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.

Objective:To investigate the effects of multimodal and multisensory stimulation training on feeding-swallowing and neurological functions in stroke patients with dysphagia.Methods:Stroke patients with dysphagia treated at Henan Provincial People's Hospital from January 2023 to October 2024 were enrolled. Patients were randomly divided into three groups according to the random number table method, with 36 patients in each group. These three groups underwent different interventions for a period of 8 weeks: multisensory stimulation intervention (stimulation group), multimodal rehabilitation training intervention (rehabilitation group), and innovative multimodal and multisensory stimulation training intervention (combined group). The Kubota water swallow test and functional oral intake scale (FOIS) were used to assess the effective improvement rate of feeding function. Differences in scores of modified Mann assessment of swallowing (MMASA), swallowing quality of life (SWAL-QOL), and National Institute of Health Stroke scale (NIHSS) among the three groups were compared before intervention, and at 4 and 8 weeks post-intervention. SPSS 27.0 software was used to analyze the data by one-way ANOVA, repeated measures ANOVA, Kruskal-Wallis H test, Mann-Whitney U test and Pearson correlation analysis. Results:(1) After 8 weeks of intervention, the effective improvement rates of feeding function were 75.00%(27/36) and 72.22%(26/36) in the stimulation group and rehabilitation group, respectively, which were both lower than that in the combined group (94.44%(34/36), both P<0.05). (2) The interaction effect between time and group was significant in MMASA scores among the three groups before and after intervention ( F=2.569, P<0.05). MMASA scores at 8 weeks post-intervention were higher than those at 4 weeks post-intervention and baseline in all groups (all P<0.05), and scores at 4 weeks post-intervention were also higher than those at baseline (all P<0.05). At 4 and 8 weeks post-intervention, MMASA scores in the combined group (85.64±11.26, 92.56±10.55) were higher than those in the stimulation group (73.52±12.65, 82.97±12.84) and rehabilitation group (72.47±11.38, 84.39±12.29) (all P<0.05). (3) The interaction effect between time and group was significant in SWAL-QOL total scores among the three groups before and after intervention ( F=18.561, P<0.05). SWAL-QOL total scores at 8 weeks post-intervention were higher than those at 4 weeks post-intervention and baseline in all groups ( P<0.05), and scores at 4 weeks post-intervention were also higher than those at baseline (all P<0.05). At 4 and 8 weeks post-intervention, SWAL-QOL total scores in the combined group (115.64±9.26, 135.68±9.55) were higher than those in the stimulation group (108.42±8.65, 113.75±8.84) and rehabilitation group (108.37±8.38, 114.39±9.29) (all P<0.05). (4) The interaction effect between time and group was significant in NIHSS scores among the three groups before and after intervention ( F=7.890, P<0.05). NIHSS scores at 8 weeks post-intervention were lower than those at 4 weeks post-intervention and baseline in all groups (all P<0.05), and scores at 4 weeks post-intervention were also lower than those at baseline (all P<0.05). At 4 and 8 weeks post-intervention, NIHSS scores in the combined group (8.36±1.35, 5.22±1.05) were lower than those in the stimulation group (11.65±2.11, 8.78±1.12) and rehabilitation group (11.32±2.03, 8.36±1.17) (all P<0.05). Conclusion:Multimodal and multisensory stimulation training can improve feeding-swallowing function and neurological impairment in stroke patients with dysphagia, with intervention effects superior to those of either approach used alone.

