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 explore the risk factors for ischemic stroke in patients with atrial fibrilla-tion(AF)and construct a prediction model.Methods A retrospective study was conducted on 253 AF patients treated at our hospital from January 2021 to December 2024.They were randomly divided into a modeling group(n=177)and a validation group(n=76)in a 7∶3 ratio.The model-ing group was further divided into a simple AF subgroup(96 cases)and a stroke subgroup(81 cases)based on the occurrence of ischemic stroke.Clinical data were collected,including low-density lipoprotein cholesterol,red cell distribution width(RDW),D-dimer,fibrinogen,N-terminal pro-B-type natriuretic peptide(NT-proBNP),high-sensitivity cardiac troponin I(hs-cTnI),etc.Univariate and multivariate logistic regression analyses were performed to identify risk factors for ischemic stroke,and a nomogram model was constructed.The predictive performance of the model was evaluated using ROC curve analysis,calibration curve analysis,and decision curve analysis(DCA).Results Multivariate logistic regression analysis indicated that left atrial diameter(OR=1.205,95％CI:1.046-1.388,P=0.010),RDW(OR=1.605,95％CI:1.138-2.263,P=0.007),D-dimer(OR=2.633,95％CI:1.229-5.640,P=0.013),fibrinogen(OR=3.053,95％CI:1.312-7.108,P=0.010),NT-proBNP(OR=1.005,95％CI:1.003-1.007,P=0.001),and hs-cTnI(OR=1.129,95％CI:1.046-1.218,P=0.002)were independent risk factors for ischemic stroke in AF patients.ROC curve analysis showed an AUC value of 0.926(95％CI:0.885-0.967)for the modeling group and 0.912(95％CI:0.847-0.978)for the validation group.H-L test showed Chi-square=8.005,P=0.433 for the modeling group and Chi-square=2.590,P=0.957 for the validation group.DC A demonstrated high practical value for the model.Conclusion The nomo-gram model constructed in the study has good predictive performance and clinical utility.

Objective To develop and apply a self-management question prompt list for ovarian cancer postoperative patients to meet patients'information needs and promote the level of self-management.Methods The draft of the list was prepared through literature review and semi-structured interviews.From September to November 2023,the Delphi method was adopted to conduct 2 rounds of correspondence,and the list items were revised and improved based on expert opinions,and the final list was confirmed.From December 2023 to February 2024,a total of 28 ovarian cancer postoperative patients in a tertiary A hospital in Liaoning Province were conveniently selected as application subjects.The changes in patients'self-care ability before and after application were compared,and the evaluation of 28 medical staff on the implementation effect of the checklist was investigated.Results The effective questionnaire recovery rates were 95％and 100％;the expert authority coefficients were 0.92 and 0.90;the Kendall harmony coefficients were 0.284 and 0.302,respectively,all P＜0.001.The final list included 5 dimensions,including 11 items of disease and treatment,13 items of postoperative and daily care,9 items of physical symptom management,7 items of psychosocial support,and 5 items of prognosis information,with a total of 45 questions.The preliminary application results showed that there was a statistically significant difference in the scores of patients'self-care ability before and after the application of the checklist(t=14.92,P＜0.001),and the satisfaction rate of the evaluation items of the implementation effect of the checklist was 92.86％～100％.Conclusion The contents of the list items are comprehensive,targeted and practical,which can mobilize patients'subjective initiative of seeking information and improve self-management ability.

