Objective To investigate the relationship between Lys198Asn and Taq Ⅰ polymorphisms of endothelin-1 gene and essential hypertension in Chongqing residents.Methods Polymorphisms of Lys198Asn and TaqⅠ were detected in the blood samples from 86 patients with essential hypertension(HT) and 138 normotensive controls(NT) by sequence specific primer-polymerase chain reaction(SSP-PCR) and PCR-restriction fragment length polymorphism(PCR-RFLP).Results In the BMI

The online and offline hybrid teaching model of evidence-based medicine (EBM) is currently in the stage of development. Previous teaching focused on the teaching process in the classroom, and did not organically combine all the course contents before, during, and after class. The BOPPPS model can be used to establish coherence and integrity in the EBM teaching process. Considering the discipline characteristics and teaching objectives of EBM, this study initially explored and designed a BOPPPS-based online and offline hybrid teaching model. Taking the "diagnostic evidence" module as an example, the teaching implementation details were introduced. A pre-designed questionnaire was used to conduct baseline survey and follow-up survey on students before and after class to evaluate the teaching model and effect. The surveys showed that half of the students (77/154) preferred the new online and offline hybrid teaching model of EBM. The students found that all aspects of BOPPPS teaching were generally acceptable and satisfactory. Compared with before teaching, the students' proficiency in EBM was significantly improved after the teaching ( P<0.001), particularly in their ability to retrieve literature and evaluate the quality of evidence, which is of great significance for expanding their knowledge and clinical thinking.