Objective:To investigate the effect of triply periodic minimal surfaces (TPMS) structure and ceramic volume fraction on the mechanical properties of polymer-infiltrated ceramic network (PICN) composite and reveal its strengthening and toughening mechanism.Methods:In this study, TPMS structures with gyroid (G), primitive (P), diamond (D), and ceramic volume fraction (40%, 55%, 70%, 85%) were designed. Porous zirconia scaffolds were prepared using stereolithography technology, and resin was infiltrated into the scaffolds through a vacuum. Then, the PICN composites were obtained after curing. The bending strength, elastic modulus and fracture toughness of PICN were tested using an electronic universal testing machine, with commercial PICN as the control group. The micromorphology of PICN was observed through stereomicroscope and scanning electron microscope. The cytocompatibility of PICN was verified by using cell counting kit, live/dead cell staining and phalloidin staining.Results:The bending strength values of PICN with different ceramic volume fractions ranged from 82.0 MPa to 376.0 MPa, and they gradually increased as the ceramic volume fraction rised. The elastic modulus values of PICN with different ceramic volume fractions ranged from 12.1 GPa to 56.1 GPa. The fracture toughness values of PICN with different ceramic volume fractions ranged from 1.7 MPa·m 1/2 to 6.5 MPa·m 1/2. The bending strength of 85G PICN reached 306.0 MPa, and it had the highest fracture toughness (6.5 MPa·m 1/2) and an appropriate elastic modulus between that of the control group and that of enamel. Under scanning electron microscopy, it could be observed that the cracks branch and deflect at the interface and eventually terminate within the resin phase. After co-culture with PICN, the survival rate of mouse fibroblasts exceeded 80%, indicating that PICN had no cytotoxicity. Conclusions:The PICN composite with TPMS structure can satisfy the mechanical properties and cytocompatibility of dental prosthesis.

Objective:To analyze the effects of low-molecular-weight heparin combined with insulin (LMWH+INS) and double filtration plasmapheresis (DFPP) on lipid profiles and clinical outcomes in patients with hypertriglyceridemic acute pancreatitis (HTG-AP) based on propensity score matching.Methods:The clinical data of 126 patients with HTG-AP from October 2022 to February 2024 in The Third Affiliated Hospital of Nanjing Medical University, Changzhou Traditional Chinese Medicine Hospital Affiliated to Nanjing Traditional Chinese Medicine University and Changzhou First People's Hospital were retrospectively included. Patients were divided into LMWH+INS group ( n=87) and DFPP group ( n=39) according to the treatment. Propensity score matching was applied at a 1∶1 ratio. The repeated measures analysis of variance was conducted to assess dynamic changes of blood lipids within the 5 days of admission between the LMWH+INS and DFPP groups after matching. Clinical symptoms and outcomes were compared between the two matched groups following matching. Results:29 patients were included in both LMWH+INS group and DFPP group after propensity score matching. No statistically significant differences were observed in triglycerides (TG), acute physiology and chronic health evaluation Ⅱ(APACHEⅡ) score, or bedside index for the severity of acute pancreatitis (BISAP) between the two groups (all P value >0.05), indicating comparability. Repeated measures analysis of variance revealed that TG and TC levels in the DFPP group were significantly lower than those in the LMWH+INS group at 2-5 days after admission [TG 2 d: (5.26±2.59) mmol/L vs (10.79±3.81) mmol/L, 3 d: (3.35±1.01) mmol/L vs (7.72±3.64) mmol/L, 4 d: (3.45±0.77) mmol/L vs (6.57±3.17) mmol/L, 5 d: (3.73±1.26) mmol/L vs (5.61±3.07) mmol/L; TC 2 d: (4.83±2.29) mmol/L vs (8.2±2.82) mmol/L, 3 d: (4.23±2.17) mmol/L vs (7.71±2.68) mmol/L, 4 d: (4.28±1.59) mmol/L vs (7.55±2.41) mmol/L, 5 d: (4.1±1.21) mmol/L vs (7.84±2.6) mmol/L], with a more rapid decrease. LDL levels in the LMWH+INS and DFPP groups showed similar trends, with significant decreases at 2 day after admission [(5.41±3.24) mmol/L vs (2.96±1.47) mmol/L, (4.99±3.51) mmol/L vs (2.47±1.53) mmol/L]. The differences mentioned above are all statistically significant (all P value <0.001). No significant changes were observed in HDL levels in either LMWH+INS and DFPP groups at 2-5 days after admission. After matching, the DFPP group had a significantly longer time of resuming feeding [3(2, 3) days vs 4(3, 6) days] and higher hospital cost [12113.87 (9055.31, 14401.84) yuan vs 28025.34 (25388.11, 36335.48) yuan] compared with the LMWH+INS group, with statistically significant differences. Conclusions:DFPP could reduce TG and TC levels more rapidly and effectively than LMWH combined with INS, but does not show an advantage in improving clinical outcomes and reducing hospitalization costs.

