To interpret the evidence-to-decision （EtD） framework and to illustrate its application in traditional Chinese medicine （TCM） guideline development using the example of the Pharmacovigilance Guideline of Chinese Patent Medicine， thereby providing methodological references for TCM guideline standardization. Based on the core three stages of the EtD framework （formulating the question， making an assessment of the evidence， and drawing conclusions）， critical decision points and evaluation evidence within the evidence-translation process were systematically addressed， aligning with the purpose， scope， and key questions of the guideline. Qualitative research methods， such as the nominal group technique， were employed to formulate recommendations. The analysis was conducted based on the EtD framework. During question formulation， the specific characteristics and practical needs of pharmacovigilance for Chinese patent medicines were clarified， focusing on the core objective of safety assurance throughout the product lifecycle. In the evidence assessment， multi-source evidence was integrated， including policy documents， literature research， and expert consensus， completing the evidence evaluation. Finally， in recommendation-forming， dispersed research evidence and expert experience were synthesized into consensus， culminating in the guideline's completion through solicitation of opinions and peer review. The EtD framework provides a structured tool for evidence-to-decision translation in TCM guideline development， effectively enhancing the transparency and scientific rigor of the process. Therefore， it is recommended that TCM guideline development adopt the EtD framework to improve the evidence-to-decision process with TCM characteristics.

AIM: To investigate the diagnostic and prognostic value of differential expression of Cyclin D1 and p53 in eyelid tumors.METHODS: This retrospective study enrolled patients who underwent surgical resection for eyelid tumors at our hospital between March 2018 and March 2023. Participants were categorized into benign and malignant groups based on tumor characteristics. Clinical data were collected. Genetic data for eyelid tumors were obtained from the GEO database, and differential gene analysis, including volcano plot visualization and KEGG pathway enrichment analysis, was performed using the Sangerbox 3.0 platform. Immunohistochemistry was used to detect the expression levels of Cyclin D1, p53, and BAX in tissue samples. Correlations with clinical features were analyzed using Spearman analysis, and prognostic factors were identified via Logistic regression analysis.RESULTS: This study included 69 patients with eyelid tumors(78 eyes), categorized into a benign group(37 patients, 41 eyes)and a malignant group(32 patients, 37 eyes)based on tumor characteristics. There were significant differences between the two groups in histological subtype, TNM staging, vascular invasion, differentiation status, and local infiltration(all P<0.05). Among benign tumors: pigmented nevi in 11 eyes(27%), hemangiomas in 9 eyes(22%), squamous cell papillomas in 5 eyes(12%), epidermoid cysts in 5 eyes(12%), seborrheic keratoses in 4 eyes(10%), neurofibromas in 3 eyes(7%), and both calcifying epithelioma and xanthelasma in 2 eyes each(5%); among malignant tumors: basal cell carcinoma in 18 eyes(49%), meibomian gland carcinoma in 8 eyes(22%), squamous cell carcinoma in 5 eyes(14%), sebaceous gland carcinoma in 4 eyes(11%), lymphoma and malignant melanoma each in 1 eye(3%). At the follow-up cutoff date of March 2025, the 2-year survival rate in the benign group(95%)was significantly higher than that in the malignant group(78%; P<0.05). Bioinformatics analysis identified 4 103 differentially expressed genes, including Cyclin D1, p53, and BAX, which were predominantly involved in pathways such as the p53 signaling pathway and calcium-related signaling. Spearman analysis revealed that local invasion(rs=0.71, P<0.05)and TNM stage(rs=0.73, P<0.05)correlated with Cyclin D1 expression; local invasion(rs=0.76, P<0.05)and histological subtype(rs=0.65, P<0.05)correlated with p53 expression. Logistic regression results indicated that Cyclin D1, p53, TNM staging, and local invasion were prognostic risk factors. ROC curve analysis demonstrated that the combined detection of these four indicators had the highest predictive value for prognosis(AUC=0.83).CONCLUSION: High expression of cyclin D1 and p53 serves as molecular markers for distinguishing benign from malignant eyelid tumors and assessing prognosis. Combined detection of these markers with TNM staging and local invasion demonstrates high predictive value for prognosis.

