Apical microsurgery is accurate and minimally invasive, produces few complications, and has a success rate of more than 90%. However, due to the lack of awareness and understanding of apical microsurgery by dental general practitioners and even endodontists, many clinical problems remain to be overcome. The consensus has gathered well-known domestic experts to hold a series of special discussions and reached the consensus. This document specifies the indications, contraindications, preoperative preparations, operational procedures, complication prevention measures, and efficacy evaluation of apical microsurgery and is applicable to dentists who perform apical microsurgery after systematic training.

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.

Thyroid diseases are clinically prevalent endocrine and metabolic disorders, including various types such as Hashimoto's thyroiditis and thyroid nodules. Their pathogenesis is complex and influenced by numerous factors, potentially involving genetic factors, environmental factors, and immune dysfunction. With the continuous advancement of modern traditional Chinese medicine (TCM), TCM has established a unique theoretical system in the prevention and treatment of thyroid diseases, with increasingly rich clinical practical experience. This article reviews the recent application of TCM health status analysis, monitoring, early warning, and prevention in the field of thyroid diseases, aiming to provide useful references for in-depth study in this field.

Objective:To explore the predictive value of non-high-density lipoprotein cholesterol (non-HDL-C) combined with left ventricular ejection fraction (LVEF) for in-stent restenosis (ISR) in patients with coronary heart disease (CHD).Methods:Clinical data of 476 CHD patients who underwent percutaneous coronary intervention (PCI) at the Affiliated Hospital of Jining Medical University from January 2021 to December 2022 were retrospectively analyzed. All patients underwent postoperative coronary angiography reexamination, and were divided into the ISR group (257 cases) and non-ISR group (219 cases) according to the reexamination results. Baseline data were compared between the two groups. Multivariate logistic regression analysis was used to identify the influencing factors of ISR, and receiver operating characteristic (ROC) curve was applied to analyze the predictive value of non-HDL-C, LVEF, and their combination for ISR.Results:The proportion of complicated hypertension, levels of low-density lipoprotein cholesterol (LDL-C) and non-HDL-C in the ISR group were higher than those in the non-ISR group (all P<0.05), while LVEF and stent diameter were smaller than those in the non-ISR group (all P<0.05). Multivariate logistic regression analysis showed that after adjusting for confounding factors, non-HDL-C and LVEF were independent risk factors for ISR in CHD patients after PCI (all P<0.05). ROC curve analysis indicated that the area under the curve (AUC) of non-HDL-C for predicting ISR in CHD patients was 0.648(95% CI: 0.597-0.698, P<0.05), with a sensitivity of 0.461 and specificity of 0.794; the AUC of LVEF for predicting ISR was 0.628(95% CI: 0.577-0.680, P<0.05), with a sensitivity of 0.452 and specificity of 0.863; the AUC of their combination for predicting ISR was 0.701(95% CI: 0.662-0.781, P<0.05), with a sensitivity of 0.782 and specificity of 0.588. Conclusions:Non-HDL-C, LVEF, and stent diameter are independent risk factors for ISR in CHD patients after PCI. Single detection of non-HDL-C or LVEF has predictive value for ISR, and their combination can improve the predictive efficiency, which has higher clinical application value.

Objective To identify potential ergonomic risk factors of works and quickly assess their risks of developing work-related musculoskeletal disorders (WMSDs) in the medical staff. Methods A total of 188 medical staff were selected as the research objects using a two-stage random sampling method. The method for the identification of musculoskeletal stress factors (PLIBEL) was used to analyze the adverse ergonomic factors in the work process, and the rapid entire body assessment (REBA) was used to quickly assess the whole-body posture load. Results The PLIBEL assessment results showed that various adverse ergonomic factors affected different parts of the body during the work process of medical staff. Specifically, 18 adverse ergonomic factors were identified in the neck, shoulders, and upper back, while 10 adverse ergonomic factors were identified in the elbow, forearm, hand, and lower back. Rehabilitation therapists and nurses engaged in patient handling in general wards and medication preparation and blood collection were exposed to ≥35 adverse ergonomic factors. The REBA assessment showed that the REBA score was 3-12 points for medical staff during their work process. Rehabilitation therapists were classified as having an extremely high ergonomic risk. High-risk occupations included ward housekeeping nurses, surgery assistant nurses, operating-room instrument nurses, and surgeons. Medium-risk occupations included general ward nurses (medication preparation and blood collection, venipuncture/infusion, and patient handling), intensive care unit (ICU) nurses, internal medicine residents, and dentists. Low-risk occupations included administrative front-desk nurses, outpatient internal medicine physicians, and technicians/physicians in ultrasonography, laboratory medicine, physical examination, and occupational health departments. Conclusion Adverse ergonomic factors of medical staff predominantly affect the neck, shoulders, upper back, elbows, forearms, hands, and the lower back during the work process. Rehabilitation therapists, ward housekeeping nurses, ICU nurses, operating-room instrument nurses, and surgeons are high-risk groups for WMSDs. Attention should be paid to the management and control of adverse ergonomic factors for medical staff to prevent the occurrence of WMSDs.