Objective:To explore the training method for personalized eyebrow shape design before eyebrow transplantation surgery and to evaluate its effectiveness.Methods:Thirty physicians with similar foundational knowledge in facial aesthetic design and equivalent educational backgrounds were prospectively selected from the Second Hospital of Lanzhou University and Beijing Biliansheng Medical Beauty Clinic from January to December 2023. All the physicians were right-handed. Based on prior experience in eyebrow transplantation surgery, they were divided into two groups: an observation group [ n=20; 10 males, 10 females; aged (27.8±3.9) years] without experience in personalized eyebrow transplantation surgery, and a control group [ n=10; 5 males, 5 females; aged (29.6±4.0) years] with at least 2 years of experience in personalized eyebrow transplantation surgery. All the physicians received 2 hours of theoretical instruction on personalized eyebrow shape design and 8 hours of simulated operation training. Differences in personalized eyebrow design scores between the two groups were compared before and after training. After the assessment, physicians in the observation group performed eyebrow shape design on 20 eyebrow transplantation patients with randomly assigned face shapes, and patient satisfaction was evaluated. Results:Before training, personalized eyebrow design scores were 1.16±0.29 for the observation group and 3.75±0.22 for the control group, showing a statistically significant difference ( P<0.001). After operation training, the scores were 4.51±0.11 for the observation group and 4.89±0.08 for the control group, with no statistically significant difference ( P>0.05). The difference between pre- and post-training scores within the observation group was statistically significant ( P<0.05). Physicians in the observation group designed eyebrow shapes for male and female patients with various face shapes. Immediately after surgery, 80% (16/20) of patients were very satisfied, and 20% (4/20) were satisfied. Conclusion:After training of combined theoretical lectures, simulated practice, and hands-on patient design, physicians in the observation group demonstrate improved ability in personalized eyebrow shape design and achieve high patient satisfaction.

Objective:To explore the factors influencing the recovery of swallowing function after a brainstem hemorrhage and to construct a prediction model.Methods:Clinical data on 134 persons with dysphagia after a brainstem hemorrhage were collected retrospectively. According to their swallowing ability at discharge, the patients were divided into a swallowing recovery group and a non-recovery group. Univariate correlation analysis and multivariate logistic regression analysis were used to explore the independent factors influencing the recovery of swallowing function and to construct a prediction nomogram. The receiver operating characteristics (ROC) curves were evaluated to analyze the nomogram′s predictive value and those of the relevant influencing factors.Results:Sixty-two of the patients (46%) had recovered their swallowing function at discharge, while 72 (54%) had not. Univariate correlation analysis showed that there had been significant differences in tracheal intubation, NIHSS score, FOIS score, Barthel index and Glasgow coma scale (GCS )score between the two groups, on average. The multivariate logistic regressions showed that a low NIHSS score, a high FOIS score and a high GCS score were independent predictors of swallowing function recovery, so they were used in the prediction model. ROC curve analysis showed that the area under the curve (AUC) of the prediction model was 0.953 (95% CI: 0.902~0.982) with a sensitivity of 87% and a specificity of 93%. The model′s predictions were thus better than using an NIHSS score, GCS score or FOIS score alone. Conclusions:NIHSS score, GCS score and FOIS score can independently predict the recovery of swallowing function after a brainstem hemorrhage. A prediction model constructed using all three has good predictive power.

Objective:To explore the impact of age on the genetic variant spectrum and prognosis of patients with previously untreated Diffuse large B-cell lymphoma (DLBCL).Methods:A retrospective analysis was conducted on the clinical data and follow-up information of 254 previously untreated DLBCL patients from 14 hospitals in the Jiangsu Cooperative Lymphoma Group (JCLG) enrolled from July 2018 and July 2023. Following extraction of DNA from tumor tissue samples, next-generation sequencing (NGS) technique was employed to analyze the genetic variant spectrum of the DLBCL patients, with an evaluation of the relationship between age and genetic variants as well as prognosis. This study was approved by the Medical Ethics Committee of the Affiliated Hospital of Nantong University (Ethics No.: 2023-K048-01).Results:The median age of the 254 DLBCL patients was 62 years old, with 55% of patients aged 60 years or above. Clinical evaluation showed that younger (< 60 years) patients had higher complete response (CR) (70% vs. 59%), and objective response rate (ORR) (88% vs. 79%) than older patients, though the difference between the two groups was not statistically. Survival analysis indicated that both the five-year overall survival (OS) (82.7% vs. 71.7%, P=0.006) and progression-free survival (PFS) (70.6% vs. 50.2%, P<0.05) rates were significantly higher in younger patients. NGS showed that 99.6% of the patients harbored genetic variants, with PIM1, KMT2D, TP53, MYD88, and CD79B being the most common genes. Age significantly affected the variant frequency of certain genes, with MYC variants serving an adverse prognostic factor for OS in younger patients ( P=0.001), while TP53 ( P=0.024) and BCL2 ( P=0.002) variants significantly impacted OS in older patients. Prognostic analysis identified age ≥ 60 years ( HR=3.439, 95% CI=1.318~9.874), presence of B symptoms ( HR = 2.871, 95% CI=1.133~7.307), and elevated lactate dehydrogenase ( HR=3.528, 95% CI=1.231~10.66) as independent adverse prognostic factors. Conclusion:Age, genetic variants, and clinical factors may significantly affect the prognosis of the DLBCL patients. Younger patients have better survival compared to older patients. Variants of the MYC, BCL2, and TP53 genes are closely associated with poor prognosis.

