Objective:To explore the effectiveness of E-Coach health education in patients with acute myocardial infarction (AMI) after percutaneous coronary intervention (PCI) .Methods:A total of 112 patients with AMI admitted to the Second Affiliated Hospital of Wenzhou Medical University between January and December 2023 were selected using convenience sampling. Using a random number table, the patients were assigned to a control group ( n=56) and an intervention group ( n=56). The control group received modified cardiac rehabilitation, while the intervention group received E-Coach health education in addition to the same rehabilitation protocol. Cardiac function, ability of daily living, and self-management ability were compared between the two groups before and after the intervention. Results:After 3 months of intervention, the intervention group had a higher left ventricular ejection fraction and lower left ventricular end-diastolic and end-systolic dimension compared to the control group, and the differences were statistically significant ( P<0.05). In addition, the Barthel Index and all dimensions of the Self-management Scale scores were higher in the intervention group than in the control group after 3 months of intervention, and the differences were statistically significant ( P<0.05) . Conclusions:E-Coach health education can improve cardiac function, daily living ability, and self-management ability in patients with AMI after PCI.

Objective To establish a recurrence risk prediction model for meningioma based on HOXA9 DNA methylation.Methods Meningioma-related datasets were downloaded from GEO database for screening homeobox genes(HOXs)with prognostic values using differential methylation and ROC curve analysis and Cox regression analysis.The differentially methylated CpG sites with high predictive efficacy were selected to establish the risk prediction model using Lasso-Cox regression analysis,based on which the patients were divided into high-and low-risk groups by the cutoff value.The methylation levels of CpG sites were verified at the cell and tissue levels using methylation-specific PCR(MS-PCR).Clinical meningioma tissue samples were used to validate the predictive efficacy of the model.Results HOXA9 methylation level was significantly up-regulated in meningiomas(P<0.001)and showed a high diagnostic efficiency(AUC=0.884)as an independent risk factor for overall survival(P<0.01)positively correlated with the degree of malignancy and poor prognosis of meningioma(P<0.05).Risk stratification by HOXA9 methylation was more accurate than WHO grading for predicting recurrence and patient survival time.The AUCs of the sites cg03217995 and cg21001184 were both above 0.8 for meningioma diagnosis and above 0.6 for predicting recurrence.The patients'clinical characteristics differed significantly between the high-and low-risk groups(P<0.001),and the prediction score of the model was an independent prognostic factor for meningioma(P<0.05).MS-PCR results showed that the methylation levels of the two sites increased significantly in meningioma cells.In clinical samples,the combined model showed a high prediction efficiency(AUC=0.857),and the predicted risk of progression was highly consistent with the patients'actual condition.Conclusion High HOXA9 methylation level is a predictor for poor prognosis of meningiomas,and the combined prediction model based on its CpG sites provides a new approach to early screening of meningioma patients at risk of progression.

Objective To observe the incidence of spontaneous clearance of hepatitis B virus (HBV) DNA in chronic hepatitis B (CHB) patients ,and to investigate the related factors of the spontaneous clearance of HBV DNA and to determine the time to start antiviral therapy .Methods Patients who met the inclusion criteria were recruited from the follow-up cohort of chronic HBV infection from January 2008 to August 2017 for observation .The liver function including alanine aminotransferase (ALT) levels ,HBV DNA load and serum markers of HBV were measured at baseline ,month 1 ,month 3 and month 6 of follow-up . Evaluation index included cumulative HBV DNA negative conversion rate and cumulative HBeAg negative conversion rate .Multivariable analysis was used to analyze the factors associated with the spontaneous clearance of HBV DNA .Results A total of 116 patients were recruited in this study .All the patients showed ALT level elevation at baseline .Without antiviral treatment ,the cumulative HBV DNA negative conversion rate was 12 .9％ after 6-month observation .HBeAg negative conversion rate was 22 .5％ .Multivariable analysis showed that patients without a family history of HBV infection ,baseline ALT level >3 times the upper limit of normal (ULN) and HBV DNA level <6 lg copies/mL had higher cumulative HBV DNA spontaneous clearance rate .HBV DNA negative conversion rate in patients whomet all the above three conditions was up to 75％ .Conclusions In CHB patients and ALT level elevation for the first time , some patients could achieve spontaneous clearance of HBV DNA without antiviral therapy .Patients without a family history of HBV infection ,baseline ALT level >3 ULN and HBV DNA level <6 lg copies/mL have higher rate of cumulative HBV DNA spontaneous clearance .
