Digital technologies have become an integral part of complete denture restoration. With advancement in computer-aided design and computer-aided manufacturing (CAD/CAM), tools such as intraoral scanning, facial scanning, 3D printing, and numerical control machining are reshaping the workflow of complete denture restoration. Unlike conventional methods that rely heavily on clinical experience and manual techniques, digital technologies offer greater precision, predictability, and efficacy. They also streamline the process by reducing the number of patient visits and improving overall comfort. Despite these improvements, the clinical application of digital complete denture restoration still faces challenges that require further standardization. The major issues include appropriate case selection, establishing consistent digital workflows, and evaluating long-term outcomes. To address these challenges and provide clinical guidance for practitioners, this expert consensus outlines the principles, advantages, and limitations of digital complete denture technology. The aim of this review was to offer practical recommendations on indications, clinical procedures and precautions, evaluation metrics, and outcome assessment to support digital restoration of complete denture in clinical practice.

Objective:To compare the influence of dronedarone and amiodarone on the bleeding risk of patients with atrial fibrillation treated with rivaroxaban anticoagulation.Methods:Clinical data of 81 patients with atrial fibrillation treated with rivaroxaban anticoagulation at Xi'an International Medical Center Hospital from January 2020 to July 2023, including 36 patients treated with dronedarone and 45 patients treated with amiodarone, were retrospectively analyzed. The effects of dronedarone and amiodarone on the anticoagulation of rivaroxaban were compared using the incidence of bleeding events, thrombosis events, and adverse reactions as outcome measures.Results:The total bleeding in the dronedarone group [22.22% (8/36)] was significantly higher than that in the amiodarone group [6.67% (3/45)] ( χ2 = 4.12, P < 0.05). The total bleeding of conventional-dose rivaroxaban in the dronedarone group was 30.00% (6/20), while the total bleeding of low-dose rivaroxaban was 12.50% (2/16), with no statistical significance ( χ2 = 1.58, P > 0.05). No thrombotic events or adverse reactions to dronedarone or amiodarone were observed in all patients. Conclusion:Compared with amiodarone, dronedarone significantly increases the bleeding risk of rivaroxaban anticoagulation in patients with non-valvular atrial fibrillation, and reducing the dose of rivaroxaban in patients using dronedarone does not reduce the bleeding risk.

Objective To observe the value of nomogram obtained with multivariate logistic regression based on ultrasound for predicting residue of benign thyroid nodules after microwave ablation(MWA).Methods Totally 101 patients with 133 benign thyroid nodules who underwent ultrasound-guided MWA were retrospectively enrolled.The nodules were divided into residual group(n=21)and non-residual group(n=112)according to follow-up results of contrast-enhanced ultrasound(CEUS)1 month after MWA.The ultrasonic performances of nodules before MWA were compared between groups,and those being statistically different were included in a multivariate logistic regression model to identify the independent predictors for residue after MWA,and the model was then visualized as a nomogram.The discrimination of the nomogram for predicting residue after MWA was assessed with receiver operating characteristic curve and area under the curve(AUC),and its calibration was assessed with Hosmer-Lemeshow goodness-of-fit test.Results High ablation risk and nodules volume shown with ultrasound were both independent predictors of residue of benign thyroid nodules after MWA(both P＜0.05),indicating that benign thyroid nodules with high ablation risk(OR=17.637[2.528,123.019])and large volume(OR=1.297[1.155,1.457])had relatively higher risk of residue after MWA.AUC of the nomogram was 0.756 for predicting residue of benign thyroid nodules after MWA,while Hosmer-Lemeshow test showed good fit(P=0.401).Conclusion Benign thyroid nodules with high ablation risk and large volume shown with ultrasound had relatively high risk of residue after MWA,which could be predicted conveniently and effectively with the obtained nomogram.

Objective: To understand the distribution of tobacco retailer within 100 meters outside middle schools in Wuhan City and its impact on smoking behavior of middle school students, so as to provide basis and feasible suggestions for the development of tobacco control policy for adolescents. Methods: From February to May 2023, a multi stage stratified cluster random sampling method was used to select 20 middle schools from 4 districts in Wuhan City. To investigate the distribution of tobacco retailer within 100 metres outside the school and the sale of tobacco to minors. A total of 4 882 students were surveyed using the core questions of the 2021 Chinese Adolescent Tobacco Prevalence Questionnaire. Fisher exact probability test, Chi square test and Chi square trend test were used for statistical analysis. Results: Nearly 70.00% of middle schools had tobacco retailer within 100 metres, with an average of (1.10±0.97) per middle school. The awareness rate (100.00%) and labeling rate (87.50%) of licensed tobacco retailer were higher than those of non licensed tobacco retailer (33.33%, 16.67%) ( P <0.05). The rates of tried smoking, current smoking and buying cigarettes within 30 days were 7.13%, 1.99% and 2.54%, respectively. The rates of students who tried smoking ( 8.58 %), current smoking (2.29%) and buying cigarettes within 30 days (2.85%) in schools with tobacco retailer within 100 metres were higher than those in schools without tobacco retailer (3.79%, 1.28%, 1.83%)( χ 2=35.80, 5.37, 4.37 , P <0.05). And as the grade increased, the rates of tried smoking, current smoking and buying cigarettes among middle school students all showed an upward trend ( χ 2 trend =66.20, 36.10, 16.17, P <0.05). Conclusions Middle school students in Wuhan City have high tobacco availability. The findings suggest that school ban should be extended from 50 meters to 100 meters, and the regulatory authorities must strictly prohibit selling tobacco products to minors at tobacco retailer.

