Objective To explore the effect of anti-TNF rcMAb in the treatment of patients with rheumatoid arthritis (RA) and its effect on peripheral blood Th1,Th17 and Treg cells.Methods Fifty rigorously screened RA patients were randomly divided to the therapy group (n=40) who received the combined treatment of anti-TNF rcMAb and MTX,and control group (n=10) who were given MTX along with placebo,both at week 0,2,6,and 14.The clinical data of the two groups were observed and accessed respectively at week 0 and 18.In addition,the percentage of Th1,Th17,Treg cells in the peripheral blood and the relative gene expressions of transcription factors T-bet,RORC,Foxp3 in these patients were also observed respectively before and after treatment.We used t inspection and x2 inspection as the statistical analysis methods in conducting this study.Results Comparing with the control group,more patients achieved ACR20,ACR50 and ACR70 response in the combined therapy group (Z=1.671,P=0.000 94).The percentage of peripheral blood Th1 cells decreased [week 0:(7.1±3.9)％; week 18:(4.2±2.8)％] and the percentage of Treg cells obviously increased [week 0:(1.5±0.8)％; week 18:(3.0±0.6)％,t=2.301,P=0.048] in the combined therapy recipients,while the percentage of Th1 cells fell [week 0:(9.1±3.1)％; week 18:(5.8±2.6)％] and that of Treg cells slightly increased [week 0:(1.2±0.6)％; week 18:(2.2±0.6)％] in the controls.The mRNA expressions of RORC and T-bet,the transcription factors of Th17 and Th1,were decreased respectively and that of Foxp3,the transcription factor of Treg,were elevated in both groups.Conclusion The combined therapy of anti-TNF rcMAb and MTX is very effective in RA patients.Good outcome is likely achieved by modifying the peripheral blood Th cell subsets in patients with RA.

To overcome the impact of COVID-19 on medical education, School of Medicine of Shanghai Jiao Tong University reconstructed the medical teaching team under the mode of online medical education. Through the reconstruction of online teaching team and the implementation of full coverage of teaching incentives, the teaching pressure of teachers has been eased, students' autonomous learning and personalized training have been promoted, teachers' ability of information-based teaching and professional development level have been improved, and a new position of moral education has been opened up. The medical teaching team under the online teaching mode ensures the teaching quality, and also brings the possibility of multi-dimensional innovation and reform for the future development of education, which meets the actual needs of the current integration of curriculum teaching reform and development in medical colleges.

Objective Rheumatoid arthritis (RA) is a systemic autoimmune disease, which mainly involves joints across the body, resulting in joint stiffness and loss of daily activity. Recent evidence suggests that numerous self-reacting T cells, including Th1 and Th17, infiltrate the synovium in RA patients, accompanied by functionally-compromised Treg. Iguratimod, a new small molecule with anti-inflammatory and immunomodulatory effects, has shown curative effects in animal models of arthritis. In this study, we aimed to test the clinical effects of Iguratimodˊs on RA patients and its role in immunoregulation. Methods We examined the clinical effects of iguratimod on RA patients in a random controlled clinical trials and analyzed its effects on Th1, Th17 and Treg as well as their associated cytokines and transcription factors by flow cytometry and real-time polymerase chain reaction (PCR). Then t-test, chi-square test and rank sum test were used to conduct statistical analysis. Results Our results revealed that iguratimod therapy provided significantly greater clinical benefit [ACR20, ACR50, ACR70 reached 50%, 20%, 15% respectively in iguratimod treatment group, Z=-2.216,P=0.027] than placebo group with the reduction of Th1 and Th17 but increment of Treg after iguratimod treatment [Th1: week 0 (26.5 ±8.0)%, week 24 (14.2 ±7.3)%, P<0.01; Th17:week 0 (1.7±0.7)%, week 24 (1.3±0.4)%, P<0.05;Treg:week 0 (6.8±1.6)%, week 24 (8.9±2.9)%, P<0.05], which was statistically significant. Conclusion Our results provide theoretical and clinical based evidence for the impact of iguratimod on immunomodulation of RA.

The sustainable development of the teaching staff is crucial to the overall advancement of medical education reform under the background of medical and educational collaboration. With the support of the Shanghai Key Teachers' Teaching Incentive Program, Shanghai Jiao Tong University School of Medicine has established the interdisciplinary and inter-school teaching teams for undergraduate students and broken though the "last mile" of fully implementing the medical teaching reform of organ-system integrated curriculum in the country. Meanwhile, we also has reformed hourly remuneration system, formulated rules and regulations corresponding to each link, and improved the supervision mechanism, which has consolidated the mechanism of medical and educational collaboration, promoted the development of community for teachers and comprehensively improved the quality of medical education.

National education, medical industry demand and external environment all put forward the demand of training "medical + X" compound medical talents. In recent years, the development of "medical + X" has provided a foundation for the establishment of related majors in the undergraduate stage. This paper analyzes the current situation of medical interdisciplinary development at home and abroad, summarizes the existing "medical + X" training model at the undergraduate level, and argues that the new "medical + X" majors should be supported by optimizing the system design and focusing on the interdisciplinary frontier. At the same time, the setting of new majors of "Medical + X" should also pay attention to the three characteristics of livelihood, faculty and employment.

Introducing the concept of integration into medical curriculum reform is an important measure to promote the development of medical education. This research discusses the advantages and disadvantages of various teaching models by comparing the models of organ system integration courses at home and abroad, combining with the review of the development of integrated courses in Shanghai Jiao Tong University Medical College and the analysis of questionnaires from teachers and students, proposes a curriculum reform plan optimized with the concept of "Medical discipline in the new era", and puts forward targeted suggestions from the aspects of curriculum system setting, teacher security, etc., thus providing research support for the future development of organ system integration curriculum.

Shanghai Jiao Tong University established the first biomedical science in China in 2016. Learning the successful experience from international universities can promote the development of this major. According to the comparison of cultivation program and curriculum system in different top universities at home and abroad, it was showed that Oxford University focused on the pluralism development of students, University of Technology Sydney paid attention to the combination of basis and clinical practice, and the University of Hong Kong stressed the integration of clinical practice, science and research, and transformation. Through the exploration of the details of educational system this university, we found that we mainly focused on five innovation ideas: building the basic knowledge, strengthening comprehensive basic knowledge teaching, stimulating students' interests towards biomedical science, developing their ability and promoting innovative education and training. Based on analysis of those cases, it is showed that the development of biomedical science in China should solve problems in curriculum integration and practical education of science and research, so as to achieve the goal to cultivate more talents in this major and boost the development and advances in the field of biomedical science.
