Objective To explore the influence of the medical and health management model based on artificial intelligence (AI) on type 2 diabetes mellitus (T2DM) combined with masked hypertension (MH). Methods A total of 342 patients with T2DM admitted to the hospital from May 2021 to August 2024 were selected as research subjects, and the incidence rate of MH was counted. All patients were classified into the reference group (routine management) and the study group (AI+medical health management) according to the random number table method, with 171 cases in each group. The self-management, glycolipid metabolism and ambulatory blood pressure were compared between both groups before and after intervention. Results Among the 342 patients with T2DM, MH occurred in 34 cases, with an incidence rate of 9.94% (34/342). The self-management ability in the two groups was improved after 6 months and 12 months of intervention, and the self-management ability was higher in the study group (P<0.05). After 6 months and 12 months of intervention, the glucolipid metabolism indexes in both groups were optimized, and the improvements in the study group were greater (P<0.05). The daytime average systolic blood pressure and diastolic blood pressure, 24 h average systolic blood pressure and diastolic blood pressure were decreased in both groups after 6 months and 12 months of intervention, and the study group showed lower indexes (P<0.05). Conclusion T2DM are prone to MH. AI medical and health chronic disease management can enhance patients' self-management ability, help improve glucose and lipid metabolism, lower blood pressure, and help reduce the risk of MH.

Objective To analyze the distribution characteristics and trends of occupational exposure types of medical radiation workers in Gansu Province, China, and to provide a basis for administrative departments to formulate and adjust radiation protection policies. Methods According to the radiation health information platform, the data of occupational exposure types of radiation workers in Gansu Province from 2014 to 2023 were obtained. The proportions of occupational exposure types in each physical examination year was statistically analyzed. Results From 2014 to 2023, the number of medical radiation workers accounted for more than 70% of the total number of radiation workers. The proportion of X-ray imaging diagnostic radiation workers in the total number of medical radiation workers gradually decreased but remained the highest, exceeding 68% annually. The proportion of interventional radiology workers in the total number of medical radiation workers increased from 13.8% to 25.5%. The proportions of radiation therapy and nuclear medicine workers in the total number of medical radiation workers increased slowly. The numbers of interventional radiology and radiotherapy workers in tertiary hospitals both accounted for more than 70% of the total number of such workers in the province. The proportion of interventional radiology workers increased and then decreased. The proportion of radiotherapy workers increased significantly from 70.5% to 93.0%. The number of nuclear medicine workers in tertiary hospitals accounted for more than 80% of such workers in the province. Conclusion Radiation protection policies and measures should be adjusted according to the changes in the types of occupational exposure. The focus of these policies and measures should differ depending on the level of healthcare institutions, the type of radiological diagnostic and therapeutic services, and the characteristics of various occupational exposure types .

Objective To evaluate the application value of prone-position ultrasound in assessing retrorenal colon among patients scheduled for percutaneous nephrolithotomy(PCNL).Methods A total of 651 patients scheduled for PCNL were enrolled.All patients underwent preoperative supine-position computed tomography(CT)and prone-position ultrasound to assess retrorenal colon.Retro-renal colon was defined as segment of the colon located posterior to the kidney,with its inferior mar-gin extending beyond the lower pole of the kidney.The degree of coverage was classified as mild(≤3.0 cm),moderate(＞3.0 cm without extending beyond the renal hilum)and severe(extending be-yond the renal hilum).Patients diagnosed with retrorenal colon by ultrasound underwent further eval-uation using prone-position CT.Concordance between ultrasound and supine-position or prone-posi-tion CT in diagnosing and classifying retrorenal colon was compared,and the impact on puncture pathway selection and surgical approach was analyzed.Results Among 651 patients,prone-position ultrasound identified retrorenal colon in 57 patients,including 43 mild cases,11 moderate cases,and 3 severe cases.Prone-position CT identified retrorenal colon in 55 patients,including 42 mild cases,10 moderate cases,and 3 severe cases.Supine CT identified retrorenal colon in 26 patients,inclu-ding 23 mild cases,2 moderate cases,and 1 severe case.The detection rate of retrorenal colon by supine CT was significantly lower than that by prone-position ultrasound(P＜0.05).In 12 patients(4 mild cases,7 moderate cases,1 severe case),the puncture pathway was modified based on ultra-sound diagnosis,and 2 patients with severe involvement underwent a change in surgical approach.Conclusion Prone-position ultrasound demonstrates good agreement with prone-position CT in the assessment of retrorenal colon.

