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.

ObjectiveTo integrate network pharmacology prediction with multi-level experimental verification methods, and to explore in depth the therapeutic efficacy and potential mechanism of luteolin in treating gout. MethodsDatabases were used to obtain potential pharmacodynamic targets of luteolin. Protein-protein interaction (PPI) network construction and network pharmacology analysis techniques were used to screen key core targets of luteolin in gout treatment. Further biological function enrichment analysis and signaling pathway analysis were performed on these targets. Molecular docking simulation was used to calculate the binding energy between luteolin and potential core targets, clarifying the strength of their interactions. In the in vivo experiment for hyperuricemia, 48 mice were randomly divided into a blank group, a model group, an allopurinol group (5 mg·kg-1), and low-dose (10 mg·kg-1), medium-dose (30 mg·kg-1), and high-dose (90 mg·kg-1) luteolin groups. For the first three days, the blank and model groups were gavaged with an equal volume of normal saline, while the allopurinol group and luteolin groups were gavaged with corresponding drugs. From day 4 onwards, modeling was performed by intraperitoneal injection at 12:00 daily (normal saline for the blank group, and oxonic acid potassium-hypoxanthine mixture for other groups, with 300 mg·kg-1 for each group). Gavage intervention was administered at 18:00 daily (normal saline for the blank/model groups, and corresponding drugs for the treatment groups) until day 7. After sampling, levels of serum uric acid (UA), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) were measured. Levels of xanthine oxidase (XO) in the liver and kidney, ATP-binding cassette transporter G2 (ABCG2) and malondialdehyde (MDA) in the kidney, and superoxide dismutase (SOD) in the liver were determined. Renal HE staining was also performed. In the pharmacodynamic study of gouty arthritis, 36 rats were randomly divided into a blank group, a model group, a colchicine group (0.315 mg·kg-1), and low-dose (7 mg·kg-1), medium-dose (21 mg·kg-1), and high-dose (63 mg·kg-1) luteolin groups. The model was established by vertically injecting 100 µL of 25 g·L-1 monosodium urate suspension into the posterior lateral aspect of the right ankle joint (the blank group was injected with an equal volume of normal saline), with repeated injections every two days for reinforcement. From day 2 after modeling, daily gavage administration was performed (normal saline for the blank/model groups, and corresponding drugs for the treatment groups) for a total of 16 days. During the experiment, ankle swelling and pain threshold were measured regularly. After sampling, levels of serum tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-1β (IL-1β) were determined. Ankle joints were subjected to HE, Masson, and safranin O-fast green staining, and HE staining was also performed on ankle synovial tissue and various organs. Western blot was used to determine the expression levels of key proteins in gout-related signaling pathways. ResultsNetwork pharmacology analysis predicted that luteolin may regulate over 20 core targets, such as XO, ABCG2, nuclear factor erythroid 2-related factor 2 (Nrf2), and SOD, through acting on signaling pathways including NF-κB, phosphoinositide 3-kinase/protein kinase B (PI3K/Akt), and ABC transporters, thereby affecting uric acid metabolism and inflammatory responses. In the hyperuricemia model, compared with the blank group, the model group showed significantly increased serum UA level, liver and kidney XO activity, renal ABCG2 expression, and liver SOD activity (P<0.01). Compared with the model group, the high-dose luteolin group significantly reduced serum UA level (P<0.01), inhibited liver and kidney XO activity (P<0.01), and significantly increased renal ABCG2 expression and liver SOD activity (P<0.01), effectively alleviating renal oxidative stress damage and improving renal histopathological status. In the gouty arthritis model, compared with the blank group, the model group showed significant ankle swelling, decreased pain threshold, and significantly increased levels of IL-6, IL-1β, and TNF-α in serum and synovial tissue (P<0.01). The high-dose luteolin group significantly reduced ankle swelling, prolonged hot plate pain threshold, effectively decreased the levels of the above inflammatory factors in serum and synovial tissue (P<0.01), and significantly improved ankle pathological damage, showing good analgesic and anti-inflammatory effects. Western blot results further confirmed that luteolin significantly upregulated Nrf2 protein expression and downregulated XO and nucleotide-binding oligomerization domain (NOD)-like receptor protein 3 (NLRP3) expression in animals. ConclusionLuteolin can improve symptoms of hyperuricemia and gouty arthritis, and its potential mechanism may be related to inhibiting XO activity, increasing ABCG2 and SOD levels, and regulating Nrf2-mediated oxidative stress-related pathways.

