In recent years, artificial intelligence(AI),a branch of computer science based on deep learning and machine learning, has advanced rapidly in the screening and clinical management of ophthalmic diseases. Its application scope has gradually expanded from the posterior segment to the anterior segment of the eye. Automated detection and interpretation frameworks incorporating multimodal imaging modalities, including slit-lamp photography and anterior and posterior segment optical coherence tomography(OCT), have demonstrated considerable potential in the identification, early diagnosis, and clinical decision support of common anterior segment diseases such as keratitis, dry eye disease, pterygium, and glaucoma. As a fundamental instrument for anterior segment examination, the slit-lamp microscope remains indispensable in routine ophthalmic practice. This review summarizes recent progress in AI-assisted anterior segment research and discusses the prospects of integrating AI with slit-lamp imaging in clinical ophthalmology.

Oral squamous cell carcinoma (OSCC) is a common head and neck malignancy. Approximately 50% to 60% of patients with OSCC are diagnosed at a locally advanced stage (clinical staging III-IVa). Even with comprehensive and sequential treatment primarily based on surgery, the 5-year overall survival rate remains below 50%, and patients often suffer from postoperative functional impairments such as difficulties with speaking and swallowing. Programmed death receptor-1 (PD-1) inhibitors are increasingly used in the neoadjuvant treatment of locally advanced OSCC and have shown encouraging efficacy. However, clinical practice still faces key challenges, including the definition of indications, optimization of combination regimens, and standards for efficacy evaluation. Based on the latest research advances worldwide and the clinical experience of the expert group, this expert consensus systematically evaluates the application of PD-1 inhibitors in the neoadjuvant treatment of locally advanced OSCC, covering combination strategies, treatment cycles and surgical timing, efficacy assessment, use of biomarkers, management of special populations and immune related adverse events, principles for immunotherapy rechallenge, and function preservation strategies. After multiple rounds of panel discussion and through anonymous voting using the Delphi method, the following consensus statements have been formulated: 1) Neoadjuvant therapy with PD-1 inhibitors can be used preoperatively in patients with locally advanced OSCC. The preferred regimen is a PD-1 inhibitor combined with platinum based chemotherapy, administered for 2-3 cycles. 2) During the efficacy evaluation of neoadjuvant therapy, radiographic assessment should follow the dual criteria of Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 and immune RECIST (iRECIST). After surgery, systematic pathological evaluation of both the primary lesion and regional lymph nodes is required. For combination chemotherapy regimens, PD-L1 expression and combined positive score need not be used as mandatory inclusion or exclusion criteria. 3) For special populations such as the elderly (≥ 70 years), individuals with stable HIV viral load, and carriers of chronic HBV/HCV, PD-1 inhibitors may be used cautiously under the guidance of a multidisciplinary team (MDT), with close monitoring for adverse events. 4) For patients with a poor response to neoadjuvant therapy, continuation of the original treatment regimen is not recommended; the subsequent treatment plan should be adjusted promptly after MDT assessment. Organ transplant recipients and patients with active autoimmune diseases are not recommended to receive neoadjuvant PD-1 inhibitor therapy due to the high risk of immune related activation. Rechallenge is generally not advised for patients who have experienced high risk immune related adverse events such as immune mediated myocarditis, neurotoxicity, or pneumonitis. 5) For patients with a good pathological response, individualized de escalation surgery and function preservation strategies can be explored. This consensus aims to promote the standardized, safe, and precise application of neoadjuvant PD-1 inhibitor strategies in the management of locally advanced OSCC patients.

Background/Aims: Liver transplantation (LT) following total hepatectomy is a life-saving treatment for hepatocellular carcinoma (HCC). The HCC recurrence after LT hinders the effectiveness of the procedure. The objective of this study is to develop a pre-operative risk stratification model based on a liquid biopsy. Methods: We conducted a comprehensive multi-omics study of 260 HCC patients from three centers, including clinical data, low-coverage whole-genome sequencing of cell-free DNA (cfDNA) from plasma, as well as whole-exome, single-nucleus RNA, and spatial transcriptomics from matched tumor and non-tumor tissues. Results: We identified cfDNA-derived copy number alteration (CNA) signatures associated with post-transplant recurrence. By integrating cfDNA-derived CNA profiles with single-cell transcriptomic data, we traced recurrence-associated cfDNA to a distinct subpopulation of malignant cells within the primary tumor. These cells were embedded in a pro-metastatic microenvironment of specialized endothelial subtypes and cancer-associated fibroblasts. Notably, most recurrence-associated lesions were detectable in cfDNA prior to liver transplantation (LT). Building on these insights, we developed the ZJU Criteria based on CNA fragments and tumor markers, a pre-LT risk prediction tool that integrates conventional clinical factors with cfDNA-derived CNA signatures, and validated it using internal and independent external cohorts. Conclusion Our findings suggest that post-transplant recurrence commonly originates from advanced subclones that emerge late during tumor evolution. The ZJU Criteria provides an accurate, non-invasive strategy that significantly improves pre-LT risk stratification and clinical decision-making for patients with HCC.

