To evaluate the application value of the Peyton four-step teaching method in the standardized training of intestinal ultrasound and compare it with traditional teaching methods, so as to provide an optimized approach for clinical ultrasound training. Participants from the Department of Ultrasound at Peking Union Medical College Hospital between September 2024 and March 2025 were randomly assigned to either the traditional group or Peyton group. The traditional group followed the conventional "lecture- demonstration-practice" model, while the Peyton group implemented the standardized "demonstration-deconstruction-comprehension-execution" four-step approach. All training focused on standard intestinal ultrasound scanning techniques. After the training, the operational skills were independently evaluated by the instructors. To verify the reproducibility of the teaching method, the participants in traditional teaching group received additional Peyton method training after the initial assessment and underwent a second evaluation. A total of 18 participants were included in this study, with 9 in the traditional teaching group and 9 in the Peyton teaching group. Participants in the Peyton group demonstrated significantly higher scores than those in the traditional group at every anatomical site assessed (all The Peyton four-step method is significantly more effective than traditional teaching in improving residents' intestinal ultrasound skills, demonstrating its suitability as the preferred approach for standardized training programs.

Efferocytosis refers to the process of phagocytes engulfing and clearing the cells after programmed cell death. In recent years, an increasing number of studies have shown that the mechanisms of efferocytosis are closely related to drug-induced liver injury, hepatic ischemia-reperfusion injury, viral hepatitis, cholestatic liver diseases, metabolic-associated fatty liver disease, alcoholic liver disease, and other liver disorders. This review summarized the research progress on the role of efferocytosis in liver diseases, with the hope of providing new targets for the prevention and treatment of liver diseases.

Pulpotomy, which belongs to vital pulp therapy, has become a strategy for managing pulpitis in recent decades. This minimally invasive treatment reflects the recognition of preserving healthy dental pulp and optimizing long-term patient-centered outcomes. Pulpotomy is categorized into partial pulpotomy (PP), the removal of a partial segment of the coronal pulp tissue, and full pulpotomy (FP), the removal of whole coronal pulp, which is followed by applying the biomaterials onto the remaining pulp tissue and ultimately restoring the tooth. Procedural decisions for the amount of pulp tissue removal or retention depend on the diagnostic of pulp vitality, the overall treatment plan, the patient's general health status, and pulp inflammation reassessment during operation. This statement represents the consensus of an expert committee convened by the Society of Cariology and Endodontics, Chinese Stomatological Association. It addresses the current evidence to support the application of pulpotomy as a potential alternative to root canal treatment (RCT) on mature permanent teeth with pulpitis from a biological basis, the development of capping biomaterial, and the diagnostic considerations to evidence-based medicine. This expert statement intends to provide a clinical protocol of pulpotomy, which facilitates practitioners in choosing the optimal procedure and increasing their confidence in this rapidly evolving field.

Intentional tooth replantation (ITR) is an advanced treatment modality and the procedure of last resort for preserving teeth with inaccessible endodontic or resorptive lesions. ITR is defined as the deliberate extraction of a tooth; evaluation of the root surface, endodontic manipulation, and repair; and placement of the tooth back into its original socket. Case reports, case series, cohort studies, and randomized controlled trials have demonstrated the efficacy of ITR in the retention of natural teeth that are untreatable or difficult to manage with root canal treatment or endodontic microsurgery. However, variations in clinical protocols for ITR exist due to the empirical nature of the original protocols and rapid advancements in the field of oral biology and dental materials. This heterogeneity in protocols may cause confusion among dental practitioners; therefore, guidelines and considerations for ITR should be explicated. This expert consensus discusses the biological foundation of ITR, the available clinical protocols and current status of ITR in treating teeth with refractory apical periodontitis or anatomical aberration, and the main complications of this treatment, aiming to refine the clinical management of ITR in accordance with the progress of basic research and clinical studies; the findings suggest that ITR may become a more consistent evidence-based option in dental treatment.

