically significant difference in OS between the MCD and UCD groups ( χ2 = 3.67, P = 0.055). Among MCD patients, the OS of those with renal involvement (9 cases) was worse than that of those without renal involvement (31 cases) ( χ2 = 8.39, P = 0.004). Conclusions:CD is a highly heterogeneous disorder. Surgical resection is the primary treatment for UCD, with a favorable prognosis. Chemotherapy is the main treatment for MCD, with a relatively poor prognosis.

Nitrofurantoin(NFT)is a nitrofuran antibiotic commonly used as a veterinary drug to treat bacterial infections in animals.However,due to the low solubility and bioaccumulation properties,NFT is prone to leave excessive residues in animal-derived foods and water systems,posing serious threats to human health and ecosystems.Therefore,there is an urgent need to develop an efficient and rapid detection method for NFT.In this work,nitrogen-doped carbon nanomaterials with unique bowl-like structures(N-CNBs)were synthesized via a hydrothermal-carbonization method.The morphology,surface structure,and specific surface area of N-CNBs were characterized using transmission electron microscopy(TEM),scanning electron microscopy(SEM),and X-ray photoelectron spectroscopy(XPS).The N-CNB modified glassy carbon electrode(N-CNB/GCE)was prepared,and the electrochemical test revealed that the N-CNB/GCE exhibited higher conductivity and larger electrochemical active surface area compared to bare GCE and nitrogen-doped hollow carbon nanosphere-modified electrode(N-HCNS/GCE).Additionally,the N-CNB/GCE demonstrated superior electrocatalytic activity toward NFT.An NFT electrochemical sensor was constructed based on N-CNB/GCE.The detection conditions of the sensor were optimized,and differential pulse voltammetry(DPV)was employed for NFT detection under optimal experimental conditions.The established NFT electrochemical sensor had a wide linear range of 0.4-500 μmol/L,a low detection limit(S/N=3)of 0.015 μmol/L and high selectivity,with excellent stability and reproducibility.The practical feasibility of this sensor was confirmed by analysis of NFT in milk and tap water samples,with spiked recoveries ranging from 94.2%to 108.9%.

Glucose-6-phosphate dehydrogenase(G6PD)deficiency is one of the most common monogenic genetic diseases in the world.China is the high incidence area of this disease.G6PD heterozygote is the main form of G6PD deficiency in females,which belongs to X-linked incomplete dominant inheritance.Therefore,the enzyme activities of female heterozygotes vary widely,showing normal to mild to moderate enzyme activi-ties.There is no unified calibrators for G6PD enzymatic detection reagents commonly used in clinical practice,and the results of the same sample detected by different kits from different manufacturers are different,so there is a phenomenon of missed detection in clinical screening of female G6PD heterozygotes.Although G6PD gene detection can effectively improve the detection rate of female heterozygotes,its clinical application is lim-ited due to cost and other reasons.Therefore,the development of detection methods that can improve the de-tection rate of female heterozygotes and are suitable for large-scale screening and clinical application will be an urgent need to be solved in clinical practice.This article reviews the epidemiology of G6PD deficiency,genetic characteristics of female G6PD gene,clinical manifestations and detection methods of G6PD female heterozy-gotes.
