ABSTRACT
Taking the micro-course The Connection Between Vertebrae as an example, this paper discusses the teaching design, production process and practical application of the anatomy micro-course, analyzes the existing problems and puts forward corresponding suggestions. The micro-course design integrates knowledge points with ideological and political elements, and applies a variety of teaching methods to make the teaching content interesting, enlightening and applicable. In the production process, using anatomical specimens, models and 3D software demonstration structure can make abstract knowledge intuitive and perceptual. Moreover, the artistry of micro-course is increased appropriately, and the misunderstanding of emphasizing appearance and neglecting design is avoided. The application of micro-course integrates the micro-course and online education platform to realize the intelligent education of information teaching. In addition, college teachers should improve the awareness of micro-course production and carry out systematic construction and application of micro-course resources.
ABSTRACT
During the outbreak of coronavirus disease 2019 (COVID-19), combining clinical "5+3" integrated students' characteristics and the contents of the courses, teachers applied the Zhihuishu platform and Tencent classroom in anatomy theory teaching to construct an efficient, accurate and interactive online flipped intelligent classroom covering before class -in class -after class. The ARCS (attention, relevance, confidence, satisfaction) motivation model was introduced into the teaching design to help ensure the effective implementation of flipped classroom. Before class, teachers used the Zhihuishu platform to publish learning resources which students can learn independently. In class, teachers used Tencent classroom for live teaching, to explain key and difficult points, and answer and discuss questions. After class, teachers used the Zhihuishu platform to publish exercise tests and assignments. The practice shows that the online teaching mode has been widely recognized by the students. It's helpful to cultivate the learning interest, improve the ability of autonomous learning and the ability of analyzing and solving problems. It also contributes to the implementation of the diversified formative assessment, and it lays a foundation for developing the mixed teaching after the epidemic.

ABSTRACT
<p><b>OBJECTIVE</b>To investigate the effects of thoracic epidural blockade (TEB) on plasma fibrinogen (FIB) levels.</p><p><b>METHODS</b>Thirty cases of dilated cardiomyopathy (DCM) were selected randomly into a TEB group and a control group. TEB patients were subjected to a persistent TEB (T1 - 5), and injected with 0.5% lidocaine 3 - 5 ml every two or four hours for four weeks in addition to routine medicine, while patients in the control group were given routine medicine only. Plasma concentrations of FIB were measured using the micro-capillary assay. Doppler echocardiography was performed before and after the treatment.</p><p><b>RESULTS</b>Plasma concentrations of FIB in two groups were greater than the normal value before the treatment. There was a significant decrease of plasma concentrations of FIB in the TEB group after the treatment (4.2 +/- 1.3 g/L vs 3.6 +/- 0.9 g/L, P < 0.05), but there was no significant change in the control group (4.2 +/- 1.2 g/L vs 4.3 +/- 1.9 g/L, P > 0.05). After four weeks of treatment, the left ventricular end diastolic diameters (LVEDD) of TEB patients were reduced (72 +/- 10 mm vs 69 +/- 10 mm, P < 0.05) and the left ventricular ejection fraction (LVEF) of TEB patients increased significantly (33% +/- 13% vs 44% +/- 14%, P < 0.05). In contrast, LVEDD (73 +/- 11 mm vs 73 +/- 12 mm, P > 0.05) and LVEF (32% +/- 14% vs 33% +/- 12%, P > 0.05) did not change significantly in the control group.</p><p><b>CONCLUSIONS</b>The results suggest that plasma FIB levels in patients with DCM were decreased by performing a TEB, in addition to a reduction of the enlarged cardiac cavity and an improvement in cardiac systolic dysfunction. TEB might contribute to lowering the occurrence of thrombus and thromboembolism in patients with DCM. TEB might be a promising therapeutic method to improve the prognosis of DCM patients.</p>
