Objective To improve the efficiency and accuracy of videonystagmography calibration test results while enabling effective recognition of saccadic undershoot waveform by developing a dual-stream architecture-based deep learning model. Methods A vestibular function calibration test recognition model with cross-modal feature fusion was constructed by integrating vision transformer (ViT) and a modified ConvNeXt convolutional network. The model utilized trajectory pictures and spatial distribution maps as inputs, employed a multi-task learning framework to classify calibration data, and to directly evaluate undershoot waveform. Results The model showed outstanding performance in assessing calibration compliance. The accuracy, sensitivity, specificity of the model in left side, middle, and right side were all greater than 90%, and AUC values were all greater than 0.99, with 97.66% of optimal accuracy (middle), 98.98% of optimal sensitivity (middle), 96.87% of optimal specificity (right side), and 0.997 of AUC (right side). The model also showed promising performance in undershoot waveform recognition with 87.50% of accuracy, 89.66% of sensitivity, 85.71% of specificity, 86.67% of F1 score, and 0.931 of AUC. Conclusions The proposed method not only significantly enhances the efficiency and accuracy of calibration test results, but also provides a novel solution for undershoot waveform recognition.

Objective To investigate the factors influencing the efficacy of intravesical Bacille Calmette-Guérin(BCG)instillation after transurethral resection of bladder tumor(TURBT)in patients with intermediate-and high-risk non-muscle invasive bladder cancer(NMIBC),and to construct a prediction model for recurrence after BCG treatment.Methods A retrospective cohort study was conducted on the subjected patients diagnosed with intermediate-and high-risk NMIBC undergoing TURBT followed by standard BCG instillation.The 110 patients treated in Department of Urology of Army Medical Center of PLA from January 2018 to December 2023 were assigned into a training set,while the 52 patients treated at Department of Urology of General Hospital of Central Theater Command from January 2015 to December 2020 were into an external validation set.A total of 17 variables were included and analyzed.Univariate and multivariate Cox regression analyses were performed to identify factors associated with recurrence after BCG instillation,and nomograms were plotted to predict 1-year,3-year,and 5-year recurrence-free survival(RFS).Calibration curve,decision curve analysis(DCA),and receiver operating characteristic(ROC)curve analysis were conducted for internal and external validation to evaluate the predictive performance and clinical utility of the model.Results In the training set,26 patients(23.64%)experienced recurrence during the follow-up period,with a median RFS of 32.00(18.00～50.50)months.Univariate Cox regression analysis suggested that platelet count,eosinophil to lymphocyte ratio(ELR),neutrophil to lymphocyte ratio(NLR),platelet to lymphocyte ratio(PLR),systemic immune inflammation(SII)index,and neutrophil-monocyte to lymphocyte ratio(NMLR),pathological T1 stage(pT1)tumor and hemoglobin,albumin,lymphocyte,and platelet(HALP)score were potential factors influencing recurrence after BCG instillation.Multivariate Cox regression analysis identified high HALP score(HR=0.185,95%CI:0.046～0.736,P=0.017)as an independent protective factor,while high ELR(HR=3.599,95%CI:1.505～8.608,P=0.004)and pT1 stage(HR=3.240,95%CI:1.191～8.818,P=0.021)were independent risk factors for recurrence.Based on this,a nomogram prediction model was constructed.The calibration curves demonstrated good agreement between predicted and actual 1-,3-,and 5-year recurrence risks.Decision curve analysis indicated clinical utility across a wide threshold probability range.In the training set,the model showed strong predictive performance for 1-(AUC=0.842),3-(AUC=0.847),and 5-year(AUC=0.887)recurrence risks,which was further validated in the external cohort.Conclusion Higher HALP score prior to BCG instillation therapy is a protective factor against tumor recurrence,while higher ELR and pT1 stage are risk factors.Our nomogram prediction model based on HALP score,ELR and pathological T stage,can identify individuals at high risk of recurrence after BCG instillation therapy.

