Secondary osteoporosis is common in patients with early breast cancer, manifesting as low back pain, bone and joint symptoms, and osteoporotic fractures. Bisphosphonate and denosumab can reduce the incidence of fractures by minimizing bone loss, though they differ in efficacy, treatment course, and side effects. Patients should consider the pros and cons when selecting a drug. Recent studies also focus on decreasing the incidence of bone metastases. This article reviews recent advancements in the use of these two drugs for managing bone health in early breast cancer.

Objectiv To investigate an autosomal dominant non-syndromic hearing loss family pedigree com-prehensively,aiming to precisely define its clinical phenotypes and uncover the underlying molecular genetic etiolo-gy.Methods A detailed interrogation of the proband's medical history and family history was conducted.Physical examinations,audiological assessments and temporal bone CT scans were performed.Genomic DNA was extracted from the peripheral blood of the proband(Ⅳ-8)for whole-exome sequencing(WES).Subsequently,candidate vari-ants identified through WES were validated among family members using Sanger sequencing.Results There were 36 individuals in 4 generations in this family pedigree,showing autosomal dominant inheritance.Among them,16 individuals presented with progressive hearing loss.Audiological examinations were completed for 13 of them,re-vealing normal hearing in three individuals(Ⅲ-1,Ⅲ-1 1,Ⅳ-4)and bilateral symmetric hearing loss of varying se-verity in the remaining ten(Ⅱ-2,Ⅱ-4,Ⅱ-10,Ⅲ-4,Ⅲ-10,Ⅲ-13,Ⅲ-14,Ⅳ-1,Ⅳ-7,Ⅳ-8),and the degree of hearing loss was related to age.WES of Ⅳ-8 revealed that she carried the variant NM_199330.2(HOMER2):c.1064 A＞G(p.Ter354Trpext10),and Sanger sequencing verified the variation at this site.Peripheral blood samples of 18 individuals in this family were collected in total.All affected individuals(Ⅱ-2,Ⅱ-4,Ⅱ-10,Ⅲ-4,Ⅲ-9,Ⅲ-10,Ⅲ-13,Ⅲ-14,Ⅳ-1,Ⅳ-7,Ⅳ-8)carried the HOMER2 c.1064 A＞G variant,except for one young member(Ⅳ-6)who had not yet developed hearing loss.Unaffected individuals(Ⅱ-5,Ⅲ-1,Ⅲ-5,Ⅲ-11,Ⅳ-2,Ⅳ-4)lacked the variant,demonstrating complete cosegregation of genotype and phenotype.According to ACMG guide-lines,this variant was classified as likely pathogenic(PM2+PP1+PM4).Conclusion The c.1064 A＞G(p.Ter354Trpext10)variant of the HOMER2 gene is the molecular genetic etiology of this hereditary deafness family pedigree.

Objective:To evaluate the value of ultrasound radiomics combined with machine learning for early diagnosis of seronegative Hashimoto’s thyroiditis (SN-HT) .Methods:This retrospective study included 164 patients from Liaoning Provincial People’s Hospital , Lixin County People’s Hospital, Linghai Dalinghe Hospital, Fengcheng Phoenix Hospital, who underwent thyroidectomy for solitary nodules with normal thyroid function between Nov. 2016 and Jan. 2024. Postoperative pathology confirmed Hashimoto’s thyroiditis (HT) in some cases, who were further categorized into antibody-positive and antibody-negative groups based on serum antibody status. Patients without Hashimoto’s thyroiditis served as the control group. A total of 298 ultrasound images were analyzed. Radiomics features were extracted from hypoechoic non-nodular areas within 0.5 cm surrounding the tumor. Two senior pathologists and two senior ultrasound physicians independently assessed lymphocytic infiltration, eosinophilic changes of follicular epithelium, and the proportion of hypoechoic areas in pathology and ultrasound images, respectively. A machine learning model, CCH-NET, was developed using linear regression and t-distributed stochastic neighbor embedding (t-SNE) techniques. The dataset was divided into a training set (80%) and a validation set (20%) to compare the diagnostic accuracy of CCH-NET with that of senior ultrasound physicians. Results:In internal validation, CCH-NET achieved a diagnostic accuracy of 88.89% for both antibody-positive and antibody-negative groups, significantly higher than the 66.67% accuracy of senior ultrasound physicians ( P<0.01). In external validation, CCH-NET achieved 75.00% and 66.67% accuracy for the two groups, compared to 50.00% by senior ultrasound physicians. For the control group, both methods achieved 93.33% accuracy. The AUC of CCH-NET was 0.848, outperforming senior ultrasound physicians (0.681) ,demonstrating superior diagnostic performance. Conclusion:The radiomics-based CCH-NET model, using non-nodular hypoechoic areas as a specific indicator, can accurately identify early SN-HT in euthyroid patients. It significantly outperforms senior ultrasound physicians, improving diagnostic accuracy and reducing missed diagnoses.