OBJECTIVE To investigate the effect and potential mechanism of toosendanin in enhancing the antileukemic activity of cytosine arabinoside against acute myeloid leukemia （AML） based on the mammalian target of rapamycin complex 1 （mTORC1） signaling pathway.METHODS Female NSG immunodeficient mice were used to establish an AML model via a single γ-ray irradiation followed by a single tail-vein injection of a U937 cell suspension. The effects of cytosine arabinoside （2.5 mg/kg）， toosendanin （1.0 mg/kg）， and cytosine arabinoside+toosendanin （2.5 mg/kg+1.0 mg/kg） on body weight， survival time， peripheral blood routine indicators， histopathological morphology， and the expressions of autophagy-related proteins were explored. Using U937 cells as the subject， the effects of cytosine arabinoside （1 μmol/L）， toosendanin （160 nmol/L）， and cytosine arabinoside+toosendanin （1 μmol/L+160 nmol/L） on the expressions of autophagy-related proteins， mTORC1 signaling pathway-related proteins and mRNAs were investigated. The targeting relationship between toosendanin and the selective autophagy ligand 1 （also known as p62） was validated， and the Gene Ontology （GO） and Kyoto Encyclopedia of Genes and Genomes （KEGG） enrichment analyses， as well as molecular docking， were performed. A p62 -knockdown U937 stable cell line was constructed， and the underlying mechanism of toosendanin-induced sensitization was verified.RESULTS Animal experiments confirmed that the combination of toosendanin and cytosine arabinoside significantly improved body weight， survival time and peripheral blood routine indicators in AML mice （ P ＜0.05）， alleviated pathological changes such as leukemic cell infiltration and focal necrosis in bone marrow， liver， and spleen tissues， and modulated the expressions of autophagy-related proteins. Cell experiments confirmed that toosendanin could reverse cytosine arabinoside-induced activation of the autophagy cascade （manifested by downregulation of the protein expressions of microtubule-associated protein 1 light chain 3B and Beclin-1， upregulation the protein expression of p62）， and might inhibit the expression of the downstream Unc-51-like autophagy activating kinase 1 （ULK1） complex （including ULK1， ULK2， autophagy-related protein 13， and FAK family interacting protein of 200 kDa） by activating the mTORC1 signaling pathway （ P ＜0.05）. The sensitizing effect of toosendanin was associated with the inhibition of autophagy and the regulation of the mTORC1 signaling pathway； it could stably bind to p62 via hydrophobic interactions. Mechanism verification experiments indicated that upon p62 knockdown， toosendanin was no longer able to activate the mTORC1 signaling pathway or inhibit autophagy.CONCLUSIONS Toosendanin may enhance chemo-sensitivity of AML cells to cytosine arabinoside by directly targeting the p62 protein， which subsequently activates the mTORC1 signaling pathway， and thereby suppresses cytosine arabinoside-induced protective autophagy.