Objective To investigate risk factors for residual lesions after initial transurethral resection of bladder tumors(TURBT)and risk factors for tumor recurrence after second TURBT in patients with non-muscle-invasive bladder cancer(NMIBC)in order to provide reference for clinical management.Methods A case-control study design was adopted to include 120 NMIBC patients who underwent initial TURBT and then second surgery within 2～8 weeks in our department from January 2017 to January 2025.Based on the presence of residual lesions after the initial TURBT or not,the patients were divided into a residual lesion group(n=34)and a non-residual lesion group(n=86).Chi-square test and multivariate logistic regression analysis were performed to identify potential risk factors for residual lesions following the initial TURBT.Univariate and multivariate Cox regression models were used to analyze potential risk factors for tumor recurrence after the second TURBT.Results The residual lesion rate after initial TURBT was 28.33％.Chi-square test analysis revealed that tumor stage T1(Chi-square=5.756,P=0.016)and broad tumor base(Chi-square=4.331,P=0.037)were factors influencing residual lesions after initial TURBT.Multivariate logistic regression analysis identified tumor stage T1(OR=3.047,95％CI:1.128～8.226,P=0.028)as an independent risk factor for residual lesions after initial TURBT.The tumor recurrence rate after second TURBT was 17.5％.Multivariate Cox regression analysis identified tumor stage T1(OR=4.258,95％CI:1.248～14.532,P=0.021),intravesical chemotherapy instillation after second TURBT(OR=3.539,95％CI:1.284～9.752,P=0.015),history of urinary system tumors(OR=3.002,95％CI:1.145～7.873,P=0.025)and high platelet-to-lymphocyte(PLR)ratio(OR=2.798,95％CI:1.115～7.023,P=0.028)as independent risk factors for tumor recurrence after second TURBT.Conclusion Tumor stage T1 and broad tumor base are risk factors for residual lesions after initial TURBT,while tumor stage T1,intravesical chemotherapy instillation after second TURBT,history of urinary system tumors and high PLR ratio are risk factors for tumor recurrence after second TURBT.Comprehensive analysis on above 4 indicators can effectively assess the risk of tumor recurrence in NMIBC patients following second TURBT,and timely early medical intervention is beneficial for improving patient outcomes.

Oroxylin A (OA) is a natural flavonoid primarily derived from the plants Oroxylum indicum and Scutellaria baicalensis. Currently, OA is obtainable through chemical synthesis and exhibits polypharmacological properties, including anti-cancer, anti-inflammatory, anti-microbial, and multi-organ protective effects. The first-in-class drug OA tablets are presently undergoing phase Ib/IIa clinical trials for hepatocellular carcinoma (HCC) treatment. Substantial evidence suggests that OA demonstrates therapeutic potential against various hepatic and gastrointestinal (GI) disorders, including HCC, hepatic fibrosis, fatty liver disease, hepatitis, liver injury, colitis, and colorectal cancer (CRC). OA exerts its therapeutic effects primarily by modulating several crucial signaling pathways, including those associated with apoptosis, oxidative stress, inflammation, glucolipid metabolism, and fibrosis activation. The oral pharmacokinetics of OA is characterized by phase II metabolism, hydrolysis, and enterohepatic recycling. This review provides a comprehensive overview of the critical stages involved in the development of OA tablets, presenting a holistic perspective on the progression of this first-in-class drug from preclinical to clinical phases. It encompasses the synthesis of active pharmaceutical ingredients, pharmacokinetics, pharmacological efficacy, toxicology, drug delivery, and recent advancements in clinical trials. Importantly, this review examines the potential mechanisms by which OA may influence the gut-liver axis, hypothesizing that these interactions may confer health benefits associated with OA that transcend the limitations posed by its poor bioavailability.