Objective:To understand the current status of financial management in public hospitals of Anhui Province and provide a basis for strengthening financial management and promoting high-quality development in public hospitals.Methods:Stratified and random sampling methods were used to select 100 public hospitals as sample hospitals.A self-designed questionnaire was used to conduct a questionnaire survey on the current status of financial management.Results:The overall financial management level of public hospitals in Anhui Province needs to be further improved.The main problems are that the functions of the chief accountant need to be fully exerted,the structure of financial personnel is uneven,the coverage and depth of budget management are insufficient,cost accounting is relatively rough,the operation management system is not sound,the construction of internal control emphasizes form over substance,and the informatization construction needs to be advanced urgently.Conclusion:In response to the existing problems,efforts can be made from fully exerting the functions of the chief accountant,optimizing the talent team,promoting the refinement of budget and cost management,deeply carrying out operation management,improving internal control,and making up for the shortcomings of informatization,to adapt to the new situation and policy requirements of the medical industry's development.

This study aims to screen the diagnostic biomarkers for fecal antigen of Echinococcus granulosus(E.granulosus)in dogs with high specificity and sensitivity.The sheep-derived EgPSC artificially infected dogs were collected,and the negative and positive fecal samples of dogs with E.granulosus were prepared by arecoline hydrobromide leakage method.Polyclonal antibody,negative fecal antigen-polyclonal antibody conjugates and positive fecal antigen-polyclonal antibody conju-gates were purified by ammonium sulfate precipitation and affinity chromatography,three groups of samples were detected by ELISA and Western blot,LC-MS/MS and bioinformatics analysis were performed on the three groups of samples.The positive fecal antigen-polyclonal antibody con-jugate was used as the treatment group,the polyclonal antibody and the negative fecal antigen-polyclonal antibody conjugates were used as the control groups to screen the unique peptides of the treatment group.ELISA and Western blot showed that only the positive fecal antigen-polyclonal antibody conjugates were positive.According to LC-MS/MS and bioinformatics analysis,11 unique peptides were screened out only in the treatment group.Among them,3 proteins were related to E.granulosus,namely dysferlin,integrator complex 9 and diagnostic antigen gp50,which were mem-brane-associated proteins,INT complex components and diagnostic antigens.This study has pre-liminarily screened out three candidate canine E.granulosus fecal antigen diagnostic markers,pro-viding a reference for further exploration of diagnostic standards for E.granulosus,screening of echinococcosis target genes,and vaccine development.

Objective:To verify the efficacy of VELscope autofluorescence examination technology in the early warning of potential oral malignant diseases.Methods:80 patients with suspected dysplasia were included and underwent oral examination,visually en-hanced lesion scope(VELscope)autofluorescence examination and histopathology examination respectively,the fluorescence imaging results were compared with the histopathological results.Results:Pathological reports showed 64 cases with mild or no dysplasia,9 cases with moderate or severe dysplasia,1 case with moderate dysplasia without malignant transformation and 6 cases with cancer.The results of VELscope showed that there were 73 positive cases and negative 7 cases of fluorescence deletion.The sensitivity and specificity of VELscope were 93.75％and 9.37％respectively,and the sensitivity could reach 100％in the cancerous tissue.Con-clusion:As a non-invasive examination method,VELscope is highly sensitive but lowly specific.
