OBJECTIVE To evaluate the cost-effectiveness of the first-line treatment using the combination therapy of sugemalimab and chemotherapy （hereinafter referred to as the “combination therapy”） for advanced esophageal squamous cell carcinoma （ESCC） with high programmed death-ligand 1 （PD-L1） expression from the perspective of the Chinese healthcare system. METHODS A partitioned survival model was constructed based on data from the GEMSTONE-304 study. The model cycle was set at 3 weeks， with a study duration of 10 years and a discount rate of 5%. The primary output parameters of the model included total costs， quality-adjusted life year （QALY）， incremental costs， and incremental cost-effectiveness ratio （ICER）. Cost- utility analysis was employed to assess the economic feasibility of the combination therapy compared to chemotherapy alone. The robustness of the base case analysis results was evaluated through univariate sensitivity analysis， probabilistic sensitivity analysis， and scenario analysis. RESULTS The ICER of the combination therapy compared to chemotherapy alone was 288 430.35 yuan/QALY， significantly exceeding the willingness-to-pay （WTP） threshold of 173 354.52 yuan/QALY which was set at 1.94 times the per capita gross domestic product （GDP） in 2023. The price of sugemalimab was the primary factor influencing the ICER. When the WTP threshold was set at 1.94 times the per capita GDP （173 354.52 yuan/QALY）， the probability of the combination therapy being cost-effective compared to chemotherapy alone was 0. The combination therapy only became cost-effective compared to chemotherapy alone when the price of the drug dropped to 6 107.41 yuan per box （600 mg）. CONCLUSIONS From the perspective of the Chinese healthcare system， the combination therapy for first-line treatment of advanced ESCC with high PD-L1 expression is not cost-effective； the combination therapy is cost-effective when the price of sugemalimab decreas by 50.65%.

The transgender children and adolescents(TCAs)face serious social dilemmas in the process of gender identity and expression,which hinders this group from seeking reasonable and equal rights to survival and development.From the perspective of equal rights and the theoretical framework of social dilemma,by interviewing TCAs who seek help from medical social workers in a hospital's multi-disciplinary transgender clinic,this paper revealed that under the traditional system of"binary gender",TCAs lacked social inclusiveness and infrastructure,which led to the two major social dilemmas of"social traps"and"social barriers"encountered by this group in the process of gender expression and gender identity.Specifically,the social gender selection of TCAs often leads to collective irrational reactions and gender punishment,preventing their legal and effective medical services.To this end,the research team used critical methodology to construct a joint disciplinary diagnosis and treatment path for TCAs with the participation of medical social workers,as well as verified that the path has significant intervention effects in rationalizing the needs of TCAs and their families,alleviating their psychological pressure and social adaptation problems in the process of gender identity,fostering a diverse dialogue environment in their families,as well as enhancing their self-efficacy and social participation,to provide assistahce to the TCAs groups in social difficulties,assisting their rights and interests be included in the child-friendly indicator system,and improving the whole society's tolerance and understanding for TCAs group.

Background/Aims: Low educational attainment is a well-established risk factor for nonalcoholic fatty liver disease (NAFLD) in developed areas. However, the association between educational attainment and the risk of NAFLD is less clear in China. Methods: A cross-sectional study including over 200,000 Chinese adults across mainland China was conducted. Information on education level and lifestyle factors were obtained through standard questionnaires, while NAFLD and advanced fibrosis were diagnosed using validated formulas. Outcomes included the risk of NAFLD in the general population and high probability of fibrosis among patients with NAFLD. Logistic regression analysis was employed to estimate the risk of NAFLD and fibrosis across education levels. A causal mediation model was used to explore the potential mediators. Results: Comparing with those receiving primary school education, the multi-adjusted odds ratios (95% confidence intervals) for NAFLD were 1.28 (1.16 to 1.41) for men and 0.94 (0.89 to 0.99) for women with college education after accounting for body mass index. When considering waist circumference, the odds ratios (95% CIs) were 0.94 (0.86 to 1.04) for men and 0.88 (0.80 to 0.97) for women, respectively. The proportions mediated by general and central obesity were 51.00% and 68.04% for men, while for women the proportions were 48.58% and 32.58%, respectively. Furthermore, NAFLD patients with lower educational attainment showed an incremental increased risk of advanced fibrosis in both genders. Conclusions In China, a low education level was associated with a higher risk of prevalent NAFLD in women, as well as high probability of fibrosis in both genders.

