Objective:To evaluate the cost-effectiveness and impact on mortality of health management services for the elderly aged 65 years and older in national essential public health service project.Methods:Based on the data of county-level medical institutions in Henan Province from 2019 to 2024,the Random Forest Method was used to construct a counterfactual framework to predict the hospitalization expenses under the unmanaged scenario,and then the cost-benefit ratio(BCR)and net income were calculated.Time-dependent Cox proportional hazards model was used to evaluate the effect of health management on all-cause mortality and cardiovascular and cerebrovascular disease mortality in the elderly.Results:A total of 962 955 elderly patients were included,451 119(46.85%)were included in the management group.The average hospitalization cost of the management group was significantly lower than that of the non-management group(P<0.05).Except for 2020-2021,BCRS in 2019 and 2022-2024 were 6.34,2.05,4.45 and 6.60,respectively.The risk of all-cause death was reduced by 76.96%,and the risk of cardiovascular and cerebrovascular death was reduced by 75.57%in the elderly patients included in the management group compared with those not included in the management group.Suggestions:It is necessary to establish a health outcomes-based evaluation system and promote the transformation and upgrading of the service model from single chronic disease management to"integrated health services with multi-disease management".

Objective:To observe the applying effect of teamwork cooperation model of encephalopathy in the clinical teaching of Neurology.Methods:Sixty undergraduate students who practiced in our hospital were randomly divided into the control group and the experimental group,with 30 students in each group.The control group was arranged for internship according to the traditional department-based model,while the experimental group was arranged according to the teamwork cooperation model of encephalopathy discipline group.The theoretical examination scores and clinical skills scores of the two groups were compared,and the Mini-Clinical Evaluation Exercise(Mini-CEX)scale was used for dual evaluation by teachers and students from seven aspects:inquiry skills,physical examination skills,humanistic care,clinical judgment,communication skills,organizational effectiveness,and overall clinical competence.Result:There were statistically significant differences between the experimental group and the control group in theoretical examination scores,clinical skills scores,and dual evaluation by teachers and students(P＜0.05).Conclusion:Compared with the traditional teaching model,the teamwork cooperation model of encephalopathy discipline group has achieved better results in the clinical teaching of Neurology.

Purpose To investigate the correlation between molecular typing of urothelial carcinoma(UC)and its clinicopathologic features and prognosis,in order to explore the prognostic markers and therapeutic targets for UC.Methods 115 patients with UC were retrospectively analyzed.Immunohistochemical markers GATA-3,CK20,CK5/6 and CD44 were used for molecular typing of UC(luminal-like type,basal-like type and null).Correlations between molecular typing and clinicopathological features were analyzed using the Chi-square test and Fisher precise test.Sur-vival analysis was performed using the Kaplan-Meier test and Log-rank test.Results The expression of GATA-3 and CK20 was negatively correlated with the clinical stage of UC,while the expression of CD44 was positively correlated with the clinical stage of UC(both P＜0.05).CK20 was a marker of good prognosis(P=0.03).The proportion of clinically advanced UC with basal-like type was significantly higher than that of luminal-like type(78.4％vs 53.4％,P=0.033).Among the histologic variants,UC with neuroendocrine differentiation(100％),sarcomatoid carcinoma(80.0％)and squamous differentiation(77.8％)were basal-like type.All plasmacytoid and lymphoepithelioma-like types,as well as 81.8％of micropapillary UC.Among the null phenotypes,the differential variant predominated(66.7％).Compared with the luminal-like type,although the prognosis of basal-like UC was worse,there was no sta-tistically significant difference(P＞0.05).Conclusion Patients with CK20-expressing UC had a significantly better prognosis.The main histologic variants types of basal-like type and coelomofacial type are different.Molecular typing of UC using immunohistochemical markers is suggestive of clinical staging and prognosis of patients.

Purpose To investigate the relationship between the expression of POSTN and NECTIN-3 in urothelial carcinoma(UC)and its clinicopathologic features and prognosis.Methods Clinical data of 115 UC patients were col-lected.EnVision two-step method was used for immunohistochemical analysis to determine the expression of POSTN and NECTIN-3 in UC and their correlation with clinicopathological features and prognosis.Transcriptomic data from TCGA database were used to analyze the correlation between the expression of POSTN and NECTIN-3 in bladder cancer and the pathological stage and prognosis of bladder cancer.qPCR and Western blot were used to detect the expression levels of POSTN and NECTIN-3 in tumor tissues and adjacent tissues of patients.Results TCGA database analysis showed that the expression level of NECTIN-3 in urinary bladder urothelial carcinoma(UBUC)was significantly lower than that in paracancer tissues,and POSTN expression was positively correlated with pathological stage.Prognostic a-nalysis showed that POSTN expression was negatively correlated with the overall survival of UBUC(P＞0.05),and NECTIN-3 expression was negatively correlated with disease-free survival of UBUC(P＞0.05).The experimental re-suits showed that patients with positive POSTN expression were more prone to perineural invasion[25 cases(86.2％)vs 4 cases(13.8％),P=0.019],vascular invasion[36 cases(83.7％)vs 7 cases(16.3％),P=0.007],and lymph node metastasis[24 cases(88.9％)vs 3 cases(11.1％),P=0.033].Additionally,the positive expression rate of POSTN in UBUC was significantly higher than that in upper tract urothelial carcinoma(UTUC)(75.0％vs 54.3％,P=0.028).Higher expression levels of POSTN and NECTIN-3 were associated with shorter overall survival,but the difference was not statistically significant(P＞0.05).Conclusion There is no significant correlation between NECTIN-3 and the clinicopathological features and prognosis of urothelial carcinoma,while the expression of POSTN is correlated with the invasive clinicopathological features of UC,which has certain suggestive significance for clinical stage and prognosis.

