Background Climate change poses a significant threat to public health. In China, relevant health intervention research is still in its early stages, and evidence for evaluating the effectiveness of regional climate change health adaptation strategies and measures is scarce. Objective To investigate the level of climate change-related health literacy among residents in Shenzhen, implement targeted health interventions, and assess the intervention effects as well as their influencing factors. Methods From July 2023 to January 2024, 4 communities were randomly selected in Shenzhen, and a total of 896 community residents were enrolled and divided into an intervention group (444 participants) and a control group (452 participants). Baseline and follow-up surveys on climate change-related health literacy were conducted among residents for both groups. During the period between the two surveys, the intervention group received targeted health interventions. Health literacy—comprising 3 dimensions: basic health knowledge and concepts, basic health skills, and healthy lifestyles—was defined as achieving ≥80% of the total score. A differences-in-differences model was adopted to analyze the impact of the intervention, and multiple linear regression was used to explore the factors influencing the intervention effect. Results The baseline survey showed that 240 out of the 896 surveyed residents (26.79%) possessed climate change health literacy. For the 3 dimensions, the number of residents and the proportions with corresponding literacy in descending order were: basic health skills (521, 58.15%), healthy lifestyles (345, 38.50%), and basic health knowledge and concepts (44, 4.91%). After the intervention, the intervention group showed a 3.19% increase in the total health literacy score, a 3.55% increase in basic health knowledge and concepts, and a 4.24% increase in basic health skills (t=2.79, 2.77, and 2.47 respectively) (P<0.05). No significant change was observed in healthy lifestyle scores (t=0.70, P>0.05). Further analysis showed that awareness of the “dual carbon goals” and occupation were significantly associated with the intervention effect on overall health literacy (P<0.05). For basic health knowledge and concepts, occupation, history of chronic diseases, and awareness of the “dual carbon goals” had statistically significant effects on the intervention outcomes (P<0.05). Regarding basic health skills, awareness of the “dual carbon goals” significantly influenced the intervention effect (P<0.001). In terms of healthy lifestyles, gender, educational level, occupation, and awareness of climate change were significantly associated with the intervention effect (P<0.05). Conclusion The climate change-related health literacy among community residents in Shenzhen is in urgent need of improvement. Health interventions can effectively enhance residents' basic health knowledge and concepts, basic health skills, and overall literacy level. In the future, it is necessary to strengthen the popularization of climate change health knowledge based on different population characteristics and further optimize intervention strategies, to comprehensively improve residents' health adaptation capacity to climate change.

Objective:To explore the association between the metabolic score for insulin resistance (METS-IR) and metabolic dysfunction-associated fatty liver disease (MAFLD), and to compare the diagnostic ability of METS-IR with the fatty liver index (FLI) and hepatic steatosis index (HSI) for MAFLD.Methods:This cross-sectional study enrolled 551 individuals participating in community health screenings in Suzhou between September and November 2022. Data collected included basic demographics, clinical indicators, and iLivTouch? (FibroTouch FT5000, Wuxi Hisky Medical Technologies, China) transient elastography results. Participants were categorized into non-MAFLD ( n=218) and MAFLD ( n=333) groups based on an ultrasound attenuation parameter (UAP) cutoff of 244 dB/m measured by iLivTouch. Logistic regression and restricted cubic spline (RCS) analyses were employed to assess the relationship between METS-IR and MAFLD. The diagnostic value of METS-IR was evaluated using receiver operating characteristic (ROC) curves. DeLong′s test was used to compare the diagnostic performance of the different indices. Results:Among the 551 participants, the prevalence of MAFLD diagnosed by transient elastography was 60.4% (333/552). Compared to the non-MAFLD group, the MAFLD group had significantly higher levels of BMI, SBP, DBP, HbA1c, FPG, 2hPG, TC, TG, LDL-C, ALT, AST, GGT, SUA, liver stiffness measurement (LSM), METS-IR, FLI, and HSI, while HDL-C levels were lower (all P<0.05). The MAFLD group also had a higher prevalence of males, overweight/obesity, smoking, hypertension, pre-diabetes, dyslipidemia, hyperuricemia, metabolic syndrome, and antihypertensive medication use (all P<0.05). Multivariate logistic regression analysis, after adjusting for gender, age, smoking, alcohol consumption, hypertension, diabetes, dyslipidemia, hyperuricemia, ALT, AST, and GGT, demonstrated that METS-IR, FLI, and HSI remained significantly associated with an increased risk of MAFLD ( OR=1.148, 1.042, 1.270, respectively; all P<0.001). The areas under the ROC curve for METS-IR, FLI, and HSI in diagnosing MAFLD were 0.733 (95% CI: 0.691-0.774), 0.727 (95% CI: 0.685-0.770), and 0.677 (95% CI: 0.632-0.722), respectively. The sensitivities were 57.40%, 62.20%, and 48.30%; specificities were 78.00%, 72.90%, and 78.40%; and optimal cutoff values were 38.526, 35.225, and 35.386, respectively. DeLong′s test indicated no significant difference in diagnostic performance between METS-IR and FLI ( P=0.722). However, both METS-IR and FLI demonstrated significantly better diagnostic performance than HSI ( P=0.008 and P=0.018, respectively). Conclusion:METS-IR is significantly associated with MAFLD and effectively identifies MAFLD in community settings. Its diagnostic performance is comparable to FLI and superior to HSI.

