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%.

Background::There is a need for effective and safe therapies for psoriasis that provide sustained benefits. The aim of this study was to assess the efficacy and safety of tildrakizumab, an anti-interleukin-23p19 monoclonal antibody, for treating moderate-to-severe plaque psoriasis in Chinese patients.Methods::In this multi-center, double-blind, phase III trial, patients with moderate-to-severe plaque psoriasis were enrolled and randomly assigned (1:1) to receive subcutaneous tildrakizumab 100 mg or placebo at weeks 0 and 4. Patients initially assigned to placebo were switched to receive tildrakizumab at weeks 12, 16, and every 12 weeks thereafter. Patients in the tildrakizumab group continued with tildrakizumab at week 16, and every 12 weeks until week 52. The primary endpoint was the Psoriasis Area and Severity Index (PASI 75) response rate at week 12.Results::At week 12, tildrakizumab demonstrated significantly higher PASI 75 response rates (66.4% [73/110] vs. 12.7% [14/110]; difference, 51.4% [95% confidence interval (CI), 40.72, 62.13]; P <0.001) and Physician’s Global Assessment (60.9% [67/110] vs. 10.0% [11/110]; difference, 49.1% [95% CI, 38.64, 59.62]; P <0.001) compared to placebo. PASI 75 response continued to improve over time in both tildrakizumab and placebo-switching to tildrakizumab groups, reaching maximal efficacy after 28 weeks (86.8% [92/106] vs. 82.4% [89/108]) and maintained up to 52 weeks (91.3% [95/104] vs. 87.4% [90/103]). Most treatment-emergent adverse events were mild and not related to tildrakizumab. Conclusion::Tildrakizumab demonstrated durable efficacy through week 52 and was well tolerated in Chinese patients with moderate-to-severe plaque psoriasis.Trial registration::ClinicalTrials.gov, NCT05108766.

Objective:The aim of noise quality management for ICU patients was to explore the clinical feasibility of noise quality management.Methods:A randomized controlled trial method and convenient sampling method were used to select 240 patients treated in the ICU of Shanghai Fengxian District Central Hospital from April 2021 to March 2023 as the study objects. According to the time of admission, 120 patients admitted from April 2021 to March 2022 were divided into the control group. A total of 120 patients admitted to hospital from April 2022 to March 2023 were included in the intervention group. The control group was given routine care, and noise quality management was implemented in the intervention group on the basis of routine care. The noise decibel value, sleep quality, incidence of delirium and patient satisfaction of the two groups were compared.Results:In the intervention group, there were 69 males and 51 females, aged (56.08 ± 5.74) years old. The control group included 68 males and 52 females, aged (56.11 ± 5.72) years old. The decibels of day and night in ICU of the intervention group were (42.62 ± 1.33) and (38.72 ± 1.28) dB, which were lower than those of the control group (67.49 ± 2.36) and (59.65 ± 2.37) dB, with statistically significant differences ( t=100.57, 85.12, both P<0.05). Total score of sleep quality of patients in the intervention group (78.40 ± 5.86) was higher than that of the control group (60.49 ± 6.25), with statistically significant differences ( t=24.32, P<0.05). The incidence of delirium in the intervention group 12.50%(15/120), was lower than that in the control group 26.67%(32/120) with a statistically significant difference ( χ2=7.65, P<0.05). Satisfaction of patients in the intervention group 97.50%(117/120) was higher than that in the control group 90.00%(108/120), with a statistically significant difference ( χ2=5.76, P<0.05). Conclusions:The application of noise quality management for ICU patients is conducive to improving the overall environment of the ward, improving the sleep quality of patients, reducing the occurrence of patients′ delirium and improving patient satisfaction.

Objective:The transjugular or transfemoral approach is used as a common method for hepatic venous pressure gradient (HVPG) measurement in current practice. This study aims to confirm the safety and effectiveness of measuring HVPG via the forearm venous approach.Methods:Prospective recruitment was conducted for patients with cirrhosis who underwent HVPG measurement via the forearm venous approach at six hospitals in China and Japan from September 2020 to December 2020. Patients' clinical baseline information and HVPG measurement data were collected. The right median cubital vein or basilic vein approach for all enrolled patients was selected. The HVPG standard process was used to measure pressure. Research data were analyzed using SPSS 22.0 statistical software. Quantitative data were used to represent medians (interquartile ranges), while qualitative data were used to represent frequency and rates. The correlation between two sets of data was analyzed using Pearson correlation analysis.Results:A total of 43 cases were enrolled in this study. Of these, 41 (95.3%) successfully underwent HVPG measurement via the forearm venous approach. None of the patients had any serious complications. The median operation time for HVPG detection via forearm vein was 18.0 minutes (12.3~38.8 minutes). This study confirmed that HVPG was positively closely related to Child-Pugh score ( r = 0.47, P = 0.002), albumin-bilirubin score ( r = 0.37, P = 0.001), Lok index ( r = 0.36, P = 0.02), liver stiffness ( r = 0.58, P = 0.01), and spleen stiffness ( r = 0.77, P = 0.01), while negatively correlated with albumin ( r = -0.42, P = 0.006). Conclusion:The results of this multi-centre retrospective study suggest that HVPG measurement via the forearm venous approach is safe and feasible.

