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.

Nucleotide analogues (NAs) and interferon are still the first-line drugs for the treatment of chronic hepatitis B (CHB), but they still cannot completely eliminate covalently closed circular DNA (cccDNA) within hepatocytes. The clinical cure, or the disappearance of HBsAg, is the ideal goal of antiviral therapy. Although interferon therapy has a significantly greater HBsAg clearance rate and seroconversion rate than NAs, combination or sequential treatment can improve the HBsAg clearance rate and seroconversion rate to a certain extent, and only a small proportion of CHB patients can achieve clinical cure. Therefore, finding indications that predict clinical cure before and during antiviral treatment is crucial for identifying patients who are more likely to achieve HBsAg clearance at an early stage, improving clinical cure rates, and reducing treatment costs. This article reviews the research progress on predictive indicators of clinical cure of chronic hepatitis B in the past five years, explores the value of each indicator in predicting clinical cure, and provides a reference for optimizing CHB treatment strategies.

Objective:To systematically evaluate the predictive value of the reverse shock index multiplied by the Glasgow coma scale score (rSIG) for mortality of trauma patients.Methods:A comprehensive literature search was conducted to identify studies on the predictive value of rSIG for mortality of trauma patients in the following databases from inception to April 2025, including CNKI, Wanfang Data, SinoMed, PubMed, Cochrane Library, Web of Science, and Embase. Two investigators independently screened the literature, extracted data, and assessed study quality according to predefined inclusion and exclusion criteria. The Quality assessment of diagnostic accuracy studies-2 (QUADAS-2) tool was used to evaluate the risk of bias in the included studies. Meta analysis was performed using Stata 17.0 software with a bivariate mixed-effects model. The following metrics were used to assess the predictive value of rSIG for mortality in trauma patients, including sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), diagnostic odds ratio (DOR), and area under the summary receiver operating characteristic (SROC) curve (AUC). The influence of various factors on the predictive performance of rSIG was examined, including injury type, study design, region, sample size, cut-off value, rSIG measurement time, and outcome measures. Additionally, sensitivity analysis, Fagan′s nomogram, and Deeks′ funnel plot were employed to assess the robustness of the findings, clinical applicability, and publication bias.Results:A total of 15 studies involving 710 612 trauma patients were included, 26 105 of whom were deceased. Meta analysis results showed that rSIG had a pooled sensitivity of 0.78(95% CI 0.71, 0.84), a pooled specificity of 0.78(95% CI 0.68, 0.86), a pooled PLR of 3.60(95% CI 2.46, 5.27), a pooled NLR of 0.28(95% CI 0.22, 0.36), a pooled DOR of 12.70(95% CI 8.10, 19.91), and an AUC of 0.85(95% CI 0.81, 0.87) for predicting mortality of trauma patients. Subgroup analysis identified injury type as one of the major sources of heterogeneity, and the predictive specificity of rSIG was significantly higher in patients with multiple trauma (0.82) than in those with isolated traumatic brain injury (0.65) ( P<0.05). Sensitivity analysis indicated that the findings were robust and stable. Fagan′s nomogram showed that when the pre-test probability was 7%, the post-test probability of death increased to 21% in patients with low rSIG and decreased to 2% in those with high rSIG. Deeks′ funnel plots suggested no significant publication bias among the included studies ( P>0.05). Conclusion:Low rSIG has good predictive performance for mortality of trauma patients and can serve as an effective tool for early and rapid prognosis assessment with superior predictive performance in patients with multiple trauma compared to those with traumatic brain injury.

Lymph node metastasis (LNM) is a crucial risk factor influencing an unfavorable prognosis in specific cancers. Fundamental research illuminates our understanding of tumor behavior and identifies valuable therapeutic targets. Nevertheless, the exploration of fundamental theories and the validation of clinical therapies hinge on preclinical experiments. Preclinical models, in this context, serve as the conduit connecting fundamental theories to clinical outcomes. In vivo models established in animals offer a valuable platform for comprehensively observing interactions between tumor cells and organisms. Using various experimental animals, including mice, diverse methods, such as carcinogen-induced tumorigenesis, tumor cell line or human tumor transplantation, genetic engineering, and humanization, have been used effectively to construct numerous models for tumor LNM. Carcinogen-induced models simulate the entire process of tumorigenesis and metastasis. Transplantation models, using human tumor cell lines or patient-derived tumors, offer a research platform closely mirroring the histology and clinical behavior of human tumors. Genetically engineered models have been used to delve into the mechanisms of primary tumorigenesis within an intact microenvironment. Humanized models are used to overcome barriers between human and murine immune systems. Beyond mouse models, various other animal models have unique advantages and limitations, all contributing to exploring LNM. This review summarizes existing in vitro and animal preclinical models, identifies current bottlenecks in preclinical research, and offers an outlook on forthcoming preclinical models.

