Atherosclerosis (AS) remains the core pathological basis underlying the high incidence and high rates of mortality and disability associated with cardiovascular disease (CVD) worldwide. Its essence is not merely lipid deposition, but rather an immune-mediated disease of the vascular wall characterized by an interplay of lipid metabolism disorders and chronic inflammation, with damage to vascular endothelial cells serving as the initiating event. As the disease progresses, it involves complex synergistic interactions among various cellular components, including endothelial cells, macrophages, and inflammatory cells, ultimately leading to plaque formation, instability, and even fatal thrombotic events. In recent years, the central driving role of lipid metabolic reprogramming in the progression of AS has garnered increasing attention from the scientific community. Among the vast array of lipid molecules, long-chain fatty acids (LCFAs) have become a primary focus of research due to their exceptional physiological functions. Traditional views have primarily emphasized the basic physiological functions of LCFAs: serving as highly efficient energy substrates through mitochondrial β-oxidation and acting as key structural components of cellular phospholipid membranes. However, emerging evidence clearly indicates that the functions of LCFAs extend far beyond those of mere metabolic fuel. They also act as potent bioactive signaling molecules, playing an indispensable multidimensional role in the pathogenesis of AS. Equally noteworthy and representing a paradigm shift in cardiovascular research is the emerging theory of the “gut-heart axis”. This theoretical framework views the human gut microbiota—comprising trillions of microorganisms—as a critical and metabolically active “bioreactor”. A wealth of clinical and multi-cohort epidemiological studies have conclusively demonstrated that imbalances in the composition and function of the gut microbiota are highly correlated with the clinical risk and severity of AS. Within this axis, the gut microbiota serves as the primary processing hub for dietary lipids. It actively participates in the digestion and biochemical remodeling of LCFAs, thereby altering their saturation and chemical structure and generating a wide variety of gut microbial metabolites. The effects of these gut-derived lipid metabolites extend far beyond the local intestinal microenvironment. Upon entering the bloodstream, these circulating microbiota metabolites act as endocrine signals. Given the extreme complexity of the underlying mechanisms, a comprehensive elucidation of the synergistic and bidirectional interactions between LCFAs and the gut microbiota in vascular pathology is particularly urgent. Therefore, this article aims to provide a systematic review of the multidimensional regulatory mechanisms of LCFAs and their associated gut microbiota metabolites in the onset, progression, and clinical manifestations of AS. By thoroughly exploring the interaction patterns within the “LCFAs-gut microbiota-AS” triad, this review seeks to fundamentally expand our understanding of the pathogenesis of CVDs. More importantly, translating these mechanistic insights into clinical practice holds tremendous promise. We hope to provide a solid theoretical foundation for the future development of novel AS prevention and treatment strategies based on non-traditional approaches. These include precision nutritional interventions (i.e., dietary lipid intake plans tailored to an individual’s unique microbiome profile) and targeted microbiome modulation therapies (such as next-generation probiotics, prebiotics, or specific metabolite supplements). Targeting the gut as a “reactor” to treat vascular wall lesions represents a promising direction for future cardiovascular medicine.

OBJECTIVE To develop a pharmacist-led intervention model for reducing drug-related medical insurance claim denial risks， so as to provide practical references for healthcare institutions in fulfilling their primary responsibility for medical insurance fund supervision. METHODS A risk matrix method was employed by the pharmacists to assess the risks associated with drug‑related medical insurance claim rejections in our hospital during 2024. Intervention measures were developed targeting high‑risk factors (including inappropriate indications for medical insurance coverage, exceeding the covered treatment course, and inappropriateness of gender and age) from three dimensions, namely organizational structure, technical prevention and control, and closed‑loop management. Changes in drug‑related claim rejection data were compared between 2024 (pre‑intervention) and 2025 (post‑intervention), and the interception effect of the pre‑prescription review system was evaluated after the intervention. RESULTS After the intervention, the total amount of drug‑related medical insurance claim rejections in our hospital was reduced by 57.24% compared with that before the intervention, and the number of rejected items decreased from 10 108 to 2 892. Specifically, the number of rejected items due to inappropriate indications, exceeded treatment course, inappropriate gender, and inappropriate age was reduced by 70.94%, 74.26%, 83.86%, and 96.70%, respectively. Throughout the year following the intervention, a total of 5.605 yuan million in outpatient prescription drug amounts and 4.683 million yuan in inpatient medication order amounts that did not meet the insurance‑limited payment requirements were intercepted by the pre‑prescription review system. The proportion of drug‑related claim rejection amount to the total medical service claim rejection amount of our hospital decreased to 19.7%. CONCLUSIONS The pharmacist-led multi-department collaborative， technical prevention and control， and dynamic optimization integrated full-process intervention model is highly operable and has significant practical effects. It has important promotion value in reducing drug-related medical insurance claim denial risks.

