Animal model research on spleen and stomach diseases in traditional Chinese medicine （TCM） is of great significance for elucidating the nature of diseases and syndromes and for revealing the mechanisms of action of Chinese herbal medicinals. At present， studies on classical TCM syndrome models of spleen and stomach diseases mainly focus on spleen deficiency syndrome， liver constraint syndrome， and damp-heat syndrome. Model construction is mostly based on the etiological and pathophysiological characteristics of syndrome， and model evaluation primarily involves macroscopic manifestations and physicochemical indicators. This paper summarizes the current research status of animal models integrating disease and syndrome for seven common spleen and stomach diseases， including chronic gastritis and gastric precancerous lesions， gastroesophageal reflux disease， functional dyspepsia， inflammatory bowel disease， irritable bowel syndrome， functional constipation， and functional diarrhea. The modeling methods and characteristics of disease-syndrome combined animal models for each disease are analyzed. It is proposed that future research on disease-syndrome integration in spleen and stomach diseases should move toward syste-matic， precise， and integrative development， and that interdisciplinary and cross-disciplinary research approaches should be adopted to enhance the predictive value and application efficiency of disease-syndrome combined animal models.

Objective: To explore the relationship between snack consumption and depressive symptoms in first year junior high school students with different left behind experiences in Yunnan Province, so as to provide a basis for improving depressive symptoms among first year junior high school students with different left behind experiences. Methods: From October to December 2022,a cluster random sampling method was used to select 8 500 first year junior high school students from 11 ethnic minority areas (Fugong County, Longling County, Longyang District, Luchun County, Mojiang County, Nanjian County, Qiaojia County, Shuangjiang County, Tengchong City, Yuanmou County, Zhenyuan County) in Yunnan Province for a questionnaire survey. The Chinese version of Depression Anxiety Stress Scale-21 was applied to assess depressive symptoms in first year junior high school students, and snack consumption was collected by employing food frequency questionnaire. The generalized linear model was used to analyze the association between first year junior high school students snack consumption and depressive symptoms, and the analysis was stratified according to left behind experience. Results: The detection rates of depressive symptoms among firstyear junior high school students with and without left behind experience were 36.25% and 26.91%, respectively. After controlling for confounding variables, the generalized linear model analysis showed that sweet snacks ( β=0.16, 95%CI =0.07-0.25), fast food ( β=0.14, 95%CI =0.04-0.23) and carbonated drinks ( β=0.09, 95%CI =0.01-0.17) of first year junior high school students with left behind experience (all P <0.05). Compared with those without such behavior, the risk of depressive symptoms was higher in consumption of fast food ( β=0.13, 95%CI =0.07-0.18) and carbonated drinks ( β=0.10, 95%CI =0.06-0.15)among first year junior high school students without left behind experience (both P <0.05). Conclusion Snack consumption among first year junior high school students in Yunnan may increase the risk of developing depressive symptoms, while first year junior high school students with left behind experience may have a greater risk of developing depressive symptoms.

The prescription of Qidong Yixin oral liquid is derived from the experience of national medical master Ren Jixue in treating viral myocarditis （VMC）. It has the functions of tonifying Qi， nourishing the heart，calming the mind， and relieving palpitations. It is used to treat VMC and angina pectoris of coronary heart disease caused by deficiency of both Qi and Yin. However，the understanding of its efficacy evidence， advantageous aspects， dosage and administration， and medication safety remains insufficient in clinical practice. Therefore，the development of the Expert Consensus on the Clinical Application of Qidong Yixin Oral Liquid （hereinafter referred to as consensus） was initiated. Consensus strictly followed the process and methods of the expert consensus on the clinical application of Chinese patent medicines of the China Association of Chinese Medicine，successively completing multiple tasks such as the consensus project initiation，determination of clinical problems，evidence search and evaluation，formation of recommendation opinions and consensus suggestions，solicitation of opinions，peer review， submission for review and release， and so on.

