ObjectiveTo investigate the relationship between TypeⅠHelicobacter pylori （H. pylori） infection and the risk of colorectal neoplasms （CRN） in patients attending gastroenterology clinics， and to evaluate its predictive value for CRN in this population. MethodsWe included 2 148 patients presenting to the Department of Gastroenterology， with 677 assigned to the CRN group and 1 471 to the non-CRN group.H.pylori antibody typing was performed using Western blot， with typeⅠdefined as positivity for CagA and/or VacA antibodies， and type II as positivity only for UreA/B antibodies. Statistical analyses included univariate screening， multivariate logistic regression， and receiver operating characteristic （ROC） curve evaluation. ResultsTypeⅠH.pylori seropositivity was significantly more prevalent in the CRN group than in the non-CRN group （54.51% vs 45.62%， P_adjust<0.05）. No significant differences were observed for type Ⅱ H.pylorior seronegative subjects. The CRN group had higher proportions of males， hypertension， diabetes， smoking， and alcohol use， as well as elevated body mass index， fasting plasma glucose， triglycerides， and uric acid， along with lower high-density lipoprotein levels （all P<0.05）. Multivariate analysis confirmed typeⅠH.pylori （OR=1.303）， alcohol consumption （OR=2.315）， male （OR=1.592）， and age （OR=1.048） as independent risk factors for CRN. Although type I H.pylori alone showed limited predictive value （AUC=0.544）， a combined model incorporating alcohol use， age， and sex demonstrated significantly improved discriminative ability （AUC=0.681， sensitivity 59.1%， specificity 68.2%）. ConclusionTypeⅠH. pylori infection predicts the risk of CRN in gastroenterology patients. Assessing it can help to optimize the identification of high-risk individuals and inform targeted screening strategies.

BACKGROUND: The effect of the interval between previous Helicobacter pylori (H. pylori) eradication and rescue treatment on therapeutic outcomes remains unknown. The aim of this study was to investigate the association between eradication rates and treatment interval durations in H. pylori infections. METHODS: This prospective observational study was conducted from December 2021 to February 2023 at six tertiary hospitals in Shandong, China. We recruited patients who were positive for H. pylori infection and required rescue treatment. Demographic information, previous times of eradication therapy, last eradication therapy date, and history of antibiotic use data were collected. The patients were divided into four groups based on the rescue treatment interval length: Group A, ≥4 weeks and ≤3 months; Group B, >3 and ≤6 months; Group C, >6 and ≤12 months; and Group D, >12 months. The primary outcome was the eradication rate of H. pylori . Drug compliance and adverse events (AEs) were also assessed. Pearson's χ2 test or Fisher's exact test was used to compare eradication rates between groups. RESULTS: A total of 670 patients were enrolled in this study. The intention-to-treat (ITT) eradication rates were 88.3% (158/179) in Group A, 89.6% (120/134) in Group B, 89.1% (123/138) in Group C, and 87.7% (192/219) in Group D. The per-protocol (PP) eradication rates were 92.9% (156/168) in Group A, 94.5% (120/127) in Group B, 94.5% (121/128) in Group C, and 93.6% (190/203) in Group D. There was no statistically significant difference in the eradication rates between groups in either the ITT ( P = 0.949) or PP analysis ( P = 0.921). No significant differences were observed in the incidence of AEs ( P = 0.934) or drug compliance ( P = 0.849) between groups. CONCLUSION: The interval duration of rescue treatment had no significant effect on H. pylori eradication rates or the incidence of AEs. REGISTRATION ClinicalTrials.gov , NCT05173493.

Oral squamous cell carcinoma(OSCC)is a malignant lesion originating from the oral mucosal squamous epithelium,account-ing for over 80％of oral and maxillofacial malignancies.Key etiological factors include tobacco,alcohol abuse,and betel quid chewing.In China,its incidence has shown an overall upward trend,posing a significant threat to public health.OSCC exhibits high local invasive-ness,making early diagnosis critical for improving prognosis.Its clinical management requires close multidisciplinary collaboration among oral and maxillofacial surgery,head and neck surgery,radiation oncology,medical oncology,reconstructive surgery,radiology,patholo-gy,and nutritional support teams.Given the increasing disease burden of OSCC and rapid development of multidisciplinary collaborative models,an expert panel has formulated this integrated management consensus based on evidence-based medicine and extensive deliber-ation.Centered on the'Prevention-Screening-Diagnosis-Treatment-Rehabilitation'framework,the consensus provides comprehensive guidance for the entire disease course of OSCC patients,aiming to standardize clinical practice.