Objective:To analyze the results of the practice test and formal test of the annual professional proficiency test for residents in 2022, to investigate related influencing factors and the effectiveness of the practice test, and to propose the measures for improving the results of the annual professional proficiency test.Methods:The scores of the annual professional proficiency test were analyzed for 202 residents who participated in the test in 2022, and the data on sex, education background, type of personnel, whether they passed the medical licensing examination, and practice test scores were analyzed to investigate related influencing factors. SPSS 23.0 and GraphPad Prism 8 were used for the chi-square test, the t-test, the one-way of variance, and the Fisher's exact test. A multiple linear regression analysis was used to identify influencing factors, and a Pearson correlation analysis was also performed. Results:The scores of the annual professional proficiency test for 202 residents were normally distributed with the highest number of the residents with a score of 90-99 points and the lowest number of the residents with a score of <70 points. The residents who passed the medical licensing examination had a significantly higher score of the annual professional proficiency test than those who failed the examination ( t=2.87, P=0.005), and the residents who passed the three practice tests had a significantly higher score of the annual professional proficiency test than those who failed the practice tests ( P<0.05). The score of the second practice test, the score of the third practice test, and the passing of medical licensing examination were independent influencing factors for the score of annual professional proficiency test ( R2=0.236, R2=0.201, F=6.60, P<0.05). The correlation analysis showed that the scores of the three practice tests were positively correlated with the final score ( r=0.189, 0.373, and 0.311, P<0.05). Conclusions:Improving the passing rate of medical licensing examination and strengthening pre-examination practice tests can help to improve the score of annual professional proficiency test. At the same time, it is necessary to improve the quality of training through the measures such as strengthening the homogenization management of different types of students, improving the attention and enthusiasm of all levels, and accelerating the construction of question banks.

Objective:To investigate the application effect of the comprehensive innovative teaching model with "3D printed model combined with visual surgical simulation" as the core in the clinical teaching of extremity bone defects.Methods:The physicians who participated in the clinical management of patients with extremity bone defects in Department of Orthopedics, Peking University Third Hospital, from March 2019 to December 2021 were selected as subjects and were divided into standardized training group with 52 physicians and refresher physician group with 58 physicians. Teaching and training was performed for the special disease of extremity bone defects, including basic knowledge teaching, dressing change for infected wounds, multidisciplinary discussion, digital surgical simulation, and practical surgical operation. The assessment indices for teaching quality included the assessment of theoretical knowledge and clinical skills, the objective evaluation of the clinical ability of patient management, and an investigation of the degree of satisfaction. SPSS 22.0 was used for the t-test and the chi-square test. Results:After training, both groups had significant increases in the assessment scores of theoretical knowledge [(32.4±6.7）and (42.2±3.8)] and clinical practice skills [(19.6±2.0), (20.8±2.2), (20.5±2.5), (21.5±2.3)]( P<0.05). After training, the standardized training group had significant increases in the scores of six objective evaluation indicators [(8.3±0.8) vs. (6.9±1.1), (7.4±0.7) vs. (6.3±1.5), (7.2±1.3) vs. (5.0±1.4), (7.9±1.2) vs. (4.0±1.5), (8.4±0.8) vs. (6.4±1.6), (40.3±2.6) vs. (28.6±2.4)]( P<0.01), while the refresher physician group had significant improvements in four aspects, i.e., the understanding of extremity bone defects [(8.1±0.9) vs. (7.2±1.1)], the self-confidence in facing complex extremity bone defects [(8.1±1.2) vs. (6.6±0.9)], spatial thinking ability in repair surgery for bone defects [(8.6±0.8) vs. (7.3±0.9)], and overall clinical performance in actual management of patients with bone defects [(41.4±2.3) vs. (37.3±1.8)] ( P<0.01). The satisfaction score for this comprehensive innovative teaching model was (95.3±3.2) points in the standardized training group and (94.8±2.8) points in the refresher physician group. Conclusions:The comprehensive innovative teaching model with "3D printed model combined with visual surgical simulation" as the core can significantly improve the basic knowledge and clinical skills of physicians in a short period of time and meet the needs for learning surgical techniques and advanced diagnosis and treatment concepts among refresher physicians.

