    Objective To construct a glycolysis-related gene model for predicting the prognosis of gastric cancer (GC) patients based on bioinformatics. Methods The messenger RNA expression profiles of GC patients were analyzed in The Cancer Genome Atlas program, and gene sets with significant differences between GC tissues and normal tissues were verified using gene set enrichment analysis. A glycolysis-related genes model for predicting the prognosis of GC patients was constructed using least absolute shrinkage and selection operator regression analysis, and the predictive performance of the model was validated using Kaplan-Meier survival analysis, receiver operating characteristic curve, and univariate and multivariate Cox regression analysis. Gene set variation analysis was performed to analyze the differences in biological pathway states between high-risk and low-risk groups. Results Fourteen glycolysis-related genes (PFKFB2、UHRF1、ACYP1、CLDN9、STC1、EFNA3、NUP50、ADH4、ANGPTL4、PKP2、VCAN、HIF 1A、LHX9、ANKZF1、ALDH3A2) were identified as prognostic markers for GC patients. Based on a risk score derived from these 15 gene features using Cox regression analysis, patients were classified into high-risk and low-risk groups. These 15 gene markers were independent biomarkers for predicting the prognosis, and patients with a low-risk score had a better prognosis. The combination of gene markers and clinical prognostic factors in a Nomogram effectively predicted overall survival and disease-free survival. Conclusion The established panel of 15 glycolysis-related gene markers can serve as reliable tools for predicting the prognosis of GC patients and may provide potential targets for glycolysis-targeted therapy in GC.

    Objective To evaluate the bioequivalence and safety of aspirin enteric-coated tablets in healthy Chinese adult. Methods A single-center, randomized, open, two-preparation, two-sequence, four-cycle, fully replicated design was used. The subjects took orally one tablet of test (T) or reference (R) preparation on fasting or fed condition every cycle. The plasma concentration of acetylsalicylic acid (ASA) was determined by liquid chromatography with tandem mass spectrometry (LC-MS/MS) method at different time points, and the bioequivalence and safety of the two formulations were evaluated. Results In the main results for pharmacokinetic parameters of T and R under fed condition, Cmax were (690.97±196.91) and (669.28±337.40) ng·ml-1, AUC0-t were (867.37±228.64) and (821.16±349.85) ng·h·ml-1, AUC0-∞ were (883.48±233.72) and (923.59±287.95) ng·h·ml-1, Tmax were (8.98±2.47) and (10.69±3.75) h. In the main result for pharmacokinetic parameters of T and R under fasting condition, Cmax were (466.83±222.89) and (441.42±211.99) ng·ml-1, AUC0-t were (753.24±269.49) and (678.50±278.85) ng·h·ml-1, AUC0-∞ were (809.11±309.27) and (726.51±267.00) ng·h·ml-1, Tmax were (5.81±2.53) and (6.41±2.47) h. The geometric mean ratios of the main pharmacokinetic parameters Cmax, AUC0-t and AUC0-∞ in the fed group were within the range of 80.00% to 125.00%, therefore the two formulations were bioequivalent. However,the fasting group did not meet the relevant criteria, and the two preparations were not equivalent. During the study period, 0 case and 2 cases of adverse events occurred under the fasting and the fed condition. No serious adverse events occurred. Conclusion The two kinds of aspirin enteric-coated tablets were bioequivalent in human under the fed condition, but not in the human under fasting conditions, and the formulations were safe and well tolerated.

    Objective To evaluate the clinical efficacy and safety of gemcitabine and oxaliplatin (GEMOX) combined with target-immunity therapy (lenvatinib and programmed cell death 1 [PD-1] monoclonal antibody) in patients with advanced biliary tract cancer (BTC). Methods Twenty-four patients with advanced BTC received GEMOX combined with target-immunity therapy visited Integrative Oncology Department or Hepatobiliary Surgery Department of our hospital from January 2015 to January 2024 were recruited. The primary end points were set as overall survival (OS) and progression-free survival (PFS), and the secondary end points were objective response rate (ORR), disease control rate (DCR) and safety. The safety and overall clinical efficacy of GEMOX combined with target-immunity therapy regimen on advanced BTC were comprehensively evaluated via tumor marker indexes (carcinoembryonic antigen [CEA], carbohydrate antigen 125 [CA125], CA199), adverse reactions rates, quality of life scores, imaging indicators, and other data. Results None of the 24 patients had complete remission (CR). ORR was 33.3% (8/24, 8 patients had PR), DCR was 66.7% (16/24; 8 patients had SD and 8 patients had PD, respectively), median OS was 13 months and median PFS was 8 months. After treatment, the levels of CA199 were significantly lower than those before treatment (P<0.05). The incidence of adverse events in 24 patients were rash (14/24, 58.3%), leucopenia (22/24, 91.6%), anemia (20/24, 83.3%). One patient had serious adverse events and withdrew from treatment, one patient died of biliary obstruction with infection during treatment. Conclusion GEMOX combined with target-immunity therapy regimen is safe and effective in the treatment of advanced BTC, it may be used clinically.