With the widespread use of antimicrobial agents, bacterial drug resistance has become an increasingly severe issue, posing significant challenges to global healthcare. Traditional Chinese medicine (TCM) has emerged as a research focus in the field of bacterial resistance due to its broad sources, high safety profile, low toxicity, and antimicrobial mechanisms distinct from those of chemical drugs. Studies have shown that various TCM herbs, such as Scutellaria baicalensis, exert antibacterial effects through multiple pathways, including disrupting the integrity of bacterial cell walls and membranes, inhibiting nucleic acid and protein synthesis, and impairing energy production and metabolism. Additionally, certain TCM herbs, including Scutellaria baicalensis, Coptis chinensis, and Fritillaria thunbergii, can reverse antimicrobial resistance by eliminating resistant plasmids, inhibiting bacterial efflux pump function, and suppressing β-lactamase activity. TCM holds promising potential for antibacterial applications and synergistically reversing antimicrobial resistance, though systematic analyses remain limited. This review summarizes the mechanisms of antibacterial action of TCM and current research on its synergistic use with antimicrobial agents to reverse drug resistance, aiming to provide insights for developing novel TCM-based antimicrobials and addressing bacterial resistance.

Objective To identify long non-coding RNA (lncRNA) associated with rheumatoid arthritis-associated interstitial lung disease (RA-ILD) and investigate their mechanisms. Methods Peripheral blood samples were collected from RA-ILD patients (n=3), RA patients without lung involvement (n=3), and healthy controls (n=3). Next-generation sequencing was performed to screen differentially expressed lncRNA. A human fibrotic lung cell model was established by inducing the MRC-5 cell line with transforming growth factor-β (TGF-β). Following siRNA-mediated knockdown of target genes, changes in inflammatory and oxidative stress-related genes were analyzed via real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR). Western blotting and dual-luciferase reporter (DLR) assays were used to validate protein expression, ubiquitination levels, and nuclear translocation of oxidative stress regulators, and antioxidant response element (ARE) transcriptional activity. Rescue experiments were conducted to confirm the role of target lncRNA in oxidative stress and inflammation in fibrotic lung cells. Results High-throughput sequencing revealed significant downregulation of LINC00638 in RA-ILD patients. Knockdown of LINC00638 markedly reduced transcriptional levels of interleukin (IL)-4, nuclear factor erythroid-2-related factor 2 (Nrf2), heme oxygenase-1 (HO-1), and superoxide dismutase 2 (SOD2), while increasing IL-6, IL-1β, interferon-γ (IFN-γ), and reactive oxygen species (ROS) levels. Furthermore, LINC00638 knockdown decreased Nrf2 protein expression, increased its ubiquitination, reduced nuclear translocation, and suppressed ARE transcriptional activity. In MRC-5 cells, LINC00638 knockdown combined with N-acetylcysteine treatment restored Nrf2 and HO-1 levels while reducing IL-6 expression. Conclusions LINC00638 suppresses inflammatory responses in RA-ILD by activating the Nrf2/ARE antioxidant signaling pathway, suggesting its potential as a therapeutic target for diagnosis and treatment.