Objective To evaluate the safety,tolerability and clinical effects of magnetic resonance imaging(MRI)-guided personalized repetitive transcranial magnetic stimulation(rTMS)in adolescents with depression.Methods Select 80 patients with depression who visited Hangzhou Seventh People's Hospital from February to December 2023 as the research subjects.According to the random number table method,it is divided into precision localization group and routine group.The precision localization group targeted the left dorsolateral prefrontal cortex(DLPFC)as the stimulus target based on MRI,while the conventional group used the traditional"5cm"to locate the left DLPFC.Treatment of all particioants was administered five times,continues two weeks,per week for a total of 10 sessions(resting motor threshold with 90％,stimulation frequency with 10Hz,40 pulses per session,inter-train interval 10 seconds,60 trains per day,totaling 2400 pulses).Changes of Hamilton depression rating scale 17(HAMD-17)and Hamilton anxiety rating scale(HAMA)were evaluated,with treatment response defined as ≥50％reduction in HAMD-17 or HAMA scores.Adverse events were collected and recorded during daily interviews.Results There were no significant differences in baseline HAMD-17 and HAMA scores between precision localization group and routine group(P＞0.05).However,after 2 weeks of treatment,there were significant differences in HAMD-17 and HAMA scores(t=3.940,P=0.027;Z=-2.060,P=0.039).The effective rates for depression and anxiety symptoms in precision localization group was 81.48％and 51.85％respectively,and 43.33％and 23.33％respectively in routine group,with statistically significant differences between two groups(x2=8.730,P=0.003;x2=4.970,P=0.026).No serious adverse events occurred in two groups.Conclusion For adolescents with depression,rTMS guided by MRI for individualized precise localization is an effective and safe treatment option,rapidly alleviats depressive and anxiety symptoms.

BACKGROUND: Significant brain volume deviation is an essential phenotype in children with neurodevelopmental delay (NDD), but its genetic basis has not been fully characterized. This study attempted to analyze the genetic factors associated with significant whole-brain deviation volume (WBDV). METHODS: We established a reference curve based on 4222 subjects ranging in age from the first postnatal day to 18 years. We recruited only NDD patients without acquired etiologies or positive genetic results. Cranial magnetic resonance imaging (MRI) and clinical exome sequencing (2742 genes) data were acquired. A genetic burden test was performed, and the results were compared between patients with and without significant WBDV. Literature review analyses and BrainSpan analysis based on the human brain developmental transcriptome were performed to detect the potential role of genetic risk factors in human brain development. RESULTS: We recruited a total of 253 NDD patients. Among them, 26 had significantly decreased WBDV (<-2 standard deviations [SDs]), and 14 had significantly increased WBDV (>+2 SDs). NDD patients with significant WBDV had higher rates of motor development delay (49.8% [106/213] vs . 75.0% [30/40], P  = 0.003) than patients without significant WBDV. Genetic burden analyses found 30 genes with an increased allele frequency of rare variants in patients with significant WBDV. Analyses of the literature further demonstrated that these genes were not randomly identified: burden genes were more related to the brain development than background genes ( P  = 1.656e -9 ). In seven human brain regions related to motor development, we observed burden genes had higher expression before 37-week gestational age than postnatal stages. Functional analyses found that burden genes were enriched in embryonic brain development, with positive regulation of synaptic growth at the neuromuscular junction, positive regulation of deoxyribonucleic acid templated transcription, and response to hormone, and these genes were shown to be expressed in neural progenitors. Based on single cell sequencing analyses, we found TUBB2B gene had elevated expression levels in neural progenitor cells, interneuron, and excitatory neuron and SOX15 had high expression in interneuron and excitatory neuron. CONCLUSION Idiopathic NDD patients with significant brain volume changes detected by MRI had an increased prevalence of motor development delay, which could be explained by the genetic differences characterized herein.

BACKGROUND: The HELIOS stent is a sirolimus-eluting stent with a biodegradable polymer and titanium oxide film as the tie-layer. The study aimed to evaluate the safety and efficacy of HELIOS stent in a real-world setting. METHODS: The HELIOS registry is a prospective, multicenter, cohort study conducted at 38 centers across China between November 2018 and December 2019. A total of 3060 consecutive patients were enrolled after application of minimal inclusion and exclusion criteria. The primary endpoint was target lesion failure (TLF), defined as a composite of cardiac death, non-fatal target vessel myocardial infarction (MI), and clinically indicated target lesion revascularization (TLR) at 1-year follow-up. Kaplan-Meier methods were used to estimate the cumulative incidence of clinical events and construct survival curves. RESULTS: A total of 2998 (98.0%) patients completed the 1-year follow-up. The 1-year incidence of TLF was 3.10% (94/2998, 95% closed interval: 2.54-3.78%). The rates of cardiac death, non-fatal target vessel MI and clinically indicated TLR were 2.33% (70/2998), 0.20% (6/2998), and 0.70% (21/2998), respectively. The rate of stent thrombosis was 0.33% (10/2998). Age ≥60 years, diabetes mellitus, family history of coronary artery disease, acute myocardial infarction at admission, and device success were independent predictors of TLF at 1 year. CONCLUSION: The 1-year incidence rates of TLF and stent thrombosis were 3.10% and 0.33%, respectively, in patients treated with HELIOS stents. Our results provide clinical evidence for interventional cardiologists and policymakers to evaluate HELIOS stent. CLINICAL TRIAL REGISTRATION ClinicalTrials.gov, NCT03916432.
