RÉSUMÉ
Objective:Digestive endoscopy is an important diagnostic and therapeutic tool for digestive system diseases.The artificial intelligence(AI)-assisted system in endoscopy(hereinafter referred to as AI in digestive endoscopy)has broad application prospects in the field of digestive endoscopy.The trust and acceptance of endoscopic subjects are the cornerstone of the research,application,and promotion of AI in digestive endoscopy.Currently,the tools for measuring the acceptance of AI in digestive endoscopy by subjects are limited at home and abroad.This study aims to develop a scale for measuring the acceptance of AI in digestive endoscopy by subjects,then to evaluate its reliability and validity. Methods:By conducting literature research,an item pool and dimensions were constructed,and a preliminary scale was constructed using Delphi method.Through the first stage of the survey on the subjects,the reliability and validity of the scale were tested,and the revised scale was used for the second stage of survey on the subjects to further verify the structural validity of the scale. Results:The acceptance scale for AI in digestive endoscopy included 11 items in 3 dimensions:accuracy,ethics,benefit and willingness.In the first stage of the survey,351 valid questionnaires were collected,and the Cronbach's α was 0.864.The correlation coefficient between the total score of the scale and the score of the test item was 0.636,and the Kaiser-Meyer-Olkin(KMO)value in exploratory factor analysis was 0.788.In the second stage of the survey,335 valid questionnaires were collected,and in confirmatory factor analysis,the χ2/df was 3.774,while the root mean squared error of approximation(RMSEA)was 0.091. Conclusion:Acceptance scale for AI in digestive endoscopy by subjects developed in this study has good reliability and validity.

OBJECTIVES@#Gastrointestinal endoscopy plays an important role in the diagnosis and treatment of gastrointestinal diseases. The satisfaction degree of gastrointestinal endoscopy can directly affect the patient's compliance and further impact the treating effect. At present, there is no scale to evaluate the satisfaction degree of gastrointestinal endoscopy in China. This study aims to develop a satisfaction scale of gastrointestinal endoscopy suitable for national conditions and to evaluate its reliability and validity, which provides a tool for clinic to evaluate patients' satisfaction with gastrointestinal endoscopy.@*METHODS@#The original gastrointestinal endoscopy satisfaction scale was compiled by literature review, consulting senior endoscopists and experts. Through the first round of survey about 120 patients, the original scale was analyzed and modified according to the results to get the gastrointestinal endoscopy satisfaction scale (formal scale). The formal scale was used to conduct the second round of survey about 200 patients. The reliability and validity of the scale were analyzed and evaluated according to the survey results.@*RESULTS@#The reliability of the original scale was good but the validity was poor. The formal scale had 2 dimensions and 10 items, the Cronbach's alpha and split-half reliability were 0.889 and 0.823. The structure validity index χ2/df was 2.513, root mean square error of approximation (RMSEA) was 0.094, goodness of fit index (GFI) was 0.914, adjusted goodness of fit index (AGFI) was 0.861, comparative fit index (CFI) was 0.946, normed fit index (NFI) was 0.915. The aggregate validity was general, the discriminative validity was good, and the direct score of patients was strongly correlated with the total score of the scale.@*CONCLUSIONS@#The gastrointestinal endoscopy satisfaction scale has good reliability and validity, which can be used as a tool to evaluate patients' satisfaction with gastrointestinal endoscopy in China.

The morbidity of inflammatory bowel diseases (IBD) is rising rapidly but no curative therapies to prevent its recurrence. Cell death is crucial to maintaining homeostasis. Necroptosis is a newly identified programmed cell death and its roles played in IBD need to be explored. Necroptosis is mediated by receptor interacting protein kinase 1 (RIPK1), RIPK3, and mixed lineage kinase domain-like protein (MLKL), which resulted in cell swelling, plasma membrane rupture, intracellular content leaking, and eventually cell death as well as the promotion of inflammation. Studies have found that inhibiting necroptosis alleviated IBD in animal models and IBD patients with an increased level of necroptosis in inflammatory tissues, indicating that necroptosis is related to the pathogenesis of IBD. However, due to the complexity in regulation of necroptosis and the involvement of multiple functions of relevant signaling molecules, the specific mechanism remains elusive. Necroptosis may play a vital regulatory role in the pathogenesis of IBD, which provides a new idea and method for further exploring the therapeutic target of IBD.

Objective To investigate the prevalence rate of hyperlipidemia in the middle-aged and elderly in Guangxi Hei Yi Zhuang population. Methods A total of 657 people of Hei Yi Zhuang nationality aged 40 years and over were surveyed. Blood pressure, body height, body weight, serum lipid and apolipoprotein levels were measured, and both body surface areas and body mass index were calculated. The results were compared with those in 520 people of Han nationality who also live in that district. Results The prevalence of hypercholesterolemia, hypertriglyceridemia, and hyperlipidemia in Hei Yi Zhuang vs. Han population were 28.9% vs. 35.8%(P0.05), and 36.2% vs. 42.3%(P0.05) respectively. Conclusions Prevalence of hyperlipidemia of Hei Yi Zhuang is lower than that of Han ethnic group, which might results from different dietary habit, life style, physical activity, and even genetic background.