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 establish ferroptosis-related risk characteristics, to evaluate the prognostic correlation of ferroptosis-related genes in hepatocellular carcinoma, and to explore the complex relationship between hepatocellular carcinoma, ferroptosis and immune microenvironment.Methods:The bioinformatics analysis involved obtaining ferroptosis-related differentially expressed genes (DEGs) from the GeneCards database and the cancer genome atlas database. The biological functions of ferroptosis-related DEGs were analyzed using gene ontology and Kyoto encyclopedia of genes and genomes pathway enrichment. Ferroptosis-related DEGs clusters were identified using univariate Cox regression analysis and cluster analysis, etc. The correlation between ferroptosis-related DEGs clusters and tumor immune microenvironment and tumor occurrence score was evaluated using immunopanoramic analysis and tumor-related score analysis. Based on ferroptosis-related characteristics, a ferroptosis-related characteristic spectrum and nomogram were constructed using multivariate Cox regression and correlation analysis, etc. The correlation between the risk characteristics and tumor immune microenvironment, tumor occurrence score and gene mutation were evaluated using immune panoramic analysis, tumor-related score analysis and gene mutation analysis. In the experimental verification stage, the mRNA expression levels of aurora kinase A ( Aurka), acetyl-CoA carboxylase alpha ( Acaca) and arrestin domain containing 3 ( Arrdc3) in mouse primary hepatocytes and mouse hepatoma Hepa1-6 cells were verified by real-time reverse transcription-PCR (RT-qPCR). The mRNA expression levels of AURKA, ACACA and ARRDC3 in adjacent normal tissues and tumor tissues of patients with hepatocellular carcinoma were verified by RT-qPCR. A heat map was used to show the correlation between clustering and clinical parameters, and this was analyzed using a chi-square test. Significance analysis was performed using a two-sided unpaired t test. Results:A total of 35 up-regulated genes and 19 down-regulated genes were identified. These genes were mainly involved in biological processes and signaling pathways related to ferroptosis, oxidative stress and fatty acid metabolism. A total of 14 ferroptosis-related DEGs were identified to be associated with prognosis. The clusterring effect was best when hepatocellular carcinoma patients were divided into two subgroups. The survival rate of cluster 2 was lower than that of cluster 1 ( P<0.05). There was no significant difference in the tumor immune dysfunction and exclusion (TIDE) score between cluster 2 and cluster 1 ( P=0.43). Cluster 1 exhibited higher levels of immune cell infiltration, particularly CD4 + T cells ( P<0.01). The expression levels of 10 major histocompatibility complex (MHC) molecule-related genes were higher in cluster 1. The angiogenesis activity score ( P=0.048) and stemness score ( P=0.038) of cluster 2 were increased, and the expression levels of programmed death-1 ( PDCD1) and cytotoxic T lymphocyte-associated antigen-4 ( CTLA-4) in cluster 2 (5.924±0.013 and 5.475±0.042) were higher than those in cluster 1 (4.539±0.143 and 4.372±0.176) (both P<0.05). The expression levels of AURKA, glucose-6-phosphate dehydrogenease ( G6PD), ACACA, GABA type A receptor associated protein like 1 ( GABARAPL1) and ARRDC3 were correlated with the T stage, clinical stage and survival status of hepatocellular carcinoma. The survival rate of the high-risk group was lower than that of the low-risk group with time ( P<0.01). The area under the curve of the risk characteristics at 1, 3 and 5 years was 0.797, 0.717 and 0.639, respectively. The actual survival time 1, 3, and 5 years was highly consistent with the corresponding predicted survival time. The levels of memory B cell infiltration, angiogenesis activity score and cell stemness score, programmed death-ligand 1, CTLA-4, hepatitis A virus cell receptor 2, lymphocyte activation gene 3 and PDCD1 gene expression (0.013 8±0.036 0, 0.884±0.212, 0.387±0.135, 6.273±0.228, 5.847±0.331, 8.179±0.259, 6.859±0.263 and 5.142±0.326) in the high-risk group were higher than those in the low-risk group (0.001 5±0.021 0, 0.874±0.132, 0.298±0.125, 5.866±0.132, 3.742±0.237, 7.236±0.321, 6.324±0.242 and 4.513±0.211) ( P<0.05, 0.01). The expression levels of MHC molecule-related genes in the high-risk group were also higher than those in the low-risk group ( P<0.05, 0.01), while the infiltration levels of resting mast cells, activated natural killer cells, and resting natural killer cells (0.043 2±0.135 0, 0.032 1±0.143 0 and 0.016 3±0.001 9) and the TIDE score (0.072 0±0.018 0) in the high-risk group were lower than those in the low-risk group (0.054 9±0.023 0, 0.042 7±0.017 0, 0.024 6±0.021 2 and 0.094 0±0.013 5) ( P<0.05, 0.01). The top five genes with the highest mutation frequency in the high-risk group were tumor protein P53 ( TP53, 43%), titin ( TTN, 21%), catenin beta 1 ( CTNNB1, 20%), mucin 16 ( MUC16, 18%) and piccolo presynaptic cytomatrix protein ( PCLO, 11%). The top five genes with the highest mutation frequency in the low-risk group were CTNNB1 (30%), TTN (24%), albumin ( ALB, 16%), MUC16 (15%) and PCLO (11%). The cube protein and PCLO showed the co-occurrence of gene mutations in the high-risk group, while MUC16 and axis 1 protein showed the co-occurrence of gene mutations in the low-risk group. There was no significant difference in tumor mutation burden (TMB) between the high-risk group (1.374±0.026) and the low-risk group (1.303±0.081) ( P=0.073). There was no significant difference in survival time between the high-TMB group (2.3 years) and the low-TMB group (3.8 years) ( P=0.293). The mutation rates of AURKA, G6PD, ACACA, GABARAPL1 and ARRDC3 genes (2.0%, 2.0%, 4.0%, 0.3% and 0.6%) were relatively low. The relative expression levels of Aurka, Acaca and Arrdc3 mRNA in Hepa1-6 cells (13.331±0.000, 6.619±0.000 and 1.209±0.002) were higher than those in mouse primary hepatocytes (1.000±0.000, 1.000±0.000 and 1.000±0.000) (all P<0.01). The relative expression levels of AURKA, ACACA and ARRDC3 mRNA in tumor tissues of patients with hepatocellular carcinoma (2.102±0.365, 2.476±0.351 and 11.460±9.189) were higher than those in adjacent normal tissues of patients with hepatocellular carcinoma (1.122±0.648, 0.831±0.935 and 0.852±0.171) ( P<0.05, 0.01). Conclusions:This study constructed a prognostic signature comprising five ferroptosis-related genes ( AURKA, G6PD, ACACA, GABARAPL1, and ARRDC3) that is highly correlated with clinical hepatocellular carcinoma data. This study highlights the significance of ferroptosis-related genes as prognostic markers for hepatocellular carcinoma and provides insights into the complex relationship between hepatocellular carcinoma, ferroptosis, and the immune microenvironment.

Objective To evaluate the impact of different CO2 fractional laser parameters on the formation of micro-scopic treatment zone(MTZ)on the nail surface and to compare the observations of these areas using various in-struments.Methods This study applied 60 different combinations of CO2 fractional laser parameters,including pulse widths ranging from 100-1 000 μs and powers from 10-60 W,on bovine hoof samples.The formation and overall changes of MTZ on the nail surface were subsequently observed and compared using optical microscopy,in-verted microscopy,and white light interferometry.The relationships between MTZ and various laser parameters were analyzed.Results Significant statistical differences were observed between white light interferometry and inverted microscopy in MTZ assessment(P＜0.001).White light interferometry demonstrated greater accuracy and reliability in measuring micro-ablative column(MAC)and thermal coagulation zone(TCZ).There were also significant statis-tical differences in MAC formation based on CO2 fractional laser parameters(P＜0.001),with the strongest correla-tion found between pulse width and MTZ(0.656 68-0.772 62).Longer pulse widths correlated with larger MAC areas and depths,as well as increased TCZ thickness.Conclusions White light interferometry shows significant advantages in assessing the impact of CO2 fractional laser ablation on tissue depth.These findings provide valuable insights for optimizing laser parameters in the treatment of nail disorders and contribute to enhancing the safety and efficacy of such therapies.

