Objective:To systematically evaluate the current status of research on the development of indicators for entrustable professional activities (EPAs) of residents in China.Methods:We searched the China National Knowledge Infrastructure, Wanfang Data, Airiti Library, PubMed, Embase, and Web of Science databases for literature on the development of EPA indicators for residents in China published between January 1, 2005 and February 28, 2025. Two researchers independently screened the literature and extracted data, followed by descriptive analysis. The quality of the studies was assessed using the Joanna Briggs Institute critical appraisal tool for expert opinion. Quantitative data were presented as medians (ranges) and qualitative data were presented as frequencies (percentages).Results:A total of eight articles were included, in which two general EPA indicator systems and six specialty-specific EPA indicator systems were developed for residents. The overall quality of the research was high, with the main shortcomings related to the methods used in the process of constructing the consensus indicators. The number of experts recruited ranged from 22 to 45, with 100.00% response rate, high authority coefficients (0.820-0.914), and high coordination coefficients (0.157-0.741). Most of the studies used literature reviews as one source for the indicator pool (8 studies, 100.00%), employed the Delphi method to reach consensus (6 studies, 75.00%), and provided inclusion criteria for the indicators (7 studies, 87.50%). However, only one study (12.50%) explored the practical application of the developed indicators, and none of the studies set indicator weights or conducted quality assessments. The number of EPA indicators developed ranged from 10 to 38 per study. The reporting of EPA indicators was included in most studies regarding titles (8 studies, 100.00%) and the expected levels of entrustment at various stages of training (6 studies, 75.00%), but the reporting on other aspects was lacking. Among the specialty-specific EPA indicators, 38.39% overlapped with the general EPAs indicators.Conclusions:The research on the development of EPA indicators for residents in China is still in its early stages, and there is room for improvement in methodological quality and reporting coverage. There is partial overlap between specialty-specific and general EPA indicators, failing to fully reflect the unique characteristics of different specialties.

Objective:To investigate the current status of Chinese-foreign cooperative education programs for medical majors, and to discuss the potential problems and development trends of this field.Methods:Related data were collected from the information platform of Chinese-Foreign Cooperation in Running Schools by Ministry of Education of the People's Republic of China, and the characteristics of Chinese-foreign cooperative education programs for medical majors were extracted for analysis. Categorical data were expressed as frequency (percentage), and continuous data were expressed as mean±standard deviation.Results:A total of 83 Chinese-foreign cooperative education programs for medical majors were included in the study, accounting for only 3.45% (83/2 406) of all programs. Chinese partners in these cooperative programs were mainly from East China (41 programs, 49.40%), while foreign partners were mainly from Europe (39 programs, 46.99%). The mean duration of these programs was (3.61±0.88) years, with an enrollment of (87.08±35.52) students. Most of the students were included in National General Higher Education Enrollment Plan (79 programs, 95.18%), and the main majors included nursing (39 programs, 46.99%), medical technology (19 programs, 22.89%), and clinical medicine (11 programs, 13.25%), with the main enrollment level of junior college (45 programs, 54.22%). Chinese partners in the cooperative programs mainly issued academic certificate (45 programs, 54.22%) or academic certificate plus degree certificate (36 programs, 43.37%), while most foreign partners did not issue such certificates (44 programs, 53.01%).Conclusions:There are several problems in Chinese-foreign cooperative education programs for medical majors, such as a limited number of programs, a significant regional difference, an imbalanced distribution of specialties, a low level of education, and inconsistency in issuance of certificates, which still requires further improvement and standardization. However, there are also high-level and high-quality programs for reference.

Objective::This study aimed to assess the impact of proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor treatment immediately after percutaneous coronary intervention (PCI) on the myocardial salvage index (MSI) in patients with anterior ST-segment elevation myocardial infarction (STEMI) 5-10 d after the procedure.Methods::The early PCSK9 inhibitor thERapy Following pErcutaneous Coronary inTervention (PERFECT) trial is a prospective randomized controlled trial. From January 2021 to December 2023, 32 patients with anterior STEMI from Tongren Hospital, Shanghai Jiao Tong University School of Medicine, Songjiang Hospital Affiliated to Shanghai Jiao Tong University School of Medicine, and Shanghai Tenth People’s Hospital were enrolled in the PERFECT trial. Patients were randomly assigned in a 1∶1 ratio to the PCSK9 inhibitor group ( n = 16) or the control group ( n = 16), and their baseline data were collected. Patients in the PCSK9 inhibitor group (ie, alirocumab group) received a subcutaneous injection of PCSK9 inhibitor (alirocumab, 75 mg) immediately after PCI based on conventional treatment. In the control group, patients received only conventional treatment. The primary endpoint was the MSI measured by cardiovascular magnetic resonance 5-10 d after PCI. The secondary endpoints included the left ventricular ejection fraction measured by cardiovascular magnetic resonance 5-10 d after PCI and the time to peak of creatine kinase isoenzyme-MB and high-sensitivity cardiac troponin T. Safety endpoints included any clinical adverse events that occurred during the 6-month follow-up period. Results::Baseline data during admission showed no intergroup significance. No significant difference in MSI (55.54% ± 14.80% vs. 44.72% ± 15.42%, P = 0.056) and left ventricular ejection fraction (51.24% ± 8.91% vs. 44.99% ± 8.84%, P = 0.060) was observed. Additional, there was no significant difference in the time to peak of creatine kinase isoenzyme-MB ((12.97 ± 5.67) h vs. (14.31 ± 7.04) h, P = 0.557) and high-sensitivity cardiac troponin T ((21.03 ± 12.46) h vs. (21.44 ± 9.99) h, P = 0.920) between the 2 groups. During the 6-month follow-up period, only 1 patient in the PCSK9 inhibitor group developed cerebral hemorrhage 6 months after PCI. Conclusions::Early treatment with alirocumab did not exhibit a significant increase in MSI at 5-10 d in patients with anterior STEMI. Larger trials are necessary to evaluate the impact of early administration of PCSK9 inhibitors after myocardial infarction.