Neurocritical care involves complex pathophysiological mechanisms, and its incidence is higher, injuries are more severe, and treatment is more challenging in high-altitude environments. This consensus, based on the latest domestic and international evidence-based medical data, establishes a standardized, goal-oriented framework for neurocritical care management applicable in high-altitude regions and nationwide. The consensus was developed following international standards for evidence quality assessment and underwent two rounds of Delphi expert consultation, resulting in 32 recommendation statements covering three parts: management systems, monitoring and assessment, and core strategies. Key updates include: advocating for the establishment of independent neurocritical care units and implementing precise tiered diagnosis and treatment based on the "Five Differences in Critical Care" concept; constructing a "trinity" multimodal brain monitoring system centered on cerebral blood flow, cerebral oxygenation, and brain function, emphasizing routine bedside transcranial Doppler ultrasound, cerebral oximetry, and continuous electroencephalography monitoring; shifting management strategies from mild hypothermia therapy to targeted temperature management, and defining the "446" target management pathway for the supercritical stage; emphasizing the assessment of static and dynamic cerebrovascular autoregulation functions through multimodal methods to achieve individualized optimal mean arterial pressure management; elevating cerebrospinal fluid management goals to the level of "glymphatic system" function maintenance; implementing a multidisciplinary collaborative, whole-process management model focusing on patients' long-term neurological functional outcomes; de-escalation criteria include multidimensional indicators such as recovery of brain structure, restoration of cerebrovascular autoregulation, improvement in cerebrospinal fluid dynamics, and reduction in biomarker levels; and integrating cutting-edge technologies like artificial intelligence into post-critical care management and rehabilitation planning. This consensus systematically integrates the entire process of neurocritical care management, reflecting the modern connotation of goal-oriented, dynamic, and multimodal integration in neurocritical care medicine. It aims to adapt to new trends such as deepening understanding of pathophysiological mechanisms, the integration of medicine and engineering, and the empowerment of artificial intelligence, thereby further advancing the discipline of critical care medicine.

AIM:To analyze the characteristics of pathogenic bacteria in patients with infectious eye diseases at Shangrao Central Hospital from 2020 to 2024, providing a basis for the precise clinical prevention and control and the development of effective strategies.METHODS: A retrospective analysis was carried out on clinical specimens including the cornea, lacrimal duct, conjunctiva, and intraocular fluid samples, from patients with infectious eye diseases between May 2020 and December 2024. All the specimens underwent microbiological cultures and identification.RESULTS: A total of 447 patients enrolled ultimately in this study, including 250 males and 197 females, with an average age of 58.5±17.1 y. Among the 447 ocular specimens, bacterial infection was confirmed in 146 cases(32.7%). Of these positive samples, male patients accounted for 63.7%(93/146)and patients aged 51-70 y had the highest infection rate(88/146, 60.3%). Furthermore, migrant workers represented the predominant demographic affected by ocular infections, accounting for an overwhelming majority at 95.9%(140/146). When compared to other etiologies of disease, trauma emerged as the primary cause of ocular infections(P<0.01). In cases of bacterial ocular infections, Gram-positive cocci comprised approximately 61.2%, with Staphylococcus identified as the principal pathogen affecting the lacrimal duct, conjunctivae, and intraocular fluid. Streptococcus pneumoniae was found to be the main pathogen associated with corneal infections. Gram-negative bacteria were predominantly Pseudomonas aeruginosa. Fungal infections were observed in an alarming rate of 91.8% among corneal specimens. Fusarium was identified as the leading fungal pathogen responsible for these cases at a proportion of 45.9%.CONCLUSION: The distribution of pathogenic bacteria causing ocular infections demonstrates obvious tissue specificity. Trauma is identified as a major inducement of corneal fungal infection. Clinically, it is essential to pay particular attention to patients with ocular trauma, especially those engaged in agricultural labor who present with ocular infections, and fungal tests should be conducted as early as possible.

Objective To systematically analyze the spatiotemporal distribution characteristics and epidemiological trends of tracheal, bronchus, and lung cancer (TBL) disease burden attributed to air pollution globally and in China and the United States from 1990 to 2021, and to assess the patterns of disease burden changes from 2022 to 2031 based on predictive models, providing a scientific basis for formulating targeted TBL prevention and control strategies. Methods Based on the Global Burden of Disease (GBD) 2021 database, we analyzed the disease burden data of TBL attributed to air pollution globally and in China and the United States from 1990 to 2021. R Studio 4.3.2 software was used to analyze the corresponding trends and the Bayesian age-period-cohort (BAPC) prediction model was used to predict the status of the disease burden of TBL attributed to air pollution in the world and in China and the United States from 2022 to 2031. Results In 2021, China had the highest number of deaths and disability-adjusted life years attributed to air pollution (211 400 patients and 4.8947 million person-years), followed by the United States (6 000 patients and 124 300 person-years). The age-standardized mortality rate (ASMR) and age-standardized disability-adjusted life years rate (ASDR) of TBL due to air pollution in the world and in China and the United States showed a decreasing trend. From 1990 to 2021, the ASMR and ASDR of TBL in China due to air pollution were much higher than those in the United States and the global average. In terms of gender, from 1990 to 2021, the disease burden of male patients with TBL attributed to air pollution was much higher than that of female patients. The BAPC prediction model showed that from 2022 to 2031, the ASMR and ASDR of TBL attributed to air pollution showed an upward trend globally, while they showed a downward trend in China and the United States. Conclusion Over the past 30 years, the air pollution-related TBL disease burden in the world and in China and the United States has continued to decline, but China's disease burden is still significantly higher than the global average. The disease burden in men far exceeds that in women, with men and the population aged ≥50 years being high-risk groups. In the future, the global disease trend may reverse and rise, while China and the United States are expected to continuously decline. However, precise prevention and control for high-risk groups remains a key challenge.