Objective:To explore the effect of loneliness on self-perceived aging among elderly patients after gastric cancer surgery, and to examine the mediating role of emotion regulation strategies, in order to provide a basis for clinical interventions.Methods:A convenience sample of 220 elderly postoperative gastric cancer patients hospitalized in Shanxi Provincial Cancer Hospital between August and November 2024 was selected. Data were collected using a general demographic questionnaire, the Emotion Regulation Questionnaire (ERQ), the Cancer Loneliness Scale (CLS), and the Brief Aging Perceptions Questionnaire (B-APQ). A structural equation model was constructed using AMOS 26.0, and the significance of the mediating effect was tested using the bootstrap method with 5 000 resamples.Results:A total of 220 questionnaires were distributed in this study, and 203 valid questionnaires were recovered, with a response rate of 92.27%. The total B-APQ score was (47.45±11.43). For the ERQ, the score for cognitive reappraisal was (22.80±8.17), and for expressive suppression was (18.37±5.10). The CLS score was (18.19±6.11). Mediation analysis showed that loneliness had a direct effect of 0.353 on self-perceived aging. Emotion regulation strategy—cognitive reappraisal—partially mediated the relationship between loneliness and self-perceived aging, with a mediation effect value of 0.178, accounting for 33.52% of the total effect (0.178/0.531) .Conclusions:Clinical practitioners should implement interventions to reduce loneliness in elderly patients after gastric cancer surgery and guide them in adopting cognitive reappraisal as an emotion regulation strategy. These approaches may help promote positive aging in this patient population.

Objective:To combine the conventional audiometric curves and extended high frequency audiometric curves of patients with sensorineural deafness to form a full-frequency audiometric curve and to perform typing, so as to comprehensively understand the hearing status of patients with sensorineural deafness.Methods:This study was a cross-sectional study. The study subjects included 249 patients with sensorineural hearing loss who visited the Otolaryngology-Head and Neck Surgery outpatient clinic of the PLA General Hospital between July 2019 and December 2020. Among them, 146 were male and 103 were female, aged 11 to 80 years. The cases included 123 with mild hearing loss, 70 with moderate hearing loss, 32 with moderately severe hearing loss, 17 with severe hearing loss, 6 with profound hearing loss, and 1 with total deafness. According to the national standard GB/T16403-1996, conventional pure-tone audiometry (125-8 000 Hz) was performed on the 249 patients with sensorineural hearing loss to obtain their conventional-frequency hearing curves, which were then classified. Extended high-frequency pure-tone threshold testing (9 000-20 000 Hz) was conducted using extended high-frequency headphones, specifically including eight frequencies: 9 000, 10 000, 11 200, 12 500, 14 000, 16 000, 18 000, and 20 000 Hz. Ultimately, the full-frequency hearing curves (125-20 000 Hz) of each patient were obtained. The K-means clustering analysis method was used to classify the hearing curves based on their characteristics, and the results of the K-means clustering analysis were partially adjusted through manual screening.Results:The conventional hearing curves of all 249 patients were consistent with sensorineural hearing loss. The detection rates for extended high frequencies (9 000, 10 000, 11 200, 12 500, 14 000, 16 000, 18 000, and 20 000 Hz) were 96.79% (241/249), 94.38% (235/249), 87.95% (219/249), 78.31% (195/249), 65.46% (163/249), 22.09% (55/249), 10.84% (27/249), and 0.80% (2/249), respectively. The conventional-frequency hearing curves of the patients could be classified into the following types: low-frequency descending type (50/249, 20.08%), conventional-frequency steep descending type (78/249, 31.33%), conventional-frequency gradual descending type (58/249, 23.29%), conventional-frequency flat type (25/249, 10.04%), conventional-frequency 4 000 Hz notch type (30/249, 12.05%), and other types (8/249, 3.21%). By incorporating extended high-frequency hearing data, the full-frequency hearing curves of 235 patients were further classified into the following types based on different characteristics: full-frequency hill type (32/235, 13.62%), full-frequency ascending type (28/235, 11.91%), full-frequency 8 000 Hz notch type (14/235, 5.96%), full-frequency steep descending type (82/235, 34.89%), full-frequency gradual descending type (34/235, 14.47%), full-frequency shoulder-raising type (7/235, 2.98%), full-frequency shoulder-dropping type (25/235, 10.64%), full-frequency flat type (8/235, 3.40%), and other full-frequency types (5/235, 2.13%).Conclusions:Compared to the classification based on conventional-frequency hearing curves, the full-frequency hearing curves of patients with sensorineural hearing loss provide a more comprehensive representation of their overall hearing status. Patients with the same conventional-frequency hearing curve classification may exhibit different full-frequency hearing curve types, suggesting potential differences in the location and extent of pathological damage within their auditory systems.