The mental health management of laboratory animals is a critical factor in ensuring the reliability of scientific research data. However, due to the subtle nature of mental state alterations and the limitations of current assessment methods, the mental health of laboratory animals is often overlooked by researchers. Therefore, there is an urgent need to explore a new, objective, simple, and practical method for evaluating mental health. Stress, as a primary factor inducing alterations in the mental state of animals, can influence experimental results across multiple research fields through the neuroendocrine-immune network. This paper first elucidates the necessity of mental health management in laboratory animals from three perspectives: factors contributing to stress, neural mechanisms of stress, and research areas affected by stress. It highlights that excluding animals with abnormal mental states before experiments can enhance the efficiency and reproducibility of biomedical studies. Second, this paper briefly summarizes existing methods for assessing the health of laboratory animals, pointing out that approaches such as behavioral tests and metabolomics have many limitations in evaluating stress responses. Existing methods struggle to meet the demand for simple, objective, and non-invasive assessment methods in animal management. Therefore, this paper focuses on hair, a biological sample with the advantages of cumulative information and non-invasive collection, and systematically describes the theoretical basis and technological advances in using hair characteristics as indicators of stress responses from three perspectives: hair traits, the levels of substances in hair, and artificial intelligence (AI). It proposes and supports an innovative technical pathway that combines hair traits with AI-based image analysis, with the aim of offering an improved solution for non-invasive and objective stress assessment, while providing theoretical support for improving the health management system of laboratory animals.

Objective Jejunal interposition is an important option for restoring gastrointestinal continuity in patients with complex esophageal cancer in whom the stomach is unavailable for reconstruction due to previous gastrectomy, tumor involvement, failed gastric conduit, or other constraints. Although the jejunum offers a caliber similar to the esophagus, a rich blood supply, and preserved peristaltic function, anatomical variations in mesenteric length and vascular arcades render long-segment and high-level reconstruction susceptible to excessive tension, mesenteric torsion, venous congestion, and inadequate distal perfusion. This consensus aims to provide standardized recommendations for the application of jejunal interposition in this specific patient population. Methods This consensus was developed in accordance with the WHO Handbook for Guideline Development and Chinese national guideline development standards, with reference to the Appraisal of Guidelines for Research & Evaluation Ⅱ(AGREE Ⅱ), Reporting Items for Practice Guidelines in Healthcare (RIGHT), and Scientific, Transparent and Applicable Rankings (STAR) checklists. The project was registered on the international practice guidelines registry platform (PREPARE-2026CN1384). The working group systematically searched Chinese and English evidence addressing 12 clinical questions. Evidence was graded using the Oxford Centre for Evidence-Based Medicine (OCEBM) 2009 system, with structured appraisal of risk of bias, inconsistency, indirectness, and imprecision. Recommendations were formulated through two rounds of Delphi surveys and a face-to-face consensus meeting, with an agreement threshold of ≥75%. Results The consensus generated 12 recommendations covering indications, selection between jejunum and colon, preoperative assessment, surgical approach and reconstruction route, pedicled jejunal interposition (PJI), supercharged pedicled jejunal interposition (SPJ), indocyanine green (ICG) perfusion assessment, perioperative nutrition, management of anastomotic leakage, long-term follow-up, and special treatment scenarios. Given that the available direct evidence is predominantly derived from single-center retrospective cohorts and case series, recommendations extrapolated from general esophagectomy or other gastrointestinal surgical evidence are deliberately phrased with caution. Conclusion Jejunal interposition is a safe and effective approach for digestive tract reconstruction in patients with complex esophageal cancer in whom the stomach is unavailable. This consensus emphasizes that clinical decision-making should be individualized based on the patient's prior treatment history, reconstruction height, vascular anatomy, technical availability, and institutional experience in the Chinese context.