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 application value of high-flow nasal oxygen therapy combined with non-invasive positive pressure ventilation in very low birth weight infants after weaning from invasive mechanical ventilation.Methods From February 2022 to May 2024,80 cases of very low birth weight infants who were weaned from invasive mechanical ventilation in Second Affiliated Hospital of Wenzhou Medical University were selected and divided into single ventilation group and combined oxygen therapy group according to the random number table method,with 40 cases in each group.Single ventilation group was intervened with non-invasive positive pressure ventilation,while combined oxygen therapy group was intervened with high-flow nasal oxygen therapy combined with non-invasive positive pressure ventilation.The disappearance time of clinical symptoms,the score of neonatal behavioral neurological assessment(NBNA),vitamin D and blood gas indicators of two groups of premature infants were compared.And the degree of broncho pulmonary dysplasia(BPD)in premature infants was evaluated.Results The disappearance time of clinical symptoms,non-invasive positive pressure ventilation time and total oxygen requirement time of preterm infants in combined oxygen therapy group were significantly shorter than those in single ventilation group(P＜0.05).After 14 days of intervention,the NBNA scores,vitamin D,oxygenation index and blood oxygen saturation of premature infants in both groups were significantly higher than those before intervention in this group(P＜0.05).The NBNA score,vitamin D,oxygenation index and blood oxygen saturation of preterm infants in combined oxygen therapy group were significantly higher than those in single ventilation group(P＜0.05).The degree of BPD in combined oxygen therapy group was significantly milder than that in single ventilation group(x2=8.571,P=0.003).Conclusion After weaning from invasive mechanical ventilation in very low birth weight infants,high-flow nasal oxygen therapy combined with non-invasive positive pressure ventilation intervention can help reduce inflammatory responses and brain damage,improve blood gas indicators,and lower the degree of BPD.

Objective:To evaluate the impact of surgical margin status and pathological subtypes on the prognosis of patients with adenoid cystic carcinoma of the head and neck (ACCHN) who underwent postoperative radiotherapy.Methods:A retrospective analysis was conducted on 309 patients with initially treated, non-metastatic ACCHN who completed postoperative radiotherapy at Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine from January 2016 to December 2022. All patients underwent curative (non-palliative) surgery followed by postoperative radiotherapy, with a median dose of 66 Gy (range: 54-70 Gy). The Kaplan-Meier method was used to compare 5-year local recurrence-free survival (LRFS) between R0 (negative margin) and non-R0 resections in patients with initially resectable (T 1-T 4a stage) and initially unresectable (T 4b stage) disease. Univariate and multivariate Cox proportional hazards models were employed to analyze risk factors for local recurrence, with a focus on surgical margin status and pathological subtypes. Results:The median follow-up was 48 months. Of the 309 patients included in the study, 133 were males and 176 were females, with a median age of 51 years (range: 18-77 years). Primary tumors were located in the major salivary glands in 135 cases (including 42 in the parotid gland, 65 in the submandibular gland, and 28 in the sublingual gland) and in the minor salivary glands in 174 cases. The 5-year overall survival, locoregional recurrence-free survival, distant metastasis-free survival, and progression-free survival rates were 91.5%, 90.8%, 66.1%, and 63.9%, respectively. Non-R0 resection was achieved in 177 patients (57.3%). Among initially resectable patients ( n=253), the non-R0 resection rate was 49.0% ( n=124), with only 6 cases (2.4%) experiencing local recurrence (all non-R0 resections). In initially unresectable patients ( n=56), the non-R0 resection rate was as high as 95% ( n=53), with 13 cases (23%) experiencing local recurrence (2 cases in non-R0 resection and 1 case in R0 resection). For initially resectable patients, non-R0 resection significantly reduced the 5-year LRFS rate to 95.2%, compared to 100% in R0 resection patients ( P=0.014). However, multivariate analysis revealed that the solid pathological subtype was an independent risk factor for 5-year LRFS ( HR=7.40, 95% CI: 2.81-19.52, P<0.001), while the surgical margin status was not an independent factor. Conclusions:The combined strategy of surgery and postoperative radiotherapy provides high local control rates for ACCHN patients. Achieving R0 resection is crucial for initially resectable patients, while a comprehensive treatment strategy involving surgery and postoperative radiotherapy remains essential for initially unresectable patients. The solid pathological subtype is the most significant risk factor for local recurrence.

