Vascular calcification, including intimal and medial calcification, is closely associated with a significant increase in cardiovascular diseases. Although increased understandings were achieved, people still know much more about intimal calcification than medial calcification because the latter doesn't obstruct the arterial lumen, commonly considered as a non-significant finding. We clarified the pathologic characteristic of medial calcification, its difference from intimal calcification, principally focused on its clinical relevance, such as diagnosis, nosogenesis, and hemodynamics. We underline the importance of identifying and distinguishing medial calcification, understanding its effect to local/systematic arterial compliance, and relationship to diabetic neuropathy. Recent studies emphasize do not ignore its predictive role in cardiovascular mortality. It is of great clinical significance to summarize the mechanisms of occurrence, lesion characteristics, diagnostic methods, pathogenic mechanisms, hemodynamic changes, and the distinction as well as association of intimal calcification with intimal calcification.

Objective To improve the training system of the combined education mode between professional master degree students of clinical medicine and resident standardization training (RST) in Zhe-jiang province, and improve the professional quality of medical graduate students. Methods A question-naire was designed through literature review and expert interview, and the data of 77 clinical training post-graduates were collected, and the effect of the training was evaluated by taking the reaction level, learning level, behavior level and achievement level of Ke's evaluation as the breakthrough point. Statistical analysis was performed by SPSS 20.0, and the mean score was used as the standard deviation. The scores were compared with t test, and the scores of multiple groups were made variance analysis. Results The RST attitude value in reaction layer was 9.26±1.08, RST content value was 29.29±4.36, RST teacher enthusiasm value was 11.13±2.17, RST experience value was 17.38±3.10, which indicated that residents' overall satisfaction to RST was high, but the satisfaction on teachers, evaluation and compensation was relatively low;The grade difference before and after RST in learning layer was statistically significant (P<0.05), indicating that before and after RST the grades were obviously improved, and the sense of belonging is high. The behave layer showed the residents' behavior changed obviously before and after RST (P<0.05), and their abilities in various aspects such as ward round and dealing with common diseases were largely improved;The result layer showed 77 graduate students had no medical accident and complaint , and all of them passed the annual assessment and participated in the research projects. Conclusion In general, RST graduate students are relatively satisfied with the plan, content and methods of the training, on the other hand, there are problems such as the absence of timely information feedback, teachers' poor enthusiasm, lack of effective competition mechanism, etc. Kirkpatrick Model made a comprehensive and objective eval-uation on graduate students RST from a overall perspective, and it can be introduced into the effectiveness evaluation for graduate students RST.