Objective:To assess the safety and efficacy of thiotepa, busulfan, and etoposide (TBE) conditioning followed by autologous hematopoietic stem-cell transplantation (TBE auto-HSCT) in primary central nervous system lymphoma (PCNSL) patients.Methods:Clinical data from 27 PCNSL patients who received TBE auto-HSCT at the Fifth Medical Center of PLA General Hospital between November 1, 2021, and April 30, 2024, were retrospectively analyzed.Results:Twenty-seven patients [16 males, 11 females; median age 57 (23–72) years] were included, with 12 (44.4%, 12/27) over 60. Twenty-five had newly diagnosed PCNSL and 2 were relapsed. Median time from diagnosis to transplantation was 6.9 (5.0–10.0) months. TBE auto-HSCT increased complete remission (CR) rate from 63.0 to 96.3% ( P= 0.005), and 9 of 10 patients in partial remission achieving CR post-transplant. Median follow-up was 24.5 months (range 2.0–36.0). Two-year progress-free and OS rates were (87.2±6.9) % and (88.6±6.2) %, respectively. Common grade 3 nonhematologic adverse events were diarrhea (18.5%, 5/27) and bacterial infections (14.8%, 4/27). One patient (64 years old) died from carbapenem-resistant Enterobacteriaceae infection within 2 months post-transplant, yielding a 100-day treatment-related mortality of 3.7% (1/27) . Conclusion:TBE-conditioned high-dose chemotherapy with auto-HSCT is effective, safe, and well-tolerated in PCNSL patients, including the elderly.

Objective To explore the different potential subtypes of psychosocial adaptation among young and middle-aged stroke patients,and analyze the relationship between different potential subtypes and quality of life,so as to provide references for the subsequent development of targeted interventions.Methods A total of 406 young and middle-aged stroke patients in 4 tertiary hospitals in Suzhou from June 2023 to June 2024 were recruited by convenience sampling.The General Information Questionnaire,the Self-Report Psychosocial Adjustment to Illness Scale and the EuroQol five-dimensional questionnaire were conducted for investigation.Latent profile analysis was used to explore the potential subtypes of psychosocial adaptation among young and middle-aged stroke patients.Generalized linear regression analysis was conducted with quality of life as dependent variables.Results A total of 380 young and middle-aged stroke patients were included.The psychosocial adaptation of patients could be classified into 3 potential subtypes:high adaptation level type(23.90％),medium adaptation level with health concerns type(46.40％),and low adaptation level with psychological barriers type(29.70％).The results of generalized linear regression analysis showed that potential subtypes of psychosocial adaptation were the influencing factors for quality of life in young and middle-aged stroke patients(P＜0.05).Conclusion There was group heterogeneity in psychosocial adaptation among young and middle-aged stroke patients,and the potential subtype of psychosocial adaption was an important factor affecting the quality of life of patients.It is suggested that medical staff should focus on patients with low adaptation level with psychological barriers type,and take targeted interventions according to characteristics of different subtypes of patients,so as to improve their quality of life.

Objective:To develop and validate clinical predictive models for identifying poor short-term response to recombinant human growth hormone(rhGH) treatment in children with short stature.Methods:A retrospective analysis was conducted on 118 children diagnosed with growth hormone deficiency or idiopathic short stature who were treated at the First Affiliated Hospital of Zhengzhou University and two other hospitals between January 1, 2020, and January 1, 2024. A poor response to rhGH was defined as a height increase of less than 0.2 standard deviation score(SDS) after 6 months of rhGH treatment. LASSO regression was used to identify predictive variables from baseline and follow-up data. Two logistic regression models were conducted: Model A(incorporating baseline variables only) and model B(incorporating both baseline and follow-up variables), and nomograms were created for visualization. External data and internal resampling were used for dual validation of the models, and their performance was compared.Results:A total of 118 children with short stature were included. Six baseline predictive variables(diagnosis, initial height SDS, bone age, bone age-chronological age difference, rhGH dose, and gender) and one follow-up variable(height SDS after 3 months of rhGH treatment) were identified. Area under the curve values for Model A and Model B were 0.753(95% CI 0.696-0.811) and 0.930(95% CI 0.891-0.975), respectively. Calibration curves, decision curve analysis, and other evaluation metrics demonstrated good discrimination and clinical utility for both models. Model B, incorporating the 3-month follow-up variable, showed superior predictive performance compared to Model A. Conclusions:The clinical prediction models developed in this study(Model A and Model B) are practical and reliable tools for quantitatively, conveniently, and intuitively identifying children with short stature at risk of poor response to rhGH treatment.

