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.

[Purpose]To analyze the trends of incidence and mortality of thyroid cancer in the cancer registration areas of Nanning City from 2016 to 2020.[Methods]The incidence and mor-tality data of thyroid cancer from 2016 to 2020 were collected from the Nanning cancer registries,and the the quality of data was assessed.The crude incidence/mortality rates,the age-standar-dized incidence/mortality rates by Chinese standard population(ASIRC,ASMRC)and world stan-dard population(ASIRW,ASMRW),the cumulative incidence/mortality rates(0～74 years old),and the age-specific incidence/mortality rates were calculated.The Joinpoint regression model was used to estimate the trends of incidence and mortality,expressed as average annual percentage change(AAPC).[Results]From 2016 to 2020,a total of 2 291 new cases of thyroid cancer were reported in Nanning cancer registries.The crude incidence rate was 7.70/105 with the ASIRC of 7.23/105 and ASIRW of 6.22/105,the cumulative incidence rate was 0.59％.The incidence was higher in female than that in male,and higher in urban areas than that in rural areas.The incidence rate of thyroid cancer began to rise sharply from the 20 years old and reached peak in the age group of 50～54 years old.The incidence rate in female remained at a high level in the age group of 30～59 years old,which was higher than that in male.A total of 121 deaths of thyroid cancer were re-ported with a crude mortality rate of 0.41/105,ASMRC of 0.32/105,ASMRW of 0.31/105 and cu-mulative mortality rate of 0.03％.The mortality rate was higher in female than that in male.The age-specific mortality rate for thyroid cancer showed a fluctuant upward trend after the 40 years old and peaked in the age group of 75～79 years old.The crude incidence rate and ASIRC showed an upward trend in whole population(AAPC=21.11％,t=3.25,P＜0.05;AAPC=22.02％,t=3.39,P＜0.05),in male(AAPC=19.45％,t=4.35,P＜0.05;AAPC=19.81％,t=5.74,P＜0.05)and urban areas(AAPC=30.62％,t=7.13,P＜0.05;AAPC=32.38％,t=7.25,P＜0.05).The crude mortality rate and ASMRC in urban areas(AAPC=43.06％,t=7.73,P＜0.05;AAPC=47.63％,t=8.60,P＜0.05)also showed an increasing trend.[Conclusion]The crude incidence rate and ASIRC of thyroid cancer in cancer registration areas of Nanning City showed an overall upward trend from 2016 to 2020,except in rural areas;while the rising trends of the crude mortality rate and ASMRC were only observed in urban areas.

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.

Background Job burnout and depressive symptoms are prevalent among occupational populations, with a close relationship between them. Sleep quality, as a potential mediating factor, significantly affects the mental health of workers. Objective To explore the relationship between job burnout, sleep quality, and depressive symptoms, and determine whether sleep quality mediates the relationship between job burnout and depressive symptoms. Methods From April 25 to May 1, 2024, this study employed cluster sampling to conduct a questionnaire survey among individuals engaged in various occupations across five cities in the Ningxia Hui Autonomous Region. The questionnaires included socio-demographic information, as well as the Chinese Maslach Burnout Inventory (CMBI), the Pittsburgh Sleep Quality Index (PSQI), and the Patient Health Questionnaire-9 (PHQ-9) for assessing burnout, sleep quality, and depressive symptoms, respectively. Out of the 4106 questionnaires distributed, a total of 3837 questionnaires were valid, and the valid recovery rate was 93.45%. The distribution among demographic variables in burnout, sleep quality and depressive symptoms were statistically analyzed. A binary logistic regression model was used for multifactor correlation analysis; Pearson correlation was used to test the correlation between burnout, sleep quality, and depressed mood. Modelling and mediated effect path mapping were performed using Amos 24.0 software. Results The postive rate of occupational burnout in the workers was 97.49% (3741/3837), the positive rate of poor sleep quality was 66.77% (2526/3837), and the positive rate of depressive symptoms was 75.68% (2904/3837). There were statistically significant differences in depressive symptoms by ages, shift types, working years, marital status, smoking habits, drinking habits, and exercising frequency (P < 0.05). The logistic model indicated that working years, drinking habits, job burnout, and overall sleep quality were significant factors influencing the occurrence of depressive symptoms (P < 0.05). The correlation analysis revealed positive correlations between depressive symptom scores and job burnout scores (r=0.045, P < 0.01), between depressive symptom scores and sleep quality scores (r=0.480, P < 0.01), and between job burnout scores and sleep quality scores (r=0.054, P < 0.01). Furthermore, the indirect effect of job burnout on depressive symptoms through sleep quality was 0.100 (95%CI: 0.204, 0.252; P < 0.01). Conclusion Job burnout and sleep quality are significant factors associated with the occurrence of depressive symptoms among occupational populations, and sleep quality plays a partial mediating role in depressive symptoms associated with job burnout. This finding may provide a scientific basis for developing intervention strategies to control depressive symptoms among workers.

Objective:To analyze the influencing factors on the therapeutic effect of glucocorticoid impact in the treatment of active thyroid-related eye diseases.Methods:A total of 106 patients with thyroid-related eye disease admitted to Lishui People's Hospital from December 2020 to January 2024 were retrospectively selected, all of whom were treated with glucocorticoid impact therapy. According to the efficacy, they were divided into poor efficacy group (34 cases) and good efficacy group (72 cases), and relevant clinical data of the two groups were compared. Single factor and multiple factor Logistic regression were used to analyze the risk factors affecting the curative effect.Results:The proportion of smoking history in the poor efficacy group was higher than that in the good efficacy group:73.53% (25/34) vs. 29.17% (21/72), there was statistical difference ( χ2 = 18.50, P<0.01). The thyroid stimulating hormone (TSH) and lymphocyte (LYM) in the poor efficacy group were lower than those in the good efficacy group: (0.08 ± 0.02) mU/L vs. (0.10 ± 0.02) mU/L, 0.175 ± 0.028 vs. 0.192 ± 0.031;the free triiodothyronine (FT 3), free thyroxine (FT 4), tumor necrosis factor - α (TNF- α), interleukin (IL) -6, IL-8, neutrophil-to-lymphocyte ratio (NLR), degree of proptosis, and clinical activity score (CAS) were higher than those in the good efficacy group: (5.28 ± 1.21) pmol/L vs. (4.73 ± 1.03) pmol/L, (15.52 ± 2.35) pmol/L vs. (14.28 ± 2.31) pmol/L, (11.82 ± 2.11) ng/L vs. (10.05 ± 2.04) ng/L, (2.12 ± 0.21) ng/L vs. (1.96 ± 0.18) ng/L, (38.56 ± 4.35) ng/L vs. (35.46 ± 4.21) ng/L, 2.52 ± 0.41 vs. 1.67 ± 0.37, (17.42 ± 2.44) mm vs. (15.32 ± 2.27) mm, (4.34 ± 0.65) scores vs. (3.98 ± 0.63) scores, there were statistical differences ( P<0.05). Multiple Logistic regression analysis showed that smoking history, TSH, FT 3, FT 4, TNF-ɑ, IL-6, IL-8, LYM, NLR, exophthalmia and CAS score were all included in the regression equation, and they were all influential factors affecting the efficacy of glucocorticoid shock therapy for thyroid-related eye diseases ( P<0.05). Conclusions:In active thyroid-related eye disease patients receiving glucocorticoid impact therapy, the efficacy may be affected by many factors, and comprehensive intervention should be implemented according to the actual situation to further improve the efficacy.