Objective To assess the technical levels of computed tomography (CT) quality control testing capabilities among radiological health technology service institutions in Hubei Province, China. Methods Ten radiological health technology service institutions in Hubei Province were organized to participate in an inter-institutional capability comparison of selected indicators in CT quality control testing with reference to the Specification for testing of quality control in X-ray computed tomography (WS 519—2019). The robust Z-score method was employed to evaluate the results of the capability comparison data from the ten institutions. Results Six institutions achieved a "satisfactory" rating in all assessed indicators, with a satisfaction rate of 60%. Indicators rated as "unsatisfactory" or "questionable" included "positioning light accuracy", "uniformity", "noise", and "high-contrast resolution". Conclusion The CT quality control testing capabilities of some radiological health technology service institutions in Hubei Province require further enhancement. Improved training and education for testing personnel are recommended.

Objective:To investigate ferroptosis-related genes in pterygium tissue by using bioinformatic analysis.Methods:The pterygium gene expression profile dataset GSE2513 was downloaded from the Gene Expression Omnibus Database to identify differentially expressed genes (DEGs) related to ferroptosis.Functional annotation and enrichment analysis of the DEGs were performed using Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG).Hub genes were identified from the DEGs using LASSO logistic regression analysis and a support vector machine recursive feature elimination (SVM-REF).Single-gene GSEA analysis was performed on hub genes and a competitive endogenous RNA interaction network was constructed to determine the RNA regulatory relationships of the hub genes.Pterygium tissue samples from 9 patients (9 eyes) undergoing pterygium surgery and conjunctival tissue samples from 9 patients (9 eyes) undergoing strabismus surgery who visited the First Affiliated Hospital of Zhengzhou University were collected from 2022 to 2023 during surgery, and the expression of hub genes and ferroptosis-related marker genes was detected by fluorescence quantitative PCR.This study followed the Declaration of Helsinki, and the study protocol was reviewed and approved by the Ethics Committee of the First Affiliated Hospital of Zhengzhou University (No.2022-KY-0006-001).Results:In the dataset, there were 37 ferroptosis-related genes with significant expression differences, including 16 upregulated genes and 21 downregulated genes.GO analysis revealed significant enrichment in responses to external stimuli, responses to nutritional levels, responses to extracellular stimuli, responses to oxidative stress and starvation, transcription regulatory complexes, and RNA polymerase Ⅱ transcription regulatory complexes, RNA polymerase Ⅱ-specific transcription, and DNA-binding transcription.KEGG analysis showed that the DEGs were primarily enriched in ferroptosis and NOD-like receptor signaling pathways.LASSO regression analysis identified DUOX2, ATF3, NDRG1, EGR1, and ALDH3A2 as hub genes, and SVM-REF analysis identified NDRG1, NF2, IDH2, DUOX2, CHP1, ATF3, and SREBF1 as hub genes. DUOX2, ATF3, and NDRG1 were identified as the intersection hub genes.Single-gene GSEA analysis revealed that DUOX2 was enriched in the cell adhesion molecule CAMs pathway, the heparan sulfate glycosaminoglycan biosynthesis pathway, and the glycosaminoglycan biosynthesis ganglioside series pathway. ATF3 and NDRG1 were enriched in the PPAR signaling pathway and other pathways.Compared with normal conjunctival tissue, the relative expression levels of the ferroptosis markers PTGS2 and TFRC mRNA were increased in pterygium tissue, while the relative expression levels of FTH1, GPX4, SLC40A1, HSPB1, and NFE2L2 mRNA were decreased, with statistically significant differences ( t=12.220, 16.580, 5.664, 6.455, 8.691, 9.883, 17.590; all P<0.01). Conclusions:Ferroptosis may play an important role in the pathogenesis of pterygium. DUOX2, ATF3, and NDRG1 may be the hub genes affecting this complicated process.
