摘要： Objective To investigate the prevalence of functional gastrointestinal disorders（FGIDs）among naval officers and sailors and analyze their related influencing factors. Methods From September 2022 to June 2023，a survey on FGIDs was carried out in the Eastern Theater Command，Northern Theater Command，Southern Theater Command，and coastal defense garrisons on islands by simple random sampling method. This study used a self-designed questionnaire，and was completed by on-site distribution and collection of the questionnaire. The items of the questionnaire included demographic information，clinical history，gastrointestinal symptoms in the recent three months，dietary status，sleep status，and so on. Based on the electronic database system，a study cohort of FGIDs related clinical data was established. And the logistic regression model was used to analyze the related factors of FGIDs. Results A total of 7，500 questionnaires were distributed and 6，297 valid questionnaires were collected，with an effective recovery rate of 83.96%. The seven most common FGIDs subclasses were irritable bowel syndrome，functional dyspepsia，functional constipation，functional diarrhea，hypersensitivity to reflux，functional chest pain，and nausea and vomiting，with an overall incidence of 34.63%. Among the survey respondents，55.44% reported having a very regular dietary routine，42.42% occasionally having irregular eating habits，and 2.14% having relatively irregular eating patterns. Additionally，84.98% of the respondents practiced individual dining，and cooked meals took 99.65%. The overall sleep duration of the naval officers and sailors was（6.91 ± 1.01）h/d，42.18% of the respondents reported very satisfied and 45.50% reported relatively satisfied with their sleep. Among the group that experienced significant daytime sleepiness（n=705），the sleep duration was（6.37 ± 1.01）h/d，10.92% reported very satisfied and 43.83% reported relatively satisfied with their sleep. A multivariate analysis identified 11 potential fac

摘要： Objective To understand the influencing factors for cardio-cerebrovascular complications in patients with T2DM and construct a nomogram risk prediction. Methods The study design was a prospective observational study, and the subjects were selected from hospitalized patients with T2DM admitted to Huangshan City People′s Hospital from May 2022 to April 2023. Data on patients' gender, age, body mass index, alcohol consumption, smoking status, family history of cardio-cerebrovascular diseases, insulin use, duration of diabetes, blood pressure, and routine laboratory test results were collected using the hospital electronic medical record system. At discharge, patients were assessed using the T2DM-Specific Medication Belief Scale (total score range: 10-50), Medication Literacy Assessment Scale (total score range: 0-7), and Morisky Medication Adherence Scale (total score range: 0-8). Patients were followed up by telephone for 6 months after discharge and divided into 2 groups based on the occurrence of cardio-cerebrovascular complications. Logistic regression analysis was performed using SPSS 26.0 software to identify influencing factors for cardio-cerebrovascular complications in T2DM patients. A nomogram prediction model was constructed using R 4.1.0 software, and internal validation of the model was conducted using the Bootstrap method. Results A total of 294 T2DM patients were included in the analysis. The medication belief score was (32.6±5.6) score, the medication literacy score was (4.2±0.5) score, and the medication adherence score was (6.1±0.8) score. During the 6-month follow-up, a total of 43 patients (14.6%) experienced cardio-cerebrovascular complications, including of coronary heart disease (23 cases), heart failure (12 cases), and stroke (8 cases). Compared to patients without cardio-cerebrovascular complications, patients with complications had higher body mass index, glycosylated hemoglobin A1c (HbA1c), D-dimer, and uric acid levels, as well as lower medi

摘要： The diving breathing apparatus is the core component of diving equipment. In order to ensure the safety of using breathing apparatus，it is necessary to evaluate its performance. In this study，according to the functional performance requirements of self-contained open-circuit compressed air underwater breathing apparatus，13 unmanned performance evaluation factors were screened out，and the threshold method in the linear non-dimensionalization method was adopted for data processing. The hierarchical structure model was constructed based on the analytic hierarchy process，and the weights of different evaluation factors were determined in combination with the evaluation objects and usage requirements and then a comprehensive evaluation system for the unmanned performance of self-contained open-circuit diving breathing apparatus was established. The various unmanned performance indicators of diving breathing apparatus were converted into the overall evaluation value，which provide a basis for the scientific evaluation of the comprehensive performance of diving breathing apparatus. © 2025 Chinese Medical Journals Publishing House ***.
