Abstract： [Purpose/significance] The paper compared and analyzed the undergraduate and master education in Chinese and American universities to provide reference for future medical informatics education in China.[Method/process] Taking the opening time and college level as the selection criteria, 10 representative universities from China and the United States were selected as the research objects. Through online research, the paper comprehensively analyzed the general situation of medical informatics education in China and the United States from the aspects of basic requirements, curriculum, teacher strength, teaching methods and employment prospects.[Result/conclusion] Although China has made some achievements in medical informatics education after decades of exploration and practice, compared with the United States, China still has some shortcomings. In terms of basic requirements for admission, China mainly concentrates on the undergraduate education so that the high-level personnel training system is imperfect; in terms of curriculum, the content of courses is monotonous and the proportion of non-medical basic courses is too high, and the interdisciplinary integration is not obvious; in terms of teachers' strength, the teacher's subject background is single and the distribution of teachers' professional titles is unbalanced; in terms of education and teaching methods, the teaching methods are simple and there are fewer practical opportunities for students; in terms of employment prospects, students knowledge system is not systematic and the employment prospects are limited. Therefore, China should conform to the development requirements of the big data science research paradigm, speed up the cultivation of high-level medical informatics; improve the curriculum and content settings, broaden the scope of subject knowledge system; optimize the allocation of teachers to attract multi-disciplinary background talents; enrich training methods, and pay attention to the combination of theory and practice.

Abstract： Co-Mn alloy coatings can be prepared on 304 stainless steel with a chloride containing bath, while the effect of pH value of the electrolyte and the applied current density on the microstructure and composition of the coatings was investigated. The results indicated that the Mn content in the coatings increased with either increasing pH value or current density in a pH value range of 2.5 to 6.5 and a current density range of 125 to 225 mA/cm2 respectively. The pH value was the main factor determining the composition of Co-Mn alloys when the current density was of 125 and175 mA/cm2, while the current density turned to be the main factor when it reached up to 225 mA/cm2. A smooth, dense and uniform coating with Mn content above 20% (atomic fraction) could be obtained by pH value of 4.5 and current density of 125 mA/cm2. After a hydrogen-relief treatment and then an oxidation treatment at 800 ℃, the electroplated Co-Mn alloy coating might be transformed into a continuous MnCo2O4 spinel oxide film with a good compatibility to the substrate.

Abstract： Moffitt's developmental taxonomy theory categorized antisocial behaviors (AB) into two types, namely the life-course persistent and adolescence limited (AL). Adolescent antisocial behaviors, usually develop in the early puberty and end in late adolescence or early adulthood, occur more in youth group than LCP-AB. Maturity, in aspects of physical or psychological maturity, impacts the emergence, development and cessation of adolescent antisocial behavior. Physical maturity develops and strengthens AL-AB. Psychological maturity slows down and weakens AL-AB. The interaction between physical maturity and psychological maturity might strengthen or weaken AL-AB. The maturity gap between physical maturity and psychological maturity inhibits AL-AB. Further efforts are needed to expand different types of maturity research, improve the calculation methods of maturity, and investigate the intervention based on adolescent maturity characteristics.

Abstract： Objective To investigate the correlation of the changes in CD8 + CD28- T cell percentage with platelet (PLT) and D-dimer (D-D) levels in patients with multiple injuries (MI). Methods Twenty-six patients with MI, 31 with a single injury (SI group) and 26 healthy individuals were examined for peripheral blood CD8 + CD28- T cells and intracellular transformation growth factor-β1 (TGF-β1) and interleukin 10 (IL-10) contents using flow cytometry at 24, 48, and 72 h after the injuries. PLT and D-dimer levels were compared among the 3 groups. Results CD8 + CD28- T cells, TGF-β1 and IL-10 were significantly higher in MI group than in SI group and healthy control group (P<0.05) without significant differences between the latter 2 groups. The levels of PLT and D-D differed significantly among the 3 groups, the highest in MI group and the lowest in the control group. In MI group, CD8 +CD28- T cells, TGF-β1 and IL-10 significantly increased at 48 h after the injury (P<0.05) but decreased significantly at 72 h (P<0.05) compared with the measurements at 24 h. The levels of PLT and D-D trended to decrease with time after the injuries and showed significant differences among the 3 groups at any of the 3 time points (P< 0.05). CD8+CD28- T cells, TGF-β1 and IL-10 were all positively correlated with the levels of PLT and D-D in MI patients (r>0.70, P<0.05 for all comparisons). Conclusion In MI patients, CD8+CD28- T cell percentage and their cytokines tend to increase early after the injury but decrease significantly at 72 h in close relation with the changes of the coagulation function following the injuries.