This paper aims to discuss the ideas and experience about the radiology residency training system of Canada with a presentation of its base accreditation standards for five aspects, competency goals for seven roles, four stages of training arrangement, and two types of final assessment questions. Although the Canada's radiology residency program differs from China's standardized resident and specialist training programs for radiology, there are still several points that are worth referencing, including emphasizing the training priority of competency goals, providing a specific basis for the stratification of training, offering clear guidance for the implementation of training content, and improving assessment methods to focus on competency goals. These points are of great value for improving the standardized radiology resident and specialist training programs in China, so as to provide a reference for the training of excellent radiologists in China.

The Brodmann area(BA)-based map is one of the most widely used cortical maps for studies of human brain functions and in clinical practice;however,the molecular architecture of BAs remains unknown.The present study provided a global multiregional proteomic map of the human cerebral cortex by analyzing 29 BAs.These 29 BAs were grouped into 6 clusters based on similarities in proteomic patterns:the motor and sensory cluster,vision cluster,auditory and Broca's area cluster,Wernicke's area cluster,cingulate cortex cluster,and heterogeneous function cluster.We identified 474 cluster-specific and 134 BA-specific signature proteins whose functions are closely associated with specialized functions and disease vulnerability of the corresponding clus-ter or BA.The findings of the present study could provide explanations for the functional connec-tions between the anterior cingulate cortex and sensorimotor cortex and for anxiety-related function in the sensorimotor cortex.The brain transcriptome and proteome comparison indicates that they both could reflect the function of cerebral cortex,but show different characteristics.These pro-teomic data are publicly available at the Human Brain Proteome Atlas(www.brain-omics.com).Our results may enhance our understanding of the molecular basis of brain functions and provide an important resource to support human brain research.

Objective To investigate the relativity between c.553G/T polymorphism in exon 4 of Apolipoprotein A5 gene and hypertriglyceridemia (HTG) in Zunyi Han Nationality. Methods c.553G/T polymorphism of 103 HTG patients and 165 healthy individuals were tested by polymerase chain reaction and restriction fragment length (PCR-RFLP) assay. The distributions of genotypes and allele frequencies in HTG patients and healthy group were analyzed between Zunyi population and others. Results The genotype frequency of the Apo A5 gene c.553G/T showed statistical difference between patients group and normal groups (P < 0.05). The distribution of ApoA5 c.553T gene in HTG was higher than the normal group significantly (P < 0.05), and it had effect on triglyceridemia level independently (OR = 15.768, 95%CI: 5.916 ~ 42.025, P < 0.001). In the normal Han nationality groups, gene frequency of Zunyi was lower than that in Taiwan, Jiangsu and Hubei (P < 0.05), but similar to that in Hunan and Xinjiang (P > 0.05). In HTG groups, gene frequency of Zunyi was similar to that in Jiangsu (P>0.05), but higher than that in Xinjiang (P<0.05) and lower than that in Taiwan (P > 0.05). Conclusion There is relativity between Apo A5 gene c.553G/T polymorphisms and HTG in Zunyi Han nationality and the differences vary across different areas. It could be an independent risk factor for HTG.

Objective To investigate the value of multislice spiral CT(MSCT,)in interventional therapy of the hepatocellular carcinoma(HCC)emphasising on transcatheter hepanc arterial chemoembolization(TACE).Methods MSCT were performed in 60 cases of HCC before interventional procedure,CT findings of hepatic artery phase,portal venous phase and hepatic venous phase were observed respectively,among which CTA were done in 15 cases,and the anatomy of celiacartery and its branches were observed in 45 cases.The schemes of interventional therapy were worked out according to the findings of MSCT.Results MSCT showed 250 lesions,10 cases of tumor thrombosis in portal vein and 19 cases of hepatic arterioportal shunt.There was no significant difference between MSCT and digital subtraction angiography(DSA)in positive rate of in showing number of tumor or tumor thrombosis in portal vein(P＞0.05),but the 3D construction of celiac artery branches in CTA was better than that in DSA,while angles between celiac artery and abdominal aorta in MSCT were more convenient than that in DSA.MSCT showed 5 eases of hepatic artery original abnormality,according to that in DSA.Conclusion MSCT is of importance for guidance of interventional therapy of hepatocellular carcinoma.