    Generative Artificial Intelligence (GAI) is emerged as a game-changing technology with far-reaching implications across various fields. It is expected to bring new opportunities for rapid development in numerous areas, including the education sector where GAI has already shown promising results through multi-platform integration. In the future, the iterative development of GAI will give rise to a plethora of potential applications in the field of medical humanities education, enhancing its effectiveness precisely, promoting its development, and creating innovative modes of panoramic experience in the teaching process. However, along with the inherent ethical issues of GAI technology, such as black box algorithms, information cocooning, data privacy and security, and discriminatory algorithms, there will also be risks with distinct medical humanities characteristics that arise from the deep integration of GAI and medical humanities education. For instance, there is a possibility of values being compromised, the diminishing of human dominance, and the imbalance of the binary relationship between teaching and learning due to an excessive reliance on GAI. In order to address these ethical concerns and devise effective countermeasures to mitigate the risks imposed by GAI in empowering medical humanities education, it is necessary to establish clear boundaries and maximize the potential of artificial intelligence. We must also ensure that GAI stays true to its original purpose in this era of rapid technological advancements, and create a conducive ecological environment for its development based on legal regulations.

    Objective To explore the clinical characteristics and diagnostic and therapeutic strategies of colonic telangiectasia. Methods A retrospective analysis was conducted on the clinical data of a patient with colonic telangiectasia who presented with repeated gastrointestinal bleeding and anemia, and relevant literature was reviewed. Results A 56-year-old female patient presented with recurrent black stools and alternating fresh bloody stools. Colonoscopy showed extensive network-like, dendritic, and spider nevus-like capillary dilation in multiple locations around the mucosa from the cecum to the descending colon, with the maximum of approximately 5mm × 5mm. She was finally diagnosed with colonic telangiectasia. Conclusion Colonic telangiectasia, also known as colonic vascular dysplasia, is more common in elderly patients. It is mostly asymptomatic, and gastrointestinal bleeding is an occasional symptom. Electronic colonoscopy is an important diagnostic method for colonic telangiectasia, and lesions are more common in the right colon. Asymptomatic patients do not require treatment, and those with concurrent bleeding may consider medications or local hemostasis under endoscopy.

    Objective To systematically evaluate the clinical significance of serum total bilirubin (STB) in patients with inflammatory bowel disease (IBD). Methods Case-control studies on the correlation between STB and IBD published from their inception to November 2022 were searched in online databases, including the PubMed, Embase, Web of Science, Cochrane Library, CNKI, VIP, Wanfang, and Chinese Biomedical Databases (CBM). The quality of recruited articles was assessed using the Newcastle-Ottawa Scale (NOS). RevMan 5.4.1 and Stata13.1 were used for data analysis. Results A total of 14 articles, involving 6067 participants in 18 case-control studies (2972 in IBD group and 3905 in control group) were enrolled in this meta-analysis. STB was significantly lower in IBD patients than that of controls (SMD=-0.80, 95%CI:-0.99, -0.61, P<0.01). STB level in the active stage of IBD was significantly lower than that in remission stage (SMD=-0.76, 95%CI:-1.33, -0.19, P=0.009). STB decreased with the increase of IBD severity (mild vs moderate: SMD=-0.35, 95%CI:-0.52,-0.18, P<0.01; moderate vs severe: SMD=-0.59, 95%CI:-0.78, -0.39, P<0.01; mild vs severe: SMD=-0.88, 95%CI:-1.10, -0.66, P<0.01). STB level was negatively correlated with erythrocyte sedimentation rate (ESR) (r=-0.41, 95%CI:-0.45, -0.35, P<0.01), C-reactive protein (CRP) (r=-0.37, 95%CI:-0.48, -0.26, P<0.01) and clinical score (r=-0.54, 95%CI:-0.70, -0.39; P<0.01), and positively correlated with hemoglobin (Hb)(r=0.45, 95%CI:0.40, 0.50; P<0.01). The risk of IBD in patients with low-level STB within the normal range was 3.15 times higher than that of patients with high-level STB (OR=3.15, 95%CI:2.24, 4.44, P<0.01). Conclusion Low-level STB within the normal range is correlated with the increased risk, disease activity and severity of IBD, which may have reference values for clinical evaluation of IBD.