Objective:To study the expression of transcription factor 12 (TCF12) in colorectal cancer cells, and to explore the effects of TCF12 on proliferation, migration, and aerobic glycolysis of colorectal cancer HT-29 cells and its mechanism.Methods:After culturing, HT-29 cells were divided into a control group and a knockdown group based on treatment conditions, and were transfected with 50 nmol/L of small interfering RNA (siRNA) and TCF12 siRNA, respectively. On the basis of the knockdown group, HT-29 cells were infected with adenovirus vector overexpressing αB-crystallin (CRYAB) with an infection multiplicity of 50, which was set as the overexpression group. The relative expression of TCF12 in HT-29 cells was detected using Western blotting. The cell survival rate, cell clone number and cell migration number of HT-29 cells were detected using cell counting kit-8, clone formation assay and cell invasion assay, respectively.

The relative expression of GLUT1, HK2 and LDHA proteins in the knockdown group were all lower than those in the control group (0.38±0.05 vs 0.98±0.09, 0.12±0.03 vs 0.97±0.04, and 0.64±0.05 vs 0.99±0.06, all P<0.01). The relative expression of CRYAB, p-PI3K/PI3K and p-Akt/Akt proteins in the knockdown group were all lower than those in the control group (0.18±0.04 vs 0.92±0.03, t=11.265, P<0.01; 0.34±0.10 vs 0.92±0.04, t=18.257, P<0.01; 0.51±0.04 vs 1.11±0.07, t=13.165, P<0.01). The cell survival rate, the cell clone number and the cell migration number per unit field of view p in the overexpression group were all higher than those in the knockdown group [(97.00±6.56)% vs (45.67±6.03)%, t=12.762, P<0.01; 136.67±5.69 vs 44.33±6.03, t=22.585, P<0.01; 57.33±5.51 vs 24.67±4.51, t=25.312, P<0.01]. Glucose uptake, relative lactic acid production and ATP level in the overexpression group were all higher than those in the knockdown group [(1.25±0.08) mg/ml vs (0.51±0.05) mg/ml, t=22.164, P<0.01; (44.00±3.06)% vs (19.67±3.06)%, t=25.822, P<0.01; (21.00±2.00) μmol/L vs (9.33±1.53) μmol/L, t=18.876, P<0.01]. The relative expression level of CRYAB, p-PI3K/PI3K and p-Akt/Akt proteins in the overexpression group were all higher than those in the knockdown group (6.00±0.63 vs 0.96±0.24, t=12.79, P<0.01; 2.13±0.25 vs 0.10±0.03, t=13.90, P<0.01; 2.07±0.21 vs 0.46±0.04, t=13.17, P<0.01). Conclusions:TCF12 may promote the proliferation, migration and aerobic glycolysis of colorectal cancer cells by regulating CRYAB/PI3K/Akt signaling pathway.

In recent decades,the incidence of human papillomavirus(HPV)-associated oropharyngeal squamous cell carcinoma(OPSCC)has shown a marked increase.Significant changes have also occurred in the OPSCC diagnosis and treatment paradigm.Deter-mining HPV status prior to treatment is now essential,and radiotherapy/chemotherapy,immunotherapy,and minimally invasive surgical techniques have progressively emerged as key modalities for managing OPSCC.However,alongside these paradigm shifts,a comprehen-sive technical consensus guiding the entire diagnostic and therapeutic process for OPSCC patients is currently lacking.Given China's large population base and the rising incidence of OPSCC,an expert panel convened to develop a clinical technical consensus on OPSCC diagno-sis and management tailored to China's specific context.This consensus aims to further enhance and standardize understanding of OPSCC management techniques among relevant healthcare professionals.

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.