Purpose: The aim of this study is to determine the impact of solute carrier family 3 member 2 (SLC3A2) on the malignant phenotype of gliomas and its role in regulating ferroptosis sensitivity. Materials and Methods: The malignant phenotype of glioma was assessed by cell proliferation assay, colony formation assay, EdU assay, wound healing, and Transwell experiments. We further validated the impact of reduced SLC3A2 expression on the sensitivity to ferroptosis in glioma cells through Cell Counting Kit-8 assays, flow cytometry, western blotting, and transmission electron microscopy. Western blot was used to explore how SLC3A2 affects glioma sensitivity to ferroptosis through the AKT/NF-E2-related factor 2 (NRF2)/glutathione peroxidase 4 (GPX4) axis. By establishing a subcutaneous xenograft tumor model in BALB/c-nude mice, we investigated the growth of tumors following the knockout of SLC3A2 in glioma cells. Results: Downregulation of SLC3A2 suppressed the malignant phenotype of glioma by blocking the cell cycle and epithelial-mesenchymal transition processes. On the other hand, loss of SLC3A2 not only downregulated SLC7A11 but also prevented the activation of the AKT/NRF2/GPX4 axis. These lead to increased accumulation of reactive oxygen species and lipid peroxides, ultimately enhancing the susceptibility of glioma to ferroptosis. Conclusion Our findings suggest that SLC3A2 is an oncogene in gliomas, promoting their occurrence and development. It plays a critical role in ferroptosis resistance through the AKT/NRF2/GPX4 axis.

The lung is a vital organ that is in direct contact with the external environment.It is extremely susceptible to a variety of exogenous factors,which can trigger a series of inflammatory responses and lead to varying degrees of tissue damage.With the development of genetic engineering technology,silencing specific target genes through RNA interference has become a new strategy for the treatment of lung injury.Small interfering RNA(siRNA)is a crucial role in RNA interference that can bind to the target gene through base complementary pairing to inhibit its expression,thereby producing a corresponding regulatory effect.Due to its specific targeting and low biological toxicity,siRNA is gradually becoming an ideal tool for the treatment of lung injury and other lung diseases.This article reviews the mechanism of action of siRNA and its application progress and research status in the treatment of lung injury.

Objective To explore the application effect of constructing a data sharing-based multidrug-resistant or-ganism(MDRO)information reminder system combined with multidisciplinary standardized measures on the whole-process closed-loop management of MDRO.Methods Hospitalized patients from whom MDRO were detected from January 1 to July 31,2024 were taken as the control group,those from August 1,2024,to May 31,2025 were as the intervention group.The control group adopted the traditional manual reporting mode for MDRO,while the in-tervention group adopted the combination of MDRO reminder system and multidisciplinary management mode.Differences in isolation order issuing rate for MDRO and process-and outcome-indicators for multidisciplinary spe-cialty before and after system implementation were compared.Results After implementing information reminder system combined with multidisciplinary measures,issuing rates of ≤24 hour and＜4 hour MDRO isolation orders in the intervention group were both higher than in the control group([90.20％vs 65.23％,P＜0.05],[80.64％vs 55.08％,P＜0.001],respectively).Antimicrobial use rate in the intervention group was lower than in the con-trol group(36.27％vs 43.41％),with a statistically significant difference(P＜0.05).The implementation rates of MDRO prevention and control measures,pathogen detection rates,and fluorescence labeling clearance rates in the intervention group were all higher than those in the control group,all with statistically significant differences(all P＜0.05).The detection rate of MDRO decreased compared with the control group(10.83％vs 16.49％),and the in-cidence of MDRO healthcare-associated infection in the intervention group was lower than that in the control group(0.09％vs 0.19％),both with statistically significant differences(both P＜0.001).The treatment expense in the intervention group reduced by 27 422 Yuan compared with the control group.Conclusion This study constructed an MDRO reminder system,realized full-chain monitoring system for the multidisciplinary MDRO information interac-tion platform,strengthened multidisciplinary in-depth integration,and improved the prevention and control effect for MDRO.