Objective:To analyze and evaluate the current situation of unplanned extubation of midline catheters, and to provide a basis for the prevention of unplanned extubation of midline catheters.Methods:PubMed, Embase, The Cochrane Library, Web of Science, CINAHL, Scopus, China Biomedical Database, China National Knowledge Infrastructure, Wanfang Database, and VIP database were searched by computer to collect studies on the incidence of unplanned extubation of midline catheters from inception to February, 2024. Two reviewers independently screened the literature, extracted the data, and assessed the risk of bias of included studies, and then the meta-analysis was performed by Stata 18.0 software.Results:A total of 35 literatures were included, with a total sample size of 7 202 cases. Meta-analysis results showed that the overall incidence of unplanned catheter extubation was 15.3% (95% CI 12.3%-18.3%). Pain was the most common cause of unplanned extubation, occurring at 8.3% (95% CI 3.3%-13.2%). Subgroup analysis showed that the incidence of unplanned extubation in patients <18 years old, 18-59 years old, and ≥60 years old were 17.0%, 10.9%, 18.0%, respectively. The incidence of unplanned extubation in high-income countries and middle and low-income countries were 24.4% and 3.3%, respectively. The incidence of unplanned extubation of catheter tips near axillary vein, chest wall segment axillary vein, or subclavian vein were 19.3% and 3.6%, respectively. Conclusions:The incidence of unplanned extubation of midline catheters is high. Among them, the incidence of unplanned extubation was higher in patients ≥60 years of age, high-income countries, and patients with catheter tips placed near axillary veins. It is suggested that medical staff should pay attention to this and formulate relevant measures to prevent the occurrence of unplanned extubation.

AIM:This study aims to investigate the protective effect of Buyang-Huanwu decoction(BYHWD)on cerebral ischemia-reperfusion injury(CIRI)in rats,focusing on its role in regulating the autophagy of cerebral micro-vascular endothelial cells(BMECs).METHODS:(1)We established a rat model of middle cerebral artery occlusion/re-perfusion(MCAO/R)and divided the subjects into four groups:sham group,model(MCAO/R)group,BYHWD group,and 3-n-butylphthalide(NBP)group.Neurological deficits were assessed using the Zea Longa score,while the volume of cerebral infarction was measured through 2,3,5-triphenyltetrazolium chloride(TTC)staining.Pathological damage in the ischemic penumbra was evaluated using HE staining,and blood-brain barrier(BBB)permeability was assessed by Evans blue(EB)staining.The ultrastructure of BMECs was analyzed by transmission electron microscopy,and the co-expres-sion and positive cell rate of microtubule-associated protein 1 light chain 3(LC3)in BMECs were determined through im-munofluorescence double staining.Additionally,the protein expression levels of ZO-1,claudin-5 and occludin in the cor-tical region of the ischemic penumbra in rats were examined using Western blot analysis.(2)A rat BMEC model of oxy-gen-glucose deprivation/reoxygenation(OGD/R)was also established.Rat BMECs were categorized into normal control(CON),OGD/R,dimethyl sulfoxide(DMSO),rapamycin and 3-methyladenine groups to observe autophagy levels by monodansylcadaverine(MDC)staining.Furthermore,rat BMECs were divided into CON,OGD/R,BYHWD-containing serum(BHDS)and NBP groups.The cell autophagy was assessed by MDC staining and Western blot,while cell viability was measured by CCK-8 assay.RESULTS:(1)The rats in MCAO/R group exhibited significantly higher neurological scores(P＜0.01)and increased cerebral infarction volumes(P＜0.01)compared with sham group.Severe damage in the ischemic penumbra was observed,characterized by disordered tissue structure,widened intercellular spaces,and compro-mised cellular integrity.The EB dye permeability was notably elevated(P＜0.01),and BMECs showed structural destruc-tion,including damaged cell membranes,swollen Golgi apparatus,dilated endoplasmic reticulum vesicles,and damaged mitochondria.The ratio of LC3+CD31+/CD31+and the protein levels of ZO-1,claudin-5 and occludin were significantly el-evated(P＜0.01).In contrast,the rats in BYHWD and NBP groups demonstrated lower neurological scores(P＜0.01)and reduced cerebral infarction volumes(P＜0.01).Furthermore,EB permeability decreased(P＜0.01),BMEC morphol-ogy improved,and the protein expression levels of ZO-1,claudin-5 and occludin increased(P＜0.05).(2)Rat BMECs in OGD/R group had a significantly elevated autophagy level compared with CON group(P＜0.01),with increased expres-sion of LC3 and beclin-1 proteins and decreased level of P62 protein(P＜0.05).Notably,the cells in BHDS and NBP groups displayed decreased autophagy level compared with OGD/R group,with increased cell viability(P＜0.01),re-duced LC3 and beclin-1 protein expression,and increased P62 protein expression(P＜0.05).CONCLUSION:Buyang-Huanwu decoction alleviates cerebral ischemia-reperfusion injury in rats by inhibiting the autophagy of cerebral microvas-cular endothelial cells.

