This study firstly reviews the history and current situation of course construction, then combines closely with the objectives and the summary of current situation of the standardized residency training, and finally puts forward concrete countermeasures from the several angles, such as teaching objectives, teaching team development, teaching content and forms, as well as evaluation mechanism, advocating the promotion of problem-based learning (PBL), medical simulation teaching (MST), literature discussion and other teaching methods, encouraging the integration of humanities education and clinical guidelines into teaching, and adopting objective structured clinical examination + standardized patient (OSCE+SP) assessment method and conducting two-way assessment, so as to assist in the education development of the standardized residency training.

Objective To evaluate the condition of oxidative stress and immunosuppression in early stage of severe sepsis,and investigate the correlation between them. Methods A prospective random control study in-cluded patients group(n=51)and control group(n=31). The concentration of serum superoxide dismutase was measured by enzyme linked immunosorbent assay(ELISA),CD4+CD25+Treg% was measured by flow cytometry , respectively. The difference between two groups was compared and the correlation between parameters in patients group was evaluated. Results The concentration of serum SOD was lower than control group (P < 0.01). CD4+CD25+Treg% significantly high,compared to the control group(P < 0.01). There was no strong correlation be-tween parameters in patients group. Conclusion Oxidative stress and immunosuppression are exist in the early stage of severe sepsis.

This paper introduces the research and realization of an adaptive fetal electrocardiograph (FECG). We have developed an embedded system which takes the digital signal processor chip TMS320LF2407A as the core. According to the principle of adaptive noise cancelling(ANC), the ANC software algorithm is studied and realized to extract the FECG by non-invasive means, then the embedded system sends the data to the computer through the communication interface for real-time display, analysis and recording of the processing results. The experiments indicate that the design is reasonable and the instrument owns a good performance.
