Objective To investigate the cognition level and education demand of occupational protection knowledge among nursing students in clinical practice in the hospitals of Shanghai and analyze its related factors.Methods A cross-sectional survey involving 360 nursing students was conducted in Shanghai.The survey content included occupational protection knowledge,demand and suggestions about setting up occupational protection curricula.Results The mean knowledge score was 5～13 points,with an average of (9.33±1.62)points.In multiple regression models,the level of hospital and educational status were related factors for knowledge level.The occupational protection knowledge mainly from school education accounted for 59.4％,considering it necessary to set up occupational protection curricula accounted for 60.5％.Ways of acquiring occupational protection were:teachers integrating related knowledge into teaching,receiving related education before clinical practice,and being given warning before dangerous operation,accounting for 43.7％,30.8％ and 16.2％.Conclusions Nursing students require a comprehensive foundation course in occupational protection before they enter the clinical practice.This will help to ensure their physical and mental health.

A retrospective analysis was performed on one case of adult-onset type Ⅱcitrullinemia(CTLN2)caused by homozygous mutations of SLC25A13 genes.The patient,a 28-year-old male,had repeated limb convulsions for more than 4 years and worsened for 2 months.He usually liked to eat peanuts and meat.The brain MRI examination showed no abnormality,and anti-epileptic treatment was not effective.Further examination of blood aminotransferase,blood ammonia and citrulline were elevated,genetic testing showed that the SLC25A13 gene c.851_854del homozygous pathogenic mutation,the diagnosis was CTLN2,and the treatment was treated with a high-protein,high-fat,low-sugar diet and arginine,and there were no seizures followed up for half a year.Patients with recurrent seizures with special dietary preferences should be paid attention to the possibility of CTLN2,and genetic testing plays an important role in the diagnosis of CTLN2 and provides a basis for clinical diagnosis and treatment.