OBJECTIVES:
To investigate the correlation of PRELID1 with gastric cancer (GC) progression, prognosis, and epithelial-mesenchymal transition (EMT) and the underlying mechanisms.
METHODS:
We analyzed the data of 115 patients undergoing radical gastrectomy for GC in our hospital between February, 2018 and March, 2023 to explore the correlation of PRELID1 expression level in GC tissues with tumor progression and patient prognosis. In cultured GC cells, the effects of lentivirus-mediated overexpression or interference of PRELID1 were observed on cell migration, invasion and EMT.
RESULTS:
Immunohistochemical staining revealed significantly higher PRELID1 expression in GC tissues (P<0.001), whose expression level was positively correlated with CEA ≥5 ng/mL (P=0.007), CA199 ≥37 U/mL (P=0.007), G3-4 stages (P=0.001), T3-4 stages (P=0.001), and N2-3 stages (P=0.020). Univariate and Cox multifactorial analysis showed that high PRELID1 level was an independent risk factor affecting 5-year survival of GC patients (P=0.001). In cultured GC cells, PRELID1 overexpression obviously promoted cell proliferation, migration, invasion, and the expressions of MMP2 and MMP9, and interference of PRELID1 produced the opposite changes. PRELID1 overexpression also increased the expressions of N-cadherin and vimentin and reduced the expression of E-cadherin. Mechanistic analyses showed that up-regulation of PRELID1 increased the expression of p-PI3K, p-AKT, and p-mTOR in GC cells, whereas its interference caused the opposite changes; the application of 740 Y-P, a PI3K/AKT pathway activator, significantly enhanced the migration, invasion, and EMT of GC cells with PRELID1 knockdown.
CONCLUSIONS
PRELID1 is highly expressed in GC and affects prognosis of the patients, and its high expression promotes migration, invasion and epithelial mesenchymal transition of GC cells possibly by activating the PI3K/AKT/mTOR pathway.

Objective:To investigate the protective effects of Mailuoning(MLN)against cisplatin(CP)-induced acute kidney injury(AKI)utilizing network pharmacology and to analyze the underlying mechanism of action related to anti-apoptotic pathways.Methods:Active components of MLN and targets related to AKI were identified using network pharmacology.The active components of MLN were sourced from the TCMSP and ETCM 2.0 databases.The targets of components were predicted using the Swiss Target Prediction tool,and subsequently the targets related to AKI were retrieved from the GeneCards database to identify intersecting targets.A protein-protein interaction network was constructed using the STRING database,and a topological analysis was performed using Cytoscape to identify core targets.Gene Ontology(GO)functional annotation and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway en-richment analyses were conducted on these core targets.For the animal experiments,forty mice were randomly assigned to four groups:solvent control,MLN toxicity control,CP model,and CP+MLN groups.The MLN group received intraperitoneal injections of MLN at a dose of 15 mL/(kg·d)for ten consecutive days.The CP model and CP+MLN groups were administered a single intraperitoneal injec-tion of CP at 20 mg/kg on day 7.Three days after the CP treatment,plasma levels of blood urea nitrogen(BUN)and creatinine(Cre)were measured.The pathological injury of kidney tissues was as-sessed using hematoxylin-eosin staining.Western blot analysis was utilized to determine the expression of neutrophil gelatinase-associated lipocalin(NGAL)and apoptosis-related proteins in kid-ney tissues.Results:A total of 104 active components of MLN and 224 targets were identified using network pharmacology,and 2 465 targets were identified to be related to AKI,resulting in 117 intersecting targets,of which,17 targets were classified as core targets.KEGG and GO analyses indicated that the apoptosis-related signal transduction pathway might be a crucial pathway through which MLN provided protective effects against AKI.The results of animal experiments confirmed the successful establishment of CP-induced AKI models in mice.Compared with the CP model group,MLN treatment significantly reduced plasma levels of BUN and Cre(P<0.05),inhibited NGAL protein expression in the kidneys(P<0.05),and improved the pathological injury observed in kidney tissues.Furthermore,MLN markedly reduced the expression levels of p-P53(ser 15)and cleaved caspase-3 proteins,as well as the Bax/Bcl-2 ratio in kidney tissues of AKI model mice(P<0.05),while upregulating protein kinase B phosphorylation levels(P<0.05).Conclusion:MLN demonstrates protective effects against CP-induced AKI in mice,potentially through mechanisms related to its anti-apoptotic properties.