Objective:To investigate the clinical efficacy of haploidentical high-dose in vitro non-T-cell-depleted peripheral blood hematopoietic stem cell transplantation (haplo-HDPSCT) in treating adult patients with Ph + acute lymphoblastic leukemia (Ph + ALL) . Method:This retrospective analysis was conducted on the clinical efficacy of 25 adult patients with Ph + ALL who underwent haplo-HDPSCT from July 2011 to June 2022 at our hospital. Results:This study included 25 patients with a median age of 27 (16-61) years, consisting of 12 males and 13 females. CR1 and ≥CR2 before transplantation were found in 23 and 2 cases, positive and negative minimal residual lesions were observed in 8 and 17 cases, and myeloablative conditioning and reduced-intensity conditioning were reported in 21 and 4 cases, respectively. Hematopoietic function was restored in all 25 patients after stem cell infusion. Of the 25 patients who underwent transplantation, 16 developed acute graft-versus-host disease (aGVHD). The cumulative incidence rates of Ⅱ-Ⅳ and Ⅲ-Ⅳ aGVHD were (40.4±11.3) % and (4.8±4.6) %, respectively. Four patients experienced relapse after transplantation, the cumulative relapse rates at 1 and 2 years after transplantation were (4.0±3.9) % and (14.5±7.9) %, respectively. The 2-year overall survival rate after transplantation was (81.3±8.5) % and the disease-free survival rate was (77.1±9.1) %.Conclusion:This study reveals that the unique haplo-HDPSCT protocol achieves good clinical efficacy in Ph + ALL treatment.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To explore the differences in clinicopathological features and prognosis between conventional adrenocortical carcinoma（ACC）and oncocytic ACC.Methods:The clinical and pathological data of patients with conventional ACC and oncocytic ACC who were admitted to Peking Union Medical College Hospital from March 2012 to Fabruary 2025 were retrospectively analyzed. Differences in clinical and pathological characteristics between the two groups were compared. Survival curves were plotted using the Kaplan-Meier method，and differences in survival rates were compared using the log-rank test.Results:The conventional ACC group comprised 137 cases，with a mean age of（47.5 ± 12.6）years and 37.2%（51/137）being male. The oncocytic ACC group included 22 cases，with a mean age of（49.1 ± 15.3）years and 59.1%（13/22）being male. No statistically significant differences were observed in age or gender distribution between the two groups（ P > 0.05）. The conventional ACC group exhibited a significantly higher prevalence of classic Cushing’s syndrome symptoms compared to the oncocytic ACC group［35.2%（45/128）vs. 5.3%（1/19）； χ2 = 6.876， P < 0.01］. Additionally，the proportion of hypertension was higher in the conventional ACC group［49.2%（65/132）vs. 22.2%（4/18）； χ2 = 5.319， P < 0.05］，whereas the prevalence of adrenal sex characteristics was lower［22.0%（28/127）vs. 63.2%（12/19）； χ2 = 14.043， P < 0.01］. The Ki-67 proliferation index was significantly higher in conventional ACC patients［20%（10%，40%）vs. 12%（9%，20%）； Z = -2.113， P < 0.05］. Furthermore，the conventional ACC group demonstrated a lower 5-year overall survival rate than the oncocytic ACC group（44.5% vs. 67.3%， P < 0.05）. Conclusions:Conventional ACC patients have a higher proportion of Cushing’s symptoms and hypertension，and oncocytic ACC patients have a higher proportion of adrenal sexual characteristics abnormalities. The prognosis of oncocytic ACC is better than that of conventional ACC.

Objective:To analyze the effect of one stitch technique of transverse incision and longitudinal suture in repairing secondary nasal deformity of cleft lip.Methods:A retrospective study was conducted on 127 patients who underwent the one stitch technique of transverse incision and longitudinal suture for repairing secondary nasal deformities after unilateral cleft lip surgery in the Department of Plastic and Aesthetic Surgery at Southern Hospital of Southern Medical University from October 2010 to December 2022. There were 58 males and 69 females with a median age of 26 (18-42) years. After removing the scar on the upper lip and the cartilage of the nasal septum during surgery, the affected nasal basal area was extensively separated. The lateral groove of the nasal wing and the tail edge of the nasal septum cartilage were sutured using one stitch technique with silk thread. Subsequently, the constricted affected nostril was enlarged by M-T flap. Outpatient follow-up visits were conducted at 1, 3, 6, 12 and 18 months after surgery. Two physicians and patients subjectively evaluated the postoperative outcomes, including very satisfied, satisfied, average, and poor, and the final evaluation results were included in statistical analysis.Results:During the treatment process, the patient did not experience any complications such as infection, hematoma, or incision rupture. A total of 116 cases were followed up for more than 3 months after surgery, of which 35.3% (41/116) were very satisfied, 38.8% (45/116) were satisfied, 24.2% (28/116) were generally satisfied, and 1.7% (2/116) were not satisfied. The two patients with poor results underwent another one stitch technique for adjustment, both achieving satisfactory results.Conclusion:The effect of one stitch technique of transverse incision and longitudinal suture for repairing cleft lip and secondary nasal deformities is stable and the satisfaction of patients is high.

At the beginning of the 20 th century, Karl Landsteiner discovered the ABO blood group system, which is one of the most important blood good systems in clinical practice. ABO blood group antigens are widely present not only on red blood cells but also in various other tissues, making the association between this blood group system and cancers particularly significant. Numerous studies, both domestically and internationally, have explored the relationship between ABO blood group and cancer susceptibility. Therefore, this paper primarily reviews the research on the association between ABO blood group and susceptibility to lung cancer, gastric cancer, and pancreatic cancer, providing references for clinical practice.
