Objective:
To investigate the expression of programmed death-1 (PD-1) in liver tissue and its association with liver pathology in patients with autoimmune hepatitis (AIH).
Methods:
A total of 54 AIH patients (38 in the active stage and 16 in the remission stage) were enrolled, and 9 healthy volunteers were enrolled as control group. Immunohistochemistry combined with quantitative image analysis was used to measure the expression of PD-1 in liver tissue. The t-test, rank sum test, one-way analysis of variance, least significant difference t-test, Mann-Whitney U test, and Pearson relation analysis were used for statistical analysis of different types of data.
Results:
The AIH group had a significantly higher positive rate of PD-1 in liver tissue than the control group (13.57%±6.84% vs 2.22%±0.66%,

Objective:To understand the results of blind evaluation of dissertation of three-year doctors and eight-year medical doctors, and to explore the improvement measures of eight-year program education.Methods:The data analysis method was manipulated. A total of 47 eight-year doctoral and 88 three-year doctoral dissertations submitted by the first clinical college of Huazhong University of Science and Technology in 2020 were selected as the research material. SPSS 17.0 was used to perform Chi-square test to compare the itemized evaluation opinions of the dissertation, Spearman test was used to analyze the correlation between the defense opinions, itemized evaluation opinions and the overall evaluation.Results:The gap between eight-year and three-year doctoral dissertation is mainly manifested in innovation and research value ( χ2=9.10, P=0.003), topic and review ( χ2=5.70, P=0.017), while there is no significant difference in the overall assessment and oral defense suggestion. The main influencing factor of dissertation defense suggestion for both doctors was the dissertation standardization (eight-year: r s=0.53, P<0.001; three-year: r s=0.45, P<0.001). The evaluation results of eight-year doctor dissertation were closely related to basic knowledge and scientific research ability ( r s=0.74, P<0.001). Conclusion:There is no significant difference between eight-year doctors and full-time doctors in research attitude. But there was a certain gap in scientific research and innovation ability among them. It is suggested to clarify the teaching objectives, formulate and refine the evaluation system of dissertations, and strengthen the cultivation of scientific research interest and academic belief of eight-year study program.