Background and purpose:Rectal cancer is one of the malignant tumors that seriously harm human health in the world,ranking third in incidence and second in mortality.With the development of social and economic level,the incidence and mortality of colorectal cancer in China are increasing,and China becomes one of the countries with high incidence of colorectal cancer disease in the world.The recommended treatment for locally advanced rectal cancer is neoadjuvant chemoradiotherapy combined with surgery,which greatly improves the prognosis of patients.However,intestinal adverse reactions such as diarrhea caused by neoadjuvant chemoradiotherapy are increased,and some patients are forced to delay or interrupt treatment due to serious side effects.Amifostine is a broad-spectrum normal cell protective agent,which has good protective effect against various radiochemotherapy toxicity.We conducted a retrospective analysis of patients with locally advanced rectal cancer who received neoadjuvant radiotherapy combined with irinotecan concurrent chemotherapy to investigate whether concurrent use of amifostine alleviated gastrointestinal and hematological toxicities.Methods:A retrospective cohort analysis was used in this study.Clinical data of patients with locally advanced rectal cancer who received neoadjuvant chemoradiotherapy at the Affiliated Cancer Hospital of Fudan University during the period of discharge from January 1,2018 to December 31,2019 were retrospectively collected.The patients were divided into 2 groups by whether amifostine was used during the same period.The main purpose of the study was to analyze whether amifostine can reduce gastrointestinal and hematological toxicities,and secondary objectives included whether amifostine could alter tumor marker levels,mesorectal fascia invasion(MRF)positive rate,extramural vascular invasion,positive rate of EMVI and pathological complete response(pCR).Using SAS9.4 statistical software,the normality test was carried out for continuous variables.The rank sum test of Wilcoxon was performed when the diarrhea grade did not conform to normal distribution.Analysis of variance was performed for intra-group comparison,and Wilcoxon rank sum test was performed for inter-group comparison.Because of the imbalance between groups,the difference between the two groups was compared using a generalized linear model.This study strictly followed the STrengthening the Reporting of OBservational studies in Epidemiology(STROBE)guidelines to ensure the transparency of the research methodology and the reliability of the results.Results:Finally,154 eligible patients were included,of whom 78 were in the amifostine group and 76 were in the control group.The highest grade of diarrhea in amifostine group was 1.00(1.00,1.00),lower than that in control group(2.00,3.00),and the difference between groups was statistically significant(P＜0.01).After radiotherapy,white blood cell count(WBC),hemoglobin(HB)and absolute neutrophil count(ANC)from the two groups were obtained.ANC and platelet count(PLT)showed no statistically significant difference(P＞0.05),and the lowest values of WBC,RBC and PLT did not have statistically significant difference between the two groups during neoadjuvant period(P＞0.05).Amifostine may not alleviate hematological toxicity.Carbohydrate antigen 72-4(CA72-4)(Z=2.22,P=0.03),carbohydrate antigen 50(CA50)(Z=-2.49,P=0.01)and carbohydrate antigen 24-2(CA24-2)had statistically significant difference(Z=-2.29,P=0.02).There were no significant differences in MRF positive rate(P=0.11),EMVI positive rate(P=0.61)and pCR rate(P=0.94)between the two groups.Conclusion:Concurrent administration of amifostine in patients with locally advanced rectal cancer receiving neoadjuvant chemoradiotherapy can reduce gastrointestinal toxicity and reduce the levels of tumor markers CA72-4,CA50 and CA24-2.However,it may have no significant effect on improving hematological toxicity,MRF and EMVI positive rate and pCR rate.

Existing epidemiologic and clinical studies have demonstrated that obesity is associated with the risk of a variety of cancers. In recent years, an increasing number of experimental and clinical studies have unraveled the complex relationship between obesity and cancer risk and the underlying mechanisms. Obesity-induced abnormalities in immunity and biochemical metabolism, including chronic inflammation, hormonal disorders, dysregulation of adipokines, and microbial dysbiosis, may be important contributors to cancer development and progression. These contributors play different roles in cancer development and progression at different sites. Lifestyle changes, weight loss medications, and bariatric surgery are key approaches for weight-centered, obesity-related cancer prevention. Treatment of obesity-related inflammation and hormonal or metabolic dysregulation with medications has also shown promise in preventing obesity-related cancers. In this review, we summarize the mechanisms through which obesity affects the risk of cancer at different sites and explore intervention strategies for the prevention of obesity-associated cancers, concluding with unresolved questions and future directions regarding the link between obesity and cancer. The aim is to provide valuable theoretical foundations and insights for the in-depth exploration of the complex relationship between obesity and cancer risk and its clinical applications.

Objective:To investigate the predictive value of atherogenic index of plasma (AIP) in the assessment of acute pancreatitis (AP).Methods:598 patients diagnosed with AP admitted to the Affiliated Hospital of Yangzhou University between January 2016 and December 2020 were recruited and divided into severe acute pancreatitis group (SAP group, n=57) and non-severe acute pancreatitis group (non SAP group, n=541) according to the Atlanta Classification (2012 revision). General clinical data and related biochemical indicators of all enrolled patients were collected, and Bedside Index of Acute Pancreatitis Severity (BISAP) score, Ranson score and CT Severity Index (CTSI) score were performed. The risk factors of SAP were analyzed by logistic regression. Receiver operating characteristic (ROC) curve was used to analyze the evaluation value of AIP and various scoring systems on the severity of pancreatitis. Results:The AIP, white blood cell (WBC), neutrophil count (NEUT), fasting blood glucose (FBG), serum total cholesterol (TC) level, proportion of hyperlipidemia, proportion of diabetes, Ranson score, BISAP score, CTSI score of patients in SAP group were higher than those in non SAP group, and the difference was statistically significant (all P<0.05). Multivariate logistic regression analysis showed that AIP was an independent risk factor for SAP ( P<0.05). ROC curve showed that the are under the curve (AUC) of SAP predicted by AIP was 0.706(95% CI: 0.631-0.782, P<0.001). Conclusions:AIP is an independent risk factor for SAP, which helps to assess the severity of AP.