Stroke is the leading cause of death and disability among adults in China, and its common complications include digestive system abnormalities, cognitive impairment, depression, stroke-associated pneumonia, and hemiplegia. The combination of traditional Chinese and Western medicine has great potential in treating post-stroke complications. Xinglou Chengqitang (XLCQT) is a representative prescription of alleviating the disease in the upper part by treating the lower part. It has definite therapeutic effect and high safety. Clinically, XLCQT is often used to treat stroke and its complications. However, the quantity and quality of clinical trials of XLCQT in treating post-stroke complications need to be improved. Additionally, since the basic research is weak, the material basis and multi-target mechanism for the efficacy of this prescription are unknown. This article reviews XLCQT in terms of the pharmacodynamic basis, medicinal properties, safety evaluation, and progress in clinical research and mechanisms in treating post-stroke complications. This article summarizes 22 key active ingredients of XLCQT in treating acute stroke complicated with syndrome of phlegm heat and fu-organ excess. Among these key active ingredients, resveratrol, kaempferol, luteolin, chrysoeriol, apigenin, (+)-catechin, and adenosine have good pharmacokinetic properties and high bioavailability. The mechanisms of XLCQT in treating post-stroke complications are complex, including inflammatory response, brain-gut axis, hypothalamic-pituitary-adrenal (HPA) axis, intestinal flora, neurotrophic factors, autophagy, oxidative stress, and free radical damage. This review helps to deeply understand the pharmacodynamic basis and mechanisms of XLCQT in treating post-stroke complications and provides a theoretical basis for the clinical application of XLCQT against post-stroke complications and the development of drugs.

ObjectiveObesity, a global chronic metabolic disease, is closely associated with disruptions in lipid metabolism and gut microbiota. Current intervention strategies still have limitations in terms of safety and microecological regulation, necessitating the exploration of novel natural regulatory approaches. Based on the early pathological characteristics of obesity, this study innovatively employs a rectal delivery method alongside a high-fat diet (HFD)-induced obesity model to systematically evaluate the inhibitory effects, safety, and gut microbiota regulation mechanisms of leek-derived and konjac-derived extracellular vesicles on obesity development. By simulating early clinical intervention scenarios, this study aims to explore the preventive potential of plant-derived extracellular vesicles during the initial stages of obesity onset. MethodsExtracellular vesicles from leek and konjac were isolated using ultracentrifugation combined with density gradient centrifugation. Their nanoscale properties were characterized by dynamic light scattering (DLS), transmission electron microscopy (TEM), and nanoparticle tracking analysis (NTA). Male C57BL/6J mice were randomly divided into four groups: normal control (NC), high-fat diet (HFD), leek-derived extracellular vesicles (LEVs), and konjac-derived extracellular vesicles (KEVs). Beginning simultaneously with HFD feeding, mice in the intervention groups received 20 g/L vesicles rectally every 3 d for 4 weeks. Body mass and body composition were monitored throughout. At endpoint, mouse serum, adipose tissue, and colonic contents were collected. Serum biochemical indices (lipid profile, liver and kidney function, cardiac markers) were assessed to evaluate safety and metabolic efficacy, while 16S rRNA sequencing was employed to analyze gut microbial structure and diversity. ResultsDLS, NTA, and TEM confirmed that both LEVs and KEVs exhibited typical cup-shaped nanostructures with average particle sizes of approximately 284 nm and 223 nm, respectively. LEVs and KEVs treatment significantly suppressed HFD-induced weight gain and elevation of body-fat percentage (P<0.05), and reduced accumulation of abdominal white and epididymal adipose tissue. Serological analyses showed that both vesicles lowered total cholesterol, triglycerides and LDL-cholesterol, and ameliorated liver enzyme profiles (ALT, AST), demonstrating lipid-metabolic regulation and hepatoprotective effects. No hepatic, renal or cardiac dysfunction was observed, indicating favorable safety. Gut microbiota analyses revealed that vesicle intervention partially restored HFD-depleted microbial diversity and reshaped community structure. Notably, LEVs markedly increased the relative abundance of the beneficial taxon Lachnospiraceae at the family level, which is known for producing short-chain fatty acids and enhancing intestinal barrier function. Furthermore, Phylogenetic Investigation of Communities by Reconstruction of Unobserved States (PICRUSt) functional prediction suggested that LEVs and KEVs modulated gut microbial functions through distinct mechanisms: LEVs downregulated pathways related to ribosomes and DNA replication while enhancing xenobiotic degradation, whereas KEVs tended to upregulate energy metabolism and protein synthesis toward healthy levels. ConclusionRectally administered LEVs and KEVs exhibit excellent safety and pronounced metabolic benefits during the early phase of obesity, suppressing weight gain, correcting lipid dysregulation, and exerting effects via modulation of gut microbial composition and function. This study provides systematic experimental evidence supporting plant-derived exosome-like vesicles as an early intervention strategy against obesity.

