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.

ObjectiveTo explore the long-term dynamic trajectories of fasting blood glucose (FBG) and insulin resistance (IR) in patients with type 2 diabetes mellitus (T2DM) and their influencing factors. MethodsThis retrospective cohort study included 1 896 T2DM patients registered at Tongren Hospital from May 2020 to May 2025. Based on longitudinal follow-up data of FBG and fasting insulin, joint latent class mixed models (JLMM) were applied to identify FBG-IR trajectories. Univariate and multinomial logistic regression was used to examine demographic characteristics, lifestyle, and clinical determinants of trajectory type. ResultsFour distinct FBG-IR trajectories were identified: stable FBG-IR (9.76%), rising FBG-stable IR (5.01%), stable FBG-elevated IR (75.90%), and elevated FBG-IR (9.34%). Compared with the stable FBG-IR group, age ≥60 years was protective against the elevated FBG-stable IR trajectory (OR=0.55, 95%CI:0.33-0.92, P=0.023). Highereducation increased the risk of stable FBG-elevated IR (OR=1.40, 95%CI:1.01-1.94, P=0.046). Abnormal blood pressure was associated with lower risks of stable FBG-elevated IR (OR=0.66, 95%CI:0.48-0.92, P=0.013) and elevated FBG-IR (OR=0.48, 95%CI:0.31-0.74, P=0.001). Non-drinkers were less likely to belong to the stable FBG-elevated IR trajectory (OR=0.39, 95%CI:0.16-0.95, P=0.038). ConclusionsThe evolution trajectory of FBG and IR in T2DM patients shows significant heterogeneity. The majority of patients have a deterioration of IR first. Age, education level, blood pressure, and alcohol consumption are the main influencing factors. Joint assessment of FBG and IR is helpful for early identification of high-risk individuals and guiding individualized intervention.

OBJECTIVE To evaluate the quality of Lufu Pill (LFP).METHODS The high-performance liquid chromatography (HPLC) fingerprint of LFP was established using the Similarity Evaluation System for Chromatographic Fingerprint of Traditional Chinese Medicine (2012 Edition), and similarity evaluation was performed. Hierarchical cluster analysis (HCA), principal component analysis (PCA), and orthogonal partial least squares-discriminant analysis (OPLS-DA) were performed using SIMCA 14.1 software. The contents of strychnine, brucine, liquiritin, notoginsenoside R 1 , ginsenoside Rg 1 , ginsenoside Rb 1 , licoricesaponin G 2 , and ginsenoside Rd in 12 batches of samples were determined by the HPLC method.RESULTS A total of 26 common peaks were identified in the HPLC fingerprint of 12 batches of LFP samples, and eight common peaks were identified as strychnine (peak 3), brucine (peak 4), liquiritin (peak 6), notoginsenoside R 1 (peak 7), ginsenoside Rg 1 (peak 8), ginsenoside Rb 1 (peak 15), licoricesaponin G 2 (peak 17), and ginsenoside Rd (peak 18). The similarities of 12 batches of LFP samples were all greater than 0.90. The results of HCA and PCA both showed that the 12 batches of samples were divided into two categories: S2, S4-S6, and S12 were grouped into one category, while S1, S3, S7-S11 were grouped into another category. The upper control limits for Hotelling’s T 2 and DMod X were 16.631 and 1.578, respectively. The variable importance in projection values of ginsenoside Rg 1 (peak 8), ginsenoside Rb 1 (peak 15), peak 20, strychnine (peak 3), peak 11, notoginsenoside R 1 (peak 7), peak 2, peak 17, peak 13, peak 10, ginsenoside Rd (peak 18), peak 23, peak 26, peak 21, and peak 24 were greater than 1.The content determination results showed that strychnine, brucine, liquiritin, notoginsenoside R 1 , ginsenoside Rg 1 , ginsenoside Rb 1 , licoricesaponin G 2 , and ginsenoside Rd were 0.005%-0.018%, 0.005%-0.010%, 0.050%-0.118%, 0.033%-0.073%, 0.132%-0.248%, 0.122%-0.242%, 0.021%-0.043%, and 0.016%-0.048%, respectively.CONCLUSIONS The established HPLC fingerprint and content determination method are accurate and reproducible, and can be used for the quality evaluation of LFP. Ginsenoside Rg 1 , ginsenoside Rb 1 , strychnine, notoginsenoside R 1 , and ginsenoside Rd may be the differential components affecting its overall quality.

Objective:To analyze the carriage status, subtype distribution and flanking gene sequence characteristics of oxacillinases (OXA enzyme) in 241 clinical strains of Pseudomonas aeruginosa, and assess their roles in the drug resistance of Pseudomonas aeruginosa and ability to horizontally transfer across species. Methods:Clinical P. aeruginosa isolates were collected from four hospitals in Sanya, Tangshan, Zhangjiakou, and Beijing. The prevalence of oxacillinases and their flanking gene sequences was analyzed by whole-genome sequencing (NGS) and bioinformatic approaches. Results:A total of 241 isolates of P. aeruginosa were gathered, and 35 blaOXA subtypes were identified through screening of 252 blaOXA genes. These genes were classified into three subfamilies: blaOXA-50-like (241, 95.6%), blaOXA-1-like (9, 3.6%) and blaOXA-10-like (2, 0.8%). Among these, 11 subtypes (11, 31.4%) were novel blaOXA subtypes. Nine of these belonged to the blaOXA-50-like subfamily and were designated as blaOXA-1244, blaOXA-1245, blaOXA-1246, blaOXA-1250, blaOXA-1252, blaOXA-1253, blaOXA-1254, blaOXA-1255, and blaOXA-1256. The remaining two belonged to the blaOXA-10-like subfamily and were named blaOXA-1247 and blaOXA-1248. Compared to the amino acid sequence of OXA-10, the newly identified subtype OXA-1247 exhibited a mutation at position 117, where a valine was replaced by a leucine. This change was thought to improve the enzyme′s ability to hydrolyze carbapenems. In the analysis of the flanking sequences of the blaOXA genes, Class I integrons were identified in four bacterial strains. The variable regions of these integrons carried three distinct patterns of resistance gene cassettes: aac( 6′) -Ib-blaOXA-1247-ant( 3′′) -Ia, aac( 6′) -Ib-blaOXA-1248 and aac( 6′) -Ib- blaIMP-45-blaOXA-1-catB3. Among these, the strain BJ2326 carried a class I integron that was connected to the downstream IS CR1 element to form a composite class I integron structure, additionally carrying the resistance gene blaPER-1. Out of the 223 non-wild-type P. aeruginosa strains, 127 strains exhibited non-wild-type profiles to the four beta-lactam antibiotics MEM, CAZ, FEP, and TZP, with the combination of MEM+CAZ+FEP being the most prevalent, representing 57.0% of the total. Conclusions:The blaOXA genes in 241 clinical P. aeruginosa strains showed diversity. Some blaOXA genes had a co-transfer risk with the metallo-β-lactamase resistance gene blaIMP-45. Among the 11 newly discovered blaOXA subtypes, the new subtype OXA-1247 may have carbapenemase activity and potential for horizontal transfer.

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.