Objective To investigate the feasibility of non-ECG-gated scan using wide-body detector in left atrial computed tomo-graphy angiography(CTA)and to assess its value in evaluating left atrial appendage closure(LAAC)outcomes.Methods Patients who underwent LAAC and completed left atrial CTA were prospectively selected.Participants were randomly divided into groups A and B.In group A,the heart rate was measured using a finger clip oximeter before the examination,and the heart rate was set as the simula-ted heart rate.The simulated signal was generated by the CT equipment to complete the examination.In group B,the conventional ECG-gated scan was adopted.The residual leakage of left atrial appendage occluder,image quality,patient comfort and radiation dose of the two groups were compared,and statistical analysis was performed for these indicators.Results Both groups completed the evaluation of the endothelialization degree of the left atrial appendage occluder,and there was no significant difference in the objective image quality evaluation or subjective image score between the two groups(P＞0.05).The total scores of the physiological dimension,psy-chological dimension,social cultural dimension and environmental dimension of patients in group A were higher than those in group B(P＜0.001),and the volume CT dose index(CTDIvol)and dose length product(DLP)decreased by 25％and 25.36％respectively,with statistically significant differences(P＜0.001).Conclusion During the left atrial CTA examination,the wide-body detector with non-ECG-gated scan mode can provide good image quality for clinical use and observe the embolization of the left atrial appendage after LAAC surgery.At the same time,it can effectively reduce the radiation dose for patients and improve patient comfort dur-ing the examination,showing high clinical feasibility and appli-cation value.

Objective:To evaluate the safety and efficacy of accelerator-based boron neutron capture therapy (AB-BNCT) in the treatment of recurrent and refractory malignant tumors.Methods:The data of 14 patients admitted to Xiamen Humanity Hospital from September 2022 to April 2023 were prospectively collected, including 7 patients with primary brain malignancies and 7 patients with locally recurrent inoperable head and neck malignancies. All patients received intravenous infusion of boron drug (NBB-001, p-dihydroxyborylphe nylalanine, a patented freeze-dried formulation) at a total nominal dosage of 500 mg/kg (11 patients) or 750 mg/kg (3 patients), and were irradiated with neutrons (operating with NeuPex system). Adverse events after treatment were recorded and assessed. The primary efficacy endpoint was the 90 d objective response rate (ORR), while the secondary endpoints included progression-free survival (PFS) and complete response rate (CRR). Data were compiled and analyzed by SAS 9.4 software. The rate and 95% CI were calculated using Clopper-Pearson method. Results:The median dose delivered to 80% of the target volume (D 80%) was 16.80 GyE (range: 8.93-23.79 GyE). The most common adverse reactions were hyperamylasemia, alopecia, and hyperprolactinemia. Five patients experienced 8 cases of grade 3 or above adverse events, including 1 case of grade 4 acute kidney injury and 7 cases of grade 3 adverse events. All adverse events were recovered after observation or treatment. At 90 d after treatment, the ORR of all patients was 9/14 (64%, 95% CI: 35%-87%), disease control rate (DCR) was 10/14 (71%, 95% CI: 42%-92%), CRR was 2/14 (14%, 95% CI: 2%-42%); and the best overall response during the entire course included an ORR of 10/14 (71% ,95% CI: 42%-92%), DCR of 13/14 (93%, 95% CI: 66%-100%), and CRR of 3/14 (21% ,95% CI: 5%-51%). The 1-year survival rate for head and neck malignancies was 71.4%, and the 2-year survival rate was 42.8%. The 1-year survival rate for recurrent brain malignancies was 42.8%. Conclusion:AB-BNCT demonstrates favorable safety and promising efficacy in treating primary brain malignancies and recurrent/refractory head and neck malignancies, representing a potential therapeutic option.
