Objective:To evaluate the effectiveness of entrustable professional activities (EPAs) in the general practice internship of undergraduate clinical medicine students, identify issues that need improvement in the internship, and enhance medical students' competence.Methods:A total of 75 students in the five-year (English class) clinical medicine program enrolled in 2018 and 2019 who participated in general practice internship in Renji Hospital affiliated to Shanghai Jiao Tong University School of Medicine from October 2021 to October 2023 were selected as study subjects. The design of core EPAs was adopted to assess the correlation among different EPA dimensions and to analyze the qualified rates.Results:The evaluation of EPAs showed that EPA2 (practicing respect, understanding and teamwork) had the highest mean score of 9.33, and EPA10 (chronic disease management and management of key populations) had the lowest mean score of 8.08. A supervision level of 3a and above was used as the criterion for qualification. The supervision levels of the students' EPAs were mostly concentrated at levels 3a and 3b. The highest qualified rate was for EPA2 (practicing respect, understanding and teamwork) at 85.33%, followed by EPA1 (complying with the rules of the profession and demonstrating professionalism) at 80.00% and EPA8 (reviewing information and solving clinical problems) at 72.00%. The lowest qualified rate was for EPA10 (chronic disease management and management of key populations) at 33.33%, followed by EPA4 (analyzing and interpreting test results) at 57.33%.Conclusions:EPAs concretize competency evaluation, which can effectively reflect the "competency-oriented" training objectives encompassing multiple elements such as knowledge, skills, values, and attitudes, while maintaining professional specificity. Undergraduates demonstrated strengths in professionalism and academics, but showed deficiencies in community chronic disease management and management of key populations. These findings suggest the need to strengthen the training in health and social care to better align with the competencies required during standardized residency training.

Objective:To investigate the pathology characteristics, so as to provide treatment experience of primary cardiac tumors for pediatric patients.Methods:A retrospective study was conducted for 135 patients with primary cardiac tumor between January 2004 and December 2017 in Shanghai Children′s Medical Center.The median age was 0.54 years (range, 0-14.36 years). Single tumor was discovered in 61 cases and multiple rumors were found in 74 cases.Forty-five patients presented obvious clinical symptoms, 4 patients with mild symptoms and 86 patients without symptoms.Forty-one patients underwent surgical treatment, including complete resection of the tumor in 24 cases, partial resection in 16 cases and heart transplantation in 1 case.Concomitant valvuloplasty was required in 13 patients.Ninety-four patients did not receive surgical treatment.Results:A total of 40 patients underwent surgical treatment in Shanghai Children′s Medical Center.Three patients died of low cardiac output (in-hospital mortality: 7.5%), and 2 patients recovered from postoperative low cardiac output.The hemodynamic status was stable in the remaining 35 cases.One patient who received heart transplantation in another hospital survived and had good cardiac function during 24 months follow-ups.There were no significant differences in the survival rate between partial resection and complete resection of benign tumors.One late death was observed in patients with malignant tumors for 2 years after operation.Surveillance was kept in 94 non-surgical patients, among whom 1 case died for the abandon of surgery and 1 case died when waiting for heart transplantation.Other 2 patients were waiting for heart transplantation and other 90 patients had no hemodynamic disorder.Conclusion:Most of primary cardiac tumors are benign and long time follow-up should be able to get on for pediatric patients.When patients develop hemodynamical obstruction, arrhythmia or malignant tumor, surgical treatment is necessary.The principle of surgical therapy in these patients is to restore normal hemodynamic status, instead of completely removing tumor.Heart transplantation is potentially the only way for patients whose tumor cannot be resected.

Objective To investigate the therapeutic effect of the transcatheter closure of antegrade pulmonary blood flow with high-risk Fontan operations.Methods Retrospective analysis of 6 Fontan surgical patients, 4 males and 2 females, who received surgical treatment in the cardiothoracic surgery of Shanghai Children's Medical Center from May 2016 to August 2018;Age(5.7 ±2.9) years;(19.8 ±5.5) kg weight.All 6 patients were treated with primary pulmonary artery banding operation and secondary bilateral Glenn operation(BDG) and re-PAB.Before Fontan surgery, cardiac catheterization was performed in the department of cardiology to close the antegrade pulmonary blood flow .Results These six patients received interventional therapy in the department of cardiology.The mean pulmonary artery pressure(Pp) before occlusion was(17.0 ±0.8) mmHg (1 mmHg=0.133 kPa), the ventricular diastolic pressure(VEDP) was (11.2 ±0.9) mmHg, and the mean pulmonary artery pressure after occlusion was effectively decreased to(14.2 ±0.7) mmHg and VEDP to(9.7 ±0.7) mmHg.Fontan surgery was performed 6 to 12 months after the occlusion.No death was found after the operation, and all the clinical indicators were normal after the operation.Follow-up was conducted for 2-24 months, and the cardiac function and the function of each organ recov-ered well.Conclusion For some patients with high risk Fontan before operation , this method can safely and effectively reduce the average pulmonary artery pressure and reduce the ventricular and pulmonary vascular load , which is of positive help for the successful Fontan operation.