The theory of "origin essence-origin qi-origin spirit" is rooted in the theory of "essence-qi-spirit", which explains that origin essence, origin qi, origin spirit as the important material foundation, energy power and regulation center in the process of growth and development of the organism, are mutual and complementary to each other, and operate orderly under the guidance of the ministerial fire. Tumor is essentially an abnormal disorder of the growth and development process of the organism, and its occurrence and development are directly related to the mutation of origin essence and the alienation of ministerial fire, and closely related to the attenuation of origin qi, the departure of ministerial fire, and the inefficiency of origin spirit, and the delusional movement of ministerial fire. Based on the theory of "origin essence-origin qi-origin spirit", the tumor can be treated in the clinic by regulating the ministerial fire suppressing origin essence to inhibit the tumor development, strengthening the spleen and benefiting the qi to slow down the attenuation of origin qi, and nourishing the heart and cultivating the mind to stabilize the power of origin spirit in order to further improve the understanding of TCM on the etiology of tumors, and at the same time, to provide a new direction and ideas for the clinical treatment of tumors.

Resistance to poly adenosine diphosphate(ADP)-ribose polymerase inhibitor(PARPi)presents a considerable obstacle in the treatment of ovarian cancer.F-box and tryptophan-aspartic(WD)repeat domain containing 11(FBXW11)modulates the ubiquitination of growth-and invasion-related factors in lung cancer,colorectal cancer,and osteosarcoma.The function of FBXW11 in PARPi therapy is still ambiguous.In this study,RNA sequencing(RNA-seq)showed that FBXW11 expression was raised in ovarian cancer cells that had been treated with PARPi.FBXW11 was abnormally expressed at low levels in high-grade serous ovarian cancer(HGSOC)tissues,and low levels of FBXW11 were associated with shorter overall survival(OS)and progression-free survival(PFS)in HGSOC patients.Overexpressing FBXW11 made ovarian cancer more sensitive to PARPi,while knocking down FBXW11 made it less sensitive.The four-dimensional(4D)label-free quantitative proteomic analysis revealed that FBXW11 targeted S100 calcium binding protein A11(S100A11)and promoted its degradation through ubiquiti-nation.The increased degradation of S100A11 led to less efficient DNA damage repair,which in turn contributed to increased PARPi-induced DNA damage.The role of FBXW11 in promoting PARPi sensitivity was also confirmed in xenograft mouse models.In summary,our study confirms that FBXW11 promotes the susceptibility of ovarian cancer cells to PARPi via affecting S10OA11-mediated DNA damage repair.

Mechanical pain is one of the most common causes of clinical pain, but there remains a lack of effective treatment for debilitating mechanical and chronic forms of neuropathic pain. Recently, neurotoxin GsMTx4, a selective mechanosensitive (MS) channel inhibitor, has been found to be effective, while the underlying mechanism remains elusive. Here, with multiple rodent pain models, we demonstrated that a GsMTx4-based 17-residue peptide, which we call P10581, was able to reduce mechanical hyperalgesia and neuropathic pain. The analgesic effects of P10581 can be as strong as morphine but is not toxic in animal models. The anti-hyperalgesic effect of the peptide was resistant to naloxone (an μ-opioid receptor antagonist) and showed no side effects of morphine, including tolerance, motor impairment, and conditioned place preference. Pharmacological inhibition of TRPV4 by P10581 in a heterogeneous expression system, combined with the use of Trpv4 knockout mice indicates that TRPV4 channels may act as the potential target for the analgesic effect of P10581. Our study identified a potential drug for curing mechanical pain and exposed its mechanism.
