Objective To explore the adverse event signals of children using macrolide drugs （azithromycin, clarithromycin, and erythromycin）, and provide reference for rational medicine use in clinical practice. Methods Data from children under 12 years old were extracted from the US FAERS database spanning from the first quarter of 2004 to the second quarter of 2023. The adverse drug reaction （ADR） signal mining for three macrolide antibiotics was conducted using the Reporting Odds Ratio （ROR） and Bayesian Confidence Propagation Neural Network （BCPNN） methods. Special emphasis was placed on analyzing and contrasting the differences in adverse events among the three drugs. Results A total of 1 615 reports for children under 12 years old were retrieved from the FAERS database, including 1 024 reports of azithromycin, 460 reports of clarithromycin, and 131 reports of erythromycin. Among azithromycin and erythromycin, there were more reports from boys than girls, while for clarithromycin, there were more reports from girls than boys. Oral administration was the most common route of administration for all three drugs. Regarding the outcome of adverse events reported, azithromycin and clarithromycin were primarily associated with other serious adverse events, whereas erythromycin was mainly associated with hospitalization and other serious adverse events. The number of adverse events reported decreased with increasing age, with a higher number of reports in the 0-3 age group. Using the ROR and BCPNN methods for signal detection, 86 signals were identified for azithromycin, 91 for clarithromycin, and 34 for erythromycin. These signals involved 22 System Organ Classes （SOCs）, with azithromycin mainly concentrated in skin and subcutaneous tissue disorders （n=21）, clarithromycin in gastrointestinal disorders （n=15）, and erythromycin in gastrointestinal disorders （n=8）. Twenty-four signals of moderate to high risk were detected, with 13 for azithromycin, 9 for clarithromycin, and 2 for erythromycin. Conclusion The adverse events induced by the three drugs with different risks in different systems. When clinically treating Mycoplasma pneumoniae pneumonia in children, the risk profiles of drugs in different systems should be considered, and personalized dosing should be implemented.

Purpose To investigate the immunohistochemical HER2 expression in a large group of patients with urothelial carcinoma and to compare the results with the pathologic features and survival rate.Methods A total of 519 urothelial carcinoma specimens were collected from two centers.HER2 expression was measured by EnVision immuno-histochemistry.HER2 expression was compared with clinicopathological parameters,and further analyzed in relation to patient prognosis.Results The median age of the 519 patients was 66 years with a male to female ratio of 1.93∶1.Among them,160 cases were radical specimens,and 359 were transurethral resection specimens.The overall HER2 positivity rate was 61.7％(320/519),of which 148 cases(28.5％)were HER2 1+,238(45.9％)were HER2 2+,and 82(15.8％)were HER2 3+.In addition,51 cases(9.8％)were HER2-negative.HER2-positive ex-pression was associated with age,tumor location,histological grade,histological type,surgical approach,lymphovas-cular invasion,and neural invasion(all P＜0.05),but there was no significant correlation with gender,pT stage,muscular invasion,or lymph node metastasis.Univariate and multivariate logistic regression analysis showed that age≥ 66 years,higher tumor grade,and lymphovascular invasion were risk factors for positive HER2 expression,and high histological grade and lymphovascular invasion were independent risk factors affecting HER2 expression after controlling for confounders.Survival analysis showed no significant difference in recurrence-free survival between patients with HER2-positive and HER2-negative non-muscle-invasive urothelial carcinoma(P=0.274).Conclusion High histologic grade,tumor lymphovascular invasion,and neural invasion were associated with positive HER2 expression in patients with urothelial carcinoma,and higher histologic grade and lymphovascular invasion are important factors affect-ing HER2 expression.However,HER2-positive expression may not affect the prognosis of patients with non-muscle-invasive bladder urothelial carcinoma.

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.