Introduction:
Adequate knowledge of diabetes is essential for effective self-management and glycemic control. Emerging trends in
digital platforms, video-based education offer a scalable and accessible approach to patient learning. However, evidence
on the effectiveness of validated YouTube-based diabetes education in the Malaysian population remains limited. We
aimed to evaluate the impact of a newly developed, tri-language YouTube diabetes education programme on clinical and
knowledge outcomes.
Methodology:
In this multicentre study, patients with diabetes mellitus were randomly assigned to intervention (YouTube-based education)
and control groups (standard care). The intervention consisted of newly developed and validated short educational videos
on YouTube regarding diabetes, complications and lifestyle changes, delivered weekly via WhatsApp over 9 weeks. Videos
were available in English, Malay and Chinese. The control group received standard care and counseling. Demographic
data, hemoglobin A1c (HbA1c), and knowledge scores were collected at baseline and 3 months post-intervention.
Results:
A total of 109 patients (62.4% female; mean age 53.2 years; mean diabetes duration 16.3 years) were enrolled in the
study, with similar baseline characteristics between groups. The intervention group demonstrated significantly greater
improvement in glycemic control compared to the control group (HbA1c: −1.22 ± 1.36% vs. −0.24 ± 1.05%; p <0.001). While
knowledge scores improved in both groups, the increase was significantly greater in the intervention group (2.66 vs. 0.80;
p = 0.001). Notably, improvement in knowledge score predicted HbA1c reduction (b = 0.091; 95% CI 0.01, 0.172; p = 0.028).
Conclusion
The tri-language YouTube-based diabetes education programme significantly improved both glycemic control and patients’
knowledge. This accessible, scalable video-based education represents an effective strategy to enhance diabetes selfmanagement, offering flexible, on-demand learning for diverse populations.

Alcohol is a high-risk factor of the head and neck tumor, and acetaldehyde dehydrogenase type 2(ALDH2) is an important alcohol metabolism enzyme in the human body, whose function is to metabolize acetaldehyde into non-toxic acetic acid in the human body. Studies have shown that ALDH2 gene polymorphisms increase the risk of head and neck tumors by affecting enzyme activity to regulate the rate of alcohol metabolism in the body, and high levels of ALDH2 expression are beneficial for enhancing head and neck tumor immunity and improve prognosis. This article aims to review the research progress on the relationship between ALDH2 and the occurrence and treatment of head and neck tumors.
