ABSTRACT
Cardiac surgery is the latest and fastest growing subject in surgery, which is character-ized by complex diseases and strong specialization.The standardized training of non cardiac surgery is short of time for the residents in cardiac surgery, and the teaching has certain complexity and particularity. The department of cardiac surgery of the Xinjiang Uygur Autonomous Region people's Hospital has analyzed the subject characteristics of the major, and explored the reform of cardiac surgery teaching. We adopted a variety of teaching forms to enhance clinical thinking ability and clinical practice ability as the focus of training, and strengthen clinical operation skills according to individual differences among residents. We improved the enthusiasm and initiative of the non-cardiac surgery residents to learn, training residents standardized,standardized diagnosis and treatment behavior,improve the quality of training.
ABSTRACT
Objective To screen, analyze and predict microRNAs (miRNAs) related to systemic scle-roderma (SSc). Methods Differentially expressed miRNAs between tissue samples from 3 patients with SSc and 3 normal human controls were screened with a gene chip including 924 miRNAs. Target genes regulated by differentially expressed miRNAs were searched with bioinformatics method. Finally, miRNAs related to SSc were predicted. Results There were 24 miRNAs differentially expressed between tissue samples of SSc and normal controls, including 9 up-regulated miRNAs and 15 down-regulated miRNAs. Literature review disclosed that SSc was associated with target genes regulated by hsa-miR-206, has-let-7g, hsa-miR-133a, hsa-miR-125b, hsa-miR-40-5p and hsa-miR-23b. In particular, 15 target genes regulated by hsa-miR-206 were closely correlated with the pathogenesis of SSc. Conclusions In lesions of SSc, there is an expression of miRNAs related to the pathogenesis of SSc, which may include hsa-miR-206 as well as 5 other miRNAs.