Objective To explore the rehabilitative effects of flash cupping combined with respiratory training in patients with occupational pneumoconiosis (hereinafter referred to as "pneumoconiosis"). Methods A total of 94 patients with pneumoconiosis were selected as the study subjects by the convenient sampling method. Participants were divided into treatment group and control group based on pneumoconiosis stage using the stratified block randomization method, with 47 cases in each group. The patients in the control group received routine symptomatic treatment, and the patients in the treatment group received flash cupping therapy combined with respiratory training in addition to the routine treatment for six weeks. Diaphragmatic displacement (DD), 6-minutes walking distance (6MWD), metabolic equivalents of task (MET), predicted percentage of forced vital capacity (FVC%), predicted percentage of forced expiratory volume in one second (FEV1%), Chronic Obstructive Pulmonary Disease Assessment Test (CAT) score, and the modified British Medical Research Council Respiratory Questionnaire (mMRC) were assessed before treatment, after six weeks of treatment, and three months after completion of treatment. Results Before treatment, no significant differences were observed in patients between the two groups in DD, 6MWD, MET, FVC%, FEV1%, CAT score, or mMRC grade (all P>0.05). DD, 6MWD, and MET of patients in the treatment group were higher than those before treatment in the same group and those of the control group at the corresponding time points after six weeks of treatment (all P<0.05). In addition, the CAT score of patients in the treatment group was lower than that before treatment (P<0.05). At three months after treatment, 6MWD and MET of patients in the treatment group were higher than those before treatment and those of the control group at the same time points (all P<0.05). There were no significant differences in FVC%, FEV1% and mMRC grade of patients between the two groups (all P>0.05). Conclusion Flash cupping combined with respiratory training can improve the diaphragmatic function, exercise endurance and quality of life of patients with pneumoconiosis, and has improved exercise endurance, which can be used as a useful supplementary treatment in the pulmonary rehabilitation of pneumoconiosis.

Objective:To explore the effect of the interaction between plasma aluminum concentration and schooling year on cognitive function, it provides the basis for early identification of its damaging effect.Methods:From October to December, 2014, 1114 on-the-job aluminum exposed workers in a large aluminum factory in Shanxi Province were investigated. The plasma aluminum concentrations were measured by inductively coupled plasma-mass spectrometry (ICP-MS) as an internal exposure indicator. The subjects were divided into low, medium, and high aluminum exposure group based on the blood lead concentration levels. The general information was collected with a self-designed questionnaire, and their cognitive function was evaluated with the mini-mental state examination and the clock drawing test. The interaction between plasma aluminum concentration level and education level was analyzed by using unconditional logistic regression fitting multiplication model and cross analysis fitting addition model.Results:The average level of plasma aluminum of the subjects was 21.68 (10.51, 45.78) μg/L. The detection rate of cognitive impairment was 19.9%. The influencing factors of cognitive function were plasma aluminum concentration, age, education level and marital status, among which high schooling year, and being married were the protective factors (all P<0.05), plasma aluminum concentration, and age were the risk factors (all P<0.05) ; After adjusting the confounding factors, such as age, marital status, schooling year, income level, smoking, and drinking, logistic regression model and the multiple linear regression model showed that there was a dose response relationship between plasma aluminum concentration and cognitive impairment. With the increase of plasma aluminum concentration, the score gradually decreased, and the risk of cognitive impairment increased ( Ptrend<0.05) ; There were multiplicative interaction ( AOR=2.15, 95% CI: 1.10-4.19) and additive interaction ( RERI=5.38, 95% CI: 2.60-8.16; AP=0.65, 95% CI: 0.51-0.80; S=3.88, 95% CI: 2.00-7.56) between plasma aluminum concentration and low schooling year on cognitive function. Conclusion:There was a dose-response relationship between aluminum exposure and cognitive impairment. There was an interaction between aluminum exposure and low schooling year. When both of them worked together, the risk of cognitive impairment increases.