Oropharyngeal squamous cell carcinoma(OPSCC)is a malignant tumor originating from the squamous epithelium of the oro-pharyngeal mucosa,accounting for more than 90％of oropharyngeal malignancies.In recent years,human papillomavirus(HPV)infec-tion has become one of the primary etiological factors of oropharyngeal squamous carcinoma.The incidence of HPV-associated oropharyn-geal squamous carcinoma has been rising annually,with a noticeable trend toward younger populations,posing a significant threat to hu-man health.Due to the distinct biological behavior and clinical characteristics of HPV-associated oropharyngeal squamous carcinoma com-pared to its non-HPV-related counterpart,the diagnostic and treatment strategies for oropharyngeal squamous carcinoma have undergone substantial changes.Prevention and screening for oropharyngeal squamous carcinoma are of critical importance.The diagnostic and treat-ment process involves multi-disciplinary collaboration,including oral and maxillofacial surgery,otolaryngology,head and neck surgery,oncology,radiology and pathology.Based on evidence from clinical practice,a comprehensive,integrated diagnostic and therapeutic ap-proach has been established,centered around the concept of"prevention,screening,diagnosis,treatment,and rehabilitation",covering the entire patient lifecycle and providing a valuable reference for clinical practice.

Objective To explore the potential prognostic factors of patients with acute ischemic stroke(AIS)after undergoing endovascular mechanical thrombectomy and to construct an effective predictive model.Methods A retrospective analysis of clinical data was conducted on 202 patients with anterior circulation large vessel occlusion AIS from 2 stroke centers.All patients received endovascular mechanical thrombectomy treatment,with treatment and follow-up lasting at least 90 d.Basic demographic characteristics,medical records,and baseline blood biomarker data were collected,and the potential prognostic indicators for AIS after 90 d were screened using least absolute shrinkage and selection operator(LASSO)-logistic regression analysis.Results It was found that alcohol drinking(P=0.029),hypertension(P=0.001),diabetes mellitus(P=0.021),stroke or transient ischemic attack(P=0.049),systolic blood pressure on admission(P=0.009),diastolic blood pressure on admission(P=0.038),blood glucose(P=0.003),white blood cell count(P=0.001),neutrophil count(P=0.001),fibrinogen(P=0.010),systemic immune-inflammation index(P=0.008)and neutrophil-to-lymphocyte ratio(NLR)(P＜0.001)were associated with adverse clinical outcomes.Nine significant prognostic determinants were screened through LASSO-logistic regression analysis.Multivariate logistic regression analysis revealed that male sex(P=0.008),smoking history(P=0.013),hypertension(P=0.011),lymphocyte(P=0.028),fibrinogen(P=0.016),and NLR(P＜0.001)were significant predictive factors for poor prognosis in AIS patients after endovascular thrombectomy treatment.The constructed prognostic model had an accuracy of 76.2％,a sensitivity of 78.2％,a specificity of 71.7％,and a positive predictive value of 86.7％.Conclusion The predictive model established in this study can assist clinicians in identifying high-risk patients with AIS who have undergone endovascular thrombectomy,and it provide guidance for formulating individualized treatment strategies.