    Objective To evaluate the risk of pancreatic cancer (PC) in patients with type 2 diabetes mellitus (T2DM) who are treated with sitagliptin. Methods Articles reporting the risk of PC in T2DM patients treated with sitagliptin published before July 10, 2022 were searched in the online databases, including EMBASE, MEDLINE, the Cochrane Library, PubMed. STATA 12.0 software was used for meta-analysis. Two investigators were independently responsible for article screen, data collection and quality assessment. Results A total of 11 randomized controlled trials involving 33, 360 T2DM patients were identified. Meta-analysis using a fixed-effect model showed that sitagliptin treatment did not significantly increase the risk of PC in T2DM patients ( R R=0.74, 95% C I: 0.45-1.21, P=0.225). Subgroup analyses showed that the monotherapy ( R R=0.82, 95% C I: 0.39-1.71, P=0.600) and combination regimen of sitagliptin ( R R=0.68, 95% C I: 0.35-1.31, P=0.244) did not significantly increase the risk of PC in T2DM patients. Conclusion Sitagliptin treatment is not associated with the increase in the risk of PC.

    Objective To systematically evaluate the relationship between the expression of human epidermal growth factor receptor-2 (HER-2) and clinicopathologic featurests in hepatocellular carcinoma (HCC). Methods Case-control studies regarding the expression of HER-2 in HCC were searched from PubMed, CNKI, Wanfang database and VIP database from establishment of the database to May 2023. Literature screening, data extraction and risk-of-bias assessment were independently performed by two researchers. Meta-analysis was performed using Revman5.3 software. Results Thirty one case-control studies representing 2558 patients were included. Meta-analysis showed that the positive rate of HER-2 in HCC cases was significantly higher than that in control cases (54.3% vs 50.5%, O R=1.87, 95% C I: 1.13-3.10, P=0.01). The expression of HER-2 in HCC cases in age ( O R=0.48, 95% C I: 0.25-0.94, P=0.03), differentiation degree( O R=2.61, 95% C I: 1.84-3.69, P<0.01), tumor diameter ( O R=1.93, 95% C I: 1.25-2.98, P=0.003), blood metastases ( O R=5.42, 95% C I: 3.15-9.31, P<0.01), clinical stage ( O R=2.02, 95% C I: 1.39-2.94, P=0.0003), portal vein invasion ( O R=1.73, 95% C I: 1.11-2.72, P=0.02) and serum HBsAg ( O R=2.22, 95% C I:1.55-3.18, P<0.01) were statistically significant. Conclusion HER-2 is differentially expressed in HCC, and its expression level is related to clinicopathological features of HCC, suggesting a important role in the pathogenesis of HCC, and which can provide a higher level of evidence for the diagnosis and molecular targeted therapy of HCC in the future. However, the evidence for its quantity and quality remains limited, the results need to be verified by more high-quality studies.

    Objective To explore the clinical features and treatment of immunoglobulin G4 (IgG4)-related diseases characterized by increased immunoglobulin E (IgE) level and eosinophilic count with multiple lymphadenopathy. Methods The clinical data, diagnosis and treatment process of a patient with IgG4-related disease characterized by increased IgE level and eosinophilic count with multiple lymphadenopathy were retrospective analyzed, and related literatures were reviewed. Results A 24-year-old male patient was admitted with the enlargement of bilateral inguinal lymph nodes for more than 2 years. The clinical manifestations, IgG4 test and pathology results suggested the diagnosis of IgG4-related disease. The therapeutic regimen was 20 mg prednisone orally once a day and 5 mg Tofacitinib citrate tablets orally twice a day. The dosage was adjusted according to the blood test and ultrasound results, and the symptoms of the patient were significantly improved at the final follow-up visit. Conclusion IgG4-related diseases are often characterized by significantly elevated serum IgG4 levels and lump-like lesions. Increased IgE level and eosinophil count are rarely observed in cases of IgG4-related diseases, although their important roles have been recently identified. Glucocorticoids are the first-line drugs, and targeted drugs like Tofacitinib may have potential therapeutic effects on IgG4-related diseases, which expand the new idea of the treatment.