Objective To examine the effect and electrophysiological mechanism of repetitive transcranial magnetic stimulation(rT-MS)augmentated to group cognitive training(GCT)on children with high-functioning autism spectrum disorder(ASD)comorbided with attention-deficit/hyperactivity disorder(ADHD).Methods From March to December,2023,70 children diagnosed with ASD+ADHD were recruited from the Affiliated Xuzhou Children's Hospital of Xuzhou Medical University and partnering special education centers.They were randomly divided into control group(n=35)and experimental group(n=35).Both groups received standard-ized GCT,twice a week,for ten weeks.During the same period,the control group received sham stimulation,while the experimental group additionally received 1 Hz rTMS over the right temporoparietal junction at 80%of resting motor threshold,five times a week,for ten weeks.Core symptoms were assessed before and after treat-ment with the Social Responsiveness Scale-2(SRS-2),Repetitive Behavior Scale-Revised(RBS-R)and Conners Parent Rating Scale-3(CPRS-3)attention-deficit and hyperactivity/impulsivity subscales.Resting-state EEG was simultaneously recorded to obtain θ and β power spectral density(PSD)and the θ/β ratio at Fz,Cz and Pz.Results Two cases in the control group and one in the experimental group dropped down.After treatment,SRS-2 scores(|Z|>4.876,P<0.001)and RBS-R scores(|Z|>4.329,P<0.001)decreased in both groups.CPRS-3 attention-deficit scores(|Z|>4.940,P<0.001)and hyperactivity/impulsivity scores(|t|>16.273,P<0.001)decreased in both groups,and they were lower in the experimental group(Z=4.732,P<0.001;t=-3.169,P<0.01).In the experimental group,Fz θ-PSD decreased significantly(Z=-4.830,P<0.001),and it was lower than that in the control group(Z=-2.609,P=0.009);and the θ/β ratio likewise fell(t=4.754,P<0.001),and it was lower than that in the control group(t=-2.256,P=0.027).Conclusion Adding rTMS to GCT can further alleviate attention deficits and hyperactive-impulsive symptoms in chil-dren with ASD comorbided with ADHD,which may associate with the inhibit of power of θ wave in profrontal contex.

Objective:To investigate the clinicopathological features and differential diagnosis of male genital system lympho-ma(MGSL).Methods:We retrospectively analyzed the clinicopathological and immunophenotypic features and prognosis of 80 ca-ses of MGSL.Results:The onset age of the MGSL patients ranged from 4 to 85(median 62)years old.All the cases showed non-specificity of the imaging features and clinical manifestations.MGSL was located mainly in the testis(n=66),followed by the pros-tate(n=7),epididymis(n=3),scrotum(n=3)and penile glans(n=1).Diffused large B cell lymphoma(DLBCL)was the most common pathological type(n=62),next came extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue(MALT)(n=7)and other rare types(n=12).During the 1-112-month follow-up of 10 of the 19 patients,1 died at 1 month af-ter diagnosed with prostatic B-lymphoblastic lymphoma(B-LBL)and another 1 died at 50 months after diagnosed with testicular DLBCL.Conclusion:MGSL is rare clinically,mainly of the DLBCL type pathologically,lacking specificity in clinical symptoms and imaging manifestation.The definite diagnosis of the malignancy depends on histopathology combined with related molecular exami-nation and immunohistochemical labeling,and R-CHOP chemotherapy is the first choice for its treatment.

OBJECTIVE To investigate the ameliorative effect and potential mechanism of imperatorin(IMP)on doxorubicin(DOX)resistance in breast cancer.METHODS The effects of maximum non-toxic concentration(100 μg/mL)of IMP combined with different concentrations of DOX(12.5,25,50,75,100 μg/mL)on the proliferation of MCF-7/DOX cells were determined by MTT method.MCF-7/DOX cells were divided into blank control group(1‰ dimethyl sulfoxide),DOX group(50 μg/mL),IMP+DOX group(100 μg/mL IMP+50 μg/mL DOX)and IMP group(100 μg/mL).mRNA and protein expressions of multidrug resistance protein 1(MDR1)and multidrug resistance-associated protein l in each group were measured.The relevant pathways and targets involved in the improvement of DOX resistance in breast cancer cells by IMP were screened and validated by using transcriptome sequencing technology,along with gene ontology(GO)enrichment analyses and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analyses.RESULTS Compared with DOX alone,the combination of IMP and DOX reduced the half inhibitory concentration of DOX on MCF-7/DOX cells from 81.965 μg/mL to 43.170 μg/mL,the reverse fold was 1.90,and the mRNA expression of MDR1 was significantly down-regulated(P＜0.05).The results of GO enrichment analyses and KEGG pathway enrichment analyses indicated that the reversal of DOX resistance in breast cancer by IMP was mainly associated with the regulation of biological processes such as detoxification,multiple biological processes,and cell killing.The main pathway involved was the p53 signaling pathway,and the key targets mainly included constitutively photomorphogenic protein 1(COP1),cyclin E1(CCNE1),growth arrest and DNA damage-inducible protein 45A(GADD45A)and GADD45B.The results of the verification experiments showed that compared with DOX group,there was a trend of up-regulation of COP1 mRNA,and significant down-regulation of CCNE1,GADD45A,and GADD45B mRNA expression in IMP+DOX group(P＜0.05).CONCLUSIONS The effect of IMP in ameliorating DOX resistance in breast cancer is related to its regulation of COP1,CCNE1,GADD45A and GADD45B targets in the p53 signaling pathway.