Paraplegia caused by spinal cord injury is a serious neurological complication, for which surgery is currently the main treatment method. Due to different surgical approaches, patients are usually expected to maintain a passive prone position for a long time or switch between the supine and prone positions. Affected by multiple factors such as neurogenic sensory disorders, pathological changes in muscle tone and operative duration, the risk of intraoperative acquired pressure injury (IAPI) is significantly increased. Current clinical prevention strategies for IAPI in these patients predominantly focus on localized pressure relief during positioning, lacking systematic, standardized comprehensive prevention protocols or evidence-based guidelines. To address it, Department of Nursing, Orthopedics Branch, China International Exchange and Promotive Association for Medical and Health Care, Spinal Trauma Professional Committee, Orthopedics Branch, Chinese Medical Doctor Association, Nursing Group of Spine and Spinal Cord Professional Committee of Chinese Association of Rehabilitation Medicine organized experts in relevant fields to formulate Guideline for the prevention of intraoperative acquired pressure injury in paraplegic patients with spinal cord injury ( version 2025), based on evidence-based medical evidence and latest research results and clinical practice at home and abroad. Eleven recommendations were put forward from the aspects of preoperative risk assessment, intraoperative prevention strategies, postoperative handover and monitoring, and supportive mechanisms for IAPI prevention, aiming to standardize the prevention measures and management strategies of IAPI in paraplegic patients with spinal cord injury and accelerate the recovery of patients and improve the therapeutic effect.

Objective To explore the impact of the intervention model based on self-efficacy theory on fear of progression (FoP), negative emotions, and cancer-related fatigue in patients with hepatocellular carcinoma undergoing transcatheter arterial chemoembolization (TACE). Methods The clinical data of 94 patients with primary liver cancer were retrospectively analyzed. The patients were divided into control group and observation group according to different intervention methods, with 47 patients in each group. The control group received routine nursing mode after discharge, while the observation group received intervention model based on self-efficacy theory. Both groups were intervened for 3 months after discharge. The self-efficacy[General Self-Efficacy Scale (GSES)]at discharge and one- and three-month after discharge, FoP[Fear of Progression Questionnaire-Short Form (FoP-Q-SF)], negative emotions[Self-rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS)], cancer-related fatigue[Revised Piper Fatigue Scale (R-PFS)], and quality of life[Quality of Life Questionnaire for Liver Cancer Patients (QOL-LC V2.0)] at discharge and three-month after discharge were compared between the two groups. Results One month and three months after discharge, the GSES scores of both groups gradually increased compared to those at discharge, and the scores of the observation group were higher than those of the control group (P < 0.05). Three months after discharge, the total and sub-dimension scores of FoP-Q-SF, SAS scores, SDS scores, and R-PFS were lower in both groups compared to those at discharge, and the observation group had lower scores than the control group (P < 0.05). Three months after discharge, the total and sub-dimension scores of QOL-LC V2.0 were higher in both groups compared to those at discharge, and the observation group had higher scores than the control group (P < 0.05). Conclusion The intervention model based on self-efficacy theory can enhance the self-efficacy of patients with primary liver cancer after TACE, relieve negative emotions and severity of FoP, improve cancer-related fatigue, and enhance the quality of life.

Objective To analyze micronucleus abnormalities in the peripheral blood lymphocytes of industrial radiation workers and the influencing factors, and to provide a reference for radiation protection. Methods The occupational health monitoring data of 661 industrial radiation workers were collected from the occupational health examination system of Gansu Provincial Center for Disease Control and Prevention. The abnormalities in the micronucleus of peripheral blood lymphocytes were analyzed. The influencing factors were identified by logistic regression. Results The micronucleus abnormality rate was 6.05% for the 661 industrial radiation workers. There was no significant difference in micronucleus abnormality rate between sexes (P > 0.05). Comparison of age groups showed that the rate of micronucleus abnormality increased with age, and workers over 50 years of age has the highest rate of micronucleus abnormalities (17.81%); there was a significant difference between age groups (P < 0.05). There was a significant difference in micronucleus abnormality rate between occupational categories (P < 0.05). There was a significant difference in micronucleus abnormality rate between groups with different years of work (P < 0.05). Logistic regression analysis showed that age and years of work were the risk factors for micronucleus abnormality rate (P < 0.05); age was an independent risk factor for micronucleus abnormality rate (P < 0.05). Conclusion The effect of low-dose ionizing radiation on micronucleus abnormality rate of industrial radiation workers is related to age and working years. Attention should be paid to occupational health monitoring of radiation workers, especially those with advanced age.
