Objective To analyze the cognition and demand of the residency training program among clinical medical students to provide scientific basis for the promotion of this policy.Methods From May 24 to 25,2015,a self-designed questionnaire survey was conducted on 645 undergraduate clinical medical students,who came from Zhengzhou University,Xinxiang Medicine College,Henan University.Data of cognition and demand of the residency standardized training were statistically analyzed using SPSS 22.0 software.Enumeration data were analyzed by chi-square test and abnormal distribution data based on Wilcoxon rank sum test.Results 616 valid questionnaires were recovered.259 undergraduate clinical medical students (42.00％) did not quite understand the resident standardized training policy and 225 (36.50％) did not known the policy at all.Before and after clinical practice,the cognition of the residency standardized training had statistically significant difference (x2=87.596,P=0.000),the knowledge of the policy (x2=10.939,P=0.012) and the degree ascending alleviate employment pressure (x2=29.349,P=0.000) were the main influencing factors of the clinical medical students' choices after graduation.Conclusion Improving medical students' understanding of the significance of medical education after graduation,and the integration of professional degree training and residency standardization training effectively helps to promote implementation of the policy.

Vigabatrin-associated brain abnormalities on magnetic resonance imaging (VABAM) is a relatively rare side effect of vigabatrin, most of which are asymptomatic. However, there will be extremely rare cases with hyperkinetic disorders, myoclonus, tremor, and acute encephalopathy under certain circumstances. VABAM is often underappreciated by physicians and its accurate incidence remains unclear. A female infant who was diagnosed with infantile spasms and required adrenocorticotropic hormone therapy accompanied by various antiseizure medicines was reported. Unfortunately, she became lethargic and her spasm deteriorated gradually after vigabatrin exposure. Her brain magnetic resonance imaging revealed abnormal signals bilaterally in the dorsal midbrain, thalamus, and rostral part of the pallidum. She had a seizure amelioration and became lively as a result of vigabatrin withdrawal. In the meanwhile, magnetic resonance imaging returned to normal. Attempts were made to discover the risk factors of VABAM and potential pathogenesis. Further understanding of the disease should contribute to decreasing misdiagnosis and making precise decisions.
