ABSTRACT
This study explores the application effect of the case-based teaching method based on Xuexitong learning platform in the online teaching of Digestive System, and analyzes the learner's emotional experience, learning behavior, and learning effect in the case-based online teaching. The results of the study show that the case-based online teaching model based on Xuexitong learning platform improves students' online learning interest, and the students have good emotional experience, high learning enthusiasm, good classroom interaction, enhanced self-learning ability before and after class, and good learning effect. In addition, precise teaching can be used for individual students who are not enthusiastic about online learning.
ABSTRACT
To explore the pharmacogenomic markers that affect the platinum-based chemotherapy response in non-small-cell lung carcinoma (NSCLC), we performed a two-cohort of genome-wide association studies (GWAS), including 34 for WES-based and 433 for microarray-based analyses, as well as two independent validation cohorts. After integrating the results of two studies, the genetic variations related to the platinum-based chemotherapy response were further determined by fine-mapping in 838 samples, and their potential functional impact were investigated by eQTL analysis and in vitro cell experiments. We found that a total of 68 variations were significant at P < 1 × 10-3 in cohort 1 discovery stage, of which 3 SNPs were verified in 262 independent samples. A total of 541 SNPs were significant at P < 1 × 10-4 in cohort 2 discovery stage, of which 8 SNPs were verified in 347 independent samples. Comparing the validated SNPs in two GWAS, ADCY1 gene was verified in both independent studies. The results of fine-mapping showed that the G allele carriers of ADCY1 rs2280496 and C allele carriers of rs189178649 were more likely to be resistant to platinum-based chemotherapy. In conclusion, our study found that rs2280496 and rs189178649 in ADCY1 gene were associated the sensitivity of platinum-based chemotherapy in NSCLC patients.

ABSTRACT
In order to meet the needs of social development for public health talents and optimize the curriculum system and teaching content of preventive medicine, the course of "Health Emergency" should be set up. It integrates the related content in many courses, and there are 20 hours for theory and 18 hours for experiment or practice. The course takes the emergency response as the cutting point focuses on the projects with high demand of the industry improves the platform and expands the content of emergency skill training through the extracurricular activities and special lectures. Combining theory with practice, this paper explores teaching reform measures that are conducive to improving students' core competence in public health.
ABSTRACT
Long-term medical education program requires that the medical students should ac-quire both professional knowledge and scientific research ability. These students,with heavy task and course,have difficulty in performing the scientific research systematically. It is very important to develop the early scientific research training. Department of pathology in Central South University,took early sci-entific research activities in various forms,such as literature searching,reviews writing,research design-ing,experiment performing,lecture communicating and clinical practicing after combining the discipline characteristic and arranging the overall process. Satisfactory effects were achieved with efforts.
ABSTRACT
The training of teaching ability is an important context of master course.Pathology Department of Xiang Ya School of Medicine take experimental teaching practice as the important way to improve their pathological experimental teaching skill.In this paper we introduced our experience.
ABSTRACT
Experimental teaching plays an important role in pathological teaching.We have taken effective measures to renovate the methods for experimental teaching,establishing open teaching mode.As a result,teaching quality increases and students become more active in pathological learning.
ABSTRACT
Objective To observe the expression changes of heme oxygenase-1(HO-1) and its mRNA after spinal cord injury (SCI). Methods SD rats were randomly divided into normal (n=5), control (n=5) and experimental group (n=10). The rats were given no operation in the normal group, laminectomy only in the control and both laminectomy and traumatic injury in the experimental group. The SCI animal models were made by using a modified Allen's weight-drop device (50 g.cm) on T 12 . Rats were sacrificed at 1 and 3 days after injury. The distribution and content changes of HO-1 and its mRNA in spinal cord segments were observed by means of immunohistochemistry and in situ hybridization. Results Expression of HO-1 was mainly in neurons in the normal spinal cord. After injury, HO-1 expressed primarily in astrocytes and microglia and the distribution of positive cells closely correlated with intraparenchymal hemorrhage. Protein began to increase at the first day after injury. The expression intensity and the area of positive cells were (148.26?11.39) and (90.50?8.70)?10 3 ?m 2 respectively. At the third day, protein expressed more significantly with expression intensity of (128.03? 12.59) and area of (112.99?10.01)?10 3 ?m 2. The expression intensity and area of positive cells expressed by mRNA were (106.02?9.10) and (70.05?9.26)?10 3 ?m 2 respectively at the first day after injury, (85.82?9.07) and (87.37?10.95)?10 3 ?m 2 respectively at the third day after injury. There was significant difference between experimental and control groups ( P
ABSTRACT
In order to promote the optional subjects' function in perfecting knowledge construction and developing the character of the students,through analyses of the results of 670 classmates’selection of optional subjects,we know in detail what kind of optional subjects students like and need.Therefore based on how to organize teaching and manage optional subjects we bring up the suggestions for enhancing the optional subjects ' development and management:setting students as the center and increasing optional subjects,establishing the leading teacher's system,reforming teaching method,enriching teaching means,and strengthening the management of the examination of optional subjects.