    Objective To systematically evaluate the risk for readmission in patients with chronic obstructive pulmonary disease (COPD) and provide references for the construction and optimization of prediction model.Methods The literatures on the risk prediction model for COPD readmission were independently screened in China National Knowledge Infrastructure (CNKI), VIP, WanFang Data, Cochrane Library, PubMed, Embase databases from database inception to November 22, 2023 by two researchers. After extracting data, the bias risk and applicability of the models were evaluated using the PROBAST tool. Results Twelve cohort studies representing 21 models were finally included. Eleven studies reported the area under a receiver operator characteristic (ROC) curve (AUC) and one study for the C-index. The AUC ranged from 0.603 to 0.917, with AUC>0.7 for 16 models. Six studies conducted model calibration and eight studies for internal or external validation. The overall applicability of the 12 studies was good, but with a high risk of bias, mainly in the analysis domain. The included studies had significant differences in the predictive factors, with the most common predictive factors of lung function indicators, Charlson comorbidity index, times of hospitalization due to a history of acute exacerbation during the previous year, eosinophil levels, and inhaled drug therapy. Conclusion The performance of the included models varied greatly, with good applicability but high risk of bias. Due to the incomplete screening method, and there were significant differences in predictive factors of the included studies. Future prediction models should focus on lung function, Charlson comorbidity index, times of hospitalization due to a history of acute exacerbation during the previous year, eosinophil levels, and inhaled drug therapy.

    Objective The efficacy of tonsillectomy in immunoglobulin A nephropathy (IgAN) still remains controversial. This meta-analysis aims to evaluate the efficacy of tonsillectomy as an auxiliary or independent therapy and provide more evidence-based evidence for its clinical application. Methods We retrieved the literatures about the efficacy of tonsillectomy in IgAN published in Pubmed, Embase, ScienceDirect, Cochrane library, Web of science, Chinese National Knowledge Infrastructure (CNKI), VIP, China Biomedical Literature Database (CBM) and Wanfang databases from the time of establishment to November 1, 2022. The rate of proteinuria remission, hematuria remission, complete remission (CR) and end-stage renal disease (ESRD) were taken as observation points and meta-analyse were conducted by using Stata 12.0 software. Results A total of 36 studies representing 5797 patients with primary IgAN were ultimately enrolled. Meta-analysis showed that compared with drug therapy alone, tonsillectomy, as auxiliary or independent therapy, significantly improved proteinuria remission rate (OR=4.44, 95%CI: 3.14-6.27), hematuria remission rate (OR=5.11, 95%CI: 2.92-8.93) and CR rate (OR=3.32, 95%CI: 2.79-3.96), and significantly reduced incidence of ESRD (OR=0.24,95%CI: 0.17-0.33). Conclusion As auxiliary or independent treatment, tonsillectomy may induce clinical remission and inhibit the progression of ESRD in patients with IgAN and more attention should be paid to its application value in clinic.

    Objective To explore the correlation between oral health status and the risk of cognitive dysfunction by meta-analysis. Methods Cohort studies on the correlation between oral health status and cognitive function from inception to August 2023 were searched in PubMed, Web of Science, EMBASE, Scopus, Chinese National Knowledge Infrastructure (CNKI), China Biomedical Literature Database (CBM), Wanfang, VIP and Duxiu databases. Two reviewers independently screened literatures, extracted data and evaluated the quality of included studies. Meta-analysis was performed using RevMan 5.3 and Stata 17.0 software. Results A total of 34 cohorts were included. The results of meta-analysis showed that the risk of cognitive impairment in the elderly with poor oral health status was significantly higher than that in the elderly with good oral health status (RR=1.31, 95%CI 1.18-1.46, P<0.01). The results of subgroup analysis showed that there were significant differences in periodontitis disease, posterior occlusal support, dentition status, and tooth loss (P<0.05), but there was no significant difference in the oral frailty (RR=1.32, 95%CI 0.96-1.81, P=0.09). There was no significant difference in the risk of oral health status and cognitive impairment in the subgroup with a follow-up time>10 years (RR=1.01, 95%CI 0.83-1.23, P=0.90), but a significant difference was detected in the subgroup with a follow-up time ≤10 years (RR=1.48, 95%CI 1.32-1.67, P<0.001). There was no significant difference in the risk of oral health status and cognitive impairment in the moderate quality subgroup (RR=1.05, 95%CI 0.91-1.20, P=0.51), but a significant difference was detected in the high quality subgroup (RR=1.35, 95%CI 1.21-1.51, P<0.01). Conclusion Oral health status is associated with the risk of cognitive dysfunction.