Objective:To investigate the clinical characteristics and prognostic significance of germline mutations in patients with myelodysplastic neoplasms (MDS) .Methods:Clinical data from 407 patients with MDS [male, 252; female, 155; median age, 64 (range, 19-85) years] diagnosed at the First Affiliated Hospital of Zhejiang University School of Medicine were retrospectively analyzed. The clinical features and prognostic effects of germline mutations were evaluated.Results:The prevalence of germline mutations in patients with MDS was 5.9% (24/407), peaking at 20.0% in the group aged 21-30 years. The spectrum of germline mutations comprised DDX41 (9 cases, 2.2%), TP53 (3 cases, 0.7%), and single cases of RUNX1, TET2, MPL, CBL, ATRX, CEBPA, ETV6, IDH1, KDM5C, SBDS, GNAS, and CTC1. Patients with germline mutations exhibited significantly lower peripheral WBC counts than those without (1.87×10 9/L vs 2.50×10 9/L, P=0.018), but showed comparable median overall survival (21.3 months vs 21.1 months, P=0.97). Patients with DDX41 germline mutations, compared with those with other germline mutations, had a significantly older median age (65 vs 54 years, P=0.010), lower WBC counts (1.51×10 9/L vs 2.31×10 9/L, P=0.040), increased mean corpuscular volume (111.80 fl vs 97.25 fl, P=0.003), and a higher prevalence of normal karyotypes (100.0% vs 53.3%, P=0.022). The most frequently co-occurring somatic mutations in DDX41 germline mutation carriers were ASXL1, TET2, and RUNX1. Conclusion:In this study, the detection rate of germline mutations in MDS patients was 5.9% (24/407), peaking at 20% in the group aged 21-30 years. DDX41 and TP53 were the most prevalent germline mutations. DDX41 mutation carriers displayed distinct clinical characteristics; however, germline mutations overall showed no significant prognostic effect.

Objective:To identify the relevant factors for the first-course remission of acute myeloid leukemia (AML) and to develop a predictive model as well as assess its predictive capability.Methods:Clinical data of 749 patients newly diagnosed with AML admitted to the Department of Hematology, the First Affiliated Hospital, Zhejiang University, School of Medicine from January 1, 2019, to April 30, 2023, were collected and randomly divided into training and validation sets. Multivariate logistic regression analysis was conducted to determine variables associated with complete remission in the first course of induction therapy, and a predictive model was established based on these variables. The receiver operating characteristic (ROC) curve of the predictive model was plotted, and the area under the curve (AUC) was calculated.Results:The indicators predicting the first remission course included peripheral blood white blood cell count during onset, CBF::MYH11 fusion gene, CEBPA bZIP region mutation, myelodysplastic syndrome-related gene mutation, and induction chemotherapy regimen selection as independent factors for the first remission course. The model’s area under the training and validation curves was 0.738 (95% CI: 0.696-0.780) and 0.726 (95% CI: 0.650-0.801), respectively. The Hosmer-Lemeshow test results yielded P-values of 0.993 and 0.335, respectively. Conclusion:In this study, the developed model demonstrates a strong predictive capability for the efficacy of the first course of patients with AML, providing valuable guidance to clinicians in assessing patient prognosis and selecting appropriate treatment strategies.