Objective: To explore the surgical strategy for Ebstein anomaly in children. Methods: From January 2003 to December 2015, a total of 141 cases of Ebstein anomaly were treated at Department of Pediatric Cardiothoracic Surgery, Shanghai Children′s Medical Center, School of Medicine, Shanghai Jiaotong University. There were 65 male and 76 female patients, with age of (6.9±1.6) years (ranging from 10 months to 15 years), weight of (19.6±4.7) kg (ranging from 6.5 to 59.0 kg). All patients were diagnosed by 2 dimensional Doppler echocardiography and the septal leaflet and posterior leaflet displaced downward from 1.0 to 5.0 cm. The tricuspid valve regurgitation (TR) were mild in 26 cases, moderate in 46 cases and severe in 69 cases. Tricuspid valvuloplasty were performed in 131 cases (94 cone reconstruction, 37 valve hoist), tricuspid valve replacement in 2 cases and tricuspid valve closed in 8 cases. Surgical strategy were divided into biventricular heart function in 77 cases, one and a half ventricular heart function in 56 cases, and single ventricular heart function in 8 cases. Results: Three patients were changed to one and a half ventricular repair from biventricular repair due to unstable hemodynamics in the early postoperative period. One case died in biventricular group. The complete atrioventricular block were occurred in 3 patients and pacemaker were applied. One hundred and forty cases discharged from hospital. There were mild TR in 118 cases, moderate in 14 cases and closed in 8 cases. One hundred and thirty-seven cases were followed up regularly in 18 to 172 months. Ninety-one cases were treated by cone reconstruction (mild TR in 75 cases, moderate in 15 cases and severe in 1 case). Thirty-six cases were operated by tricuspid valve hoist (mild TR in 21 cases, moderate in 12 cases and severe in 3 cases). In the patients with severe TR (4 cases), 3 cases were reoperated by cone reconstruction. One case′s valve was closed because of the dysplasia of the anterior valve and then from one and a half ventricular heart function to single ventricular function, the oxygen saturation was increased. Two patients underwent tricuspid valve replacement, 1 died and the other′s mechanical valve was removed, and changed to single ventricular function repair. Conclusions Although tricuspid cone reconstruction can achieve good results, the stable hemodynamic of early postoperative can be effectively maintained by using the surgical strategy of one and a half ventricular repair. To the patients with severe tricuspid regurgitation and hypoxemia due to severe tricuspid valve dysplasia, transforming to a functional single ventricle may be the only choice when there comes to the unstable hemodynamic.

Objective To explore the relationship between the serum anticardiolipin antibody (ACA),vascular endothelial grow factor (VEGF) concentration and cognitive impairment in patients with ischemic stroke.Methods Totally 128 cases with acute ischemic stroke were admmitted in stroke unit ward of our hospital during June 2014 to December 2014.According to the score of Montreal cognitive assessnent (MoCA),128 patients with ischemic stroke were divided into groups A (53 cases with cognitive impairment) and group B (75 cases without cognitive impairment).The concentrations of serum ACA,VEGF were quantitatively determinated by ELISA.The differences of serum ACA,VEGF concentrations were compared between the two groups.Results Compared with normal cognitive function group,the cognitive impairment patients had significantly higher ACA concentration ((0.86±0.16) mg/L vs (0.52±0.08) mg/L,P＜0.01),and lower VEGF concentration ((197.60±7.48) pg/ml vs (205.80±8.52) pg/ml,P＜0.05).Logistic regression revealed that ACA and VEGF were independent effect factors for cognitive impairment (ACA:B =2.841,OR =0.33,95 ％ CI =0.118-0.926,P=0.025.V EGF:B =-1.674,OR =4.99,95％ CI =1.688-4.741,P=0.034).Conclusion ACA and VEGF may play an important role in cognitive impairment after ischemic stroke.

Objective To evaluate the outcome of super-selective embolization of renal artery for severe hemorrhage after percutaneous nephrolithotomy (PCNL) and its effect on renal function. Methods From May 2008 to Feb 2010,severe bleeding occurred in 7 patients after PCNL in our hospital.(5 males and 2 females,average age of 54.9 years ).All cases were treated with super-selective renal angiography and 6 cases underwent microcoil embolization. Results Renal angiography showed pseudoaneurysm in 5 cases,pseudoaneurysm with arteriovenous fistula in 1 case and no severe bleeding in 1 case.Successful coil embolization was confirmed in 6 cases by angiography,and bleeding stopped within 3 -7 days after embolization.Serum creatinine and blood urea nitrogen were 59 -98 μmol/L(mean,78.3 μmol/L) and 1.86 -6.92 mmol/L( mean,4.8 mmol/L) 2 weeks after embolization,respectively. Conclusions Super-selective embolization of renal artery for severe hemorrhage after percutaneous nephrolithotomy has the advantages of remarkable hemostatic effects and mild impaired renal function,which is of the first choice.

Objective To evaluate outcome of injection of botulinum toxin A to treat post-stroke muscle spasm under color doppler ultrasound guide. Methods 15 stroke patients following spasm in upper limb were chosen. Under the guidance of ultrasound, botulinum toxin A was accurately injected in biceps, brachialis, deep flexor muscle of fingers, superficial flexor muscle of fingers, musculus flexor carpi ulnarista, thumb-muscle, palmaris longus muscle, musculus pronator teresta, and quadrate pronator muscle. All patients went on rehabilitation training after injection. Upper limb function was evaluated by using modified Ashworth(MAS) and Fugl-Meyer scores before injenction, two weeks and four weeks after injection. Results Recovery of muscle spasm and scores of the upper limb motor function were better than that before injection.Conclusion Under color doppler ultrasound guidance, injectionof the botulinum toxin A can treat post-stroke muscle spasm with accurate location.