Objective To discuss the application of partial antiplatelet drug genotype detection and thromboelastography-platelet mapping(TEG-PM)in guiding the selection of antiplatelet regimens in patients with intracranial aneurysms(IAs)after receiving stenting.Methods A total of 106 patients with IAs in the First Affiliated Hospital of Kunming Medical University,who underwent implantation of stent and received the testings of platelet-endothelial aggregation receptor 1(PEAR 1)and clopidogrel-related gene-cytochrome P450 enzyme 2C19(CYP2C19),and some of whom received TEG-PM testing from January 2019 to August 2022,were collected for this study.The patients were divided into group A(gene detection group,according to the drug-related gene detection results to adjust the medication)and group B(combination group,according to the two testing results to guide the medication).The patient's gender,age,testing data were collected,and the occlusion of IAs,stent intimal hyperplasia,drug-related hemorrhagic and ischemic complications during follow-up period were recorded.Results A total of 123 IAs lesions in 106 patients were treated.The patient's mean age was(53.67±6.66)years,67 patients were female.Group A had 41 patients and group B had 65 patients.No statistically significant differences in the baseline data,IAs features,stent types used,and medication regimen existed between the two groups(all P＞0.05).In Group A,the ischemic complications and hemorrhagic complications occurred in two patients each.In Group B,no ischemic complications occurred and 4 patients developed hemorrhagic complications.The difference in the incidence of related complications between the two groups was not statistically significant(P=0.287 and P=0.782 respectively).There were no statistically significant differences in the postoperative one-month and 3-month intimal hyperplasia grade and the aneurysm occlusion rate between the two groups(all P＞0.05).The postoperative 6-month overall intimal hyperplasia grade in Group A was slightly higher than that in Group B,and the difference was statistically significant(P=0.034).Conclusion In order to improve the precision and individualized treatment of antiplatelet therapy,it is suggested that clinicians should adopt TEG-PM-guided conventional double-antibody therapy first when making selection of testing items.For patients with insufficient inhibition rate indicated by TEG-PM,testing of the genes associated with antiplatelet drugs should be used.Based on the genetic test results it is necessary to determine the reasons for the insufficient inhibition rate as well as to adjust the medication promptly according to the specific situation of the patient,so as to ensure the effectiveness of antiplatelet therapy and achieve the purpose of individualized precision therapy.

OBJECTIVE To evaluate the efficacy and safety of Weiyan Tongluo Granules in treating chronic atrophic gastritis(CAG)and explore its potential mechanisms.METHODS From June 2020 to December 2022,100 CAG patients with spleen defi-ciency and blood stasis syndrome were enrolled and randomly divided into a trial group(n=50)and a control group(n=50)using a random number table.The trial group received Weiyan Tongluo Granules plus a folic acid placebo,while the control group received fo-lic acid tablets plus a traditional Chinese medicine granule placebo.The treatment course for both groups was 24 weeks,with 8 and 10 dropouts in the trial and control groups,respectively.Post-treatment comparisons included OLGA/OLGIM staging reversal rates,low-grade intraepithelial neoplasia regression rate,SSDPRO-CG(Patient-Reported Outcome Scale for Chronic Gastritis in Spleen-Stomach Diseases)scores,TCM syndrome scores,and safety indicators.Serum levels of PG I,PGⅡ,PGR,and G-17 were measured via ELISA before and after treatment.Gastric mucosal p-NF-κB and CDX2 protein expression levels were analyzed by Western blot,while mRNA levels of IL-1β,IL-6,VIL1,and MUC2 were quantified via qPCR.RESULTS After treatment,the trial group showed sig-nificantly higher OLGA and OLGIM stage reversal rates than the control group(P<0.05,P<0.01),though no significant difference was observed in low-grade intraepithelial neoplasia regression.Both groups exhibited significant improvements in physiological domain scores and total SSDPRO-CG scores(P<0.01),with the trial group outperforming the control group in physiological,independence,psychological domains,and total scores(P<0.05,P<0.01).TCM syndrome scores(total and sub-items:gastric distension,pain,poor appetite,bloating)decreased significantly in both groups(P<0.01),while the trial group showed greater reductions in loose stools and dull complexion(P<0.01).After-treatment,the trial group had significantly lower TCM syndrome scores than the control group(P<0.05,P<0.01).Serum PG I,PGⅡ,PGR,G-17,gastric mucosal p-NF-κB,CDX2,and IL-1β,IL-6,VIL1,MUC2 mRNA levels improved significantly in the trial group(P<0.05,P<0.01),while the control group improved only in PGⅡ(P<0.05,P<0.01).The trial group's improvements in these biomarkers surpassed the control group's(P<0.05,P<0.01).No treatment-related adverse events occurred in either group.CONCLUSION Weiyan Tongluo Granules ameliorate gastric mucosal pathology,clinical symptoms,psychological state,and quality of life in CAG patients without significant adverse effects.Its mechanism may involve sup-pressing the NF-κB pathway to reduce IL-1β and IL-6 expression,downregulating CDX2 to inhibit VIL1 and MUC2 transcription,thereby reversing the vicious cycle of inflammation-intestinal metaplasia.
