Objective: To establish nutrition knowledge questionnaire items for Chinese adults by Delphi consensus study.
Methods: The framework system and preliminary items of nutrition knowledge questionnaire were established through literature review and experts consultation, considering the nutrition status and problems of Chinese people. Delphi method was used to conduct consensus analysis with 11 experts in related field involved to determine the nutrition knowledge questionnaire items.
Results: The active coefficients of consultation in two rounds were both 100%(11/11), and the authority coefficients of experts were 0.900. The average scores of all items were(4.67±0.28) and(4.80±0.21), the variation coefficients were 0.06 and 0.04, and the Kendall harmony coefficients were 0.261(χ~2=39.645, P=0.004) and 0.324(χ~2=43.122, P=0.001), respectively. After the second round of consultation, all selected items met the inclusion criteria. Finally, 20-item nutrition knowledge questionnaire were determined, including five dimensions of dietary recommendations, food characteristics, nutrition and health, food choices and food safety.
Conclusion: The Delphi consensus of nutrition knowledge questionnaire items for Chinese adults were basically achieved.

Juvenile dermatomyositis with emphasized vasculopathy is rare, but the most severe form of the disease, with a poor prognosis with relapsing and chronic course or, in some cases, lethal outcome. We present a case of a 19-year-old Caucasian female, who developed severe acute juvenile dermatomyositis with emphasized multisystem vasculopathy, including retinal vasculopathy and maculopathy (cotton-wool spots, retinal hemorrhages, macular edema) at the age of 8. Due to no response to standard treatment protocols and rapid worsening of clinical symptoms and laboratory findings, a TNF inhibitor (infliximab) was introduced after the third week of treatment resulting in complete normalisation of muscle enzyme levels and complete resolution of eye changes within the next 2 weeks with a gradual general recovery.