Objective: To investigate the trends in incidence of viral hepatitis in Yuxi City, Yunnan Province from 2004 to 2022, so as to provide insights into the management of viral hepatitis. Methods: Data of viral hepatitis cases in Yuxi City from 2004 to 2022 were retrieved from the China Disease Prevention and Control Information System. The temporal, human and spatial distribution of viral hepatitis cases were analyzed using a descriptive epidemiological method, and the trends in incidence of viral hepatitis were evaluated in Yuxi City from 2004 to 2022 using annual percent change (APC) and average APC (AAPC). Results: A total of 37 430 viral hepatitis cases were reported in Yuxi City from 2004 to 2022, with an average annual incidence rate of 91.27/105, and the incidence showed a tendency towards a rise (AAPC=12.686, P<0.05). There were 29 229 cases with hepatitis B, 5 796 cases with hepatitis C, 1 451 cases with hepatitis A, 520 cases with hepatitis E and 434 cases with unclassified hepatitis reported in Yuxi City, with average annual incidence rates of 71.27/105, 14.13/105, 3.54/105, 1.27/105 and 1.06/105, respectively. The average annual incidence rates of viral hepatitis were 98.24/105 and 78.94/105 among men and women, which both appeared a tendency towards a rise (AAPC=12.415% and 12.581%, both P<0.05). The highest average annual incidence of viral hepatitis was seen among residents at age of 25 to 29 years (139.89/105), with the lowest seen among residents at ages of 0 to 4 years (11.38/105), and the average annual incidence of viral hepatitis appeared a tendency towards a rise with age (P<0.05). The highest average annual incidence of viral hepatitis was seen in Huaning County (234.24/105), with the lowest seen in Chengjiang City (26.11/105), and the average annual incidence appeared a tendency towards a rise in Xinping County from 2004 to 2022 (AAPC=21.451%, P<0.05). Conclusions The reported incidence of viral hepatitis appeared a tendency towards a rise in Yuxi City from 2004 to 2022, with hepatitis B as the main type. High incidence was seen among men and adolescents. The viral hepatitis control strategy requires to be adjusted with adaptations to high-incidence hepatitis subgroups, residents and regions.

Objective:To study the correlation between serum uric acid (SUA) and vascular calcification in middle-aged and elderly men.Methods:Using the Yiduyun electronic medical record retrieval system, a cross-sectional study was conducted on the clinical data of 2 786 male patients aged ≥40 years who underwent lung CT examinations in Dalian Central Hospital, Dalian University of Technology from January 2010 to October 2022. According to the degree of pulmonary CT vascular calcification, they were divided into vascular calcification group (1 296 cases)and non vascular calcification group (1 490 cases). The clinical data were collected and the correlation between SUA and vascular calcification were analyzed.Results:The levels os SUA in the vascular calcification group was higher than that in the non vascular calcification group: 311.50(270.25, 359.00) μmol/L vs. 284.00(251.00, 318.00) μmol/L, there was statistical difference ( F = 14.16, P<0.01). The constituent ratio of hyperuricemia in vascular calcification group was higher than that in non vascular calcification group : 25.62%(332/1 296) vs. 11.68%(174/1 490), there was statistical difference ( χ2 = 20.15, P<0.01). Spearman correlation analysis found a positive correlation between SUA level and vascular calcification in middle-aged and elderly men ( r = 0.489, P<0.01). Binary Logistic regression analysis results showed that SUA, body mass index (BMI), diastolic blood pressure(DBP), fasting plasma glucose(FPG) were positively correlated with vascular calcification ( P<0.01); after adjusting the influence of BMI, DBP and FPG on male vascular calcification, SUA was still a risk factor for vascular calcification. Conclusions:In the middle-aged and elderly male population, with the increase of blood uric acid, vascular calcification increase, and the elevated blood uric acid level is an independent risk factor for vascular calcification.

Objective:To observe the changes of skeletal muscle indexes in elderly patients with type 2 diabetes complicated with sarcopenia treated with sitagliptin and acarbose.Methods:A total of 60 patients over 60 years old with type 2 diabetes complicated with sarcopenia in Dalian Municipal Central Hospital from January 2019 to January 2020 were selected and divided into two groups by random number table method.One group received sitagliptin and metformin,and the other group received acarbose and metformin. The changes of skeletal muscle indexes, glucagon-like peptides-1 (GLP-1), insulin resistance index (HOMA-IR) and inflammatory indexes were compared between the two groups at baseline and 36 weeks after treatment.Results:After treatment, the skeletal muscle index (SMI) of sitagliptin group was increased (5.94 ± 1.52 vs. 5.99 ± 1.52), and the difference was statistically significant ( P<0.05). Muscle strength and SMI decreased in acarbosse group (18.75 ± 4.64 vs. 17.72 ± 4.44, 6.09 ± 1.74 vs. 6.00 ± 1.71), with statistical significance ( P<0.05). GLP-1 increased in sitagliptin group, 0 min: (10.65 ± 1.68) pmol/L vs. (12.41 ± 1.88) pmol/L; 60 min: (22.79 ± 2.85) pmol/L vs. (25.51 ± 2.79) pmol/L; 120 min: (24.26 ± 2.94) pmol/L vs. (29.49 ± 2.91) pmol/L; 180 min: (11.68 ± 1.84) pmol/L vs. (12.88 ± 1.83) pmol/L. There were significant differences ( P<0.05). HOMA-IR and CRP decreased: 4.73 ± 3.04 vs. 3.16 ± 2.41, (2.39 ± 0.50) mg/L vs. (2.33 ± 0.43) mg/L, and the differences were statistically significant ( P<0.05).