Objective:The present study aims to investigate whether there is a shared alteration of the resting-state functional connectivity and amplitude of low frequency fluctuation (ALFF) within the limbic network across all three clinical phases of bipolar disorder.Methods:From July 2019 to December 2021, 107 patients diagnosed with bipolar disorder (bipolar disorder group) were recruited from the Institute of Mental Health at Xiangya Second Hospital, Central South University. Additionally, 46 healthy controls matched for age, gender, and education level were enrolled as the control group. According to the total scores of the Young Mania Rating Scale (YMRS) and the Hamilton Depression Rating Scale (HAMD 17), individuals with bipolar disorder can be categorized into three groups: bipolar manic group, bipolar depressive group, and bipolar euthymic group. Resting state functional magnetic resonance imaging data were collected from all the participants, and seed-based functional connectivity and ALFF in the limbic network were conducted to compare differences among three mood states and controls using One-way ANOVA and post hoc analysis. Finally, correlation analyses using Pearson or Spearman coefficients were performed between statistically significant intergroup differences in functional connectivity/ALFF values and total scores as well as factor scores on clinical rating scales. Results:In comparison to the healthy controls, there was a significant decrease in functional connectivity between the anterior cingulate gyrus and hippocampus across all three clinical phases of bipolar disorder after Bonferroni correction ( t=-2.60--2.07, P<0.05). Furthermore, the ALFF in the anterior cingulate gyrus during three phases showed a significantl reduction following false discovery rate correction ( t=-4.41--3.51, P<0.05). Moreover, a decreased functional connectivity between the left anterior cingulate gyrus and left hippocampus during the depressive phase demonstrated a significant negative correlation with work interest subscores of the HAMD 17 ( r=-0.406, P=0.021). Conclusions:Dysconnectivity and reduced activity within the anterior cingulate of the limbic network may represent common alterations of mood regulation disorder throughout all three clinical phases of bipolar disorder.

Endodontic diseases are a kind of chronic infectious oral disease.Common endodontic treatment concepts are based on the removal of inflamed or necrotic pulp tissue and the replacement by gutta-percha.However,it is very essential for endodontic treatment to debride the root canal system and prevent the root canal system from bacterial reinfection after root canal therapy(RCT).Recent research,encompassing bacterial etiology and advanced imaging techniques,contributes to our understanding of the root canal system's anatomy intricacies and the technique sensitivity of RCT.Success in RCT hinges on factors like patients,infection severity,root canal anatomy,and treatment techniques.Therefore,improving disease management is a key issue to combat endodontic diseases and cure periapical lesions.The clinical difficulty assessment system of RCT is established based on patient conditions,tooth conditions,root canal configuration,and root canal needing retreatment,and emphasizes pre-treatment risk assessment for optimal outcomes.The findings suggest that the presence of risk factors may correlate with the challenge of achieving the high standard required for RCT.These insights contribute not only to improve education but also aid practitioners in treatment planning and referral decision-making within the field of endodontics.

Chemical cleaning and disinfection are crucial steps for eliminating infection in root canal treatment.However,irrigant selection or irrigation procedures are far from clear.The vapor lock effect in the apical region has yet to be solved,impeding irrigation efficacy and resulting in residual infections and compromised treatment outcomes.Additionally,ambiguous clinical indications for root canal medication and non-standardized dressing protocols must be clarified.Inappropriate intracanal medication may present side effects and jeopardize the therapeutic outcomes.Indeed,clinicians have been aware of these concerns for years.Based on the current evidence of studies,this article reviews the properties of various irrigants and intracanal medicaments and elucidates their effectiveness and interactions.The evolution of different kinetic irrigation methods,their effects,limitations,the paradigm shift,current indications,and effective operational procedures regarding intracanal medication are also discussed.This expert consensus aims to establish the clinical operation guidelines for root canal irrigation and a position statement on intracanal medication,thus facilitating a better understanding of infection control,standardizing clinical practice,and ultimately improving the success of endodontic therapy.

Objective A scoping review of research on mobile glucose management in pregnant women with gestational diabetes mellitus was conducted to provide references for clinical providers to conduct mobile glucose management and related research.Methods Based on Arksey and O'Malley's scoping review reporting framework,JBI Library,Cochrane Library,PubMed,Web of Science,Embase,CINAHL Complete,CBM,China National Knowledge In-frastructure(CNKI),and Wanfang Database were retrieved.The search time frame was from the establishment of the databases to February 14,2023.The included literature was screened,summarized and analyzed.Results A total of 65 publications from 11 countries were included,among which 38 were randomized controlled trials,27 were experimental studies.The vehicles relied on for mobile glucose management in gestational diabetes mainly included APPs,remote monitoring systems,professional websites,and social platforms,which could provide health education,glucose management monitoring and recording,social support,and glucose management follow-up and reminders to pregnant women.Most of the studies focus on the glucose index and drug use,pregnancy outcome,self-management,quality of life,user experience and resource cost of pregnant women.Conclusion Mobile glucose management carriers are geographically specific and have a positive effect on glucose control in gestational diabetes.Future studies need to further develop localized mobile glucose management intervention protocols and conduct more high-quality randomized controlled studies to verify their effectiveness.