Objective: To analyze the characteristics of a norovirus outbreak in a kindergarten, and factors affecting the detoxification time, so as to provide a scientific basis for targeted control measures. Methods: On February 24,2023, the basic personal information, clinical manifestations，morbidity and treatment of 16 kindergarten cases with a norovirus outbreak in Wuhan were collected. Anal swabs were collected every 7 d after the outbreak to detect norovirus. Chisquare test was used for comparison of intergroup rates. The comparison of detoxification time between different groups was conducted by Logrank test, and the influencing factors of detoxification time in cases were analyzed by Cox multiple regression analysis. Results: From February 19-28, 2023, a total of 18 cases were reported and 16 of them participated in the detoxication time monitoring. In the first, second, third and fourth sampling after the outbreak, the positive rates were 60.00%, 100.00%, 75.00% and 0, respectively. The reverse transcriptionpolymerase chain reaction cycle threshold (Ct values) were (25.83±5.74, 28.83±5.55, 36.13±4.30), and undetected, respectively. The median time of detoxification was 19.42 d with 95%CI=(18.21-20.64)d. The results of Cox regression showed that the detoxication time was shorter in the treatment group than in the nontreatment group[HR(95%CI)=5.09(1.39-18.58), P<0.05]. Conclusion Children infected with norovirus has a long duration of detoxification,and case management, which could be shortened by drugs, and disinfection should be strengthened after the case returned to school.

Objective:Pediatric chronic sinusitis （CRS） is a common disease within the field of otolaryngology-head and neck surgery. Due to the immaturity of sinus development and immune competence in children, its etiology and pathophysiology are complex, and its clinical features and outcomes differ significantly from those in adult patients. Currently, there are issues in the diagnosis and treatment of pediatric CRS, particularly in areas such as antibiotic use and surgical interventions, owing to a lack of sufficient attention. In recognition of this, the Chinese Rhinopathy Research Cooperation Group developed this expert consensus based on a systematic review of the latest literatures from both domestic and international sources, with reference to the latest evidence-based medical evidence worldwide, and in combination with their own clinical experience. The consensus covers various aspects including epidemiology, predisposing factors, pathophysiology, diagnosis and differential diagnosis, as well as treatment strategies such as medical therapy and surgical intervention. It aims to standardize the clinical diagnosis and treatment of pediatric CRS, improve clinical efficacy and patient satisfaction, reduce clinical expenditures, and decrease the occurrence of adverse reactions.

Autologous ozonized blood transfusion(AOBT) is a therapy of re-transfusion of 100-200 mL of autologous blood after shaking and agitation with appropriate amount of oxygen-ozone in vitro. The oxidation of blood through the strong oxidation of ozone can enhance the non-specific immune response of the body, regulate the internal environment and promote health. This therapy has been increasingly applied in clinical practice, while no unified standard for the operation process in terms of ozone concentration, treatment frequency and treatment course had been established. This operation process of AOBT is primarily explored in order to standardize the operation process and ensure its safety and efficacy.

Objective:To understand the work experience and service quality of "Internet plus Nursing Service" led by tertiary hospitals to lay the foundation for building an "Internet plus Nursing Service" quality control index system suitable for China's national conditions.Methods:Using field research method, combining purposive sampling with open sampling, from September 2021 to February 2022, the 11 "Internet plus Nursing Service" visiting nurses from 10 residential areas in Shibei District, Shinan District, Laoshan District, Chengyang District and Jimo District of Qingdao were observed for 5 months.Results:The work experience of "Internet plus Nursing Service" visiting nurses: meeting the rigid needs of society and patients, and nurses′ professional value and satisfaction were multiplied; there were still shortcomings in the regulatory mechanism, and information technology construction needed to be continuously strengthened; there were still hidden dangers in patient safety and nurse professional safety issues. Six key factors influencing the quality of Internet plus nursing service were analyzed: non-standard preparation of articles before visiting, non-standard dress for door-to-door service, inadequate preparation for pre operation evaluation, lack of empathy during operation, weak awareness of infection prevention outside the hospital, and failure to carry out health education based on patients′ conditions after operation.Conclusions:The Internet plus nursing service model is dominated by the tertiary hospitals in Qingdao, which has realized two-way referral between the community and the superior hospitals, and has effectively improved the quality of extended care. The acceptance and satisfaction of patients and their families are high, and nurses′work enthusiasm and professional value have increased significantly. It is still necessary to establish and improve theInternet plus nursing service work standards to achieve the homogenization and diversification of nursing services, promote the comprehensive quality of community medical staff.