Objective: To investigate the relationship between neck circumference and metabolic syndrome (MS) in ≥ 40 years old community residents. Methods: A total of 5 017 Dalian community residents who participated in "the risk evaluation of cancers in Chinese diabetic individuals: a longitudinal study" from July to December 2014 were selected, with 1 256 male cases and 3 761 female cases, aged ≥ 40 years old. The basic information was selected by questionnaire. The neck circumference, waist circumference (WC), body height, weight, systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting plasma glucose (FPG), 2 h-postprandial plasma glucose (2 h PG), glycosylated hemoglobin (HbA₁c) and blood fat were measured; the body mass index (BMI) was calculated. Results: The age, neck circumference, WC, FPG, 2 h PG, SBP, DBP, incidence of obesity, incidence of hypertension and incidence of type 2 diabetes mellitus in male were significantly higher than those in female: (63.5 ± 8.4) years vs. (60.8 ± 8.0) years, (38.6 ± 3.0) cm vs. (34.4 ± 2.6) cm, (92.3 ± 9.1) cm vs. (87.3 ± 9.6) cm, 5.59 (5.20, 6.42) mmol/L vs. 5.43 (5.09, 5.99) mmol/L, 7.67 (6.06, 11.08) mmol/L vs. 7.20 (5.97, 9.64) mmol/L, (135.3 ± 18.8) mmHg (1 mmHg = 0.133 kPa) vs. (129.8 ± 19.5) mmHg, (79.8 ± 10.7) mmHg vs. (74.8 ± 10.0) mmHg, 53.0% (666/1 256) vs. 48.9% (1 841/3 761), 49.9% (627/1 256) vs. 40.6% (1 528/3 761) and 29.8% (374/1 256) vs. 22.5% (846/3 761); the total cholesterol, triacylglycerol, high density lipoprotein cholesterol, low density lipoprotein cholesterol and incidence of central obesity in male were significantly lower than those in female: (5.04 ± 0.94) mmol/L vs. (5.58 ± 1.03) mmol/L, 1.35 (0.97, 1.95) mmol/L vs. 1.45 (1.06, 2.04) mmol/L, (1.18 ± 0.27) mmol/L vs. (1.32 ± 0.29) mmol/L, (2.99 ± 0.78) mmol/L vs. (3.27 ± 0.85) mmol/L and 63.7% (800/1 256) vs. 79.7% (2 998/3 761), and there were statistical differences (P<0.01 or <0.05). There were no statistical differences in BMI, HbA₁c and incidence of MS between male and female (P>0.05). After adjustment for age, smoking, drinking, menopausal status (female), BMI and WC, Logistic regression analysis result showed that increased neck circumference in male increased the risk of type 2 diabetes mellitus (OR = 1.075, 95% CI 1.012 to 1.142, P = 0.019); increased neck circumference in female increased the risks of type 2 diabetes mellitus (OR = 1.143, 95% CI 1.096 to 1.192, P = 0.000), hypertension (OR = 1.112, 95% CI 1.071 to 1.156, P = 0.000), hypertriacylglyceremia (OR = 1.099, 95% CI 1.060 to 1.139, P = 0.000), low HDL-C (OR = 1.104, 95% CI 1.064 to 1.144, P = 0.000) and MS (OR = 1.167, 95% CI 1.120 to 1.217, P = 0.000). Taking neck circumference as detection variable and MS as outcome variable, the receiver operating characteristic curve was analyzed. In male, the area under curve was 0.733, the optimal cut-off value of neck circumference was 37.9 cm, with a sensitivity of 77.9%, and a specificity of 55.9%. In female, the area under curve was 0.720, the optimal cut-off value of neck circumference 33.3 cm, with a sensitivity of 76.7%, and a specificity of 56.0%. Conclusions Neck circumference is associated with MS in ≥ 40 years old community residents. Male neck circumference >37.9 cm and female neck circumference>33.3 cm are the optimal cut-off value for forecasting MS.