Objective:To investigate the effect of intravenous anesthesia on the detection rate of lesions in diagnostic gastroscopy.Methods:A total of 9 071 subjects who underwent diagnostic gastroscopy at the Digestive Endoscopy Center of Yangzhou University Affiliated Hospital from March 2021 to February 2022 were selected. Data were collected from the gastroscopy quality control system, including age, gender, examination physician, Helicobacter pylori infection, examination method, withdrawal time, number of images left, number of biopsies, biopsy site, gastroscopy diagnosis, pathological diagnosis, etc. They were divided into anesthesia group and general group based on the examination method, and propensity score matching (PSM) was performed on the two groups of subjects. Excluding confounding factors, the detection of lesion location and lesion type in two groups of subjects was analyzed; Simultaneously, univariate and multivariate logistic regression analysis was used to analyze the influencing factors of the detection rate of precancerous lesions and malignant tumors in the upper gastrointestinal tract.Results:After PSM, 1 655 subjects were included in both groups. In terms of lesion location, the detection rate of gastric body lesions in the anesthesia group was higher than that in the general group ( P<0.05), and the detection rate of esophageal lesions in the anesthesia group was lower than that in the general group ( P<0.05); In terms of lesion types, the detection rate of precancerous lesions such as gastric polyps, mucosal protrusions, mucosal atrophy, and intestinal metaplasia in the anesthesia group was higher than that in the general group (all P<0.05). The results of logistic regression analysis showed that intravenous anesthesia was an independent influencing factor for the detection rate of precancerous lesions and malignant tumors in diagnostic gastroscopy ( OR=1.338, 95% CI: 1.070-1.674, P<0.05). Conclusions:Intravenous anesthesia is an independent influencing factor for the detection rate of precancerous lesions and malignant tumors in diagnostic gastroscopy, and can improve the detection rate of upper gastrointestinal lesions.

Objective:To evaluate the effect of social media based behavioral intervention on promoting joint testing of HIV and syphilis in young men who have sex with men (MSM).Methods:After the recruitment, the participants who met the inclusion criteria were randomly divided (1∶1) into two groups, i.e. social media intervention group and control group. The control group was given routine voluntary counseling and testing (VCT) services. The intervention group was also given VCT services, besides; the comprehensive strategies through social media, including regular health education message and testing information sending, were given to them to strengthen the behavioral intervention. Follow up was conducted for the participants for 12 months after the intervention. The number and the proportion of young MSM receiving HIV and syphilis testing, and the reported proportion of the young MSM with sexually transmitted diseases (STD) symptoms between the intervention group and the control group were compared to evaluate the effect of the intervention.Results:A total of 315 young MSM were recruited (158 in the intervention group and 157 in the control group), in whom 248 young MSM completed the follow up. The follow-up rate was 78.7%. There was no significant difference in baseline characteristics between the intervention group and the control group (all P>0.05). The proportion of young MSM receiving more than one joint testing in the intervention group was slightly higher than that in the control group (53.2% vs. 48.4%, rate difference (RD): 4.8%, 95% CI: -7.5%-17.0%, P=0.448) without significant difference. However, in the young MSM who used condoms in the last anal sex, the proportion of those receiving more than one joint testing in the intervention group was higher than that in the control group (63.8% vs. 46.1%, RD: 17.7%, 95% CI: 1.5%-32.6%, P=0.035). In addition, the reported proportion of young MSM with STD symptoms in the intervention group was significantly lower than that in the control group (6.3% vs. 18.0%,RD: -11.7%, 95% CI: -20.6%- -3.0%, P=0.005). Conclusion:Compared with routine VCT, social media based behavioral intervention might promote joint HIV and syphilis testing in the young MSM who used condom in the study. It could significantly reduce the reporting proportion of STD symptoms, suggesting that this method can promote the AIDS and STD prevention related behaviors in young MSM.

Background: The systemic immune inflammation index (SII) is a reproducible biomarker of inflammatory process. Aims: To explore the predictive value of SII for severe acute pancreatitis (SAP). Methods: A total of 406 patients with acute pancreatitis (AP) from Jan. 2013 to Dec. 2020 at Affiliated Hospital of Yangzhou University were collected, and were divided into SAP group and non SAP group. ROC curve was drawn to evaluate the value of SII, NLR, PLR, CAR for predicting SAP. Results: Compared with non‑SAP group, SII, NLR, PLR, CAR were significantly increased in SAP group (P<0.05). When the best cut‑off value was 1 705.83, AUC of SII for predicting SAP was 0.754, the sensitivity was 75.47%, and the specificity was 69.12%. AUC of SII for predicting SAP was higher than that of PLR, CAR (Z=2.647, P=0.007; Z= 2.616, P=0.008), while no significant difference was found between SII and NLR (P>0.05). And no significant difference in AUC was found between PLR and CAR (P>0.05). Conclusions: SII is a good new hematological index that can be used to predict the severity of AP, its predictive ability is similar to NLR, better than PLR and CAR.
